Problems solved by technology

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

Abstract

The invention relates to a seven-mobility spraying robot mechanism, which comprises a first connection rod, a second connection rod, a movable platform, seven linear drivers and a frame. One end of the first connection rod is connected to the frame through a first spherical pair, the other end of the first connection rod is connected to the second connection rod through a first rotary pair, the other end of the second connection rod is connected to the movable platform through a second spherical pair, and the whole robot driven by the seven linear drivers in a joint mode can output movement with seven-mobility space. The seven-mobility spraying robot mechanism is flexible and accurate in output track, large in flexibility and working space, easy to operate and maintain and especially suitable for spraying operation occasions requiring both the first connection rod and the movable platform to achieve three-dimensional rotation output.

Description

technical field [0001] The invention relates to the field of spraying robots, in particular to a seven-activity-degree spraying robot mechanism. 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 ha...
