Description

Technical Field

[0001] This invention belongs to the field of transformer coil winding technology, specifically relating to an integrated production equipment for winding and forming 10kV complete transformer coils. Background Technology

[0002] In the production of 10kV complete transformers, coil winding is a crucial process, and its quality and efficiency directly affect the transformer's performance and production cycle.

[0003] Currently, during coil winding, the traditional method requires manually inserting interlayer spacers. Manually inserting spacers demands constant concentration from the operator, placing the spacers in a timely manner according to the winding progress. Even slight negligence can lead to inaccurate placement or uneven spacing of the spacers, affecting the electrical performance and overall quality of the coil. Furthermore, manual operation is relatively slow, severely limiting winding efficiency. Under the demands of large-scale production, this method not only consumes a significant amount of manpower and extends the production cycle but also increases production costs.

[0004] The current winding method, which relies on manually inserting interlayer spacers, is no longer sufficient to meet the requirements of efficient and high-quality production. Therefore, it is necessary to develop an integrated production equipment for 10kV transformer coil winding that can automatically place interlayer spacers during the coil winding process. This is of great significance for improving production efficiency and ensuring product quality. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated production equipment for winding and forming 10kV complete transformer coils, so as to realize the automatic insertion of interlayer spacers during coil winding.

[0006] To achieve the above objectives, embodiments of the present invention provide an integrated production equipment for winding and forming 10kV complete transformer coils, comprising: A cylindrical body for winding a coil, having several circumferentially arranged through holes; Interlayer spacers, which are used to separate adjacent coils; A feeding component is disposed inside the cylinder and is used to feed the interlayer pad through the through-hole. The feeding component has several circumferentially arranged feeding holes, which are oriented toward the through-hole.

[0007] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the feeding component includes: A feeding cylinder is disposed inside the cylinder and has the feeding holes, with one interlayer pad placed in each feeding hole; A first elastic element has one end disposed at the bottom of the feeding hole and the other end abutting against the interlayer pad, for pushing the interlayer pad to slide closer to the through hole.

[0008] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the feeding component further includes: A rotating stop is rotatably disposed on the outer wall of the feeding cylinder. It has a blocking state and a yielding state. When it is in the blocking state, the rotating stop can block the interlayer pad, preventing the interlayer pad from being pushed out of the feeding hole by the first elastic member. When it is in the yielding state, the rotating stop can release the interlayer pad, allowing the interlayer pad to be pushed into the through hole by the first elastic member.

[0009] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the interlayer pad has an annular retaining edge, the inner wall of the cylinder has a retaining groove, and the annular retaining edge is used to be engaged in the retaining groove.

[0010] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil. The interlayer spacer has a through hole at one end away from the annular retaining edge, and also includes a connecting rod for passing through the through hole of a row of interlayer spacers to connect the row of interlayer spacers.

[0011] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, which further includes a limiting component disposed outside the cylinder and used to limit the position of the interlayer pad being pushed by the first elastic member in the through-hole.

[0012] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the limiting component includes: A baffle is provided on the outer periphery of the cylinder and is arranged in a plurality of circles along the axial direction of the cylinder. Each baffle is used to block a row of interlayer pads and, after moving along the axial direction, sequentially cancels the blocking of the interlayer pads, so that the blocked interlayer pads can be lower than the coil to be wound.

[0013] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the limiting component further includes: An axially movable component is disposed above the cylinder body, moving axially along the cylinder body. A radially moving member is disposed on the axially moving member along the radial direction of the cylinder and is arranged in several circumferential circles. The baffle member is disposed on the radially moving member, so that it can be driven by the axially moving member to achieve axial movement and by the radially moving member to achieve radial movement.

[0014] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the radially moving member has a pushed inclined surface, and the limiting assembly further includes: The pusher has several circumferentially arranged pushing inclined surfaces, which slide against the pushed inclined surface. The pusher is slidably disposed on the axially moving member along the axial direction. After moving, it can push the radially moving member to move through the pushing inclined surface and the pushed inclined surface.

