[0038] By using the water pump 27, the paint in the material storage tank 2 can be transported to the paint device main body 24, and then sprayed out by the spray head 25 at the paint device main body 24 to spray paint on the workpiece 16 in the placement seat 8. Subsequently, the output shaft of the second servo motor 21 drives the second threaded rod 20 to rotate, so that the threaded block 23 on the second threaded rod 20 can move back and forth, which is convenient for comprehensively moving and spraying the workpiece 16. At this time, the excess paint will flow into the interior of the collection box 4 along the chute 9 at the placement seat 8. At the same time, the guide plate 10 at the collection box 4 can guide the paint, which is convenient for the excess paint to enter the material storage tank 2 through the connecting pipe 5, so that the excess paint can be recycled and reused, saving costs and avoiding waste of paint. Then, the output shaft of the first servo motor 18 drives the first threaded rod 12 to rotate, so that the mounting block 13 on the first threaded rod 12 can drive the cross plate 14 to move back and forth, so as to use the coating brush 15 at the cross plate 14 to smooth the paint on the workpiece 16, which is convenient for subsequent UV curing;

[0039] By clamping the first filter plate 6 in front of the collection box 4 and then clamping the second filter plate 7 above the connecting pipe 5 to fix the first filter plate 6 and the second filter plate 7, the two filter plates can secondary filter the excess paint, so that the recycled paint can remove impurities and other residues, thereby improving the spraying quality of the paint device. Then, the rubber block 30 can be used to initially limit and fix the workpiece 16, and at the same time, two L-shaped plates 31 equipped with the first spring 32 and two positioning plates 34 equipped with the second spring 35 can elastically clamp the periphery of the workpiece 16, so as to ensure the stability during paint spraying.
