Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a device for applying adhesive tape to wires and cables. Background Technology

[0002] During the processing of cables and wires, in order to improve their insulation and moisture resistance, they are wrapped with tape to ensure the stability of the line. Similarly, when cables are made into wire harnesses, they also need to be wrapped with tape to ensure the stability of the wire harness and facilitate its laying.

[0003] However, in practical applications, some problems remain unresolved. Here are some common issues with a tape application device for wire and cable processing: When wrapping tape around cables, wires, or wire harnesses, the cable needs to move axially, and then the tape rotates around the outer periphery of the wire harness to wrap the tape. During this process, the wire harness needs to be positioned. When the wire harness is positioned, the diameter of the wire harness increases, which increases the overlap rate of the tape during wrapping, resulting in a smaller coverage area and causing hollow areas after the tape is wrapped, thus affecting the wrapping quality. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a device for applying adhesive tape to wires and cables. The device includes an adhesive base 1, a channel hole 2, an inner ring groove 3, a clearance groove 4, an inner rotating ring 5, a support plate 6, a rotating ring 7, a driving component 8, an inlet clamping component 9, an outlet clamping component 10, and an adhesive tape switching component 11.

[0032] Specifically, the adhesive application base 1 is the base of the entire device, with a through-hole 2 on its side for wires, cables, or wire harnesses to pass through. An inner ring groove 3 is formed within the inner circumference of the through-hole 2, and a clearance groove 4 is formed on the inner wall of the through-hole 2 and communicates with the inner ring groove 3. An inner rotating ring 5 is rotatably connected within the inner ring groove 3. A support plate 6 is fixed to the inner circumference of the inner rotating ring 5, with its end extending into the through-hole 2. The end of the support plate 6 is convex and rotatably connected to a rotating ring 7. The adhesive tape roll is fitted onto the rotating ring 7 and can rotate around it. A driving component 8 is located within the adhesive application base 1 and controls the rotation of the inner rotating ring 5, causing the adhesive tape roll to revolve around the wire harness. An inlet clamp 9 is located on the side of the adhesive application base 1 and guides the wire harness into the through-hole 2 for adhesive tape application, ensuring the wire harness remains taut. The outlet clamp 10 is located on the other side of the adhesive applicator 1, used to guide the wire harness after the tape has been applied to the outside of the channel hole 2, and works with the inlet clamp 9 to maintain the linear movement of the wire harness. The tape switch 11 is located on the inner rotating ring 5, used to automatically replenish new tape when the tape is about to run out.

[0033] Specifically, the wire harness is clamped by the inlet clamp 9 and the outlet clamp 10 and moves axially. The drive unit 8 drives the inner rotating ring 5 to rotate, causing the tape wrapped around the wire harness to revolve. At the same time, the tape roll rotates and unwinds, evenly wrapping the tape around the wire harness. When the tape roll diameter decreases to a set value, the tape switching unit 11 automatically overlaps and pastes the end of the new tape with the end of the old tape to achieve continuous tape supply. At the same time, with the cooperation of the inlet clamp 9 and the outlet clamp 10, the revolve speed of the tape on the inner rotating ring 5 is controlled to avoid the tape overlap rate being too high due to the influence of the wire harness diameter, resulting in the phenomenon of the tape being wrapped inside and hollow.

[0034] The adhesive base 1, channel hole 2, inner rotating ring 5, and rotating ring 7 are existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0035] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the driving component 8 includes a driving groove 12 located at the inner corner of the adhesive base 1. Two conical wheels 13 are connected to the driving groove 12, sliding relative to each other and rotatable, with their conical surfaces facing each other. A driving motor 14 is fixed at the top corner of the side of the adhesive base 1, and the output shaft of the driving motor 14 is inserted into one of the conical wheels 13, driving the conical wheel 13 to rotate. A driving belt 15 is disposed between the two conical wheels 13, with its inner edge inclined and in contact with the conical sides of the two conical wheels 13. The driving belt 15 is also sleeved on the outer periphery of the inner rotating ring 5, which is concave. A flexible ring 16 is fixed to the concave inclined surface to increase the friction with the driving belt 15 and to adapt to the tension of the driving belt 15 driven by the conical wheels 13, allowing the driving belt 15 to fit against the inner rotating ring 5 and the conical wheels 13. When the two conical wheels 13 are close to each other, the diameter of the contact between the drive belt 15 and the conical wheels 13 increases, and the rotation speed of the inner rotating ring 5 increases; conversely, the rotation speed decreases. In addition, when the conical wheels 13 move, they control the arc diameter of the contact between the drive belt 15 and the inner circumference of the flexible ring 16, so that the drive belt 15 is always in a taut state.

