Mobile WebSiteAs people's demands for comfort, economy, and safety continue to increase, the variety of electronic products on the car is also increasing, and the failure rate of the increasingly complicated wiring harness of the automobile wire harness is correspondingly increased. The automotive wiring harness requires the improvement of the reliability and durability of the wiring harness. Many people are interested in the technology and production of the automotive wiring harness. Here, Hao Zhi Electronics makes a brief description of the automotive wiring harness technology and production knowledge. It only 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 the time and effort of the motorcycle harness 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.
Then there is the pre-installation process. Firstly, the pre-installation process operation manual should be compiled. In order to improve the assembly efficiency, the complicated wiring harness must be equipped with pre-installation stations. The reasonableness of the pre-installation process directly affects the efficiency of the total assembly. The technical level of the craftsman is high. If the pre-assembled part is less assembled or the assembled wire path is unreasonable, the workload of the total assembly personnel will be increased, and the connector plug slows down the speed of the assembly line, so the process personnel should often stay on site to summarize.
The final step is the final assembly process. It can be programmed according to the assembly board designed by the product development department, design tooling equipment, material box size and attach the number of all assembly sheaths and accessories to the material box to improve assembly efficiency. Compile the assembly content and requirements of each station, balance the entire assembly station to prevent a situation where the workload is too large and pull down the entire assembly line speed. In order to balance the work station, the craftsman must be familiar with each operation and measure the working hours on site, and adjust the assembly process at any time.
In addition, the wire harness process also includes the preparation of material consumption quota schedules, working hours calculations, worker training, etc., because the technical content is not high, these will not be elaborated. In a word, the content and quality of the automotive wiring harness in the car, the car audio harness has gradually become an important indicator to evaluate the performance of the car. Automobile manufacturers should pay special attention to the choice of wire harnesses, and it is also necessary to understand the process and production of automobile wiring harnesses.
