Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of 3D printing, in particular to a 3D printing glass surface spraying water-based paint device. BACKGROUND

[0002] With the continuous development of 3D printing technology, now it is possible to use 3D printing technology to make complex glass products. However, the surface of these products usually needs to be treated with decorative coatings such as spraying water-based paint to improve its aesthetic and durability; water-based paint is a coating that uses water as a diluent and does not contain organic solvents, does not contain benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic and non-irritating odor, harmless to human body, and does not pollute the environment, so it is used by people. Usually when using water-based paint, it is used in combination with a spraying device, which can effectively improve work efficiency;

[0003] Most of the existing 3D printing spraying devices lack a fixing mechanism for the sprayed object. During spraying, the object is usually placed on the surface of the workbench. Since the workbench moves back and forth during spraying, the sprayed object will shake during the movement, resulting in poor spraying results and thus reducing work efficiency, thereby reducing the use effect of the 3D printing spraying device. The 3D printing glass surface spraying water-based paint device needs to be finely calibrated to achieve good spraying effect, and improper operation can easily lead to low spraying precision or normal spraying;

[0004] In the prior art, a support assembly and a glass surface spraying device with publication number CN217615508U are disclosed, which comprises: a bottom plate, the upper ends of the left and right sides of the bottom plate are provided with telescopic rods, the upper ends of the left and right sides of the bottom plate are provided with mounting blocks, and the mounting blocks are located at the upper ends of the telescopic rods; rotating blocks, two rotating blocks are provided between the two mounting blocks, and a moving rod is provided between the two rotating blocks; and moving blocks, two moving blocks are provided, and the moving blocks are connected to the surface of the moving rod. The upper end of each moving block is provided with a suction cup on the front and rear sides. By adjusting the positions of the moving blocks and the suction cups by hand-tightening bolts according to the size of the glass, the positions of the two moving blocks are adjusted, and the glass is placed on the suction cups on the upper ends of the two moving blocks. Different specifications of the glass can be fixed; during the spraying of the glass, the motor drives the rotating rod to rotate, so that the glass can be rotated, facilitating the spraying of each position of the glass.

[0005] However, the above technical solutions have the following defects: first, the position adjustment of the moving block and the suction cup is inconvenient, and the position of the moving block and the suction cup needs to be adjusted manually by screwing the bolt, which may be time-consuming and labor-intensive; second, the size adaptability may not be strong enough, as the moving block and the suction cup of the device need to be adjusted manually, so it is not suitable for spraying processing of glass of different sizes; third, the fixing method of the glass may not be firm enough. The device uses a suction cup to fix the glass, and if the quality of the suction cup is not good or the suction cup does not completely fit the surface of the glass, it may cause the glass to move or fall off during spraying. In view of this, we propose a 3D printing glass surface spraying water-based paint device to solve the existing problems. SUMMARY
