Description

Technical Field

[0001] This invention relates to the field of reactor winding equipment technology, specifically a winding device for reactor production. Background Technology

[0002] As the core power equipment for reactive power compensation and harmonic suppression in the power grid, the quality of the coil winding of the reactor directly determines the temperature rise performance, partial discharge, short-circuit mechanical strength and overall operational stability of the reactor. The winding process is the core and key process in the production of reactors.

[0003] The wires used for reactor winding are divided into round wires and flat wires. When existing reactor winding equipment winds flat wires, the rectangular cross-section of the flat wire has a large width-to-thickness ratio. This causes slight twisting around its own axis during the unwinding, straightening, and conveying process. Even a 1°-2° twist when entering the winding die can lead to uneven coil width and uneven inter-turn gaps, resulting in the insulation layer edge being squeezed and damaged. Traditional guide rollers can only limit left and right offsets and cannot effectively correct the twist of the winding axis.

[0004] Furthermore, the existing reactor winding equipment's mold fixing mechanism is mostly a customized and exclusive structure, lacking universal adaptability and adjustment capabilities. A single machine can only match a single specification of reactor winding mold to complete the clamping and winding operation. When changing product models, the entire set of clamping fixtures needs to be disassembled and replaced. The model change and debugging process is cumbersome and time-consuming, significantly reducing production and debugging efficiency. The overall versatility of the equipment is poor, making it difficult to adapt to the current demand for multi-specification, small-batch reactor production.

[0005] Existing equipment also has adjustable mold fixing mechanisms. These adjustments usually involve installing multiple evenly distributed grippers on a disc. However, this is not suitable for molds for flat lines because the length and width of flat lines are different. Since these adjustable grippers are evenly distributed around the circumference, they cannot clamp the flat mold. Furthermore, when replacing an existing mold, the mold itself must be disassembled and a new mold must be installed. The purpose of gripper adjustment is to adapt to the dimensions of the mold's own fixing shaft.

[0006] Based on this, the present invention provides a winding device for reactor production to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a winding device for reactor production. The present invention has a novel structure and ingenious design, and effectively solves the technical problem that flat wires are prone to twisting around their own axis during the winding process.

[0008] A winding device for reactor production includes a reactor winding machine, on which a mold fixing mechanism and a wire laying mechanism are installed. A fixing plate is fixedly connected to one side of the reactor winding machine, and multiple horizontal plates are fixedly connected to one side of the fixing plate.

Laser contour sensors are provided on both sides of the fixing seat. A half gear is fixedly connected to the bottom of the second wire laying mechanism, and the half gear meshes with a drive gear. The drive gear is connected to a drive motor.

[0009] Preferably, connecting seats are fixedly connected to both sides of the fixed base, and connecting frames are fixedly connected to one side of both connecting seats, with the laser contour sensor mounted on the connecting frames.

[0010] Preferably, the second conductor mechanism includes a bottom shell, with a double lead screw rotatably connected to the inner side of the bottom shell. Two movable seats are threadedly connected to the double lead screw, and an L-shaped movable plate is fixedly connected to each of the two movable seats.

[0011] Preferably, the top of each of the two L-shaped movable plates is threaded with a threaded rod, the bottom of each of the two threaded rods is rotatably connected to a lifting seat, the two lifting seats are rotatably connected to a movable baffle, and an inner disc spring is provided on the inner side of the lifting seat.

[0012] Preferably, a fixed guide roller assembly is fixedly connected to the inner side of each of the two L-shaped movable plates, and a movable guide roller assembly is fitted onto the fixed guide roller assembly.

[0013] Preferably, both L-shaped movable plates are provided with sliding holes, and inner and outer fan-shaped grooves are provided in the sliding holes. A pull rod that is slidably connected to the movable guide roller assembly is rotatably connected in the sliding holes, and a clamping plate that cooperates with the inner and outer fan-shaped grooves is fixedly connected to the surface of the pull rod.

[0014] Preferably, a U-shaped seat is installed on the wiring mechanism, and a movable seat is rotatably connected to the inner side of the U-shaped seat. A first wire mechanism is fixedly connected to the movable seat.

[0015] Preferably, the mold fixing mechanism includes a base, a lead screw is rotatably connected inside the base, a trapezoidal seat is threadedly connected to the lead screw, sliding seats are slidably arranged on both sides of the trapezoidal seat, two connecting rods are rotatably connected to the sliding seats, an inner support seat is rotatably connected to the connecting rods, and the same spring is fixedly connected between the two sliding seats.

