Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a winding device for the production of high-frequency switching transformers. Background Technology

[0002] High-frequency switching transformers are the core magnetic components of switching power supplies, operating in the frequency range of tens of kHz to MHz. They utilize high-permeability magnetic cores such as ferrite to achieve efficient power conversion and voltage transformation through rapidly switching currents, while providing electrical isolation. Compared with traditional power frequency transformers, their significant advantages are extremely high power density and conversion efficiency, and a significant reduction in size and weight. They are widely used in various adapters, chargers, and power modules for communication equipment.

[0003] Transformer winding is the core process of precisely winding enameled wire onto a magnetic core frame according to design requirements. The process typically begins with frame preparation, followed by the enameled wire being tightly wound in layers and sections within the frame slots using a winding device or manual operation, with insulating material laid between layers. For multi-winding transformers, each winding must be completed sequentially in a specific order and direction to ensure accurate turn counts and correct terminal alignment. During winding, tension and wire uniformity must be strictly controlled to avoid insulation damage or overlapping. Once the winding is complete, the wire ends are fixed, completing the winding process.

[0004] In the existing technical solutions, the current winding devices have certain problems. For example, the tension of the wire is controlled by manually pulling it during the winding process, which makes it difficult to accurately control the tension of the wire during production and processing, and the wire is prone to loosening or breaking. On the other hand, the traditional winding device is cumbersome to operate when changing the winding mold, which reduces production efficiency. Therefore, we urgently need a winding device for the production of high-frequency switching transformers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of difficulty in controlling tension and cumbersome mold replacement when manually pulling the wire during the winding process in the prior art, and to propose a winding device for the production of high-frequency switching transformers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding device for producing high-frequency switching transformers includes a frame and a drive motor fixedly mounted on the frame. The output end of the drive motor is fixedly connected to a mounting rod. The device further includes: a mounting plate slidably connected to the frame, on which two sets of rollers for wire routing are symmetrically mounted; a second set of rollers for adjusting wire tension is vertically mounted on the mounting plate between the two sets of rollers; a mounting frame fixedly connected to the frame, on which a rotating roller for guiding insulating tape is rotatably connected; an L-shaped rod for supporting the end of the insulating tape is rotatably connected to the mounting frame; and a limiting part fixedly mounted on the frame for positioning the mounting rod.

[0008] To adjust the tension of the guide, preferably, uprights are symmetrically installed on the mounting plate, and each set of uprights has a sliding groove. Both sides of the roller two are slidably connected in the sliding groove. One set of uprights has a rectangular groove, which is connected to the sliding groove. A lead screw is threaded to the bottom wall of the rectangular groove. The lead screw is fixedly connected to the roller two through a slider. When the lead screw rotates, the roller two moves upward and downward.

[0009] Preferably, a handle for operation is fixedly connected to the end of the lead screw.

[0010] To ensure the stability of the rotation of the mounting rod, preferably, the limiting part includes a frame, and a limiting rod coaxial with the mounting rod is threadedly connected inside the frame. The end of the mounting rod is rotatably connected to a limiting plate, and a positioning area is formed when the end of the limiting rod is inserted into the limiting plate.

[0011] To improve the stability of the winding module placement, preferably, the mounting rod is covered with a damping pad to increase friction.

[0012] In order to enable the conductors to be routed on the transformer, preferably, a linear guide rail is slidably connected to the frame, and the mounting plate is slidably connected inside the linear guide rail. When the linear guide rail is working, the mounting plate moves back and forth along the path of the linear guide rail.

[0013] Compared with the prior art, this utility model provides a winding device for the production of high-frequency switching transformers, which has the following advantages:

[0014] 1. This high-frequency switching transformer production winding device, through the setting of a liftable roller two, allows the operator to pass the wire through roller one and roller two in sequence, forming a V-shape. At this time, the operator wraps the end of the wire around one side of the winding module and fixes it. Then, by gripping the handle and turning the screw, the operator moves roller two downward along the slide path. The displacement of roller two is used to compress the wire, thereby increasing the wire tension. When it is necessary to loosen the wire, simply turn the screw counterclockwise to move roller two upward, thereby reducing the wire tension. This allows for quick adjustment of the wire tension during the winding process, preventing the wire from becoming loose or breaking.

[0015] 2. The winding device for high-frequency switching transformer production, through the setting of the L-shaped rod, addresses the issue that during the winding process, after a certain number of turns, insulating tape needs to be wrapped. However, during production, the end of the tape tends to droop downwards, making it inconvenient for operators to retrieve during the next winding. Therefore, operators only need to push the L-shaped rod upwards to support and lift the end of the insulating tape. The operator can then directly pull the insulating tape for the next use without having to retrieve it downwards, thus improving production efficiency.

[0016] 3. The winding device for producing high-frequency switching transformers, through the setting of mounting rods and damping pads, allows operators to simply place the winding module directly onto the mounting rods and use the damping pads to increase the friction between the two to prevent displacement, thereby enabling convenient loading and unloading and effectively improving production efficiency.

[0017] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model avoids the situation where the tension accuracy of the wire is low due to manual pulling, resulting in the wire becoming loose or broken. It is also easier to change the winding mold, thereby improving production efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, 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 utility model 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 utility model.

