Abstract:
An electronic component mounting apparatus comprising:a component supplying section for supplying electronic components; a component mounting section for mounting electronic components onto a mounting object; a plurality of suction nozzle sections for picking up electronic components by suction and mounting the electronic components onto the mounting object; and a head section provided with a plurality of suction nozzle sections disposed about an outer edge thereof, the operation of picking up and mounting said electronic components being performed by said suction nozzle sections at prescribed halt positions by said head section being rotated intermittently; wherein each of said suction nozzle sections comprises: a plurality of nozzle tip sections, a rod section for holding said nozzle tip sections so as to allow each of the nozzle tip sections to move upward and downward, said nozzle tip sections being disposed about an outer edge of the rod section, a motor section connected to the rod section for causing said rod section to rotate about a central axis of the suction nozzle section, a cylindrical cam section concentric with the rod section so as to be rotatable selectively together with and relative to the rod section, said cylindrical cam section having a cam surface that controls height positions of the nozzle tip sections when the cylindrical cam section is rotated with respect to the rod section, and a stopper section provided on an outer side of the cylindrical cam section for selectively halting the rotation of the cylindrical cam section while permitting the rod section to rotate relative to the cylindrical cam section thus causing said rod section to change height of the nozzle tip sections.
