A sprayer is a device used to coat a surface, usually used in coating processes in industrial production. The sprayer achieves uniform coverage of the coating by spraying the paint onto the surface of the object to be coated. The sprayer can choose different spraying methods and spraying equipment according to different coating requirements and paint properties. The main components of the sprayer include a spray gun, a nozzle, a compressed air system, a paint supply system, a bracket and a guide rail. The paint is sprayed out through the spray gun, the nozzle controls the spray direction and uniformity of the paint, the compressed air system provides the air pressure required for spraying, the paint supply system is used to transport the paint to the spray gun, and the guide rail on the top of the bracket is used to drive the spray gun to move.

When spraying, one side is sprayed first, and then it is manually turned over to spray the other side. Manual turning takes a long time, is troublesome, and has low efficiency. Therefore, this application provides a high-efficiency automatic turning sprayer to meet the needs. Utility Model Content

[0039] like Figure 6 As shown, in this embodiment, a card slot 347 is opened on the surface of the positioning rod 346. After the circuit board is connected to the positioning rod 346 through the mounting hole, the mounting hole of the circuit board can be snapped into the card slot 347. When the circuit board is flipped downward, the card slot 347 can improve the stability of the circuit board in the vertical direction, prevent the circuit board from falling downward, and make the circuit board more stable during spraying.

[0040] like Figure 4 and Figure 6 As shown, in this embodiment, an ejection mechanism 4 is provided on the surface of the connecting bar 345, and the ejection mechanism 4 includes a second electric push rod 41 fixed at the bottom of the connecting bar 345, and the second electric push rod 41 is connected to an external controller, and the start and stop of the second electric push rod 41 are controlled by the controller.

The square plate 342 slides on the surface of the guide rod 344. The square plate 342 drives the connecting strip 345 to move. The connecting strip 345 drives the positioning rod 346 to move. The card slot 347 of the positioning rod 346 is connected to the mounting hole of the circuit board, so as to fix the circuit board.

[0045] Start the sprayer body 2 on the top of the base 1, and the conformal coating is sprayed out from the spray gun of the sprayer body 2. The conformal coating is sprayed on the surface of the circuit board. When one side of the circuit board is sprayed, start the servo motor 32. The servo motor 32 drives the housing 341 to rotate 180 degrees clockwise. The housing 341 drives the circuit board to rotate 180 degrees clockwise through the connecting strip 345 and the positioning rod 346. Then, start the sprayer body 2 again to spray the other side of the circuit board.

[0046] After both sides of the circuit board are sprayed, the servo motor 32 is started, and the servo motor 32 rotates 180 degrees counterclockwise to reset the circuit board, and then the first electric push rod 33 is started, and the first electric push rod 33 drives the shell 341 to move toward each other until the tension spring 343 inside the shell 341 is in an unstretched state. At this time, the second electric push rod 41 is started, and the second electric push rod 41 drives the circular plate 42 to move upward, and the circular plate 42 drives the ejection block 43 to move upward, and the ejection block 43 ejects the top of the connecting strip 345 and abuts on the surface of the mounting hole of the circuit board, and the mounting hole of the circuit board is pushed out of the card slot 347 through the ejection block 43, and then the circuit board is removed from the positioning rod 346 upward, and finally the second electric push rod 41 drives the circular plate 42 to move downward, and the circular plate 42 drives the ejection block 43 to move downward, and the ejection block 43 is reset.
