Six-freedom-degree eight-rod series-parallel connection spraying robot

Abstract

The invention provides a six-freedom-degree eight-rod series-parallel connection spraying robot. A first driving rod, a second driving rod and a supporting rod of the spraying robot are connected with a rotating machine frame. A first driving connection rod and a second driving connection rod are connected with the first driving rod and the second driving rod respectively. A moveable arm table is connected with the supporting rod and the second driving connection rod. A rotating arm is connected with the movable arm table. A swing arm is connected with the rotating arm. A spraying head table is connected to the swing arm. A spraying head is connected to the spraying head table. According to the six-freedom-degree eight-rod series-parallel connection spraying robot, a series-parallel connection integrated structure is adopted for replacing a single series connection structure of an existing robot, and rigidity is high; and a parallelogram link mechanism is applied to the six-freedom-degree eight-rod series-parallel connection spraying robot, accurate control can be achieved easily, and the six-freedom-degree eight-rod series-parallel connection spraying robot is suitable for manufacturing various mechanical arms and other engineering machines.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a six-degree-of-freedom eight-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
