Description

Technical Field

[0001] The present invention relates to the technical field of electronic transformers, and in particular to automatic coil winding equipment for producing electronic transformers. Background Art

[0002] An electronic transformer is a device that uses high-frequency switching technology and electronic components to achieve voltage conversion, isolation, and power transmission. It is one of the core achievements of modern electronic technology. The coil of an electronic transformer is one of its core components. Its design and winding process directly determine the performance of the transformer (such as efficiency, temperature rise, leakage inductance, distributed capacitance, etc.). Currently, it is mainly completed by an automatic winding machine. First, the bobbin is fixed to the automatic winding machine, and one end of the wire is fixed to the bobbin. The automatic winding machine is started to wind the wire 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 work requirements. Finally, the coil winding operation is completed. The overall operation is highly automated and intelligent. The tape is then automatically wound around the conductor, but unlike the conductor, the tape is wider, so when the conductor is only wound a certain width, the tape is already wrapped around the conductor. Therefore, the machine needs to be stopped to cut the tape before the conductor is wound around. As a result, in the subsequent winding process, one end of the tape wrapped around the conductor has no fixing device. In the subsequent winding process, the end of the tape will be disconnected from the coil frame, resulting in the possibility of wrinkles at the end of the tape during the subsequent winding process, thereby affecting the subsequent winding work. In addition, there is no device for squeezing the tape, and the tape is only fixed by its own viscosity. The fixing effect is average, and there is a high probability of bubbles, which further reduces the winding effect. Therefore, an automatic coil winding device for the production of electronic transformers is provided. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic coil winding device for the production of electronic transformers.

[0007] Preferably, the square tube is fixedly connected to a third connecting rod, and the movable frame is fixedly connected to an inclined plate.

[0008] Preferably, the second connecting rod is fixedly connected to a plurality of slide plates.

[0009] Preferably, a plurality of spring hinges are fixedly connected in the arc-shaped box, the plurality of spring hinges are grouped in pairs, and the spring hinges in each group offset each other.

[0010] Preferably, the wire positioning assembly includes a wire fixing rod fixedly mounted on the side wall of the body, the wire fixing rod is fixedly connected to a wire fixing ring, the wire fixing rod is threadedly connected to a wire clamping ring, the wire fixing rod is rotatably connected to a wire roller, the wire roller is located between the wire fixing ring and the wire clamping ring, the body is fixedly connected to a plurality of guide rods, and the end of each guide rod is rotatably connected to a tensioning wheel.

[0011] Preferably, the arc 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 cutter.

