Description

Technical Field

[0001] This specification relates to the field of automatic winding technology, and more particularly to a winding device. Background Technology

[0002] In the production of electronic components such as motors, transformers, and inductors, the winding device is one of the core pieces of equipment, used to neatly and tightly wind wires (such as enameled wire) onto a frame. With the continuous improvement of production efficiency requirements, multi-station winding devices have gradually become the industry mainstream. They typically employ multiple winding stations operating simultaneously or alternately to increase output per unit time.

[0003] In existing multi-station winding devices, the layout of the winding assembly and the transfer assembly (used to remove the wound coil) is relatively simple. A common structure places the transfer assembly above or inside the winding assembly, requiring the operator to cross the winding assembly or retrieve the coil from a narrow space. This layout presents several problems: First, movement interference easily occurs between the transfer assembly and the winding assembly. To ensure smooth retrieving, the winding assembly structure often needs to be complexly designed, such as adding an extra obstacle avoidance mechanism to the upper die or an ejection mechanism to the lower die, resulting in a bulky equipment structure and increased costs. Second, the main working areas of the winding assembly (upper die, lower die, and winding position) are easily obstructed by the transfer assembly or other structures, making it difficult for operators to directly observe the coil forming process. When winding faults occur (such as broken wire, overlapping wire, or die jamming), a large number of peripheral components need to be disassembled for repair, making maintenance extremely inconvenient and severely impacting the production line's uptime.

[0004] Furthermore, in multi-station winding devices, how to rationally allocate the time between the winding process and the material handling process to achieve parallel operation and avoid prolonged idleness of the winding components due to material handling is a technical challenge that continues to concern those skilled in the art. Traditional solutions often adopt a serial operation mode of "winding completion - shutdown - material handling - restart", or require a separate material handling mechanism for each winding component. The former is inefficient, while the latter significantly increases equipment costs and floor space.

[0005] Therefore, how to simplify the structure of the winding assembly and improve the observability and maintainability of the equipment while ensuring the efficient operation of the multi-station winding device has become an urgent technical problem to be solved in this field.

[0019] Beneficial effects:

[0020] The winding device provided in this embodiment has four winding assemblies and two transfer assemblies. While ensuring efficient multi-station operation, it simplifies the structure of the winding assemblies and improves the observability and maintainability of the equipment. Specifically, compared with the prior art, this winding device has the following advantages:

[0021] 1. Optimized layout for easy observation and maintenance: By placing four winding assemblies at the four vertices of a rectangle, all facing outwards, and positioning two transfer assemblies on either side of the winding assemblies, while limiting the mounting base and transfer assemblies to be located on either side of the upper die in the second direction, the upper and lower dies of the winding assemblies are fully exposed to the outside of the equipment. During normal operation, operators can directly observe the coil forming process from the outside without the need for additional tools or climbing equipment. In the event of a winding fault (such as wire breakage, wire overlap, or die jamming), because the winding assemblies are facing outwards and unobstructed, maintenance personnel can directly disassemble and repair the faulty workstation from the outside without removing the transfer assemblies or other external structures, significantly reducing maintenance difficulty and downtime, and improving the maintainability of the equipment.

[0022] 2. The transfer assembly is rationally laid out, achieving spatial avoidance and preventing motion interference: By setting the height of the first slide rail to be lower than the height of the upper surface of the lower die, and combining this with the layout of the transfer assembly outside the winding assembly, the movement trajectory of the material take-up unit along the first direction, the second direction, and the vertical direction is entirely below and outside the winding assembly, preventing interference with the upper die, the lower die, or the coil being wound. This spatial avoidance design ensures that the transfer assembly and the winding assembly can work independently and in parallel, eliminating the need for complex avoidance mechanisms for the winding assembly, simplifying the equipment structure, and improving operational stability and reliability.

[0023] 3. Simplified winding assembly structure and reduced manufacturing costs: In this solution, the transfer assembly integrates material handling and multi-directional transfer functions in the first, second, and vertical directions, enabling it to actively move to the winding assembly position to complete material handling. Therefore, the winding assembly itself does not require an ejection mechanism or a complex lower mold lifting mechanism; the upper mold only needs to have the freedom to move up and down along the fourth slide rail to meet the basic requirements of winding and demolding. This functional division greatly simplifies the structure of the winding assembly, reduces the number of parts and assembly complexity, lowers manufacturing costs, and also helps improve the operating accuracy and stability of the winding assembly itself.

