Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically a tooling for rapid wire harness manufacturing. Background Technology

[0002] In the automotive, electronics, and industrial control fields, wire harnesses serve as the core carriers of signal and power transmission, and their processing quality directly determines the operational stability and safety of terminal equipment. Tape wrapping is a crucial step in wire harness processing to achieve protection and structural fixation. Utilizing the insulation, abrasion resistance, and anti-interference properties of the tape substrate, combined with specific wrapping techniques, wire harnesses composed of multiple conductors are wrapped. This not only isolates adjacent conductors and blocks moisture and dust through insulating substrates such as PVC and acetate cloth to ensure electrical performance, but also resists friction damage with the help of high-strength substrates such as neoprene rubber and PET. Some shielding tapes can also achieve electromagnetic interference shielding.

[0003] Currently, this process in the industry generally relies on manual operation. Operators need to hold tape and manually wrap the wire harness according to the position, spacing, and overlap rate required by the drawings. However, this method has obvious drawbacks: the manual wrapping speed is greatly affected by skill level and physical strength, and it takes a long time to process long-length, multi-branch wire harnesses, with efficiency far lower than that of automated processes; moreover, manual operation is prone to uneven wrapping overlap rate, tape wrinkling, or missed wrapping due to fatigue and attention deviation, affecting the protective effect and the consistency of the wire harness; at the same time, when switching between different specifications of wire harnesses, the operator needs to readjust the rhythm, resulting in low production line switching efficiency and difficulty in meeting the needs of large-scale modern production.

[0004] Therefore, this utility model provides a tooling for rapid fabrication of wire harnesses. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a tooling for rapid wire harness manufacturing, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for rapid wire harness fabrication, comprising a base and a clamp. A support ring is provided at the top of the base, and a rotating ring is rotatably connected to the inner wall of the support ring. Baffles are detachably connected to both sides of the rotating ring, and a roll of adhesive tape is installed between the two baffles. A vertical rod is installed at the top of the base, and a rotating frame is rotatably connected to one side of the vertical rod. Two transmission rods are installed on one side of the rotating frame, and the rotating ring is slidably connected to the side walls of the two transmission rods. A screw is rotatably connected to one side of the vertical rod. A sliding support is installed at the bottom of the support ring, and the sliding support is slidably connected to the top of the base. The screw is threadedly connected to the inner wall of the sliding support.

[0007] Preferably, the base has two rails installed at its top, and the sliding support has two notches at its bottom corresponding to the positions of the rails. The sliding support is slidably connected to the outside of the two rails.

[0008] Preferably, the inner side of the support ring is provided with an annular inner groove, and a limit ring is installed on the outer side of the rotating ring, the limit ring being rotatably connected to the inner wall of the annular inner groove.

[0009] Preferably, a plurality of connecting rods are installed on one side of the rotating ring, and a tightening ring is installed between the plurality of connecting rods, and an expansion port is provided on one side of the tightening ring.

[0010] Preferably, the base extends upward from the end away from the upright, and the screw is rotatably connected to the side wall of the base extension area.

[0011] Compared with the prior art, the present invention has the following advantages: By coordinating components such as support rings, rotating rings, rotating frames, and screws, automated tape winding is achieved, completely eliminating reliance on manual skill and physical strength, and significantly improving the processing efficiency of long, multi-branch wire harnesses. Precise transmission driven by a motor ensures uniform tape overlap and prevents wrinkling or missed wrapping during the winding process, significantly improving the wire harness protection effect and product consistency. This effectively solves problems such as low efficiency, poor quality stability, and slow production line changeover associated with manual winding, meeting the needs of large-scale modern production.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 A tooling for rapid wire harness fabrication includes a base 1 and a clamp 11. A support ring 2 is provided at the top of the base 1, and a rotating ring 3 is rotatably connected to the inner wall of the support ring 2. Baffles 31 are detachably connected to both sides of the rotating ring 3, and a roll of tape 32 is installed between the two baffles 31. A vertical rod 4 is installed at the top of the base 1, and a rotating frame 41 is rotatably connected to one side of the vertical rod 4. Two transmission rods 42 are installed on one side of the rotating frame 41. The rotating ring 3 is slidably connected to the side wall of the two transmission rods 42. A screw 43 is rotatably connected to one side of the vertical rod 4. A sliding support 22 is installed at the bottom of the support ring 2, and the sliding support 22 is slidably connected to the top of the base 1. The screw 43 is threadedly connected to the inner wall of the sliding support 22.

