[0034] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] Please see Figures 1 to 5The automatic tape wrapping mechanism for wire harness assembly provided by this utility model will now be described. The automatic tape winding mechanism for assembling wire harnesses includes a worktable 10, a wire harness clamping mechanism 20, a tape mounting mechanism 30, and a wire harness finishing mechanism 40. The wire harness clamping mechanisms 20 are arranged in pairs at both ends of the worktable 10. Each wire harness clamping mechanism 20 includes a clamping claw 21 arranged along the length of the worktable 10. The clamping claw 21 is used to clamp the end of the wire harness 11 to be wound and drive the wire harness 11 to be wound to rotate. The tape mounting mechanism 30 is movably mounted on the worktable 10 along the length of the worktable 10. The tape mounting mechanism 30 is equipped with a tape roll 31 and a cutting component. The cutting component is used to cut the tape and leave the tape tail end outside the wire harness 11 to be wound. The wire harness finishing mechanism 40 moves synchronously with the tape mounting mechanism 30. The wire harness finishing mechanism 40 includes an openable clamping claw 41. The clamping claw 41 clamps the tail end of the wire harness 11 to be wound so that the tape tail end is wrapped and attached to the tail end of the wire harness 11 to be wound.

[0036] First, the wire harness 11 to be wrapped is clamped by the clamping claws 21 of the wire harness clamping mechanism 20 and rotated. The tape roll 31 moves horizontally backward with the tape installation mechanism 30. During the movement, the tape is wrapped around the outside of the wire harness. After the wrapping is completed, the tape is cut by the shearing component. There is a certain gap between the shearing component and the wire harness, so that a section of tape is left at the end of the wire harness after cutting. The clamping claws 41 are attached to the outside of the wire harness and rotate with the wire harness to attach the tape end to the wire harness.

[0037] The automatic tape winding mechanism for wire harness assembly provided by this utility model adopts a passive tape winding method compared with the prior art, which has high winding efficiency, low manual labor intensity, and can adjust the winding speed and winding effect of the wire harness at any time by changing the moving speed of the tape and the rotation speed of the wire harness. It has high winding stability and can achieve uniform tape coverage and spacing. In addition, the design of the clamping claw 41 can achieve the effect of manual finishing.

[0038] The automatic tape wrapping mechanism for wire harness assembly achieves automated tape wrapping, replacing manual tape wrapping. This reduces labor intensity and saves manpower; the wrapping efficiency is 4-5 times that of manual wrapping. The automatic tape wrapping mechanism can achieve a tighter and more even tape coverage than manual wrapping, reducing the need for repeated wrapping and thus saving nearly one-third of the tape raw materials.

[0039] There are two wire harness clamping mechanisms 20, which are symmetrically installed at both ends of the workbench 10 along its length. The two wire harness clamping mechanisms 20 are respectively a first wire harness clamping mechanism 20 and a second wire harness clamping mechanism 20. The first wire harness clamping mechanism 20 and the second wire harness clamping mechanism 20 are arranged opposite each other and have a certain interval. The area of ​​the workbench 10 between the first wire harness clamping mechanism 20 and the second wire harness clamping mechanism 20 is the working area of ​​the tape installation mechanism 30.

[0040] The first wire harness clamping mechanism 20 is located at the end of the workbench 10, and the second wire harness clamping mechanism 20 is located in the middle or at the other end of the workbench 10; the working direction of the tape mounting mechanism 30 is the direction of movement from the first wire harness clamping mechanism 20 toward the second wire harness clamping mechanism 20, that is, the first wire harness clamping mechanism 20 is located on the front side, and the second wire harness clamping mechanism 20 is located on the rear side.

[0041] The extension direction of the jaws of the wire harness clamping mechanism 20 is consistent with the length direction of the worktable 10. The jaws of the two wire harness clamping mechanisms 20 are arranged opposite each other to clamp two parts of the same wire harness. The part of the wire harness located between the jaws of the two wire harness clamping mechanisms is the wire harness 11 to be wound.

