Abstract

The present disclosure provides an apparatus for manufacturing a secondary battery and an electrode plate cutting unit, which are capable of preventing cracks or foreign substances from occurring in a mixture portion and preventing an active material from being transferred to a separator by reducing the load applied to a load concentration area of an electrode plate while the electrode plate is cut. The apparatus for manufacturing a secondary battery includes a transport unit configured to transport an electrode plate, a winding unit configured to wind the electrode plate, and a cutting unit having an upper cutter, a lower cutter, and a stripper installed on a side portion of the lower cutter, that supports the electrode plate when the upper cutter moves downwardly to transmit to the electrode plate a reaction force corresponding to a downward force of the upper cutter, and provides a stress relief space which prevents the reaction force from being transmitted to a portion of the electrode plate to which shear forces due to the upper cutter and the lower cutter are applied.
