Manual wiping is inefficient and greatly affected by the operator's skill level and working condition, making it difficult to guarantee consistent cleaning results. During the wiping process, uneven force or improper selection of wiping tools can easily scratch the circuits and components on the PCB surface, leading to an increase in product defect rate. For some precision PCBs, manual operation is even more difficult to meet their strict cleanliness requirements. Therefore, the above problems need to be solved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a PCB board surface cleaning device, comprising a support frame 1, on which a belt conveyor 3 is mounted. The belt conveyor 3 ensures the PCB board remains stable during transport, allowing the cleaning component to clean the PCB board surface evenly and comprehensively. One end of the belt conveyor 3 is equipped with a drive motor 5 for driving the belt conveyor 3, facilitating automated operation. Two mounting blocks are located on both sides of the belt conveyor 3, welded to the top surface of the support frame 1. Two servo motors are mounted on each mounting block, and the output ends of the two servo motors are coaxially connected to lead screws 4. The lead screws 4 allow the cleaning component to be accurately adjusted to a suitable height, ensuring a proper distance between the cleaning component and the PCB board surface. A support block is threaded onto the lead screw 4, and a guide rod is provided between the support block and the mounting block. A protective shell 2 is located between the two support blocks, extending the service life of the cleaning component. The cleaning component is installed inside the protective shell 2.

[0020] In this invention, the cleaning component includes a fixed plate housed within a protective shell 2. A drying component is located on one side of the top of the fixed plate, and a sprayer is located on the other side of the top of the fixed plate. A sweeping component is installed at the bottom of the fixed plate. The cleaning component facilitates comprehensive cleaning of the PCB board surface, from wetting and sweeping to drying, ensuring that dust and impurities on the PCB board surface are thoroughly removed and moisture is completely evaporated, achieving a high level of cleanliness and dryness, effectively improving the cleaning quality and performance of the PCB board. The sprayer includes a water tank 8 fixed to the fixed plate and a water mist generator 7 installed on one side of the water tank 8. A water supply pipe is provided between the water mist generator 7 and the water tank 8. An atomizing nozzle is connected to the bottom of the water mist generator 7. The water mist generator 7 enhances the cleaning effect of the PCB board surface, allowing the sweeping component to more thoroughly remove contaminants. The drying component includes components installed on the fixed plate... The heater housing 9 is located on one side of the top of the board. Multiple heating rods 11 are arranged inside the heater housing 9. A fan 10 is installed on the top of the heating rods 11. An air outlet 12 is opened at the bottom of the drying component and extends through to the fixed plate. The drying component provides stable heat to ensure that the hot air has a sufficient temperature so that the moisture on the surface of the PCB board can evaporate quickly. The cleaning component includes four threaded rods that are threadedly connected to the fixed plate. The top of the four threaded rods is screwed with nuts for fixing. The bottom of the four threaded rods is fixed with a connecting plate. A sweeping disc 6 is rotatably mounted on the connecting plate. A small motor is coaxially connected to the top of the sweeping disc 6. The cleaning component can effectively remove dirt from the surface of the PCB board, ensuring that the PCB board surface is clean and improving the cleaning quality of the PCB board. A cleaning brush is detachably connected to the bottom of the sweeping disc 6 by Velcro. The cleaning brush is made of anti-static nylon material.

[0021] Working Principle: In the use of this utility model, firstly, each electrical component in this application is electrically connected to an external control device. Then, the drive motor 5 is started, outputting rotational power to drive the belt conveyor 3. The belt conveyor 3 begins to carry and transport the PCB board. Driven by the belt conveyor 3, the PCB board moves from one end of the device to the other, entering the cleaning process. At the same time, the servo motor on the mounting block drives the lead screw 4 to rotate according to the thickness of the PCB board to be cleaned. The lead screw 4 converts the rotational motion into the linear motion of the support block, driving the protective shell 2 and the internal cleaning components to move up and down, precisely adjusting the distance between the cleaning components and the PCB board surface to ensure the adaptability of the cleaning operation. When the PCB board is transported to the bottom of the cleaning components, the cleaning components begin to operate. Water in the water tank 8 flows into the water mist generator 7 through the water supply pipe. The water mist generator 7 converts the water into a uniform water mist, which is sprayed onto the PCB board surface through the atomizing nozzle. The water mist moistens the PCB board, reducing the adhesion of dust, impurities, and other pollutants to the PCB board, and also acts as a preventative measure against static electricity. The electric action reduces dust adsorption during the cleaning process. Subsequently, the small motor in the cleaning component starts, driving the sweeping disc 6 to rotate. The cleaning brush at the bottom of the sweeping disc 6 then sweeps and cleans the wetted PCB board surface, removing dust, impurities, and other contaminants. Because the cleaning brush is made of anti-static nylon and is detachably connected to the sweeping disc 6 via Velcro, it can effectively clean dirt and is easy to replace quickly after wear. After cleaning, the PCB board continues to move forward to the drying component. The heating rod 11 inside the heater housing 9 is energized and heats up. The fan 10 blows out the heat, accelerating airflow to form hot air. The hot air is evenly blown onto the PCB board surface through the air outlet 12, quickly evaporating the residual moisture on the PCB board surface and drying it to meet the requirements of subsequent processing. Finally, the protective shell 2 protects the cleaning components from external water mist and dust, ensuring the stable operation of each part. The PCB board completes the cleaning processes of spraying and wetting, cleaning dirt, and drying in sequence, achieving efficient and high-quality automated cleaning. The use of the PCB board surface cleaning device is now complete.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
