Use a Tool Changer also for High-Accuracy Robotized Tasks

Epsilon 160 for glue gun or industrial riveter

Nowadays the ecological challenges push car manufacturers to find new ways to make their cars more energy efficient. Coupled with the need for increased automation in manufacturing plants to answer economical pressure, this brings new applications that need to be operated by robots. Indeed, new lighter materials such as aluminum or composite materials cannot be assembled with traditional processes such as spot welding. They need to be tightened together with rivet or glue for example.

Those operations require special tooling that needs to be accurately handled and monitored with dedicated sensors in order to ensure repeatability. PES has already implemented tool changing systems for such special operations. Our custom module design and manufacturing capabilities help us to adapt to any kind of equipment that is present on the robot end-of-arm while the cam lock mechanism with integrated wear compensation ensure the accuracy and repeatability that riveting or gluing applications need.

Electrical Features
