[0002] During the single crystal pulling process of a single crystal furnace, the thermal field is the core component for single crystal growth. The correct use of the thermal field can effectively improve the crystal formation situation of the single crystal furnace. Since crystallization, local bulging, bending and other deformation problems will occur to the quartz crucible during use, in order to prevent liquid leakage after long-term single crystal pulling, usually after pulling a furnace of single crystals, it is necessary to remove and replace the quartz crucible in the carbon-carbon crucible.

Usually, workers use a hammer to directly break the quartz crucible. During the knocking process, the consistency of the striking force is low, which is likely to damage the carbon-carbon crucible. Moreover, manual operation has a high labor intensity, low work efficiency and potential safety hazards. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "set" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0045] As Figure 1 shown, an apparatus for breaking a quartz crucible according to an embodiment of the present utility model includes a base 50, on which a vibration platform 10, a clamping assembly 20, and a knocking assembly 30 are provided. The base 50 is welded by steel pipes and steel plates and can be integrally provided or detachably provided and fixedly connected. Heavy-duty foot cups are installed at the bottom of the base 50. The vibration platform 10 is used to place a carbon-carbon crucible with a quartz crucible, and the central axis of the carbon-carbon crucible is parallel to the vibration platform 10, so that the outer sidewall of the carbon-carbon crucible is placed on the vibration platform 10. The clamping assemblies 20 are oppositely arranged on both sides of the vibration platform 10 and are used to clamp the outer side of the carbon-carbon crucible. The knocking assembly 30 is arranged on the side of the vibration platform 10 where the clamping assembly 20 is not provided. When the carbon-carbon crucible is placed, the top opening of the carbon-carbon crucible faces the knocking assembly 30. The knocking assembly 30 can move along the inner sidewall of the quartz crucible and knock the inner sidewall of the quartz crucible to break the quartz crucible.

[0046] Specifically, as Figure 2 and Figure 3As shown, the clamping assembly 20 includes a clamping bracket 21, a clamping base 22, and a driving cylinder 23. On one side of the top of the clamping bracket 21 close to the carbon-carbon crucible, there is a clamping plate 24. The clamping base 22 is arranged at the bottom of the clamping bracket 21 and is rotatably connected to the clamping bracket 21. The driving cylinder 23 is arranged on the side of the clamping bracket 21 away from the carbon-carbon crucible and can drive the clamping bracket 21 to rotate close to or away from the vibration platform 10, making it more convenient to pick up and place the carbon-carbon crucible. The fixed end of the driving cylinder 23 is hinged to the clamping base 22, and the movable end of the driving cylinder 23 is hinged to the upper part of the clamping bracket 21. When the driving cylinder 23 contracts, it can drive the clamping bracket 21 to rotate away from the vibration platform 10, so that the clamping bracket 21 drives the clamping plate 24 to move away from the vibration platform 10. When the driving cylinder 23 extends, it can drive the clamping bracket 21 to rotate towards the vibration platform 10, so that the clamping bracket 21 drives the clamping plate 24 to move towards the vibration platform 10. The clamping bracket 21 is made by welding profiles. The shape of the clamping plate 24 is not limited. In this embodiment, the clamping plate 24 is a rectangular plate. On the upper part of the clamping plate 24, a first abutting plate 241 is obliquely fixed to abut against the side wall of the carbon-carbon crucible. On one end of the clamping plate 24, a second abutting plate 242 is obliquely fixed to abut against the bottom of the carbon-carbon crucible, which is more conducive to clamping and fixing the carbon-carbon crucible.

[0047] Specifically, a rotating shaft 221 is provided on the clamping base 22, and the bottom of the clamping bracket 21 is connected to the rotating shaft 221. In this embodiment, the clamping base 22 includes a bottom plate 222, the bottom plate 222 is fixedly connected to the base 50, a support column 223 is fixed on the upper part of the bottom plate 222, and a mounting plate 224 is fixed on the upper part of the support column 223. Both ends of the rotating shaft 221 are rotatably connected to the mounting plate 224 by bearings 225. The bottom of the clamping bracket 21 is fixedly connected to the rotating shaft 221 by a connecting seat 228. The fixed end of the driving cylinder 23 is hinged to the bottom plate 222, and drives the rotating shaft 221 at the bottom of the support frame to rotate through telescopic movement. A limiting block 226 is fixed on the side of the rotating shaft 221 away from the driving cylinder 23, and the limiting block 226 is fixed on the mounting plate 224. When the driving cylinder 23 extends and the clamping bracket 21 rotates towards the vibration platform 10 and the bottom of the support bracket abuts against the limiting block 226, the driving cylinder 23 stops extending, and at this time the support bracket is in a vertical state.

