Diamond tool cutting method is one of the methods for preparing silicon core. The silicon rod is fixed on a machine tool and cut with diamond wire by high-speed reciprocating or unidirectional movement of thin steel wire electroplated with diamond particles on the workpiece. The silicon rod is cut into long and thin silicon cores. The advantages are very obvious. About 200 7X7 or 8X8 mm square silicon cores with a length of 2 meters can be cut in 10-12 hours. The power consumption is small and the processing efficiency is high.

[0003] At present, the masterbatch for silicon core cutting directly adopts silicon rods produced in a reduction furnace. When cutting the silicon core, the silicon rods need to be clamped on a cutting machine. The silicon rods are hard and brittle, and are easily broken by severe vibration and impact, thus affecting the final product quality and yield rate.

[0023] The adjustment assembly 11 includes a bottom plate 13 arranged on the outside of the sleeve 1, two support plates 14 are symmetrically fixed on the bottom plate 13, the sleeve 1 is rotatably connected to the two support plates 14, and a gear ring 16 is fixed to one end of the two sleeves 1 away from the support plate 14. A gear 17 is meshed on one side of the gear ring 16, and a rotating rod 18 is fastened and sleeved at the center of the gear 17. The rotating rod 18 is rotatably connected to the support plate 14, one end of the rotating rod 18 passes through the support plate 14, and a fixed plate b19 is fixed to the outer wall of the support plate 14. A push block 20 is arranged on the outside of the rotating rod 18, and the push block 20 is away from the support plate A connecting sleeve b21 is fixed to one side of the rotating rod 18, and a screw b22 is rotatably connected inside the connecting sleeve b21. The screw b22 is threadedly connected to the fixed plate b19. The rotating rod 18 drives the gear 17 to rotate, and the gear 17 drives the gear ring 16 to rotate, so that the two sleeves 1 can rotate synchronously. The two ends of the silicon rod are respectively clamped in the two sleeves 1. The rotating rod 18 can drive the silicon rod to rotate. The push block 20 is pushed by rotating the screw b22 to limit the rotation of the rotating rod 18, thereby achieving the purpose of adjusting the position of the rotating silicon rod and facilitating the cutting of the diamond wire.

[0024] The anti-slip component 12 includes a groove 23 opened on the side of the clamping plate 4 away from the straight rod 3, and an anti-slip block 24 is slidably connected in the groove 23. A plurality of hollow grooves 25 are opened on the anti-slip block 24. A circular hole 26 is opened on the top surface of the anti-slip block 24. A countersunk screw 27 is arranged in the circular hole 26. The countersunk screw 27 is threadedly connected to the clamping plate 4.

The push plate 6 with an arc shape on the inner side provides thrust for the connecting block 5 to push the straight rod 3, so that the clamping plate 4 clamps the outer surface of the silicon rod more closely. The multiple surrounding clamping plates 4 can firmly clamp silicon rods of different diameters. The anti-slip block 24 is fixedly connected to the clamping plate 4 through the cooperation of the countersunk screw 27 and the groove 23. If the anti-slip block 24 is damaged by aging and the anti-slip function is weakened, it can be quickly replaced. The rubber anti-slip block 24 and the hollow groove 25 cooperate to softly clamp the silicon rod to prevent the silicon rod from slipping. The two sleeves 1 can rotate synchronously, and the two ends of the silicon rod are clamped in the two sleeves 1 respectively. The silicon rod can be driven to rotate by rotating the rotating rod 18. The push block 20 is pushed by rotating the screw b22 to limit the rotation of the rotating rod 18, so as to achieve the purpose of adjusting the position of the rotating silicon rod and facilitate the cutting of the diamond wire: when the cutting process is completed, the screw a9 is rotated in the reverse direction, and the push plate 6 is driven to move in the reverse direction through the connecting sleeve 8. The straight rod 3 drives the clamping plate 4 to separate from the surface of the silicon rod, and the silicon rod can be removed.