[0012] The beneficial effects of the present invention are: 1. First, during the winding process, the through groove and spring fold limit the movement trajectory of the insulation material, so that the insulation material is always located outside the coil frame conductor, ensuring the winding quality. In addition, during the winding process, the insulation material wound on the outermost side of the coil frame is intermittently squeezed, so that the connection between the insulation material and the conductor is tighter. The squeezing can effectively reduce the generation of bubbles and improve the winding quality. 2. Secondly, during the winding process, especially after the insulating layer material is cut off, the round rod will intermittently offset the insulating layer material wound on the coil skeleton to prevent the insulating layer material end wound on the coil skeleton from losing restraint and disconnecting from the coil skeleton after the insulating layer material is cut off. In the subsequent wire winding process, the insulating layer material will be wrinkled, which can further improve the winding effect; 3. Then, during the winding process, the insulating material will move in a direction perpendicular to the winding direction, which can further squeeze the insulating material and increase the squeezing range; 4. In this process, the square tube drives the extrusion frame and the round rod as a whole to move closer to the insulating layer material wound on the outermost side of the coil skeleton, thereby further squeezing the insulating layer material and the wire. At this time, the degree of squeezing the insulating layer material and the wire is higher, that is, the squeezing force on the insulating layer material and the wire is greater. However, the squeezing time of the insulating layer material and the wire is shorter in this process, so it will not cause damage to the insulating layer material and the wire. The structure is simple and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] See Figures 1-11 , an automatic coil winding device for manufacturing electronic transformers, comprising a body 1, a rotating assembly 2 installed in the body 1, a clamping assembly 3 installed on the side wall of the body 1, the clamping assembly 3 and the rotating assembly 2 facing each other, a wire positioning assembly 4 installed in the body 1, and an insulation layer positioning assembly 5 also installed in the body 1; First, the rotating component 2 includes a slow-speed motor fixedly installed in the main body 1, the output end of the slow-speed motor is fixedly connected to a rotating hydraulic cylinder, the output end of the rotating hydraulic cylinder is fixedly connected to a fixed disc 21, the clamping component 3 includes a frame 31 slidably installed on the side wall of the main body 1, the upper side of the frame 31 is fixedly connected to a clamping cylinder 32, the clamping cylinder 32 is internally threadedly connected to a fixing cylinder 33, the fixing cylinder 33 and the fixed disc 21 are opposite, and a plurality of 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, and the frame 31 is moved until the coil skeleton and the fixed disc 21 and the fixed cylinder 33 are against each other, and the fixing bolts 34 are used to fix the frame 31 and the main body 1, thereby completing the clamping and fixing operation of the coil skeleton, and then the wire is positioned The component 4 includes a wire fixing rod 41 fixedly mounted on the side wall of the main body 1, and a wire fixing ring 42 is fixedly connected to the outer side of the wire fixing rod 41. 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. The wire roller 44 is located between the wire fixing ring 42 and the wire clamping ring 43. The outer side of the wire roller 44 is wound with a wire for winding. A plurality of guide rods 7 are fixedly connected to the side wall of the main body 1, and the end of each guide rod 7 is rotatably connected to a tensioning wheel 8. When the winding operation is performed, one end of the wire is fixed to the coil skeleton. During the winding process, the wire and the tensioning wheel 8 are counteracted. Under the action of the tensioning wheel 8, it can not only limit the movement of the wire, but also automatically adjust the tension of the wire during the winding process, so that the wire is always in a normal tensioned state. The insulating layer positioning assembly 5 includes a fixed box fixedly installed on the side wall of the main body 1, a rotating roller is rotatably installed in the fixed box, and an insulating layer material is wrapped around the outside of the rotating roller (the appropriate insulating layer material is selected according to the actual working conditions, such as polyester film tape. Compared with other insulating layer materials, polyester film tape has low cost, high dielectric strength, good flexibility, but is temperature-resistant at about 105-130°C). A mobile hydraulic cylinder for controlling the movement of the rotating roller is also installed in the fixed box. Then, a controller is installed in 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 mobile hydraulic cylinder through wires. The motor and rotating hydraulic cylinder can be controlled by the controller to control their operating parameters (such as the direction and speed of motor rotation, the direction and speed of movement of the rotating hydraulic cylinder and the mobile hydraulic cylinder, etc.), and can be presented to the staff through the display screen. During the winding operation, a layer of insulating material is first wound on the coil skeleton, and then a layer of wire is wound on the insulating material, and then the insulating material and the wire are wound on the outside of the wire at the same time. During this process, the mobile hydraulic cylinder is started by the controller, and the mobile hydraulic cylinder drives the rotating roller to move and automatically adjust the position of the insulating material. Since the wire is extremely thin, during the simultaneous winding process, when the insulating material has been wound from one end of the coil skeleton to the other end of the coil skeleton, the winding range of the wire is not very large, so it is necessary to cut the insulating material. When the wire is wound from one end of the coil skeleton to the other end of the coil skeleton, after the previous insulating material is cut off, the end of the insulating material will reserve a certain length and directly stick to the baffle of the coil skeleton or the surface of the insulating material of the previous layer. When winding the next layer of wire, the