An automatic coil winding device for manufacturing electronic transformers

Abstract

This invention discloses an automatic coil winding device for electronic transformer manufacturing, belonging to the field of electronic transformer technology. It includes a main body with a rotating assembly, a clamping assembly, a wire positioning assembly, and an insulation layer positioning assembly. During the winding process, the device, through slots and spring hinges, restricts the movement trajectory of the insulation material, ensuring it remains on the outside of the coil bobbin wire, thus guaranteeing winding quality. Furthermore, the winding process intermittently compresses the outermost insulation material wound around the coil bobbin, resulting in a tighter connection between the insulation material and the wire. This compression effectively reduces air bubbles and improves winding quality.

Description

Technical Field

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

[0002] An electronic transformer is a device that uses high-frequency switching technology and electronic components to achieve voltage transformation, isolation, and power transfer. It is one of the core achievements of modern electronic technology. The coil of an electronic transformer is one of its core components, and its design and winding process directly determine the transformer's performance (such as efficiency, temperature rise, leakage inductance, and distributed capacitance). Currently, it is mainly completed by an automatic winding machine. First, the bobbin is fixed on the automatic winding machine, and one end of the wire is fixed on the bobbin. The automatic winding machine is started, and the wire is wound around the bobbin. At the end of each layer, an insulating layer material (such as insulating tape) is wrapped around the outside of the wire until the number of wire layers on the bobbin meets the working requirements. Finally, the coil winding operation is completed. The overall operation has a high degree of automation and intelligence.

[0003] In actual winding processes, when winding insulating tape, the tape roll is installed on an automatic winding machine using the same method. During the winding process, the tape can be automatically wound around the conductor. However, unlike the conductor, because the tape is wider, it is already wrapped around the conductor once only a certain width has been wound. Therefore, the machine needs to be stopped to cut the tape before the conductor winding operation can continue. As a result, in subsequent winding processes, one end of the tape wrapped around the conductor lacks a fixing device. During subsequent winding, the tape end will disconnect from the coil frame, which may cause wrinkles at the tape end during the subsequent conductor winding process, thus affecting the subsequent winding work. Furthermore, there is no tape compression device during the winding process; the fixation relies solely on the tape's own adhesiveness, resulting in a generally poor fixing effect and a high possibility of air bubbles, further reducing the winding effect. Therefore, an automatic coil winding device for electronic transformer manufacturing is provided. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic coil winding device for the production and manufacturing of electronic transformers.

[0005] The present invention adopts the following technical solution:

[0006] An automatic coil winding device for manufacturing electronic transformers includes a main body, a rotating assembly, a clamping assembly, a wire positioning assembly, and an insulation layer positioning assembly. The insulation layer positioning assembly includes a pressing assembly. The pressing assembly includes a control hydraulic cylinder fixedly connected to the insulation layer positioning assembly. An arc-shaped box is fixedly connected to the output end of the control hydraulic cylinder. The arc-shaped box has two through slots, which together slidably connect to a movable frame. The movable frame is connected to multiple round rods via a connecting assembly. A rotating rod is rotatably connected through the arc-shaped box. A first gear is fixedly connected to the rotating rod. A movable ring is slidably connected to the main body. The movable ring and the rotating assembly are rotatably connected. A first rack is fixedly connected to the movable ring, and the first rack meshes with the first gear. The rotating rod has an annular groove, within which a sliding rod is slidably connected. A sleeve is fixedly connected to the sliding rod, and the sleeve is fixedly connected to the movable frame via a first connecting rod.

[0007] Preferably, the connecting assembly includes two movable blocks slidably connected to the movable frame, a first spring fixedly connected between the two movable blocks and the movable frame, a square rod fixedly connected to each movable block, a square cylinder slidably connected to each square rod, a second spring fixedly connected between the square cylinder and the square rod, a pressing frame fixedly connected to the square cylinder, and a plurality of pressing rods rotatably connected through the pressing frame, with the round rod and the pressing rods fixedly connected.

