Patent ID: 7886427

Claim:
A component mounting head for sucking and holding a component so as to place the component at a component mounting position on a board and for releasing the suction and holding of the component to mount the component onto the component mounting position, the component mounting head comprising: a suction nozzle including a suction-and-holding face for sucking and holding the component; and an auxiliary suction member which is formed from an elastic material, the auxiliary suction member having an inner circumferential end portion and an outer circumferential end portion, wherein a suction hole is defined in the suction-and-holding face, the suction hole having a main hole portion and five extended hole portions, wherein the main hole portion is formed in a circular shape or a generally circular shape and is concentric with an axial center of the suction nozzle, wherein the five extended hole portions extend from the main hole portion in five radial directions, respectively, at a generally uniform angular pitch, wherein the five extended hole portions are integrally formed with the main hole portion such that the suction hole constitutes a single hole formed collectively by the main hole portion and the five extended hole portions, wherein the inner circumferential end portion of the auxiliary suction member is placed in close contact with an outer circumferential portion of the suction nozzle, wherein the outer circumferential end portion of the auxiliary suction member projects outwardly from a circumferential portion of the suction-and-holding face, wherein the outer circumferential end portion of said auxiliary suction member is placed at a position generally equal in height to the suction-and-holding face or slightly backward of the suction-and-holding face, wherein the suction nozzle includes an auxiliary suction member fitting portion which is set at an outer circumferential portion thereof such that the inner circumferential end portion of the auxiliary suction member is attached thereto and detachable therefrom, wherein the auxiliary suction member is selectively attached to the auxiliary suction member fitting portion depending on size of the component to be sucked and held, wherein a fixing member is provided for loading the auxiliary suction member to the auxiliary suction member fitting portion by releasably fixing a contact position of the inner circumferential end portion of the auxiliary suction member against the auxiliary suction member fitting portion, and wherein a height position of the outer circumferential end portion of the auxiliary suction member is adjustable by adjusting the contact position in a direction parallel to a longitudinal axis of the suction nozzle, the contact position being fixed by the fixing member.
