The upper top head is opposite to the lower top head, and the side skin tightening device is located on one side of the lower top head and is arranged on the same side as the pressing device.

[0008] Furthermore, the upper clamping mechanism includes an upper top head and a side skin tightening device, and the lower clamping mechanism includes a lower top head. The upper top head and the lower top head are opposite each other, and the side skin tightening device is located on one side of the upper top head and is arranged on the same side as the pressing device.

[0022] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to Figures 1 to 5A clamping mechanism for a silicon rod cutting device includes an upper clamping mechanism 1, a lower clamping mechanism 2, and a clamping device 3. The upper clamping mechanism 1 is opposite to the lower clamping mechanism 2 and clamps both ends of the silicon rod. The clamping device 3 includes a clamping block 31, which is movable toward the end face of the silicon rod and opposite the cutting seam on the end face of the silicon rod. A soft layer is provided on the clamping block 31 near the end face of the silicon rod.

[0024] As can be seen from the above description, the beneficial effect of this utility model is that: by setting the clamping block 31, it can be pressed into the cutting seam of the silicon rod end face by the soft layer through pressure deformation, so that after it is completely cut, it can prevent the edge skin from hitting the core rod and avoid edge breakage.

[0025] Furthermore, the clamping device 3 is mounted on the upper clamping mechanism 1.

[0026] As can be seen from the above description, the clamping device 3 can be installed on the upper clamping mechanism 1 according to the actual working conditions.

[0027] Furthermore, the clamping device 3 is mounted on the lower clamping mechanism 2.

[0028] As can be seen from the above description, the clamping device 3 can be installed on the lower clamping mechanism 2 according to the actual working conditions.

[0029] Furthermore, the upper clamping mechanism 1 includes an upper top head 12, and the lower clamping mechanism 2 includes a lower top head 22 and a side skin tightening device 23. The upper top head 12 is opposite to the lower top head 22, and the side skin tightening device 23 is located on one side of the lower top head 22 and is arranged on the same side as the pressing device 3.

[0030] As can be seen from the above description, the clamping device 3 located in the upper clamping mechanism 1 can cooperate with the edge clamping device 23 of the lower clamping mechanism 2 to clamp and fix the cut edge.

[0031] Furthermore, the upper clamping mechanism 1 includes an upper top head 12 and a side skin tightening device 23, and the lower clamping mechanism 2 includes a lower top head 22. The upper top head 12 and the lower top head 22 are opposite each other, and the side skin tightening device 23 is located on one side of the upper top head 12 and is arranged on the same side as the pressing device 3.

[0032] As can be seen from the above description, the clamping device 3 located in the lower clamping mechanism 2 can cooperate with the edge clamping device 23 of the upper clamping mechanism 1 to clamp and fix the cut edge.

[0033] Furthermore, the clamping device 3 is movable along the length of the cut slit parallel to the end face of the silicon rod.

[0034] As can be seen from the above description, the movable setting of the clamping device 3 allows it to be adapted to the cutting of silicon rods of different sizes.

[0035] Furthermore, the clamping device 3 also includes a driving device, which is connected to the clamping block 31 and drives it to move toward the end face of the silicon rod.

[0036] As described above, the clamping block 31 is driven to move toward the end face of the silicon rod by the driving device.

[0037] Furthermore, the upper clamping mechanism 1 includes an upper clamping frame 11 and an upper top head 12, and the lower clamping mechanism 2 includes a lower clamping frame 21 and a lower top head 22. A spring is connected between the upper top head 12 and the upper clamping frame 11, and a spring is connected between the lower top head 22 and the lower clamping frame 21.

[0038] As can be seen from the above description, the spring connecting the upper top head 12 and the upper clamping frame 11, and the spring connecting the lower top head 22 and the lower clamping frame 21, achieve shock absorption and buffering during top pressure clamping.

[0039] Furthermore, the upper clamping mechanism 1 also includes a rotary mechanism 13, which is disposed on the upper clamping frame 11, and the upper top head 12 is connected to the rotary mechanism 13.

[0040] As can be seen from the above description, the rotation adjustment during clamping by the upper clamping mechanism 1 can be achieved by setting the rotary mechanism 13.

[0041] Furthermore, the rotary mechanism 13 includes a driving gear 131 and a driven gear 132, the driving gear 131 meshing with the driven gear 132, and the upper top head 12 being connected to the driven gear 132 in a transmission connection.

[0042] As can be seen from the above description, the rotation mechanism 13 is driven by the transmission connection of the driving gear 131 and the driven gear 132. Compared with the traditional hollow rotating mechanism with worm gear, the gear setting can reduce structural interference.

