Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and in particular to a coil winding device for transformer manufacturing. Background Technology

[0002] The coil winding device for transformer manufacturing is a special equipment used for automated processing of transformer coils. Because of its functions of precision wiring and layering, constant tension control, high precision and high efficiency coil forming, it has been widely used in power equipment, communication equipment, and especially in the field of transformer assembly.

[0003] In the existing technology, most coil winding devices used in transformer manufacturing use wire guides for wire arrangement. Because the independent reciprocating motion of the wire guide dynamically changes the path length and angle of the wire from the supply point to the winding point, the wire tension fluctuates uncontrollably. This is especially true at the coil end fold, where the tension change is more obvious. Unstable tension can lead to wire stretching and deformation, and uneven coil tightness, which seriously affects the electrical and mechanical performance of the transformer.

[0006] In a further technical solution, the fixing mechanism includes a fixing plate; the fixing plate is slidably connected to the rotating shaft; a connecting plate is rotatably connected to the outer wall of the fixing plate; a pair of bolts are threadedly connected to the top of the outer wall of the connecting plate, and the pair of bolts penetrate the connecting plate; a pair of threaded through slots are opened at the top of the outer wall of the placement plate, and the pair of threaded through slots are respectively matched with a pair of bolts; the bottom end of the outer wall of the rotating column extends into the workbench; a sprocket is fixedly connected to the outer walls of both the rotating shaft and the rotating column, and the pair of sprockets are connected by a chain.

[0007] In a further technical solution, a reciprocating rod is rotatably connected to one side of the outer wall of the reciprocating plate via a square plate; a sprocket is fixedly connected to the outer wall of the reciprocating rod and the bottom of the outer wall of the sliding plate, and a pair of sprockets are connected by a chain; a reciprocating block is provided on the outer wall of the reciprocating rod; an auxiliary tube is fixedly connected to one end of the outer wall of the reciprocating block; a limiting plate is fixedly connected to one side of the outer wall of the square plate, and the limiting plate is slidably connected to the reciprocating block.

[0009] In a further technical solution, the outer wall of the annular block is slidably connected to the inner wall of the rotating tube; one side of the outer wall of the rotating tube is rotatably connected to a reciprocating rod two via a block one, and the reciprocating rod two and the annular block are in a reciprocating connection relationship; one end of the outer wall of the reciprocating rod two is fixedly connected to an eighth gear; the outer wall of the auxiliary tube is fixedly connected to an annular rack via a connecting rod, and the annular rack meshes with the eighth gear; one end of the outer wall of the block one is fixedly connected to an annular protective shell.

[0010] In a further technical solution, the linkage speed between the rotating shaft and the reciprocating shaft follows the helical path topology modeling principle, and the specific steps include: S201: Real-time synchronization of angular displacement data of transformer bobbin as it rotates with the rotating shaft, and extraction of helix angle gradient vector on the surface of the winding layer; S202: Transform the spiral angle gradient vector into path distribution characteristics in a spatial coordinate system to generate an instantaneous wiring topology lattice set that reflects the real-time trajectory of the winding.

[0011] In a further technical solution, the driving device performs nonlinear tension compensation based on the instantaneous cable topology lattice set, specifically including the following steps: S301: Using the instantaneous wiring topology matrix set as the computing power input, based on the variational path prediction algorithm, the dynamic path length change rate between the winding point and the conductor supply point is calculated in real time, and the geometric singularity points that cause the tension change are identified in this way. S302: The geometric singularity point is converted into a nonlinear speed compensation gain for the reciprocating shaft. By fine-tuning the instantaneous meshing response state of gear one, the winding path length is kept differentially constant in the three-dimensional space dimension, thereby achieving zero-fluctuation constant tension winding between coil layers.

[0012] In a further technical solution, the wiring trajectory of the auxiliary tube is generated by the circumferential power conversion of the reciprocating rod, and the specific steps include: S401: Captures the circumferential power output of the sliding plate as it rotates with the rotating shaft, and reduces the speed and increases the torsion through the preset transmission ratio between sprocket two and chain two; S402: The converted power is applied to reciprocating rod one, and the reciprocating constraint relationship between reciprocating rod one and reciprocating block is used to generate the reference reciprocating oscillation vector of the auxiliary tube in the vertical axis.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the rotating shaft is driven by the drive device, the inner wall protrusion of the sliding plate is slidably connected to the groove on the outer wall of the rotating shaft, causing the rotating shaft to drive the sliding plate to rotate. The sliding plate then drives the transformer bobbin to rotate, enabling the transformer bobbin to perform a winding operation. Simultaneously, the rotating shaft drives the reciprocating shaft to rotate through a pair of gears. Since the reciprocating shaft and the reciprocating plate are reciprocatingly connected, the reciprocating shaft drives the reciprocating plate to perform reciprocating motion, causing the sliding plate and the transformer bobbin to move up and down reciprocally. This allows the transformer bobbin to rotate while performing the winding operation, and simultaneously move up and down to adjust the winding position of the transformer bobbin. As a result, the path length between the winding point of the transformer bobbin and the conductor supply point on the wire feeding device becomes shorter, more stable, and geometrically predictable, eliminating the most significant dynamic interference variable. This makes the winding of the transformer bobbin more stable and solves the problem of unstable wire tension caused by the continuous dynamic changes in the path length and angle from the supply point to the winding point.

[0016] 2. As the rotating tube reciprocates along with the auxiliary tube, the fifth gear on the rotating tube meshes with the fifth rack, and the fifth rack is fixed to the limit plate by the connecting block and cannot move. When the fifth gear moves up and down, it rotates through the fifth rack, which drives the rotating tube, the annular block and the cleaning layer to rotate. This allows the guide to be cleaned by the cleaning layer before winding, and the rotation of the cleaning layer further improves the cleaning effect, ensuring the cleanliness of the conductor surface and avoiding winding quality problems caused by impurities or dirt on the conductor surface.

