Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to an integrated device for multi-level nano-dispersion and coating of lithium battery anode materials. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental conditions, which is why lithium-ion batteries were not widely used for a long time. However, with the development of science and technology and the emergence of technological products such as mobile phone batteries and new energy vehicles, the application of lithium-ion batteries has been promoted, and now lithium-ion batteries have gradually become mainstream. A lithium-ion battery consists of a positive electrode and a negative electrode. The positive electrode slurry is composed of binders, conductive agents, and positive electrode materials, while the negative electrode slurry is composed of binders, graphite carbon powder, etc. In order to ensure the processing and production quality of lithium-ion batteries, the liquids and solids of the positive and negative electrode slurries need to undergo thorough mixing, dissolution, and dispersion treatment.

[0003] After searching, it was found that application number CN202311472631.9, entitled "A Lithium-ion Battery Material Mixing Device with a Feeding Channel," proposes a novel dispersion device for dispersing lithium-ion battery anode materials. However, during the production of lithium-ion battery anode materials, it is necessary to coat the dispersed lithium-ion battery anode materials. The coating material is uniformly wrapped on the surface of the lithium-ion battery anode materials through mixing to provide better electron exchange capacity. After dispersion, this application still requires manual transfer to a coating machine for coating operation, which is cumbersome and affects production efficiency. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To achieve the aforementioned advantages of improved production efficiency and ease of use, while also possessing both dispersing and coating functions, the specific technical solution adopted by this utility model is as follows: An integrated device for multi-level nano-dispersion and coating of lithium battery anode materials includes a material tank and a base plate.

A brake motor is fixedly mounted on one side surface of the side frame, and the output end of the brake motor is fixedly connected to one end of a shaft.

When dispersing lithium battery anode materials, the staff can put the lithium battery anode materials into the material tank. The first drive motor drives the nano-dispersing head to rotate and disperse the lithium battery anode materials. After the dispersion is completed, the staff can start the brake motor to drive the shaft and the material tank to deflect at a certain angle.

Then, it is dispersed again through the nano-dispersing head to complete multi-stage dispersion, which improves dispersion efficiency and thus improves work efficiency. Attached Figure Description

Figure 1-4 As shown, the integrated equipment for multi-level nano-dispersion and coating of lithium battery anode materials according to an embodiment of the present invention includes a material tank 1 and a base plate 16. A side frame 15 is fixedly installed on the top surface of the base plate 16, and the material tank 1 is disposed between the side frames 15. A side ring 9 is fixedly installed on the outer wall of the material tank 1. An outer ring seat 8 is rotatably sleeved on the outer side of the side ring 9. Both the side ring 9 and the outer ring seat 8 are annular structures, and the surface of the outer ring seat 8 is rotatably connected to the side frame 15 via a shaft 17. A main shaft 4 is connected through the top surface of the material tank 1, and a nano-dispersion head 13 is fixedly installed on the bottom surface of the main shaft 4. A lifting platform 2 is disposed above the material tank 1, and a first drive motor 3 is fixedly installed on the top surface of the lifting platform 2. The output end of the first drive motor 3 is fixedly connected to the top surface of the main shaft 4.

A brake motor 18 is fixedly mounted on one side surface of side frame 15, and the output end of brake motor 18 is fixedly connected to one end of shaft 17. When dispersing lithium battery negative electrode material, the operator can put the lithium battery negative electrode material into the material tank 1. The first drive motor 3 drives the nano-dispersing head 13 to rotate, dispersing the lithium battery negative electrode material. After dispersion, the operator can start brake motor 18 to drive shaft 17 and material tank 1 to deflect at a certain angle. Then, start electric cylinder 5 to extend, driving nano-dispersing head 13 to move upward, so that coating material can be put into material tank 1. Then, start second drive motor 11, which drives drive gear 12 to rotate, thereby driving driven gear 10 and material tank 1 to tilt and rotate, so that coating material is evenly coated on the surface of lithium battery negative electrode raw material, completing dispersion and coating, eliminating the trouble of material transfer, and improving the convenience of use and work efficiency.

[0022] In one embodiment, the two ends of the electric cylinder 5 are fixedly connected to the bottom surface of the lifting platform 2 and the top surface of the material tank 1, respectively. A guide rod 6 is slidably connected through the surface of the lifting platform 2, and the bottom surface of the guide rod 6 is fixedly connected to the top surface of the material tank 1. The electric cylinder 5 drives the lifting platform 2 to rise and fall, thereby driving the nano-dispersing head 13 to rise and fall. The guide rod 6 serves as a guide for the lifting of the lifting platform 2, improving the stability of the lifting of the lifting platform 2.

[0023] In one embodiment, a feeding port 7 is provided on the top surface of the material tank 1 on one side of the electric cylinder 5 to facilitate feeding.

[0024] In one embodiment, a valve 14 is installed at the bottom opening of the material tank 1 to facilitate unloading.

[0025] In one embodiment, a blade 19 is fixedly mounted on the outer surface of the main shaft 4 above the nano-dispersing head 13, and multiple sets of blades 19 are distributed at equal angles along the central axis of the main shaft 4. When feeding lithium battery anode material, the first drive motor 3 can be started, and the first drive motor 3 drives the blades 19 to rotate, so as to initially disperse the lithium battery anode material. Subsequently, it is dispersed again through the nano-dispersing head 13 to complete multi-stage dispersion, thereby improving dispersion efficiency and thus improving work efficiency.

[0026] In one embodiment, the vertical cross-section of the edge ring 9 is T-shaped, and the edge ring 9 is polished to prevent separation from the outer ring seat 8.

[0028] In one embodiment, the second drive motor 11 is a servo motor with a swing mechanism, which facilitates the reciprocating oblique rotation of the material tank 1 for the covering operation, and at the same time facilitates the wiring of the first drive motor 3 and the electric cylinder 5.

[0029] Working principle: When dispersing lithium-ion battery anode materials, the operator can put the lithium-ion battery anode material into the material tank 1. The first drive motor 3 drives the nano-dispersing head 13 to rotate, dispersing the lithium-ion battery anode material. After dispersion, the operator can start the brake motor 18 to drive the shaft 17 and the material tank 1 to deflect at a certain angle. Then, the starter cylinder 5 extends, driving the nano-dispersing head 13 to move upward, so that the coating material can be put into the material tank 1. Then, the second drive motor 11 is started, which drives the drive gear 12 to rotate, thereby driving the driven gear 10 and the material tank 1 to rotate. The tilting and rotation of the tank 1 allows the coating material to be evenly coated on the surface of the lithium battery anode material, completing the dispersion and coating process. This eliminates the hassle of material transfer, improving ease of use and work efficiency. Meanwhile, the blade 19 is located above the nano-dispersing head 13. When feeding the lithium battery anode material, the first drive motor 3 can be activated. The first drive motor 3 drives the blade 19 to rotate, performing initial dispersion of the lithium battery anode material. Subsequently, it undergoes secondary dispersion through the nano-dispersing head 13, completing multi-stage dispersion, improving dispersion efficiency, and thus improving work efficiency.
