SPOT-WELDING ELECTRODE INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/075246
Kind Code:
A1
Abstract:
Provided is a spot-welding electrode inspection device that can be installed in a narrow space around an industrial robot, and that has high heat-dissipating properties making it less likely to adversely affect a control substrate during continuous use. The spot-welding electrode inspection device is provided with: a camera unit 2 including a camera body 7 for taking an image of a tip-end of a spot-welding electrode 10 having a welding gun G attached thereto; a control unit 3 for controlling the camera unit 2; and a camera cable 4 connecting the camera unit 2 and the control unit. The control unit 3 is provided with: a control substrate 32 for processing the image taken by the camera body 7 and determining the state of the electrode 10 by comparing a processing result of the image with a setting value which is set in advance; and a metal casing 31 housing the control substrate 32. The casing 31 is attached to a base 11 made of metal material.
