1. System summary


1.4 Scope of functions of the connected Checkbox

The functions provided by CheckOpti depend on the scope offunctions of the connected Checkbox.

The functions described refer to devices of the Checkbox fam-ily with operating system version 1.2 to 3.1. With other de-vices or operating systems some of the functions, e.g. con-figuration tools or processing features, are not alwaysavailable.

Please noteIn order to match the functions of the Checkbox andCheckOpti:

� Always carry out the identification of the connectedCheckbox (�target system�) in the dialogue window�Project properties.�

The identification is absolutely necessary if CheckOpti is tofunction correctly.

2.1 Installing CheckOpti

In order to operate CheckOpti, you must install the softwareon the PC. Installation is carried out by means of a setup pro-gram.

If a version of CheckOpti is already installed, you should firstdeinstall this version.

2.1.1 Installing CheckOpti

Start installation with the program �Setup.exe� on the in-stallation CD ROM.

To do this, switch to the CD ROM drive, e.g. in Explorer. Startthe file with a double click.

First select the language in which CheckOpti is to be installed.Confirm the selection with �OK�.

Fig. 2/1: Installation program � language selection



Follow the instructions in the installation program. With�Next� you move to the next step; with �Back� you moveback to the previous step.

The installation program will lead you through the followingsteps:

1. Greetings from the installation program

2. Display current information on CheckOpti

3. Select the installation directory

4. Start the installation

5. Display the successful installation

6. If necessary: new start of the PC after an enquiry

When installation is completed, you will find the entry forstarting CheckOpti in the start menu under [Programs] [FestoSoftware] [Checkbox] [Festo CheckOpti ...].

2.1.2 Deinstalling CheckOpti

CheckOpti can be deinstalled with the aid of the function�Software� in the system control of Windows.

Proceed here as described in your Windows manual.



2.2 General instructions for operating CheckOpti

2.2.1 Creating the online connection

In order that CheckOpti and the Checkbox can communicatewith each other, they must be connected with the diagnosticcable type KDI-SB202-BU9. This is supplied with theCheckKon.

Connect the diagnostic cable to the following ports:

� the diagnostic interface (X1) of the Checkbox or to the�Diag� plug on the Checkbox Compact

� a serial interface COM1 or COM2 of the PC.

1 Diagnostic inter-face (X1) 1

Fig. 2/2: Connecting the Checkbox to the PC (example)

Please noteConnect the PC and the Checkbox with the diagnosticcable:

� without twisting

� without loops

� at a sufficient distance from current-carrying cables ordevices

You will then avoid transmission faults between the PC andthe Checkbox.



Please noteCheckOpti supports as standard the monitoring and opti-mizing of the parts test of a Checkbox. The connection tothe Checkbox is then no longer required.

� Remove the diagnostic cable as soon as you have fin-ished working with CheckOpti. In this way you will avoidoperating faults in the Checkbox.

� Note that the Checkbox operates only at a reduced partsrate in the diagnostic mode.

CautionIncorrect functioning may occur as a result of a differenttime reaction of the Checkbox.

Note that the Checkbox is in diagnostic mode when it isconnected to CheckOpti. Parts may therefore pass theCheckbox without being checked. The subsequent systemmay therefore be damaged.

The Checkbox transmits more information in the diagnosticmode than in the operating mode. The time required fortransmission will then be longer. No parts will be checkedduring the transmission period.

� Do not therefore operate the Checkbox at the full partsrate in the diagnostic mode. You can thereby preventunchecked parts from being delivered incorrectly.



2.2.2 Starting CheckOpti

Start CheckOpti by selecting the entry start menu under [Pro-grams] [Festo Software] [Checkbox] [Festo CheckOpti ...] in theStart menu.

CheckOpti starts with the dialogue window �Welcome toCheckOpti�.

3. Select the entry �via cable� in the list field �Connec-tion ...� under �Connection to Checkbox� in the dialoguewindow �Options� and activate the check box �Set con-nection automatically�.

4. Accept your entries with �OK�.

Further settings see section 3.2.1, �Settings in CheckOpti �Options�.



2.2.4 Determining the target system

A CheckOpti project must be adapted to suit the functions ofthe Checkbox used.

To do this you must determine the type (Identbox, Count-box, ...) as well as the software version of the Checkbox. Youmust perform this adaption process in the dialogue window�Project properties�.

Carry out the adaption for every new or modified Checkbox.The data ascertained or entered will be saved in the currentproject.

� Open the dialogue window �Project properties� in one ofthe following ways:

� The dialogue window will be opened automatically ifyou select the option �Manual creation� in the dia-logue window �Welcome ...� after starting CheckOpti.

� Select the command [Project properties] in the menu[Window].

When adapting the CheckOpti project to the target system inthe dialogue window �Project properties�, use the check box�Insert settings into project description�. In this way, theproperties ascertained will be accepted into the project docu-mentation.



Fig. 2/4: Project properties

Carry out the adaption with the connected Checkbox as fol-lows:

� Recommendation:With �Start� you can load the information of the Checkboxconnected to the PC (automatic identification).

� By selecting or entering the correct settings, you canenter the relevant information yourself.

Accept your entries with �OK�.



2.3 Working with projects

In order to document, reuse and archive the work carried outwith CheckOpti, you must save this work in projects.

A project contains the following general information:

� project documentation

� information on the target system

A project contains one or several sub-projects. A sub-projectdescribes a parts type (in the case of the Sortbox the partstypes of a sorting program). The following information issaved in a sub-project:

� learnt sample parts (with contour data)

� Teach-Data

� test parts (with contour data)

� configured tools

The sub-projects contain the parts-specific and type-specificinformation on one parts type or sorting program (only withSortbox: 2 ... 6 part types are grouped together in a sortingprogram).

Create a separate project or sub-project for each parts typeor sorting program (see dialogue window �Project prop-erties�, check box �Project file includes multiple sub-pro-jects...�).

All the information on a project is saved in a project file. Thishas the file extension �.cbp�. The name and the directorypath of the project file will be requested when the project issaved for the first time.



Manage your project files with the Windows Explorer. You cancopy, shift, delete or open these files in CheckOpti as desired.

Document your processed projects in the dialogue window�Project documentation� (see section 3.2.4). Enter all rel-evant information in order to simplify the later assignment ofthe individual projects.

Information on the Checkbox as well as on the sorting pro-grams with the Sortbox can be found in the Checkbox man-ual.



2.4 Printing

CheckOpti supports you in documenting your work with auser-friendly printing function.

Before printing, check the settings of the printer (command[Print setup] in the menu [File] ).

Use the command [Print] to print the contents of the currentwindow. Depending on the active window, the following in-formation will be printed:

Window Printed information

�Project documentation� The project data

�Part contour� The part currently represented

�Teach-Data� The Teach-Data of all orientations

�Feature properties� Settings of the currently representedfeature or configuration tool

�Feature graph� The currently represented featuresgraph

If necessary, check first the contents of the printout in thewindow �Print preview� (command [Print preview] in themenu [File] ).

Please noteUse only paper sizes �A4� or �Letter� in portrait format.Otherwise a correct printout is not ensured.



2.5 Importing and exporting data

In order to exchange projects or to use them again in otherprograms (e.g. in CheckKon or Microsoft Excel), you can im-port or export various components of the current project.

1. Select the command [Import] or [Export] in the menu[File].

3.2 Windows and dialogue windows

The following sections contain an overview of the most im-portant windows and dialogue windows in CheckOpti.

A description of the steps, which can be carried out withCheckOpti, can be found in the chapter �Working with Check-Opti�, section 4.1).

3.2.1 Settings in CheckOpti

Fig. 3/4: Dialogue window �Options�



General settings Meaning

Recording buffer Maximum number of sample parts or test parts to be recorded Ifthe maximum number of parts with �Sample parts� or �Test parts�is exceeded, the first parts recorded will be deleted.

Path to CheckKon Before you can start CheckKon via the tool bar of CheckOpti, youmust enter the program path to CheckKon.