[0016] Specifically, during operation, first operate the clamp 11 to open the cover plate, place the end of the wire harness to be processed into the clamping cavity, and close the cover plate to achieve a stable clamping of the wire harness, ensuring that the wire harness does not shift during the winding process. The support ring 2 provides stable support for the rotating ring 3, and the tape roll 32 is fixed in the rotating ring 3 by the detachably connected baffle 31. The free end of the tape is pulled out and its initial end is pasted to the position where the wire harness is to be wound. Subsequently, the dual-motor drive system on one side of the upright 4 is activated: one motor drives the rotating frame 41 to rotate, and the rotating frame 41 transmits torque through two transmission rods 42 that pass through the rotating ring 3, causing the rotating ring 3 to rotate stably around the wire harness axis. The tape roll 32 rotates synchronously with the rotating ring 3, realizing the wrapping of the wire harness with tape; the other motor drives the screw 43 to rotate. Since the screw 43 is threadedly connected to the sliding support 22 fixed at the bottom of the support ring 2, and the sliding support 22 is slidably engaged with the top of the base 1, under the helical thrust of the screw 43, the support ring 2 drives the rotating ring 3 and the tape roll 32 to move uniformly away from the upright 4 along the length of the wire harness, forming a uniform spiral winding trajectory in conjunction with the rotation. By setting the motor parameters, the rotation speed of the rotating ring 3 and the moving speed of the sliding support 22 can be precisely controlled, thereby ensuring that the overlap rate, spacing and other parameters of the tape winding are stable and consistent, without the need for manual re-familiarization with the operating rhythm.

[0017] In one embodiment of this utility model, such as Figures 1-4 As shown, two rails 12 are installed at the top of the base 1, and two notches corresponding to the positions of the rails 12 are opened at the bottom of the sliding support 22. The sliding support 22 is slidably connected to the outside of the two rails 12.

[0018] Specifically, the two track bars 12 at the top of the base 1 are adapted to the notches at the bottom of the sliding support 22 to form a sliding guide structure. When the screw 43 drives the sliding support 22 to move, the track bars 12 are embedded in the notches of the sliding support 22, providing precise guidance for the sliding of the sliding support 22, restricting it to only move in a straight line along the length of the wire harness during the movement, and avoiding deviation, swaying and other situations.

[0019] In one embodiment of this utility model, such as Figures 1-4 As shown, an annular inner groove 21 is provided on the inner side of the support ring 2, and a limit ring 33 is installed on the outer side of the rotating ring 3. The limit ring 33 is rotatably connected to the inner wall of the annular inner groove 21.

[0020] Specifically, the annular inner groove 21 on the inner side of the support ring 2 and the limiting ring 33 on the outer side of the rotating ring 3 form a rotating fit structure. The limiting ring 33 is embedded in the annular inner groove 21 and can rotate freely along the groove. It not only provides radial limiting for the rotating ring 3 to prevent it from shifting or shaking during rotation, but also does not hinder the circumferential rotation of the rotating ring 3, ensuring that the rotating ring 3 drives the tape roll 32 to rotate stably around the wire harness axis.

[0021] In one embodiment of this utility model, such as Figures 1-4 As shown, a number of connecting rods 34 are installed on one side of the rotating ring 3, and a tightening ring 35 is installed between the connecting rods 34. An expansion port 351 is provided on one side of the tightening ring 35.

[0022] It should be noted that the expansion port 351 described in this embodiment facilitates the wire harness to pass through the tightening ring 35. When the tightening ring 35 slides, it can straighten the wire harness, which is convenient for subsequent winding.

[0023] Specifically, the expansion port 351 on one side of the tightening ring 35 provides a guide for the wire harness to enter, facilitating the smooth entry of the wire harness into the tightening ring 35. When the tooling drives the rotating ring 3 and related components to move and wind, the tightening ring 35 will slide along the length of the wire harness, using its own structural characteristics to straighten any bent or twisted wire harness, keeping the wire harness in a straight state.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, the end of the base 1 away from the upright 4 extends upward, and the screw 43 is rotatably connected to the side wall of the extension area of ​​the base 1.

[0025] Specifically, the end of the base 1 away from the upright 4 extends upward to form an extension area. One end of the screw 43 is rotatably connected to one side of the upright 4, and the other end is rotatably connected to the side wall of the extension area, so that the screw 43 forms a stable installation structure with two-end support at the top of the base 1, thereby ensuring that the sliding support 22 threadedly connected to the screw 43 can move smoothly along the axis of the screw 43, driving the support ring 2, the rotating ring 3 and the tape roll 32 to move at a uniform speed along the length of the wire harness.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: When this fixture is in operation, the end of the wire harness is first fixed by the clamp 11. The tape roll 32 is installed in the rotating ring 3 through the baffle 31, with the initial end of the tape attached to the wire harness. The dual-motor drive system is started. One motor drives the rotating frame 41, which rotates the rotating ring 3 around the wire harness through the transmission rod 42, achieving tape wrapping. The other motor drives the screw 43, which engages with the sliding support 22, pushing the support ring 2 and the rotating ring 3 to move at a uniform speed along the length of the wire harness, forming a uniform spiral winding. The track bar 12 of the base 1 engages with the notch of the sliding support 22 to ensure smooth movement. The annular inner groove 21 of the support ring 2 engages with the limiting ring 33 of the rotating ring 3 to ensure rotational stability. The tightening ring 35 on one side of the rotating ring 3 guides the wire harness through the expansion port 351, straightening the wire harness during movement. The two ends of the screw 43 are connected to the upright 4 and the extension area of ​​the base 1, respectively, forming a stable support. By setting motor parameters to control winding parameters, and by changing the cover plate of clamp 11 and adjusting parameters, different wire harnesses can be adapted to achieve automated and precise tape winding, thereby improving efficiency and quality stability.
