Description

Technical Field

[0001] This invention relates to the technical field of automated equipment, and more particularly to a flexible, replaceable, fully automatic coil winding device. Background Technology

[0002] Winding machines are key equipment for winding wire materials onto specific workpieces, and are particularly commonly used in processing scenarios such as winding inductor coils with enameled copper wire. In the production processes of various electrical products, winding is a core process; the manufacturing of transformers, inductors, and various coils all heavily rely on winding equipment, making it an indispensable basic piece of equipment on automated production lines.

[0003] However, most commonly available round wire winding machines, flat wire winding machines, and single-axis, double-axis, and multi-axis winding machines suffer from limited functionality and versatility. They can mostly only process coils of fixed types and sizes, exhibiting poor adaptability across specifications and types. While some machines can process coils of the same type but different sizes by changing components such as the winding die, the overall adjustment process is cumbersome and lacks flexibility, making it difficult to meet the needs of rapid production switching for multiple product categories and specifications.

[0004] Meanwhile, traditional equipment often uses simple ejection structures such as spring-loaded ejectors to detach the coil from the winding die. Manual handling suffers from low efficiency, poor positioning accuracy, and high labor intensity, making it difficult to meet the requirements of continuous, high-cycle production and only suitable for small-batch, customized scenarios. Furthermore, when using simple ejection mechanisms, the coil's detachment trajectory is easily affected by factors such as the direction of the thrust, friction, and gravity, making precise control of the landing point difficult. This often results in deviations, skewness, or drops, hindering stable integration with subsequent processes and making fully automated production difficult. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please refer to Figures 1-15This invention provides a flexible, replaceable, fully automatic coil winding device 100. The coil winding device 100 includes a worktable 110, a wire feeding unit 120, a winding unit 130, a material unloading unit 150, and a control unit (not shown in the figure). The wire feeding unit 120 is non-contact with the worktable 110. The winding unit 130 is mounted on the worktable 110 and includes a fixing frame 131, a winding module 132, and a drive module 133. The winding module 132 includes a clamping assembly 1321 and a winding assembly 1322. The fixing frame 131 is mounted on the worktable 110, the drive module 133 is mounted on the fixing frame 131, the winding assembly 1322 is mounted on the drive module 133, and the clamping assembly 1321 is mounted on the winding assembly 1322. The material unloading unit 150 is mounted on the worktable 110. The control unit is electrically connected to the wire feeding unit 120, the winding unit 130, and the unloading unit 150, respectively. The control unit is configured to: control the wire feeding unit 120 to transport the workpiece to be processed to the winding position of the winding unit 130, control the winding module 132 to move to the winding position, and have the winding assembly 1322 process the workpiece into a coil 200; then control the clamping assembly 1321 to clamp the coil 200 and control it to move to the unloading unit 150.

[0024] The coil winding device 100 in this embodiment, on the one hand, through the positional arrangement of the wire feeding unit 120, winding unit 130, storage unit 140, and unloading unit 150, and the fact that the winding unit 130, storage unit 140, and unloading unit 150 can all be detachably installed on the worktable 110, and the fixing frame 131 is characterized as being able to expand along the Y-axis direction, can thus realize the automated production of products of different types, quantities, and sizes. On the other hand, firstly, the coil 200 is wound by the winding assembly 1322, then the coil 200 is clamped by the clamping assembly 1321 and moved to the fixture in the storage unit 140, and then the fixture full of coil 200 is moved to the unloading unit 150, thereby realizing the fully automated production of coil 200.

[0025] The coil winding device 100 in this embodiment, through innovative design of core technical features, specifically addresses the pain points of existing winding machines such as poor flexibility, low automation, complex model changeover, and insufficient precision, bringing multi-dimensional core benefits: Firstly, the flexible production capacity is significantly enhanced, adapting to the needs of multiple varieties and small-batch production. Based on the design of the detachable and installable winding unit 130, storage unit 140, and unloading unit 150, and the universal installation standard of the worktable 110, rapid type and number of axis changes can be achieved across different types without modifying the main structure of the equipment. This helps solve the problems of existing winding machines having limited functionality and difficulty in adapting to different types. The fixed frame 131 can be extended along the Y-axis to assemble 1-3 winding modules 132, allowing for the splicing of multiple machines to achieve 4-axis or higher production. This not only adapts to small-batch, multi-specification products but also meets the needs of large-scale mass production through module expansion, enabling flexible batch adjustments.

[0026] Secondly, the fully automated closed-loop process, through the clamping component 1321 and multi-axis drive collaboration, enables unmanned operation of the coil 200 from winding and forming, precise transfer, jig storage to unloading, completely replacing traditional manual handling and semi-automatic loading and unloading. This addresses the pain points of existing winding machines, such as high reliance on manual labor and low efficiency. Traditional winding machines use a simple ejection mechanism to eject the coil 200. The coil 200's departure from the trajectory is easily affected by factors such as the direction of the thrust, friction, and gravity, making precise control of the landing point difficult and hindering fully automated production. This solution, however, uses a clamping component 1321 located beside the winding component 1322. After the coil 200 is wound, the clamping component 1321 clamps one of the coil 200's pins, facilitating the transport and precise placement of the coil 200, thus promoting automated production.

[0027] Thirdly, to improve the machining accuracy of coil 200, the X-axis drive assembly 1331, Y-axis drive assembly 1332 and Z-axis drive assembly 1323 constitute a three-dimensional precision positioning system, which works in conjunction with the sensing assembly 1322E of winding assembly 1322. The shared use of X-axis drive assembly 1331 and Y-axis drive assembly 1332 can reduce the number of parts, while independent control of Z-axis drive assembly 1323 can ensure the machining accuracy of coil 200.

