Abstract

The present invention wraps the adhesive tape on the outer peripheral surface of the input mold, then injects the monomer solution into the mold cavity formed between them, and uses the visual recognition system to photograph the change of the liquid level of the monomer solution injected into the mold cavity so that Use the visual recognition system to accurately control the injection amount of the monomer solution, and compare the photographed liquid level change with the liquid level change shape of the monomer solution stored in advance. When the shape of the stored monomer liquid level is consistent, the controller can adjust the injection volume of the injector according to each stage, and inject the monomer solution into the mold cavity.

Description

technical field [0001] The present invention relates to a method and an apparatus for manufacturing an optical material by injecting a monomer solution into a cavity formed between a pair of molds whose outer peripheries are sealed. The invention relates to an automatic mold injection method and an automatic injection device for monomers for optical materials that can accurately control the amount of injection as the liquid level changes. Background technique [0002] Among optical materials, plastic lenses are lighter than glass lenses, are not easily broken, and have excellent processability. Recently there has been a trend of using more plastic lenses than glass lenses. The plastic lens is produced by injecting a high molecular compound called a monomer (monomer) into a mold for solidification, and then undergoing appropriate post-processing. That is, it is produced by injecting a monomer solution into a mold having an empty injection space (cavity) in the shape of a le...
