TECHNICAL FIELD

[0001] The present application relates to the technical field of transformers, in particular to a winding device for small transformer winding. BACKGROUND

[0002] As a key component, small transformers play an important role in voltage conversion and electrical isolation in various electronic devices. The winding, as the core part of the small transformer, directly affects the performance and stability of the transformer. Although partially automated winding devices improve production efficiency to some extent, they lack flexibility, such as difficulty in controlling tension. The main problems are as follows: 1. It is difficult to flexibly control the tension during winding, so it is not possible to accurately adjust the tension according to the characteristics of the enameled wire, resulting in excessive or insufficient tension during winding. Excessive tension can easily thin or even break the wire, and insufficient tension can cause the winding to be unable to arrange closely during winding, resulting in a loose overall structure of the winding. The loose winding increases the magnetic flux leakage, reduces the efficiency of the transformer, and affects its service life. In addition, the contact surface between the enameled wire and the winding or tension adjusting mechanism moves relatively during winding, causing a certain angle deviation of the enameled wire relative to the winding, resulting in a large friction force that can damage the enameled wire coating, reduce the insulation performance, and increase the risk of short circuit of the winding.

[0003] 2. The clamping assembly of the winding device does not have a double clamping effect, resulting in poor stability of the winding during rotation, easy slippage during rotation, and difficulty in timely detection of slippage. Slippage can cause inaccurate number of turns of the winding, and changes in the number of turns can directly affect the electrical parameters of the winding and the normal operation of the transformer.

[0015] The technical scheme provided by the application has at least the following technical effects or advantages: 1. By employing a tension adjustment component, the problem of existing winding equipment's inability to flexibly control the tension during winding is effectively solved. This prevents precise tension adjustment based on the characteristics of the enameled wire, leading to either excessive or insufficient tension during winding. Excessive tension can thin or even break the wire, while insufficient tension prevents the winding from being tightly aligned, resulting in a loose overall winding structure. Loose windings increase leakage flux, reduce transformer efficiency, and affect its service life. Furthermore, the relative movement between the enameled wire and the contact surface of the winding or tension adjustment mechanism during winding causes a certain angle of deviation between the enameled wire and the winding. Excessive tension during winding can generate significant friction, damaging the enamel coating of the wire, leading to decreased insulation performance and increased risk of short circuits. This invention addresses this by using a tension adjustment component to regulate the winding tension. It precisely adjusts the tension based on the characteristics of the enamel wire, preventing excessive tension that could thin or break the wire, while also preventing insufficient tension, ensuring a tighter winding arrangement and extending the transformer's lifespan. Furthermore, it corrects excessive wire feed during winding, preventing excessive friction between the wire and the winding or tension adjustment mechanism, thus reducing the risk of short circuits later on.

[0016] 2. By employing a winding assembly, this invention effectively solves the problem that existing winding equipment lacks a dual-clamping effect in its clamping components, resulting in poor stability during winding rotation. This leads to slippage during rotation, which is difficult to detect promptly. Slippage causes inaccurate winding turn counts, directly affecting the electrical parameters of the winding and impacting the normal operation of the transformer. This invention provides dual clamping of the winding through the winding assembly, improving its stability during rotation. Simultaneously, it issues a timely alarm when winding slippage occurs, reminding staff to maintain the equipment, ensuring accurate winding turn counts, and preventing the production of substandard products.

[0019] For applications where it is difficult to flexibly control the tension during winding, this invention uses a tension adjustment component to precisely adjust the tension according to the characteristics of the enameled wire, avoiding improper tension and ensuring a tight winding arrangement. For applications lacking a double clamping effect, this invention uses a winding component to double-clamp the winding, improving the stability of the winding during rotation. At the same time, it issues an alarm in a timely manner when the winding slips, reminding staff to maintain the equipment and ensuring the accuracy of the number of turns in the winding.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example

