Sealing Bead Check for Passenger Car Windscreens via 2D/3D Profile Sensor

Before the final assembly of windshields on passenger car bodies, the outer edge of the glass panes is automatically fitted with a sealing bead by robot. A 2D/3D profile sensor mounted behind the dosing unit checks the correct application of the adhesive by measuring the bead profile with micrometer precision. The 2D height profile is assessed via the integrated uniVision standard software. If the measurement data deviates from the defined tolerance values, for example because insufficient sealing compound was applied, the robot is immediately stopped and the pane is ejected.

MLSL 2D/3D Profile Sensors

2D/3D profile sensors from the weCat3D series use the principle of laser triangulation to create 2D height profiles and 3D point clouds. The MLSL model provides accurate resolution in a compact housing design.
