Description

Technical Field

[0001] This invention relates to the field of transformer winding technology, and more particularly to a high-frequency transformer winding machine. Background Technology

[0002] Electronic devices have permeated every aspect of our lives, but the power standards of different electronic devices vary, so transformers are needed. A transformer is a device that uses electromagnetic inductance to transform AC voltage, current and impedance. A transformer consists of a magnetic core and coils.

[0003] There are many winding methods for transformers, the most common being close winding and uniform winding. Regardless of whether it is close winding or uniform winding, it is required to ensure that the wires are wound in an orderly and equidistant manner during winding. Due to their small size and many models, high-frequency transformers are mostly manufactured manually using existing technology. Since the uniformity of the wires wound on the coil shaft directly affects the performance of the high-frequency transformer, skilled operators are required to perform the winding operation manually in order to ensure product quality. Manual winding is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of time-consuming and labor-intensive manual winding in the prior art, and the inability of manual winding to guarantee the uniformity of winding, and to propose a high-frequency transformer winding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-frequency transformer winding machine includes a mounting plate, wherein the mounting plate is provided with:

[0007] A winding assembly, comprising a motor, an output shaft, and a rotating disk arranged coaxially, wherein one end of the output shaft is fixedly connected to the output end of the motor and the other end is fixedly connected to the rotating disk, and the rotating disk is provided with a support mechanism for supporting the transformer core;

[0008] The evenly spaced component includes a mounting bracket slidably mounted on a mounting plate. A rotating column is rotatably mounted on the mounting bracket. A fixed disk is fixedly mounted on the rotating column, and a movable disk is slidably mounted on the rotating column. The movable disk and the fixed disk are connected by a thick spring. A pressure groove is formed on the outer edge of the thick spring. The rotating column is connected to the output shaft through a transmission mechanism. When the output shaft rotates, it drives the magnetic core to wind simultaneously, causing the thick spring to rotate synchronously and making the copper wire evenly wound according to the pitch of the thick spring.

[0009] Preferably, the support mechanism includes a plurality of telescopic rods slidably disposed on the circumference of the rotating disk, wherein a pressure rod is fixedly disposed at the end of each telescopic rod, and the plurality of pressure rods are connected by a telescopic structure.

[0010] Preferably, the outer side of the pressure bar is provided with an anti-slip strip.

[0011] Preferably, the telescopic structure includes a first cylinder fixedly mounted on a rotating disk, and the telescopic ends of the first cylinder are rotatably connected to a pressing rod via connecting rods.

[0012] Preferably, the mounting plate has two parallel longitudinally arranged sliding grooves, and a slider is fixedly provided at the bottom of the mounting bracket, the slider being slidably connected to the sliding grooves.

[0013] Preferably, it further includes an adjustment mechanism, which includes an adjustment knob rotatably mounted on the movable disk. The adjustment knob is threadedly connected to the rotating column. By rotating the adjustment knob, the distance between the movable disk and the fixed disk can be changed, thereby changing the pitch of the coarse spring.

[0014] Preferably, it further includes a limiting mechanism, which includes a limiting block fixedly disposed on the inner wall of the movable disk, and a limiting groove slidably connected to the limiting block on the rotating column.

[0015] Preferably, the transmission mechanism includes a fixed pulley fixedly sleeved on the output shaft and the rotating column, a vertically arranged second cylinder fixedly mounted on the mounting plate, a U-shaped housing fixedly mounted on the telescopic end of the second cylinder, a movable pulley rotatably mounted inside the housing, and the two fixed pulleys and the movable pulley are connected by belt drive.

[0016] Preferably, the transmission mechanism further includes a pressure plate fixedly mounted on the mounting bracket, the pressure plate having an inclined sliding opening, and a sliding rod fixedly mounted on the housing, the sliding rod extending into the sliding opening and abutting against the sliding opening.