[0022] Please see Figure 1 As shown, a small transformer winding device includes a base 1, a fixed frame 2, and a winding drum 3. The fixed frame 2 is fixedly installed on the upper surface of the base 1, and the winding drum 3 is rotatably connected to the inner wall of the fixed frame 2. Enamelled wire is wound on the outer surface of the winding drum 3. A tension adjusting component 4 is provided in the middle of the upper surface of the base 1, and a winding component 5 is fixedly installed on the upper surface of the base 1. The inner wall of the winding component 5 clamps the winding workpiece 6. When winding the enamelled wire on the winding drum 3 to the winding workpiece 6, the end of the enamelled wire is first fixedly wound onto the winding workpiece 6. The winding component 5 drives the winding workpiece 6 to rotate, causing the winding drum 3 to rotate on the fixed frame 2. The tension of the enamelled wire wound on the winding workpiece 6 is adjusted by the tension adjusting component 4. With the stable clamping of the winding component 5, the number of turns of the winding workpiece 6 is stable during winding, and the enamelled wire is tightly attached to the winding workpiece 6.

[0023] Please see Figure 2 and Figure 3As shown, the tension adjustment assembly 4 includes a support plate 41, a first threaded rod 42 rotatably connected to the inner cavity of the support plate 41, a first motor 43 disposed on the outer surface of the support plate 41, a moving block 44 slidably connected to the inner cavity of the support plate 41, a connecting block 45 fixedly mounted on the upper surface of the moving block 44, a correction mechanism 46 disposed on the side of the connecting block 45 near the fixing frame 2, an adjustment mechanism 47 disposed on the side of the connecting block 45 away from the correction mechanism 46, a buffer mechanism 48 disposed on the upper surface of the connecting block 45, an alarm mechanism 49 disposed on one side of the buffer mechanism 48, a first limit wheel 410 fixedly mounted on the upper surface of the connecting block 45, and an adjustment mechanism. The bottom end of 47 is provided with a second limiting wheel 411. A guide rod 412 is rotatably connected to the middle inner wall of the connecting block 45. The support plate 41 and the base 1 are fixedly connected. The output end of the first motor 43 is sleeved with the first threaded rod 42. The moving block 44 and the first threaded rod 42 are connected by threads. The first limiting wheel 410 is composed of a first support frame and a first rotating wheel. The first support frame and the connecting block 45 are fixedly connected. The first rotating wheel and the first support frame are rotatably connected. The second limiting wheel 411 is composed of a second support frame and a second rotating wheel. The second rotating wheel and the second support frame are rotatably connected. There are two guide rods 412. When the tension is adjusted by the tension adjusting component 4, the guide rod 412 is used to adjust the tension. The enameled wire on the winding spool 3 passes through the straightening mechanism 46. The straightening mechanism 46 controls the angle of the enameled wire to reduce the friction between the enameled wire and the equipment. The operation of the first motor 43 drives the first threaded rod 42 to rotate. The rotation of the first threaded rod 42 causes the moving block 44 to move on the outer surface of the support plate 41. The movement of the moving block 44 causes the connecting block 45 to move, so that when the winding processing part 6 is wound, the connecting block 45 drives the enameled wire to be evenly wound on the outer surface of the winding processing part 6. The adjusting mechanism 47 is used to adjust the tension of the enameled wire, and the buffering mechanism 48 is used to flexibly limit the enameled wire to prevent the enameled wire from becoming too thin due to excessive tension. The breakage alarm mechanism 49 is used to issue an alarm when the tension fluctuates greatly. During winding, the enameled wire passes through the straightening mechanism 46 and the upper end of the first limiting wheel 410, then passes between two guide rods 412. The guide rods 412 are used to guide the enameled wire between the first limiting wheel 410 and the second limiting wheel 411. Finally, it passes through the bottom end of the second limiting wheel 411 to connect the enameled wire to the winding processing part 6. The second limiting wheel 411 is used to provide tension to the enameled wire to achieve flexible adjustment of the enameled wire. The winding assembly 5 drives the winding processing part 6 to rotate and cooperates with the movement of the connecting block 45 to make the enameled wire evenly wound on the outer surface of the winding processing part 6.

