PROBLEM TO BE SOLVED: To provide an electronic component mounting device capable of reducing impact added to an electronic component during sucking and mounting the electronic component by a suction nozzle, with a simple structure and high responsivity.SOLUTION: An electronic component mounting device has servo motors 2a, 2b, and 2c for lifting/lowering suction nozzles 1a, 1b, and 1c; and a servo amplifier 3 for controlling the servo motors while receiving pulse signals from encoders 2d, 2e, and 2f of the servo motors. The electronic component mounting device sucks electronic components by the suction nozzles to mount them on a printed circuit board. The servo amplifiers set torque limit values when the suction nozzles are lowered, thereby controlling the servo motors; and decrease the torque limit values when a number of remaining pulses until a target position at which the suction nozzles contact with the electronic components or a target position at which the electronic components sucked by the suction nozzles contact with the printed circuit board becomes a predetermined number or less. |
