The coating flow of the spraying robot is the amount of coating delivered to each rotating cup in a unit time, also known as the spraying flow and paint output (rate). How to calculate? Robot manufacturer Xiao Bian will show you in detail.
In addition to the speed of the rotating cup, the coating flow rate is the two factors affecting the particle fineness. When other parameters remain unchanged, the lower the coating flow rate, the finer the atomized particles, but also increase the volatility of the solvent in the paint mist.
The high coating flow of the spraying robot will form a corrugated coating. At the same time, when the coating flow is too high to overload the rotating cup, the coating on the edge of the rotating cup thickens to a certain extent, resulting in that the groove lines on the rotating cup can not divert the coating, resulting in layered paint, resulting in uneven bubble or coating drop size.
The coating flow of each spray gun of the spraying robot is related to the diameter of the high-speed rotating cup and the density of the speed coating, and its upper limit is determined by the fineness of the atomization and the effect of the electrostatic coating. The practical experience shows that the coating should be input at a constant speed, and the fluctuation in a small range will not affect the quality of the coating.
In the actual spraying process, the spraying area of each rotating cup is different, and the coating flow is also different. In addition, due to the change of coating appearance, the coating flow of the rotating cup should also change. Take spraying the car body as an example. When spraying large areas such as door panels, the spraying amount is large, while spraying door posts and window posts, the spraying amount is small. During the spraying process, accurately control the spraying amount to ensure the coating quality and thickness, which is also one of the important measures to improve the coating utilization.