[0017] Preferably, the axes of the fixed disk and the rotating disk are located on the same horizontal plane, so that the cross section of the thick spring is tangent to the surface of the magnetic core.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This invention utilizes a thick spring and a pressure groove on the thick spring. During transformer winding, the thick spring is brought close to the magnetic core, causing the pressure groove to press the wire against the magnetic core. As the wire is wound, the thick spring rotates synchronously, causing the wire to wind along the pressure groove on the surface of the magnetic core. This ensures that the spacing of the wire winding is uniform and improves the winding quality. At the same time, the pressure groove has a guiding effect on the wire, reducing the looseness of the wire winding and improving product quality. This invention solves the problems of time-consuming and labor-intensive manual winding in the prior art, and the inability to guarantee the uniformity of the winding.

[0020] 2. By setting an adjustment mechanism, the pitch of the coarse spring can be changed by rotating the adjustment knob, thereby changing the conductor spacing during transformer winding. It is applicable to different winding methods of high-frequency transformers such as close winding and uniform winding, and has greater practicality. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Reference Figure 1-2 A high-frequency transformer winding machine includes a mounting plate 1, on which a winding assembly 2 and a spacing assembly 3 are provided.

[0031] Reference Figure 3-4 The winding assembly 2 includes a motor 4, an output shaft 5, and a rotating disk 6 arranged coaxially. One end of the output shaft 5 is fixedly connected to the output end of the motor 4, and the other end is fixedly connected to the rotating disk 6. The output shaft 5 and the rotating disk 6 are driven to rotate by the rotation of the motor 4. The rotating disk 6 is provided with a support mechanism for supporting the transformer core and fixing the movable end of the wire to the core. When the rotating disk 6 rotates, it drives the core to rotate, so that the wire is wound on the core.

[0032] Reference Figure 3-4 The uniform pitch component 3 includes a mounting bracket 7 slidably mounted on the mounting plate 1. A rotating column 8 is rotatably mounted on the mounting bracket 7. The rotating column 8 is coaxially mounted with the mounting bracket 7 and parallel to the output shaft 5, so that the rotating column 8 remains parallel to the magnetic core when it rotates. A fixed disk 9 is fixedly mounted on the rotating column 8, and a movable disk 10 is slidably mounted on the rotating column 8. The movable disk 10 and the fixed disk 9 are connected by a coarse spring 11. The outer edge of the coarse spring 11 has a pressing groove 12. When winding the wire, the wire is clamped in the pressing groove 12 and pressed against the surface of the magnetic core. The rotating column 8 and the output shaft 5 are connected by a transmission mechanism. When the output shaft 5 rotates, it drives the magnetic core to wind the wire and drives the rotating column 8 to rotate, so that the coarse spring 11 rotates synchronously and the copper wire is wound evenly according to the pitch of the coarse spring 11.

[0033] This invention utilizes the helical characteristics of the coarse spring 11, in conjunction with the pressure groove 12, to limit the wire during winding. As the wire rotates along the contact path between the coarse spring 11 and the magnetic core, the contact point between the coarse spring 11 and the magnetic core moves to one side, making the winding more uniform. Furthermore, the pressure groove 12 guides the wire, reducing the looseness of the winding and preventing the wire from becoming misaligned, thus improving product quality. This invention solves the problems of time-consuming and labor-intensive manual winding in the prior art, and the inability to guarantee the uniformity of the winding.

[0034] Referring to 1-2, the axes of the fixed disk 9 and the rotating disk 6 are located on the same horizontal plane, so that the cross section of the thick spring 11 is tangent to the surface of the magnetic core, which facilitates the contact between the thick spring 11 and the magnetic core and helps the thick spring 11 to restrict the wire.

[0035] Reference Figure 1-2 The support mechanism includes multiple telescopic rods that are equidistantly arranged on the circumference of the rotating disk 6. Each telescopic rod has a pressing rod 13 fixed at its end. The multiple pressing rods 13 are connected by a telescopic structure. The center of the magnetic core is fixed by the expansion of the multiple pressing rods 13, which is beneficial to the stable installation of the magnetic core.