[0015] For example, at least one embodiment of this disclosure provides an integrated production equipment for winding and forming a 10kV complete transformer coil, wherein the radially moving member has a pushed inclined surface, and the limiting assembly further includes: The second elastic element has one end acting on the axial moving element and the other end acting on the radial moving element, and is used to provide a force for the radial moving element to move in the centrifugal direction.

[0016] The technical effects of the embodiments of the present invention are as follows: The feeding mechanism enables automatic feeding of interlayer spacers, eliminating the need for manual insertion and significantly reducing manual operation time. Whether for automatic or manual winding, operators only need to control the state of the rotating stop to quickly place the interlayer spacers, increasing coil winding speed, shortening the production cycle, and meeting the needs of large-scale production.

[0026] Please see Figures 1-5 The illustration shows an integrated production equipment for winding and forming a 10kV complete transformer coil according to an embodiment of the present invention, including a cylinder 100, interlayer spacers 200 and a feeding device 300. The cylinder 100 is used for winding the coil and has several circumferentially arranged through holes 110. The interlayer spacers 200 are used to separate adjacent coils. The feeding device 300 is disposed inside the cylinder 100 and is used to feed the interlayer spacers 200 through the through holes 110. The feeding device 300 has several circumferentially arranged feeding holes 310, which are directed toward the through holes 110.

[0027] The feeding component 300 includes a feeding cylinder 320, a first elastic element 330, and a rotating stop 340. The feeding cylinder 320 is disposed inside the cylinder body 100 and has feeding holes 310, in which an interlayer pad 200 is placed. One end of the first elastic element 330 is disposed at the bottom of the feeding hole 310, and the other end abuts against the interlayer pad 200, for pushing the interlayer pad 200 to slide closer to the through-hole 110. The rotating stop 340 is rotatably disposed on the outer wall of the feeding cylinder 320 and has a blocking state and a yielding state. In the blocking state, the rotating stop 340 can block the interlayer pad 200, preventing the interlayer pad 200 from being pushed out of the feeding hole 310 by the first elastic element 330. In the yielding state, the rotating stop 340 releases the interlayer pad 200, allowing the interlayer pad 200 to be pushed into the through-hole 110 by the first elastic element 330.

[0028] For example, the cylinder 100 needs to be made of high-strength insulating materials, such as epoxy resin or other high-performance insulating plastics, to meet electrical insulation requirements. Its shape is a hollow cylinder, with a diameter designed according to the specifications of the 10kV complete transformer coil, generally ranging from tens of centimeters to about one meter. Several concentric rings of through-holes 110 are distributed on the wall of the cylinder 100. These through-holes 110 are evenly spaced along the circumference of the cylinder 100 and penetrate the wall of the cylinder 100. The diameter of the holes is slightly larger than the thickness of the interlayer spacer 200 so that the interlayer spacer 200 can pass through smoothly. The number of through-holes 110 in each ring is determined according to the number of coil layers and design requirements. Typically, there are dozens of through-holes 110 in one ring. The through-holes 110 in different rings can be aligned in the axial direction or staggered according to a special coil structure design.

[0029] The cylinder 100 serves as the basic component for coil winding, providing a supporting structure for the coil winding. Through-holes 110 allow interlayer spacers 200 to pass through, thereby separating adjacent coils and ensuring the electrical performance and structural stability of the coil. During coil winding, the cylinder 100 must remain stable to ensure the uniformity and precision of the coil winding.

[0030] The interlayer spacer 200 can be made of a material with good insulation properties and a certain mechanical strength, such as insulating cardboard or special insulating composite materials. Its length is greater than the wall thickness of the cylinder 100, and its width is determined according to the coil wire diameter and interlayer spacing requirements. The surface of the interlayer spacer 200 should be flat and smooth to avoid damaging the coil during insertion.

[0031] The main function of the interlayer spacer 200 is to separate adjacent coil layers during the coil winding process, forming a certain insulation gap to prevent short circuits between coil layers and improve the electrical insulation performance of the coil. At the same time, the interlayer spacer 200 can also enhance the mechanical structural stability of the coil to a certain extent, enabling the coil to withstand the influence of electromagnetic forces and temperature changes during operation.

