A mounting-waiting process for making a substrate to be transferred into a mounting process wait before the mounting process; and a substrate discharge-waiting process for making the substrate transferred from the mounting process wait before the following process are provided. When transfer of an unmounted substrate into the mounting process and transfer of a mounted substrate from the mounting process to the substrate discharge-waiting process are performed simultaneously, it is detected, by a substrate-arrival detecting sensor for detecting the mounted substrate transferred to the substrate discharge-waiting process and a substrate-continuity detecting sensor for detecting the unmounted substrate continuously transferred following to the mounted substrate, that a plurality of substrates have been transferred into the discharge-waiting process continuously.

Substrate transfer apparatus for component mounting machine

A compact and high-speed automatic electronic parts mounting apparatus is provided which includes first and second parts feeders, first and second mounting heads, a printed board-holding table, and a controller. Each of the first and second parts feeders includes a plurality of cassettes storing therein electronic parts and having pick-up stations. The second parts feeder is arranged at a preselected interval away from the first parts feeder in a first direction. Each of the first and second mounting heads is movable in the first direction and includes a plurality of pick-up nozzles movable in a vertical direction for picking up the electronic parts from the pick-up stations of the cassettes. The printed board-holding table is disposed within the preselected interval between the first and second parts feeders so as to move in a second direction perpendicular to the first direction. The controller controls the movement of the table and the first and second mounting heads so that the first and second mounting heads pick up the electronic parts from the cassettes of the first and second parts feeders, respectively, and mount them on a printed board held on the table in sequential mounting operations.

High speed electronic parts mounting apparatus having mounting heads which alternately mount components on a printed circuit board

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.
