Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to an automatic wire harness wrapping device for automobiles. Background Technology

[0002] Automotive wiring harnesses are the "neural network" of circuits. As the level of automotive electronics increases, the number of wiring harnesses has increased from hundreds to thousands, and the structure has become more complex. Moreover, the wiring harnesses are distributed in different areas such as the engine compartment and chassis, and face diverse environments such as high temperature, oil, mud and water. This has driven the application and upgrading of wrapping tape.

[0003] Currently, cross-linked polyethylene insulated power cables and cable accessories are mostly wrapped manually. Manual wrapping is difficult to control precisely, easily leading to problems such as wrinkles, air bubbles, or insufficient overlap in the tape, resulting in a high product defect rate. Some existing products can only be wrapped with a single type of tape, resulting in low wrapping efficiency. Furthermore, when there are significant differences in wire harness size, different wrapping equipment must be used, significantly reducing production efficiency and costs.

[0004] Therefore, an automatic wiring harness wrapping device for automobiles is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 5 One embodiment of the present invention is provided: The present invention is mainly composed of a base 1 and a support frame 2. The bottom of the base 1 and the support frame 2 are fixedly connected to form a stable overall structure, providing a solid foundation for the stable operation of the equipment.

[0034] In the transmission and adjustment system of the equipment, the internal gear ring 3 of the planetary gear set is fixedly connected inside the support frame 2. The internal gear ring 3 meshes with several planetary gears 4. A sealing ring 6 is fixedly connected to one side of each planetary gear 4, and the planetary gear 4 passes through the sealing ring 6 and is fixedly connected to the connecting shaft 7, so that the connecting shaft 7 can move synchronously with the planetary gears 4. An adjustment groove 51 is opened inside the connecting shaft 7, and an adjustment spring 33 is fixedly connected to one end of it. An adjustment ring 10 is slidably connected inside the adjustment groove 51, and the adjustment ring 10 forms a rotational contact with the fixed column 11. The other end of the fixed column 11 is integrally fixedly connected to the outer wall of the fixed housing 12, which enhances the overall structure. At the same time, an auxiliary support column 13 is slidably connected inside the fixed column 11, which further improves the stability of the equipment during operation. The other end of the adjustment spring 33 is fixedly connected to the fixed column 11, ensuring that the adjustment ring 10 can be firmly locked in the recess of the adjustment groove 51, improving the stability of the equipment during operation.

[0035] The winding motor 14 is fixedly connected inside the fixed housing 12. The trigger end block 23 of the cutting assembly 9 is also slidably connected to the inner wall of one side. The output end of the winding motor 14 is fixedly connected to the lead screw 15. The fixed end winding slider 16 of the winding assembly 8 is rotatably connected to the lead screw 15. The winding action is precisely controlled by the motor drive.

[0036] Reference Figures 5 to 8 The tape winding assembly 8 includes a tape winding slider 16, a tape winding shaft 18, a tape 19, a partition 20, a tension roller bracket 21, and a tension roller 22. The tape winding slider 16 is slidably connected within a tape winding groove 17 located inside the fixed housing 12, ensuring smooth movement of the tape 19 during the tape winding process. The tape winding shaft 18 is fixedly connected to one end face of the tape winding slider 16, and the tape 19 is rotatably connected to the tape winding shaft 18, facilitating the tape winding operation. A partition 20 is fixedly connected near the end of the tape winding shaft 18, and a tension roller bracket 21 is fixedly connected to one side of the partition 20, with a tension roller 22 rotatably connected to the bracket, which can effectively adjust the tension of the tape 19 during the tape winding process, ensuring that the tape 19 is tightly and evenly wound.

[0037] The tape cutting assembly 9 consists of components such as a locking block 23 and a cutter 27. Both ends of the locking block 23 are provided with wedge-shaped surfaces, which are slidably connected in a connecting slot 24 opened on one side of the fixed housing 12. The connecting slot 24 is located close to the tape winding motor 14 to ensure that the equipment can perform tape winding work on wire harnesses 41 of various specifications. A fixing block 25 is fixedly connected to the outer wall of the fixed housing 12, and a return spring 26 is fixedly connected in the connecting slot 24. The other end of the spring is fixedly connected to the locking block 23 to provide power for the reset of the locking block 23. One wedge-shaped surface of the locking block 23 slides in contact with the tape winding slider 16, while the other wedge-shaped surface slides in contact with the cutter 27. The cutter 27 has a blade at one end facing the partition 20 for cutting the tape winding 19. The cutter 27 also has a cutter groove 28 inside, and a cutter guide post 29 is fixedly connected inside the groove. A second return spring 30 is sleeved on the outer wall of the guide post. One end of the second return spring 30 is fixedly connected to the inner wall of the cutter groove 28, and the other end is fixedly connected to the fixing block 25, ensuring that the cutter 27 can smoothly return to its original position after cutting.

