The patent filed by SK Innovation Co Ltd. describes an apparatus and method for inserting an electrode assembly into a pouch using an articulated robot with a clamping unit. The apparatus includes a clamping unit that can clamp or unclamp the electrode assembly and an articulated robot with rotatable links to mount the clamping unit. The electrode assembly is introduced into the pouch at an angle through an open space between upper and lower pouches. The method involves preparing the pouch, opening it to create an open space, introducing the clamping unit with the electrode assembly, and withdrawing the clamping unit after insertion, all while maintaining the inclined orientation of the electrode assembly.
The apparatus includes a clamping unit with a base, fixed fork, moving fork, and pusher to facilitate the insertion process. The pouch consists of upper and lower pouches connected by a hinge, with the electrode assembly being introduced through the open space facing the hinge. The method further details the steps involved in withdrawing the clamping unit, which includes unclamping the electrode assembly, pushing it into the pouch, and adjusting the inclination angle of the clamping unit during withdrawal. Additionally, the method specifies that the opening angle of the open space should be equal to or less than 90° to ensure proper insertion of the electrode assembly. Overall, the patent aims to streamline the process of inserting electrode assemblies into pouches using innovative robotic technology.
