Rotary table upright type five-freedom-degree mixed-connecting spray painting robot

Abstract

The invention relates to a rotary table upright type five-freedom-degree mixed-connecting spray painting robot which is large in work space and has certain flexibility. The rotary table upright type five-freedom-degree mixed-connecting spray painting robot comprises a foundational series-connection movement unit and a tail end parallel-connection spray painting operation unit. The foundational series-connection movement unit has two rotation freedom degrees and a movement freedom degree and is composed of a machine body rotation joint, a machine body lifting movement joint and a horizontal rotation joint. The tail end parallel-connection spray painting operation unit has two movement freedom degrees and is a plane parallel-connection mechanism composed of a large arm, a small arm, a connecting rod, a crank, a movable platform and the like. The rotary table upright type five-freedom-degree mixed-connecting spray painting robot has the advantages of being wide in work range, small in number of driving joints, compact in structure, easy to manufacture, convenient to control, capable of enabling the modularization to be achieved easily and the like.

Description

technical field [0001] The invention belongs to the fields of mechanical manufacturing design and automobile painting, and specifically relates to a turntable column type five-degree-of-freedom hybrid spraying robot with a large working range and certain flexibility and flexibility. Background technique [0002] With the rapid development of my country's automobile industry, expanding production scale, increasing automobile output, and improving quality levels all put forward higher requirements for automobile painting technology, and robot spraying, as a key link in automobile painting production, has become an important part of the improvement process. Production efficiency is an important technical means to ensure the quality of production. Robotic spraying has more than 30 years of research and development history in foreign countries. Developed countries have widely used spraying robots in the automobile production industry, and have rich experience in the research and d...

AI Technical Summary

Problems solved by technology

[0009] However, at present, most of my country's automobile manufacturing industry is still using automatic spraying machines to complete the spraying work. Most of the existing automatic spraying machines have disadvantages such as low spraying efficiency, low flexibility, single spraying trajectory, low flexibility, and waste of paint. , has been unable to adapt to the current flexible order production mode of automobile production, which seriously restricts the development of the current automobile industry

Although some invention patents have provided some mechanical forms and examples of spraying robots, it is undeniable that some of the spraying robots provided by these patents have the disadvantages of poor flexibility and insufficient flexibility; The spraying robot inevitably has problems such as too many redundant drives, complex structure, and difficult control.
