[0032] Figure 1 This is a structural schematic diagram of a seed crystal rod removal tool provided in this application. Figure 2 yes Figure 1 The top view of the seed crystal rod removal tooling, Figure 3 yes Figure 1 The front view of the seed crystal rod removal tooling is as follows: Figure 1 Grayscale fill is performed. Figure 1-Figure 3 The present embodiment provides a seed crystal rod removing tool, which comprises: a bottom plate 10, a fixed baffle plate 20, a movable baffle plate 30 and an adjustable fixing component 40, wherein the fixed baffle plate 10 and the movable baffle plate 20 are arranged on the same side of the bottom plate 10, and the fixed baffle plate 20 and the movable baffle plate 30 are respectively arranged at two ends of the bottom plate 10, the fixed baffle plate 20 is fixedly connected to the bottom plate 10, and the movable baffle plate 30 is slidably connected to the bottom plate 10 through the adjustable fixing component 40;

[0033] An accommodating space 50 is formed between the bottom plate 10 , the fixed baffle 20 and the movable baffle 30 , and the accommodating space 50 is used for placing silicon rods to be removed.

[0034] Specifically, the seed crystal rod extraction tooling includes a bottom plate 10, a fixed baffle 20, a movable baffle 30 and an adjustable fixing component 40, wherein the fixed baffle 10 and the movable baffle 20 are arranged on the same side of the bottom plate 10, and the fixed baffle 20 and the movable baffle 30 are respectively arranged at both ends of the bottom plate 10, so that a receiving space 50 is formed between the bottom plate 10, the fixed baffle 20 and the movable baffle 30, and the receiving space 50 can be used to place silicon rods to be extracted. The fixed baffle 20 is fixedly connected to the bottom plate 10, and the movable baffle 30 is slidably connected to the bottom plate 10 through the adjustable fixing component 40, that is, the movable baffle 30 can slide on the bottom plate 10. As the movable baffle 30 can slide on the bottom plate 10, the volume of the receiving space 50 formed between the bottom plate 10, the fixed baffle 20 and the movable baffle 30 will also change accordingly.

[0035] In the specific implementation process, the silicon rod to be removed can be placed in the accommodating space 50 formed by the bottom plate 10, the fixed baffle 20 and the movable baffle 30. The bottom plate 10 can support the silicon rod. The movable baffle 30 can slide on the bottom plate 10 by adjusting the fixing component 40 until the movable baffle 20 contacts the silicon rod, that is, the two ends of the silicon rod contact the fixed baffle 20 and the movable baffle 30 respectively. At this time, the fixed baffle 20 and the movable baffle 30 fix the two ends of the silicon rod, so that the silicon rod can be fixed in the seed crystal removal tooling, which is convenient for the subsequent removal of the silicon rod. The seed crystal removal tooling provided in this embodiment is used to fix the silicon rod, and the fixing method is stable. The quality of the seed crystal processed later is high, and it can be used to fix more silicon rods of different sizes, and the applicability is high. And when the seed crystal removal tooling provided in this embodiment is used to fix the silicon rod, there is no need to use adhesive to fix the silicon rod, which effectively reduces the cost.

[0036] At the same time, when the silicon rod needs to be replaced, the movable baffle 30 is made to slide on the base plate 10 by adjusting the fixing component 40, so that the volume of the accommodating space 50 formed between the base plate 10, the fixed baffle 20 and the movable baffle 30 is increased, thereby facilitating the replacement of the silicon rod, improving the efficiency of the silicon rod replacement, and reducing the production cost.

[0037] Continue to refer Figure 1-Figure 3 In some optional embodiments, the adjusting and fixing component 40 includes a threaded rod 41, a nut 42 and an angular contact ball bearing 43. The nut 42 is arranged opposite to the fixed baffle 20, and the nut 42 is fixedly connected to the base plate 10. The angular contact ball bearing 43 is embedded in the movable baffle 30, one end of the threaded rod 41 is embedded in the angular contact ball bearing 43, and the threaded rod 41 is threadedly connected to the nut 42.

[0038] Specifically, the adjusting and fixing component 40 includes a threaded rod 41, a nut 42 and an angular contact ball bearing 43. The nut 42 and the fixed baffle 20 are located on the same side of the bottom plate 10, and the nut 42 and the fixed baffle 20 are arranged opposite to each other, that is, the fixed baffle 20 is fixed at one end of the bottom plate 10, the nut 42 is fixed at the other end of the bottom plate 10, and the movable baffle 30 is located between the nut 42 and the fixed baffle 20. The angular contact ball bearing 43 is embedded in the movable baffle 30, one end of the threaded rod 41 is embedded in the angular contact ball bearing 43, and the threaded rod 41 is threadedly connected with the nut 42. Threaded transmission can be realized between the threaded rod 41 and the nut 42, so that the threaded rod 41 moves, and the threaded rod 41 drives the movable baffle 30 to move, so that the movable baffle 30 slides on the bottom plate 10. As the movable baffle 30 can slide on the bottom plate 10, the volume of the accommodating space 50 formed between the bottom plate 10, the fixed baffle 20 and the movable baffle 30 will also change accordingly.

