PROBLEM TO BE SOLVED: To surely mount a component while shortening the tact time of component mounting in the mounting head of a surface mounting machine for vacuum sucking and mounting a component on a substrate by a nozzle.SOLUTION: The mounting head of a surface mounting machine includes: a spool valve for allowing a spool 61 to move from an initial position A to a positive pressure switching position C for performing switching to a positive pressure supply path 62b; control means for controlling the movement of the spool 61; and a landing detection sensor for detecting that a component sucked by a nozzle has landed on the substrate. The control means is configured to, before the component sucked by the nozzle has landed on the substrate, allow the spool 61 to move to a preparatory position B between the initial position A and the positive pressure switching position C, and to, when the landing of the component is detected by the landing detection sensor, allow the spool 61 to move from the preparatory position B to the positive pressure switching position C.SELECTED DRAWING: Figure 8 |
