Description

Technical Field

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., and the wiring harness is bundled to form a component connecting the circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and is generally H-shaped.

[0003] In the production and processing of automotive wiring harnesses, the wires at both ends need to be welded together by an ultrasonic welding machine, and then the heat shrink tube is wrapped at the welded joint by heat shrinking. The traditional method requires two different assembly lines to complete the above operations, but the welded joints may be disconnected during the transportation process before heat shrinking, resulting in the need for rework and re-welding. In addition, when producing and processing automotive wiring harnesses for new energy MPVs, due to the longer length of new energy MPVs, the traditional assembly line stations are inconvenient to place, so the assembly line needs to be lengthened, resulting in an increase in the area occupied by the assembly line; when welding traditional wiring harnesses, ultrasonic welding machines and heat shrink wrapping machines are usually fixed, so the wiring harness needs to be moved during welding or wrapping, which may cause the welded joints to be disconnected when the wiring harness is moved.
