Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to a winding device for a transformer coil. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization (magnetic saturation transformer). All components of the transformer need to be industrially produced, and there are certain requirements for their quality during the production process.

[0003] During the production process of transformer coils, the problem of coil slack often occurs during winding. There are also technical solutions to this problem in the prior art. For example, application No. 202011612096.9 discloses an intelligent winding device for transformer coils, which "is provided with a wire box, and a wire pressing mechanism is provided inside the wire box. We add a suitable counterweight block to the wire pressing mechanism, so that different copper wires of different thicknesses can be tightened, that is, it can ensure that the copper wires of each circle are very close and there is no slack." The enameled wire can be tightened to remove the slack, but the enameled wire on the pay-off roller will also move left and right on the pay-off roller during the pay-off process, and the enameled wire will inevitably bend and cause friction when passing through the wire mouth slot from the conductor roller to the threading block, which affects the service life of the coil;

[0004] The technical solution "is provided with a clamping mechanism. We pass the copper wire wound on the winding roller through the round hole, pull the pull ring upwards to wind the copper wire under the pressure plate, and the anti-slip protrusion under the pressure plate can prevent the copper wire from loosening. Then, loosen the pull ring and under the action of the first spring, the copper wire can be compressed. In this way, the wire end can be fixed before winding to prevent loosening, and the winding quality is improved." The winding quality can be further improved. The winding roller is already driven by a motor, and there is no need for a pressure plate to act on the shaft of the winding roller. The pressure plate may even affect the operation of the motor and its service life. Summary of the invention

[0017] Technical effects and advantages of the transformer coil winding device:

[0018] When the winding device of the transformer coil is used to wind the coil, during the winding process, the enameled wire is passed through the limiting hole at the top of the inner cylinder, and then the enameled wire passing through the limiting hole is wound on the winding roller. When the enameled wire is wound on the winding roller, it will be wound back and forth along the outer wall of the winding roller. When the position of the enameled wire moves, the enameled wire will drive the inner cylinder to slide in the outer cylinder, so that the inner cylinder reduces the obstruction to the enameled wire, reduces the possibility of the enameled wire bending and friction in the limiting hole of the inner cylinder, reduces the damage to the enameled wire to a certain extent, and increases the service life of the enameled wire, thereby increasing the service life of the modified coil;

[0019] When the enameled wire is wound on the winding roller, the position of the enameled wire on the pay-off roller will also move. At this time, the first motor is turned on to drive the winding roller, the outer cylinder and the inner cylinder on the top of the movable plate to move, so that the inner cylinder and the position of the enameled wire after the winding are matched, and the winding roller, the limit hole and the pay-off roller are in a straight line as much as possible during the winding process;

[0020] When the device is used for wire winding, according to the tightness of the enameled wire in the actual winding process, the moving block is driven to move upward or downward on the four limit rods by means of a hand-screwed screw, and the moving block acts on the spring and the extrusion block below it, so that the extrusion block increases or decreases the extrusion force on the pay-off roller shaft inserted into the support sleeve, and controls the force required for the pay-off roller to rotate, thereby achieving the effect of controlling the tightness of the enameled wire on the pay-off roller and avoiding affecting the service life of the third motor.

[0044] Please refer to Figure 1-Figure 9 The winding device of a transformer coil shown in the figure comprises a supporting base plate 101, a pay-off roller 221 installed on one side of the top of the supporting base plate 101, an outer cylinder 401 and an inner cylinder 402 located on the top of the supporting base plate 101, and a winding roller 503 located on the top of the supporting base plate 101, two sliding blocks 102 parallel to each other are installed on one side of the top of the supporting base plate 101, first fixing plates 103 are installed on both sides of the top of the supporting base plate 101, the two first fixing plates 103 are located between the two sliding blocks 102 on the top of the supporting base plate 101, and the supporting base plate 101 is located on one side of the two sliding blocks 102 A movable plate 311 is provided on the top, and four support rods 111 distributed in a rectangular array are installed on the other side of the top of the support base plate 101, wherein special-shaped limit plates 112 are installed on the top of two support rods 111 on one side, and lower limit plates 113 are installed on the top of two support rods 111 on the other side, and upper limit plates 114 are installed on the top of the lower limit plates 113, and the rotating shaft of the pay-off roller 221 is clamped at the lower limit plates 113 and the upper limit plates 114. The pay-off roller 221 and the winding roller 503 of the technical solution are both drawn with the rolled enameled wire 222, but their edge positions are all composed of the enameled wire 222.

[0045] In order to reduce the possibility of bending of the enameled wire 222 when it comes out from the pay-off roller 221 and is wound on the winding roller 503, as shown in FIG. Figure 1-Figure 2 , Figure 5-Figure 9As shown, a first motor 301 is installed on a side surface of one of the first fixed plates 103 away from the other first fixed plate 103, and the output shaft of the first motor 301 is coaxially connected with a threaded rod 302, and two sliding limit blocks 312 are installed at the bottom of the movable plate 311, and each sliding limit block 312 is respectively slidably connected to one of the sliding blocks 102, and an engaging block 313 is fixed at the center of the bottom of the movable plate 311, and the engaging block 313 is threadedly sleeved on the outer wall of the threaded rod 302, and a first top cover block 321 and a second top cover block 322 are installed on the top of the movable plate 311 away from the pay-off roller 221, and a tooth plate 341 is slidably provided on the top of the movable plate 311, and a top limit block 342 is fixed on the top of the tooth plate 341, and the tooth plate 341 is slidably connected to the second top cover block 322 via the top limit block 342, and the tooth plate 341 is away from the second top cover A mounting block 343 is fixed on one side of the block 322, a telescopic rod 344 is installed on the top of the mounting block 343, a top support plate 345 is fixed on one retractable end of the telescopic rod 344, two second fixing plates 501 symmetrical about the center of the top support plate 345 are installed on the top of the top support plate 345, a third motor 502 is installed on one side of one of the second fixing plates 501 away from the other second fixing plate 501, a winding roller 503 is coaxially connected to the output shaft of the third motor 502, the height of the top support plate 345 and the winding roller 503 is adjusted by the telescopic rod 344 to make it correspond to the height of the enameled wire 222 on the pay-off roller 221, a fixing rod 504 is installed on one side of the top of the top support plate 345, when a coil is completed, the cut coil is wound around the fixing rod 504 to prevent the enameled wire 222 on the pay-off roller 221 from falling off;

