Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and in particular to a winding device for transformer manufacturing. Background Technology

[0002] The winding device for transformer production is the core equipment used to wind coils in the transformer manufacturing process. Its function is to wind the conductors into the primary and secondary coils or high-voltage / low-voltage windings of the transformer according to specific specifications and process requirements.

[0003] A search revealed that Chinese Patent CN116705502A discloses a transformer winding device, including a workbench, a winding mechanism, a drive motor, and an electro-hydraulic rod. The front of the workbench is equipped with a winding mechanism for transformer winding, on which a transformer bobbin is clamped and mounted. A drive motor is mounted on the upper surface of the workbench, and the winding mechanism drives the transformer bobbin to rotate. A mounting support is welded to the inner bottom of the workbench. This design uses the extension and retraction of the electro-hydraulic rod to drive the inner support slider to slide back and forth within the storage tank, thereby causing the first clamp and the through-hole support stand to move back and forth. This allows the first clamp to hold transformer bobbins of different specifications. Simultaneously, the front support beam slides back and forth on the outer wall of the first round rod, facilitating the reciprocating swing assembly, mounting support frame, and wire pressing assembly to be suitable for winding transformer bobbins of different specifications, thus improving applicability. However, in practical use, the above design still has the following shortcomings:

[0004] The winding device proposed in the above scheme lacks automatic clamping and unloading functions. Before winding, workers need to install the wire frame onto the machine, and after winding, they need to manually remove the wire frame. This manual loading and unloading of the wire frame significantly slows down the production pace. Before and after each batch of coils is wound, workers need to manually fix the wire frame and adjust its position. This step is time-consuming and cannot be synchronized with the continuous operation of the winding machine, resulting in frequent machine downtime and a significant decrease in overall production efficiency. Especially in large-scale production, this intermittent operation accumulates into significant time waste, limiting the production efficiency of transformers.

[0005] Therefore, it is necessary to design a winding device for transformer production to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a winding device for transformer production.

The collar and the first rotating ring are connected by a first spring.

[0013] As a preferred embodiment of the present invention, the rotating shaft, the reciprocating lead screw, and the sleeve are arranged coaxially.

[0014] As a preferred embodiment of the present invention, each of the clamping frames consists of a fixed frame and two pressure plates. The fixed frame is fixed on the movable plate, and the two pressure plates are respectively fixed at both ends of the fixed frame.

[0015] As a preferred embodiment of the present invention, the driving assembly includes a motor, the output shaft of the motor is fixed with a driving block, the driving block has a groove, a movable locking block is provided in the groove, and the locking block has an inclined surface. The locking block and the groove are connected by a second spring. The cross-section of the locking block and the sleeve are both hexagonal, and the shapes of the locking block and the sleeve are adapted to each other.

[0016] As a preferred embodiment of the present invention, a clamping assembly is provided on the frame for clamping the coil frame. The clamping assembly includes a side plate, which is fixed on the frame. A mounting ring is fixed at one end of the side plate away from the frame. An elastic pressure plate is provided on one side of the mounting ring. A second rotating ring is rotatably mounted on the side of the elastic pressure plate. The second rotating ring and the mounting ring are connected by a third spring.

[0017] As a preferred embodiment of the present invention, a first gear is fixedly sleeved on the rotating rod, the rotating rod is rotatably mounted on the side of the fixed plate through a one-way bearing, and a feeding assembly is provided on one side of the frame, the feeding assembly consisting of a feeding structure and a driving structure;

[0018] The feeding structure includes a feeding frame, a bracket fixed to the side of the feeding frame, a first shaft and a second shaft rotatably mounted on the bracket, and the first shaft and the second shaft are connected by a transmission belt. A second gear is fixedly sleeved on the first shaft, and a first gear is fixedly sleeved on the rotating rod. The first gear is positioned opposite the second gear.

[0020] As a preferred embodiment of the present invention, both the guide rod and the slider have rectangular cross-sections.