[0008] Preferably, the arc-shaped box is equipped with a control component for controlling the movement of the moving block. The control component includes a second connecting rod fixedly installed on the side wall of the moving block, a rotating rod fixedly connected to a rotating disk, and a plurality of support rods fixedly connected to the rotating disk circumferentially.

[0009] Preferably, the square tube is fixedly connected to a third connecting rod, and the movable frame is fixedly connected to an inclined plate.

[0010] Preferably, the second connecting rod is fixedly connected to multiple sliding plates.

[0011] Preferably, multiple spring hinges are fixedly connected inside the arc-shaped box, with the multiple spring hinges arranged in pairs, and each pair of spring hinges offsetting each other.

[0012] Preferably, the wire positioning assembly includes a wire fixing rod fixedly installed on the side wall of the body, a wire fixing ring fixedly connected to the wire fixing rod, a wire clamping ring threadedly connected to the wire fixing rod, a wire roller rotatably connected to the wire fixing rod, the wire roller being located between the wire fixing ring and the wire clamping ring, and a plurality of guide rods fixedly connected to the body, each of the guide rods having a tensioning wheel rotatably connected to its end.

[0013] Preferably, the arc-shaped box is fixedly connected to a right-angle mounting plate, the right-angle mounting plate is fixedly connected to a cutting hydraulic cylinder, and the output end of the cutting hydraulic cylinder is fixedly connected to a cutting blade.

[0014] The beneficial effects of this invention are:

[0015] 1. First, during the winding process, the movement trajectory of the insulation material is restricted by the through slot and spring hinge, so that the insulation material is always located on the outside of the coil skeleton wire, ensuring the winding quality. During the winding process, intermittent compression is formed on the insulation material wrapped on the outermost part of the coil skeleton, making the connection between the insulation material and the wire tighter. Furthermore, through compression, the generation of air bubbles can be effectively reduced, improving the winding quality.

[0016] 2. Secondly, during the winding process, especially after the insulation material is cut, the round rod will intermittently abut against the insulation material wound on the coil frame to prevent the end of the insulation material wound on the coil frame from losing its restraint and disconnecting from the coil frame after the insulation material is cut. During the subsequent winding of the wire, the insulation material will wrinkle, which can further improve the winding effect.

[0017] 3. Then, during the winding process, it will move in a direction perpendicular to the winding direction of the insulating layer material, which can further compress the insulating layer material and increase the compression range.

[0018] 4. During this process, the square cylinder drives the extrusion frame and the round rod to move closer to the outermost insulating material wound around the coil frame, forming a further extrusion between the insulating material and the wire. At this time, the degree of extrusion on the insulating material and the wire is higher, that is, the extrusion force on the insulating material and the wire is greater. However, the extrusion time on the insulating material and the wire is shorter, so it will not damage the insulating material and the wire. The structure is simple and the practical effect is good.

Detailed Implementation

[0031] See Figures 1-11An automatic coil winding device for manufacturing electronic transformers includes a body 1, a rotating component 2 installed inside the body 1, a clamping component 3 installed on the side wall of the body 1, the clamping component 3 and the rotating component 2 being opposite each other, a wire positioning component 4 installed inside the body 1, and an insulation layer positioning component 5 also installed inside the body 1.

