[0004] In daily work, when equipment is spraying treatment agents on circuit boards, it is difficult for general equipment to adjust the spraying height, resulting in difficulty in fully spraying the treatment agent on the surface of the circuit board. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that it is difficult for equipment to fully spray circuit boards of different sizes, and to propose a circuit board surface treatment agent spraying mechanism.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a circuit board surface treatment agent spraying mechanism, comprising a connecting frame, a bracket, a conveyor belt and a power device, the bracket is fixedly connected to the lower surface of the connecting frame, the conveyor belt is located inside the connecting frame, a power device is provided on the side of the connecting frame, a spraying device is provided on the surface of the connecting frame, the spraying device comprises a frame and a spray plate, the frame is fixedly connected to the side of the connecting frame, the spray plate is located inside the connecting frame, and a nozzle is fixedly connected to the lower surface of the spray plate.

[0007] Furthermore, a telescopic tube is fixedly connected to the upper surface of the spray plate, and a cylinder is fixedly connected to the upper surface of the frame. By setting the telescopic tube, the spray plate can be connected to the water tank, thereby reducing the difficulty of connecting the spray plate to the water tank when the equipment is in use, resulting in the spray plate being unable to communicate with the water tank when moving up and down.

[0008] Furthermore, one end of the cylinder is fixedly connected to the upper surface of the spray plate, and a water tank is fixedly connected to the upper surface of the frame. The cylinder is provided to facilitate the movement of the spray plate.

[0009] Furthermore, a pump is fixedly connected to the upper surface of the water tank, and a water inlet pipe is fixedly connected to the side of the water tank. The pump is provided to facilitate pouring the liquid inside the water tank into the spray plate for spraying.

[0010] Furthermore, a cleaning device is provided at one end of the connecting frame, and the cleaning device includes a connecting block and a connecting arm, the connecting block is fixedly connected to the side of the connecting frame, the connecting arm is arranged on the upper surface of the connecting block, one end of the connecting arm is fixedly connected to a connecting plate, the surface of the connecting plate is fixedly connected to cleaning cotton, the upper surface of the connecting block is fixedly connected to a positioning rod, the connecting arm is arranged on the surface of the positioning rod, a card slot is provided on the side of the positioning rod, the surface of the connecting arm is rotatably connected to a card plate, and the card plate is clamped with the inside of the card slot. By arranging the cleaning cotton, the surface of the conveyor belt can be cleaned, which reduces the situation that the surface of the conveyor belt is easily adsorbed with liquid when the equipment is in use, causing the circuit board placed on the surface of the conveyor belt to be contaminated.

[0011] Furthermore, one end of the clamping plate is clamped with the side surface of the positioning rod, and a protrusion is fixedly connected to the upper surface of the connecting arm.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, by setting a spraying device, when the equipment is in use, the user starts the cylinder, and then the cylinder moves, driving the spray plate to move. When the spray plate moves, it drives the telescopic tube to move and connect with the water tank. Then the pump runs to let the water in the water tank enter the spray plate, and then the spray plate sprays through the nozzle. By setting the spraying device, the circuit boards on the surface of the conveyor belt are effectively sprayed, which plays a role in spraying and cleaning the circuit boards on the surface of the conveyor belt. When spraying the treatment agent on the surface of the circuit board, it is difficult for general equipment to adjust the height of the spray, which makes it difficult for the equipment to fully spray the treatment agent on the surface of the circuit board. The spraying device can adjust the height of the spray plate and spray the surfaces of circuit boards of different sizes, thereby improving the practicality of the equipment.

[0015] 2. In the utility model, a cleaning device is provided. When the equipment is in use, the user moves the card plate, and the card plate rotates on the surface of the connecting arm. When the card plate moves, the spring is displaced and deformed to generate elastic force, and the card plate moves out of the inside of the card slot. Then the connecting arm loses its restraint, and the connecting arm is pulled to move, driving the connecting plate and the cleaning cotton to move out of one end of the connecting frame. By providing the cleaning device, the surface of the conveyor belt is effectively cleaned, which plays a role in cleaning the surface of the conveyor belt, reducing the risk of the spraying device easily spraying liquid on the surface of the conveyor belt when the equipment is in use, resulting in the circuit board being easily placed on the surface of the conveyor belt with liquid on the surface after the equipment conveyor belt circulates one circle, causing pollution to the circuit board. The cleaning device can clean the excess liquid on the surface of the conveyor belt, thereby improving the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Specifically, a telescopic tube 54 is fixedly connected to the upper surface of the spray plate 52 , and a cylinder 55 is fixedly connected to the upper surface of the frame 51 .

[0025] In this embodiment, the telescopic tube 54 is provided to connect the spray plate 52 to the water tank 56, thereby reducing the problem that the spray plate 52 is difficult to connect to the water tank 56 when the equipment is in use, resulting in the spray plate 52 being unable to communicate with the water tank 56 when moving up and down.

[0026] Specifically, one end of the cylinder 55 is fixedly connected to the upper surface of the spray plate 52 , and a water tank 56 is fixedly connected to the upper surface of the frame 51 . The cylinder 55 is provided to facilitate the movement of the spray plate 52 .

[0027] Specifically, a pump 57 is fixedly connected to the upper surface of the water tank 56, and a water inlet pipe 58 is fixedly connected to the side of the water tank 56. The pump 57 is provided to facilitate pouring the liquid inside the water tank 56 into the spray plate 52 for spraying.

[0028] In this embodiment: a cleaning device 6 is provided at one end of the connecting frame 1, and the cleaning device 6 includes a connecting block 61 and a connecting arm 62. The connecting block 61 is fixedly connected to the side of the connecting frame 1, and the connecting arm 62 is arranged on the upper surface of the connecting block 61. One end of the connecting arm 62 is fixedly connected to a connecting plate 63, and the surface of the connecting plate 63 is fixedly connected to a cleaning cotton 64.

[0029] In this embodiment: by providing cleaning cotton 64, the surface of the conveyor belt 3 can be cleaned, which reduces the situation where the surface of the conveyor belt 3 is easily adsorbed with liquid when the equipment is in use, causing the surface of the conveyor belt 3 to be contaminated by the circuit boards placed on it.

[0030] Specifically, one end of the clamping plate 67 is clamped with the side surface of the positioning rod 65, and a protrusion 68 is fixedly connected to the upper surface of the connecting arm 62.

The spraying device 5 can adjust the height of the spray plate 52 to spray the surfaces of circuit boards of different sizes, thereby improving the practicality of the equipment.

[0033] When the device is in use, the user moves the card plate 67, and then the card plate 67 rotates on the surface of the connecting arm 62.

By setting up the cleaning device 6, the surface of the conveyor belt 3 is effectively cleaned, which plays a role in cleaning the surface of the conveyor belt 3, reducing the risk of the spraying device easily spraying liquid on the surface of the conveyor belt 3 when the device is in use, resulting in the circuit board being easily placed on the surface of the conveyor belt 3 with liquid on the surface after the conveyor belt 3 circulates one circle, causing pollution to the circuit board.
