Description

technical field [0001] The invention relates to the field of industrial assembly robots, in particular to a special SCARA robot for screw assembly. Background technique [0002] With the continuous advancement of "Made in China 2025", the level of industrial automation is rapidly improving, and more and more companies are using robots to replace traditional worker operations, which has significantly improved the production efficiency and economic benefits of the company. However, for robots, their own robustness and safety play a key role in the output of the production line. [0003] The traditional SCARA robot is a "three rotations and one translation" type of motion, and its translation motion is at the execution end of the robot. Due to factors such as force, it will affect the working accuracy and stability of the robot. At the same time, there are only two degrees of freedom in the horizontal direction to determine the coordinate points in the horizontal direction. Al...

[0003] The traditional SCARA robot is a "three rotations and one translation" type of motion, and its translation motion is at the execution end of the robot. Due to factors such as force, it will affect the working accuracy and stability of the robot.

At the same time, there are only two degrees of freedom in the horizontal direction to determine the coordinate points in the horizontal direction. Although the coordinate points in the horizontal direction can also be determined, the flexibility is not enough
