Description

A coil assembly device and method for transformer processing Technical Field

[0001] This invention relates to the field of transformer processing technology, specifically to a coil assembly device and method for transformer processing. Background Technology

[0002] Currently, most transformer coil assembly operations are performed manually with the aid of simple tools. Its core function is to assemble the coils onto the core rods, completing the transformer winding and core assembly process. This provides a fundamental guarantee for the transformer's insulation performance and operational stability, making it an indispensable and crucial assembly step in transformer manufacturing.

[0003] Existing coil assembly methods have significant drawbacks: during manual operation, it is difficult to ensure stable and coaxial assembly of the coil and core column, easily causing scratches and damage to the coil insulation layer; furthermore, the lack of a precise positioning mechanism leads to insufficient assembly accuracy between the winding and the core; simultaneously, manual operation is labor-intensive, has low work efficiency, and cannot flexibly adapt to the coil assembly requirements of transformers with different capacities. These problems not only compromise the integrity of the coil insulation structure, affecting the operational stability and service life of the transformer, but also increase safety hazards associated with manual operation, restrict production progress, and fail to meet the standardized and large-scale production needs of the transformer manufacturing industry. Summary of the Invention

[0004] A coil mounting device for transformer processing includes a mounting assembly for stably mounting the coil onto an iron core. The mounting assembly includes a first component and a second component. The first component is used to calibrate the coil, and the second component is used to calibrate the iron core and mount the iron core and the coil. The first component includes two support plates and two sliding plates, all of which are L-shaped and have inclined bottom ends. The inner surfaces of the support plates and sliding plates are made of rubber. The second component includes a bearing shaft and four push plates, which are also made of rubber.

[0005] Furthermore, the first component also includes a base box, on the top of which two support frames are symmetrically and fixedly connected. A hydraulic rod is fixedly connected to the top of each support frame, with the telescopic shaft ends of the two hydraulic rods facing each other. Two pallets are respectively fixedly connected to the telescopic shaft ends of the two hydraulic rods. A threaded rod is rotatably connected to each of the two pallets, and a support plate is threaded onto each of the two threaded rods. Two guide rods are symmetrically and slidably connected to each of the two support plates, and the guide rods are fixedly connected to the adjacent pallets. Two sliding plates are slidably connected to the two support plates. Multiple positioning grooves are evenly distributed on each of the two support plates. An insert rod is slidably connected to each of the two sliding plates, and a spring is fitted onto the insert rod. The two ends of the spring are fixedly connected to the sliding plate and the insert rod, respectively. A servo motor is fixedly connected to each of the two pallets, and the output shafts of the two servo motors are fixedly connected to the adjacent threaded rods. Multiple ball bearings are evenly and rotatably connected to each of the two pallets and the two sliding plates.

[0006] Furthermore, the second component also includes four support frames, which are fixedly connected to the top surface of the base box in a rectangular array. The base box is equipped with two guide rods and two reciprocating screws. Each guide rod and reciprocating screw is grouped together, with two groups in total. The two groups of guide rods and reciprocating screws are staggered vertically. Guide rods and reciprocating screws in the same group are located on the same plane. The two guide rods and two reciprocating screws form a rectangle on the base box. The two reciprocating screws are rotatably connected to adjacent support frames, and the two guide rods are fixedly connected to adjacent support frames. Each reciprocating lead screw is fixedly connected to a servo motor II. Both servo motor IIs are fixedly connected to the same support frame. Four push plates are symmetrically threaded onto the two reciprocating lead screws in pairs. The end of the push plate away from the reciprocating lead screw is slidably connected to a guide rod II on the same horizontal plane. A scissor lift platform is installed in the base box. A support box is fixedly connected to the top of the scissor lift platform. Two guide plates are symmetrically slidably connected in the support box. The two guide plates are vertically distributed. The support shaft is slidably connected to the two guide plates at the same time. The top of the support shaft is rotatably connected to a carrier plate.

[0007] Furthermore, the insertion rod and the positioning slot are inserted and mated together.

