TCO(THERMAL CUT OFF) AUTOMATIC WELDING DEVICE

摘要

According to the present invention, an automatic welding device for a thermal cutoff (TCO) enables accurate laser welding by mounting a TCO temperature fuse applied to a battery protection circuit of a mobile device and a conductive thin film on a welding jig member in parallel and then pressing an overlapped portion between the conductive thin film and the temperature fuse terminal using a pressing member before a laser welding operation while moving the TCO temperature fuse and the conductive thin film using a transfer belt circulating on a caterpillar track. Also, the present invention determines the mounting and overlap insertion of the temperature fuse and the conductive thin film through a contact or noncontact type insertion inspecting member installed in a transfer belt moving path before the welding operation, determines welding defects by comparing a welded portion of the TCO photographed after the welding operation with a basic image, and measures the resistance value of the temperature fuse by being in contact with both ends of the conductive thin film using a function inspection member Thus, the present invention enables the mass production of the high quality TCOs by guaranteeing the stable performance and reliability of the temperature fuse of the TCO.