Do not show values of deacti-vated features

With activated check boxes, the values of deactivated features arenot displayed for reasons of clarity.

Connection settings Meaning

Connection to Checkbox Type of connection:� via cable: CheckOpti creates the connection to the Checkbox via

a serial interface.� via modem: CheckOpti creates the connection to the Checkbox

via a modem.Further information on the connection between the PC and theCheckbox can be found in the CheckKon user manual.

Set connection automatically Only possible with connection via cable. In the case of an activatedcheck box, the interface and the baud rate are determined auto-matically. In the case of a deactivated check box, a connection tothe dialogue �Connection parameter� will be displayed.

Use signal tone on part recep-tion

During learning or testing: Outputting signal tones for parts re-ceived or for the next orientation

Delete parts with defect con-tour data automatically

Features and contour data are transferred separately by theCheckbox to CheckOpti. If the contour data are faulty when trans-ferred, they will be ignored by CheckOpti. In this case, CheckOptican use the features transferred from the Checkbox instead ofascertaining the features itself. If tools are used, no contour datais available for ascertaining. In most cases, it is therefore advis-able to delete defective contour data completely.

Use features that differ fromthe part contour

With certain parameter settings of the Checkbox, features ascer-tained by the Checkbox may differ from the contour data. Check-Opti then uses the transferred features instead of ascertainingthem itself from the contour data (e.g. if �Mask out medium range�is active, the feature �Length� is greater than can be recognized inthe contour).



�Connection parameter� The dialogue window �Connection parameter� is displayedwhen a connection is to be created to the Checkbox and theconnection parameters to the Checkbox are not ascertainedautomatically (see dialogue window �Options�).

1 Connect with:Select the serial inter-face used for con-necting to the Check-box

2 Speed:Baud rate at whichthe connection is tobe created

3 Timeout (s):Period in secondsduring which theCheckOpti waits for areaction from theCheckbox before acommunication faultcan be sent

4 Next:Start the selectedfunction with the setconnection para-meters

With the settings under �Type of Checkbox to be simulated(target system)� you can adapt the CheckOpti project to thefunctions of the Checkbox used (e.g. the use of configurationtools or the processing of features are only possible with theoperating system �Config� as from version 1.2).

Here you can register the type (Identbox, Countbox, ...) aswell as the software version of the Checkbox. The specifica-tion of the target system is saved in the current project.

Please noteIt is absolutely necessary to determine the Checkbox(target system) to be simulated in order that the scope offunctions of CheckOpti and the Checkbox can be adaptedto suit each other. If the Checkbox type and the operatingsystem version are not defined correctly, malfunctioningmay occur during the check.

With the check box �Project file includes multiple sub-pro-jects ...� you can define the division of the project into sub-projects. In the individual sub-projects you can process aparts type or a sorting program.

In the check box �Project file compatible to CheckOpti 1.0�you can process the project with an older version of Check-Opti.This option is only available if:

� the project is defined without sub-projects,

� the target system is not a Sortbox or a Checkbox Com-pact,

� the software version (operating system of the Checkbox)is ≥ 3.0.

By selecting one of the following options under �Influence ofa teach process on the Checkbox ...�, you can determine thereaction of the Checkbox to a new teach procedure.

Option Meaning

No change of manual editing(protected / locked)

The manually entered feature values are valid for the current featurein the orientation shown.The manually entered values are not protected in the Checkbox andwill be overwritten in a new learning procedure on the Checkbox.

Overwrite of manual editing(not protected/not locked) *)

The manually entered feature values are valid for the current featurein the orientation shown.The manually entered values are protected in the Checkbox againstoverwriting in a new learning procedure on the Checkbox.The modifications are saved in the Checkbox after transfer of theTeach-Data even after a new teach procedure. They can only bedeleted by a new transfer of the Teach-Data. This applies also to theconfiguration tools used.

With the window �Feature graph� you can examine the indi-vidual features for their suitability for the recognition pro-cess.

You can also represent the distribution (histogram) of thefeatures or deviation. In each case the number (sum) of thevalues within a value range will be shown as a horizontal bar.

The features suited for testing the orientation distinction ortype distinction are distinguished by narrow ranges and largegaps between the orientations or types.

All features with relatively narrow ranges (gap betweenorientations not necessary) are suitable for the quality check.

The feature values of the individual parts are marked in thegraph with a dot. The relevant current part is marked with alarge rectangle. Further selected parts are marked with largedots.

In the test parts view, bad parts are shown crossed through(red lines/crosses).

4.1 Method of working with CheckOpti

The following list provides an overview of the steps you willusually take when working with CheckOpti.

1. Start CheckOpti as described in section 2.2.2, �StartingCheckOpti�.

Select the option �Manual creation� in the window �Wel-come ...�.

Then carry out the identification of the connected Check-box in the window �Project properties� as described insection 2.2.4, �Determining the target system�.

2. Teaching parts via the serial connection (see section 4.2).

Normal good parts are shown to the Checkbox (sampleparts). The contours registered are loaded into CheckOptifor the teach procedure, where they can be displayed.

Checking the Teach-Data ascertained from the parts con-tour of the sample parts. If necessary, the Teach-Data canbe processed (e.g. delete incorrectly learnt parts).

3. Testing parts via the serial connection (see section 4.3).

Monitored testing of parts (as in normal operation, nospecial selection). The contours registered are transferredto CheckOpti, where they are tested and can be displayed(test parts).



4. Evaluating the Teach-Data with regard to reliability (evalu-ation, see section 4.4). For this purpose evaluate the testparts if they have been graded correctly as being good orbad and evaluate their features and deviations (e.g. in thewindow �Feature graph�).

5. Optional: optimizing the parts test by manually adaptingthe features or by using configuration tools (see sec-tion 4.5).

6. Optional: documenting and printing out the project (seesection 4.6).

7. Transferring the Teach-Data to the Checkbox. Saving theproject (see section 4.7).

Alternatively, you can start the Project Wizard which will leadyou interactively through the most important steps (see sec-tion 5.1, �Working with the Project Wizard�).

As a further possibility, you can open the guide for the man-ual project creation. This will display the most important worksteps interactively in the form of a check list (see section 5.2).



4.2 Teaching parts with CheckOpti

4.2.1 Preparing the Checkbox

Prepare the Checkbox as follows:

1. Mount the Checkbox ready for operation.

2. Switch on the Checkbox.

3. The Checkbox must be connected to the PC as describedunder �Creating the online connection� (section 2.2.1).

4. If necessary, adjust the Checkbox with CheckKon to theparts to be tested (see CheckKon manual).

5. Checkbox in Stop status.

6. Start CheckOpti (if not already started).

Select the option �Manual creation� in the window �Wel-come ...�.

Carry out the identification of the connected Checkbox(see �Determining the target system�, section 2.2.4).

Provide suitable sample parts with the following properties:

� The sample parts show all the properties which a partclassified as �Good� should possess.

� Use different sample parts with a usual scatter of the fea-tures. With the scatter of the sample parts, you can deter-mine the extent to which test parts classified as �good�may later deviate from each other.



4.2.2 Teach procedure

When you have prepared the Checkbox, start the teach pro-cedure.

Please noteThe teach procedure is not carried out by the Checkbox,but by CheckOpti on the PC.

The teach procedure is not, therefore, effective until theTeach-Data have been transferred to the Checkbox (seesection 4.7, �Transferring the Teach-Data to the Check-box�).

Note that good parts can therefore be blown down andbad parts can reach the good parts position.

Please noteIf transfer of the contour pictures is deactivated (icon �Re-ceive parts contour on/off� in the tool bar), the tools inCheckOpti cannot be processed or only to a limited extent.

1. Select the command [Teach via connection] in the menu[Action]. The current orientation is displayed under �Toler-ance�.

2. Make sure that the Checkbox is in Start status and theconveyor unit runs.

3. Set the desired orientation (Countbox, Identbox, Check-box Compact) or the desired parts type (Sortbox) with thebuttons �+� and �-� in the window �Checkbox panel�.