[0032] First, the rotating assembly 2 includes a slow-speed motor fixedly installed inside the main body 1. A rotating hydraulic cylinder is fixedly connected to the output end of the slow-speed motor, and a fixed disc 21 is fixedly connected to the output end of the rotating hydraulic cylinder. The clamping assembly 3 includes a frame 31 slidably installed on the side wall of the main body 1. A clamping cylinder 32 is fixedly connected to the upper side of the frame 31, and a fixed cylinder 33 is threadedly connected to the clamping cylinder 32. The fixed cylinder 33 and the fixed disc 21 are opposite each other. Multiple fixing bolts 34 are threadedly installed on the upper side of the frame 31. Before the winding operation, the coil skeleton to be wound is placed between the fixed disc 21 and the fixed cylinder 33. The frame 31 is moved until the coil skeleton abuts against the fixed disc 21 and the fixed cylinder 33. The fixing bolts 34 are used to fix the frame 31 to the main body 1, thus completing the clamping and fixing operation of the coil skeleton. Then, the wire is positioned. Component 4 includes a wire fixing rod 41 fixedly installed on the side wall of the main body 1. A wire fixing ring 42 is fixedly connected to the outer side of the wire fixing rod 41, and a wire clamping ring 43 is also threadedly connected to the outer side of the wire fixing rod 41. A wire roller 44 is rotatably connected to the outer side of the wire fixing rod 41, and the wire roller 44 is located between the wire fixing ring 42 and the wire clamping ring 43. A wire for winding is wound around the outer side of the wire roller 44. Multiple guide rods 7 are fixedly connected to the side wall of the main body 1, and a tensioning wheel 8 is rotatably connected to the end of each guide rod 7. During the winding operation, one end of the wire is fixed to the coil frame. During the winding process, the wire and the tensioning wheel 8 abut against each other. Under the action of the tensioning wheel 8, not only can the movement of the wire be restricted, but the tension of the wire during the winding process can also be automatically adjusted to keep the wire in a normal tension state.

[0033] The insulation layer positioning assembly 5 includes a fixed box fixedly installed on the side wall of the main body 1. A rotating roller is rotatably mounted inside the fixed box, and an insulation layer material (a suitable insulation layer material is selected based on the actual working conditions, such as polyester film tape; compared with other insulation layer materials, polyester film tape has low cost, high dielectric strength, and good flexibility, but its temperature resistance is approximately 105-130℃) is wound around the outside of the rotating roller. A moving hydraulic cylinder for controlling the movement of the rotating roller is also installed inside the fixed box. Then, a controller is installed inside the main body 1, and a display screen is fixedly connected to the outside of the main body 1. The controller is electrically connected to the display screen, motor, rotating hydraulic cylinder, and moving hydraulic cylinder via wires. The controller can control the motor and rotating hydraulic cylinder, controlling their operating parameters (such as the direction and speed of motor rotation, and the direction and speed of movement of the rotating and moving hydraulic cylinders), and these parameters can be displayed to the operator.

[0034] During the winding operation, a layer of insulating material is first wound around the coil frame, followed by a layer of wire. Then, both insulating material and wire are wound around the outside of the wire simultaneously. During this process, a moving hydraulic cylinder is activated by the controller, which drives the rotating roller to move and automatically adjust the position of the insulating material. Because the wire is extremely thin, the area of ​​the wire winding is not very large when the insulating material has been wound from one end of the coil frame to the other. Therefore, the insulating material needs to be cut. When the wire is wound from one end of the coil frame to the other, a length of the insulating material is left at the end after the previous cutting and is directly attached to the baffle of the coil frame or the surface of the previous layer of insulating material. When winding the next layer of wire, the main body automatically adjusts the position of the wound wire so that the wire covers the reserved part of the tape, ensuring that the insulating material completely wraps the edge of the wire. The entire device repeats the above operation until the number of wire layers wound around the outside of the coil frame meets the working requirements.

