Several processes for automotive wire harness processing

1: Open wire process. The accuracy of the opening process is directly related to the entire production schedule. Once an error occurs, especially if the opening size is short, it will lead to rework of all the stations, which will take time and effort to affect 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: Crimp process. Determine the crimping parameters according to the type of terminal required by the drawing, 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 be passed 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.

3: Pre-installed process. 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.

4: 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.
