Technical Field
[0001] This utility model relates to the field of electrode sheet composite processing, specifically an electrode sheet composite device. Background Technology
[0002] The electrode sheet includes a current collector and an electrode film disposed on the current collector. In the preparation of the electrode sheet, the electrode film is usually prepared separately by dry process, and then the electrode film and the current collector are combined together by a composite device to form the electrode sheet.
[0003] In the prior art, such as in the publication number CN221529980U, an electrode sheet composite device is disclosed, which includes: a composite mechanism; a conveying mechanism disposed upstream of the composite mechanism for conveying an electrode film and a current collector to the composite mechanism respectively; and a correction mechanism disposed between the conveying mechanism and the composite roller group for correcting the position of at least one of the electrode film and the current collector relative to the composite mechanism.
[0004] While the aforementioned patent improves the alignment accuracy of the electrode film and current collector and enhances the production quality of the electrode sheet by setting up a correction mechanism to correct the deviation of the electrode film and / or current collector, thereby adjusting the position of the electrode film relative to the current collector, the lack of buffering in the composite mechanism during electrode sheet composite processing, coupled with the thin electrode film, leads to damage during extrusion composite, affecting composite efficiency. Furthermore, air bubbles are generated in the composite gap during electrode film and current collector composite processing, resulting in low composite quality. Therefore, an electrode sheet composite device is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.
[0022] Please see Figures 1-4 As shown, an electrode composite device includes a processing table 1; support rods 2 are fixedly connected to the four corners of the top of the processing table 1; a threaded screw 4 is rotatably connected between two support rods 2 on one side of the top of the processing table 1; one end of the threaded screw 4 is fixedly connected to the output end of a motor 3; the motor 3 is located on the top of a support block 26; the support block 26 is located on the edge of the surface of the processing table 1; a limit rod 6 is provided between two support rods 2 on the other side of the top of the processing table 1; a movable frame 5 is provided on the surface of the threaded screw 4; the interior of one end of the movable frame 5 is slidably connected to the limit rod 6; an electro-hydraulic rod 7 is fixedly connected to the bottom of the movable frame 5; a push rod 8 is fixedly connected to the bottom end of the electro-hydraulic rod 7; both ends of the push rod 8 are slidably connected to the bottom sides of the movable frame 5; an inverted U-shaped frame 9 is fixedly connected to the bottom of the push rod 8; the interior of both ends of the inverted U-shaped frame 9 is slidably connected to the limit rod 6; a limit rod 6 is provided between two support rods 26 on the other side of the top of the processing table 1 ... A U-shaped frame 10 is slidably connected to the front U-shaped frame 10. Fixed holes are opened at the top of both ends of the U-shaped frame 10. A spring A 11 is installed inside the fixed holes. A limit post 12 is installed at one end of the spring A 11. Several limit holes 13 that are adapted to the limit posts 12 are opened from top to bottom on both sides of the inverted U-shaped frame 9. A sliding hole is opened on the bottom surface of the front U-shaped frame 10. A slide rod 14 is slidably connected inside the sliding hole. A spring B 15 is sleeved on the slide rod 14. The spring B 15 is set at the bottom of the front U-shaped frame 10 and is coaxial with the sliding hole. A connecting frame 16 is fixedly connected to the bottom of the slide rod 14. A roller 17 is movably connected to the bottom of the connecting frame 16. Several fixing rings 18 are sleeved on the surface of the roller 17. Several micro airbags 19 are set on the surface of the fixing rings 18. A base plate 24 is set on the top of the processing table 1. A placement groove 25 is opened on the surface of the base plate 24.
[0023] During operation, the electrode sheet is placed in the placement slot 25 of the base plate 24; the motor 3 is started to drive the threaded screw 4 to rotate, so that the moving frame 5 moves horizontally along the limiting rod 6 to above the electrode sheet; the electric hydraulic rod 7 pushes the push rod 8 down to make the roller 17 contact the electrode sheet; during the rolling process, the slide rod 14 is pressured and moves down along the sliding hole of the positive U-shaped frame 10 to compress the B spring 15, forming an elastic buffer; at the same time, the micro air bladder 19 on the surface of the roller 17 contacts the surface of the electrode sheet and rolls to de-foam. Through the elastic buffer of the slide rod 14 / B spring 15 and the sliding connection of the push rod 8, a three-level anti-damage structure is formed, which significantly reduces the electrode film damage rate.