[0019] The technical solution of the present invention will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-8As shown, a coil winding device for transformer manufacturing includes a workbench 1; a rotating column 2 is rotatably connected to the top of the outer wall of the workbench 1; a placement plate 3 is fixedly connected to the outer wall of the rotating column 2; a wire feeding device 4 is placed on the top of the outer wall of the placement plate 3; a driving device 5 is fixedly connected to the bottom of the inner wall of the workbench 1; a rotating shaft 6 is provided at the output end of the driving device 5, and the rotating shaft 6 passes through the workbench 1; a sliding plate 7 is slidably connected to the inner wall of the rotating shaft 6; a transformer frame 8 is placed on the top of the outer wall of the sliding plate 7; and a wire feeding device 4 is provided on the outer wall of the rotating shaft 6. The transformer frame 8 is fixed by a fixing mechanism; a reciprocating shaft 9 is rotatably connected to the top of the inner wall of the workbench 1, and the top of the outer wall of the reciprocating shaft 9 penetrates the workbench 1; gears 10 are fixed to the outer walls of both the reciprocating shaft 9 and the rotating shaft 6, and a pair of gears 10 mesh; a reciprocating plate 11 is provided on the outer wall of the reciprocating shaft 9, and the inner wall of the reciprocating plate 11 is rotatably connected to the outer wall of the sliding plate 7; by placing the transformer frame 8 on the sliding plate 7 and fixing it by the fixing mechanism, the wires on the wire feeding device 4 on the placement plate 3 are fed... The device is installed on the transformer frame 8. When the drive device 5 drives the rotating shaft 6 to rotate, the inner wall protrusion of the sliding plate 7 is slidably connected to the groove on the outer wall of the rotating shaft 6, causing the rotating shaft 6 to drive the sliding plate 7 to rotate. The sliding plate 7 drives the transformer frame 8 to rotate, allowing the transformer frame 8 to perform a winding operation. At the same time, the rotating shaft 6 drives the reciprocating shaft 9 to rotate through a pair of gears 10. Since the reciprocating shaft 9 and the reciprocating plate 11 are reciprocatingly connected, the reciprocating shaft 9 drives the reciprocating plate 11 to perform reciprocating motion. The reciprocating plate 11 drives the sliding plate 7 and the transformer frame 8 to move up and down reciprocally. This allows the transformer frame 8 to rotate while performing the winding operation and move up and down to adjust the winding position of the transformer frame 8. As a result, the path length between the winding point of the transformer frame 8 and the wire supply point on the wire feeding device 4 becomes short, stable, and geometrically predictable, eliminating the most important dynamic interference variable. This makes the winding of the transformer frame 8 more stable and solves the problem of unstable wire tension caused by the continuous dynamic changes in the path length and angle from the supply point to the winding point.

[0021] A reciprocating rod 19 is rotatably connected to one side of the outer wall of the reciprocating plate 11 via a square plate 18; a sprocket 20 is fixedly connected to the outer wall of the reciprocating rod 19 and the bottom of the outer wall of the sliding plate 7, and a pair of sprockets 20 are connected by a chain 21; a reciprocating block 22 is provided on the outer wall of the reciprocating rod 19; an auxiliary tube 23 is fixedly connected to one end of the outer wall of the reciprocating block 22; a limiting plate 24 is fixedly connected to one side of the outer wall of the square plate 18, and the limiting plate 24 is slidably connected to the reciprocating block 22; when the wire is placed between the transformer frame 8, so that the wire passes through the auxiliary tube 23, when the sliding plate 7 rotates with the rotating shaft 6, because the sprockets 20 are fixedly connected to the outer wall of the reciprocating rod 19 and the bottom of the outer wall of the sliding plate 7, and a pair of sprockets 20 are connected by a chain 21, the sliding plate 7 drives the reciprocating rod 19 to rotate through the sprockets 20 and the chain 21, because the reciprocating rod 19 and the reciprocating block 22 are reciprocatingly connected. In this connection, the rotation of the reciprocating rod 19 drives the reciprocating block 22 and the auxiliary tube 23 to move up and down reciprocally, arranging the wires. The guide tube 23 moves up and down reciprocally, assisting the transformer frame 8 in winding, saving the use of wire arranging equipment and reducing costs. At the same time, the up and down reciprocating motion of the auxiliary tube 23 cooperates with the rotation and winding of the transformer frame 8, so that the wires can be wound more evenly and tightly on the transformer frame 8, improving the quality and efficiency of winding, reducing the number of manual interventions and adjustments, reducing the difficulty of operation and labor intensity, and improving the automation level of the production process. The setting of the limit plate 24 plays a precise guiding and limiting role in the movement of the reciprocating block 22, effectively solving the problems of unstable wire tension and poor winding quality in the winding process of transformer manufacturing coils in the prior art, providing a strong guarantee for the efficient and stable production of transformers.

[0022] A rotating tube 25 is rotatably connected to one end of the outer wall of the auxiliary tube 23; an annular block 26 is provided on the inner side wall of the rotating tube 25; a cleaning layer 27 is fixedly connected to the inner side wall of the annular block 26; a fifth gear 28 is fixedly connected to the outer side wall of the rotating tube 25; a fifth rack 29 is fixedly connected to one side of the outer wall of the limiting plate 24 through a connecting block, and the fifth rack 29 and the fifth gear 28 mesh with each other. Before the wire passes through the auxiliary tube 23, the wire first passes through the cleaning layer 27 on the annular block 26 inside the rotating tube 25. When the rotating tube 25 reciprocates with the auxiliary tube 23, the fifth gear 28 on the rotating tube 25 meshes with the fifth rack 29, and the fifth rack 29 is fixed to the limiting plate through the connecting block. The plate 24 cannot move, so when the fifth gear 28 moves up and down, it rotates through the fifth rack 29, which drives the rotating tube 25, the annular block 26 and the cleaning layer 27 to rotate. Before the wire is wound, it is cleaned by the cleaning layer 27, and the rotation of the cleaning layer 27 further improves the cleaning effect, ensuring the cleanliness of the wire surface and avoiding problems with the winding quality caused by impurities or dirt on the wire surface. At the same time, no additional power source is required, and it is achieved only by the reciprocating motion of the auxiliary tube 23, which is both energy-saving and environmentally friendly. In addition, the cleaning layer 27 is made of soft and wear-resistant material, which will not damage the wire surface and ensures the stability and durability of long-term use.

