Description

Technical Field

[0001] This utility model belongs to the field of copper stranded wire processing technology, specifically relating to a copper stranded wire bundling device. Background Technology

[0002] A copper stranded wire bundling device is used to bundle and arrange copper stranded wires to improve their overall roundness and quality. It is commonly found in the wire and cable manufacturing industry. In the fields of wire and cable, and power transmission, copper stranded wire is widely used due to its excellent conductivity and mechanical strength. Its structural roundness directly affects conductivity, weather resistance, and subsequent processing quality. To ensure the roundness of the copper stranded wire, the bundling device, as a key piece of equipment, needs to perform rounding processing on the wire blank formed by stranding multiple copper wires, making the wire cross-section approach a standard circle.

[0003] A search revealed that CN118737577A discloses a copper stranded wire harness device, which includes a height adjustment frame. A placement ring and an annular slide rail are connected to the height adjustment frame. The axes of the placement ring and the annular slide rail are on the same horizontal line. A wire wheel is placed inside the placement ring. The placement ring is provided with a clamp for clamping and fixing the wire wheel. A rolling mechanism is provided on the annular slide rail.

[0004] Existing wire bundling devices struggle to achieve coordinated real-time shape detection and targeted rounding of copper stranded wires. In actual production, localized shape anomalies frequently occur, such as asymmetrical deformations like vertical bulges or lateral depressions. Due to the lack of a dynamic detection mechanism for the cross-sectional shape of the copper stranded wire, rounding can only be performed uniformly according to preset parameters. When specific deformations such as vertical bulges exist in the copper stranded wire, applying pressure in a fixed pattern can lead to insufficient pressure on the bulging areas, making correction difficult. In some cases, excessive pressure on normal areas may even damage the wire, affecting not only the rounding effect but also reducing production efficiency and product yield. Utility Model Content

[0005] The purpose of this utility model is to provide a copper stranded wire bundling device to solve the problem mentioned in the background art that the existing bundling devices are difficult to achieve the coordinated operation of real-time shape detection and targeted rounding of copper stranded wires. In actual production, local shape abnormalities often occur. Due to the lack of a dynamic detection mechanism for the cross-sectional shape of copper stranded wires, they can only be uniformly rounded according to preset parameters.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A copper stranded wire bundling device includes: a wire guide base, which has a channel formed inside for the copper stranded wire to pass through axially;

[0008] Several wire harness holders are arranged in an array along the circumferential direction of the wire guide and are movably installed in the channel of the wire guide. The inner end of the wire harness holder is used to directly apply pressure to the surface of the copper stranded wire.

[0009] Several detection plates correspond one-to-one with the cable bundle holders and are connected by a linkage mechanism. The detection plates are used to fit the surface of the copper stranded wire to detect its local shape, and the linkage mechanism drives the corresponding cable bundle holders to adjust the pressure amplitude.

[0010] Preferably, the wire guide includes:

[0011] An adjustment groove is formed on the inner wall of the cable guide, and the cable harness is connected to the adjustment groove;

[0012] The control slot is located on the inner wall of the wire guide, and the detection board is installed inside the control slot.

[0013] Preferably, the wire guide further includes:

[0014] The moving groove is located on the side wall of the adjusting groove;

[0015] The movable block is installed on one side of the cable tie base and is connected to the movable slot.

[0016] Preferably, the linkage mechanism includes:

[0017] A connecting rod is installed in the control slot, with one end of the connecting rod extending into the moving slot;

[0018] The first bevel gear is installed at one end of the connecting rod;

[0019] The second bevel gear is mounted on the control panel and meshes with the first bevel gear.

[0020] The worm gear is installed at the other end of the connecting rod;

[0021] The lead screw is installed in the moving slot and is threadedly connected to the moving block.

[0022] The worm gear is mounted on the lead screw, and the worm meshes with the worm wheel.

[0023] Preferably, the detection plate includes:

[0024] The detection wheel is installed at one end of the detection plate and contacts the surface of the copper stranded wire.

[0025] Preferably, an elastic element is installed between the detection plate and the inner wall of the control groove.

