[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: including a cutting table 1, a support frame 11 is fixed at the rear side of the upper end of the cutting table 1, a hydraulic cylinder 2 is fixed at the front side of the support frame 11, a pressure rod 21 is fixed at the output end of the hydraulic cylinder 2, a circular cutter head 4 is fixed at the bottom of the pressure rod 21, a rotating plate 3 is rotatably connected to the middle position of the upper end of the cutting table 1, storage grooves 31 are equidistantly arranged at the upper end of the rotating plate 3, through holes 32 are arranged at the bottom of the storage grooves 31, the positions of the storage grooves 31 are aligned with the circular cutter head 4, a feeding sleeve 5 is fixed at the upper end of the cutting table 1 and aligned with one of the storage grooves 31 through a connecting frame 51, a synchronous rotating shaft 72 is rotatably connected to the front side of the upper end of the cutting table 1, a discharging plate 7 is fixed at the upper end of the synchronous rotating shaft 72, electromagnets 71 are equidistantly fixed at the bottom of the discharging plate 7 and aligned with the storage grooves 31, and a collection box 6 is fixed at the front end of the cutting table 1 and aligned with the electromagnets 71.

[0018] A transmission gear 34 is fixed on the periphery of the rotating plate 3, a connecting gear 73 meshing with the transmission gear 34 is fixed on the synchronous rotating shaft 72, a stepping motor 33 for driving the rotating plate 3 to rotate is fixed inside the cutting table 1, and a discharging hole 12 is arranged on the cutting table 1, and the position of the discharging hole 12 is aligned with the circular cutter head 4.

[0019] A stabilizing sleeve 22 is slidably connected to the pressure rod 21, a connecting spring 23 is fixed between the inner side wall of the stabilizing sleeve 22 and the upper end of the circular cutter head 4, a top-out block 41 is installed inside the circular cutter head 4, a reset spring 43 is fixed between the upper end of the top-out block 41 and the inner wall of the circular cutter head 4, a guiding rod 42 is fixed on the inner side wall of the circular cutter head 4, a guiding groove 44 is arranged at the upper end of the top-out block 41 and corresponding to the guiding rod 42, the diameter of the circular cutter head 4 is adapted to the size of the through hole 32, and the diameter of the storage groove 31 is matched with the size of the stabilizing sleeve 22.

[0020] Working principle: First, connect the entire device to an external power supply, and then stack the wafers into the feeding sleeve 5. As the rotating plate 3 rotates, the lowermost wafer can sequentially enter the corresponding storage slots 31 and then enter below the annular cutter head 4 one by one. At this time, driven by the output end of the hydraulic cylinder 2, the pressure rod 21 and the annular cutter head 4 are driven to press down, enabling the hole-cutting operation of the wafer. After the hole-cutting is completed, continue to rotate so that the position of the storage slot 31 is aligned with the blanking plate 7. By energizing and adsorbing with the electromagnet 71, the wafer is sucked out from the storage slot 31. Then, by rotating the blanking plate 7, the adsorbed wafer is aligned with the collection box 6. By cutting off the power, the cut wafer can be dropped into the collection box 6 to complete the entire cutting process. The operation is simple and conducive to improving work efficiency. During the whole process, the rotating plate 3 can rotate following the output end of the stepping motor 33, and through the transmission of the transmission gear 34 and the connecting gear 73, the synchronous rotating shaft 72 can be driven to rotate synchronously. During cutting, when the pressure rod 21 moves downward, the stabilizing sleeve 22 will first abut against the wafer, pressing down the periphery of the wafer to maintain its stability. After continuous pressing down, the annular cutter head 4 will penetrate through the wafer. At this time, the ejecting block 41 will move into the annular cutter head 4, compressing the return spring 43. After complete cutting, the return of the return spring 43 will eject the waste material cut and discharged from the annular cutter head 4 through the discharge hole 12, which can prevent the waste material from remaining in the annular cutter head 4 and affecting subsequent cutting.
