The problem: cracked or bent tabs upon installation of a Lexan 141 lens in to an ABS piece that causes rattles or vibrations for the customer. Need to be able to detect this condition and contain the part.

Defect:



Lens:



ABS Piece:



My first thought was mount a camera above the workstation and direct light in to the lens. Then use a camera to detect if the legs are bent. Below is an example.



While the image is clear and the contrast is good, I doubt detection in this manner would last long due to part variance and slight changes in operator part placement.

Anyone have another detection method I can try?