[0016] Preferably, a guide wheel mechanism is installed on one side of the cable laying mechanism. The guide wheel mechanism includes a mounting base, a movable plate is rotatably connected to the mounting base, an outer disc spring is sleeved on the outside of the movable plate, and a wire pressure wheel is rotatably connected to one end of the movable plate.

[0017] Preferably, a telescopic rod is fixedly connected to one side of the reactor winding machine, a U-shaped plate is fixedly connected to one end of the telescopic rod, and a pressure plate is fixedly connected to one end of the U-shaped plate.

[0018] The present invention has the following technical effects.

[0019] 1. This invention uses a double lead screw to drive two sets of L-shaped moving plates to move relative to each other. The distance between the fixed conductor roller group and the moving conductor roller group can be flexibly adjusted according to the width and thickness of the flat wire. At the same time, with the help of the threaded rod, lifting seat and movable baffle structure, the equipment can adapt to the guiding requirements of flat wires of different specifications. It can limit the wire in all directions. The drive motor can drive the circular plate and multiple sets of second conductor mechanisms to rotate and fine adjust gradually through the meshing of the drive gear and half gear. With the help of laser contour sensors on both sides to scan the contour posture of the wire in real time, it can correct the slight torsion angle of the wire and avoid problems such as uneven coil width, uneven inter-turn gap and insulation layer compression damage caused by wire torsion. It can effectively ensure the flatness and regularity of the reactor coil winding and improve the insulation performance and operational stability of the product.

[0020] 2. This invention drives the trapezoidal seat to move by rotating the lead screw. Utilizing the sliding engagement between the trapezoidal seat and two sliding seats, the two sets of sliding seats can slide relative to or away from each other. Combined with the connecting rod transmission, the synchronous expansion and contraction of the four inner support seats can be achieved. This allows for the clamping and fixing of reactor winding molds with different inner diameters and specifications. This structure can quickly clamp molds of different specifications without replacing the entire set of fixtures, greatly simplifying the product changeover and debugging process, shortening changeover time, and solving the problems of traditional equipment that can only adapt to a single product, has poor versatility, and is weakly adaptable to small-batch, multi-category production. This significantly improves the applicability and production flexibility of the equipment. Attached Figure Description

Detailed Implementation

[0030] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0031] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] This invention relates to a winding device for reactor production. The device includes a reactor winding machine 1, a mold fixing mechanism 2 fixedly mounted on the main shaft of the reactor winding machine 1, a wire laying mechanism 3 fixedly connected to one side of the reactor winding machine 1, a fixing plate 4 fixedly connected to one side of the fixing plate 4, multiple horizontal plates 5 fixedly connected to one side of the fixing plate 4, a fixing seat 12 slidably connected to the horizontal plate 5, a connecting plate 7 fixedly connected to the bottom of the fixing seat 12, one end of the connecting plate 7 connected to the wire laying mechanism 3, the fixing seat 12 fixedly connected to the connecting plate 7 via a sliding sleeve 11, and the fixing seat 12 sliding on the horizontal plate 5 via the sliding sleeve 11. A circular plate 13 is rotatably connected to the inner side of the fixing seat 12, a second conductor mechanism 10 fixedly mounted on the circular plate 13, and laser contour sensors 16 are provided on both sides of the fixing seat 12.

[0033] The circular plate 13 has an annular groove, and the fixed base 12 has a rotating groove on its opposite inner side. The circular plate 13 is rotatably connected in the two rotating grooves. An arc-shaped block is fixedly connected to the inner side of the two rotating grooves. The arc-shaped block is slidably connected in the annular groove to ensure the rotation stability of the circular plate 13.

[0034] Both sides of the fixed base 12 are fixedly connected to the connecting base 14, and one side of each of the two connecting bases 14 is fixedly connected to the connecting frame 15. The two connecting frames 15 and the opposite side of the two connecting bases 14 are each provided with a laser profile sensor 16. The laser profile sensor 16 is connected to the power supply and the controller.

