Description

Technical Field

[0001] This invention relates to the field of automated processing technology for wireless charging coils, and more particularly to a winding device and method for a wireless charging coil. Background Technology

[0002] Wireless charging coils are the core electromagnetic induction components of wireless charging devices. Their structural regularity, wire arrangement tightness, and overall molding stability directly determine the electromagnetic coupling efficiency, charging stability, and product lifespan of the wireless charging device. With the rapid development of new energy, smart wearables, and smart homes, the market demand for wireless charging coils continues to rise, while simultaneously placing higher demands on coil integration, structural strength, electromagnetic performance, and mass production consistency. Wireless charging coils formed by winding multiple insulated wires together, with their advantages of large conductive cross-sectional area, low internal resistance, low heat generation, and excellent electromagnetic conduction performance, are gradually becoming the mainstream configuration for high-end wireless charging devices.

[0003] Currently, existing wireless charging coil winding equipment still suffers from numerous technical defects in the process of winding multiple wires. First, traditional winding equipment mostly adopts a single winding mode, lacking a precise synchronous twisting structure. When winding multiple insulated wires, problems such as scattered arrangement, uneven spacing, and inconsistent twisting angles easily occur, resulting in poor wire bonding and a loose structure in the formed coil. This not only significantly reduces the overall structural strength of the coil but also causes uneven electromagnetic coupling, affecting the transmission efficiency and stability of wireless charging.

[0004] Secondly, existing equipment often involves independent, step-by-step processes such as twisting, winding, cutting, and wire fixing, resulting in low levels of automation. This necessitates significant manual assistance for positioning, arranging, and fixing the wires, leading to cumbersome processes, low efficiency, and high batch-to-batch variations and defect rates. This fails to meet the demands of large-scale, automated mass production. Furthermore, traditional processes lack a reliable overall curing structure after multiple wires are wound; the wires are only held together by winding tension, making them prone to loose strands, misalignment, and deformation during use. Consequently, coil durability and product yield are difficult to guarantee.

[0005] Furthermore, existing winding equipment lacks sufficient precision in positioning, merging, and limiting the wires. Multiple wires are prone to misalignment, crossing, and overlapping during transport and winding, failing to maintain a consistently neat and tightly aligned state. This results in poor overall coil integrity, severely restricting the product quality and performance of wireless charging coils. In addition, traditional equipment has poor structural adaptability, unable to flexibly adjust wire positions and processing stations according to production needs, resulting in insufficient processing flexibility and versatility.

[0006] In summary, existing wireless charging coil winding technologies suffer from problems such as poor twisting uniformity, irregular conductor arrangement, low coil forming stability, insufficient automation, low production efficiency, and poor product consistency, making it difficult to meet the mass production requirements of high-quality, large-scale wireless charging coils. Therefore, how to provide a wireless charging coil winding device and method that can overcome the above problems is a problem that urgently needs to be solved by those skilled in the art.

[0016] A method for winding a wireless charging coil, using the aforementioned winding device for a wireless charging coil, the method comprising: The first step involves placing multiple wires between the moving mold and the stationary mold after they pass through the twisted wire component simultaneously. The second step involves the clamping components simultaneously clamping multiple wires located between the moving mold and the fixed mold. The third step involves the telescopic component moving the moving mold a set distance so that multiple wires simultaneously contact the moving mold and the fixed mold. Fourth step, the rotary drive mechanism two drives the moving mold and the fixed mold to rotate synchronously, and multiple wires are wound around the central shaft at the same time. For every 360° rotation of the moving mold, the rotary drive mechanism one drives the twisted wire component to rotate 180°. After every 180° rotation, the twisted wire component rotates in the opposite direction, and the cycle alternates. Fifth step: After the multiple wires are wound around the central shaft a rated number of times, the moving mold, the fixed mold, and the twisting component stop rotating, and the wire cutter cuts the multiple wires located between the fixed mold and the twisting component; The sixth step involves electrically connecting the two ends of multiple wires wound around the central shaft to the positive and negative electrodes for a set duration. The multiple wires wound around the central shaft are energized and short-circuited to generate heat, causing the insulation layer on the surface of the wires to melt. The multiple wires wound around the central shaft are then fixed together by the cooled insulation layer after melting. Step 7: Once the telescopic component moves the moving mold back to its original position, the coil formed by winding multiple wires will be transferred.