[0024] 4. Achieving parallel winding and material handling operations to improve production efficiency: By placing two transfer components on either side of the winding component, each transfer component corresponds to two winding components spaced apart in the first direction, and adopting an alternating operation mode—when one winding component is performing the winding process, the other winding component cooperates with the transfer component to perform the transfer process, allowing the winding and material handling actions to be performed simultaneously. Compared with the traditional serial operation mode, this solution effectively eliminates the waiting time during the material handling process, maximizes equipment utilization, and significantly improves the overall production efficiency of the multi-station winding device.

[0025] 5. Compact layout and high space utilization: The four winding assemblies are arranged in a rectangular shape at the four corners, and the two transfer assemblies are located on both sides of the winding assemblies. The overall structure is compact and symmetrical, integrating four winding stations and two transfer stations within a limited space. At the same time, by setting the height of the first slide rail below the upper surface of the lower die, the space below the winding assemblies is fully utilized, avoiding the transfer assemblies occupying additional upper space. This results in a small footprint and high space utilization for the entire equipment, facilitating its connection and layout with other equipment in the production line.

[0059] Please see Figures 1 to 20 This application provides a winding device, including: four winding assemblies 9 and two transfer assemblies 7.

[0060] Among them, such as Figure 1 and Figure 2 As shown, four winding assemblies 9 are located at the four vertices of a rectangle. The adjacent sides of the rectangle extend along the first direction X and the second direction Y, respectively. Two transfer assemblies 7 are located on either side of the four winding assemblies 9 along the second direction Y, with each transfer assembly 7 corresponding to two winding assemblies 9 spaced apart along the first direction X. The two winding assemblies 9 spaced apart along the first direction X face the same direction, while the two winding assemblies 9 spaced apart along the second direction Y face opposite directions (both facing the transfer assembly 7, i.e., outwards).

[0061] like Figure 7 As shown, the winding assembly 9 includes a fixed mounting base 98 and a lower die 92 and an upper die 91 aligned vertically in the Z direction. The lower die 92 and the upper die 91 can rotate synchronously around the vertical axis to perform winding. The first direction X, the second direction Y, and the vertical direction Z are mutually perpendicular, that is, the first direction X and the second direction Y are two mutually perpendicular directions in the horizontal plane.

[0062] like Figure 4 and Figure 11 As shown, the transfer assembly 7 includes: a first slide rail 11 extending along a first direction X; a first connecting seat 21 slidably connected to the first slide rail 11; a second slide rail 12 extending along a second direction Y and disposed on the first connecting seat 21; a second connecting seat 22 slidably connected to the second slide rail 12; a third slide rail 13 extending along a vertical direction Z and disposed on the second connecting seat 22; a third connecting seat 23 slidably connected to the third slide rail 13; and a material-taking part 3 fixedly disposed at the bottom of the third connecting seat 23. The material-taking part 3 is used to take out the coil after winding in the winding assembly 9.

[0063] like Figure 7 As shown, the lower mold 92 is connected to the bottom end of the mounting base 98. Near the top of the mounting base 98, a fourth slide rail 99 extending vertically in the Z direction is provided, and the upper mold 91 is slidably connected to the fourth slide rail 99. The fourth slide rail 99 and the transfer assembly 7 are located on different sides of the upper mold 91 in the second direction Y to make efficient use of space. For two winding assemblies 9 spaced apart in the first direction X, when one winding assembly 9 performs a winding process, the other winding assembly 9 cooperates with the transfer assembly 7 to perform a transfer process. Figure 1 As shown, for a corresponding transfer component 7 and two winding components 9, the mounting base 98 and the transfer component 7 are located on both sides of the upper mold 91 in the second direction Y. All four winding components 9 are arranged outwards, and the height of the first slide rail 11 is lower than the height of the upper surface of the lower mold 92.

[0064] The winding device provided in this embodiment has four winding assemblies 9 and two transfer assemblies 7. While ensuring efficient multi-station operation, it simplifies the structure of the winding assemblies 9 and improves the observability and maintainability of the equipment. Specifically, compared with the prior art, this winding device has the following beneficial effects:

[0065] 1. Optimized layout for easier observation and maintenance: By placing four winding assemblies 9 at the four vertices of a rectangle, all facing outwards, and placing two transfer assemblies 7 on both sides of the winding assembly 9, while limiting the mounting base 98 and transfer assemblies 7 to be positioned on both sides of the upper mold 91 in the second direction Y, the upper mold 91 and lower mold 92 of the winding assembly 9 are fully exposed to the outside of the equipment. During normal operation, operators can directly observe the coil forming status during the winding process from the outside without the need for additional tools or climbing equipment. When a winding fault occurs (such as wire breakage, wire overlap, or mold jamming), because the winding assembly 9 faces outwards and has no external obstructions, maintenance personnel can directly disassemble and repair the faulty station from the outside without removing the transfer assembly 7 or other external structures, significantly reducing maintenance difficulty and downtime, and improving the maintainability of the equipment.

