A sealing plate 36 is fixedly connected to the front of the filter plate 37. A positioning seat 35 is fixedly connected to the front of the sealing plate 36.

[0033] Furthermore, the shape of the inner wall of the positioning seat 35 matches the outer shape of the clamping block 34 , and the clamping block 34 is movably connected to the inner wall of the positioning seat 35 , so that the clamping block 34 can limit the sealing plate 36 .

[0034] Furthermore, a rectangular opening is opened on the top of the fixed box 31 , and the clamping block 34 passes through the rectangular opening, so that the clamping block 34 can move through the rectangular opening.

[0035] Furthermore, the threaded rod 32 is threadedly connected to the bottom of the fixed box 31, and the bottom end of the threaded rod 32 is fixedly connected with a torsion sleeve, so that the threaded rod 32 can be driven to rotate by the torsion sleeve.

[0036] Furthermore, an opening is provided on the front side of the water tank 1 , and the sealing plate 36 is movably connected to the inner wall of the opening, so that the sealing plate 36 can seal the interior of the water tank 1 .

[0037] Embodiment 2

[0038] See also Figures 1 to 5 On the basis of the first embodiment, the cleaning mechanism 4 further comprises a water pump 41, the water pump 41 is fixedly connected to the back of the water tank 1, a delivery pipe 42 is fixedly connected to the top of the water pump 41, an end of the delivery pipe 42 away from the water pump 41 is fixedly connected to a spray rack 43, a support column 47 is fixedly connected to the top of the water tank 1, a top of the support column 47 is fixedly connected to a limit frame 44, a bolt rod 45 is threadedly connected to the top of the limit frame 44, and a clamping plate 46 is rotatably connected to the bottom end of the bolt rod 45, thereby further improving the stability of the PCB cleaning process.

[0039] Furthermore, a water pump 41 is fixedly connected to the front side with a water pumping pipe, and the water pumping pipe runs through the back side of the water tank 1 to achieve the purpose of stable water pumping.

[0040] Furthermore, the delivery pipe 42 is fixedly connected to the back of the collection frame 2 , and the delivery pipe 42 is fixedly connected to the inner wall of the collection frame 2 , so as to provide stable support for the delivery pipe 42 and the spray rack 43 .

[0041] Furthermore, the clamping plate 46 is slidably connected to the inner side of the limiting frame 44, and a handle is fixedly connected to the top of the bolt rod 45, so that the clamping plate 46 can move stably.

[0042] In actual operation, when this device is used, the staff first places the PCB board to be cleaned on the inner side of the limit frame 44, and then shakes the handle to drive the bolt rod 45 to rotate, and the clamping plate 46 slides and limits on the inner side of the limit frame 44, so that the clamping plate 46 can clamp and limit the PCB board, ensuring the stability of the PCB board during the cleaning process, and preventing it from deviating or falling off, so that the cleaning work can be further carried out.

[0043] When the limit is completed, the water pump 41 can be started to work. The water pump 41 draws out the water source inside the water tank 1 through the suction pipe, pumps it into the interior of the spray rack 43 through the delivery pipe 42, and sprays it out. Therefore, the top and bottom of the PCB board can be sprayed and cleaned at the same time to achieve a good cleaning effect. At the same time, the water source after cleaning is discharged into the interior of the water tank 1 again for recycling, thereby reducing the waste of resources.

[0044] When the cleaned water source flows back to the inside of the water tank 1, the filter plate 37 can filter and purify the impurities contained in the water source to ensure the purity of the recovered water source. When the filter plate 37 needs to be cleaned, inspected and maintained, the torsion sleeve is first twisted to drive the threaded rod 1 32 to rotate. Since the threaded rod 1 32 and the fixed box 31 are threadedly connected, the threaded rod 1 32 will drive the block 34 to move downward through the movable plate 33, so that the block 34 can be separated from the inside of the positioning seat 35, and the limit on the positioning seat 35 is cancelled. Then, the sealing plate 36 is pulled out of the filter plate 37 from the inside of the slide groove 38 by the handle, so that the filter plate 37 can be disassembled, which is convenient for the staff to disassemble, inspect and maintain the filter plate 37, thereby achieving good operating efficiency and enhancing the convenience of operation and use of the device.
