  • Patent number: 10820461
    Abstract: In a component mounting machine, before the suction nozzle held by the rotary head is automatically exchanged, the nozzle ID codes of all suction nozzles arranged on the nozzle station are continuously read at a high speed and stored in association with the position of each suction nozzle. Sequentially imaging the nozzle ID code display section of each suction nozzle of each column is performed without stopping the mark imaging camera while moving the camera in an arrangement direction of the suction nozzle of each column of the nozzle station. The movement direction of the camera is reversed each time the last imaging operation of one column is completed and the camera is moved to imaging an adjacent column and the nozzle ID code of each suction nozzle of each column read at the image processing is stored in the storage in association with the position of each suction nozzle.

  • Patent number: 10729049
    Abstract: In component mounting device, if a rotary head held by a head holder greatly deviates from a specified reference, a CPU executes a process for a holding error. The process for the holding error includes a process of holding a rotary head again by the head holder or the like, for example. If the rotary head greatly deviates from a specified reference and the component mounting process is executed as is, there is a fear that poor precision will occur during component mounting. Therefore, the CPU does not execute the component mounting process but executes the process for the holding error.
