DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment:

[0028] Please refer to Figures 1 - 8 , the present invention provides a technical solution:

[0029] A capacitor production winding device includes a base 1. A winding frame 2 is fixedly installed at the rear end of the top of the base 1. A winding motor 3 is fixedly installed at the rear end of the bottom of the base 1. A first quick-release mechanism 4 is fixedly installed on the driving end of the winding motor 3 and inside the winding frame 2. A limiting plate 5 is installed inside the winding frame 2 and above the first quick-release mechanism 4. Two groups of second quick-release mechanisms 6 are installed at the front end of the top of the base 1. A plurality of winding rollers 7 are fixedly connected at the middle of the top of the base 1. A tension rod 8 is installed between the plurality of winding rollers 7.

[0030] First of all, the first quick-release mechanism 4 includes a turntable 401 fixedly connected to the driving end of the winding motor 3. A plurality of movable rings 402 are movably installed above the turntable 401. A plurality of clamping blocks 403 are movably installed between the movable rings 402 and the turntable 401. A fixed rod 404 is fixedly connected to the outside of the turntable 401. An operating handle 405 is fixedly connected to the outside of the movable ring 402. The operating handle 405 is fixedly connected to the fixed rod 404 through a pin 406. During the production of capacitors, first insert the capacitor core rod into the inside of the movable ring 402. Then, rotate the movable ring 402 through the operating handle 405 to drive the plurality of clamping blocks 403 to move synchronously, and fix the outside of the capacitor core rod through the plurality of clamping blocks 403. Then insert the pin 406 into the inside of the fixed rod 404 to fix the movable ring 402, which is convenient for quickly disassembling and assembling the capacitor core rod, thereby improving the production efficiency of capacitors. Drive the turntable 401 to rotate through the winding motor 3, and drive the capacitor core rod to rotate for winding.

[0031] Furthermore, the bottoms of the plurality of clamping blocks 403 are all slidably connected to the turntable 401 through sliding grooves 407, and the tops of the plurality of clamping blocks 403 are all slidably connected to the movable ring 402 through guiding grooves 408. When the movable ring 402 rotates, under the connection of the sliding grooves 407 and the guiding grooves 408, drive the plurality of clamping blocks 403 to rotate synchronously to fix the outside of the capacitor core rod.

[0032] Then, a telescopic rod 501 is fixedly connected to the center of the top of the limit plate 5. A sleeve 502 is sleeved outside the telescopic rod 501. A spring 503 is movably installed inside the sleeve 502. The top of the sleeve 502 is rotatably connected to the winding frame 2 through a bearing. After the capacitor mandrel is fixed, the telescopic rod 501 is pushed downward under the action of the spring 503. During winding, the top of the capacitor mandrel is limited by the limit plate 5, so as to avoid the winding layer from deviating and ensure the production quality of the capacitor.

[0033] Secondly, the second quick-release mechanism 6 includes a rotating rod 601 rotatably connected to the front end of the top of the base 1. The bottom end of the rotating rod 601 is rotatably connected to a first connecting sleeve 602. A second connecting sleeve 603 is rotatably connected to the outside of the rotating rod 601 and above the first connecting sleeve 602. The top end of the rotating rod 601 is threadedly connected to an adjusting sleeve 604. A plurality of fixing plates 605 are installed on the outside of the rotating rod 601. The inner sides of the plurality of fixing plates 605 are all rotatably connected to the first connecting sleeve 602, the second connecting sleeve 603, and the adjusting sleeve 604 through a transmission frame 606. The outside of the adjusting sleeve 604 is fixedly connected to a rotating handle 607. The plurality of fixing plates 605 are equally spaced on the outside of the rotating rod 601. During capacitor production, the aluminum foil roller and the film roller are respectively sleeved on the outside of the two rotating rods 601. Then, the adjusting sleeve 604 is rotated through the rotating handle 607. As the adjusting sleeve 604 moves downward, under the transmission of the plurality of transmission frames 606, the plurality of fixing plates 605 are driven to expand outward, so as to facilitate the quick fixing of the inner sides of the aluminum foil roller and the film roller. When the aluminum foil roller and the film roller need to be disassembled and replaced, only need to rotate the adjusting sleeve 604 upward to drive the plurality of fixing plates 605 to contract, releasing the fixing of the inner sides of the aluminum foil roller and the film roller, thus greatly improving the disassembly and assembly convenience of the aluminum foil roller and the film roller, and further improving the production efficiency of the capacitor.

[0034] Finally, a limit sleeve 701 is threadedly connected to the top ends of the plurality of winding rollers 7. An adjusting block 801 is fixedly connected to the bottom end of the tension rod 8. A threaded rod 802 is rotatably connected inside the base 1, and the threaded rod 802 is threadedly connected to the adjusting block 801. A crank 803 is fixedly connected to the left end of the threaded rod 802. The aluminum foil and the film led out from the aluminum foil roller and the film roller pass around and overlap through the winding roller 7, and then are led to the outside of the capacitor mandrel for winding. At the same time, before the winding operation, the limit sleeve 701 is rotated downward to limit the top of the aluminum foil and the film, further preventing the winding layer from deviating. During the winding process, the threaded rod 802 can be rotated through the crank 803, and under the connection of the adjusting block 801, the tension rod 8 is driven to move leftward, so as to adjust the tension of the aluminum foil and the film and ensure that the aluminum foil and the film are in a taut state during winding, further ensuring the production quality of the capacitor.

[0035] In this embodiment, the implementation scenario is specifically as follows: during the production of capacitors, first insert the capacitor mandrel into the inner side of the movable ring 402, and then rotate the movable ring 402 through the operating handle 405 to drive the synchronous movement of multiple groups of clamping blocks 403, and fix the outer side of the capacitor mandrel through multiple groups of clamping blocks 403. Subsequently, insert the pin 406 into the inner side of the fixed rod 404 to fix the movable ring 402, which facilitates the quick disassembly and assembly of the capacitor mandrel. Sleeve the aluminum foil roller and the film roller on the outer sides of the two rotating rods 601 respectively, and then rotate the adjusting sleeve 604 through the rotating handle 607. With the downward movement of the adjusting sleeve 604, under the transmission of multiple groups of transmission frames 606, drive the outward support of multiple groups of fixing plates 605, thereby facilitating the quick fixation of the inner sides of the aluminum foil roller and the film roller. When it is necessary to disassemble and replace the aluminum foil roller and the film roller, only need to rotate the adjusting sleeve 604 upward to drive the contraction of multiple groups of fixing plates 605 and release the fixation of the inner sides of the aluminum foil roller and the film roller. The aluminum foil and the film derived from the aluminum foil roller and the film roller pass through the winding roller 7 and overlap, and then are introduced to the outer side of the capacitor mandrel for winding. At the same time, before the winding operation, rotate the limiting sleeve 701 downward to limit the top of the aluminum foil and the film, further preventing the winding layer from deviating. During the winding process, the tension rod 8 can be driven to move leftward by rotating the threaded rod 802 through the crank 803. Under the connection of the adjusting block 801, the tension of the aluminum foil and the film can be adjusted to ensure that the aluminum foil and the film are in a taut state during winding. Drive the turntable 401 to rotate through the winding motor 3, and drive the capacitor mandrel to rotate for winding. The entire operation process is simple and convenient. Compared with the existing capacitor production and winding device, the present utility model is designed to facilitate the quick disassembly and assembly of the capacitor mandrel, the aluminum foil roller and the film roller, improves the production efficiency of capacitors, and at the same time can prevent the winding layer from deviating and ensure the production quality of capacitors.
