With the rapid development of intelligent technology, spraying robots have been widely used in various industries. The spraying process and suitable products of spraying robots are different. Below, the editor will introduce three spraying methods of spraying robots.

1. Electrostatic spraying method: Among these three spraying methods, electrostatic spraying is the most widely used spraying method for spraying robots. Its spraying principle is mainly based on the grounded sprayed workpiece as the anode, while the coating atomizer is connected to a negative high voltage as the cathode, so that the atomized coating particles are charged and adsorbed on the surface of the workpiece through electrostatic action. The electrostatic spraying method used by spraying robots is often used for metal spraying or spraying workpieces with complex coating structures.

2. Air spraying method: The air spraying method of the spraying robot mainly uses the airflow of compressed air, which flows through the nozzle hole of the spray gun to form negative pressure. Then, under the action of negative pressure, the paint is sucked in and sprayed evenly on the surface of the workpiece through the spray gun, forming a smooth coating. The air spraying method of painting robots is generally used for painting workpieces such as furniture and electronic casings. And due to the low production cost of air spraying method, it is still widely used among the three spraying methods of spraying robots.

3. High pressure airless spraying method: Compared with air spraying, the high-pressure airless spraying method of spraying robots is a more advanced spraying method. It mainly uses a booster pump to pressurize the paint to a high pressure of 6-30MPa, and then sprays it through the fine pores of the spray gun to atomize the paint. The high-pressure airless spraying method has high coating utilization and spraying production efficiency, and the quality of workpieces sprayed by spraying robots using high-pressure airless spraying method is significantly better than that sprayed by air spraying method. The high-pressure airless spraying method is generally suitable for spraying workpieces with high requirements for coating quality.
