Application of ultrasonic wire harness welding machine in automobile manufacturing industry
The automobile wiring harness is the main body of the automobile circuit. Without the wiring harness, there is no automobile circuit. The wiring harness refers to the connection between the contact terminal (connector) made of copper material and the wire and cable, and the external plastic insulator or external metal shell is used to connect the circuit assembly. The wiring harness industry chain includes industries such as wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream applications. The wiring harnesses are widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments, etc. The body wiring harness connects the whole body, and the body shape is H shape.
Ultrasonic wiring harness welding is a common process of automotive wiring harness welding. Its principle is to restructure the surface of the welding material through high-frequency vibration. Ultrasonic welding has the advantages of low energy consumption, no pollution, solid welding, low internal resistance, etc., without changing the welding The chemical properties of the parts and the welding conductivity are excellent.
Compared with traditional spot welding, ultrasonic wire beam welding has the following advantages:
1. Short welding time, greatly improved efficiency, fast welding time and energy saving.
2. Non-melting and fragile conductor characteristics of welding materials;
3. After welding, the conductivity is good, the strength is high, and the resistance system is extremely low or almost zero;
4. No need for flux, gas or solder;
5. No sparks, no smoke, environmental protection, and safe welding;
6. Stable welding process, online detection and control.
