Gripper for a contact lens and process for transporting a contact lens

摘要

A gripper (1) for a contact lens comprises a gripper head (2) having a bearing surface (21) for the contact lens (L) to adhere thereto. The gripper (1) further comprises an ejector (23) for mechanically displacing the contact lens, at least partially, away from the bearing surface (21). Also a process for transporting a contact lens (L) from a start location to a destination location, comprising the steps of providing the gripper (1) and positioning the gripper head (2) of the gripper at the start location with its bearing surface (21) adjacent to the contact lens (L) at a distance sufficiently close to the contact lens (L) to cause the contact lens to adhere to the bearing surface (21), moving the gripper (1) together with the contact lens (L) adhered to the bearing surface (21) to the destination location, and actuating the ejector (23, 24) in order to mechanically displace the contact lens (L) at least partially from the bearing surface (21) until the contact lens comes into sufficient contact with a receiving liquid at the destination location in order to release the contact lens (L) from the gripper (1).

1. A gripper (1) for a contact lens (L) comprising a gripper head (2) having a bearing surface (21) for the contact lens (L) to adhere thereto, and further comprising an ejector (23, 24) for mechanically displacing the contact lens (L), at least partially, away from the bearing surface (21); and wherein the ejector comprises a plurality of elector pins (23), the elector being actuatable such that the ejector pins (23) are movable from a rest position in which the ejector pins (23) do not interfere with the bearing surface (21), to an ejection position in which the ejector pins (23) axially protrude beyond the bearing surface (21), and vice versa.
