Description

Technical Field

[0001] This application relates to the technical field of transformers, and in particular to a transformer winding device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). In power systems, transformers are key equipment for realizing the conversion and transmission of electrical energy, and the performance of their winding devices has a crucial impact on the stability and efficiency of power transmission.

[0003] Regarding the aforementioned technologies, the inventors believe that the winding operation in traditional technologies often makes it difficult to accurately control the position and tension of the windings, resulting in the winding uniformity and tightness not easily reaching the ideal state, which in turn affects the performance and service life of the transformer. Therefore, in order to solve the above problems, this application provides a transformer winding device. Utility Model Content

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A transformer winding device, as shown in the reference Figure 1 - Figure 4 The assembly includes a fixed platform 1, a rotating assembly, and a winding assembly. A portal frame 2 is fixedly connected to the surface of the fixed platform 1. A servo motor 3 is fixedly connected to the top of the portal frame 2. The output end of the servo motor 3 passes through the portal frame 2 and is fixedly connected to a lead screw 4 via a coupling. A guide block 5 is threadedly connected to the outside of the lead screw 4. A guide hole 6 for copper wires to pass through is opened inside the guide block 5. A limit rod 16 is slidably connected inside the guide block 5. The top end of the limit rod 16 is fixedly connected to the top inner wall of the portal frame 2, and the bottom end of the limit rod 16 is fixedly connected to the fixed platform 1. The bottom end of the lead screw 4 is rotatably connected to the surface of the fixed platform 1. When the servo motor 3 is started, it drives the lead screw 4 to rotate continuously. Due to the interaction of the threads, the guide block 5 is forced to move linearly along the axial direction of the lead screw 4. The guide hole 6 is specially opened inside the guide block 5, which perfectly matches the limit rod 16. The top end of the limit rod 16 is firmly fixed to the top of the portal frame 2. The inner wall and bottom end are firmly connected to the fixed platform 1. During the movement of the guide block 5, the guide hole 6 tightly fits the limiting rod 16, and it can only slide smoothly along the vertical direction defined by the limiting rod 16. This effectively avoids radial offset and circumferential sway caused by the rotation of the lead screw 4, ensuring that the guide block 5 can achieve high-precision position adjustment in the vertical direction. In actual winding operation, the copper wire passing through the guide hole 6 can be accurately wound around the designated position of the transformer with the precise movement of the guide block 5, which greatly improves the uniformity and accuracy of the winding. The rotating component includes a drive motor 7 fixedly connected to the bottom of the fixed platform 1. The output end of the drive motor 7 extends to the top of the fixed platform 1 and is fixedly connected to a positioning column 8 through a coupling. A rotating disk 9 is fixedly connected to the outside of the positioning column 8. An annular fixing sleeve 15 for limiting the transformer is fixedly connected to the surface of the rotating disk 9. When the transformer winding operation starts, the drive motor 7... Upon receiving the control signal, the system quickly starts operating. Its output end efficiently transmits power to the positioning column 8 via a coupling. Under the action of the driving force, the positioning column 8 begins to rotate. Since the positioning column 8 and the rotating disk 9 are fixedly connected, the rotation of the positioning column 8 directly drives the rotating disk 9 to rotate synchronously. The annular fixing sleeve 15, which is fixedly connected to the surface of the rotating disk 9, plays a crucial role in the entire rotating assembly. When it is necessary to perform winding operations on the transformer, the transformer is placed inside the annular fixing sleeve 15. The inner diameter of the annular fixing sleeve 15 is carefully designed according to the external dimensions of common transformers, which can tightly fit the outer circumference of the transformer and play a stable limiting role for the transformer. As the rotating disk 9 rotates, the transformer, which is limited by the annular fixing sleeve 15, also performs circumferential motion. This rotational motion allows each part of the transformer to be exposed to the winding operation area in sequence, making it convenient for operators or automated equipment to evenly wind copper wire around different positions of the transformer, greatly improving the efficiency and convenience of winding operations.

