What are several kinds of automobile wiring harness process？

2022-12-27
1. Open wire process. The accuracy of the open wire process is directly related to the entire production schedule. Once there is an error, especially the short size of the open wire, it will lead to rework at all stations, which takes time and effort to affect production efficiency. Therefore, in the preparation of the open wire process, it is necessary to determine the open wire size and stripping head size reasonably according to the requirements of the drawings. 
2. Crimping process. Determine crimple parameters according to the terminal type required by the drawing, make crimple operation instruction, indicate on the process documents and train operators for special requirements. For example: some wires need to pass through the sheath before crisping, it needs to pre-install the wire and then return from the pre-installed position and crisping; There is also a puncture type of crisping with a special crisping tool, this crisping method has good electrical contact performance.
3. Preassembly process. First of all, the pre-assembly process operation manual should be prepared. In order to improve the efficiency of the final assembly, the complex wiring harnesses should be set up pre-assembly stations. Whether the pre-assembly process is reasonable or not directly affects the efficiency of the total assembly and reflects the technical level of a technical personnel. If the preassembled part is less assembled or the assembled wire path is not appropriate, the workload of the total assembly personnel will be increased, and the speed of the assembly wire will be slowed down, so the technical personnel will often stay at the site to summarize. 

4. Assembly process. Be able to design the specifications and dimensions of tooling equipment and material box according to the assembly table designed by product development department, design the size of tooling equipment, material box and attach the numbers of all assembly jackets and accessories to the material box to improve assembly efficiency. Prepare 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 wire is pulled down. To achieve the balance of work stations, the technical personnel must be familiar with each operation and calculate the working hours on the spot, and adjust the assembly process at any time.
