Description

Dust removal device

technical field

The invention relates to a dust removal device, in particular to a dust removal device for removing dust on a lens.

Background technique

Before the lens is coated, it is usually necessary to remove the dust on the lens surface to ensure the cleanliness of the lens surface and improve the coating quality. At present, the way to remove dust on the lens is generally to place the lens on a carrier plate, then pick up the carrier plate with one hand, and hold the ion air gun to blow dust on the lens with the other hand. However, this method requires manual operation, which will destroy the dust-free environment of the lens. And it is also easy to make the blown dust fall on the lens again, affecting the effect of dust removal.

Contents of the invention

In view of this, it is necessary to provide a dust removal device that can effectively remove dust on the lens.

A dust removal device comprises a top cover, an accommodating cavity, a bracket, a slide rail, a dust removal sliding seat, an air extractor, an air blower and a lens carrier disc. The accommodating cavity has an opening. The top cover is used to seal the opening of the accommodating cavity to form an airtight accommodating space. Both ends of the bracket are respectively fixed in the accommodating cavity. At least one side of the bracket is provided with a slide rail parallel to the bracket. The lens carrier plate is fixed on the bracket for carrying the lens to be dust-removed. The air extractor and air blower are arranged outside the accommodating cavity. The dust removal slide is connected with the air extractor and the air blower respectively and slides along the slide rail to simultaneously blow and suck air to the lens tray fixed on the bracket, so as to blow the dust on the lens. Drop and suck away.

Compared with the prior art, the dust removal device provided by the present invention can absorb the dust blown off the lens in time by setting the dust removal slide seat in the sealed space that can blow and suck air on the lens at the same time, and prevent the dust from falling again. Affects the dust removal effect on the lens.
