HANDLING WORK PIECES WITH FORCE-TORQUE SENSORS
While handling work pieces, the robot usually moves on a predefined trajectory and at a predefined speed. The “resistances” affecting the work piece are not taken into account. In many cases, however, these very resistances have a decisive impact on the quality and process security of the application. The robot, equipped with a force-torque sensor, reacts to its environment and deviates from the pre-programmed trajectory or speed depending on the feedback received. This reduces the risk of damaged parts.
ASSEMBLING WORK PIECES WITH FORCE-TORQUE SENSORS
When assembling component parts and work pieces, the force-torque sensor system ensures, among other things, adherence to exactly defined process forces, the balancing of component part tolerances and position inaccuracies, as well as adjustment with regard to mechanical stops and beveled edges.
In addition, a robot can be programmed such that it imitates human motion sequences. This makes it possible to automate complex assembly tasks using robots.
- Improved ergonomics and employee relief as monotonous, repetitive and exhausting tasks, such as overhead work, are performed by robots
- Reduced risk of handling and assembly errors that might lead to production problems or damaged parts
- Consistently high quality in reproducible processes
- Increased plant availability thanks to fewer downtimes
APPLICATION: LOADING/UNLOADING OF MACHINES AND BASE FRAMES IN AUTOMOTIVE MANUFACTURING
PRESENTATION OF PROBLEM
In automotive production, modern handling robots take on the handling of structural component parts with complex geometries. The loading and unloading of load carriers and machines, however, are still frequently carried out without monitoring the arising process forces. This makes the detection and rectification of incidents impossible.
The integration of a force-torque sensor facilitates the setup of the robot as well as the configuration of monitoring functions using hand-guided programming. For more demanding solutions, the sensor is integrated into the gripper system and additionally takes on the process monitoring and control.
