Description

Technical Field

[0001] This invention belongs to the technical field of single crystal furnace equipment, and in particular relates to a quartz crucible crushing device and method. Background Technology

[0002] In the single crystal pulling process, the thermal field is the core component for single crystal growth. The proper use of the thermal field can effectively improve the crystal formation of the single crystal furnace. Because quartz crucibles may experience crystallization, local bulging, bending, and other deformation problems during use, in order to prevent leakage after prolonged crystal pulling, the quartz crucible inside the carbon-carbon crucible usually needs to be removed and replaced after one batch of single crystals is pulled.

[0003] During dismantling, the quartz crucible cannot be directly removed because it is in close contact with the carbon-carbon crucible. Typically, a hammer is used to manually break the quartz crucible. However, this method results in inconsistent striking force, easily damaging the carbon-carbon crucible. Furthermore, manual labor is physically demanding, inefficient, and poses safety hazards. Summary of the Invention

In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0049] like Figure 1 As shown, an embodiment of the present invention discloses a quartz crucible crushing device, comprising a base 50, on which a vibrating platform 10, a clamping assembly 20, and a striking assembly 30 are mounted. The base 50 is welded from steel pipes and steel plates, and can be integrally installed or separately fixedly connected. A heavy-duty foot cup is installed at the bottom of the base 50. The vibrating platform 10 is used to place a carbon-carbon crucible containing a quartz crucible. The central axis of the carbon-carbon crucible is parallel to the vibrating platform 10, so that the outer wall of the carbon-carbon crucible rests on the vibrating platform 10. The clamping assembly 20 is disposed on opposite sides of the vibrating platform 10 to clamp the outer side of the carbon-carbon crucible. The striking assembly 30 is disposed on the side of the vibrating platform 10 where the clamping assembly 20 is not located. When the carbon-carbon crucible is placed, the top opening of the carbon-carbon crucible faces the striking assembly 30. The striking assembly 30 can move along the inner wall of the quartz crucible, striking the inner wall of the quartz crucible to crush it.

[0050] Specifically, such 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. A clamping plate 24 is provided on the top side of the clamping bracket 21 near the carbon crucible. The clamping base 22 is located at the bottom of the clamping bracket 21 and is rotatably connected to it. The driving cylinder 23 is located on the side of the clamping bracket 21 away from the carbon crucible, and can drive the clamping bracket 21 to rotate closer to or further away from the vibration platform 10, making it easier to handle the carbon crucible. The fixed end of the driving cylinder 23 is hinged to the clamping base 22, and the movable end is hinged to the upper part of the clamping bracket 21. When the driving cylinder 23 retracts, it drives the clamping bracket 21 to rotate away from the vibration platform 10, causing the clamping bracket 21 to move the clamping plate 24 away from the vibration platform 10. When the driving cylinder 23 extends, it drives the clamping bracket 21 to rotate towards the vibration platform 10, causing the clamping bracket 21 to move the clamping plate 24 towards the vibration platform 10. The clamping bracket 21 is made of welded profiles. The shape of the clamping plate 24 is not limited. In this embodiment, the clamping plate 24 is a rectangular plate. A first abutment plate 241 is obliquely fixed on the upper part of the clamping plate 24 to abut the side wall of the carbon crucible. A second abutment plate 242 is obliquely fixed on one end of the clamping plate 24 to abut the bottom of the carbon crucible, which is more conducive to the clamping and fixing of the carbon crucible.

[0051] Specifically, the clamping base 22 is provided with a rotating shaft 221, and the bottom of the clamping bracket 21 is connected to the rotating shaft 221. In this embodiment, the clamping base 22 includes a base plate 222, which is fixedly connected to the base 50. A support column 223 is fixed on the upper part of the base plate 222, and a mounting plate 224 is fixed on the upper part of the support column 223. The two 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 fixed to the rotating shaft 221 by a connecting seat 228. The fixed end of the drive cylinder 23 is hinged to the base plate 222, and drives the rotating shaft 221 at the bottom of the support bracket to rotate through telescopic movement. A limit block 226 is fixed on the side of the rotating shaft 221 away from the drive cylinder 23. The limit block 226 is fixed on the mounting plate 224. When the drive cylinder 23 extends and the clamping bracket 21 rotates toward the vibration platform 10, the bottom of the support bracket abuts against the limit block 226, and the drive cylinder 23 stops extending. At this time, the support bracket is in a vertical state.

