Tailored condition determination: time signal analysis on robots
A company active in the automotive sector uses robots with a 7th axis.
The 6-axis robots stand on a guide system/track, which forms the 7th axis. In this way, the robot can perform its tasks over a length of 6-9 metres.
The Predictive Maintenance Department was asked to determine/monitor the quality of the bearings and guides.
As we are not dealing with a cyclical movement, time-waveform analysis was used.
In the above example, you can see a deviation in the connection of 2 guide rails.
In cooperation with the customer, we were therefore able to work out a measurement protocol, which detects even small deviations. This gives the customer the possibility to correct a small detected problem before it can cause a breakdown of the installation.
