Problems solved by technology
The traditional flattening method includes spiral flattening or flattening with a flattening stick, but in the spiral flattening method, since the spiral flattening device is provided with grooves, it is easy to cause damage to the tabs of the battery pole pieces; In the contact wrinkle removal method of the flat stick, because the battery pole piece is coated with a special coating, it is easy to cause the battery pole piece to drop powder, thus affecting the safety performance of the lithium battery
[0003] At present, there is also a method of using gas to flatten the battery pole piece. This method mainly uses a high-pressure fan to blow air on the upper and lower sides of the battery pole piece. The battery pole piece produces friction, which causes the coating on the battery pole piece to fall off, which affects the safety performance of the lithium battery

The invention discloses a flattening device and a method thereof. The flattening device comprises an air floating mechanism and an air source control mechanism, wherein a plurality of cavities are formed in the air floating mechanism; the cavities are sequentially arranged in the longitudinal direction of the air floating mechanism; each cavity is provided with an air inlet; a plurality of air blowing openings are formed in positions, corresponding to each cavity, of the upper surface of the air floating mechanism; the air blowing openings communicate with the corresponding cavities; the air source control mechanism is connected with each air inlet; and the air source control mechanism is used for providing air sources for the cavities and respectively controlling the air pressure in eachcavity. By using the technical scheme, the friction generated by battery pole pieces can be prevented, so that the damage to the battery pole pieces and the falling of coatings can be reduced; the wrinkle removal effect is achieved, so that the safety performance of a lithium battery is ensured.
Description
technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a flattening device and a method thereof. Background technique [0002] Based on the development trend of lithium batteries, the transportation of battery pole pieces is a necessary process in the manufacturing process of lithium batteries. Since the battery pole pieces are prone to wrinkles during transportation, it is necessary to eliminate the wrinkles of the battery pole pieces, generally by flattening the battery pole pieces. The traditional flattening method includes spiral flattening or flattening with a flattening stick, but in the spiral flattening method, since the spiral flattening device is provided with grooves, it is easy to cause damage to the tabs of the battery pole pieces; In the contact wrinkle removal method of the flat stick, since the battery pole piece is coated with a special coating, it is easy to cause the battery pole piece to drop powder...
