<p>A tool for gripping ophthalmic lenses having at least one vacuum gripper, a shaft associated with said vacuum gripper, the shaft having two ends and being slidably attached at one end thereof to a support structure, a resilient member which biases the vacuum gripper in a direction away from said support structure and a locking member which locks the shaft in a desired position during a lens gripping operation. Another embodiment of the present invention includes a lens hold down mechanism having a support member, at least one shaft slidably connected to said support member, a resilient member which biases said shaft in a downward direction, a lens contact member attached to said shaft and a robotic arm connected to said support member, wherein when said robot moves in a downward direction to pick up a lens tray, said lens contact member will contact lenses in said tray and cause said shaft to move upwardly with respect to said support member.</p> |
