INTER-CAMERA CALIBRATION DEVICE FOR ELECTRONIC COMPONENT MOUNTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an inter-camera calibration device for an electronic component mounting device, which is adaptive to displacement due to temperature variation and secular change accompanying long-time use at any time, and allows calibration of high precision by reducing movements of an optical member and unnecessary calibration operations as much as possible.;SOLUTION: The inter-camera calibration device 20 includes: two optical members 21 and 22 that can move integrally with a component recognition camera 4 and have a half-mirror; and one calibration mark 23 which is recognized by two cameras 2 and 4 through the optical members 21 and 22. Then, the two optical members 21 and 22 are arranged such that when the inter-camera calibration device 20 moves to a predetermined position for the mark recognition camera 2 together with the component recognition camera 4, the total lengths of optical paths from the cameras 2 and 4 to the one calibration mark 23 have specified relation.;COPYRIGHT: (C)2011,JPO&INPIT
