Abstract
A manufacturing apparatus and a manufacturing method for a molded lens are provided. A substrate is located between a first molding core and a second molding core, and the first molding core is moved so that the substrate is formed into a lens. A distance sensor sends a plurality of press distance parameters of moving the first molding core, and the press distance parameters may form a press curve. The press curve and a reference press curve is compared for a difference by a processor and a comparator. The processor determines whether the difference is within an error range.
Claims19
A manufacturing method for a molded lens, comprising:
- locating a substrate between a first molding core and a second molding core;
- moving the first molding core so that the substrate is formed into a lens;
- sending a plurality of press distance parameters of moving the first molding core by a distance sensor, wherein the press distance parameters form a press curve;
- comparing the press curve and a reference press curve for a difference by using a processor and a comparator;
- determining whether the difference is within an error range by the processor and wherein when the difference exceeds the error range, an alarm sends a warning signal.