[0017] The advantages and effects of the winding device and method for a wireless charging coil described in this invention are as follows: 1. This application can wind and alternately twist multiple wires, resulting in high twisting uniformity. Twisting strengthens the overall integrity of the final coil, ensuring good adhesion between wires and preventing loosening. The multiple wires are arranged neatly and tightly during the winding process, significantly improving the overall structural strength and electromagnetic coupling conduction performance of the coil. After the multiple wires are wound, they are heated by short-circuiting with electricity, causing the insulation layer to slightly melt and then solidify, thus ensuring that the multiple wires are fixed into a whole. The winding, alternating twisting, cutting, and melting of the wires are completed in one step, simplifying the production process and reducing manual intervention, improving production efficiency and quality stability, reducing defective products, and realizing continuous and automated mass production of wireless charging coils. The equipment is highly adaptable and practical for production.

[0018] 2. The twisting component in this application is provided with a wire-passing channel, and multiple wires are arranged sequentially along the cross-sectional length of the wire-passing channel. When the rotation drive mechanism drives the twisting component to rotate, the multiple wires arranged in parallel can twist synchronously, that is, when twisting, the multiple wires can still maintain a state of sequential parallel and close contact.

[0019] 3. Motor 1 drives the twisting component to rotate reliably via synchronous pulley 1, synchronous pulley 2 and synchronous belt; linear module 1, linear module 2 and linear module 3 can drive the twisting component on the support frame to flexibly change position relative to the frame, thereby ensuring that multiple wires removed from the wire threading channel can be accurately arranged between the fixed mold and the moving mold, and that multiple taut wires removed from the wire threading channel can be arranged radially along the fixed mold.

[0020] 4. The telescopic component can drive the moving mold to move vertically, and the rotary drive mechanism can drive the moving mold and the fixed mold to rotate synchronously. After the wires are arranged between the fixed mold and the moving mold, the moving mold moves down and rotates synchronously with the fixed mold. Multiple wires can be wound synchronously on the central axis. The moving mold and the fixed mold can limit the multiple wires to ensure that the multiple wires remain parallel and close together during the winding process.

[0021] 5. This application relies on the elastic force of the spring to keep the clamping block pressed against the mounting block at all times, and the telescopic part can push against the abutment, thereby realizing the separation of the clamping block and the mounting block, which facilitates the subsequent arrangement of multiple wires between the clamping block and the mounting block. The clamping block and the mounting block can reliably clamp multiple wires; at the same time, the mounting block can be electrically connected to the negative electrode, and the multiple wires located between the mounting block and the clamping block can be reliably electrically connected to the negative electrode.

[0022] 6. The clamping cylinder can drive the clamping block one, clamping block two and the wire cutter to clamp and cut multiple wires between the twisting part and the fixed mold. The clamping block one is electrically connected to the positive electrode, so that one end of the coil after winding is electrically connected to the positive electrode.

[0023] 7. Clamping block one has a protrusion and clamping block two has a groove. This design ensures that clamping block one and clamping block two can clamp multiple wires. On the other hand, the design of the protrusion and groove can further damage the insulation layer of the wires, ensuring that clamping block one can make full contact with multiple wires and conduct electricity at the same time.

[0024] 8. Linear module four, linear module five, and linear module six can drive clamping block one, clamping block two, and the wire cutter to move, ensuring that the multiple wires between the fixed mold and the twisting component can be accurately arranged between clamping block one and clamping block two.

[0025] 9. The telescopic component can drive the conductive component to move, and the conductive component can abut against the mounting block and conduct electricity. This design ensures that one end of the multiple wires wound around the central shaft can be electrically connected to the conductive component, and also ensures that the fixed mold can rotate smoothly.

[0026] 10. By designing the lead wire assembly, the wire clamping component can hold and move multiple wires that have moved out of the wire threading channel, thereby enabling the multiple wires to be accurately arranged between the fixed mold and the moving mold.

[0027] 11. By designing an auxiliary paralleling component, the paralleling notch can press multiple wires together, ensuring that the multiple wires arranged between the moving mold and the fixed mold are parallel and close together, thereby improving the winding effect.

[0028] 12. Linear module eight, linear module nine, and linear module ten can drive the parallel block to move flexibly, ensuring that multiple conductors can be arranged within the parallel opening.

[0029] 13. Linear module eleven and linear module twelfth can drive the heating rod to move flexibly. The heating rod can heat through the insulation layer of multiple wires to ensure that the wound coil is energized.

[0030] 14. By designing the whole-line assembly, multiple wires can be precisely arranged side by side in the wiring channel.

