Description

Technical Field

[0001] This application relates to the field of coil winding technology, and in particular to an electric wire winding fixture. Background Technology

[0002] With the increasing power and frequency of high-power transmitters in China, the size of tuning circuit components has increased significantly. As a crucial component of the tuning circuit, the inductor coil is becoming increasingly critical in the field of communication transmission. The performance of the inductor coil directly affects the working effect of the tuning circuit, and consequently, the overall performance of the high-power transmitter. Continuously improving the manufacturing process and efficiency of inductor coils is of great significance for promoting the development of the communication transmission field.

[0003] In the past, the common method for winding inductor coils was to place multiple spools of wire on a tray equipped with casters. During the winding process, multiple people were needed to work together, with some pushing and rotating the spools to release the wire, while others performed the winding work.

[0004] However, this approach relies on a large amount of human collaboration and requires a high investment of human resources. This not only results in significant financial expenditure but also makes the multi-person collaborative work mode inefficient and unable to meet the ever-increasing production demands. This is especially true given the continuous development of high-power transmitter equipment and the increasing demand for inductors. Summary of the Invention

[0005] In order to reduce labor costs and improve production efficiency, this application provides an electric wire winding tooling device.

[0006] The electric wire winding fixture provided in this application adopts the following technical solution: An electric wire winding fixture includes a frame, a central tray, multiple spool trays, a first drive device, and a second drive device, both of which are mounted on the frame. The central tray is rotatably connected to the frame, and multiple spool trays are rotatably connected to the central tray. Wire rollers are detachably connected to the spool trays. A wire bundle frame is fixedly installed on the frame. The first drive device and the second drive device are used to drive the central tray and the spool trays to rotate synchronously or asynchronously, respectively.

[0007] By adopting the above technical solution, the frame provides support, and devices such as the center tray, spool tray, and wire bundler are all installed on the frame. The wire bundler is used to gather multiple strands of wire together. The center tray and spool tray can rotate synchronously or asynchronously through drive device one and drive device two. This can achieve the following: the center tray can rotate while the spool tray remains stationary, realizing the winding action of multiple strands of wire; the spool tray can rotate while the center tray remains stationary, realizing the wire unwinding action; the center tray and spool tray can rotate simultaneously, realizing the wire winding and wire unwinding actions at the same time. This can save labor costs and improve the working efficiency of winding inductor coil wires.

[0008] Preferably, the cable bundle frame is provided with a cable gathering funnel and a guide bend. The cable gathering funnel is fixedly disposed above the frame and fixedly installed in the middle of the cable bundle frame. The guide bend is connected to the cable gathering funnel. The wire passes through the cable gathering funnel and the guide bend. The opening of the cable gathering funnel is disposed away from the guide bend.

[0009] By adopting the above technical solution, the opening of the wire gathering funnel is set far away from the guide bend, which allows the dispersed multiple wires to naturally converge at the gradually narrowing opening when entering the funnel. This avoids excessive bending of the wires and reduces the friction of the wires. The wires pass through the wire gathering funnel and then through the guide bend, which can change the direction of the wires. This effectively gathers and guides the multiple wires, ensuring that the wires are transmitted in an orderly manner during the winding process.

[0010] Preferably, the drive device includes a first gear ring, a first gear, and a first motor. The first gear ring is fixedly connected to the lower end face of the central tray, the first motor is fixedly mounted on the frame, and the first motor is fixedly connected to the first gear through a reducer. The first gear meshes with the first gear ring.

[0011] By adopting the above technical solution, the first motor starts and drives the first gear to rotate, the first gear rotates and drives the first gear ring to rotate, the first gear ring rotates and drives the central tray to rotate, and the central tray rotates and drives multiple bobbin trays to rotate synchronously, thereby causing multiple strands of wire to intertwine. The reducer installed on the first motor can meet the requirements of low-speed operation and ensure the stable rotation of the central tray.

[0012] Preferably, the spool tray includes a tray frame, a sleeve rod, and a connecting rod. The connecting rod passes through and rotates on the central tray. The tray frame is fixedly connected to the connecting rod. The sleeve rod passes through the tray frame and is fixedly connected to the connecting rod. A drive gear is fixedly sleeved at the bottom end of the connecting rod. A flange is provided between the drive gear and the central tray. The roller includes a base, a winding tube, and a top plate. The base and the top plate are fixedly connected to the bottom and top ends of the winding tube, respectively. The winding tube is sleeved on the sleeve rod. The base abuts against the pallet frame. A stop mechanism for fixing the roller is detachably connected to the sleeve rod. The driving device drives the driving gear to rotate.