[0028] The control unit is also configured to wind the same coil 200 at a first speed in the initial segment, a second speed in the stable segment, and a third speed in the final segment, with the speed values ​​of the third speed, first speed, and second speed increasing sequentially. Specifically, based on the total number of turns required to complete the coil 200, the initial segment is defined as the first 10% of the total turns, the stable segment as the middle 80% of the total turns, and the final segment as the last 10% of the total turns. By using a segmented speed-variable winding method for the same coil 200, the forming quality of the coil 200 can be significantly improved. The principle is as follows: the initial segment is the initial stage of coil 200 forming, where the wire just begins to adhere to the winding die and has not yet formed a stable arrangement. If winding is done directly at high speed, the wire is easily affected by starting impact and sudden tension changes, resulting in problems such as warping, shifting, loosening, or skipping of the wire at the beginning. This solution employs a lower rotation speed in the initial winding stage, allowing the wire to gradually and steadily conform to the winding die. This ensures the first few turns are neatly aligned and precisely positioned, providing a stable foundation for subsequent winding and improving the forming accuracy of coil 200 from the outset. The stable stage, comprising 80% of the total turns, is the main winding phase of coil 200. At this point, the wire has formed a stable alignment. A higher rotation speed is used in this stage, which avoids disrupting the neat alignment of coil 200 and effectively shortens the overall winding time, thus improving equipment production efficiency. The final stage, the final forming stage of coil 200, is prone to defects such as springback, bulging, overlap, and uneven wire lengths when the high-speed winding stops due to elastic deformation and internal stress generated during the winding process. This solution uses the lowest rotation speed in the final stage, allowing the wire to complete the final winding under low stress and low impact, effectively releasing the internal stress of the wire, significantly reducing the elastic rebound amplitude, and avoiding bulging, deformation, and wire pressing of coil 200 at the end, so that the overall end face of coil 200 is flat, which is conducive to further improving the product qualification rate.

[0029] Please refer to Figure 1 and Figure 6The coil winding device 100 also includes a storage unit 140. The winding unit 130, storage unit 140, and unloading unit 150 are all detachably mounted on the worktable 110 to achieve automated production of products of different types, quantities, and sizes. The fixing frame 131 is characterized as being expandable along the Y-axis to assemble different numbers of winding modules 132. For example, the coil winding device 100 of this embodiment takes a biaxial flat wire winding machine as an example. If it is necessary to switch the flat wire winding machine to a round wire winding machine, it is only necessary to disassemble the corresponding module and then assemble the corresponding module. For example, the fixing frame 131 of this embodiment can assemble two winding modules 132. If it is necessary to increase or decrease the number of corresponding winding modules 132, the fixing frame 131 of a suitable size is replaced. For example, it is replaced with a fixing frame 131 that can assemble three winding modules 132, thus becoming a three-axis winding module 132. It should also be noted that each workbench 110 in this application can only assemble a maximum of three winding modules 132. To convert it into a four-axis, six-axis, or ten-axis winding machine, multiple winding machines are spliced ​​together. The flexible, interchangeable, fully automatic coil winding device 100 also includes splicing components 170. Two adjacent workbenches 110 are connected together via two splicing components 170, with the spliced ​​workbenches 110 extending along the Y-axis. The splicing components 170 connect adjacent workbenches 110 using screws or bolts. During expansion, a corresponding length of fixing bracket 131 needs to be replaced, and each newly added winding module 132 requires the simultaneous configuration of an independent pay-off module 122 and a Z-axis drive assembly 1323. The control unit automatically identifies the number of modules and assigns control parameters without additional programming. The winding module 132 has a built-in encoding chip. After installation, the control unit automatically reads the encoding information through an interface, identifies the number of modules, and assigns the corresponding drive channels and control parameters without manual intervention. When multiple winding machines are spliced ​​together, adjacent workbenches 110 are fixed by special splicing parts 170, and the control units of each device are connected by an Ethernet bus. The main control unit uniformly schedules the action sequence of each winding machine. After splicing, it supports single-machine independent operation or multiple machines working together. The control unit can set unified production parameters or differentiated production parameters to adapt to the production of different batches and multiple specifications of products.