[0036] Reference Figure 1-2 An anti-slip strip 14 is provided on the outer side of the pressure rod 13 to increase the friction between the pressure rod 13 and the inner wall of the magnetic core, making the installation of the magnetic core more stable.

[0037] Reference Figure 1-2 The telescopic structure includes a first cylinder 15 fixedly mounted on the rotating disk 6. The telescopic ends of the first cylinder 15 are rotatably connected to the pressing rod 13 via a connecting rod 16. By telescopically extending or retracting the first cylinder 15, the pressing rod 13 is simultaneously expanded or retracted by the connecting rod 16, which facilitates the installation of the magnetic core and is applicable to different types of magnetic cores, thus improving practicality.

[0038] Reference Figure 5 It also includes an adjustment mechanism, which includes an adjustment knob 17 rotatably mounted on the movable disk 10. The adjustment knob 17 is threadedly connected to the rotating column 8. By rotating the adjustment knob 17, the adjustment knob 17 can be moved along the length direction of the rotating column 8 without the movable disk 10 rotating, thereby changing the distance between the movable disk 10 and the fixed disk 9 and changing the pitch of the coarse spring 11.

[0039] By changing the pitch of the coarse spring 11, the spacing of the wire during winding can be altered to accommodate different winding methods such as close winding and even winding, thus broadening its applicability.

[0040] Reference Figure 5 It also includes a limiting mechanism, which includes a limiting block 18 fixedly installed on the inner wall of the movable disk 10. A limiting groove 19 is provided on the rotating column 8 and is slidably connected to the limiting block 18. By cooperating with the limiting block 18 and the limiting groove 19, the movable disk 10 can only move along the length direction of the rotating column 8, reducing the risk that the movable disk 10 will rotate around the rotating column 8 and cause the coarse spring 11 to twist.

[0041] Reference Figure 1-2 The mounting plate 1 has two parallel longitudinally arranged sliding grooves. The bottom end of the mounting bracket 7 is fixedly provided with a slider, which is slidably connected to the sliding groove, so that the mounting bracket 7 can slide in the sliding groove with the slider to change the distance between the coarse spring 11 and the magnetic core.

[0042] Reference Figure 6 The transmission mechanism includes a fixed pulley fixedly sleeved on the output shaft 5 and the rotating column 8. A vertically arranged second cylinder 20 is fixedly installed on the mounting plate 1. A U-shaped housing 21 is fixedly installed at the telescopic end of the second cylinder 20. A movable pulley is rotatably installed inside the housing 21. By telescopically extending the second cylinder 20, the position of the movable pulley can be changed. The two fixed pulleys and the movable pulley are connected by belt drive. Since the belt length remains unchanged, the mounting frame 7 moves closer to the output shaft 5 along with the fixed pulley, which in turn moves the rotating column 8 closer to the output shaft 5, changing the distance between the coarse spring 11 and the magnetic core. This facilitates the installation and removal of the magnetic core and allows for adjustment for magnetic cores of different diameters, ensuring that the coarse spring 11 fits against the surface of the magnetic core.

[0043] Reference Figure 6 The transmission mechanism also includes a pressure plate 22 fixedly mounted on the mounting frame 7. The pressure plate 22 has an inclined sliding opening 23. A sliding rod 24 is fixedly mounted on the housing 21. When the second cylinder 20 drives the housing 21 to move up and down, the housing 21 drives the sliding rod 24 to move up and down. The sliding rod 24 extends into the sliding opening 23 and abuts against the sliding opening 23. When the sliding rod 24 moves up and down, it will press against the sliding opening 23. Since the sliding opening 23 is inclined, when the sliding rod 24 moves up and down, it will cause the mounting frame 7 to drive the slider to slide left and right synchronously along the sliding groove, so that the belt is always in a taut state, and the belt is effectively transmitted.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
