This type of equipment is widely used in various fields, including automotive, electrical appliances, and communications. With the growth of electronic systems and the number of wires, the importance of wire harness management has become increasingly prominent.

[0003] Tape winding equipment generally includes two types: point winding and full winding. Point winding equipment is mainly used to bundle a portion of a wire harness. For example, a winding machine disclosed in the Chinese patent publication number CN 217600022 U clamps the wire at both ends by a first clamping device 71 and a second clamping device 72, so that the wire is located in the central through hole 30. The winding drive device 8 drives the rotating seat 3 to rotate around the wire, and the tape 41 is wound around the predetermined area of ​​the wire. However, in this patent, the toothed ring 81 is driven by a toothed belt 82. Since the belt drive is prone to slippage, wrinkles and the like may appear during the tape winding process, making the final winding effect difficult to achieve and the tape may easily fall off.

[0004] In view of this, the inventors propose the following technical solutions. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel tape wrapping mechanism.

[0007] Furthermore, in the above technical solution, the positioning device includes an upper support plate and a lower support plate installed on both sides of the first feeding slot to form a wiring harness positioning slot, wherein a cutter for cutting the tape is provided on the upper support plate or the lower support plate.

[0008] Furthermore, in the above technical solution, the feeding module includes a tape mounting rack installed on a rotating ring and used to install the tape roll, and a guide wheel arranged on one side of the positioning device and used to conduct the tape. The supporting vertical plate is also provided with dynamic balancing blocks symmetrically distributed on both sides of the positioning device with respect to the feeding module.

[0009] Furthermore, in the above technical solution, the traction module includes a support frame arranged on one side of the supporting vertical plate, a guide rail arranged on the support frame, a sliding seat slidably installed on the guide rail, a traction clamp installed on the sliding seat and used to clamp the wiring harness, and a second driving module for driving the traction clamp to move along the guide rail.

[0010] Furthermore, in the above technical solution, a positioning ring groove for installing a positioning rotating ring is provided on the support vertical plate, and a plurality of rollers distributed circumferentially and capable of fitting to the inner ring of the rotating ring are provided inside the positioning ring groove; a second feed slot corresponding to the first feed slot is provided on the support vertical plate.

[0011] Furthermore, in the above technical solution, the first driving module includes a plurality of driven gears mounted on the supporting plate and circumferentially distributed on the periphery of the rotating ring, a driving gear provided on the supporting plate and used to drive the driven gears to rotate, and a first driving device for driving the driving gear to rotate.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] See Figures 1 to 7 The figure shows a novel tape wrapping mechanism, which includes: a support plate 1, a rotating ring 2 rotatably mounted on the support plate 1, a first drive module 3 provided on the support plate 1 and used to drive the rotating ring 2 to rotate, a positioning device 4 provided at the center of the rotating ring 2 and used to clamp and position the wire harness, and a feeding module 5 provided beside the positioning device 4 and used to provide tape. The rotating ring 2 is provided with a first feed slot 20 for clamping the wire harness. The positioning device 4 is provided on the rotating ring 2 to position the wire harness at the center, and the feeding module 5 is provided on the rotating ring 2 to supply tape into the positioning device 4. The rotating ring 2 is driven to rotate by the first drive module 3, so that the tape is continuously wrapped around the wire harness, thereby achieving rapid winding of the wire harness.

[0022] The positioning device 4 includes an upper support plate 41 and a lower support plate 42, which are installed on both sides of the first feeding slot 20 and form a positioning groove for the wire harness. Among them, a cutter 9 for cutting the tape is provided on the upper support plate 41 or the lower support plate 42. By arranging the cutter 9 on the lower support plate 42, when the wire harness is completed with tape wrapping, the tape can be quickly inserted into the cutter 9 for cutting during the removal process, thereby ensuring that the cut end of the tape remains on the lower support plate 42. This allows the wire harness to be quickly taped the next time it is taped, eliminating the need for manual tape application, which is efficient and convenient.

[0023] The feeding module 5 includes a tape mounting frame 51 mounted on the rotating ring 2 and used to mount the tape roll, and a guide wheel 52 provided on one side of the positioning device 4 and used to conduct the tape. The supporting vertical plate 1 is also provided with dynamic balancing blocks 7 symmetrically distributed on both sides of the positioning device 4 with respect to the feeding module 5. By mounting the feeding module 5 on the rotating ring 2 and being located on one side of the positioning device 4, the tape can rotate around the wiring harness as the feeding module 5 rotates with the rotating ring 2, thereby winding the tape onto the wiring harness. Since the feeding module 5 is eccentrically located at some angles of the rotating ring 2, a dynamic balancing block 7 is added on the other side of the rotating ring 2 to balance the centrifugal force generated by the swing of the feeding module 5, thereby avoiding vibration of the feeding module 5 as the rotating ring 2 rotates, making the tape winding process more stable.

[0024] In one embodiment, a pulling module 6 for clamping the wire harness and pulling it toward the other end is provided on one side of the support vertical plate 1. The pulling module 6 includes a support frame 61 provided on one side of the support vertical plate 1, a guide rail 62 provided on the support frame 61, a sliding seat 63 slidably mounted on the guide rail 62, a pulling clamp 64 mounted on the sliding seat 63 and used to clamp the wire harness, and a second driving module 65 for driving the pulling clamp 64 to move along the guide rail 62. In this embodiment, the pulling module 6 clamps one end of the wire harness and pulls the wire harness through the rotating ring 2 continuously when the rotating ring 2 rotates to wrap the tape, thereby achieving continuous winding of the tape along the wire harness. At this time, the machine is stopped to peel off the wire harness that is not wrapped with tape from the rotating ring 2, so that when the tape is continued to be wound, different amounts of wire can be adjusted to wind, so as to meet the problem of not being able to selectively wind wires of different lengths.

