Mounting accuracy measurement system and mounting accuracy measurement method for component mounting line

摘要

Each of multiple component mounting machines (14) constituting a component mounting line (10) is configured to switch between a production mode in which a component is mounted on a circuit board (11) that has been conveyed in and then conveyed out, a mounting accuracy measurement mode in which a mounting accuracy measurement component (42) is mounted at a predetermined position on a mounting accuracy measurement board (41) 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 constituting the component mounting line (10) is the mounting accuracy measurement mode, the mounting accuracy is measured by conveying the mounting accuracy measurement board along the board conveyance path (12) at least between the two or more component mounting machines, and the two or more component mounting machines sequentially use the mounting accuracy measurement board to measure the mounting accuracy.
