Problems solved by technology

However, among them, the triple valve, solvent valve, and spray gun of the automatic machine are prone to blockage and failure; while the prior art directly uses solvents to flush the above-mentioned valves and spray guns, the cleaning effect is not ideal, and it is difficult to clean impurities such as paint slag therein. Defects such as paint slag, foreign matter, particles, solvent printing, and color mixing seriously affect the quality of spraying when it is used again, and it takes a lot of time and manpower to clean it again, which seriously affects the production rate.
[0003] At the same time, in the prior art, it is impossible to detect whether the repaired valves and spray guns are leaking or whether they are poorly opened and closed, and the quality after repairing cannot be known. After the trial operation, there may still be hidden dangers of quality defects, which may lead to secondary failures
In practice, the secondary faults caused by the clogging of automatic machine valves and spray guns account for more than 40% of the total faults of the automatic machine, which seriously affects the production utilization rate of the automatic machine, directly affects the production quality, and also brings hidden dangers to equipment safety

Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 Shown, the flushing and detection system of the automaton solvent valve of this embodiment, triple valve and spray gun include:

[0031] Compressed air supply device 20, this compressed air supply device can be any suitable device in the prior art;

[0032] The solvent supply device 30, in this embodiment, is a solvent pool for containing solvents, and a filter screen is arranged in the solvent pool to filter the returned solvent to realize recycling, and the placement position and structure of the filter screen can filter It is advisable to drop the dross and impurities in the backflow solvent. The solvent here is the solvent commonly used in the spraying process, such as the automatic color change solvent;

[0033] Diaphragm pump 80, which is connected to the solvent supply device 30, and is used to pump out the sol...

Abstract

The invention relates to a flushing and detecting system of a triple valve, a solvent valve and a spray gun of an automata, which comprises a compressed air supply device, a solvent supply device, a diaphragm pump and a plurality of pipelines, wherein the diaphragm pump is connected with the solvent supply device to pump out solvents in the solvent supply device with certain pressure; the pipelines are correspondingly connected to make the solvents and compressed air enter the solvent valve, the triple valve and the spray gun so as to clean the solvent valve, the triple valve and the spray gun, and after cleaning, the solvents flow back to the solvent supply device through a backflow pipe so as to be recycled. The flushing and detecting system of the solvent valve, the triple valve and the spray gun of the automata simulates the working principle of the automata to mix the solvents and the compressed air with certain pressure and further clean the valves and the spray gun with a good cleaning effect, and simultaneously whether a valve core is damaged or shifted or not is judged through observing the movement situation and the leakage condition of the valve core in air control.

Description

technical field [0001] The invention relates to a flushing and detection system of an automaton for automobile spraying, in particular to a flushing and detection system of an automaton triple valve, a solvent valve and a spray gun. Background technique [0002] The automatic machine is one of the key equipment in the automobile painting workshop, and its operation is directly related to the quality of spraying. However, among them, the triple valve, solvent valve, and spray gun of the automatic machine are prone to blockage and failure; while the prior art directly uses solvents to flush the above-mentioned valves and spray guns, the cleaning effect is not ideal, and it is difficult to clean impurities such as paint slag therein. Defects such as paint slag, foreign matter, particles, solvent printing, and color mixing seriously affect the quality of spraying when it is used again, and it takes a lot of time and manpower to clean it again, which seriously affects the product...