[0030] The specific steps for switching from a flat wire winding machine to a round wire winding machine are as follows: The winding machine provided in this embodiment is a biaxial flat wire winding machine. When switching to a round wire winding machine, the parts that need to be replaced include: the wire feeding unit 120, the straightening unit 180, the wire feeding unit 190, the winding assembly 1322, and the cutting assembly 134. For the fixture, a fixture with the same external dimensions can be used, thus eliminating the need to replace the storage unit 140 and the unloading unit 150. The worktable 110, the X-axis drive assembly 1331, the Y-axis drive assembly 1332, the Z-axis drive assembly 1323, the storage unit 140, and the unloading unit 150 do not need to be replaced. The wire feeding unit 120 is replaced with a wire feeding module 122 adapted to round wire materials to ensure stable tension during round wire feeding. The roller assembly 182 of the straightening unit 180 is replaced or adjusted. The roller assembly 182 needs to be replaced with one that matches the diameter of the round wire, or the original roller spacing needs to be adjusted to ensure that when the round wire passes through the wire-passing hole 1811 of the straightening body 181, the bending deformation can be corrected by the rolling action of the roller assembly 182, ensuring the straightness of the round wire to meet the winding accuracy. Furthermore, the shape and size of the wire-passing hole 1811 must match the shape and size of the flat wire when using the flat wire winding machine, and must match the shape and size of the round wire when switching to the round wire winding unit 130. The wire-passing hole 1811 of the straightening body 181 needs to be replaced with a circular hole accessory that matches the diameter of the round wire. The wire feeding unit 190 needs to have its pressure block component 193 and drive parameters replaced. The smooth surface of the round wire makes the clamping structure of the original flat wire clamping block component 193 prone to slippage. It needs to be replaced with a clamping block component 193 featuring an arc-shaped clamping surface and anti-slip material. Simultaneously, the downward pressure of the second wire feeding drive component 192 should be adjusted to prevent excessive pressure from damaging the round wire or insufficient pressure from causing wire feeding deviation. Furthermore, the wire feeding unit 190 has a wire feeding hole for copper wire to pass through. When using a flat wire winding machine, the shape and size of the wire feeding hole should match the shape and size of the flat wire; when switching to the round wire winding unit 130, the shape and size of the wire feeding hole should match the shape and size of the round wire. The winding assembly 1322 requires replacement of the winding die head component 1322D and its matching transmission structure. Key components such as the upper die component 1322D1, lower die component 1322D2, and winding cylinder 1322D3 need to be replaced. The cutting assembly 134 requires replacement of the cutting component 1342 to adapt to round wire cutting. For the fixture, a fixture with the same external dimensions can be used, thus eliminating the need to replace the storage unit 140 and the unloading unit 150. Only the placement slot of the fixture needs to be replaced with a slot that adapts to the circular line. The external dimensions of the fixture remain compatible with the sliding slot 1411 and positioning structure of the storage unit 140; only the flat placement slot fixture that adapts to the flat line is replaced with a circular slot fixture that adapts to the circular line. If the original fixture is an adjustable universal type, only the position of the positioning component 1445 of the fixture pressing assembly 144 needs to be adjusted; there is no need to modify the core structure such as the storage body 141 and the drive assembly. After the final switch, Figure 1 The flat wire winding machine shown is switched to Figure 15 The circular wire winding machine shown. (As shown) Figure 15The circular wire winding machine shown has the same layout of the first mounting position 111, the second mounting position 112, the third mounting position 113, and the straightening mounting position 114 on its worktable 110. Each mounting position has the same connection method, which facilitates the switching of each module. For example, the circular wire winding unit 130 and the flat wire winding unit 130 have holes of the same size, which can be detachably connected by bolts, so that the flat wire winding unit 130 can be replaced with the circular wire winding unit 130.

[0031] The specific method for switching between 1-axis and 3-axis winding machines: The winding machine provided in this embodiment is a dual-axis flat wire winding machine. To switch to a 3-axis flat wire winding machine, the following parts need to be replaced: the wire feeding unit 120, the straightening unit 180, the wire feeding unit 190, and the mounting bracket 131 that can accommodate 3 winding modules 132. Specifically, the wire feeding unit 120 can be a single wire feeding unit 120 capable of simultaneously holding 3 copper wires, or it can consist of 3 separate wire feeding units 120 capable of independently holding 1 copper wire. Similarly, the straightening unit 180 can be a single straightening unit 180 capable of simultaneously straightening 3 copper wires, or it can consist of 3 separate straightening units 180 capable of independently straightening 1 copper wire. Likewise, the wire feeding unit 190 can be a single wire feeding unit 190 capable of simultaneously feeding 3 copper wires, or it can consist of 3 separate wire feeding units 190 capable of independently feeding 1 copper wire.

[0032] The specific method for switching after exceeding 4 axes is as follows: Two or more winding machines are spliced ​​along the Y-axis using splicing component 170. For example, to achieve 4 axes, two dual-axis winding machines can be spliced ​​together, or a single-axis winding machine and a three-axis winding machine can be spliced ​​together. For example, to achieve 6 axes, two three-axis winding machines can be spliced ​​together.

[0033] The specific method for switching between winding machines with different sized coils 200: The winding machine provided in this embodiment is a biaxial flat wire winding machine. Switching to a biaxial flat wire winding machine with coils 200 of different sizes requires replacing the following parts: the straightening unit 180 and the winding assembly 1322. For the straightening unit 180, the entire straightening unit 180 can be replaced, or the roller assembly 182 with a different diameter can be replaced to create different gaps between the rollers, or the gaps between the rollers can be adjusted directly. For the winding assembly 1322, the entire winding assembly 1322 can be replaced, or only the winding die head component 1322D can be replaced. For the fixture, a fixture with the same external dimensions can be used, thus eliminating the need to replace the storage unit 140 and the unloading unit 150.

