Abstract

A device for folding a pouch having first and second cup parts, first and second circumferential parts formed flat along circumferences thereof, respectively, includes: lower and upper nests on which the first and second cup parts are seated; first and second guides fixed to the lower and upper nests and having first and second protrusions protruding upwardly therefrom, the first and second protrusions in close contact with each other forming a support protrusion; and a pressing part allowing a connection part of the first and second circumferential parts to be in close contact with the support protrusion when the first and the second cup parts are seated on the lower and the upper nests, respectively, wherein when the pressing part causes the connection part and the support protrusion to be in contact, the upper nest rotates so that the second cup part is folded onto the first cup part.

Claims16

Dependent claims

A device for folding a pouch having a first cup part and a second cup part, each of the first cup part and the second cup part having a concavely recessed shape to accommodate an electrode assembly, a first circumferential part formed flat along a circumference of the first cup part, a second circumferential part formed flat along a circumference of the second cup part, and a connection part connecting the first circumferential part and the second circumferential part, the device comprising,

a lower nest on which the first cup part is configured to be seated;
an upper nest on which the second cup part is configured to be seated;
a guide comprising a first guide fixed to the lower nest and having a first protrusion protruding upwardly therefrom, and a second guide fixed to the upper nest and having a second protrusion protruding upwardly therefrom, the first protrusion and the second protrusion in close contact with each other to form a support protrusion;
and
a pressing part that allows the connection part to be in close contact with the support protrusion when the first cup part and the second cup part are seated on the lower nest and the upper nest, respectively,
wherein, in a state where the pressing part allows the connection part to be in close contact with the support protrusion, the upper nest is configured to rotate so that the second cup part is folded onto the first cup part.