[0031] 15. By designing a transfer component, the coils wound between the fixed mold and the moving mold can be transferred quickly and accurately through the transfer component.

[0032] 16. The winding method of this wireless charging coil is simple and effective. Combined with this winding device, multiple wires can be wound quickly and accurately, and the resulting coil has stable quality. Attached Figure Description

[0037] See appendix Figure 1-13 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. Specifically, the present invention discloses a winding device for a wireless charging coil, the device comprising: The frame 01 is stably arranged on the ground and has length, width and height directions.

[0038] The wire twisting assembly includes a rotary drive mechanism 02 and a wire twisting component 03. The rotary drive mechanism 02 is mounted on a frame 01, and the wire twisting component 03 is fixed to the rotation output end of the rotary drive mechanism 02. The rotary drive mechanism 02 can drive the wire twisting component 03 to rotate. The wire twisting component 03 is provided with a wire threading channel 030. The rotation axis of the wire twisting component 03 relative to the rotary drive mechanism 02 coincides with the center line of the wire threading channel 030 along its length. Multiple wires with insulating layers on their surfaces are simultaneously threaded through the wire threading channel 030. The multiple wires are arranged sequentially along the cross-sectional length of the wire threading channel 030. In this embodiment, the cross-section of the wires is rectangular, and the cross-sectional shape of the wire threading channel 030 is strip-shaped. Multiple wires are arranged sequentially and closely along the cross-sectional length of the wire threading channel 030, and all multiple wires are in contact with the inner wall of the wire threading channel 030. When the wire twisting component 03 rotates, the multiple parallel wires in the wire threading channel 030 can be twisted as a whole.

[0039] The winding assembly includes a telescopic component 09, a moving mold 10, a fixed mold 11, a rotary drive mechanism 12, a clamping component, and a central shaft 19. The telescopic component 09 is fixedly mounted on the frame 01. In this embodiment, the telescopic end of the telescopic component 09 is arranged vertically. The telescopic component 09 in this embodiment is an electric linear module. The moving mold 10 is rotatably connected to the telescopic end of the telescopic component 09. The rotation axis of the moving mold 10 relative to the telescopic end of the telescopic component 09 coincides with the axis of the moving mold 10. The axis of the moving mold 10 is parallel to the telescopic direction of the telescopic end of the telescopic component 09, that is, the axis of the moving mold 10 is arranged vertically. The fixed mold 11 is rotatably mounted on the frame 01. The rotation axis of the fixed mold 11 relative to the frame 01 coincides with the axis of rotation of the fixed mold 11. The fixed mold 11 and the moving mold 10 are arranged coaxially. The axis of rotation of the fixed mold 11 is perpendicular to the rotation axis of the twisting member 03. The twisting member 03 and the fixed mold 11 are arranged sequentially along the length of the frame 01. The rotary drive mechanism 2 12 is connected to both the moving mold 10 and the fixed mold 11. Specifically, the rotary drive mechanism 2 12 includes a motor 2 120 and a drive shaft 121. The motor 2 120 is fixed on the frame 01, and the drive shaft 121 is rotatably mounted on the frame 01. The drive shaft 121 is arranged vertically, and the output shaft of the motor 2 120 is coaxially fixed with the drive shaft 121. The moving mold 10 and the drive shaft 121, as well as the fixed mold 11 and the drive shaft 121, are driven by belt transmission. The motor 2 120 can drive the moving mold 10 and the fixed mold 11 to rotate at the same speed and in the same direction. The clamping element is mounted on the fixed mold 11, and multiple wires from the wire-threading channel 030 are clamped and fixed by the clamping element. The central shaft 19 is coaxially mounted on the fixed mold 11, and when the moving mold 10 moves downward, the upper end of the central shaft 19 can abut against the lower end face of the moving mold 10. When the moving mold 10 and the fixed mold 11 rotate, the multiple wires clamped by the clamping element are wound around the central shaft 19.

[0040] The upper end face of the fixed mold 11 is provided with a relief groove 1, which is arranged radially along the fixed mold 11. The lower end face of the moving mold 10 is provided with a relief groove 2, which is arranged radially along the moving mold 10. The relief groove 1 and the relief groove 2 are directly opposite each other in the vertical position. The purpose of the design of the relief groove 1 and the relief groove 2 is that when winding multiple wires, since the moving mold 10 rotates 360°, the twisting part 03 rotates 180°. The twisting area of ​​the multiple wires located between the fixed mold 11 and the moving mold 10 is located in the area jointly defined by the relief groove 1 and the relief groove 2.