[0037] Specifically, the inlet clamping component 9 includes two support blocks 17 disposed on the side of the adhesive base 1 away from the drive motor 14. A support tube 18 is fixed to the support blocks 17, and the end of the support tube 18 extends to the corner of the side of the adhesive base 1, and is connected to the drive groove 12 via a connecting pipe on the outer periphery. The drive tube 19 is fixed to the inner end side wall of the drive groove 12 and inserted into the corresponding conical wheel 13, and is slidably connected to the conical wheel 13. The drive tube 19 is used to draw air towards the conical wheel 13 to adjust the distance between the two conical wheels 13. A pressure stabilizing groove 20 is provided in the bottom corner of the adhesive base 1 opposite to the conical wheel 13. A pressure stabilizing tube 21 is fixed to the inner end side wall of the pressure stabilizing groove 20, and the end of the pressure stabilizing tube 21 is connected to the end of the corresponding support tube 18 to stabilize the air pressure and avoid fluctuations in the clamping force.

[0038] Specifically, clamping rods 22 are slidably connected to the opposite ends of the two support tubes 18, and clamping claws 23 are fixed to the ends of the clamping rods 22 and are arranged crosswise. The end of the clamping rod 22 located inside the support tube 18 extends along the axis of the support tube 18 and passes through the position communicating with the drive groove 12, and is fixed with a piston 25, which is slidably connected to the support tube 18. When the wire harness passes between the two clamping claws 23, the clamping claws 23 are opened, and the clamping rod 22 drives the piston 25 to move, drawing air from the support tube 18 into the support tube 18 through the pipeline, thereby driving the conical wheel 13 to move and adjusting the transmission ratio of the drive belt 15. At the same time, the pressure stabilizing groove 20 absorbs pressure fluctuations, making the clamping force adaptive to the diameter of the wire harness. In addition, the clamping claws 23 are made of ceramic material to reduce the friction between the wire harness and the clamping claws 23.

[0039] Specifically, the outlet clamping component 10 includes two bosses 26 fixed to the adhesive base 1 on one side of the drive motor 14, two support shafts 27 rotatably connected between the two bosses 26, and two concave wheels 28 fixed to the two support shafts 27 respectively. Several arc-shaped blocks 29 are fixed to the peripheral sidewalls of the concave wheels 28. The arc-shaped blocks 29 are made of rubber or silicone and are used to elastically clamp wire harnesses of different diameters. The wire harness passes between the two concave wheels 28, which rotate as the wire harness moves. Simultaneously, the arc-shaped blocks 29 apply a stable clamping force to the wire harness, keeping it taut.

[0040] Specifically, a cavity 30 is formed in the boss 26 near the drive motor 14. The centrifugal column 31 is rotatably connected to the inner wall of the cavity 30, and its end is fixedly connected to the end of the support shaft 27. Several outer pressure plates 32 are inserted into the outer peripheral wall of the centrifugal column 31 and are slidably connected. When the wire harness accelerates, the support shaft 27 drives the centrifugal column 31 to rotate rapidly, and the outer pressure plates 32 slide outward under the action of centrifugal force, squeezing the air in the cavity 30.

[0041] Specifically, a recessed hole 33 is provided on the side wall of the drive groove 12 near the drive motor 14. A limiting ring 34 is inserted into the corresponding conical wheel 13 and fixedly connected to the inner side wall of the drive groove 12 to limit the axial movement range of the conical wheel 13. A connecting channel 35 is provided in the side wall of the adhesive base 1 and communicates with the recessed hole 33 and the cavity 30 respectively. When the outer pressure plate 32 squeezes the air in the cavity 30, the air enters the recessed hole 33 through the connecting channel 35, pushing the corresponding conical wheel 13 closer to the other conical wheel 13, thereby expanding the diameter of the contact between the drive belt 15 and the conical wheel 13, increasing the rotation speed of the inner rotating ring 5, and synchronizing the tape winding speed with the wire harness feeding speed.

[0042] Example 3, referring to Figures 2-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, the tape switching component 11 includes a switching plate 36 fixed to the inner circumferential sidewall of the inner rotating ring 5, a convex shaft 37 fixed to the side of the switching plate 36, and a collar 38 rotatably connected to the outer circumferential side of the convex shaft 37. A polygonal groove 39 is formed inside the switching plate 36, a polygonal rod 40 is slidably connected inside the polygonal groove 39, and a connecting shaft 41 is fixedly connected to its end. The end of the connecting shaft 41 extends to the outside of the convex shaft 37 and is fixedly attached to a pressure plate 42. A clearance hole 43 is formed inside the convex shaft 37 to allow clearance from the connecting shaft 41. A guide shaft 44 is rotatably connected to the side of the pressure plate 42, and a guide rod 45 is rotatably connected to the side of the pressure plate 42, with a gap between it and the guide shaft 44, for guiding the end of the tape to be switched.

