Title:
BONDING METHOD FOR FILM OF LENS
Document Type and Number:
WIPO Patent Application WO/2022/105909
Kind Code:
A1
Abstract:
A bonding method for a film (200) of a lens (300), and a film bonding apparatus (100) for a lens (300). A first jig (10) and a second jig (20) are controlled to move relatively, such that the lens (300) is gradually bonded to the film (200) from a middle position to an edge position, which can reduce generation of bubbles between the film (200) and the lens (300) so as to achieve a good film bonding effect. In addition, it is not necessary to treat the film (200) in advance, and it is also not necessary to form the film (200) and then perform injection molding to obtain the lens (300), so as to ensure the optical performance or mechanical performance of the bonded film (200), and the simple bonding method for the film (200) can obtain a desired optical element, and ensure the optical performance and mechanical performance of the optical element obtained after bonding the film (200) to the lens (300).
