Description

Technical Field

[0001] This utility model relates to the field of automatic winding technology, and in particular to an automatic winding mechanism for an inductor winding machine. Background Technology

[0002] Inductor winding machines are widely used in electronic equipment manufacturing, power systems, communication engineering, new energy and other fields to manufacture various types of inductor components to meet the inductor performance requirements of different circuits.

[0003] In the prior art, such as the automatic winding mechanism for an inductor winding machine proposed in patent 202421157050.6, the longitudinal movable frame on the outside of the winding drum is moved up or down. The longitudinal movable frame drives the wire fixing sleeve. When the diameter of the copper wire coil changes, the inner ring on the inner side of the wire fixing sleeve is squeezed inward, so that the overall diameter of the wire fixing sleeve becomes smaller. In this way, the radius of the winding coil is determined in advance. However, during the winding process of the inductor winding machine, the wire is easy to become loose and unevenly stacked, resulting in an irregular shape of the wound coil, which affects the appearance and assembly of the inductor. Therefore, in order to solve this problem, we propose an automatic winding mechanism for an inductor winding machine. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic winding mechanism for an inductor winding machine, which can ensure tight and orderly winding and achieve uniform stacking, effectively solve the problems of looseness and uneven stacking, improve the regularity of coil shape and inductor assembly performance, and adjust the second bolt by rotating it in the opposite direction. The extrusion plate drives the damping sleeve to recover part of the deformation, reducing the damping force. By adjusting the second bolt, the tightness of the damping sleeve can be changed, which can adapt to working conditions with different tension change frequencies and amplitudes.

[0005] To achieve the above objectives, an automatic winding mechanism for an inductor winding machine is provided, comprising a worktable, with fixed plates fixedly mounted on both sides of the upper part of the worktable. A winding drum is movably fitted inside the fixed plates. A support frame is fixedly mounted above the worktable, with a support shaft fixedly mounted inside the support frame. A first guide wheel is movably fitted outside the support shaft. A sliding groove is formed inside the support frame, and multiple limiting holes are formed at the rear end of the sliding groove. A first support plate is movably fitted inside the sliding groove, and two first bolts are fitted inside the first support plate, with the first bolts extending to the rear end of the support frame. The first support plate is connected with a first nut. Two springs are fixedly installed above the first support plate. A second support plate is fixedly connected above the springs. A second guide wheel is installed in the movable sleeve inside the second support plate. A third support plate is installed in the movable sleeve inside the slide groove. A third guide wheel is installed in the movable sleeve inside the third support plate. Two second bolts are installed inside the second support plate. One end of the second bolt extends to the outside of the second support plate and is fixedly connected to a pressing plate. A damping sleeve is installed in the movable sleeve on one side of the pressing plate outside the second bolt. A limit plate is threadedly connected to one side of the damping sleeve outside the second bolt.

[0006] According to the automatic winding mechanism for an inductor winding machine, a motor is fixedly installed on one side of the fixed plate, and the output shaft of the motor is fixedly connected to the winding drum.

[0007] According to the automatic winding mechanism for an inductor winding machine, two third bolts are installed inside the third support plate, and the third bolts extend to the rear end of the support frame and are threadedly connected to a second nut.

[0008] According to the automatic winding mechanism for an inductor winding machine, the extrusion plate, damping sleeve, and limiting plate are disposed inside the slide groove.

[0009] According to the automatic winding mechanism for an inductor winding machine, the outer surface of the damping sleeve is in close contact with the inner wall of the slide groove, and the outer surface of the limiting plate is in close contact with the inner wall of the slide groove.

[0010] According to the automatic winding mechanism for an inductor winding machine, the limiting holes are evenly distributed along the length direction of the slide groove.

[0011] According to the automatic winding mechanism for an inductor winding machine, the limiting hole is circular in shape, and the diameter of the limiting hole is adapted to the diameters of the first bolt and the third bolt.

