Component supply head device and component mounting head device

Abstract

A suction nozzle ( 65 ) of a reversing head device ( 22 ) has a distal end surface ( 65 a ) with a suction hole ( 65 b ) opened therein, and a suction passage ( 65 c ) communicated with the suction hole ( 65 b ) at one end thereof. A portion of the distal end surface ( 65 a ) outside of the suction hole ( 65 b ) abuts against bumps ( 39 ) of an electronic component ( 12 ). The suction hole ( 65 b ) is opposed with a gap to a portion of a mounting side surface ( 12 a ) where no bumps ( 39 ) are present. A vacuum pump ( 65 ) creates an air flow that flows from the gap between the suction hole ( 65 b ) and the mounting side surface ( 12 a ) into the suction passage ( 65 c ) through the suction hole ( 65 b ). The electronic component ( 12 ) is held at the distal end surface ( 65 a ) by a negative pressure generated by the air flow.
