Corrugation removal device for rolling of battery pole plate

Abstract

The invention discloses a corrugation removal device for rolling of a battery pole plate. The corrugation removal device comprises a main body installation framework and a pole plate, wherein the mainbody installation framework comprises a side plate A, a side plate B and a bottom plate, the side plate A and the side plate B are respectively arranged at two sides of the bottom plate, a tension roller is arranged at an edge position between the side plate A and the side plate B, an auxiliary roller is arranged between the side plate A and the side plate B and is arranged at a position of the same plane with the tension roller, a floating roller is arranged at a position obliquely above the tension roller between the side plate A and the side plate B, and floating roller swinging arms are arranged at positions, arranged at two ends of the floating rollers, on the side plates A and the side plate B. The corrugation removal device for rolling of the battery pole plate is compact in structure, is flexible to install and can be arranged at a feeding hole or a discharging hole of a rolling machine, rolling and corrugation removal are completed in one time, the process time of the whole production line is not occupied, the production rate is high, the normal production of a subsequence process is ensured, dual-closed loop control is employed, a tension force is stable, the pole plateis uniformly extended, and stable production is achieved.

Description

technical field [0001] The invention relates to the technical field of manufacturing lithium-ion battery pole pieces, in particular to a device for removing wrinkles by rolling battery pole pieces. Background technique [0002] In the production of lithium-ion battery pole pieces, there is a continuous coating process. The positive or negative electrode materials of the battery are evenly coated on the current collector. The current collector is generally aluminum foil or copper foil, and the thickness is generally 0.006mm-0.013mm. Between mm; after coating, a continuous strip structure is formed on the current collector, continuous and uninterrupted in the length direction of the pole piece, and distributed in equal or unequal intervals in the width direction; generally there is no coated area It is called the foil area, and the other part is called the coating area; when rolling the pole piece with this coating structure, the pole piece has serious wrinkles; the reason is ...
