Component mounting method

A component mounting method in which a carrier tape provided with pockets receiving components is pitch-fed by a tape feeder and each of the components pitch-fed to a component pickup position is sucked and held by a suction nozzle and mounted onto a substrate, said component mounting method comprising:

• executing a suction failure recovering process when a suction failure in which the suction nozzle fails to normally suck and hold a component is detected once or continuously a predetermined number of times or more,
• wherein the suction failure recovering process comprises:
• executing an imaging process in which the carrier tape is pitch-fed and an image of the pitch-fed pocket is obtained by an imaging unit moved to the component pickup position;
• executing a pocket position detection process in which recognition processing is performed on the obtained image and a pocket position is detected;
• and
• executing a positional displacement determination process in which it is determined whether the detected pocket position falls into a permissible range or not;
• wherein when it is determined that the pocket position does not fall into the permissible range in the positional displacement determination process, the imaging process, the pocket position detection process and the positional displacement determination process are executed sequentially and repeatedly until the pocket position falls into the permissible range, and
• wherein when it is determined that the pocket position falls into the permissible range in the positional displacement determination process, a correction process is executed to correct a suction position based on the pocket position at a time point at which the pocket position falls into the permissible range.
