As a result, the failure rate of increasingly complex wiring harnesses for automotive wiring harnesses also increases. This requires the improvement of the reliability and durability of the wire harness. Many people are interested in the technology and production of the automotive wire harness. Here, Nisshin Electric Co., Ltd. makes a brief description of the automotive wire harness technology and production knowledge. You only have to It takes a few minutes to read and you can get a general idea.
After the two-dimensional product drawing of the vehicle wiring harness comes out, the production process of the wiring harness is to be programmed. The process is inseparable from the service. Therefore, the author combines the production and process of the automotive wiring harness to analyze together.
The first station for wire harness production is the open line process. The accuracy of the open line process is directly related to the entire production schedule. Once errors occur, especially if the open line size is too short, all work stations will be reworked and time-consuming and laborious will affect the production efficiency. Therefore, in the preparation of the open line process must be based on the requirements of the drawings to determine the reasonable size of the open wire, stripping head size.
The second station after the open line is the crimping process. According to the type of the terminal required by the drawings, the crimping parameters are determined, and the crimping operation instructions are made. For the special requirements, the process documentation is required to indicate and train the operators. For example, some wires need to pass through the sheath before they can be crimped. It needs to be pre-wired and then returned from the pre-assembly station and then crimped; there is also a dedicated crimp tool for puncture crimping. This crimping method has good electrical contact properties.
Followed by the pre-installation process, first of all to prepare pre-installation process operating instructions, in order to improve the overall assembly efficiency, the complex wiring harness should be set up pre-installation station, the pre-installation process is reasonable or not directly affect the overall assembly efficiency also reflects a The technical level of the craftsmen is high and low. If the pre-installed part of the assembly is too few or the wire path of the assembly is unreasonable, the workload of the assembly personnel will be increased, and the assembly line speed will be slowed down. Therefore, the craftsman should always stay on site to summarize.
The final step is the assembly process. Can be compiled according to the product development department designed assembly platen, design tooling equipment, material box size and all the number of assembly jacket and accessories attached to the material box to improve the assembly efficiency. Compile the assembly contents and requirements of each station, and balance the entire assembly station to prevent excessive workload and pull down the entire assembly line speed. To achieve station balance, the craftsman must be familiar with each operation and measure the man-hours on site, adjusting the assembly process at any time.
In addition, the wire harness process also includes the preparation of material consumption rating schedules, time calculations, worker training, etc. Since the technical content value is not high, these will not elaborate. All in all, the content and quality of automotive wiring harness electronics in the car have gradually become an important indicator for evaluating vehicle performance. Automobile manufacturers should attach particular importance to the selection of wiring harnesses, and it is also necessary to understand the process and production of automotive wiring harnesses.
