Problems solved by technology

[0003] The purpose of the present invention is to provide a space eight activity degree spraying robot, which can effectively solve the problems of traditional open-chain series robot mechanism, such as heavy weight, poor rigidity, large inertia, joint error accumulation, small working space of parallel robot mechanism, and inflexible movements, etc. It is especially suitable for spraying operations where both the first connecting rod and the second connecting rod are required to realize three-dimensional rotation, and the moving platform realizes two-dimensional rotation output

Abstract

The invention relates to an eight-spatial-degree-of-motion spraying robot, which comprises a first connecting rod, a second connecting rod, a moving platform, eight linear drivers and a machine frame. One end of the first connecting rod is connected to the machine frame through a first spherical pair, and the other end of the connecting rod is connected to the second connecting rod through a second spherical pair; the other end of the second connecting rod is hinged to the moving platform by a first Hooke; and the whole robot is driven by the eight linear drivers to output eight spatial degrees of motion. The spraying robot has the characteristics of flexible and accurate output track, high flexibility, large working space, easy operation and maintenance and is particularly suitable for two-dimensional rotation output spraying which needs the first connecting rod and the second connecting rod to do three-dimensional rotation and the moving platform to output three-dimensional rotation.

Description

technical field [0001] The invention relates to the field of spraying robots, in particular to a space eight-degree activity spraying robot. Background technique [0002] Spraying robot is an industrial robot that can automatically spray paint or spray other coatings. It can reduce the labor intensity of workers and prevent damage from chemical coatings. It is widely used in automobiles, instruments, electrical appliances, enamel and other craft production departments. Due to the limitations of its own structure, the traditional open-chain series robot mechanism has problems such as bulky mechanism, poor rigidity, large inertia, joint error accumulation, etc., and poor dynamic performance, which makes it difficult to meet the increasingly stringent high-speed and high-precision operation requirements. The parallel robot mechanism is a closed-loop mechanism with a moving platform and a fixed platform connected by at least two independent kinematic chains. The mechanism has tw...
