Lamination device

Abstract

A lamination device of the present invention includes a pattern roller part embodying a pattern on an electrode assembly, wherein the pattern roller part includes a rotation roller disposed on a surface of the electrode assembly to emit heat and a pattern cover wound around an outer circumferential surface of the rotation roller and partially pressing the surface of the electrode assembly together with the heat transferred from the rotation roller to embody a pattern, and the pattern cover includes a pattern film wound around the outer circumferential surface of the rotation roller and a deformation member disposed on an inner surface of the pattern film to wind the pattern film around the outer circumferential surface of the rotation roller while being deformed by the heat transferred from the rotation roller.
