Detailed ways

The principle of the utility model is that the production process of the wire harness sequentially includes the processes of wire opening, crimping, pre-assembly and final assembly. The accuracy of the wire-opening process is directly related to the entire production schedule. Once an error occurs, especially if the wire-opening size is too short, it will lead to rework of all stations, which is time-consuming and labor-intensive and affects production efficiency. In the crimping process, the crimping parameters are determined according to the terminal type required by the drawing, and the crimping operation manual is produced. For those with special requirements, it is necessary to indicate on the process document and train the operator. In the pre-assembly process, the pre-assembly process operation manual must be compiled first. In order to improve the efficiency of the final assembly, a pre-assembly station must be set for complex wiring harnesses. If the pre-assembled part is assembled too little or the wire path of the assembly is unreasonable, it will increase the workload of the general assembly personnel. In the final assembly process, according to the assembly platen designed by the product development department, design the tooling equipment, the specifications and dimensions of the material box, and paste the numbers of all the assembly sheaths and accessories on the material box to improve the assembly efficiency.
