Description

Technical Field

[0001] This utility model relates to the technical field of current transformer generation equipment, and in particular to a winding device for low-power current transformers. Background Technology

[0002] In power systems, low-power current transformers play a crucial role in converting large currents into smaller ones to facilitate the use of measurement, protection, and control equipment. A winding device for low-power current transformers is one of the key pieces of equipment in their production. Its main function is to evenly wind the conductors onto the transformer frame according to specific rules and the number of turns, ensuring the stability and reliability of the transformer's performance.

[0003] Early low-power current transformer winding devices mainly consisted of a simple winding shaft, a manual wire laying mechanism, and manual loading and unloading stations. Manual loading and unloading was not only inefficient but also prone to inaccurate loading positions and damage to the wound transformers during unloading, making it difficult to meet the needs of large-scale production. With technological advancements, existing winding devices have adopted automated winding shaft drive systems and precise wire laying structures, enabling more accurate winding operations. However, existing winding devices still have certain shortcomings. During operation, although the winding and wire laying processes are automated, manual operation is still required for loading and unloading. Operators need to frequently place the transformer frame at the loading station and remove the wound transformers from the unloading station. Due to individual differences in the speed and accuracy of manual operation, and the fatigue caused by prolonged operation, this not only limits the improvement of production efficiency but also affects the overall quality of transformer winding due to the instability of manual operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a winding device for a low-power current transformer, comprising a processing table 1. Limiting plates 14 are fixedly connected to the left and right sides of the top of the processing table 1. A servo motor 3 is fixedly connected to the top of the inner interior of the processing table 1. A bevel gear 4 is fixedly connected to the output end of the servo motor 3. A bevel gear 5 is meshed with the outer wall of the bevel gear 4. The top of the bevel gear 5 passes through the processing table 1 and is fixedly connected to an L-shaped rotating column 6. When the servo motor 3 is started, it drives the bevel gear 4 to rotate. The meshing relationship between the bevel gear 4 and the bevel gear 5 causes the bevel gear 5 to rotate, thereby driving the L-shaped rotating column 6 to rotate until it reaches above the winding assembly. An electric telescopic rod 7 is fixedly connected to the top of the inner wall of the L-shaped rotating column 6. An electromagnetic block 8 is fixedly connected to one end of the telescopic rod 7. Activating the electromagnetic block 8 attracts the workpiece. Activating the electric telescopic rod 7 moves the electromagnetic block 8 to the bottom, causing it to move along with the iron sheet 9. Multiple iron sheets 9 are fixedly connected to the outer wall of the electromagnetic block 8. A U-shaped plate 10 is fixedly connected to the top of the left limiting plate 14. Rotating columns 12 are rotatably connected to the front and rear sides of the inner wall of the U-shaped plate 10. A DC motor 11 is fixedly connected to the left side of the U-shaped plate 10. The output end of the DC motor 11 passes through the U-shaped plate 10 and is fixedly connected to the rear rotating column 12. A conveyor belt 13 is provided on the outer side of the two rotating columns 12. The DC motor 11 drives the rotating columns 12 to rotate, which in turn drives the outer conveyor belt 13 to rotate, causing the workpiece above to move downwards. The workpiece to be wound is conveyed to the front side. A winding assembly is provided on the top of the right limiting plate 14, and a feeding mechanism 2 is provided on the top of the U-shaped plate 10. The feeding mechanism 2 is used to neatly arrange the workpieces. The winding assembly includes two positioning cones 16, which are fixedly connected to the top left and right sides of the right limiting plate 14 respectively. An electrically driven cylinder 17 is fixedly connected to the front end of the top of the right limiting plate 14. Multiple auxiliary wheels 18 are fixedly connected to the top of the limiting plate 14. C-shaped wheels 15 are provided on the inner walls of the multiple auxiliary wheels 18. The outer walls of the C-shaped wheels 15 engage with the outer walls of the auxiliary wheels 18. A drive motor 19 is fixedly connected to the rear side of the top of the right limiting plate 14. A gear column 20 is fixedly connected to the output end of the drive motor 19. 0. The outer walls of the auxiliary wheel 18 and the C-shaped wheel 15 are both equipped with toothed belts 21. The bottom of the inner wall of the C-shaped wheel 15 is rotatably connected to the wire feeding column 22. The drive motor 19 rotates, which in turn causes the gear column 20 to rotate, and then drives the outer toothed belt 21 to rotate. Thus, under the restriction of the auxiliary wheel 18, the C-shaped wheel 15 rotates, and drives the wire feeding column 22 to rotate together. The electric telescopic rod 7 drives the electromagnetic block 8 to fall and demagnetizes the electromagnetic block 8, so that the workpiece falls above the positioning cone 16 and the electric drive cylinder 17. Then, the copper wire above the wire feeding column 22 passes through the hole above the workpiece. The top of the right limit plate 14 is rotatably connected to the arc strip 23, and the right side of the arc strip 23 is rotatably connected to the limit wheel 24.

