Description
Technical Field
[0001] This invention relates to the field of transformer coil winding technology, and more specifically to a transformer coil winding mechanism. Background Technology
[0002] A transformer coil winding mechanism is a specialized piece of equipment used for winding and forming conductors during transformer production, falling under the category of transformer manufacturing equipment. This type of equipment uses a winding roller as the base structure for coil forming. An external drive device rotates the roller at a uniform speed, and guiding and tensioning components control the wire's transport path and winding posture, winding the wire in an orderly manner according to preset turns and arrangement requirements, ultimately forming a transformer coil with specific electrical parameters. A conventional winding mechanism typically consists of basic units such as a support assembly, winding roller, steering and guiding structure, and transmission connection components. The support assembly provides a stable installation reference for each functional component, while the guiding structure adjusts the wire's transport direction and entry position, ensuring basic wire routing order during the winding process.
[0003] The guide output position of conventional winding mechanisms is mostly fixed. When using irregularly shaped winding rollers such as elliptical ones for coil winding, it is impossible to adjust the output height of the wire body synchronously with the radial dimension changes during the rotation of the winding roller. It is also difficult to adapt to the axial offset generated during the winding process. This easily leads to the wire body and the outer side of the winding roller not maintaining a perpendicular fit. This results in significant differences in winding pressure at different circumferential positions of the coil, which in turn causes uneven compactness between coil layers and the appearance of loose gaps in some areas. This directly affects the overall structural stability and electrical performance of the coil, and has long restricted the finished product quality and production efficiency of irregularly shaped transformer coils.
[0004] In view of the actual defects in the existing technology, a mature synchronous adaptation solution has not yet been formed, and there is an urgent need to optimize and improve the guiding and linkage transmission structure of the transformer coil winding mechanism. Summary of the Invention

[0010] Preferably, both ends of the top of the support slide rail are connected to traction ropes; guide slide rails are symmetrically arranged on the inner side of the two sets of first side plates near the bottom of the winding roller, and second sliders are slidably mounted on the outer side of the guide slide rails, and the other end of the traction rope is fastened to the second slider; multiple sets of fixed pulleys are arranged on the inner side of the first side plate for steering and supporting the traction rope.
[0011] Preferably, a limiting roller is provided at one end of the second slider facing the winding roller, and the outer side of the limiting roller is in contact with the bottom of the outer side of the winding roller; a second spring is provided at the bottom of the second slider, and the lower end of the second spring is fastened to the base plate to push the second slider so that the limiting roller is always in contact with the outer side of the winding roller.
[0012] Preferably, the winding roller has an elliptical structure; during the rotation of the winding roller, the outer diameter changes to squeeze the limiting roller, which drives the second slider to move up and down along the guide rail, and the traction rope pulls the support rail to move up and down synchronously, so that the wire output by the output pulley always fits the outer side of the winding roller.
[0013] Preferably, a tension roller assembly is provided on the outer side of the second side plate. The tension roller assembly includes a support block, a first slide groove, a third spring, and a tension roller. The first slide groove is opened inside the second side plate. The support block is slidably assembled up and down along the first slide groove. The third spring is disposed between the bottom of the support block and the bottom of the inner wall of the first slide groove. The tension roller is rotatably disposed at one end of the support block. The conveyor belt passes around the outer side of the tension roller and is then conveyed to the guide pulley.
[0014] Preferably, a support mechanism is provided at the bottom position of the bottom of the winding roller on the top of the base plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention utilizes the linkage between the limiting roller and the elliptical winding roller, along with the traction rope pulling the support slide rail up and down along the first side plate. The height position of the output pulley can be adjusted synchronously with the radial dimension change of the winding roller as it rotates. Combined with the axial reciprocating sliding of the output pulley along the support slide rail, the output wire is always kept in a perpendicular and close contact with the outer side of the winding roller, ensuring consistent winding pressure at all positions of the coil, effectively improving the interlayer compactness of the coil, avoiding the problem of loose gaps, and ensuring the structural stability of the coil.
[0017] 2. This invention synchronously connects the output pulley and rack via a telescopic linkage, and, in conjunction with the transmission structure of the incomplete gear and base, can synchronously drive the deflection of the guide pulley when the output pulley shifts axially. This ensures that the output direction of the guide pulley is always aligned with the output pulley, guaranteeing a smooth conveying path for the yarn and reducing yarn slippage and jamming. At the same time, the tension roller assembly, supported by the elasticity of the third spring, can compensate for tension fluctuations during the yarn conveying process in real time, maintaining the uniformity of winding tension.
