In the wire crimping (welding) station, the most common manufacturing errors are the wrong number of wires on the left and right sides or the wrong use of the kanban. Therefore, in the process design, according to the wire bonding kanban work card, two stations are allocated for the wire bonding operation before the wire bonding and crimping. Use error-proofing tooling to design wire-binding wire isolation grooves or fixtures on the workbench of the wire-binding station, which can effectively prevent errors in wire-binding operations, and prevent operation errors such as multiple ties, missing ties, and wrong ties.
