Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
161 words
An automatic mounting apparatus for mounting chip components on a printed circuit board, comprising a parts feeder including a plurality of exchangable parts hoppers which contain therein said chip components, a parts nest having a plurality of parts receivers connected through guide means to said hoppers for storing said chip components fed from said parts feeder in preparation for picking-up, a parts applicator including means for picking up said chip component and movable in orthogonal directions toward said parts receivers in programmed sequence, and means for transporting said printed circuit board to a position in proximity of said parts nest, said parts applicator being controlled in movement so that the chip components picked up from said parts receiver are moved to a predetermined position on said printed circuit board, and a common support frame for said parts feeder and said parts nest turnable about an axis from upright to fallen positions to remove the remaining chip components in said parts hoppers.