[0042] In some possible embodiments, please refer to Figures 1 to 3 The wire harness clamping mechanism 20 includes a clamping mechanism mounting plate 25 and a rotary motor 22. The clamping mechanism mounting plate 25 is fixed on the worktable 10, and the rotary motor 22 is mounted on the clamping mechanism mounting plate 25. The output end of the rotary motor 22 is connected to the fixed end of the wire clamping claw 21 and is used to drive the wire clamping claw 21 to rotate. The independent drive of the wire clamping claw 21 by the rotary motor 22 can realize the control of the rotation speed of the wire harness 11 to be wound, so that the rotation speed of the wire harness 11 to be wound matches the moving speed of the tape mounting mechanism 30.

[0043] The clamping mechanism mounting plate 25 of the wire harness clamping mechanism 20 is mounted on the workbench 10. The clamping mechanism mounting plate 25 is horizontally positioned. A rotary motor 22 is mounted on the upper end of the clamping mechanism mounting plate 25. One end of the clamping mechanism mounting plate 25 has an end plate for mounting a clamping button. The clamping button is electrically connected to the wire clamping claw 21 to control the opening and closing of the wire clamping claw 21. The output end of the rotary motor 22 passes through the end plate and extends to the tail end of the wire clamping claw 21, driving the wire clamping claw 21 to rotate the wire harness 11 to be wound.

[0044] A housing structure is installed on the upper end of the mounting plate to cover and protect the rotary motor 22. To facilitate the rotation of the wire harness 11 to be wound and the normal operation of the tape installation mechanism 30, there is a gap between the wire clamping claw 21 and the upper surface of the worktable 10, so that a gap is left between the wire harness 11 to be wound and the worktable 10.

[0045] Optionally, at least one wire harness clamping mechanism 20 has a degree of freedom along the length direction of the worktable 10.

[0046] Taking a wire harness clamping mechanism 20 having a degree of freedom along the length of the worktable 10 as an example: the first wire harness clamping mechanism 20 is fixedly connected to the worktable 10, and the second wire harness clamping mechanism 20 is horizontally movable on the worktable 10. A limiting plate 23 is provided on the rear side of the second wire harness clamping mechanism 20, and the limiting plate 23 is fixedly installed on the worktable 10. The clamping mechanism mounting plate 25 of the second wire harness clamping mechanism 20 is slidably disposed on the worktable 10, and a telescopic member 24 is provided between the clamping mechanism mounting plate 25 and the limiting plate 23 of the second wire harness clamping mechanism 20. The telescopic member 24 can be a cylinder or an electric push rod.

[0047] Specifically, the upper panel of the worktable 10 has a groove-shaped structure with a downward recess in the middle. The two sides of the worktable 10 are slidably connected to the worktable 10, with a gap left between the middle part and the worktable 10. The two ends of the telescopic member 24 are respectively connected to connecting blocks, and both ends of the telescopic member 24 are fixed to the bottom end of the limiting plate 23 and the bottom end of the clamping mechanism mounting plate 25 of the second wire harness clamping mechanism 20 by means of connecting blocks.

[0048] By moving the second wire harness clamping mechanism 20 laterally, the distance between the two wire harness clamping mechanisms 20 can be adjusted, thereby changing the tape winding length.

[0049] In some possible embodiments, please refer to Figure 2 , Figure 6 and Figure 7 The tape installation mechanism 30 is movably mounted on the workbench 10 by means of the moving mechanism 50. The moving mechanism 50 includes a moving frame 58, a moving gear 52, and a rack 53. The rack 53 is mounted on the lower end of the edge of the workbench 10. The moving frame 58 is slidably mounted on the edge of the workbench 10. The lower end of the moving frame 58 extends to the lower part of the rack 53. The moving gear 52 is mounted on the moving frame 58. The moving gear 52 meshes with the rack 53. The rotation of the moving gear 52 drives the moving frame 58 to move horizontally. The tape installation mechanism 30 is located on the moving frame 58.