[0035] In this embodiment, when correcting the twisted flat wire, the fixing plate 4 and the horizontal plate 5 are fixed support structures, which can provide a stable base for the sliding installation of the fixing seat 12. The fixing seat 12 is linked with the wiring mechanism 3 through the connecting plate 7, so that the fixing seat 12 can slide laterally synchronously with the wiring mechanism 3, thereby ensuring that the second conductor mechanism 10 and the wiring operation are moved synchronously, avoiding the problem of pulling and offset caused by the asynchronous wire guiding and wiring action. The circular plate 13 and the fixing seat 12 rotate together, which can rotate the second conductor mechanism 10 for overall rotation and fine adjustment. With the laser contour sensors 16 symmetrically arranged on both sides, the laser contour sensors 16 on both sides are used to ensure that the flat wire placed in the second conductor mechanism 10 does not twist, realize the synchronous detection of the wire on both sides, effectively improve the accuracy of wire twist detection, and capture the small deformation and twist deviation of the wire from all directions.

[0036] As one embodiment, a half gear 17 is fixedly connected to the bottom of the second wire mechanism 10, and a drive gear 18 is rotatably connected to the inner bottom of the fixed base 12 through a mounting bracket. The drive gear 18 is adapted to the half gear 17 and meshes with the half gear 17. A drive motor 19 is fixedly installed on one side of the mounting bracket. The drive motor 19 is a servo geared motor. The drive motor 19 is connected to the power supply and the controller. The output shaft of the drive motor 19 is fixedly connected to the drive gear 18.

[0037] In this embodiment, when the laser profile sensor 16 on each second guide wire mechanism 10 detects a torsion deviation, it corrects the torsion of the flat wire. The drive motor 19 provides the power source and controls the rotation angle and speed of the drive gear 18. By using the meshing transmission between the drive gear 18 and the half gear 17, the continuous rotational motion of the drive gear 18 is converted into the fixed-angle oscillation of the half gear 17, thereby driving the circular plate 13 and the second guide wire mechanism 10 to achieve small-angle rotational fine adjustment. It can match the detection data of the laser profile sensor 16 and correct the small torsion deviation of the wire in real time, solve the problem of autonomous torsion during the flat wire transportation process, and ensure that the wire is transported in a straight posture.

[0038] As an example, the second lead wire mechanism 10 includes a bottom shell 101, and a double lead screw 102 is rotatably connected to the inner side of the bottom shell 101. The threads at both ends of the double lead screw 102 are in opposite directions. Two movable seats 103 are threadedly connected to the double lead screw 102, and an L-shaped movable plate 104 is fixedly connected to each of the two movable seats 103.

[0039] The top of each of the two L-shaped movable plates 104 is threaded with a threaded rod 109, and the bottom of each of the two threaded rods 109 is rotatably connected to a lifting seat 110 that slides up and down. The bottom of the threaded rod 109 is rotatably connected to the lifting seat 110 through a bearing.

[0040] The tops of the two lifting seats 110 are fixedly connected with slide rods, and the tops of the two L-shaped moving plates 104 are provided with guide holes. The two slide rods are slidably connected in the corresponding guide holes to provide stable limit for the sliding of the lifting seats 110. The sliding is not limited to this method, and can also be changed to achieve the lifting seats 110 and L-shaped moving plates 104 through slide rails and slide grooves.

[0041] The inner sides of the two lifting seats 110 are rotatably connected to movable baffles 111 via rotating shafts. The inner side of the lifting seat 110 is fixedly connected to an inner disc spring 112. The other end of the inner disc spring 112 is fixedly connected to the movable baffle 111, and the inner disc spring 112 is sleeved on the outer side of the rotating shaft.

[0042] The upper end of the lifting seat 110 is provided with a stop plate to ensure that the movable baffle 111 is at its maximum upward rotation angle when it is horizontal with the lifting seat 110, which can ensure that the flat wire cannot come out upward when it is placed in the inner limit.

[0043] In this embodiment, when adjusting the equipment according to the specifications of the flat wire, the flat wire is placed into the second conductor mechanism 10 from top to bottom. The flat wire presses the movable baffle 111 to rotate downward. Then the flat wire enters below the movable baffle 111, and the movable baffle 111 is reset under the action of the inner disc spring 112.

[0044] By rotating the double lead screw 102, the two moving seats 103 can be driven to move symmetrically towards or away from each other, thereby adjusting the spacing between the two sets of L-shaped moving plates 104 to adapt to the guiding requirements of flat wires of different widths. The threaded rod 109 can drive the lifting seat 110 to move vertically. With the sliding limit of the slide rod and the guide hole, the lifting seat 110 can be raised and lowered smoothly without deviation, thus achieving the limit adaptation for the thickness direction of the wire.

