Electronic-parts mounting apparatus
First Claim
1. An electronic-parts mounting apparatus comprising:
- cassettes containing electronic parts;
first and second feeders for feeding the electronic parts from the cassettes;
a first mounting head having sucking nozzles for picking up the electronic parts fed by the first feeder;
a second mounting head having sucking nozzles for picking up the electronic parts fed by the second feeder;
a table arrangement for holding a printed circuit board;
first means for alternately moving the first and second mounting heads along a first direction to a position adjacent to the printed circuit board on the table arrangement;
second means contained in the table arrangement for moving the printed circuit board on the table arrangement in a second direction perpendicular to the first direction;
third means contained in the table arrangement for rotating the printed circuit board on the table arrangement about an axis perpendicular to both the first and second directions;
fourth means for allowing the sucking nozzles of the first mounting head to place the electronic parts on the printed circuit board on the table arrangement when the first mounting head is in the region;
fifth means for allowing the sucking nozzles of the second mounting head to place the electronic parts on the printed circuit board on the table arrangement when the second mounting head is in the region;
sixth means for detecting whether or not each of the electronic parts is normally held by the related sucking nozzle of the first mounting head;
seventh means for removing the electronic parts from the related sucking nozzles which are detected by the sixth means to be not normally held by the related sucking nozzles;
eighth means for detecting whether or not each of the electronic parts is normally held by the related sucking nozzle of the second mounting head; and
ninth means for removing the electronic parts from the related sucking nozzles which are detected by the eighth means to be not normally held by the related sucking nozzles.

Abstract
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.