[0050] The movable frame 58 of the movable mechanism 50 is located on the side of the workbench 10, with its upper end extending above the workbench 10 and its lower end extending below the workbench 10. The upper end of the movable frame 58 slides against the edge of the workbench 10. A limiting roller 54 is also installed on the upper part of the movable frame 58. The limiting roller 54 is in contact with the smooth surface of the upper end of the rack 53. The limiting roller 54 and the movable gear 52 are clamped at the upper and lower ends of the rack 53, ensuring the meshing of the movable gear 52 with the rack 53. This also improves the working stability of the movable frame and allows for real-time adjustment of the moving speed of the tape installation mechanism 30.

[0051] The movable gear 52 is connected to the drive motor 55, and the drive motor 55 and the movable gear 52 are coaxially arranged. When the drive motor 55 rotates forward or backward, it drives the movable gear 52 to move forward or backward, thereby driving the tape mounting mechanism 30 to move forward or backward.

[0052] In another embodiment, such as Figure 7 As shown, a drive motor 55 is mounted on the movable frame 58. The drive motor 55 and the moving gear 52 are connected by a transmission assembly, which includes a driving gear 56, a driven gear 57, and a toothed belt. The driving gear 56 is connected to the output shaft of the drive motor 55. The driven gear 57 is coaxially arranged with the moving gear 52 and rotates synchronously. The driven gear 57 and the driving gear 56 are located in the same longitudinal plane and are connected by a toothed belt.

[0053] To save installation space, a moving gear 52 is installed at the lower part of the movable frame 58, and a drive motor 55 is installed at the upper part of the movable frame 58, with the output shaft of the drive motor 55 located above the moving gear 52. The drive motor 55 drives the moving gear 52 through a transmission assembly.

[0054] The drive motor 55 is fixed to the outside of the movable frame 58, and its output end extends into the movable frame 58. The output end of the drive motor 55 is connected to the drive gear 56. The driven gear 57 is coaxially mounted on the movable gear 52, and the driven gear 57 is located below the drive gear 56. The drive gear 56 and the driven gear 57 mesh or are connected by a toothed belt.

[0055] The tape mounting mechanism 30 is connected to the moving mechanism 50 to achieve horizontal movement, while the line finishing mechanism 40 moves synchronously with the tape mounting mechanism 30. The line finishing mechanism 40 is connected to the tape mounting mechanism 30 or to the moving mechanism 50 to achieve synchronous movement.

[0056] like Figures 1 to 2 To facilitate the finishing work of the entire line and save installation space, the finishing mechanism 40 and the tape installation mechanism 30 are symmetrically arranged on both sides of the line connecting the two pairs of wire clamping claws 21, that is, the finishing mechanism 40 and the tape installation mechanism 30 are respectively located on both sides of the wire harness 11 to be wrapped.

[0057] Taking the example where both the production line finishing mechanism 40 and the tape installation mechanism 30 are connected to the moving mechanism 50.

[0058] There are two moving mechanisms 50, symmetrically arranged on both sides of the workbench 10. The upper ends of the two moving frames 58 are connected and fixed by a transverse top plate 51. The line finishing mechanism 40 is located on the transverse top plate 51. The upper ends of the moving frames 58 of both moving mechanisms 50 protrude above the workbench 10. The two moving mechanisms 50 are connected by the transverse top plate 51, which is located in the gap between the wire harness 11 to be wound and the upper surface of the workbench 10. There is a gap between the upper end of the transverse top plate 51 and the wire harness 11 to be wound, and a gap between the lower end of the transverse top plate 51 and the upper surface of the workbench 10. The arrangement of the two moving mechanisms 50 further ensures the moving stability of the tape installation mechanism 30, facilitates the installation of the line finishing mechanism 40, and saves installation space.

