Description

Technical Field

[0001] This utility model relates to the technical field of capacitor production equipment, specifically to a capacitor multi-tab parallel winding equipment. Background Technology

[0002] Capacitor core winding is one of the key processes in capacitor manufacturing. It involves winding capacitor films, aluminum foils, or electrodes together in a designed combination to form the capacitor core.

[0003] The existing publicly available technology, application number CN202221398780.6, discloses a lithium-ion electrode winding mechanism. By staggering the positive electrode unwinding assembly and the negative electrode unwinding assembly around the winding needle assembly, it can ensure that the multi-tab positive electrode strip and the multi-tab negative electrode strip can smoothly enter the winding needle assembly. This facilitates obtaining the angle at which the multi-tab positive electrode strip and the multi-tab negative electrode strip enter the winding needle, improving the winding efficiency and thus improving the winding efficiency and quality of lithium-ion batteries.

[0004] Based on the aforementioned patents and existing winding machines, it is not difficult to find that during use, due to the thinness of the electrode sheets and the thin and long tabs on them, the winding speed is relatively fast. When the electrode sheets pass through the cylindrical rollers of the winding machine, the tabs are prone to folding, or even tearing at the root of the tabs and breaking the tape. This affects the subsequent winding quality, leading to a decline in product quality and thus affecting the performance of the capacitor. Furthermore, the limited winding structure results in a relatively limited range of applicable electrode thicknesses, making it impossible to wind different types of electrode sheets and reducing the overall performance.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a capacitor multi-tab parallel winding device, which has the advantages of good tab smoothing effect, wide applicability, and high winding quality, thereby solving the problems mentioned in the background technology.

[0007] To achieve the advantages of good tab smoothing effect, wide applicability, and high winding quality, the specific technical solution adopted by this utility model is as follows: A capacitor multi-tab parallel winding device includes a worktable and a winding plate. A first lead screw is installed inside one side of the top of the worktable, with one end of the first lead screw passing through one side of the worktable and connected to a first motor. A lower bracket is sleeved around the outer periphery of the first lead screw, and the lower bracket is slidably connected to the worktable. A fixed seat is symmetrically installed on one side of the lower bracket at the top of the worktable. An adjusting seat is slidably connected to the top of the fixed seat. A hydraulic rod is installed between the fixed seat and the adjusting seat. A second lead screw is installed inside the top of the adjusting seat, with one end of the second lead screw passing through one side of the adjusting seat and connected to a second motor. The second lead screw is sleeved with an upper bracket, which is slidably connected to the surface of the adjusting seat. The upper and lower brackets are rotatably connected to the surfaces of the upper and lower brackets, respectively. A fixed frame is mounted on one side of the fixed seat at the middle of the top of the workbench. A third lead screw and a sliding rod are installed on both sides inside the fixed frame. A moving head is sleeved between the third lead screw and the sliding rod. One end of the third lead screw passes through one side of the fixed seat and is connected to a fourth motor. A moving frame is welded to one end of the moving head. A leveling roller is rotatably connected to the bottom of the moving frame. One end of the leveling roller is connected to the output end of the third motor.

[0008] Furthermore, a work plate is installed on the other side of the top of the workbench. A fixed plate is fixedly installed on the surface of the work plate. A rotating disk is rotatably connected to the surface of the fixed plate. An adjustment groove is opened on the surface of the rotating disk. A bidirectional lead screw is installed inside the adjustment groove. A winding plate is symmetrically sleeved at both ends of the bidirectional lead screw. One end of the bidirectional lead screw passes through one side of the adjustment groove and is connected to the fifth motor.

[0009] Furthermore, support legs are symmetrically installed on both sides of the bottom of the workbench.

[0010] Furthermore, several sets of bearing plates are provided between the fixed base and the working plate at the top of the worktable.

[0011] Furthermore, one end of the rotating disk passes through one side of the working plate and is connected to the motor.

[0012] Furthermore, a guide groove is provided at the top of the workbench for the lower support to move.

[0013] Furthermore, a controller is provided on one side of the workbench.

[0014] Furthermore, the surfaces of the upper smoothing roller, lower smoothing roller, leveling roller, and winding plate are all provided with a rubber layer.

[0015] Compared with the prior art, the present invention provides a capacitor multi-tab parallel winding device, which has the following beneficial effects: (1) This utility model adopts a flattening roller, an upper flattening roller, and a lower flattening roller. After all adjustments are completed, the electrode sheet can be placed on the support plate and moved along the support plate to the working plate. When the electrode sheet moves between the upper flattening roller and the lower flattening roller, the operation of the first motor and the second motor can drive the two sets of rollers to move laterally. If the electrode tab on the electrode sheet is not bent, it can roll over smoothly. If the electrode tab is bent, the electrode tab can be flattened again by relative squeezing when the roller moves, ensuring the flatness of subsequent winding. Then the electrode sheet can be moved to the bottom of the flattening roller for secondary flattening to avoid bending. The device uses multiple flattening structures in combination to effectively flatten and smooth the bent electrode tab, reducing the probability of bent products. It has the advantages of good electrode tab flattening effect and high winding quality.

