With the gradual improvement of safety, economy and comfort requirements for the production process of automotive wiring harnesses, as well as the increasing number of electronic products used in automobiles, the failure rate increases with the use of complex wiring harnesses. This reliability and durability of the harness performance requirements become higher, many people do not understand the harness technology and production, we must use the technology and production of this knowledge to do an overview. After making the wiring harness production, the wiring harness production process should be arranged. The production process is inseparable from the service of both, so we combine the production and process analysis, and combine the two.

(A) The first automotive wiring harness production line processing station is open.

The accuracy of open production line technology is directly related to the production schedule. Once there is an error, especially the short size of the opening line, it may lead to rework of all stations, which consumes time and affects the production efficiency. Therefore, the opening line in the preparation process must be reasonable, according to the requirements of the opening line to determine the size of the wire, stripping head size.

(B) The second stop after opening the line is the crimping process.

Determine the crimping parameters according to the terminal type drawings. The crimping operation manual with special requirements shall be specified in the process documentation and training operators. For example: some need to be guided through the jacket before crimping, need to be pre-wired and then back from the preloaded contact station; The crimp that has been used to Pierce crimp crimp tools has good electrical contact properties.

(C) Then preconditioning.

In order to improve the assembly efficiency, complex automotive wiring harnesses must be set in advance. Whether the early processing is reasonable or not directly affects the efficiency of the final assembly process and reflects the technical level of a person's height. Too few lines or unreasonable workload of pre-assembled parts will increase the final assembly of personnel, and the line speed is slow, so the technicians should always keep summarizing the site.

(D) The final step is the assembly process.

Can be programmed according to the product development department design platen assembly, design tooling equipment, materials, box size and accessories jacket and all accessories number affixed to the material, to improve the efficiency of box assembly. The preparation and content of each station assembly is required to balance one point of work throughout the assembly station to prevent excessive drag down of the whole line speed. To achieve a balancing station, the process must be practiced during the core and estimated working hours of each scenario, adjusting the assembly process at any time.

In addition, the process also includes the preparation of fixed schedules of wire harness material consumption, job estimates, worker training, etc., which are not detailed. The content and quality of the overall use of automobile electronic technology has become an important index of automobile performance evaluation. For automobile manufacturers, wiring harness selection is particularly important, so it is necessary to understand the process and production of automobile wiring harness.
