Definitions

  • the invention relates to machines for coating an optical article such as an ophtalmic lens, and in particular spectacle lenses preferably mounted on a spectable frame, with an anti-soiling coating composition.
  • the invention further relates to a method for using such a machine.
  • lenses and in particular spectacle lenses, comprise an ophthalmic substrate having geometrical features adapted to the wearer.
  • the ophthalmic substrate requires the adding of coatings, for instance an anti-abrasive coating to increase the abrasion resistance of the lens, an anti-reflective coating to decrease the reflection of light and an anti-soiling coating applied over the anti-reflective coating.
  • the anti-soiling coating provides an outer coating that can be more resistant to contamination for instance by organic impurities and more easily cleaned than the anti-reflective coating.
  • the anti-soiling coating furthermore protects the anti-reflective coating.
  • the wearer of the lens can wish to replace such an anti-soiling coating because the effects of said coating can decrease over time.
  • Such a method is also known from the International patent application WO 2004/111691 in which an activation treatment of technical species at about atmospheric pressure is carried out, in particular a corona discharge treatment or a plasma treatment, for removing an initial outermost coating layer of a coated optical lens.
  • an activation treatment of technical species at about atmospheric pressure is carried out, in particular a corona discharge treatment or a plasma treatment, for removing an initial outermost coating layer of a coated optical lens.
  • a final coating in particular an anti-soiling coating, is deposited on the lens by vacuum, dip, spin, spray or stamping coating.
  • an anti-soiling coating is deposited on the lens by vacuum, dip, spin, spray or stamping coating.
  • the International patent application WO 2007/051841 describes a semi-finished lens substrate having a first coated layer referred to as an anti-reflective coating which is deposited by evaporation in a vacuum chamber and having a second coated layer referred to as an anti-soiling coating which is also deposited by evaporation in a vacuum chamber. It is necessary to carry out a pre-treatment before the depositing of the anti-soiling coating on the anti-reflective coating.
  • the pre-treatment is an energetic treatment required to activate the adherence properties of the anti-reflective coating.
  • the energetic treatment is a vacuum plasma treatment.
  • the anti-soiling coating is made from a liquid composition which also needs to be activated by vacuum plasma treatment.
  • the activation of the anti-reflective coating and the liquid composition can be made in the same vacuum chamber of a known vacuum treating machine provided with a pump.
  • the vacuum evaporation of the liquid composition is made via an evaporation device associated with the vacuum treating machine, the evaporation device comprising an elongated piece of steel wool connected on both sides to an electrical circuit.
  • the invention is directed to a machine for coating or recoating an optical article with an anti-soiling coating composition, which machine is simple to implement, compact and economic.
  • the invention accordingly provides a machine for coating an optical article with an anti-soiling coating composition, comprising:
  • control unit controlling the plasma generator for removing an initial outermost anti-soiling coating of the optical article
  • control unit controlling the evaporation device for recoating the optical article with the anti-soiling coating composition
  • control unit being further configured to causes the vacuum pump to suck gases from the vacuum chamber during vacuum plasma treatment;
  • control unit being further configured to causes the vacuum pump not to suck gases from the vacuum chamber during vacuum evaporation treatment.
  • the machine according to the invention is configured for recoating the optical article first by removing the initial outermost anti-soiling coating and next by depositing a new anti-soiling coating on the optical article.
  • the two distinct treatments are implemented in the same vacuum chamber of the machine so that the machine is simple and economic.
  • a vacuum pump is used to obtain the vacuum in the chamber.
  • the vacuum pump which is first connected (a flow connection causing the pump to suck) to the vacuum chamber is then disconnected (a flow interruption causing the pump not to suck) between the two treatments successively carried out so that the quality of the vacuum evaporation treatment is increased.
  • a vacuum plasma chamber is generally inconsistent with evaporation treatment due to the gas flow needed during the plasma treatment.
  • the invention assumes that it is actually possible to have a quiet state in the vacuum plasma chamber by causing the vacuum pump not to suck gases from the vacuum chamber.
  • the machine further comprises a data processing system which is configured to control both and successively the plasma generator and the evaporation device so that the machine is particularly simple both to make and to use.
