RECEIVING ASSEMBLY COMPONENT RECOGNITION STRUCTURE, AND ASSEMBLY INFORMATION RECOGNITION APPARATUS AND ASSEMBLY PROCESSING APPARATUS THAT USE THE STRUCTURE

摘要

A structure for recognizing a receiving assembly component, comprising:a recognition reference plane that is provided in a portion of an assembly base on a predetermined area of which there is placed a receiving assembly component used for assembling an assembly component and that serves as a reference used for recognizing layout information about a position and an attitude of the assembly base; anda recognition indicator element that is provided on the recognition reference plane so that an imaging tool performs imaging operation and that has, at a predetermined positional relationship, four unit pattern marks or more formed such that a density pattern of each of the unit pattern marks sequentially changes from a center position to a periphery of the mark.