[0034] The worktable 110 includes a first mounting position 111, a second mounting position 112, and a third mounting position 113 arranged sequentially along the X-axis. A winding unit 130 is located at the first mounting position 111, a storage unit 140 at the second mounting position 112, and a feeding unit 150 at the third mounting position 113. This layout facilitates the detachable installation of each working module, adopts a universal layout, and allows for switching between the number of round wires, flat wires, and shafts. In this embodiment, detachable installation specifically refers to the provision of universal threaded mounting holes on the worktable 110. For example, the first mounting position 111 may have universal threaded mounting holes adapted to the mounting brackets 131 for one, two, and three axes. Understandably, a universal threaded mounting hole is provided at the second mounting position 112 for mounting the storage unit 140 of a round wire winding machine or a flat wire winding machine, and a universal threaded mounting hole is provided at the third mounting position 113 for mounting the unloading unit 150 of a round wire winding machine or a flat wire winding machine. Furthermore, multiple positioning pins are arranged around the periphery of the first mounting position 111, the second mounting position 112, and the third mounting position 113 to position the winding unit 130, the storage unit 140, and the unloading unit 150, ensuring precise positioning of each module during installation and enabling rapid production use after module switching. Of course, in specific applications, the detachable mounting can also be configured using an electromagnet, with module switching achieved by controlling the on / off state of the electromagnet. For detachable installation, a combination of universal threaded mounting holes and locating pins is preferred. The worktable 110 has multiple universal threaded holes pre-set at the corresponding mounting positions, and the bottom of the module is equipped with matching screw holes and locating pin holes. During installation, the locating pins are used to accurately align the modules before tightening the bolts. For scenarios requiring high-frequency model changes, electromagnet adsorption installation can be used to ensure quick disassembly of each working module.

[0035] Please refer to Figure 1 and Figure 6The wire feeding unit 120, winding unit 130, storage unit 140, and unloading unit 150 are arranged sequentially along the X-axis. This linear layout along the X-axis creates a continuous flow line for wire feeding, winding, storage, and unloading. The workpiece to be processed is conveyed unidirectionally along the X-axis. After processing, the coil 200 is directly transferred laterally to the storage unit 140 via the clamping assembly 1321. The full-load fixture then moves the coil 200 to the unloading unit 150 along the X-axis, eliminating the need for complex turning or cross-directional handling. This design adapts to the flow requirements of different types of coils 200, such as round and flat wires, avoiding interference during type changes due to a dispersed layout. Each mounting position clearly defines its functional boundaries. The first mounting position 111 is adapted to an expandable winding module 132, while the second and third mounting positions 112 and 113 are adapted to a universal fixture conveying structure. When producing different types of products, only the corresponding module needs to be replaced, without adjusting the overall layout, reducing the difficulty of cross-type type changes. The X-axis linear layout provides ample space for the fixed frame 131 to expand the winding module 132 along the Y-axis. After expansion, multiple winding modules 132 can still be precisely connected to the storage and unloading unit 150 along the X-axis without changing the core process flow. This is suitable for small-batch, multi-specification production, and can also meet the needs of large-scale production through module expansion, achieving flexible batch adjustment.

[0036] Please refer to Figure 7 , Figure 8 and Figure 9The storage unit 140 includes a storage body 141, a first storage drive component 142, a second storage drive component 143, and a fixture pressing component 144. The fixture pressing component 144 is connected to the storage body 141. The storage body 141 includes a sliding groove 1411, a first outlet groove 1412, and a temporary storage area 1413. The first storage drive component 142 is used to move the fixture along the Y-axis direction through the sliding groove 1411, and the second storage drive component 143 is used to move the fixture along the X-axis direction through the first outlet groove 1412 to the unloading unit 150. For example, the storage body 141 is used to transport the fixture. After the coil 200 is wound, it is placed in the fixture, and then the fixture and the coil 200 are moved to the unloading unit 150. It is understood that the fixture moves along the sliding groove 1411. The first storage drive assembly 142 includes a Y-axis transverse drive 1421, a transverse slider 1422, a transverse slide rail 1423, a Z-axis positioning cylinder 1424, and a positioning column 1425. The Y-axis transverse drive 1421 is mounted on the lower side of the storage body 141 and is connected to the transverse slider 1422. The transverse slider 1422 is slidably mounted on the transverse slide rail 1423. The Z-axis positioning cylinder 1424 is mounted on the transverse slider 1422 and the positioning column 1425 is connected to the Z-axis positioning cylinder 1424. The transverse slide rail 1423 is mounted on the lower side of the storage body 141. The storage body 141 has a clearance groove 1414, and the positioning column 1425 can extend to the upper side of the storage body 141 through the clearance groove 1414. The temporary storage area 1413 is used to place multiple fixtures, and the bottom of the temporary storage area 1413 has a slot for one fixture to pass through. The Y-axis transverse drive 1421 drives the transverse slider 1422 to move to a predetermined position along the Y-axis direction. Then, the Z-axis positioning cylinder 1424 drives the positioning column 1425 to rise, so that the positioning column 1425 contacts the fixture. At this time, the Y-axis transverse drive 1421 pulls the fixture through the positioning column 1425, so that the fixture moves from the temporary storage area 1413 to the sliding groove 1411, realizing the movement of the fixture in the Y-axis direction. The sliding groove 1411 is set on the upper side of the storage body 141. The fixture pressing assembly 144 includes a pressing drive 1441, a pressing slider 1442, a pressing slide rail 1443, a pressing plate 1444, a positioning component 1445, a pressing column 1446, and a first spring 1447. The pressing drive 1441 and the pressing slide rail 1443 are both installed on the storage body 141. The pressing slider 1442 is slidably disposed on the pressing slide rail 1443. The pressing plate 1444 is installed on the pressing slider 1442. The pressing column 1446 is slidably installed on the pressing plate 1444. The first spring 1447 abuts against the pressing column 1446 and the pressing plate 1444. The positioning component 1445 is installed on the pressing plate 1444.When the fixture pressing assembly 144 is in use, before moving the coil 200 onto the fixture, the pressing drive 1441 drives the pressing plate 1444 to descend. The pressing plate 1444 drives the positioning component 1445 and the pressing column 1446 to descend together. At this time, the positioning component 1445 is inserted into the positioning hole of the fixture to position the fixture. After the pressing column 1446 descends, it abuts against the surface of the fixture and presses the fixture by the elastic force of the first spring 1447 to prevent the fixture from tilting up. This is conducive to the precise placement of the coil 200 into the placement slot of the fixture, thereby further realizing the automated production of the coil 200 by the winding machine of this application. The second storage drive assembly 143 includes an X-axis transverse drive 1431 and a pusher 1432. The X-axis transverse drive 1431 is connected to the pusher 1432. When the fixture filled with coils 200 is pushed to the position of the first outlet groove 1412, the X-axis transverse drive 1431 drives the pusher 1432 to move along the X-axis direction, thereby pushing the fixture through the first outlet groove 1412 into the unloading unit 150.

