Apparatus for manufacturing secondary battery and electrode plate cutting unit for manufacturing secondary battery

Abstract

The present disclosure provides an apparatus for manufacturing a secondary battery and an electrode plate cutting unit, which can extend an operating lifetime by a factor of two or more, reduce process costs, improve productivity, and maintain constant cutting performance, and are very useful in a process requiring a high-quality cutting operation. The apparatus includes a transfer part configured to move an electrode plate, a winding part configured to wind the electrode plate transferred by the transfer part, an ascending/descending upper cutter which is installed above the transport path to allow a mounting direction to be changed and on which is formed an upper cutter blade, a stripper positioned below the electrode plate and configured to support the electrode plate when the electrode plate is cut, a fixed body configured to elastically support the stripper, and a lower cutter which is supported on a side portion of the fixed body and on which a lower cutter blade is formed, wherein at least one of the upper cutter blade and the lower cutter blade includes two or more blades.

Dependencies are inferred from the claim text.
