Definitions

  • the invention relates to a device for processing spectacle lenses with at least one processing station for processing the edge and / or a surface of the spectacle lens and a multi-axis positioning unit, with a gripper unit that grips the spectacle lens and into the respective processing station uses or removes from this.
  • Eyeglass lenses are currently manufactured as follows:
  • the invention is based on the object of developing a device for processing spectacle lenses with at least one processing station for processing the edge and / or a surface of the spectacle lens in such a way that simple handling of a spectacle lens and in particular the insertion of this spectacle lens into a riming lens and / or surface processing device is possible.
  • the invention is based on the basic idea of handling glasses with suction cups.
  • Suction pads are generally known for handling objects, but have not been taken into consideration for the handling of spectacle lenses. The reason for this may be that there is a general prejudice that suction cups can only be applied to flat surfaces and not to convex or concave surfaces, as is usually the case with spectacle lenses.
  • the gripper unit designed according to the invention has a plurality, comparatively small suction pads. Even with the progressive surface of a progressive spectacle lens, it can then be assumed that the surface is approximately rotationally symmetrical over the area to which the respective suction gripper is engaging, so that the so-called "bell" of the suction gripper lies completely against the surface.
  • the gripper unit has two “groups” of suction grippers, which are arranged along a straight or curved line.
  • the two groups of suction pads can be arranged along the two sides of a "U".
  • the gripper unit designed according to the invention can, for example, on the concave side of the spectacle lens when automating a known guiding device are placed, a so-called block for holding the spectacle lens in the edging device being placed on the convex side in a known manner.
  • the gripper unit designed according to the invention thus allows, for example, the picking up of a spectacle lens to be edged from a centering unit in which the block has been placed, without an operator having to monitor the insertion process of the spectacle lens into the processing station.
  • FIG. 1 is a plan view of an embodiment of a suction gripper unit designed according to the invention
  • FIG. 2 shows a side view of a further exemplary embodiment.
  • FIG. 1 shows a suction gripper unit according to the invention, which is used for inserting an eyeglass lens into a device (not shown) for processing eyeglass lenses.
  • This device has at least one processing station for processing the edge and / or a surface of the spectacle lens and a multi-axis positioning unit to which the suction gripper unit is attached.
  • the positioning unit serves to position the suction gripper unit relative to the processing station or to insert or remove the suction gripper unit in or out of the processing station.
  • the suction gripper unit has a plurality of suction grippers 1 to 6, the diameter of each of which is significantly smaller than the typical diameter of a spectacle lens.
  • the typical diameter of a lens is between 60 and 80 mm.
  • the suction pads provided according to the invention have preferably has a diameter which is at least a factor of 3 below the diameter of the lens.
  • the diameter of the so-called suction cup of the suction pads is particularly preferably approximately 5 to 15 mm.
  • the individual suction pads 1 to 6 of the suction pad unit are arranged in the form of a "U".
  • two suction cups are connected in terms of flow in such a way that a control unit (not shown) pressurizes or ventilates them together.
  • the suction pads 1 and 4, 2 and 6, 3 and 5 are each connected to one another in terms of flow. It is thus possible to adapt the gripper unit designed according to the invention to individual, extremely designed spectacle lens shapes by switching off individual suction gripper pairs in such a way that the spectacle lenses can be securely picked up and handled.
  • FIG. 2 shows a further exemplary embodiment of the invention.
  • this exemplary embodiment there are two coulters 11 and 12 of suction grippers, of which the coulter 11 is attached to an arm 11 'and the coulter 12 to an arm 12', which can be pivoted about a common pivot point 13.
  • the two arms are biased against each other by springs.
  • This design makes it possible for some of the suction pads to be retractable counter to the direction of attachment, which is symbolized by an arrow 14.
  • the suction gripper unit according to the invention has the advantage, among other things, that the spectacle lens can be easily converted from the horizontal to the vertical position and vice versa after being taken up.
  • the gripper unit can also be adapted to extremely shaped spectacle lenses.
  • Suction cup shapes can be used as suction cups, as are known from the prior art for suction cups for handling boxes, etc. A detailed description of the suction grippers can thus be dispensed with at this point.
  • the control unit which pressurizes or ventilates the individual suction pads or the suction pads combined in pairs can also be designed according to the state of the art, so that a detailed description can also be dispensed with.
  • the device designed according to the invention for processing spectacle lenses with at least one processing station for processing the edge and / or a surface of the spectacle lens and a multi-axis positioning unit makes it possible to easily accommodate an eyeglass lens during the machining process, to handle and insert into a machining station or remove from it.

Abstract

Un dispositif de façonnage de verres de lunettes comprend au moins une station de façonnage du bord et/ou d'une surface du verre de lunettes et une unité de positionnement à axes multiples, comprenant un organe de préhension qui saisit le verre de lunettes et l'introduit dans la station de façonnage ou l'enlève de celle-ci. Le dispositif se caractérise en ce que l'organe de préhension comprend au moins une pince aspirante qui est ventilée ou dans laquelle une dépression est générée par une unité de commande.
