Having the potential to increase profits for producers around the world, the “Seventh Axis” is a phenomenon in the field of robotic automation. Robotics is seeing an increase in the use of “linear tracks”.
A linear transfer system known as a seventh axis is used to move robots along another linear (or seventh) axis. These devices, also known as “robot transfer units” or “linear transfer units“, allow robots to change the length of a linear track between different workstations and cells.
Instead of additional robots, a robot with a seventh axis can be easily moved to another work cell. Due to the need for human safety, this also makes it possible to place the robot outside the work area. With these advantages, the end user can save money and get a return on his investment more quickly.
There are numerous applications where a seventh axis would be beneficial, including painting, coating, welding, palletising, pick and place, transport and warehousing/logistics facilities. This is due to the fact that these robots can often complete tasks that would be difficult or even dangerous for humans.
Depending on requirements, 7th axis systems can be installed vertically or horizontally. In the warehouse or factory where they work, they can also be elevated to increase safety and create more floor space.
Even more versatility can be added by mounting smaller 7th axis systems on an AGV (automated guided vehicle). This increases an operation’s workflow and overall productivity by creating additional space for storage or other activities underneath.
A seventh axis can move through a variety of types of linear systems. Linear actuators, which are based on linear bearings driven by toothed belts, are one of the most popular technologies for moving smaller robots.
Aluminium guide rails are often used in 7th axis robots with plain bearings, which makes them substantially lighter than linear ball bearing systems. Linear ball bearings are recommended for larger robots with heavy cantilever loads. Care must be taken to prevent debris from entering the bearings in applications where there is the possibility of dirt, dust or metal shavings.
A typical robot arm could be made more effective and less expensive by adding a seventh axis. The workspace of any single robot is increased by an additional track. This additional axis could save you from having to use two robots that are being used inefficiently if you already have one robot that is not performing to its full potential and there is a shortage elsewhere.
