Description

Technical Field

[0001] This utility model relates to the field of transformer winding technology, and specifically to a small transformer winding device. Background Technology

[0002] In fields such as electronic equipment, power modules, and small appliances, small transformers are critical power conversion components, and their performance is highly dependent on the precision and consistency of the winding process. The winding process is one of the core steps in transformer manufacturing, and its quality directly affects the transformer's electrical performance and stability.

[0003] Traditional small transformer winding devices typically employ a fixed conductor tension control structure, making it difficult to dynamically adjust the conductor tension during the winding process. This can easily lead to problems such as uneven winding, conductors that are too tight or too loose, thus affecting the coil's tightness and consistency. This problem is particularly pronounced during high-speed winding.

[0004] In addition, existing winding devices usually require manual cutting of the wire after winding, which is not only inefficient, but may also lead to waste or damage of the wire due to improper operation.

[0005] Therefore, it is necessary to design a small transformer winding device that is easy to operate, can automatically adjust the wire tension, and can quickly cut off the wire, so as to improve the winding quality and production efficiency. Utility Model Content

[0006] The technical implementation scheme of this utility model is as follows: A small transformer winding device includes a frame, a winding machine, a winding roller, a telescopic rod, a wire storage frame, an L-shaped frame, a first guide rod, a slider, a spring, and a wire wheel. The winding machine is installed on one side of the top of the frame. The winding machine is equipped with a winding roller and a telescopic rod. The wire storage frame is installed on the telescopic rod. One side of the wire storage frame has an outlet hole communicating with the inner cavity. The L-shaped frame and corresponding first guide rods are symmetrically arranged on both sides of the top of the wire storage frame. The L-shaped frame has longitudinal grooves. The two longitudinal grooves are arranged opposite to each other. A slider is slidably arranged in each of the longitudinal grooves. A spring is arranged between the slider and the transverse part of the L-shaped frame. The spring is wound around the first guide rod. The two sliders are rotatably connected to the wire wheel through the transverse rod. The wire wheel is arranged opposite to the outlet hole. The wire in the wire storage frame is wound around the wire wheel through the outlet hole.

[0007] Furthermore, a U-shaped frame is provided between the two sliders, and a wire tube for the wire to pass through is installed on the U-shaped frame. The wire wound around the wire wheel passes through the wire tube.

[0008] Furthermore, a rectangular frame is installed on the conduit, and the conduit divides the rectangular frame into two symmetrical halves. A second guide rod is slidably mounted on the side of the rectangular frame facing away from the conduit. The ends of the second guide rods that extend into the rectangular frame are connected to a rubber block. A through hole is provided on the conduit for the rubber block to pass through. The ends of the second guide rods located outside the rectangular frame are connected to an inverted T-shaped plate. A second spring is installed between the inverted T-shaped plate and the rubber block. The second spring is wound around the second guide rod. A dual-axis motor is installed on the rectangular frame. A lead screw is connected to the output shaft of the dual-axis motor. The lead screw thread passes through the inverted T-shaped plate.

[0009] Furthermore, Z-shaped frames are symmetrically arranged on the U-shaped frame, and electric slide rails are arranged between the Z-shaped frames. Z-shaped carriages are slidably connected on the electric slide rails. A blade is arranged at the end of the Z-shaped carriage away from the electric slide rail, and a knife holder is arranged at the end of the Z-shaped frame away from the U-shaped frame. The electric slide rail drives the blade to insert into the knife holder through the Z-shaped carriage to cut the wire.

[0010] Furthermore, one tool holder has a U-shaped groove for the Z-shaped slide to slide into so that the blade is completely placed inside the tool holder, and the other tool holder has a cavity for the insertion of part of the tool holder.

[0011] Furthermore, a collection box is installed on the rack.

[0012] The present invention has the following advantages: 1. By moving the slider up and down along the longitudinal groove of the L-frame, the pressure applied by the wire to the wire wheel is adjusted by the cooperation of the slider and the spring to make the wire wheel rise and fall, thereby adapting to different tensions of the wire. This achieves the effect of automatically adjusting the wire tension according to the tension change during the winding process, thereby avoiding the wire being too tight or too loose, ensuring uniform and tight winding, and improving the quality of the coil.

[0013] 2. A dual-axis motor drives a rubber block to clamp the wire, and an electric slide rail and blade are used to achieve automatic cutting, reducing manual intervention, improving production efficiency, and avoiding wire waste or damage caused by manual operation.

[0014] 3. This device has the advantages of simple structure and convenient operation. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Example 1

[0023] A small transformer winding device, such as Figure 1-3 As shown, the device includes a frame 1, a winding machine 2, a winding roller 3, a telescopic rod 4, a wire storage frame 5, an L-shaped frame 6, a first guide rod 61, a slider 7, a spring 8, and a guide wheel 9. The frame 1 supports the entire device. The winding machine 2 is mounted on one side of the top of the frame 1. A winding roller 3 and a telescopic rod 4 are arranged diagonally on the winding machine 2. The winding roller 3 is used to mount a small transformer that needs to be wound. The wire storage frame 5 is mounted on the telescopic rod 4. The wire storage frame 5 has a wire outlet hole 51 that communicates with the inner cavity of the wire storage frame 5 on the side facing the winding roller 3. The L-shaped frame 6 and the corresponding first guide rod 61 are symmetrically arranged on both sides of the top of the wire storage frame 5. The L-shaped frame 6 and the first guide rod 61 are located on the side of the wire storage frame 5 near the winding roller 3. The L-frame 6 has longitudinal grooves, with two longitudinal grooves facing each other. Each longitudinal groove has a slider 7 that slides within it. The slider 7 moves vertically up and down along the longitudinal groove. A spring 8 is provided between the slider 7 and the transverse part of the L-frame 6. The spring 8 is wound around the first guide rod 61. A guide wheel 9 is rotatably connected between the two sliders 7 through a transverse rod. The guide wheel 9 is facing the wire outlet hole 51. The wire in the wire storage frame 5 passes through the wire outlet hole 51 and is wound onto the guide wheel 9. After passing around the guide wheel 9, it connects to the frame of the small transformer mounted on the winding roller 3. Through the rotation of the winding roller 3 and the extension and retraction of the telescopic rod 4, the wire is quickly and evenly wound onto the frame of the transformer.