[0024] Furthermore, an air pump 20 is installed inside one end of the roller 17, and a solenoid valve 21 is installed at the output end of the air pump 20. The solenoid valve 21 is electrically connected to the control module 22 through a wire. Several air pipes 23 are installed at the output end of the solenoid valve 21, and one end of the air pipe 23 is connected to the fixed ring 18.
[0025] During operation, the air pump 20 supplies air to the solenoid valve 21, and the control module 22 opens and closes the solenoid valve 21 at a preset frequency, so that the compressed air enters the micro air bladder 19 of the fixed ring 18 through the air pipe 23 and periodically expands and contracts. Based on the high-frequency pulsation of the micro air bladder 19 and the precise control of the solenoid valve 21, the efficiency of bubble removal is multiplied.
[0026] Furthermore, the limiting post 12 is slidably disposed inside the fixing hole, one end of spring A 11 abuts against the inner wall of the fixing hole, and the other end abuts against the limiting post 12, and the limiting post 12 is inserted into the limiting hole 13.
[0027] During operation, pressing the limiting post 12 compresses the A spring 11, causing it to disengage from the limiting hole 13. After adjusting the relative height of the positive U-shaped frame 10 within the negative U-shaped frame 9, the A spring 11 resets and pushes the limiting post 12 into the corresponding limiting hole 13 for fixation. Through the insertion and removal mechanism of the limiting post 12 / limiting hole 13 and the elastic reset of the A spring 11, tool-free differential pressure adjustment is achieved.
[0028] Furthermore, the slide bar 14 passes through the sliding hole and extends to the bottom of the U-shaped frame 10, and one end of the spring 15 abuts against the bottom surface of the U-shaped frame 10, while the other end abuts against the top of the connecting frame 16.
[0029] During operation, when the rolling pressure is transmitted to the slide bar 14, the B spring 15 is compressed and deformed between the bottom surface of the U-shaped frame 10 and the top of the connecting frame 16. After the pressure is released, the B spring 15 pushes the slide bar 14 to reset. By utilizing the linear contact structure between the slide bar 14 and the B spring 15, the uniformity of the membrane stress is significantly improved.
[0030] Furthermore, a placement groove 25 is formed on the surface of the base plate 24, and the shape of the placement groove 25 is adapted to the outline of the electrode sheet.
[0031] During operation, the electrode sheet is embedded in the placement groove 25 opened on the surface of the base plate 24. The groove outline tightly wraps around the four sides of the electrode sheet. The electrode sheet is positioned by conforming to the placement groove 25 of the base plate 24, and the composite misalignment rate approaches zero.
[0032] Furthermore, the fixing rings 18 are equidistantly distributed along the axial direction of the roller 17, and the micro airbags 19 are distributed in a ring array on the surface of the fixing rings 18.
[0033] During operation, the fixing rings 18 are arranged at equal intervals along the axial direction of the roller 17, and the micro air bladders 19 on the surface of each fixing ring 18 are evenly distributed in a circle. Based on the axially equidistant layout of the fixing rings 18 and the annular array distribution of the micro air bladders 19, the edge bonding strength is greatly enhanced.
[0034] Working principle: After the electrode sheet is positioned in the placement groove 25 of the base plate 24, the motor 3 is started to drive the threaded screw 4 to rotate, which drives the moving frame 5 to move horizontally above the electrode sheet along the limiting rod 6; the electric hydraulic rod 7 pushes the push rod 8 down to make the inverted U-shaped frame 9 descend. The height of the positive U-shaped frame 10 is set by adjusting the insertion position of the limiting post 12 and the limiting hole 13. When the roller 17 contacts the electrode sheet, the slide rod 14 moves down along the sliding hole of the positive U-shaped frame 10 to compress the B spring 15 to form an elastic buffer; at the same time, the air pump 20 periodically supplies air to the micro air bladder 19 of the fixed ring 18 through the solenoid valve 21 and the air pipe 23. As the roller 17 rolls, the micro air bladder 19 expands and contracts to generate vibration and remove air bubbles, thus completing the composite processing.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
