Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, specifically to a high-frequency transformer winding uniform arrangement winding equipment. Background Technology

[0002] High-frequency transformers are core electromagnetic components in switching power supplies, industrial electrical control systems, and new energy electronic systems. The quality of the interlayer arrangement of the windings directly determines the leakage inductance, distributed capacitance, and insulation withstand voltage performance of the product. High-frequency transformer winding interlayer winding equipment is the core equipment for the mass production of this type of component. It is widely used in the field of electronic component manufacturing to complete the multi-layer dense winding of enameled wire on the transformer frame, and has high requirements for winding accuracy, wire uniformity, and production stability.

[0003] Existing high-frequency transformer winding equipment typically uses a rotating spindle to drive the transformer bobbin to rotate, and an axial reciprocating wire laying mechanism to guide the enameled wire to achieve layer-by-layer winding of the enameled wire on the bobbin.

[0004] However, the existing equipment has a fixed wire entry height for the enameled wire, which cannot dynamically adjust the winding entry angle as the outer diameter of the winding increases. As the number of winding layers increases, the entry angle of the outer enameled wire continues to shift, which can easily lead to uneven outer layer turn spacing, wire overlap and jumper, and scratches on the enameled wire insulation layer. It is difficult to ensure the uniformity of the wiring and the consistency of electromagnetic performance of the entire winding. Summary of the Invention

[0005] The purpose of this invention is to provide a winding device for uniformly arranging winding layers in a high-frequency transformer, which aims to improve the problem in the prior art where the height of the enameled wire entry is fixed, making it difficult to dynamically adjust the winding entry angle as the outer diameter of the winding increases.

[0006] The objective of this invention is achieved through the following technical solution: a high-frequency transformer winding uniformly arranged winding device, including a working box, a control console is provided on the top of the working box, a winding mechanism and a wire output mechanism are provided inside the working box, an enameled wire is provided in the wire output mechanism, a transformer skeleton to be wound is provided on the winding mechanism, and a fine-tuning mechanism is provided inside the working box. The fine-tuning mechanism includes a cable guide plate fixedly connected to the inner wall of the work box at the top.

A heating resistor is installed inside the protective shell and is connected in parallel with a photoresistor via a wire. A heat-conducting plate is installed outside the protective shell, and a fixing sleeve is fixedly connected to the top of the heat-conducting plate. A paraffin block is installed inside the fixing sleeve. A top shaft is also slidably connected inside the fixing sleeve. A connecting rod is fixedly connected to the top of the top shaft. A lifting roller is slidably connected vertically to the inner side wall of the working box, and an auxiliary ring is fixedly connected to the outer side of the lifting roller. The outer side of the auxiliary ring is connected to the other end of the connecting rod. As a further description of the above technical solution: The winding mechanism includes a main shaft rotatably connected to the inside of the working box, a motor is fixedly installed on the outside of the working box, the output end of the motor is fixedly connected to the main shaft, a transformer frame is sleeved on the outside of the main shaft, a worm is also installed on the outside of the main shaft, a turbine is rotatably connected to the inside of the working box and the outside of the turbine meshes with the outside of the worm, heart-shaped cams are fixedly connected to both sides of the turbine, two telescopic cylinders are fixedly connected to the inside of the working box and pressure blocks are fixedly connected to the telescopic ends of the telescopic cylinders, two pressure rods are fixedly connected to the front end of the pressure blocks and the other ends of the two pressure rods respectively abut against the outer slides of the two heart-shaped cams; As a further description of the above technical solution: The winding mechanism also includes a swing rod rotatably connected to the bottom of the working box at one end, a drive rod fixedly connected between the two pressure rods and the outer side of the drive rod slidably connected inside the axial through groove of the swing rod, and a fastening ring rotatably connected to the other end of the swing rod, with counterweights provided at both ends of the fastening ring. As a further description of the above technical solution: The enameled wire passes through the fastening ring, and friction strips are distributed circumferentially on the inner side of the fastening ring to allow the enameled wire to move only along the axial direction and restrict the rotation of the enameled wire. As a further description of the above technical solution: The wire output mechanism includes a wire output roller, a main adjusting roller and a fixed angle roller arranged sequentially along the direction of the enameled wire. The wire output roller is rotatably connected to the inside of the working box and a motor is provided at its end. The two ends of the fixed angle roller are fixedly connected to the inner walls of the two sides of the working box. The outer sides of the fixed angle roller and the outer sides of the main adjusting roller are axially slidably connected to a wire ring and the enameled wire slides in the annular groove inside the wire ring. As a further description of the above technical solution: Both ends of the main adjusting roller are fixedly connected to sliders, and both sides of the working box are fixedly connected to two slide rods. The slider is slidably connected to the outside of the two slide rods. Two compression springs are provided between the top of the slider and the inner wall of the working box, and a constant force spring is provided between the bottom of the slider and the inner wall of the working box. As a further description of the above technical solution: Assuming that friction has little effect on the force relationship of the main adjusting roller, the elastic force of the constant force spring is... The elastic force of the compression spring Gravity of the main adjusting roller Tension of enameled wire The relationship is:

