[0037] Working principle and technical effect: the laser cutting device is fixed on the workbench of the laser cutting machine through the connecting plate 1, and is controlled by the laser cutting machine program (the automatic control program of the existing CNC laser cutting machine, the prior art will not be repeated), the motor 24 is energized and drives the active roller 3 and the driven roller 4 to rotate through the belt transmission relationship, so that the feeding end of the diamond original plate 14 is inserted into the feeding space 5 between the active roller 3 and the driven roller 4, and the discharge end of the diamond original plate 14 is transported by the active roller 3 and the driven roller 4 to enter the top of the return plate 11. When the diamond original plate 14 reaches the first cutting area, under the control of the laser cutting machine, the motor 24 is powered off, and the transportation of the diamond original plate 14 stops. At the same time, the laser cutting head 15 descends and cuts off a diamond cutter head from the discharge end of the diamond original plate 14 according to the cutting program and path.

The second cutter head falls onto the reflux plate 11, and so on to obtain N cutter heads. The N cutter heads fall onto the reflux plate 11, and after being polished on the top surface of the grinding plate 29 and the outer cylindrical surface of the third auxiliary roller 9, they are discharged in sequence through the reflux port 10.
