Component pickup position correction system and component pickup position correction method for a rotary head type component mounter

A component pickup position correction system of a rotary head type component mounter, the system comprising:

• multiple tape feeders configured to feed a component stored in component supply tape to a component pickup position by performing feeding operation of the component supply tape;
• a rotary head configured to hold multiple suction nozzles at a specified interval in a circumferential direction;
• a head rotating mechanism configured to revolve the multiple suction nozzles in the rotation direction of the rotary head by rotating the rotary head;
• a Z-axis drive mechanism configured to cause pickup of the component by lowering the suction nozzle that is positioned above the component pickup position of one of the multiple tape feeders;
• a head moving mechanism configured to move the rotary head in XY directions between a component pickup station at which component pickup operation is performed and a component mounting station at which component mounting operation is performed;
• and
• processing circuitry configured to correct the component pickup positions, wherein
• the Z-axis drive mechanism is provided in two locations, and is configured to simultaneously pickup leading components in two of the multiple tape feeders by simultaneously lowering two suction nozzles of the multiple suction nozzles that are positioned above the component pickup positions of the two of the multiple tape feeders, and
• the processing circuitry corrects the component pickup positions of the leading components of the two tape feeders by:
• moving the rotary head in the XY directions with the head moving mechanism and rotating the rotary head with the head rotating mechanism such that pickup points of the two suction nozzles are positioned on two straight lines extending in a tape feeding direction of each of the two tape feeders,
• calculating corrected tape feeding amounts of each of the two tape feeders to supply the leading components of each of the two tape feeders to the pickup points of the two suction nozzles on the two straight lines, and
• feeding the leading components of the two tape feeders with the corrected tape feeding amounts to the component pickup positions that are the pickup points of the suction nozzles on the two straight lines.