[0035] An extrusion assembly 6 is mounted on the outside of the insulation layer positioning assembly 5. The extrusion assembly 6 includes a control hydraulic cylinder 601 fixedly connected to the insulation layer positioning assembly 5. An arc-shaped box 602 is fixedly connected to the output end of the control hydraulic cylinder 601. Two through slots 614 are opened on the outside of the arc-shaped box 602. A right-angle mounting plate is fixedly connected to the arc-shaped box 602. A cutting hydraulic cylinder 610 is fixedly connected to the right-angle mounting plate. A cutter 611 is fixedly connected to the output end of the cutting hydraulic cylinder 610. A moving frame 613 is slidably connected to the two through slots 614. Multiple round rods 617 are connected to the moving frame 613 through a connecting assembly. The arc-shaped box 602... A rotating rod 607 is rotatably connected to the side wall of component 02. A first gear 605 is fixedly connected to the outer side of the rotating rod 607. A movable ring 603 is slidably connected to the side wall of component 1. The movable ring 603 is rotatably connected to the rotating assembly 2. A first rack 604 is fixedly connected to the side wall of the movable ring 603. The first rack 604 meshes with the first gear 605. An annular groove 624 is opened on the outer side of the rotating rod 607. A sliding rod 625 is slidably connected in the annular groove 624. A sleeve 623 is fixedly connected to the outer side of the sliding rod 625. The sleeve 623 is fixedly connected to the movable frame 613 through a first connecting rod 622.

[0036] The connecting assembly includes two movable blocks 619 that are slidably connected to the movable frame 613. A first spring 620 is fixedly connected between the two movable blocks 619 and the movable frame 613. A square rod 618 is fixedly connected to the outside of the movable blocks 619. A square cylinder 612 is slidably connected to the outside of the square rod 618. A second spring is fixedly connected between the square cylinder 612 and the square rod 618. A pressing frame 606 is fixedly connected to the outside of the square cylinder 612. A plurality of pressing rods 616 are rotatably connected through the pressing frame 606. A round rod 617 is fixedly connected to the pressing rods 616.

[0037] First, both the control hydraulic cylinder 601 and the cutting hydraulic cylinder 610 are electrically connected to the controller inside the main body 1 via wires. The controller can also control the direction and speed of movement of the control hydraulic cylinder 601 and the cutting hydraulic cylinder 610. Second, during the winding operation, when the insulating material is wound from one end of the coil frame to the other, the controller can automatically activate the cutting hydraulic cylinder 610. The cutting hydraulic cylinder 610 drives the cutter 611 to move, cutting the insulating material. Then, during the winding process, after one layer of wire is wound, the controller automatically activates the control hydraulic cylinder 601, causing it to move the arc-shaped box 602. This allows the arc-shaped box 602 to automatically adjust its position. Since the insulating material always penetrates the through slot 614, the arc-shaped box 602, whose position changes, will automatically adjust the position of the insulating material, ensuring that the insulating material remains outside the wire wound around the coil frame.

[0038] Then, during the winding process, the arc-shaped box 602 moves relative to the first rack 604, causing the first gear 605 to rotate. The first gear 605 drives the rotating rod 607 to rotate. Due to the special shape of the annular groove 624 on the outer side of the rotating rod 607, the unfolded schematic diagram of the annular groove 624 can be divided into two parts: a straight part and a curved part. When the sliding rod 625 is in the straight part, the sleeve 623 will not move relative to the rotating rod 607. Since the rotating rod 607 and the arc-shaped box 602 are in a rotatable connection state, the sleeve 623, the first connecting rod 622, and the moving frame 613 are in a fixed connection state. Therefore, at this time, the moving frame 613 will not move relative to the arc-shaped box 602.

[0039] When the slide rod 625 is located in the curved section, the action of the slide rod 625 and the annular groove 624 causes the sleeve 623 to move relative to the rotating rod 607. That is, at this time, the moving frame 613 will move relative to the arc-shaped box 602. Since the moving frame 613 is slidably connected to the outside of the moving block 619, and the outside of the moving block 619 is slidably connected to the pressing frame 606, and the outside of the pressing frame 606 is rotatably connected to the round rod 617, specifically regarding the round rod 617 and the insulating material wound on the outermost side of the coil frame, the round rod 617 first abuts against the insulating material wound on the outermost side of the coil frame, forming a pressing on the insulating material wound on the outermost side of the coil frame. Then, after disconnecting from the insulating material wound on the outermost side of the coil frame for a period of time, it abuts against the insulating material wound on the outermost side of the coil frame again, which can form an intermittent pressing on the insulating material wound on the outermost side of the coil frame, making the connection between the insulating material and the wire tighter.