[0007] The gravity of the main adjusting roller The elastic force of the constant force spring For a constant value, when the tension of the enameled wire... When the temperature decreases, the main adjusting roller presses down, causing the spring force to decrease. While reducing the size, the tension of the enameled wire increases. This achieves a state of equilibrium.

[0008] Compared with the prior art, the advantages of the present invention are as follows: 1. A laser probe continuously emits parallel detection light towards the opposite photosensitive plate. As the outer diameter of the winding increases, the incident light is gradually blocked, causing the resistance of the photoresistor inside the photosensitive plate to increase synchronously with the decrease in light intensity. This changes the current distribution ratio of the parallel circuit, causing the current flowing through the heating resistor to increase accordingly. The heat is conducted through the protective shell and heat-conducting plate to the inside of the fixed sleeve, causing the paraffin block to expand upward and push out of the top shaft. The connecting rod synchronously raises the wiring height of the lifting roller, realizing dynamic correction of the wiring height and cutting angle. This allows for real-time adaptation to the increase in the outer diameter of the winding, ensuring uniform and tight wiring across all layers, reducing scratches on the enameled wire insulation layer, and improving the consistency of the winding's electromagnetic performance.

[0009] 2. The enameled wire is uniformly output from the output roller driven by a second motor. The wire passes sequentially through the guide rings on the main adjusting roller and the fixed angle roller, completing the wire guidance. A stable mechanical balance is achieved by the main adjusting roller supported by a compression spring, a constant force spring, and a slider, allowing for a wide range of coarse adjustments to the wire tension. Large tension fluctuations are offset by adjusting the wire path length through lifting and lowering. Simultaneously, the thermal expansion of paraffin wax drives the top shaft to raise the lifting roller, correcting the winding entry angle while simultaneously fine-tuning the wire length, providing precise tension compensation. This achieves the beneficial effect of constant tension winding of the enameled wire through a two-stage linkage. The two stages work together to cover tension fluctuations throughout the entire winding process, preventing loose stacking or excessive tension deformation of the wire, ensuring uniform winding pitch and a compact and stable structure.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 10The diagram shows an embodiment of a high-frequency transformer winding uniform arrangement winding device provided by the present invention. The device includes a work box 1, which serves as the external support shell of the device, housing all internal mechanisms and providing a closed and stable winding operation space, as well as an installation reference for each component. A control console 2 is located on the top of the work box 1, enabling human-machine interaction for inputting winding parameters, controlling the start and stop of the device, and integrating a built-in power supply to power the electrical control circuit. Inside the work box 1 are a winding mechanism 3 and a lead-out mechanism 5. The lead-out mechanism 5 contains enameled wire 6, which is the conductive substrate of the high-frequency transformer winding. The wire is wound around the outside of the transformer frame 4 to form a complete winding, undertaking the function of electromagnetic energy transmission. The winding mechanism 3 has the transformer frame 4 to be wound. The transformer frame 4 serves as the support base for the winding, providing a reference support surface for the winding of the enameled wire 6, and defining the basic shape, size, and winding range of the winding. The work box 1 contains a fine-tuning mechanism. Organization 7.

[0013] The winding mechanism 3 includes a main shaft 301 rotatably connected to the inside of the work box 1. The main shaft 301 carries and fixes the transformer bobbin 4, and outputs rotational motion to drive the bobbin to rotate synchronously, providing the power basis for the circumferential winding of the enameled wire 6. A motor 302 is also fixedly installed on the outside of the work box 1. The motor 302 provides a stable rotational driving force to the main shaft 301, regulates the winding speed, and ensures that the linear speed of the bobbin rotation is uniform. The output end of the motor 302 is fixedly connected to the main shaft 301. The transformer bobbin 4 is sleeved on the outside of the main shaft 301. A worm gear 303 is also installed on the outside of the main shaft 301. The worm gear 303 rotates synchronously with the main shaft 301, transmits rotational power, realizes the deceleration and reversal of power, and provides synchronous power input for the wire laying operation. The inner side of the working box 1 is rotatably connected to a turbine 304, and the outer side of the turbine 304 meshes with the outer side of the worm 303. The turbine 304 and the worm 303 work together to complete the speed reduction transmission, amplify the output torque, drive the heart-shaped cam 305 to rotate synchronously, and match the motion rhythm of winding and laying.

