Where is the strength of the seven-axis industrial robot?
With the gradual maturity of the industrial robot industry, seven-axis robots have become a breakthrough goal for many companies and are also regarded as a sign of high-end industrial robots. Compared with the very common six-axis industrial robot, what are its advantages?
At present, conventional six-axis robots can not only pass through the x, y, and z axes, but also each axis can rotate independently. Compared with five-axis robots, the biggest difference between them is that they have an additional axis that can rotate freely. body.
The seven-axis robot is also called a redundant robot. Compared with the six-axis robot, it has more flexibility and can adapt to more special scenarios. At present, it is mainly in the 3C industry.
Compared with the six-axis robot, it can solve the kinematics pain points of the robot and realize the movement path planning that the six-axis robot cannot complete, especially the end part, which can change its position. At the same time, the seven-axis robot can realize the redistribution of joint torque and use its structure to achieve more dynamic performance. And different from the equal force distribution of the six-axis robot, the seven-axis robot can realize the control of each axis according to the algorithm, which is more reasonable. This structure also increases its fault tolerance. After a traditional six-axis robot fails in one axis, the entire machine cannot work, while a seven-axis robot can adjust its own parameters and redistribute to ensure normal operation.
