Description

A conductive cloth wrapping device for wires Technical Field

[0001] This invention relates to the field of equipment for wrapping conductive cloth around wires, specifically a device for wrapping conductive cloth around wires. Background Technology

[0002] In the antenna manufacturing industry, it is often necessary to wrap a layer of conductive cloth around some wires to meet the requirements of electromagnetic shielding, anti-static properties, and grounding for various electronic devices. One side of the conductive cloth is usually adhesive, and the conductive cloth is wrapped around the wire through this adhesive side.

[0003] Currently, the common method for wrapping conductive cloth is by rubbing. First, the conductive cloth is adhered to the surface of the wire, and then it is wrapped around the wire layer by layer by rubbing. Patent CN113284675B discloses a rubbing wrapping method. First, the conductive cloth is placed in a conductive cloth groove, then the wire to be wrapped is placed in the wire groove of the conductive cloth wrapping device, ensuring that one side of the wire is in contact with the conductive cloth. Finally, the conductive cloth is wrapped around the wire layer by layer by rubbing.

[0004] Currently used wires are mainly divided into two types: cylindrical and flat, consisting of multiple conductors arranged side by side. For cylindrical wires, the existing devices can wrap them by twisting. However, for flat wires, the existing devices cannot use this twisting method to wrap the conductive cloth, which is a problem that urgently needs to be solved in the wrapping of flat wires. Summary of the Invention

[0005] To avoid and overcome the technical problems existing in the prior art, the present invention provides a conductive cloth wrapping device for wires. The present invention can effectively wrap conductive cloth around a flat wire layer by layer.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A conductive cloth wrapping device for wires includes a frame with two sets of tensioning assemblies mounted on the frame, capable of pulling the wire straight from both ends. Wrapping assemblies are arranged on both the upper and lower sides of the wire. Each wrapping assembly includes a pressure plate that approaches and abuts the conductive cloth against one side of the wire. The pressure plate has an air nozzle that bends the horizontal conductive cloth outside the wire to the other side. A roller is arranged beside the pressure plate that approaches the bend in the conductive cloth, rolling the bent conductive cloth against the other side of the wire and bringing the conductive cloth outside the wire back to a horizontal position. The two wrapping assemblies work alternately to wrap the conductive cloth around the wire layer by layer.

[0008] As a further embodiment of the present invention, the wrapping assembly also includes a baffle, which can block the wire side opposite to the roller when the roller rolls the conductive cloth, and the baffle and the pressure plate cooperate to form a right-angle space to clamp the wire.

[0009] As a further embodiment of the present invention: the air nozzles on the pressure plate are arranged at equal intervals along the length of the wire, and each nozzle is connected to the air pump.

[0010] As a further embodiment of the present invention: the pressure plate, the baffle, and the roller are all movably mounted on the frame via corresponding telescopic rods, and the extension and retraction directions of the corresponding telescopic rods coincide with the movement directions of the pressure plate, the baffle, and the roller, respectively.

[0011] As a further embodiment of the present invention, an elastic layer is arranged on the working surfaces of the pressure plate, the baffle, and the roller.

[0012] As a further embodiment of the present invention: the tensioning assembly includes an annular frame mounted on the frame and arranged horizontally, and two positioning grooves arranged opposite to each other are opened on the upper frame surface of the annular frame, and the two ends of the wire are respectively engaged in the positioning grooves; pressure blocks are arranged at the openings of the two positioning grooves, and the pressure blocks can press the wire tightly in the positioning grooves and pull the wire to both ends by friction.

[0013] As a further embodiment of the present invention: a clamping telescopic rod is installed on the frame, and the telescopic direction of the clamping telescopic rod is arranged vertically; a tensioning telescopic rod is fixedly installed on the telescopic end of the clamping telescopic rod, and a pressure block is fixedly installed on the telescopic end of the tensioning telescopic rod, and the telescopic direction of the tensioning telescopic rod is parallel to the length direction of the wire.

[0014] As a further embodiment of the present invention: the roller is rotated and mounted on the rotary seat, the rotary seat is mounted on the telescopic end of the rolling telescopic rod, and the telescopic direction of the rolling telescopic rod is perpendicular to the length direction of the wire.

[0015] As a further embodiment of the present invention: a blocking telescopic rod is fixedly installed on the frame, a baffle is installed on the telescopic end of the blocking telescopic rod, and the telescopic direction of the blocking telescopic rod is arranged vertically.

[0016] As a further embodiment of the present invention: a tensioning telescopic rod is fixedly installed on the frame, a pressure plate is installed on the telescopic end of the tensioning telescopic rod, and the telescopic direction of the tensioning telescopic rod is arranged vertically.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, through the alternating cooperation of two sets of wrapping components and the straightening effect of the tensioning component, can efficiently and evenly wrap the conductive cloth tightly around the flat wire, improving the accuracy and stability of the wrapping and ensuring good contact between the conductive cloth and the wire.

