Nowadays, with the continuous improvement of people's requirements for life, there are more and more kinds of electronic products in cars, Automotive wiring harnessWith the increasing complexity, the failure rate of automobile wiring harness also increases correspondingly. This requires improving the reliability and durability of automobile wiring harness. Many people don't know much about the production process of automobile wire harness. Let's talk about the basic situation of the production process of automobile wire harness.

After the product drawing of automobile wire harness is drawn, the production process of wire harness should be arranged. The process serves the production, and the starting process of harness production is the opening process. The accuracy of the opening process is directly related to the production progress. In case of error, if the size is too short, it will lead to rework at each station, waste time and energy, and affect production efficiency. Therefore, at the beginning of the line opening process, the accuracy must be reasonably controlled according to the drawing requirements.

Next is the crimping process. According to the terminal type required by the drawing, determine crimping parameters, formulate crimping operation procedures, and indicate special requirements on the process documents, and train operators. There are piercing crimping with special crimping tools. This crimping method has good electrical contact performance.

Then comes the pre-assembly process. The pre-assembly process operation manual shall be prepared first. In order to improve the assembly efficiency, a pre-assembly station should be set for complex harnesses. Whether the preassembly process is reasonable will affect the efficiency of the final assembly and also reflect the technical level of a technician. If there are few preassembled parts or the assembly route is unreasonable, the workload of the general assembly personnel will be increased and the speed of the assembly line will be slowed down. Therefore, the process personnel should always stay on the site and constantly summarize.

Finally, the final assembly process. According to the assembly table developed and designed, design the specifications and dimensions of tooling equipment and material box, and paste all assembly protectors and numbers on the material box to improve the assembly efficiency. Formulate the assembly contents and requirements of each station, balance the entire assembly station, and prevent excessive workload from dragging down the speed of the entire assembly line. In order to achieve the balance of working position, technicians must be familiar with each operation, calculate the working time on site, and adjust the assembly process according to the site conditions.

In addition, the automobile wiring harness process also includes the preparation of material consumption quota table, working hour calculation, worker training, etc. In a word, the quality of automobile wiring harness has gradually become an index to evaluate automobile performance. Automobile manufacturers should pay special attention when selecting wire harnesses. It is necessary to understand the process and production of automobile wire harnesses.
