[0048] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a seed crystal cutting and clamping device, comprising: a base 1, a fixed component 2, a movable limit component 3 and a locking component 4. The fixed component 2 is installed on the top of the base 1, and one side of the fixed component 2 has a first fixed opening 21. The movable limit component 3 is slidably arranged on the top of the base 1, and a second fixed opening 31 is arranged on the side of the movable limit component 3 facing the fixed component 2. One end of the locking component 4 is connected to the fixed component 2, and the other end passes through the movable limit, and the spacing between the movable limit component 3 and the fixed component 2 can be adjusted according to the outer diameter size of the seed crystal mother rod.

[0050] When in use, the seed crystal mother rod is placed in the first fixing opening 21 of the fixing assembly 2, and then the position of the movable limiting assembly 3 is adjusted by the locking assembly 4, so that the movable limiting assembly 3 moves toward the fixing assembly 2. The seed crystal mother rod is fixed between the fixing assembly 2 and the movable limiting assembly 3.

[0051] The use of this clamping device can effectively prevent the AB glue from having insufficient bonding strength to support the force and vibration during high-speed cutting, and avoid edge collapse or hidden cracks in the crystal rod during processing.

[0052] In one embodiment, if Figure 3 and Figure 4 As shown, the base 1 is provided with a pad 5 in the area corresponding to the seed crystal mother rod installation. The pad 5 is made of polyurethane, and when the seed crystal mother rod is fixed, it is prevented from directly contacting the base 1 and causing damage due to collision.

[0053] In one embodiment, if Figure 1 As shown, in order to facilitate the installation of the base 1 on the processing equipment, connection openings 11 connected to the processing equipment are provided on opposite sides of the base 1.

[0054] In one embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 2 includes: a fixing plate 22 and two first positioning plates 23. The fixing plate 22 is welded to the top of the base 1. The two first positioning plates 23 are mounted on the side of the fixing plate 22 facing the movable limiting assembly 3 by screws. The first fixing opening 21 is arranged on the side of the first positioning plate 23 facing the movable limiting assembly 3, and the two first positioning plates 23 are arranged up and down.

[0055] The movable limit assembly 3 includes: a movable plate 32 and two second positioning plates 33. The movable plate 32 is connected to the two second positioning plates 33 by screws and is installed on the locking assembly after being connected. The second fixed opening 31 is arranged on the side of the second positioning plate 33 facing the first positioning plate 23. The two second positioning plates 33 are arranged up and down.

[0056] The first positioning plate 23 and the second positioning plate 33 are both made of polyurethane.

[0057] The welded overall structure of the base 1 can fully bear the weight of the seed crystal mother rod, and provide positive pressure downward with the help of its own weight, ensuring the stable fixation of the seed crystal mother rod, thereby indirectly solving the abnormal problem of edge collapse or hidden cracks at the bottom of the crystal rod due to the insufficient bonding strength of the AB glue to withstand the force and vibration in high-speed cutting.

[0058] The base 1, the fixed plate 22 and the movable plate 32 are all made of carbon steel, and the pad 5, the first positioning plate 23 and the second positioning plate 33 are all made of polyurethane, which solves the problem of edge collapse of the seed crystal head caused by the different hardness of the three media of silicon material, AB mixed glue and glass and the high-speed rotation of the cutter head during the digging process.

[0059] Driven by the locking component 4, the fixing component 2 and the moving positioning component adjust the distance between the first fixing opening 21 and the second fixing opening 31, so that the arc surface of the seed crystal fully contacts the inner wall of the first fixing opening 21 and the second fixing opening 31, thereby improving the stability of the seed crystal during processing.

[0060] In one embodiment, if Figure 2 and Figure 3 As shown, in order to improve the stability of the clamping device, the clamping device further includes: a reinforcing plate 6, which is installed on a side of the fixing component 2 away from the movable limiting component 3, and the bottom of the reinforcing plate 6 is connected to the base 1.

[0061] In one embodiment, if Figure 2 and Figure 3As shown, the locking assembly 4 includes: four screws and locking nuts. One end of the four locking screws 41 is installed on the fixed assembly 2, and the other end passes through the movable limit assembly 3; the locking nut is installed on the other end of the locking screw 41. Among them, the four locking screws 41 are distributed in a rectangular shape after installation, and the movable limit assembly 3 slides between the locking screws 41 and the locking nut, and the spacing between the fixed assembly 2 and the movable limit assembly 3 is adjusted by the locking nut.

[0062] In the process of clamping and fixing the seed crystal mother bar, the locking nut rotates, so that the movable limit assembly 3 moves toward the fixing assembly 2, and the seed crystal mother bar is fixed in the first fixing opening 21 and the second fixing opening 31. The inner walls of the first fixing opening 21 and the second fixing opening 31 are both arranged in an arc surface, which can increase the contact surface between the seed crystal mother bar and the first fixing opening 21 and the second fixing opening 31, so that the force on the seed crystal mother bar is more uniform during the clamping process, and the problem of internal cracks and edge collapse of the seed crystal mother bar caused by excessive local pressure is avoided, thereby ensuring the stability of the workpiece during the processing.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
