It plays a crucial role in PCB manufacturing, ensuring that the circuit boards remain clean before soldering, assembly, and other processes, preventing contamination that could affect product quality. An existing PCB board cleaning device with publication number CN220195720U includes: a tank with a feeding channel; a conveying mechanism disposed within the tank, comprising baffles and rollers arranged within the tank, with gaps between the rollers; the rollers include a first roller and a second roller, arranged vertically; a conveying channel between the first and second rollers for the PCB board to pass through, the conveying channel being adapted to the feeding channel; baffles disposed within the gap, with their top surfaces flush with the top surfaces of the second rollers; and a spraying mechanism disposed above the conveying mechanism, used to spray water onto the PCB board. By installing baffles between the second row of rollers, with the top surface of the baffles flush with the top surface of the second row of rollers, small-sized PCB boards can be cleaned, avoiding problems such as boards falling or jamming during transport, thus improving the cleaning efficiency of PCB boards and enhancing product quality.

[0003] However, in the above solution, the spraying range of the spraying mechanism is limited because the position of the spraying mechanism is not easily adjusted by the staff when spraying the PCB board, and it cannot cover the entire surface of the PCB board, resulting in some areas of the PCB board not being thoroughly cleaned. Utility Model Content

[0004] The main purpose of this utility model is to provide a PCB board cleaning and conveying device, which can effectively solve the problem that when the spray mechanism in the PCB board cleaning device in the background art sprays the PCB board, the position of the spray mechanism is not easy to be adjusted by the staff, resulting in a limited spray range of the spray mechanism, which cannot cover the entire surface of the PCB board, resulting in some areas of the PCB board not being thoroughly cleaned.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PCB board cleaning and conveying device includes a frame, a conveyor belt is provided between the two sides of the inner wall of the frame, and a sliding groove is provided through the two sides of the inner wall of the frame. Several sliders are slidably arranged in the two sliding grooves, and a spray pipe is fixedly installed between the opposing sliders.

[0007] Each of the sliders located on one side is fixedly equipped with a water inlet pipe, and one end of each water inlet pipe extends into the inner cavity of the corresponding spray pipe.

[0008] Preferably, a lifting frame is slidably installed through the top of the frame, a lifting plate is fixedly installed on the upper surface of the lifting frame, and movable plates are fixedly installed on both sides of the lower surface of the lifting frame.

[0011] Preferably, a slide bar is fixedly installed on the other side of the top of the connecting frame, and the lifting plate is slidably disposed on one side of the slide bar.

[0012] Preferably, both of the slides are provided with limiting components for limiting the slider position.

[0013] Preferably, the limiting component includes two limiting grooves, which are respectively opened on both sides of the inner wall of the corresponding slide groove. Several limiting blocks are slidably arranged in each of the two limiting grooves, and one side of each limiting block is fixedly connected to the corresponding slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The staff places the PCB board on the surface of the conveyor belt, and then starts the conveyor belt to transport the PCB board. Then the staff connects the water inlet pipe to the output end of the water supply equipment through a hose. Then the staff supplies water into the water inlet pipe, so that the water flows through the spray pipe to spray the PCB board. The staff controls the slider to move, so that the spray pipe in the middle does not move, and the other spray pipes move relative to each other, thereby increasing the spray range of the spray pipe, avoiding the formation of spray dead corners, so that every part of the PCB board can be thoroughly cleaned.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5 As shown, a PCB board cleaning and conveying device includes a frame 1, a conveyor belt 2 is arranged between the two sides of the inner wall of the frame 1, and a sliding groove 3 is opened through the two sides of the inner wall of the frame 1. Several sliders 4 are slidably arranged in the two sliding grooves 3, and spray pipes 5 are fixedly installed between the opposing sliders 4.

[0024] Each slider 4 located on one side has a water inlet pipe 6 fixedly installed on one side, and one end of each water inlet pipe 6 extends into the inner cavity of the corresponding spray pipe 5.

[0025] The staff places the PCB board on the surface of the conveyor belt 2, then starts the conveyor belt 2 to transport the PCB board. The staff then connects the water inlet pipe 6 to the output end of the water supply equipment through a hose, and supplies water into the water inlet pipe 6, so that the water flows through the spray pipe 5 to spray the PCB board. The staff controls the slider 4 to move, so that the spray pipe 5 in the middle does not move, while the other spray pipes 5 move relative to each other, thereby increasing the spray range of the spray pipe 5, avoiding spray dead corners, and ensuring that every part of the PCB board is thoroughly cleaned.

[0026] In another embodiment of this utility model, a lifting frame 7 is slidably disposed through the top of the frame 1, a lifting plate 8 is fixedly installed on the upper surface of the lifting frame 7, and movable plates 9 are fixedly installed on both sides of the lower surface of the lifting frame 7. Guide grooves 10 are opened through the opposite side surface of the two movable plates 9, and each spray pipe 5 is slidably disposed in the corresponding guide groove 10.

[0027] The staff controls the lifting frame 7 to move, which in turn moves the moving plate 9. Under the pushing action of the inner wall of the guide groove 10 on the body of the spray pipe 5, the middle spray pipe 5 does not move, while the other spray pipes 5 move relatively.

[0028] In another embodiment of the present invention, a connecting frame 11 is fixedly installed in the middle of the upper surface of the frame 1, and a lead screw 12 is rotatably installed on one side of the top of the connecting frame 11. The lifting plate 8 is threaded on one side of the lead screw 12.

[0029] A motor 13 is fixedly installed on one side of the upper surface of the connecting frame 11, and the upper end of the lead screw 12 passes through the connecting frame 11 and is fixedly connected to the output shaft end of the motor 13.

[0030] A slide rod 14 is fixedly installed on the other side of the top of the connecting frame 11, and the lifting plate 8 is slidably disposed on one side of the slide rod 14.

[0031] The operator starts the motor 13, which causes its output shaft to drive the lead screw 12 to rotate. The rotating lead screw 12 drives the lifting plate 8 to move along the slide bar 14 by screwing in. The moving lifting plate 8 can drive the lifting frame 7 to move.

[0032] In another embodiment of this utility model, each of the two slide grooves 3 is provided with a limiting component 15 for limiting the slider 4.

[0033] The limiting component 15 includes two limiting grooves 1501, which are respectively opened on both sides of the inner wall of the corresponding slide groove 3. Several limiting blocks 1502 are slidably arranged in both limiting grooves 1501, and one side of each limiting block 1502 is fixedly connected to the corresponding slider 4.

[0034] Under the limiting action of the limiting groove 1501 on the limiting block 1502, the slider 4 can be limited, preventing the spray pipe 5 from detaching.

[0035] Working principle of this PCB board cleaning and conveying device:

[0036] During use, the operator places the PCB board on the surface of the conveyor belt 2, then starts the conveyor belt 2 to transport the PCB board. The operator then connects the water inlet pipe 6 to the output end of the water supply equipment via a hose, and supplies water into the water inlet pipe 6. The water flows through the spray pipes 5 to spray the PCB board. The operator controls the slider 4 to move, so that the middle spray pipe 5 remains stationary while the other spray pipes 5 move relative to each other, thereby increasing the spray range of the spray pipes 5, avoiding spray dead zones, and ensuring that every part of the PCB board is thoroughly cleaned.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
