With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products on automobiles are also increasing, and the failure rate of more and more complex wiring harnesses is also increasing accordingly. This requires improving the reliability and durability of wiring harness. Many people are interested in the process and production of automobile wiring harness. Here is a brief description of the process and production of automobile wiring harness. It only takes you a few minutes to read, and you can get a general understanding.
After the two-dimensional product drawings of automobile wiring harness come out, the production process of the wiring harness should be arranged. The process serves the production closely. Therefore, the author combines the production of automobile wiring harness with the process.
The first station in harness production is the opening process. The accuracy of the opening process is directly related to the overall production schedule. Once errors occur, especially the opening size is too short, it will lead to the rework of all stations, which will take time and effort to affect the production efficiency. Therefore, in compiling the opening process, it is necessary to determine the opening size and stripping size of the conductor reasonably according to the requirements of the drawings.
The second position after the opening of the line is the crimping process. The crimping parameters are determined according to the terminal types required in the drawings. The crimping operation instructions are made. For special requirements, the operators need to be noted in the process documents and trained. For example, some conductors need to pass through the sheath before pressing, it needs to pre-install the conductor first and then return from the pre-installation station and then pressing; there is piercing pressing used to special pressing tools, this pressing method has good electrical contact performance.
Then there is the pre-assembly process. First of all, it is necessary to compile the operation instructions of the pre-assembly process. In order to improve the assembly efficiency, the pre-assembly station should be set for the complex harness. The rationality of the pre-assembly process directly affects the efficiency of the total assembly and reflects the technical level of a technician. If the pre-assembly part of the assembly is too small or the assembly guide path is not reasonable, it will increase the workload of the assembly staff, slow down the speed of the assembly line, so technicians should always stay on the scene and constantly summarize.
The final step is the assembly process. The assembly board designed according to the product development department can be coded, the specifications and sizes of tooling equipment and material box can be designed, and the numbers of all assembly sheaths and accessories can be pasted on the material box to improve assembly efficiency. Compile the assembly content and requirements of each station, balance the whole assembly station to prevent a little too much work and pull down the whole pipeline speed. To achieve the balance of workstations, technicians must be familiar with each operation and calculate the working hours on site, and adjust the assembly process at any time.
In addition, wiring harness technology also includes the preparation of material consumption quota list, man-hour calculation, worker training and so on. Because the technical content value is not high, these are not detailed. In a word, the electronic technology content and quality of automobile wiring harness in automobile are becoming an important index to evaluate the performance of automobile. Car manufacturers should pay special attention to the selection of wiring harness, and it is necessary to understand the process and production of automobile wiring harness.
