Abstract
A compact automatic apparatus for rapidly curing photosensitive coatings on eyeglass lenses. A precision adjustable automatic programmer controls process cycling, ultraviolet intensity and radiation time. A control panel is used to switch the apparatus on or off and to manually select cycle parameters. The apparatus electronically monitors radiation intensity and uses a flashing light to warn the operator of low ultraviolet intensity. Apparatus components are cooled by a filtered force air convection system that prevents flow of unfiltered air into the apparatus. An automatically programmed linear motion lens transport carriage passes through an automatic outer door which allows inward and outward passage of the lens while protecting the operator from ultraviolet radiation. The outer door shields the machine interior from dirt and dust. After the outer door closes behind the entering lens, the lens transport carriage speed changes to a preselected irradiation cycle speed and an automatic shutter opens to allow the ultraviolet radiation to reach the lens. Ultraviolet radiation is supplied by a cylindrical ultraviolet lamp in the radiation chamber. At the proper time, the shutter clo…
