    摘要： A computer control system for optimizing process parameters in an automated production line for producing contact lenses. The system comprises a plurality of process controllers for controlling one or more process stations of the production line, each of the controllers regulating a plurality of process control devices that each control specific production parameters used in the automated manufacture of contact lenses at the process station(s). An automated lens inspection device automatically evaluates each contact lens produced and generates inspection data for each contact lens, and a polling device polls each of the process controllers on a frequent basis to acquire process control data for each period. Further included is a correlating device for correlating the inspection data to the process control data and the contact lens data to optimize process parameters used in the production of contact lenses. A relational database is also provided for storing the process control data, the contact lens data and the inspection data received from the correlating device.

    摘要： A production line tracking and quality control system and method thereof comprises a series of pallets for carrying one or more first contact lens mold halves or one or more complementary second contact lens mold halves throughout a contact lens fabrication facility. Each pallet of the series is transported on a conveyor device throughout the fabrication facility, and each pallet includes a unique identifying code. The fabrication facility includes one or more process stations and a control device provides real time monitoring of contact lens fabrication processes at the one or more process stations. The control device further includes a tracking device for identifying the unique code of each of the pallets at one or more process stations while continually receiving monitored process condition values at each station. For each identified pallet, the control device generates process status information for memory storage in the form of a reject flag, when the process conditions are out of predetermined limits, or, an acceptance flag indicating that process conditions are within predetermined limits. The process status information is updated when the pallets are identified and the status of each pallet is checked when entering or exiting a process station.

    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.

    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： Designs for basecurves are disclosed which are designed to promote adhesion of an excess polymer HEMA ring to the basecurve during a demolding operation such that the excess polymer HEMA ring is removed along with the basecurve during the demolding operation. The basecurve mold designs promote and maintain adhesion of an excess polymer HEMA ring to the basecurve in a process for molding cast contact lenses in mold assemblies, each comprising a frontcurve and a spaced basecurve, and wherein a molded lens is formed therebetween. In an embodiment of the invention, the annular area of the basecurve mold can be formed with an annular step which includes projecting teeth positioned therearound which project into the excess polymer HEMA ring.

    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, preferably a carbon dioxide (CO.sub.2) laser of about 80 Watts at a wavelength of 10.6 .mu.m, is applied to at least one of the mold portions. The exposure of the mold portion to the laser is between one half and one second. 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.
