Embodiment 1

[0036] refer to figure 1 , a non-sputtering precision painting method, comprising the following steps:

[0037] S1: Carry out electrification treatment on the paint powder and the workpiece, and keep the electrification type of the paint opposite to the electrification type of the workpiece;

[0038] S2: the paint powder is sprayed out to coat the workpiece;

[0039] S3: while the paint coating is being applied, the paint powder deposited on the paint surface is preheated and solidified to form an orderly coating on the surface of the workpiece;

[0040] S4: After the final coating is completed, the main curing treatment is carried out, and the total curing heat is used for preheating the coating through heat conduction.

[0041] The method in this embodiment preheats and solidifies the deposited paint powder, so that individual coatings on the surface of the workpiece are formed one by one. When a single coating is formed, because its thickness is relatively thin, the gas h...

Embodiment 2

[0043] A non-sputtering precision painting system is disclosed in this embodiment. The painting system includes a painting platform 1, a loading plate 2 connected in rotation with the frame, a spray gun 3 and a heating plate 5. The painting platform 1 is provided with Working chamber, the working chamber of the working chamber coating platform 1 is divided into a spraying chamber 101 and a curing chamber 102 by the object carrier plate 2, and the sides corresponding to the object carrier plate 2 and the spray gun 3 or the heating plate 5 are respectively arranged for Mount the workpiece holder 6.

[0044] Further, the spray gun 3 and the mobile bracket 4 provided inside the spray chamber 101, the spray gun 3 is installed on the mobile bracket 4, the mobile bracket 4 can move inside the spray chamber 101, adjust the distance between the spray gun 3 and the workpiece, and improve the system suitability.

[0045] The nozzle of the spray gun 3 applies a high-voltage negative voltag...

Abstract

The invention discloses a non-sputtering precise paint spraying method and a paint spraying system, wherein the paint spraying method comprises the following steps: S1: electrifying the paint powder and the workpiece, keeping the charged type of the paint opposite to the charged type of the workpiece; S2: spraying the paint powder The workpiece is painted; S3: while the paint is being painted, the paint powder deposited on the paint surface is preheated and solidified to form an orderly coating on the surface of the workpiece; S4: after the final coating is completed, the main Curing treatment, through heat conduction, the total curing heat is used for preheating the coating. The non-sputtering precision painting method in the present invention preheats and solidifies the deposited paint powder, so that the surface of the workpiece forms a coating composed of multiple single coatings. layer, reducing the gas content in the film, so that the obtained coating has high density and good surface quality. The non-sputtering precision spraying system can implement the above method. The system has a compact structure and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a non-sputtering precise painting method and a painting system. Background technique [0002] Spray paint is a method in which a spray gun is dispersed into uniform and fine droplets by means of air pressure and applied to the surface of the object to be coated. Including air spraying, airless spraying and electrostatic spraying and other painting methods, among which electrostatic spraying technology is a non-sputtering, precise, directional and efficient spraying and filming technology. The droplets or powder of the sprayed material are charged, and under the action of electrostatic force, the sprayed material will fly to the workpiece to be filmed and deposited, and the target film layer will be formed after heating and curing. [0003] In the traditional electrostatic spraying process, due to the inclusion of air in the paint powder, the air overflows during the th...