[0032] The feeding cylinder 320 is located inside the cylinder 100 and is coaxially arranged with the cylinder 100. The outer diameter of the feeding cylinder 320 is slightly smaller than the inner diameter of the cylinder 100 to ensure that the feeding cylinder 320 can be placed relatively stably inside the cylinder 100 without hindering the coil winding operation. Feeding holes 310 are provided on the wall surface of the feeding cylinder 320, corresponding to the through-holes 110 in the cylinder 100. The feeding holes 310 are also arranged in several concentric circles, and each concentric circle of feeding holes 310 corresponds one-to-one with the corresponding concentric circle of through-holes 110 in the cylinder 100 in the circumferential direction. The diameter of the feeding holes 310 is slightly larger than the width of the interlayer spacer 200, and the depth is slightly larger than the length of the interlayer spacer 200, ensuring that each feeding hole 310 can accommodate one interlayer spacer 200.

[0033] The feeding cylinder 320 serves as a storage and conveying carrier for the interlayer spacer 200. Its feeding hole 310 stores the interlayer spacer 200 and, through its correspondence with the through-hole 110 of the cylinder 100, guides the accurate delivery of the interlayer spacer 200, allowing it to smoothly pass through the through-hole 110 to reach the designated position. After the coil winding is completed, the feeding cylinder 320 needs to be removed from the cylinder 100. To ensure that the feeding hole 310 of the feeding cylinder 320 aligns with the through-hole 110 of the cylinder 100, positioning protrusions and positioning grooves can be provided to ensure alignment.

[0034] The first elastic element 330 is usually a spring, with one end fixed to the bottom of the feed hole 310 and the other end abutting against the interlayer pad 200 placed in the feed hole 310. It is necessary to ensure that the interlayer pad 200 can be smoothly pushed to slide into the through hole 110, but not to use excessive pushing force that would damage the interlayer pad 200 or cause inaccurate installation.

[0035] The first elastic element 330 provides the pushing force for the interlayer pad 200. When the rotating stop 340 is in the open state, the interlayer pad 200 is pushed out from the feeding hole 310 and passes through the through insertion hole 110 of the cylinder 100, realizing the automatic feeding function of the interlayer pad 200, reducing manual operation and improving production efficiency.

[0036] The rotating stop 340 is rotatably mounted on the outer wall of the feeding cylinder 320 and should be able to block the feeding hole 310 to prevent the interlayer pad 200 from being pushed out by the first elastic element 330 when it is not needed. The rotating stop 340 can be operated manually or automatically controlled by a drive device such as a motor or cylinder. In manual operation, an operating handle is usually provided on the rotating stop 340 for the operator to operate according to the winding progress; in automatic control, the drive device controls the rotation of the rotating stop 340 according to a preset program or signals fed back from sensors.

[0037] The rotating stop 340 controls the timing of the ejection of the interlayer spacer 200. In the blocking state, the rotating stop 340 blocks the feeding hole 310, preventing the interlayer spacer 200 from being ejected by the first elastic member 330, ensuring that the feeding system is in a stable state when the interlayer spacer 200 is not needed. In the open state, the rotating stop 340 removes the obstruction of the feeding hole 310, allowing the first elastic member 330 to push the interlayer spacer 200 into the through-hole 110, realizing the timely placement of the interlayer spacer 200 and ensuring the accuracy and orderliness of the spacer placement during coil winding.

[0038] During operation, fix the cylinder 100 in a suitable position on the winding equipment to ensure its stability. Place the feeding cylinder 320 inside the cylinder 100 and adjust their relative positions so that the feeding hole 310 accurately aligns with the through hole 110. Check the rotation flexibility of the rotating stop 340 and whether its material blocking and clearance functions are normal.

[0039] The interlayer spacers 200 are placed one by one into the feeding holes 310 of the feeding cylinder 320, so that the first elastic member 330 is in a compressed state, preparing for the ejection of the interlayer spacers 200. During the loading process, it is necessary to ensure that each feeding hole 310 is filled with an interlayer spacer 200, and that the interlayer spacers 200 are neatly placed in the feeding holes 310 to avoid tilting or jamming.

