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.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field 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.

[0033] like Figures 1 to 8 The wire harness tape wrapping device shown in the figure is as follows Figure 1 As shown in the figure, the device includes a frame 1, a winding mechanism 2, a reeling mechanism 3, a tape pulling mechanism 4 and a tape cutting mechanism 5. Please continue to refer to Figure 1 When the wire harness is wrapped with tape, firstly, the tape pulling mechanism 4 clamps the end of the tape and pulls it straight downward so that the tape covers the wrapping mechanism 2, and the tape cutting mechanism 5 cuts the tape, and then the wire harness is pressed against the tape and extends into the wrapping mechanism 2, and the remaining part of the tape is wrapped and bonded to the wire harness through the rotation of the wrapping mechanism 2;

[0034] Please refer to Figure 2 In some embodiments of the present invention, the frame 1 has an open slot 11 arranged toward one side, and the opening slot 11 is arranged to facilitate inserting the coil together with the tape into the winding mechanism 2. The specific inserting method is as follows Figure 3 As shown in the figure, the circle represents the cross section of the cable. Of course, it should be pointed out here that it can be a single cable or multiple cables; please continue to refer to Figure 1 and Figure 2 In some embodiments of the present invention, the winding mechanism 2 includes a C-shaped gear ring 21 rotatably connected to the opening slot 11, and the opening of the C-shaped gear ring 21 is set in the same direction as the opening slot 11 when it is in the initial position; please continue to refer to Figure 1 In the embodiment of the utility model, the unwinding mechanism 3 is fixed on the frame 1 and is used for unwinding the tape; the tape pulling mechanism 4 is arranged on the frame 1 and is movably arranged in the vertical direction of the side where the opening groove 11 is located, and the tape pulling mechanism 4 has a clamping claw 41 for clamping the end of the tape and pulling it to the lower side of the opening groove 11; the tape cutting mechanism 5 is arranged on the frame 1 and is arranged above the opening of the opening groove 11, and is used for cutting the tape.

[0035] In the above embodiment, the tape pulling mechanism 4 is provided to replace the roller conveying in the prior art, and the tape end is clamped by the clamping claw 41 and then pulled in the vertical direction, thereby reducing the contact with the equipment on the frame 1, thereby improving the reliability of tape winding.

[0036] Based on the above embodiment, the rotation drive form of the C-shaped gear ring 21 is as follows: Figure 2As shown in the figure, the winding mechanism 2 also includes two driven gears 22 both meshed with the C-shaped gear ring 21, at least one of the two driven gears 22 remains meshed with the C-shaped gear ring 21 during the rotation process, and also includes a motor 23 that is simultaneously meshed with the two driven gears 22. By such an arrangement, there is always one driven gear 22 meshed with the C-shaped gear ring 21, so that the C-shaped gear ring 21 can be rotated for multiple turns, thereby ensuring that the tape is completely wound on the wiring harness.

[0037] In some embodiments of the present invention, in order to ensure that the tape can be reliably attached to the cable, such as Figure 2 As shown in the figure, the C-shaped gear ring 21 also has two oppositely arranged clamping members 21a, and the two clamping members 21a are arranged in an arc-shaped expansion toward the opening of the C-shaped gear ring 21, and the two clamping members 21a also form an arc-shaped groove 21b at the center of the C-shaped gear ring 21. Through such an arrangement, the free end of the tape can continuously fit with the cable during the rotation of the gear ring, so that all the tapes are wound around the cable. In addition, in the embodiment of the utility model, in order to adapt to cables of different sizes, please continue to refer to Figure 2 The two pressing members 21a are movably arranged in the pressing direction and are pressed by the elastic member 21c. The elastic member 21c here can be a spring or other elastic object. The elastic contact mode of the pressing member 21a can improve the applicability of the device.

[0038] Please refer to Figure 1 and Figure 4 In some embodiments of the present invention, in order to improve the consistency of the connection between the cable and the tape when the cable enters the clamping member 21a, a glue clamp 12 is arranged at the opening slot 11 of the frame 1. The opening of the glue clamp 12 is V-shaped, and two glue rollers 12a are provided at the tail end of the V-shaped opening. The wire harness enters the C-shaped gear ring 21 after being rolled by the two glue rollers 12a. In addition, in the embodiment of the present invention, the tape cutting mechanism 5 is arranged near the opening slot 11. In this way, when the wire harness passes through the two glue rollers 12a, the wire harness 12a is cut into the tape. Figure 3 As shown in , the upper end of the tape has been attached to the cable and the remaining tapes. Through the arrangement of this structure, the slipping of the tape when the C-shaped gear ring 21 rotates can be avoided, thereby improving the reliability of the tape winding.

[0039] Please refer to Figure 5 and Figure 6 The clamping jaw 41 includes a straight jaw 41a and an L-shaped jaw 41b disposed opposite to the straight jaw 41a. The short arm of the L-shaped jaw 41b is disposed opposite to the straight jaw 41a, and the two form a rectangular opening clamping structure. Figure 5 As shown in , the clamping size of this rectangular opening clamping structure is small, which is convenient for extending into the tape cutting mechanism 5 to pull the cut tape for the next time, thereby improving the reliability of tape clamping.

[0040] Regarding the tape pulling mechanism 4, the tape pulling mechanism 4 also includes an extension arm 42 fixedly connected to the clamp 41, a slide rail 43 slidably connected to the extension arm 42, and a screw drive assembly 44 for driving the extension arm 42 to rise and fall. The screw drive assembly here is a conventional motor 23 screw nut seat structure, which is a conventional technical means in this field, and its specific structure is not repeated here. It should be pointed out here that in the embodiment of the utility model, the opening clamping structure of the clamp 41 is arranged opposite to the tape cutting mechanism 5. When the clamp 41 rises to the highest point, it just extends into the position where the tape cutting mechanism 5 cuts the tape, so as to achieve the clamping of the tape for the next time.

[0041] Please refer to Figure 4 , Figure 7 and Figure 8 In some embodiments of the present invention, the tape cutting mechanism 5 includes a movable knife 51 and a fixed knife 52 arranged opposite to each other, and the size of the clamping mechanism is adapted to the distance between the movable knife 51 and the fixed knife 52. Figure 8 The movable knife 51 has two sides in the width direction of the limit blocks 51a protruding toward the fixed knife 52. In this way, through the setting of the limit blocks 51a, the clamping structure is just inserted between the movable knife 51 and the fixed knife 52, thereby improving the reliability of clamping the end of the tape next time.
