The paint spraying machine is actually a spraying machine, which uses the same principle to disperse the paint into mist and spray it on the surface of the object to be coated. Paint spraying machine is a common name for spraying machine. There are many types of paint spraying machines and accessories: spray guns, glue applicators, arc spray paint machines, high-pressure airless paint spray machines, two-component paint spray machines, paint spray guns, air spray guns, pneumatic double-diaphragm pumps, automatic stirring pressure delivery barrels, electrostatic Powder spraying equipment, new powder spraying equipment, flame powder spraying system and so on. Some outdated equipment is gradually replaced by new spraying machines. Take the current new spraying machine as an example, it is qualitatively different from the traditional painting method in the past. At present, the circuit board needs to be cleaned and dried before painting, and then it can enter the painting process. However, in the process of painting, circuit boards that are not completely dried are often encountered, which will easily increase the solidification time of the sprayed paint. Since both sides of the circuit board need to be painted, this will reduce production efficiency.

Preferably, the electric heating tube, the motor and the high-pressure pump are all electrically connected to the control panel.

Preferably, there are three high-pressure spray heads in total, and the three high-pressure spray heads are respectively installed under the spray bar.

Preferably, several limit blocks are provided in total, and the several limit blocks are evenly installed on the conveyor belt.

Preferably, an oil filling hole is provided on the top of the paint tank.

Preferably, the high-pressure pump is connected to the spray rod through a pipeline, and a control valve is arranged on the connecting pipeline.

Compared with the prior art, the beneficial effect of the utility model is: the equipment is equipped with a drying device, which is located at the starting end of the conveyor belt, and the circuit board is preheated and dried by the drying device before painting, and then enters Spray paint in the spray booth, so that the incompletely dried circuit board can be dried twice, and the circuit board can also be preheated through the drying device, so that the paint can be sprayed on the circuit board more easily, and at the same time, the paint can be reduced. The curing time of the material is improved, which improves the production efficiency.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1 and Fig. 2, a kind of embodiment that the utility model provides: a kind of high-efficiency painting device for making circuit boards, comprises fuselage 10, four corners of fuselage 10 bottoms are respectively fixed with traveling wheels 15, and One side of the fuselage 10 is provided with a control panel 12, and the inside of the fuselage 10 is equipped with a motor 11, a high-pressure pump 13 and a paint tank 14, and the high-pressure pump 13 is located between the motor 11 and the paint tank 14, and the top of the fuselage 10 is connected The inside of the workbench 1 is equipped with a transmission shaft 2, a limit block 8, a driving shaft 9 and a conveyor belt 16, and the conveyor belt 16 is wrapped around the outside of the transmission shaft 2 and the driving shaft 9, and the transmission shaft 2 is located on one side of the driving shaft 9. The bit block 8 is installed on the conveyor belt 16, the top of the workbench 1 is provided with a spray booth 3 and a drying room 6, and the drying room 6 is located on one side of the spray booth 3, and the inside of the spray booth 3 is installed below the spray bar 4 A high-pressure shower head 5 is connected, and an electric heating tube 7 is fixed on the inner top of the drying chamber 6 .