[0046] A first rotating seat 323 is installed on one side of the top of the moving plate 311 close to the pay-off roller 221, and second rotating seats 324 are installed on both sides of the first rotating seat 323 at the top of the moving plate 311. The inner cylinder 402 is rotatably installed on the top of the moving plate 311 through the first rotating seat 323, and the inner cylinder 402 is slidably installed on the inner wall of the outer cylinder 401. A limiting hole 403 is provided on the top of the inner cylinder 402 for passing through and constraining the position of the enameled wire 222. A second motor 331 is installed at the bottom of the moving plate 311, and the output shaft of the second motor 331 is coaxially connected with a gear 332. The first top cover block 321 acts on the output shaft of the second motor 331, and the gear 332 meshes The second motor 331 is used to control the movement of the tooth plate 341, and the position of the gear 332 is limited by the first top cover block 321, so as to improve the safety of the winding device during use. Second rotating seats 324 are installed on both side surfaces of the outer cylinder 401, and two pneumatic rods 404 are rotatably installed between the two second rotating seats 324 on the top of the movable plate 311 and the two second rotating seats 324 on the outer cylinder 401. The structure of the two pneumatic rods 404 is similar to the shock absorber of an electric vehicle, but the force required is smaller, and can be changed according to the force applied by the enameled wire 222 to the inner cylinder 402, so as to reduce the influence on the bending degree of the enameled wire 222.

[0047] In order to improve the tightness of the enameled wire 222 after winding by controlling the force required when the pay-off roller 221 rotates during the winding process, as shown in FIG. Figure 1-Figure 4 As shown, a support sleeve 201 with a central axis of a pay-off roller 221 is installed on one side of the special-shaped limit plate 112 close to the lower limit plate 113, a connecting plate 202 is installed on the top of one side of the support sleeve 201 of the special-shaped limit plate 112, four limit rods 203 distributed in a rectangular array are installed at the bottom of the connecting plate 202, and the connecting plate 202 is threadedly connected to a hand-screw 211 through a threaded hole opened thereon, and a moving block 212 is rotatably connected to the bottom end of the hand-screw 211, and the moving block 212 is sleeved on the four limit rods 203. A spring 213 is connected to a side surface of the moving block 212 away from the hand-screw 211, and an extrusion block 214 is connected to the end of the spring 213 away from the moving block 212. The extrusion block 214 cooperates with the support sleeve 201. The positions of the moving block 212 and the extrusion block 214 are constrained by four limit rods 203 to improve the accuracy of the constrained position. The position of the moving block 212 is changed by the hand-screw 211, and then the spring 213 is squeezed so that the spring 213 presses the extrusion block 214 downward, thereby changing the force on the rotating axis of the pay-off roller 221.

[0048] When the device is used for winding, according to the tightness of the enameled wire 222 in the actual winding process, the moving block 212 is driven by the hand-screw screw 211 to move upward or downward on the four limit rods 203, and the moving block 212 acts on the spring 213 and the extrusion block 214 below it, so that the extrusion block 214 increases or decreases the extrusion force on the shaft of the pay-off roller 221 inserted into the support sleeve 201, and controls the force required for the pay-off roller 221 to rotate. When the winding device of the transformer coil is used to wind the coil, during the winding process, the enameled wire 222 is passed through the limit hole 403 at the top of the inner cylinder 402, and then the enameled wire 222 passing through the limit hole 403 is wound around the winding roller 503, and the winding roller 503 is driven to rotate by the third motor 502 for winding. When the enameled wire 222 is wound around the winding roller 503, it will circulate back and forth along the outer wall of the winding roller 503. Ring winding, when the position of the enameled wire 222 moves, the enameled wire 222 will drive the inner cylinder 402 to slide in the outer cylinder 401, so that the inner cylinder 402 reduces the obstruction to the enameled wire 222, and when the enameled wire 222 is wound on the winding roller 503, the two pneumatic rods 404 will change slightly, making it more compatible with the position of the enameled wire 222, reducing the bending and friction of the enameled wire 222 in the limiting hole 403 of the inner cylinder 402. When the enameled wire 222 is wound on the winding roller 503, the position of the enameled wire 222 on the pay-off roller 221 will also move. At this time, the first motor 301 is turned on to drive the threaded rod 302 to rotate, and the threaded rod 302 drives the moving plate 311 to move, thereby driving the winding roller 503, the outer cylinder 401 and the inner cylinder 402 on the top of the moving plate 311 to move, so that the inner cylinder 402 matches the position of the enameled wire 222 after the winding is moved.

[0049] The above description is only a preferred specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the invention according to the technical scheme and inventive concept of the invention, which should be covered by the protection scope of the invention.
