Apparatus for removing an ophthalmic lens from a mold half
View Patent ↗An apparatus ( 1;2 ) for removing an ophthalmic lens from a mold half ( 3;4 ), comprises a ring member ( 10;20 ) movable towards and away from the mold half ( 3;4 ), the ring member ( 10;20 ) comprising a central opening ( 103;203 ) and a plurality of nozzles ( 100;200 ) circumferentially distributed about the ring member ( 10;20 ), each nozzle ( 100;200 ) having an outlet opening directed towards the mold half ( 3,4 ) as the ring member ( 10;20 ) is placed on the mold half ( 3;4 ), and a gripper member ( 11;21 ) arranged to be movable towards and away from the mold half ( 3:4 ) through the central opening ( 103;203 ) of the ring member ( 10;20 ).
1. An apparatus configured to remove an ophthalmic lens from a mold half, comprising:
a ring member configured to be movable towards and away from the mold half, the ring member comprising a central opening and a plurality of nozzles circumferentially distributed about the ring member, each nozzle having an outlet opening directed towards the mold half as the ring member is placed on the mold half, and wherein the ring member further comprises a sealing member configured to provide a seal for the mold half preventing fluid from escaping as the ring member is placed on the mold half; and
a gripper member configured to be movable towards and away from the mold half through the central opening of the ring member.
2. The apparatus according to claim 1 , wherein the gripper member comprises an attachment surface which is provided with holes and a channel which is connected to and in fluid communication with the holes provided in the attachment surface configured to allow suction or overpressure to be applied for gripping or releasing the ophthalmic lens.
3. The apparatus according to claim 1 , wherein the ring member and the gripper member are made from a material which is resistant to corrosion, e.g. comprising stainless steel or plastic material.