[0032] Specifically, the DC motor 11 is started to drive the rotating column 12 to rotate, which in turn drives the outer conveyor belt 13 to rotate, so that the workpiece to be wound is transported to the front. At this time, the electric telescopic rod 7 is started to drive the electromagnetic block 8 to move to the bottom, so that the electromagnetic block 8 and the iron plate 9 move to the bottom together. Then, the electromagnetic block 8 is started to attract the workpiece. Then, the electric telescopic rod 7 drives the electromagnetic block 8 to retract, bringing the attracted workpiece up with it. Then, the servo motor 3 is started to drive the bevel gear 4 to rotate. The meshing relationship between the bevel gear 4 and the bevel gear 5 causes the bevel gear 5 to rotate, which in turn drives the L-shaped rotating column 6 to rotate until it reaches above the winding assembly. Then, the electric telescopic rod 7 drives the electromagnetic block... The electromagnetic block 8 is lowered, and its magnetism is released, causing the workpiece to fall above the positioning cone 16 and the electrically driven cylinder 17. Then, the copper wire above the wire feeding column 22 is passed through the hole above the workpiece. At this time, the drive motor 19 is started to rotate, which in turn causes the gear column 20 to rotate, and then drives the outer toothed belt 21 to rotate. Under the restriction of the auxiliary wheel 18, the C-shaped wheel 15 rotates, and drives the wire feeding column 22 to rotate together. With the slow rotation of the electrically driven cylinder 17, the copper wire is evenly wound around the top of the workpiece. After the winding is completed, the electromagnetic block 8 can be moved to the bottom by the electric telescopic rod 7, and the electromagnetic block 8 can be activated to remove the wound workpiece, thus completing the automatic loading and unloading steps.

[0033] Reference Figure 3 , Figure 4 and Figure 5 The feeding mechanism 2 includes a storage box 201. The bottom of the storage box 201 is fixedly connected to the rear top of the U-shaped plate 10. Circular columns 202 are rotatably connected to the front and rear sides of the inner wall of the storage box 201. Belt strips 203 are provided on the outer walls of the two circular columns 202. Driven by the connecting belt 206, the rear circular column 202 rotates together, which in turn drives the outer belt strip 203 to rotate. Multiple driving columns 204 are fixedly connected to the outer side of the belt strip 203. The right ends of the rear circular column 202 and the rear rotating column 12 both penetrate the storage box 201. The U-shaped plate 10 is fixedly connected to a pulley 205. When the DC motor 11 rotates, it will drive the rear rotating column 12, which in turn will drive the outer pulley 205 to rotate together. The outer walls of the two pulleys 205 are provided with a connecting belt 206. The front of the inner wall of the storage box 201 is fixedly connected to an inclined baffle 207. Under the guidance of the inclined baffle 207, it moves to the rear of the storage box 201 and then falls on the drive column 204. The bottom left and right sides of the inner wall of the storage box 201 are fixedly connected to guide bars 208. Under the guidance of the guide bars 208, it is adjusted towards the center.

[0034] Specifically, when the DC motor 11 rotates, it drives the rear rotating column 12, which in turn drives the outer pulley 205 to rotate as well. Under the drive of the connecting belt 206, the rear circular column 202 rotates as well, which in turn drives the outer belt 203 to rotate. At the same time, a large number of workpieces to be processed are placed in the storage box 201. Guided by the inclined baffle 207, they move to the rear of the storage box 201 and then land on the driving column 204. Under the rotation of the belt 203, the workpieces are moved forward and adjusted to the center under the guidance of the guide bar 208. Finally, they land on the front of the storage box 201 above the conveyor belt 13, thus completing the uniform feeding of the workpieces.

[0035] Reference Figure 1 , Figure 3 and Figure 4 An electric telescopic rod 25 is fixedly connected to the top left of the right limiting plate 14. The electric telescopic rod 25 can drive the hollow block 26 to move. One end of the electric telescopic rod 25 is fixedly connected to the hollow block 26. The hollow block 26 can restrict the movement of the sliding column 27. The left side of the arc strip 23 is fixedly connected to the sliding column 27. The outer wall of the sliding column 27 is slidably connected to the inner wall of the hollow block 26. When the electric telescopic rod 25 drives the hollow block 26 to move to the top, the sliding column 27 can drive the arc strip 23 to rotate. An I-shaped plate 28 is fixedly connected to the top front of the left limiting plate 14. The I-shaped plate 28 can provide a stable installation base for the subsequently connected stop block 29. The stop block 29 is fixedly connected to the rear side of the I-shaped plate 28. The stop block 29 can prevent the wound workpiece from continuing to move.

