Abstract

To provide a method for calibrating the position of a camera by which a deviation between the mutual coordinate system of the part recognition camera and coordinate system of the substrate recognition camera can be calibrated simply and rapidly.In the method for calibrating the deviation of the places of the cameras, a fixture part 30 enabled by both recognition methods is used. The method has an image pick-up process in which the part 30 is image-picked up by the part recognition camera first, the image pick-up process in which a fixture substrate is image-picked up by the substrate recognition camera 17, a mounting process in which the fixture part 30 is mounted, a computing process in which the center of the part is obtained by the substrate recognition camera 17 and the quantities of displacements obtained respectively with the place of the recognition center of the camera 17 are computed in the mark of the fixture part 30 after the mounting, and a calibrating process in which the coordinate systems of the camera 17 or the camera 16 are calibrated on the basis of the quantities of the displacements.

Description

technical field [0001] The present invention relates to a camera position deviation correction method and device for correcting a mutual deviation between a coordinate system of a component recognition camera and a coordinate system of a board recognition camera in an electronic component mounting apparatus and the like, and camera position correction Fixture substrates and fixture components used. Background technique [0002] In an electronic component mounting apparatus, a board recognition camera is used to image a board mark or an IC mark on a board carried into a main body of the device to recognize the position of the board. Then, electronic components mounted on the substrate are imaged by a component recognition camera to perform position recognition, and based on the recognition results, the positions of the electronic components are corrected, and then the electronic components are mounted on the substrate. [0003] In this case, if the coordinate system of the p...