[0066] 2. The transfer assembly 7 is rationally laid out, achieving spatial avoidance and preventing motion interference: By setting the height of the first slide rail 11 to be lower than the height of the upper surface of the lower die 92, and combined with the layout of the transfer assembly 7 located outside the winding assembly 9, the movement trajectory of the material take-up part 3 along the first direction X, the second direction Y, and the vertical direction Z is completely located below and outside the winding assembly 9, without interfering with the upper die 91, the lower die 92, or the coil being wound. This spatial avoidance design ensures that the transfer assembly 7 and the winding assembly 9 can work independently and in parallel, eliminating the need for a complex avoidance mechanism for the winding assembly 9, simplifying the equipment structure, and improving operational stability and reliability.

[0067] 3. Simplified structure of winding assembly 9, reducing manufacturing costs: In this solution, the transfer assembly 7 integrates material handling function and multi-directional transfer function in the first direction X, the second direction Y, and the vertical direction Z, and can actively move to the position of winding assembly 9 to complete material handling. Therefore, winding assembly 9 itself does not need to be equipped with an ejection mechanism or a complex lower mold 92 lifting mechanism. The upper mold 91 only needs to have the degree of freedom to move up and down along the fourth slide rail 99 to meet the basic requirements of winding and demolding. This functional division greatly simplifies the structure of winding assembly 9, reduces the number of parts and assembly complexity, lowers manufacturing costs, and also helps to improve the operating accuracy and stability of winding assembly 9 itself.

[0068] 4. Achieving parallel winding and material handling operations to improve production efficiency: By distributing two transfer components 7 on either side of the winding component 9, each transfer component 7 corresponds to two winding components 9 spaced apart in the first direction X, and employing an alternating operation mode—when one winding component 9 is performing the winding process, the other winding component 9 cooperates with the transfer component 7 to perform the transfer process, allowing the winding and material handling actions to be performed simultaneously. Compared to the traditional serial operation mode, this solution effectively eliminates the waiting time during the material handling process, maximizes equipment utilization, and significantly improves the overall production efficiency of the multi-station winding device.

[0069] 5. Compact layout and high space utilization: The four winding assemblies 9 are arranged in a rectangular shape at the four corners, and the two transfer assemblies 7 are located on both sides of the winding assemblies 9. The overall structure is compact and symmetrical, integrating four winding stations and two transfer stations within a limited space. At the same time, by setting the height of the first slide rail 11 below the upper surface of the lower mold 92, the space below the winding assemblies 9 is fully utilized, avoiding the transfer assemblies 7 occupying additional upper space. This results in a small footprint and high space utilization for the entire equipment, facilitating connection and layout with other equipment in the production line.

[0070] In this embodiment, the winding device further includes four wire feeding assemblies 8, each corresponding to one of the four winding assemblies 9. The wire feeding assemblies 8 are located on one side of the winding assemblies 9 in the first direction X. Figure 4 and Figure 5 As shown, the wire feeding assembly 8 includes a wire storage box 81, a wire feeding wheel assembly 82, a first mounting plate 83, a wire feeding clamp 84, and a cutter 85. The wire storage box 81 is used to store wires, and its top has a through hole for the wires to pass through. After the wires pass through the wire storage box 81, they receive appropriate tension through the wire feeding wheel assembly 82, and are then clamped by the wire feeding clamp 84 and fed into the subsequent winding assembly 9. The wire feeding clamp 84 and the cutter 85 are mounted on the first mounting plate 83. The first mounting plate 83 is connected to a first driving member 86 and a second driving member 87, which are used to drive the first mounting plate 83 to move in the vertical direction Z and the first direction X, respectively. Thus, the wire feeding clamp 84 and the cutter 85 can move in the vertical direction Z and the first direction X to realize the transfer of wires.

[0071] Specifically, such as Figure 15As shown, the material handling unit 3 includes a horizontally arranged material handling surface 31, a material handling block 32 protruding from the material handling surface 31, and a first suction hole 33 disposed on the material handling surface 31 and located around the material handling block 32. The transfer assembly 7 also includes a push block 4 slidably disposed at the bottom of the third connecting seat 23. The push block 4 and the material handling block 32 are aligned and spaced apart in the second direction Y. This material handling unit 3 has a unique structure, ensuring stable material handling without damaging the workpiece. The material handling unit 3 adopts a composite structure of "horizontal material handling surface 31 + protruding material handling block 32 + first suction hole 33", and uses the push block 4 for auxiliary fixation. The material handling block 32 is used to extend into the coil, and the first suction hole 33 uses negative pressure adsorption to pick up and fix the coil. The push block 4 and the material handling block 32 can gently clamp one side of the coil to prevent the coil from falling due to vacuum failure. This combination of "adsorption + auxiliary fixation" avoids the squeezing damage to the coil enameled wire caused by pure gripper-type material handling, and overcomes the deficiency of insufficient fixing force of pure suction cup-type material handling, thus achieving gentle and stable gripping of the coil.