4. Place the sample parts on the conveyor belt one after theother according to the set orientation or the set partstype.

Wait until the data have been transmitted completely be-fore placing the next part on the conveyor belt (bleeptone).



Pay attention to the positioning of the sample parts.

� These should be positioned exactly like the parts to betested later. You need not be too careful at first.

� Carry out the teach procedure as realistically as possible.Use e.g. the conveyor device intended for this purpose(for supply).

� In cases where particularly different variations of the as-certained parts contour (view) are permitted or are poss-ible in an orientation, you should show the �extreme�variations or as many different variations as possiblewhen teaching.

Recommendation:Show at least 10 parts of the current parts type per orienta-tion and parts type. If possible, use different parts.

If necessary, observe the graph in the window �Teach-Data�.This shows the C value. If this value changes only slightly,then sufficient scatter has usually been achieved in the cur-rent orientation when the sample parts are learnt.

Please noteTransmission of the contour pictures can lead to a modi-fied time reaction of the Checkbox. Parts may then not beblown down correctly and bad parts may reach the goodparts position without being checked.



5. Repeat steps 3 and 4 for all the orientations and partstypes (parts types only with Sortbox).

6. Switch the Checkbox into the Stop status.

7. Conclude the teach procedure with �Stop� in the window�Checkbox panel�.

The learnt sample parts are shown in the window �Part list�.After the teach procedure, you can perform one of the follow-ing steps:

� Start the parts test (see section 4.3, �Test parts withCheckOpti�).

� Check the completed teach procedure in respect of partstype, orientation and quality (see section 4.4, �Evaluatingthe Teach-Data�).

If necessary, you can optimize the Teach-Data (see sec-tion 4.5, �Optimizing the Teach-Data�).

� Document your work (see section 4.6, �Documenting andprinting the project�).

Load the ascertained Teach-Data into the Checkbox (seesection 4.7, �Transferring the Teach-Data to the Check-box�).



4.3 Testing parts with CheckOpti

4.3.1 Basic information on parts testing

By means of the parts testing with CheckOpti, you can checkthe success of the teach procedure. The test parts are thentransferred to CheckOpti.

This offers the following possibilities:

� Displaying the tested parts with their grading (good part,bad part, orientation)

� Displaying the contours of the tested parts

Prerequisites for the parts testing:

� Sample parts or Teach-Data must be loaded into Check-Opti. For this you have:

� carried out the teach procedure for the relevant partsas described under �Teaching parts with CheckOpti�;

� or opened an existing project file;

� or loaded the Teach-Data from the Checkbox (menu[File], command [Teach-Data Manager] );

� or loaded contour data of the sample parts or Teach-Data from a file (menu [File], command [Import] ).

� The Checkbox must be prepared as described under�Teaching parts with CheckOpti�:

� the Checkbox must be in the Stop status.

� Suitable test parts must be available (see �Test pro-cedure�, section 4.3.2).



4.3.2 Test procedure

When you have prepared the Checkbox, you can start the testprocedure.

Please noteThe teach procedure carried out in the previous step doesnot yet have any effect in the Checkbox, but has been car-ried out by CheckOpti on the PC.

The teach procedure is not, therefore, effective until theTeach-Data have been transferred to the Checkbox (seesection 4.7). Note that good parts can therefore be blowndown and bad parts can reach the good parts position.

Please noteIf transfer of the contour pictures is deactivated (icon �Re-ceive parts contour on/off� in the tool bar), the tools inCheckOpti cannot be processed or only to a limited extent.

1. Select the command [Test parts via connection] in themenu [Action]. The current orientation is displayed under�Tolerance�.

2. Make sure that the Checkbox is in Start status and theconveyor unit runs.

3. If necessary, set the desired tolerance for CheckOpti in thewindow �Checkbox panel� with the buttons �+� and �-�.

4. Place the test parts on the conveyor belt one after theother.



Pay attention to the positioning of the test parts.

� Use test parts which correspond approximately in theircomposition to the parts to be tested later in AUTO mode,i.e. good, bad and incorrectly orientated parts.

� The test parts should be positioned exactly like the partsto be tested later in AUTO mode. Avoid special care inpositioning. If possible, use the conveyor device intendedfor this purpose.

� Wait until the contour image has been completely trans-mitted before placing the next part on the conveyor belt(bleep tone).

Recommendation:Check a sufficient number of parts, in order to obtain a repro-ducible result. Show, e.g. 6 parts recognized as good as wellas 6 bad parts per orientation.

Please noteTransmission of the contour pictures can lead to a modi-fied time reaction of the Checkbox. Parts may then not beblown down correctly and bad parts may reach the goodparts position without being checked.

5. When you have checked a sufficient number of parts,switch the Checkbox into the Stop status.

6. Conclude the teach procedure with �Stop� in the window�Checkbox panel�.

The test parts are shown in the window �Part list�. Check herethe grading of the parts according to good parts, bad parts oraccording to their orientation.



After the test procedure, you can perform one of the followingsteps:

� Check the completed teach procedure in respect oforientation and quality (see section 4.4, �Evaluating theTeach-Data�).

If necessary, you can optimize the Teach-Data (see sec-tion 4.5, �Optimizing the Teach-Data�).





4.4 Evaluating the Teach-Data

By means of the Teach-Data, we can obtain a reliable gradingof the parts to be tested according to the following criteria:

� orientation

� parts type (only with Sortbox)

� quality (e.g. dimensional accuracy of the parts)

Evaluate the Teach-Data therefore in respect of their reliability(evaluating the teach procedure). A description of the individ-ual methods or criteria for evaluation can be found in thefollowing sections:

� Visual check of the sample parts (correct and completecontour image)

� Checking the parts types (only with Sortbox)

� Differentiating the orientations

� Evaluating the feature scatter

� Checking the bad parts

� Influence of tolerance



After evaluating the Teach-Data, carry out one of the followingsteps depending on the result of the evaluation:

� If necessary, repeat the teach procedure or learn furthersample parts (see section 4.2, �Teaching parts withCheckOpti�).

� If necessary, you can optimize or process the Teach-Data,e.g. by inserting configuration tools (see section 4.5,�Optimizing the Teach-Data�).





4.4.1 Visual check of the sample and test parts

Sample parts

Check the individual sample parts in the window �Part con-tour�.

Pay attention here especially to teach errors such as:

� incorrect setting of the orientation (this may be the causeof error E20 � Orientations cannot be distinguished);

� incorrect parts type (error E21, only with Sortbox);

� inaccurate or incorrect positioning of a part;

� incorrect or unsuitable sample parts;

� cut-off contour images (transmission fault).

Correct the teach errors as described under �Optimizing theTeach-Data� (see �Editing the sample and test parts�, sec-tion 4.5.1).

Test parts

Check the test parts in the window �Part contour�, e.g. ac-cording to the following:

� Have the orientations or parts types been recognized cor-rectly?

� Is the grading of the parts classified as good correct?

� Is the grading of the parts classified as bad correct?

If these points are not fulfilled, you can ascertain the causeswith the methods or criteria described in the following sec-tions.



4.4.2 Differentiating the orientations and parts types

In order that the orientation of parts can be checked reliably,the features ascertained for the individual orientations mustdiffer from each other to a large extent. With Sortboxes thefeatures of the parts types must also differ.

It must be possible to distinguish each orientation of a partstype from each orientation of the other parts types. The fea-ture ranges must be distinguished, exactly as with theorientations.

The window �Feature graph� shows the sequence of the dif-ferent features ascertained.

� Check to see if there is at least one feature in which thevarious orientations differ from each other to a very largeextent (narrow ranges of the coloured bars with largegaps between).

� Make sure in particular that orientation 1 (the �goodparts� orientation) differs to a very large extent from allother orientations in at least one feature.

If these criteria are not fulfilled, you must optimize or processthe Teach-Data (see �Optimizing the Teach-Data�, section4.5), e.g. by:

� inserting configuration tools

� editing the features



Example of differentiating the orientations

The following diagram shows an example of differentiatingthe orientations:

1 Range, min./max. li-mits of the feature inthe individual orienta-tions

2 Range of features fororientations 1 and 2

3 Range of features fororientation 3

4 Parts with orienta-tion 3

456

Fig. 4/1: �Feature graph� window - differentiating the orientations

The range of orientation 1 differs considerably from orienta-tion 3. However, this is not the case with orientations 1 and 2.

