Embodiment Construction

[0064] figure 1 A recoating machine 1 is shown for recoating an optical article 28 , here formed from an eyeglass lens mounted on an eyeglass frame.

[0065] The machine 1 comprises a vacuum chamber 8 , a plasma generator 11 , an evaporation device 10 , an inlet circuit 12 , an outlet circuit 15 , a vacuum pump 20 and a control unit 2 .

[0066] The vacuum chamber 8 includes an inner space 31 configured to receive an eyeglass lens 28 mounted on an eyeglass frame.

[0067] The vacuum chamber 8 also includes a door 9 which is removable (see figure 2 and 3 description of).

[0068] The plasma generator 11 is directly connected to the vacuum chamber 8 .

[0069] The plasma generator 11 generally comprises a high frequency generator.

[0070] The evaporation device 10 is placed in the vacuum chamber 8 (ie, installed on the door 9 of the vacuum chamber 8) (see below).

[0071] The vacuum chamber 8 also includes a first inlet port 14 and a second inlet port 34 , both connected...

Abstract

The invention provides a machine and method for coating an optical article with an anti- soiling coating composition, comprising a vacuum chamber (8) configured to receive the optical article, a vacuum pump (20) connected to the vacuum chamber (8), a plasma generator (11) configured to carry out a vacuum plasma treatment of the optical article, an evaporation device (10) configured to carry out avacuum evaporation treatment of the composition for depositing it on the optical article, a control unit (2) controlling the plasma generator for removing an initial outermost anti-soiling coating ofthe article, controlling the evaporation device for recoating the article with the anti-soiling coating composition, being configured to causes the vacuum pump (20) to suck gases from the chamber (8)during vacuum plasma treatment and being further configured to causes the vacuum pump (20) not to suck gases from the chamber (8) during vacuum evaporation treatment.

Description

[0001] This application has an international application date of July 16, 2012, an international application number of PCT / IB2012 / 053624, a date of entering the Chinese national phase on January 17, 2014, a national application number of 201280035418.5, and an invention title of "Used to use A divisional application of an invention patent application for a machine for coating optical articles with an antifouling coating composition and a method for using the same. technical field [0002] The present invention relates to a machine for coating optical articles, such as spectacles, and in particular, spectacle lenses, preferably mounted on spectacle frames, with an anti-smudge coating composition. [0003] The invention also relates to a method of using such a machine. Background technique [0004] It is well known that lenses (and spectacle lenses in particular) include an ophthalmic substrate having geometrical features adapted to the wearer. [0005] Ophthalmic substrates ...
