The present invention provides a recognition camera calibration device and a calibration method thereof, wherein the method includes the following steps: S1, driving the recognition camera to move in the vertical direction through the recognition camera adjustment plate, so that the center of the recognition area of the recognition camera is aligned with the calibration plate Calibration mark on the surface; S2, calculate the preset recognition distance, and the adjustment distance of the recognition camera relative to the calibration mark; S3, adjust the position of the recognition camera through the recognition camera adjustment plate according to the adjustment distance, so that the center of the recognition area of the recognition camera is aligned The recognition position is preset; during the movement, the movement distance of the adjustment plate of the recognition camera is measured by the distance measurement component, so that the movement distance is equal to the adjustment distance. The invention obtains the adjustment distance of the recognition camera through calculation according to the jump distance of the bonding point and the position of the calibration plate, and precisely adjusts the position of the recognition camera according to the adjustment distance, so that the recognition camera is accurately located at the preset recognition position.
Description
Technical field [0001] The present invention relates to the field of electronic label packages, and in particular, to identify camera calibration devices and a calibration method thereof. Background technique [0002] The market has a wide range of demand for electronic label packaging equipment. With the evolution of electronic components, the visual positioning of the equipment has put forward higher requirements, and the calibration method of the visual system also needs to continuously improve the upgrade. Since the positional error of the flexible carrier is large, the image recognition must be corrected to the position of the flexible carrier. There are many types of flexible carriers used in production, and each flexible carrier is different, the shapes are different, and the distance between the two neighboring points on the flexible carrier is also different. When replacing the flexible carrier, you need to adjust the location of the camera in the visual system according...