[0043] Example 1:

[0044] like Figures 1 to 5 As shown, a clamping mechanism for a silicon rod cutting device includes an upper clamping mechanism 1, a lower clamping mechanism 2, and a clamping device 3. The upper clamping mechanism 1 is opposite to the lower clamping mechanism 2 and clamps both ends of the silicon rod. The upper clamping mechanism 1 includes an upper mandrel 12, an upper clamping frame 11, and a rotating mechanism 13. The upper clamping frame 11 is equipped with the rotating mechanism 13. The upper mandrel 12 is located on the lower side of the upper clamping frame 11, and a spring connects it to the upper clamping frame 11. The lower clamping mechanism 2 includes a lower mandrel 22, a lower clamping frame 21, and an edge tensioner 23. The lower mandrel 22 and the edge tensioner 23 are both located on the upper side of the lower clamping frame 21, and a spring connects the lower mandrel 22 to the lower clamping frame 21.

[0045] The clamping device 3 includes a clamping block 31 and a driving device. The clamping block 31 is disposed on one side of the upper clamping frame 11. The driving device is connected to the clamping block 31 in a transmission manner, driving the clamping block 31 to move toward the end face of the silicon rod and to be opposite the cutting seam of the end face of the silicon rod. A soft layer is provided on the clamping block 31 near the end face of the silicon rod. In this embodiment, the soft layer is made of polyurethane with a Shore hardness of 40-70.

[0046] The clamping device 3 is movable along the length of the cut slit parallel to the end face of the silicon rod. Specifically, the clamping device 3 also includes an adjusting block 32, which is connected to the clamping block 31. The adjusting block 32 has an elongated slot along the moving direction, the length of which is consistent with the moving direction. A bolt is locked into the elongated slot to fix it to the upper clamping frame 11. When it is necessary to adjust to fit silicon rods of different sizes, the adjusting block 32 can be moved to a suitable position along the length of the elongated slot beforehand, and then the bolt is locked into the elongated slot to fix the adjusting block 32 and the upper clamping frame 11.

[0047] In this embodiment, at least two clamping blocks 31 are provided on each of the two sides of the upper clamping frame 11. Correspondingly, adjusting blocks 32 connected to the clamping blocks 31 are provided on the other two sides. In this case, there is a situation where the adjusting blocks 32 of the clamping blocks 31 on opposite sides are provided on the same side of the upper clamping frame 11. In this case, the two adjacent adjusting blocks 32 are staggered, and the locking heights of the two adjusting blocks 32 are staggered to avoid mutual interference.

[0048] The edge tightening device 23 is located on one side of the lower top head 22, and is arranged on the same side as the pressing device 3.

[0049] The rotary mechanism 13 includes a driving gear 131 and a driven gear 132. The driving gear 131 meshes with the driven gear 132, and the upper clamping frame 11 is connected to the driven gear 132 in a transmission connection.

[0051] The difference between this embodiment and Embodiment 1 is that:

[0052] The upper clamping mechanism 1 includes an upper top head 12, an upper clamping frame 11, a rotating mechanism 13, and a side clamping device 23. The upper clamping frame 11 is equipped with the rotating mechanism 13. The upper top head 12 and the side clamping device 23 are both located on the lower side of the upper clamping frame 11, and a spring connects them to the upper clamping frame 11. The lower clamping mechanism 2 includes a lower top head 22 and a lower clamping frame 21. The lower top head 22 is located on the upper side of the lower clamping frame 21, and a spring connects the lower top head 22 and the lower clamping frame 21.

[0053] The clamping device 3 includes a clamping block 31 and a driving device. The clamping block 31 is located on one side of the upper clamping frame 11. The driving device is connected to the clamping block 31 in a transmission manner, driving the clamping block 31 to move toward the end face of the silicon rod and to be opposite the cutting seam of the end face of the silicon rod. The clamping block 31 is provided with a soft layer near the end face of the silicon rod.

[0054] The edge tightening device 23 is located on one side of the lower top head 22, and is arranged on the same side as the pressing device 3.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 1 is that:

[0057] like Figure 2 As shown, the upper clamping mechanism 1 also includes an air blowing device 14 and a cleaning device 15, both of which are located on one side of the upper head 12. The cleaning device 15 is configured with a cooling water channel to cool the cutting line and flush away impurities. The air blowing device 14 is configured with a high-pressure air pump to remove cutting debris.

[0058] In summary, the clamping mechanism of the silicon rod cutting device provided by this utility model, through the setting of the clamping block, can be pressed into the cutting seam of the silicon rod end face by the soft layer under pressure deformation. In this way, after the rod is completely cut, it can prevent the edge skin from colliding with the core rod and avoid edge chipping.
