Patent ID: 7025244

Claim:
An electronic component mounting apparatus comprising: a holding unit holding a board; a mounting head equipped with a plurality of mounting nozzles for sucking/holding electronic components and having a mounting nozzle elevation mechanism for separately elevating said plural mounting nozzles; electronic component supplying means which supplies the electronic components to said mounting head; a mounting head transport mechanism which transports said mounting head between said holding unit and said electronic component supplying means; an observation head which acquires both an image of a provisionally positioned electronic component and an image of an electronic component mounting portion from a space defined between the electronic component mounting portion and the provisionally positioned electronic component under such a condition that the electronic component sucked/held by said mounting nozzle has been provisionally positioned above a plurality of electronic component mounting portions formed on said board; an observation head transport mechanism which transports said observation head in synchronism with the electronic components which are sequentially and provisionally positioned by moving said mounting head, and also evacuates said observation head from an upper space of said holding unit when the electronic component is mounted on the board; and control means which controls said mounting head transport mechanism based upon both the image of said electronic component and the image of said electronic component mounting portion, which have been acquired by said observation head, so as to sequentially position the electronic components sucked/held by the respective mounting nozzles with respect to the electronic component mounting portions corresponding thereto.
