[0024] Working principle: When using the fixing tool for the filter wafer cutting die, the staff first fix the bottom plate 1 on the cutting table through four groups of bolts 25 and nuts 26. Then, place the wafer cutting die on the disc 15. Next, turn on the cylinder 19. The cylinder 19 drives the first slider 17 to slide on the second chute 16 by being rotatably connected to one end of the disc 15. At the same time, the first slider 17 drives the first connecting rod 20 to move. The first connecting rod 20 drives the second connecting rod 21 to rotate on the disc 15. The second connecting rod 21 drives the third connecting rod 22 to move.

The fixed plate 13 drives the disc 15 to move through the support column 14. The disc 15 drives the wafer cutting die to move. When it moves vertically to the required position, turn off the second motor 6. During the process, the cutting position of the wafer cutting die on the disc 15 can be adjusted by turning on the first motor 2 and the second motor 6 in sequence, so as to more accurately align the wafer die with the predetermined position of the cutting equipment, reducing the cutting error caused by position deviation and ensuring the cutting accuracy.
