Patent ID: 6928332

Claim:
A system for processing a workpiece ( 5 ) located in a predefined process station ( 1 ) at a plurality of process sites ( 4 ) with programmed process parameters, comprising at least one process tool ( 7 ) for processing said workpiece ( 5 ) at said process sites ( 4 ) and a recognizing means ( 200 ) for identifying whether said process tool ( 7 ) is located in said process station ( 1 ), characterized in that said recognizing means ( 200 ) is designed to identify said location of said process tool ( 7 ) in said process station ( 1 ); to identify said location of said workpiece ( 5 ) in said process station ( 1 ); and to determine therefrom the location of said process tool ( 7 ) relative to each process site ( 4 ); whereby said process tool ( 7 ) is provided with at least one marking ( 202 ) and said recognizing means ( 200 ) comprises an imaging means ( 201 ) for imaging said process station ( 1 ) and at least a section of said workpiece ( 5 ), an image processing means ( 203 ) identifying the location of said process tool ( 7 ) relative to said workpiece ( 5 ) by processing an image of said at least one marking ( 202 ) and of said at least one section of said workpiece ( 5 ), and a means ( 7 ) for setting said tool ( 7 ) to said process parameters on the basis of the position of said process tool ( 7 ) relative to selected process site ( 4 ).