[0040] When winding the coil, start the winding equipment and begin winding the coil on the coil cylinder 100. The winding method can be automatic winding, in which the winding speed, number of turns and wire arrangement parameters are precisely controlled by the control system of the winding machine; or it can be manual winding, in which the operator manually winds the wire evenly around the cylinder 100.

[0041] When the winding reaches the position where the interlayer spacer 200 needs to be placed, the operation is performed according to the different operating methods. The rotating stop 340 is operated to the open state, and the first elastic member 330 immediately pushes out the interlayer spacer 200 in the feed hole 310. The interlayer spacer 200 passes through the through insertion hole 110 of the cylinder 100 and reaches the predetermined position between adjacent coils, thereby separating adjacent coils.

[0042] Once the coil winding is complete, stop the winding equipment. Inspect the wound coil to check if the interlayer spacers 200 are placed accurately and evenly, and whether the number of turns and wiring of the coil meet the design requirements. If any problems are found, make adjustments or rework them promptly.

[0043] The design of the feeder 300 enables automatic feeding of the interlayer spacer 200, eliminating the need for manual insertion of the spacer blocks and significantly reducing manual operation time. Whether it is automatic or manual winding, the operator only needs to control the state of the rotating stop 340 to quickly place the interlayer spacer 200, which improves the speed of coil winding, shortens the production cycle, and meets the needs of large-scale production.

[0044] The equipment is designed to allow for continuous coil winding and interlayer pad placement, avoiding the interruptions and waiting time that occur during manual pad placement, thus improving the equipment's working efficiency and further enhancing overall production efficiency.

[0045] Through the precise correspondence between the feeding cylinder 320, the feeding hole 310 and the through insertion hole 110 of the cylinder 100, and the synergistic effect of the first elastic element 330 and the rotating stop 340, the interlayer pad 200 can be accurately placed in the predetermined position between adjacent coils, avoiding the problem of inaccurate position or uneven spacing that may occur with manual placement, thereby ensuring the electrical performance and overall quality of the coil.

[0046] The precise placement of the 200mm interlayer spacer creates a uniform insulation gap, improving the stability of the coil's insulation performance. During transformer operation, it can better withstand electrical stress and temperature changes, reducing the risk of failures due to poor interlayer insulation, and improving product reliability and service life.

[0047] Automated interlayer pad feeding reduces reliance on manual labor, lowering labor costs. This advantage is even more pronounced in large-scale production, significantly reducing the number of operators and improving production efficiency. Because product quality is guaranteed, the number of defective coils due to improper pad placement is reduced, lowering the scrap rate and thus saving on raw material and production costs.

[0048] In some examples, the interlayer spacer 200 has an annular retaining edge 210, and the inner wall of the cylinder 100 has a retaining groove 120, the annular retaining edge 210 being used to engage within the retaining groove 120. The end of the interlayer spacer 200 away from the annular retaining edge 210 has a through hole 220, and also includes a connecting rod 400 for connecting a row of interlayer spacers 200 by passing through the through holes 220.

[0049] For example, the annular retaining edge 210 surrounds the outer periphery of the interlayer spacer 200, and is typically integrally formed with the interlayer spacer 200, using the same insulating material as the interlayer spacer 200. This ensures that the interlayer spacer 200 can smoothly pass through the through-hole 110 of the cylinder 100. The outer diameter of the annular retaining edge 210 is slightly larger than the diameter of the through-hole 110 so that it can be engaged with the retaining groove 120 on the inner wall of the cylinder 100.

[0050] The slots 120 are provided on the inner wall of the cylinder 100, corresponding to the annular retaining edge 210, and are evenly distributed along the circumferential direction of the inner wall of the cylinder 100, and are also corresponding in position to the through holes 110. The depth of the slots 120 is adapted to the thickness of the annular retaining edge 210, and the width is slightly larger than the width of the annular retaining edge 210 to ensure that the annular retaining edge 210 can be tightly engaged.

[0051] When the interlayer spacer 200 is pushed out by the feeder 300 and passes through the through-hole 110, the annular retaining edge 210 can be engaged in the retaining groove 120, thereby achieving stable fixation of the interlayer spacer 200 on the cylinder 100. This structural design effectively prevents the interlayer spacer 200 from shifting or falling off due to electromagnetic force, vibration and other factors during transformer operation, ensuring that the insulation distance between adjacent coils remains stable, thereby guaranteeing the electrical performance and overall stability of the coils.