[0008] Furthermore, the bottom end of the bearing shaft slides into the inner wall of the bearing box.

[0009] A method for assembling coils for transformer processing includes the following steps: Step 1: Place the iron core on the carrier plate, then start the servo motor 2. The servo motor 2 drives the reciprocating lead screw to rotate, causing the push plate on it to move towards the center along the guide rod 2. Four rubber push plates adhere to and push the iron core from all sides. By utilizing the sliding and rotation of the bearing shaft on the guide plate, the iron core is finally corrected and limited to the center position of the base box.

[0010] Step 2: Adjust the position of the slide plate according to the size of the coil. Pull the plug out to stretch the spring, disengage the plug from the positioning slot, and then slide the slide plate to the desired position. Release the plug; under the spring's rebound force, the plug will insert into the new positioning slot to fix the slide plate. After adjustment, align the bottom surface of the coil with the ball bearings on the support plate and the slide plate.

[0011] Further, in step three: activate the two hydraulic rods and two servo motors. The telescopic shafts of the hydraulic rods extend, pushing the two support plates to move towards each other. The servo motors drive the threaded rods to rotate, causing the support plate and slide plate to move towards each other along the guide rod. The L-shaped support plate and slide plate close from four directions. The sloping design at the bottom helps to scoop into the bottom of the coil. Finally, the coil is flexibly contacted and pushed through the inner surface of the rubber, so that it is accurately centered to the center of the base box and is limited.

[0012] Step 4: Drive the servo motor 2 to reverse, so that the four push plates move away from each other, release the limit on the iron core, and then start the scissor lift platform to push the carrier box and the iron core above it to rise smoothly. Since the iron core and the coil are precisely aligned, the iron core can be smoothly and coaxially inserted into the internal cavity of the coil until the carrier plate contacts the lower surface of the support plate and the slide plate.

[0013] Further, in step five: reverse the servo motor and simultaneously control the extension shaft of the hydraulic rod to retract. This will cause the pallet and slide plate to move away from the center of the coil. Under the action of gravity, the coil slides down the slope of the pallet and slide plate and is finally completely and smoothly fitted onto the iron core. After that, the scissor lift platform descends, thus completing the entire fitting process.

[0014] Compared with the prior art, the beneficial effects of the present invention are: through the operation of the assembly components, the assembly of the iron core and the coil can be completed safely and efficiently, protecting the insulation structure, replacing the inefficient mode of traditional manual assembly. Through mechanical positioning and flexible clamping, the coil is stably and coaxially assembled onto the iron core, avoiding scratches and damage to the coil insulation layer. At the same time, the assembly position deviation is precisely controlled, improving the assembly accuracy of the iron core and the coil, greatly reducing the intensity of manual labor, and adapting to the coil assembly requirements of transformers of different capacities.

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Example 1: Referring to Figures 1 to 9, a coil mounting device for transformer processing includes a mounting assembly. The mounting assembly is used to smoothly mount the coil 12 onto the iron core 11. The mounting assembly includes a first component and a second component.

[0019] The first component is used to correct coil 12.

[0020] The first component includes a base box 21. Two support frames 22 are symmetrically fixedly connected to the top of the base box 21. A hydraulic rod 213 is fixedly connected to the top of each support frame 22. The telescopic shaft ends of the two hydraulic rods 213 face each other. A support plate 23 is fixed to the telescopic shaft end of each hydraulic rod 213. A threaded rod 24 is rotatably connected to each of the two support plates 23. A support plate 26 is threadedly connected to each of the two threaded rods 24. Two guide rods 25 are symmetrically slidably connected to each of the two support plates 26. The guide rods 25 are fixedly connected to the adjacent support plate 23. Each of the two support plates 26 has a sliding plate 27 slidably connected to it. Each of the two support plates 26 has multiple positioning grooves 28 evenly distributed. Each of the two sliding plates 27 has a sliding rod 29 slidably connected to it. A spring 210 is sleeved on the rod 29. The two ends of the spring 210 are fixedly connected to the sliding plate 27 and the rod 29, respectively. Each of the two support plates 23 has a servo motor 211 fixedly connected to it. The output shafts of the two servo motors 211 are fixedly connected to the adjacent threaded rods 24, respectively. Multiple balls 212 are evenly rotatably connected to each of the two support plates 23 and the two sliding plates 27.

