Mobile robot cell for medical parts production
Our R-Cobot mobile robot cell ensures safe loading and unloading of turning/milling machines in medical parts production environment. Two safety area scanners and other intelligent functions contribute to safety, precision and ease of use in 24/7 operation.
The challenge
A medtech company manufactures high-precision medical parts in a very confined space. The turning/milling combination machines run in 24/7 operation - it process the blanks with micrometer precision. A mobile robot cell was to enable unmanned loading in order to ensure the desired high productivity around the clock. The challenges were the tight space conditions, the high variety of references and the desire for a cell without a safety fence for easy, barrier-free accessibility.
The solution
A modular R-Cobot base cell, equipped with a FANUC industrial robot type LR-10iA, forms the heart of the mobile robot system. The robot arm with multifunctional gripper has a DualCheckSafety option and two safety area scanners. This allows the turning/milling machine to be loaded and unloaded without barriers. An automatic start-up, which takes place after filling the parts supply and leaving the safety zone, further increases operating convenience.
The robot's travel speed outside the machine is limited and safe. However, a fast change/blow-off cycle can be run inside the machining area. This significantly reduces machine downtime. Safety is monitored by two area scanners with a safety PLC.
Intelligent functions such as a touch gripper, regripping station, blow-off chuck and loading press-on function make the mobile robot cell very functional. Our easy-to-use user interface simplifies the teaching and run-in of new reference parts. The wheeled cell, fixed in place with a precise click-release system, can be quickly removed and returned for cleaning purposes.
“The modular concept ensures flexibility in use and enables uncomplicated cleaning. Nevertheless, the robot cell works with maximum precision and is safe and easy to operate.”
The project
Modular cells with robots and multifunctional grippers enable high functionality and efficiency on a small footprint. The areas monitored by safety area scanners set a new comfort and safety standard for automation cells and make an industrial robot with all its speed and durability a better cobot.
