[0019] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of an electronic wire harness tape anti-pull-out winding device provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the moving component. Figure 3 for Figure 1 The diagram shows the structure of the driving component.

[0020] An electronic wire harness tape anti-pull-out wrapping device includes: a base plate 1; Movable component 2, which is disposed on the top of the base plate 1; The drive assembly 3 is disposed on the top of the base plate 1. The drive assembly 3 includes a support frame 31, a second drive motor 32, a rotating rod 33, two first synchronous pulleys 34, two synchronous belts 35, and two second synchronous pulleys 36. The support frame 31 is fixedly installed on the top of the base plate 1. The second drive motor 32 is fixedly installed on one end of the support frame 31. The rotating rod 33 is fixedly installed on the output end of the second drive motor 32. The two first synchronous pulleys 34 are respectively fixedly installed on both ends of the outer side of the rotating rod 33. The two synchronous belts 35 are respectively sleeved on the outer side of the two first synchronous pulleys 34. The two second synchronous pulleys 36 are respectively disposed inside the two synchronous belts 35. Adjustment component 4 is disposed on the top of drive component 3. Adjustment component 4 includes fixed tube 41, extension rod 42 and locking screw 43. Fixed tube 41 is rotatably connected to the inside of the other end of support frame 31. Fixed tube 41 is also fixedly installed on the outer side of a second synchronous pulley 36. Extension rod 42 is slidably connected to the inside of fixed tube 41. Locking screw 43 is threaded to the inside of the top of fixed tube 41 and its bottom abuts against the top of extension rod 42. Two clamping components 5 are respectively disposed at both ends of the top of the drive component 3.

[0021] The movable component 2 includes a mounting frame 21, a first drive motor 22, a threaded rod 23, a movable plate 24, a rotating shaft 25, and a take-up shaft 26. The mounting frame 21 is fixedly mounted on the top of the base plate 1. The first drive motor 22 is fixedly mounted on one end of the mounting frame 21. The threaded rod 23 is fixedly mounted on the output end of the first drive motor 22. The movable plate 24 is threadedly connected to the outer side of the threaded rod 23 and slidably connected to the bottom of the inner side of the mounting frame 21. The rotating shaft 25 is rotatably connected to one side of the movable plate 24. The take-up shaft 26 is fixedly mounted on the outer side of the rotating shaft 25.

[0022] Both clamping assemblies 5 include a clamping frame 51, two drive telescopic rods 52 and two clamping plates 53. The two drive telescopic rods 52 are respectively fixedly installed on the top and bottom of the clamping frame 51, and the two clamping plates 53 are respectively fixedly installed on the moving ends of the two drive telescopic rods 52.

[0023] One of the clamping frames 51 is fixedly installed on the side of another second synchronous pulley 36, and the other clamping frame 51 is fixedly installed on one end of the extension rod 42.

[0024] The first drive motor 22 is a servo motor, fixed to one end of the mounting bracket 21 via a flange. It has an adjustable speed function and can precisely control the rotation speed of the threaded rod 23 through the control system, thereby adjusting the feed rate of the moving plate 24. One end of the threaded rod 23 is connected to the output shaft of the first drive motor 22 via a coupling, and the other end is rotatably supported on the other end of the mounting bracket 21 via a bearing seat. The bottom of the moving plate 24 slides on the bottom of the inner side of the mounting bracket 21, which can limit the movement of the moving plate 24. When the threaded rod 23 rotates, it drives the moving plate 24 to move back and forth along the slide rail. The rotating shaft 25 can rotate freely with the tape release, reducing the tape tension and preventing tape breakage or uneven winding. The take-up shaft 26 is fixedly installed on the outer side of the rotating shaft 25 and has an elastic anti-slip layer on its surface. It is used to sleeve the tape roll and can replace the bushing of different specifications according to the inner diameter of the tape roll to adapt to various tape sizes. The support frame 31 has a U-shaped frame structure, providing stable support for the rotating rod 33 and the fixed tube 41. The second drive motor 32 is a geared motor, which is fixedly installed on the outer side of one end of the support frame 31. The output shaft passes through the support frame 31 and is connected to the rotating rod 33. It has high torque output characteristics, which can drive the wire harness to rotate stably. The speed can be adjusted by the controller to adapt to different winding density requirements. The two ends of the rotating rod 33 are supported on the support frame 31 by bearings and are connected to the output shaft of the second drive motor 32 by a key to ensure efficient power transmission. The two synchronous pulleys of the first synchronous pulley 34 are fixedly installed on the two ends of the outer side of the rotating rod 33 by keys. The pulley grooves are adapted to the synchronous belt 35. The tensioning design ensures that there is no slippage during transmission. The synchronous belt 35 is respectively sleeved on the outer side of the two first synchronous pulleys 34 and the corresponding second synchronous pulleys 36. The two synchronous pulleys of the second synchronous pulley 36 are linked to the first synchronous pulleys 34 by the synchronous belt 35. One of them is fixedly installed on the outer side of the fixed tube 41, and the other is installed on the inner side of the support frame 31 by the rotating rod to ensure synchronous rotation at both ends. The fixing tube 41 is made of hollow steel tube and has a guide plane inside that matches the plane of the extension rod 42 to prevent the extension rod 42 from rotating when sliding. The extension rod 42 is a solid round rod that is slidably connected to the inside of the fixing tube 41. Its surface has a scale along the length direction for easy and precise length adjustment. Its end is fixedly connected to the clamping assembly 5 to ensure the stability of the clamping assembly 5 after adjustment. The locking screw 43 is a wing screw that is threaded into the threaded hole at the top of the fixing tube 41 and abuts against the top of the extension rod 42. When tightened, the position of the extension rod 42 can be fixed by friction, which is convenient to operate and reliable. The clamping frame 51 has a U-shaped structure, providing a mounting carrier for the drive telescopic rod 52 and the clamping plate 53. The drive telescopic rod 52 is vertically fixedly installed on the top and bottom of the clamping frame 51, respectively. It adopts a small electric push rod or pneumatic push rod and has an adjustable stroke function, which can adjust the spacing of the clamping plate 53 according to the diameter of the wire harness. The two clamping plates 53 are fixedly installed on the moving end of the drive telescopic rod 52, made of nylon material, with arc-shaped grooves on the surface. Rubber anti-slip pads are pasted in the grooves, which can not only fit tightly against the surface of the wire harness, but also avoid excessive clamping force from damaging the insulation layer of the wire harness, thus achieving the "anti-pull-out" effect.

