Abstract: A strip defect repair device configured to repair a coating defect of a strip and includes a detection module, a transfer module, and a repair module. The detection module is configured to detect the coating defect of the strip and feed back a position signal corresponding to the coating defect. The transfer module is configured to respond to the position signal and drive the repair module to move to a position corresponding to the coating defect, and the repair module is configured to add a supplementary material to the coating defect so as to repair the coating defect.

Abstract: Disclosed is method and device for forming an electrode plate. The method includes: performing tab cutting on a substrate so that the substrate forms a body portion, an edge portion connecting to the body portion, and a plurality of tabs that connect to the body portion but are separated from the edge portion; and performing edge portion cutting on the substrate to separate the edge portion from the body portion. The electrode plate is formed in two steps. First, the tab and the edge portion are separated, so that in the process of cutting, impact of vibration of the edge portion on the tab is small, greatly reducing the risk of deformation of the tab caused by vibration of the edge portion and damage to the tab caused by being pulled by the edge portion. Second, edge portion cutting separates the edge portion from the body portion.
