1. INDUSTRIAL MACHINE VISION


1. Industrial Machine Vision: Targets

• surface detection • quality control • identification • Process control/-handling • high speed process analysis

• tailor-made individual and modular systems


2. BORE HOLE INSPECTION

Industrielle Bildverarbeitung


2. Bore Hole Inspection

• patented Bore Hole Inspection system (BLI) to detect bore holes and blind holes on – thread completeness – features – remnants e.g. chips or foreign parts

• no endoscope camera required • modular or stand-alone: can be implemented into

existing systems • detection of features in a range of 200 µm



• detection of – surface flaws (scratches, adhesions), – control if remaining chips exist – control if all elements of a part are complete

• main field of application is thread control

– nuts with complete threads – thread intakes and outtakes – no remaining chips

chip detection/ foreign particles detection of production flaws, chips and foreign particles in bore holes and blind holes; sizes from 2.5 - 40 mm


cross holes detection of cross holes in bore holes and blind holes;Ø: depth up to 1:3


inspection of internal threads detection of flaws in internal threads of bore holes and blind holes; sizes from 2.5 - 40 mm


parameters detection if features are present (e.g. rings or gaskets) at the inside of of the fitting; sizes from 2.5 - 40 mm


casting defects detection of casting defects


chip detection/ foreign particles chip detection, foreign particles and production flaws in nuts; sizes 2.5 – 40 mm

2.1 HIGH-END BLI


2.1 Bore Hole Inspection: High-End BLI

• special entocentric lens • special lighting solution

• inspection security at a diameter/ depth ratio of 1:3

(Dmax = 40 mm) • cycle time: < 0.5s • minimum bore hole diamter: 3 mm • focal length: f=6,5 mm • camera resolution: 1.3 megapixels


2.1 Bore Hole Inspection: Entocentric Lens


2.1 Bore Hole Inspection: Ento- / Telecentric

• parts with varying distances appear larger

• the image scale is different for every working distance

• within the telecentric range (z-direction) parts appear equally large

• the telecentric range is typically larger than the depth of field

Entocentric lens Telecentric lens


2.1 Bore Hole Inspection: lighting concept

optical path with light guide and Iris-diaphragm



• light guide • to guide light into the bore hole (opening should equal the size of the bore

hole)



• iris diaphragm • to avoid reflection of high glossy parts



• without adapters • to inspect small parts with the help of extension tubes (small working

distance required)



• lighting plate (backlight) • for larger parts with bore holes



• incident light • backlight


2.1 Bore Hole Inspection: equipment options

• BLI-hardware only, viewer software • BLI-hardware only, viewer software, PC workstation, desk • BLI-hardware, PC workstation with Matrox Imaging Library and testing

algorithm for a single part • additional testing algorithms (charged separately)