[0072] In this embodiment, such as Figure 13 As shown, the bottom of the third connecting seat 23 is provided with a fifth slide rail 14 extending along the second direction Y. A first connecting plate 761 is slidably connected below the fifth slide rail 14. The push block 4 is connected to the end of the first connecting plate 761 away from the third slide rail 13. The first connecting plate 761 can drive the push block 4 to move along the second direction Y on the fifth slide rail 14 to approach or move away from the material picking block 32.

[0073] like Figure 14 As shown, the first connecting plate 761 is provided with a sixth slide rail 15 extending along the second direction Y. A second connecting plate 762 is slidably connected below the sixth slide rail 15. A push block 4 is fixedly connected to the end of the second connecting plate 762 opposite to the third slide rail 13. A spring 764 is provided between the second connecting plate 762 and the first connecting plate 761, so that the second connecting plate 762 and the first connecting plate 761 are elastically slidably connected, avoiding excessive pressure on the coil by the push block 4.

[0074] like Figure 4 As shown, the wire storage box 81 is located on the side of the first mounting plate 83 away from the transfer assembly 7 in the second direction Y. Specifically, the wire feeding wheel assembly 82 includes: a first wire feeding wheel 821 disposed above the wire storage box 81, a second wire feeding wheel 822 disposed above the first wire feeding wheel 821, and a third wire feeding wheel 823 disposed on the first mounting plate 83. Of course, the wire feeding wheel assembly 82 may also include other wire feeding wheels, such as a fourth wire feeding wheel 824 disposed between the first wire feeding wheel 821 and the second wire feeding wheel 822. The third wire feeding wheel 823, the wire feeding clamp 84, the cutter 85, and the lower die 92 are aligned in the first direction X to improve wire feeding efficiency.

[0075] like Figure 10As shown, the lower mold 92 is fixedly connected to a wire-starting clamp 93 and a wire-ending clamp 94. A wire-feeding clamp 84 cooperates with the wire-starting clamp 93, allowing the wire to be fed to the wire-starting clamp 93. A cutter 85 cooperates with the wire-ending clamp 94, cutting the wire at the wire-ending clamp 94. The lower mold 92 has a retractable core 95 at its center. During winding, the core 95 extends to support the coil frame; after winding, the core 95 retracts, creating a gap between the coil and the mold, facilitating the removal of the coil by the material-taking section 3 of the transfer assembly 7. This design further reduces the difficulty of material removal and avoids material removal failure or coil deformation caused by excessive tightness between the coil and the mold. The upper mold 91 is connected to a third driving component 96, which drives the upper mold 91 to move vertically in the Z direction to approach or move away from the lower mold 92, enabling winding or coil removal operations.

[0076] Specifically, the fixed end of the third driving component 96 is fixedly installed on the top of the mounting base 98, and the driving end is connected to the upper mold 91, thereby driving the upper mold 91 to move vertically along the fourth slide rail 99. The transfer assembly 7 also includes a first clamping component 51 and a second clamping component 52 disposed on the third connecting base 23. The first clamping component 51 and the second clamping component 52 are used to clamp the starting wire and the tail wire in the starting wire clamp 93 and the tail wire clamp 94, respectively. The material picking part 3, the push block 4, the first clamping component 51, and the second clamping component 52 are all integrated and disposed at the bottom and around the third connecting base 23. All functional components share the same motion platform, realizing a high degree of coordination of the "material picking-pushing-wire clamping" action. This integrated design not only reduces the overall size of the mechanism and simplifies the control logic, but also effectively avoids the risk of motion interference that may be caused by the dispersed arrangement of multiple components.

[0077] In this embodiment, the wire feeding assembly 8 and the winding assembly 9 work precisely together to achieve automatic wire end transfer. By setting the starting wire clamp 93 and the ending wire clamp 94 to be fixed to the lower mold 92, and having the wire feeding clamp 84 and the cutter 85 respectively cooperate with them, precise handover of the wire end is achieved. After the wire feeding assembly 8 completes the wire feeding, it can accurately hand the wire end to the starting wire clamp 93 on the winding assembly 9, ensuring that the starting end of the winding is stably fixed; after the winding is completed, the cutter 85 cuts off the wire end at the ending wire clamp 94, and the first clamp 51 and the second clamp 52 of the transfer assembly 7 take over the wire end from the starting wire clamp 93 and the ending wire clamp 94 respectively, realizing automatic wire end management throughout the entire process from wire feeding to winding to transfer, avoiding manual intervention and wire end loosening problems.

