Cassettes contain electronic parts. First and second feeders are operative for feeding the electronic parts from the cassettes. A first mounting head has sucking nozzles for picking up the electronic parts fed by the first feeder. A second mounting head has sucking nozzles for picking up the electronic parts fed by the second feeder. A table arrangement is operative for holding a printed circuit board. The first and second mounting heads are alternately moved along a first direction to a region above the printed circuit board on the table arrangement. The table arrangement includes a mechanism for moving the printed circuit board on the table arrangement in a second direction perpendicular to the first direction. Also, the table arrangement includes a mechanisms for rotating the printed circuit board on the table arrangement about an axis perpendicular to both the first and second directions. The sucking nozzles of the first mounting head place the electronic parts on the printed circuit board on the table arrangement when the first mounting head is in the region above the printed circuit board. The sucking nozzles of the second mounting head place the electronic parts on the printed circuit board on the table arrangement when the second mounting head is in the region above the printed circuit board.

Chip-type electronic part storage casing and supply cassette using same

A chip component feeder is provided which includes a chip component storage box, a pick-up slider, a first feeding unit, and a second feeding unit. The pick-up slider slides to enter an outlet of the chip component storage box for picking up chip components and leads them to a feeding path formed in the first feeding unit communicating with the second feeding unit. The feeding path of the first feeding unit has a rectangular cross section suitable for the chip components of rectangular shape as well as square or circular shape.

There is disclosed an automatic electronic part-mounting apparatus in which acceleration, acting on electronic parts, suction-held respectively by mounting heads, is reduced, thereby enabling stable mounting of the electronic parts. Cam levers 10 are pivotally mounted through respective pivot shafts 9 on a rotary member 8 which is rotated at a constant speed by a roller gear cam 19. One end of the cam lever is engaged with a fixed cam 7 whereas the other end thereof is slidably mounted through cam followers on a follower lever 12 slidably mounted on annular rails 11 in a housing 6. One end of the follower lever 12 is slidably engaged with a cam follower, and the other end of the follower lever 12 is mounted on each mounting head 13. With this construction, the acceleration of the mounting head 13 can be reduced.

A chip component supply apparatus of the invention includes a container box for storing chip components in pieces, a means for conveying chip components from the container box onto a conveyor belt, which moves intermittently and conveys the transferred chip components toward a take-out port area where a vacuum suction nozzle of an electronic component placement machine takes out the chip components. A stopper is positioned in the vicinity of the take-out port area for stopping the chip components conveyed by the conveyor belt at the take-out port area. The stopper moves and departs from the vicinity of the take-out port area when the conveyor belt finishes intermittent motion and stops, and returns and is positioned at the take-out port area before the next chip component conveyed by next intermittent motion of the conveyor belt reaches the take-out port area. The vacuum suction nozzle of the electronic component placement machine takes out the chip component at the take-out port area when the conveyor belt is stopped and the stopper is apart from the take-out port area.