[0037] Please refer to Figure 3 , Figure 4 and Figure 5 The clamping assembly 1321 includes a clamping telescopic cylinder 1321A, a clamping cylinder 1321B, and a clamping component 1321C. The clamping telescopic cylinder 1321A is mounted on the winding assembly 1322, the clamping cylinder 1321B is mounted on the clamping telescopic cylinder 1321A, and the clamping component 1321C is mounted on the clamping cylinder 1321B. Exemplarily, the clamping telescopic cylinder 1321A drives the clamping component 1321C to move along the Z-axis. Two clamping components 1321C are provided, each connected to one end of the clamping cylinder 1321B. The clamping cylinder 1321B can drive the two clamping components 1321C to move closer together or further apart. It should be noted that the clamping component 1321C has a rounded rectangular slot for manually adjusting the distance between the two clamping components 1321C. The end of the clamping component 1321C has a protrusion. When clamping the coil 200, the protrusion is used to hook the coil 200 to prevent it from falling off. The clamping process is as follows: after the coil 200 is wound, the clamping telescopic cylinder 1321A drives the clamping cylinder 1321B and the clamping component 1321C to descend. Then, the clamping cylinder 1321B drives the clamping component 1321C to close and clamp one end of the coil 200.

[0038] Please refer to Figure 3 , Figure 4 and Figure 5The winding assembly 1322 includes a winding telescopic component 1322A, a rotating central column 1322B, a winding rotation component 1322C, a winding die component 1322D, and a sensing component 1322E. The winding die component 1322D is mounted on the rotating central column 1322B, and the rotating central column 1322B is mounted on the winding telescopic component 1322A to drive the winding die component 1322D to move up and down. The winding rotation component 1322C is connected to the rotating central column 1322B to drive the winding die component 1322D to rotate. The sensing component 1322E is used to detect the position of the winding die component 1322D. Exemplarily, the winding telescopic component 1322A is used to drive the rotating central column 1322B to move along the Z-axis, and the winding rotation component 1322C is used to drive the rotating central column 1322B to rotate. The sensing assembly 1322E includes a second sensor 1322E1 and a second sensing plate 1322E2. The second sensing plate 1322E2 is disposed on the rotating central column 1322B, and the second sensor 1322E1 is mounted on the winding frame 1322F. The second sensing plate 1322E2 and the second sensor 1322E1 cooperate to confirm the origin of the rotating central column 1322B and to rotate the rotating central column 1322B back to the origin position.

[0039] Please refer to Figure 3 , Figure 4 and Figure 5 The wire assembly includes a winding frame 1322F, a winding die head component 1322D including an upper die component 1322D1, a lower die component 1322D2, a winding column 1322D3, a first pin 1322D4, and a second pin 1322D5, a winding rotation component 1322C including a winding rotation motor 1322C1 and a transmission component 1322C2, a rotating central column 1322B slidably disposed on the winding frame 1322F, the winding column 1322D3 and the first pin 1322D4 are both connected to the upper die component 1322D1, the second pin 1322D5 is connected to the lower die component 1322D2, the upper die component 1322D1 forms an upper inclined surface 13201, the lower die component 1322D2 forms a lower inclined surface 13202 and a winding groove 13203 that cooperates with the winding column 1322D3.

