Bernoulli gripper for intraocular and contact lenses
A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.
METHOD AND APPARATUS FOR CALIBRATING OPHTHALMIC LENS GRIPPERS
A method for calibrating lens grippers prior to use of the grippers in a lens manufacturing line includes providing a remote gripper calibration tool having an assembly plate and a Z-directional position sensor; providing a master gripper having a length dimension terminating in a tip, the length dimension being predetermined to match a desired final extension length of a lens gripper; mounting the master gripper to the assembly plate; measuring the Z-directional position of the tip of the master gripper with the Z-directional position sensor; unmounting the master gripper from the assembly plate; mounting a lens gripper to be calibrated to the assembly plate, the lens gripper having a tip, and calibrating the lens gripper by adjusting the final extension length of the tip of the lens gripper to a predetermined position relative to the measured Z-directional position of the tip of the master gripper.

In addition, based on the user's selection of the lens casing options, associate the selected frame and the selected lens casing with a customer order.
CLEANER FOR CLEANING GRIPPERS FOR OPHTHALMIC LENSES
A cleaner for cleaning grippers for the transport of ophthalmic lenses comprises: an exhaust air box comprising at least one inlet opening for allowing ambient air as well as lenses, lens parts, debris and fluid adhered to the grippers to be sucked into an interior of the exhaust air box, an outlet opening in fluid communication with the interior of the exhaust air box and a cleaner head arranged on the exhaust air box and comprising a plurality of receiver sleeves for receiving the grippers to be cleaned, a plurality of shutters, wherein each individual shutter of the plurality of shutters is arranged to open or close the fluid communication of at least one receiver sleeve (5) of the plurality of receiver sleeves (5) and the interior of the exhaust air box (1).
Methods and devices for moving wet ophthalmic lenses during their manufacture
Methods, devices, and systems for moving wet ophthalmic lenses are described in which the ophthalmic lenses are first placed in wells of lens carriers and are centered by the structure of the wells. The carriers are then moved to a transfer module of a packaging system for transferring the ophthalmic lenses in blister packages. The transfer from the carriers to the blister packages are performed by a pick and place robot having pickup heads sized and configured for suctioning the ophthalmic lenses from the lens carriers.
Gripper for an ophthalmic lens and process for transporting an ophthalmic lens
A gripper (1) for an ophthalmic lens comprises a gripper head (14) having a bearing surface (140), the bearing surface (140) having at least one through-opening (14), the bearing surface (140) further having a separate detection through-opening (142) other than the at least one through-opening (141); a suction channel (170) arranged in an interior of the gripper, the suction channel (170) leading to the at least one through-opening (141) in the bearing surface (140); an overpressure channel (130) arranged in the interior of the gripper, the overpressure channel (130) leading to the at least one through-opening (141); and a detection vacuum tube (16) arranged in the interior of the gripper, the detection vacuum tube (16) leading to the separate detection through-opening (142) in the bearing surface (140). The detection vacuum tube (16) has a distal end which is arranged in the detection through-opening (142) in a fluid-tight manner, and the detection through-opening (142) is arranged in the center of the bearing surface (140) of the gripper.
APPARATUS, SYSTEM AND METHOD FOR THE REMOVAL OF AN OPHTHALMIC LENS FROM A LENS TREATMENT CONTAINER
An apparatus for removal of an ophthalmic lens, such as a contact lens, for example a soft contact lens, from a lens treatment container for the accommodation of the ophthalmic lens during a lens treatment process, comprises: an exhaust air box comprising at least one inlet for allowing ambient air to be drawn into the exhaust box; an outlet in fluid communication with the exhaust air box, the outlet capable of being connected to a source of negative pressure; at least one tube having a proximal end connected to the at least one inlet of the exhaust air box, and a distal end having a displaceable nozzle; and an actuator connected to the nozzle, for displacing the nozzle from a standby position to a lens removal position, and back to the standby position.

BERNOULLI GRIPPER FOR INTRAOCULAR AND CONTACT LENSES
A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.
