Protect gripper from vibrations
Gripper systems are part of highly dynamic robot systems; at the same time, grippers must be designed to be rigid and weight-optimized. Force application and robot path planning are responsible for avoiding vibrations and thus for the reliable operation of a gripper system.
Due to the robot acceleration and deceleration, the gripper components are subject to constantly changing force effects in all directions. Robot path planning has a decisive influence on the vibration behavior of the gripper. A poorly programmed robot path or an insufficiently rigid base frame design can cause vibrations on the gripper, which have a negative effect on the gripper components and can lead to premature failure.
Autarkic acceleration sensors can be used to evaluate the robot path and the gripper during the running process (run at rate). You can connect to a web server integrated in the Trec via WiFi, record the accelerations on the gripper system and save them. The acceleration values can then be evaluated using a smartphone, tablet or notebook. In addition to the self-sufficient Trec measuring system, Tünkers also offers an EGBE sensor that is installed stationary on the gripper system.
The evaluation of the acceleration curves allows important conclusions to be drawn about actual loads and load peaks, vibration behavior, quality and optimization potential of the robot programming, the gripper structure, early detection of possible material failure and detection of invisible structural defects, for example after a crash.
With the help of the recorded data, the customer can monitor the condition of the system and carry out a diagnosis in the event of faults. In addition, maintenance can be carried out on the devices in a targeted manner and machine downtimes due to faults can be minimized. as