[0024] Please see Figure 3 and Figure 5As shown, the correction mechanism 46 includes a fixing bar 461, which is fixedly connected to a connecting block 45. A cleaning brush 462 is slidably connected to the inner wall of the fixing bar 461. The cleaning brush 462 can be adjusted by external force to move on the inner wall of the fixing bar 461, so that the enameled wire passes through the cleaning brush 462 when passing through the floating ring 465 and the first limiting wheel 410. In this way, the cleaning brush 462 can clean the enameled wire and improve the cleanliness of the enameled wire during winding. A limiting ring 463 is fixedly installed on the side of the fixing bar 461 away from the connecting block 45. A groove 464 is opened on the outer surface of the limiting ring 463. A floating ring 465 is provided in the middle part of the limiting ring 463. The inner cavity of the floating ring 465 A ball 466 is connected to the movable connection. A first slide rod 467 is fixedly installed on the outer surface of the floating ring 465. A first spring 468 is sleeved on the outer surface of the first slide rod 467. A washer 469 is slidably connected to the outer surface of the first slide rod 467. The first slide rod 467 and the slide groove 464 are slidably connected. The first spring 468 is located between the floating ring 465 and the washer 469. The washer 469 is slidably connected to the inner wall of the limiting ring 463. The washer 469 is used to prevent friction between the first spring 468 and the limiting ring 463. The outer surface of the cleaning brush 462 is provided with bristles for cleaning the enameled wire. The bristles are aligned with the middle of the floating ring 465. The connecting block 45 is on the support plate 41. When the winding component 6 is wound, the moving connecting block 45 and the winding component 6 cooperate to evenly wind the winding component 6. At this time, the enameled wire on the winding drum 3 and the connecting block 45 have a certain angular deviation. The angle of the enameled wire is corrected and buffered by the straightening mechanism 46. The enameled wire on the winding drum 3 passes through the floating rings 465. The ball 466 is used to assist the enameled wire in moving in the inner cavity of the floating ring 465, reducing the friction between the floating ring 465 and the enameled wire. When there is a certain angular offset between the enameled wire and the floating ring 465, the floating ring 465 drives the first sliding rod 467 to slide in the inner cavity of the slide groove 464. At this time, the floating ring 465 is in the limiting ring 463. The inner cavity floats and compresses the first spring 468. Under the elastic force of the first spring 468, the floating ring 465 can flexibly limit the enameled wire, preventing the enameled wire that has deviated on the winding drum 3 from generating large friction with the floating ring 465, reducing the deviation of the enameled wire relative to the equipment angle, reducing the friction between the enameled wire and the equipment, preventing damage to the enameled wire enamel film, and reducing the risk of short circuits in the later use of the winding processing part 6. The cleaning brush 462 on the fixing bar 461 is used to clean the enameled wire. After cleaning, the surface of the enameled wire is clean, which can improve the tightness and neatness of the wound winding structure, improve electrical performance and stability, reduce the occurrence of faults, and thus ensure the safe and reliable operation of the power system.

[0025] Please see Figure 4 and Figure 6As shown, the adjustment mechanism 47 includes an adjustment block 471. A second threaded rod 472 is rotatably connected to the inner cavity of the adjustment block 471. A slider 473 is slidably connected to the outer surface of the adjustment block 471. The slider 473 and the second threaded rod 472 are connected by a thread. A drive rod 474 is fixedly installed on the outer surface of the slider 473. A storage rod 475 is fixedly installed at the four corners of the lower surface of the adjustment block 471. A lifting rod 476 is slidably connected to the inner cavity of the storage rod 475. A lifting block 477 is fixedly installed on the lower surface of the lifting rod 476. A drive rod 477 is opened on the outer surface of the lifting block 477. A pressure rod 479 is fixedly installed on the lower surface of the groove 478 and the lifting block 477. A sleeve rod 4710 is slidably connected to the outer surface of the pressure rod 479. A second spring 4711 is provided in the inner cavity of the sleeve rod 4710. The inner cavities of the adjusting block 471 and the connecting block 45 are slidably connected. The drive rod 474 and the drive groove 478 are slidably connected. The sleeve rod 4710 and the second limiting wheel 411 are fixedly connected. The second spring 4711 is located between the pressure rod 479 and the second limiting wheel 411. The adjusting mechanism 47 is used to adjust the tension of the second limiting wheel 411 on the enameled wire. When adjusting the tension of 411, rotating the second threaded rod 472 causes the slider 473 to slide on the outer surface of the adjusting block 471. The sliding of the slider 473 causes the drive rod 474 to slide in the inner cavity of the drive groove 478. At this time, the lifting rod 476 slides in the inner cavity of the receiving rod 475 and causes the lifting block 477 to move. The movement of the lifting block 477 causes the pressure rod 479 to move. The movement of the pressure rod 479 causes the pressure rod 479 to compress the second spring 4711 and cause the sleeve rod 4710 to move. The movement of the sleeve rod 4710 causes the second limit wheel 411 to rise. The tension changes, thus changing the compressive force on the enameled wire as it passes through the second limiting wheel 411, thereby adjusting the tension of the enameled wire and ensuring that the winding workpiece 6 has appropriate tension during winding. At the same time, the second limiting wheel 411 is flexibly fixed on the adjusting mechanism 47. When the tension on the second limiting wheel 411 is too high, the pressure rod 479 slides in the inner cavity of the sleeve rod 4710 and compresses the second spring 4711. The elastic force of the second spring 4711 gives the second limiting wheel 411 a certain buffering effect in the vertical direction, preventing the enameled wire from breaking due to high tension during winding.

