In the past few years, we have covered plenty of cool applications for Fanuc robots. Minatech has partnered with Herrmann Ultrasonics to develop this ultrasonic welding system with automatic tool changeover. As the company explains, this system is capable of handling different types of welds without need for a technician.
Here is how it works:
When the cycle starts, the FANUC M-20iB/25 robot picks up the first stack and performs several staking operations. It changes over to a second staking tool with internal air cooling, and performs additional staking operations. During the staking operations, the FANUC robot welds by distance collapse to precisely control how far to collapse the staking post. The distance is measured by a precision linear encoder on the pneumatic actuator.