[0030] Preferably, a through hole is provided on the inner wall of the control groove, the control groove is connected to the moving groove through the through hole, and the connecting rod is disposed in the through hole.

[0031] Preferably, the inner wall of the control groove is connected to a rotating shaft, and the detection plate is connected to the inner wall of the control groove through the rotating shaft.

[0032] This invention provides a copper stranded wire bundling device. Compared with the prior art, it has the following advantages: By dynamically attaching the detection plate to the surface of the copper stranded wire, local shape anomalies can be captured in real time. The detection signal is directly converted into pressure adjustment action of the bundling seat through a linkage mechanism, forming a closed-loop coordination to ensure that the rounding operation always matches the actual shape of the copper stranded wire. It accurately corrects local asymmetric deformations. For specific deformations such as upper and lower protrusions, the detection plate at the corresponding position can drive the bundling seat to increase the pressure amplitude through the linkage mechanism, while the bundling seat in the normal shape area maintains moderate pressure, preventing excessive compression of normal parts and improving the correction accuracy of asymmetric deformations.

Detailed Implementation

[0039] 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.

[0040] Reference Figures 1-5 A copper stranded wire bundling device includes: a wire guide 100, with an internal channel for the axial passage of copper stranded wires; a plurality of bundling seats 200, arranged in an array along the circumferential direction of the wire guide 100 and movably installed within the channel of the wire guide 100, the inner end of the bundling seat 200 being used to directly apply pressure to the surface of the copper stranded wire; and a plurality of detection plates 300, corresponding one-to-one with the bundling seats 200 and connected by a linkage mechanism, the detection plates 300 being used to conform to the surface of the copper stranded wire to detect its local shape, and driving the corresponding bundling seat 200 to adjust the pressure amplitude through the linkage mechanism.

[0041] The axial channel of the copper stranded wire is constructed by the wire guide 100, and the movable wire bundle holders 200 distributed in a circumferential array serve as the pressure application actuators. They are paired with detection plates 300 that correspond one-to-one with the wire bundle holders 200. A direct correlation between detection and pressure application is established through a linkage mechanism, forming a closed-loop structure from detection to feedback and then to adjustment. The detection plate 300 directly adheres to the surface of the copper stranded wire to obtain local shape information. The wire bundle holder 200 adjusts the pressure applied to the corresponding position of the copper stranded wire in real time through the linkage mechanism based on the detection results, realizing the coordinated linkage between detection and rounding action.

[0042] It can specifically solve the problem of rounding copper stranded wires with abnormal local shape. When a bulge is detected in a certain direction (such as the up and down direction) of the copper stranded wire, the detection plate 300 at the corresponding position can drive the wire bundle holder 200 in that direction to increase the pressure through the linkage mechanism, while the wire bundle holder 200 in the area with normal shape maintains moderate pressure. This improves the accuracy and consistency of rounding copper stranded wires, while reducing the risk of wire damage caused by improper pressure. It is beneficial to improve product qualification rate and production efficiency.

[0043] The cable guide 100 includes: an adjustment groove 101, formed on the inner wall of the cable guide 100, with the cable bundle 200 connected to the adjustment groove 101; a control groove 103, formed on the inner wall of the cable guide 100, with the detection plate 300 installed in the control groove 103; a moving groove 102, formed on the side wall of the adjustment groove 101; and a moving block 202, installed on one side of the cable bundle 200, with the moving block 202 connected to the moving groove 102.

[0044] The adjustment groove 101 of the wire guide 100 extends radially, providing radial movement space for the wire bundle holder 200, allowing the wire bundle holder 200 to move closer to or further away from the copper stranded wire along the radial direction of the wire guide 100, ensuring that its inner end can adjust the distance with the copper stranded wire as needed; the control groove 103 is also opened radially, and corresponds one-to-one with the adjustment groove 101 in the circumferential direction, providing a radial movement path for the detection plate 300, allowing the detection plate 300 to move radially synchronously with the change of the surface shape of the copper stranded wire, ensuring the real-time performance of the detection. The movable groove 102 is radially opened along the adjusting groove 101. The movable block 202 is slidably engaged with the movable groove 102, which guides and limits the movement of the cable tie 200, preventing the cable tie 200 from shifting circumferentially or shaking during the pressure application process, and ensuring that it always moves accurately in the radial direction. At the same time, the movable block 202 is rigidly connected to the cable tie 200, which can stably transmit the driving force transmitted by the linkage mechanism to the cable tie 200, making the pressure adjustment of the cable tie 200 more stable and reliable.

