Abstract

The present disclosure provides an apparatus for manufacturing a secondary battery and an electrode plate cutting unit for a secondary battery, in which, since a lower cutter is fixedly pressed using a high-strength spring, the lower cutter has good fixing strength and cutting precision is stably maintained, thereby preventing deintercalation of an active material when cutting an electrode plate and improving quality of a cut surface. The apparatus includes a transport unit configured to transport an electrode plate, which is a cutting target, along a transport path, a winding unit configured to receive and wind a cut electrode plate transported by the transport unit, and a cutting unit having an upper cutter installed above the transport path to move upwardly and downwardly, a fixing body fixed below the transport path to provide support strength, a lower cutter supported by the fixing body and configured to cut the electrode plate through cross motion with the upper cutter, and an elastic support elastically supporting the lower cutter toward the fixing body to maintain a fixed state of the lower cutter with respect to the fixing body.
