Spraying robot mechanism

Abstract

The invention relates to a spraying robot mechanism which comprises a waist swing mechanism, a shoulder swing mechanism, an elbow swing mechanism, a wrist swing mechanism, a spray gun base bending mechanism, a rack and a swing platform, wherein the waist swing mechanism, the shoulder swing mechanism and the elbow swing mechanism are connected in series and are chained between the wrist swing mechanism and the rack; the waist swing mechanism, the shoulder swing mechanism and the elbow swing mechanism are controlled by servo motors to swing in the working space; one end of the spray gun base bending mechanism is hinged with a wrist shaft, and the other end is hinged with the rack; and the rack is arranged on the swing platform. Because all the servo motors of the spraying robot mechanism are arranged on the rack and a rod piece can be manufactured into a light rod, the dynamic performance of the mechanism is good and can meet the requirements for high-speed and high-accuracy spraying. The mechanism provided by the invention is simple and compact in structure, reliable in operation, and convenient for transportation and installation, and is suitable for small-size common spraying operation and the spraying operation of large-size or heavy-size structures.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a spraying robot mechanism. Background technique [0002] Spraying robot is a kind of industrial robot for spraying operation, which can replace manual, complete various spraying operations in an environmentally friendly and efficient manner. It is widely used in automobile body spraying and other fields, and has become one of the most widely used industrial robots in the market. The existing mechanical structures of spraying robots mainly include parallelogram structure and side-mounted or pendulum structure, which have been widely used because of their larger working space and more flexible movements. However, due to the limitations of its own structure, this type of traditional open-chain series spraying robot mechanism requires the motor to be installed at the joint, resulting in problems such as heavy arm weight, poor rigidity, and large inertia. The dynamic performance of t...