[0078] The transfer assembly 7 integrates material picking and wire clamping functions, enabling simultaneous processing of coils and wire ends. The transfer assembly 7 employs a three-stage orthogonal slide rail system (first direction X, second direction Y, and vertical direction Z) to achieve precise positioning in three-dimensional space. By setting up a first slide rail 11, a second slide rail 12, and a third slide rail 13 perpendicular to each other along the first direction X, the second direction Y, and the vertical direction Z, and in conjunction with the first connecting seat 21, the second connecting seat 22, and the third connecting seat 23, a complete triaxial orthogonal transfer system is constructed. This structure allows the material picking unit 3 to move freely and precisely in the X, Y, and Z directions, flexibly adapting to the material picking and placing needs of different workstations and heights, significantly improving the equipment's versatility and positioning accuracy. Simultaneously, it simplifies the structure of the upstream winding assembly 9, eliminating the need for the winding assembly 9 to have multiple degrees of freedom. The material picking unit 3, the first clamping member 51, and the second clamping member 52 are simultaneously located at the bottom of the third connecting seat 23, allowing the transfer assembly 7 to simultaneously clamp the starting and ending wires while picking up the coil body. This integrated design of material handling and wire clamping not only reduces the cycle time and improves efficiency, but also ensures that the wire end is always under control during the coil transfer process, providing accurate positioning of the wire end for subsequent processes.

[0079] In this embodiment, the wire feeding assembly 8, winding assembly 9, and transfer assembly 7 are rationally distributed along the first direction X and the second direction Y (the wire feeding assembly 8 and winding assembly 9 are adjacent in the first direction X, and the transfer assembly 7 is adjacent to the winding assembly 9 in the second direction Y), forming an "L-shaped" or "T-shaped" compact layout. Each module maintains independent operation while shortening the material flow path through spatial optimization, reducing the overall size of the machine, resulting in a compact spatial layout and a small footprint.

[0080] like Figure 12 As shown, a third connecting plate 763 is fixedly connected to the top of the third connecting seat 23, and the first clamping member 51 and the second clamping member 52 are both connected to the third connecting plate 763. This application does not impose a unique limitation on the shape of the third connecting plate 763. Preferably, the third connecting plate 763 is annular.

[0081] Specifically, the third connecting plate 763 is provided with a plurality of mounting holes 7631 spaced apart in the circumferential direction. The first clamping member 51 and the second clamping member 52 are respectively connected to two of the mounting holes 7631, thereby allowing for quick adjustment of the positions of the first clamping member 51 and the second clamping member 52. Preferably, the center of the material picking block 32 is aligned with the center of the third connecting plate 763 in the vertical direction Z.

[0082] The shape of the material-taking block 32 is not uniquely limited in the embodiments of this application; the shape of the material-taking block 32 can be designed according to the shape of the coil to be taken. For example... Figure 15As shown, the material receiving block 32 is rectangular. Correspondingly, there are four first suction holes 33, located around the perimeter of the material receiving block 32.

[0083] Specifically, the first suction hole 33 located on the short side of the material picking block 32 is circular, and the first suction hole 33 located on the long side of the material picking block 32 is rectangular, in order to better pick up the coil. For example... Figure 9 As shown, the shape of the mold core 95 is the same as the shape of the material taking block 32. During material taking, the bottom surface of the material taking block 32 is aligned and in contact with the top surface of the mold core 95, and the material taking block 32 and the mold core 95 move downward synchronously.

[0084] In this embodiment, the length of the first slide rail 11 is greater than the length of the second slide rail 12, and the length of the first slide rail 11 is greater than the length of the third slide rail 13. The second slide rail 12 and the third slide rail 13 are used to assist the material handling unit 3 in quickly picking up parts, and the first slide rail 11 is used to transfer the coil from the winding station to the next station.

[0085] like Figure 5 and Figure 6 As shown, the wire feeding assembly 8 includes a second mounting plate 88. The output end of the first driving member 86 is connected to the second mounting plate 88, thereby driving the second mounting plate 88 to move in the vertical direction Z. The second mounting plate 88 is provided with a seventh slide rail 89 extending in the first direction X. The first mounting plate 83 is slidably connected to the seventh slide rail 89. The output end of the second driving member 87 is connected to the first mounting plate 83, thereby driving the first mounting plate 83 to move in the first direction X.

