Abstract
The present application provides a deviation-correcting method and apparatus for double-sided coating, and relates to the technical field of manufacturing of batteries. The method includes: acquiring a first distance between an edge of a coating area on a first surface of an electrode plate substrate and an edge of the electrode plate substrate from a deviation-correcting cross section; acquiring a second distance between an edge of a coating area on a second surface of the electrode plate substrate and the edge of the electrode plate substrate from the deviation-correcting cross section; determining edge deviation information of the coating areas; determining a first deviation-adjusting range; and in a case that a first intersection is present in the first deviation-correcting range, determining a deviation-correcting quantity of the electrode plate substrate. According to the method, the problem of the deviation of the coating areas in the coating process can be improved.
