Description

Laser cleaning device, battery production line and battery pole piece cleaning method Technical Field The application belongs to the technical field of battery production, and particularly relates to a laser cleaning device, a battery production line and a battery pole piece cleaning method. Background In the battery manufacturing process, the laser cleaning of the battery pole piece is a key link for ensuring the quality of products, and relates to the accurate treatment of the first surface and the second surface of the battery pole piece. Because of inherent uniformity fluctuation of the battery pole piece material coating and inconsistent dust removal efficiency of the dust removal system in four directions, the cleaning parameters of the four edges of the battery pole piece need to be differently set for different surfaces. In particular, the cleaning parameters of the first side cannot be directly applied to the second side, which means that it is difficult for the same cleaning station to meet the depth requirements of both sides simultaneously. However, most of the current laser cleaning devices adopt a single-station design, and the phenomenon that the first surface and the second surface are simultaneously processed at the same station generally exists, so that the cleaning depth stability is seriously insufficient. For example, when the first side is cleaned to a depth that meets the criteria, the second side often fails to meet the criteria and vice versa, which directly results in a reduction in product yield. Disclosure of Invention The application aims to provide a laser cleaning device, a battery production line and a battery pole piece cleaning method, which can stably distinguish and process a first surface and a second surface, avoid cleaning parameter conflict and improve cleaning depth stability and product qualification rate. To achieve the above object, according to a first aspect of the embodiments of the present application, there is provided a laser cleaning device, including a movable stage structure, a detection mechanism, a laser cleaning mechanism and a controller, where the movable stage structure includes a slide rail assembly and a stage module disposed on the slide rail assembly, the stage module is capable of reciprocating along an extending direction of the slide rail assembly, the slide rail assembly has a first station section, a second station section and a third station section sequentially connected along the extending direction of the slide rail assembly, a product to be cleaned is disposed on the stage module when the stage module is disposed on the first station section, the stage module includes a plurality of slide rails disposed side by side, the plurality of slide rails are disposed on the plurality of slide rails in one-to-one correspondence, a product to be cleaned surface disposed on at least one of the slide rails is a first surface, a product to be cleaned surface disposed on the rest of the slide rails is a second surface, the detection mechanism is disposed corresponding to the second station section, the detection mechanism is used for detecting the product transferred to the second station section, the laser cleaning mechanism is disposed corresponding to the third station section, and the laser cleaning mechanism is connected to the laser cleaning mechanism and the controller, respectively. According to the laser cleaning device provided by the application, products on the first surface and the second surface are processed by arranging the plurality of sliding rails and the carrier plate in a distinguishing way, and the stable cleaning is realized by combining the detection and cleaning mechanism, so that the first surface and the second surface can be processed in a stable distinguishing way, the conflict of cleaning parameters is avoided, and the cleaning depth stability and the product qualification rate are improved.
