ELECTRODE INSPECTION APPARATUS FOR SPOT WELDING

摘要

A small camera module is simply assembled in a short time, while reducing displacement of a camera relative to the first and second frames. Specifically, the camera module is assembled by bending a pair of clips to engage engaging portions of the clips with engaging recesses of the first and second frames to fix the first frame, camera holders, and the second frame, with the first and second frames located at both sides of each camera holder with a housing recess facing outward, and using resilient force of each of the clips to press the camera with a projection of the clip.

主权项

1. An electrode inspection apparatus for spot welding comprising:
measuring reference plates, each having an electrode fixing hole for inserting and fixing a tip of an electrode for spot welding; and a camera module, wherein the camera module includes a mirror configured to reflect a tip surface of the electrode, a module body including first and second frames located at both ends of the mirror, a camera located at each side of the mirror between the first and second frames, and configured to capture the tip surface of the electrode reflected by the mirror, a camera holder having a housing recess for housing the camera, and a pair of flexible band-like clips, the camera module is assembled by bending the both clips to engage ends of the both clips with end edges of the first and second frames to fix the first frame, the camera holder, and the second frame, with the first and second frames located at both sides of the camera holder with an opening of the housing recess facing outward, and using resilient force of each of the clips to press the camera in a middle of the clip, and the tip of the electrode is inserted into and fixed to the electrode fixing hole, with each of the measuring reference plates attached to the camera module such that the electrode fixing hole corresponds to the mirror, and the camera captures the tip surface of the electrode via the mirror to determine whether or not the tip surface of the electrode is usable.
