  • Patent number: 11623371
    Abstract: A UV (ultraviolet) curing apparatus for a contact-lens polymerization process is provided. A UV curing module is equipped for the mold cavities of contact-lens curing molds, including a plurality of first UV light sources arranged above the mold cavities and a plurality of second UV light sources arranged below the mold cavities. A plurality of light output areas of a first light guide device guides the light beams emitted by the first UV light sources to illuminate upper light receiving surfaces of the molds. A plurality of reflecting plates of a second light guide device reflects and scatters the light beams emitted by the second UV light sources to lower light receiving surfaces of the molds. Thereby, the contact-lens polymer inside the molds is uniformly cured, and the yield is raised.

  • Patent number: 11566965
    Abstract: A contact lens retrieving method is applied to a contact lens, which is placed in a detection container containing a buffer solution and has been inspected in an optical detection. The method comprises steps: moving a vacuum sucker into the buffer solution at a first speed to make the contact lens depart from the lateral side of the detection container; moving the vacuum sucker away from a bottom of the detection container at a second speed with the vacuum sucker not leaving the buffer solution to make the contact lens flow toward a center of the detection container; moving the vacuum sucker to approach the contact lens at a third speed to make the vacuum sucker and the contact lens positioned to each other; and using the vacuum sucker to take up the contact lens and carry the contact lens out of the detection container.
