Description

Lamination apparatus and lamination method {Apparatus for lamination and method of lamination}

The present invention relates to a lamination apparatus and a lamination method.

The lamination device is a device that bonds a glass to a panel on which an image is displayed or laminates a film to glass. The glass may include a flat portion and a curved portion. The curved portion may be disposed on the upper, lower, left, and right edges of the glass. The lamination device may comprise a pad. The pad performs a role of bonding the film to the glass by pressing the film while the glass and the film are aligned. The pad may perform lamination starting from the flat portion and toward the curved portion.

This lamination operation takes place in a vacuum chamber. Further, in the chamber, alignment devices for aligning the glass and the film are provided in the chamber. The interior space of the chamber needs a space for accommodating an alignment device or a transfer device. Thus, the size of the chamber increases. As the size of the chamber increases, the space for performing the vacuum operation increases, so there is a problem that the lamination process time (process time) becomes longer.
