The system detects the 3D coordinates of engine raw cast Motor parts and communicates it to a robot that picks the parts and forwards them to a transport system.
The various types of raw cast parts are poured into molds.
Due to the cast process sand remains as well as biscuits can cause a greatly different surface for the same part cast type.
After casting the up to 300° C hot parts are handeled by workers onto a tray transfer system.
Due to the different surfaces and shape differences, the position of the parts on the carrier varies up to 10 cm in 2 axis direction and up to 7 cm in rotation and height.
The vision system is able to compensate these deviations and to determine the exact 3D position information.
The tray is moved in front of the vision system and the cast type is identified by transponders.
The system inspects different types that have to be handeled differently by the robot.
The product type is communicated via a Profibus DP interface to the vision system.
The test area is evenly illuminated with high frequency fluorescent lamps with diffuse light. The System is using 4 cameras that are installed on the sides and top of the inspection position.
Finally the determined 3D position is communicated to the 6-axis coordinate system of the articulated robot.
For accurate position detection, the calibration of the cameras is carried out using of an individual calibration part.
