The production process of automobile wiring harness is revealed

After the online beam two-dimensional product drawing comes out, it is necessary to arrange the production process of the wire harness, and the process is inseparable for the service. Therefore, the two are combined and analyzed together.

1, open line process

The opening line is the first station for wire harness production. The accuracy of the wire 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 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. Create an opening operation manual and create a process tracking card.

2, crimping process

After the opening of the second production station, determine the crimping parameters according to the terminal type 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 pass through the sheath before they can be crimped. It needs to be pre-assembled and then returned from the pre-installation 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

Prepare the pre-installed process operation manual. In order to improve the assembly efficiency, the complex 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 continuously summarize the experience, so as to prepare a reasonable production process.

4, the assembly process

According to the assembly platen designed by the product development department, the tooling equipment and material box specifications are designed and the number of all assembly sheaths and accessories 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 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. The wire harness process also includes the preparation of material consumption quota schedules, working hours calculations, and worker training.

The wiring harness of the automobile is mainly based on the terminal wire, and the welding and molding are not too much, so the investment is mainly the terminal machine, and usually the semi-automatic terminal machine can be fully satisfied, and the fully automatic terminal machine is too wasteful, and there is Forming machine (about 20,000 or so), testing machine, tensile machine, peeling machine, cutting machine, soldering machine, electronic scale, punching machine.
