As people's demands for comfort, economy and safety keep rising, the types of electronic products in cars are also increasing, and the complexity of car wiring is also growing. The failure rate of wiring also increases accordingly. This requires improving the reliability and durability of wiring, etc. Many people are interested in the process and production of car wiring. Here, we will briefly describe the knowledge about the process and production of car wiring. You only need to spend a few minutes reading and you can get a general understanding.
After the two-dimensional product drawings of the automotive wiring harness were completed, the production process of the wiring harness needs to be arranged. The process is closely related to production and therefore, Shuanshang will analyze the production and process of the automotive wiring harness together.
The first workstation in wire harness production is the wire cutting process. The accuracy of this process directly affects the overall production schedule. Any errors, especially if the wire cutting length is too short, will lead to rework at all subsequent workstations, consuming a lot of time and effort and negatively impacting production efficiency. Therefore, when formulating the wire cutting process, it is essential to reasonably determine the wire cutting length and stripping length according to the requirements of the drawings.
The second workstation after the line opening is the pressing process. According to the terminal type specified in the drawing, the pressing parameters are determined, the operation manual for pressing is made, and for those with special requirements, they need to be noted in the process document and the operators need to be trained. For example: Some wires need to pass through the sheath before they can be pressed. It requires pre-installing the wire first, then returning from the pre-installation workstation and then pressing; there are piercing-type presses that use special pressing tools, and this pressing method has good electrical contact performance.
Next comes the pre-installation process. The first step is to compile a pre-installation process operation manual. To enhance the overall assembly efficiency, complex wiring harnesses need to be set up with pre-installation stations. The rationality of the pre-installation process directly affects the efficiency of the overall assembly and reflects the technical proficiency of the process personnel. If the pre-installation assembly is insufficient or the wiring path is unreasonable, it will increase the workload of the overall assembly personnel and slow down the speed of the assembly line. Therefore, process personnel should frequently be on-site to constantly summarize.
The final step is the final assembly process. It is possible to design the assembly platform according to the design of the product development department, design the tooling equipment, material box specifications and sizes, and affix the serial numbers of all assembly covers and accessories on the material boxes to improve assembly efficiency. Compile the assembly contents and requirements for each workstation, balance the entire assembly workstation to prevent any workstation from having an excessive workload, and prevent the entire assembly line from slowing down due to this. To achieve workstation balance, the process personnel must be familiar with each operation and measure the working hours on-site, and adjust the assembly process at any time.
In addition, the wiring process also includes compiling the material consumption quota table, labor hour calculation, and worker training. Due to the relatively low technical content, these details will not be elaborated further. In summary, the electronic technology content and quality of automotive wiring in the vehicle have gradually become an important indicator for evaluating the performance of automobiles. Automobile manufacturers should pay particular attention to the selection of wiring, and it is also necessary to understand the process and production of automotive wiring.