[0021] Among them, the two support plates 23 and the two slide plates 27 are all L-shaped, and the bottom ends of the two support plates 23 and the two slide plates 27 are all sloped.

[0022] Among them, the inner surfaces of the support plate 23 and the slide plate 27 are made of rubber, which serves to provide flexible correction.

[0023] Among them, the insertion rod 29 is inserted into the positioning groove 28.

[0024] Among them, the ball bearing 212 is a limit-type rotating connection on both the pallet 23 and the slide plate 27.

[0025] The second component is used to calibrate the iron core 11 and to assemble the iron core 11 with the coil 12.

[0026] The second component includes four support frames 31, which are fixedly connected to the top surface of the base box 21 in a rectangular array. The base box 21 is equipped with two guide rods 32 and two reciprocating screws 33. Each guide rod 32 and reciprocating screw 33 is grouped together, with two groups in total. The two groups of guide rods 32 and reciprocating screws 33 are staggered vertically. Within the same group, the guide rods 32 and reciprocating screws 33 are located on the same plane. The two guide rods 32 and two reciprocating screws 33 form a rectangle on the base box 21. The two reciprocating screws 33 are rotatably connected to adjacent support frames 31, and the two guide rods 32 are fixedly connected to adjacent support frames 31. Each rod 33 is fixedly connected to a servo motor 34. Both servo motors 34 are fixedly connected to the same support frame 31. Each of the two reciprocating screws 33 is symmetrically threaded with two push plates 35. The end of the push plate 35 away from the reciprocating screw 33 is slidably connected to a guide rod 32 on the same horizontal plane. A scissor lift platform 36 is installed in the base box 21. A support box 37 is fixedly connected to the top of the scissor lift platform 36. Two guide plates 38 are symmetrically slidably connected in a staggered manner in the support box 37. The two guide plates 38 are distributed vertically. A support shaft 39 is slidably connected to both guide plates 38. A carrier plate 310 is rotatably connected to the top of the support shaft 39.

[0027] Among them, the push plate 35 is made of rubber.

[0028] Among them, the scissor lift platform 36 is a known existing technology. The scissor lift platform 36 uses hydraulic drive to extend and retract the scissor arms, thereby driving the upper load-bearing box 37 to rise and fall smoothly. The cross-hinged structure of the scissor arms can realize flexible adjustment of the lifting stroke, while ensuring stability and load-bearing capacity during the lifting process.

[0029] Wherein: the bottom end of the bearing shaft 39 is in sliding fit with the inner wall of the bearing box 37.

[0030] In the initial state of the assembly, before the core 11 and coil 12 are assembled, the structures within the assembly are as follows: the telescopic shafts of the two hydraulic rods 213 are fully retracted, and the two support plates 26 are located on the side away from the first support plate 23 on the corresponding threaded rod 24. The two sliding plates 27 are located on the side away from the threaded rod 24 on the corresponding support plates 26, and the insertion rod 29 is inserted into the positioning slot 28 at its current position without elastic deformation. At this time, the distance between the two first support plates 23 and the two sliding plates 27 is at its maximum. The push plate 35 is located at the end position on the corresponding reciprocating screw 33 and guide rod 32, meaning the spacing between the four push plates 35 is at its maximum. The scissor lift platform 36 is not extended, the load box 37 is located inside the base box 21, and the load shaft 39 is located in the center of the load box 37.

[0031] When the assembly process is underway, specifically during the assembly of the iron core 11 and coil 12, the following steps are taken: The user places the iron core 11 on the top surface of the carrier plate 310. After completion, the user activates two servo motors 34. As the two servo motors 34 are activated, their output shafts drive the corresponding reciprocating screws 33 to rotate. With the rotation of the reciprocating screws 33, there is a tendency for the push plates 35 to deflect along the thread direction. However, due to the sliding limit effect of the guide rod 32, the push plates 35 can only move along the axial direction of the guide rod 32. Furthermore, as the two servo motors 34 are activated, the two push plates 35 on the same reciprocating screw 33 move closer to each other, meaning the spacing between the four push plates 35 forming the frame gradually decreases.

