ABSTRACT:
An apparatus for automatic glazing of cars which comprises a robot having a robot arm. A tool is mounted on the robot arm for gripping a window glass, and two T.V. cameras are fixed along a conveyor line for respectively taking images of front and rear pillars of a body shell stopped at a predetermined position. T.V. cameras are mounted on the gripping tool for taking images of a window frame for position compensation of the window glass, and an image processing unit is provided for distinguishing the kinds of body shells and for calculating position variations of the stopped body shell with respect to predetermined positions thereof from the images. A control unit is provided for receiving signals corresponding to the position variations from the image processing unit and for moving the robot so as to compensate for position variations.
