Process Analysis of Automotive Wiring Harness

The accuracy of wire stripping is directly related to the production progress of the entire automotive wiring harness process. Once errors occur, especially when the wire size is too short or too long, it will lead to the rework of all stations, which is time-consuming and laborious and affects the production efficiency. Therefore, when stripping, it is necessary to reasonably determine the opening size and stripping size of the wire according to the requirements of the drawing and the terminal to be punched. The crimping process shall determine the crimping parameters according to the terminal type required in the drawing, prepare the crimping operation instructions, and indicate the special requirements in the process documents and train the operators. For example, some wires need to pass through the sheath before crimping, and they need to be pre-assembled and returned from the pre-assembly station before crimping; there is also a special crimping tool for piercing crimping, which has good electrical contact performance. Be sure to test the tension value of the terminal. If the tension fails to meet the requirements, it is necessary to readjust the crimping die. In order to improve the efficiency of final assembly, pre-assembly stations should be set for complex wiring harnesses. Whether the pre-assembly process is reasonable or not directly affects the efficiency of final assembly and also reflects the technical level of a technician. If the pre-assembly part is assembled too little or the assembly wire path is unreasonable, it will increase the workload of the general assembly personnel and slow down the speed of the assembly line, so the process personnel should often stay on site and constantly summarize. The final assembly process can design the specifications and dimensions of tooling equipment and material boxes according to the assembly platen designed by the product development department, and paste the numbers of all assembly sheaths and accessories on the material boxes to improve the assembly efficiency. Compile the assembly content and requirements of each station, balance the whole assembly station to prevent the situation that the workload is too large and the speed of the whole assembly line is pulled down. To achieve station balance, technicians must be familiar with each operation and calculate the working hours on site, and adjust the assembly process at any time.