main body will automatically adjust the position of the wound wire so that the wire covers the reserved part of the tape to ensure that the insulating material completely wraps the edge of the wire. The device as a whole repeats the above operation until the number of layers of wire wound on the outside of the coil skeleton meets the working needs; The outer side of the insulating layer positioning component 5 is equipped with an extrusion component 6, which includes a control hydraulic cylinder 601 fixedly connected to the insulating layer positioning component 5. The output end of the control hydraulic cylinder 601 is fixedly connected to the arc box 602. Two through slots 614 are opened on the outer side of the arc box 602. The arc box 602 is fixedly connected to a right-angle mounting plate. The right-angle mounting plate is fixedly connected to a cutting hydraulic cylinder 610. The output end of the cutting hydraulic cylinder 610 is fixedly connected to a cutter 611. The two through slots 614 are slidably connected to a moving frame 613. The moving frame 613 is connected to a plurality of round rods 617 through a connecting component. The arc box 6 02 The side wall is rotatably connected with a rotating rod 607, and the outer side of the rotating rod 607 is fixedly connected with a first gear 605. The side wall of the body 1 is slidably connected with a moving ring 603. The moving ring 603 is rotatably connected to the rotating component 2. The side wall of the moving ring 603 is fixedly connected with a first rack 604. The first rack 604 and the first gear 605 are engaged. 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. The outer side of the sliding rod 625 is fixedly connected with a sleeve 623. The sleeve 623 is fixedly connected to the moving frame 613 through the first connecting rod 622. The connecting assembly includes two moving blocks 619 that are slidably connected to the moving frame 613. A first spring 620 is fixedly connected between the two moving blocks 619 and the moving frame 613. A square rod 618 is fixedly connected to the outside of the moving block 619. A square tube 612 is slidably connected to the outside of the square rod 618. A second spring is fixedly connected between the square tube 612 and the square rod 618. An extrusion frame 606 is fixedly connected to the outside of the square tube 612. A plurality of extrusion rods 616 are rotatably connected through the extrusion frame 606. A round rod 617 is fixedly connected to the extrusion rod 616. First, the control hydraulic cylinder 601 and the cutting hydraulic cylinder 610 are electrically connected to the controller in the main body 1 through wires, and the moving direction and speed of the control hydraulic cylinder 601 and the cutting hydraulic cylinder 610 can also be controlled by the controller. Secondly, during the winding operation, when the insulating layer material is wound from one end of the coil skeleton to the other end of the coil skeleton, the controller can automatically start the cutting hydraulic cylinder 610, and the cutting hydraulic cylinder 610 drives the cutter 611 to move and cut the insulating layer material. Then, in the winding process, after a layer of wire is wound, the controller will automatically start the control hydraulic cylinder 601, so that the control hydraulic cylinder 601 drives the arc box 602 to move, and then the arc box 602 can automatically adjust its position. Since the insulating layer material has been running through the through slot 614, the arc box 602 whose position has changed will automatically adjust the position of the insulating layer material so that the insulating layer material is always located outside the wire wound on the coil skeleton. Then, during the winding process, the arc box 602 will move relative to the first rack 604, thereby causing the first gear 605 to rotate, and 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 expanded schematic diagram of the annular groove 624 can be divided into two parts, namely the straight part and the curved part. When the slide bar 625 is located in the straight part, the sleeve 623 will not move relative to the rotating rod 607. Since the rotating rod 607 and the arc box 602 are in a rotationally connected state, the sleeve 623, the first connecting rod 622, and the moving frame 613 are in a fixedly connected state. Therefore, at this time, the moving frame 613 will not move relative to the arc box 602. When the sliding rod 625 is located in the curved part, under the action of the sliding rod 625 and the annular sliding groove 624, the sleeve 623 will move relative to the rotating rod 607, that is, at this time the moving frame 613 will move relative to the arc box 602. Since the outer side of the moving frame 613 is slidingly connected to the moving block 619, the outer side of the moving block 619 is slidingly connected to the extrusion frame 606, and the outer side of the extrusion frame 606 is rotatably connected to the round rod 617, so specifically with respect to the round rod 617 and the insulating layer material wrapped on the outermost side of the coil skeleton, the round rod 617 first offsets the insulating layer material wrapped on the outermost side of the coil skeleton to form an extrusion of the insulating layer material wrapped on the outermost side of the coil skeleton, and then disconnects from the insulating layer material wrapped on the outermost side of the coil skeleton for a period of time, and then offsets the insulating layer material wrapped on the outermost side of the coil skeleton again, which can form an intermittent extrusion of the insulating layer material wrapped on the outermost side of the coil skeleton, making the connection between the insulating layer material and the wire tighter. Furthermore, through extrusion, the generation of bubbles can be effectively reduced, and the winding effect can be improved. Moreover, after the insulating layer material is cut, the round rod 617 will intermittently abut the insulating layer material wound on the coil skeleton, thereby preventing the insulating layer material end portion wound on the coil skeleton from losing restraint and disconnecting from the coil skeleton after the insulating layer material is cut, and preventing the insulating layer material from wrinkling during the subsequent wire winding process, thereby further improving the winding effect. Under the action of the first spring 620, a part of the movement of the arc box 602 relative to the coil bobbin can be eliminated (the other part is eliminated by disconnecting the round rod 617 and the insulating layer material wrapped around the outermost side of the coil bobbin).

