Mobile WebSiteAfter the two-dimensional product drawing of the automotive wiring harness is produced, the production process of the photovoltaic ground wiring harness must be arranged. The two processes are inseparable for production. Therefore, the author analyzes the production and process of the automotive wiring harness together.
The first station for wire harness production is the wire-opening process. The accuracy of the line-opening process is directly related to the entire production progress. Once an error occurs, especially the short-line size, it will cause rework at all stations, which will take time and effort to affect production efficiency. Therefore, in the preparation of the wire opening process, it is necessary to reasonably determine the wire opening size and stripping size according to the requirements of the drawing.
The second station after the opening is the crimping process. The crimping parameters are determined according to the type of terminal required by the drawing, and the crimping operation manual is prepared. For special requirements, it is required to indicate and train operators on the process file. For example: some wires in the bridge boundary need to pass through the sheath before they can be crimped. It needs to be pre-assembled and then returned from the pre-installation station and then crimped. There are special crimps for puncture crimping. For welding tools, this crimping method has good electrical contact performance.
Next is the pre-assembly process. First, the pre-assembly process operation manual must be prepared. In order to improve the final assembly efficiency, a pre-assembly station must be set up for a complex wiring harness. The skill level of craftsmen. If there are too few pre-assembled parts or the wiring path of the assembly is not reasonable, it will increase the workload of the general assembly staff and slow down the speed of the assembly line, so the process staff must stay at the site and continue to summarize.
The final step is the final assembly process. Able to compile the assembly plate designed according to the product development department, design the tooling equipment, material box specifications and affix the numbers of all assembly sheaths and accessories on the material box to improve assembly efficiency. Map out the assembly content and requirements of each station, balance the entire assembly station to prevent a little workload, and reduce the entire line speed. To achieve station balance, the craftsman must be familiar with each operation and calculate the man-hours on site, and adjust the assembly process at any time.
In addition, the wiring harness process also includes the preparation of material consumption quotas, man-hour measurement, and worker training. These are not described in detail because the technical content is not high. All in all, the electronic technology content and quality of automotive wiring harnesses has gradually become an important indicator for evaluating automotive performance. Car manufacturers should pay particular attention to the selection of wiring harnesses. It is also necessary to understand the process and production of automotive wiring harnesses.