[0041] The wire cutting assembly is mounted on the frame 01. The wire cutting assembly includes a wire cutting blade 20. After multiple wires are wound between the moving mold 10 and the fixed mold 11, the wire cutting blade 20 can simultaneously cut the multiple wires located between the twisting member 03 and the fixed mold 11.

[0042] The energized melting assembly is mounted on the frame 01. It includes a positive electrode and a negative electrode. The two ends of a wire wound around the central shaft 19 and cut by the wire cutter 20 are electrically connected to the positive and negative electrodes, respectively. When the wire wound around the central shaft 19 is energized, it forms a closed circuit, causing the wire to short-circuit and heat up. The insulation layer on the surface of the wire melts due to the heat. Note that there are requirements for the energizing time, current, and voltage of the wires to ensure that the insulation layer of the multiple wires wound around the central shaft 19 melts slightly. This ensures that, on the one hand, after the insulation layer solidifies, the multiple wires can be fixed into a single unit, and the wound coil will not loosen after the moving mold 10 is reset; on the other hand, it also ensures that the areas of the multiple wires other than the ends are not electrically connected.

[0043] More specifically, the twisting assembly also includes a support frame 04 and a parallel guide groove wheel 05. The support frame 04 is mounted on the frame 01. There are two parallel guide groove wheels 05, both of which are rotatably mounted on the support frame 04. Multiple wires are simultaneously and sequentially wound around the two parallel guide groove wheels 05. The parallel guide groove wheels 05 enable multiple wires to be arranged side by side and close together. The twisting component 03 is rotatably mounted on the support frame 04.

[0044] The rotary drive mechanism 02 includes a motor 020, a synchronous pulley 021, a synchronous pulley 022, and a synchronous belt 023. The motor 020 is fixed on the support frame 04. The synchronous pulley 021 is coaxially fixed with the output shaft of the motor 020. The synchronous pulley 022 is fixed with the twisted wire component 03. The synchronous belt 023 is simultaneously fitted on the synchronous pulley 021 and the synchronous pulley 022. The motor 020 can drive the twisted wire component 03 to rotate stably.

[0045] More specifically, the twisting assembly also includes a first linear module 06, a second linear module 07, and a third linear module 08. The first linear module 06 is horizontally fixed to the frame 01. The second linear module 07 is horizontally fixed to the slider of the first linear module 06. The first linear module 06 can drive the second linear module 07 to move, and the direction of movement of the second linear module 07 relative to the first linear module 06 is the same as the length direction of the frame 01. The third linear module 08 is fixed to the slider of the second linear module 07. The second linear module 07 can drive the third linear module 08 to move, and the direction of movement of the third linear module 08 relative to the second linear module 07 is the same as the width direction of the frame 01. A support frame 04 is fixed to the slider of the third linear module 08. The third linear module 08 can drive the support frame 04 to move, and the direction of movement of the support frame 04 relative to the third linear module 08 is the same as the width direction of the frame 01. By designing linear modules 06 (first), 07 (second), and 08 (third), this design allows the support frame 04 and the twisting component 03 to move along the length and width of the frame 01, thus facilitating the adjustment of the twisting component 03's position. The sliders of both linear module 07 and linear module 08 move along the width of the frame 01. This design increases the travel distance of the twisting component 03 along the width of the frame 01. Furthermore, linear modules 07 and 08 can be controlled independently, meaning they can operate independently.

