Six-degree-of-freedom seven-rod series-parallel spraying robot

Abstract

The invention provides a six-degree-of-freedom seven-rod series-parallel spraying robot. According to the spraying robot, a driving rod, a linear driver and a support rod are connected with a rotating rack, a driving connecting rod is connected with the driving rod, the other end of the driving connecting rod is connected with the support rod, a movable arm table and the support rod are connected with the linear driver, a rotating arm is connected with the movable arm table, a swing arm is connected with the rotating arm, a sprayer table is connected to the swing arm, and a sprayer is connected to the sprayer table. Single series structure applied by the original robot is replaced by a series-parallel integral structure, so that the rigidity is high. A parallelogram four-linkage mechanism is applied to the six-degree-of-freedom seven-rod series-parallel spraying robot, so that accurate control is easy to realize. The six-degree-of-freedom seven-rod series-parallel spraying robot is suitable for manufacturing various mechanical arms and other engineering machinery.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a six-degree-of-freedom seven-bar series-parallel spraying robot. Background technique [0002] With the continuous development and improvement of modern spraying technology, the reform of spraying machine technology is also carried out all the time. Nowadays, the requirements for automated industrial production are gradually increasing, and the principles of safety production and environmental protection production are constantly implemented. The emergence of spraying robots has become inevitable. , and this high-tech spraying equipment can also meet these requirements of various workpieces very well. [0003] Spraying robot, also called painting robot, is an industrial robot that can automatically spray paint or spray other coatings. The painting robot is mainly composed of a robot body, a computer and a corresponding control system. Most of them adopt 5 or 6 degrees of ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing spraying robots adopt a six-degree-of-freedom series structure driven by servo motors. In this structure, all motors are installed at the arm joints, resulting in low overall rigidity of the robot, poor dynamic performance, large cumulative error of joints, large moment of inertia, and limited working range. Limited, these factors directly affect the spraying efficiency of the spraying robot, reduce the spraying quality, increase the spraying time, and prolong the spraying time, thus increasing the spraying cost
