[0002] In the production and processing of current transformers, in order to realize the electromagnetic induction function of the current transformer, multiple turns of copper wire need to be wound on the iron core of the current transformer, so that the current transformer can perform electromagnetic induction operation normally.

[0003] A search revealed Chinese Patent Publication No. CN119650294A, which discloses a winding device for current transformer production. The device includes a base and a mounting bracket disposed on one side of the upper surface of the base. A wire storage ring is perforated on one side of the mounting bracket. A feeding platform is movably mounted with a slot on the upper surface of the base. A clamping mechanism for positioning a rectangular iron core is disposed on the upper surface of the feeding platform. A rotating mechanism for driving the iron core to rotate and wind the wire is disposed on one side inside the base. A driving mechanism for driving the wire storage ring and the feeding platform is disposed within the mounting bracket and the base. A controller is also disposed on the upper surface of the base. This invention has a simple structure and reasonable design, achieving the effect of vertically and uniformly winding the enameled wire onto the rounded corners of the rectangular iron core, avoiding winding tilt. This reduces the amount of enameled wire used, saves production costs, and improves the electrical performance of the current transformer as well as its stability and reliability in later applications.

[0004] The aforementioned device drives the iron core to rotate around the center of the rounded corner via a rotating mechanism. In conjunction with the linkage of the drive mechanism and the clamping mechanism, the enameled wire is wound perpendicular to the outer wall of the iron core, achieving seamless switching between side and rounded corner winding. However, in actual use, the aforementioned device is only designed for rectangular iron cores with fixed rounded corner radii and cannot be adapted to iron cores with different rounded corner radii, resulting in a limited range of applicable scenarios and poor versatility.

[0007] The above technical solution involves moving a double-headed cylinder to push multiple sliding rods to move and fit against the inner corner of the rectangular iron core, thereby achieving matching for different corner radii of the rectangular iron core.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 4 as well as Figure 7 and attached Figure 8 This invention provides a processing equipment for producing current transformer windings, including a winding device 1. A rectangular iron core 3 is disposed above the winding device 1. An air pump 20 and a controller 2 are disposed outside the winding device 1. Multiple air pipes 26 are fixedly disposed at the output end of the air pump 20. A support base 5 is slidably connected to the upper side of the winding device 1. Double-headed cylinders 4 are slidably connected to the four corners of the inner bottom wall of the support base 5. A support rod 7 is fixedly disposed at the upper end of the output end of the double-headed cylinder 4. A support rod 7 is fixedly connected to the outer wall of the support rod 7 for support. The outer wall of the support plate 10 and support rod 7 of the rectangular iron core 3 is fixed with multiple sliding cylinders 14. The multiple sliding cylinders 14 are stacked in sequence at a preset angle. One end of each of the multiple sliding cylinders 14 is fixed to the outer wall of the air pipe 26. The other end of each sliding cylinder 14 is slidably connected to a sliding rod 13. One end of each sliding rod 13 is attached to the inner rounded corner of the rectangular iron core 3. The inner bottom wall of the winding device 1 is fixed with a motor 27. The output end of the motor 27 is fixedly located at the lower end of the output end of one of the double-headed cylinders 4.

[0037] In this embodiment, Figure 1The directions are front, back, left, and right. The winding device 1 includes a base 100, a mounting bracket 101 fixed on the upper side of the base 100, a storage ring 102 rotatably connected to the front side of the mounting bracket 101, a feeding platform 103 sliding between the side walls of the base 100, a support seat 5 sliding on the upper side of the feeding platform 103, a rectangular groove for the lower ends of the output ends of the two rear double-headed cylinders 4 to pass through on the upper side of the feeding platform 103, a drive mechanism 104 installed inside the base 100, the drive mechanism 104 is used to drive the left and right movement of the feeding platform 103 and the winding operation of the storage ring 102, an auxiliary support bracket 105 is also fixed on the upper side of the base 100 to assist in fixing the storage ring 102; the controller 2 can be a PLC programmable controller, the air pump 20 can be a micro pneumatic pump, and it is used in conjunction with an electromagnetic reversing valve and a rotary joint for the rotation between the double-headed cylinders 4 and the support seat 5. In addition, this device can also use hydraulic power to drive the movement of the slide bar 13. All of the above are existing technologies.

