Precise Positioning with Single Image Capture The MYVIS positioning application software that is supported by Yaskawa considers total servo motion The present positions of the servo s axes are constantly obtained and images are processed using the servo coordinates This means that even if the center of the 0 axis should move in the X and Y axis directions accurate 0 axis center coordinates are determined to achieve the target precision with a single positioning correction Y Basic Positioning Calculation As shown in figure at right two alignment mark coordinates are used to perform the calculation in units of servo axis movement The inclination from the center of the axis is corrected to move the mark to the reference point iti Reference point target position target position 2 X axis correction 1 2 and 3 are calculated simultaneously Q axis center Example Before positioning correction After positioning correction In the figure at right the left mark is SER being centered in the search area of a TT the left side camera camera 1 This enables various combinations of processing including processing center position of the marks and processing with four cameras Non stop Alignment In contrast to a system where the target object stops in front of the camera for processing this system shortens the overall mount time with non stop processing 3 0 second Cycle Time 1 5 sec
