    摘要: An apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation is applied to at least one of the mold portions in a predetermined scanning pattern through the intermediary of galvanometer-driven mirrors. Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force breaks the polymerized lens/polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions separate. The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.

    摘要: Apparatus for removing and transporting ophthalmic lens mold sections from a mold, and generally comprising first, second, and third assemblies. The first assembly removes the lens mold sections from the mold and transports the lens mold sections to a first location, the second assembly receives the lens mold sections from the first assembly and transports the lens mold sections to a second location, and the third assembly receives the lens mold sections from the second assembly and transports the lens mold sections to a third location. Preferably, the first assembly includes a hand to receive the lens mold sections from the mold and to releasably hold the lens mold sections, and a support subassembly connected to the hand to support the hand and to move the hand between the mold and the first location. The second assembly preferably includes a support frame, a platform to receive the lens mold sections from the first assembly and supported by the support frame for movement between the first and second locations, and moving apparatus for moving the platform along the support frame and between these first and second locations. The preferred design of the third assembly includes a transport subassembly and a support column. The transport subassembly receives the lens mold sections from the second assembly, releasably holds those lens mold sections, and carries the lens mold sections to the third location; and the support column supports the transport subassembly for movement between the second and third locations.
