Detailed Implementation
[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The winding device for a miniature transformer coil involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Reference Figures 1 to 4 As shown, this utility model provides a winding device for a miniature transformer coil, including a body assembly 1, a pushing assembly 2, a rotating assembly 3, a buffer assembly 4, and a fixing assembly 5. The pushing assembly 2 is disposed on one side of the top of the body assembly 1, the rotating assembly 3 is sleeved on one side of the pushing assembly 2, the buffer assembly 4 is installed on one side of the rotating assembly 3, and the fixing assembly 5 is sleeved on the top of the body assembly 1 and inside the rotating assembly 3 respectively.
[0021] Combination Figures 1 to 4 As shown, the buffer assembly 4 includes a fixed column 401, a buffer body 403, a buffer spring 404, and a wire tube 405. The buffer body 403 is movably sleeved inside one side of the fixed column 401. The buffer spring 404 is disposed inside the fixed column 401 at one end of the buffer body 403 along its length. The wire tube 405 is fixedly connected inside the fixed column 401 and abuts against the end of the buffer spring 404. Under the elastic force of the buffer spring 404, it is beneficial to ensure the quality of coil winding when the wire is wound on the miniature transformer. In addition, the design of the wire tube 405 effectively protects the wire from wear or damage during the winding process. At the same time, the wire tube 405 can also guide the wire to wind along a predetermined path, improving the efficiency and accuracy of winding.
[0022] The body assembly 1 includes a base plate 101 and support columns 102, wherein the support columns 102 are fixedly installed on the top of the base plate 101.
[0023] Combination Figures 1 to 3 As shown, the pushing assembly 2 includes a pushing motor 201, a threaded rod 202, a pushing body 203, a slide bar 204, and a fixing block 205. The pushing motor 201 is fixedly sleeved inside the right-side support column 102, and its output shaft is fixedly sleeved to the threaded rod 202 via a coupling. The pushing body 203 is movably sleeved outside the threaded rod 202, and its inner wall has a threaded groove. Slide bars 204 are symmetrically arranged on both sides of the pushing body 203. The fixing block 205 is located on one side of the pushing body 203. After the motor 201 is started, its output shaft drives the transmission shaft to rotate. The transmission shaft causes the threaded rod 202 to rotate, thereby pushing the pushing body 203, slide bar 204, fixing block 205, rotating assembly 3, and buffer assembly 4 to move to the left, ensuring that the wire can be wound evenly.
[0024] Combination Figures 1 to 4 As shown, the rotating assembly 3 includes a rotating motor 301, a gear 302, a fixed shaft 303, a rotating plate 304, and a rack 305. The rotating motor 301 is nested inside the fixed block 205, and the output shaft of the rotating motor 301 is fixedly sleeved with the gear 302 via a coupling. The fixed shaft 303 is movably sleeved inside one side of the pusher 203, and the rotating plate 304 is fixedly sleeved on the outside of the fixed shaft 303. The rack 305 is evenly distributed circumferentially on one side of the rotating plate 304, and the gear 302 meshes with the rack 305. This structure allows the device to rotate after the rotating motor 301 is started, with its output shaft driving the transmission shaft to rotate. The transmission shaft then drives the gear 302 to start rotating, and the gear 302 drives the rack 305 to rotate, thereby causing the rack 305, the rotating plate 304, and the fixed shaft 303 to rotate together, ultimately winding the wires around the miniature transformer.
[0025] Combination Figure 1 , Figure 2 and Figure 4 As shown, the buffer assembly 4 also includes reinforcing rods 402. Several reinforcing rods 402 are fixedly connected between the fixed columns 401. The setting of reinforcing rods 402 not only improves the structural strength between the fixed columns 401, but also enhances the overall stability of the buffer assembly 4, so that the buffer assembly 4 can better withstand the tension from the wire during the winding process, and further ensure the uniformity and compactness of the coil.
[0026] Furthermore, the fixed columns 401 are evenly arranged on the side surface of the rotating plate 304, and the buffer body 403 is movably sleeved inside one side of the fixed columns 401.
[0027] Combination Figure 1 , Figure 2 and Figure 4As shown, the fixing component 5 includes a fixing rod 501, a threaded rod 502, a fixing knob 503, a button 504, a bevel 505, and a fixing spring 506. The fixing rod 501 is fixedly sleeved inside the left support column 102, and a threaded rod 502 is provided on one side of the fixing rod 501. The fixing knob 503 is movably engaged with the outside of the threaded rod 502. The button 504 is symmetrically sleeved inside one side of the rotating plate 304, specifically configured as a movable sleeve, and a bevel 505 is provided on the top of the button 504. The fixing spring 506 is located between the two buttons 504. This structure allows the device to release installation space by rotating and turning the fixing knob 503, facilitating the replacement of the miniature transformer. Next, the wire stake is pushed in from one side of the fixing shaft 303. Using the action of the bevel 505, the fixing spring 506 is compressed by pressing the buttons 504 on both sides. When the button 504 springs up, the wire stake is quickly fixed in place.
[0028] The working principle of this utility model is as follows:
[0029] Based on the correct configuration of the winding device described in this utility model, the first step is to rotate and unscrew the fixing knob 503 to put the equipment in a ready-to-load state for replacing the base component of the miniature transformer that needs to be wound. Next, push the wire stake in from one side of the fixing shaft 303. Under the action of the inclined surface 505, press the buttons 504 on both sides to compress the fixing spring 506 until the buttons 504 pop up, thus quickly completing the fixing of the wire stake. Then, insert one end of the wire into the right wire tube 405 and out from the left wire tube 405. Finally, fix the other end of the wire to one end of the miniature transformer. At this time, the equipment is in a ready-to-wind state that can operate automatically. After confirming that the equipment is powered on and there are no potential operational malfunctions, the operator can start the equipment to begin the winding process.
[0030] The operator uses the necessary control panel or controller structure to operate the equipment. Starting the rotary motor 301, its output shaft drives the transmission shaft to rotate. The transmission shaft causes the gear 302 to rotate, and the movement of the gear 302 in turn drives the rack 305 to rotate. This causes the rack 305, rotating plate 304, and fixed shaft 303 to rotate synchronously, evenly winding the wire around the miniature transformer. Simultaneously, starting the push motor 201, its output shaft drives the transmission shaft to rotate. The transmission shaft causes the threaded rod 202 to rotate, causing the pusher 203, slide bar 204, fixed block 205, rotating assembly 3, and buffer assembly 4 to move to the left, ensuring the uniformity of the wire winding. During the winding process, when the tension is too high, the buffer body 403 will compress into the fixed column 401; when the tension is low, the elastic force of the buffer spring 404 will keep the wire under appropriate tension, thereby ensuring the quality of coil winding. Based on this, the equipment continues to operate until the winding process of the transformer base is completed. After cutting off the excess wire, the loading process of the transformer base is reversed, and the completed transformer can be removed and the next transformer base can be replaced to repeat the winding operation.
[0031] If you need to replace the transformer and wires with different models, simply rotate and unscrew the fixing knob 503, and press the buttons 504 on both sides inward to pull out the transformer and wire stake for replacement.