[0032] Because the iron core 11 was manually placed on the carrier plate 310, its position on the base box 21 was misaligned. During the movement of the push plate 35, the push plate 35 contacts and pushes the iron core 11, moving it to the center of the base box 21, thus correcting the iron core 11 so that it is in contact with all four push plates 35. During this correction process, the iron core 11, under its own weight, moves the carrier plate 310 synchronously. As the carrier plate 310 moves, it can rotate on the two guide plates 38 via the bearing shaft 39, thus pushing the misaligned iron core 11 into contact with all four push plates 35. The carrier plate 310 can also slide on the two guide plates 38 via the bearing shaft 39, and the sliding engagement of the two guide plates 38 within the carrier box 37 allows the carrier plate 310 to move freely within the carrier box 37. Then, as the four push plates 35 push the iron core 11 to the center of the base box 21 and the iron core 11 is in contact with the four push plates 35, the iron core 11 is then corrected in position on the base box 21 and limited by the four push plates 35.

[0033] After completion, the user adjusts the size of the coil 12 according to the requirements, adjusts the position of the slide plate 27 on the support plate 26, and pulls out the plug rod 29, so that the spring 210 is elastically stretched. At this time, the plug rod 29 is disengaged from the positioning groove 28. The user moves the slide plate 27 to the desired position, so that the slide plate 27 slides on the support plate 26. When the slide plate 27 moves to the desired position, the user no longer pulls the plug rod 29. Under the action of the elastic reset of the spring 210, the plug rod 29 is inserted into the positioning groove 28 at the corresponding position.

[0034] The user then places the coil 12 on either of the trays 23 or the slide 27, ensuring the bottom surface of the coil 12 is in contact with the ball bearing 212. The user then activates the two hydraulic rods 213 and the two servo motors 211. The telescopic shafts of the two hydraulic rods 213 extend, pushing the two trays 23 closer together. Simultaneously, the output shafts of the two servo motors 211 rotate the threaded rod 24. While the threaded rod 24 rotates, it tends to deflect the support plate 26 along the threaded direction. However, the support plate 26 is limited by the sliding stop of the guide rod 25, allowing it to slide only along the axial direction of the guide rod 25. Thus, as the output shafts of the servo motors 211 rotate, the two slides 27 move closer together. When the rectangular dimensions formed by the two trays 23 and the two slides 27 reach the dimensions of the coil 12 that needs to be assembled, the user stops the operation of the servo motor 211 and the hydraulic rod 213, so that the positions of the trays 23 and the slides 27 are fixed.

[0035] It should be noted that the rectangle formed by the two support plates 23 and the two slide plates 27 is expanded or reduced at equal intervals with the center point of the base box 21 as the center.

[0036] During this process, coil 12 is pushed towards the center of base box 21. The other support plates 23 or slide plates 27, which were not previously in contact with coil 12, are inserted into the bottom of coil 12 through their inclined surfaces, so that the ball bearings 212 on each support plate 23 and slide plate 27 come into contact with the bottom surface of coil 12. The function of the ball bearings 212 is to reduce the resistance to movement. As the vertical surfaces of the two support plates 23 and the two slide plates 27 are in contact with the outer wall of coil 12, coil 12 is now aligned to the center of base box 21, and coil 12 is limited by the two support plates 23 and the two slide plates 27. The bottom of the two support plates 23 and the two slide plates 27 do not extend into the bottom cavity of coil 12.

