Spraying robot control system capable of automatically controlling spraying thickness

Abstract

The invention discloses a spraying robot control system capable of automatically controlling spraying thickness. The spraying robot control system comprises a mechanical main arm, a rotary base positioned at the bottom end of the mechanical main arm, a two-section mechanical arm positioned at the top of the mechanical main arm and a mechanical wrist movably connected to the front end of the two-section mechanical arm. A detection probe is fixedly arranged at the top end of the mechanical wrist, a conveying pipe is arranged at the front end of the mechanical wrist in a communicating manner, a duckbilled spray head is fixedly arranged at the front end of the conveying pipe, and coating spray holes communicating with the conveying pipe are formed in the front end of the duckbilled spray head.Through an arranged spray hole control structure, opening and closing of each spray hole can be controlled, coating is saved, and the spraying precision is improved. Through an arranged cleaning structure, a coating blowing nozzle can blow the dispersed part of coating sprayed out of the duckbilled spray head to a workpiece, dispersion of the coating is reduced, a dust removal spray head can blowaway powder dust on the surface of the workpiece, then the dust is wiped through a sponge wiper, and the coating can be better attached to the surface of the workpiece.

Description

technical field [0001] The invention relates to spraying equipment, in particular to a spraying robot control system for automatic control of spraying thickness. Background technique [0002] Spraying robot, also known as 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. The hydraulically driven painting robot also includes hydraulic oil sources, such as oil pumps and oil tanks. And motors, etc., the arm has a large movement space, and can do complex trajectory movement, and can move flexibly. The wrist of the more advanced painting robot adopts a flexible wrist, which can be bent in all directions and rotated. Its action is similar to that of a human. The wrist can be easily inserted into the workpiece through a small hole, and the inner surface can be sprayed. The sensor can be used to detect the workpiece body and paint sur...

Problems solved by technology

[0003] However, in actual implementation, it is impossible to control the switch of each spray hole, and it is impossible to adjust the area of ​​the sprayed paint from the nozzle, resulting in waste of paint, easy to overlap, and difficult to control the thickness of the spray. Secondly, the surface of the workpiece needs to be cleaned, otherwise the paint It is easy to fall off after drying, and it is easy to disperse after the nozzle is atomized, which is difficult to control and will be adsorbed to the surface of the machine, affecting the appearance