[0018] 3. The present invention uses the elastic cooperation between the support slide and the support spring to drive the support roller to form continuous support on the bottom of the winding roller, which can counteract the deflection deformation of the winding roller caused by the increase in the weight of the wire during the winding process, avoid the center of the winding roller from shifting, ensure the winding accuracy of the coil, and the support roller can roll synchronously with the winding roller without causing additional running resistance to the normal rotation of the winding roller.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the following embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0027] Example 1 like Figure 1 , Figure 2As shown, this embodiment provides a transformer coil winding mechanism, including: a support assembly 100 assembled from a base plate 101, a first side plate 102, and a second side plate 103, wherein the first side plate 102 is symmetrically disposed at one end of the top of the base plate 101, and the second side plate 103 is disposed at the other end of the top of the base plate 101. Two sets of first side plates 102 are provided with a winding roller 200 on the side that is close to each other, and the bottom of the winding roller 200 is supported by a support mechanism 700. The central shaft of the winding roller 200 is connected to the bearing seat of the first side plate 102, and one end of the central shaft of the winding roller 200 passes through the first side plate 102 and is connected to the external drive device; the winding roller 200 is driven to rotate by the external drive device. The second side plate 103 has multiple sets of steering rollers 500 on one side, with a wire 800 wound around its outer side. The other end of the wire 800 is wound around the outer side of the winding roller 200. Then, the rotation of the winding roller 200 drives the wire 800 to be evenly wound around the outer side of the winding roller 200, thereby realizing the winding of the coil. A guide mechanism 400 is provided at the center of the top of the base plate 101, wherein the guide mechanism 400 includes a steering pulley 401 rotatably connected to the base plate 101, and the line 800 passes around the outside of the steering pulley 401. A synchronous transmission mechanism 300 is also provided on the side of the two sets of first side plates 102 that are close to each other. The synchronous transmission mechanism 300 includes a support slide rail 302 that is slidably connected to the two sets of first side plates 102. An output pulley 303 is provided on the top of the support slide rail 302. The wire 800 extends from the outside of the steering pulley 401, passes around the output pulley 303, and is wound and connected to the outside of the winding roller 200.
[0028] During the winding process of the winding roller 200, the wire 800 will deviate due to the winding of the winding roller 200. The deviating tension of the wire 800 will drive the output pulley 303 to slide on the outside of the support rail 302, thereby reducing the dispersion of force on the wire 800 in the horizontal and vertical directions of the winding roller 200 and avoiding the phenomenon of misaligned winding of the wire 800.
[0029] like Figures 1 to 6 As shown, the bottom of the steering pulley 401 is provided with a base 405 that is rotatably connected to the top of the base plate 101, and an incomplete gear 404 is provided on the outer side of the base 405. A rack 402 that meshes with the incomplete gear 404 is slidably provided on the top of the base plate 101 near the position of the incomplete gear 404, and a limiting groove 403 that supports the rack 402 to slide horizontally in the longitudinal direction is provided on the top of the base plate 101.
[0030] On the other side of the rack 402, there is a telescopic link 306 that is synchronously connected to the output pulley 303. The telescopic link 306 can move up and down following the support slide rail 302. Meanwhile, the telescopic link 306 is provided with a drive unit on the outside of the support slide rail 302 for sliding displacement. The drive unit drives the telescopic link 306 to slide back and forth on the outside of the support slide rail 302. The drive unit is any of the sliding drive components in the prior art. The sliding drive component includes a drive motor and a sliding seat that is connected to the drive motor. The sliding seat is adapted to be mounted on the outside of the support slide rail 302 and can slide back and forth along the support slide rail 302. The sliding seat is fixedly connected to the telescopic connecting rod 306. The drive motor drives the telescopic connecting rod 306 to perform reciprocating sliding displacement along the outside of the support slide rail 302 through the sliding seat. Its working principle and technical features are consistent with the prior art and will not be described in detail here.
[0031] The telescopic connecting rod 306 drives the output pulley 303 to reciprocate on the top of the support slide rail 302, thereby ensuring that the wire 800 output by the output pulley 303 remains horizontal and vertical to the outer side of the winding roller 200. This ensures that the wire 800 maintains maximum contact force with the outer side of the winding roller 200 during the winding process, thus guaranteeing that the multiple layers of coils on the outer side of the winding roller 200 are tightly compacted, preventing loose gaps in the coils that could affect the quality of the transformer.
[0032] Furthermore, the support slide rail 302 is provided with first sliders 304 extending into the interior of the first side plate 102 on both sides, and the upper and lower ends of the first sliders 304 are provided with first springs 305 that are fastened to the inner wall of the first side plate 102. During the up and down movement of the support slide rail 302, the first springs 305 ensure that the support slide rail 302 connected to the first sliders 304 can be reset normally, avoiding any lag.
