Before the diamond needs to be processed, the diamond is mounted on the diamond fixing seat (27) by means of colloid, and then the light blocking plate (35) is flipped upward by holding the support foot (36) so that the light blocking plate (35) drives the fixing plate (33) to move to the top of the support plate (31). At this time, the second magnet (38) is adsorbed on the top of the first magnet (37), so that the light blocking plate (35) is placed upright. At the same time, during the closing process of the fixing plate (33) and the support plate (31), one end of the U-shaped tube (55) drives the conical sealing ring (57) to move to the inside of the through hole (54), thereby completing the connection of the channel; S2, the fan (52) draws air through the air inlet grille (58) and discharges the air through the connecting pipe (53), the gas enters the interior of one end of the U-shaped tube (55) through the through hole (54), and then the gas is discharged through the air outlet hole (56), and the discharged gas can assist in heat dissipation of the light baffle (35); S3, during processing, the laser cutting head (23) is driven to move by the first linear module (21) and the second linear module (22), and the laser processing of the diamond is completed by adjusting the position of the laser cutting head (23), and at the same time, the third linear module (25) drives the rotary cylinder (26) to rotate, so as to adjust the angle of the diamond on the diamond fixing seat (27); S4. When the light shielding plate (35) is replaced, the U-shaped frame (45) is pulled to move inside the slide groove (44), so that the U-shaped frame (45) drives the two connecting blocks (46) to move at the same time, and the elastic limiting column (42) contacts the inclined surface of the through groove (47), so that the elastic limiting column (42) is deformed by force, thereby pushing the elastic limiting column (42) to flip and move, so that the elastic limiting column (42) moves out of the arc groove, and then moves out of the slot (41) through the plane, and then the elastic limiting column (42) at the other end is moved out of the slot (41), and the light shielding plate (35) is pulled upward to be separated from the slot (34), and the light shielding plate (35) can be disassembled.