[0021] The present invention has the following beneficial effects:

[0022] 1. Through the cooperation of structures such as reciprocating screw, bevel gear, arc rack, moving cylinder, movable plate, and clamping frame, when the feeding assembly rotates to a specific position, the meshing of the bevel gear and arc rack causes the reciprocating screw to rotate and drive the moving cylinder to move, thereby causing the two movable plates to move away from or closer to each other, realizing the automatic fixing and loosening of the coil frame by the two clamping frames. No manual clamping is required, which improves production efficiency and reduces labor costs.

[0023] 2. The feeding assembly is designed, consisting of a feeding structure and a driving structure. By utilizing the sequential meshing of the driving rack with the second gear and the first gear, the feeding wheel is first driven to rotate, sending the coil frame on the feeding frame to the feeding assembly at the designated position, thus achieving automatic feeding. Then, the rotating rod is driven to rotate, causing the rotating seat and the feeding assembly to rotate. At the same time, through the cooperation of the reciprocating screw, bevel gear and arc rack, the coil frame is automatically unloaded during the rotation. The whole process has a high degree of automation, reduces manual operation, and improves production efficiency.

[0024] 3. A drive assembly is set up. Through the connection of the motor, drive block, clamping block and sleeve, the feeding assembly in the winding position is driven to rotate, so that the coil frame can rotate stably for winding. At the same time, a clamping assembly is set up. The elastic pressure plate presses the coil frame against the side of the sleeve plate under the action of the third spring, which improves the positional stability of the sleeve plate, prevents the sleeve plate from shaking during high-speed rotation, ensures smooth winding work and improves product quality.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figure 1-12A winding device for transformer production includes a frame 1. A wire feeding module 2 and a wire module 3 are provided on the frame 1. The wire feeding module 2 is used to provide cables, and the wire module 3 is used to guide the cables so that they can be evenly wound on the coil frame. The specific structure and working principle of the wire feeding module 2 and the wire module 3 are existing technologies, and the implementation method adopts conventional means. They are not shown in the figure and will not be described in detail here. A fixing plate 41 is fixed on the frame 1. A rotating rod 42 is rotatably installed on the side of the fixing plate 41. A rotating seat 43 is fixed at the end of the rotating rod 42 away from the fixing plate 41. Two connecting rods 411 are fixed on the side of the fixing plate 41. An arc-shaped rack 412 is fixed at the end of the two connecting rods 411 away from the fixing plate 41. The two arc-shaped racks 412 are arranged in a mirror image around the axis of the rotating rod 42. Four mounting seats 432 are fixed on the side of the rotating seat 43. Four L-shaped limit rods 431 are also fixed on the side of the rotating seat 43.

[0040] Four feeding components are provided on the rotating base 43 for automatic feeding and unloading of coil frames. The four feeding components are arranged in a circumferential array around the rotating rod 42. Each feeding component includes a rotating shaft 51 and a reciprocating screw 52. The rotating shaft 51 is rotatably mounted on the mounting base 432, and two opposing limit blocks 514 are fixed at the end of the rotating shaft 51 away from the mounting base 432. A groove is opened at one end of the reciprocating screw 52, ​​and two opposing limit slots 521 are opened in the groove. The end of the rotating shaft 51 away from the mounting base 432 extends into the groove, and the two limit blocks 514 slide in the two limit slots 521 respectively. The reciprocating screw 52 and the rotating shaft 51 are slidably connected, and the two limit blocks 514 and the two limit slots 521 are slidably connected. The groove 521 is configured to provide a limit for the reciprocating screw 52 and the rotating shaft 51 to prevent them from separating. In addition, when the reciprocating screw 52 rotates, it can drive the rotating shaft 51 to rotate through the two limit grooves 521 and the two limit blocks 514. A sleeve 522 is fixed at the end of the reciprocating screw 52 away from the groove. A bayonet 523 is provided on the sleeve 522. A sleeve plate 53 is rotatably installed at one end of the reciprocating screw 52. The rotating shaft 51, the reciprocating screw 52 and the sleeve plate 53 are arranged coaxially. A limit cylinder 532 is fixed on the side of the sleeve plate 53. In the initial state, the limit cylinder 532 is sleeved on the end of the limit rod 431 away from the rotating seat 43. A bevel gear 524 is fixedly sleeved on the reciprocating screw 52.

