Abstract: Method and apparatus for detecting a defect on an insulation coating on a battery electrode plate are disclosed. The method includes: obtaining an electrode plate image obtained by photographing an electrode plate, where the electrode plate image includes at least one complete electrode plate; determining an insulation coating region and a tab region in the electrode plate image; determining a defect detection region in the insulation coating region in the electrode plate image based on the insulation coating region and the tab region; and performing defect detection on the defect detection region to obtain a defect detection result. The method implements detection on the insulation coating on the electrode plate before combination, and can detect whether a defect exists in the insulation coating region.

Abstract: Embodiments of the present application provide an apparatus and a method for manufacturing an electrode assembly. The apparatus includes a driving portion, used for driving pole pieces to fall them from the driving portion; and a first support portion, arranged below the driving portion, and used for receiving the falling pole pieces, so that the pole pieces are stacked on the first support portion. The distance between an initial position of the upper surface of the first support portion and the driving portion being in a range of W to 2W. The initial position is the position of the upper surface of the first support portion when receiving the first pole piece of the electrode assembly, and W is the length of each pole piece. The apparatus can effectively stack the pole pieces to obtain an electrode assembly, and has high stacking efficiency.
