What kinds of processes are available for automotive wiring harnesses

1、 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. Therefore, in the preparation of the wire opening process, the wire opening size and stripping size must be reasonably determined according to the requirements of the drawings. 2、 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, it is necessary to indicate them in the process documents and train the operators. For example, some wires need to pass through the sheath before crimping, and they need to be pre-assembled and returned from the pre-assembly station before crimping; there is also a special crimping tool for piercing crimping, which has good electrical contact performance. 3、 pre-assembly process. First of all, the pre-assembly process operation instructions should be prepared. In order to improve the efficiency of final assembly, pre-assembly stations should be set for complex wiring harnesses. Whether the pre-assembly process is reasonable or not directly affects the efficiency of final assembly and also reflects the technical level of a technician. 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 and slow down the speed of the assembly line, so the process personnel should often stay on site and constantly summarize. 4、 assembly process. Be able to edit 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. Compile the assembly content and requirements of each station, balance the whole assembly station to prevent the situation that the workload is too large and the speed of the whole assembly line is pulled down. To achieve station balance, technicians must be familiar with each operation and calculate the working hours on site, and adjust the assembly process at any time.
