[0002] The battery substrate refers to the part used as a supporting structure in the battery system. It can carry active materials and provide a platform for electrical connections. In lithium-ion batteries, the battery substrate usually refers to the carrier of the current collector, which can be a thin sheet made of metal foil or other conductive materials.

The width of the AGM coating paper is adapted to the width of the battery substrate, and then the cutting knife cuts the AGM coating paper. Compared with coated paper, the porosity of AGM coating paper is high, and the curing process of the battery substrate is faster, which can reduce the curing and drying time.

[0018] A processing method of a coating paper device for a battery substrate comprises the following steps:

At the same time, to prevent excess AGM coating paper 5 from moving with the battery substrate 34 through the unloading assembly, the unloading controller 8 moves along the bottom of the unloading machine 7 to the storage plate 10, and the lifting suction cup 9 moves downward to place the battery substrate 34 on the storage plate 10, and then the unloading controller 8 continues to move toward the direction of the storage plate 10, and places the battery substrate 34 adsorbed by the second lifting suction cup 9 on the storage plate 10, thereby improving the working efficiency of unloading the battery substrate 34.

[0048] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0049] In the first step, the battery substrate 34 is loaded. The staff adjusts the limit assembly according to the size of the battery substrate 34 and controls the adjustment rod 13 to rotate. The adjustment rod 13 rotates and moves through the threaded connection with the adjustment hole 18. The adjustment rod 13 drives the rotating plate 19 to rotate in the rotating groove 20. The rotating plate 19 resists the rotating groove 20 to drive the limit plate 14 to move. The staff places the battery substrate 34 on the conveyor belt 1 along the limit plate 14. The conveyor belt 1 can rotate along the inner wall of the side plate 2 to transport the battery substrate 34.

[0050] In the second step, the battery substrate 34 is coated, the motor 3 drives the pressure roller 35 to rotate, the pressure roller 35 pulls the AGM coated paper 5 to move, the AGM coated paper 5 is coated on the battery substrate 34, the pressure roller 35 is pressed on the top of the battery substrate 34, and at the same time, the AGM coated paper 5 is stored on the storage shaft 4, and the AGM coated paper 5 is rotated and unloaded on the storage shaft 4.

[0051] In the third step, the excess AGM coating paper 5 coated on the battery substrate 34 is cut. The transverse cutting mechanism first transversely cuts the AGM coating paper 5 in the length direction of the battery substrate 34. The transverse cutting knife 36 slides along the bottom end of the pressure roller 35. The transverse cutting knife 36 cuts the AGM coating paper 5 transversely, thereby separating the AGM coating paper 5 on the battery substrate 34 and the AGM coating paper 5 on the pressure roller 35. The vertical cutting knife 27 fixed on the vertical cutting seat 26 cuts the excess AGM coating paper 5 at both ends of the battery substrate 34 in the width direction.

[0052] In the fourth step, the battery substrate 34 is unloaded. The unloading controller 8 moves at the bottom of the unloading machine 7. The unloading controller 8 controls the lifting suction cup 9 to adsorb the two groups of battery substrates 34. The unloading controller 8 moves along the bottom of the unloading machine 7 to the storage plate 10. The lifting suction cup 9 moves downward to place the battery substrate 34 on the storage plate 10. Then the unloading controller 8 continues to move toward the direction of the storage plate 10 and places the battery substrate 34 adsorbed by the second lifting suction cup 9 on the storage plate 10.

[0053] The limiting component limits the battery substrate 34 during loading, ensuring that the battery substrate 34 can move in parallel to the length direction of the side plate 2, thereby ensuring the accuracy of the battery substrate 34 for lamination. The limiting component can limit the two groups of battery substrates 34, further improving the working efficiency of the equipment;

[0054] When the size of the battery substrate 34 changes, the coating component fully coats the battery substrate 34 to avoid the problem of long production cycle caused by replacing the film material that matches the battery substrate 34. The cutting component first cuts the excess film material on the battery substrate 34 horizontally to ensure that the battery substrate 34 is fully matched with the film material in the length direction. Then, the cutting component cuts the battery substrate 34 vertically to ensure that the battery substrate 34 is fully matched with the film material in the width direction. Finally, the battery substrate 34 is detached from the conveyor belt 1 through the unloading component. The coating component and the cutting component cooperate to realize the coating of battery substrates 34 of different sizes. At the same time, two battery substrates 34 can be coated, which improves work efficiency.

[0055] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention.