[0038] refer to Figure 5 To ensure the stability of the lead screw 15 transmission, a coupling 31 is fixedly connected to the output end of the tape winding motor 14. The other end of the coupling 31 is fixedly connected to the lead screw 15, and the other end of the lead screw 15 is fixedly connected to the bearing seat 32. The bearing seat 32 is fixedly connected to the inner wall of the tape winding groove 17, forming a stable transmission support. An auxiliary fixing post 34 is slidably connected near the edge of the tape winding slider 16. The auxiliary fixing post 34 is fixedly connected inside the tape winding groove 17, further improving the stability of the tape winding slider 16 during sliding.

[0039] refer to Figure 1 and Figure 8 Regarding the stability of the wire harness 41, several roller brackets 35 are fixedly connected to the support frame 2. Roller grooves 36 are provided in the brackets, and roller sliders 37 are slidably connected in the grooves. The piston of the cylinder 38 is fixedly connected to the bottom end of the roller slider 37. The cylinder 38 drives the slider to move up and down. A fixed shaft 39 is fixedly connected to one side of the roller slider 37. A stabilizing roller 40 is rotatably connected to the fixed shaft 39. The wire harness 41 is rotatably connected between the stabilizing rollers 40, which can effectively fix the position of the wire harness 41 and prevent the wire harness 41 from shifting during the winding process of the tape 19.

[0040] refer to Figures 1 to 4Planetary gear 4 meshes with sun gear 5. Seals 43 and 44 are fixedly connected to the outer walls of the internal rack and both sides of sun gear 5, providing sealing protection. A sealing ring 6 is rotatably connected inside seal 44 to ensure that the transmission between gears is not affected by dust or other factors. A drive motor 42 is also fixedly connected to the support frame 2. The output end of the drive motor 42 passes through seal 43 and is fixedly connected to a drive gear 45. The drive gear 45 meshes with sun gear 5, driving the entire planetary gear set through the drive motor 42.

[0041] Both sides of the base 1 are fixedly connected to a fixed seat 46. The fixed seat 46 has a clamping groove 47. A clamping slider is slidably connected in the groove. A bidirectional screw 48 is fixedly connected in the clamping groove 47. The position of the clamping slider can be adjusted by rotating the screw. A clamping post 49 is rotatably connected to the clamping slider. The wire harness 41 is clamped between the clamping blocks 50. The wire harness 41 is further fixed from both ends to ensure the accurate operation of the wrapping tape 19.

[0042] refer to Figures 5 to 6 The corner of the partition 20 is designed to be curved, and the part of the back of the cutter 27 that contacts the partition 20 is also designed to be curved. This structural design can make the cutting action smoother and avoid unnecessary damage to the wrapping tape 19.

[0043] Working principle: When the tape winding starts, the drive motor 42 drives the drive gear 45 to rotate. The drive gear 45 meshes with the sun gear 5, causing the planetary gear set to rotate. The planetary gear 4 drives the connecting shaft 7, the fixed housing 12 and other components to move, so that the tape winding mechanism can rotate around the wire harness 41.

[0044] The adjusting ring 10 slides within the adjusting groove 51, causing the fixed housing 12 to drive the winding tape 19 to move along the axial direction of the wire harness 41. The positions of the adjusting rings 10 on different planetary gears 4 can be consistent or inconsistent to achieve composite winding or single-layer winding of the tape. Different tapes, such as insulating tape and wear-resistant tape, can be installed on different planetary gears 4 to meet the multiple winding requirements of the wire harness 41. The winding motor 14 drives the lead screw 15 to rotate, thereby driving the winding slider 16 to move up and down. The winding sliders 16 on multiple planetary gears 4 move synchronously to enable the equipment to wind wire harnesses 41 of different specifications.

[0045] When the wrapping is complete, the wrapping slider 16 touches the locking block 23 of the cutting assembly 9. The locking block 23 pushes the cutter 27 towards the partition 20 through the wedge surface, cutting the wrapping tape 19 with the blade. Then, the first reset spring 26 and the second reset spring 30 respectively drive the locking block 23 and the cutter 27 to reset, completing one wrapping operation.

[0046] The clamping sliders of the fixing seats 46 on both sides of the base 1 are adjusted in position under the action of the bidirectional screw 48, and the clamping column 49 fixes the wire harness 41 from both ends. At the same time, the stabilizing roller 40 on the support frame 2 is driven by the cylinder 38 to further fix the wire harness 41 and prevent the wire harness 41 from shifting during the wrapping operation.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
