ABSTRACT:
An ophthalmic lens pallet having wells for receiving one or more lens containers at the receiving point achieves the requisite uniformity of motion in the direction of motion, and stability when transporting the lens in the orthogonal, non-translating directions by restraining the pallet between rails. A spring-loaded roller ball located on the side walls of the pallet body cooperate with guide rails on the conveyor to compress the spring-loaded roller ball when the pallet is between the guide rails. Blind holes on the pallet engage a drive which transports the pallet from the lens receiving point to an inspection station then to a lens disposition mechanism. The pallet wells comprise holes that pass through the pallet. These holes along with the rail and transport system make possible an arrangement of a lamp and camera for capturing an image of a lens.
