[0036] A groove 31 is provided on one side of the top of the cleaning box 24, and an output groove 38 is provided inside the cleaning box 24 away from the cleaning rod 1 27. A cleaning rod 2 32 is penetrated and slidably connected to the bottom of the inner cavity of the output groove 38, and a brush 2 37 is installed on one side of the upper part of the cleaning rod 2 32.

[0037] The above scheme is adopted: firstly, the circuit board is placed on the transmission rod 3, and the circuit board is located between the two guide plates 44. The transmission of the transmission rod 3 and the limiting of the transmission roller 4 allow the circuit board to smoothly enter the cleaning groove 25. Then, the cleaning rod 1 27 slides in the second slide groove 26 by opening the second slide groove 26, so that the output rod 29 moves forward. When the cleaning rod 1 27 slides, the upper surface of the circuit board is cleaned by the brush 1 28. When the output rod 29 moves, it will contact the guide rod 34 to make the guide rod 34 swing. At the same time, the sliding rod 30 slides in the guide groove 35. During the swinging process of the guide rod 34, the guide groove 35, the second cleaning rod 32 and the second brush 37 are driven to move to clean the lower surface of the circuit board, so as to prevent the raised particle impurities from scratching the surface of the circuit board during grinding.

The grinding dust will fall into the box body 1 through the discharge chute 41, and the dust attached to the outer wall of the transmission roller 4 can be scraped off by the contact between the scraper 42 and the transmission roller 4.

[0041] The working principle and use process of the present invention:

[0042] During operation, the circuit board is first placed on the transmission rod 3, and the circuit board is located between the two guide plates 44. The transmission of the transmission rod 3 and the limiting of the transmission roller 4 allow the circuit board to smoothly enter the cleaning groove 25. Then, the second slide groove 26 is opened to allow the cleaning rod 1 27 to slide in the second slide groove 26, so that the output rod 29 moves forward. When the cleaning rod 1 27 slides, the upper surface of the circuit board is cleaned by the brush 1 28. When the output rod 29 moves, it will contact the guide rod 34 to make the guide rod 34 swing. At the same time, the sliding rod 30 slides in the guide groove 35. During the swinging process of the guide rod 34, the guide groove 35, the second cleaning rod 32 and the second brush 37 are driven to move to clean the lower surface of the circuit board to prevent the raised particle impurities from scratching the surface of the circuit board during grinding.

[0043] After the impurities on the surface of the circuit board are cleaned, the circuit board will be transferred to between the grinding roller 1 6 and the grinding roller 2 11 through the transmission rod 3 and the transmission roller 4, and then the cylinder 14 will be turned on to move the connecting plate 13 downward. At the same time, the connecting plate 13 will drive the slider 1 9, the motor 2 10 and the grinding roller 2 11 to move downward, so that the grinding roller 2 11 fits with the upper surface of the circuit board, and the grinding roller 1 6 fits with the lower surface of the circuit board for grinding. In the process of the connecting plate 13 moving downward, the air outlet pipe 2 18 will be driven to slide in the air outlet pipe 1 16, so that the air outlet pipe 3 21 and the air jet pipe 22 will also move downward at the same time. The circuit board after grinding can be sprayed with air through the air jet pipe 22, which can prevent the dust generated during the grinding process from easily clogging the holes on the circuit board.
