With the cooperation of the nut block, the lifting function of the shell 13 can be realized, and then the lifting function of the polishing assembly can be realized, which is convenient for adjusting the position of the polishing assembly after the PCB board is turned over, so as to polish the back of the PCB board.

[0028] It should be noted that the cylinder 26 can control the distance between the polishing wheel and the PCB board, thereby facilitating the contact and separation of the polishing wheel and the PCB board, and can achieve the polishing function of the PCB board in cooperation with the polishing motor 9.

[0029] An edge ring 5 is fixedly connected to the top of the bottom plate 1, a center disk 3 is arranged on the inner side of the edge ring 5, a flip ring 4 is rotatably connected between the center disk 3 and the edge ring 5, a clamping assembly is arranged on the surface of the flip ring 4, the clamping assembly comprises a fixed slide rail 20 fixedly connected to the surface of the flip ring 4, a fixed clamping plate 21 fixedly connected to one end of the fixed slide rail 20, a movable clamping plate 24 slidably connected to the inside of the fixed slide rail 20 and an auxiliary plate 22 fixedly connected to the other end of the fixed slide rail 20, a threaded through hole is provided inside the auxiliary plate 22, a fastening screw 23 is threadedly connected to the threaded through hole, and one end of the fastening screw 23 is rotatably connected to the movable clamping plate 24;

[0031] A first dust box 6 is installed on the surface of the edge ring 5, and a second dust box 7 is installed on the surface of the center disk 3. A plurality of dust holes are opened on the surfaces of the first dust box 6 and the second dust box 7, and a plurality of cleaning hairs are arranged on the surfaces of the first dust box 6 and the second dust box 7.

[0032] It should be noted that when the flip ring drives the PCB to rotate close to the cleaning hair, the debris on the surface of the PCB can be cleaned away to prevent the debris from adhering to the surface of the PCB.

[0033] Furthermore, a gear ring 15 is fixedly connected to the back of the flip ring 4, a flip motor 14 is installed on the top of the top plate 2, and one end of the output shaft of the flip motor 14 is fixedly connected to a driving gear meshing with the gear ring 15;

[0034] It should be noted that the flip motor 14 drives the driving gear to rotate, which in turn drives the gear ring 15 to rotate, and the gear ring 15 drives the flip ring to rotate, which in turn drives the PCB board to make a circular motion, thereby realizing the flipping function of the PCB board.

[0040] When the utility model is used, the PCB board to be polished is placed between the fixed clamping plate 21 and the movable clamping plate, and then the fastening screw 23 is rotated so that the movable clamping plate cooperates with the fixed clamping plate 21 to achieve the clamping and fixing function of the PCB board;

[0041] Then, the cylinder 26 is turned on, and the cylinder 26 drives the polishing motor 9 to move downward, thereby driving the polishing wheel to move downward, so that the polishing wheel contacts the PCB board, and then the polishing motor 9 is turned on, so that the polishing wheel realizes the polishing function of the PCB board;

[0042] After the polishing of the top of the PCB is completed, the polishing wheel is moved away from the PCB, and the driving motor is turned on. The driving motor drives the driving gear to rotate, and then drives the gear ring 15 to rotate.

At the same time, the dust pump 18 is turned on. The dust pump 18 can make the first dust box 6 and the second dust box 7 generate suction, and then absorb the cleaned debris. The dust pump 18 transports the absorbed debris to the collection box 19 for collection;

[0043] When the flip ring drives the PCB board to rotate to the bottom, the back of the PCB board faces upward. At this time, the flip motor 14 is turned off, and then the lifting motor 10 is turned on. The lifting motor 10 drives the synchronous wheel 11 to rotate, and then drives the lifting screw 27 to rotate. With the cooperation of the nut block, the polishing assembly moves down close to the PCB board, and then the polishing assembly is used to realize the polishing function of the back of the PCB board. When the polishing is completed, the flip motor 14 is turned on again. The flip motor 14 drives the driving gear to rotate, and then drives the gear ring 15 to rotate. The gear ring 15 drives the flip ring 4 to rotate. The flip ring 4 continues to drive the PCB board to make a circular motion. When the back of the PCB board contacts the cleaning hair on the surface of the second dust box 7, the cleaning and absorption function of the debris on the back of the PCB board can be realized, thereby avoiding the dispersion of the debris.
