In industrial settings, a robot’s ability to perform multiple tasks without direct human intervention is essential for maximizing efficiency. Automatic tool changers allow robotic arms to switch between different devices—such as grippers, suction cups, or welding torches—without halting production. FANUC, a leader in automation, has developed solutions that integrate this functionality to offer greater flexibility and minimize downtime.
A robotic tool changer is a mechanism that enables a robot to automatically attach and detach various work tools. This eliminates the need for manual intervention, saving time and reducing risk. Within FANUC’s lineup, models like the FANUC M-20iA and FANUC R-2000iC benefit from integration with automatic tool changers developed by companies such as Schunk and ATI Industrial Automation, both of which offer systems compatible with FANUC protocols.
These changers feature fast and secure coupling via pneumatic or electric actuation, built-in connections for electrical signals, air, and even fluids, and position detection to ensure the tool is properly locked in place.
Thanks to this technology, a single robotic cell can handle a wide range of processes—from palletizing and depalletizing to welding, handling, cutting, polishing, and measuring—without interruption.
At a home appliance manufacturing plant in Spain, a FANUC R-2000iC system was implemented with an automatic tool changer. The robot switches between a handling gripper for moving casings and a sealing gun for applying adhesive. The results were striking: tool change time dropped from 10 minutes to under 5 seconds, production increased by 25%, and tool wear was significantly reduced thanks to more precise coupling.
Automatic tool changers dramatically expand a robot’s capabilities, allowing a single workstation to perform diverse tasks without extended pauses. In FANUC’s case, this versatility—combined with mechanical reliability and precision—makes its robots an ideal solution for companies seeking flexibility without compromising on quality.
