Description

Paint spraying system {SYSTEM FOR SPRAYING PAINT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint spraying system, and more particularly, to a paint spraying system capable of automatically spraying paint on a painted surface of a small electronic component by a robot.

For example, various means are used in the case of coating work for spraying paint on the inside or outside of a coating body of a machine such as a mobile phone, an electronic notebook, or a plastic of an electronic product such as a PDA. In particular, in order to achieve good paint quality while performing a large amount of painting, a portable air spray gun is generally used.

The air spray gun continuously sprays the paint and compressed air, allowing the paint to be sprayed through the nozzle. Therefore, the paint is made in the direction toward the nozzle, so when painting a large amount of paint, the paints should be uniformly arranged, and the paint should be evenly distributed while moving the air spray gun from side to side. .

By the way, the coating work of the coating material as described above is made by hand, mass production is difficult, and continuous work was not made.

And, for example, when painting the corners of the coating, etc., it is difficult to spray the paint, and a large amount of coating failure may occur. In addition, since the paint is sprayed by hand, the thickness of the coating is not constant, it is not possible to obtain a constant coating quality, of course, it is impossible to spray the paint with the correct injection amount, the paint can be excessively sprayed, the paint consumption is large. This can also be another cause of failure.

In addition, since the operator directly manipulates the air spray gun, it is harmful to the human body, and work evasion occurs.

The present invention has been created in order to solve the above problems, it is possible to mass production by simply spraying the paint automatically, reduce the number of workers and working time, accurate injection is made to reduce the defect of the product The purpose of this invention is to provide a paint spray system that can reduce the consumption of paint.
