DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with embodiments.

[0021] Example 1: The present invention provides a circuit board waterproof detection device, such as Figures 1 to 5 As shown, it includes a cabinet body 1, a cabinet door 2 is hinged at one end of the cabinet body 1, a control panel 3 is fixedly installed at one end of the cabinet body 1 at the side position of the cabinet door 2, and a connecting line is provided inside the cabinet body 1. The above are all existing technologies and are not repeated here. The control panel 3 is electrically connected to the motor 4, the first water pump 8 and the second water pump 9. The motor 4 is fixedly installed inside the cabinet body 1, and a drainage cover plate 5 is movably connected to the front position of the motor 4 inside the cabinet body 1. A waste water tank 6 is provided at the bottom end of the drainage cover plate 5, and the bottom end of the waste water tank 6 is fixedly connected to the inside of the cabinet body 1. A filter cartridge 7 is fixedly connected to the inside of the waste water tank 6, and the filter cartridge 7 is fixedly connected to the first water pump 8. The water inlet of the first water pump 8 is connected to the filter cartridge 7, and the water outlet of the first water pump 8 is fixedly connected to a water storage tank 19. The inside of the water storage tank 19 is fixedly connected to a water inlet pipe 10 at a position relative to the water outlet of the first water pump 8. The water inlet pipe 10 is fixedly connected to the inside of the cabinet 1. Both ends of the water storage tank 19 are fixedly connected to the second water pump 9. The water inlet of the second water pump 9 is connected to the water storage tank 19, and the water outlet of the second water pump 9 is fixedly connected to a drain pipe 11. The drain pipe 11 is fixedly connected to the inside of the cabinet 1, and one end of the drain pipe 11 is fixedly connected to a positioning frame 12. The interior of the positioning frame 12 is hollow, and a plurality of nozzles 13 are fixedly installed on the outer surface of the positioning frame 12.

[0022] like Figure 1 and Figure 5 As shown, the end of the output shaft of the motor 4 is fixedly connected to a disc 14, and both sides of the top of the disc 14 are fixedly connected to fixed blocks 15. A spring telescopic rod 16 is fixedly installed inside the fixed block 15, and a rubber block 17 is fixedly connected to the movable end of the spring telescopic rod 16. A limit plate 18 is movably connected to the bottom of the rubber block 17 inside the fixed block 15. When it is necessary to perform a waterproof test on the circuit board, the circuit board is taken out and placed in the position below the fixed block 15, and the limit plate 18 is pulled outward so that the limit plate 18 no longer contacts the rubber block 17. Then, due to the elastic force of the spring telescopic rod 16, the spring telescopic rod 16 drives the rubber block 17 to move downward, thereby squeezing and fixing the circuit board, effectively improving the stability of the circuit board.

[0023] like Figure 1 and Figure 4 As shown, the bottom end surface of the drainage cover plate 5 is fitted with the top end surface of the wastewater tank 6, and a plurality of drainage holes are provided inside the drainage cover plate 5, so that wastewater can flow into the wastewater tank 6 along the drainage holes, thereby realizing effective collection of wastewater, facilitating the secondary utilization of wastewater, and improving the efficiency and utilization rate of wastewater treatment.

[0024] like Figure 1 and Figure 4As shown, the filter cartridge 7 is internally provided with a plurality of filter holes away from one end of the first water pump 8, which can effectively intercept and filter impurities in the water, avoid these impurities entering the first water pump 8, thereby ensuring the stability and service life of the first water pump 8, and improving the reliability of the first water pump 8.

[0025] As shown in Figure 1 and Figure 5 As shown, the rubber block 17 is in the shape of a cylinder, and the bottom end face of the rubber block 17 is in close contact with the top end face of the limiting plate 18, preventing the rubber block 17 from moving under the action of the spring telescopic rod 16. The limiting plate 18 can limit the rubber block 17.

[0026] As shown in Figure 1 and Figure 5 As shown, the limiting plate 18 is in the shape of T, and the size of the limiting plate 18 near the rubber block 17 is smaller than the size of the other end, which can realize accurate positioning and ensure high precision and stability in the assembly process.

[0027] Working principle: during actual use, first, the circuit board to be waterproof detected is taken out and placed on the top end face of the disc 14. The position of the circuit board is adjusted so that it is located below the fixed block 15. Then the limiting plate 18 is pulled out to the outside so that the limiting plate 18 is no longer in contact with the rubber block 17. Then, under the action of the spring force of the spring telescopic rod 16, the spring telescopic rod 16 drives the rubber block 17 to move downward, which can realize the extrusion and fixation of the circuit board, effectively improve the stability of the circuit board, and ensure that the circuit board will not move or displace during subsequent detection, thereby ensuring the accuracy and reliability of the detection.

[0028] Then the external water pipe is connected with the water inlet pipe 10, the water tank 19 is filled with water, and then the motor 4 and the second water pump 9 are started by controlling the control panel 3. The output end of the motor 4 can drive the disc 14 to rotate, the disc 14 can drive the fixed block 15 to rotate synchronously, the fixed block 15 can drive the spring telescopic rod 16 and the rubber block 17 to rotate synchronously, and the rubber block 17 can drive the circuit board to rotate synchronously. The second water pump 9 starts to pump the water in the water tank 19 into the drain pipe 11, and then into the positioning frame 12 along the drain pipe 11, and then sprayed out along the spray head 13. The water flow sprays on the surface of the circuit board. As the circuit board rotates, the water flow can fully spray the circuit board. Then the used wastewater falls into the cabinet 1, and then the first water pump 8 is started. The first water pump 8 pumps the water in the wastewater tank 6, and the wastewater passes through the filter cartridge 7, and then enters the water tank 19 through the water outlet of the first water pump 8, thereby realizing the effective collection of the wastewater, facilitating the secondary utilization of the wastewater, and improving the efficiency and utilization rate of the wastewater treatment.

[0029] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them.