[0040] Please refer to Figure 3 , Figure 4 and Figure 5The telescopic component includes a winding telescopic cylinder 1322A1, a connecting frame 1322A2, and an elastic element 1322A3. The winding telescopic cylinder 1322A1 and the winding rotary motor 1322C1 are both installed on the winding frame body 1322F. The winding telescopic cylinder 1322A1 and the rotating central column 1322B are connected through the connecting frame 1322A2. The elastic element 1322A3 abuts between the connecting frame 1322A2 and the rotating central column 1322B. For example, the elastic element 1322A3 is a compression spring. After the coil 200 is processed, the clamping assembly 1321, together with the winding cylinder 1322D3, moves the processed coil 200 above the fixture. The clamping assembly 1321 and the winding cylinder 1322D3 together drive the coil 200 down. After the winding cylinder 1322D3 contacts the fixture, the elastic element 1322A3 begins to act as a buffer. When the elastic element 1322A3 is compressed to a certain extent, the winding telescopic cylinder 1322A1 drives the winding cylinder 1322D3 to rise, causing the winding cylinder 1322D3 to be pulled out of the coil 200. The specific timing of the activation of the winding telescopic cylinder 1322A1 is set according to the stroke parameters of the Z-axis drive assembly 1323. The lower die component 1322D2 is mounted on the storage unit 140. The rotating central column 1322B can slide along the Z-axis. Understandably, a linear bearing is provided between the rotating central column 1322B and the winding frame 1322F to reduce the frictional force of the rotating central column 1322B sliding along the Z-axis. The transmission component 1322C2 is a belt drive mechanism. Specifically, the transmission component 1322C2 includes a transmission belt, a driving pulley, and a driven pulley. The driving pulley is connected to the winding rotary motor 1322C1, and the driven pulley is mounted on the rotating central column 1322B. The winding rotary motor 1322C1 drives the driving pulley to rotate, and the driving pulley drives the driven pulley and the rotating central column 1322B to rotate via the transmission belt. Both the upper inclined surface 13201 and the lower inclined surface 13202 are spiral surfaces. When winding the coil 200, the winding assembly 1322 descends to insert the winding column 1322D3 into the winding groove 13203. Finally, the workpiece to be processed is transported between the second pin 1322D5 and the winding column 1322D3. Subsequently, the winding rotary motor 1322C1 drives the rotating central column 1322B and the upper mold component 1322D1 to rotate. The upper mold component 1322D1 and the lower mold component 1322D2 cooperate to wind the coil 200. It should be noted that during the winding process, the upper mold component 1322D1 rotates and rises at the same time. The upper inclined surface 13201 and the lower inclined surface 13202 together form a groove to accommodate the copper wire.The ends of both the first pin 1322D4 and the second pin 1322D5 are semi-cylindrical. At the beginning of winding, the two semi-cylindrical ends of the first pin 1322D4 and the second pin 1322D5 merge together to avoid interference between them. After the first turn is completed, the first pin 1322D4 and the second pin 1322D5 have a height difference, preventing further interference. Understandably, the first pin 1322D4 and the second pin 1322D5 are used to block the copper wire during winding.

[0041] Please refer to Figure 8 The winding unit 130 also includes a cutting assembly 134 and a correction assembly 135. The cutting assembly 134 includes a cutting drive 1341 and a cutting component 1342. The cutting drive 1341 drives the cutting component 1342 to move along the Z-axis. The correction assembly 135 includes a correction drive 1351 and a correction component 1352. The correction drive 1351 drives the correction component 1352 to move along the Y-axis. For example, because the copper wire will spring back, a certain preset angle needs to be wound during the winding of the coil 200. After winding, the correction drive 1351 drives the correction component 1352 to move and correct the coil 200, ensuring that the two ends of the coil 200 remain parallel. It should be noted that the copper wire is cut by the cutting assembly 134 before correction. After the winding assembly 1322 completes the winding of the preset number of turns, the operation process is as follows: the winding rotary motor 1322C1 stops, the cutting drive 1341 drives the cutting component 1342 to descend, cuts the copper wire, the cutting component 1342 resets, the correction drive 1351 drives the correction component 1352 to move along the Y-axis, the correction coil 200 is corrected, the correction component 1352 resets, and the clamping assembly 1321 starts clamping.

[0042] Please refer to Figure 11 , Figure 12 and Figure 13The wire feeding unit 120 includes a wire feeding frame 121 and a wire feeding module 122. The wire feeding module 122 includes a wire feeding drive 1221, a first shaft 1222, a second shaft 1223, a third shaft assembly 1224, and a fourth shaft 1225, all mounted on the wire feeding frame 121. The third shaft assembly 1224 includes a third shaft 1224A, a shaft arm 1224B, a rotating shaft 1224C, a tension spring 1224D, and a first sensor 12. 24E and the first sensing element 1224F are rotatably mounted on the pay-off frame 121 via a rotating shaft 1224C connected to a shaft arm 1224B. A third shaft 1224A is connected to the shaft arm 1224B. A tension spring 1224D is connected between the shaft arm 1224B and the pay-off frame 121. The first sensing element 1224F is mounted on the rotating shaft 1224C and works in conjunction with the first sensor 1224E. Exemplarily, it should be noted that one pay-off module 122 corresponds to one winding module 132. In this embodiment, the winding machine has two shafts, correspondingly providing two pay-off modules 122. A copper coil 200 is placed on the first shaft 1222, and the extended copper wire passes sequentially through the upper end of the second shaft 1223, the lower end of the third shaft 1224A, and the upper end of the fourth shaft 1225. When the wire feeding unit 190 feeds copper wire in the X-axis direction, the copper wire pulls the third shaft 1224A, causing the third shaft 1224A to move upward. At this time, the tension spring 1224D is in the tensioned state until the third shaft 1224A and the shaft arm 1224B reach the desired position. Figure 12 At the position indicated by the dotted line, the first sensing element 1224F triggers the first sensor 1224E, and the wire feeding drive 1221 drives the first shaft 1222 to rotate, causing the copper coil 200 to feed the wire forward. At this time, the shaft arm 1224B and the third shaft 1224A swing downward under the action of the tension spring 1224D, and the first sensing element 1224F disengages from the first sensor 1224E again.

