  • Patent number: 11109520
    Abstract: In a rotary head type component mounter, among a specified quantity of suction nozzles held by a rotary head, multiple suction nozzles are lowered simultaneously. When the rotary head is moved by a head moving mechanism to a nozzle exchange area and exchange of suction nozzles is performed, two station reference marks of the nozzle station are imaged by a mark imaging camera, image recognition is performed of the positions of the two station reference marks, and the position and angle of the nozzle station is calculated. Then, the position and angle of the rotary head is corrected to be aligned with the position and angle of the nozzle station, multiple of the suction nozzles held on the rotary head are lowered simultaneously by Z-axis driving mechanisms and simultaneously exchanged with multiple of the suction nozzles in the nozzle station.