[0012] According to the automatic winding mechanism for an inductor winding machine, the groove depths of the first guide wheel, the second guide wheel, and the third guide wheel are the same, and the grooves of the first guide wheel, the second guide wheel, and the third guide wheel are U-shaped. Beneficial effects

[0013] 1. By setting a first guide wheel, a second guide wheel, and a third guide wheel with the same groove depth and a U-shape, a three-level guiding constraint is formed for the winding. At the same time, the second guide wheel is elastically connected to the first support plate through a spring, which can adaptively adjust the pressure according to the winding tension. Combined with the position adjustment mechanism of the sliding groove limit hole and the bolt nut, it can ensure that the winding is tight and orderly, and achieve uniform stacking, effectively solving the problems of looseness and uneven stacking, and improving the regularity of the coil shape and the inductor assembly performance.

[0014] 2. When the second support plate slides in the groove, the limiting plate acts as a guide. When it is necessary to increase the damping, use a tool to rotate the second bolt. The second bolt pushes the extrusion plate to move towards the damping sleeve. The extrusion plate extrudes the damping sleeve, causing the damping sleeve to deform and increasing the friction with the inner wall of the groove, thereby increasing the damping force. When it is necessary to reduce the damping, rotate the second bolt in the opposite direction to adjust it. The extrusion plate drives the damping sleeve to recover part of its deformation, and the damping force decreases. By adjusting the second bolt to change the tightness of the damping sleeve, it can be adapted to working conditions with different tension change frequencies and amplitudes.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses an automatic winding mechanism for an inductor winding machine, comprising a worktable 1 for easy winding. Fixed plates 2 are fixedly installed on both sides of the upper part of the worktable 1, allowing a winding drum 3 to be wound. The winding drum 3 is movably fitted inside the fixed plates 2. A support frame 4 is fixedly installed above the worktable 1, providing stable support. A support shaft 5 is fixedly installed inside the support frame 4, supporting the rotation of a first guide wheel 6. The first guide wheel 6 is movably fitted outside the support shaft 5. The support frame 4 has an internal opening... A sliding groove 7 is provided to facilitate the sliding of the second support plate 13. Multiple limiting holes 8 are provided at the rear end of the sliding groove 7 to facilitate the adjustment of the first support plate 9. The first support plate 9 is movably fitted inside the sliding groove 7, providing support for the spring 12. Two first bolts 10 are fitted inside the first support plate 9, facilitating its adjustment. The first bolts 10 extend to the rear end of the support frame 4 and are threaded with a first nut 11, which limits the movement of the first support plate 9. Two springs 12 are fixedly installed on the top of the first support plate 9. The second guide wheel 14 can move using the good elasticity of spring 12. A second support plate 13 is fixedly connected above spring 12, which supports the movement of the second guide wheel 14. The second guide wheel 14 is housed in a movable sleeve inside the second support plate 13. The position of the second guide wheel 14 can be adjusted by the extension and retraction of spring 12, thereby maintaining the stability of the guide tension. A third support plate 15 is movably fitted inside the slide groove 7, which supports the movement of the third guide wheel 16. The third guide wheel 16 is movably fitted inside the third support plate 15. The three guide pulleys 16 can provide tension to the line. Two second bolts 17 are installed inside the second support plate 13. The second bolts 17 can drive the extrusion plate 18 to move. One end of the second bolt 17 extends to the outside of the second support plate 13 and is fixedly connected to the extrusion plate 18. The extrusion plate 18 can extrude the damping sleeve 19. The damping sleeve 19 is movable on one side of the extrusion plate 18 outside the second bolt 17. The damping sleeve 19 can increase the friction. The limit plate 20 is threaded on one side of the damping sleeve 19 outside the second bolt 17. The limit plate 20 can limit the second bolt 17 and the second support plate 13.

[0025] Specifically: A motor 21 is fixedly installed on one side of the fixed plate 2. The output shaft of the motor 21 is fixedly connected to the winding drum 3. The motor 21 can drive the winding drum 3 to rotate.

[0026] Specifically: The third support plate 15 has two third bolts 22 installed inside. The third bolts 22 extend to the rear end of the support frame 4 and are threaded with a second nut 23. By adjusting the second nut 23, the position of the third support plate 15 in the slide groove 7 can be adjusted, thereby changing the height and position of the third guide wheel 16 to adapt to different winding requirements.