[0041] Two limiting ports 531 are provided on the sleeve plate 53. A movable cylinder 54 is threaded onto the reciprocating screw 52. Movable plates 56 are provided on both sides of the movable cylinder 54. Each movable plate 56 is connected to the movable cylinder 54 through several connecting plates 55. One end of the connecting plate 55 is rotatably connected to the outer circumferential surface of the movable cylinder 54, and the other end is rotatably connected to the movable plate 56. When the movable cylinder 54 moves, the movable cylinder 54 can drive the two movable plates 56 to move synchronously through several connecting plates 55, so that the two movable plates 56 move closer to each other or further away from each other. The ends of the two movable plates 56 slide in the two limiting ports 531 respectively. A clamping frame 57 is fixed on the side of each of the two movable plates 56. Each clamping frame 57 is composed of a fixed frame and two pressure plates. The fixed frame is fixed on the movable plate 56, and the two pressure plates are fixed at both ends of the fixed frame respectively. The shape of the pressure plates is adapted to the coil frame.

[0042] The reciprocating lead screw 52 is connected to the rotating seat 43 through a reset structure. The reset structure includes a collar 511 and a first rotating ring 512. The collar 511 is fixedly sleeved on the end of the reciprocating lead screw 52, ​​and the first rotating ring 512 is rotatably mounted on the side of the rotating seat 43. The collar 511 and the first rotating ring 512 are connected by a first spring 513. Under the elastic force of the first spring 513, the reciprocating lead screw 52 always tends to move closer to the rotating seat 43.

[0043] When the pressure plate presses down on the coil frame, the outer surface of the pressure plate fits against the coil frame, thus ensuring the pressure plate's fixation effect on the coil frame and preventing the coil frame from shaking. When the operator controls the rotating seat 43 to rotate, the rotating seat 43 can drive the four rotating shafts 51 to rotate, and the four reciprocating lead screws 52 will rotate accordingly. Figure 3As shown, for ease of understanding, the positions of the four feeding components in the initial state are marked as points a, b, c, and d, respectively. When the rotating seat 43 rotates, the four feeding components rotate clockwise. For any one of the feeding components, during its rotation from point b to point c, the bevel gear 524 on the reciprocating screw 52 will mesh with the upper-positioned arc-shaped rack 412 and rotate under the action of the arc-shaped rack 412, causing the bevel gear 524 to rotate. It should be noted that under the limiting action of the limiting rod 431 and the limiting cylinder 532, the sleeve 53 cannot rotate with the reciprocating screw 52. When the sleeve 53 cannot rotate, the two... The limiting port 531 provides a constraint for the two movable plates 56, which are connected to the moving cylinder 54 through several connecting plates 55. This prevents the moving cylinder 54 from rotating with the reciprocating screw 52. Therefore, during the process of the feeding assembly rotating from point b to point c, the reciprocating screw 52 rotates, driving the moving cylinder 54 to move along the reciprocating screw 52. When the moving cylinder 54 moves, it can drive the two movable plates 56 to move away from each other through several connecting plates 55, thereby causing the two clamping frames 57 to move away from each other. Finally, the two clamping frames 57 jointly press the coil frame sleeved on it, which plays a role in fixing the coil frame. This design realizes the automatic fixing of the coil frame without the need for manual clamping.

