What do you know about automotive wiring harness production and processes?

With the gradual increase in safety, economy, and comfort requirements for the production process of automotive wiring harnesses, as well as more and more electronic products used in automobiles, the failure rate increases accordingly with the use of complex wiring harnesses. This reliability and durability of the wiring harness performance requirements become higher, many people do not understand the wiring harness technology and production, we must make use of this aspect of technology and production here to do an overview. After the development of wire harness production, to arrange the wire harness production process, the production process is the service of the two are inseparable, so we will be production and process analysis to combine the two together.

(A) The first automotive harness line processing station was open. The accuracy of the open production line technology is directly related to the production schedule, once there is an error, especially the short size of the open wire, which may lead to rework of all the stations, time-consuming impact on productivity. Therefore, the open line in the preparation process must be reasonable, and the wire size and stripped head size should be determined according to the requirements of the open line diagram. (B) The second station after the open wire is the crimping process. Determine the crimping parameters according to the terminal type drawing, making special requirements for crimping operation manual should be specified in the process documentation and training of operators. For example: some need to be guided through the jacket back before crimping, need to be pre-wired, and then return from the pre-crimping station; once used to pierce the crimp crimping tool for this crimp has good electrical contact properties.

(C) and then pre-processing. First of all, the pre-preparation process operating instructions, in order to improve assembly efficiency, complex automotive wiring harnesses must be set up in advance, pre-processing reasonable or not directly affect the efficiency of the final assembly process also reflects the technical level of a person's height. Line if too little or pre-assembled parts assembled unreasonable workload will increase the total assembly of personnel, line speed is slow, so the process personnel should always keep summarizing the scene. (D) The final step is the assembly process. Can be programmed according to the product development department to design the platen components, design of tooling equipment, materials, box size and accessories jacket and all accessories number affixed to the material to improve the efficiency of the assembly box. The preparation and content of each station assembly requires that a little work is done to balance the entire assembly station to prevent excessive pulling down of the entire line speed. To achieve a balanced station, the process must be skillfully operated within the core of each scenario and the estimated work time to adjust the assembly process at any time.

In addition, the process includes preparation of fixed schedules for wiring harness material consumption, job estimation, worker training, etc., which are not described in detail. The overall utilization of the content and quality of automotive electronics has become an important indicator of automotive performance evaluation. For automobile manufacturers, wiring harness selection is particularly important, so it is necessary to understand the process and production under the automotive wiring harness.