[0019] 2. The addition of the baffle and the pressure plate form a right-angle space, which can not only effectively fix the position of the wire and prevent it from moving during the rolling process, but also ensure that the conductive cloth is flatter and wrinkle-free during rolling, thus improving the wrapping quality and aesthetics.

[0020] 3. The air nozzles are arranged at equal intervals and connected to the air pump, which makes the conductive cloth evenly stressed during the bending process, easy to control the bending angle and position, ensures the continuity and consistency of the conductive cloth wrapping, and improves work efficiency.

[0021] 4. The pressure plate, baffle, and roller are installed movably via telescopic rods, which facilitates flexible adjustment according to wire size and wrapping requirements, improving the adaptability and versatility of the device, and also making maintenance and repair easier.

[0022] 5. The elastic layer on the working surface can reduce damage to the wire and conductive cloth, while increasing friction to ensure that the conductive cloth can adhere tightly to the wire during the rolling process, thus improving the strength and reliability of the wrapping.

[0023] 6. The tensioning assembly adopts a ring frame and positioning groove design, which, combined with the pressing action of the pressure block, can stably pull the straight material and prevent it from shifting or loosening during the wrapping process, thus ensuring the accuracy and stability of the wrapping.

[0024] 7. The combined use of the pressing telescopic rod and the tensioning telescopic rod allows the pressure block to be flexibly adjusted in position and pressure to adapt to the tensioning requirements of different wires, thus improving the flexibility and practicality of the device.

[0025] 8. The roller is mounted on a rotary base and driven by a rolling telescopic rod, allowing the roller to flexibly adjust its position and angle as needed to better adapt to the wrapping requirements of the wire and improve the uniformity and quality of the wrapping.

[0026] 9. The fixed installation and vertical telescopic design of the blocking telescopic rod ensure that the baffle can stably block the opposite side of the roller, ensuring that the conductive cloth will not shift or lift during the rolling process, thus improving the flatness and aesthetics of the wrapping.

[0027] 10. The fixed installation and vertical telescopic design of the tensioning rod ensures that the pressure plate can stably abut against the wire and tightly adhere the conductive cloth to it, guaranteeing the strength of the wrapping and its conductivity. At the same time, the flexibility of the tensioning rod allows for easy adjustment according to the wire size, improving the adaptability and versatility of the device. Attached Figure Description

[0035] 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.

[0036] Please refer to Figures 1 to 6. In this embodiment of the invention, a wire conductive cloth wrapping device includes a frame 1 supported on the ground, and a tensioning component 2 and a cloth wrapping component 3 are installed on the frame 1.

[0037] The tensioning assembly 2 includes a rectangular annular frame 24 mounted on the frame 1, and the annular frame 24 is horizontal. Positioning grooves 241 are provided at the center of two opposing sides of the annular frame 24. The shape of the positioning grooves 241 is adapted to the shape of the wire 4 to facilitate engaging both ends of the wire 4 within the positioning grooves 241. A pressing telescopic rod 21 is arranged above each positioning groove 241, and the extension direction of the pressing telescopic rod 21 is vertical. A tensioning telescopic rod 22 is fixedly installed on the extension end of the pressing telescopic rod 21, and a pressure block 23 is fixedly installed on the extension end of the tensioning telescopic rod 22, with the extension direction of the tensioning telescopic rod 22 parallel to the length direction of the wire 4. In use, the pressing telescopic rod 21 extends, driving the tensioning telescopic rod 22 downward and pressing the pressure block 23 against the wire 4 within the positioning groove 241; finally, the tensioning telescopic rod 22 shortens, and under the action of friction, straightens the wire 4 at both ends.

[0038] Two sets of wrapping components 3 are provided, located on the upper and lower sides of the flat wire 4, respectively. The wrapping component 3 includes a clamping telescopic rod 31 fixedly mounted on the frame 1, with the telescopic direction of the clamping telescopic rod 31 arranged vertically. A pressure plate 311 is fixedly installed on the telescopic end of the clamping telescopic rod 31. The pressure plate 311 has a certain thickness and is cuboid in shape. The length direction of the pressure plate 311 is parallel to the length direction of the wire 4, thus pressing the conductive cloth 5 onto the section of the wire 4 to be wrapped. Air nozzles 3111 are also provided in the non-pressing area of ​​the pressure plate 311. Each air nozzle 3111 is arranged at equal intervals along the length direction of the wire 4 on the pressure plate 311, and each nozzle is connected to an air pump. When the pressure plate 311 presses the conductive cloth 5 onto the wire 4, the portion of the conductive cloth 5 outside the wire 4 remains horizontal due to the inherent flexibility of the conductive cloth 5. At this time, turn on the air pump and blow air from top to bottom onto the conductive cloth 5 outside the wire 4 using the air nozzle 3111, so that it bends downward at about 45 degrees or any angle.

