In modern automobiles, there are many wiring harnesses, and the electronic control system is closely related to the wiring harness. Someone once made an image analogy: if the functions of computers, sensors and executing elements are compared with human bodies, the manufacturers of automobile lamp wiring harness can say that computers are equivalent to human brain, sensors are equivalent to sensory organs, executing elements are equivalent to motor organs, and automobile lamp wiring harness manufacturers, then wiring harness is nerve and nerve. Blood vessels. Automobile wiring harness is the main body of the network of automobile circuit. It connects the electrical and electronic components of automobile and makes them function. Without wiring harness, there will be no automobile circuit. Automobile brand, at present, whether it is a luxury car or an economical ordinary car, the form of wiring harness is basically the same. It consists of wires, plug-ins and wrapping tape. It not only ensures the transmission of electrical signals, but also ensures the reliability of the connecting circuit to supply electronic and electrical components. The prescribed current value prevents electromagnetic interference to the surrounding circuit and eliminates short circuit of the electrical apparatus.
As for the pre-assembly process, the first task is to make KIT from the plastic parts with open and pressed wires according to the process instructions, which will help to reduce the investment cost of assembly line equipment, reduce the difficulty of assembly operation and reduce the total assembly operator. For simple automobile wiring harness, it can be cancelled directly, but for complex automobile wiring harness, the prefabrication station should be set first; then the assembly process, according to the process instructions, the prefabricated wiring harness will be arranged orderly on the assembly tooling board, and finishing the wiring harness, winding tape, binding karting, installation of rubber parts and other accessories. The last is the post-assembly process, which includes installation bracket, live detection, full size detection and bundling packaging.
The first station in the production of automobile wiring harness is the opening process. The accuracy of the opening process is directly related to the overall production schedule. Once errors occur, especially the opening size is too short, it will lead to the rework of all stations, which will take time and effort to affect the production efficiency. Therefore, in compiling the opening process, it is necessary to determine the opening size and stripping size of the conductor reasonably according to the requirements of the drawings. The second position after the opening of the line is the crimping process. The crimping parameters are determined according to the terminal types required in the drawings. The crimping operation instructions are made. For special requirements, the operators need to be noted in the process documents and trained. For example, some conductors need to pass through the sheath before pressing, it needs to pre-install the conductor first and then return from the pre-installation station and then pressing; there is piercing pressing used to special pressing tools, this pressing method has good electrical contact performance.
Automobile wiring harness is the main body of the network of automobile circuit. It connects the electrical and electronic components of automobile and makes them function. Without wiring harness, there will be no automobile circuit. At present, whether it is a high-grade luxury car or an economical ordinary car, the form of wire harness is basically the same. It consists of wires, connectors and tape wrapping. It not only ensures the transmission of electrical signals, but also ensures the reliability of the connecting circuit, supplies the prescribed current value to the electronic and electrical components, and prevents the electricity from the surrounding circuit. Magnetic interference and short circuit should be eliminated. The new energy vehicle harness can be divided into two types: the power line carrying the actuator power and the signal line transmitting the input instruction of the sensor.