[0052] The through hole 220 is located at the end of the interlayer spacer 200 away from the annular retaining edge 210. Its shape is typically circular, and its diameter is determined by the diameter of the connecting rod 400, generally slightly larger than the outer diameter of the connecting rod 400 to ensure smooth passage of the connecting rod 400. The axis of the through hole 220 is parallel to the length of the interlayer spacer 200 and located at the center of the interlayer spacer 200 to ensure uniform force distribution when the connecting rod 400 passes through.

[0053] The connecting rod 400 is also made of high-strength insulating material, such as a glass fiber reinforced plastic rod. Its diameter is designed according to the size of the through hole 220, and its length is determined by the number of rows of interlayer spacers 200 to be connected and the axial length of the cylinder 100. The surface of the connecting rod 400 should be smooth to reduce friction when passing through the through hole 220, and both ends can be designed with easy-to-operate shapes, such as threads or knobs, for easy installation and disassembly.

[0054] The connecting rod 400 connects the interlayer spacers 200 into a whole by passing through the through holes 220 of the row of interlayer spacers 200 in sequence. This not only further enhances the stability of the interlayer spacers 200, preventing individual interlayer spacers 200 from shaking or shifting, but also improves the overall mechanical strength of the coil to a certain extent. During transformer operation, the connecting rod 400 can better resist the effects of electromagnetic forces and vibrations on the interlayer spacers 200, ensuring the stability of the coil structure and guaranteeing the reliable operation of the transformer.

[0055] After all coils are wound, the first elastic element 330 pushes the interlayer spacer 200 to its limit position. The interlayer spacer 200 passes through the through-hole 110, and the annular retaining edge 210 engages with the retaining groove 120 on the inner wall of the cylinder 100, thus fixing the interlayer spacer 200. After the interlayer spacer 200 is in its final position, the connecting rod 400 is inserted into the through-hole 220 from one end to connect the row of interlayer spacers 200, thereby locking the interlayer spacers 200 and the coils.

[0056] The engagement structure of the annular retaining edge 210 and the retaining groove 120 provides reliable circumferential fixation for the interlayer spacer 200, effectively preventing the interlayer spacer 200 from shifting or falling off due to external forces such as electromagnetic force and vibration during transformer operation. This greatly improves the stability of the insulation distance between adjacent coils and ensures the electrical performance of the coils.

[0057] The connecting rod 400 connects a row of interlayer spacers 200, enhancing the axial stability of the interlayer spacers 200 and making the interlayer spacers 200 form an integral structure, which better resists the influence of various external forces and further improves the overall mechanical strength and stability of the coil.

[0058] Through the coordinated action of the annular retaining edge 210, the retaining groove 120, and the connecting rod 400, the coil can better adapt to various complex operating conditions during transformer operation, such as frequent load changes and vibration environments, ensuring stable operation under different working conditions and improving the adaptability and reliability of the product.

[0059] The structure, including the annular retaining edge 210, the retaining groove 120, and the connecting rod 400, makes the installation and fixing of the interlayer pad 200 more convenient and accurate. The automatic engagement of the annular retaining edge 210 and the retaining groove 120, as well as the quick connection of the connecting rod 400, reduces the amount of manual adjustment and fixing work, thereby improving production efficiency.

[0060] In some examples, a limiting component 500 is also included, disposed outside the cylinder 100, for limiting the position of the interlayer spacer 200 pushed by the first elastic member 330 in the through-hole 110. The limiting component 500 includes baffles 510, which are movably disposed along the axial direction of the cylinder 100 on the outer periphery of the cylinder 100, arranged in a plurality of circumferentially. Each baffle 510 is used to block a row of interlayer spacers 200 and, after moving along the axial direction, sequentially releases the blocking of the interlayer spacers 200, so that the blocked interlayer spacers 200 can be lower than the coil to be wound.

[0061] For example, the limiting component 500 can control the position of the interlayer spacer 200 pushed by the first elastic member 330 in the through-hole 110, ensuring that the interlayer spacer 200 is in the right position during the coil winding process, without affecting the coil winding and effectively separating adjacent coil layers, thereby improving the quality and efficiency of coil winding.

