Method for manufacturing a lens

Abstract

This invention provides a method for manufacturing a lens. The method includes forming a lens between a first mold core and a second mold core; separating the first mold core and the second mold core, allowing the lens to attach to the first mold core; performing a dry heating process on the first mold core and the lens; performing a dry cooling process on the heated first mold core and the lens; and separating the lens from the first mold core. This invention provides a lens manufacturing method that can improve production efficiency.

Claims

1. A method for manufacturing a lens, comprising: A lens is formed between a first mold core and a second mold core in a mold; Separate the first mold core and the second mold core, and attach the lens to the first mold core; perform a dry heating process on the first mold core and the lens; perform a dry cooling process on the heated first mold core and the lens; and separate the lens from the first mold core.

2. The method of manufacturing a lens as claimed in claim 1, wherein the first mold core is a concave mold core and has a curved surface, and the lens is attached to the curved surface.

3. A method for manufacturing a lens as claimed in claim 1, wherein the material of the lens includes at least one of a silicate monomer and a silicate polymer.

4. The method of manufacturing a lens as claimed in claim 1, wherein in the dry heating process, the heating temperature is between 80 degrees Celsius and 120 degrees Celsius.

5. The method of manufacturing a lens as claimed in claim 1, wherein the heating method of the dry heating process includes at least one of hot air convection and heat conduction.

6. The method for manufacturing a lens as described in claim 1, wherein the heating time in the dry heating process is more than 10 minutes and less than 30 minutes.

7. The method of manufacturing a lens as claimed in claim 1, wherein in the dry cooling process, the cooling temperature is between 0 degrees Celsius and 15 degrees Celsius.

8. The method of manufacturing a lens as claimed in claim 7, wherein in the dry cooling process, the temperature of the first mold core is reduced to between 0 and 15 degrees Celsius within 30 seconds.

9. The method of manufacturing a lens as claimed in claim 1, wherein the cooling method of the dry cooling process includes at least one of cold air convection and heat conduction.

10. The method of manufacturing a lens as claimed in claim 9, wherein the cold air convection further comprises blowing solid carbon dioxide.

11. A method for manufacturing a lens as claimed in claim 1, wherein the step of separating the lens from the first mold core includes: A demolding device is used to deform the first mold core, so that the lens and the first mold core can be separated.
