Abstract
An electrode plate deviation correction method includes collecting, by sensors, deviation data of an edge of an electrode plate relative to a preset boundary, determining a deviation correction displacement of the electrode plate according to the deviation data, controlling, according to the deviation correction displacement, an unwinding apparatus for the electrode plate to adjust a position of the electrode plate so that the deviation data of the electrode plate relative to the preset boundary is within a target range.
