Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wire harness production, and specifically relates to a wire twisting machine for automobile wire harness production. Background Art

[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 or metal shell is added to form a component that connects the circuit. Among them, the twisted wire is an important part of the automotive wiring harness loop. It has the function of resisting signal interference. Many automotive wiring harness systems will use twisted wire to make the signal better transmitted.

[0003] In the prior art, the patent document with publication number CN 115346730 A discloses a device, a wire twisting machine and a method for realizing online point-wrap tape on a wire twisting machine, the device comprising a first rubber-wrapped head, a second rubber-wrapped head and a second twisting head driving mechanism; the second twisting head driving mechanism is used to be installed on the second twisting head, and is used to drive the second twisting head to rotate the second end of the twisted wire; the first rubber-wrapped head and the second rubber-wrapped head can be respectively installed on the rack on the side where the first twisting head is located and the side where the second twisting head is located, and are used to point-wrap tape on the glue-wrapped points at both ends of the twisted wire. The above technical solution realizes that the point-wrap tape is implemented synchronously and in parallel during the twisting process, but it can only twist one bundle of twisted wires at a time, and the work efficiency is relatively low. Moreover, since the twisting head bracket is fixedly arranged, the distance between the two twisting heads remains unchanged. However, during the twisting process, the entire bundle of twisted wires will continue to shorten, which is easy to tear off the wires inside the harness, and it is difficult to ensure the quality of the twisted harness.
