With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products on cars will also increase,Automotive wiring harnessThe failure rate of increasingly complex harness in is also increasing correspondingly. This requires improving the reliability and durability of the harness. Many people are interested in the process and production of automobile harness. Here, make a simple description of the process and production knowledge of automobile wiring harness. You can get a general idea by reading it in a few minutes.

After the two-dimensional product drawing of automobile harness is released, it is necessary to arrange the harness production process, which is closely related to service production. Therefore, the production and process of automobile wire harness are analyzed together.


The first station of automobile wire harness production is the wire opening process. The accuracy of the line opening process is directly related to the overall production progress. Once there is an error, especially the short line opening size, it will cause rework at each station, which will take time and effort, and affect the production efficiency. Therefore, during the preparation of the wire opening process, the wire opening size and wire stripping size of the wire should be reasonably determined according to the requirements of the drawing.

The second station after the wire is opened is the crimping process. The crimping parameters shall be determined according to the terminal type required by the drawing, and the crimping operation instructions shall be prepared. For the needs with special requirements, it shall be noted in the process documents and the operators shall be trained. For example, some wires need to pass through the sheath before crimping. Before crimping, they need to be pre-assembled and then returned from the pre-assembly station before crimping; There are also special crimping tools for piercing crimping, which has good electrical contact performance.

Then comes the pre-assembly process. First, prepare the pre-assembly process operation instructions. In order to improve the assembly efficiency, complex harnesses should be equipped with pre-assembly stations. Whether the pre-assembly process is reasonable or not will directly affect the efficiency of the overall assembly, reflecting the technical level of a technician. If there are too few pre-assembled parts or the assembly wire path is unreasonable, it will increase the workload of the total assembly personnel and slow down the speed of the assembly line, so the process personnel should stay on the site and keep summarizing.

The final step is the final assembly process. Be able to design the specification and size of tooling equipment and material box according to the assembly platform designed by the product development department, and paste the number of all assembly jackets and accessories on the material box to improve the assembly efficiency. Prepare the assembly contents and requirements of each station, balance the whole assembly station, and prevent the situation that the workload is too large and the speed of the whole assembly line is reduced. To achieve the balance of work stations, the process personnel must be familiar with each operation, measure the working hours on site, and adjust the assembly process at any time.

In addition, the process of automobile wiring harness also includes the preparation of material consumption quota list, man-hour calculation, worker training, etc. Because the technical content is not high, we won't talk about it in detail. In short, the automotive electronic technology content and quality of automotive wiring harness has gradually become an important indicator to evaluate the performance of automobiles. Automobile manufacturers should pay special attention to the selection of automobile harnesses. It is also necessary to understand the process and production of automobile harnesses.