[0086] Furthermore, the first mounting plate 83 is provided with an eighth slide rail 810 extending along the first direction X. A mounting block 811 is slidably connected to the eighth slide rail 810. A wire feeding clamp 84 and a cutter 85 are mounted on one end of the mounting block 811 facing the winding assembly 9 in the first direction X, so that the mounting block 811 can drive the wire feeding clamp 84 and the cutter 85 to move relative to the third wire feeding wheel 823 along the first direction X. A wire feeding clamp plate 812 is fixedly provided on one end of the first mounting plate 83 facing the winding assembly 9 in the first direction X, for managing the wire between the third wire feeding wheel 823 and the wire feeding clamp 84.

[0087] In this embodiment, the cutter 85 is movable relative to the mounting block 811 in the first direction X, thereby cutting the wire. For example... Figure 10 As shown, the bottom of the tail clamp 94 has a stepped surface 941 for engaging with the cutter 85. The wire feed clamp 812 is located below the wire feed holder 84, and the cutter 85 is located above the wire feed holder 84, so that when the cutter 85 cuts the wire, the wire feed holder 84 can hold the wire end, preventing the wire from suddenly coming loose. A baffle 813 may also be provided above the cutter 85 for abutting against the starting clamp 93 or the tail clamp 94 for easy positioning. The baffle 813 can be fixedly connected to the mounting block 811.

[0088] Specifically, the lower mold 92 is fixedly connected to the fourth connecting plate 97, and the center of the lower mold 92 and the center of the fourth connecting plate 97 are aligned in the vertical direction Z. The starting clamp 93 and the ending clamp 94 are respectively connected to different positions on the circumference of the fourth connecting plate 97 and their positions are adjustable. Correspondingly, the positions of the first clamping member 51 and the second clamping member 52 on the third connecting plate 763 are also adjustable.

[0089] Preferably, the winding assembly 9 further includes a hot air gun 910 slidably connected to the mounting base 98. The hot air gun 910 is positioned between the upper mold 91 and the lower mold 92 to heat the coil, thereby making the coil structure more stable. The upper mold 91 is connected to a sixth driving member 911 for driving the upper mold 91 to rotate around a vertical axis. The lower mold 92 is connected to a seventh driving member 912 for driving the lower mold 92 to rotate around a vertical axis. The sixth driving member 911 and the seventh driving member 912 operate synchronously in the same direction to ensure that the upper mold 91 and the lower mold 92 rotate synchronously around the vertical axis.

[0090] like Figure 8 As shown, the top side of the lower mold 92 is also provided with a wire groove 921 to introduce the wire end. In a specific application scenario, the wire starts from the wire storage box 81, passes through the first wire feeding wheel 821, the second wire feeding wheel 822, the third wire feeding wheel 823, and the wire feeding clamp 812 in sequence, and arrives at the wire feeding clamp 84. Driven by the first drive member 86 and the second drive member 87, the wire feeding clamp 84 smoothly feeds the wire end into the wire lifting clamp 93. At this time, it ensures that the upper mold 91 and the lower mold 92 are in contact and the mold core 95 is extended. Driven by the sixth drive member 911 and the seventh drive member 912, the wire lifting clamp 93 drives the wire end to rotate. When it reaches a certain angle, the wire end enters the wire groove 921. The upper mold 91 and the lower mold 92 continue to rotate, and the wire is wound into a coil on the mold core 95. After the coil is wound, the wire feeding clamp 84 feeds the tail wire into the tail wire clamp 94 and cooperates with the stepped surface 941 of the tail wire clamp 94 to cut the tail wire with the cutter 85. Subsequently, the upper mold 91 moves upward, and the material-taking part 3 of the transfer assembly 7 moves to above the lower mold 92. After the material-taking block 32 and the mold core 95 come into contact, they move downward synchronously, so that the coil is transferred from the mold core 95 to the material-taking block 32. The first clamping member 51 clamps the starting wire in the wire clamp 93, and the second clamping member 52 clamps the tail wire in the tail wire clamp 94. The push block 4 moves to the position of contacting the coil. Then, the material-taking part 3 drives the coil to move along the vertical direction Z, the second direction Y and the first direction X, and moves the coil to the next station (i.e. the wire-arranging station at the wire-arranging assembly 6 mentioned below).

[0091] In this embodiment, the winding device further includes two wire management components 6, each corresponding to one of the two transfer components 7. The wire management component 6 is located near the end of the first slide rail 11 furthest from the winding component 9, and is situated on the same side of the first slide rail 11 as the winding component 9 in the second direction Y. Figure 3 As shown, in the first direction X, on the same side of the first slide rail 11, there are sequentially arranged wire feeding assembly 8, wire winding assembly 9, wire feeding assembly 8, wire winding assembly 9 and wire management assembly 6.