[0038] Specifically, there are three sliding cylinders 14. The angle between the two outer sliding cylinders 14 is a right angle, and the middle sliding cylinder 14 bisects the angle between the two outer ones. When using this device, by moving the double-headed cylinders 4, the distance between the four double-headed cylinders 4 matches the size of the rectangular iron core 3. The inner side of the left rear corner of the rectangular iron core 3 is brought close to the outer wall of the left rear support rod 7. The controller 2 controls the air pump 20 to start, inflating the air pipe 26. This causes the gas to push the three sliding rods 13 to move synchronously towards the rectangular iron core 3. The middle sliding rod 13... Push the left rear corner of the rectangular iron core 3 to move. When the ends of the three slide rods 13 are all in contact with the inner side of the left rear corner of the rectangular iron core 3, the double-headed cylinder 4 on the left rear side completes the positioning of the center of the rounded corner of the rectangular iron core 3. Similarly, by sliding the other three slide rods 13, the positioning of the center of the four corners of the rectangular iron core 3 is completed. By continuing to inflate the air pump 20, the rectangular iron core 3 is limited and fixed by the four sets of slide rods 13. At this time, the rectangular iron core 3 is supported by the support plate 10 on the lower side, thus realizing the function of the device to adapt to different rounded corner radii.

[0039] Controlled by controller 2, the output of the double-headed cylinder 4 drives the rectangular iron core 3 to move upward to the winding area. Driven by the drive mechanism 104, the feeding platform 103 moves to the left. Simultaneously, controller 2 controls the mounting frame 101 and the storage ring 102 to run, winding the rectangular iron core 3 on all four sides. When encountering a rounded corner, controller 2 controls the air pump 20 to release the air supply to the left rear air pipe 26 and extract the gas, causing the slide bar 13 to release the limiting fixation on the left rear side of the rectangular iron core 3. The output of the double-headed cylinder 4 is driven to move downward and insert into the output of the motor 27. Driven by the output of the motor 27, the support base 5 rotates around the center of the rounded corner. In conjunction with the winding of the storage ring 102, the function of winding the rounded corner is completed. This solves the problem in the prior art that it cannot adapt to iron cores with different rounded corner radii, resulting in a single applicable scenario and poor versatility.

[0040] Based on the above embodiments, the only way to check whether the slide bar 13 is in contact with the inner side of the rectangular iron core 3 is by manual observation, resulting in low feeding efficiency. To solve the above problem, please refer to the appendix. Figure 2 A pressure sensor 12 is installed at one end of the slide bar 13, and the pressure sensor 12 is electrically connected to the controller 2.

[0041] Specifically, the contact between the slide bar 13 and the inner side of the rectangular iron core 3 allows the pressure sensor 12 to transmit the generated pressure signal to the controller 2 for processing and analysis in real time. That is, when the pressure values ​​of multiple pressure sensors 12 are consistent, the center of the rounded corner of the rectangular iron core 3 is located. Subsequently, the continued pressurization of the air pump 20 will make the pressure values ​​of multiple pressure sensors 12 consistent or maintained within a reasonable range, thereby helping to improve the feeding efficiency of the equipment.

[0042] Specifically, based on the above embodiment, manually adjusting the position of the double-headed cylinder 4 requires a significant amount of time to adjust its position when the winding core needs to be replaced, thus reducing the applicability of the equipment. To solve the above problem, please refer to the appendix. Figure 1 and attached Figure 6 The inner bottom wall of the support base 5 is fixed with a cross slide 23 and a linear module 24. The output end of the cross slide 23 is fixedly set on the outer wall of a double-headed cylinder 4, and the output end of the linear module 24 is fixedly set on the outer wall of another double-headed cylinder 4. The other two double-headed cylinders 4 are respectively set at both ends of one side of the cross slide 23, and the angle between the line connecting two adjacent double-headed cylinders 4 is a right angle. The inner bottom wall of the support base 5 is provided with a groove 25 that slides with the lower end of the output end of the double-headed cylinder 4.

[0043] Specifically, the lower sides of the dual-head cylinder 4 are all fixed on the mounting base. The mounting base on the left rear side is on the outer wall of the left rear side of the cross slide 23. The mounting base on the left front side is fixed on the front left end of the front and rear moving seat of the cross slide 23, and the line connecting the left rear side mounting base is parallel to the left side of the support seat 5. The mounting base on the right rear side is fixed on the output end of the linear module 24. The mounting base on the right front side is fixed on the front side of the output end of the cross slide 23. The mounting base on the right side is parallel to the right side of the support seat 5. The front mounting base is parallel to the rear mounting base.

