Component mounting device

A component mounting device configured to pick up a component by suction to mount the component on a target object, the component mounting device comprising:

• a negative pressure source configured to generate a negative pressure;
• a nozzle configured to pick up the component by suction at a suction port;
• a rotary head including a rotating body including multiple holders disposed in a circumferential direction, the holders each being configured to hold the nozzle and including a holder flow path formed in an interior space in such a manner as to communicate with the suction port of the nozzle;
• a rotating device configured to rotate the rotational body so as to revolve the multiple holders in the circumferential direction;
• multiple lifting and lowering devices configured to individually lift up and lower the holders, among the multiple holders, that are located in multiple predetermined revolving positions;
• multiple selector valves provided in such a manner as to individually correspond to the multiple holders to make and break communications between the holder flow paths of the corresponding holders and the negative pressure source;
• valve driving devices configured to drive the selector valves corresponding to the holders, among the multiple holders, that are located in the multiple predetermined revolving positions;
• and
• a control device configured to execute, when the component is requested to be picked up by suction, a suction operation in which the nozzle held by the holder located in either one of the multiple predetermined revolving positions is caused to suck the component by causing the lifting and lowering device and the valve driving device that correspond to the holder in question to lower the holder in question and to bring a state of the selector valve corresponding to the holder in question into a state where the selector valve switches to make the holder flow path in the holder in question communicate with the negative pressure source, a suction error determination determining whether a suction error has occurred in which the nozzle held by the holder in question fails to pick up the component by suction after the suction operation is executed, and, when the control device determines that a suction error has occurred, a negative pressure recovery operation in which, when the holder holding the nozzle on which the suction error has occurred is revolved to either of the multiple revolving positions, the valve driving device corresponding to the selector valve that corresponds to the holder in question is caused to bring the selector valve in question into a state where the selector valve switches to breaking communication between the holder flow path in the holder in question and the negative pressure source.