[0052] Preferably, locking cylinders 227 are provided on both sides of the clamping bracket 21, and the locking cylinders 227 are mounted on the clamping base 22. To prevent the clamping bracket 21 from moving and failing to clamp the carbon crucible, thus affecting the breakage of the quartz crucible, when the clamping bracket 21 rotates to a vertical position, the locking cylinders 227 on both sides extend and abut against both sides of the clamping bracket 21, locking the clamping bracket 21. In this embodiment, the locking cylinders 227 are fixed on the mounting plate 224 on the side near the drive cylinder 23.

[0053] Specifically, a first drive assembly 25 is provided on the top of the clamping bracket 21. The first drive 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 move closer to or away from the carbon-carbon crucible. The specific form of the first drive assembly 25 is not limited. In this embodiment, the first drive assembly 25 is specifically a turbine screw structure. The turbine screw structure is fixed on the clamping bracket 21, the screw is set perpendicular to the clamping plate 24, and its end is fixedly connected to the side of the clamping plate 24 away from the carbon-carbon crucible. A motor drives the turbine to rotate, causing the screw to move horizontally, thereby driving the clamping plate 24 to move closer to or away from the carbon-carbon crucible. The turbine screw structure is prior art and will not be described in detail here.

[0054] Preferably, a guide shaft 26 is provided on the side of the clamping plate 24 away from the carbon crucible, and the guide shaft 26 is movably connected to the clamping bracket 21. The number of guide shafts 26 is not limited. In this embodiment, guide shafts 26 are fixed at both ends of the clamping plate 24, and the guide shafts 26 are perpendicular to the clamping plate 24. A sleeve 27 is fixed at the top of the clamping bracket 21 corresponding to the position of the guide shaft 26, and the guide shaft 26 and the sleeve 27 are clearance-fitted. The first driving assembly 25 can drive the guide shaft 26 to move along the sleeve 27 via the clamping plate 24.

[0055] Specifically, such as Figure 4 As shown, the striking assembly 30 includes a cantilever 31, two air hammers 32 facing away from each other, and a second drive assembly 33. The cantilever 31 is horizontally arranged along the inner wall of the quartz crucible. The air hammers 32 facing away from each other are located at one end of the cantilever 31 near the vibration platform 10. The two air hammers 32 are fixed to the ends of the cantilever 31 facing away from each other. The second drive assembly is located at the other end of the cantilever 31 and is used to drive the cantilever 31 to move along the inner wall of the quartz crucible. The specific form of the second drive assembly 33 is not limited. In this embodiment, the second drive assembly 33 is specifically a linear motor module, which is fixed to the base 50 along the length of the cantilever 31. The linear motor module achieves linear motion of the load through the combination of various units, with precise positioning. The linear motor module is existing technology, and its specific structure will not be described in detail here. The end of the cantilever 31 away from the vibration platform 10 is fixed to the slide of the linear motor module. Both air hammers 32 facing away from each other are equipped with a straight hammer head. Two air hammers 32 simultaneously strike the side wall of the quartz crucible. After a set number of strikes, the motor-controlled slide moves the cantilever 31 a set distance along the inner side wall of the quartz crucible, and the air hammers 32 continue striking. The cantilever 31 moves the air hammers 32 from the opening of the quartz crucible to the bottom of the quartz crucible. The air hammers 32 strike two opposing grooves and create several cracks at relative positions on the side wall of the quartz crucible.

[0056] Specifically, such as Figure 5As shown, the vibration platform 10 includes a support platform 11 and a vibration motor 12. The support platform 11 is located at the bottom of the clamping assembly 20 and is used to support the carbon-carbon crucible. The vibration motor 12 is located at the bottom of the support platform 11. In this embodiment, the support platform 11 is located on the base 50, in the middle of the clamping assembly 20. A spring shock absorber 13 is fixed to the bottom of the support platform 11 and connected to the base 50. Support blocks 14 are symmetrically fixed on the support platform 11 relative to the clamping assembly 20. The support blocks 14 are adapted to the outer wall of the carbon-carbon crucible and are used to support the outer wall of the carbon-carbon crucible. After the air hammer 32 finishes striking the quartz crucible, the vibration motor 12 starts, causing the carbon-carbon crucible to vibrate, causing the quartz crucible to break and fall off.

