ILLUMINATING DEVICE IN CURVED SURFACE PROPERTY INSPECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an illuminating device in a curved surface property inspection apparatus that can secure a lower illuminating angle necessary for improvement of inspection accuracy even if an illuminating device is made small-sized.;SOLUTION: The inspection apparatus 10 includes a main illuminating part 11 arranged over the surface of an assembled board 110 carried in with a predetermined clearance H for illuminating the surface of the board 110 by a plurality of color lights, each light having a different illuminating angle from each other, a color camera 12 for separately imaging each color light reflected off the surface of the board 110 which the color lights illuminate, and a compensatory illuminating part 13 for illuminating the surface of the board 110 by one of the color lights from a side direction of the board 110 at a lower illuminating angle than that of the main illuminating part 11.;COPYRIGHT: (C)2002,JPO
