[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits; without it, there would be no automotive circuits. A wiring harness is a component consisting of copper-stamped contact terminals crimped onto wires and cables, then covered with plastic-molded insulation or a metal casing, forming a bundled connection to form a connected circuit. The wiring harness industry chain encompasses wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wiring harnesses are widely used in automobiles, household appliances, computers and communications equipment, and various electronic instruments and meters.

[0003] Traditional automotive wiring harness cutting is mostly done by staff, but this cutting method is generally inefficient, and the lengths of the cut wires may vary. As a result, the cut wires do not meet the cutting standards, resulting in waste. Utility Model Content

[0006] By adopting the above technical solution, the structure on the base plate is supported by the four supporting legs installed at the bottom of the base plate. Then, when the automobile wiring harness needs to be cut, the wiring harness is first limited to prevent it from deviating. Then, the staff can control the descending speed of the electric telescopic rod through programming, so that the error of the cut wiring harness length will not be too large. When the automobile wiring harness passes through the bottom of the mounting frame, it will be sensed by the infrared sensor. Then, when the infrared sensor senses the automobile wiring harness, it will send a signal to the controller to enable the controller to control the electric telescopic rod, so that the electric telescopic rod can cut the automobile wiring harness.

[0007] Preferably, a cutting plate is provided on the upper surface of the base plate directly below the mounting frame, a cutting groove is provided on the cutting plate, an inclined plate is fixedly installed on the rear end surface of the cutting plate, an infrared sensor is provided on the mounting frame, and the infrared sensor and the controller are electrically connected.

[0012] By adopting the above technical solution, the controller is used to control the lifting rod installed on the connecting frame, so that the lifting rod drives the limit frame to descend. Then, since the first limit groove and the second limit groove are provided on the limit frame and the fixed plate, this can better prevent the automobile wiring harness from deviating during forward transportation.

[0013] Preferably, a collecting groove is provided on the rear end surface of the bottom plate, a collecting box is inserted into the collecting groove, and a handle is fixedly installed on the outer end surface of the collecting box.

[0014] By adopting the above technical solution, the cut automotive wiring harnesses are collected through the collection trough. Then, when there are a large number of wiring harnesses collected in the collection trough, the staff can pull the collection box out of the collection trough through the handle installed on the outer surface of the collection box, thereby facilitating the staff to carry out subsequent processing of the cut automotive wiring harnesses.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The automatic cutting device for automobile wiring harnesses prevents the wiring harness from deviating by limiting its position. The staff can then control the descending speed of the electric telescopic rod through programming, so that the length error of the cut wiring harness will not be too large. When the automobile wiring harness passes through the bottom of the mounting frame, it will be sensed by the infrared sensor. When the infrared sensor senses the automobile wiring harness, it will send a signal to the controller to enable the controller to control the electric telescopic rod, so that the electric telescopic rod can cut the automobile wiring harness.

[0017] 2. The automatic cutting device for automobile wiring harness drives the active roller to rotate through the driving motor installed on the vertical plate. Then, when the automobile wiring harness passes between the active roller and the driven roller, the active roller drives the automobile wiring harness to be transported forward. Then, the lifting rod installed on the connecting frame can be controlled by the controller to make the lifting rod drive the limit frame to descend. Then, because the limit frame and the fixed plate are provided with the first limit groove and the second limit groove, this can better prevent the automobile wiring harness from deviating when being transported forward.
