Description

Can Transfer Device and Can Transfer Method Various embodiments of the present disclosure relate to a can conveying device and a can conveying method. Rechargeable batteries are widely used in portable mobile devices such as digital cameras, mobile phones, and laptops due to their rechargeable and dischargeable capabilities. In particular, with the rapid development of the electrical, electronic, telecommunications, and computer industries in recent years, the demand for high-performance and high-stability rechargeable batteries is increasing even further. Generally, depending on the structure of the electrode assembly, the secondary battery may include a jelly-roll electrode assembly in which long sheet-type positive and negative electrodes are wound with a separator in between, a stack-type electrode assembly in which a plurality of positive and negative electrodes cut into units of a predetermined size are sequentially stacked with a separator in between, and a stack/folding-type electrode assembly in which bicells or full cells in which positive and negative electrodes of a predetermined unit are stacked with a separator in between are wound. In addition, depending on the shape of the battery case, the secondary battery may be composed of a cylindrical secondary battery in which the electrode assembly is embedded in a cylindrical metal can, a prismatic secondary battery in which the electrode assembly is embedded in a prismatic metal can, a pouch-type secondary battery in which the electrode assembly is embedded in a pouch-type case made of an aluminum laminate sheet, etc. Meanwhile, in the manufacturing process of a cylindrical secondary battery, the can must be transported from a first position toward a second position to accommodate the electrode assembly. To transport the can, a transport device is used that secures the can by contacting the inner circumference of the can from inside the can. However, when the can is fixed in a manner that contacts the inner surface of the can and the can is transported, damage may be inflicted on the inner surface of the can due to friction with the transport device.
