The NACHI Robot. Unfashionable? Think again
The sealing process is essentially a process of applying a form of air-tight, fluid-tight sealant or bonding chemicals to, say, a glass window so that it will adhere to an automobile's frame. All of this of course will be carried out in the assembly line as the frame progresses from one stage of production to another. If the process were to be carried out by humans, time would be an expensive consequence. Owing to the fact that human error can never be eliminated even in the best of conditions, a lot of residue (sealant, chemicals) may also result. Automating the process will eliminate resource wastage as well reduce the assembly time by a huge amount. This is why robotic systems are favoured so that the sealing process can be streamlined and perfect the application quality everytime the process is carried out.
The NACHI is an example of an industrial robot that can be deployed in sealing procedures. It is a typical six-axis robot, like most industrial robots, and has up to six-degress of freedom in terms of movement. These movements are possible because the robot has six independent joints in addition to cylindrical pistons that act as springs, thus enabling it to counter balance against gravity. This means the robot is able to lift heavy loads. The robot is also able to manipulate and place loads in any location in 3D-space(x-, y- and z- coordinates) as well as orient it in a specific fashion (roll, yaw, pitch for example).
