After the two-dimensional product drawings in the automotive wiring harness, to arrange the production process of the wiring harness, the process is to serve the production of the two inseparable, so the author will be the production of automotive wiring harness and the process of the two combined together to analyze.
The first station in the production of wire harnesses is the open wire process. The accuracy of the open wire process is directly related to the entire production schedule, once the error is particularly open wire size is short, will lead to all stations of rework, time-consuming and labor-intensive impact on production efficiency. Therefore, in the preparation of the open wire process is to be sure to determine the wire size according to the requirements of the drawings, stripping the size of the head.
The second station after the opening of the wire is the crimping process, according to the drawing requirements of the terminal type to determine the crimping parameters, the production of crimping operation instructions, for special requirements need to be indicated in the process documentation and training operators. For example: some wires need to go through the sheath before crimping, it needs to be pre-assembled wire and then return from the pre-assembly station before crimping; there is a piercing crimp using a special crimping tool, this crimping method has good electrical contact performance.
Next is the pre-assembly process, first of all to prepare the pre-assembly process operating instructions, in order to improve the overall efficiency, complex wire harnesses are set up pre-assembly stations, pre-assembly process is reasonable or not directly affect the efficiency of the total assembly also reflects the technical level of a craft personnel. If the pre-assembly part of the assembly of 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 the process personnel should often stay on site to constantly summarize.
The final step is that the assembly process. According to the product development department design of the assembly board, the design of assembly equipment, material box specifications and size and all assembly sheath and accessory numbers on the material box to improve assembly efficiency. Prepare the assembly content and requirements of each station, and balance the whole assembly station to prevent the situation that one point of work is too much and pulls down the speed of the whole assembly line. To achieve a balanced workstation, process personnel must be familiar with each operation and on-site measurement of working hours, and adjust the assembly process at any time
The automotive wiring harness is the main body of the network that connects and enables the electrical and electronic components of the car to function, and without the harness there would be no automotive circuitry. At present, regardless of whether it is a high-class luxury car or an economical ordinary car, the form of wiring harness is basically the same, which is composed of wires, joint plug-ins and wrapping tapes. It is necessary to ensure the transmission of electrical signals as well as the reliability of the connected circuits, to supply the specified current value to the electrical and electronic components, to prevent electromagnetic interference to the surrounding circuits, and to exclude electrical short circuits.
