[0003] This technical solution only solves the problem that the brush easily scratches and damages the chip surface. The cutting of integrated circuit chips is an important link in the semiconductor manufacturing process.

At this time, the water outlet pipe 511 is closed by the water outlet valve plate 512. At this time, negative pressure is formed between the partition 505 and the piston 506, so that the water inlet valve plate 510 is sucked open. At this time, the water inlet pipe 509 is connected, so that the filtered water in the filter box 501 is sucked into the suction box 504. By sucking the filtered water into the suction box 504 and then discharging it, the filtering effect is improved.

[0050] Working principle: When the present invention is in use, the cutting motor 208 is started, and the cutting grinding wheel 210 is driven to rotate by the cutting motor 208, and the wafer for manufacturing integrated circuit chips is cut by the rotating cutting grinding wheel 210, and the translation motor 207 is started to drive the translation gear 206 to rotate. When the translation gear 206 rotates, the two motor frames 203 are driven to move toward the middle of the wafer at the same time by the two translation racks 205 to adjust the cutting position, and the cutting grinding wheel 210 is protected by the protective cover 209, and cooling water is sprayed through the water spray pipe 211 to rinse the wafer and cool the cutting grinding wheel 210;

[0051] When the cutting motor 208 is started, the wheel shaft 309 is driven to rotate through the first transmission belt 315. When the wheel shaft 309 rotates, the shaft plate 312 is inserted into the shaft groove 310, so that the shaft sleeve 311 rotates along with the wheel shaft 309, and the grinding wheel 313 is driven to rotate through the shaft sleeve 311 to grind the edge of the chip after the cutting wheel 210 has completed the cutting. When the wheel shaft 309 rotates, the worm 410 is driven to rotate through the third transmission belt 411, and the worm wheel 408 is driven to rotate through the worm 410, so that the transmission shaft 407 rotates along with the worm wheel 408. At this time, the reciprocating wheel 405 is driven to rotate through the second transmission belt 409, so that the reciprocating rod 406 rotates along with the reciprocating wheel 405, and the reciprocating rod 406 rotates at the same time. Inserted into the reciprocating groove 404, the movable frame 401 is driven to reciprocate in the frame groove 402, and then the sleeve 311 is driven to reciprocate on the axle 309 through the movable frame 401, and the grinding wheel 313 is driven to reciprocate while rotating through the sleeve 311, so as to further improve the grinding effect of the grinding wheel 313. When the sleeve 311 contacts the surface of the wafer, the axle 309 is driven to rotate through the rotating arm 314, so that the connecting frame 307 is raised and moved away from the cutting wheel 210, and the movable groove 302 is driven to move away from the cutting wheel 210 through the lifting rod 306, so that the bottom end of the sleeve 311 can be adaptively attached to the wafer surface, so that the cutting assembly can be suitable for wafers of different thicknesses;

[0052] The water sprayed from the water spray pipe 211 is collected into the filter box 501 through the inclined plate 502, and the collected water is filtered through the filter layer 503. When the translation block 204 moves in the direction close to the translation gear 206, the suction rod 507 is driven to move into the suction box 504 through the synchronous frame 508, and the piston 506 is driven to move in the direction of the partition 505 through the suction rod 507. At this time, the water inlet pipe 509 is blocked by the water inlet valve plate 510. At this time, the water in the filter box 501 cannot enter the suction box 504. At the same time, the water outlet valve plate 512 is pushed open by the air pressure in the suction box 504, so that the water outlet pipe 511 is connected. At this time, the piston 506 and the partition 505 are closed. The water is discharged, and when the translation block 204 drives the synchronous frame 508 to move away from the translation gear 206, the piston 506 moves away from the partition 505. At this time, the water outlet pipe 511 is closed by the water outlet valve plate 512. At this time, negative pressure is formed between the partition 505 and the piston 506, so that the water inlet valve plate 510 is sucked open. At this time, the water inlet pipe 509 is conducted, so that the filtered water in the filter box 501 is sucked into the suction box 504. By sucking the filtered water into the suction box 504 and then discharging it, the filtering effect is improved, and the water discharged from the water outlet pipe 511 can be sprayed again through the water spray pipe 211, so that the water used for cutting the integrated circuit chip can be recycled.
