The KIT-UR-QC is a manual tool changer kit for UR collaborative robots. It’s mainly composed of two parts: one permanently connected to the robot wrist (QCY90-A) and the other permanently connected to a tool (QC90-B). By operating a mechanical lever, the user can dis/connect the two parts allowing for an easy tool replacement. The system can be assembled on the UR 3, UR 5 or UR 10 collaborative robots and it includes both pneumatic and electric connection components useful to connect power sources between robot and tool. The whole system is a plug & play device with direct connection to the robot wrist and it can be used to transfer either pneumatic pressure and vacuum to the tool. Additional QC90-B spare parts are available upon request to create a more complex system where a robot interacts with several tools.