[0046] More specifically, the tangent assembly also includes linear module four 21, linear module five 22, linear module six 23, gripper cylinder one 24, movable block one 25, movable block two 26, clamping block one 27, and clamping block two 28. Linear module four 21 is horizontally fixed on the frame 01, and linear module five 22 is horizontally fixed on the slider of linear module four 21. Linear module four 21 can drive linear module five 22 to move, and the direction of movement of linear module five 22 relative to linear module four 21 is the same as the length direction of the frame 01. Linear module six 23 is horizontally fixed on the slider of linear module five 22, and linear module five 22 can drive linear module six 23 to move, and the direction of movement of linear module six 23 relative to linear module five 22 is the same as the width direction of the frame 01. Gripper cylinder 24 is horizontally fixed to the slider of linear module 6 23. Linear module 6 23 can drive gripper cylinder 24 to move. The direction of movement of gripper cylinder 24 relative to linear module 6 23 is the same as the width direction of frame 01. Movable block 1 25 and movable block 26 are each fixed to the two grippers of gripper cylinder 1 24. Movable block 1 25 is located above movable block 26. Both movable blocks 1 25 and movable block 26 are metal. Gripper cylinder 1 24 can drive movable blocks 1 25 and movable block 26 to move closer or further apart. Metal clamping block 27 is fixed to movable block 1 25 and the two are electrically connected. The lower end face of clamping block 27 has a triangular cross-section protrusion 270 integrally formed. Multiple protrusions 270 are provided and evenly arranged on the lower end face of clamping block 27. The metal clamping block 28 is fixed on the movable block 26. The upper surface of the clamping block 28 has a groove 280 that matches the shape and size of the protrusion 270. The gripper cylinder 24 can drive the clamping blocks 27 and 28 to move closer or further apart. The protrusion 270 can fit into the groove 280. Multiple wires can be arranged between the clamping blocks 27 and 28. The multiple wires are clamped between the protrusion 270 and the groove 280. The purpose of designing the protrusion 270 and the groove 280 is twofold: one is to ensure that the clamping blocks 27 and 28 can reliably and stably clamp the multiple wires; the other is that the edge of the protrusion 270 can further scratch the insulation layer of the multiple wires, which facilitates the subsequent energization of the wires and ensures that the wires can be energized smoothly, short-circuit and heat up to melt the insulation layer.

[0047] The wire cutter 20 is fixed to one side of the movable block 25. When the gripper cylinder 24 drives the movable block 25 and the second movable block 26 to move, the wire cutter 20 also moves vertically. When the wire cutter 20 moves downward, one side of the wire cutter 20 can slide and fit tightly against one side of the second movable block 26, thereby ensuring the cutting effect of the wire cutter 20 on the wire. The wire cutter 20 and the clamping block 27 are arranged sequentially along the length of the frame 01, with the wire cutter 20 located close to the twisting member 03.

[0048] By designing linear modules 21, 22, and 23, the positions of the wire cutter 20, clamping block 1 27, and clamping block 28 relative to the frame 01 can be adjusted. After the wire is wound, the wire cutter 20, clamping block 1 27, and clamping block 28 can be arranged between the fixed mold 11 and the twisting member 03, and multiple wires can be arranged between clamping block 1 27 and clamping block 2 28, thereby cutting the wire located between the fixed mold 11 and the twisting member 03.

[0049] More specifically, it also includes a lead wire assembly, which includes a linear module 7 32, a gripper cylinder 2 33, and a wire clamping component 34. The linear module 7 32 is horizontally fixed on the slider of the linear module 5 22. The linear module 5 22 can drive the linear module 7 32 to move. The direction of movement of the linear module 7 32 relative to the linear module 5 22 is the same as the width direction of the frame 01. The gripper cylinder 2 33 is horizontally fixed on the slider of the linear module 7 32. The linear module 7 32 can drive the gripper cylinder 2 33 to move. The direction of movement of the gripper cylinder 2 33 relative to the linear module 7 32 is the same as the width direction of the frame 01. Two clamping components 34 are provided, each fixed to the two jaws of the clamping cylinder 2 33. The two clamping components 34 are arranged vertically in sequence. The clamping cylinder 2 33 can drive the two clamping components 34 to move synchronously, that is, the two clamping components 34 can move closer or further apart, multiple wires can be arranged between the two clamping components 34, and the two clamping components 34 can clamp multiple wires together. Since the linear module 6 23 and the linear module 7 32 are both fixed on the slider of the linear module 5 22, the positions of the clamping components 34, the cutting blade 20, and the movable block 1 25 remain unchanged along the length of the frame 01, that is, the cutting blade 20 is located between the clamping component 34 and the movable block 1 25 along the length of the frame 01. By designing the linear module 4 21, the linear module 5 22, and the linear module 7 32, the clamping components 34 can move flexibly. Along the length of the frame 01, the clamping components 34 can move to the front or rear of the fixed mold 11. The ends of the multiple wires removed from the twisting member 03 can be clamped by two clamping members 34. The clamping members 34 can hold the multiple wires and move them so that the multiple wires are arranged between the moving mold 10 and the fixed mold 11, and between the mounting block 13 and the clamping block 15.

