Abstract
Description
Technical Field
[0001] The utility model relates to the field of wire harness processing, and specifically relates to a wire harness shearing device. Background Art
[0002] With the rise of new energy industry, energy storage industry, data communication industry, medical industry, etc., the demand for wire harnesses increases, and the quality requirements are more stringent. In the wire harness processing industry, there are severe challenges in terms of processing efficiency, cost control, etc.
[0003] When processing wires with aluminum foil and shielding mesh, the existing technologies are laser cutting, rotary knife cutting, circumferential cutting of shielding mesh and manual scissors trimming.
[0004] When laser cutting aluminum foil (thin ones cannot be cut), it is necessary to adjust the focal length, focus, and the power is not easy to control. The processing efficiency is slow, smoke is generated, and it will also damage the shielding mesh (the aluminum foil is completely cut off, and 5 mm - 10 mm of the shielding mesh is retained) or the core wire insulation skin, etc. The product quality control is unstable.
[0005] When laser cutting the shielding mesh, it is necessary to adjust the focal length, focus, and the power is not easy to control. The processing efficiency is slow, smoke is generated, and it will also scald (cut) the core wire insulation skin. The product quality control is unstable.
[0006] When rotary knife cutting aluminum foil, the blade directly cuts the aluminum foil and makes a mechanical rotary motion. Because the aluminum foil is relatively thin, wound tightly, next to the core wire, and in an irregular circular shape, it is impossible to cut the aluminum foil.
[0007] When rotary knife cutting the shielding mesh, the blade directly cuts the shielding mesh and makes a mechanical rotary motion. Because the shielding mesh wires are relatively thin, wound tightly, next to the core wire insulation skin, and the core wire insulation skin is not an absolute circle and has dimensional tolerances. In order not to damage the core wire insulation skin, the cutting depth needs to be controlled, so 100% cutting cannot be guaranteed.
[0008] When circumferentially cutting the shielding mesh, two metal tubes are used in cooperation to cut off the shielding mesh. The requirements for the metal tube material and the cooperation degree are relatively strict, and the service life is low. For each wire specification, a set of tubes is required, resulting in a large number of tube specifications and a high switching frequency.
[0009] When manually trimming the aluminum foil and shielding mesh of wires, the quality can be guaranteed, but the output is relatively low and the labor cost increases. Content of the Utility Model

Detailed Embodiments
[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0034] As Figures 1 - 6 shown, this embodiment provides a wire harness shearing device, which includes three handling jaws 1 installed on a moving track 11, and the three handling jaws 1 are connected to the output end of a moving cylinder 3;
[0035] On one side of the moving track 11, there are provided an insulating skin cutting device, an aluminum foil cutting device, a de-insulating skin device, and a shielding net cutting device corresponding to the handling jaws 1; the jaws of the three handling jaws 1 are concentric with the centers of the cutting edges of the insulating skin cutting device, the aluminum foil cutting device, the de-insulating skin device, and the shielding net cutting device in sequence; fixed jaws 2 are respectively arranged in front of the cutting edges of the insulating skin cutting device, the aluminum foil cutting device, the de-insulating skin device, and the shielding net cutting device; the position of the fixed jaws 2 is in the middle between the handling jaws 1 and the cutting edges of the insulating skin cutting device, the aluminum foil cutting device, the de-insulating skin device, and the shielding net cutting device; and the cutting edges of the insulating skin cutting device, the aluminum foil cutting device, the de-insulating skin device, and the shielding net cutting device are equidistant left and right and at the same height up and down;
[0036] The aluminum foil cutting device includes two relatively arranged second cutting knives 5, and a high-frequency heater 7 is installed between the two second cutting knives 5.

[0046] The working process of the entire wire harness shearing device is as follows:
[0047] Adopt a fully automatic processing form. Manually place the wire on the handling gripper 1. The fixed gripper 2 at the first station clamps the wire.
