ABSTRACT:
An automatic assembly system wherein parts supplied from a feeder are held by a holder and are automatically mounted onto predetermined positions of a circuit board; comprising a first image pickup device which images at least a portion of said circuit board, a second image pickup device which images at least a portion of the part held by the holder means, a signal processor which processes an output of said first image pickup device to detect a deviation of said circuit board from a reference position and which also processes an output of said second image pickup device to detect a magnitude of deviation between said part and the predetermined position of said circuit board, and a positioning device which operates under control of said signal processor so as to adjust said predetermined position of said circuit board to a position opposing to said part and also to move said part toward said circuit board.
