Description

Technical Field

[0001] The invention belongs to the technical field of wire harness processing, and in particular relates to a wire harness straightening device. Background Art

[0002] The wiring harness is a carrier for transmitting electrical energy. The automotive wiring harness is generally composed of one or several soft wires, and its conductor is mainly copper wire, which is encapsulated with an insulating layer on the outside. In the prior art, the wiring harness often bends or deforms due to reasons such as winding. In some working environments, excessive deformation of the wiring harness may cause problems in the use of the wiring harness, which is not conducive to the later processing of the wiring harness. Therefore, it is necessary to use a straightening device to straighten the wiring harness so that it is suitable for subsequent wiring harness processing such as passing through a plastic shell. At the same time, the impurities on the surface of the wiring harness need to be cleaned to avoid impurities remaining when passing through the plastic shell.