[0026] Example:

[0027] Reference Figures 1-5 A winding device for producing a high-frequency switching transformer includes a frame 1 and a drive motor 2 fixedly mounted on the frame 1. The output end of the drive motor 2 is fixedly connected to a mounting rod 3. Here, the winding module is directly sleeved on the mounting rod 3. When the winding process is performed, the drive motor 2 starts to drive the transformer to rotate, thereby winding the wires around the transformer.

[0028] It also includes a mounting plate 4 slidably connected to the frame 1. A linear guide rail 19 is slidably connected to the frame 1, and the mounting plate 4 is slidably connected within the linear guide rail 19. When the linear guide rail 19 is working, the mounting plate 4 reciprocates along the path of the linear guide rail 19. Here, according to the attached instruction manual... Figure 1As shown, the linear guide 19 is driven by a motor to perform linear reciprocating motion on the mounting plate 4, and the running trajectory of the linear guide 19 reciprocates along the length direction of the frame 1. Two sets of rollers 5 for cable routing are symmetrically mounted on the mounting plate 4. A roller 6 for adjusting the tension of the wire is raised and lowered between the two sets of rollers 5 on the mounting plate 4. Stands 10 are symmetrically mounted on the mounting plate 4. Both sets of stands 10 are provided with sliding grooves 11. The two sides of the roller 6 are slidably connected in the sliding grooves 11. One set of stands 10 is provided with a rectangular groove 12, and the rectangular groove 12 is connected to the sliding groove 11. A lead screw 13 is threadedly connected to the bottom wall of the rectangular groove 12. The lead screw 13 is fixedly connected to the roller 6 through a slider. A handle 14 for operation is fixedly connected to the end of the lead screw 13. When the lead screw 13 rotates, the roller 6 moves up and down.

[0029] Here, because the wire needs to be taut during winding, before winding, the operator passes the wire through roller 5 and roller 6 in sequence to form a V-shape. Then, the operator wraps the end of the wire around one side of the winding module and fixes it. Then, by turning the screw 13 through the handle 14, the roller 6 moves downward along the path of the slide groove 11. The displacement of the roller 6 is used to press the wire, thereby increasing the wire tension. When it is necessary to loosen the wire, simply turn the screw 13 counterclockwise to move the roller 6 upward, thereby reducing the wire tension. This allows for quick adjustment of the wire tension during the winding process, preventing the wire from becoming loose or breaking.

[0030] It should be noted that the rotation of lead screw 13 can also be driven by a precise motor such as a servo motor, along with necessary sensors to monitor the tension of the wire, and the motor drive can be used to increase or decrease the tension of the wire.

[0031] A mounting bracket 7 is fixedly connected to the frame 1. A rotating roller 8 for guiding the insulating tape is rotatably connected to the mounting bracket 7. An L-shaped rod 9 for supporting the end of the insulating tape is also rotatably connected to the mounting bracket 7. Here, in the winding process, the insulating tape needs to be wound after a certain number of turns of wire. However, during production, the end of the tape will droop downwards, making it inconvenient for the operator to pick it up during the next winding. Therefore, the operator only needs to push the L-shaped rod 9 upwards to support the end of the insulating tape and lift the edge. The operator can then directly pull the insulating tape for the next use without having to pick it up downwards, thereby improving production efficiency.

[0032] A limiting part for positioning the mounting rod 3 is fixedly installed on the frame 1. The limiting part includes a frame 15, and a limiting rod 16 coaxial with the mounting rod 3 is internally threaded to the frame 15. A limiting plate 17 is rotatably connected to the end of the mounting rod 3. When the end of the limiting rod 16 is inserted into the limiting plate 17, a positioning area is formed. The mounting rod 3 is covered with a damping pad 18 to improve friction. Here, the operator only needs to put the winding module directly on the mounting rod 3 and use the damping pad 18 to improve the friction between the two to avoid displacement, thereby realizing convenient loading and unloading and effectively improving production efficiency.

[0033] In this invention, the operator places the winding module onto the mounting rod 3, using the damping pad 18 to improve the installation stability of the winding module. At this time, the limiting rod 16 is rotated via a threaded mechanism, causing its end to abut against the rotatable limiting plate 17. This improves the rotational stability of the mounting rod 3 while preventing the winding module from falling off. The operator then places the required insulating tape on the mounting frame 7, and sequentially passes the ends of the insulating tape through two sets of rotating rollers 8 in a staggered manner. The ends of the insulating tape are then hung on the L-shaped rod 9. Rotating the L-shaped rod 9 to tilt it upwards allows for adjustment of the ends of the insulating tape. After the support is in place, the operator passes the wire in a V-shape through the space formed by roller 5 and roller 6 and fixes the end to the winding module. The operator turns the screw 13 by gripping the handle 14, which in turn drives the stand 10 to move downward along the slide 11. The roller 6 squeezes the wire to increase its tension. When the screw 13 flips and drives the stand 10 to move upward, the wire tension decreases. At this time, the drive motor 2 is started to drive the winding mold on the mounting rod 3 to rotate, and the linear guide rail 19 drives the mounting plate 4 to move back and forth. With the assistance of the operator, the winding process of the transformer is completed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
