ELECTRODE INSPECTION DEVICE FOR SPOT WELDING

WIPO Patent Application WO/2011/052308

A1

Disclosed is an electrode inspection device that can accurately measure the diameter of an electrode tip without reducing the operating rate of a manufacturing line, and that is especially useful when a welding gun with a small electrode interval is used. CCD cameras (91) for photographing electrode tips held in a welding gun are installed in the inspection device body (6). The inspection device body (6) is provided with measurement reference sections (7) in which fixing holes (72a) are formed that fix electrode tips, and a mirror (8) disposed at an incline to the electrodes and distanced from the fixing holes (72a) on the side of the measurement reference section (7) opposite to the electrodes, and the CCD cameras (91) are disposed at a distance from the sides of the aforementioned mirror (8) so as to frontally photograph the electrode tips reflected by said mirror (8).