If no other feature fulfils this criterion, the Teach-Data mustbe optimized, e.g. by insertion of a configuration tool.



Example of differentiating the parts types (Sortbox only)

The following diagram shows an example of differentiatingthe parts types:

aA Parts with parts type 2 and orientation 1

aB Parts with parts type 1 and orientation 2

aC Parts with parts type 1 and orientation 1

Fig. 4/2: �Feature graph� window - differentiating the parts types



The ranges of the orientations for parts type 1 differ consider-ably from those of parts types 2 and 3. However, this is notthe case for orientation 1 of parts types 2 and 3 (the �bars�2/1 and 3/1 overlap).

If no other feature fulfils this criterion, the Teach-Data mustbe optimized, e.g. by insertion of a configuration tool.

In the window �Teach-Data� the entries in the column �Separ-ates� show which features are best suited for separating theorientations or parts types.

4.4.3 Evaluating the scatter

Check the sequence of the scatter (C-value) in the window�Teach-Data�:

� A �jump� in the C-value indicates an incorrectly learntpart.

� Optimum: the sequence of C-values rises at first, thenevens out.

If there are irregularities in the C-values, check the learntsample parts (see �Visual check of the sample and testparts�, section 4.4.1). Check in particular the sample part onwhich the jump has occurred.



4.4.4 Checking the bad parts

Check the test parts with regard to their grading.

To do this, display the individual parts in the window �Partcontour�.

� Check whether the grading of the parts is correct.

� With parts classified as bad, the features which led to thisgrading are marked. The relevant icons indicate, e.g. thedirection of the deviation.

� If you have also tested faulty parts, check whether thesehave also been recognized as bad.

4.4.5 Influence of tolerance

Check the influence of tolerance on the grading of the testparts.

To do this, vary the tolerance in the window �Teach-Data�. Bya minor modification of the tolerance (e.g. ± 2 steps), thegrading of the parts in the window �Part list� should notchange. This can be rated as a stability criterion of the test.

The normal tolerance setting is 5% (standard tolerance of theCheckbox).



4.5 Optimizing the Teach-Data

If the result of the evaluation does not fulfil expectations, youcan optimize the Teach-Data.

The possibilities for doing this depend on the target systemset.

If you are using a Checkbox with software version type Configas from version 1.2, the following possibilities are available:

� processing sample and test parts.

� Insert configuration tools.

� Edit features.

A description of the individual methods or criteria for evalu-ation can be found in the following sections:

Always check the success of the optimization. To do this,carry out a regrading of the Teach-Data.

If the optimization and regrading of the Teach-Data are suc-cessful, carry out the following steps:

1. Document your work (see �Documenting and printing theproject�, section 4.6).

2. Load the Teach-Data into the Checkbox (see �Transferringthe Teach-Data to the Checkbox�, section 4.7).



4.5.1 Processing the sample and test parts

You can process the sample and test parts in the window�Part list� (notes on the window �Part list� can be found insection 3.2.2):

� Modify the orientation of incorrectly supplied sampleparts.

� Delete incorrect or unfavourable parts.

� If necessary, accept characteristic test parts as sampleparts or vice versa (copy or move).

� Invalidate sample parts with the icon �Ignore parts atteach process�. In this way, these parts will not be con-sidered when the Teach-Data are ascertained (marked bya red �T�, orientation �0� or �Part is ignored�).

� In special cases, you can create further parts by superim-posing the contours of selected parts (menu [Action],commands in sub-menu [Add new parts] ).

Overlay Function

OR Generates a new part from the selected parts. Onthis new part the image points belong to theparts contour which exists on at least one of theselected parts.

XOR Only for use with 2 selected partsGenerates a new part from the selected parts. Onthis new part the image points belong to theparts contour which exists on only one of the se-lected parts.

AND Generates a new part from the selected parts. Onthis new part the image points belong to theparts contour which exists on all of the selectedparts.



Example:Create a new part by means of the �OR� link from all partswith orientation 1 and all parts with orientation 2. Thencreate a further part from both new parts with the �XOR�link.This part now shows the characteristic differences be-tween orientations 1 and 2.

� Process the parts contour. In many cases, modification ofthe parameters, which influence the registered parts con-tours, can influence the recognition. You can set these forthe Checkbox with CheckKon (see CheckKon manual).CheckOpti offers the possibility of judging the effects ofthese settings without registering the parts again. Youcan simulate the setting of the parameters with the com-mands [Edit part contour] in the menu [Action] for theselected sample or test parts in CheckOpti (see also de-scription of the commands in chapter 3).

If you wish to accept the new settings permanently, setthese on the Checkbox with CheckKon.



4.5.2 Configuration tools

If the standard features are not sufficient for reliable recogni-tion of the parts, you can supplement these with additionalfeatures.

Insert the suitable tool when requested. The maximumnumber of tools depends on the target system set (operatingsystem and type of Checkbox).

Use tools when, e.g.:

� the contour differences are too small to recognize theorientation and/or the quality reliably

� the reliability of the test is to be improved

� a quality test for a certain small area in the contour is tobe determined This depends on the test criteria of therelevant part.

The configuration tools react like all other features when theyhave been installed. They are learnt like the other featureswith the aid of the sample parts during the learn procedure.

Like every other feature, they can grade a part as being ofgood or bad orientation and/or quality. They are also in-fluenced by the set tolerance.

Please noteConfiguration tools which have been set up are not lostwhen a teach procedure is carried out on the Checkbox,they are simply learnt again like the other features.

In order to remove configuration tools from the Checkbox,you must transfer new Teach-Data to the Checkbox withCheckOpti or CheckKon (without configuration tools or withnew configuration tools).



Please noteIf only the quality is to be tested and not the orientation:

� In the case e.g. of two horizontally symmetric orienta-tions, you must set up two tools horizontally symmetric(corresponding to the symmetry of the orientations).

The choice of the correct configuration tool depends on theindividual requirements of the parts.

To do this, observe and compare the contour images. Find thelocation at which the quality is to be tested and position thetool there.

A description of the various configuration tools can be foundin section 6.1.

Inserting the configuration tools

Insert the configuration tools in the window �Part contour�.

� To do this, select the desired tool type in the menu[Action] [Add Config tool] or click on the appropriate iconin the tool bar of the window �Part contour�.

The inserted tool is shown in the contour image.

...



Click on the tool. The tool will then be activated. The prop-erties of the tool will be shown in different colours:

Colour Meaning

red Represents the features found on the tool

pink Indicates a selection of one of the features found(e.g. the smallest distance out of several distances)

yellow Is used for representing help lines (e.g. for dimension-ing)

blue Is used for representing the position and suspensionfunction

green Search lines (for measuring tools): Defined lines alongwhich the characteristic transitions for the measuringtools are ascertained

The window �Feature graph� shows the values of the featuredefined by the tool.

With a double click on the tool, you can open the relevantwindow �Feature properties� for editing the tool settings.

By dragging with the mouse, you can shift the tool. When thetool is active, you can adapt the size with the aid of the grip-ping devices on the border lines.

Editing the configuration tools

In order to edit the configuration tools, open the dialoguewindow �Feature properties�.



4.5.3 Editing the features

In special cases you can manually edit the ascertained Teach-Data.

� You can deactivate the feature (is not considered whenthe Teach-Data are ascertained or during the test).

� Modify the weighting of the feature for the parts test bysetting an individual tolerance factor:

Small value: The feature is toleranced more nar-rowly and thereby tested more strictlythan features with greater tolerancevalues (e.g. length).

Large value: The values for the feature may deviateto a greater extent.

� As a special case, you can enter directly values for thepermitted min./max. limits or the average value of thefeature.

Select the desired feature in the window �Feature prop-erties�. Carry out the desired settings in the tab �Settings�(see section 3.2.3).



