For waterproof plugs that are similar or close in color, size, and shape, manual work is performed at different stations through process arrangement, or machine operation is performed through waterproof plugs; each waterproof plug storage container is marked with a material number, description, picture, etc. The logo can be effectively identified.
The kanban information, wire information, and product item information of each bundle of semi-finished wire labels are complete and clear, and can effectively prevent the use of kanban wires from errors. The semi-finished wires of the same kanban are stored in buffer racks, turnover cars, and turnover boxes, and the labels are complete and easy to identify, which can also effectively prevent the wrong use of kanban wires. In the wire crimping (welding) station, the most manufacturing errors are the wrong number of wires on the left and right sides or the wrong use of kanban. Therefore, in the process design, according to the closing line kanban operation card, two stations are assigned to carry out the binding operation before the closing line crimping, and the semi-finished product after the binding operation has a unique binding semi-finished product identification card. Use error-proof tooling to design wire-binding wire isolation grooves or fixtures on the wire-binding station workbench, effectively prevent wire-binding operation errors, and prevent operation errors such as multi-tying, missing tying, and wrong tying.
