With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products on the automobile are also increasing. The automobile wiring harness is becoming more and more complex, and the failure rate of the wiring harness is also increasing accordingly. This requires improving the reliability and durability of the wire harness. Many people are interested in the process and production of the automobile wire harness. Here, I will give a brief description of the knowledge of the process and production of the automobile wire harness. You only need to spend a few minutes to read it.
After the two-dimensional product drawing of automobile wire harness is published, the production process of the wire harness shall be arranged. The process serves the production and the two are inseparable. Therefore, the author combines the production and the process of the automobile wire harness and analyzes them together.
The first station of wire harness production is the opening process. The accuracy of the opening process is directly related to the whole production progress. Once there is an error, especially the opening size is too short, it will lead to rework of all stations, which is time-consuming and laborious and will affect the production efficiency. Therefore, it is necessary to reasonably determine the wire opening size and stripping head size according to the requirements of the drawings when preparing the wire opening process.
The second station after the line is opened is the crimping process. The crimping parameters are determined according to the terminal types required in the drawings, and the crimping operation instructions are prepared. For special requirements, the operators need to be noted on the process documents and trained. For example, some wires need to pass through the sheath before crimping. It needs to pre assemble the wires and then return 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 of all, prepare the pre assembly process operation manual. In order to improve the assembly efficiency, complex wire harnesses must be equipped with pre assembly stations. The rationality of the pre assembly process directly affects the efficiency of the general assembly and reflects the technical level of a technician. If the preassembled parts are less assembled or the assembled wire path 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 to constantly summarize.
The last step is the final assembly process. Be able to compile the assembly platen designed by the product development department, design the specifications and dimensions of tooling equipment and material boxes, and paste the numbers of all assembly sheaths and accessories on the material boxes 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 station balance, the process personnel must be familiar with each operation, calculate the working hours on site, and adjust the assembly process at any time.