[0036] Specifically, the hollow block 26 can be moved by the electric telescopic rod 25, and the hollow block 26 can restrict the movement of the sliding column 27. When the electric telescopic rod 25 moves the hollow block 26 to the top, the sliding column 27 can drive the arc strip 23 to rotate. The I-shaped plate 28 can provide a stable installation base for the subsequently connected stop 29. The stop 29 can prevent the wound workpiece from continuing to move, thereby limiting the movement range of the components and ensuring the safety and accuracy of the equipment operation.

A warning sign block 37 is fixedly connected to the top front side of the left cabinet door 32. The warning sign block 37 reminds operators of safety issues to be aware of when operating the equipment or opening the cabinet door 32.

[0038] Specifically, the column 30 provides a mounting base for the warning light 31, ensuring it functions at a suitable height. The warning light 31 flashes or illuminates to warn operators of equipment malfunctions, abnormal operating conditions, or when certain precautions need to be taken. The cabinet door 32 allows operators easy access to the interior of the processing table 1. The L-shaped handle 33 facilitates gripping and applying force, easily opening and closing the cabinet door 32, improving operational convenience. The recess 34 provides installation space for the ventilation panel 35, and also allows for installation within the cabinet door 35. 2. When closed, ensure adequate air circulation to prevent dampness and stuffiness inside the processing table 1 due to poor air circulation. These are unfavorable environments for equipment operation. The ventilation plate 35 allows air to pass through while blocking larger dust particles and debris from entering the processing table 1, serving the dual purpose of ventilation and protection, and maintaining a good air environment inside the processing table 1. The nameplate 36 allows operators to easily understand the basic information of the equipment and also helps with equipment maintenance and management. The warning sign block 37 reminds operators of safety issues to be aware of when operating the equipment or opening the cabinet door 32, preventing accidents.

[0039] Working principle: First, the DC motor 11 is started to drive the rotating column 12 to rotate, which in turn drives the outer conveyor belt 13 to rotate, so that the workpiece to be wound is transported to the front. At this time, the electric telescopic rod 7 is started, causing the electromagnetic block 8 to move to the bottom. The electromagnetic block 8 and the iron plate 9 descend synchronously. Then, the electromagnetic block 8 is activated to attract the workpiece. Next, the electric telescopic rod 7 drives the electromagnetic block 8 to retract, lifting the attracted workpiece together. Then, the servo motor 3 is started, driving the bevel gear 4 to rotate. Through the meshing relationship between the bevel gear 4 and the bevel gear 5, the bevel gear 5 rotates, which in turn drives the L-shaped rotating column 6 to rotate until it reaches the top of the winding assembly. Then, the electric telescopic rod 7 drives the electric... The magnetic block 8 descends and demagnetizes the electromagnetic block 8, causing the workpiece to fall above the positioning cone 16 and the electrically driven cylinder 17. Then, the copper wire above the wire feeding column 22 is passed through the hole above the workpiece. At this time, the drive motor 19 is started to rotate, which in turn causes the gear column 20 to rotate, and then drives the outer toothed belt 21 to rotate. Under the restriction of the auxiliary wheel 18, the C-shaped wheel 15 rotates, and drives the wire feeding column 22 to rotate together. Under the slow rotation of the electrically driven cylinder 17, the copper wire is evenly wound around the workpiece. After the winding is completed, the electromagnetic block 8 is moved to the bottom by the electric telescopic rod 7, and the electromagnetic block 8 is activated to remove the wound workpiece, thus completing the automatic loading and unloading steps.

[0040] Furthermore, through the feeding mechanism 2, when the DC motor 11 is running, it will drive the rear rotating column 12, which in turn will cause the outer pulley 205 to rotate synchronously. Under the action of the connecting belt 206, the rear circular column 202 will also rotate, and at the same time drive the outer belt strip 203 to rotate. After a large number of workpieces to be processed are placed in the storage box 201, the workpieces will move to the rear of the storage box 201 by the guidance of the inclined baffle 207, and finally fall on the driving column 204. As the belt strip 203 continues to rotate, the workpieces are pushed forward and, with the assistance of the guide strip 208, are positioned and adjusted towards the center. Finally, the workpieces fall on the front side of the storage box 201 and above the conveyor belt 13, thereby achieving uniform supply of workpieces.
