[0029] like Figure 1-2 As shown, a cleaning device for printed circuit boards includes a base 1 and a cleaning component 2 disposed on one side of the base 1 for cleaning the circuit board; it also includes a drying component 3 disposed on the other side of the base 1 for drying the circuit board, and a transmission component 4 is provided on the upper end of the base 1.

[0030] like Figure 3-4As shown in -6-7, the transmission component 4 includes a power rod 5 and a power roller 6. The power rod 5 is arranged in multiple groups and passes through the base 1. The power roller 6 is fixed to the upper part of the power rod 5. A transmission wheel 7 is fixed to the protruding part of the power rod 5. One end of the transmission wheel 7 is connected to a rotary motor. The rotary motor is fixed to the outside of the base 1. A conveyor belt 8 is wound between the power rollers 6, and a belt 9 is wound between the transmission wheels 7.

[0031] The transmission wheel 7 has a reinforcing groove on its upper part, and the belt 9 has anti-slip ribs on its inner side that match the reinforcing groove. The upper end of the conveyor belt 8 has through holes that connect to the adsorption chamber and the drying chamber respectively. The rotary motor is controlled by a microprocessor, which drives the transmission wheel 7 to rotate. The transmission wheel 7 drives each other to rotate via the belt 9. The transmission wheel 7 drives the power rod 5 and the transmission rollers on the power rod 5 to rotate. The multiple sets of transmission rollers drive the conveyor belt 8 to rotate, so as to realize the smooth transport of the printed circuit board and ensure that the circuit board is not damaged during the transport process. In addition, it is linked with the microprocessor to realize that the transport speed can be adjusted to adapt to different cleaning requirements.

[0032] like Figure 2-5 As shown in Figure 7, the cleaning assembly 2 includes a support shell 10, a filter plate 11, a return water pipe 12, a slider 13, an adjusting rod 14, a pressing plate 15, and a drain pipe 16. The support shell 10 is fixed to one side of the upper end of the base 1, and a cleaning chamber is formed between the support shell 10 and the base 1. A closed adsorption chamber is opened inside the base 1, and the filter plate 11 is arranged inside the adsorption chamber. The return water pipe 12 is fixed to one side of the base 1, and the slider 13 is slidably arranged inside the return water pipe 12. The adjusting rod 14 is threaded to the upper end of the return water pipe 12, and the pressing plate 15 is fixed to the lower end of the adjusting rod 14. A spring 17 is provided between the pressing plate 15 and the slider 13. The drain pipe 16 is arranged through the cleaning chamber and is connected to the return water pipe 12. A nozzle is provided at the lower end of the drain pipe 16.

[0033] The spring 17 is located inside the return water pipe 12. One end of the spring 17 contacts the pressing plate 15, and the other end of the spring 17 contacts the slider 13. The upper end of the return water pipe 12 has a drain outlet, and the upper part of the slider 13 has a water inlet that matches the drain outlet. The adsorption chamber is filled with adsorption material, and the bottom of the adsorption chamber is set with a specific slope. By adjusting the adjusting rod 14, the adjusting rod 14 is displaced at the upper end of the return water pipe 12, which causes elastic deformation of the spring 17. This allows the water pumped into the lower end of the return water pipe 12 to generate sufficient water pressure. After the drain outlet and the water inlet are connected, the water enters the drain pipe 16 from the return water pipe 12, circulating and filtering impurities and contaminants in the cleaning solution to ensure the cleanliness of the cleaning solution and achieve stable and adjustable cleaning water pressure.

[0034] like Figure 2-4As shown, the drying assembly 3 includes a support plate 18, an annular shell 19, and a heating plate 20. A drying chamber is provided on the other side of the base 1. The support plate 18 is fixed to the inside of the drying chamber. An air vent is provided on the upper part of the support plate 18. The annular shell 19 is fixed to the inside of the air vent. A closed pressurization chamber 21 is formed inside the annular shell 19. An exhaust port 22 is provided at the upper end of the pressurization chamber 21. The pressurization chamber 21 is connected to a turbine air pump through a conduit. The turbine air pump is fixed to one side of the base 1. The heating plate 20 is fixed to the upper end of the base 1. A sensor module is fixed to the upper end of the base 1.

[0035] A microprocessor is fixed to one side of the base 1. The sensor module includes a thermal sensor and a humidity sensor. The sensor module is connected to the microprocessor via wires. The turbine air pump is connected to the microprocessor via wires. The rotary motor is connected to the microprocessor via wires. The microprocessor controls the turbine air pump to draw gas into the pressurization chamber 21. After the gas is pressurized, it is discharged from the narrowed vent. The airflow at the upper end of the support plate 18 increases, creating a pressure difference with the gas at the lower end of the support plate 18. The gas is drawn into the upper end of the support plate 18 and then heated by the heating plate 20 controlled by the microprocessor before being blown onto the circuit board. The drying temperature and time are controlled by the sensor module and the microprocessor in linkage to avoid damage to the circuit board and to enhance ventilation to quickly remove moisture from the circuit board.
