Cleaning device for external valve pipeline of automatic spraying robot

Abstract

The invention discloses a cleaning device for an external valve pipeline of an automatic spraying robot, belonging to the pneumatic field or the hydraulic field. The external valve pipeline of the automatic spraying robot comprises a robot colour-changing valve, as well as a paint reflux pipeline and a paint pipeline which are connected with the robot colour-changing valve; the cleaning device comprises a first control valve, a second control valve, a third control valve, a fourth control valve, a fifth control valve, a solvent pipeline, a compressed air pipeline, an external colour pressure tank and a waste paint recovery bucket; the paint reflux pipeline is connected to the solvent pipeline via the third control valve and the first control valve; the paint reflux pipeline is connected to the compressed air pipeline via the third control valve and the second control valve; the paint pipeline is connected to the external colour pressure tank via the fourth control valve; and the paint pipeline is connected to the waste paint recovery bucket via the fifth control valve. The cleaning device disclosed by the invention is used for realizing a cleaning function for the external valve pipeline, has the characteristics of being convenient to operate, safe and reliable, low in cost, easy to maintain, long in service life and the like, effectively solves the problem that the external valve pipeline of the spraying robot in a spraying workshop of a factory is difficultly cleaned, and reduces wastes on a cleaning solvent, labour, line stopping time and the like simultaneously.

Description

technical field [0001] The invention relates to the fields of air pressure and hydraulic pressure, in particular to an external valve pipeline cleaning device of an automatic spraying robot. Background technique [0002] In the production process of auto body painting, the painting workshop often automatically sprays the car paint through a robot system. [0003] But sometimes, the spraying scope of the robot system is limited, and it is necessary to add an external color changing valve and pipeline to the robot system to form a small system for auxiliary spraying. After spraying with the small system, the small system needs to be cleaned, otherwise it will cause the problem that the robot system cannot work normally. [0004] At present, the small system requires the cooperation of more than two people to clean it. The robot must be in an atomized state during cleaning, which not only makes cleaning the small system difficult, but also if the personnel are not skilled, saf...
