In a vehicle production process, a system for detecting selected surface defects of a vehicle body prior to painting generally consisting of a conveyor operative for advancing a plurality of such vehicle bodies along a line of travel; an array of devices disposed transversely of the line of travel, operative to irradiate at the selected angles, sequential transverse sections of each of such vehicle bodies with grid patterns of light; a plurality of devices, operative to optically detect reflective grid patterns of light from the transverse sections; a computer including a processor and a database provided with files of reference data representing relevant defect surfaces of selected vehicle bodies, operative to process data generated by the detecting devices, utilizing triangulation techniques and accounting for three-dimensional phase shifts, to generate composite detected data, comparing such composite detected data with selected reference data to generate identification data representing coordinates of relevant defect surfaces of such vehicle bodies; and a substance emitting device operative in response to said identification data for marking relevant defect surfaces of such bodies.

Method for the automatic recognition of surface defects in body shells and device for carrying out said method

The present invention is a method and apparatus for repairing a coating defect. The apparatus includes a utility disk holder being mounted to a frame. The rotary disk contains a plurality of toolholes with a plurality of corresponding notches. A plurality of tools can be removeably secured to the plurality of toolholes. Each tool can be rotatably used to cure the coating defect.
