This evaluation is broken down into two different areas (1) Inspection part to ensure the black tabs are bent in place (2) Inspection to ensure the brass clips are present. Pattern tools, blob tools and brightness tools are used to complete the inspection. The angle of the part is critical for the application. The part must be presented perfectly flat to the camera. This allows us to create the needed reflections utilized for the inspection. Two wide angle Red linear lights are needed to evenly illuminate the part. Red is needed to create contrast between the black tabs and the black background. Two camera are needed for the inspection. This is due to more resolution needed to pick out the black tabs. We also need to utilize two different camera setups. One camera is optimized for the brass clips and the other is optimized for the Black tabs.
