Method for Detecting Condition of Nozzle Member, Method for Detecting Holding of Components, Method and Apparatus for Mounting Components

摘要

An apparatus for mounting components provided with a multi-nozzle type component mounting head for moving vertically includes a plurality of movable parts linearly arranged; a plurality of nozzles respectively connected to tip parts of the movable parts; a height detector for detecting positions of the plurality of movable parts; a light projector provided on an extension of an arrangement of the plurality of nozzles; a light receiver provided at a position opposed to the light projector, wherein all of the plurality of nozzles are made to stand-by on an upper side of an optical axis L from the light projector, an arbitrary one of the nozzles is made to descend, and at a timing when the light receiver detects that light shielding of the light from the light projector is switched by the tip part of the nozzle, a vertical position of the movable part is measured by the height detector.