[0023] The fixing mechanism includes a fixing plate 12; the fixing plate 12 is slidably connected to the rotating shaft 6; a connecting plate 13 is rotatably connected to the outer wall of the fixing plate 12; a pair of bolts 14 are threadedly connected to the top of the outer wall of the connecting plate 13, and the pair of bolts 14 penetrate the connecting plate 13; a pair of threaded through slots 15 are opened at the top of the outer wall of the placement plate 3, and the pair of threaded through slots 15 are respectively matched with a pair of bolts 14; the bottom end of the outer wall of the rotating column 2 extends into the workbench 1; sprockets 16 are fixedly connected to the outer walls of both the rotating shaft 6 and the rotating column 2, and the pair of sprockets 16 are connected by a chain 17; by inserting the internal protrusion of the fixing plate 12 into the groove on the outer wall of the rotating shaft 6, the fixing plate 12 presses against the transformer frame 8, and the bolts 14 on the connecting plate 13 are rotated to engage the placement plate 3. Within the threaded groove 15 on the mounting plate 3, the fixed plate 12, in conjunction with the sliding plate 7, clamps the transformer frame 8. When the rotating shaft 6 drives the fixed plate 12 and the sliding plate 7 to rotate, it drives the transformer frame 8 to rotate, causing it to wind. The rotation of the fixed plate 12 and the sliding plate 7 not only does not affect the up-and-down reciprocating motion of the reciprocating plate 11, but also makes the transformer frame 8 rotate and wind more stably. At the same time, through the connection of the sprocket 16 and the chain 17, the rotating column 2 can rotate synchronously with the rotating shaft 6, driving the mounting plate 3 and the wire feeding device 4 to rotate synchronously. The wire feeding device 4 feeds or retracts wire through the rotation of the rotating shaft 6, making it less likely for the wire to loosen when the wire feeding device 4 is feeding, and also making it less likely for the coil to be uneven when the transformer frame 8 is winding.

[0024] The outer wall of the annular block 26 is slidably connected to the inner wall of the rotating tube 25; one side of the outer wall of the rotating tube 25 is rotatably connected to the reciprocating rod 30 via the first block, and the reciprocating rod 30 and the annular block 26 are reciprocatingly connected; one end of the outer wall of the reciprocating rod 30 is fixedly connected to the eighth gear 31; the outer wall of the auxiliary tube 23 is fixedly connected to the annular rack 32 that meshes with the eighth gear 31 via the connecting rod; one end of the outer wall of the first block is fixedly connected to the annular protective shell 33; when the rotating tube 25 rotates, the rotating tube 25 drives the reciprocating rod 30 and the eighth gear 31 on it to rotate via the first block. Because the eighth gear 31 meshes with the annular rack 32, and the annular rack 32 is fixed to the auxiliary tube 23 via the connecting tube and will not rotate, the eighth gear 31 rotates through the rotation of the annular rack 32, causing... The reciprocating rod 20 rotates, and because the reciprocating rod 20 and the annular block 26 are reciprocatingly connected, the rotation of the reciprocating rod 20 drives the annular block 26 to reciprocate. This causes the annular block 26 to rotate while simultaneously reciprocating, thus wiping the wire and further improving the wire cleaning effect. This enhances the cleaning efficiency of the cleaning layer 27 on the wire surface, effectively removing tiny particles and stubborn stains from the wire surface, further ensuring the purity of the winding process and product quality. The annular protective shell 33 separates the wire from the eighth gear 31, preventing the wire from coming into contact with the eighth gear 31 and being worn by it, and also preventing the wire from getting stuck on the eighth gear 31 and preventing it from moving normally. This ensures the smoothness and stability of the entire winding process.

[0025] In use, the transformer frame 8 is placed on the sliding plate 7, and the internal protrusion of the fixing plate 12 is inserted into the groove on the outer wall of the rotating shaft 6, so that the fixing plate 12 presses down on the transformer frame 8. At this time, the bolt 14 on the connecting plate 13 is rotated to be inserted into the threaded groove 15 on the placement plate 3. The fixing plate 12, together with the sliding plate 7, clamps the transformer frame 8. The wires on the wire feeding device 4 on the placement plate 3 are passed through the rotating tube 25 and the auxiliary tube 23 and placed on the transformer frame 8.

[0026] When the drive device 5 drives the rotating shaft 6 to rotate, the inner wall protrusions of the sliding plate 7 and the fixed plate 12 are slidably connected in the grooves on the outer wall of the rotating shaft 6. The rotating shaft 6 drives the sliding plate 7 and the fixed plate 12 to rotate, and the transformer skeleton 8 held by the fixed plate 12 and the sliding plate 7 rotates accordingly to perform the winding operation. At the same time, the rotating shaft 6 drives the reciprocating shaft 9 to rotate through a pair of gears 10. Since the reciprocating shaft 9 and the reciprocating plate 11 are reciprocatingly connected, the reciprocating shaft 9 drives the reciprocating plate 11 to perform reciprocating motion. The reciprocating plate 11 drives the sliding plate 7 and the transformer skeleton 8 to move up and down reciprocally. This allows the transformer skeleton 8 to rotate while performing the winding operation and move up and down reciprocally to adjust the winding position of the transformer skeleton 8. As a result, the path length between the winding point of the transformer skeleton 8 and the wire supply point on the wire feeding device 4 becomes short, stable, and geometrically predictable, eliminating the most important dynamic interference variable and making the transformer skeleton 8 more stable when winding.

[0027] When the sliding plate 7 rotates with the rotating shaft 6, sprockets 20 are fixedly connected to the outer wall of the reciprocating rod 19 and the bottom of the outer wall of the sliding plate 7, and the pair of sprockets 20 are connected by a chain 21. This causes the sliding plate 7 to drive the reciprocating rod 19 to rotate via the sprockets 20 and the chain 21. Since the reciprocating rod 19 and the reciprocating block 22 are reciprocatingly connected, the rotation of the reciprocating rod 19 drives the reciprocating block 22 and the auxiliary tube 23 to move up and down reciprocally, thus arranging the wires. This causes the guide tube 23 to move up and down reciprocally, assisting the transformer frame 8 in winding the wires, thereby saving the use of wire arranging equipment and reducing costs. At the same time, the auxiliary tube 23 also drives the reciprocating block 22 and the auxiliary tube 23 to move up and down reciprocally, thus assisting the transformer frame 8 in winding the wires. This saves the use of wire arranging equipment and reduces costs. The reciprocating motion of the auxiliary tube 23, in conjunction with the rotating winding of the transformer bobbin 8, allows the conductor to be wound more evenly and tightly on the transformer bobbin 8, improving the quality and efficiency of winding, reducing the number of manual interventions and adjustments, lowering the difficulty of operation and labor intensity, and increasing the degree of automation in the production process. The setting of the limit plate 24 plays a precise guiding and limiting role in the movement of the reciprocating block 22, effectively solving the problems of unstable wire tension and poor winding quality in the winding process of transformer manufacturing coils in the prior art, and providing a strong guarantee for the efficient and stable production of transformers.