[0024] like Figure 2 and Figure 4 As shown, a U-shaped frame 10 is provided between the two sliders 7. A wire tube 11 for wires to pass through is installed on the U-shaped frame 10. The wires wound around the wire wheel 9 pass through the wire tube 11. The wire tube 11 is used to further guide the wires to the transformer frame on the winding roller 3.

[0025] like Figure 1 As shown, a collection frame 52 is provided on the frame 1. The transformer that has completed winding can be easily placed in the collection frame 52 for collection after being removed from the winding roller 3.

[0026] In use, the transformer to be wound is movably mounted on the winding roller 3; the wire in the wire storage frame 5 is led out through the wire outlet hole 51 on the side wall, guided by the wire wheel 9, passes through the wire tube 11, and is finally delivered to the transformer skeleton on the winding roller 3, so that the wire rotates multiple times along the transformer skeleton to effectively connect the movable end of the wire to the transformer; then, the winding machine 2 drives the winding roller 3 to rotate, and at the same time the telescopic rod 4 pushes the wire storage frame 5 to move along the axis, so that the wire is quickly and evenly wound on the transformer skeleton to form a coil; when the wire is wound at high speed along the transformer skeleton, the tension increases when the wire passes the wire wheel 9, and the wire will pull the wire wheel 9 down, thereby driving the slider 7 to move down along the longitudinal groove of the L frame 6 and compress the spring 8. Conversely, when the tension decreases when the wire passes the wire wheel 9, the slider 7 moves up along the longitudinal groove of the L frame 6 under the action of the spring force of the spring 8, thereby tightening the wire. The tension of the wire is dynamically balanced by the cooperation of the spring 8 and the slider 7, avoiding the wire being too tight or too loose, thus providing convenience for the winding operation.

[0027] Example 2

[0028] Based on Example 1, such as Figure 2 , Figure 4 and Figure 5As shown, a rectangular frame 111 is installed on the conduit 11. The rectangular frame 111 is divided into two symmetrical halves by the conduit 11. A second guide rod 15 is slidably mounted side by side on the side of the rectangular frame 111 facing away from the conduit 11. The ends of the second guide rods 15 extending into the rectangular frame 111 are connected to a rubber block 16. A through hole is provided on the conduit 11 for the rubber block 16 to pass through. The size of the through hole is adapted to the size of the rubber block 16. The ends of the second guide rods 15 located outside the rectangular frame 111 are connected to an inverted T-shaped plate 14. A spring is provided between the inverted T-shaped plate 14 and the rubber block 16. 7. Spring 17 is wound around the second guide rod 15. A dual-axis motor 12 is installed on the rectangular frame 111 through an inverted L-shaped connecting plate. A lead screw 13 is connected to the output shaft of the dual-axis motor 12. The lead screw 13 is threaded through the inverted T-shaped plate 14. When the dual-axis motor 14 is working, the inverted T-shaped plate 14 moves along the lead screw 13 and compresses the spring 17. The pressure generated by the deformation of the spring 17 drives the rubber block 16 to move into the inner cavity of the wire tube 11. At the same time, the second guide rod 15 is pulled towards the guide tube 11. When the two rubber blocks 16 abut in the wire tube 11, the wire can be clamped.

[0029] like Figure 2 and Figure 4 As shown, Z-shaped frames 1001 are symmetrically arranged on the U-shaped frame 10. An electric slide rail 18 is arranged between the Z-shaped frames 1001. A Z-shaped carriage 1002 is slidably connected on the electric slide rail 18. A blade 19 is provided at the end of the Z-shaped carriage 1002 away from the electric slide rail 18. A knife holder 20 is provided at the end of the Z-shaped frame 1001 away from the U-shaped frame 10. The electric slide rail 18 drives the blade 19 to insert into the knife holder 20 through the Z-shaped carriage 1002 to cut the wire.

[0030] like Figure 4 As shown, one tool holder 20 has a U-shaped groove for the Z-shaped slide 1002 to slide into so that the blade 19 is completely placed inside the tool holder 20. This setting makes it easy to hide the blade 19 when not in use, thereby protecting the operator. The other tool holder 20 has a cavity for the blade holder 20 to be partially inserted. When the blade 19 is inserted into the cavity, the wire can be cut.

[0031] After the winding operation is completed, the dual-axis motor 12 is powered on and drives the lead screw 13 to rotate, thereby moving the inverted T-shaped plate 14 towards the wire tube 11 and compressing the second spring 17. After the second spring 17 is deformed by the pressure, it drives the rubber block 16 to pass through the through hole. When the rubber blocks 16 on both sides contact and press together, the wire is clamped between the two rubber blocks 16, thereby fixing the position of the wire. At this time, the electric slide rail 18 is powered on and drives the Z-shaped slide 1002 to move horizontally, thereby causing the blade 19 to move from one blade holder 20 to the other blade holder 20. When the blade 19 inserts into the internal cavity of the blade holder 20, the wire is cut, thereby realizing the rapid cutting operation of the wire. Finally, the transformer that has completed the winding operation is removed from the winding roller 3 and placed in the collection frame 52 for collection.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