[0026] Please see Figure 4 , Figure 7 and Figure 8As shown, the buffer mechanism 48 includes a first fixed block 481, a third threaded rod 482 rotatably connected to the inner cavity of the first fixed block 481, and a first pressing block 483 slidably connected to the inner cavities of both ends of the first fixed block 481.

Between the punch blocks 484, the first fixing block 481 and the connecting block 45 are fixedly connected. A pressing rod 487 is fixedly installed on the outer surface of the buffer block 484. The buffer block 484 and the adjusting block 471 are fixedly connected. The alarm mechanism 49 includes an alarm frame 491.

A connecting rod 496 is fixedly installed in the middle part of the first protrusion 495. The outer surface of the alarm frame 491 is provided with a first button 497, which is aligned with the connecting rod 496. There are two first buttons 497, and both are electrically connected to the first alarm 492. Pressing the first button 497 controls the first alarm 492 to sound an alarm. The ends of the pressing rod 487 and the first protrusion 495 are flush, so that the pressing rod 487 can press the first protrusion 495 when it moves a large distance. There are two first protrusions 495, and the pressing rod 487 is located between the two first protrusions 495. The buffer mechanism 48 can buffer the tension of the enameled wire in the front-back direction. When the tension on the second limit wheel 411 is large, it drives the adjustment mechanism 47 to move. The movement of the first fixed block 481 causes the second sliding rod 485 to slide within the first fixed block 481, compressing the third spring 486. The elastic force of the third spring 486 then buffers the tension of the enameled wire in the front-to-back direction. Combined with the elastic force of the second spring 4711, this provides a buffering effect during winding of the winding component 6. This provides tension to ensure the enameled wire is evenly and tightly distributed on the winding component 6, while preventing excessive tension from causing the wire to break. Rotating the third threaded rod 482 causes the first pressing block 483 to slide within the first fixed block 481, changing the distance between the first pressing block 483 and the buffer block 484, thus changing the degree of compression on the third spring 486.The pressure exerted by the third spring 486 on the buffer block 484 can be adjusted to improve the stability of the buffer block 484. Furthermore, when the buffer block 484 exhibits a large amplitude, it indicates that the tension of the enameled wire during winding is unstable. In this case, the movement of the buffer block 484 causes the compression rod 487 to compress the first protrusion 495. This compression causes the first protrusion 495 to slide on the limit rod 493 and compress the fourth spring 494, causing the connecting rod 496 to compress the first button 497. Pressing the first button 497 triggers the first alarm 492 to sound, thus reminding personnel that equipment maintenance is required.

[0027] Example

[0028] Please see Figure 1 and Figure 9 As shown, the winding assembly 5 includes a base plate 51, a fourth threaded rod is provided in the inner cavity of the base plate 51, a third motor is provided in the inner cavity of the base plate 51, the output end of the third motor is sleeved with the fourth threaded rod, a clamping plate 52 is slidably connected in the inner cavity of the base plate 51, the clamping plate 52 and the fourth threaded rod are connected by threads, and the threads at both ends of the fourth threaded rod are opposite in direction, a second motor 53 is provided on the outer surface of the clamping plate 52, and a clamping mechanism 54 is provided on the inner wall of the clamping plate 52. The third motor drives the fourth threaded rod to rotate, and the rotation of the fourth threaded rod causes the clamping plate 52 to slide on the base plate 51, so that the clamping mechanism 54 clamps and fixes the winding workpiece 6. The second motor 53 is used to drive one of the clamping mechanisms 54 to rotate, thereby driving the winding workpiece 6 to rotate to facilitate the winding of the winding workpiece 6.