[0039] In the specific implementation, the silicon rod to be removed can be placed in the accommodating space 50 formed by the base plate 10, the fixed baffle 20 and the movable baffle 30, and the threaded transmission between the threaded rod 41 and the nut 42 is adjusted to make the threaded rod 41 move toward the direction close to the fixed baffle 20, and the threaded rod 41 drives the movable baffle 30 to move toward the direction close to the fixed baffle 20, so that the movable baffle 30 slides on the base plate 10 until the movable baffle 20 contacts the silicon rod, that is, the two ends of the silicon rod contact the fixed baffle 20 and the movable baffle 30 respectively. At this time, the threaded transmission between the threaded rod 41 and the nut 42 is stopped, and the fixed baffle 20 and the movable baffle 30 fix the two ends of the silicon rod, so that the silicon rod can be fixed in the seed crystal removal tooling, which is convenient for the subsequent removal of the silicon rod.

[0040] At the same time, when the silicon rod needs to be replaced, the threaded transmission between the threaded rod 41 and the nut 42 is adjusted so that the threaded rod 41 moves in a direction away from the fixed baffle 20, and the threaded rod 41 drives the movable baffle 30 to move in a direction away from the fixed baffle 20, so that the volume of the accommodating space 50 formed between the bottom plate 10, the fixed baffle 20 and the movable baffle 30 is increased, thereby facilitating the replacement of the silicon rod, improving the efficiency of the silicon rod replacement, and reducing the production cost.

[0041] It should be noted that the embodiment of the present application exemplarily shows that the adjusting and fixing component 40 includes a threaded rod 41, a nut 42 and an angular contact ball bearing 43. The movement of the threaded rod 41 is achieved through the threaded transmission between the threaded rod 41 and the nut 42, so that the movable baffle 30 can slide on the base plate 10. In other embodiments of the present application, the adjusting and fixing component 40 can also adopt other structures, which only need to satisfy the sliding connection between the movable baffle 30 and the base plate 10. The present application will not elaborate on them one by one here.

[0042] Continue to refer Figure 1-Figure 3 In some optional embodiments, the threaded rod 41 is perpendicular to the plane where the movable baffle 30 is located.

Threaded transmission can be realized between the threaded rod 41 and the nut 42, so that the threaded rod 41 can move along a straight line, and the threaded rod 41 drives the movable baffle 30 to move, so that the movable baffle 30 can slide on the bottom plate 10. The threaded rod 41 is perpendicular to the plane where the movable baffle 30 is located, that is, the threaded rod 41 moves in a direction perpendicular to the plane where the movable baffle 30 is located, so that when the threaded rod 41 drives the movable baffle 30 to move, the stability of the movement of the movable baffle 30 is effectively improved.

[0046] Specifically, the threaded rod 41 is perpendicular to the plane where the movable baffle 30 is located, that is, the threaded rod 41 moves in a direction perpendicular to the plane where the movable baffle 30 is located. When the angular contact ball bearing 43 is embedded in the center of the movable baffle 30, the threaded rod 41 drives the movable baffle 30 to move at the center of the movable baffle 30, effectively improving the stability of the movement of the movable baffle 30.

[0047] In the adjusting and fixing component 40, a base boss 44 can be set between the base plate 10 and the nut 42. The base boss 44 is fixedly connected to the base plate 10, and the nut 42 is fixedly connected to the base boss 44. The base boss 44 can play a role of raising the nut 42, so that when the angular contact ball bearing 43 is embedded in the center of the movable baffle 30, the threaded rod 41 is perpendicular to the plane where the movable baffle 30 is located, so as to improve the smoothness of the movement of the movable baffle 30.

[0048] It should be noted that, along the direction perpendicular to the base plate 10, the height of the base boss 44 can be set according to the size of the nut 42, and it is only necessary to ensure that when the angular contact ball bearing 43 is embedded in the center of the movable baffle 30, the threaded rod 41 is perpendicular to the plane where the movable baffle 30 is located.

The setting of rotating the handwheel 45 can facilitate the movement of the threaded rod 41, thereby facilitating the movement of the movable baffle 30 and effectively simplifying the difficulty of operation.

[0051] Optionally, the handwheel 45 includes a handle 451 , and the handwheel 45 can be rotated by the handle 451 , thereby enabling threaded transmission between the threaded rod 41 and the nut 42 , thereby effectively further simplifying the difficulty of operation.

A limit block 31 is provided on the side of the movable baffle 30 close to the base plate 10, and the limit block 31 is at least partially located in the first groove 11. The first groove 11 is used to limit the movement of the movable baffle 30 along the extension direction of the first groove 11.

[0054] Specifically, a first groove 11 is provided in the base plate 10, and a limit block 31 is provided on the side of the movable baffle 30 close to the base plate 10. The limit block 31 is at least partially located in the first groove 11. When the movable baffle 30 moves on the base plate 10, the limit block 31 moves in the first groove 11. The first groove 11 is used to limit the movement of the movable baffle 30 along the extension direction of the first groove 11. The setting of the limit block 31 and the first groove 11 effectively reduces the risk of tilting of the movable baffle 30 when moving, and can improve the smoothness of the movement of the movable baffle 30.

[0055] It should be noted that the size of the first groove 11 can be set according to the size of the limit block 31 and the moving range of the movable baffle 30, and the present application does not make any specific limitation on this.