[0062] There are several baffle components 510, arranged at equal intervals along the circumference of the cylinder 100. Each baffle component 510 is usually a rectangular plate structure, and its length is determined according to the circumference of the cylinder 100 and actual needs. It can generally cover the arc length range of the cylinder 100 corresponding to a row of interlayer pads 200; it has a certain strength and rigidity, such as being made of metal or high-strength engineering plastics.

[0063] The baffle 510 is movably disposed on the outer periphery of the cylinder 100 along the axial direction of the cylinder 100. These moving structures must ensure that the baffle 510 can move smoothly and steadily along the axial direction, and that its moving distance can be controlled. During the winding of the coil, the initial position of the baffle 510 is to block a row of interlayer spacers 200, preventing them from protruding excessively from the through-hole 110 due to the thrust of the first elastic member 330, ensuring that the blocked interlayer spacers 200 are lower than the coil to be wound, and avoiding the interlayer spacers 200 from affecting the normal winding of the coil.

[0064] When the winding reaches the position where the interlayer spacer 200 needs to be placed, the drive device moves the baffle 510 axially, sequentially removing any obstruction to the interlayer spacer 200. At this time, the first elastic member 330 pushes the interlayer spacer 200 out, positioning it appropriately to separate adjacent coil layers. This precise control method ensures the accuracy and timeliness of the placement of the interlayer spacer 200, improving the quality and efficiency of coil winding.

[0065] During coil winding, the winding equipment is started to begin winding the coil on the coil cylinder 100. When a certain position is completed, the baffle 510 is moved axially along the cylinder 100 to remove the obstruction of the interlayer spacer 200 at that position. The first elastic member 330 immediately pushes the interlayer spacer 200 out of the feed hole 310. The interlayer spacer 200 passes through the through-hole 110 of the cylinder 100 and reaches the predetermined position between adjacent coils, thus separating the adjacent coils.

[0066] The limiting component 500 allows the interlayer spacer 200 to be precisely positioned during its ejection process via the baffle 510. The baffle 510 blocks the interlayer spacer 200 during winding, preventing it from extending prematurely and affecting coil winding. The baffle is released at the appropriate time, ensuring the interlayer spacer 200 accurately reaches the predetermined position between adjacent coils. This effectively improves the placement accuracy of the interlayer spacer 200 and guarantees the accuracy of the insulation distance between adjacent coils.

[0067] By adjusting the moving distance and speed of the baffle 510, the placement and timing of the interlayer spacer 200 can be adapted to the requirements of winding coils of different specifications. Whether winding thicker or thinner coil layers, or coils with different numbers of turns, the baffle 510 can be precisely controlled to ensure that the interlayer spacer 200 is pushed out at the most suitable position and time, thus improving the equipment's adaptability to various coil winding processes.

[0068] During the winding process, the baffle 510 ensures that the blocked interlayer spacer 200 is lower than the coil to be wound, effectively preventing the interlayer spacer 200 from interfering with the coil winding. This makes the coil winding process smoother, reduces problems such as abnormal wire winding and uneven coil arrangement caused by improper positioning of the interlayer spacer 200, and improves the efficiency and quality of coil winding.

[0069] Because the limiting component 500 can precisely control the placement of the interlayer spacer 200, it ensures the stability and consistency of the insulation distance between adjacent coils, thereby improving the electrical performance stability of the coils. This helps to improve the overall quality of the 10kV complete transformer, reduce product performance fluctuations caused by interlayer insulation problems, and improve product reliability and pass rate.

[0070] In some examples, the limiting component 500 further includes an axial moving member 520, a radial moving member 530, a pushing member 540, and a second elastic member 550. The axial moving member 520 is movably disposed above the cylinder 100 along the axial direction of the cylinder 100, and the radial moving member 530 is movably disposed on the axial moving member 520 along the radial direction of the cylinder 100 and is arranged in several circumferentially. The baffle member 510 is disposed on the radial moving member 530, so that it can be driven by the axial moving member 520 to achieve axial movement and by the radial moving member 530 to achieve radial movement.

