Electronic component mounting apparatus

摘要

Each of a plurality of suction nozzle sections (20) provided about the outer circumference of an intermittently rotating head section (21) comprises a plurality of nozzle tip sections (10) for picking up electronic components (22) by suction, these nozzle tip sections (10) being connected to a rod section (4), which is driven to rotate by a motor (1). A cylindrical cam section (8) having a cam surface (8a) and being able to rotate relative to the rod section (4) is provided such as to encase the nozzle tip sections (10), and one ends of the nozzle tip sections (10) engage with the cam surface (8a) of the cam section (8) via rollers (6), whereby the nozzle tip sections (10) are movable in a vertical direction. On the outer side of the cylindrical cam section (8), a stopper section (12) is provided for halting temporarily the rotation of only the cylindrical cam surface (8).
