With the continuous improvement of people's comfort, economy and safety requirements, the types of electronic products on the car is also increasing, the automotive wiring harness is becoming more and more complex wiring harness failure rate is also increased accordingly. This requires improving the reliability and durability of the harness performance, many people are more interested in the process and production of automotive wiring harnesses, here Haozhi electronics on the automotive wiring harness process and production of this knowledge to do a simple narrative, you only need to spend a few minutes to read, you can generally understand.
In the automotive wiring harness two-dimensional product drawings out of the wiring harness to be programmed after the production process, the process is to serve in the production of the two inseparable, so I will be the production of automotive wiring harnesses and the process of combining the two together to analyze.
Wire harness production of the first station is to open the line process. The accuracy of the open wire process is directly related to the entire production schedule, once the error is particularly short open wire size, will lead to rework of all stations, time-consuming and labor-intensive impact on production efficiency. So in the preparation of the open wire process must be based on the requirements of the drawings to determine the reasonable size of the wire open wire, stripping head size.
The second station after the open wire is the crimping process, according to the drawing requirements of the terminal type to determine the crimping parameters, the production of crimping instructions, 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 to a special crimping tool, this crimp has a good electrical contact performance.
Then there is the pre-installation process, first of all, to prepare the pre-installation process operating instructions, in order to improve the efficiency of the total assembly, the complexity of the wiring harness should be set up to pre-installation of the station, the pre-installation process is reasonable or not directly affects the efficiency of the total assembly 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 the craftsmen should often stay in the field and constantly summarize.
The last step is, the final assembly process. Able to compile according to the product development department designed assembly board, design equipment, material box specifications and size and will be all assembled sheaths 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 man-hours, at any time to adjust the assembly process.
In addition, the harness process also includes the preparation of material consumption quota schedule, time measurement, worker training, etc., due to the value of the technical content is not high, these are not detailed. In short, the automotive wiring harness in the car electronic technology content and quality, and gradually become an important indicator of the evaluation of automotive performance. Automobile manufacturers should pay particular attention to the choice of wiring harness, it is also necessary to understand the process and production of automotive wiring harness.