[0016] A control assembly for controlling the movement of the moving block 619 is installed on the outside of the arc box 602. The control assembly includes a second connecting rod 621 fixedly mounted on the side wall of the moving block 619. A rotating disc 608 is fixedly connected to the outside of the rotating rod 607. A plurality of support rods 609 are fixedly connected to the outside of the rotating disc 608 along its circumference. First, when the slide bar 625 is located in the straight portion of the annular slot 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 disc 608 and the support rod 609 to rotate, but the support rod 609 does not drive the second connecting rod 621 to move. When the slide bar 625 is located in the arc portion of the annular slot 624, it drives the moving frame 613 to move relative to the arc box 602, thereby causing the rotating second connecting rod 621 to resist and drive the second connecting rod 621 to move. 1 drives the moving block 619 to move, and the moving block 619 drives the extrusion frame 606 to move through 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 sliding rod 625 just enters the arc portion of the annular chute 624, the round rod 617 is still against the insulating layer material. Therefore, at this time, the round rod 617 is against the insulating layer material, which will form a movement 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.

[0017] The outer side of the square tube 612 is fixedly connected to a third connecting rod 627, and both outer sides of the moving frame 613 are fixedly connected to inclined plates 628; When the moving block 619 moves relative to the moving frame 613, the moving block 619 drives the square rod 618 and the square tube 612 to move relative to the moving frame 613. At this time, the third connecting rod 627 and the inclined plate 628 on the outside of the square tube 612 are against each other. Under the obstruction of the inclined plate 628, the square tube 612 will move away from the moving frame 613. The square tube 612 drives the extrusion frame 606 and the round rod 617 as a whole to move closer to the insulating layer material wound on the outermost side of the coil skeleton, forming further extrusion between the insulating layer material and the wire. Different from the straight part of the slide bar 625 in the annular groove 624, the degree of extrusion on the insulating layer material and the wire is higher, that is, the extrusion force on the insulating layer material and the wire is greater, but the extrusion time of the insulating layer material and the wire is shorter in this process, so it will not cause damage to the insulating layer material and the wire.

[0018] A plurality of slide plates 626 are fixedly connected to the outer side of the third connecting rod 627; During the movement of the third connecting rod 627, the third connecting rod 627 will drive the slide 626 to move. During this process, if the insulating layer material sticks to the outside of the arc box 602, under the action of the slide 626, the slide 626 and the insulating layer material will offset each other, which will greatly reduce the possibility of the insulating layer material sticking to the outside of the arc box 602, so that the winding work can continue to operate normally.

[0019] A plurality of spring hinges 615 are fixedly connected in the arc-shaped box 602 . The plurality of spring hinges 615 are arranged in pairs, and each group of spring hinges 615 is offset against each other. The spring hinges 615 are used to complete the clamping and limiting operation of the insulating layer material.

[0020] In the present invention, before the winding operation is performed, 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, and then the insulating material and the wire are wound on the outside of the wire at the same time. During this process, the mobile hydraulic cylinder is started by the controller, and the mobile hydraulic cylinder drives the rotating roller to move, automatically adjusting the position of the insulating material. When the insulating material is wound from one end of the coil skeleton to the other end of the coil skeleton, the insulating material is cut off, and a length of the end of the insulating material is reserved and directly adhered to the baffle of the coil skeleton or the surface of the insulating material of the previous layer. 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 device as a whole repeats the above operation until the number of layers of wire wound on the outside of the coil skeleton meets the working requirements; During the winding process, the arc box 602 moves relative to the first rack 604, the first gear 605 rotates, and the first gear 605 drives the rotating rod 607 to rotate. When the sliding rod 625 is located in the straight part of the annular slot 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 box 602. When the sliding rod 625 is located in the curved part of the annular slot 624, the sleeve 623 moves relative to the rotating rod 607, that is, at this time the moving frame 613 will move relative to the arc box 602. Specifically, with respect to the round rod 617 and the insulating layer material wound on the outermost side of the coil skeleton, the round rod 617 first offsets the insulating layer material wound on the outermost side of the coil skeleton, forming a counterweight to the insulating layer material wound on the outermost side of the coil skeleton. The insulating layer material is extruded, and then disconnected from the insulating layer material wound on the outermost side of the coil skeleton for a period of time, and then offset against the insulating layer material wound on the outermost side of the coil skeleton again, which can form an intermittent extrusion of the insulating layer material wound on the outermost side of the coil skeleton, so that the connection between the insulating layer material and the wire is tighter, and through extrusion, the generation of bubbles can be effectively reduced, and the winding effect can be improved. After the insulating layer material is cut off, the round rod 617 will intermittently offset against the insulating layer material wound on the coil skeleton, preventing the end of the insulating layer material wound on the coil skeleton from losing restraint and disconnecting from the coil skeleton after the insulating layer material is cut off. In the subsequent wire winding process, the insulating layer material will be wrinkled, which can further improve the winding effect. When the slide bar 625 is located in the arc portion of the annular chute 624, it drives the moving frame 613 to move relative to the arc box 602, thereby causing 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 tube 612, and the extrusion frame 606 drives the round rod 617 to move through the extrusion rod 616. During this process, especially when the slide bar 625 just enters the arc portion of the annular chute 624, the round rod 617 is still abutted against the insulating layer material. Therefore, at this time, the round rod 617 is abutted against the insulating layer material, which will form a movement 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. When the moving block 619 moves relative to the moving frame 613, the moving block 619 drives the square rod 618 and the square tube 612 to move relative to the moving frame 613. At this time, the third connecting rod 627 and the inclined plate 628 on the outside of the square tube 612 are against each other. Under the obstruction of the inclined plate 628, the square tube 612 will move away from the moving frame 613. The square tube 612 drives the extrusion frame 606 and the round rod 617 as a whole to move closer to the insulating layer material wound on the outermost side of the coil skeleton, thereby further squeezing the insulating layer material and the wire. Different from the straight part of the slide bar 625 in the annular groove 624, the degree of squeezing of the insulating layer material and the wire is higher, that is, the squeezing force on the insulating layer material and the wire is greater.