[0029] Please see Figure 9 and Figure 10As shown, the clamping mechanism 54 includes a rotating disk 541. There are two clamping mechanisms 54. The rotating disk 541 and the clamping plate 52 are rotatably connected. The output end of the second motor 53 is sleeved with one of the rotating disks 541. A clamping disk 542 is fixedly connected to the end of the rotating disk 541 away from the clamping plate 52. The clamping disk 542 and the two ends of the winding workpiece 6 are in close contact. A flexible limiting mechanism 543 is slidably connected to the inner cavity of the clamping disk 542. A connecting frame 545 is fixedly installed on the outer surface of the clamping disk 542. A positioning mechanism 544 is provided on the outer surface of the connecting frame 545. When clamping the winding workpiece 6, the clamping disk 542 and the two sides of the winding workpiece 6 are tightly connected. The clamping plate 542 is rigidly limited by a close contact mechanism, while the flexible limiting mechanism 543 is used to flexibly fix the winding workpiece 6, thus achieving double fixation of the winding workpiece 6. The positioning mechanism 544 on the connecting frame 545 is used to limit the flexible limiting mechanism 543. When the winding workpiece 6 rotates, it drives the flexible limiting mechanism 543 to slide in the inner cavity of the clamping plate 542. At this time, the flexible limiting mechanism 543 moves relative to the positioning mechanism 544 and generates pressure, causing the positioning mechanism 544 to issue an alarm, reminding the staff that the winding workpiece 6 is slipping and needs to be maintained to ensure that the wound winding workpiece 6 meets the usage requirements.

[0030] Please see Figure 10 , Figure 11 and Figure 12As shown, the flexible limiting mechanism 543 includes a clamping block 5431. Second protrusions 5432 are fixedly installed on both sides of the clamping block 5431. A flexible block 5433 is slidably connected to the inner cavity of the clamping block 5431. Anti-slip textures are formed on the outer surface of the flexible block 5433 to improve the stability of the flexible block 5433 and the winding workpiece 6 during clamping. A spring rod 5434 is fixedly installed on the outer surface of the flexible block 5433. The spring rod 5434 is slidably connected to the clamping block 5431. A fifth spring 5435 is sleeved on the outer surface of the spring rod 5434. A positioning groove 5436 is formed in the middle of the clamping block 5431. The fifth spring 5435 is located between the inner wall of the clamping block 5431 and the flexible block 5433. There are [missing information - likely related to a distance between the clamping block 5431 and the inner walls of the clamping disc 542]. The gap is such that the second protrusion 5432 and the clamping disk 542 are slidably connected, and the clamping block 5431 and the clamping disk 542 are slidably connected. The outer surfaces of the clamping disk 542 and the clamping block 5431 near the winding workpiece 6 are flush. Thus, when not in contact with the winding workpiece 6, the flexible block 5433 protrudes from the outside of the clamping disk 542 and the clamping block 5431. When clamping the winding workpiece 6, the flexible block 5433 first contacts the winding workpiece 6 to form a flexible clamping. The positioning mechanism 544 includes a positioning block 5441. A positioning rod 5442 is slidably connected to the inner cavity of the positioning block 5441. A positioning ball 5443 is movably connected to one end of the positioning rod 5442. A sixth spring 5444 is sleeved on one end of the positioning rod 5442. The outer surface of the positioning rod 5442 is fixed. A second pressing block 5445 is fixedly installed, and the second pressing block 5445 and the positioning block 5441 are slidably connected. A second button 5446 is provided on the outer surface of the positioning block 5441, and a second alarm 5447 is fixedly installed on the outer surface of the positioning block 5441. The second button 5446 and the second alarm 5447 are electrically connected, and pressing the second button 5446 controls the second alarm 5447 to sound an alarm. A sixth spring 5444 is located between the inner wall of the positioning block 5441 and the second pressing block 5445. The positioning block 5441 and the connecting bracket 545 are fixedly connected, and the positioning ball 5443 and the positioning groove 5436 are engaged. There is a gap between the second pressing block 5445 and the second button 5446, and the positioning ball 5443 is in contact with the outer surface of the clamping block 5431. When the second pressing block 5445 and the second button 5446 contact and press, and the clamping plate 542 and the flexible limiting mechanism 543 clamp the winding workpiece 6, the flexible block 5433 first contacts the winding workpiece 6, causing the flexible block 5433 to slide in the inner cavity of the clamping block 5431. At this time, the spring rod 5434 slides in the inner cavity of the clamping block 5431 and presses the fifth spring 5435. This ensures that when the clamping plate 542 slips, the flexible block 5433 and the outer surface of the winding workpiece 6 still maintain stable contact. Thus, when the winding workpiece 6 slips on the outer surface of the clamping plate 542 during winding, it drives the flexible block 5433 to slide. The sliding of the flexible block 5433 drives the clamping block 5431 and the second protrusion 5432 to slide in the inner cavity of the clamping plate 542.At this point, the positioning ball 5443 and the positioning groove 5436 disengage, causing the positioning ball 5443 to contact the outer surface of the clamping block 5431. This causes the positioning rod 5442 to slide within the inner cavity of the positioning block 5441, compressing the sixth spring 5444. The sliding of the positioning rod 5442 causes the second pressing block 5445 to compress the second button 5446, triggering the second alarm 5447 to sound an alarm. This alerts the staff to maintain the equipment, ensuring the accuracy of the number of turns in the winding processing part 6 and preventing the production of substandard products.