[0013] By adopting the above technical solution, the second drive device drives the second gear to rotate, which in turn drives the connecting rod to rotate. The connecting rod then drives the pallet frame to rotate, which in turn drives the wire roller on it to rotate, thus achieving wire feeding. The winding tube of the wire roller is directly sleeved onto the sleeve rod. This design simplifies the installation of the wire roller; the operator only needs to insert the winding tube along the sleeve rod and bring the chassis into contact with the pallet frame to complete the initial positioning. No complicated installation steps or tools are required, greatly improving installation efficiency. The stop mechanism at the top of the sleeve rod effectively fixes the wire roller, preventing it from shifting upwards due to centrifugal force or other external forces during rotation, ensuring the wire roller is always stably mounted on the connecting rod. Simultaneously, the contact between the chassis and the pallet frame provides radial support and fixation for the wire roller, further enhancing the stability of the wire roller installation.

[0014] Preferably, the driving device includes a second gear ring, a second gear, and a second motor. The second gear ring includes an outer gear ring and an inner gear ring. Multiple support brackets are fixedly connected to the frame. The second gear ring rotates on the support brackets. The second motor is mounted on the frame. The second gear is connected to the second motor through a reducer. The second gear meshes with the outer gear ring. All of the multiple driving gears mesh with the inner gear ring.

[0015] By adopting the above technical solution, the second motor drives the second gear to rotate, and the second gear drives the second gear ring to rotate through the outer ring gear ring. The rotation of the second gear ring synchronously drives multiple drive gears to rotate, thereby realizing the winding and unwinding of the wire.

[0016] Preferably, a plurality of through slots are evenly opened on the end face of the second toothed ring, and a roller is rotatably disposed in the through slot, the roller rotating between the central tray and the support frame.

[0017] By adopting the above technical solution, when the second toothed ring rotates, the roller moves along with the rotation of the second toothed ring. The roller rolls and supports the central tray and the support frame, reducing the friction on the end face of the second toothed ring, improving the rotation effect, and preventing the rotation of the second toothed ring from dragging the central tray to rotate.

[0018] Preferably, the stop mechanism includes an abutment plate and multiple limiting plates. The end face of the abutment plate abuts against the top plate. The inner wall of the abutment plate has multiple placement slots, which are evenly distributed along the inner peripheral sidewall of the abutment plate. An arc block is slidably connected in each placement slot. A spring is provided in each placement slot, and both ends of the spring are fixedly connected to the inner wall of the placement slot and the arc block, respectively. The multiple limiting plates are arranged in a one-to-one correspondence with the multiple arc blocks. The limiting plate is fixedly connected to the upper surface of the arc block away from the spring. The limiting plate abuts against the peripheral sidewall of the sleeve rod. The limiting plate is provided with a fixing component for fixing to the sleeve rod. An inclined surface is provided on the side of the arc block opposite to the limiting plate, and the sleeve rod abuts against the inclined surface.

[0019] By adopting the above technical solution, after the online roller is sleeved on the connecting rod, the worker sleeves the abutment plate on the connecting rod. During the sleeve, the top of the connecting rod abuts against the inclined surface on the arc block and pushes the arc block compression spring to move into the placement groove, so that the abutment plate can adapt to a variety of connecting rods with different diameters within a certain range, improving the adaptability of the stop block mechanism. After the sleeve is completed, the worker uses the fixing components to fix the connecting rod with multiple limiting plates clamping.

[0020] Preferably, a plurality of balls are evenly arranged on the end face of the abutment plate near the roller, and the balls rotate on the top plate on the roller.

[0021] By adopting the above technical solution, when the online roller rotates to feed the wire, the top plate rotates relative to the abutment plate. At this time, the ball bearings set between the top plate and the abutment plate can reduce the friction between the two, reduce the friction drive of the top plate on the abutment plate, thereby reducing the upward force of the top plate on the abutment plate and improving the stability of the stop mechanism.

[0022] Preferably, the fixing component includes a nut and a plurality of arc plates, each of which is fixedly connected to the outer side wall of the plurality of limiting plates. The bottom end of the arc plate slides radially on the surface of the abutment plate. The radius of the arc plate increases from the top end to the bottom end. The outer side wall of the arc plate is provided with threads, and the threads on the plurality of arc plates are connected and engaged. The nut is sleeved on the plurality of arc plates and threadedly connected to the arc plates.

[0023] By adopting the above technical solution, after the abutment plate is sleeved on the connecting rod and its bottom abuts against the top plate surface of the roller, the worker sleeves the nut from the top of the limiting plate and threaded it to the outer wall of the arc plate. As the diameter of the arc plate increases downward, the nut gradually tightens the limiting plate and the arc plate against the side wall of the connecting rod when it is screwed in, thereby holding it tightly to the connecting rod, restricting the position of the abutment plate and the limiting plate, and improving the stability of the stop mechanism.

