  • Patent number: 11337351
    Abstract: Each of multiple component mounting machines constituting a component mounting line is configured to switch between a production mode in which a component is mounted on a circuit board that has been conveyed in and then conveyed out, a mounting accuracy measurement mode in which a mounting accuracy measurement component is mounted at a predetermined position on a mounting accuracy measurement board and the mounting accuracy is measured, and a pass mode in which a component is conveyed out without being mounted on the board conveyed in. When the control mode of two or more component mounters among the multiple component mounting machines is the mounting accuracy measurement mode, the mounting accuracy is measured by conveying the mounting accuracy measurement board along the board conveyance path, and the two or more component mounting machines sequentially use the mounting accuracy measurement board to measure the mounting accuracy.

  • Patent number: 10925200
    Abstract: A component mounting system starts mounting processing in a state in which a portion of the initial set target feeders of the multiple feeders required for mounting processing are set in supply area of component mounter, and in which remaining feeders are not set in supply area of component mounter. Mounting processing is performed while switching feeders that have finished supplying components with remaining feeders using exchange robot during mounting processing of a single board. By this, because it is possible to perform mounting processing while exchanging required feeders within the range of the upper limit loading quantity of component mounter, it is possible to improve the efficiency of mounting processing.