[0044] Driven by the cross slide 23, the two double-headed cylinders 4 on the front side can move synchronously back and forth. With the cooperation of the cross slide 23 and the linear module 24, the two double-headed cylinders 4 on the right side can move synchronously left and right, so that the double-headed cylinders 4 can be adapted to rectangular iron cores 3 of different sizes. With the cooperation of the pressure sensor 12, the controller 2 can process the data fed back by the pressure sensor 12 and adjust the position of the double-headed cylinders 4 in real time to locate the center of the circle more quickly, thereby realizing the function of automatically matching different rounded corner radii of the device.

[0045] Based on the above embodiment, when the rectangular iron core 3 is placed, it may tilt horizontally, increasing the complexity of adjusting the position of the rectangular iron core 3 and the double-headed cylinder 4, and reducing the feeding efficiency. To solve the above problem, please refer to the appendix. Figure 1 and attached Figure 6 Multiple positioning plates 22 are fixed on the upper side of the support base 5, and the outer wall of the positioning plate 22 is attached to the inner side of the rectangular iron core 3.

[0046] Specifically, when placing the rectangular iron core 3, the rear and left sides of the rectangular iron core 3 are attached to the outer wall of the positioning plate 22, and the inner side of the rounded corner of the rectangular iron core 3 is attached to the outer wall of the support rod 7, thereby completing the three-point positioning, which helps to improve the feeding efficiency of the equipment.

[0047] Based on the above embodiment, the air pump 20 pressurizes the rectangular iron core 3, causing multiple sliding rods 13 to limit and fix it. However, when winding the rectangular iron core 3, the force applied to the wire can cause the rectangular iron core 3 to tilt, which will affect the winding quality. To solve the above problem, please refer to the appendix. Figure 1 Appendix Figure 2 and attached Figure 3 A slide cylinder 25 is fixedly installed at the upper end of the trachea 26. Both ends of the slide cylinder 25 are slidably connected to slide rods 26. An electromagnet 21 is rotatably connected to the outer wall of the end of the slide rod 26. The outer wall of the electromagnet 21 and the inner side of the rectangular iron core 3 are magnetically attracted.

[0048] Specifically, when the air pump 20 inflates the air tube 26, it will push the second slide bar 16 to move closer to the inside of the rectangular iron core 3. After a certain period of time, the two second electromagnets 11 are powered on and generate a repulsive force, causing the second electromagnets 11 to rotate away from each other. When the second electromagnets 11 move to fit the rectangular iron core 3, the second electromagnets 11 and the rectangular iron core 3 are fixed by magnetic adsorption, further limiting the rectangular iron core 3, thus avoiding the situation where the rectangular iron core 3 tilts during winding.

[0049] Based on the above embodiment, the device can only use rectangular and U-shaped iron cores and cannot wind the commonly used circular iron cores, which reduces the applicability of the device. To solve the above problems, please refer to the attached Figure 2 and the attached Figure 4 Above the winding device 1, a circular iron core 19 is provided. A roller 8 is rotatably connected to the outer wall of the support rod 7. A first motor 9 is fixed to the outer wall of one of the support plates 10. The output end of the first motor 9 is fixedly arranged on the outer wall of one of the rollers 8. The vertical projection of the roller 8 is in the shape of a Chinese character "tu". The outer walls of multiple rollers 8 are all in rolling contact with the inside of the circular iron core 19.

[0050] Specifically, a first gear is fixedly arranged at the output end of the first motor 9, and a second gear is fixed to the outer wall of the left and rear roller 8. When winding the circular iron core 19, the self-diameter parameter of the circular iron core 19 is input through the pressure sensor 12, and the pressure sensor 12 adjusts the position of the double-headed cylinder 4, so that the outer walls of the rollers 8 on multiple double-headed cylinders 4 are all in contact with the inside of the circular iron core 19. Due to the "tu" shape of the roller 8, the roller 8 can also support the lower side of the circular iron core 19. Through the drive of the drive mechanism 104 and the cooperation of the double-headed cylinder 4, the circular iron core 19 is moved to the winding area. At this time, through the drive of the output end of the first motor 9, the first gear is driven to rotate. Through the cooperation of the second gear, the roller 8 is further driven to rotate, driving the circular iron core 19 to rotate for winding, thus realizing the function of the device adapting to winding iron cores of various shapes.

