Patent ID: 8330067

Claim:
A method for an optical inspection of workpieces, which are delivered from a loading device to a transport device that is driven by a drive unit and which are transported by the transport device to an inspection device, which performs the optical inspection, and further to a discharge device, which selectively extracts the inspected workpieces depending on a result of the inspection, wherein on the transport device a plurality of transparent receiving bodies are firmly mounted or rotatably supported, each of the receiving bodies comprising at least one recess, into which the workpieces are inserted individually or in groups; wherein each receiving body is exposed at an inspection position to inspection radiation, which is captured and analysed by the inspection device; wherein the receiving bodies are firmly mounted or rotatably supported on a receiving ring, above which a synchronization ring with intake funnels is mounted; and wherein the workpieces are cast by the loading device into the intake funnels and drop from the intake funnels each into the recess of the corresponding receiving body.