[0028] As the rotating tube 25 reciprocates along with the auxiliary tube 23, the fifth gear 28 on the rotating tube 25 meshes with the fifth rack 29, and the fifth rack 29 is fixed to the limiting plate 24 by the connecting block and cannot move. When the fifth gear 28 moves up and down, it rotates through the fifth rack 29, which drives the rotating tube 25, the annular block 26 and the cleaning layer 27 to rotate. This allows the wire to be cleaned by the cleaning layer 27 before winding. The rotation of the cleaning layer 27 further improves the cleaning effect, ensuring the cleanliness of the wire surface and avoiding problems with winding quality caused by impurities or dirt on the wire surface. At the same time, no additional power source is required, and it is achieved only by the reciprocating motion of the auxiliary tube 23, which is both energy-saving and environmentally friendly. In addition, the cleaning layer 27 is made of soft and wear-resistant material, which will not damage the wire surface and ensures long-term stability and durability.

[0029] The rotating tube 25 drives the reciprocating rod 30 and the eighth gear 31 on it to rotate through the block 1. Since the eighth gear 31 meshes with the ring rack 32 and the ring rack 32 is fixed to the auxiliary tube 23 through the connecting tube and does not rotate, when the eighth gear 31 rotates, it drives the reciprocating rod 30 to rotate through the rotation of the ring rack 32. Since the reciprocating rod 30 and the ring block 26 are reciprocating connected, the rotation of the reciprocating rod 30 drives the ring block 26 to reciprocate. This causes the ring block 26 to drive the cleaning layer 27 to rotate while reciprocating, thus wiping the cleaning layer 27, improving the cleaning effect of the wire, enhancing the cleaning efficiency of the cleaning layer 27 on the surface of the wire, and further ensuring the purity of the winding process and the quality of the product. The annular protective shell 33 separates the wire from the eighth gear 31, making it difficult for the wire to come into contact with the eighth gear 31 and be worn by the eighth gear 31. It also makes it difficult for the wire to get stuck on the eighth gear 31 and prevent the eighth gear 31 from moving normally, thus ensuring the smoothness and stability of the entire winding process.

[0030] The linkage speed between the rotating shaft 6 and the reciprocating shaft 9 follows the spiral path topology modeling principle, and the specific steps include: S201: Real-time synchronous transformer bobbin 8 rotates with rotating shaft 6 angular displacement data, extracting the helical rise angle gradient vector of the winding layer surface. The specific implementation process is as follows: The rotating shaft of a high-precision rotary encoder, such as an incremental photoelectric encoder, is coaxially mechanically coupled to the rotating shaft 6 at the output end of the drive device 5 via a flexible coupling, ensuring synchronous rotation of the encoder shaft and rotating shaft 6 without relative slippage. When the drive device 5 drives the rotating shaft 6 and transformer bobbin 8 to rotate, the photoelectric conversion device inside the encoder generates two orthogonal pulse signals with a 90° phase difference and one zero-position pulse signal. The controller, such as a PLC or high-speed motion control card, uses a high-speed counting interface to capture the orthogonal pulse signals in real time and uses a quadruple frequency multiplication technique to count and accumulate the rising and falling edges of the A / B phase signals. By judging the phase lead or lag relationship of the A / B phase signals, the real-time rotation direction of the rotating shaft 6 is determined, defining the number of lines of the rotary encoder, i.e., the resolution. , Unit: pulses / cycle, real-time count value Then the real-time rotational angular displacement of the rotating shaft 6 and the transformer frame 8 fixed thereto. The calculation formula is ,or Before the start of each winding cycle, the system measures the count value by capturing the Z-phase zero-position pulse signal. Perform a zeroing and reset to eliminate accumulated errors in the real-time rotational angular displacement. At a high sampling frequency, such as above 10kHz, it is synchronously transmitted to the central processing unit, with the central rotation axis of the transformer frame 8 as the coordinate. The axis is defined with the geometric center of the bottom surface of transformer frame 8 as the origin of the coordinate system. , in perpendicular to Establish a polar coordinate system in the plane of the axis, and construct a cylindrical coordinate system to describe the trajectory of the winding conductor. Among them, the real-time angular displacement data refers to the transformer frame 8 relative to the initial reference position. The angle value rotated by the axis is used to extract the surface value of the winding layer to determine the current conductor landing point on the cylindrical surface formed by the outer diameter of the skeleton or the outer diameter of the already wound wire layer, based on the preset conductor diameter parameters. With real-time angular displacement Calculate the trajectory of the conductor within the current rotation period. Theoretical axial displacement in the axial direction, extracting the real-time helix angle. helix angle Defined as the direction of the tangent to the centerline of the conductor being perpendicular to the axis. The angle between the horizontal planes satisfies the mathematical relationship... , here For the winding pitch, Let be the rotation radius of the current layer of the skeleton, and be the helix angle. By performing directional derivative calculations in the spatial coordinate dimension, the rate of change and directional trend of the change in the topology of the skeleton surface are obtained, generating a helical rise angle gradient vector that characterizes the geometric features of the winding path. , which serves as the core topological parameter reflecting the nonlinear fluctuations of the winding trajectory.

Using the gradient components as the independent variable, a line integral is performed along the trajectory of the wire to restore the abstract rate of change of angle to the real-time geometric state of the wire in the spatial coordinate system. Based on the restored geometric state, the geometric parameters of the projection path are extracted, specifically including: geodesic curvature. It is used to characterize the curvature of the conductor trajectory after it unfolds on the surface of the skeleton 8, and is a key indicator for determining whether the conductor has sideslipped.

