Description

Technical Field

[0001] This utility model relates to the field of sodium battery processing technology, and in particular to a device for surface treatment of hard carbon negative electrode of sodium battery. Background Technology

[0002] The main functions of hard carbon anodes in sodium-ion batteries include improving energy density, range, and cycle stability. Hard carbon anode materials possess abundant nanopores and a disordered crystal arrangement, enabling them to store more sodium ions, thereby increasing the battery's specific capacity and energy density. Furthermore, the more uniform expansion and contraction of hard carbon anodes during discharge enhances cycle stability and charge-discharge performance, extending battery life. However, the production process of hard carbon anodes for sodium-ion batteries requires surface treatment and electrophoresis. This necessitates placing the hard carbon anode material in an electrophoresis cage and then immersing the cage in the electrophoresis solution. This process requires the surface of the hard carbon anode material to be in contact with the cage, which can prevent the material from fully contacting the electrophoresis solution, affecting subsequent processing and ultimately reducing its performance.

[0029] An adjusting support plate 8 is fixedly connected to the top of the mounting recess 5. An adjusting cross plate 9 is fixedly connected between the two adjusting support plates 8. Two push plates 10 are provided through the top of the adjusting cross plate 9. A push-shaped plate 11 is fixedly connected between one end of the two push plates 10. A push block 12 is fixedly connected to the other end of each of the two push plates 10. A push assembly is connected to the top of the adjusting cross plate 9. The push assembly includes a drive support plate 13 fixedly connected to the top of the adjusting cross plate 9. A drive motor 14 is fixedly connected to the surface of the drive support plate 13. The output shaft of the drive motor 14 passes through the drive support plate 13 and is fixedly connected to the drive support plate 15. A drive shaft 16 is rotatably connected to the back of the drive support plate 15. The drive shaft 16 is slidably connected to the inside of the push-shaped plate 11. The drive motor 14 drives the drive support plate 15 to rotate.

[0030] Each of the two push plates 10 has a rotatable shaft 17 symmetrically connected to one side. A movable receiving mesh plate 18 is fixedly connected between one end of the two movable shafts 17. Two movable sleeves 19 are fixedly connected to the front and rear sides of the movable receiving mesh plate 18. A movable support plate 20 is slidably fitted inside the movable sleeve 19. A movable stop is fixedly connected to one end of the movable support plate 20. A movable mesh cover 21 is fixedly connected between the other ends of the four movable support plates 20. Movable bolts are threaded through and connected to the surface of the movable sleeves 19. One end of one of the movable shafts 17 passes through one of the push plates 10 and... A movable gear 22 is fixedly connected. A fixed assembly for adjusting the rotation of the movable gear 22 is connected to the side wall of one of the push plates 10. The fixed assembly includes a fixed housing 23 fixedly connected to the side wall of one of the push plates 10. A fixed L-shaped plate 24 is fixedly connected to the side wall of the push plate 10.

The fixed motor 25 drives the fixed gear 26 to rotate.

[0031] Working principle: In use, first rotate the movable bolt on the movable sleeve block 19 so that the movable bolt moves away from the movable support plate 20. Then pull the movable mesh cover 21 to move away from the movable receiving mesh plate 18. Then place the material to be processed inside the movable receiving mesh plate 18. Then push the movable mesh cover 21 again so that the movable mesh cover 21 drives the movable support plate 20 to move downward along the inside of the movable sleeve block 19 so that the movable mesh cover 21 contacts the movable receiving mesh plate 18. Then rotate the movable bolt again so that the movable bolt moves closer to the movable support plate 20 and abuts against it to ensure the assembly effect.

[0032] Then, the assembly motor 6 is started, which drives the assembly screw 7 to rotate, causing the assembly slider 4 to move along the direction on the assembly screw 7. Since the assembly slider 4 is slidably installed inside the assembly groove, the assembly recess 5 on the assembly slider 4 moves. Since the assembly recess 5 is installed through the adjusting support plate 8 and the adjusting cross plate 9, it also drives the adjusting cross plate 9 to move. Then, the adjusting cross plate 9 also drives the material assembled between the movable receiving mesh plate 18 and the movable mesh cover 21 on the pushing block 12 of the pushing plate 10 to adjust to a suitable distance to ensure the lifting effect.

[0033] Then, start the fixed motor 25, which drives the fixed gear 26 to rotate. Because the fixed gear 26 meshes with the movable gear 22, it drives the movable shaft 17 and the movable receiving mesh plate 18 on the movable gear 22 to rotate. Then, the movable receiving mesh plate 18 also drives the material assembled between the movable mesh covers 21 to flip to a suitable angle to ensure the flipping effect.

[0034] Finally, the drive motor 14 on the drive support plate 13 is started, which drives the drive shaft 16 on the drive support plate 15 to rotate. Then, the drive shaft 16 slides inside the push plate 11. Next, the push plate 11 pushes the push plate 10 to move along the direction on the adjusting plate 9. Then, the push plate 10 drives the material assembled between the movable receiving mesh plate 18 and the movable mesh cover 21 on the push block 12 into the processing box 1 and into contact with the electrophoresis solution to ensure the adjustment and processing effect.
