Understand the major processes of automotive wire harness processing

The electronic technology content and quality of automotive wiring harnesses in the car has gradually become an important test indicator for evaluating the performance of automobiles. Automobile manufacturers should pay special attention to the choice of wiring harness. All the circuits in the car are transmitted through the wire harness. A small mistake may lead to the failure of the car to function or the disaster. The danger of this situation can be imagined. Here we introduce the several major processes of automotive wire harness processing

1. The opening process of automobile wire harness processing; the accuracy of the wire opening process is directly related to the entire production schedule. Once the error occurs, especially the short wire size is short, it will lead to the rework of all the stations, which will take time and effort to affect the production efficiency. Therefore, in the preparation of the opening process, it is necessary to reasonably determine the opening size and the size of the wire according to the requirements of the drawings.

2. Pre-installation process of automobile wire harness processing; firstly, the pre-installation process operation manual is prepared. In order to improve the assembly efficiency, the complicated wiring harness must be equipped with pre-installation station. The reasonable pre-installation process directly affects the efficiency of the total assembly. 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.

3. The crimping process of automobile wire harness processing; 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.

4. Assembly process of automobile wire harness processing; capable of compiling assembly platen designed according to product development department, designing tooling equipment, material box size and attaching all assembly sheath and accessory numbers to 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.
