[0028] Working principle: Since the existing FPC circuit board cutting dust-proof device has a dust suction mechanism that is generally fixed on the workbench, during the circuit board cutting process, the dust suction mechanism cannot synchronously follow the dust removal operation, so that the dust and debris generated during the cutting process cannot be removed well, and during the dust removal process, the debris cannot be prevented from flowing back, thereby affecting the dust removal effect; therefore, in view of the above problems, an FPC circuit board cutting dust-proof device is proposed; when cutting the circuit board, the pneumatic cylinder 4 is operated to make the pneumatic rod 5 drive the cutting knife 10 to move vertically downward until the cutting knife 10 moves vertically downward to contact the surface of the circuit board, and then the first motor 11 is started to rotate the cutting knife 10, and at the same time the third motor 21 is started to make the threaded rod 22 drive the T-shaped slider 3 to move, and then the cutting knife 10 is rotated.

Because the cutting component and the dust removal mechanism are both arranged on the sliding sleeve 7, the dust removal operation can be performed synchronously during the cutting process of the circuit board, so that the dust and debris generated during the cutting process can be well removed and collected, which greatly improves the dust removal effect.

[0029] During the dust removal process, in order to prevent the collected debris from flowing back, the second motor 19 is operated to rotate the partition fan plate 20, so that the collected debris can quickly enter the dust collecting hood 16, while also preventing the debris from flowing back when the debris collected in the bag 15 is too full, thereby achieving a better dust removal effect.