[0048] Preferably, locking cylinders 227 are provided on both sides of the clamping bracket 21, and the locking cylinders 227 are arranged on the clamping base 22. In order to prevent the clamping bracket 21 from moving and being unable to clamp the carbon-carbon crucible, which affects the breaking of the quartz crucible, when the clamping bracket 21 rotates to the vertical state, the locking cylinders 227 on both sides extend to abut against both sides of the clamping bracket 21 to lock the clamping bracket 21. In this embodiment, the locking cylinders 227 are fixed on the mounting plate 224 on the side close to the driving cylinder 23.

[0049] Specifically, a first driving assembly 25 is provided at the top of the clamping bracket 21. The first driving assembly 25 is connected to the side of the clamping plate 24 away from the carbon-carbon crucible and can drive the clamping plate 24 to approach or move away from the carbon-carbon crucible. The specific form of the first driving assembly 25 is not limited. In this embodiment, the first driving assembly 25 is specifically a turbine-screw structure. The turbine-screw structure is fixed on the clamping bracket 21. The screw is arranged perpendicular to the clamping plate 24, and the end is fixedly connected to the side of the clamping plate 24 away from the carbon-carbon crucible. An electric motor is used to drive the turbine to rotate, causing the screw to move horizontally, thereby driving the clamping plate 24 to approach or move away from the carbon-carbon crucible. The turbine-screw structure is a prior art and will not be elaborated here.

[0050] Preferably, a guiding shaft 26 is provided on the side of the clamping plate 24 away from the carbon-carbon crucible. The guiding shaft 26 is movably connected to the clamping bracket 21. The number of guiding shafts 26 is not limited. In this embodiment, guiding shafts 26 are fixed at both ends of the clamping plate 24. The guiding shafts 26 are arranged perpendicular to the clamping plate 24. Sleeves 27 are fixed at the positions corresponding to the guiding shafts 26 on the top of the clamping bracket 21. The guiding shafts 26 are in clearance fit with the sleeves 27. The first driving assembly 25 can drive the guiding shafts 26 to move along the sleeves 27 through the clamping plate 24.

[0051] Specifically, as Figure 4 shown, the knocking assembly 30 includes a cantilever 31, pneumatic hammers 32 arranged in opposite directions, and a second driving assembly 33. The cantilever 31 is horizontally arranged along the inner side wall of the quartz crucible. The pneumatic hammers 32 arranged in opposite directions are arranged at one end of the cantilever 31 close to the vibration platform 10. The two pneumatic hammers 32 arranged in opposite directions are fixed at the end of the cantilever 31. The second driving assembly is arranged at the other end of the cantilever 31 and is used to drive the cantilever 31 to move along the inner side wall of the quartz crucible. The specific form of the second driving assembly 33 is not limited. In this embodiment, the second driving assembly 33 is specifically a linear motor module, which is fixed on the base 50 along the length of the cantilever 31. The linear motor module realizes the linear motion of the load through the combination of each unit and has accurate positioning. The linear motor module is a prior art and its specific structure will not be elaborated here. One end of the cantilever 31 away from the vibration platform 10 is fixed on the sliding table of the linear motor module. The two pneumatic hammers 32 arranged in opposite directions are both equipped with flat hammers. The two pneumatic hammers 32 knock the side wall of the quartz crucible simultaneously. After knocking a set number of times, the motor controls the sliding table to drive the cantilever 31 to move a set distance along the inner side wall of the quartz crucible, and the pneumatic hammers 32 continue to knock. The cantilever 31 drives the pneumatic hammers 32 to move from the opening of the quartz crucible to the bottom of the quartz crucible. The pneumatic hammers 32 knock out two opposite grooves at the relative positions on the side wall of the quartz crucible and generate several cracks.

[0052] Specifically, as Figure 5As shown in the figure, the vibrating platform 10 includes a supporting platform 11 and a vibrating motor 12. The supporting platform 11 is arranged at the bottom of the clamping assembly 20 for supporting the carbon-carbon crucible, and the vibrating motor 12 is arranged at the bottom of the supporting platform 11. In this embodiment, the supporting platform 11 is arranged on the base 50, in the middle of the relatively arranged clamping assemblies 20. A spring shock absorber 13 is fixedly connected to the bottom of the supporting platform 11 and the base 50. Support blocks 14 are symmetrically and fixedly arranged on the supporting platform 11 at positions corresponding to the clamping assembly 20. The support blocks 14 are adapted to the outer side wall of the carbon-carbon crucible for supporting the outer side wall of the carbon-carbon crucible. After the pneumatic hammer 32 finishes knocking on the quartz crucible, the vibrating motor 12 is started to drive the carbon-carbon crucible to vibrate, so that the quartz crucible breaks and falls off.

