リブレーシヨン機能付ワーク位置決め装置。 An XYθ table, an image processing device that images the position measurement mark of the target workpiece mounted on the XYθ table, calculates and outputs the position data through image processing, and calculates the amount of correction for each axis of the XYθ table based on the position data. In a workpiece positioning device including a calculation section and a table control section that drives the XYθ table according to the correction amount of each axis, the mounting position repeatability accuracy is set to a value sufficiently smaller than the required positioning accuracy using a pin or a guide with respect to the XYθ table, and the An image processing device stores a jig plate having a position-measurable reference mark within the field of view at a reference setting position of an imaging camera, coordinate data in an XYθ table coordinate system regarding the reference mark on the jig plate, and stores the XYθ table. With an automatic calibration function, comprising: a camera position calculation section that calculates a camera setting position from image processing measurement position data of the reference mark obtained by rotation and the reference mark coordinate data and outputs it to a calculation section. Work positioning device.
