Assembly of Modules with Three Robots and Vision Systems

Initial Situation & Goals

Actuators are ubiquitous in HVAC applications such as building climate control.

The Swiss high-tech plastic processor Wild & Küpfer needed a new, compact assembly system for the production of motor print carriers, where precise plastic parts from their own injection molding are assembled into modules. These consist of small electric motors, gears, and circuit boards.

A particular challenge was the recognition of these parts, which are delivered in cardboard boxes.

The Solution

The centerpiece of the system is a compact Robot Cell with three long-arm 6-axis robots from FANUC. Using a Vision System , the parts in the cardboard boxes are recognized and then positioned on a rotary indexing table. There, fully automated assembly into modules takes place over several stations.

The robots perform sorting, positioning, pressing, and control operations in quick succession, while tiered conveyors supply new cardboard boxes and remove the assembled modules.

Finally, the finished modules are inspected, packaged, and shipped to construction sites worldwide for final assembly outside the cell.
