Automotive wiring harness assembly steps have?

1, car wiring harness open

Open line is the first station in the production of wire harness. Once the error occurs, especially the open wire size is too short, the accuracy of the open wire process is directly related to the entire production schedule, which will result in the rework of all the work stations and the laborious and time-consuming production efficiency. Therefore, in the preparation of open-line technology must be based on the drawings required to determine the reasonable open wire size, stripping size. Production of open-line operating instructions, production process tracking card.

2, automotive wiring harness crimping

The second production station after opening the line, make the operation manual of the crimping, confirm the crimping parameter according to the terminal type that the drawing requires. For special requirements need to be marked on the process file and train operators. For example: Some wires need to be passed through the sheath before crimping, you need to pre-installed wire and then return from the pre-installed station and then crimp; and punctured crimping used special crimping tools, this Crimping method has good electrical contact performance.

3, car wiring harness pre-installed

Preparation of pre-installed process instructions. Complex wiring harness should be installed pre-installed station, in order to improve the assembly efficiency. Prefabrication process is a reasonable or not directly affect the efficiency of the total assembly also reflects the level of technology of a craft staff. If the pre-installed partial assembly or the assembly line less reasonable unreasonable assembly will increase the workload of the assembly staff to slow the speed of the line so the craftsmen often stay in the field from time to time to sum up experience, so as to prepare a reasonable production process .

4, Automotive wiring harness assembly

According to the assembly board designed by the product development department, balance the entire assembly station to prevent excessive workload, design tooling equipment, material box size and size and affix the numbers of all assembly sheaths and accessories to the material box to improve the assembly efficiency . Preparation of various station assembly content and requirements, pulling down the entire pipeline speed situation. To achieve the station balance, the process staff must be familiar with each operation and on-site calculation of working hours, at any time to adjust the assembly process. Harness process also includes the preparation of data consumption quotas schedules, working hours, workers training and so on.