The aforementioned path distribution characteristics are discretized, and key geometric control points of the traverse path are extracted in three-dimensional space with equal arc length steps. The instantaneous coordinates of the control points in the rectangular coordinate system are then calculated. ,in , , The instantaneous axial height of the sliding plate 7, driven by the up-and-down movement of the reciprocating shaft 9, is used to topologically correlate the extracted control points according to the winding sequence, forming a data matrix with spatiotemporal continuity, i.e., the instantaneous wiring topology lattice set. Each element Each includes three-dimensional spatial displacement components and corresponding phase weights, outlining the dynamic trajectory flow of the conductor from the wire laying device 4 through the auxiliary pipe 23 to the winding point of the transformer skeleton 8. As the underlying topological feature describing the real-time state of the winding, it reflects the trajectory offset trend caused by the reciprocating shaft 9's directional movement.

[0032] The drive unit 5 performs nonlinear tension compensation based on the instantaneous cable topology lattice set. The specific steps include: S301: Using the instantaneous wiring topology lattice set as the computing power input, and based on the variational path prediction algorithm, the dynamic path length change rate between the winding point and the conductor supply point is calculated in real time, and the geometric singularity points that cause tension abrupt changes are identified accordingly. The specific implementation process is as follows: The instantaneous wiring topology lattice set containing three-dimensional coordinates and phase weights generated in step S202 is imported into the pre-calculation module of the central control unit, and the geometric center of the outlet of the auxiliary tube 23 is defined as the conductor supply point. Define the point where the conductor of the current layer on the surface of transformer bobbin 8 falls as the winding point. Based on the variational path prediction algorithm, a method for predicting the length of a suspended segment of a conductor in space is constructed. functional equations The Euler-Lagrange equations are used to fit the trajectory and extrapolate the trend of discrete control points in the lattice set. The specific implementation process is as follows: Obtain the instantaneous wiring topology lattice set generated in step S202. This set of points represents the discrete geometric distribution of the conductor on the surface of transformer frame 8, transforming the discrete points into a continuous and predictable trajectory, and defining the conductor in the spatial coordinate system. Lagrange function under In the physical scenario of transformer winding, this function is defined as the difference between the tension potential energy and the kinetic energy of the conductor. It is used to describe the most stable natural physical configuration of the conductor in the suspended section, i.e., between the auxiliary tube 23 and the winding point of the transformer frame 8. Through the principle of variational method, the Euler-Lagrange equation is introduced. The discrete control points in the lattice set are substituted as boundary constraints into the equation for solution. The physical meaning of this equation lies in finding a functional that minimizes the energy fluctuation of the conductor tension. The minimized geodesic path is used to perform high-order spline fitting on discrete points through a numerical iterative algorithm, generating a smooth, continuous spatial curve equation that passes through or approximates all control points. This completes the mapping and fitting from the discrete point lattice to the continuous trajectory function, eliminating nonlinear noise caused by mechanical vibration or sampling intervals. Based on the obtained continuous fitted trajectory, the current rotational angular velocity output by the drive device 5 and the axial movement rate vector of the reciprocating shaft 9 are extracted in real time. These real-time motion parameters are used as evolution variables, and the fitted spatial curve equation is expanded in the time dimension using Taylor series. Specifically, at the current moment... Using the coordinates of the reference point and combining the angular displacement change trend determined by the driving device 5, the prediction for the next sampling period is made. The expected topological location of the inner conductor winding point on the surface of transformer frame 8 enables control over the spatial path of the conductor. Extrapolating the trend, predicting the next tiny sampling period Internal supply points With entanglement point Real-time spatial span between Through the Execution regarding time First derivative calculation to extract the dynamic path length change rate in real time. This is used to characterize the expansion and contraction speed of the physical path of the conductor caused by the rotational coupling between the reciprocating shaft 9 and the transformer frame 8. Execution regarding time The first derivative operation is used to extract the dynamic path length change rate in real time. The specific implementation process is as follows: obtain the traverse space path function predicted by the previous steps. The function is physically defined as the instantaneous Euclidean distance between the geometric center of the outlet of auxiliary tube 2 and the winding landing point on the surface of transformer frame 8. In the real-time computing unit of the control system, a synchronous sampling sequence based on a high-precision system clock is established, and a constant time sampling step size is set. For example, between 1ms and 10ms, the current sampling point is acquired synchronously. path length value Compared with the previous sampling point path length value The path length value is processed with respect to time using a first-order backward difference operator. The numerical differentiation operation has the following computational model: Real-time calculation and extraction of dynamic path length change rate Among them, the rate of change of dynamic path length The physical significance lies in quantitatively characterizing the composite path expansion and contraction rate generated when the transformer bobbin 8 rotates with the rotating shaft 6 for winding operations, due to the axial reciprocating motion driven by the reciprocating shaft 9. The positive and negative polarities of this rate of change correspond to the dynamic extension and contraction states of the spatial path, respectively. It intuitively reflects the instantaneous tension disturbance trend of the conductor between the wire feeding device 4 and the winding point caused by the independent reciprocating motion of the mechanical mechanism. By extracting this rate of change in real time, the originally invisible and difficult-to-measure geometric path change is transformed into a quantifiable speed characteristic parameter, eliminating dynamic interference variables in tension control. This provides an accurate input reference for the subsequent drive device 5 to perform nonlinear speed compensation based on feedforward control logic, effectively suppressing the problem of conductor tensile deformation or uneven winding tightness caused by dynamic changes in path length. The second derivative of the dynamic path length change rate is calculated. The specific implementation process for obtaining the acceleration characteristics of path changes is as follows: real-time extraction of the dynamic path length change rate. The data stream characterizes the instantaneous expansion and contraction velocity of the conductor along its spatial geometric path due to the combined effects of the rotation of the transformer frame 8 driven by the rotating shaft 6 and the up-and-down movement of the reciprocating plate 11 driven by the reciprocating shaft 9. In the computational kernel of the control system, a second-order central difference operator or a discrete Laplace transform is used to perform a time-dependent operation on the rate of change. The mathematical calculation model for the second derivative is as follows: This generates acceleration features that characterize path changes in real time, where the acceleration features are... At the physical level, this is defined as the dynamic impact intensity of the conductor tension, i.e., the degree of drastic change in the path expansion and contraction speed. By monitoring the amplitude and direction of this acceleration characteristic, the motion reversal impact point in the mechanical linkage process can be identified. When the reciprocating plate 11 moves to the end reversal point of the transformer frame 8, the polarity of the motion vector of the reciprocating shaft 9 is reversed, which will cause the path length to... This results in a nonlinear transition, at which point the second derivative... The instantaneous modulus will exhibit a peak jump, and the peak jump point is defined as a geometric singularity point. This is used to quantify and identify the risk of sudden changes in wire tension caused by the independent reciprocating motion of the wire guide. This acceleration characteristic not only reveals the dynamic evolution trend of path changes, but also provides key dynamic feedforward gain parameters for the subsequent drive device 5 to perform nonlinear speed compensation based on the rate of change of path length. This fundamentally counteracts the tension impact caused by the acceleration and contraction of the path, ensuring the physical consistency of the winding process. It is compared with a preset tension stability threshold. When the absolute value of the path change acceleration exceeds the threshold, or when the rate of change of path switches between positive and negative extreme points, such as the foldback position at the end of the transformer frame, the corresponding spatial coordinates are used. Identify and mark geometric singularity points. Geometric singularity points refer to critical spatial locations where the tension of the conductor undergoes a nonlinear jump due to a change in mechanical motion direction or abrupt change in the geometry of the winding. Identifying these points aims to provide a precise logical trigger reference for the subsequent drive device 5 to perform feedforward nonlinear speed compensation on the reciprocating shaft 9, thereby offsetting the dynamic tension interference caused by abrupt changes in path length.

