Description

Technical Field

[0001] This utility model relates to the field of wire harness winding technology, and in particular to a tape unwinding and recycling mechanism and a wire harness tape winding device. Background Technology

[0002] Wire harness winding technology has gradually developed alongside the advancements in electrical equipment and electronics. In the early days of electrical equipment development, people began experimenting with simple bundling and winding of wires to achieve electrical connections and fixation. With the development of industrial automation and the increasing demands for electrical control in various products and equipment, the number of wires inside machines has grown rapidly. To achieve centralized management and wiring of multiple wires and reduce the inconvenience caused by scattered wires to equipment structure and subsequent operations, wire harness winding technology has been more widely applied and developed. Simultaneously, the development of the automotive industry has also greatly promoted the progress of wire harness winding technology. With continuous technological advancements, CNC technology and computer technology have gradually been applied to wire harness winding equipment. Winding machines have evolved from manual operation to automated and intelligent control, improving winding efficiency and precision, meeting the winding needs of different types of wire harnesses, and enabling complex winding processes.

[0003] Most current wire harness winding equipment can only use ordinary adhesive tape. Ordinary tape requires a relatively high peel force, making it prone to unsuccessful peeling and leading to winding failure. Compared to ordinary adhesive tape, release paper tape has the advantage of being easier to peel. However, release paper tape is also more likely to unravel when winding wire harnesses, making it difficult to use for wire harness winding. How to automatically wind release paper tape onto wire harnesses is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] Therefore, this utility model provides a tape unwinding and recycling mechanism and a wire harness tape winding device, which can wrap release paper tape around the wire harness, ensure that the release paper tape does not easily unravel, and realize the recycling of release paper.

[0005] To solve the aforementioned technical problem, this utility model provides a tape unwinding and recycling mechanism, including a first bracket, a first driving component, an unwinding shaft, a winding shaft, and transmission discs. The first driving component is mounted on the first bracket and drives the unwinding shaft to rotate. The unwinding shaft is used to accommodate rolls of release paper tape to support the rolls of release paper tape. The winding shaft is parallel to the unwinding shaft and is rotatably connected to the first bracket for winding and recycling the release paper. Two transmission discs are coaxially fixed to the unwinding shaft to clamp the rolls of release paper tape on the unwinding shaft. The outer peripheral side of the transmission disc abuts against the outer peripheral surface of the winding shaft to frictionally drive the rotation of the winding shaft.

[0006] Preferably, the unwinding shaft has a first shaft end and a second shaft end in the axial direction. The first shaft end is connected to the first bracket, and the second shaft end is suspended. Of the two transmission discs, the transmission disc closer to the second shaft end is detachably connected to the unwinding shaft.

[0007] Preferably, the winding shaft has a third shaft end and a fourth shaft end in the axial direction. The third shaft end is connected to the first bracket, and the fourth shaft end is suspended.

[0013] Preferably, the tape winding mechanism includes a second bracket and a second driving member, the first bracket is connected to the second bracket, and the second driving member drives the second bracket to rotate around the revolution center of the tape unwinding and rewinding mechanism.

[0014] Preferably, the second support is a C-shaped plate that partially surrounds the revolution center of the tape unwinding and rewinding mechanism.

[0015] Preferably, the second drive member drives the second bracket to rotate via a gear assembly.

[0016] Preferably, the wire harness traveling mechanism includes a guide, a wire feed roller, a third drive, and a fourth drive.

The two wire feed rollers are arranged parallel to each other on the wire harness output side of the revolution center of the tape unwinding and rewinding mechanism, and are used to clamp the wire harness and drive it to travel by friction. The third drive drives one of the wire feed rollers to rotate, and the fourth drive drives one of the wire feed rollers to move closer to and away from the other wire feed roller.

[0017] Preferably, the guide is annular and includes a first mating portion and a second mating portion at different positions around the circumference of the wire harness.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Example 1: See Figure 1 and Figure 2 The present invention provides an embodiment of the tape unwinding and recycling mechanism.

[0028] The tape unwinding and rewinding mechanism 1 includes a first bracket 11, a first drive member 12, an unwinding shaft 13, a rewinding shaft 14, and transmission discs 15. The first drive member 12 is mounted on the first bracket 11 and drives the unwinding shaft 13 to rotate. The unwinding shaft 13 is used to provide a roll of release paper tape 2 for carrying the roll of release paper tape 2. The rewinding shaft 14 is parallel to the unwinding shaft 13 and is rotatably connected to the first bracket 11 for winding and rewinding the release paper. The two transmission discs 15 are coaxially fixed to the unwinding shaft 13 to clamp the roll of release paper tape 2 on the unwinding shaft 13. The outer peripheral side of the transmission disc 15 abuts against the outer peripheral surface of the rewinding shaft 14 to frictionally drive the rewinding shaft 14 to rotate.