[0050] More specifically, it also includes an auxiliary paralleling assembly, which includes linear module 8 35, linear module 9 36, linear module 10 37, and a paralleling block 38. Linear module 8 35 is horizontally fixed on the frame 01. Linear module 9 36 is fixed on the slider of linear module 8 35. Linear module 8 35 can drive linear module 9 36 to move. The direction of movement of linear module 9 36 relative to linear module 8 35 is the same as the length direction of the frame 01. Linear module 10 37 is vertically fixed on the slider of linear module 9 36. Linear module 9 36 can drive linear module 10 37 to move. The direction of movement of linear module 10 37 relative to linear module 9 36 is the same as the width direction of the frame 01. The parallel block 38 is fixed on the slider of the linear module 37. The linear module 37 can drive the parallel block 38 to move. The direction of movement of the parallel block 38 relative to the linear module 37 is parallel to the axis of the fixed mold 11. The parallel block 38 is arranged between the fixed mold 11 and the twisting member 03.

[0051] The paralleling block 38 has a paralleling notch 380. The length direction of the paralleling notch 380 is perpendicular to the axis of the fixed mold 11, that is, the length direction of the paralleling notch 380 is the same as the width direction of the frame 01, or it can be said that the length direction of the paralleling notch 380 is the same as the length direction of the linear module 37. By designing the linear modules 35, 36, and 37, the paralleling block 38 can move along the length, width, and height directions of the frame 01. The paralleling block 38 moves so that multiple wires removed from the twisting member 03 and clamped and fixed by the clamping member 34 are arranged in the paralleling notch 380. Furthermore, the bottom of the paralleling notch 380 can press against the multiple wires along the width direction of the frame 01, so that the multiple wires are arranged sequentially and tightly along the length direction of the paralleling notch 380.

[0052] More specifically, it also includes a heat-setting assembly, which comprises a linear module 11 39, a linear module 12 40, and a heat-setting bar 41. Linear module 11 39 is horizontally fixed to the frame 01. Linear module 12 40 is fixed to the slider of linear module 11 39. Linear module 11 39 can drive linear module 12 40 to move. The direction of movement of linear module 12 40 relative to linear module 11 39 is the same as the length direction of the frame 01. Heat-setting bar 41 is fixed to the slider of linear module 12 40. Linear module 12 40 can drive heat-setting bar 41 to move. The direction of movement of heat-setting bar 41 relative to linear module 12 40 is parallel to the axis of the fixed mold 11. Through the design of linear modules 11 39 and 12 40, heat-setting bar 41 can move along the length and height directions of the frame 01. The length direction of heat-setting bar 41 is the same as the width direction of the frame 01. Heat-setting bar 41 heats up when energized.

[0053] When multiple wires are removed from the twisted wire member 03 and clamped and tightened by the clamping member 34 located between the twisted wire member 03 and the fixed mold 11, the heating rod 41 moves between the twisted wire member 03 and the clamping member 34. The side wall of the heating rod 41 will simultaneously contact the multiple wires. The heating rod 41 will burn through the insulation layer of the multiple wires located between the twisted wire member 03 and the clamping member 34, thereby ensuring that when the clamping block 15 and the mounting block 13 clamp the multiple wires, the area where the insulation layer of the multiple wires is burned through can contact the clamping block 15 and the mounting block 13 and be electrically connected, which facilitates the subsequent short circuit and heating of the multiple wires.

[0054] After the winding is completed, the heating rod 41 moves between the twisting member 03 and the fixed mold 11. The heating rod 41 will heat through the insulation layer of multiple wires located between the twisting member 03 and the fixed mold 11. Subsequently, the clamping block 1 27 and the clamping block 2 28 move so that the area where the insulation layer of the multiple wires is burned through will be clamped by the clamping block 1 27 and the clamping block 2 28. The area where the insulation layer of the multiple wires is burned through will make full contact with the clamping block 1 27 and be electrically conductive, which facilitates the subsequent short circuit and heating of the multiple wires.

[0055] The clamping components include a mounting block 13, a connecting rod 14, a clamping block 15, an abutment 16, a spring 17, and a telescopic component 18. The metal mounting block 13 is vertically fixed to one side of the fixed mold 11. A through hole is formed in the mounting block 13, with the center line of the hole parallel to the axis of the fixed mold 11. The metal connecting rod 14 is slidably inserted into the through hole, with its length parallel to the axis of the fixed mold 11. A metal clamping block 15 is fixed to one end of the connecting rod 14, and the abutment 16 is installed at the other end. The clamping block 15 is located above the mounting block 13, and the mounting block 13 and clamping block 15 cooperate to clamp multiple wires. The spring 17 is sleeved on the connecting rod 14, located below the mounting block 13, with both ends of the spring abutting against the mounting block 13 and the abutment 16, respectively. The telescopic component 2 18 is fixed on the frame 01. The telescopic component 2 18 and its telescopic end are located below the abutment component 16. The telescopic end of the telescopic component 2 18 can extend vertically and abut against the abutment component 16. The telescopic direction of the telescopic end of the telescopic component 2 18 is parallel to the axis of the fixed mold 11.

