Evaluation method of surface condition of inspection object, evaluation device, control method of evaluation device and control program of evaluation device

摘要

A point on the surface of the accepted product is measured in advance by a color sensor (32) in a non-contact manner, a passing standard value is set based on the output value, and then a point on the surface of the inspection object having the same design specifications as the accepted product is measured. The color sensor (32) is used for non-contact measurement, and the output value is compared with the acceptance reference value to determine pass / fail. Since the pass / fail judgment can be made without contacting the inspection object in this way, it can be applied to a high-speed production line.