[0033] The top two ends of the support slide rail 302 are each connected to a traction rope 301. The inner side of the two sets of first side plates 102 is symmetrically provided with guide slide rails 309 near the bottom of the winding roller 200. The outer side of the guide slide rail 309 is provided with a second slider 311 that slides up and down. The other end of the traction rope 301 is fastened to the second slider 311. The inner side of the first side plate 102 is provided with multiple sets of fixed pulleys 307 that provide steering support for the traction rope 301.
[0034] One end of the second slider 311 is provided with a limiting roller 310. The outer side of the limiting roller 310 is in contact with the bottom of the outer side of the winding roller 200. The bottom of the second slider 311 is provided with a second spring 308 that is fastened to the top of the base plate 101. The second spring 308 supports the second slider 311 to ensure that the limiting roller 310 is always in contact with the outer side of the winding roller 200.
[0035] Since the winding roller 200 has an elliptical structure, during the rotation of the winding roller 200, the winding roller 200 squeezes the limiting roller 310, thereby driving the second slider 311 to slide up and down on the outside of the guide rail 309. The up and down displacement of the second slider 311 pulls the support rail 302 connected to the traction rope 301 to follow the displacement. When the second slider 311 moves downward, the traction rope 301 pulls the support slide rail 302 upward, which in turn causes the output end of the output pulley 303 to move upward, so that the output wire 800 is flush with the top of the winding roller 200, thereby ensuring that the wire 800 is close to the outside of the winding roller 200. When the short diameter surface of the winding roller 200 is in contact with the limiting roller 310, the second slider 311 is subjected to the rebound force of the second spring 308 and moves upward. This causes the support slide rail 302 connected to the traction rope 301 to move downward under the combined action of the rebound force of the first spring 305 and its own weight. Since the traction rope 301 connects the two ends of the second slider 311 and the support slide rail 302, the vertical displacement distances of the two are consistent. This ensures that the distance the support slide rail 302 descends is consistent with the distance the limiting roller 310 moves upward. This ensures that the wire 800 output by the output pulley 303 driven by the support slide rail 302 is in contact with the upper surface of the short diameter surface of the winding roller 200, thus keeping the wire 800 perpendicular to the outer side of the winding roller 200 and ensuring that the coil wound by the wire 800 has consistent pressure.
[0036] Synchronously, as the output pulley 303 outputs the wire 800, a longitudinal pushing force will appear as the wire 800 is wound on the outside of the winding roller 200, causing the wire 800 to deviate. At this time, the output pulley 303 is driven to follow the displacement through the telescopic connecting rod 306, so that the wire 800 output by the output pulley 303 is always perpendicular to the outside of the winding roller 200.
[0037] During the process of the telescopic link 306 driving the output pulley 303 to move, the telescopic link 306 synchronously drives the rack 402 to follow the displacement. The displacement of the rack 402 drives the incomplete gear 404 meshing with it to deflect, thereby causing the steering pulley 401 on the top of the base 405 to follow the deflection. This makes the line 800 output by the steering pulley 401 aligned with the position of the output pulley 303, avoiding slippage or jamming of the line 800 due to the positional deviation of the output pulley 303.
[0038] Furthermore, a tension roller assembly 600 adapted to the line 800 is provided on the outer side of the second side plate 103. The tension roller assembly 600 includes a support block 602 that slides up and down on the side of the second side plate 103. The interior of the second side plate 103 is provided with a first groove 601 that is adapted to the support block 602. The bottom of the support block 602 is provided with a third spring 604 that is fastened to the bottom of the inner wall of the first groove 601. One end of the support block 602 is provided with a tension roller 603, and the line 800 passes around the outside of the tension roller 603 and is transported to the position of the guide pulley 401.
[0039] Furthermore, a support mechanism 700 is provided at the top of the base plate 101 at the bottom position of the winding roller 200. The support mechanism 700 includes two sets of support slides 701 symmetrically arranged on the top of the base plate 101. The support slides 701 are elastically supported by support frames 703. Both ends of the support frames 703 and the interior of the support slides 701 are provided with support springs 702. The tops of the two sets of support frames 703 are jointly supported by two sets of support rollers 704 that fit against the middle of the bottom of the winding roller 200. The support rollers 704 roll as the winding roller 200 rotates. During the process of the winding roller 200 rotating to wind the coil, as the wire 800 continuously winds around the outside of the winding roller 200, the weight of the winding roller 200 continuously increases. Since the winding roller 200 has an elliptical structure, the disturbance at its center position is relatively large during the winding rotation, which can easily cause the coil center to shift. Therefore, by setting a support roller 704 to support the bottom of the winding roller 200, the winding roller 200 is always supported by the support roller 704 during the winding process. As the diameter of the winding roller 200 increases, the support roller 704 is continuously displaced downward under pressure, thereby compressing the support spring 702 and ensuring the space for the displacement of the support roller 704.
[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.
[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment includes only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
