With the continuous improvement of people's requirements for comfort, economy and safety, the kinds of electronic products on the automobile are also increasing, the automobile wiring harness is more and more complex, and the failure rate of wiring harness is also increasing accordingly. This requires to improve the reliability and durability of wire harness. Many people are interested in the process and production of automotive wiring harnesses. Here, a brief description of automotive wiring harness technology and production knowledge. It only takes you a few minutes to get a sense of it.

After the 2d product drawing of automobile wiring harness is produced, the production process of wiring harness needs to be arranged. This process serves production. Therefore, the production and process of Shanghai Huifeng electronic automobile wiring harness are analyzed.
The first station in harness production is the unwiring process. The accuracy of the opening process is directly related to the overall production schedule. Once the error occurs, especially the short size of the opening line, it will lead to rework of all stations, time-consuming and laborious, affecting production efficiency. Therefore, in the preparation of the opening process, according to the requirements of the drawing must be reasonable to determine the size of the opening and stripping head.
The second stop after the opening is the crimping process. The crimping parameters shall be determined according to the terminal type required in the drawing, and the crimping operation manual shall be formulated. For special requirements, it shall be indicated in the process documents and operators shall be trained. For example, some wires need to pass through a sheath before they can be crimped. They need to be pre-wired, returned from the pre-wired station, and then crimped; There are also special crimping tools for piercing crimping, with good electrical contact performance.
Then there is the pre-installation process. First, the pre-installation process operation manual should be prepared. In order to improve assembly efficiency, a complex wire harness preassembly station should be set up. The rationality of the preassembly process directly affects the assembly efficiency and reflects the technical level of the process personnel. If the preassembled part is less or the assembly line path is unreasonable, it will increase the workload of assemblers and slow down the speed of the assembly line, so the process personnel should often stay on site to summarize.
The final step is the assembly process. According to the specifications and dimensions of assembly board, tooling equipment and material box designed by product development department, and the serial numbers of all assembly jackets and accessories can be affixed to the material box to improve assembly efficiency. Compile assembly contents and requirements of each station, balance the whole assembly station, prevent excessive workload and reduce the speed of the whole assembly line. In order to balance the site, the technician must be familiar with each operation, calculate the working time on site and adjust the assembly process at any time.
In addition, the wiring harness process also includes the preparation of material consumption quota table, man-hour calculation, worker training, etc., because the technical content value is not high, not detailed. In short, the electronic technology content and quality of automobile wiring harness have gradually become an important index for evaluating automobile performance. Automobile manufacturers should pay special attention to the selection of wiring harnesses, and it is necessary to understand the process and production of automotive wiring harnesses.
