[0044] The cutting device 2 includes a cutting seat 22. A cutting groove 111 is provided on the top of the base 11. The cutting groove 111 is used to determine the moving track of the cutting seat 22. The bottom end of the cutting seat 22 is slidably arranged inside the cutting groove 111.

A cutting rope 28 is provided on one side of the slurry barrel 29, which is used to cut the single crystal silicon rod. The cutting rope 28 runs through the slurry barrel 29. Both ends of the cutting frame 23 are rotatably connected to rollers, on which the cutting rope 28 is sleeved. A motor 24 is fixedly provided on one side of the top of the cutting frame 23, which is used to drive the roller to rotate, and one of the rollers is coaxially connected to the output shaft of the motor 24.

[0046] A plurality of sleeve rods 25 are fixedly connected to one side of the cutting frame 23. One end of the sleeve rod 25 is plugged with an insertion rod 26. The sleeve rod 25 is used to determine the position of the insertion rod 26. A roller is rotatably provided at one end of the insertion rod 26. The cutting rope 28 is sleeved on the roller. A tension spring 27 is fixedly connected to the other end of the insertion rod 26. The tension spring 27 is used to give a thrust to the insertion rod 26. One end of the tension spring 27 is fixedly connected to the sleeve rod 25.

[0047] When cutting the single crystal silicon rod, the hydraulic rod 21 drives the cutting seat 22 to slide back and forth inside the cutting groove 111, and the cutting seat 22 drives the cutting frame 23 to slide. The cutting frame 23 makes the cutting rope 28 slide back and forth through the roller, and under the action of the tension spring 27, the insertion rod 26 slides away from the sleeve rod 25, so that the cutting rope 28 is in a taut state. At the same time, the motor 24 drives the cutting rope 28 to rotate through the roller. When the cutting rope 28 passes through the slurry barrel 29, it carries the cutting slurry inside the slurry barrel 29 to complete the reciprocating cutting of the single crystal silicon rod.

[0048] The elastic structure includes an unsealing rod 36, which is used to drive the sealing plate 34 to slide. The unsealing rod 36 passes through the pressing block 32, one end of the unsealing rod 36 is fixedly connected to the sealing plate 34, one end of the pressing block 32 is fixedly connected to a sealing spring 37, the sealing spring 37 is used to give a thrust to the unsealing rod 36, one end of the sealing spring 37 is fixedly connected to the unsealing rod 36, and a leakage hole 35 is arranged on the side of the sealing plate 34, the leakage hole 35 is used to release the airtightness inside the sealing plate 34 when the sealing plate 34 slides in a direction away from the pressing block 32, one end of the rotating plate 31 is fixedly connected to a feeding spring 38, the feeding spring 38 is used to give a thrust to the rotating plate 31, and one end of the feeding spring 38 is fixedly connected to the rotating groove 112;

[0049] One end of the base 11 is fixedly connected with a blanking plate 14, which is used to cut the slices of the single crystal silicon rod. When the pressing block 32 rotates to the bottom position, the bottom end of the unsealing rod 36 fits with the blanking plate 14;

[0050] When slicing one end of the single crystal silicon rod, the feeding spring 38 drives one end of the pressing block 32 to fit with the single crystal silicon rod through the rotating plate 31. At this time, the sealing plate 34 and one end of the single crystal silicon rod fit and shrink into the inside of the feeding trough 33 to form a sealed cavity, pressing and fixing one end of the single crystal silicon rod, increasing the fixing effect of the single crystal silicon rod and avoiding shaking during cutting. At the same time, under the action of the elastic force of the sealing spring 37, the unsealing rod 36 drives the sealing plate 34 to continue to slide into the inside of the feeding trough 33, applying a suction force to one end of the single crystal silicon rod. When the slicing of the single crystal silicon rod is completed, the slice is adsorbed on one end of the pressing block 32 to avoid falling and bumping after the slicing is completed.

[0051] When one end of the single crystal silicon rod is cut, the rotating plate 31 drives the pressing block 32 to rotate. When the pressing block 32 rotates to the bottom position, one end of the unsealing rod 36 fits against the unloading plate 14, so that the unsealing rod 36 overcomes the elastic force of the sealing spring 37 and slides. The unsealing rod 36 drives the sealing plate 34 to slide upward. At this time, the sealing plate 34 pushes the slice of the single crystal silicon rod to leave one end of the pressing block 32. At this time, the air leakage hole 35 is separated from the inside of the unloading trough 33, and the airtightness between the sealing plate 34 and the slice is released. The slice slides into the inside of the unloading plate 14. Compared with the common single crystal silicon rod slicing device, the fixation of the single crystal silicon rod during slicing is more stable, and the force uniformity during slicing is increased. After slicing, the device for fixing the single crystal silicon rod is used for unloading to avoid damage caused by collision of the slice.

[0052] The synchronization device 4 includes two lifting blocks 42, which are respectively arranged at the two end positions of the cutting groove 111.

[0054] The loading device 5 includes a loading block 51. In order to push the loading block 51 to slide when the lifting frame 41 slides downward, the loading block 51 is set to be wedge-shaped. When the lifting frame 41 slides downward, the bottom of the lifting frame 41 fits with one side of the loading block 51. One end of the loading block 51 is fixedly connected to a loading rod 52.

When the feeding spring 54 pushes the feeding rod 52 to slide back, the inclined surfaces of the latch teeth and the tooth block fit together, and the friction force is small. Under the cooperation of the feeding rod 52 and the matching spring 56, the feeding tooth plate 55 slides to one side, and the feeding tooth plate 55 will not cause the feeding gear 57 to rotate. The top of the feeding gear 57 is fixedly connected with an active rod 58, and one end of the active rod 58 is plugged with a driven rod 59.

The driven rod 59 is hinged to the fixed rod 13, and one end of the driven rod 59 is fixedly connected with a telescopic spring, and one end of the telescopic spring is fixedly connected to the active rod 58;

[0056] When the lifting frame 41 moves downward, it pushes the loading block 51 to slide, and the loading block 51 drives the loading rod 52 and the baffle plate 53 to slide, overcoming the elastic force of the loading spring 54, and the loading rod 52 drives the loading tooth plate 55 to slide. At this time, the loading tooth plate 55 drives the loading gear 57 to rotate, and the loading gear 57 drives the fixed rod 13 to slide a certain distance inside the loading trough 12 through the active rod 58 and the driven rod 59. When the lifting frame 41 moves upward, the loading spring 54 pushes the baffle plate 53 to make the loading rod 52 slide in the opposite direction, and the loading rod 52 drives the loading tooth plate 55 to slide in the opposite direction.