Notes on editing the features can be found in section A.2 or inthe description of the dialogue window in section 3.2.3.

Describing the features

Feature Meaning

Length_x Length of the registered contour surface(x-direction)

Height_y Height of the registered contour surface(y-direction)

Area Number of pixels of the registered contour surface

Circumf. Circumference of the registered contour surface

Area-x/2 Number of pixels of the registered contour surfacefrom start to half length

Area-y/2 Number of pixels of the registered contour surfacefrom below to half height

CG_co_x X-coordinate of the surface centre of gravity

CG_co_y Y-coordinate of the surface centre of gravity

Pol.min. Minimum polar distance, smallest distance of sur-face centre of gravity to outer contour

Pol.max. Maximum polar distance, greatest distance of sur-face centre of gravity to outer contour

Feat_11 Special contour test feature

Feat_12 Special contour test feature

... With each inserted configuration tool an appropri-ate additional feature is defined

Most features are also represented graphically in the window�Part contour�.



4.6 Documenting and printing the project

Document your processed projects in the dialogue window�Project documentation�. Enter all relevant information inorder to simplify the later assignment of the individual pro-jects.

When adapting the Checkbox to the target system in the dia-logue window �Project properties�, use the check box �Insertsettings into project description�. In this way, the propertiesascertained will be accepted into the project documentation.

A description of the dialogue window �Project documenta-tion� can be found in section 3.2.4.

If required, you can print out the relevant information forclear archive purposes.



4.7 Transferring the Teach-Data to the Checkbox

When the Teach-Data are transferred to the Checkbox, thedata created with CheckOpti and the tools which have beenset up, will be installed on the selected type memory.

The Checkbox checks all incoming parts with these Teach-Data.

Please noteThe contours of the sample parts, from which the Teach-Data are ascertained, must be created with the sameCheckbox and the same Checkbox parameter settings,onto which the created Teach-Data are then loaded.

In particular, modifications with CheckKon to the followingparameters make a complete new teach procedure necess-ary:

� exposure time, grey value threshold

� encoder to line frequency ratio

� upper and lower limit of viewing area

� conveyor belt speed (without encoder)

� parameters in �Extended influence of picture creation�(see CheckKon).

Please noteTools and special settings in the Teach-Data, which aretransferred to the Checkbox, remain saved on the Check-box even after a new teach procedure.

As from operating system 3.0, the Checkbox shows �tool�in the LCD display when a tool exists on a type memoryand the teach mode has been activated for this.

The installed tools and settings are not modified until anew transfer of Teach-Data takes place. With the TeachData Manager you can also delete the defined tools andsettings directly.



Please noteTransfer Teach-Data to the Checkbox only if the set targetsystem corresponds to the connected Checkbox. If necess-ary, carry out the identification in the window �Projectproperties�.

Load the Teach-Data into the Checkbox as follows:

1. Open the dialogue window for transferring the Teach-Dataand settings into the Checkbox with the command [Teach-Data Manager] in the menu [File].

2. Select the type memory into which the Teach-Data are tobe loaded under �Teach-Data�.

3. Start the download with �Copy >� or delete the Teach-Dataon the Checkbox with �Delete >�.

Please observe the warnings or instructions shown.

5.1 Working with the Project Wizard

5.1.1 The function of the Project Wizard

The Project Wizard conducts you interactively through all thesteps which are required for a normal teach, test and optimiz-ing procedure with CheckOpti.

The scope of functions of the steps performed corresponds toa large extent to the procedure described in sections 4.2, 4.3,4.4, 4.5, 4.6 and 4.7 .

Fig. 5/1: The Project Wizard

With the aid of the Project Wizard, even inexperienced userscan work easily, fast and in a comfortable manner with Check-Opti.

5. Wizards


5.1.2 Starting the Project Wizard

You can start the Project Wizard as follows:

� After starting CheckOpti:Select the option �Project Wizard� in the dialogue window�Welcome ...� and confirm with �OK�.

� At any other moment:Select the command [Project wizard] in the menu[Wizards].

Within the Project Wizard you can navigate between the indi-vidual steps with the buttons �Next� and �Back�.

If the button �Next� is inactive, an entry is missing in the cur-rent step. This entry is necessary in order that you can con-tinue.

A lot of steps, e.g. identification of the Checkbox, are carriedout automatically by the Project Wizard.

5. Wizards


5.2 Wizard for manual project creation

CheckOpti offers you the possibility of creating projects man-ually and of processing them with the aid of a check list.

With the command [Wizards] [Wizard for manual project cre-ation], you can display a check list in the lower part of theCheckOpti window. All the necessary processing steps arelisted in this window.

5.4 Statistic judgement of a feature

With the Wizard �Statistical judgement of a feature� you canascertain the resolution, the repeatability (accuracy) and therepetition accuracy of the parts test and create target valueranges in the Teach-Data.

Ascertained value Description

Resolution Measured value (e.g. length in mm) di-vided by the medium feature value(number of pixels).

Repetition accuracy Measuring uncertainty (deviation ofmeasured value) with repeated measure-ment of a measured value.

Uncertain assignment Percentage of the parts with which noclear assignment of the parts is possibledue to the current repetition accuracy (yel-low range of the graph in step 3 of the Wiz-ard, Fig. 5/7 or Fig. 5/8).These parts may possibly be returned for arepeated parts test. The effective goodpart rate will drop then.

Proceed as follows:

1. Measure as accurately as possible a single selectedsample part, e.g. with a caliper gauge or other suitabletool.

2. Show the measured sample part at least 50 times in suc-cession in the preferred orientation on the Checkbox, sothat the part exists at least 50 times as a sample part withorientation 1 in the window �Part list�.

3. Start the Wizard with [Wizard] [Statistical evaluation of afeature].

Please noteThe tools remain in the Checkbox after transfer of theTeach-Data even after a new teach procedure. The per-mitted feature ranges of the tools are adapted accordinglyto the teach procedure.

The tools can be deleted with CheckOpti by means of anew transfer of the Teach-Data (without tool).

For the tools you will find appropriate projects in the sub-di-rectory �Demo� of the program directory of CheckOpti.



6.2 VStrip tool

The VStrip tool calculates the area of the parts contour withina horizontally limited range. This results in a vertical strip(Vertical Strip).

Like the other features, this area then provides an additionaltest feature.

The distances between the references and the limits are en-tered in pixels.

The limits of the area, i.e. the left and right-hand limits, canbe defined in various ways. These limits refer to the start ofthe parts (left in CheckOpti) and/or to the end of the parts(right in CheckOpti).

The distances to the references are represented in the case ofa selected displayed VStrip tool as blue, horizontal bars, thecalculated area is marked in red.

Possible exception:If e.g. a contour section to the left of the centre is to betested, but the manufacturing tolerances on the test part aremeasured from the right and are therefore usually less. In thiscase select �... from right ...� both for the start and the end,although the VStrip tool lies to the left of the centre.

The horizontal reference is usually specified absolutely. Thissetting is available for all operating systems type Config asfrom version 1.2.

Horizontalreference

Meaning Usual application

absolute, from left(part begin / x = 0)

The position of the VStrip tool refers to theabsolute start of the part (always x = 0)

The absolute position isused, e. g. when the fea-ture to be defined is always

absolute, from right(part end)

The position of the VStrip tool refers to theend of the part (corresponds to the largestx-coordinate of the current contour)

ture to be defined is alwaysat the same horizontalposition in the parts con-tour.



As from OS Config version 3.1 the horizontal reference canalso be specified relatively. This is defined in the tab �Hori-zontal suspension�.

Horizontalreference

The position of the tool can adapt itself in thehorizontal direction to the current parts con-tour. The �horizontal suspension� can takeplace �from left� or �from right� (in respect

1) See tab �Horizontal suspension�. The tab is only shown if at least one relative reference has beenselected.

2) Available for Checkboxes with operating system type Config, as from software version 3.1.

