[0002] The wiring harness of new energy vehicles is the network body of the automobile circuit. Without the wiring harness, there would be no automobile circuit. The wiring harness refers to the contact terminal (connector) punched from copper material, which is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component connecting the circuit by bundling with a wiring harness.

[0003] During the production process of automotive wiring harnesses, cutting operations are required to meet actual needs. Traditional wiring harness cutting devices mostly use manual cutting when working. This working method is very labor-intensive and resource-intensive, and has low production efficiency and high error rate, which ultimately leads to low cutting length accuracy of the wiring harness.

[0004] In order to solve the problems raised in the above-mentioned technology, for example, application number CN201820063497.5 discloses a wire harness cutting machine, including a base, a wire releaser and a support frame; wherein the wire releaser and the support frame are respectively arranged on the base, a cutting knife and a cutting table that cooperate with each other to cut the wire harness are arranged on one side of the support frame, and an electric chuck is arranged on the other side; one end of the wire harness to be cut is wound on the wire releaser, and one end of the wire harness to be cut is pulled out from the wire releaser, passes through the through hole on the support frame into the interior, passes through the cutting area between the cutting knife and the cutting table, and is clamped by the extended electric chuck; then, the electric chuck is controlled to shorten and drag the wire harness to the required length and then stop, and the cutting knife is driven to cut vertically downward and cooperate with the cutting table to cut the wire harness, but the device still has the following defects: Although the above device can cut the wire harness by driving the cutting knife to cut vertically downward and cooperate with the cutting knife table to cut the wire harness, which is more time-saving and labor-saving, the wire harness can only be cut one by one, resulting in slow cutting speed and low working efficiency.

[0005] In order to solve the problems raised in the above-mentioned technology, for example, application number CN202221200516.7 discloses a wire harness efficient cutting device for wire harness assembly, including a fixed column, a cutting support platform, a wire harness efficient cutting device and a wire harness winding device, wherein the cutting support platform is arranged on the fixed column, the wire harness efficient cutting device is arranged on the cutting support platform, the wire harness winding device is arranged on the cutting support platform, the wire harness efficient cutting device includes a support frame, a drive motor, a rotating transmission screw, a screw support plate, a connecting seat slide groove, a connecting seat slider, a mobile connecting seat, a lifting hydraulic rod and a mobile cutting knife, the support frame is arranged on the cutting support platform, the drive motor is arranged on the support frame, the rotating transmission screw is arranged on the drive motor, and the screw support plate is arranged on the rotating transmission screw, but the device still has the following defects: Although the above device can separate different groups of wire harnesses through the wire harness separator ring, so that multiple wire harnesses can be cut at one time, the lack of pressing and clamping components causes the wire harnesses to be unable to be straightened, which can easily lead to problems of mutual entanglement and low cutting quality.