[0056] When the telescopic component 18 is not in motion, the spring 17 presses against the mounting block 13 and the abutment component 16 so that the clamping block 15 is elastically pressed against the mounting block 13.

[0057] When the telescopic component 18 is not in motion, its telescopic end will not contact the abutment 16, and the mounting block 13 and the abutment 16 can rotate with the fixed mold 11. When the clamping block 15 needs to move upward, the fixed mold 11 stops rotating, and the abutment 16 is vertically aligned with the telescopic end of the telescopic component 18. The telescopic end of the telescopic component 18 moves upward and pushes the abutment 16. The abutment 16 overcomes the elastic force of the spring 17 and moves upward, thereby separating the clamping block 15 from the mounting block 13.

[0058] More specifically, the electro-melting assembly also includes a telescopic component 29, a conductive component 30, and a controller 31. The telescopic component 29 is fixed to the frame 01, and the telescopic direction of its telescopic end is parallel to the axis of the fixed mold 11. The conductive component 30 is fixed to the telescopic end of the telescopic component 29 and is arranged below the mounting block 13. The telescopic component 29 can drive the conductive component 30 to move upward, so that the conductive component 30 abuts against the mounting block 13 and is electrically connected. The controller 31 is mounted on the frame 01. One output terminal of the controller 31 is the aforementioned positive electrode and is electrically connected to the clamping block 27, and the other output terminal of the controller 31 is a negative electrode and is electrically connected to the conductive component 30.

[0059] More specifically, it also includes a complete production line assembly, which includes a connecting shaft 42, a wire roller 43, a limiting member 44, and a wire guide wheel 45. The connecting shaft 42, wire roller 43, limiting member 44, wire guide wheel 05, twisting member 03, and fixed mold 11 are arranged sequentially along the length of the frame 01. The connecting shaft 42 is horizontally fixed on the frame 01, and the axis of the connecting shaft 42 is perpendicular to the length of the frame 01. Multiple wire guide wheels 45 are provided and are coaxially rotatably mounted on the connecting shaft 42. The multiple wire guide wheels 45 are arranged sequentially along the axial direction of the connecting shaft 42, and each wire guide wheel 45 has a wire wound on it. The wire roller 43 is rotatably mounted on the frame 01, and the axis of the wire roller 43 is parallel to the axis of the connecting shaft 42. Multiple wires simultaneously abut against the outer wall of the wire roller 43, and the wire roller 43 is located above the multiple wires. There are two limiting members 44, which are arranged sequentially along the length of the frame 01. The two limiting members 44 are located between the twisting member 03 and the wire roller 43. Each limiting member 44 includes two limiting strips 440 and two limiting bolts 441.

[0060] Two limiting strips 440 in the same limiting member 44 are sequentially fixed to the frame 01 vertically. The length direction of the limiting strip 440 is the same as the width direction of the frame 01. There is a wire passage gap between the two limiting strips 440 in the same limiting member 44, and multiple wires are arranged within the wire passage gap, sequentially along the length direction of the limiting strip 440. Two limiting bolts 441 in the same limiting member 44 are fixed to the limiting strip 440, sequentially along the length direction of the limiting strip 440. Multiple wires are arranged between the two limiting bolts 441 in the same limiting member 44. The wire passage gap and the limiting bolts 441 can gather and limit multiple wires from multiple wire guide wheels 45, ensuring that multiple wires can be sequentially arranged along the width direction of the frame 01. The wire passes sequentially through the wire guide wheel 45, the wire roller 43, the wire passage gap, the parallel guide wheel 05, and the twisting component 03.

