Device and method for deblocking optical workpieces, in particular spectacle lenses

摘要

The invention relates to a deblocking device and an associated method for deblocking optical workpieces, for example, eyeglass lenses. The deblocking device has a first moving apparatus for rotating a workpiece blocked on a block piece about a workpiece rotational axis, a nozzle assembly having a nozzle for discharging a high-pressure pressure medium jet in a direction substantially perpendicular to the workpiece rotational axis onto an edge area between the workpiece and block piece, and a second moving apparatus for generating a relative motion between the workpiece and the nozzle along the workpiece rotational axis.

主权项

1. A device for deblocking optical workpieces comprising:
a first movement device for rotating a workpiece, which is blocked on a block piece, about an axis of rotation of the workpiece; a nozzle subassembly with a nozzle for delivery of a high-pressure jet of pressure medium in a direction substantially transverse to the axis of rotation of the workpiece onto an edge region between workpiece and block piece; a second movement device for producing a relative movement between the workpiece and the nozzle along the axis of rotation of the workpiece; and one of the workpiece and the nozzle being displaceable with respect to another by the second movement device along the axis of rotation of the workpiece with positional regulation so that the high-pressure jet of pressure medium can be oriented to a predetermined place of incidence in the edge region between workpiece and block piece.
