In other examples, the side wall of the rotating clamping plate 343 has a rotation angle scale corresponding to the first cavity 3431, and the angle of the rotating clamping plate 343 can be adjusted visually by matching with the pointer on the fixed shaft 342, which is convenient and reliable.

In some examples, the blade end of the lobe blade 344 is V-shaped in cross-section. By the arrangement, the drag of the scraping plate can be reduced, the splitting effect of the optical filter can be improved, and the small optical filter piece with small area can be ensured to be split.

In some examples, sensing component 360 is a pressure sensor.

Because the optical filter is coated on the wafer ring by the UV film, the force of the optical filter, which is close to the outer film of the wafer ring, is larger under the same downward pressure, if the optical filter is cracked, the force acting on the optical filter under the same height can be changed greatly, the quality of the cracked piece can be influenced, the force during the cracked piece is monitored in real time by the pressure sensor, and the cracked piece state is controlled according to the measured value.

The specific working process of the device is as follows:

1. the wafer ring covered with the middle piece of the IR filter is placed in the storage bin 213, and then the storage bin 213 is placed on the connecting plate 212, and the first wafer ring of the storage bin 213 is aligned to the fixing frame 314 under the driving of the second moving module 211.

2. The first moving module 221 drives the ring clamping air claw 223 to approach the wafer ring, takes out the wafer ring from the storage bin 213, then moves to the supporting base 311 and the fixing frame 314, and the ring fixing cylinder 313 is started to drive the fixing frame 314 to fix the wafer ring.

3. The third moving module 321 drives the scraper assembly 340 to act on the middle piece of the IR filter of the wafer ring, then the fourth moving module 331 drives the scraper assembly 340 to split, the middle piece of the IR filter is split in the first direction, and after the completion, the rotary cylinder 323 rotates by 90 degrees, and the middle piece of the IR filter is split in the second direction.

4. After the wafer is cracked, the ring fixing air cylinder 313 is loosened, the first moving module 221 drives the ring clamping air claw 223, and the wafer ring is placed back into the storage bin 213, so that one layer of wafer ring cracking processing is completed, and the wafer ring cracking processing of the whole storage bin 213 is completed in the same way.
