摘要:
An apparatus for the automated production of ophthalmic lenses, particularly compound lenses having a plastic coating on a plastic lens is described. A mold, after rotational orientation, is placed in a gimbal assembly to provide for the proper tilt. This gimbal assembly forms part of a fixture attached to an indexing means which moves for complete assembly of a molding fixture and then moves the molding fixture through a chamber to cure the resin. A preform, after rotational orientation, is held, by a preform gripper placed above the mold, and with sufficient clearance between the mold and the preform to allow the correct resin thickness during the curing portion of the process. The fixture is also provided with members to firmly grip the preform gripper so as to maintain its orientation throughout the curing process.
