VACUUM LAMINATING DEVICE

摘要

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 centre to both sides of the laminated object, so that air bubbles are efficiently expelled out during a vacuum laminating process, and thereby de-bubbling processes are omitted and a laminating yield rate is significantly improved.