[0014] Heart-shaped cams 305 are fixedly connected to both sides of the turbine 304. These cams convert circular rotation into axial reciprocating linear motion of the pressure rod 308 via their own contour trajectory, providing the motion pattern for the cable routing reciprocating motion. Two telescopic cylinders 306 are fixedly connected to the inner side of the work box 1, and pressure blocks 307 are fixedly connected to the telescopic ends of the cylinders 306. The telescopic cylinders 306 provide guidance for the telescopic motion of the pressure blocks 307, constraining the direction of movement of the pressure blocks 307 and ensuring the straightness and stability of the reciprocating motion of the pressure rod 308. The pressure blocks 307 connect the telescopic cylinders 306 and the pressure rods 308, transmitting reciprocating driving force and ensuring synchronous movement of the two pressure rods 308, avoiding misalignment or deviation. The front end of the pressure block 307 is fixedly connected to two pressure rods 308, and the other ends of the two pressure rods 308 respectively abut against the outer slide rails of the two heart-shaped cams 305. The pressure rods 308 abut against the outer slide rails of the heart-shaped cams 305 and move axially back and forth as the cam profile changes, converting the cam curve motion into linear drive displacement.

[0015] The winding mechanism 3 also includes a swing rod 309 rotatably connected at one end to the bottom of the work box 1. The swing rod 309 reciprocates around the bottom fulcrum, converting the linear displacement of the drive rod 310 into the axial reciprocating displacement of the top end, thus realizing the reciprocating motion of the wire. The drive rod 310 is fixedly connected between the two pressure rods 308, and the outer side of the drive rod 310 is slidably connected inside the axial through groove of the swing rod 309. The drive rod 310 reciprocates synchronously with the pressure rods 308, embedding itself into the through groove of the swing rod 309 to transmit power, driving the swing rod 309 to complete the reciprocating swing action. The other end of the swing rod 309 is rotatably connected to a fastening ring 311, and both ends of the fastening ring 311 are provided with counterweights 312. The fastening ring 311 passes through and constrains the enameled wire 6, and moves axially synchronously with the swing rod 309, guiding the enameled wire 6 to be evenly distributed along the axis of the frame and controlling the winding turn pitch. The counterweights 312 are symmetrically arranged at both ends of the fastening ring 311 to balance the weight on both sides of the fastening ring 311, suppress the shaking during the swing process, and improve the stability of the wire laying movement. The enameled wire 6 passes through the fastening ring 311, and friction strips are distributed circumferentially on the inner side of the fastening ring 311 to allow the enameled wire 6 to move only along the axis and restrict the rotation of the enameled wire 6. The friction strips can prevent the wire from twisting and causing misalignment of the wire laying.

[0016] The wire feeding mechanism 5 includes a wire feeding roller 501, a main adjusting roller 503, and a fixed-angle roller 508 arranged sequentially along the direction of the enameled wire 6. The wire feeding roller 501 carries the coiled enameled wire 6 and rotates at a constant speed under power drive, continuously feeding the wire outward to provide a stable wire supply for the winding operation. The main adjusting roller 503 changes the length of the wire path of the enameled wire 6 by its own vertical lifting, adjusting the tension of the enameled wire 6 over a wide range to achieve coarse tension compensation. The fixed-angle roller 508 fixes the wire feeding direction and reference angle of the enameled wire 6, providing a stable wire entry reference for the winding end and ensuring the consistency of the wire feeding direction. The wire feeding roller 501 is rotatably connected to the inside of the working box 1, and a second motor 502 is provided at its end. The second motor 502 provides rotational driving force to the wire feeding roller 501, regulates the wire feeding speed, and makes the wire feeding rhythm precisely matched with the winding speed. The two ends of the fixed angle roller 508 are fixedly connected to the inner walls of both sides of the working box 1. The outer side of the fixed angle roller 508 and the outer side of the main adjusting roller 503 are axially slidably connected to the guide ring 509, and the enameled wire 6 slides in the annular groove inside the guide ring 509. The guide ring 509 can slide along the roller body axially, constrain the radial position of the enameled wire 6, guide the wire to move along the roller body axially, and prevent the wire from deviating and derailing.

