PROBLEM TO BE SOLVED: To achieve control that stabilizes an absorption state of a component absorbed to an absorption nozzle of a component mounting device with low power consumption.SOLUTION: Each mounting head 24 holding an absorption nozzle 26 is provided with a vacuum pump 27. The vacuum pump 27 is constituted to adjust negative pressure supplied to the absorption nozzle 26 by adjusting the number of rotation of the pump. A control device 31 of a component mounting device 10 determines an absorption state (a displacement amount of the absorption position and a component absorption posture) of the component absorbed to the absorption nozzle 26 and adjusts the number of rotation of the pump of the vacuum pump 27 according to the determination result to adjust the negative pressure supplied from the vacuum pump 27 to the mounting head 24 and to adjust absorption force of the absorption nozzle 26, thereby stabilizing the absorption state of the component. This can eliminate the necessity of maintaining the negative pressure of the vacuum pump 27 at a constant relatively large negative pressure during production and achieve control that stabilizes an absorption state of the component absorbed to the absorption nozzle 26 with low power consumption.SELECTED DRAWING: Figure 2 |