[0045] The linkage mechanism includes: a connecting rod 400, installed in the control slot 103, with one end of the connecting rod 400 extending into the moving slot 102; a first bevel gear 401, installed at one end of the connecting rod 400; a second bevel gear 402, installed on the control plate, meshing with the first bevel gear 401; a worm gear 403, installed at the other end of the connecting rod 400; a lead screw 405, installed in the moving slot 102, threadedly connected to the moving block 202; and a worm wheel 404, installed on the lead screw 405, meshing with the worm gear 403.

[0046] The linkage mechanism achieves mechanical linkage between the detection plate 300 and the wire harness seat 200 through the transmission of the first bevel gear 401, the second bevel gear 402, and the lead screw 405: When the detection plate 300 senses a local shape change (such as a protrusion pushing the detection plate 300 to move radially outward along the control groove 103) while in contact with the surface of the copper stranded wire, it will drive the detection plate 300 to rotate. The detection plate 300 drives the second bevel gear 402 to rotate synchronously. Since the second bevel gear 402 meshes with the first bevel gear 401 at one end of the connecting rod 400, the displacement of the detection plate 300 can be converted into a connection. The rotational movement of rod 400; the worm gear 403 at the other end of connecting rod 400 rotates synchronously with connecting rod 400, and through meshing transmission with worm wheel 404 on lead screw 405, it drives lead screw 405 to rotate in moving groove 102; since lead screw 405 is threadedly connected to moving block 202, and moving block 202 is limited by moving groove 102 and cannot rotate, the rotational movement of lead screw 405 is converted into the radial movement of moving block 202 along moving groove 102, which ultimately drives the wire harness seat 200 to approach or move away from the copper stranded wire, so as to achieve precise adjustment of the pressure amplitude at the corresponding position.

[0047] The detection plate 300 includes: a detection wheel 301, which is installed at one end of the detection plate 300 and contacts the surface of the copper stranded wire; an elastic element 302 is installed between the detection plate 300 and the inner wall of the control groove 103.

[0048] The elastic element 302 can be a spring or a sheet. The detection plate 300 achieves dynamic sensing of the surface shape of the copper stranded wire through the cooperation of the detection wheel 301 and the elastic element 302. The outer circumferential surface of the detection wheel 301 directly rolls in contact with the surface of the copper stranded wire, which can reduce frictional damage to the surface of the copper stranded wire and accurately capture the shape features such as bulges and depressions of the wire through changes in the rolling posture. The elastic element 302 is arranged radially along the control groove 103. One end of it is connected to the side of the detection plate 300 away from the detection wheel 301, and the other end is fixed to the inner wall of the control groove 103. It applies force to the detection plate 300 in a direction that... The preload of the copper stranded wire ensures that the detection wheel 301 is always in close contact with the surface of the copper stranded wire. Even if the copper stranded wire shakes slightly or its shape fluctuates, it can maintain stable contact to obtain accurate shape signals. When a protrusion appears in a certain part of the copper stranded wire, it will push the detection wheel 301 at the corresponding position to drive the detection plate 300 to rotate along the control groove 103 and compress the elastic element 302, triggering the linkage mechanism to start the pressure adjustment of the wire harness seat 200. When the shape of that part returns to normal, the rebound force of the elastic element 302 will push the detection plate 300 to reset, so that the detection wheel 301 re-attaches to the surface of the wire, realizing continuous dynamic detection of the shape of the copper stranded wire.

[0049] The wire harness 200 includes a wire harness roller 201, which is installed at one end of the wire harness 200 and contacts the surface of the copper stranded wire. The wire harness 200 applies rolling pressure to the copper stranded wire through the wire harness roller 201. The wire harness roller 201 has a rotatable structure, and its outer circumferential surface is in direct contact with the surface of the copper stranded wire. When pressure is applied to the copper stranded wire, it rolls in coordination with the axial movement of the wire body. This reduces frictional damage to the surface of the copper stranded wire and makes the pressure distribution more even through the uniform contact of the roller surface, thus avoiding wire deformation caused by excessive local compression.