[0024] In summary, this application includes at least one of the following beneficial technical effects: The frame provides support, and devices such as the center tray, spool tray, and wire bundler are all mounted on the frame. The wire bundler is used to gather multiple strands of wire together. The center tray and spool tray can rotate synchronously or asynchronously through drive device one and drive device two. The center tray can rotate while the spool tray remains stationary to achieve the winding action of multiple strands of wire; the spool tray can rotate while the center tray remains stationary to achieve the wire unwinding action; the center tray and spool tray can rotate simultaneously to achieve the winding and unwinding actions of wires at the same time, thereby saving labor costs and improving the working efficiency of winding inductor coil wires. The fact that the opening of the wire gathering funnel is far away from the guide bend allows the dispersed multiple wires to naturally converge at the gradually narrowing opening when they enter the funnel, avoiding excessive bending of the wires and reducing the friction of the wires. The wires pass through the wire gathering funnel and through the guide bend, which can change the direction of the wires and effectively gather and guide the multiple wires, ensuring that the wires are transmitted in an orderly manner during the winding process. When the second toothed ring rotates, the roller moves along with it. The roller rolls and supports the central tray and the support frame, reducing the friction on the end face of the second toothed ring, improving the rotation effect, and preventing the rotation of the second toothed ring from dragging the central tray.

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses an electric wire winding fixture, such as... Figure 1 As shown, the device includes a frame 1, a central tray 2, multiple spool trays 3, a first drive unit 4, and a second drive unit 5. The frame 1 is assembled by welding and riveting together a panel 45 and a support 46. The panel 45 is composed of four steel plates. Two sets of supports 46 are symmetrically welded to the lower end face of the panel 45. The support 46 includes a support frame 47 and a support plate 48. The support plate 48 is arc-shaped and rests against the ground, increasing the support area and improving the support effect. The support frame 47 is triangular, with its top fixedly welded to the lower end face of the panel 45 and its bottom fixedly welded to the support plate 48. The first drive unit 4 and the second drive unit 5 are respectively mounted on the two support plates 48.

[0035] like Figure 1 As shown, the central pallet 2 is supported by four quarter-circular arc-shaped steel plates. The central pallet 2 rotates on the frame 1 and its axis is on the same straight line as the axis of the frame 1. A cross steel frame 49 is provided on the upper end face of the central pallet 2. The cross steel frame 49 is fixed to the upper end face of the central pallet 2 by bolts and is used to assemble and fix the four arc-shaped steel plates. A vertical frame 50 is provided below the central pallet 2. The top of the vertical frame 50 is connected to the central axis position of the lower end face of the central pallet 2 by bearings. The bottom end of the vertical frame 50 is cross-shaped and abuts against the ground to strengthen the support of the central pallet 2 and the frame 1.

[0036] like Figure 1As shown, multiple spool trays 3 are rotatably connected to the end face of the central tray 2 and are evenly distributed along the circumference of the central tray 2. Wire rollers 6 are detachably connected to the spool trays 3. A wire harness frame 7 is fixedly installed on the frame 1. The wire harness frame 7 is equipped with a wire gathering funnel 8 and a guide bend 9. The wire gathering funnel 8 is fixedly positioned directly above the center of the central tray 2 and fixedly installed in the middle of the wire harness frame 7. The guide bend 9 connects to the wire gathering funnel 8. The wire passes through the wire gathering funnel 8 and then through the guide bend 9. The opening of the wire gathering funnel 8 is positioned away from the guide bend 9 so that the dispersed multiple strands can naturally converge at their gradually narrowing opening when entering the funnel, avoiding excessive bending of the wire and reducing the friction of the wire. The wire passes through the wire gathering funnel 8 and then through the guide bend 9. The guide bend 9 can change the direction of the wire, effectively gathering and guiding multiple strands of wire, ensuring orderly transmission of the wire during winding. Drive device 4 and drive device 5 are used to drive the central tray 2 and spool trays 3 to rotate synchronously or asynchronously, respectively.

