Automation of a potting process with the igus robot control software

The automated potting system for electronic assemblies from Simprop electronic Walter Claas GmbH & Co. KG uses a two-component polyurethane potting compound that completely encapsulates the electronics and protects them from dust and moisture. The system consists of a tank wagon for storing, tempering and vacuuming the components as well as a dosing head that dispenses the components in the correct mixing ratio into a static mixing tube. The potting compound runs into the housing of the assembly at the outlet of the mixing tube.

Automation has significantly reduced the manual activities at the workstation. The operators now only have to set and remove the workpiece carriers, top up the potting compound and hardener and carry out ancillary tasks at the start and end of work. This has resulted in a saving of around 60 % of working time. The sensory monitoring of the process and the PC-supported step-by-step instructions have reduced the number of operating errors to zero. The integrated production data acquisition logs the entire process and helps to identify maintenance requirements and further optimisation opportunities.