[0017] Both ends of the main adjusting roller 503 are fixedly connected to sliders 504. The sliders 504 are fixed to both ends of the main adjusting roller 503 and slide along the slide rods 505, driving the main adjusting roller 503 to rise and fall, providing a displacement carrier for tension adjustment. Two slide rods 505 are fixedly connected to both sides of the working box 1. The slide rods 505 provide vertical movement guidance for the sliders 504, constraining the movement trajectory of the sliders 504 and ensuring smooth and unbiased movement of the main adjusting roller 503 during lifting and lowering. The sliders 504 are slidably connected to the outside of the two slide rods 505. Two compression springs 506 are installed between the top of the slider 504 and the inner wall of the working box 1. The compression springs 506 apply downward elastic pressure to the sliders 504, forming a mechanical balance system with gravity and a constant force spring 507, participating in the force feedback for tension adjustment. Under the premise that friction has little impact on the force relationship of the main adjusting roller 503, the elastic force of the constant force spring 507... The elasticity of spring 506 The gravity of the main adjusting roller 503 and the tension of the enameled wire 6 The relationship is:

[0018] The gravity of the main adjusting roller 503 The elasticity of constant force spring 507 For a constant value, when the tension of the enameled wire 6 When the temperature decreases, the main adjusting roller 503 presses down, causing the spring force of the compression spring 506 to decrease. While reducing the size, the tension of the enameled wire 6 is increased. This achieves a state of equilibrium.

[0019] The fine-tuning mechanism 7 includes a guide plate 701 fixedly connected to the inner wall of the work box 1 at the top. The guide plate 701 serves as the mounting carrier for the fine-tuning mechanism 7, fixing various detection and actuation elements and providing a precise installation positioning reference for each component. A retaining ring 702 is provided at the bottom of the guide plate 701 and engages with both ends of the winding portion of the transformer bobbin 4. The retaining ring 702 defines the axial winding boundary of the winding and prevents the enameled wire 6 from winding out of the effective area of ​​the bobbin. A laser probe 703 is provided on the outside of one of the guide plates 701. The laser probe 703 emits parallel detection light, providing a stable light source signal for the detection of the winding outer diameter, realizing non-contact detection of the winding outer diameter. A photosensitive plate 704 is provided at the opposite position of the other guide plate 701. The photosensitive plate 704 carries an internal photoresistor and receives the light emitted by the laser probe 703, providing a receiving carrier for changes in light intensity. Furthermore, a photoresistor is internally installed in the photosensitive plate 704. Based on the photoconductivity effect, the photoresistor changes its resistance according to the intensity of the received light, converting the light signal into a changing electrical signal, providing a signal basis for subsequent adjustments. The control console 2 has a built-in power supply with a wire 705 at its output. The built-in power supply provides stable power to the parallel circuit composed of the photoresistor and the heating resistor 707, ensuring continuous and stable operation of the detection and execution circuits. The wire 705 connects the built-in power supply, the photoresistor, and the heating resistor 707, transmitting electrical energy and forming a complete power supply and signal circuit. The wire 705 is electrically connected to the photoresistor, and a heating element is also internally installed in the wiring board 701, connected in parallel with the photoresistor via the wire 705.

[0020] The heating element includes a protective shell 706 fixedly connected inside the through-plate 701. The protective shell 706 encapsulates a heating resistor 707, preventing heat from spreading outwards and protecting the internal heating element while improving heat conduction efficiency. The heating resistor 707 is housed inside the protective shell 706. When energized, the heating resistor 707 generates heat, which can be adjusted according to the current flowing through it, providing a controllable heat source for the thermal expansion of the paraffin. The heating resistor 707 is connected in parallel with a photoresistor via a wire 705. A heat-conducting plate 708 is located outside the protective shell 706, and a fixing sleeve 709 is fixedly connected to the top of the heat-conducting plate 708. The heat-conducting plate 708 evenly conducts the heat generated by the heating resistor 707, smoothly transferring the heat to the fixing sleeve 709, ensuring uniform heating of the internal paraffin. The fixing sleeve 709 accommodates the paraffin block 710 and the top shaft 711, providing a sealed chamber and precise movement guidance for the thermal expansion and contraction of the paraffin and the sliding of the top shaft 711. The fixed sleeve 709 has a paraffin block 710 inside. The paraffin block 710 uses the physical property of thermal expansion and contraction to change its volume with temperature changes, converting heat energy into mechanical thrust that drives the top shaft 711 to move.

