Abstract
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.
