Eliminating adhesive leakage when stacking PTC heaters for TDK Šumperk
Gluing ceramic plates for PTC heaters by hand was slow, and adhesive leaked out at the sides. We built GLUSTA, a automatic machine that takes the plates from the press, glues them and stacks them.

Gluing ceramic plates by hand was slow and adhesive leaked out at the sides
PTC heaters for cars use ceramic plates that have to be glued together into a stack. This was done by hand. Besides being slow, the process let adhesive leak out at the sides of the plates.
TDK Šumperk needed a automatic machine that would take the plates after pressing and stack them - fast enough to keep up with the press and precise enough to eliminate adhesive leakage.
A special gluing technology and a two-axis vacuum manipulator for stacking
We built GLUSTA, a large and mechanically demanding machine in which the biggest engineering challenge was designing how the plates are transferred to the adhesive and precisely stacked. It uses a special gluing technology that is not publicly available.
Much of the engineering went into positioning accuracy and cycle speed - everything is done with servo axes and aligners, plus a buffer for finished stacks that extends the machine's autonomy. The operator at the output buffer only removes finished stacks by hand.
