Patent ID: 8881380

Claim:
A component mounting apparatus, comprising: a nozzle which sucks a component; a nozzle supporting member, on which the nozzle is installed, which moves in a vertical direction with respect to an upper surface of a substrate on which the component sucked at the nozzle is mounted; an optical system which captures an image of a leading edge portion of the nozzle where the component is sucked in a component mounting operation, from a side direction, such that an optical axis of the optical system is inclined at a predetermined angle with respect to a sucking surface of the nozzle; an analyzer which analyzes the image of the leading edge portion to determine whether a sucking state of the component sucked by the nozzle is normal or abnormal; a pixel rate storage which stores pixel rate data which is obtained by capturing an image of the component when the component is normally sucked prior to the component mounting operation, by the nozzle by using the optical system; and an image corrector which corrects image data of the component in the image of the leading edge portion captured in the component mounting operation, by using the pixel rate data stored in the pixel rate data storage.
