IBG develops customized grippers for a wide variety of tasks based on many years of experience in the realization of production systems in almost all areas of industry. The screw grippers which are used when components have to be screwed together are another example. Force and torque are monitored as part of the process.
A six-axis robot with six bolting systems fixes the seat rails mounted in the interior from below, in order to then bolt them to the body by means of electric screw spindles, which are integrated on the robot gripper. The movement of the robot is synchronized with the conveyor technology of the vehicle.
The robots are equipped with grippers with two independent camera systems each to detect the wheel type, position, rotational orientation, and pickup height. Detection with a software specially developed by IBG (--> link). After gripping the wheel, the spatial position and rotational orientation of the wheel hub are detected. The synchronous bolting of the wheels to the vehicle movement is executed with the correction values from the vision system.
The manual frontend assembly is replaced by an automatic procedure. A gripper handles the insertion of the modules with a receptacle and is additionally provided with screwdrivers. A measuring system is installed on the gripper in order to detect the exact position of the body before the joining process, which measures the position of the bulkhead plates in the axes and forwards the correction data to the robot.
