    Processing technology for automobile wire harness production

    First: stripping. The accuracy of stripping is directly related to the entire production schedule. Once an error occurs, especially if the opening size is short or long, it will lead to rework of all stations, which will take time and effort to affect production efficiency. Therefore, when stripping the wire, it is necessary to determine the opening size of the wire and the size of the stripping head according to the requirements of the drawing in combination with the terminal to be hit.

    Second: the crimping process. Determine the crimping parameters according to the type of terminal required by the drawings, and make the crimping operation manual. For the special requirements, indicate and train the operator on the process documentation. For example, some wires need to pass through the sheath before they can be crimped. It needs to be pre-assembled and then returned from the pre-installed station and then crimped. Also, the puncture-type crimping uses a special crimping tool. The crimping method has good electrical contact properties. And must test the tensile value of the terminal, if the tension is not up to the requirements, you need to re-adjust the crimping mold.

    Third: pre-installed. Firstly, the pre-installation process operation manual should be prepared. 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 and reflects the technical level of a craftsman. If the pre-installed part of the assembly is too small or the assembled wire path is unreasonable, the workload of the total assembly personnel will be increased, and the speed of the assembly line will be slowed down. Therefore, the process personnel should often stay on site to summarize.

    Fourth: the final assembly process. It can be programmed according to the product development department's assembly platen, design tooling equipment, material box size and all the assembly sheath and accessory numbers are attached 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 achieve a work station balance, the craftsman must be familiar with each operation and measure the working hours on site, and adjust the assembly process at any time.

    Wire harness production is mainly divided into two methods: end pressure (crimping) and forming. Nowhere is the best, it should be manufactured according to the requirements of the functional characteristics of the wire harness. And must fully inspect the product, test the wire's continuity, resistance, voltage, etc., to ensure product yield, to prevent defective products from entering the market.
