The staff starts the second motor 8, so that the second motor 8 drives the screw 801 to rotate, and then drives the fixed plate 401 to slide along the protective cover 4, which is convenient to operate.

[0028] In at least one embodiment, the clamping mechanism includes a motor 3 9, an adjusting rod 901, a slider 902 and a splint 903. The motor 3 9 is fixedly arranged on one side of the storage plate 702. The storage plate 702 has mounting cavities 703 on both sides. The adjusting rod 901 passes through the mounting cavity 703 and is rotatably connected to the storage plate 702. A section of the adjusting rod 901 located in the mounting cavity 703 is set as a threaded section. A slider 902 is slidingly set in the mounting cavity 703. The slider 902 is sleeved on the adjusting rod 901. A splint 903 is fixed on the top of the slider 902. The staff starts the motor 3 9, so that the motor 3 9 drives the adjusting rod 901 to rotate.

[0031] In at least one embodiment, a plurality of fixed rods 501 are fixedly arranged at intervals on the top of the mounting frame 5, the fixed rods 501 are passed through the fixed plate 401, and a spring 502 is sleeved on a section of the fixed rod 501 below the fixed plate 401, and both ends of the spring 502 are respectively connected to the mounting frame 5 and the fixed plate 401. By arranging the fixed rods 501 and the spring 502 on the mounting frame 5, the grinding brush roller 601 can be vertically raised and lowered within a certain range under the action of the spring 502 when grinding the circuit board, so that effective grinding operations can be performed on circuit boards of different thicknesses, thereby improving the scope of application.

[0032] In at least one embodiment, an electric push rod 201 is fixedly provided on the top of the fixed frame 2, and the output shaft of the electric push rod 201 is connected and fixed to the lifting plate 3. When the staff starts the electric push rod 201, the output shaft of the electric push rod 201 can drive the lifting plate 3 to perform lifting operations, which is convenient to operate.

[0033] In at least one embodiment, a storage groove aligned with the protective cover 4 is provided on the base 1, a filter plate 101 is fixedly provided on the top of the storage groove, a fan is fixedly provided on the bottom of the storage groove 101, and filter holes are provided on the filter plate 101. When the brush roller 601 brushes the surface of the circuit board, the staff starts the fan, and the fan sucks the dust in the protective cover 4. The dust can enter the storage groove through the filter holes on the filter plate 101 for storage and collection, which is convenient to operate.

[0034] When performing the circuit board brushing operation, the staff places the circuit board on the storage plate 702 outside the turntable 7, and then rotates the turntable 7, so that the turntable 7 drives the storage plate 702 to rotate, thereby moving the circuit boards on one group of storage plates 702 to just below the protective cover 4, and then slides the lifting plate 3, so that the lifting plate 3 drives the protective cover 4 to descend in the vertical direction. When the bottom of the protective cover 4 abuts against the base 1, the grinding brush roller 601 in the protective cover 4 abuts against the surface of the circuit board on the storage plate 702, and then the staff starts the motor 6, so that the motor 6 drives the grinding brush roller 601 to rotate, thereby making the grinding brush roller 6 01 polishes the surface of the circuit board and removes the dust on the surface of the circuit board. The staff can use the driving mechanism to drive the fixed rod 501 to slide along the slide groove 402 in the protective cover 4, and then drive the brush roller 601 to move, so as to adjust the brush position of the circuit board to ensure that the circuit board is fully polished. The clamping mechanism on the storage plate 702 can clamp the circuit board to prevent the circuit board from sliding during brushing and ensure the polishing effect. During polishing, the card slot at the bottom of the protective cover 4 is embedded in the connecting rod 701 to ensure that the protective cover 4 completely covers the circuit board, preventing the dust generated during polishing from escaping outward, thereby improving the dust removal effect.