[0043] Please refer to Figure 11 , Figure 12 and Figure 13The drive module 133 is used to drive the winding module 132 to move along the X-axis and Y-axis directions. The winding module 132 also includes a Z-axis drive assembly 1323, which is mounted on the Y-axis drive assembly 1332. The winding assembly 1322 is mounted on the Z-axis drive assembly 1323. A clamping assembly 1321 is disposed between the Z-axis drive assembly 1323 and the winding assembly 1322. One X-axis drive assembly 1331 and one Y-axis drive assembly 1332 are provided. The number of Z-axis drive assemblies 1323 is the same as the number of winding assemblies 1322, and each Z-axis drive assembly 1323 is independently controlled. For example, the drive module 133 includes an X-axis drive assembly 1331 and a Y-axis drive assembly 1332. The X-axis drive assembly 1331 is connected to the fixing frame 131, and the Y-axis drive assembly 1332 is connected to the X-axis drive assembly 1331. The X-axis drive assembly 1331, Y-axis drive assembly 1332, and Z-axis drive assembly 1323 are all ball screw drive structures. The winding frame 1322F of the winding assembly 1322 is mounted on the Z-axis drive assembly 1323, and the clamping telescopic cylinder 1321A is mounted on the winding frame 1322F. One X-axis drive assembly 1331 and one Y-axis drive assembly 1332 are provided, which can drive all winding modules 132 to move synchronously along the X / Y axes, avoiding action conflicts between multiple X / Y axis drives. Simultaneously, the number of Z-axis drive assemblies 1323 is the same as that of the winding assemblies 1322, and they are independently controlled, allowing multiple winding modules 132 to simultaneously perform winding, picking, and unloading actions. Sharing the X / Y axis drive assembly 1332 reduces the number of core drive components in the equipment, lowering the complexity of the mechanical structure and the probability of failure; the independent Z-axis drive only requires precise control of the lifting action of a single winding module 132. For the winding of coil 200, the control accuracy in the Z-axis direction is paramount. While the X and Y axes share a common axis, the Z-axis is controlled independently. This reduces structural complexity while ensuring accuracy in the Z-axis direction. The clamping assembly 1321 and different Z-axis drive assemblies 1323 are independently controlled, allowing for customized lifting stroke and speed parameters to be set according to the operational needs of different winding assemblies 1322. Even when the same equipment simultaneously produces multiple specifications of coil 200, independent adjustment of the Z-axis ensures the processing accuracy of each coil 200 without requiring additional adjustments to the overall X / Y axis position, thus improving adaptability for differentiated production.

[0044] Please refer to Figure 14The coil winding device 100 further includes a straightening unit 180 and a wire feeding unit 190. The straightening unit 180, the wire feeding unit 190, and the winding unit 130 are arranged sequentially along the X-axis direction. The straightening unit 180 is used to straighten the workpiece to be processed; the wire feeding unit 190 is used to drive the workpiece to be processed to move. For example, the straightening unit 180 includes a straightening body 181 and a roller assembly 182 disposed on the straightening body 181. The straightening body 181 forms a wire-passing hole 1811 for the workpiece to be processed to pass through. The wire feeding unit 190 includes a first wire feeding drive 191, a second wire feeding drive 192, and a pressure block component 193. The first wire feeding drive 191 is used to drive the second wire feeding drive 192 to move along the X-axis direction, and the second wire feeding drive 192 is used to drive the pressure block component 193 to move along the Z-axis direction. Two wire-passing holes 1811 are provided, and the roller assembly 182 is located between the two wire-passing holes 1811. The copper wire passes through the wire-passing hole 1811, the roller assembly 182, and the wire-passing hole 1811 in sequence to straighten the copper wire for subsequent winding of the coil 200. When wire feeding is required, the second wire feeding drive 192 first drives the pressure block component 193 to descend and press and fix the copper wire. Then, the first wire feeding drive 191 drives the second wire feeding drive 192 and the clamped copper wire to move along the X-axis direction, thereby realizing the feeding of the copper wire. The winding machine in this embodiment is a dual-axis flat wire winding machine. It can be understood that the straightening unit 180 in this embodiment can straighten two copper wires at the same time, and the wire feeding unit 190 can feed two copper wires at the same time. That is, there are two sets of roller assembly 182 and wire-passing holes 1811, and two sets of first wire feeding drive 191, second wire feeding drive 192, and pressure block component 193. The workbench 110 also includes a straightening mounting position 114, and the straightening unit 180 is mounted on the straightening mounting position 114. The straightening mounting position 114, the first mounting position 111, the second mounting position 112 and the third mounting position 113 are arranged sequentially along the X-axis direction.