The range, from which the relative reference value is calcu-lated, is defined by a horizontal strip. This is related to thex-axis (y = 0). Within the range �Begin in line� to �End in line�the search is now made for the first occurrence of the partscontour according to the specification �from left� or �fromright�. The position found serves as the horizontal referencefor the horizontal position of the tool.

Example of absolute reference:

Before a QS plug connector is forwarded to the automaticpacking machine, a check is to be made to ascertain whethera seal has been fitted and whether it is positioned correctly. Inthis case the orientation is not important. A check is made ofthe quality.

Two orientations of the part are carried out:

Orientation 1 (good) Orientation 2 (good) Orientation 2 (bad)

Fig. 6/5: Orientation with the VStrip tool

The following configuration tools are specified:

� Left-hand VStrip tool (references �absolute from left� and�absolute from left�).

� Right-hand VStrip tool (references �absolute from right�and �absolute from right�), all other settings identical tothe left-hand VStrip tool.

Tip for creating symmetric suspensions:

1. Select the tool with the mouse and create a copy of thetool in the clipboard with the command [Edit] [Copy].

2. With the command [Edit] [Paste] you can open the dia-logue window �Options for paste config tool�.

3. Select the option �Flip horizontal� and confirm with �OK�.The new tool will be inserted symmetrically on the otherside of the part.



Checking the reliability of the orientation test:

Fig. 6/6: Orientation test

The good parts of orientations 1 and 2 are clearly and reliablyseparated by the feature Area-x/2 (area left of part centre).

This is not at all important for the task in question. However,as the features of the tools must be compared with the cor-rect set of Teach-Data (orientations 1/2), the orientationsmust be correctly recognized.

If this is not the case, a part e.g. with orientation 1 could in-correctly be checked with the Teach-Data for orientation 2.



Please noteEven if only the quality is to be checked, it will not sufficeto learn only one orientation in which both alignments ofthe tool are shown.

In this case the ranges of the feature values, normally sep-arated by the orientation, would be grouped together. Inthis way the reliability of the quality check would be con-siderably impaired.

If possible, the individual orientations must always belearnt separately.

Checking the reliability of the quality test:

Fig. 6/7: Quality test of orientation 1

Orientation 1 (parts 1 to 5 with seal ring) is reliably recog-nized (feature values are clearly within the permitted range).

The feature values of parts 6 to 12 (without seal ring) areclearly outside the permitted range.



The same applies to orientation 2 (parts 13 to 17 without sealring, parts 18 to 22 with seal ring):

Fig. 6/8: Quality test of orientation 2

The required test is therefore possible.



Example of relative reference:

On a rotary part, a recess is to be checked irrespective of anyburr which remains when it is cut off.

Settings in the tab �Position�:

� Start in row:

� Horizontal position: 106 (pixels)

� Horizontal reference: relative from left to horizontalsuspension

� End in row:

� Horizontal position: 125 (pixels)

� Horizontal reference: relative from left to horizontalsuspension

The suspension of the VStrip tool is laid on a burr-free area ofthe start of the part, e.g. when the total diameter of the partsranges from approx. 80 to 240 in the upper (flat) area of thefront surface.

Settings in the tab �Horizontal suspension�:

� Horizontal suspension for �Start in row� and �End in row�:

� Begin in line: 180 (pixels)

� End in line: 240 (pixels)

Within this range a search is now made for the first occur-rence of the parts contour according to the specification�from left� or �from right�. This position serves as the hori-zontal reference for the horizontal position of the feature.



The thus resulting position of the tool is calculated as follows.

Resulting start of the tool = 106 + Xwith X = x-coordinate of the first contour element in

the vertical strip between y = 180 andy= 240

Resulting end of the tool = 125 + Xwith X = x-coordinate of the first contour element in

the vertical strip between y = 180 andy= 240

In this way the VStrip tool always refers to the front of thepart, irrespective of any burr.

without burr with burr

6.3 CTool

The CTool ascertains features from an transition of the con-tour of a part.

The following features can be ascertained:

Feature Meaning Typical application

Height difference Determines the maximum difference in heightwithin the horizontally limited area along the con-tour.

e.g. checking a recess

Maximum value1) Determines the maximum height within the hori-zontally limited area along the contour.

e.g. checking the height ina certain area

Mean value Determines the average height within the hori-zontally limited area along the contour.

e.g. local height check

Minimum value1) Determines the minimum height within the hori-zontally limited area along the contour.

e.g. checking the height ina certain area

Angle of fitted line1)

Determines the angle of the equalizing line withinthe horizontally limited area along the contour.

e.g. checking an angle in acertain area

Scalar length(curve length)

Determines the length along the contour withinthe horizontally limited area.

e.g. making sure there is athread


Scalar length (curve length) Height difference Angle of fitted line

Example of absolute reference:

A hollow screw is to be checked for orientation and quality.

The following is checked in orientation 1:

� Is there a thread (scalar length)?

� Is the depth of the recess correct (difference of height)?

Parts with orientation 2 are to be rejected when they arepassed through again.

The task can be solved with 3 CTools:

� Scalar length (arc length)

� Difference in height

� Mean value

Orientation 1, everything OK Orientation 2, everything OK

6.4 ROI tool

The ROI tool calculates the area of the parts contour within aparallelogram, an ellipse or between a parallelogram and anellipse.

Like the other features, this area then provides an additionaltest feature.

Fig. 6/15: ROI tool

The size of the ROI tool is defined by its width, height and bythe angle to the horizontal. The position of the ROI tool is de-termined by horizontal and vertical references.

The references are represented in the case of a selected dis-played ROI tool as blue, horizontal bars, the calculated area ismarked in red.

Determining the horizontal position and the width

The position of the tool in the horizontal is determined by thedistance to the start of the parts (from the left) or to the endof the parts (from the right).

Select the reference of the distances under �Horizontal refer-ence�:

The horizontal reference is usually specified absolutely. Thissetting is available for all operating system type Config asfrom version 1.2.

The left-hand limit refers to the start ofthe parts

The contour section to be exam-ined lies left of the centre


The right-hand limit refers to the end ofthe parts

The contour section to be exam-ined lies right of the centre

The absolute position is used, e.g. when the feature to be defined is always at the same horizontalposition in the parts contour.

As from operating systems Config version 3.1 the horizontalreference can also be specified relatively. This is defined inthe tab �Horizontal suspension�.

Horizontal reference Meaning Usual application

defined shifts in the horizontal direction as a factor of theparts contour (see exampleVStrip tool, Fig. 6/9).

1) See tab�Horizontal suspension�. The tab is only shown if at least one relative reference has beenselected.




The range, from which the relative reference value is calcu-lated, is defined by a vertical strip. This is related to the x-axis(y = 0). Within the range �Start in line� to �End in line� thesearch is now made for the first occurrence of the parts con-tour according to the specification �from left� or �from right�.The position found serves as the horizontal reference for thehorizontal position of the tool.

The width of the ROI tool joins on at this position in the direc-tion specified. Enter the width in the field �Width�.

Determining the vertical position and the width

The position of the tool in the vertical is determined by thedistance to a reference.

The height of the ROI tool joins on at this position in thedownward direction. Enter the height in the field �Height�.

Please noteExcept for the setting �absolute to bottom ...� (only withoperating systems ≥ 3.1) the definition of the position inthe vertical does not result from the distance to the heightY=0 (coordinate axis), but from the distance to a referencedefined in the tab �Vertical suspension�.

This has the advantage that the ROI tool can be placed rela-tive to the upper transition of the part. The ROI tool is there-fore less sensitive to fluctuations in height.



The vertical reference is calculated from an area of the uppertransition of the contour, similar to the features of the CTool.However, it can also be specified absolutely (only with operat-ing systems ≥ 3.1).

