What are the components, functions and advantages of a six axis joint robot?
A common six axis joint robot has built in six servo motors, which directly drive the rotation of the six joint axes through the reducer and synchronous belt pulley. Six axis industrial robots generally have 6 degrees of freedom, including rotation (s axis), lower arm (L axis), upper arm (U axis), wrist rotation (r axis), wrist swing (b axis) and wrist rotation (t axis); The 6-DOF motion of the end is realized by the synthesis of 6 joints, which has many advantages such as high flexibility, large load and high positioning accuracy.
The six axis joint robot can be used for automatic assembly, painting, handling, welding and post-processing. It can be repositioned with a straight spool, and can make flexible actions like human beings. The robot can execute the instructions of the operator.
Functions of six axis:
First axis: the first axis is the position linking the chassis, and also the bearing and core position. It carries the weight of the whole robot and the large horizontal swing of the robot.
The second axis: an important axis for controlling the swing and expansion of the robot.
The third axis: the third axis is also the first axis that controls the robot to swing back and forth. However, the swing amplitude is much smaller than the second axis. However, this is also the basis for the arm extension of the six axis robot.
The fourth axis: the fourth axis controls the upper arm to rotate 180°freely, it is equivalent to the human forearm.
The fifth axis: the fifth axis is very important. After you have almost adjusted the position, you need to accurately position the product. You need to use the fifth axis, which is equivalent to the wrist of a person.
The sixth axis: when you position the fifth axis on the product, you need to use the sixth axis for minor changes. The sixth axis is equivalent to a turntable that can rotate 360°horizontally. The product can be more accurately positioned.
Advantages of six axis robot
1. High degree of freedom, 6-axis, suitable for almost any trajectory or angle of work;
2. It can be programmed freely to complete fully automatic work, improve production efficiency and control error rate;
3. Functional features, easy operation, flexible and quick replacement between different workpieces;
4. It has high accessibility and can make its hands work in the enclosed space, while the rectangular coordinate robot can not do such work;
5. Instead of many complex jobs that are not suitable for human completion and harmful to health.