[0071] The radial moving member 530 has a pushed inclined surface 531, and the pushing member 540 has several circumferentially arranged pushing inclined surfaces 541. The pushing inclined surfaces 541 slide against the pushed inclined surfaces 531. The pushing member 540 is axially slidably disposed on the axial moving member 520. After movement, it can push the radial moving member 530 to move through the pushing inclined surfaces 541 and the pushed inclined surfaces 531. The second elastic member 550 acts on the axial moving member 520 at one end and on the radial moving member 530 at the other end, and is used to provide a force for the radial moving member 530 to move in the centrifugal direction.

[0072] For example, the axial moving component 520 is elongated and typically made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure its stability and load-bearing capacity during movement. It is positioned above the cylinder 100 along its axial direction and connected to the support of the cylinder 100 via linear guide rails and sliders, ensuring smooth axial movement. The length of the axial moving component 520 is slightly greater than the axial length of the cylinder 100 to provide sufficient movement space for the radial moving component 530. The axial moving component 520 is equipped with structures, such as grooves or guide rails, that cooperate with the radial moving component 530 and the pushing component 540, ensuring precise connection and smooth movement between the components.

[0073] The axial moving component 520 is mainly responsible for driving the radial moving component 530 and the baffle component 510 to move along the axial direction of the cylinder 100. Through this axial movement, the position of the baffle component 510 in the axial direction can be precisely adjusted according to different positions of the coil winding, ensuring that the baffle component 510 can accurately limit and control the interlayer spacer 200 at different positions, and meet the requirements of different coil winding processes for the placement of the interlayer spacer 200 in the axial position.

[0074] Several radially moving parts 530 are arranged at equal intervals along the circumference of the axially moving parts 520. Each radially moving part 530 is block-shaped, with one end connected to the axially moving part 520 via a sliding structure, allowing it to move radially along a groove or guide rail on the axially moving part 520. A baffle 510 is provided at the other end of each radially moving part 530, fixed by bolts or integral molding. A pushed inclined surface 531 is provided on the side of the radially moving part 530 near the pushing member 540 to achieve force transmission.

[0075] The radial moving member 530 serves two purposes. First, it acts as a carrier for the baffle member 510, driving the baffle member 510 to move radially, thereby adjusting the radial distance between the baffle member 510 and the cylinder 100 to meet the requirements of gradually winding a thicker coil. Second, its pushed inclined surface 531 cooperates with the pushing inclined surface 541 of the pushing member 540, converting the axial force of the pushing member 540 into a radial force when the pushing member 540 moves, thus realizing the radial movement of the radial moving member 530 and the baffle member 510. Simultaneously, under the action of the second elastic member 550, the radial moving member 530 always tends to move in the centrifugal direction, ensuring that the baffle member 510 can maintain a suitable radial position when the pushing member 540 is not subjected to external force, effectively limiting the interlayer pad 200.

[0076] The pusher 540 has a ring-shaped structure and is slidably mounted on the axially moving member 520. It is also made of high-strength metal material. Several circumferentially arranged pushing inclined surfaces 541 are provided on the inner circumferential surface of the pusher 540. The pushing inclined surfaces 541 slide against the pushed inclined surface 531 of the radially moving member 530, and the angle of the pushing inclined surface 541 matches that of the pushed inclined surface 531. The pusher 540 is driven by a linear drive such as a cylinder or electric cylinder, enabling it to slide smoothly axially on the axially moving member 520.

[0077] The main function of the pusher 540 is to convert axial force into radial force through its axial movement, utilizing the sliding contact between the pushing inclined surface 541 and the pushed inclined surface 531 of the radial moving component 530, thereby driving the radial moving component 530 and the baffle component 510 to move radially. By controlling the moving distance and speed of the pusher 540, the radial distance between the baffle component 510 and the cylinder 100 can be precisely adjusted to meet the requirements of different coil winding processes for the radial position of the interlayer spacer 200, further improving the accuracy and adaptability of the placement of the interlayer spacer 200.