Vertical reference Meaning Usual application

relative to maximum ofvert. suspension

The upper limit of the tool refers to the maxi-mum of a value calculated from the contour 1)

e.g. when the suspension isto refer to a point of thepart.

relative to mean of vert.suspension

The upper limit of the tool refers to the aver-age of a value calculated from the contour 1)

e.g. when the suspension isto refer to a flat contoursection.

relative to minimum ofvert. suspension 2)

The upper limit of the tool refers to the mini-mum of a value calculated from the contour 1)

e.g. when the suspension isto refer to a recess.

relative, angle parallelto vert. suspension 2)

The upper limit of the tool refers to the equa-lizing line defined by the reference; the tool isplaced diagonally to the angle of the equaliz-ing line (upper and lower transitions)

e.g. when parts lie at vari-ous angles when received,but the ROI is not to be de-pendent on this.

absolute to bottom 2) The upper limit of the tool refers to the x-axis(y = 0).

e.g. when the tool is to beindependent of the partsposition.

1) See tab �Vertical suspension�. The tab is only shown if at least one relative reference has beenselected.




Determining the alignment (angle, only with operating sys-tems ≥ 3.1)

The upper and lower transitions of the tool can be placeddiagonally:

� Select the entry �relative, angle parallel to vert. suspen-sion� under �Vertical reference�. The tool is placed diag-onally to the angle of the equalizing line.

� Or enter the angle to the horizontal directly in the field�Angle�.Providing the vertical reference �Relative, angle parallelto vert. suspension� is defined, the angle specified herewill be added to the angle of the equalizing line.

No angle Alignment with entry of anangle

Alignment parallel to thesuspension

Fig. 6/18: Examples of the alignment (angle) of the ROI tool



Determining the vertical suspension

Providing a relative reference is used for the vertical position,it must be defined in the tab �Vertical suspension�.

The area from which the relative reference value is calculated,is defined by a left-hand and right-hand limit. These refer tothe start of the parts (left in CheckOpti) and/or to the end ofthe parts (right in CheckOpti).

The height of the ROI tool joins on at this position in thedownward direction.



Determining the horizontal suspension

Providing a relative reference is used for the horizontal posi-tion, it must be defined in the tab �Horizontal suspension�.

The range, from which the relative reference value is calcu-lated, is defined by a horizontal strip. This refers to the x-axis(y = 0) or to the vertical suspension.

Within the range �Begin in line� to �End in line� the search isnow made for the first occurrence of the parts contour ac-cording to the specification �from left� or �from right�.

The position found serves as the horizontal reference for thehorizontal position of the tool.



For the vertical position of the area �Begin in line� to �End inline� a further two references can be used:


absolute from bottom1)

The start and end of the vertical strip refer tothe x-axis (y = 0).


relative to vertical sus-pension 1)

The start and end of the vertical strip refer tothe vertical suspension. The area moves upor down with the vertical suspension 2).Please note that the start and end can alsobe negative values.

Providing no vertical suspension of the tool isdefined, the start and end of the vertical stripwill refer as with the setting �Absolute frombelow� to the x-axis (y = 0)

A reference to the verticalsuspension has the advan-tage that the position ofthe area (which is used fordetermining the horizontalsuspension), adapts itselfto the contour, e.g. whenthe suspension is to referto a recess.

1) Available for Checkboxes with operating system type Config, as from software version 3.1.2) See tab �Vertical suspension�. The tab is only shown if at least one relative reference has been

selected.



If an ROI has been selected, the area within the ROI will beshown in red.

The horizontal distance to the reference will be shown as ablue, horizontal bar.

The area of the transition of the contour, which is used forcalculating the upper reference value, is also marked in blue.

Starting from this area, the vertical distance will be shown asa blue vertical bar. If the vertical reference �Relative to maxi-mum of vert. suspension� is used, the bar will start at thepoint which has led to the maximum coordinate (highest pointin the area):

Fig. 6/21: ROI, horizontal reference �absolute from left�, vertical reference �Relative tomaximum of vert. suspension�



If the vertical reference �Relative to mean of vert. suspen-sion� is used, the bar will start in the centre of the area and inthe �Average� height.

Fig. 6/22: ROI, horizontal reference �from left�, vertical reference �relative, to mean ofvert. suspension�

Example:

A miniature plug connector is to be moved with the correctorientation to a components fitting installation. However, onlyorientation 1 may be used here, all further orientations are tobe returned to the conveyor system.

The part may be passed to the Checkbox in four orientations,whereby orientations 1 and 3 (or 2 and 4) are distinguishedonly by a small chamfer on the upper right-hand (or left-hand)corner of the part.



Good orientation 1 (target orientation) Good orientation 2

Good orientation 3 Good orientation 4

Fig. 6/23: Possible orientations

As orientation 1 is the �target orientation�, this must be dis-tinguished reliably from the other orientations, especiallyorientation 3. This is accomplished with a small ROI toolwhich examines the chamfer.

Fig. 6/25: Feature sequence of the ROI tool

The check of the reliability to separate the orientations in thewindow �Feature graph� shows a clear separation betweenorientation 1 (parts 1 to 10) and the remaining orientations(parts 11 to 37).



Example:

A parts-reversing station, which can reverse the parts accord-ing to the signals from the Checkbox, is fitted in the path fromthe Checkbox to the components fitting installation.

In order to separate further orientations reliably from eachother (orientation 2 from 3 and orientation 2 from 4), furthertools can be set up with CheckOpti.

This could be accomplished with an ROI tool with the ap-propriate settings, e.g. on the upper left-hand corner.

With this further tool, the feature sequence is as follows:

1 Orientation 1

2 Orientation 2

3 Orientation 3

4 Orientation 4

All orientations could therefore be separated from each otherjust with this tool.



6.5 Measuring tools

Various measuring tools are available with certain operatingsystems as from version ≥ 3.1 (software version of the Check-box). These tools ascertain the transition points between thebackground and the contour along one or two search lines.

For every two points selected, e.g. the distance from eachother or the angle of a line can be calculated with the twopoints to the horizontal, etc.

The selection of the points which belong together can be ac-complished with direct specification of the point number (withsingle measurement) or by the type of transition (with multi-measurement): background} parts contour or parts con-tour} background).

With the tools �Distance measurement (horizontal)�, �Multi-distance measurement (horizontal)�, �Distance measurement(vertical)� and �Counting�, measurement can be made eitherwith one search line (see Fig. 6/28) or with two search lines(see Fig. 6/29).

Two separate search lines are always required for the tools�Angle measurement� and �Multi-angle measurement�.

6.5.1 Position and suspension of the measuring tools

With all measuring tools, the search lines are defined in thetabs �Position� and �Vertical suspension�.

The size as well as the positions are entered in pixels.



Determining the horizontal reference and the width

The position of the search line in the horizontal is determinedby the distance to the start of the parts (from the left) or tothe end of the parts (from the right).

Select the reference of the distances under �Horizontal refer-ence�:

Horizontal reference Meaning Usual application

absolute, from left The left-hand limit of the tool refers tothe start of the parts

The contour section to be exam-ined lies left of the centre

absolute from right The right-hand limit of the tool refersto the end of the parts

The contour section to be exam-ined lies right of the centre

Please noteNo relative reference is available with the measuring tools.

The width of the search line joins on at this position in thedirection specified. Enter the width in the field �Width�.

Determining the vertical position and the height

The position of the first search line in the vertical is deter-mined by the distance to a reference.

The vertical position of the 2nd search line joins on at thisposition in the downward direction (if defined). Enter the dis-tance to the first search line in the field �Height�.

Please noteExcept for the setting �Absolutely from below ...� (onlyoperating system ≥ 3.1), the definition of the position in thevertical does not result from the distance to the height y =0 (coordinate axis), but from the distance to a referencedefined in the tab �suspension�.



This has the advantage that the search line can be placedrelative to the upper transition of the part. The measuringtools are therefore less sensitive to fluctuations in height.

