During the assembly of car seats, the different components are connected using rivets and screws.
This is done by a robot with 6 axes. The position of the seats can vary severely because of the diverse motor driven possibilities of adjustments. With a camera lighting unit which is mounted to the robot, the robot is guided to the proper work position.
With a camera the vision system detects the position of screws and rivet gaps at the driver seat frame.
These positions are forwarded to a robot which then tightens the screws or puts in rivets into the existing gaps.
The position is traced by the function "position detection with reference search".
This position is used by the system to determine the final position using a search for center of gravity limited to this area.
If the position is located too far off the center of the camera picture, the robot which also holds the camera will move accordingly. Then a new test will be performed. The high precise final position is sent to the robot through the serial interface.