[0051] Based on the above embodiment, it is necessary to manually reset the second electromagnet 11. After resetting, the shaking of the device is likely to cause the second electromagnet 11 to rotate, interfering with the winding of the circular iron core 19. To solve the above problems, please refer to the attached Figure 3 and the attached Figure 5 A first guide rod 17 and a second guide rod 18 are fixedly connected to the outer wall of the second sliding cylinder 15. The first guide rod 17 and the second guide rod 18 are both in sliding contact with the outer wall of the second electromagnet 11.

[0052] Specifically, when winding the circular iron core 19, the participation of slide rod 13 is not required. Therefore, with the cooperation of air pump 20, slide rod 13 retracts into slide cylinder 14, and slide rod 26 retracts into slide cylinder 25. During the retraction of slide rod 26, the outer wall of slide rod 26 will first touch guide rod 17. Through the sliding contact of guide rod 17 with electromagnet 21, electromagnet 21 rotates upward. Then, electromagnet 21 touches guide rod 28. Through the sliding contact of guide rod 28 and electromagnet 21, electromagnet 21 rotates completely above slide rod 26. At the same time, the upper side of guide rod 28 supports and limits the lower side of slide rod 26, thereby realizing the automatic reset and limiting function of electromagnet 21.

[0053] Please see the appendix Figure 1 and attached Figure 4 An electromagnet 6 is provided diagonally on the outer wall of the support base 5, and an iron plate 21 is fixed on the upper side of the winding device 1, which is magnetically attracted to the electromagnet 6.

[0054] Specifically, when the rectangular iron core 3 is linearly wound, the support base 5 needs to move together with the feeding table 103. Therefore, by setting the iron plate 21, when the support base 5 is wound on either side, there is an iron plate 21 and an electromagnet 6 that magnetically attract each other, thus fixing the support base 5 and helping to improve the winding efficiency of the equipment.

[0055] Please see the appendix Figure 8 The output end of motor 27 is fixedly provided with a conical locking block 28, and the lower end of the output end of double-headed cylinder 4 is provided with a sliding groove 29 that cooperates with the sliding of the conical locking block 28.

[0056] Specifically, when winding the rounded corners of the rectangular iron core 3, the downward movement of the output end of the double-headed cylinder 4 causes the conical block 28 to slide into the slide groove 29. This not only enables the power transmission of the motor 27, but also corrects the offset position of the support seat 5, thereby helping to improve the quality of winding the rounded corners of the rectangular iron core 3.

[0057] Work process: When in use, select either rectangular iron core 3 or circular iron core 19 according to processing requirements. If it is rectangular iron core 3, place it on the support plate 10 and attach it to the positioning plate 22 to complete the initial positioning. The controller 2 controls the cross slide 23 and linear module 24 to adjust the position of the four double-headed cylinders 4.

[0058] If it is a rectangular iron core 3, the controller 2 controls the air pump 20 to start, and inflates the slide cylinder 1 14 and slide cylinder 2 15 through the air pipe 26. The slide rod 1 13 extends and fits against the rectangular iron core 3. The pressure sensor 12 provides real-time feedback of the pressure signal. After the controller 2 confirms that the pressure meets the standard, the electromagnet 2 11 is energized and adsorbed to reinforce the rectangular iron core 3 in the processing scenario. If it is a circular iron core 19, multiple rollers 8 form a limiting support for the circular iron core 19, and the slide rod 1 13 and slide rod 2 16 retract.

[0059] When the rectangular iron core 3 is wound, the output end of the double-headed cylinder 4 drives the rectangular iron core 3 to rise to the preset winding area. The electromagnet 6 is energized to attract the iron plate 21 on the winding device 1 and fix the position of the support base 5. The drive mechanism 104 drives the feeding table 103 to move, and cooperates with the storage ring 102 to complete the linear winding. When encountering a rounded corner, the corresponding sliding rod 13 retracts, the output end of the double-headed cylinder 4 moves down to make the conical block 28 embed into the sliding groove 29. The motor 27 drives the support base 5 to rotate around the center of the rounded corner to complete the rounded corner winding. The winding of the four sides and four corners is completed in sequence.

[0060] When the circular iron core 19 is wound, the motor 9 starts and drives the roller 8 to rotate through gear transmission, which in turn drives the circular iron core 19 to rotate synchronously. This, together with the storage ring 102, completes the circumferential winding, thereby improving the functionality of the equipment for use in multiple scenarios.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