[0057] Preferred, such as Figure 1 As shown, to prevent fragments from flying during impact and vibration, a protective plate 40 is provided on the side of the vibration platform 10 near the impact assembly 30, through which the impact assembly 30 passes. In this embodiment, the protective plate 40 is fixed to the base 50 and covers the open side of the carbon crucible. A through hole is provided on the protective plate 40, through which one end of the cantilever 31 with the air hammer 32 passes. An observation window 41 is provided on the protective plate 40 to allow observation of the breakage process.

[0058] A method for crushing a quartz crucible, using the quartz crucible crushing device described above, includes the following steps:

[0059] S1: Place the carbon crucible with the quartz crucible on the vibration platform 10;

[0060] A robotic arm is used to place a carbon-carbon crucible with a quartz crucible onto a support platform 11. The central axis of the carbon-carbon crucible is parallel to the support platform 11, and the outer wall of the carbon-carbon crucible is placed on a support block 14. The opening of the carbon-carbon crucible faces the striking assembly 30.

[0061] S2: Clamping assembly 20 clamps the carbon crucible;

[0062] The extension of the drive cylinder 23 causes the clamping bracket 21 and the rotating shaft 221 to rotate toward the vibration platform 10, making the clamping bracket 21 move the clamping plate 24 toward the vibration platform 10. When the bottom of the clamping bracket 21 abuts against the limiting block 226, the drive cylinder 23 stops extending, and the clamping bracket 21 is in a vertical position. The locking cylinder 227 extends to lock the clamping bracket 21. The first drive assembly 25 drives the clamping plate 24 to move toward the carbon-carbon crucible, clamping the carbon-carbon crucible. The first drive 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 tilting and affecting the clamping effect.

[0063] S3: The striking component 30 moves along the inner wall of the quartz crucible and strikes the inner wall of the quartz crucible until it strikes the arc at the bottom of the quartz crucible.

[0064] The second drive assembly 33, via the cantilever 31, moves the opposing air hammer 32 into the quartz crucible. The opposing air hammer 32 strikes the inner wall of the quartz crucible a set number of times. After this, the second drive assembly 33 moves the air hammer 32 a set distance along the inner wall of the quartz crucible and continues striking, repeating the above steps until it strikes the arc at the bottom of the quartz crucible. This forms two opposing grooves on the inner wall of the quartz crucible, while simultaneously creating several cracks of uncertain size and location around the grooves. The internal stress of the quartz crucible is released at the grooves and cracks. The striking assembly 30 then retracts from the quartz crucible and resets.

[0065] S4: The vibration platform 10 drives the carbon crucible to vibrate, causing the quartz crucible to detach from the carbon crucible.

[0066] The vibration motor 12 at the bottom of the support platform 11 starts to vibrate according to the set time. After vibrating continuously with a strong excitation force for a period of time, the quartz crucible first breaks off from the weak groove and crack. Then, under continuous vibration, the quartz crucible without internal stress support falls off the carbon crucible.

[0067] During the impact and vibration, the protective plate 40 can prevent quartz fragments from splashing out, and the staff can observe the breakage through the observation window 41.

[0068] S5: The robotic arm pours the broken quartz crucible out of the carbon crucible;

[0069] After the quartz crucible is broken, the first drive assembly 25 moves the clamping plate 24 away from the carbon-carbon crucible, releasing it. The locking cylinder 227 retracts, disengaging from the clamping bracket 21. The drive cylinder 23 retracts, causing the clamping bracket 21 to rotate away from the vibration platform 10, thus moving the clamping bracket 21 and clamping plate 24 away from the vibration platform 10. The robotic arm holds the carbon-carbon crucible and pours the broken quartz crucible inside into the waste collection box.

[0070] The advantages and positive effects of this invention are:

[0071] 1. By setting up a striking component and a vibration platform, the quartz crucible is automatically crushed by striking and vibration, which ensures the crushing effect, reduces the workload, reduces safety hazards, and improves work efficiency;

[0072] 2. Using a pneumatic hammer positioned in opposite directions to strike the quartz crucible ensures consistent striking force, reduces damage to the carbon-carbon crucible, and extends its service life.

[0073] 3. By setting up a clamping component, the carbon crucible is clamped during the crushing process, which not only ensures the normal progress of the crushing process but also prevents the carbon crucible from falling off.

[0074] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
