Abstract
Disclosed is a vacuum laminating device and a method of using such a vacuum laminating device to laminate a first object and a second object together. The vacuum laminating device comprises a first platform, a second platform, and a lifting pushrod that are receivable in a vacuum chamber; a bottom surface of the first platform is provided with a first adsorbing surface suitable for adsorbing the first object; the second platform is disposed below the first platform and configured to be movable up and down below the first platform so as to make a laminating contact with the first platform, and an upper surface of the second platform is provided with a second adsorbing surface facing the first adsorbing surface and being suitable for adsorbing the second object; and the lifting pushrod is disposed within a region where a central region of the second adsorbing surface is located, configured to be movable up and down independently below the first platform so as to push up a central portion of the second object so that the central portion make a laminating contact with the first object firstly. With the vacuum laminating device, air bubbles are expelled out from center to both sides of …
