Description

Technical Field

[0001] This utility model relates to the field of optical lens coating technology, and in particular to a vacuum coating uniform spraying device for photochromic materials of optical lenses. Background Technology

[0002] Coated lenses are lenses with a certain thickness and number of optical thin films on their surface, giving them optical, chemical, and mechanical properties that the lenses themselves do not possess. Lens coating solves the problem of taking photos in strong light while wearing glasses, and also prevents the lenses from appearing hazy in dim environments, indirectly relieving eye strain. Coated lenses have a significant vision-enhancing effect, preventing glare from strong light and making vision clearer and more comfortable. They are suitable for drivers to wear for long periods of driving without causing eye fatigue, and are also suitable for workers in smelting furnaces and kilns, as well as those working with television screens and computer terminals. They also enhance the aesthetics of the lens.

[0003] The initial coating methods included simple dip coating and brush coating. These methods were easy to operate but difficult to control the uniformity and thickness of the film. With the development of technology, coating spraying machines replaced the original coating methods. Spraying machines can apply coating materials to the surface of lenses, simplifying the operation steps for workers.

[0004] However, existing coating spraying machines typically fix the lens before transporting it to the spraying box for spraying. However, after fixing the lens, the spraying effect is better on the side of the lens facing the nozzle, but the spraying effect on the side of the lens away from the nozzle often fails to meet expectations. This results in poor uniformity of the overall film layer after lens coating, which may require rework to make the lens meet the standards for use. Based on this, this application proposes a vacuum coating uniform spraying device for photochromic materials of optical lenses, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum coating uniform spraying device for photochromic materials of optical lenses.
