Abstract
A method for bonding a film to a lens and a device for bonding a film to a lens includes a first jig and a second jig that are controlled to move relative to each other, to gradually bond a middle position to an edge position on the lens to the film, so that bubbles between the film and the lens can be reduced, and a good film bonding effect can be achieved. In addition, the method can be performed without processing the film in advance, and obtaining the lens through injection molding after the film is formed, so that optical performance or mechanical performance of the bonded film can be ensured.
Claims20
A method for bonding a film to a lens, wherein the method comprises:
- fastening the lens to a first jig;
- fastening the film to a second jig, wherein the second jig is a deformable flexible jig, and wherein a size of the film is equal to or less than an effective aperture of the lens;
- obtaining first boundary information of a first full aperture of the lens in order to align the lens with the first jig;
- obtaining second boundary information of a second full aperture of the film in order to align the film with the second jig;
- and
- moving the first jig and the second jig relative to each other in order to gradually bond from a middle position to an edge position on the lens to the film.
A device comprising:
- a memory configured to store instructions for bonding a film to a lens;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the device to:
- fasten the lens to a first jig;
- fasten the film to a second jig, wherein the second jig is a deformable flexible jig;
- obtain, using a first alignment camera, first boundary information of a first full aperture of the lens in order to align the lens with the first jig, wherein a first photographing range of the first alignment camera covers the first full aperture of the lens;
- obtain, using a second alignment camera, second boundary information of a second full aperture of the film in order to align the film with the second jig, wherein a second photographing range of the second alignment camera covers the second full aperture of the film;
- and
- move the first jig and the second jig relative to each other, to gradually bond a middle position to an edge position on the lens to the film.
A method for bonding a film to a lens, wherein the method comprises:
- fastening the lens to a first jig, wherein an effective aperture of the lens ranges from 1 millimeter (mm) to 60 mm, wherein when a film bonding surface of the lens is a convex surface, a first ratio of a curvature radius of the film bonding surface to a bonding aperture of the film bonding surface is greater than 1.2, and wherein when the film bonding surface is a concave surface, a second ratio of the curvature radius to the bonding aperture of the film bonding surface is greater than 1.5;
- fastening the film to a second jig, wherein the second jig is a deformable flexible jig;
- obtaining first boundary information of a first full aperture of the lens in order to align the lens with the first jig;
- obtaining second boundary information of a second full aperture of the film in order to align the film with the second jig;
- and
- moving the first jig and the second jig relative to each other in order to gradually bond from a middle position to an edge position on the lens to the film.