[0045] The movable baffle 111 can adaptively flip under external pressure, making it easy for the wire to be quickly inserted. At the same time, under the elastic reset action of the inner disc spring 112, it automatically fits the surface of the wire, realizing the limit of the upper surface of the flat wire. It can effectively limit the vertical and horizontal displacement of the wire, and avoid rigid clamping and squeezing to damage the insulation layer of the wire, thus taking into account both guiding accuracy and wire protection effect.

[0046] At this point, the flat wire is restricted in all directions (up, down, left, and right) to prevent it from twisting.

[0047] As an example, a knob is fixedly connected to one end of the double lead screw 102. The knob has anti-slip texture. Two rectangular through holes are opened on the top of the bottom shell 101. The tops of the two movable seats 103 are fixedly connected to the two L-shaped movable plates 104 through connecting blocks. The size of the connecting blocks is adapted to the rectangular through holes. The two connecting blocks are slidably connected in the two rectangular through holes respectively.

[0048] In this embodiment, when adjusting the equipment according to the specifications of the flat wire, the knob with anti-slip texture facilitates manual operation by the staff. The double lead screw 102 can be easily rotated without auxiliary tools. The connecting block slides with the rectangular through hole, which can limit the horizontal movement of the moving seat 103 and prevent the moving seat 103 from rotating with the double lead screw 102. This ensures that the two sets of L-shaped moving plates 104 always remain parallel and open and close, ensuring that the guide structures on both sides are symmetrically aligned, so that the wire is guided in the center and effectively avoids the problem of wire deviation and misalignment.

[0049] As an example, fixed guide roller groups 108 are fixedly connected to the inner sides of the two L-shaped movable plates 104, and movable guide roller groups 113 are fitted on the fixed guide roller groups 108.

[0050] Two L-shaped movable plates 104 are provided with sliding holes 105 on opposite sides. The inner side of the sliding hole 105 is provided with an inner fan-shaped groove 106 and an outer fan-shaped groove 107. The inner side of the sliding hole 105 is provided with a connecting groove 116. The inner fan-shaped groove 106 and the outer fan-shaped groove 107 are connected through the connecting groove 116. A pull rod 114 is slidably connected in the sliding hole 105. One end of the pull rod 114 is rotatably connected to a moving guide roller assembly 113. One end of the pull rod 114 is rotatably connected to the moving guide roller assembly 113 through a bearing. A limit rod is fixedly connected to one side of the moving guide roller assembly 113. A limit hole is provided on one side of the L-shaped movable plate 104. The limit rod is slidably connected in the limit hole.

[0051] A locking plate 115 is fixedly connected to the surface of the pull rod 114. The locking plate 115 can be locked in the inner sector groove 106 or the outer sector groove 107. The locking plate 115 can rotate in the inner sector groove 106 or the outer sector groove 107 to achieve limiting and unlocking.

[0052] There are multiple sets of movable guide rollers 113, and all sets of movable guide rollers 113 have the same structure.

[0053] There are multiple horizontal plates 5, and the connection structure of the multiple horizontal plates 5 is the same. Rectangular grooves 117 are opened on the opposite sides of the two L-shaped movable plates 104.

[0054] In this embodiment, when adjusting the equipment according to the specifications of the flat wire, the fixed conductor roller group 108 and the movable conductor roller group 113 cooperate with each other to form a double-sided roller clamping and guiding structure, which can guide the wire to fit together on both sides and reduce the frictional resistance of the wire conveying.

[0055] By rotating and pushing or pulling the lever 114, the operator causes the lever 114 to move the clamping plate 115 away from the inner sector groove 106 or the outer sector groove 107, allowing the lever 114 to slide and adjust within the sliding hole 105. This allows the clamping plate 115 to slide within the connecting groove 116. Depending on the thickness of the wire, the clamping plate 115 is engaged in the appropriate inner sector groove 106 or outer sector groove 107, quickly locking the position of the moving guide roller assembly 113 extending from the rectangular groove 117. This adapts to the guiding requirements of wires of different thicknesses. The sliding cooperation between the limiting rod and the limiting hole restricts the movement trajectory of the moving guide roller assembly 113, ensuring that it is always aligned with the wire and preventing deviation and jamming. The coordinated action of multiple moving guide roller assemblies 113 and fixed guide roller assemblies 108 further enhances the stability and regularity of wire conveying.