[0033] S302: The geometric singularity points are transformed into nonlinear velocity compensation gains for the reciprocating shaft 9. By fine-tuning the instantaneous meshing response of gear 10, the winding path length is kept differentially constant in the three-dimensional space, achieving zero-fluctuation constant tension winding between coil layers. The specific implementation process is as follows: The controller extracts the coordinates of the geometric singularity points identified in step S301 and their associated acceleration features in real time. Call the preset non-linear mapping function in memory. ,in The path acceleration is used; by inputting the acceleration feature into this mapping function, the corresponding nonlinear velocity compensation gain is calculated. Nonlinear velocity compensation gain The specific implementation process is as follows: the control system acquires the path change acceleration characteristic quantity output by step S301 in real time. It is used as an independent variable to input a nonlinear mapping function preset in the central processing unit. In, nonlinear mapping function It is a dynamic compensation model pre-established based on the rotational inertia of the transformer frame 8, the mechanical damping of the reciprocating shaft 9, and the meshing clearance of gear 10. Its mathematical form is based on the dynamic working conditions of the transformer frame 8 during the winding process, and incorporates the acceleration characteristic quantity. ,Right now The value space of is divided into different physical response intervals, and a piecewise function framework is constructed. The steady-state linear interval is: when ,in When the preset linear threshold is met, the system is in a stable orbiting state. At this point, the composite model uses a first- or second-order low-order polynomial, and the mapping function is expressed as follows: ,in and It is a constant gain based on the fundamental rotational speed of the drive unit 5 and the standard tension of the conductor, used to maintain the basic path balance of the conductor when it is wound in the middle region of the bobbin 8. Dynamic transition range: when At this point, the system is in the acceleration phase near the end of the skeleton or when the cabling reverses. At this time, the composite model switches to a higher-order polynomial model, whose mathematical form is defined as: ,in, For higher-order terms, ; This is a coupling correction term used to introduce the real-time angular velocity of the rotating shaft 6. Moment of inertia of transformer frame 8 Regarding the impact on compensation gain, the purpose of using a higher-order polynomial is to utilize its nonlinear steepness to fit the physical trend of the conductor tension increasing exponentially with path acceleration, thus offsetting the huge dynamic impact generated during the instantaneous reversal of the reciprocating axis 9. Geometric singularity compensation point: when the acceleration characteristic quantity... When the singularity threshold is reached, the composite model introduces a pulse compensation operator to adjust the meshing response current of gear 10 instantaneously, thereby increasing the gain. A compensation peak is generated in the opposite direction to the path abrupt change, forcibly offsetting the tension abrupt change caused by the jump in spatial geometric path length. In practical applications, the coefficients of the higher-order polynomial are obtained through dynamic simulation experiments on wires of different diameters before winding and stored in the lookup table of the control system. Through this piecewise and higher-order fitting composite logic, the drive device 5 can adaptively output precise speed compensation commands for the path stretching intensity under different winding phases, achieving differential constant winding path length in the entire spatial dimension, and ultimately achieving a zero-fluctuation constant tension winding effect between coil layers. To accurately characterize the nonlinear response relationship between spatial path acceleration and the compensation torque required by drive device 5, the system, during the calculation process, according to... The real-time absolute value and its positive or negative polarity are used to perform dynamic retrieval and interpolation operations in the mapping function to extract the corresponding gain coefficient. Among them, when the acceleration characteristic quantity is in the preset low-amplitude stable range, the gain Following linear mapping logic to maintain a balanced output of the basic tension, when the acceleration characteristic quantity experiences a transient peak jump due to commutation at the 8th end of the transformer frame, the gain... By rapidly amplifying the nonlinear exponential curve in the mapping function, a dynamic feedforward gain that leads the hysteresis effect of the mechanical system is generated. This gain is then used to calculate the nonlinear velocity compensation gain. The motion control loop of the drive unit 5 is superimposed in real time. By adjusting the pulse duty cycle or voltage amplitude of the drive command, the instantaneous axial speed of the reciprocating shaft 9 and its driven sliding plate 7 is directly intervened. This ensures that the dynamic tension impact caused by path acceleration is canceled out by the reverse compensation torque at the moment of generation, achieving adaptive constant tension control under complex winding trajectories. The nonlinear speed compensation gain refers to a non-constant motor speed correction coefficient that dynamically changes with the winding phase. As a feedforward compensation signal superimposed on the axial control loop of the drive device 5, the instantaneous meshing response state between gear 10 and the transmission chain of reciprocating shaft 9 is finely adjusted using a frequency converter or servo driver. The instantaneous meshing response state refers to the compensation angular velocity pulse generated by gear 10 during meshing transmission by changing the instantaneous torque output of the drive device 5, thereby correcting the theoretical displacement velocity of the reciprocating shaft 9 and its driven sliding plate 7 in the vertical axis. In the three-dimensional space dimension, this velocity compensation amount is used to offset the path length change rate predicted in step S301 in real time. The total path length of the conductor from the supply point of the wire-laying device 4 to the winding point of the transformer frame 8. Regarding time The change remains zero, that is... This physical state is defined as differential constant. Through this high-frequency dynamic speed fine-tuning, it is ensured that when the conductor crosses geometrically singular points, such as the end reversal point of the transformer frame, the internal mechanical stress does not change nonlinearly with the change of the path geometry. This eliminates dynamic interference variables at the physical root, realizes zero-fluctuation constant tension control in the process of winding between transformer coil layers, and ensures the consistency of electrical performance of coil forming.

