Description

Technical Field

[0001] This utility model relates to the field of coil winding technology, and in particular to a solenoid valve coil winding device. Background Technology

[0002] In the field of solenoid valve coil production, traditional winding devices have significant technical limitations. Early manual winding relied entirely on manual operation, and the uniformity of wire arrangement and tension control lacked stable standards, resulting in loose coil structures and large fluctuations in electrical performance, making it difficult to meet the consistency requirements of industrial-grade products. Although semi-automatic winding equipment automates the spindle rotation, the wire arrangement process still requires manual intervention, and the mechanical structure needs to be manually adjusted when changing to different specifications of bobbins, resulting in low changeover efficiency and only being able to adapt to regular-shaped bobbins. When dealing with irregular structures, it is difficult to accurately control the wire winding trajectory, often resulting in overlapping wires or gaps. Although fully automatic winding equipment improves the degree of automation, the rigid wire arrangement mechanism is not adaptable enough to bobbin processing errors or tension changes during the winding process. When operating at high speeds, wire breakage or coil deformation is prone to occur. When winding multiple layers, poor interlayer adhesion affects heat dissipation and inductance performance. In addition, traditional devices have limited compatibility with wires of different diameters, require frequent equipment maintenance, and are costly, making it difficult to meet the needs of modern production with multiple varieties and small batches, as well as the high-precision requirements of high-end solenoid valve coils. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide a solenoid valve coil winding device that can solve the existing problems of accuracy, efficiency and adaptability.

[0005] To solve the above technical problems, this utility model provides a solenoid valve coil winding device, which adopts the following technical solution: it includes a base, and support rods are fixedly connected to the left and right sides of the top of the base. A first mounting frame is fixedly connected to the right side of the left support rod near the bottom. A first drive motor is arranged inside the first mounting frame. A threaded rod is fixedly connected to the output end of the first drive motor. A winding position dynamic adaptation mechanism is arranged on the outer surface of the threaded rod. A second mounting frame is fixedly connected to the right side of the left support rod near the top. A second drive motor is arranged inside the second mounting frame. The output end of the second drive motor extends to the right side of the second mounting frame and is fixedly connected to an insertion block. A winding mechanism is inserted into the right side of the insertion block. The winding mechanism includes a winding roller, a protrusion, a connecting rod, a limiting plate, a first sliding groove, a second slider, and a first spring; The dynamic adaptation mechanism for winding position includes a first slider, a guide wheel, a second slide groove, a second guide rod, a second spring, a third slider, a fixed shaft, and a mounting groove.

[0006] Optionally, the left side of the winding roller is inserted into the insert block, the right side of the insert block is threaded into the connecting rod, and the right end of the connecting rod passes through the winding roller and is fixedly connected to the limiting plate.

[0007] The above technical solution achieves bidirectional positioning of the winding drum, ensuring stable power transmission from the second drive motor to the drum while preventing axial movement of the drum during rotation, thus providing structural support for winding accuracy.

[0008] Optionally, the outer surface of the connecting rod near the right end is rotatably connected to the groove at the top of the right support rod, and the left side of the limiting plate is tightly fitted to the right side of the right support rod.

[0009] The above technical solution, through the rotational support of the groove on the right side support rod and the power connection of the left side insert block, forms a double-end support structure for the winding drum, which greatly improves the coaxiality of the drum rotation.

[0010] Optionally, the first groove is located on the outer surface of the winding drum, and there are multiple grooves distributed in a ring around the winding drum. The inner wall of the first groove is slidably connected to the second slider, and the top of the second slider is fixedly connected to the protrusion.

[0011] The above technical solution enables the winding roller to adapt to coil frames with different inner diameters. Positioning is achieved by the protrusions fitting against the inner wall of the frame. This eliminates the need to replace the roller and meets the winding requirements of multiple frame specifications, thus improving the versatility of the device.