[0037] At this point, both coil 12 and iron core 11 are calibrated and limited. After completion, the user drives the two servo motors 34 to run, causing the output shafts of the servo motors 34 to rotate in the opposite direction, causing the four push plates 35 to move away from each other, thereby releasing the limited state of iron core 11 and making the push plates 35 no longer located on the moving path of iron core 11. Then, the user drives the support plate 26 to run, causing the support plate 26 to push the iron core 11 to move upward. Since the iron core 11 and coil 12 are both calibrated to the center position of the base box 21, the iron core 11 can be directly inserted from the bottom of coil 12 until the carrier plate 310 touches the lower surface of the support plate 23 and the slide plate 27. At this time, the user drives the servo motor 211 and the hydraulic rod 213 to run, causing the output shafts of the two servo motors 211 to reverse and the telescopic shafts of the two hydraulic rods 213 to retract. Then, the two support plates 23 and the two sliding plates 27 move outward at the bottom of the coil 12. At this time, under the action of gravity, the coil 12 moves downward along the slope of the support plates 23 and the sliding plates 27 until the coil 12 is completely fitted onto the iron core 11. After completion, the user drives the support plate 26 to retract and put the sliding plates 27 back into the base box 21. At this time, the fitting of the iron core 11 and the coil 12 is completed, and the user can take away the fitted iron core 11 and the coil 12.

[0038] It should be noted that in the above process, since the guide rod 25 is made of rubber, it can provide flexible correction for the iron core 11. The inner surfaces of the support plate 23 and the slide plate 27 are also made of rubber, which can provide flexible correction for the coil 12. Furthermore, the iron core 11 and the coil 12 are fitted together after being aligned in position, which can ensure that the coil 12 is fitted onto the iron core 11 stably and coaxially.

[0039] In summary, the following beneficial effects can be achieved through the operation of the assembly kit: the assembly of the iron core 11 and coil 12 can be completed safely and efficiently, protecting the insulation structure and replacing the inefficient traditional manual assembly method. Through mechanical positioning and flexible clamping, the coil 12 is stably and coaxially assembled onto the iron core 11, avoiding scratches and damage to the insulation layer of the coil 12. At the same time, the assembly position deviation is precisely controlled, improving the assembly accuracy of the iron core 11 and coil 12, significantly reducing the intensity of manual labor, and adapting to the coil 12 assembly requirements of transformers with different capacities.

[0040] Example 2: A method for assembling coils for transformer processing, comprising the following steps: Step 1: Place the iron core 11 on the carrier plate 310, then start the servo motor 2 34, the servo motor 2 34 drives the reciprocating lead screw 33 to rotate, driving the push plate 35 on it to move towards the center along the guide rod 2 32, the four rubber push plates 35 adhere to and push the iron core 11 from all sides, and by using the sliding and rotation of the bearing shaft 39 on the guide plate 38, the iron core 11 is finally corrected and limited to the center position of the base box 21.

[0041] Step 2: Adjust the position of the slide plate 27 according to the size of the coil 12. Pull out the plug rod 29 to stretch the spring 210, releasing the plug rod 29 from the positioning groove 28. The slide plate 27 can then be slid to the desired position. Release the plug rod 29. Under the rebound force of the spring 210, the plug rod 29 will insert into the new positioning groove 28 to fix the slide plate 27. After adjustment, make the bottom surface of the coil 12 contact the ball bearings 212 on the support plate 23 and the slide plate 27.

[0042] Step 3: Activate the two hydraulic rods 213 and the two servo motors 211. The telescopic shafts of the hydraulic rods 213 extend, pushing the two support plates 23 to move towards each other. The servo motors 211 drive the threaded rod 24 to rotate, causing the support plate 26 and the slide plate 27 to move towards each other along the guide rod 25. The L-shaped support plates 23 and the slide plate 27 close from four directions. The sloping design at the bottom helps to scoop into the bottom of the coil 12. Finally, through the flexible contact of the inner surface of the rubber, the coil 12 is pushed to accurately center itself to the center of the base box 21 and is limited.

[0043] Step 4: Drive the servo motor 2 34 to reverse, so that the four push plates 35 move away from each other, release the limit on the iron core 11, and then start the scissor lift platform 36 to push the carrier box 37 and the iron core 11 above it to rise smoothly. Since the iron core 11 and the coil 12 are precisely aligned, the iron core 11 can be smoothly and coaxially inserted into the internal cavity of the coil 12 until the carrier plate 310 contacts the lower surface of the support plate 23 and the slide plate 27.

