Definitions

  • the invention relates to a processing method for a spectacle lens blank, preferably made of plastic, in which a block piece for holding and supporting the lens blank is connected in a processing machine by means of a connecting compound with a first side of the lens blank, for this purpose between the block piece and the first side at least a cavity is delimited using a sealing or supporting means, wherein the sealing or supporting means has an inner diameter Dd, Ds and is preferably sealingly applied in the region of the inner diameter Dd, Ds against the first side, in the cavity, the compound compound is filled or in the compound is already provided compound compound and then cured.
  • the bonding compound does not necessarily have to be filled or poured.
  • the bonding compound is pre-portioned in a somewhat firmer form is applied to the block piece and then the lens blank is placed or pressed.
  • the lens blank is placed against the support means for the purpose of determining its relative position to the block piece and the compound compound is molded onto the lens blank or the first side.
  • the lens blank only then limits the cavity thus formed and already prefilled.
  • the cavity is only partially limited when using pre-portioned compound by the lens blank, the block piece and the support means. A sealing closure of the cavity is not necessary.
  • the support means has only three contact points for the lens blank.
  • the Eyeglass blank inserted over the molded by means of the compound mass block piece in a milling and / or lathe or grinder, wherein the lens blank is supported on the first side by the connecting mass over a diameter Dd, Ds corresponding diameter Dv.
  • Dd diameter
  • Ds diameter
  • Dv diameter
  • a block piece for spectacle lens blanks which has a coupling part and a holding part.
  • the holding part can be shaped to the shape of the lens blank.
  • the necessary holding power is by heating and pressing, if necessary with the addition of adhesive, achieved.
  • the associated with the pressing deformation of the lens blank is disadvantageous because they have a negative effect on the geometry of the lens or the lens at the latest after blocking.
  • the spectacle lens blank is supported by the bonding compound only in the area of the diameter which is under no circumstances machined. A further reduction of the diameter can be made only after the blocking of the block piece including the bonding mass.
  • US 1 952 373 A describes a processing method according to the preamble of claim 1 and a unit according to the preamble of claim 9.

Since a lens blank usually has a very irregular peripheral surface, remains as a sealing surface for applying the sealant for the purpose of limiting the cavity for the compound mass only the first side of the lens blank. In addition, since the prefabricated first page is a more precise reference surface.
  • an edge of the lens blank is machined and the diameter Dr is reduced to a diameter D1, wherein for the diameter D1 the dimension of the diameter Dv or a dimension which is at most 1 mm to 6 mm is larger, is provided.
  • the diameter D1 should be the measure of the diameter Dv of the bonding mass.
  • this processing step it is also possible to reduce both the lens blank and the bonding compound to a diameter smaller than D1 as set forth below.

  • the round shape of the lens blank or of the lens thus produced is generally independent of the shape of the lens to be produced Retain semi-finished, wherein the diameter Dr is reduced as described above to a level D1, which still ensures the production of the desired spectacle lens.
  • the round shape of the semi-finished product is usually maintained for two reasons.
  • the lens blank is not only reduced in diameter to a minimum during the cutting or chip process, but also receives an oval or polygonal shape deviating from the round shape. Also in this case, it is possible to support not only the round central part of the semifinished product by the bonding compound, but the whole first side of the lens blank or the semifinished product, regardless of the shape. The compound is processed with.
  • a protective layer is provided between the lens blank and the bonding compound.
  • the protective layer is usually applied in advance on the lens blank or is already provided on this, so that the prefabricated first page is not damaged.
  • the lens blank is so held indirectly over the protective layer of the bonding compound.
  • the connecting compound is introduced into the cavity via a plurality of filler neck or via a plurality of outlet openings of one or more filler neck.
  • the filler neck or the outlet openings have different directional components, so that the bonding compound is not only introduced at different positions of the respective filler neck, but is also introduced within a position of a filler neck in different directions or with different directional components.
  • the various positions of the filler neck also different directional shares go for the compound mass to be introduced.
  • the filling level of the bonding compound within the cavity is monitored by means of a laser distance sensor.