[0092] like Figures 16 to 20 As shown, the cable management assembly 6 includes a carrier 65, a first stop block 611, and a second stop block 612. Figure 18 As shown, the first stop 611 and the second stop 612 are located on the same side of the carrier 65 in the first direction X, and are used to push the starting and ending wires of the coil, respectively. The first stop 611 and the second stop 612 have a degree of freedom in the second direction Y, and can move closer or further apart from each other in the second direction Y. By actively adjusting the wire end angle through the first stop 611 and the second stop 612, precise alignment can be achieved. When the stops push the starting and ending wires, by controlling the moving distance and relative position of the stops, the starting and ending wires can be adjusted to the preset required angle. This active angle adjustment structure ensures that the wire end is calibrated to an ideal posture before entering the clamping device, providing a reliable guarantee for precise docking with the next station and avoiding alignment failure caused by wire end angle deviation.

[0093] like Figure 20 As shown, the carrier 65 includes a bearing surface 651 and a receiving hole 652 disposed on the bearing surface 651. A bearing block 653, movable in the vertical Z direction to extend or retract from the bearing surface 651, is provided within the receiving hole 652. The bearing surface 651 is used to support the coil. When the bearing block 653 extends out of the bearing surface 651, it extends into the coil (such as the center hole of the coil frame or the inner cavity of the coil), providing stable support and positioning for the coil body, effectively preventing displacement or rotation of the coil when the stop block pushes the wire end. After the wire is arranged, the bearing block 653 retracts into the bearing surface 651, facilitating the removal of the coil. This retractable positioning structure ensures the stability of the coil's posture during wire arrangement without affecting the loading and unloading operations, achieving a balance between positioning function and passability. A second suction hole 655 can also be provided around the receiving hole 652 on the bearing surface 651 to generate negative pressure to attract the coil, further fixing it in place.

[0094] Specifically, the cable management assembly 6 also includes a third clamping member 631 and a fourth clamping member 621 located on the side of the first stop 611 and the second stop 612 away from the carrier 65 in the first direction X, respectively for clamping the starting and ending ends of the cable away from the coil. The third clamping member 631 is connected to the periphery of the first rotating shaft 632, and the fourth clamping member 621 is connected to the periphery of the second rotating shaft 622. The axes of the first rotating shaft 632 and the second rotating shaft 622 coincide, and the dimensions of the first rotating shaft 632 and the second rotating shaft 622 are different, so that the clamping members can rotate with the rotating shafts to realize the angle adjustment of the cable end in space. A fourth driving member 633 and a ninth slide rail 634 extending vertically in the Z direction are connected between the third clamping member 631 and the first rotating shaft 632. The fourth driving member 633 drives the third clamping member 631 to move relative to the first rotating shaft 632 on the ninth slide rail 634 to ensure that the heights of the third clamping member 631 and the fourth clamping member 621 are staggered to avoid interference. This combined rotation and lifting motion structure allows the clamping member to flexibly adjust the spatial posture of the wire end according to the interface direction of the next station after clamping the wire end, realizing a smooth transition of the wire end from the wire sorting station to the subsequent station, improving the versatility and automation of the equipment.

[0095] The axes of the first rotating shaft 632 and the second rotating shaft 622 coincide but have different dimensions, resulting in the two clamping components having different rotation radii during rotation. This design fully considers the positional differences between the starting and ending wires on the coil—the two wire ends are usually located on different sides of the coil or have different extension lengths. The clamping components with different rotation radii can adapt to the actual spatial positions of the starting and ending wires respectively, achieving their own independent optimized wire management trajectories, and avoiding problems such as wire end interference or insufficient wire management caused by the same rotation radius.

[0096] This application arranges the wire end angle adjustment function (first stop 611 and second stop 612) and the wire end clamping function (third clamping member 631 and fourth clamping member 621) sequentially along the first direction X, forming a clear process route of "first sorting the wire, then clamping". After the stop completes the angle adjustment, the clamping member can directly clamp the sorted wire end in the same work area without intermediate transfer. This layout simplifies the mechanism design, shortens the action cycle, improves production efficiency, and makes the wire sorting and clamping functions clearly separated and highly efficient.

[0097] The wire management assembly 6 provided in this embodiment arranges the carrier 65, the stop block, and the clamping rotation module sequentially along the first direction X. Each functional module has clear boundaries and independent operation, facilitating programming, debugging, and subsequent maintenance of the control system. Simultaneously, the compact spatial arrangement of the modules effectively reduces the equipment's footprint, making it easy to integrate into automated production lines. The compact structure and high degree of modularity enable stable and rapid handling and clamping of the starting and ending wires of the coil.

