Description

Technical Field

[0001] The invention relates to the technical field of lithium ion batteries, in particular to a device for improving the rolling and bonding of positive and negative pole pieces of lithium ion batteries. Background Art

[0002] Rolling the pole piece can increase the surface density of the pole piece, even out the thickness of the pole piece, increase the mechanical strength of the pole piece, and improve the conductivity of the pole piece. In order to increase the energy density of lithium-ion batteries, it is necessary to increase the pressure of pole piece rolling and increase the surface density of the pole piece coating. When the pressure of the rolling process is increased, the coating on the pole piece is prone to fall off and stick to the pressure roller. When the roller sticks, the coating on the roller must be wiped off, otherwise the problem of roller sticking will become more and more serious, affecting the quality and rolling rate of the rolled pole piece, and reducing the battery quality and production efficiency.

[0003] Currently, the roller is cleaned manually or with a scraper to wipe off the coating adhered to the roller. During this process, foreign matter is easily introduced to the surface of the electrode by hand or with a scraper, causing contamination or even damage to the electrode.

[0039] Before rolling the lithium-ion battery pole piece, start the plasma cleaner 16 to treat the lithium-ion positive and negative pole pieces, and use the high-energy particles in the plasma to react with the coating on the pole piece to decompose the organic matter on the coating surface. After the organic matter is decomposed, it reacts with the oxidant in the plasma and further degrades into low-molecular gas and inorganic matter. Through the plasma treatment, the binder on the surface of the pole piece coating is decomposed, the adhesion between the pole piece coating and the roller is reduced, and the occurrence of the roller sticking phenomenon is suppressed;

A first fixing frame 5 is fixedly connected to the side wall of the support plate 1. The side wall of the first fixing frame 5 is fixedly connected to the waste gas treatment cylinder 18 through a bracket. The waste gas treatment cylinder 18 is communicated with the gas collecting cylinder 17 through an air delivery box 23. The top wall of the waste gas treatment cylinder 18 is connected to a rotating cylinder 20 through a bearing. A spray head 22 is arranged at one end of the rotating cylinder 20 located inside the waste gas treatment cylinder 18. A circulation pipe 19 is fixedly connected to the outer side wall of the waste gas treatment cylinder 18. A circulation pump is arranged on the circulation pipe 19. Water inlets and outlets are formed on the side wall of the circulation pipe 19.

After drying through the drying plate 21, it is discharged from the exhaust hole of the waste gas treatment cylinder 18. The rotating cylinder 20 drives the spray head 22 to rotate and spray, which can make the catalyst fully contact and react with the harmful gas.

The first rotating shaft 14 is connected to the rotating cylinder 20 through a synchronous belt and a synchronous pulley.

The first rotating shaft 14 drives the rotating cylinder 20 to rotate through a synchronous belt and a synchronous pulley.

In the present invention, one motor 7 can simultaneously drive the key cylinder 15, the rotating cylinder 20, and the second rotating shaft 26 to rotate, so that the rotation and spraying of the catalyst, the rotation and cleaning of the pole piece, and the rotation of the fan blade 27 to generate negative pressure for gas collection can share one motor drive, saving the cost of providing an additional motor and helping to reduce the weight of the equipment.

[0049] In one embodiment, as Figure 1 and Figure 4 shown in Figure 4 , a spring is fixedly connected between the second fixing frame 8 and the adaptive plate 9. The spring drives the roller 12 to abut against the pole piece.

[0050] The above embodiment discloses a device for improving the roller sticking of the positive and negative pole pieces of lithium-ion batteries. Before rolling the pole pieces of lithium-ion batteries, the plasma cleaner 16 is started to treat the positive and negative pole pieces of lithium-ion batteries by the plasma cleaner 16. The high-energy particles in the plasma react with the coating on the pole pieces to decompose the organic matter on the surface of the coating. After the organic matter is decomposed, it reacts with the oxidant in the plasma and further degrades into low-molecular gas and inorganic matter. The plasma treatment decomposes the binder on the surface of the pole piece coating, reduces the adhesion between the pole piece coating and the roller, and suppresses the occurrence of the roller sticking phenomenon.

[0051] The motor 7 is started, and the key cylinder 15 is driven to rotate through the driving assembly 29, and the key cylinder 15 drives the keyway shaft 10 to rotate, and the keyway shaft 10 drives the plasma cleaner 16 to rotate, so that the plasma cleaner 16 performs rotational cleaning on both sides of the lithium-ion battery pole piece, thereby avoiding the situation where the pole piece is not cleaned locally due to the gap between the plasma emitters;

[0052] The two rollers 12 are in contact with the pole pieces to drive the two adaptive plates 9 to move. The two adaptive plates 9 can drive the two keyway shafts 10 to move. The distance between the two plasma cleaners 16 and the pole pieces can be adaptively controlled according to the pole pieces of different thicknesses. Manual adjustment is no longer required, which is convenient for use.

[0053] The fan blades 27 are driven to rotate by the second rotating shaft 26 to generate negative pressure, and the harmful gas generated by the reaction between the high-energy particles in the plasma and the coating on the pole piece of the plasma cleaner 16 is sucked into the exhaust gas treatment tube 18 through the gas delivery box 23, and the harmful gas is centrally treated to prevent the staff from inhaling the harmful gas for a long time;

[0054] After the harmful gas enters the exhaust gas treatment tube 18, the catalyst is poured into the water inlet of the circulation pipe 19, and the circulating flow is carried out under the action of the circulation pump to catalytically oxidize the harmful gas and convert it into water, carbon dioxide and other harmless gases. After drying by the drying plate 21, it is discharged from the exhaust hole of the exhaust gas treatment tube 18. The rotating tube 20 drives the nozzle 22 to rotate and spray, so that the catalyst and the harmful gas can fully contact and react;

[0055] Start the motor 7, the motor 7 drives the first rotating shaft 14 to rotate, the first rotating shaft 14 drives the two key cylinders 15 to rotate through the synchronous belt and the synchronous pulley, the first rotating shaft 14 drives the rotating cylinder 20 to rotate through the synchronous belt and the synchronous pulley, the first rotating shaft 14 drives the second rotating shaft 26 to rotate through the bevel gear part 25. The present invention can simultaneously drive the key cylinder 15, the rotating cylinder 20, and the second rotating shaft 26 to rotate through a motor 7, so that the rotating spraying of catalyst, the rotating cleaning pole piece, and the rotating fan blades 27 to generate negative pressure for air collection can be driven by a common motor, which saves the cost of providing an additional motor and helps to reduce the weight of the equipment.

[0056] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
