Membrane attaching method of lens

Abstract

The invention provides a lens film laminating method and lens film laminating equipment. The first jig and the second jig are controlled to move relatively, so that the lens is gradually attached to the membrane from the middle position to the edge position, bubbles between the membrane and the lens can be reduced, and a good membrane attaching effect is achieved. Moreover, the film does not need to be processed in advance, and the lens does not need to be obtained through injection molding after the film is formed, so that the optical performance or mechanical performance of the laminated film can be ensured, and the required optical element can be obtained through a simple film laminating method. And the optical performance and the mechanical performance of an optical element obtained after the lens is attached to the diaphragm can be ensured.

Description

technical field [0001] The present application relates to the technical field of film material lamination, and in particular, to a method for laminating a film of a lens. Background technique [0002] In the field of optical imaging, it is often necessary to stick the film on the optical lens to improve the imaging effect of the optical lens. In order to obtain a flat film effect, at present, the main method of filming on the lens is: attaching a flat film to the surface of the sheet substrate, and then thermally bending the whole composed of the film and the substrate, and then bending the sheet. Put it in the injection fixture, and after injection molding the optical material, the optical element with the same optical properties as the diaphragm can be obtained. However, after the film is thermally bent, due to its own characteristics, it is very easy to stretch and cannot maintain the initial pre-bent shape, thereby affecting the surface shape accuracy of the final optic...

AI Technical Summary

Problems solved by technology

However, after the diaphragm is hot-bent, due to its own characteristics, it is extremely easy to stretch and cannot maintain the initial pre-bent shape, thus affecting the surface accuracy of the final optical element

Moreover, since the temperature of the injected optical material is generally relatively high, it is easy to affect the optical or mechanical properties of the film