The vertical position of the search lines is calculated from anarea on an transition of the contour, similar to the features ofthe CTool. However, it can also be specified absolutely (onlywith operating system ≥ 3.1).


relative to maximum ofvert. suspension

The vertical position of the search line refersto the maximum of a value calculated fromthe contour 1)

e.g. when the suspensionis to refer to a point of thepart.

relative to mean ofvert. suspension

The vertical position of the search line refersto the average of a value calculated from thecontour 1)

e.g. when the suspensionis to refer to a flat contoursection.

relative to minimum ofvert. suspension 2)

The vertical position of the search line refersto the minimum of a value calculated fromthe contour 1)

e.g. when the suspensionis to refer to a recess.

relative, angle parallelto vert. suspension 2)

The vertical position of the search line refersto the equalizing line defined by the refer-ence; the search lines are placed diagonallyto the angle of the equalizing line (upper andlower transitions)

e.g. when parts lie at vari-ous angles when received,but the measuring toolsare not to be dependent onthis.

absolute from bottom2)

The vertical position of the search line refersto the x-axis (y = 0)


1) See tab �Vertical suspension�2) Available for Checkboxes with operating system type Config, as from software version 3.1.



Determining the alignment (angle)

The search lines can also be placed diagonally (correspon-ding to the upper and lower transitions with the ROI tool, seesection 6.4):

� Select the entry �relative, angle parallel to suspension�under �Vertical reference�. The search lines are placeddiagonally to the angle of the equalizing line.

� Enter the angle to the horizontal in the field �Angle�.Providing the vertical reference �relative, angle parallel tosuspension� is defined, the angle specified here will beadded to the angle of the equalizing line.

Determining the vertical suspension

Providing a relative reference is used, it must be defined inthe tab �Vertical suspension�.

The area from which the relative reference value is calculated,is defined by a left-hand and right-hand limit. These refer tothe start of the parts (left in CheckOpti) and/or to the end ofthe parts (right in CheckOpti).

Possible exception:If e.g. a contour section to the left of the centre is to betested, but the manufacturing tolerances on the test part aremeasured from the right and are therefore usually less. In thiscase select �absolute from right� for both references, al-though the measuring tool lies left of the centre.

The distance to the first search line joins on at this position inthe downward direction.



If a measuring tool has been selected, the measuring vari-ables ascertained will be shown in red. With multi-tools theextremes searched will be shown in pink.

The search lines will be shown in green.

The area of the transition of the contour, which is used forcalculating the reference, the equalizing line and the dis-tances to the references are also shown in blue.

Help lines are shown in yellow.

Description of the combinations:

Combination Description

Addition (F1 + F2) The feature of the tool is derived from the addition of feature 1 andfeature 2.

Subtraction (F1 - F2) The feature of the tool is derived from the subtraction of feature 2from feature 1.

Multiplication (F1 * F2) The feature of the tool is derived from the multiplication of feature 1by feature 2.

Division (F1 / F2) The feature of the tool is derived from the division of feature 1 byfeature 2 (if F2 = 0, the result is also = 0).

Less-equal (F1 < = F2) Logical operation: The feature has the value 1 if F1 is smaller orequal to F2. The feature has the value 0 if F1 is greater than F2.

Greater (F1 > F2) Logical operation: The feature has the value 1 if F1 is greater thanF2. The feature has the value 0 if F1 is smaller or equal to F2.

Examples:

Example 1 A certain angle on a part is to be checked. The part can bepresented during the parts test in various alignments. Bylinking two suitable angles, you can compensate the variousalignments when measuring the relevant angle.

Example 2 Any desired conveyor can be used with the Compact Check-box. If the parts are tested at different speeds, a direct com-parison of the actual part lengths is not possible.You can compensate for this with a feature linking of type�Division� of CG_co_x (centre of gravity coordinate in X-direc-tion) related to the Length _x (length of part).



6.7 Externally calculated feature tool (sensor)

The tool �Externally calculated feature� enables the accept-ance of a value ascertained by an external sensor as an addi-tional feature.

This function is only available with special variants of theCheckbox.

A.2 Example

For the following example you will find an appropriate projectin the sub-directory �Demo� of the program directory ofCheckOpti.

Further information can be found in section 6.1, �Descriptionof the configuration tools�.

All the examples refer to a Checkbox with operating system�Config ...�.

Adapting features for the test

The parts test can be influenced by the user. This is usuallyaccomplished when the user sets the tolerance on the Check-box. The tolerance range of all the features is thereby modi-fied by the same degree.

However, in many cases it is an advantage if the features areadapted manually. The test of the features can be influencedin the following ways:

1. With the tolerance factor, you can specify to what extentthe tolerance setting of the Checkbox has an effect on theindividual feature.

2. By switching off the feature, you can specify that the fea-ture is not to be tested at all.

3. As a special case, you can enter the tolerance range man-ually (i.e. the values do not depend on the values ascer-tained during the teach procedure).

To do this, select the appropriate feature in the window�Teach-Data� or �Part contour�.



With a double click on the name of the relevant feature, youcan open the window �Feature properties�.

Fig. A/1: Window �Feature properties� � register card �Settings�

The settings made are shown in the window �Teach-Data�(see section 3.2.2).



The feature can be configured as follows:

Methods Entry Description Typical application

Deactivatefeature

Activate option�disable feature�

With this setting, the featurewill be completely deactivatedand therefore not taken into ac-count during teaching and test-ing.

Features are switched off ifthey have a negative influ-ence on the test (e.g. if cor-rect good parts are some-times classified as badparts as a result of this fea-ture).

Enter toler-ance factor

The tolerance fac-tor is entered inthe appropriatefield.

The standard setting of the tol-erance factor is 1.0, i.e. the tol-erance set on the Checkboxflows unmodified into the testof this feature.If e.g. 0.1 is entered with fea-ture �Length_x� and if 1.0 is en-tered with feature �Height_y�with a tolerance of 5%, 0.5%will be specified for length and5% for height.

The tolerance factor isusually modified when indi-vidual features are of vary-ing importance for the test,i.e. if the specification oftolerances is critical for theassessment of quality withindividual features, or ifother features are allowedto be extremely widely scat-tered.

Enter toler-ance rangemanually

Activate the checkbox �Manual edit-ing activated�

With this setting you can entermanually the desired permittedvalue ranges in the fields in-tended for this purpose.The options �Influence of teachprocess on the Checkbox ...�defines the reaction of theCheckbox:� �no change of manual edit-

ing (protected/locked)�:the manually entered valueswill not be overwritten duringa new teach procedure.

� �overwrite of manual editing(not protected/not locked)�:the manually entered valueswill be adapted to the newpart during a new teach pro-cedure.

It is sensible to enter thevalue range of a featuremanually if, e.g. the ap-proximate scatter of theproduction is known, butnot all the representativesample parts are available.The manually entered va-lues will be subject to theusual tolerance (set on theCheckbox) during the test.



Example of metal springs

While being passed to an automatic assembly machine,springs have to be tested to make sure that they have thecorrect number of turns, i.e. that their height is correct. Anadditional check must be made to see if the springs pass theCheckOpti individually.

The spring is always conveyed in the upright position, so theorientation does not have to be checked.

Fig. A/2: Contour images of the springs

Good springs can appear on the belt in all possible positions.It is therefore difficult to teach the complete spectrum of thepossible positions of the springs.



Checking the height Bad springs can be recognized by their height.

As this is the decisive feature for the test, the deviation mustbe less than that permitted for the other features. The toler-ance range of the feature should therefore be reduced.

With the setting 0.5 of the tolerance factor for the feature�Height_y� and with a tolerance of 5% set on the Checkbox,the height of the springs will be tolerated as follows:

5 % x 0.5 = 2.5 %

All other features have the standard setting 1.0 for the toler-ance factor and are therefore tolerated with 5 %.

1 Tolerance factor

Fig. A/3: Feature properties - reduce tolerance



In this way, springs with the incorrect height will be reliablydetected without other irrelevant deviations being taken intoaccount.

Fig. A/4: Bad springs with incorrect height

Variation of positions As not all positions can be demonstrated, it may happen thatgood parts are sometimes incorrectly recognized as badparts due to the features �Feat_11� and �Feat_12�.

In order to prevent this, these features have been switchedoff in the example (option �Disable feature�).

The �disturbing� features are not therefore taken into ac-count during the parts test. Features which have beenswitched off are marked with a �D� (deactivated) in the win-dow �Teach-Data�.

As a result of the adaptions carried out, the test parts in theexample are now recognized correctly.