[0044] A control cavity plate 46 is fixed to the side of the support plate 6 away from the rotating ring 7. A control plate 47 is inserted into the control cavity plate 46. A connecting rod 48 is fixed to the end side of the control plate 47 and fits against the outer wall of the rotating ring 7. A connecting pipe 49 is fixed to the side of the control cavity plate 46 and communicates with the interior of the control cavity plate 46. The end of the connecting pipe 49 communicates with the polygonal groove 39. In the initial state, the tape roll is sleeved on the rotating ring 7. The control plate 47 is pushed into the control cavity plate 46 by the outer periphery of the tape roll, drawing air out of the connecting pipe 49 and the polygonal groove 39, causing the polygonal rod 40 to be sucked into the polygonal groove 39, and the pressure plate 42 is in a raised state. When the tape roll diameter shrinks to the set number of turns (e.g., 5-10 turns), the control plate 47 gradually resets under the air pressure inside the control cavity plate 46. A spring (not shown in the figure) is fixedly connected between the polygonal rod 40 and the inner wall of the polygonal groove 39 via a bearing. This spring is used to reset the polygonal rod 40 and prevent insufficient air pressure from affecting the polygonal rod 40's entry into the clearance hole 43. Air returns to the polygonal groove 39, pushing the polygonal rod 40 outward. The pressing plate 42 falls, pressing the end of the tape to be switched between the guide shaft 44 and the guide rod 45, and overlapping the end of the tape to be switched with the tail of the old tape that is about to be used (overlap rate of 1 / 2 or 1 / 3), thus realizing automatic continuous tape feeding.

[0045] In use, the wire harness is passed between the two clamping claws 23. Both clamping claws 23 move outward. The support tube 18 located at the voltage stabilizing groove 20 is squeezed by the corresponding clamping rod 22, which forces air into the voltage stabilizing tube 21 and then into the voltage stabilizing groove 20, providing sufficient pressure. The clamping rod 22 located on the drive groove 12 side drives the piston 25 to move, squeezing the air at the inner end of the corresponding support tube 18 and simultaneously adsorbing the air in the drive tube 19, which in turn adsorbs the corresponding conical wheel 13 to move. This reduces the curvature of the drive belt 15 after it comes into contact with the two conical wheels 13, thus reducing the initial rotational speed of the inner rotating ring 5. The tape roll is then fitted onto the rotating ring 7, and a bearing or rotating ring 7 that limits the tape roll is fixed by snapping or magnetic attraction at the outer convex end of the support to prevent the tape from rotating and falling off. Then, the end of the tape is attached to the wire harness.

[0046] The movement of the wire harness is driven by a conveying mechanism, which pulls the wire harness to move. Then, the drive motor 14 drives the conical wheel 13 to rotate. When the conical wheel 13 rotates, it drives the inner rotating ring 5 to rotate through the drive belt 15, which in turn drives the support plate 6 and the rotating ring 7 to move, so that the tape roll revolves around the wire harness. As the tape is wound, the tape roll rotates, so that the tape can be wound onto the wire harness. The tension control uses a tension control system of existing technology to ensure that the tape is in a taut state.

[0047] The wire harness is then passed through the two concave rollers 28 and brought into contact with the arc-shaped blocks 29 on the concave rollers 28. The arc-shaped blocks 29 are made of rubber or silicone to provide flexibility and ensure that they can accommodate the passage of various wire harness diameters. When the wire harness moves, the concave rollers 28, in conjunction with the clamping of the arc-shaped blocks 29 and the clamping of the two clamping claws 23, ensure that the wire harness is kept taut when the tape is wrapped around it, thus preventing the wire harness from bending and affecting the wrapping of the tape.

[0048] When the concave wheel 28 rotates, it drives the support shaft 27 to rotate. The support shaft 27 is connected to the centrifugal column 31 by a gearbox, so that when the support rotates, it can drive the centrifugal column 31 to rotate quickly. When the wire harness is accelerated and fed, it can generate sufficient centrifugal force, which in turn drives the outer pressure plate 32 to move outward, so that the air in the cavity 30 is compressed and enters the concave hole 33 through the connecting channel 35, which in turn compresses the corresponding conical wheel 13, thereby expanding the arc diameter of the drive belt 15 between the two conical wheels 13, adjusting the transmission ratio, increasing the rotation speed of the inner rotating ring 5, and improving the winding efficiency of the tape. It can automatically adjust the winding efficiency of the tape according to the feeding speed of the wire harness.

[0049] Additionally, as the tape is wound, its diameter gradually decreases. Initially, when the tape roll is placed on the rotating ring 7, pulling the connecting rod 48 to fit the outer circumference of the tape roll, and simultaneously pulling the control plate 47, will draw air from the connecting pipe 49 and the polygonal groove 39. At the same time, the switching plate 36 rotates clockwise, causing the polygonal rod 40 to align with the polygonal groove 39, so that the polygonal rod 40 is attracted into the polygonal groove 39, allowing the end of the tape to be wound to wrap between the guide shaft 44 and the guide rod 45. As the initial diameter of the tape decreases (when the initial tape has 5-10 turns remaining), the control... The air inside the cavity plate 46 gradually returns to the polygonal groove 39, thereby pushing the polygonal rod 40 to slide on the connecting shaft 41 (the connecting shaft 41 is slidably connected to the polygonal rod 40 through the cooperation of a key and a keyway), allowing the polygonal rod 40 to return to its original position. Under the influence of gravity of the guide rod 45 and the guide shaft 44, the pressure plate 42 quickly adheres to the initial tape roll, and the end of the tape to be wrapped adheres to the initial tape. The adhesive end of the tape to be wrapped adheres to the initial tape, and the overlap rate is one-half or one-third. Then, tape can be directly replenished, reducing the tape replacement cycle.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
