Coating size correction method and apparatus, device, storage medium, and program product

A method for correcting a coating size of an electrode plate, performed by a coating size correction system that comprises an image acquisition apparatus and a coating size correction apparatus, the method comprising:

• acquiring, by the image acquisition apparatus, a first wet coating width and a first dry coating width of a first coating region on the electrode plate;
• obtaining, by the coating size correction apparatus, a first deviation between the first dry coating width and a preset coating width, and a second deviation between the first wet coating width and the first dry coating width;
• determining by the coating size correction apparatus, whether the first deviation meets a preset requirement, wherein the preset requirement is that the first deviation is within a predetermined range;
• and
• when the first deviation fails to meet the preset requirement determining, by the coating size correction apparatus, a first correction amount based on the first deviation and the second deviation;
• wherein a distance between a spraying apparatus and the electrode plate is adjusted according to the determined first correction amount.