[0044] Conversely, during the process of the feeding assembly rotating from point c to point d, the bevel gear 524 will mesh with the lower-positioned arc-shaped rack 412 and rotate. It should be noted that during the process of the bevel gear 524 meshing with the upper-positioned arc-shaped rack 412, the moving cylinder 54 has already moved to the end position of the reciprocating screw 52. Therefore, when the reciprocating screw 52 continues to rotate, it can drive the moving cylinder 54 to move in the opposite direction, so that the moving cylinder 54 returns to its initial position. According to the above principle, it can be understood that when the moving cylinder 54 returns to its initial position, the two movable plates 56 can drive the two clamping frames 57 to move closer to each other. This makes the two clamping frames 57 no longer support the coil frame together. When the feeding assembly rotates to point d, the two clamping frames 57 return to their initial position (i.e., the state of moving closer to each other). At this time, without the clamping effect of the two clamping frames 57, the coil frame falls naturally under the action of gravity, realizing automatic feeding.

[0045] A drive assembly is mounted on the frame 1. The drive assembly includes a motor 61, and a drive block 62 is fixed to the output shaft of the motor 61. A groove 63 is formed on the drive block 62, and a movable locking block 64 is disposed within the groove 63. The locking block 64 has an inclined surface. The locking block 64 and the groove 63 are connected by a second spring 65. The cross-sections of the locking block 64 and the sleeve 522 are both hexagonal, and the shapes of the locking block 64 and the sleeve 522 are adapted to each other. When the locking block 64 is engaged in the sleeve 522, the side of the locking block 64 fits against the inner surface of the sleeve 522. When the feeding assembly rotates to position c, the sleeve 522 is exactly aligned with the drive block 62. At this time, the operator pulls the sleeve plate 53, causing the sleeve plate 53 to drive the reciprocating screw 52 to move horizontally. The sleeve 522 moves accordingly until it is fitted onto the drive block 62. During this process, the sleeve 522 will press against the inclined surface of the locking block 64. When the locking block 64 is pressed, it retracts into the recess 63. When the locking slot 523 on the sleeve 522 moves to the position directly opposite the locking block 64, the locking block 64 pops out of the recess 63 under the action of the second spring 65 and locks into the locking slot 523. At this time, the locking block 64 connects the sleeve 522 and the drive block 62, allowing the drive block 62 to drive the sleeve 522 to rotate, forming a... Figure 6 In the state shown, the feeding component at point c is positioned directly opposite the wire module 3 for easy winding. During winding, the operator first secures the cable to one end of the coil frame, then starts the motor 61. It should be noted that since the sleeve 53 has moved away from the rotating seat 43, the limiting cylinder 532 will also move away from the rotating seat 43. When the sleeve 522 is connected to the drive block 62, the limiting cylinder 532 will separate from the limiting rod 431. At this point, the limiting rod 431 and the limiting cylinder 532... No longer providing a limit for the sleeve 53, in this case, when the motor 61 runs, it drives the sleeve 522 to rotate, and the reciprocating screw 52 rotates accordingly. When the reciprocating screw 52 rotates, it can drive the moving cylinder 54 to rotate under the action of friction, and finally make the sleeve 53 rotate accordingly. Through this design, the motion interference between the sleeve 53 and the reciprocating screw 52 can be avoided, so that the two clamping frames 57 can drive the coil frame to rotate. The coil frame is wound during the rotation. During the winding process, the wire module 3 runs, so that the cable is evenly wound on the coil frame.

[0046] A clamping assembly is provided on the frame 1 for clamping the coil frame. The clamping assembly includes a side plate 71, which is fixed to the frame 1. A mounting ring 72 is fixed to the end of the side plate 71 away from the frame 1. An elastic pressure plate 73 is provided on one side of the mounting ring 72. A second rotating ring 74 is rotatably mounted on the side of the elastic pressure plate 73. The second rotating ring 74 is connected to the mounting ring 72 by a third spring 75. Figure 6As shown, during the connection between the sleeve 522 and the drive block 62, the coil frame on the feeding assembly first contacts the elastic pressure plate 73 and pushes the elastic pressure plate 73 to move. Under the elastic force of the third spring 75, the elastic pressure plate 73 can press the coil frame tightly against the side of the sleeve 53, thereby improving the positional stability of the sleeve 53 and preventing the sleeve 53 from shaking during high-speed rotation. When the coil frame rotates, it can drive the elastic pressure plate 73 to rotate through friction. The setting of the second rotating plate allows the elastic pressure plate 73 and the third spring 75 to rotate relative to each other, ensuring the smooth operation of the device.

