Device mounter head and device mounting method using the same

A device mounter head comprising:

• a cylinder block unit comprising at least one cylinder in which a piston unit moving along the at least one cylinder is disposed;
• a pressure control unit which controls pressure inside the at least one cylinder so that the piston moves along the at least one cylinder based on the controlled pressure;
• a nozzle which is connected to the piston unit, and comprises an inlet exposed to an atmosphere outside the cylinder block unit and a nozzle communication vent connected to the inlet and provided with the controlled pressure, and
• a valve unit disposed between the cylinder block unit and another space, wherein the valve unit comprises a plurality of vents and moves relative to the cylinder block unit,
• wherein the inlet is configured to suck, grab and release a component using the controlled pressure, and
• wherein the cylinder block unit is configured to rotate around a central axis of the cylinder block unit so that pressure inside a first cylinder of the at least one cylinder is different from pressure inside a second cylinder of the at least one cylinder, whereby a first nozzle connected to a first piston in the first cylinder maintains a state in which a component is sucked and grabbed by a first inlet of the first nozzle when a second nozzle connected to a second piston in the second cylinder approaches another component to suck and grab the other component.
