The present invention relates to a method and an apparatus for welding a 3D bellows, and a bellows, which is provided by: repeatedly laminating a unit cell material, a second adhesion-preventing film, a different unit cell material, and a first adhesion-preventing film, corresponding to the number of unit cells to be manufactured; forming ventilation holes on the unit cell materials by pressing a hole-processing cutter on which a hole-circumference welding heater is installed onto the laminated unit cell materials and the first adhesion-preventing films, and then heating the circumference of the ventilation holes, so that the surrounding area around the ventilation holes of two neighboring unit cell materials that are not blocked by the first adhesion-preventing film are mutually welded, finishing two sides of the unit cells by positioning, on two outermost surfaces of the laminated unit cell materials, a fist finishing unit cell material and a second finishing unit cell material provided with an air injection port; and cutting the first finishing unit cell material, the unit cell materials, and the second finishing unit cell material and heating the periphery of the cut area by pressing a contour-processing cutter, so that the surrounding area around the contours of two neighboring unit cell materials that are not blocked by the second adhesion-preventing film are mutually welded. Accordingly, a plurality of unit cells can be manufactured with two rounds of punching work, the unit cells can be conjoined, and the inside of the unit cells can be connected, thereby enabling mass production and significant reduction of manufacturing cost. |
