  • Patent number: 10957944
    Abstract: Provided are an electrode aligned state inspection system and method of imaging a stacking process of an electrode plate, inspecting a position of the electrode plate, and determining whether or not a product is defective. When a misalignment occurs during the stacking process of a cathode plate, an anode plate, and a separator, an operator immediately recognizes the occurrence of the misalignment, and therefore, it is possible to improve a quality reliability of the electrode assembly. In addition, since it is determined whether or not the product is defective during a production process of the electrode assembly, an amount of waste may be reduced. The video data obtained by the imaging of the production process of the electrode assembly is automatically stored, and therefore, the data may be used as data that may be checked later when the quality is checked and the defective product is produced.
