Problems solved by technology

[0003] In the public document with the publication number CN108405962A, a pole piece cutting device is disclosed. The design structure is simple, convenient and quick to operate, and it is convenient to install the cutting knives. At the same time, the distance between the cutting knives can be quickly adjusted to suit different sizes. The pole piece cutting operation improves the scope of use; however, when the pole piece is cut, the device cannot simultaneously adjust the precise spacing of multiple cutters, and the debris generated during cutting will be scattered around, making it difficult to clean Very troublesome and time-consuming

Abstract

The invention discloses a pole pi machining process for battery production. The pole pi machining process for battery production comprises the steps of a, slurry coating, specifically, driving a coating roller to rotate to drive slurry and transferring the slurry onto a base material through rotating of a backing roller or the coating roller; b, pole piece roll-pressing, specifically, feeding a pole piece into the gap between the two rollers and compacting a coating under the action of the rollers; c, pole piece slitting, specifically, slitting the pole piece into pieces with the required width through a pole piece slitting device; and d, pole piece drying, specifically, feeding the slit pole pieces into a heating box to be heated and dried. Through arrangement of the structure, the distance between cutting blades can be automatically adjusted under driving of first driving part to transmission parts; meanwhile, scraps produced during cutting can be automatically cleaned through a dustcollection device to prevent the scraps from flying around, and the cleanliness of a machining environment is improved.

Description

technical field [0001] The invention belongs to the technical field of battery pole piece processing, and in particular relates to a pole piece manufacturing process for battery production. Background technique [0002] With the rapid development of the new energy industry, the demand for soft-pack lithium-ion batteries and aluminum-cased batteries is increasing. The manufacturing process of soft-pack lithium batteries usually includes pulping, coating, assembly and chemical formation; during the assembly process, the coated electrode sheets need to be cut. [0003] In the public document with the publication number CN108405962A, a pole piece cutting device is disclosed. The design structure is simple, convenient and quick to operate, and it is convenient to install the cutting knives. At the same time, the distance between the cutting knives can be quickly adjusted to suit different sizes. The pole piece cutting operation improves the scope of use; however, when the pole p...
