Abstract: The present invention provides a mounter air controller capable of executing appropriate air control associated with replacement of a nozzle without stopping operation of a mounter. This mounter air controller includes: a flow rate adjustment mechanism 4 mounted on a head module HM of the mounter; and control means 5 that controls this flow rate adjustment mechanism 4. The flow rate adjustment mechanism 4 is interposed between a positive-pressure region and a nozzle n and has a function capable of continuously changing a flow rate of passing air. The control means 5 is configured to bring the nozzle n to have a negative pressure and then control the flow rate in the flow rate adjustment mechanism 4 on the basis of an applied voltage or an applied current, which is determined in advance, so as to supply the air to the nozzle n.

Abstract: In an invention including: a piezoelectric element (13) which generates, as a displacement, a driving force necessary for an operation of a valve body (12) which is an operating body; a displacement enlarging mechanism (14) including at least a spring element so as to enlarge a displacement of the piezoelectric element (13) which acts on the valve body (12); and a driving device (15) which operates the valve body (12) by applying a voltage to the piezoelectric element (13) to extend the piezoelectric element (13), the driving device (15) includes a first filter processing unit (15x) having an inverse function characteristic of a mechanical resonance frequency when operating the displacement enlarging mechanism (14), and is configured to apply, a voltage which reduces the mechanical resonance, to the piezoelectric element (13) through this resonance suppression processing unit (15x).

Abstract: This air control device for mounter is to solve a problem of realizing an air control device for a mounter capable of providing a secured holding state by a nozzle without damaging a part by adjusting, during vacuum suction, an amount of air to be drawn suitably for the part and the nozzle. This air control device for mounter is configured such that a nozzle n detachably attached to a head module HM of a mounter is connected to a negative pressure region, and a part is suctioned at a distal end of the nozzle n. The head module HM is mounted with a variable throttle mechanism 4, and by using the variable throttle mechanism 4, an amount of air to be drawn into the negative pressure region from the nozzle is adjustable.
