Processing of automotive wire harness production

Stripping. Stripping accuracy is directly related to the entire production schedule, once the error is particularly short or long open wire size, will lead to rework of all the workstations, time-consuming and laborious impact on production efficiency. So when stripping the wire must be based on the requirements of the drawings combined with the terminals to be played to reasonably determine the size of the open wire, stripping the head size. Second, crimping process. According to the drawing requirements of the terminal type to determine the crimping parameters, the production of crimping operation manual, for special requirements need to be specified in the process documentation and training of operators. For example: some wires need to pass through the sheath before crimping, it needs to be pre-installed wire and then return from the pre-installation station and then crimp; there are also piercing crimp with a special crimping tool, this crimping method has good electrical contact properties. And be sure to test the value of the tension of the terminal, if the tension does not meet the requirements will need to re-adjust the crimping mold. Third, pre-assembly. First of all, we must prepare a pre-assembly process operating instructions, in order to improve the total assembly efficiency, complex wiring harnesses should be set up to pre-assembly station, pre-assembly process is reasonable or not directly affects the total assembly efficiency also reflects the technical level of a craftsman high and low. If the pre-assembly part of the assembly is less or assembly of the wire path is unreasonable will increase the workload of the total assembly personnel, slowing down the speed of the assembly line, so craftsmen should often stay in the field and constantly summarize. Fourth, the general assembly process. Able to compile according to the product development department designed assembly board, design equipment, material box specifications and size and will be assembled all the sheath and accessories of the number affixed to the material box in order to improve the assembly efficiency. Preparation of each station assembly content and requirements, balancing the entire assembly station to prevent a point of excessive workload, pulling down the speed of the entire assembly line. To achieve workstation balance, process personnel must be familiar with each operation and on-site measurement of working hours, adjust the assembly process at any time.