[0027] Specifically: the extrusion plate 18, the damping sleeve 19, and the limiting plate 20 are disposed inside the slide groove 7. The sliding speed of the second support plate 13 can be controlled by the extrusion plate 18, the damping sleeve 19, and the limiting plate 20 disposed inside the slide groove 7.

[0028] Specifically: the outer surface of the damping sleeve 19 is in close contact with the inner wall of the slide groove 7, and the outer surface of the limiting plate 20 is in close contact with the inner wall of the slide groove 7. Through the close contact between the outer surface of the damping sleeve 19 and the inner wall of the slide groove 7, and the close contact between the outer surface of the limiting plate 20 and the inner wall of the slide groove 7, the second support plate 13 can be limited while effectively suppressing the violent shaking of the second guide wheel 14 caused by the change of wire tension, thereby further improving the accuracy and stability of winding.

[0029] Specifically: the limiting holes 8 are evenly distributed along the length of the slide groove 7, and the limiting holes 8 can be used to flexibly adjust and fix the position of the first support plate 9 and the third support plate 15.

[0030] Specifically: the limiting hole 8 is circular in shape, and the diameter of the limiting hole 8 is adapted to the diameter of the first bolt 10 and the third bolt 22. By adapting the diameter of the limiting hole 8 to the diameter of the first bolt 10 and the third bolt 22, the first support plate 9 and the third support plate 15 can be adjusted according to the actual winding requirements.

[0031] Specifically: the groove depths of the first guide wheel 6, the second guide wheel 14, and the third guide wheel 16 are the same, and the grooves of the first guide wheel 6, the second guide wheel 14, and the third guide wheel 16 are U-shaped. The grooves of the first guide wheel 6, the second guide wheel 14, and the third guide wheel 16 can provide good positioning and guidance for the wire, ensuring that the wire always stays on the correct path during the winding process and avoiding problems such as tangling and knotting of the wire.

[0032] Working principle: During use, motor 21 starts, and its output shaft drives the winding drum 3 to rotate, thus providing a power source for winding. During the winding process, the wire passes through the first guide wheel 6, the second guide wheel 14, and the third guide wheel 16 in sequence. Since the grooves of the three guide wheels have the same depth and are U-shaped, they can form a three-level guiding constraint on the winding, effectively regulating the direction of the wire. At the same time, the second guide wheel 14 is elastically connected to the first support plate 9 through spring 12. When the winding tension changes, the second guide wheel 14 can adaptively adjust the pressure under the action of spring 12. If the winding tension increases, spring 12 is stretched and the second guide wheel 14 moves upward; if the tension decreases, spring 12 is compressed and the second guide wheel 14 moves downward, thus ensuring the relative stability of the tension during the winding process, thereby ensuring tight and orderly winding. In addition, multiple equally spaced limiting holes 8 are distributed at the rear end of the slide groove 7. The first support plate 9 and the third support plate 15 can move within the slide groove 7 through the first bolt 10 and the first nut 1. The engagement of the first support plate 9 and the third support plate 15 with the third bolt 22, the second nut 23 and the limiting hole 8 can adjust the position of the first support plate 9 and the third support plate 15, thereby adjusting the height of the second guide wheel 14 and the third guide wheel 16, achieving uniform stacking of the winding, effectively solving the problems of looseness and uneven stacking, improving the regularity of the coil shape and the inductor assembly performance. When the second support plate 13 slides in the slide groove 7, the limiting plate 20 plays a guiding role. When it is necessary to adapt to different tension change frequencies and amplitudes, the tightness of the damping sleeve 19 can be changed by adjusting the second bolt 17. In specific operation, the second bolt 17 is rotated with a tool. The second bolt 17 pushes the extrusion plate 18 to move towards the damping sleeve 19. The extrusion plate 18 extrudes the damping sleeve 19, causing it to deform and increasing the friction with the inner wall of the slide groove 7, thereby increasing the damping force. If it is necessary to reduce the damping, the second bolt 17 is rotated in the opposite direction to adjust the damping force. The extrusion plate 18 drives the damping sleeve 19 to recover part of the deformation, and the damping force decreases accordingly.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