[0034] The cable routing trajectory of auxiliary tube 23 is generated by the circumferential power conversion of reciprocating rod 19, and the specific steps include: S401: Capture the circumferential power output of the sliding plate 7 as it rotates with the rotating shaft 6, and reduce speed and increase torque through a preset transmission ratio between sprocket 20 and chain 21. Specifically, the sliding connection between the protrusions on the inner wall of the sliding plate 7 and the grooves on the outer wall of the rotating shaft 6 allows the sliding plate 7 to have axial sliding freedom along the rotating shaft 6 while being locked in the circumferential dimension for synchronous rotation. When the drive device 5 drives the rotating shaft 6 to rotate, the mechanical energy generated by the rotation of the sliding plate 7 around the axis is defined as the circumferential power output. A sprocket 20 is fixedly installed at the bottom of the outer wall of the sliding plate 7 as the driving sprocket, capturing the circumferential rotational torque of the sliding plate 7 in real time and introducing it into the power transmission chain. The driving sprocket is connected to the square plate 1 via chain 21. Another sprocket 20, i.e., the driven sprocket, is fixed to the outer wall of the reciprocating rod 19 on 8, and is tensioned to form a closed-loop transmission circuit. The preset transmission ratio refers to the ratio of the number of teeth between the driving sprocket and the driven sprocket. By making the number of teeth of the driven sprocket greater than the number of teeth of the driving sprocket, the instantaneous angular velocity of the driven sprocket driving the reciprocating rod 19 to rotate is lower than the angular velocity of the driving sprocket, thus achieving speed reduction in the motion dimension. At the same time, based on the inverse proportional relationship between the rotational speed and torque of mechanical energy transmission, the output torque at the end of the reciprocating rod 19 is amplified while the rotational speed is reduced, thus completing the torsion amplification. This is intended to provide a stable driving force sufficient to overcome mechanical friction and wire tension resistance for the reciprocating block 22 and its fixed auxiliary tube 23 to move up and down on the limiting plate 24, ensuring the smoothness and accuracy of the wiring action.

[0035] S402: The converted power is applied to the reciprocating rod 19. Utilizing the reciprocating constraint relationship between the reciprocating rod 19 and the reciprocating block 22, a reference reciprocating oscillation vector for the auxiliary tube 23 in the vertical axis is generated. Specifically, the mechanical power, after speed reduction and torque amplification in step S401, is transmitted to the reciprocating rod 19 via the driven sprocket 20, driving the reciprocating rod 19 to perform continuous rotational motion around its geometric center axis. The reciprocating constraint relationship between the reciprocating rod 19 and the reciprocating block 22 refers to the presence of a... A closed reciprocating track groove, such as a bidirectional spiral groove, is formed, and the inner side of the reciprocating block 22 is provided with a slider that slides and engages with the track groove, constituting a mechanical reversing mechanism that converts rotational torque into axial thrust. When the reciprocating rod 19 rotates, the sidewall of the track groove drives the reciprocating block 22 to perform periodic reciprocating linear motion along the vertical axis under the linear limiting constraint of the limiting plate 24. Since the auxiliary tube 23 is fixedly connected to one end of the outer wall of the reciprocating block 22, the auxiliary tube 23 synchronously reciprocates and switches positions with the reciprocating block 22, forming a time-related dynamic relationship in three-dimensional space. The dynamic displacement function is defined as the reference reciprocating oscillation vector. The reference reciprocating oscillation vector specifically covers the real-time height coordinates, reciprocating frequency, and instantaneous commutation speed at the turning point of the auxiliary tube 23 during the wiring process. As a physical reference for the wiring action, it ensures that the auxiliary tube 23 can guide the conductors to be evenly distributed in the axial direction of the transformer frame 8, and complete the high-precision interlayer wiring operation in conjunction with the rotation of the transformer frame 8.

[0036] The cleaning layer 27 inside the rotating tube 25 follows a multi-frequency rotating field conversion logic, and the specific steps include: S501: Using the reference reciprocating oscillation vector as the displacement input, and utilizing the meshing constraint mechanism between the fifth gear 28 fixed on the rotating tube 25 and the fifth rack 29 on the limiting plate 24, the specific implementation process is as follows: Obtain the reference reciprocating oscillation vector generated in step S402. This vector is defined at the physical level as the linear reciprocating displacement performed by the auxiliary tube 23 and the rotating tube 25 it carries along the vertical axis of the limiting plate 24. The fifth rack 29 is fixed to the outer wall of the limiting plate 24 using a connecting block, keeping it static in the spatial coordinate system as a geometric reference for displacement conversion. At the same time, the fifth gear 28 is coaxially fixed to the outer wall of the rotating tube 25, so that the teeth of the fifth gear 28 and the tooth grooves of the fifth rack 29 are in a preset depth of meshing, thus constructing the meshing constraint mechanism. When the auxiliary tube 23 drives the rotating tube 25 to perform axial reciprocating motion along the limiting plate 24 under power drive, due to the interaction force between the fifth gear 28 and the fixed fifth rack 29, the fifth gear 28 is forced to generate controlled rotational motion while moving along the length direction of the rack. During this process, the meshing constraint mechanism maps the linear displacement increment of the reference reciprocating oscillation vector to the angular displacement output of the rotating tube 25 in real time through geometric interference logic, realizing the conversion of the reciprocating mechanical energy of the wiring mechanism into the rotational driving force of the cleaning unit without the need for an additional power source, providing a stable power input for the subsequent formation of a multi-frequency directional rotational field.

