Abstract:
An electronic component mounting apparatus comprising:a suction nozzle for sucking an electronic component and mounting the electronic component on a mounting board;a moving device for moving said nozzle in an upward direction and a downward direction;an air pressure switching unit for switching levels of air pressure to said nozzle when said nozzle is at an electronic component suction position and when said nozzle is at an electronic component mounting position; anda switching drive unit for operating said air pressure switching unit so as to independently control a timing point for a switch of air pressure levels to said nozzle when said nozzle is sucking the electronic component, and so as to independently control a timing point for a switch of air pressure levels to said nozzle when said nozzle is mounting the electronic component on the board, wherein a cycle rate of said nozzle is defined as a rate of travel of said nozzle from a first upper position through a lower position to a second upper position, said switching drive unit operating said air pressure switching unit based on said cycle rate of said nozzle.