[0047] In use, the operator places the coil frame onto the feeding assembly located at point a. The feeding of the coil frame can be done manually or automatically. Therefore, this invention designs a feeding assembly, which is arranged on one side of the frame 1. The feeding assembly consists of a feeding structure and a driving structure. The feeding structure includes a feeding frame 81, with a bracket 82 fixed to its side. A first shaft 83 and a second shaft 84 are rotatably mounted on the bracket 82, and are connected by a transmission belt 85. A second gear 831 is fixedly mounted on the first shaft 83, and a first gear 421 is fixedly mounted on the rotating rod 42, with the first gear 421 facing the second gear 831. A feeding wheel 841 is fixedly mounted on the second shaft 84, with the feeding wheel 841 facing the feeding frame 81. Before winding, the operator can place the coil frame sequentially onto the feeding frame 81, forming... Figure 1 As shown, for the coil frame located below the feeding wheel 841, the outer circumferential surface of the feeding wheel 841 is in contact with the top surface of the coil frame. The driving structure includes a guide rod 91, with fixed rods 922 fixed at both ends of the guide rod 91. One fixed rod 922 is fixedly connected to the feeding frame 81, and the other fixed rod 922 is fixedly connected to the fixed plate 41. A slider 92 is slidably sleeved on the guide rod 91, and both the guide rod 91 and the slider 92 have rectangular cross sections to prevent the slider 92 from shaking on the guide rod 91. Limiting protrusions 921 are fixed at both ends of the guide rod 91 to provide limits for the slider 92. A driving rack 93 is fixed on the top surface of the slider 92, and the driving rack 93 is set opposite to the second gear 831 and the first gear 421. A pull rod 94 is fixed on the side of the slider 92, and the operator can pull the slider 92 to move it through the pull rod 94.

[0048] When it is necessary to control the rotation of the rotating seat 43 and the four feeding components, the operator can pull the lever 94. When the lever 94 moves, it drives the slider 92 to move, and the drive rack 93 on the slider 92 moves accordingly. During the movement, the drive rack 93 first meshes with the second gear 831 and drives the second gear 831 to rotate. When the second gear 831 rotates, it drives the first shaft 83 to rotate. The first shaft 83 can drive the second shaft 84 to rotate through the transmission belt 85, causing the feeding wheel 841 to rotate. During the rotation, the feeding wheel 841 can use friction to drive the coil frame below it to move, so that the coil frame moves from the feeding frame 81 to the feeding component located at point a, thereby realizing automatic feeding of the coil frame. Furthermore, after the drive rack 93 separates from the second gear 831, it will mesh with the first gear 421 and drive the rotating rod 42 to rotate. During the meshing process of the first gear 421, the first gear 421 rotates exactly 90°, which causes the rotating rod 42 and the rotating seat 43 to rotate exactly 90°, realizing the automatic rotation of the four feeding components. In summary, during the production of transformers, the feeding, clamping and unloading of the coil frame are all automated, which not only reduces the workload of the workers, but also improves the production efficiency of the device. It is worth noting that the rotating rod 42 and the fixed plate 41 are connected by a one-way bearing, and the second gear 831 and the first shaft 83 are also connected by a one-way bearing. This ensures that the drive rack 93 will not drive the rotating rod 42 and the first shaft 83 to rotate in opposite directions during the reset process, so that the rotating rod 42 and the first shaft 83 always rotate in one direction. The specific structure and working principle of the one-way bearing are existing technologies, and the implementation method adopts conventional means, which are not shown in the figure and will not be described in detail here.

