The error-proof design of the final assembly process card of the car wiring harness assembly line should follow the following principles:
● The wiring order of the pre-installed semi-finished products on the assembly board should be laid out first, the fuse box, ECU, the main sheath with more holes, and the branch sheath semi-finished products that need to wear terminals on the assembly line;
● The wiring of the sheath on the wiring board should be balanced, and the wiring personnel can work together to work at both ends of the assembly board, and the working time for each hanging station to wear terminals and buckle and self-lock should be balanced;
● The operation of installing wire harness sheath self-locking, buckle self-locking, and sheathing shell should be indicated on the assembly line process card, and the operation should be completed by the line hanging and threading personnel;
● The scope of work of bandaging personnel should be in one area as much as possible, and try to arrange regional branches wrapped with the same tape to reduce the frequency of tape replacement. The order of choreography should be branched first, followed by the trunk, and finally centralized to avoid cross-operation;
● Similar clips, buckles, and cable ties are installed by personnel with different designs, and the shapes of the clips, buckles, and cable ties installed by each operator must be greatly different to avoid wrong installation.