[0056] Based on the commonly used dimensions and specifications of flat wires, the inner fan-shaped groove 106 or the outer fan-shaped groove 107 can be designed in multiple ways.

[0057] As an example, the wiring mechanism 3 includes an L-shaped seat 301. One side of the L-shaped seat 301 is fixedly connected to the reactor winding machine 1. The L-shaped seat 301 and the opposite side of the reactor winding machine 1 are rotatably connected to the same threaded post 302. A geared motor is provided inside the reactor winding machine 1. The output shaft of the geared motor is fixedly connected to one end of the threaded post 302. The geared motor is connected to a power supply and a controller. A moving block 303 is threadedly connected to the threaded post 302. The wiring mechanism 3 is prior art and will not be described in detail here.

[0058] The top of the movable block 303 is fixedly connected to a U-shaped seat 8, and the inner side of the U-shaped seat 8 is rotatably connected to a movable seat. The movable seat is rotatably connected to the inner side of the U-shaped seat 8 through a connecting shaft and a bearing. The top of the movable seat is fixedly connected to a first wire guide mechanism 9, which has the same structure as the second wire guide mechanism 10.

[0059] Two elastic components are rotatably connected to the inner bottom of the U-shaped seat 8. The other ends of the two elastic components are rotatably connected to the bottom of the movable seat. The elastic components include a fixed cylinder, and a movable rod is slidably connected inside the fixed cylinder. An end plate is fixedly connected to one end of both the fixed cylinder and the movable rod. The same compression spring is fixedly connected to the opposite surfaces of the two end plates. The compression spring is sleeved on the outside of the fixed cylinder and the movable rod. Both end plates are rotatably connected to the movable seat and the U-shaped seat 8 respectively through hinged seats.

[0060] In this embodiment, when the device is winding the wire, the geared motor drives the threaded column 302 to rotate at a constant speed, which in turn drives the moving block 303 to move horizontally back and forth, realizing automated and uniform wire laying, ensuring that the coil turns are arranged evenly and neatly. The movable seat can rotate adaptively inside the U-shaped seat 8. With the elastic buffering effect of the two sets of elastic components at the bottom, it can adaptively adapt to the angle change of the winding point, so that the first conductor mechanism 9 can change its angle according to the change of the winding point, ensuring that the wire enters the winding mold with the correct posture and the shortest free segment after coming out of the first conductor mechanism 9, effectively solving the problem of wire posture deviation in traditional wire laying structures.

[0061] As one embodiment, the mold fixing mechanism 2 includes a base 201, a lead screw 205 is rotatably connected inside the base 201, a trapezoidal seat 206 is threadedly connected to the lead screw 205, sliding seats 203 are slidably arranged on both sides of the trapezoidal seat 206, two connecting rods 209 are rotatably connected to the sliding seats 203, and an inner support seat 210 is rotatably connected to the connecting rods 209.

[0062] Specifically, the inner side of the seat 201 is provided with a groove 202, and the inner side of the groove 202 is provided with a sliding groove 211. The sliding groove 211 is adapted to the sliding seat 203. Two sliding seats 203 are slidably connected in the sliding groove 211. U-shaped grooves 204 are provided on the opposite sides of the two sliding seats 203. The trapezoidal seat 206 is adapted to the U-shaped grooves 204. The trapezoidal seat 206 is slidably connected in the two U-shaped grooves 204. Two connecting rods 209 are rotatably connected to one side of each of the two sliding seats 203 through a pin.

[0063] In this embodiment, when fixing the reactor winding mold, the lead screw 205 is rotated, which drives the trapezoidal seat 206 to move horizontally. The trapezoidal seat 206 and the two sets of sliding seats 203 are connected by inclined surfaces to transmit the horizontal thrust of the trapezoidal seat 206 into the symmetrical opening and closing motion of the two sets of sliding seats 203. The sliding groove 211 limits and guides the sliding seat 203. Through the hinge transmission of the connecting rod 209, the four inner support seats 210 are driven to expand or contract synchronously, realizing the adaptive inner support clamping and fixing of molds with different inner diameters. Multi-specification mold clamping can be completed without changing the fixture, which greatly improves the equipment versatility and changeover efficiency.