[0021] Inside the fixed sleeve 709, a top shaft 711 is slidably connected. Under the thrust of the expanding paraffin wax, the top shaft 711 slides along the fixed sleeve 709, converting the volume expansion of the paraffin wax into linear displacement, driving the lifting component. A connecting rod 712 is fixedly connected to the top of the top shaft 711, connecting the top shaft 711 to the auxiliary ring 714 of the lifting roller 713, transmitting lifting power and driving the lifting roller 713 to synchronously complete the lifting and lowering action. The lifting roller 713 is slidably connected vertically to the inner wall of the working box 1. The lifting roller 713 changes its own height to alter the routing height and winding angle of the enameled wire 6, synchronously fine-tuning the routing length to achieve precise compensation of winding posture and tension. Furthermore, an auxiliary ring 714 is fixedly connected to the outer side of the lifting roller 713, uniformly transmitting the lifting force to the lifting roller 713, ensuring smooth and synchronous lifting of the roller. The outer side of the auxiliary ring 714 is connected to the other end of the connecting rod 712, thereby transmitting the vertical movement of the connecting rod 712 to the entire lifting roller 713.

[0022] Working principle: Before starting the equipment, the operator first sets the transformer bobbin 4 to be wound on the outside of the main shaft 301 of the winding mechanism 3, and then installs the coiled enameled wire 6 at the output roller 501 of the output mechanism 5. After the end of the enameled wire 6 is led out from the output roller 501, it passes through the conductor ring 509 outside the main adjusting roller 503 and the conductor ring 509 outside the fixed angle roller 508 in sequence, and then passes into the fastening ring 311 inside the winding mechanism 3. Finally, the end of the enameled wire 6 is fixed at the starting winding position of the transformer bobbin 4. Then, the operator operates the control console 2 on the top of the work box 1 to input parameters such as the target number of turns and the winding speed to complete the initial wiring and parameter setting of the equipment.

[0023] After pressing the start button, motor 502 of the wire feeding mechanism 5 starts running first, driving the wire feeding roller 501 to rotate at a constant speed and continuously feeding the enameled wire 6 outward. The enameled wire 6 passes sequentially through the guide ring 509 of the main adjusting roller 503 and the fixed angle roller 508. The guide ring 509 slides synchronously along the roller surface with the axial displacement of the enameled wire 6, guiding the enameled wire 6 to maintain a stable wire feeding direction. When the tension of the enameled wire 6 decreases during the feeding process, the sliders 504 at both ends of the main adjusting roller 503, under the combined action of the elastic force of the compression spring 506 and the weight of the main adjusting roller 503 itself, move along the axis of the slide rod 505. As the slider 504 slides downwards, the compression of the spring 506 gradually decreases, and the elastic force generated by the spring 506 decreases synchronously. At the same time, the constant force spring 507 at the bottom of the slider 504 is further compressed until the mechanical relationship reaches a new equilibrium. The downward movement of the main adjusting roller 503 will lengthen the overall path length of the enameled wire 6. When the tension of the enameled wire 6 increases, the main adjusting roller 503 is lifted upwards by the enameled wire 6, and the compression of the spring 506 increases accordingly. The constant force spring 507 rebounds and releases its deformation synchronously. As the main adjusting roller 503 moves upwards, the path length of the enameled wire 6 is shortened.

[0024] The motor 302 of the winding mechanism 3 starts synchronously with the output mechanism 5. The motor 302 drives the main shaft 301 to rotate at a constant speed around its own axis. The transformer frame 4, which is fixed on the outside of the main shaft 301, rotates synchronously with the main shaft 301, winding the continuously supplied enameled wire 6 layer by layer around the outside of the winding area of ​​the frame. While the main shaft 301 rotates, the worm 303 fixed on its outside rotates synchronously with the main shaft 301. The gear teeth of the worm 303 drive the worm wheel that meshes with it to rotate around its own central axis. The two heart-shaped cams 305 fixed on both sides of the worm wheel rotate synchronously with the worm wheel.