[0012] Optionally, the first spring is located between the bottom of the second slider and the inner wall of the bottom of the first groove, and the number of the first springs is multiple and they are evenly distributed along the axial direction of the bottom of the first groove.

[0013] The above technical solution works as follows: when the skeleton is fitted into the roller, the spring compression generates a reaction force that pushes the protrusion to hold the skeleton tightly, which not only prevents the skeleton from loosening, but also prevents damage to the skeleton caused by rigid clamping.

[0014] Optionally, the first slider is located on the outer surface of the threaded rod and is threadedly connected to the threaded rod. The inner wall of the first slider near the center is slidably connected to the first guide rod. There are two first guide rods, which are symmetrically distributed on both sides of the threaded rod. The left side of the first guide rod is fixedly connected to the first mounting bracket.

[0015] The above technical solution converts the rotational motion of the first drive motor into the axial linear motion of the first slider, ensuring that the slider drives the guide wheel to move stably.

[0016] Optionally, the mounting groove is located on the outer surface of the first slider, the second slide groove is located on the inner wall of the left and right sides of the mounting groove, the inner wall of the second slide groove is slidably connected to the third slider, the number of the third sliders is two and they correspond one-to-one with the second slide grooves, and the fixed shaft is located between the two third sliders.

[0017] The above technical solution enables the guide wheel to adjust its position according to changes in conductor tension or skeleton contour, avoiding conductor pulling or loosening caused by rigid installation, and providing structural support for subsequent tension buffering.

[0018] Optionally, the second guide rod is located inside the second slide groove, and its top and bottom are fixedly connected to the top inner wall and bottom inner wall of the second slide groove, respectively. The outer surface of the second guide rod is slidably connected to the third slider. The second spring is sleeved on the outside of the second guide rod and is located between the top of the third slider and the top inner wall of the second slide groove.

[0019] The above technical solution aims to limit the sliding direction of the third slider by using a guide rod, and in conjunction with the elastic extension and contraction of the spring, to achieve real-time buffering of tension fluctuations by the guide wheel.

[0020] In summary, this utility model has at least one of the following beneficial effects: 1. Adaptive wiring and uniform winding: The first drive motor drives the threaded rod and the first slider to move axially. With the precise guidance of the double first guide rods, the wires are arranged tightly without overlapping wires, which meets the electrical performance requirements of high-precision solenoid valves. The guide wheel is elastically adjusted by the second spring and the third slider to keep in real time in contact with the wire and the skeleton surface. Even if there is a slight eccentricity or diameter change in the skeleton, it can still ensure that the wire winding trajectory is consistent with the skeleton outline, avoiding the loosening of the coil caused by suspended winding.

[0021] 2. Rapid changeover and mass production The protrusions on the winding roller adaptively grip the skeleton with different inner diameters through the first spring, eliminating the need to replace the roller or clamps. This shortens the changeover time compared to traditional equipment, making it suitable for multi-variety, small-batch production scenarios and increasing production capacity. The dual drive motors are linked with the control system, reducing manual debugging costs. Attached Figure Description

The output end of the second drive motor 11 extends to the right side of the second mounting bracket 10 and is fixedly connected to an insertion block 18.

[0027] The winding mechanism includes a winding roller 13, a protrusion 14, a connecting rod 9, a limiting plate 12, a first sliding groove 15, a second slider 16, and a first spring 17.

[0028] The left side of the winding roller 13 is inserted into the insert block 18, and the right side of the insert block 18 is threaded into the connecting rod 9. The right end of the connecting rod 9 passes through the winding roller 13 and is fixedly connected to the limiting plate 12. The outer surface of the connecting rod 9 near the right end is rotatably connected to the groove at the top of the right support rod 2. The left side of the limiting plate 12 is tightly fitted to the right side of the right support rod 2. The first slide groove 15 is located on the outer surface of the winding roller 13. There are multiple first slide grooves that are distributed in a ring around the winding roller 13. The inner wall of the first slide groove 15 is slidably connected to the second slider 16. The top of the second slider 16 is fixedly connected to the protrusion 14. The first spring 17 is located between the bottom of the second slider 16 and the bottom inner wall of the first slide groove 15. There are multiple first springs 17 that are evenly distributed along the axial direction of the bottom of the first slide groove 15.

