[0002] Sodium-ion batteries are a type of rechargeable battery that primarily functions by the movement of sodium ions between the positive and negative electrodes, similar to the working principle of lithium-ion batteries. The production process of sodium-ion batteries involves pressing the positive and negative electrode sheets. However, after pressing, the sheets are difficult to remove from the pressing chamber, reducing work efficiency.

[0003] A pressing device for positive and negative electrode sheets used in the production of sodium-ion batteries, with application number CN202222164114.2, although it pushes a sliding rod upward so that the sliding rod slides upward along the inner surface of the sliding groove, and further drives the connecting rod and the top plate to slide upward, and finally the top plate lifts the battery sheet to achieve rapid demolding and greatly improve work efficiency, still requires the top plate to remove the battery sheet from the top plate after pushing the battery sheet upward out of the pressing groove. This makes the battery pressing production steps cumbersome, resulting in low battery pressing production efficiency. Utility Model Content

[0023] Reference Figures 1 to 6This utility model provides a pressing device for positive and negative electrodes of a solid sodium battery: It includes an operating table 1, with a frame 6 movably connected to the top surface of the operating table 1.

One end of the screw 9 is rotatably connected to a support plate 5, which is fixed to the top surface of the operating table 1. The other end is drive-connected to a drive motor 8, which is horizontally fixed to the top surface of the operating table 1. A pressing component is vertically connected to the bottom surface of the frame 6. Multiple pressing grooves 3, adapted to the pressing component, are vertically formed on the top surface of the operating table 1. A top plate 4 is telescopically connected to each pressing groove 3. The operating table 1 has an empty space... Cavity 20, with telescopic connection to base plate 19 inside cavity 20. Multiple guide rods 18 are vertically fixed to the top surface of base plate 19. Each guide rod 18 is movably connected to each pressure groove 3. Each electric guide rod 18 has a top plate 4 fixed to its top surface. Two mirror-symmetrical sliding grooves 22 are vertically opened on the inner wall of cavity 20. Each sliding groove 22 is slidably connected to a slider 23. The slider 23 is fixedly connected to base plate 19. A spring 24 is fixed between sliding groove 22 and slider 23. Multiple guide grooves 11 adapted to pressure groove 3 are opened on the rear side of operating table 1. Each guide groove 11 is movably connected to a conveyor belt 10. A downwardly inclined guide groove 2 is opened on the front side of operating table 1.

[0024] The tablet pressing component includes a lifting plate 14 that is lifted and connected below the frame 6. Two mirror-symmetrical electric push rods 13 are vertically fixed to the bottom surface of the frame 6. The ends of the two electric push rods 13 are jointly fixed to a lifting plate 14. A hollow block 15 is provided above each pressing groove 3. The hollow block 15 is fixed to the bottom surface of the lifting plate 14. Multiple equidistant air holes 25 are vertically opened on the bottom surface of each hollow block 15. A gas pipe 16 is vertically connected to the top surface of each hollow block 15. The gas pipe 16 passes through the lifting plate 14. Multiple equidistant air pumps 12 are vertically fixed to the top surface of the lifting plate 14. The end of each air pump 12 is connected to a gas pipe 16.

[0025] Multiple guide grooves 11 are connected to multiple equidistant conveyor rollers 21 that rotate together. Each conveyor belt 10 is sleeved on the outer edge of the multiple conveyor rollers 21. A conveyor motor 7 is horizontally fixed on the side of the operating table 1. The output end of the conveyor motor 7 is connected to the end of one of the conveyor rollers 21. Each conveyor roller 21 has three pairs of equidistant axially distributed annular grooves 27 concentrically opened on its outer edge. The outer edges of multiple annular grooves 27 on the same radial line are connected to a limiting ring 26. Each conveyor belt 10 has two axially symmetrical limiting rings 26 fixedly connected to its inner side.

[0026] By opening a pressing groove 3 on the top surface of the operating table 1, and telescopically connecting a top plate 4 in each pressing groove 3, and movably connecting a hollow block 15 on the top surface of the operating table 1, it is convenient to unload the battery positive and negative electrode sheets after pressing without manual unloading. A guide groove 11 is opened on the rear side of the operating table 1, and a conveyor belt 10 is set in the guide groove 11 to facilitate automatic feeding of positive and negative electrode sheets, thereby improving the pressing production efficiency of positive and negative electrode sheets.

[0027] Working principle: In use, the positive and negative electrode sheets are placed on the conveyor belt 10, which transports them to the direction of the pressing groove 3. Then, the drive motor 8 and screw 9 drive the frame 6 to move towards the conveyor belt 10, so that the pressing block moves to directly above the positive and negative electrode sheets on the conveyor belt 10, and then stops. Next, the electric push rod 13 pushes the lifting plate 14 to descend, and the support plate 5 drives the pressing block to descend, so that the pressing block adheres to the electrode sheets on the conveyor belt 10. Then, the air pump 12 starts, adsorbing and fixing the electrode sheets to the bottom surface of the pressing block. Then, the pressing block rises, so that the electrode sheets adhere to the bottom surface of the pressing block. The bottom surface of the electrode is flush with the top surface of the operating table 1. The frame 6 moves the electrode with the bottom surface of the hollow block 15 to the top surface of the pressing groove 3. Then, the hollow block 15, carrying the electrode, descends into the pressing groove 3, so that the electrode is pressed in the pressing groove 3. At the same time, the top plate 4 descends, and the top plate 4 drives the bottom plate 19 to descend through the guide rod 18. At the same time, the spring 24 is compressed. After the pressing is completed, the air pump 12 is turned off, the hollow block 15 rises, and as the hollow block 15 rises, the spring 24 returns to its original position. At the same time, the bottom plate 19 and the top plate 4 rise until the hollow block 15 is removed from the pressing groove 3. The electrode is moved outwards, and at this point, the bottom surface of the pressed electrode is flush with the top surface of the operating table 1. Then, the frame 6 moves towards the conveyor belt 10, taking out the second electrode from the conveyor belt 10. After receiving it, the hollow block 15 rises, and the second electrode is flush with the top surface of the operating table 1. Then, it drives the second electrode to move towards the pressing groove 3. When the second electrode moves towards the pressing groove 3, it pushes the pressed electrode off the top plate 4, causing it to move into the guide chute 2. The pressed electrode is then placed in the guide chute 2 at an angle. Under the action of the surface, the second electrode sheet is automatically unloaded from the operating table 1. At the same time, the second electrode sheet will move to the top plate 4. Then the hollow block 15 descends into the pressing groove 3 to press the second electrode sheet. After pressing, the third electrode sheet is pressed. When the third electrode sheet is being fed, the pressed electrode sheet on the top plate 4 is pushed out. This operation is repeated to realize the automatic loading and unloading function of positive and negative electrode sheets during pressing. There is no need to manually remove the electrode sheet from the top plate 4, thereby improving the efficiency of pressing positive and negative electrode sheets of sodium battery.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
