Abstract
A method and apparatus are provided for batch, continuous, or semi-continuous coating of optical lenses. The method and apparatus use a plurality of carriages which are reciprocally moved in the apparatus to transfer jigs from a jig filled carriage to a lens loading arm and to load the jigs with lenses and then to transfer the jigs now containing uncoated lenses to a leading empty carriage. Using such a reciprocating motion, a leading empty carriage is now filled with jigs containing uncoated lenses and the uncoated lenses in the carriage may then be coated by dipping the carriage in a coating tank. After coating, the coated lenses are removed from the system. A similar reciprocating motion is used in the coated lens unloading section.
Claims4
An apparatus for coating optical lenses comprising:
- a filled jig carriage which contains jigs in a front-back and side-by-side configuration;
- an empty carriage;
- an uncoated lens loading station;
- an uncoated lens loading arm;
- an uncoated lens input means;
- a coating section;
- and
- wherein a leading empty carriage and preceding filled jig carriage are positioned in the uncoated lens loading section with the filled jig carriage adjacent the uncoated lens loading arm wherein the uncoated lens loading arm removes a single front side-by-side row of jigs from the filled jig carriage, lenses from the lens input means are secured in the jigs and the filled jig carriage moved back so that the empty carriage is adjacent the uncoated lens loading arm and the lens containing jigs transferred to the empty carriage, with the above steps being continued until the filled jig carriage is empty thereby resulting in a new empty carriage and the former empty carriage is now a filled jig and uncoated lens carriage which is moved out of the uncoated lens loading section and is dipped in the coating section.