[0053] Preferably, as Figure 1 shown in the figure, in order to prevent debris from splashing during the knocking and vibrating processes, a protective plate 40 is arranged on one side of the vibrating platform 10 close to the knocking assembly 30, and the knocking assembly 30 is arranged through the protective plate 40. In this embodiment, the protective plate 40 is fixed on the base 50 and covers the opening side of the carbon-carbon crucible. Through holes are formed in the protective plate 40, and one end of the cantilever 31 provided with the pneumatic hammer 32 passes through the through holes. In order to be able to observe the breaking situation, an observation window 41 is formed in the protective plate 40.

[0054] A method for breaking a quartz crucible, using the quartz crucible breaking device as described above, includes the following steps:

[0055] S1: Place the carbon-carbon crucible with the quartz crucible on the vibrating platform 10;

[0056] Use a manipulator to place the carbon-carbon crucible with the quartz crucible on the supporting platform 11. The central axis of the carbon-carbon crucible is parallel to the supporting platform 11, so that the outer side wall of the carbon-carbon crucible is placed on the support blocks 14, and the opening of the carbon-carbon crucible faces the knocking assembly 30.

[0057] S2: The clamping assembly 20 clamps the carbon-carbon crucible;

[0058] The driving cylinder 23 extends to drive the clamping bracket 21 and the rotating shaft 221 to rotate towards the vibrating platform 10, so that the clamping bracket 21 drives the clamping plate 24 to move towards the vibrating platform 10. When the bottom of the clamping bracket 21 abuts against the limit block 226, the driving cylinder 23 stops extending, and the clamping bracket 21 is in a vertical state. The locking cylinder 227 extends to lock the clamping bracket 21. The first driving assembly 25 drives the clamping plate 24 to move towards the carbon-carbon crucible to clamp the carbon-carbon crucible. The first driving assembly 25 drives the guide shaft 26 to move along the sleeve 27 through the clamping plate 24. The guide shaft 26 plays a guiding role to prevent the clamping plate 24 from being skewed and affecting the clamping effect.

[0059] S3: The knocking component 30 moves along the inner wall of the quartz crucible, knocking on the inner wall of the quartz crucible until it reaches the arc at the bottom of the quartz crucible;

[0060] The second driving component 33 drives the oppositely arranged pneumatic hammers 32 to move into the quartz crucible through the cantilever 31. The oppositely arranged pneumatic hammers 32 knock on the inner wall of the quartz crucible. After knocking a set number of times, the second driving component 33 drives the pneumatic hammers 32 to move a set distance along the inner wall of the quartz crucible and then continue knocking. Repeat the above steps until reaching the arc at the bottom of the quartz crucible, forming two opposite grooves on the inner wall of the quartz crucible. At the same time, several cracks with uncertain sizes and positions are generated around the grooves, and the internal stress of the quartz crucible is released at the grooves and cracks. The knocking component 30 exits the quartz crucible and resets.

[0061] S4: The vibration platform 10 drives the carbon-carbon crucible to vibrate, causing the quartz crucible to separate from the carbon-carbon crucible;

[0062] The vibration motor 12 at the bottom of the support platform 11 starts vibrating according to the set duration. After continuously vibrating with a strong excitation force for a period of time, the quartz crucible first breaks from the grooves and cracks with weak strength, and then under continuous vibration, the quartz crucible without internal stress support falls off from the carbon-carbon crucible.

[0063] During the knocking and vibration processes, the protection plate 40 can prevent broken quartz from splashing, and the staff can observe the breaking situation through the observation window 41.

[0064] S5: The manipulator pours out the broken quartz crucible from the carbon-carbon crucible;

[0065] After the quartz crucible is broken, the first driving component 25 drives the clamping plate 24 away from the carbon-carbon crucible, releasing the carbon-carbon crucible. The locking cylinder 227 contracts and disengages from the clamping bracket 21. The driving cylinder 23 contracts and drives the clamping bracket 21 to rotate away from the vibration platform 10, causing the clamping bracket 21 to drive the clamping plate 24 to move away from the vibration platform 10. The manipulator clamps the carbon-carbon crucible and pours the broken quartz crucible in the carbon-carbon crucible into the waste collection box.

[0066] The advantages and positive effects of the present utility model are:

[0067] 1. By setting the knocking component and the vibration platform, the automatic breaking of the quartz crucible is realized by knocking and vibrating, ensuring the breaking effect, reducing the working intensity, reducing safety hazards, and improving work efficiency;

[0068] 2. Using pneumatic hammers arranged oppositely to knock on the quartz crucible ensures the consistency of the knocking force, reduces the damage to the carbon-carbon crucible, and extends the service life of the carbon-carbon crucible;

[0069] 3. By setting the clamping assembly, during the crushing process, the carbon-carbon crucible is clamped, which not only ensures the normal progress of the crushing process but also avoids the detachment of the carbon-carbon crucible.

[0070] The above has described the embodiments of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
