1. IPD Technical Conference February 19 th 2008 Automotive Chain Inspection

2. Application  Provide verification that all chain links are present before guide installation.  After installation of guide, provide verification of guide presence and color.  Provide verification that rivet has been struck.  Various thickness chains need to be inspected on the same line  Various lengths of chain need to be inspected on the same line

3. Requirements  Link inspection  Distance from camera face to product cannot exceed 4”  Guide Presence/Color  Distance from camera face to product cannot exceed 6”  Colored guide appears every “x” number of inspections depending on chain produced  Rivet inspection  Distance from camera face to product cannot exceed 6”  Every “x” number of inspections there is an intentionally missed rivet for the hook up joint of the chain

4. Requirements  All inspections must utilize front lighting  All inspections can utilize the same trigger as the chain is being indexed  Vision system must be able to communicate the result of each inspection independently using digital I/O  Vision system must be able to provide an additional output to be used as a heartbeat to verify that an image has been acquired and that the image has been processed

5. Missing Link Lighting Area Array vs. DOAL

6. Missing Link  Hardware  TM2 camera  50mm DOAL  9mm lens  Software  Count tool  Reject if we see any large areas of dark

7. Rivet Inspection Good rivet

8. Rivet Inspection Missed Rivet

9. Rivet Inspection  Hardware  TM2 camera  25mm lens  70mm ring light  Software  Four intensity tools  Reject if any tools average intensity is darker than it should be

10. Guide Presence/Color Colored Guide

11. Guide Presence/Color Non-colored guide

12. Guide Presence/Color  Hardware  TM2 camera  25mm lens  70mm ring light  Software  Arc Tool to verify guide presence  Intensity tool to determine if guide is colored or not

13. Communication

14. Heartbeat

18. Automotive Chain Inspection  We quoted a VA40E-03-C53-0 with all necessary lighting & lenses.  The local Cognex/DVT distributor was also given an opportunity to quote against us.  The local Cognex/DVT distributor told the customer that they could not compete against us on a three camera system  We won the job!  It was determined that the customer also needed a single camera system located downstream of the VA40E that they purchased.  The customer purchased a VA15 to do the job without looking at anyone else.

19. Single Camera Inspection  After chain is assembled, the chain is placed under tension and driven with two sprockets.  The chain is inspected to be sure that all of the components have been assembled onto the chain.

20. Single Camera Inspection  Hardware  TM2 camera  16mm lens  50mmx50mm backlight  Software  Count tool  Reject if we do not have the right number of light areas in either one of the ROIs
