Understand the process flow of wire harness production and the importance of harness selection

The first station of wire harness production is the wire opening process. The accuracy of the opening process is directly related to the entire production schedule, once the error occurs, especially the opening size is too short, it will lead to the rework of all stations, which is time-consuming and laborious and affects the production efficiency. The second station after wire opening is the crimping process. The crimping parameters shall be determined according to the terminal type required in the drawing, and the crimping operation instructions shall be prepared. For special requirements, the process documents shall be indicated and the operators shall be trained. The next step is the pre-assembly process. First of all, the pre-assembly process operation instructions should be prepared. In order to improve the efficiency of final assembly, complex wiring harnesses should be equipped with pre-assembly stations. If the pre-assembly part is assembled too little or the assembly wire path is unreasonable, it will increase the workload of the general assembly personnel. The final step is the final assembly process. According to the assembly platen designed by the product development department, design the specifications and dimensions of tooling equipment and material boxes, and paste the numbers of all assembly sheaths and accessories on the material boxes to improve the assembly efficiency. The electronic technology content and quality of electric vehicle wiring harness in the vehicle have gradually become an important index to evaluate the performance of electric vehicles. Electric vehicle manufacturers also attach great importance to the choice of wiring harness, so they must understand the process and production of electric vehicle wiring harness.