[0021] Reference Figure 1 and Figure 4The winding assembly includes two vertical plates 10 fixedly connected to the surface of the fixed platform 1. A forward and reverse motor 11 is fixedly connected to the outside of one of the vertical plates 10. The output end of the forward and reverse motor 11 passes through the vertical plate 10 and is fixedly connected to a rotating shaft 12 via a coupling. A winding roller 13 is fixedly connected to the outside of the rotating shaft 12. Limiting discs 14 are fixedly connected to both ends of the winding roller 13. When the winding operation starts and it is necessary to release or wind up the copper wire, the forward and reverse motor 11 receives a forward rotation command, starts quickly, and begins to run. Its output end is firmly connected to the rotating shaft 12 via a coupling. The rotational power of the motor is precisely transmitted to the rotating shaft 12, driving the rotating shaft 12 to rotate. The take-up roller 13, which is fixedly connected to the outside of the rotating shaft 12, rotates synchronously with the rotating shaft 12. During the winding process, one end of the copper wire passing through the guide hole 6 is fixed on the take-up roller 13. As the take-up roller 13 continues to rotate, the copper wire is gradually released or wound up. The diameter of the limiting plate 14 is larger than that of the take-up roller 13, which can effectively prevent the copper wire from slipping to both sides during the winding process, ensuring that the copper wire is always tightly arranged within the effective winding range of the take-up roller 13, thus ensuring the neatness and tightness of the winding.

[0022] Reference Figure 3 Support legs 17 are fixedly connected to the four corners of the bottom of the fixed platform 1. The four support legs 17 evenly distribute the overall weight of the device, providing a stable support foundation for the device and ensuring that the entire device will not be displaced or shaken due to external interference or vibration caused by the operation of components during the winding operation.

[0023] The implementation principle of a transformer winding device in this application embodiment is as follows: In this application, the drive motor 7 is preferably a YE2132M-4 type, the servo motor 3 is preferably an HBS57 type, and the forward and reverse motor 11 is preferably a TCH(V)22-100-140CB type. The servo motor 3, drive motor 7, and forward and reverse motor 11 are all electrically connected to an external power supply through a switch. The support legs 17 at the four corners of the bottom of the fixed platform 1 provide stable support for the whole, preventing the device from shifting or shaking due to external forces or vibrations of the components. The servo motor 3 is started by the switch, and the servo motor 3 at the top of the gantry frame 2 drives the lead screw 4 to rotate. The thread opening angle of the lead screw 4 is 20 degrees. The thread self-locking condition must meet the following formula: self-locking condition = friction coefficient × tan (helix angle) ≥ 1. The guide block 5, which is threadedly connected to the lead screw 4, moves linearly along the axial direction of the lead screw 4 due to the thread action. At the same time, the guide hole 6 inside the guide block 5 is adapted to the limit rod 16, so that it can only move along the limit rod 16. The guide hole 6 allows for smooth vertical sliding, enabling high-precision position adjustment and precise movement of the copper wire passing through it. This facilitates even and tight winding at the designated position on the transformer. A switch activates the drive motor 7, whose output, via a coupling, rotates the positioning pin 8, located within the transformer's inner ring. This, in turn, drives the rotating disk 9 to rotate synchronously. The annular fixing sleeve 15 on the rotating disk 9 tightly limits the transformer's movement. As the transformer rotates with the rotating disk 9, each part is sequentially exposed in the winding area, facilitating copper wire winding and improving winding efficiency. Regarding the winding assembly, a switch activates the forward / reverse motor 11, receiving forward or reverse commands based on winding requirements. This, via a coupling, drives the rotating shaft 12, causing the winding roller 13 to rotate synchronously. This winds or releases the copper wire passing through the guide hole 6 and fixed to the winding roller 13. Limiting discs 14 at both ends of the winding roller 13 prevent the copper wire from slipping to the sides during winding, ensuring neat and tight winding. All components work together to efficiently and accurately complete the transformer winding operation.
