Detection of Second Top Coat Errors for Two Tones

This enables the prevention of vehicles without coating. In recent years, there has been an increase in models with two-tone body color. Vehicles with two-tone color realize two tones by utilizing two cycles of the top coating process, but there are cases where they flow to the next process after only one top coating. Using a vision system for detection in the inspection process before sending the piece on to the assembly process enables the prevention of on flow.
