Abstract

A rotary head of a surface mounter includes a rotating body, an N-shaft servo motor configured to rotate and drive the rotating body, and a plurality of suction nozzles attached to the rotating body in such a manner as to be movable in a direction of a rotation axis. The plurality of suction nozzles are arranged on the circumference of a circle with the rotation axis as the center, and the plurality of suction nozzles are configured to hold and release a component. The rotary head of a surface mounter further includes at least a pair of Z-axis drive devices spaced apart from each other in a rotation direction of the rotating body and configured to move, in the direction of the rotation axis, the suction nozzle that has moved to a predetermined drive position on the circumference of the circle.
