Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4As shown, a circuit board surface coating machine of this utility model includes a workbench 1, a mounting frame 2 on the workbench 1, an adjustment mechanism 3 connected to the mounting frame 2, a coating mechanism 4 connected to one side of the adjustment mechanism 3, and a first placement plate 5 and a second placement plate 6 below the coating mechanism 4; the coating mechanism 4 includes a mounting plate 41, a feeding pipe 42 and a mounting rod 43 connected to the mounting plate 41, the mounting plate 41 is connected to the adjustment mechanism 3, the feeding pipe 42 is provided with multiple discharge pipes 44, each discharge pipe 44 is connected to a spraying pipe 46 through a hose 45, the spraying pipe 46 is connected to the mounting rod 43 through a fixing member 47, and each discharge pipe 44 is provided with an adjustment valve 48.

[0025] In the technical solution of this utility model, multiple circuit boards are placed on both the first placement plate 5 and the second placement plate 6. The coating mechanism 4 can be moved by the adjustment mechanism 3 to facilitate coating of the circuit boards on the first placement plate 5 and the second placement plate 6. Multiple spray pipes 46 are provided on the mounting rod 43, and multiple spray pipes 46 can coat multiple circuit boards at the same time, which speeds up the work efficiency. The oil output of the spray pipe 46 can be controlled by the regulating valve 48 provided on the discharge pipe 44. The coating mechanism 4 can be moved to the top of one placement plate by the adjustment mechanism 3. When coating the circuit boards on the placement plate, the operator can load and unload materials on another placement plate, which further speeds up the work efficiency.

[0026] Specifically, a support frame 7 is provided on one side of the mounting frame 2, a storage tank 8 is provided on the support frame 7, a pump box 9 is provided on one side of the storage tank 8, and the pump box 9 is connected to the conveying pipe 42 through the conduit 10; the paint in the storage tank 8 can be sent into the conveying pipe 42 through the conduit 10 via the pump box 9.

[0027] The fixing component 47 includes a sliding plate 471, which is detachably connected to the spray tube 46. The sliding plate 471 is detachably connected to the mounting rod 43 via a screw 472. By removing the screw 472, the sliding plate 471 can slide on the mounting rod 43, which can adjust the spacing between adjacent spray tubes 46, making it convenient to coat circuit boards of different specifications and enhancing the applicability of the device.

[0028] like Figure 1 and Figure 3 As shown, multiple support plates 11 are provided on both the first placement plate 5 and the second placement plate 6. Limiting plates 12 are provided on both sides of the first placement plate 5 and the second placement plate 6. The limiting plates 12 are connected to one end of the electric telescopic rod 13.

[0032] Working principle: Multiple circuit boards are placed on both the first placement plate 5 and the second placement plate 6. The coating mechanism 4 can be moved by the adjustment mechanism 3 to facilitate coating of the circuit boards on the first placement plate 5 and the second placement plate 6. Multiple spray pipes 46 are set on the mounting rod 43, which can coat multiple circuit boards at the same time, thus speeding up the work efficiency. The oil output of the spray pipes 46 can be controlled by the regulating valve 48 set on the discharge pipe 44. The coating mechanism 4 can be moved to move above one placement plate by the adjustment mechanism 3. While coating the circuit boards on the first placement plate, the operator can load and unload materials on the other placement plate, further speeding up the work efficiency.