[0029] The dynamic adaptation mechanism for winding position includes a first slider 8, a guide wheel 3, a second slide groove 19, a second guide rod 20, a second spring 21, a third slider 22, a fixed shaft 23, and a mounting groove 24.

[0030] The first slider 8 is located on the outer surface of the threaded rod 6 and is threadedly connected to the threaded rod 6. The inner wall of the first slider 8 near the center is slidably connected to the first guide rod 7. There are two first guide rods 7, which are symmetrically distributed on both sides of the threaded rod 6. The left side of the first guide rod 7 is fixedly connected to the first mounting bracket 4. The mounting groove 24 is located on the outer surface of the first slider 8. The second slide groove 19 is located on the inner wall of the left and right sides of the mounting groove 24. The inner wall of the second slide groove 19 is slidably connected to the third slider 22. There are two third sliders 22, which correspond one-to-one with the second slide groove 19. The fixed shaft 23 is located between the two third sliders 22. The second guide rod 20 is located inside the second slide groove 19, and its top and bottom are fixedly connected to the top inner wall and bottom inner wall of the second slide groove 19, respectively. The outer surface of the second guide rod 20 is slidably connected to the third slider 22. The second spring 21 is sleeved on the outside of the second guide rod 20. The second spring 21 is located between the top of the third slider 22 and the top inner wall of the second slide groove 19.

[0031] Working principle: In the preparation stage, the solenoid valve coil skeleton to be wound is first put into the outer surface of the winding roller 13. When the skeleton is put in, the protrusion 14 is squeezed to make the second slider 16 slide down the first slide groove 15 and compress the first spring 17. The elastic reaction force of the first spring 17 pushes the protrusion 14 to stick tightly to the inner wall of the skeleton, realizing the adaptive clamping of skeletons with different inner diameters. At the same time, the left side of the winding roller 13 is connected to the plug 18 at the output end of the second drive motor 11 to transmit rotational power, and the right side is connected to the top groove of the right support rod 2 through the connecting rod 9. The limiting plate 12 is tightly fitted with the right support rod 2 to restrict axial movement. Then, one end of the enameled wire is fixed to the starting end of the skeleton and the middle section passes around the guide wheel 3 to complete the path construction.

[0032] During the winding stage, the second drive motor 11 is started, which drives the winding roller 13 to rotate synchronously with the skeleton through the insert block 18. At the same time, the first drive motor 5 is started to drive the threaded rod 6 to rotate. Because the first slider 8 and the double first guide rods 7 are slidably connected to restrict the rotation, the rotational motion of the threaded rod 6 is converted into axial linear motion, which drives the guide wheel 3 to move synchronously. The moving speed matches the roller speed to achieve uniform transverse wire laying. When the tension of the wire changes suddenly during winding, the tension increases and the wire presses the guide wheel 3. The fixed shaft 23 pushes the third slider 22 to slide up along the second slide groove 19 to compress the second spring 21. The elastic force offsets part of the tension to prevent the wire from being stretched and broken. When the tension decreases, the second spring 21 releases potential energy to push the third slider 22 down so that the guide wheel 3 is close to the wire to prevent loosening. The second guide rod 20 ensures that the guide wheel 3 only moves radially.

[0033] During the shutdown phase, when the number of turns reaches the target, the control system synchronously stops the two drive motors, loosens the threaded connection between the connecting rod 9 and the insert block 18, pulls the limit plate 12 to disengage the connecting rod 9 from the winding roller 13, removes the coil skeleton that has been wound, and the first drive motor 5 reverses to drive the first slider 8 back to the initial position to prepare for the next cycle. The entire process ensures the winding quality through adaptive positioning, precise wire arrangement, and tension buffering.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