[0098] In this embodiment, such as Figure 18 As shown, the cable management assembly 6 also includes a fixedly mounted third mounting plate 61, and the carrier 65 is fixedly connected to the upper surface of the third mounting plate 61. The third mounting plate 61 is provided with a tenth slide rail 613 and an eleventh slide rail 614 extending along the second direction Y. A first stop block 611 is slidably connected to the tenth slide rail 613, and a second stop block 612 is slidably connected to the eleventh slide rail 614, thereby facilitating the movement of the first stop block 611 and the second stop block 612 along the second direction Y.

[0099] Specifically, the tenth slide rail 613 and the eleventh slide rail 614 are aligned in the second direction Y and are both located on the side of the carrier 65 in the first direction X that is away from the first stop 611 and the second stop 612, making reasonable use of the space on the third mounting plate 61.

[0100] Furthermore, the first stop 611 is slidably connected to the tenth slide rail 613 via the first connecting arm 615, which connects the first stop 611 and the tenth slide rail 613 located on different sides of the vehicle 65. The second stop 612 is slidably connected to the eleventh slide rail 614 via the second connecting arm 616, which connects the second stop 612 and the eleventh slide rail 614 located on different sides of the vehicle 65. Figure 19 As shown, the tenth slide rail 613, the first connecting arm 615, the first stop block 611, the second stop block 612, the second connecting arm 616, and the eleventh slide rail 614 are distributed sequentially in the circumferential direction of the carrier 65, with a compact and reasonable layout.

[0101] In this embodiment, the first connecting arm 615 is connected to an eighth driving member 617, which drives the first connecting arm 615 to move the first stop 611 along the tenth slide rail 613. The second connecting arm 616 is connected to a ninth driving member 618, which drives the second connecting arm 616 to move the second stop 612 along the eleventh slide rail 614. Both the eighth driving member 617 and the ninth driving member 618 are disposed on the third mounting plate 61. The eighth driving member 617 is located on the side of the tenth slide rail 613 opposite to the eleventh slide rail 614 in the second direction Y, and the ninth driving member 618 is located on the side of the eleventh slide rail 614 opposite to the tenth slide rail 613 in the second direction Y.

[0102] To achieve vertical Z-axis movement of the support block 653, such as Figure 17 As shown, a connecting shaft 654 is connected to the bottom of the bearing block 653, and a fifth driving member 644 is connected to the bottom of the connecting shaft 654, which is used to drive the connecting shaft 654 to move the bearing block 653 in the vertical direction Z.

[0103] Preferably, the axes of the connecting shaft 654 and the first rotating shaft 632 coincide, the diameter of the connecting shaft 654 is smaller than the diameter of the first rotating shaft 632, and the connecting shaft 654 passes through the first rotating shaft 632. The diameter of the first rotating shaft 632 is smaller than the diameter of the second rotating shaft 622, and the first rotating shaft 632 passes through the second rotating shaft 622. This design can greatly reduce the volume of the mechanism and make full use of space.

[0104] like Figure 16 and Figure 17 As shown, the cable management assembly 6 also includes a fixedly mounted fourth mounting plate 62, which is located below the third mounting plate 61. A second rotating shaft 622 is rotatably connected to the fourth mounting plate 62. A tenth driving member 623 is connected to the fourth mounting plate 62. The driving end of the tenth driving member 623 is connected to the second rotating shaft 622 and is used to drive the second rotating shaft 622 to rotate the fourth clamping member 621.

[0105] Specifically, the cable management assembly 6 also includes a fixedly mounted fifth mounting plate 63, which is located below the fourth mounting plate 62. A first rotating shaft 632 is rotatably connected to the fifth mounting plate 63, and an eleventh driving member 635 is connected to the fifth mounting plate 63. The driving end of the eleventh driving member 635 is connected to the first rotating shaft 632 and is used to drive the first rotating shaft 632 to rotate the third clamping member 631.

[0106] Furthermore, the cable management assembly 6 also includes a fixedly mounted sixth mounting plate 64, located below the fifth mounting plate 63. A support column 641 is fixedly connected between the fourth mounting plate 62 and the sixth mounting plate 64; a first support base 642 connects the fourth mounting plate 62 and the fifth mounting plate 63; and a second support base 643 connects the fifth mounting plate 63 and the sixth mounting plate 64. The support column 641, the first support base 642, and the second support base 643 enable mutual fixation between the mounting plates. The fifth driving component 644 is connected to the bottom surface of the sixth mounting plate 64, resulting in a reasonable layout and efficient use of space.