[0044] Step 5: Reverse the servo motor 211 and simultaneously retract the telescopic shaft of the hydraulic rod 213. This will cause the pallet 23 and the slide plate 27 to move away from the center of the coil 12. Under the action of gravity, the coil 12 slides down the slope of the pallet 23 and the slide plate 27 and finally fits completely and smoothly onto the iron core 11. After that, the scissor lift platform 36 descends, thus completing the entire fitting process.

The scissor lift platform (36) is installed in the base box (21). The top of the scissor lift platform (36) is fixedly connected to the support box (37). The support box (37) has two guide plates (38) slidably connected in a staggered manner. The two guide plates (38) are vertically distributed. The support shaft (39) is slidably connected to the two guide plates (38). The top of the support shaft (39) is rotatably connected to the carrier plate (310).

4. A coil assembly device for transformer processing according to claim 2, characterized in that: The insertion rod (29) is inserted into the positioning groove (28).

5. A coil assembly device for transformer processing according to claim 3, characterized in that: The bottom end of the bearing shaft (39) slides into the inner wall of the bearing box (37).

6. A method for assembling coils for transformer processing, characterized in that: The application of the coil assembly device for transformer processing as described in claim 5 includes the following steps: Step 1: Place the iron core (11) on the carrier plate (310), and then start the servo motor 2 (34). The servo motor 2 (34) drives the reciprocating screw (33) to rotate, which drives the push plate (35) on it to move towards the center along the guide rod 2 (32). The four rubber push plates (35) adhere to and push the iron core (11) from all sides. By using the sliding and rotation of the bearing shaft (39) on the guide plate (38), the iron core (11) is finally corrected and limited in the base box. (21) The center position; Step 2: Adjust the position of the slide plate (27) according to the size of the coil (12), pull out the plug rod (29) to stretch the spring (210), release the plug rod (29) from the positioning groove (28), and slide the slide plate (27) to the desired position. Release the plug rod (29), and under the action of the spring (210) rebound force, the plug rod (29) will be inserted into the new positioning groove (28) to fix the slide plate (27). After the adjustment is completed, make the bottom surface of the coil (12) contact the ball (212) on the support plate (23) and the slide plate (27).

7. A method for assembling coils for transformer processing according to claim 6, characterized in that: Step 3: Activate the two hydraulic rods (213) and the two servo motors (211). The telescopic shafts of the hydraulic rods (213) extend, pushing the two pallets (23) to move towards each other. The servo motors (211) drive the threaded rod (24) to rotate, causing the support plate (26) and the slide plate (27) to move towards each other along the guide rod (25). The L-shaped pallets (23) and slide plate (27) close from four directions. The sloping design at the bottom helps to scoop into the bottom of the coil (12), and finally, through the flexible contact of the inner surface of the rubber, push the coil (12) to make it... It is accurately aligned to the center of the base box (21) and is limited; Step 4: Drive the servo motor 2 (34) to reverse, so that the four push plates (35) move away from each other, release the limit on the iron core (11), and then start the scissor lift platform (36) to push the carrier box (37) and the iron core (11) above it to rise smoothly. Since the iron core (11) and the coil (12) are accurately aligned, the iron core (11) can be smoothly and coaxially inserted into the internal cavity of the coil (12) until the carrier plate (310) contacts the lower surface of the support plate 1 (23) and the slide plate (27).

8. A method for assembling coils for transformer processing according to claim 6, characterized in that: Step 5: Reverse the servo motor (211) and simultaneously control the extension shaft of the hydraulic rod (213) to retract. This will cause the pallet (23) and the slide plate (27) to move away from the center of the coil (12). Under the action of gravity, the coil (12) slides down the slope of the pallet (23) and the slide plate (27) and finally fits completely and smoothly onto the iron core (11). After that, the scissor lift platform (36) descends, thus completing the entire fitting process.
