AI Technical Summary

Problems solved by technology

Such machines are typically designed for large-scale optical fabrication laboratories, are expensive, and require auxiliary installation equipment
These large spin-coating machines are not practical for small-scale labs that may produce smaller quantities of lenses per day
There is currently no compact spin-coating machine that includes a single station capable of producing pre-cured lenses with two or more coating layers

Abstract

An improved spin coating system and a method of producing optical articles using a spin coating machine are provided herein. The system includes at least one distribution arm assembly. The holder assembly is movable along a substantially vertical axis. The dispensing arm assembly has a base and at least one arm having a first end and a second end and is movable along a horizontal axis. The at least one arm is operatively coupled to the base at the first end and to at least one applicator at the second end, and the applicator is operatively coupled along the said substantially vertical axis. The method includes: depositing a primer layer on a lens using the dispensing arm assembly; then depositing a hard coat; and drying and cooling the resulting coating using a drying / cooling station positioned substantially along the substantially vertical axis. the base material.

Description

technical field [0001] The present invention relates to an improved spin coating machine and spin coating method. Background technique [0002] A number of different methods are known for coating the surface of an optical article to provide one or more layers (eg, an impact-resistant layer, a scratch-resistant layer, an anti-smudge layer, or an anti-reflection layer) to the optical article. It is common practice in the art to apply several coatings to at least one major surface of a lens substrate, such as an ophthalmic lens or a lens blank, in order to impart additional or improved optical or mechanical properties to the finished lens. [0003] Spin coating is a method used to coat optical articles such as ophthalmic lenses. In the spin-coating method, a predetermined volume of coating solution is dispensed at the center of the article while spinning the article at a moderate speed, and then the article is spun at a very high speed so that the solution spreads over substan...