[0029] In the above description, the first support 11 serves as the foundation of the entire tape unwinding and rewinding mechanism 1 and is used for external connections. The first drive component 12 provides power to the unwinding shaft 13. Since the tape unwinding and rewinding mechanism 1 needs to revolve during use, the weight and volume of the first drive component 12 are minimized; in this embodiment, the first drive component 12 is a micro motor. The unwinding shaft 13 supports the roll of release paper tape 2, which is coaxially mounted on the unwinding shaft 13 and rotates with it. The take-up shaft 14 winds the separated release paper. The take-up shaft 14 does not require a separate power source, thus saving on the number of drive components and reducing the volume and weight of the tape unwinding and rewinding mechanism 1. The take-up shaft 14 rotates under the drive of the transmission disc 15. When the unwind shaft 13 rotates, it drives the transmission disc 15 to rotate. It should be noted that the rotation direction of the roll release paper tape and the rotation direction of the unwind shaft 13 have certain requirements. Assuming that the roll release paper tape is wound clockwise on the unwind shaft, the unwind shaft 13 will rotate clockwise to release the tape.

[0030] Through the above technical solution, on the one hand, the release paper tape on the unwinding shaft 13 can be clamped to prevent the release paper tape from loosening; on the other hand, the friction drive of the winding shaft 14 can be used to drive the winding shaft 14 to wind up the release paper. This utility model can wrap the release paper tape around the wire harness, ensure that the release paper tape is not easily unraveled, and realize the recycling of the release paper.

[0031] In this embodiment, the unwinding shaft 13 has a first shaft end and a second shaft end in the axial direction. The first shaft end is connected to the first bracket 11, and the second shaft end is suspended. Among the two transmission discs 15, the transmission disc 15 closer to the second shaft end is detachably connected to the unwinding shaft 13.

[0032] To facilitate the placement of the roll of release tape 2 onto the unwinding shaft 13 and its clamping by the two drive discs 15, the unwinding shaft 13 is configured as a suspended shaft, and the drive discs 15 are detachable for quick removal, allowing the roll of release tape 2 to be placed onto the unwinding shaft 13. For example, the drive discs 15 are connected to the end face of the unwinding shaft 13 by screws.

[0033] In this embodiment, the winding shaft 14 has a third shaft end and a fourth shaft end in the axial direction. The third shaft end is connected to the first bracket 11, and the fourth shaft end is suspended. The winding shaft 14 is provided with a slot 141 for the release paper to pass through. The slot 141 passes through the outer peripheral surface of the winding shaft 14 and the end face of the fourth shaft end.

[0034] To facilitate the initial fixation of the release liner, the unwinding and rewinding shaft 14 is designed as a suspended shaft with a slot 141. During the rewinding process, the release liner can be easily introduced from the end face of the fourth shaft along the slot 141 and smoothly wound onto the rewinding shaft 14. From a structural design perspective, the through-type design of the slot 141 makes the installation and removal of the release liner extremely simple. Workers only need to align the release liner with the inlet of the slot 141 to quickly complete the insertion, greatly improving the ease of operation and production efficiency of the equipment. Furthermore, the slot 141 effectively constrains the position of the release liner during the rewinding process, preventing deviations, wrinkles, and other defects on the rewinding shaft 14, effectively ensuring the quality of the release liner rewinding and guaranteeing the smooth progress of subsequent processes. Example

[0035] See Figure 3 and Figure 4 The present invention provides an embodiment of a wire harness tape wrapping device.

[0036] The wire harness tape wrapping device includes:

[0037] Rack 3;

[0038] In the tape unwinding and rewinding mechanism 1 of Embodiment 1, the rotation axis of the unwinding shaft 13 extends along the X-axis direction;

[0039] A tape winding mechanism is installed on the frame 3 and is used to drive the tape unwinding and rewinding mechanism 1 to revolve. The axis of revolution of the tape unwinding and rewinding mechanism 1 extends along the X-axis.

[0040] The wire harness traveling mechanism is mounted on the frame 3 and is used to drive the wire harness 4 through the center of rotation of the tape unwinding and rewinding mechanism 1 along the X-axis.

[0041] In the above text, frame 3 serves as the foundation of the wire harness tape winding device, including a frame and some housings. The tape winding mechanism is used to wind the tape released by the tape unwinding and rewinding mechanism around the outside of the wire harness. While the tape is being wound, the wire harness moves along its length, thereby spirally winding the tape around the wire harness. Specifically, in this embodiment, the wire harness tape winding process includes the following steps: First, pull out about 10 cm of tape and wind it around the wire harness 4. Insert the separated release paper into the slot 141 of the take-up shaft 14. While the first drive member 12 drives the unwinding shaft 13 to rotate, the tape winding mechanism drives the tape unwinding and rewinding mechanism 1 to revolve around the wire harness 4. At the same time, the wire harness 4 moves along its length, thus spirally winding the tape around the outside of the wire harness 4. During the tape winding process, the transmission disc 15 clamps the tape to prevent the tape from scattering during rotation, and the take-up shaft 14 also rotates under the drive of the transmission disc 15 to recycle the release paper.

[0042] In this embodiment, the tape winding mechanism includes a second bracket 51 and a second driving member (not shown in the figure). The first bracket 11 is connected to the second bracket 51, and the second driving member drives the second bracket 51 to rotate around the revolution center of the tape unwinding and rewinding mechanism 1.