[0040] Furthermore, the extrusion effectively reduces the generation of air bubbles and improves the winding effect. After the insulation material is cut, the round rod 617 will intermittently abut against the insulation material wound on the coil frame to prevent the end of the insulation material wound on the coil frame from losing its restraint and disconnecting from the coil frame after the insulation material is cut. During the subsequent winding of the wire, the insulation material will wrinkle, which can further improve the winding effect.

[0041] Under the action of the first spring 620, part of the movement of the arc-shaped box 602 relative to the coil frame can be eliminated (another part is eliminated by disconnecting the round rod 617 from the insulating material wrapped around the outermost part of the coil frame).

[0042] A control component for controlling the movement of the moving block 619 is installed on the outside of the arc-shaped box 602. The control component includes a second connecting rod 621 fixedly installed on the side wall of the moving block 619. A rotating disk 608 is fixedly connected to the outside of the rotating rod 607. Multiple support rods 609 are fixedly connected to the outside of the rotating disk 608 in a circumferential direction.

[0043] First, when the slide rod 625 is located in the straight section of the annular groove 624, the support rod 609 and the second connecting rod 621 are in a staggered state. At this time, the first gear 605 drives the rotating disk 608 and the support rod 609 to rotate, but the support rod 609 will not drive the second connecting rod 621 to move. When the slide rod 625 is located in the arc-shaped section of the annular groove 624, it will drive the moving frame 613 to move relative to the arc-shaped box 602, which will cause the rotating second connecting rod 621 to abut against it and thus drive the second connecting rod 621 to move. 1. The moving block 619 is moved, and the moving block 619 moves the extrusion frame 606 through the square rod 618 and the square cylinder 612. The extrusion frame 606 moves the round rod 617 through the extrusion rod 616. During this process, especially when the slide rod 625 just enters the arc-shaped part of the annular slide groove 624, the round rod 617 is still in contact with the insulating layer material. Therefore, at this time, the round rod 617 is in contact with the insulating layer material and will move in a direction perpendicular to the winding direction of the insulating layer material, which can further extrude the insulating layer material and increase the extrusion range.

[0044] A third connecting rod 627 is fixedly connected to the outer side of the square tube 612, and inclined plates 628 are fixedly connected to both sides of the movable frame 613.

[0045] When the moving block 619 moves relative to the moving frame 613, the moving block 619 drives the square rod 618 and the square cylinder 612 to move relative to the moving frame 613. At this time, the third connecting rod 627 on the outside of the square cylinder 612 abuts against the inclined plate 628. Under the obstruction of the inclined plate 628, the square cylinder 612 will move away from the moving frame 613. The square cylinder 612 drives the extrusion frame 606 and the round rod 617 to move closer to the insulation material wound on the outermost side of the coil frame, forming a further extrusion between the insulation material and the wire. Unlike the slide rod 625 in the straight part of the annular groove 624, the degree of extrusion on the insulation material and the wire is higher at this time, that is, the extrusion force on the insulation material and the wire is greater. However, the extrusion time on the insulation material and the wire is shorter in this process, so it will not damage the insulation material and the wire.

[0046] Multiple sliding plates 626 are fixedly connected to the outer side of the third connecting rod 627;

[0047] During the movement of the third connecting rod 627, the third connecting rod 627 will drive the sliding plate 626 to move. During this process, if the insulating material is stuck to the outside of the arc-shaped box 602, the sliding plate 626 will act as a contact point between the sliding plate 626 and the insulating material, which will greatly reduce the possibility of the insulating material sticking to the outside of the arc-shaped box 602, so that the winding operation can continue to run normally.

[0048] Multiple spring hinges 615 are fixedly connected inside the arc-shaped box 602. The multiple spring hinges 615 are in pairs, and each pair of spring hinges 615 abuts against each other. The spring hinges 615 are used to complete the clamping and restraining operation of the insulating material.

