Adhesive film device for dustproof antibacterial layer of lens

Abstract

The invention discloses an adhesive film device for a dustproof antibacterial layer of a lens. The adhesive film device comprises an adhesive film box, and a loading and unloading assembly; the loading and unloading assembly is arranged on the outer side of the adhesive film box; coating assemblies are arranged in the adhesive film box; the coating assembly is rotatably connected with the loading and unloading assembly; and the coating assemblies are used for coating the inner surface and the outer surface of the lens at the same time. The loading and unloading assembly places the lens on the coating assemblies or takes the lens down from the coating assemblies, and conveying assemblies in the coating assemblies drive the lens to rotate, so that the lens continuously passes through the spraying assemblies; multiple sets of spraying assemblies are arranged to spray the inner surface and the outer surface of the lens, and multiple layers of films are formed on the inner surface and the outer surface of the lens; the conveying assemblies rotate continuously; and lenses with multiple layers of films are produced continuously, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lens coating, in particular to an adhesive film device for an anti-dust and antibacterial layer of a lens. Background technique [0002] Glasses such as myopia glasses, presbyopic glasses, and sunglasses are glasses that people often use. With more and more types of glasses and an increase in the frequency of use, users have higher and higher requirements for glasses and lenses. With regard to the existing lenses, although they have strong anti-abrasion properties, and their anti-fouling properties are gradually improving, their antibacterial properties are still poor. [0003] Traditional lenses not only have a single function, but also do not have antibacterial performance, dustproof performance and radiation protection effect. Traditional lenses are not conducive to eye protection. [0004] For example, myopia glasses, as people's long-term wearables, especially for people with myopia, will wear myopi...

AI Technical Summary

Problems solved by technology

As far as the existing lenses are concerned, although they have strong anti-wear properties, and their anti-fouling properties are gradually improving, their antibacterial properties are still poor.

[0003] Traditional lenses not only have a single function, but also do not have antibacterial performance, dustproof performance and radiation protection effect. Traditional lenses are not conducive to eye protection.

[0004] For example, myopia glasses, as people's long-term wearables, especially for people with myopia, will wear myopia glasses for the rest of the time except for rest time. When people wear glasses for a long time, it is impossible to wear them frequently. The glasses are removed for cleaning, which makes it rare for myopia to be cleaned regularly

The surface of the lens that is not cleaned for a long time is easy to cause bacteria to grow. Bacteria in the air adhere to the surface of the lens and even form small colonies. cause health hazard

[0005] By spraying oxide materials to form an antibacterial, dustproof, anti-electromagnetic wave and anti-abrasion film on the surface of the lens, so that the lens has antibacterial, dust-proof, anti-electromagnetic wave and anti-abrasion properties, but the existing coating device cannot be used for coating. The thickness and spraying range are precisely controlled, and the lens coating can only be completed in a box with a certain space, which makes the production efficiency of coated lenses low
