Patent ID: 7748112

Claim:
A component mounting apparatus for mounting a plurality of components in a stacked manner, comprising: a stage with a fixed height position; a mounting head adapted to releasably hold one of the components mountable in a stacked manner, to be moved downward toward the stage from a first reference height position fixedly positioned above the stage, and to sequentially mount the component held by the mounting head on an upper-most component at the stage in a stacked manner; a recognition camera capable of recognizing the component held by the mounting head and the upper-most component at the stage; and a controller for controlling the mounting head so as to repeat a mounting operation in which another one of the components is held by the mounting head and sequentially mounted on a respective upper-most component at the stage, wherein the controller comprises a mounting reference height calculation unit for calculating, for each mounting operation, a mounting reference height corresponding to a distance from the first reference height position to a mounted surface of the upper-most component at the stage such that the mounting reference height approaches the first reference height position as a number of components sequentially mounted at the stage increases, and a first target movement height calculation unit for calculating, for each mounting operation, a first target movement height based on at least the mounting reference height calculated by the mounting reference height calculation unit and a thickness of the component held by the mounting head, the first target movement height decreasing as the number of components sequentially mounted at the stage increases, wherein the controller, for each mounting operation, makes the mounting head execute an alignment of the component held by the mounting head with the upper-most component at the stage based on a recognition result of the recognition camera, and then moves the mounting head downward from the first reference height position to the first target movement height to mount the component held by the mounting head on the upper-most component at the stage.