[0025] The working principle of the electronic wire harness tape anti-pull-out winding device provided by this utility model is as follows: When in use, first adjust the adjusting component 4 according to the length of the wire harness to be wound; loosen the locking screw 43, pull the extension rod 42 to slide inside the fixing tube 41 so that the distance between the two clamping components 5 is adapted to the length of the wire harness, and then tighten the locking screw 43 to fix the extension rod 42. Next, place both ends of the wire harness into the two clamping frames 51 respectively, start the drive telescopic rod 52, drive the telescopic rod 52 to move the clamping plate 53, so that the two clamping plates 53 clamp and fix the two ends of the wire harness to prevent the wire harness from falling off during the winding process; then install the tape roll on the take-up shaft 26, and stick the free end of the tape to the starting position of the wire harness. Start the second drive motor 32, which drives the rotating rod 33 to rotate. The rotating rod 33 drives the two first synchronous pulleys 34 to rotate. The first synchronous pulleys 34 drive the second synchronous pulleys 36 to rotate via the synchronous belt 35. One of the second synchronous pulleys 36 drives the clamping frame 51 connected to it to rotate, and the other second synchronous pulley 36 drives the fixing tube 41 to rotate. The fixing tube 41 drives the other clamping frame 51 to rotate via the extension rod 42, thereby causing the two clamping components 5 to drive the wire harness to rotate together. At the same time, the first drive motor 22 is started, which drives the threaded rod 23 to rotate. The threaded rod 23 drives the moving plate 24 to slide on the mounting bracket 21. The moving plate 24 drives the take-up shaft 26 to move through the rotating shaft 25, so that the tape is evenly wound on the wire harness as the take-up shaft 26 moves. During the winding process, the rotating shaft 25 will rotate as the tape is released to ensure that the tape can be released smoothly.

[0026] Compared with related technologies, the electronic wire harness tape anti-pull-out wrapping device provided by this utility model has the following beneficial effects: By adjusting the settings of component 4, the extension rod 42 in component 4 can slide inside the fixed tube 41 during use. By loosening and tightening the locking screw 43, the distance between the two clamping components 5 can be flexibly adjusted to adapt to electronic wire harnesses of different lengths, thereby improving the applicability of the device.

[0027] Second Embodiment

[0028] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application, which provides an anti-pull-out wrapping device for electronic wire harness tape, the second embodiment of this application proposes another anti-pull-out wrapping device for electronic wire harness tape. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0029] Specifically, the second embodiment of this application provides an electronic wire harness tape anti-pull-out winding device, which differs in that the mounting frame 21 has a sliding groove 6 on its side, a movable frame 7 is slidably connected to the inner side of the sliding groove 6, a limit switch 73 is fixedly installed on one side of the movable frame 7, and the limit switch 73 is located on the other side of the movable plate 24.

[0030] The top of the slide 6 is provided with a movable groove 61, the inner side of the movable groove 61 is slidably connected with a bolt 71, the outer side of the bolt 71 is threadedly connected with a nut 72, and the bottom of the bolt 71 is fixedly installed on the top of the movable frame 7.

[0031] The bottom of the nut 72 abuts against the bottom of the inner side of the mounting bracket 21.

[0032] Limit switch 73 is a contact micro switch with its trigger end facing the other side of the moving plate 24, maintaining a preset safe distance from the moving plate 24. When the moving plate 24 moves to the preset position under the drive of the threaded rod 23, its side will trigger limit switch 73. Limit switch 73 then sends an electrical signal to the control system to realize the shutdown control of the first drive motor 22, thereby accurately limiting the movement range of the moving plate 24 and avoiding excessive movement that could cause the tape to wrap around or the equipment to collide.

[0033] The working principle of the electronic wire harness tape anti-pull-out winding device provided by this utility model is as follows: During use, the travel of the moving plate 24 needs to be adjusted according to the length of the wire harness and the winding requirements. At this time, loosen the nut 72 and push the bolt 71 to slide in the moving groove 61. The bolt 71 drives the moving frame 7 to slide in the sliding groove 6, thereby adjusting the position of the limit switch 73. After the limit switch 73 is adjusted to the appropriate position, tighten the nut 72 to fix the moving frame 7, thereby fixing the position of the limit switch 73. When the movable plate 24 moves under the drive of the threaded rod 23 and touches the limit switch 73, the limit switch 73 sends a signal to control the first drive motor 22 to stop working, and the movable plate 24 stops moving, so as to avoid the movable plate 24 moving too much and causing equipment damage or unqualified winding.

[0034] Compared with related technologies, the electronic wire harness tape anti-pull-out wrapping device provided by this utility model has the following beneficial effects: By setting up the slide 6, the movable frame 7, the limit switch 73, the movable groove 61, the bolt 71 and the nut 72, the position of the limit switch 73 can be adjusted according to actual needs, thereby precisely controlling the moving stroke of the movable plate 24, avoiding excessive movement of the movable plate 24, improving the safety of the device operation and the accuracy of winding, and further enhancing the practicality of the device.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
