Concrete operating principle of the embodiment of the present invention is as follows：
When needing to spray the first color, mechanical arm 1 arrives colour changing cleaning device 3 with atomizer 2, and atomizer 2 is with changing
Color cleaning device 3 is docked, that is, first accessed color changing valve 32, the second filling-valve 33, the first filling-valve 27 are opened, and are watched
Motor brake release is taken, starts to inject oil-gas storage cylinder 24 paint of the first color, after filling, first color changing valve
32nd, the second filling-valve 33, the first filling-valve 27 are turned off, and mechanical arm 1 drives atomizer 2 to depart from colour changing cleaning device 3, and paint valve
26 open, and promote piston to proceed by spraying by servomotor；After the paint in oil-gas storage cylinder 24 is finished, mechanical arm 1
Atomizer 2 is driven to access colour changing cleaning device 3 again, repeating action above, (the general conveying off time using two chassis is carried out
The filling of paint, is so not take up productive temp, because having safety in production gap between front and rear two chassis itself)；
When needing to spray second of color, the drive atomizer 2 of mechanical arm 1 to colour changing cleaning device 3 (under this action,
All valves are all to close), the first purge valve 28 and exhaust-valve 35 are first turned on, and servomotor band piston is by oil-gas storage cylinder
The paint of the first remaining color is drained in 24；Then the second purge valve 34, the first purge valve 28, the first filling-valve 27 are beaten
Open, cleaning solvent since the second purge valve 34 enter and this circuit is rinsed, waste liquid is expelled to waste liquid from exhaust-valve 35
Collection device 36, while the first shower nozzle purge valve 29 and the second shower nozzle purge valve 37 are opened, while the cleaning of shower nozzle 22 is carried out, rush
All valves are closed after the completion of washing；Then second of coloured paint can be filled, carry out the actions such as second of coloured paint of spraying.
Pass through more than design so that each pipeline of the invention greatly shortens, and in colour changing, it is necessary to cleaning pipeline compared with
It is few, therefore, the waste of cleaning solvent and paint is substantially reduced, and overall fitting can realize quick colour changing between each valve, it is actual
Using with the obvious advantage.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
Want made change, or be revised as the equivalent embodiment of equivalent variations, when still without departing from specification and illustrating covered spirit,
All should be within the scope of the present invention.