[0059] The tape installation mechanism 30 is installed on the movable frame 58, and the wire finishing mechanism 40 is installed on the horizontal top plate 51. The working ends of the tape installation mechanism 30 and the wire finishing mechanism 40 are arranged opposite to each other and are located on both sides of the same wire bundle 11 to be wrapped.

[0060] like Figure 4 As shown, the tape finishing mechanism 40 includes a mounting frame and a clamping cylinder. The mounting frame is fixed to the transverse top plate 51, and the clamping cylinder is connected to the mounting frame. The end of the clamping cylinder is connected to a clamping jaw 41. When the tape installation mechanism 30 is working, the clamping jaw 41 is in an open state, with its two jaws positioned above and below the wire harness 11 to be wrapped, respectively. When the tape installation mechanism 30 finishes working, the shearing component cuts the tape, and the clamping cylinder drives the clamping jaw 41 to close. The two jaws of the clamping jaw 41 then adhere to the upper and lower ends of the wire harness 11 to be wrapped, respectively. As the wire harness 11 rotates, the clamping jaw 41 assists in finishing the cut end of the tape, ensuring it smoothly adheres to the end of the wire harness 11. The clamping cylinder has a pneumatic valve.

[0061] like Figure 4 and Figure 5 As shown, the tape mounting mechanism 30 includes a base plate 32 and a tape mounting bracket. The base plate 32 is fixed to the movable frame 58, and the tape mounting bracket is longitudinally fixed to the base plate 32 for connecting the tape roll 31. The shearing component is located on the base plate 32 and has horizontal freedom. Both the shearing component and the tape mounting bracket are fixed to the base plate 32, ensuring the length of the cut tape tail end and improving the appearance of the tape bonding.

[0062] The base plate 32 is mounted on the movable frame 58 and is used to support the tape mounting bracket and the shearing parts. The upper part of the tape mounting bracket is rotatably connected to the mounting rollers, and the tape roll 31 is sleeved on the mounting rollers; the axial direction of the mounting rollers is at an angle to the length direction of the worktable 10 so that the tape and the wire bundle 11 to be wrapped form a certain angle.

[0063] The shearing assembly includes a telescopic cylinder 34, a fixing frame, and scissors 33. The telescopic cylinder 34 is horizontally mounted on the base plate 32. The fixing frame connects to the movable end of the telescopic cylinder 34 and is used to fix the scissors 33. The moving direction of the telescopic cylinder 34 is consistent with the length direction of the scissors 33, and the direction of the scissors 33 is consistent with the width direction of the tape. Pneumatic scissors 33 are selected.

[0064] In some possible embodiments, please refer to Figure 1 and Figure 2 The wire harness clamping mechanism 20 has two sets of wire clamping claws 21, which are spaced apart along the width of the workbench 10. Correspondingly, there are two sets of tape mounting mechanism 30 and two sets of wire finishing mechanism 40. The two sets of tape mounting mechanism 30 are symmetrically arranged on the outside of the two sets of wire clamping claws 21, and the two sets of wire finishing mechanism 40 are symmetrically arranged between the two sets of wire clamping claws 21.

[0065] The grippers have two sets in the width direction of the worktable 10, and each set of grippers is connected to a rotary motor 22, which can rotate independently.

[0066] Two sets of tape installation mechanisms 30 are located on the movable frames 58 on both sides of the workbench 10 or mounted on the horizontal top plate 51. The tape installation mechanisms 30 are located outside the two wire bundles 11 to be wrapped, and the working ends of the tape installation mechanisms 30 are arranged opposite each other. Two sets of wire wrapping mechanisms 40 are mounted on the horizontal top plate 51 between the two wire bundles 11 to be wrapped, and the two sets are arranged back to back, so that the two clamping claws 41 face outwards and are opposite to their corresponding tape installation machines. The two sets of wire bundles 11 to be wrapped are arranged horizontally at intervals and can be wrapped simultaneously, which greatly improves the wrapping efficiency.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