[0061] More specifically, it also includes a transfer assembly, which comprises a telescopic component 46, a rotary cylinder 47, a support arm 48, a pneumatic suction cup 49, and a conveyor belt 50. The telescopic component 46 is vertically fixed to the frame 01, and is a cylinder. The rotary cylinder 47 is fixed to the telescopic end of the telescopic component 46, and is located above the telescopic component 46. The output shaft of the rotary cylinder 47 is vertically arranged. One end of the support arm 48 is fixed to the output shaft of the rotary cylinder 47, and the other end of the support arm 48 is fixed with the pneumatic suction cup 49, which is located below the support arm 48. The conveyor belt 50 is horizontally arranged on one side of the frame 01. The conveyor belt 50 is prior art, and its conveying direction is the same as the width direction of the frame 01. By designing the telescopic component 46 and the rotary cylinder 47, the pneumatic suction cup 49 can move between the moving mold 10 and the fixed mold 11 and pick up the wound coil located on the fixed mold 11. The pneumatic suction cup 49 with the coil can move above the conveyor belt 50 and release the coil so that the coil falls onto the conveyor belt 50.

[0062] A method for winding a wireless charging coil, the method comprising: First, one end of multiple wires passes through the twisting member 03 simultaneously and is clamped by two clamping members 34. Then, the paralleling block 38 actuates to arrange the multiple wires within the paralleling notch 380, the bottom of which presses against the multiple wires along the width of the frame 01, so that the multiple wires are arranged sequentially and tightly along the length of the paralleling notch 380. Next, the heating rod 41 actuates to heat through the insulation layer of the multiple wires located between the clamping member 34 and the twisting member 03. Finally, the clamping member 34 moves to arrange the multiple wires between the moving mold 10 and the fixed mold 11, and the clamping block 15 is located between the clamping member 34 and the fixed mold 11 along the length of the frame 01.

[0063] The second step involves first moving the clamping block 15 upwards; then moving the wire clamping member 34 to arrange multiple wires between the clamping block 15 and the mounting block 13; finally, moving the clamping block 15 downwards to reset, with the clamping block 15 and the mounting block 13 simultaneously clamping the multiple wires located between the moving mold 10 and the fixed mold 11, and the clamping block 15 simultaneously electrically connecting with the multiple wires; after the clamping block 15 moves downwards to reset, the two wire clamping members 34 no longer clamp the multiple wires.

[0064] The third step involves the telescopic component 109 moving the moving mold 10 down a set distance so that multiple wires simultaneously contact the moving mold 10 and the fixed mold 11. Note that the moving mold 10 and the fixed mold 11 only contact the wires and do not press them together. The multiple wires are arranged sequentially along the radial direction of the fixed mold 11.

[0065] In the fourth step, the rotary drive mechanism 12 drives the moving mold 10 and the fixed mold 11 to rotate synchronously. Multiple wires are wound around the central shaft 19 at the same time. For every 360° rotation of the moving mold 10, the rotary drive mechanism 102 drives the twisted wire component 03 to rotate 180°. After every 180° rotation, the twisted wire component 03 rotates in the opposite direction, and the cycle alternates.

[0066] Fifth step: First, after the multiple wires are wound around the central shaft 19 a rated number of times, the moving mold 10, the fixed mold 11, and the twisting component 03 stop rotating; at this time, the clamping block 15 is arranged between the fixed mold 11 and the twisting component 03 along the length of the frame 01; second, the heating rod 41 is activated, and the heating rod 41 heats up the insulation layer of the multiple wires located between the fixed mold 11 and the twisting component 03; next, the cutting blade 20 and the clamping block 1 27 are activated, so that the area where the insulation layer of the multiple wires is heat-broken is arranged between the clamping block 1 27 and the clamping block 28; finally, the gripper cylinder 1 24 drives the clamping block 1 27, the clamping block 28, and the cutting blade 20 to move, the clamping block 1 27 and the clamping block 28 clamp the multiple wires, and the cutting blade 20 cuts the multiple wires located between the clamping block 1 27 and the twisting component 03.

[0067] In the sixth step, the telescopic component 29 moves the conductive component 30 upward so that the conductive component 30 abuts against the mounting block 13 and is electrically connected; the controller 31 is energized, and the two ends of the multiple wires wound on the central shaft 19 are electrically connected to the positive and negative electrodes for a set time. The multiple wires wound on the central shaft 19 are energized and short-circuited to generate heat, so that the insulation layer on the surface of the wires melts. The multiple wires wound on the central shaft 19 are fixed together by the cooled insulation layer after melting.

[0068] Step 7: The telescopic component 109 moves the moving mold 10 upward and resets it. The pneumatic suction cup 49 moves between the moving mold 10 and the fixed mold 11 and adsorbs the coil formed by winding multiple wires. The pneumatic suction cup 49 with the coil adsorbed moves above the conveyor belt 50 and releases the coil.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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 still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
