APPARATUS FOR MANUFACTURING POUCH OF SECONDARY BATTERY

The present invention relates to an apparatus for manufacturing a pouch of a secondary battery, and more particularly, to an apparatus for manufacturing a pouch of a secondary battery, in which, when a pressure for gripping a pouch base material is applied to mold the pouch, a higher pressure may be applied to a locally required area to relieve or remove pouch wrinkles without increasing in overall pressure, thereby improving molding quality of the pouch.An apparatus for manufacturing a pouch of a secondary battery according to the present invention includes a lower die having an accommodation groove for molding a cup part of the pouch on a base surface, on which the pouch is disposed, a punch inserted into the accommodation groove of the lower die to mold the cup part of the pouch, a stripper disposed above the lower die to face the lower die and provided to press a peripheral portion of the pouch, which is disposed around a portion to be molded into the cup part of the pouch by the punch, from an upper side, and a back plate coupled to the stripper and configured to support the stripper, wherein a protruding block protruding toward the stripper is provided on a surface (S) of surfaces of the back plate, which faces the stripper.