[0043] The second support 51, as a crucial load-bearing component, forms the basic framework for the entire tape winding mechanism. It is securely connected to the first support 11, for example, through bolting or welding, ensuring a tight bond that prevents loosening or displacement during subsequent complex operations. While not visually represented in the diagram, the second drive component plays a vital role. As the power output, it generates a strong driving force, causing the second support 51 to rotate around the center of the tape unwinding and rewinding mechanism 1. This rotational motion is the key action enabling the entire tape winding process. In practice, the second drive component can use a motor as its power source to rotate the second support 51.

[0044] In this embodiment, the second bracket 51 is a C-shaped plate that partially surrounds the revolution center of the tape unwinding and recycling mechanism 1.

[0045] The C-shaped plate resembles the letter "C" in appearance. The center of the C-shaped plate is the revolution center of the tape unwinding and rewinding mechanism 1. The opening of the C-shaped plate allows the wire harness to quickly and easily enter the inner side of the C-shaped plate and reach the revolution center of the tape unwinding and rewinding mechanism 1.

[0046] In this embodiment, the second driving member drives the second bracket 51 to rotate via a gear assembly (not shown in the figure).

[0047] Gear transmission has the advantages of high efficiency, precise transmission ratio, large load capacity and high transmission reliability. Therefore, by transmitting the second drive component and the second support 51 through the gear assembly, the tape unwinding and rewinding mechanism 1 can be guaranteed to revolve around the wire harness 4 efficiently, reliably and accurately.

[0048] In this embodiment, the wire harness traveling mechanism includes a guide 61, a wire feed roller 62, a third drive member (not shown in the figure), and a fourth drive member (not shown in the figure). The guide 61 is located on the wire harness input side of the revolution center of the tape unwinding and rewinding mechanism 1. The guide 61 is used to allow the wire harness 4 to pass through and guide the wire harness 4 to travel. The two wire feed rollers 62 are arranged parallel to each other on the wire harness output side of the revolution center of the tape unwinding and rewinding mechanism 1. The two wire feed rollers 62 are used to clamp the wire harness 4 and drive the wire harness 4 to travel by friction. The third drive member drives one of the wire feed rollers 62 to rotate, and the fourth drive member drives one of the wire feed rollers 62 to move closer to and away from the other wire feed roller 62.

[0049] The guide 61 is located on the wire harness input side at the center of the tape unwinding and rewinding mechanism 1. This position determines its primary guiding role during the wire harness's movement. It acts like a navigator, indicating the direction for the wire harness 4 to enter subsequent workflows. As the wire harness 4 passes through the guide 61, the guide 61 constrains and guides the wire harness 4 through its structural design. Two feed rollers 62 are arranged parallel to each other on the wire harness output side at the center of the tape unwinding and rewinding mechanism 1. This parallel arrangement allows them to work well together. Their main function is to clamp the wire harness 4, much like two hands holding the wire harness. By adjusting the distance between the two feed rollers 62, different diameter wire harnesses 4 can be accommodated, ensuring sufficient clamping force for effective frictional transmission. When the third drive unit rotates one of the feed rollers 62, the wire harness 4 moves forward along with the rotating feed roller 62 due to the friction between the two feed rollers 62. The third drive unit, as a power source, drives one of the feed rollers 62 to rotate, ensuring the continuous movement of the wire harness 4. It can be a motor, whose rotational motion is transmitted to the feed rollers 62 via a coupling or other transmission method. The function of the fourth drive unit is to move one of the feed rollers 62 closer to and further away from the other. This function is very important, as it can accommodate wire harnesses 4 of different specifications. When handling thicker wire harnesses 4, the fourth drive unit can increase the distance between the two feed rollers 62 to properly clamp the wire harness 4 in the middle; when handling thinner wire harnesses 4, the fourth drive unit can decrease the distance between the two feed rollers 62 to ensure sufficient clamping force on the wire harness 4. The fourth drive unit can be a cylinder or an electric actuator, whose extension and retraction movement adjusts the distance between the feed rollers 62.

[0050] In this embodiment, the guide 61 is annular and includes a first mating portion 611 and a second mating portion 612 surrounding the wire harness 4 at different positions in the circumference. The first mating portion 611 has two first mating ends, and the second mating portion 612 has two second mating ends. One of the first mating ends is hinged to one of the second mating ends, and the other of the first mating ends is detachably quick-connected to the other of the second mating ends.

[0051] The aforementioned guide 61 is similar to a clamp. When the guide 61 is open, it facilitates the entry of the wire harness 4 into the inside of the guide 61. When the guide 61 is closed, it forms a guide hole that guides the wire harness 4 to move forward.

[0052] In this embodiment, a traction trolley (not shown in the figure) is also included. The traction trolley (not shown in the figure) is located on the wire harness output side of the two wire feeding wheels 62. The traction trolley is used to clamp the wire harness 4 and drive the wire harness 4 to move in the output direction.

[0053] To prevent the wire harnesses wrapped with tape from piling up, the aforementioned traction trolley is installed. The traction trolley is equivalent to organizing the wire harnesses, so that the wire harnesses wrapped with tape are piled up in an orderly manner.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