[0016] (2) This utility model adopts a hydraulic rod, a fourth motor, and a fifth motor. Before the winding operation, the hydraulic rod, the fourth motor, and the fifth motor can be driven separately according to the different sizes of the capacitor plates connected in parallel with the multi-pole ears to be wound. The operation of the hydraulic rod can drive the adjusting seat to move up and down accordingly, thereby changing the distance between the upper and lower smoothing rollers. Then, the operation of the fourth motor can drive the third lead screw to rotate, thereby driving the moving head to move up and down along the fixed frame, so that the distance between the smoothing roller and the bearing plate changes. Finally, the operation of the fifth motor can drive the bidirectional lead screw to rotate, thereby changing the distance between the winding plates. Through the adjustment of multiple sets of structures, the device can better adapt to the winding operation of plates of different sizes, expand the application range of the device, improve the practicality of the structure, and has the advantage of wide applicability.

[0023] In one embodiment, a work plate 26 is installed on the other side of the top of the workbench 1. A fixed plate 24 is fixedly installed on the surface of the work plate 26. A rotating plate 23 is rotatably connected to the surface of the fixed plate 24. An adjustment groove 21 is opened on the surface of the rotating plate 23. A bidirectional lead screw 25 is installed inside the adjustment groove 21. A winding plate 28 is symmetrically sleeved at both ends of the bidirectional lead screw 25. One end of the bidirectional lead screw 25 passes through one side of the adjustment groove 21 and is connected to a fifth motor 22. The winding plate 28 is set to achieve the winding operation by clamping and rotating the capacitor electrode. An auxiliary roller can be set between the winding plate 28 and the support plate 2 to achieve the upward guidance operation of the electrode, which facilitates better uniform winding operation.

[0024] In one embodiment, support legs 27 are symmetrically installed on both sides of the bottom of the workbench 1. The support legs 27 can fix the entire device, which helps to ensure the stability of the operation.

[0025] In one embodiment, a number of bearing plates 2 are provided at the top of the worktable 1 between the fixed base 16 and the work plate 26. The bearing plates 2 are provided to support and transport the electrode sheets, which facilitates subsequent smoothing and winding operations.

[0026] In one embodiment, one end of the rotary disk 23 passes through one side of the working plate 26 and is connected to the motor. The connection between the rotary disk 23 and the motor is to realize the winding operation of the capacitor electrode.

[0027] In one embodiment, a guide groove is provided at the top of the workbench 1 for the lower support 6 to move.

[0030] Working Principle: In actual use, the hydraulic rod 15, the fourth motor 18, and the fifth motor 22 can be driven separately according to the different sizes of the capacitor plates connected in parallel with multiple tabs to be wound. The operation of the hydraulic rod 15 can drive the adjusting seat 13 to move up and down accordingly, thereby changing the distance between the upper smoothing roller 11 and the lower smoothing roller 9. Then, the operation of the fourth motor 18 can drive the third lead screw 19 to rotate, thereby driving the moving head 20 to move up and down along the fixed frame 3, changing the distance between the flattening roller 5 and the support plate 2. Finally, the operation of the fifth motor 22 can drive the bidirectional lead screw 25 to rotate, thereby changing the distance between the winding plates 28. Through the adjustment of multiple sets of structures, the device can better adapt to the winding operation of plates of different sizes, expand the applicability of the device, and improve the practicality of the structure. After all adjustments are completed, the plates can be placed on the support plate 2. The electrode moves along the support plate 2 towards the working plate 26. When the electrode moves between the upper smoothing roller 11 and the lower smoothing roller 9, the first motor 8 and the second motor 12 can drive the two sets of rollers to move laterally. If the electrode tabs on the electrode are not bent, they can roll smoothly. If the electrode tabs are bent, they can be smoothed again by relative compression when the rollers move, ensuring the flatness of subsequent winding. Then the electrode can move to the flattening roller 5 for secondary flattening to avoid bending. Finally, the electrode will be inserted between the winding plates 28. The winding operation of the electrode tabs can be realized by the rotation of the winding plates 28. After winding is completed, the wound product can be pushed out directly or manually removed, which is convenient for subsequent electrode winding operations and facilitates the production and processing of capacitors. The device as a whole has the advantages of good electrode tab smoothing effect, wide applicability, and high winding quality.
