Abstract
A battery cell electrode alignment inspection method for inspecting an alignment state of a jelly roll configured of negative and positive electrode plates and a separator of a battery cell includes: obtaining electrode vision image data by capturing vision images of individual negative and positive electrode plates configuring the jelly roll by a vision camera; obtaining dimensional data of the individual negative and positive electrode plates; storing the obtained dimensional data of the individual negative and positive electrode plates; marking a cell barcode for identification of the jelly roll; scanning the cell barcode to receive dimensional data of individual negative and positive electrode plates; X-ray-capturing the jelly roll to obtain X-ray image data of the individual negative and positive electrode plates; and substituting the dimensional data of the individual negative and positive electrode plates to the obtained X-ray images of the individual negative and positive electrode plates.