[0037] like Figure 2 and Figure 3 As shown, each of the four panels 45 has a support frame 27 fixedly welded to its lower end face of the inner ring. The support frame 27 is L-shaped. The drive device 25 includes a second gear ring 22, a second gear 23, and a second motor 24. The second gear ring 22 includes an outer gear ring 25 and an inner gear ring 26. The second gear ring 22 is placed on and rotates on the support frame 27. The central tray 2 is placed on the upper end face of the second gear ring 22. The inner gear ring 26 of the second gear ring 22 is located on the inner diameter side wall of the second gear ring 22, with its teeth facing horizontally. The outer gear ring 25 is located at the outer edge of the lower end face of the second gear ring 22, with its teeth facing vertically downward. The second motor 24 is mounted on the support plate 48. The second motor 24 is equipped with a reducer 28, which can meet the requirements of low-speed operation and ensure stable rotation. The second gear 23 is fixedly connected to the second motor 24 through the reducer 28. The second gear 23 meshes with the outer ring gear 25. When the second motor 24 starts, it can drive the second ring gear 22 to rotate through the second gear 23. At this time, multiple spool trays 3 drive the spool rollers 6 on them to rotate, thereby realizing the unloading of the wire.

[0038] like Figure 3 and Figure 4As shown, ten roller devices 31 are evenly arranged circumferentially on the end face of the second toothed ring 22. Each roller device 31 includes a cover plate 32, rollers 31, and two connecting blocks 33. The two connecting blocks 33 are fixedly welded to both sides of the cover plate 32 and are arranged in parallel. The two end faces of the rollers 31 are rotatably connected to the two connecting blocks 33. Ten through slots 29 are evenly opened circumferentially on the end face of the second toothed ring 22. The ten roller devices 31 are installed in the ten through slots 29. The connecting blocks 33, with the rollers 31, are inserted into the through slots 29. The cover plate 32 abuts against the end face of the second toothed ring 22 and is fixedly connected to the end face of the second toothed ring 22 by screws. The rollers 31 protrude from the two end faces of the second toothed ring 22. The bottom end of the rollers 31 abuts against and rolls on the support frame 27, and the top end abuts against and rolls on the lower end face of the central tray 2. As the roller 31 moves along with the second toothed ring 22, the roller 31 rotates and is supported by the central tray 2 and the support frame 27, reducing the contact area between the second toothed ring 22 and the support frame 27 and the central tray 2, reducing the friction on the end face of the second toothed ring 22, improving the rotation effect, and preventing the rotation of the second toothed ring 22 from dragging the central tray 2 to rotate.

[0039] like Figure 2 and Figure 6 As shown, the bobbin tray 3 includes a tray frame 13, a sleeve rod 14, and a connecting rod 15. The tray frame 13 is disposed on the upper surface of the central tray 2. The connecting rod 15 is disposed vertically and rotates on the central tray 2. The connecting rod 15 is fixedly sleeved on the tray frame 13. The sleeve rod 14 passes through the tray frame 13 along the central axis of the tray and is fixedly connected to the connecting rod 15. A drive gear 17 is fixedly sleeved on the bottom end of the connecting rod 15 located below the central tray 2. A flange 16 is disposed between the drive gear 17 and the central tray 2. The drive gear 17 meshes with the inner ring 26 of the second gear ring 22.

[0040] like Figure 2 and Figure 6As shown, a wire roller 6 is detachably connected to the spool tray 3. The wire roller 6 includes a base 18, a winding tube 19, and a top plate 20. The base 18 and the top plate 20 are fixedly connected to the bottom and top ends of the winding tube 19, respectively. The winding tube 19 is sleeved on the connecting rod 15. The base 18 abuts against the upper surface of the tray frame 13. A stop mechanism 21 for fixing the wire roller 6 is detachably connected to the sleeve rod 14. The second drive device 5 drives the second gear 23 to rotate. The rotation of the second gear 23 synchronously drives multiple drive gears 17 to rotate through the inner ring gear 26. The rotation of the drive gears 17 drives the connecting rod 15 to rotate. The rotation of the connecting rod 15 drives the tray frame 13 to rotate. The rotation of the tray frame 13 drives the wire roller 6 on it to rotate, thereby realizing the wire feeding action. The winding tube 19 of the wire roller 6 is directly sleeved onto the connecting rod 15, simplifying the installation of the wire roller 6. A stop mechanism 21 for fixing the wire roller 6 is provided at the top of the sleeve rod 14, preventing the wire roller 6 from shifting upwards due to centrifugal force or other external forces during rotation, ensuring that the wire roller 6 is always stably mounted on the connecting rod 15. Simultaneously, the contact between the chassis 18 and the pallet frame 13 provides support and radial driving force for the wire roller 6, further enhancing the stability of the wire roller 6 installation.

