COMPONENT MOUNTING MACHINE
First Claim
1. A component mounting machine comprising:
- a mounting head that holds a plurality of suction nozzles;
a plurality of conveyors disposed in parallel to transport a plurality of circuit boards in parallel;
a head driving device that moves the mounting head across the plurality of conveyors and mounts a component sucked by a suction nozzle of the plurality of suction nozzles on to the circuit boards transported by each conveyor; and
a control device that controls the plurality of conveyors and the head driving device,wherein the head driving device has a nozzle lifting mechanism which individually lifts up and down the plurality of suction nozzles during component suction and component mounting, and an XY moving mechanism which moves the mounting head in an XY direction,wherein the head driving device has a head lifting mechanism which lifts up and down the mounting head,wherein when the control device causes the XY moving mechanism to move the mounting head across the plurality of conveyors after a component suction operation and there is a possibility that the component sucked by the suction nozzle may interfere with a mounted component on the circuit board on any of the plurality of conveyors, the control device causes the head lifting mechanism to lift up the mounting head to a height position where the component sucked by the suction nozzle does not interfere with the mounted component, wherein thereafter, the control device causes the XY moving mechanism to move the mounting head upward of a target conveyor, and causes the head lifting mechanism to lower down the mounting head to an initial height position, and wherein thereafter, the control device causes the nozzle lifting mechanism to lower down the suction nozzle and to mount the component on the circuit board on the conveyor.

Abstract
When a mounting head is moved upward of a rear side conveyor across and over a front side conveyor after a component suction operation, it is determined whether or not there is a possibility that a component sucked by a suction nozzle may interfere with a component mounted on a circuit board on the front side conveyor. When so determined, a head lifting mechanism is caused to lift up the mounting head to a position where the component sucked by the suction nozzle does not interfere with the mounted component. Thereafter, the mounting head is moved upward of the rear side conveyor, and the head lifting mechanism is caused to lower down the mounting head to an initial height position. Thereafter, the component is mounted on a circuit board on the rear side conveyor.