[0031] In summary, when winding the enameled wire on the winding drum 3 onto the winding workpiece 6, the end of the enameled wire is first fixedly wound onto the winding workpiece 6. The winding assembly 5 drives the winding workpiece 6 to rotate, causing the winding drum 3 to rotate on the fixing frame 2. The tension of the enameled wire wound on the winding workpiece 6 is adjusted by the tension adjusting assembly 4. The stable clamping of the winding assembly 5 ensures a stable number of turns on the winding workpiece 6 during winding, while simultaneously ensuring the enameled wire is tightly adhered to the winding workpiece 6. When adjusting the tension using the tension adjusting assembly 4, the winding drum... The enameled wire on the 3-axis passes through the straightening mechanism 46. The straightening mechanism 46 controls the angle of the enameled wire to reduce the friction between the enameled wire and the equipment. The operation of the first motor 43 drives the first threaded rod 42 to rotate. The rotation of the first threaded rod 42 drives the moving block 44 to move on the outer surface of the support plate 41. The movement of the moving block 44 drives the connecting block 45 to move, so that when the winding processing part 6 is wound, the connecting block 45 drives the enameled wire to be evenly wound on the outer surface of the winding processing part 6. The adjusting mechanism 47 is used to adjust the tension of the enameled wire and slow down the winding process. The punching mechanism 48 is used to flexibly limit the enameled wire to prevent excessive tension from causing the wire to thin or break. The alarm mechanism 49 is used to issue an alarm when the tension fluctuates significantly. During winding, the enameled wire passes through the straightening mechanism 46 and the upper end of the first limiting wheel 410, then passes between two guide rods 412. The guide rods 412 guide the enameled wire between the first limiting wheel 410 and the second limiting wheel 411. Finally, it passes through the bottom end of the second limiting wheel 411 to connect the enameled wire to the winding processing part 6. The second limiting wheel 411 is used for... Tension is applied to the enameled wire to achieve flexible adjustment of the enameled wire. The winding assembly 5 drives the winding processing part 6 to rotate and cooperates with the movement of the connecting block 45, so that the enameled wire is evenly wound on the outer surface of the winding processing part 6. The third motor drives the fourth threaded rod to rotate, and the rotation of the fourth threaded rod causes the clamping plate 52 to slide on the base plate 51, so that the clamping mechanism 54 clamps and fixes the winding processing part 6. The second motor 53 is used to drive one of the clamping mechanisms 54 to rotate, thereby driving the winding processing part 6 to rotate to facilitate the winding of the winding processing part 6.
