Manufacturing apparatus and method for molded lens

A manufacturing apparatus for a molded lens, wherein the manufacturing apparatus performs a pressing process on a substrate, and the manufacturing apparatus comprises:

• a molding chamber, wherein a first molding core or a second molding core is movable in the molding chamber, and the substrate is located between the first molding core and the second molding core;
• a distance sensor, close to the molding chamber;
• a processor, coupled to the distance sensor;
• an pneumatic cylinder, coupled to the processor and capable of moving the first molding core or the second molding core;
• a pressure adjusting valve, coupled to the processor and the pneumatic cylinder and capable of adjusting a pressure of the pneumatic cylinder;
• a pressure gauge, coupled to the processor and the pneumatic cylinder and capable of displaying the pressure of the pneumatic cylinder;
• a heater, coupled to the processor and capable of heating the molding chamber;
• a power meter, coupled to the processor and the pneumatic cylinder and capable of measuring power of the heater;
• a temperature controller, coupled to the processor and the heater and capable of controlling a temperature of the heater;
• a comparator, coupled to the processor, wherein the distance sensor sends a plurality of press distance parameters of the pressing process, the press distance parameters form a press curve, and the processor and the comparator compare the press curve and a reference press curve for a difference;
• and
• a storage device, wherein data of the reference press curve is stored in the storage device.