[0039] A rolling telescopic rod 33 is also arranged on the frame 1, with its extension and retraction direction horizontal. A rotary seat 331 is fixedly installed on the extension end of the rolling telescopic rod 33, and various rollers 322 are rotatably installed on the rotary seat 331. The rotation axis of the rollers 322 is parallel to that of the wire 4. When the conductive cloth 5 is bent by air and remains bent under the continuous blowing of the air nozzle 3111, the rolling telescopic rod 33 extends, pushing the rollers 322 closer to the bent conductive cloth 5. The rollers 322 contact the windward side of the conductive cloth 5 and push the conductive cloth 5 to continue bending and adhere to the other side of the wire 4. At the same time, the rollers 322 repeatedly roll the conductive cloth 5 under the reciprocating extension and retraction action of the rolling telescopic rod 33. At this time, the air nozzle 3111 is closed to improve the adhesion of the remaining wires 4. During the entire single bending and rolling process, the conductive cloth 5 located on the outside of the wire 4 is bent 180 degrees, wrapping around the outside of the wire 4, and at the same time, the conductive cloth 5 is brought back to a horizontal state for the next round of bending and rolling. Through multiple rounds of bending and rolling, the entire conductive cloth 5 can be wrapped around the wire 4 one loop at a time.

[0040] During the rolling process of roller 322, to prevent the wire 4 from shifting to one side, a blocking telescopic rod 32 mounted on the frame 1 is arranged on the opposite side of roller 322. The telescopic direction of the blocking telescopic rod 32 is vertically arranged. A baffle 321 is fixedly installed on the telescopic end of the blocking telescopic rod 32 to drive the baffle 321 to extend towards the wire 4 and block the other side of the wire 4 before rolling. At the same time, it cooperates with the pressure plate 311 to form a right-angle space to clamp the wire 4. Meanwhile, the lower end face of the baffle 321 is basically in the same horizontal plane as the lower side face of the wire 4. In this way, roller 322 can roll the conductive cloth 5 onto the lower end face of baffle 321, thereby fixing the wire 4 so that the wire 4 remains stationary during the repeated rolling process of roller 322.

[0041] The specific usage process of this invention is as follows:

[0042] Work Status 1:

[0043] As shown in Figure 3, place both ends of the flat wire 4 into the positioning groove 241, and sequentially activate the clamping telescopic rod 21 and the tensioning telescopic rod 22 to bring the wire 4 into a horizontally taut state. Next, align the edge of the conductive cloth 5 with the wire 4 and press it firmly onto the wire 4. Then, simultaneously activate the abutting telescopic rods on the upper and lower sides of the wire 4. The two abutting telescopic rods extend, and the two pressure plates 311 press the wire 4 and the conductive cloth 5 a second time from the upper and lower sides, further enhancing the initial bonding strength between the conductive cloth 5 and the wire 4. Next, open the upper air nozzle 3111 to blow air onto the conductive cloth 5, bending it at a 45-degree angle or the desired angle.

[0044] Work Status Two:

[0045] As shown in Figure 4, after the conductive cloth 5 is bent at a set angle by the upper air nozzle 3111, the lower abutment telescopic rod retracts, while the upper blocking telescopic rod 32 extends. At this time, the lower pressure plate 311 resets, and the upper baffle 321 extends to the left side of the wire 4 and abuts against the left side of the wire 4. Then, the right-side rolling telescopic rod 33 is activated, causing the roller 322 to abut against the bend of the conductive cloth 5 and continue to bend the conductive cloth 5; at the same time, it adheres to the lower side of the wire 4 and adheres to the bottom surface of the upper baffle 321; then the roller 322 rolls repeatedly several times to improve the tightness of the adhesion.

[0046] Work Status 3:

[0047] As shown in Figure 5, after the right-side roller 322 rolls the wire 4 several times, the right-side roller 322 resets, and the upper baffle 321 resets simultaneously. Then, the lower pressure plate 311 presses against the lower side of the wire 4 again, cooperating with the upper pressure plate 311 to compress the wire 4 and conductive cloth 5, further improving the adhesion. Then, the lower air nozzle 3111 is opened to blow air onto the conductive cloth 5, bending it to a set angle.

[0048] Work Status 4:

[0049] As shown in Figure 6, after the conductive cloth 5 is bent at a set angle by the lower air nozzle 3111, the upper abutment telescopic rod retracts, while the lower blocking telescopic rod 32 extends. At this time, the upper pressure plate 311 resets, and the lower baffle 321 extends to the right side of the wire 4 and abuts against the right side of the wire 4. Then, the left-side rolling telescopic rod 33 is activated, causing the roller 322 to abut against the bend of the conductive cloth 5 and continue to bend the conductive cloth 5; at the same time, it adheres to the upper side of the wire 4 and adheres to the bottom surface of the lower baffle 321; then the roller 322 rolls repeatedly several times to improve the tightness of the adhesion. Afterwards, the roller 322 resets.

[0050] Then, following the working conditions one through four, air is blown and rolled in cycles to wrap the conductive cloth 5 around the wire 4 one loop at a time. When a small portion of the conductive cloth 5 remains outside the wire 4 as shown in Figure 6, it can no longer be rolled by the roller 322. This is because the air force of the nozzle 3111 is increased to bend and press this portion tightly onto the wire 4.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