[0050] The cable guide 100 includes a guide sleeve 104, which is installed at one end of the cable guide 100. The guide sleeve 104 of the cable guide 100 has a trumpet-shaped or smoothly transitioned cylindrical structure and is installed at the end of the cable guide 100 where the copper stranded wire enters. Its inner diameter gradually narrows along the direction of the copper stranded wire to match the inner diameter of the channel of the cable guide 100, which can guide and straighten the copper stranded wire entering the channel.

[0051] The inner wall of the control groove 103 is provided with a through hole, and the control groove 103 is connected to the moving groove 102 through the through hole. The connecting rod 400 is disposed in the through hole.

[0052] The inner wall of the control groove 103 is connected to a rotating shaft, and the detection plate 300 is connected to the inner wall of the control groove 103 through the rotating shaft. The rotating shaft of the inner wall of the control groove 103 is horizontally arranged along the circumference of the wire seat 100. The detection plate 300 is rotatably connected to the inner wall of the control groove 103 through the rotating shaft, so that the detection plate 300 can swing around the rotating shaft. With the pre-tightening force of the elastic element 302, when the detection wheel 301 contacts the protruding part of the copper stranded wire, the detection plate 300 can swing outward with the rotating shaft as the fulcrum, converting the radial shape change of the wire into its own angular displacement, and then driving the connecting rod 400 to rotate through the second bevel gear 402.

[0053] During use, the copper stranded wire first enters the channel of the wire holder 100 through the guide sleeve 104. The guide sleeve 104 guides and straightens the copper stranded wire through its gradually changing inner diameter structure, ensuring its stable axial entry into the channel. After entering the channel, the surface of the copper stranded wire contacts the detection wheels 301 of each detection plate 300. Under the pre-tightening force of the elastic element 302, the detection wheels 301 tightly adhere to the surface of the copper stranded wire and roll as the copper stranded wire moves axially, sensing the local shape of the wire surface in real time. When a protrusion exists in a certain part of the copper stranded wire... This will push the corresponding detection wheel 301, causing the detection plate 300 to swing around the pivot of the inner wall of the control groove 103, while simultaneously compressing the elastic element 302. The swinging of the detection plate 300 drives the second bevel gear 402 on it to rotate synchronously. Because the second bevel gear 402 meshes with the first bevel gear 401 at one end of the connecting rod 400, the angular displacement of the detection plate 300 is converted into the rotational motion of the connecting rod 400. The rotation of the connecting rod 400 drives the worm gear 403 at the other end to rotate, and the worm gear 403 and the worm wheel 4 on the lead screw 405 rotate. 04 Engagement, drive the lead screw 405 to rotate in the moving groove 102. Since the lead screw 405 is threadedly connected to the moving block 202 and the moving block 202 is limited by the moving groove 102, the rotation of the lead screw 405 is converted into the radial movement of the moving block 202 along the moving groove 102, which drives the wire harness 200 to move closer to the copper stranded wire along the adjusting groove 101, so that the wire harness roller 201 at the end of the wire harness 200 contacts the protruding part of the copper stranded wire and applies greater pressure. The protruding part is rounded in a targeted manner through the rolling engagement of the wire harness roller 201. After the copper stranded wire is rounded, the protruding part returns to its normal shape. The rebound force of the elastic element 302 pushes the detection plate 300 to reset, and the detection wheel 301 re-fits the surface of the wire. The linkage mechanism reverses the transmission, causing the lead screw 405 to reverse, which drives the moving block 202 and the wire bundle seat 200 to retract, and the pressure of the wire bundle roller 201 decreases. As the copper stranded wire continues to move axially, the above detection, transmission, pressure, and reset processes are repeated, realizing dynamic detection and targeted rounding of the copper stranded wire in the entire circumference, and finally completing the wire bundle operation of the copper stranded wire.