[0045] Please refer to Figure 7 , Figure 8 and Figure 9The unloading unit 150 includes a first conveying component 151 and a second conveying component 152, with the second conveying component 152 located directly below the first conveying component 151. The storage unit 140 also includes a fixture lifting component 145, a fixture transfer component 146, and a fixture pushing component 147. The second conveying component 152 is provided with a second outlet groove 1521. The fixture loading process includes: driving the fixture pushing component 147 to push the fixture located on the second conveying component 152 onto the fixture lifting component 145 through the second outlet groove 1521; then driving the fixture lifting component 145 to rise; and then transferring the fixture on the fixture lifting component 145 to the temporary storage area 1413 through the fixture transfer component 146. Exemplarily, both the first conveying component 151 and the second conveying component 152 are belt conveying mechanisms, and the conveying directions of the first conveying component 151 and the second conveying component 152 are opposite. The fixture pushing assembly 147 drives the fixture to move along the X-axis, the fixture lifting assembly 145 drives the fixture to move along the Z-axis, and the fixture transfer assembly 146 drives the fixture to move along the Y-axis. The fixture pushing assembly 147 includes a pushing drive 1471 and a pushing component 1472, with the push drive 1471 connected to the pushing component 1472. The fixture lifting assembly 145 includes a lifting drive 1451 and a lifting component 1452, with the lifting drive 1451 connected to the lifting component 1452, and the lifting drive 1451 drives the lifting component 1452 to move along the Z-axis. The fixture transfer assembly 146 includes a support body 1461, a Y-axis transfer drive 1462, a Z-axis transfer drive 1463, a clamping drive 1464, and a clamping component 1465. The support body 1461 is mounted on the worktable 110. The Y-axis transfer drive 1462 is mounted on the support body 1461. The Z-axis transfer drive 1463 is connected to the Y-axis transfer drive 1462 and to the clamping drive 1464. The clamping drive 1464 is connected to the clamping component 1465. It is understood that the clamping drive 1464 is a cylinder, and there are two clamping components 1465. The clamping drive 1464 drives the two clamping components 1465 to open or close, thereby clamping the fixture. Y-axis transfer drive 1462 is used to move clamping component 1465 along the Y-axis direction, Z-axis transfer drive 1463 is used to move clamping component 1465 along the Z-axis direction, and clamping drive 1464 is used to drive clamping component 1465 to move along the X-axis direction. Figure 7As shown, the jig circulation path includes: the second conveying component 152 conveys an empty jig; the jig pushing component 147 pushes it to the jig lifting component 145; the jig lifting component 145 rises to the height of the temporary storage area 1413; the jig transfer component 146 clamps the empty jig and moves it into the temporary storage area 1413; the empty jig is moved to the position of the jig pressing component 144 via the first storage drive component 142; the jig pressing component 144 is activated to position the jig; the wound coil 200 is placed on the jig until it is full; the jig pressing component 144 is released; the full jig moves to the position of the first outlet groove 1412; the second storage drive component 143 transfers it to the first conveying component 151; the first conveying component 151 outputs the full jig; and in subsequent processes, the empty jig is transferred to the second conveying component 152 to form a closed loop.

[0046] The working process of a winding machine: (1) Preliminary preparation: jig loading and equipment readiness The second conveying component 152 of the unloading unit 150 continuously conveys empty fixtures. The control unit drives the fixture pushing component 147 of the storage unit 140 to push the empty fixtures through the second outlet slot 1521 onto the fixture lifting component 145. Subsequently, the fixture lifting component 145 is raised, and the fixture transfer component 146 transfers the empty fixtures from the lifting component to the temporary storage area 1413 of the storage body 141, completing the pre-preparation of the fixtures. The control unit monitors the status of each unit in real time. The winding unit 130 configures the corresponding number of winding modules 132 according to production needs, and the Z-axis drive component returns to the initial position. The winding component 1322 completes the origin calibration of the rotating central column 1322B through the sensing component 1322E to ensure the accuracy of the reference for subsequent winding actions.

[0047] (2) 200 coils are automatically wound and formed. The wire feeding unit 120 starts operating, and the wire feeding drive 1221 drives the first shaft 1222 to rotate and release the wire. The wire passes through the second shaft 1223, the third shaft 1224A, and the fourth shaft 1225 in sequence to complete the guidance and tension adjustment. The third shaft assembly 1224 maintains the wire tension in real time through the elastic swing action of the tension spring 1224D and the shaft arm 1224B. When the tension exceeds the preset range, the first sensing plate 1224F and the first sensor 1224E cooperate to trigger a signal, and the control unit adjusts the wire feeding speed in real time to prevent the wire from slack or breakage. The wire enters the straightening unit 180, passes through the wire hole 1811 of the straightening body 181, and is straightened by the roller group 182 to eliminate bending deformation. The wire feeding unit 190 clamps the wire through the pressure block component 193, and the first wire feeding drive 191 drives the wire to be accurately fed to the winding station of the winding unit 130.

[0048] The control unit drives the X-axis drive assembly and the Y-axis drive assembly to move the winding module 132 to the winding position. Then, the Z-axis drive assembly drives the winding assembly 1322 to descend, so that the winding cylinder 1322D3 is inserted into the winding groove 13203 of the lower mold component 1322D2. The winding rotary motor 1322C1 drives the rotating central column 1322B and the upper mold component 1322D1 to rotate. In conjunction with the lifting and lowering action of the winding telescopic component 1322A, the wire is wound in an orderly manner along the upper inclined surface 13201 and the lower inclined surface 13202 to form a coil 200. After winding, the cutting component 134 automatically cuts the wire, and the correction component 135 then acts to correct the springback deformation of the coil 200, so that the wire ends of the coil 200 remain neat and parallel.

[0049] (3) Coil 200 transfer and unloading After the coil 200 is formed, the clamping assembly 1321 descends under the drive of the clamping telescopic cylinder 1321A and clamps and fixes the coil 200 by the clamping component 1321C. The control unit then drives the X-axis drive assembly and the Y-axis drive assembly to move the clamping assembly 1321 and the coil 200 together to the top of the empty fixture. The clamping assembly 1321 drives the coil 200 to descend slowly. After the winding cylinder 1322D3 contacts the fixture, the elastic element 1322A3 provides a buffering effect. After it is in place, the winding telescopic cylinder 1322A1 drives the winding cylinder 1322D3 to rise and be withdrawn. The clamping component 1321C is released, and the coil 200 falls smoothly into the designated slot of the fixture.

[0050] After the fixture is filled with coil 200, the first storage drive component 142 moves the fixture along the sliding groove 1411 to the first outlet groove 1412, and then the second storage drive component 143 pushes the full fixture to the first conveying component 151 of the unloading unit 150; the first conveying component 151 outputs the full fixture to the next process, and the empty fixture flows back to the second conveying component 152 to re-enter the loading cycle, realizing the closed-loop circulation of the fixture and continuous automated production.