[0025] The traction clamp 64 includes a first clamping arm 641 and a second clamping arm 642 mounted on the sliding base 63 for clamping the wiring harness, and a third driving device 643 mounted on the sliding base 63 for driving the first clamping arm 641 and the second clamping arm 642 to open and close. The first clamping arm 641 is fixedly mounted on the sliding base 63 and extends toward the side of the supporting vertical plate 1. The second clamping arm 642 is rotatably mounted on the sliding base 63 and can swing to closely clamp the wiring harness with the first clamping arm 641. The third driving device 643 is a cylinder mounted beside the second clamping arm 642 and fixed to the end of the second clamping arm 642 via a connecting plate 644.

[0026] The second driving module 65 includes a first pulley group 651 arranged parallel to the side of the guide rail 62 and a second motor 652 installed on the support frame 61 and used to drive the first pulley group 651 to drive the sliding seat 63 to move along the guide rail 62, wherein a sensor 653 for stopping the sliding seat 63 is provided at one end of the support frame 61, and the sensor 653 is located on one side of the supporting vertical plate 1, and an induction sheet 654 that can trigger the sensor 653 is provided on the sliding seat 63.

[0027] The support plate 1 is provided with a positioning ring groove 11 for mounting the positioning rotating ring 2. A plurality of rollers 12 are disposed within the positioning ring groove 11 and are arranged circumferentially and adapted to fit the inner ring of the rotating ring 2. The rollers 12 are rotatably mounted on the support plate 1 via a limiting end cap 13. The support plate 1 is also provided with a second feed slot 10 corresponding to the first feed slot 20. By fastening the rotating ring 2 within the positioning ring groove 11 of the support plate 1, the rotating ring 2 can rotate 360° within the positioning ring groove 11. Furthermore, by disposing multiple rollers 12 on one side of the positioning ring groove 11 to contact the inner ring of the rotating ring 2, the rotating ring 2 can rotate more smoothly, with less resistance and friction.

[0028] The first drive module 3 includes a plurality of driven gears 31 mounted on the support plate 1 and circumferentially distributed around the periphery of the rotating ring 2, a driving gear 32 disposed on the support plate 1 and configured to drive the driven gears 31, and a first drive device 33 configured to drive the driving gear 32. A toothed ring portion 21 capable of meshing with the driven gears 31 is disposed on the outer wall of the rotating ring 2, and a plurality of driven gears 31 mesh with the toothed ring portion 21 at intervals. The first drive device 33 includes a first motor 331 configured to drive the driving gear 32, and a second pulley assembly 332 disposed between the first motor 331 and the driving gear 32. A toothed ring portion 21 is provided on the outer wall of the rotating ring 2 to facilitate engagement of the driven gear 31 with the rotating ring 2 to drive its rotation. The engagement of multiple driven gears 31 with the toothed ring portion 21 of the rotating ring 2 for driving not only ensures the center of the rotating ring 2 is free from air, but also ensures the smooth rotation of the rotating ring 2 due to the synchronous meshing of multiple gears, thereby reducing the dynamic balance effect caused by the eccentric layout of the feeding module 5 during rotation and significantly improving the stability of the mechanism. Furthermore, the total number of driven gears 31 is odd, wherein the middle driven gear 31 meshes with the driving gear 32, and the driven gears 31 on both sides of the middle driven gear 31 simultaneously mesh with the toothed ring portion 21 of the rotating ring 2. The two driven gears 31 extending outwardly disengage from the rotating ring 2, and then the two driven gears 31 extending outwardly mesh with the rotating ring 2. The driven gears 31 are sequentially meshed with the rotating ring 2 at intervals, thereby ensuring that the angular velocity transmitted to the rotating ring 2 by the driven gears 31 is consistent in direction.

[0029] A housing 8 is provided on one side of the supporting vertical plate 1, which covers the traction module 6, wherein the traction clamp 64 of the traction module 6 extends out of the housing 8, and the housing 8 is provided with a travel groove 81 for the traction clamp 64 to extend and move back and forth; a control host 82 is provided on the housing 8, and the control host 82 includes a touch screen 821, an emergency stop button 822, a reset button 823, and a controller for controlling the operation of the first drive module 3 and the traction module 6, such as a foot pedal.

[0030] In summary, when the present invention is working, one end of the wiring harness is placed into the positioning device 4, and the wiring harness is adhered to the tape pulled out from the feeding module 5, and then the end of the wiring harness is clamped by the traction module 6; further, by stepping on the pedal to control the first driving module 3 to start driving the rotating ring 2 to rotate, the tape is wound onto the wiring harness, and at the same time the traction module 6 pulls the wiring harness to move to the other side, so that the tape is gradually wound around the entire wiring harness; further, when it is necessary to adjust the number of wound wires in the wiring harness, the part of the wire that does not need to be wound can be wound by stopping the machine. Take out the rotating ring 2, and then restart the first drive module 3 and the traction module 5. At this time, the tape will only be wrapped around the remaining wiring harness, so that the number of wound wiring harnesses can be quickly adjusted. Of course, the number of wound wires in the wiring harness can be adjusted multiple times during the winding process to meet different needs, especially for products such as automobiles that require a large number of wiring harnesses. The main wiring harness needs to separate some wires at different distances, and different areas use different wire lengths. Therefore, the number of windings of the wiring harness needs to be adjusted differently to ensure that the wiring harness routing is simpler and clearer.

[0031] After adopting the above scheme, the utility model has the following effects:

[0032] 1. The whole machine is compact and the winding mechanism is more reasonable;

[0033] 2. It takes up little space, has little vibration, reduces noise, is easy to operate, does not require lubrication every shift, and is less likely to get dirty, making it easy to maintain.

[0034] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