[0064] As one embodiment, the two sliding seats 203 are fixedly connected to the opposite sides of the same spring 207, and there are two springs 207, with the positions of the two springs 207 being symmetrical.

[0065] One end of the lead screw 205 is fixedly connected to a rotating plate 208, and bolts are threaded on the surface of the rotating plate 208. Multiple circumferentially distributed limit holes are opened on the base 201, and the bolts are engaged with the limit holes.

[0066] In this embodiment, when fixing the reactor winding mold, two sets of symmetrically arranged springs 207 can provide continuous elastic preload to the sliding seat 203, so that the sliding seat 203 and the inner support seat 210 always remain in contact and under force, eliminating transmission gaps. The rotating plate 208 allows the operator to manually control the rotation of the lead screw 205. After adjustment, tightening the bolts can achieve mechanical locking between the rotating plate 208 and the lead screw 205, preventing the lead screw 205 from rotating during winding operations and ensuring the stability of equipment operation.

[0067] As an example, a guide wheel mechanism 20 is fixedly connected to one side of the movable block 303 on the cable laying mechanism 3. The guide wheel mechanism 20 includes a mounting base 2001. A fixed rod is fixedly connected to the inner side of the mounting base 2001, and a movable plate 2002 is rotatably connected to the fixed rod. The movable plate 2002 is rotatably connected to the fixed rod through a bearing, and an outer disc spring 2003 is sleeved on the outer side of the fixed rod. One end of the outer disc spring 2003 is fixedly connected to the movable plate 2002, and the other end of the outer disc spring 2003 is fixedly connected to the inner side of the mounting base 2001. A wire pressure wheel 2004 is rotatably connected to one end of the movable plate 2002.

[0068] In this embodiment, when the wire is wound, the outer disc spring 2003 provides an elastic reset driving force for the movable plate 2002, so that the movable plate 2002 can adapt to elastic rotation, driving the end wire pressure roller 2004 to always be in close contact with the wire surface, and to elastically press and guide the wire in real time. This structure can adaptively compensate for the tension changes during the wire conveying process, effectively suppress the wire shaking, jumping and deviation problems, realize the secondary straightening and limiting of the wire, further improve the wire laying accuracy and winding regularity, and assist in completing high-quality winding operations.

[0069] As an example, a telescopic rod 21 is fixedly connected to one side of the reactor winding machine 1, a U-shaped plate 22 is fixedly connected to one end of the telescopic rod 21, and a pressure plate 23 is fixedly connected to one end of the U-shaped plate 22.

[0070] A handle is fixedly connected to the top of the U-shaped plate 22. A limit plate is fixedly connected to one side of the reactor winding machine 1. The inner side of the U-shaped plate 22 overlaps with the surface of the limit plate. A wire feeding frame is provided on one side of the reactor winding machine 1, and a wire feeding roller 6 is placed on the wire feeding frame. The position of the wire feeding roller 6 corresponds to the position of the mold fixing mechanism 2.

[0071] In this embodiment, during the initial and final stages of wire winding, the operator moves the U-shaped plate 22 away from the limiting plate by manipulating the handle. The operator can then extend the telescopic rod 21 to move the U-shaped plate 22 and the end pressure plate 23 downwards, thus assisting in compacting and shaping the wire at the beginning and end of the coil. After the coil is compacted, the pressure plate can be retracted and reset, effectively solving problems such as looseness, protrusion, and warping at the beginning and end of the coil, ensuring that the overall coil is tightly wound and has a neat appearance, and improving the consistency of the reactor's finished product quality.

[0072] Working principle of this invention:

[0073] S1. The operator places the reactor mold to be wound on the mold fixing mechanism 2. By rotating the rotating plate 208, the lead screw 205 is driven to rotate. The lead screw 205 drives the trapezoidal seat 206 to move horizontally. By utilizing the sliding cooperation between the trapezoidal seat 206 and the two sets of sliding seats 203, the two sliding seats 203 are pushed to slide relative to each other or back to back in the sliding groove 211. During the movement of the sliding seats 203, the connecting rod 209 is driven to rotate through the pin shaft, thereby driving the four inner support seats 210 to expand or contract synchronously, adaptively fitting the inner side wall of the mold to be processed, and realizing the inner support clamping and fixing of the mold.

