Abstract
Disclosed is a method for inspecting electrode alignment of a battery cell that inspects an alignment state of a jelly roll including a negative electrode plate, a positive electrode plate, and a separator of the battery cell. The method includes: supplying the separator to fix both portions of the separator to a stack table using a first gripper and a second gripper; rotating the stack table to face one side; stacking the negative electrode plate on the separator; fixing the negative electrode plate on the separator; obtaining a first image by photographing the negative electrode plate and by calculating a position of the negative electrode plate; rotating the stack table to face the other side and supplying the separator on the negative electrode plate after the second gripper is released; stacking the positive electrode plate on the separator; and fixing the positive electrode plate on the separator.
