The robot cell has been tailored to perform the impregnation of inductive components using fast-drying varnish. This is the first time this manual production process has been automated. Our team invested significant effort into research and experimentation to ensure a stable process with high-quality output, short cycle times, and user-friendly operation. The main challenge was automating the application of varnish. We devised a custom system in which varnish application is carried out using a motorized, custom-made paint roller. This allowed us to paint only the four sides of the components with high precision.
