[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 9 The wire harness bending device shown comprises: a clamping mechanism 1 and a bending mechanism; The clamping mechanism 1 is used to clamp the wire harness for movement; it should be noted here that the structure of the clamping mechanism 1 can be a combined clamping claw or a mechanical arm; The bending mechanism 2 has a rotating disc 21, which is arranged toward the clamping mechanism 1, and the rotating disc 21 has a rotating clamping member 21a; it should be noted that the rotating clamping member 21a clamps the wire harness on the rotating disc 21, and the specific clamping method can be a single clamping claw fixedly connected to a plane, or a combined clamping claw, for example, two protruding objects clamp the wire harness and bend the wire harness on the rotating disc 21; Among them, the clamping mechanism 1 clamps the wire harness close to or away from the bending mechanism 2, and the clamping mechanism 1 clamps the wire harness to the rotating disc 21, and the rotating clamping member 21a fixes one end of the wire harness, and bends the other end of the wire harness 180 degrees on the plane of the rotating disc 21, that is, the two ends of the wire harness are in parallel positions. One end of the wire harness is set to a fixed state, and this end is firmly fixed at the set position and will not move or change position in subsequent operations, which can ensure that the wire harness has a stable reference point during the bending or rotation process, thereby maintaining the stability and accuracy of the overall structure; the other end is clamped in the rotating clamping member 21a, such as Fig. 9 As shown in , this design allows the wire harness to be precisely bent to the desired set angle under control without causing position deviation or damage due to free movement; compared with the prior art, the wire harness can be controlled by the device and bent to the set angle at one time, avoiding damage to the wire harness, saving costs and improving work efficiency.

[0024] In some embodiments of the present invention, Figure 1 As shown in FIG. 1 , the clamping mechanism includes a horizontal moving member 11 and a vertical moving member 12, and the horizontal moving member 11 and the vertical moving member 12 move in the horizontal direction and the vertical direction respectively. It should be noted here that the specific structural form of the horizontal moving member 11 and the vertical moving member 12 can be a guide rail or a slide rail slider, which can be as follows Figure 1 As shown in the figure, the horizontal moving member 11 moves, and the vertical moving member 12 is slidably connected to the horizontal moving member 11. Alternatively, the vertical moving member 12 moves vertically, and the horizontal moving member 11 is slidably connected to the vertical moving member 12, so as to achieve accurate positioning of the wire harness and improve the efficiency of the device in bending the wire harness.

[0025] In some embodiments of the present invention, Figure 1 As shown in , the vertical moving member 12 is a parallel clamp, and the two clamps of the vertical moving member 12 move closer to or away from the wire harness. The structure of the parallel clamp can realize the precise control of the vertical position of the wire harness, ensure the stability of the wire harness during the bending process, and by adjusting the distance between the clamping arms and the clamping force, the parallel clamp can adapt to the clamping requirements of wire harnesses of different diameters and materials.

[0026] In some embodiments of the present invention, Figure 2-8 As shown in , the rotating clamp 21a includes a boss 21a1, one side of the boss 21a1 abuts against the wire harness, and the boss 21a1 rotates in a direction close to or away from the wire harness. It should be pointed out here that a groove for limiting the sliding of the wire harness can be provided on the side of the boss 21a1 close to the wire harness. Through such a setting, the wire harness can be bent smoothly on a plane, thereby improving the operating accuracy of the device. A component for limiting the sliding of the wire harness can also be provided on the other end of the wire harness opposite to the boss 21a1.

[0027] In order to further limit the bending of the wire harness on one plane and improve the bending accuracy, in some embodiments of the present invention, for example Figure 2-8 As shown in , on the rotating disk 21, an elastic abutment 21a2 is provided on the other side of the wire harness opposite to the boss 21a1. The elastic abutment 21a2 is L-shaped. The boss 21a1 and the elastic abutment 21a2 clamp the wire harness. A slot 21b matching the shape of the elastic abutment 21a2 is processed on the rotating disk 21. The elastic abutment 21a2 moves linearly in the slot 21b. Figure 2-4 As shown in 6-8, the rotating disk 21 can rotate. Before the wire harness is bent, the rotating disk 21 rotates in the direction of the wire harness. After the wire harness is bent, the elastic abutment 21a2 retracts, and the rotating disk 21 can rotate back to the initial position without obstruction to rotate the next wire harness, thereby improving the efficiency of the device.

[0028] In some embodiments of the present invention, Figure 1 As shown in FIG. 1 , the rotation of the rotating clamping member 21a is driven by the rotating driving member 21a, and the rotating driving member 3 controls the rotation of the rotating clamping member 21a. The specific structural form of the rotating driving member 3 can be as follows: Figure 1 The pulley shown in the figure may also be a gear, a sprocket, etc. The rotating drive member 3 may be controlled by a control system so that the rotating disc 21 can accurately rotate through a set angle to bend the wire harness to the set angle.

[0029] In some embodiments of the present invention, Figure 1 As shown in , the positioning mechanism 4 is of laser type, and a positioning hole 21c is provided on the rotating disk 21. The positioning mechanism 4 can be positioned by laser. When the laser passes through the positioning hole 21c of the rotating disk 21, it is confirmed that the rotating disk 21 has rotated to the set angle, and the rotating disk 21 stops rotating. The positioning point can also be set on the rotating disk 21 through an encoder wheel to determine the angle of rotation of the rotating disk 21.

[0030] In an embodiment of the present invention, there is also provided an aluminum wire harness processing device, comprising: The stripping mechanism includes two blades arranged opposite to each other. The blades are provided with a circular hole of a set aperture in the closed state. The blades can move toward or away from the wire harness and along the axial direction of the wire harness. For stripping the insulation layer of the wire harness, please refer to Fig. 9 ; The wire harness bending device according to any one of claims 1 to 8, wherein the wire harness bending device bends the peeled end of the wire harness, wherein one end of the wire harness is fixed, and the other end is clamped by a rotating clamp and rotated; the other end of the wire harness is bent 180°, such as Fig. 9 As shown, the two ends of the harness are parallel; The crimping device includes two crimping parts arranged opposite to each other, and the two crimping parts move toward or away from the wire harness. During the crimping process, the two crimping parts approach each other to form a crimping pattern. Fig. 9 The state shown is the cross-sectional view of the wire harness after crimping, as shown in Fig.10 As shown in FIG, after the crimping process is completed, the two crimping parts of the crimping device move away from each other.

[0031] In an embodiment of the present invention, a wire harness processing method is also provided. The above-mentioned aluminum wire harness processing device is used. The specific structural actions and effects of each step have been explained above. Those skilled in the art can understand it in combination with the above, and will not be repeated here. Figure 10-11 As shown in , the method comprises the following steps: S10: Place one end of the harness into the stripping area; S20: driving the two blades to move toward the wire harness by a set distance to cut the outer insulation of the wire harness, and then driving the blades to move along the axial direction of the wire harness to strip the insulation layer; S30: moving the wire harness to the wire harness bending device, bending the peeled part, one end of the wire harness is fixed, and the other end is clamped by a rotating clamp and rotated to bend the wire harness to a set angle; S40: Move the bent wire harness to a crimping device to crimp the wire harness.
