1: thread stripping. The accuracy of stripping is directly related to the entire production schedule. Once there is a mistake, especially if the size of the opening line is too short or too long, it will lead to the rework of all stations, which will take time and affect the production efficiency. So when stripping wire must be based on the requirements of the drawings combined with the terminal to play a reasonable determination of the wire size, stripping size.

2: pressing technology. Determine the crimping parameters according to the terminal type required in the drawing, make the crimping operation manual, indicate the special requirements on the process document and train operators. For example, some wires need to pass through the sheath before they can be crimped. It needs to pre-install the wires and then return from the pre-installed station to be crimped. There are also puncture - type pressing to use a special pressing tool, this way of pressing has a good electrical contact performance. And must test the terminal tension value, if the tension does not meet the requirements need to re - adjust the clamping die.

3: pre-loading. In order to improve the assembly efficiency, preassembly stations should be set for complex wiring harnesses. The rationality of the preassembly process directly affects the efficiency of the assembly and reflects the technical level of a technician. If the preassembly part of the assembly is too small or the wire path of the assembly is not appropriate, the workload of the general assembly personnel will be increased and the speed of the assembly line will be slowed down, so the process personnel should stay on the site to make continuous summary.

4: final assembly process. Be able to make assembly table according to the design of product development department, design tooling equipment, material box size and number of all assembly jackets and accessories on material box to improve assembly efficiency. Compile the assembly content and requirements of each station, balance the whole final assembly station to prevent excessive workload and the whole assembly line speed. To achieve the balance of work positions, the process personnel must be familiar with each operation, calculate the working hours on site, and adjust the assembly process at any time.