[0049] In this invention, before the winding operation, the coil skeleton to be wound is fixedly installed between the fixed disc 21 and the fixed cylinder 33. A layer of insulating material is wound on the coil skeleton, and then a layer of wire is wound on the insulating material. Then, the insulating material and the wire are wound on the outside of the wire at the same time. During this process, the controller starts the moving hydraulic cylinder, which drives the rotating roller to move and automatically adjusts the position of the insulating material. When the insulating material is wound from one end of the coil skeleton to the other end, the insulating material is cut off. A length of the end of the insulating material is reserved and directly glued to the baffle of the coil skeleton or the surface of the previous layer of insulating material. When winding the next layer of wire, the body automatically adjusts the position of the wound wire so that the wire covers the reserved part of the tape, ensuring that the insulating material completely wraps the edge of the wire. The whole device repeats the above operation until the number of wire layers wound on the outside of the coil skeleton meets the working requirements.

[0050] During the winding process, the arc-shaped box 602 moves relative to the first rack 604, and the first gear 605 rotates. The first gear 605 drives the rotating rod 607 to rotate. When the slide rod 625 is located in the straight section of the annular groove 624, the sleeve 623 will not move relative to the rotating rod 607, that is, the moving frame 613 will not move relative to the arc-shaped box 602. When the slide rod 625 is located in the curved section of the annular groove 624, the sleeve 623 moves relative to the rotating rod 607, that is, the moving frame 613 will move relative to the arc-shaped box 602. Specifically, regarding the round rod 617 and the insulating material wound on the outermost side of the coil frame, the round rod 617 first abuts against the insulating material wound on the outermost side of the coil frame, forming a contact with the insulating material wound on the outermost side of the coil frame. The insulation material is compressed, and after a period of disconnection from the insulation material wound on the outermost side of the coil frame, it is pressed against the insulation material wound on the outermost side of the coil frame again. This intermittent compression of the insulation material wound on the outermost side of the coil frame makes the connection between the insulation material and the wire tighter. The compression can effectively reduce the generation of air bubbles and improve the winding effect. After the insulation material is cut, the round rod 617 will intermittently press against the insulation material wound on the coil frame to prevent the end of the insulation material wound on the coil frame from losing its restraint and disconnecting from the coil frame after the insulation material is cut. During the subsequent wire winding process, the insulation material will wrinkle, which can further improve the winding effect.

[0051] When the slide rod 625 is located in the arc-shaped part of the annular slide groove 624, it will drive the moving frame 613 to move relative to the arc-shaped box 602, which will cause the rotating support rod 609 and the second connecting rod 621 to abut against each other, thereby driving the second connecting rod 621 to move. The second connecting rod drives the extrusion frame 606 to move through the moving block 619, the square rod 618 and the square cylinder 612. The extrusion frame 606 drives the round rod 617 to move through the extrusion rod 616. During this process, especially when the slide rod 625 just enters the arc-shaped part of the annular slide groove 624, the round rod 617 is still abutting against the insulating material. Therefore, at this time, the round rod 617 abutting against the insulating material will form a movement in a direction perpendicular to the winding direction of the insulating material, which can further extrude the insulating material and increase the extrusion range.

[0052] When the moving block 619 moves relative to the moving frame 613, the moving block 619 drives the square rod 618 and the square cylinder 612 to move relative to the moving frame 613. At this time, the third connecting rod 627 on the outside of the square cylinder 612 abuts against the inclined plate 628. Under the obstruction of the inclined plate 628, the square cylinder 612 will move away from the moving frame 613. The square cylinder 612 drives the extrusion frame 606 and the round rod 617 to move closer to the insulation material wound on the outermost side of the coil frame, forming a further extrusion between the insulation material and the wire. Unlike the slide rod 625 in the straight part of the annular groove 624, the degree of extrusion on the insulation material and the wire is higher at this time, that is, the extrusion force on the insulation material and the wire is greater.