[0049] The specific working principle of this invention is as follows:

[0050] When the winding device for transformer production is in operation, the coil frames are first loaded. The operator places the coil frames sequentially on the feeding rack 81, then pulls the lever 94. The lever 94 moves the slider 92. The drive rack 93 on the slider 92 first meshes with the second gear 831, driving the second gear 831 to rotate. The second gear 831 drives the first shaft 83 to rotate, which in turn drives the second shaft 84 to rotate via the transmission belt 85. This, in turn, causes the feeding wheel 841 to rotate. The feeding wheel 841 uses friction to rotate the feeding rack 81. The lower coil frame moves to the feeding component at point a to achieve automatic feeding. After the drive rack 93 separates from the second gear 831, it continues to move and meshes with the first gear 421, driving the first gear 421 to rotate 90°. Since the first gear 421 is fixed on the rotating rod 42, and the rotating rod 42 is connected to the fixed plate 41 through a one-way bearing, the rotating rod 42 drives the rotating seat 43 to rotate 90°, causing the four feeding components to rotate clockwise. At the same time, the one-way bearing ensures that the rotating rod 42 will not rotate in the opposite direction when the drive rack 93 is reset.

[0051] During the process of the feeding assembly rotating from point b to point c, the bevel gear 524 on the reciprocating screw 52 meshes with the upper-positioned arc rack 412. Under the action of the arc rack 412, the bevel gear 524 drives the reciprocating screw 52 to rotate. Due to the limitation of the limiting rod 431 and the limiting cylinder 532, the sleeve 53 cannot rotate. The limiting port 531 on the sleeve 53 constrains the movable plate 56. The movable plate 56 is connected to the moving cylinder 54 through the connecting plate 55. The moving cylinder 54 cannot rotate, so the reciprocating screw 52 rotates to drive the moving cylinder 54 to move along it. The moving cylinder 54 drives the two movable plates 56 to move away from each other through the connecting plate 55, so that the two clamping frames 57 move away from each other and jointly press the coil frame sleeved on it to achieve automatic fixing.

[0052] When the feeding assembly rotates to position c, the sleeve 522 is directly opposite the drive block 62. The operator pulls the sleeve plate 53, causing the sleeve 522 to fit onto the drive block 62. The sleeve 522 presses against the inclined surface of the locking block 64, causing the locking block 64 to retract into the recess 63. When the locking slot 523 on the sleeve 522 is aligned with the locking block 64, the locking block 64 pops out under the action of the second spring 65 and engages with the locking slot 523, connecting the sleeve 522 and the drive block 62. At this time, the coil frame on the feeding assembly contacts the elastic pressure plate 73 and pushes it to move. Under the elastic force of the third spring 75, the elastic pressure plate 73 pushes the coil frame... Pressing the sleeve 53 against the side improves the positional stability of the sleeve 53. Then, the motor 61 is started, and the motor 61 drives the drive block 62 to rotate, which in turn drives the sleeve 522 and the reciprocating screw 52 to rotate. Since the sleeve 53 has moved away from the rotating seat 43, the limiting cylinder 532 separates from the limiting rod 431. When the reciprocating screw 52 rotates, it drives the moving cylinder 54 to rotate under the action of friction, which finally makes the sleeve 53 rotate, avoiding interference between the movement of the sleeve 53 and the reciprocating screw 52. The two clamping frames 57 drive the coil frame to rotate for winding. At the same time, the wire module 3 runs to make the cable evenly wound on the coil frame.

[0053] After the winding is completed, during the process of the feeding assembly rotating from point c to point d, the bevel gear 524 meshes with the lower-positioned arc-shaped rack 412 and rotates. Since the moving cylinder 54 has already moved to the end position of the reciprocating screw 52, ​​the reciprocating screw 52 continues to rotate, driving the moving cylinder 54 to move in the opposite direction and reset. This causes the two movable plates 56 to move closer to each other, so that the two clamping frames 57 no longer support the coil frame together. When the feeding assembly rotates to point d, the two clamping frames 57 reset to their initial close-to-each-other state, and the coil frame falls naturally under the action of gravity, realizing automatic unloading. This cycle is repeated to realize the automated continuous production of coil frame feeding, clamping, winding, and unloading in transformer production.
