An apparatus and a method for deblocking a lens, wherein the lens is blocked with a block material on a block piece. The block material is preheated by radiation. The blocked lens, the deblocked lens, and the deblocked block piece are handled by means of separate grippers. For deblocking, the lens and the block piece are held by opposing holding devices in a rotating manner, while a fluid jet acts on the block material from the side. After the deblocking, the lens and the block piece are cleaned simultaneously. Then, a holding device together with the deblocked lens pivot out from a working space. The deblocked lens is placed with the block side upward in a transport carrier. This makes possible a simple design and an optimized process sequence.
Device (1) for deblocking a lens (2) from a block piece (3), on which the lens (2) is blocked by means of a block material (4), whereby a block side (2A) of the lens (2) is optimally provided with a protective layer (5),
Device according to one of the preceding claims, characterized in that the two holding systems (8, 9) can be moved away from one another axially, in particular here by the deblocked lens (2) being able to be moved in the area of a fluid jet (F3) for removing the protective layer (5) and/or from block material (4) from the block side (2A) of the lens (2).
Device (1) for deblocking a lens (2) from a block piece (3), on which the lens (2) is blocked by means of a block material (4), in particular according to one of the preceding claims, with a working space (6),
Device according to one of the preceding claims, characterized in that the first holding system (8) has a holder (8A) for rotating holding of the lens (2), whereby the holder (8A) can be displaced or moved away relatively from the block piece (3) in particular in a linear manner.
Device according to one of the preceding claims, characterized in that the first nozzle system (10) is designed for dispensing the fluid jet (F1) laterally to the block material (4), while the lens (2) rotates together with the block piece (3).
Device according to one of the preceding claims, characterized in that the device (1) has an onward-conveying system (20), in particular an additional conveyor belt, for conveying by other in particular smaller—transport carriers (18) for receiving deblocked lenses (2).
Device according to one of the preceding claims, characterized in that the device (1) has a testing system (25) for in particular optical testing of a blocked and/or deblocked lens (2).
Device according to one of the preceding claims, characterized in that the device (1) has a sorting system (23) for deblocked block pieces (3).
Method for deblocking a lens (2) from a block piece (3), on which the lens (2) is blocked by means of a block material (4), whereby a block side (2A) of the lens (2) is provided with an optional protective layer (5), whereby a lens (2) is deblocked preferably by means of a first fluid jet (F1) from a block piece (3), in particular while rotating,