[0078] The second elastic element 550 is made of a material with good elastic properties, such as a spring or elastic rubber. One end of it is fixed to the axial moving element 520, and the other end is connected to the radial moving element 530. The spring constant is selected according to actual needs, ensuring that it can provide sufficient force for the radial moving element 530 to move in the centrifugal direction, while also ensuring that the spring can be appropriately compressed when the pushing element 540 pushes the radial moving element 530, so as not to affect the normal movement of the radial moving element 530.

[0079] The second elastic element 550 provides a force to the radially moving element 530 to move in the centrifugal direction, so that the baffle element 510 can be maintained in an initial radial position when not acted upon by the pushing element 540, thus limiting the interlayer pad 200. When the pushing element 540 pushes the radially moving element 530 to move in the centrifugal direction, the second elastic element 550 is compressed, storing elastic potential energy.

[0080] When winding the coil, the winding equipment is started to begin winding the coil on the coil cylinder 100. During the winding process, when the position where a certain interlayer spacer 200 needs to be placed is reached, the axial moving part 520 is first driven by the linear drive to move along the axial direction of the cylinder 100 according to the axial position requirements, so that the corresponding baffle part 510 is moved to the appropriate axial position and aligned with the position where the interlayer spacer 200 needs to be placed.

[0081] Next, after one turn of the coil is wound, the pusher 540 is driven to move axially by the linear drive. The pushing slope 541 of the pusher 540 interacts with the pushed slope 531 of the radial moving member 530, converting the axial force into a radial force, pushing the radial moving member 530 and the baffle member 510 to move in the centrifugal direction, reducing the obstruction to the interlayer spacer 200 in this row. At this time, the first elastic member 330 pushes out the interlayer spacer 200 in the feed hole 310, increasing the length of the interlayer spacer 200 through the cylinder 100 and the insertion hole 110, thus separating this turn of the coil. Throughout the winding process, the above operation is repeated, and the interlayer spacer 200 of different turns is gradually extended through the sequential action of radial and axial movement.

[0082] Through the coordinated action of the axial moving component 520, the radial moving component 530, and the pushing component 540, the baffle component 510 can be precisely adjusted in both the axial and radial dimensions, achieving precise control over the three-dimensional position of the interlayer spacer 200. This allows the equipment to adapt to various complex coil winding processes. Regardless of the number of turns, wire diameter, or winding method of the coils, it ensures that the interlayer spacer 200 is accurately placed in the predetermined position, improving the accuracy of the interlayer spacer 200 placement and guaranteeing the high accuracy of the insulation distance between adjacent coils.

[0083] The second elastic element 550 allows the baffle element 510 to adaptively adjust its position under different operating conditions. When the pusher 540 is activated, the baffle element 510 can flexibly move radially to remove its obstruction of the interlayer spacer 200; after the pusher 540 removes its force, it can quickly return to its initial position, preparing for the next limiting operation. This adaptive adjustment capability improves the stability and reliability of the limiting assembly 500, ensuring that the limiting control of the interlayer spacer 200 remains precise throughout the entire coil winding process.

[0084] Because the limiting component 500 can flexibly adjust the position of the baffle 510 in both axial and radial directions, the equipment can adapt to the winding requirements of different specifications of coils. Whether it is a small transformer with a fine wire diameter and multiple layers of coils, or a large transformer with a thick wire diameter and fewer layers of coils, the interlayer spacer 200 can be accurately placed by adjusting the parameters of the limiting component 500, which improves the versatility and applicability of the equipment and reduces the cost for enterprises to replace equipment when producing different specifications of products.

[0085] Whether for automatic or manual winding, the limiting component 500 works seamlessly with the winding process. Through a preset program controlling the linear drive component during automatic winding or manual winding by the operator, precise control of the axial movement component 520 and the pushing component 540 is achieved. This satisfies the requirements of different winding methods regarding the timing and position of the interlayer spacer 200, further expanding the equipment's application range.

[0086] The precise control of the limiting component 500 makes the placement process of the interlayer spacer 200 smoother and more efficient. Automated axial and radial adjustments reduce manual intervention and adjustment time, increasing coil winding speed. Simultaneously, the accurate placement of the interlayer spacer 200 avoids winding interruptions and rework caused by improper spacer placement, further improving production efficiency.