[0025] During the rotation of the heart-shaped cam 305, the profile of its outer edge slideway continuously changes. The two pressure rods 308, which abut against the slideway, move in a straight line along the axis of the slideway as the profile changes. The pressure rods 308 drive the pressure block 307 fixed at the front end to move in a synchronous reciprocating extension and retraction along the axis of the telescopic cylinder 306. The drive rod 310 fixed between the two pressure rods 308 moves in a synchronous reciprocating translation with the pressure rods 308. The rod body of the drive rod 310 is embedded in the axial through groove of the swing rod 309, which drives the swing rod 309 to swing left and right around the rotation fulcrum at its bottom.

[0026] During the reciprocating swing of the swing rod 309, the fastening ring 311 at its top moves back and forth at a constant speed along the axial direction of the transformer frame 4 with the swing motion. The enameled wire 6 passing through the inside of the fastening ring 311 is driven by the fastening ring 311 to move synchronously along the axial direction of the frame. With the continuous rotation of the transformer frame 4, the enameled wire 6 is arranged in circles and stacked layer by layer at a uniform interval and wound around the winding area of ​​the transformer frame 4. The friction strips distributed circumferentially on the inner side of the fastening ring 311 are in continuous contact with the outer surface of the enameled wire 6, restricting the circumferential rotation of the enameled wire 6 along its own axis and only allowing the enameled wire 6 to be conveyed forward along the axial direction.

[0027] During the continuous winding process, the laser probe 703 of the fine-tuning mechanism 7 continuously emits parallel detection light to the photosensitive plate 704 on the opposite side. As the number of layers of enameled wire 6 on the transformer frame 4 gradually increases, the overall outer diameter of the winding continuously increases, and the side wall of the winding gradually blocks the light emitted by the laser probe 703, causing the light intensity received by the surface of the photosensitive plate 704 to continuously weaken. The resistance value of the photoresistor inside the photosensitive plate 704 changes accordingly with the decrease in light intensity.

[0028] The built-in power supply inside the console 2 continuously supplies power to the parallel circuit composed of the photoresistor and the heating resistor 707 through the wire 705. When the resistance of the photoresistor changes, the current distribution inside the parallel circuit changes synchronously, and the current flowing through the heating resistor 707 increases or decreases accordingly, causing the heat generated by the heating resistor 707 to fluctuate synchronously. When the light intensity decreases, the resistance of the photoresistor increases, which in turn increases the current flowing through the heating resistor 707, and the heat of the heating resistor 707 rises.

[0029] The heat generated by the heating resistor 707 is transferred through the protective shell 706 to the outer heat-conducting plate 708. The heat-conducting plate 708 evenly conducts the heat to the interior of the upper fixed sleeve 709, causing the temperature of the paraffin block 710 inside the fixed sleeve 709 to rise and undergo thermal expansion. The increased volume of the paraffin block 710 due to thermal expansion pushes the top shaft 711 to slide upwards along the inner wall of the fixed sleeve 709. The connecting rod 712 fixed at the top of the top shaft 711 rises synchronously with the top shaft 711. The other end of the connecting rod 712... The lifting roller 713 connected to the end slides upward along the vertical guide structure on the inner side wall of the working box 1. The auxiliary ring 714 on the outer side of the lifting roller 713 rises synchronously with the lifting roller 713, changing the routing height and cutting angle of the enameled wire 6 when it passes through the lifting roller 713. This dynamically adapts to the continuous increase in the outer diameter of the winding, corrects the winding cutting angle in real time, ensures the uniformity of the wiring and the tightness of the winding from the bottom layer to the outer layer, reduces the scratching of the insulation layer of the enameled wire 6, and ultimately improves the winding layout accuracy and the consistency of electromagnetic performance.

[0030] When the counting module of the equipment detects that the number of winding turns has reached the target value preset by the control panel 2, motor 1 302 and motor 2 502 stop running synchronously, the main shaft 301 and the lead roller 501 stop rotating, the heart-shaped cam 305 stops rotating and returns to its initial position, the swing rod 309 drives the fastening ring 311 to reset to the starting end of the winding, the heating resistor 707 of the fine adjustment mechanism 7 stops heating, the paraffin block 710 inside the fixed sleeve 709 gradually shrinks and solidifies as the temperature decreases, the top shaft 711 drives the lifting roller 713 to fall back to the initial height under the action of gravity, the operator cuts the end of the enameled wire 6, loosens the fixing structure on the main shaft 301, and removes the completed transformer frame 4, thus completing the winding operation of a single high-frequency transformer winding.
