Abstract

A misalignment detection method and apparatus for battery tabs, and a battery electrode plate winding system, are disclosed. The method includes winding a battery electrode plate onto a winding shaft. For an Nth layer (where N is an integer greater than zero) of the electrode plate section wound on the winding shaft, an image including a battery tab region is acquired during the winding period. A relative positional relationship between a battery tab and a reference part on the winding shaft is determined from the image. Based on this positional relationship and the layer number of the Nth electrode plate section, a misalignment amount of the battery tab is calculated for when the wound electrode plate is later pressed into a battery cell. The method enables real-time monitoring of tab alignment during winding, improving accuracy in battery cell assembly.
