In addition, existing winding devices cannot wind aluminum electrolytic capacitors of different specifications and lengths, often requiring the replacement of corresponding winding limiting devices, which is cumbersome, reduces production efficiency, and increases production costs. Therefore, we need to propose a winding device for aluminum electrolytic capacitors. Utility Model Content

[0023] 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.

[0024] This utility model provides: a winding device for aluminum electrolytic capacitors, such as... Figure 1-4 As shown, the system includes a workbench 1, a movable seat 2, a limiting plate 3, a rotating column 7, and a winding column 18. The winding column 18 is sleeved on the outer arc surface of the rotating column 7 for winding capacitors. Two sets of limiting plates 3 are provided. The two sets of limiting plates 3 have material picking grooves 6 on their sides to ensure that the limiting plates 3 are far away from the rotating column 7. The size of the material picking grooves 6 is larger than the size of the rotating column 7 plus the limiting block 19, so that the rotating column 7 and the limiting block 19 will not contact the limiting plates 3 when rotating. At the same time, it ensures that after winding is completed, the two sets of limiting plates 3 can move away from the winding column 18 through the material picking grooves 6, thereby ensuring the convenience of loading and unloading materials.

[0025] Preferably, the winding column 18 is located between two sets of limiting plates 3 to limit the winding material. A pressing assembly for pressing the material on the surface of the winding column 18 is provided between the two sets of limiting plates 3. The pressing assembly includes a telescopic sleeve plate 5, an anti-detachment block 22, and a telescopic inner plate 25. The telescopic inner plate 25 is slidably disposed inside the telescopic sleeve plate 5. An anti-detachment groove 26 is provided on the upper surface of the telescopic sleeve plate 5 to limit the anti-detachment block 22. The telescopic sleeve plate 5 and the telescopic inner plate 25 are in contact with the two sets of extension plates 4 respectively. The telescopic inner plate 25 is slidably disposed inside the telescopic sleeve plate 5, thereby ensuring that when the distance between the two sets of limiting plates 3 changes, the telescopic sleeve plate 5 and the telescopic inner plate 25 can move accordingly. The anti-detachment block 22 is provided to move along the anti-detachment groove 26 to ensure that the telescopic inner plate 25 can slide inside the telescopic sleeve plate 5 while preventing the entire telescopic inner plate 25 from detaching from the telescopic sleeve plate 5.

[0026] It is worth noting that the pressing assembly also includes lifting blocks 23. The upper surfaces of both sets of limiting plates 3 are provided with extension plates 4 to allow movement of the telescopic sleeve plate 5 and the telescopic inner plate 25. Lifting blocks 23 are provided on opposite sides of the telescopic sleeve plate 5 and the telescopic inner plate 25. Lifting grooves 17 for limiting the lifting blocks 23 are provided on the corresponding surfaces of both sets of extension plates 4. Compression springs 24 for providing pressure to the telescopic sleeve plate 5 and the telescopic inner plate 25 are provided on the upper surfaces of both sets of lifting blocks 23. The lifting blocks 23 are protrusions that engage with the lifting grooves. The internal movement of the 17th section ensures that the telescopic sleeve 5 and the telescopic inner plate 25 can move along with the movement of the two sets of limiting plates 3. The two sets of compression springs 24 are made of the same material and are of the same size. At the same time, the two sets of lifting blocks 23 are at the same height, ensuring that the two sets of compression springs 24 can provide the same thrust to the telescopic sleeve 5 and the telescopic inner plate 25. This allows the telescopic sleeve 5 and the telescopic inner plate 25 to limit the material on the outer arc surface of the winding column 18, preventing the material from bulging or flying up during winding.

[0027] Furthermore, the movable seat 2 is internally equipped with an adjustment assembly for limiting the distance between the two sets of limiting plates 3 to limit the winding columns 18 of different specifications. The adjustment assembly includes a rotating rod 14 and a locking groove 16. The lower surfaces of the two sets of limiting plates 3 are each provided with a locking block 15 that drives the limiting plates 3 to move. The locking block 15 is locked into the locking groove 16 to limit the limiting plates 3. The outer arc surface of the rotating rod 14 is provided with two sets of external threads for threaded connection with the locking block 15, and the two sets of external threads are set in opposite directions. The locking block 15 is set as a protrusion and runs along the locking groove. The groove 16 moves internally to ensure that the two sets of limiting plates 3 do not tilt or rotate during movement. The two sets of locking blocks 15 are symmetrically sleeved on the outer arc surface of the rotating rod 14. The rotation of the rotating rod 14 drives the two sets of locking blocks 15 to move towards or away from each other through two sets of threads in opposite directions. This allows the distance between the two sets of limiting plates 3 to be adjusted according to the different sizes of capacitors and winding columns 18. This ensures that the two sets of limiting plates 3 limit the material on the outer arc surface of the winding column 18 while making the winding device suitable for capacitors and winding columns 18 of different sizes.

[0028] Furthermore, the movable seat 2 slides on the upper surface of the worktable 1 to facilitate loading and unloading of the winding column 18. The worktable 1 is equipped with a moving assembly for moving the movable seat 2 on the upper surface of the worktable 1. The moving assembly includes a lead screw 12 and an adjusting block 21. The adjusting block 21 is located on the lower surface of the movable seat 2. An adjusting groove 13 is provided on the upper surface of the worktable 1 to limit the adjustment block 21. The adjusting block 21 is threaded onto the outer arc surface of the lead screw 12. One end of the lead screw 12 is provided with another set of turntables 10 to drive the lead screw 12 to rotate. The lead screw 12 drives the adjusting block 21 to move through the thread. The adjusting block 21 is also set as a protrusion and moves along the adjusting groove 13. Thus, the moving seat 2 is moved through the adjusting block 21, which in turn drives the two sets of limiting plates 3 and the pressing assembly away from the winding column 18, which facilitates loading and unloading and also facilitates the replacement of winding columns 18 of different specifications.

[0029] Specifically, the upper surface of the workbench 1 is provided with a support plate 8 to support the rotating column 7. The outer arc surface of the rotating column 7 is symmetrically provided with a limiting block 19 to limit the winding column 18. The side of the support plate 8 is bolted with a motor 9 for driving the rotating column 7 to rotate. The side of the movable seat 2 is provided with a support frame 20 to support the rotating rod 14. The inner side of the support plate 8 is provided with a moving groove 11 to ensure the movement of the rotating rod 14 and the support frame 20. One end of the rotating rod 14 is provided with a turntable 10. The motor 9 is started to drive the rotating column 7 to rotate. The rotating column 7 drives the winding column 18 to rotate stably through the limiting blocks 19 on both sides. The support frame 20 is provided to provide auxiliary support for the rotating rod 14 to ensure the stability of the rotating rod 14 during rotation. At the same time, the moving groove 11 is provided to ensure the smooth movement of the movable seat 2 as a whole.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
