In summary, the winding device of the utility model has a compact structure, is simple and small, occupies a small space, and is installed on the winding machine and linked with the winding equipment, which reduces the number of clamping and positioning times, saves production time, and greatly improves production efficiency.

[0033] Example 2

[0034] Based on the structure of Example 1, Figure 1-3 As shown, the winding box 1 is provided with a support hole 14 which passes through the winding box 1, and the support hole 14 is arranged corresponding to the driven pulley 32.

[0035] like Figure 1-3 As shown, the winding mechanism 3 also includes a tensioning assembly, which includes a motor seat 37, a threaded plate 38, and an adjusting plate 39. The servo motor 34 is fixed on the motor seat 37. The motor seat 37 is arranged outside the winding box 1 and sleeved on the end of the servo motor 34. The motor seat 37 is connected to the threaded plate 38 located inside the winding box 1 by a screw passing through the winding box 1. The winding box 1 is provided with a long hole corresponding to the screw. The adjusting plate 39 is arranged on one side of the motor seat 37, and is provided with an adjusting screw (not shown in the figure) that cooperates with the motor seat 37. The tension of the annular synchronous belt is adjusted by the tensioning assembly to prevent the driven pulley 32 from running empty.

[0036] Among them, Figure 1-3 As shown, the winding box 1 comprises a box body 12 and a box cover 13. The box cover 13 is arranged on a side of the box body 12 where an opening is provided, and is detachably connected to the box body 12 through a fastener, and has a simple structure and is convenient for disassembly and assembly. The clamping mechanism 2 and the winding mechanism 3 are basically integrated inside the winding box 1, and have a compact structure and a protective function.

[0037] In addition, if Figure 1-4As shown, the open slot 11 is provided with a wire plate 5 which is arranged opposite to each other up and down. The wire plate 5 is an L-shaped plate with rounded corners to facilitate the entry of the wire harness and avoid damage to the wire harness.

[0038] In addition, if Figure 1-5 As shown, the driving assembly includes a cylinder 22, a push block 23, and a cam block 24. The cylinder 22 is fixed in the winding box 1, and a push block 23 is provided at its output end. The inner side of the winding box 1 is provided with a slide groove 15 slidably connected to the push block 23, and the slide groove 15 guides the movement of the push block 23. There are two cam blocks 24, which are arranged opposite to each other and correspond to the two clamps 21 one by one. The cam block 24 is L-shaped, and a rotating shaft 25 is inserted at its corner position, and it is rotatably connected to the driven pulley 32 through the rotating shaft 25. The end of the cam block 24 that is close to it is a driving part 241 that is movably connected to the push block 23, and the other end of the cam block 24 is a push-open part 242, and the push-open part 242 is connected to the clamp 21.

[0039] like Figure 2-6 As shown, in order to avoid the collision between the driven pulley 32 and the driving assembly when it rotates, the driving assembly also includes a movable push block 26. The driven pulley 32 is provided with a second slide groove 322 connected to the vertical groove of the T-slot 321. The second slide groove 322 is arranged parallel to the first slide groove 15. The movable push block 26 is embedded in the second slide groove 322 and is slidably connected to the second slide groove 322. The second slide groove 322 guides the movement of the movable push block 26 and makes the moving directions of the push block 23 and the movable push block 26 in a straight line. The movable push block 26 is arranged on the side of the push block 23 away from the second cylinder 22 and is movably connected to the push block 23. A groove 261 is provided on the side of the movable push block 26 away from the push block 23, and the driving parts 241 of the two cam blocks 24 are inserted in the groove 261. The groove can limit the rotation angle of the driving part 241. Specifically, a limiting shaft cooperating with the driving part is inserted in the groove 261, and the limiting shaft limits the rotation angle of the driving part 241; the pushing part 242 extends from the second slide groove 322 into the T-slot 321 and is connected to the clamping plate in the T-slot 321. The clamping state of the two clamping plates 21 is limited by the cooperation of the cam block 24, the movable push block 26 and the spring 27 to ensure stable clamping and prevent the wiring harness from slipping out of the clamping plate when winding.

[0040] like Figure 2 , 5 As shown, the driving assembly also includes a spring 27. A plurality of springs 27 are provided on the side where the two clamps 21 are away from each other. One end of the spring 27 is connected to the clamping portion 211 of the clamp 21, and the other end is connected to the side wall of the T-slot 321. In addition, a plurality of springs 27 are arranged along both sides of the guide portion 212, so that the elastic force direction of the spring 27 is in the vertical direction, thereby ensuring that the clamps are evenly stressed and clamped stably.

[0041] like Figure 2-6 As shown, the clamping plate 21 includes a vertically arranged clamping portion 211 and a guiding portion 212. The clamping surface of the clamping portion 211 is provided with anti-slip grooves and has good clamping force. The vertical groove of the T-slot 321 is provided with a sliding groove 323 corresponding to the guiding portion 212. The guiding portion 212 is inserted in the sliding groove 323 and is slidably connected with the sliding groove 323.

Specifically, a limiting groove is provided in the guiding portion 212, and the pushing portion 242 extends into the limiting groove. The clamping plate 21 is driven to open by the cam block 24 connecting the pushing portion 242 and the limiting groove.

[0042] The working principle of the clamping mechanism 2 is as follows: in the initial state, the two clamps 21 are closed under the action of the spring 27, and the push block 23 is separated from the movable push block 26; when the clamps 21 need to be opened, the output end of the cylinder 22 extends, and the push block 23 extends forward, first abuts against the movable push block 26, and then pushes the movable push block 26 to move toward the direction of the opening slot 11, and the movable push block 26 pushes the driving part 241 of the cam block to rotate, so that the push-opening parts 242 of the two cam blocks rotate and open toward the outside, thereby driving the two clamps 21 to move in the direction away from each other under the elastic force of the spring 27, and the two clamps 21 are opened, and the wire can be fed. After the wire is fed, the output end of the cylinder 22 retracts, and the push block 23 is also reset in sequence, and the two clamps 21 are closed again under the elastic force of the spring 27, and the movable push block 26 is reset under the reverse force of the push-opening part of the cam block 24.
