MACHINE FOR COATING AN OPTICAL ARTICLE WITH A PREDETERMINED COATING COMPOSITION AND METHOD FOR USING THE MACHINE

摘要

The machine for coating an optical article with a predetermined coating composition, includes a vacuum chamber (8) having an interior space (31) configured to receive the optical article, a vacuum pump (20) connected to the vacuum chamber (8), a nebulizer (40) configured to carry out a vacuum nebulization treatment of the composition for depositing it on the optical article in the vacuum chamber, and a control unit (2) configured to control the vacuum pump; the control unit being configured to cause the vacuum pump to suck gases from the vacuum chamber to bring it to a predetermined required pressure for the vacuum nebulization treatment, and the control unit and the nebulizer are configured to nebulize the predetermined coating composition which is liquid into a mist of aerosol droplets and to direct the droplets towards at least a surface of the optical article.

主权项

1. Machine for coating an optical article (28) with a predetermined coating composition, comprising:
a vacuum chamber (8) having an interior space (31) configured to receive said optical article (28); a vacuum pump (20) connected to said vacuum chamber (8); a nebulizer (40) configured to carry out a vacuum nebulization treatment of said predetermined coating composition for depositing it on said optical article (28) in said vacuum chamber (8); and a control unit (2) configured to control said vacuum pump (20); said control unit (2) being further configured to cause the vacuum pump (20) to suck gases from said vacuum chamber (8) to bring said vacuum chamber (8) to a predetermined required pressure for said vacuum nebulization treatment; and said control unit (2) and said nebulizer (40) being further configured to nebulize said predetermined coating composition which is liquid into a mist of aerosol droplets and to direct said droplets towards at least a surface (35, 36) of said optical article (28).