[0037] S502: The linear reciprocating motion of the auxiliary tube 23 is forcibly converted into a multi-frequency rotational field of the cleaning layer 27 as the rotating tube 25 rotates. The specific implementation process is as follows: Receive the displacement output generated by the auxiliary tube 23 along the vertical axis in step S501 and use it as the mechanical power source to drive the rotation of the cleaning unit. Since one end of the outer wall of the auxiliary tube 23 is rotatably connected to the rotating tube 25, and the outer wall of the rotating tube 25 is fixedly connected to the fifth gear 28, when the auxiliary tube 23 drives the rotating tube 25 to perform a linear reciprocating motion in the vertical direction, the fifth gear 28 is forced to generate pure rolling due to the meshing constraint of the fifth rack 29 on the limiting plate 24, driving the rotating tube 25 to rotate synchronously around its central axis. Here, "multi-frequency" refers to the fact that the reciprocating speed of the auxiliary tube 23 is nonlinearly controlled by the rotation phase of the reciprocating rod 19, causing the instantaneous angular velocity of the rotating tube 25 to change in different stroke ranges. The state fluctuation exhibits a frequency spectrum distribution characteristic that changes with time. The rotation direction refers to the polarity switch of the rotation direction of the fifth gear 28 as the auxiliary tube 23 moves upward or downward, forming an alternating clockwise and counterclockwise rotation state. By applying mechanical energy with dynamic angular velocity and periodic directional change characteristics to the cleaning layer 27 fixed on the annular block 26 inside the rotating tube 25, the cleaning layer 27 constructs a dynamic region with a nonlinear angular velocity vector distribution and high-frequency tangential impulse within the cylindrical inner cavity of the rotating tube 25, which is defined as a multi-frequency rotation field. This rotation field applies multi-dimensional rotational centrifugal force and tangential wiping force to the surface of the conductor passing through it through the physical contact interface. Without relying on external energy, the adaptive and enhanced cleaning of impurities on the surface of the conductor is achieved through the secondary capture and conversion of the reciprocating power.

[0038] Cleaning layer 27 performs a deep stripping composite wiping process on the wires, including the following steps: S601: Utilizing the reciprocating connection between the reciprocating rod 30 and the annular block 26 driven by the rotation of the rotating tube 25, an axial high-frequency micro-motion component is superimposed within the multi-frequency rotational field. Specifically, when the rotating tube 25 rotates due to the meshing of the fifth gear 28 and the fifth rack 29, the block 1 fixed to one side of the outer wall of the rotating tube 25 synchronously drives the reciprocating rod 30 and its shaft end's eighth gear 31 to perform circumferential follow-up rotation around the conductor axis. Since the eighth gear 31 maintains real-time meshing with the annular rack 32 fixed to the outer wall of the auxiliary tube 23, and the annular rack 32 is stationary in the circumferential dimension, the eighth gear 31 is forced to generate rotational force about the axis of the reciprocating rod 30 during the rotation of the rotating tube 25, constrained by the annular rack 32. Utilizing the reciprocating connection between the reciprocating rod 30 and the annular block 26, this rotational force is forcibly converted into rotational force about the axis of the reciprocating rod 30. The cleaning layer 27 moves back and forth along the axial direction of the inner wall of the rotating tube 25. Since the rotation speed of the rotating tube 25 is much higher than the overall displacement speed of the auxiliary tube 23, the axial back and forth movement generated by the annular block 26 has extremely high frequency characteristics per unit time, which is defined as the high-frequency micro-motion component of the axial direction. This high-frequency micro-motion component is superimposed in real time in the physical space to the multi-frequency rotational field generated by the rotation of the rotating tube 25, so that the motion trajectory of the cleaning layer 27 changes from a single circumferential tangential motion to a spiral oscillation trajectory of rotation-axial composite. Through the dynamic coupling of the rotational field with the axial micro-motion component, the cleaning layer 27 applies an additional high-frequency longitudinal peeling force while performing circumferential surface wiping on the conductor, and constructs an asymmetric mechanical friction field on the surface of the conductor. The aim is to thoroughly crush and peel off stubborn particles and attached dirt on the surface of the conductor through multi-dimensional kinetic energy superposition, providing a wire material foundation with extremely high cleanliness for the transformer winding process.

[0039] S602: By vector superposition of axial high-frequency micro-motion components and multi-frequency rotational fields, an asymmetric stripping dynamic chain is generated for micron-level impurities on the conductor surface. This enables the cleaning layer 27 to perform rotational-axial dual-cooperative composite wiping on the conductor, completing the adaptive enhancement treatment of conductor cleanliness before winding. The specific implementation process is as follows: obtaining the tangential velocity vector generated by the rotation of the rotating tube 25. The axial instantaneous velocity vector generated by the reciprocating rod 20 driving the annular block 26 A vector space composition operation is performed at the physical interface between the clean layer 27 and the conductor to generate the resultant velocity vector. Due to the tangential vector Constrained by the multi-frequency fluctuation characteristics generated by the reciprocating motion of the fifth gear 28 with the auxiliary tube 23, the axial vector... The reciprocating rod 30 exhibits a periodic, rapid reversal high-frequency characteristic as it rotates. The nonlinear superposition of these two factors causes the fiber ends of the cleaning layer 27 to form a dynamic force transmission path in space that evolves into an asymmetric spiral trajectory. This is defined as an asymmetric peeling dynamic chain. By changing the direction and amplitude of the combined force in real time, the asymmetric peeling dynamic chain breaks the static equilibrium of the adhesion force of micron-sized impurity particles on the surface of the conductor, generating alternating shear stress pointing in the combined tangential and axial directions of the conductor. This forces stubborn impurities to peel off from the conductor matrix. During the wiping action, the circumferential rotation of the cleaning layer 27 is responsible for peeling. In addition to circumferentially distributed dust and dirt, the superimposed axial high-frequency micro-motion generates an axial pulse impact similar to high-frequency rubbing. This rotary-axial dual-coordinated composite wiping mode can adaptively capture and remove tiny particles from the micro-pits on the wire surface as the wire passes through the rotating tube 25 at high speed. Through this enhanced cleaning mechanism that relies entirely on the energy conversion of the wire laying mechanism, the surface cleanliness level of the wire before entering the transformer frame 8 is significantly improved, eliminating the hidden danger of interlayer insulation breakdown caused by foreign matter on the wire surface, and realizing adaptive enhancement of the wire pretreatment quality in the winding process.