[0074] S2. After the mold is clamped in place, tighten the bolts on the surface of the rotating plate 208 so that the ends of the bolts engage with the limiting holes on the surface of the base 201 to lock the lead screw 205, preventing the mold from loosening or shifting during the winding operation, and completing the quick clamping and fixing of molds of different specifications. Product changeover and debugging can be completed without changing the fixture.

[0075] S3. After the mold is fixed, press the flat wire to press the movable baffle 111 downwards. Under the elastic force of the inner disc spring 112, the movable baffle 111 flips downwards, causing the flat wire to be inserted into the first guide wire mechanism 9 and the second guide wire mechanism 10. One end of the flat wire to be processed is then passed through the guide roller 2004 of the guide roller mechanism 20. According to the width and thickness specifications of the wire, the operator rotates the knob to drive the double lead screw 102 to rotate. The reverse threads at both ends of the double lead screw 102 drive the two moving seats 103 to move relative to each other, simultaneously driving the two sets of L-shaped moving plates 104 to open and close. Adjust the spacing between the corresponding fixed guide roller group 108 and the movable guide roller group 113 so that they fit against the two sides of the wire. The movable guide roller group 113 is locked in place by the push-pull rod 114 and the clamping plate 115 in the inner fan-shaped groove 106 or outer fan-shaped groove 107 at different positions. This locks the position of the movable guide roller group 113, adapting to the guiding requirements of wires of different thicknesses and limiting the wire. At the same time, according to the thickness of the flat wire, the threaded rod 109 is rotated to drive the lifting seat 110 to move up and down, limiting the upper surface of the wire.

[0076] S4. During the formal winding operation, the laser contour sensors 16 on both sides of the multiple fixed seats 12 are continuously powered on and work to scan the contour shape of the wire in real time during the conveying process, dynamically collect whether there is axial torsion of the wire, and transmit the detection signal to the equipment controller. When the sensor detects a slight torsion angle in the wire, the controller starts the drive motor 19 to work. The output shaft of the drive motor 19 drives the active gear 18 to rotate. Through the meshing transmission between the active gear 18 and the half gear 17, the circular plate 13 and the overall second guide wire mechanism 10 above it are driven to finely adjust the rotation angle. Through multiple sets of second guide wire mechanisms 10, the axial torsion deviation of the wire is gradually corrected. At the same time, the fixed seat 12 can slide synchronously with the wire laying mechanism 3 through the connecting plate 7, and cooperate with the horizontal plate 5 and the sliding sleeve 11 to achieve follow-up guidance, ensuring that the correction action and the wire laying action are synchronized and there is no relative displacement error.

[0077] S5. After the wire posture correction is completed, the geared motor built into the reactor winding machine 1 drives the threaded column 302 to rotate at a constant speed, which drives the moving block 303 to move horizontally back and forth along the threaded column 302, realizing automated uniform speed wire laying operation. The two sets of elastic components inside the U-shaped seat 8 at the top of the moving block 303 form elastic buffer support for the movable seat and the first conductor mechanism 9, so that the first conductor mechanism 9 can change its angle according to the change of the winding point, keeping the wire in the correct posture and with the shortest free section after it comes out of the first conductor mechanism 9 and enters the winding mold. At the same time, the guide wheel mechanism 20 on one side of the moving block 303 works synchronously, and the outer disc spring 2003 drives the movable plate 2002 to rotate adaptively, which drives the conductor pressure roller 2004 to always elastically fit the wire surface, and perform secondary pressing and guiding on the wire. Under the multi-level guiding, buffering and limiting synergistic action of the first conductor mechanism 9, the second conductor mechanism 10 and the guide wheel mechanism 20, the wire is evenly wound on the outside of the fixed mold in a stable, straight and twist-free state, completing the main winding process of the reactor coil.

[0078] S6. During the initial and final stages of wire winding, the operator can extend the telescopic rod 21 to move the U-shaped plate 22 and the end pressure plate 23 downwards, assisting in compacting and shaping the wire at the beginning and end of the coil. After the winding operation of a single reactor is completed, the equipment stops and resets. The locking bolts of the mold fixing mechanism 2 are loosened, and the screw 205 is rotated in the opposite direction to retract the inner support seat 210. The completed reactor coil mold can then be quickly removed, and the next specification mold can be directly replaced. The above process can be repeated for continuous production.