[0041] like Figure 1 and Figure 2 As shown, the drive device 4 includes a first gear ring 10, a first gear 11, and a first motor 12. The first gear ring 10 is fixedly connected to the lower end face of the central tray 2, and the first motor 12 is fixedly mounted on the support plate 48. The first motor 12 is fixedly connected to the first gear 11 through a reducer 28, and the first gear 11 meshes with the first gear ring 10. When the first motor 12 starts, it drives the first gear 11 to rotate, which in turn drives the first gear ring 10 to rotate. The rotation of the first gear ring 10 drives the central tray 2 to rotate, and the multiple bobbin trays 3 on the central tray 2 follow the central tray 2 in their revolution, causing multiple strands of wire to be wound. At the same time, the drive gear 17 follows the central tray 2 in its revolution. When the second motor 24 is not started and the second gear ring 22 is not rotating, the drive gear 17 rotates on its own axis, thereby causing multiple bobbin rollers 6 to automatically release wire, thus achieving automatic wire release while guiding and winding multiple strands, improving the efficiency of wire winding. When the first motor 12 and the second motor 24 start simultaneously, the center tray 2 rotates, while the bobbin tray 3 does not rotate under the synchronous drive of the drive gear 17 and the second gear ring 22. At this time, the wire winding action is realized.

[0042] like Figure 6 and Figure 7As shown, the stop mechanism 21 includes an abutment plate 34 and multiple limiting plates 35. The lower end face of the abutment plate 34 abuts against the upper surface of the top plate 20 of the roller 6. Multiple placement grooves 36 are evenly distributed circumferentially on the inner wall of the abutment plate 34. The placement grooves 36 extend radially, and an arc block 37 is slidably connected in the placement groove 36. A spring 38 is disposed in the placement groove 36, and the two ends of the spring 38 are respectively fixedly welded to the inner wall of the placement groove 36 and the arc block 37. The multiple limiting plates 35 are arranged one-to-one with the multiple arc blocks 37. The limiting plates 35 are arranged vertically, and their bottom ends are fixedly welded to the upper end face of the arc block 37 away from the spring 38. The cross-section of the limiting blocks is arc-shaped. The bottom end of the arc block 37 is provided with a slope 39. When it is installed, the top end of the connecting rod 15 abuts against the slope 39 on the arc block 37 and pushes the arc block 37 to compress the spring 38 and move it into the placement groove 36. This allows the abutment plate 34 to adapt to a variety of connecting rods 15 with different diameters within a certain range, thus improving the adaptability of the stop block mechanism 21.

[0043] like Figure 6 As shown, a fixing component 41 for fixing to the sleeve rod 14 is provided on the limiting plate 35. The fixing component 41 includes a nut 43 and multiple arc plates 44. The multiple arc plates 44 are respectively fixedly connected to the outer side walls of the multiple limiting plates 35. The limiting plates 35 and the arc plates 44 are both made of metal spring sheet material. The side cross section of the arc block 37 is a right triangle. The lower end face of the arc plate 44 slides radially on the upper surface of the abutment plate 34. The radius of the arc plate 44 increases from the top to the bottom. The outer side wall of the arc plate 44 is provided with threads. The threads on the multiple arc plates 44 are connected and engaged. The nut 43 is sleeved on the multiple arc plates 44 and threadedly connected to the arc plates 44. During the downward screwing of the nut 43, as the radius of the arc plate 44 increases, the nut 43 pulls the multiple arc plates 44 towards the center. The movement of the arc plates 44 drives the limiting plate 35 to move, thereby making the stop mechanism 21 tightly fixed to the sleeve rod 14.

[0044] like Figure 6 As shown, a plurality of balls 40 are evenly arranged on the end face of the abutment plate 34 near the wire roller 6, and the balls 40 rotate on the top plate 20 on the wire roller 6. When the wire roller 6 rotates to feed the wire, the top plate 20 rotates relative to the abutment plate 34. At this time, the balls 40, positioned between the top plate 20 and the abutment plate 34, can reduce the friction between the two, reduce the frictional drive of the top plate 20 on the abutment plate 34, thereby reducing the upward force of the top plate 20 on the abutment plate 34 and improving the stability of the stop mechanism 21.

[0045] The implementation principle of this application embodiment is as follows: the first drive device 4 and the second drive device 5 can respectively drive the first gear ring 10 to rotate the central tray 2 and drive the second gear ring 22 to rotate the drive gear 17. The first motor 12 and the second motor 24 are controlled to start and stop according to production needs, thereby realizing multiple production states. When the central tray 2 rotates and the bobbin tray 3 is stationary, multi-strand wire winding can be realized. When the central tray 2 is stationary and the bobbin tray 3 rotates, wire unwinding can be realized. When both the central tray 2 and the bobbin tray 3 rotate, wire unwinding and winding can be realized simultaneously. This can save labor costs and improve the working efficiency of winding inductor coil wires.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
