  • Patent number: 11388849
    Abstract: A component mounting machine includes multiple component supplying devices, a head, a head moving device, and a nozzle lifting and lowering device. The component supplying device feeds out a component to a component supply position. The head includes multiple nozzles configured to suction a component. The head moving device moves the head to cause the nozzles to face the respective component supply positions with two or more thereof. The nozzle lifting and lowering device lifts and lowers the nozzle located to face the component supply positions. In positioning the nozzles to face the respective component supply positions, the head is moved so as to prioritize a positional correction of a nozzle facing a smallest sized component over positional corrections of the other nozzles, and in this state, the nozzles facing the respective component supply positions are lifted and lowered simultaneously to suction corresponding components.

  • 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.
