Bubble-proof crucible moving device for sapphire crystal growth

Abstract

This invention relates to the field of crucible movement technology, specifically to an anti-bubble crucible movement device for sapphire crystal growth. The device includes a main body with slide rails on both sides. A support is slidably connected to both slide rails. When moving the crucible, the invention uses a threaded rod for low-speed drive, allowing the crucible to move synchronously with the internal melt, reducing melt disturbance and preventing air ingress and bubble formation from the source, thus ensuring melt purity. After the crucible reaches the settling position, it rotates at low speed via an electric telescopic rod and rack and pinion transmission, balancing the melt temperature and viscosity, peeling off bubbles adhering to the wall surface, and clearing the bubble's upward path. Simultaneously, a mechanical structure switches the negative pressure channel, using low negative pressure to cause surface bubbles to burst and draw deeper bubbles to the surface. Through the crucible's rotation and negative pressure working together to remove bubbles, the overall defoaming efficiency during settling can be improved.

Description

Technical Field

[0001] This invention relates to the field of crucible moving technology, specifically to an anti-bubble crucible moving device for sapphire crystal growth. Background Technology

[0002] The crucible is a core high-temperature resistant container used in the high-temperature preparation of sapphire crystals. It holds alumina raw materials, supports the high-temperature melt, and facilitates the melting of raw materials, degassing of the melt, and directional crystal growth. This component is typically made of high-temperature resistant special metals such as molybdenum and tungsten, capable of withstanding the ultra-high temperature environment required for crystal growth. It provides a sealed and stable space for raw material melting, melt homogenization, and crystal formation, making it an indispensable core component throughout the entire sapphire crystal growth process.

[0003] Currently, in the field of sapphire crystal melt preparation and production, traditional crucible mobile equipment only uses a single threaded drive structure to realize the multi-workstation displacement and transportation of crucibles. The equipment function is relatively simple, and it can only complete the transfer operation of crucibles. It cannot integrate the supporting auxiliary degassing function at the static station. The melt can only rely on natural static placement to expel air. The autonomous degassing is difficult to quickly remove the tiny bubbles inside the melt and the bubbles attached to the crucible wall. There are defects such as incomplete degassing and long degassing cycle. The overall degassing efficiency is low, which greatly delays the progress of the production process and makes it difficult to meet the needs of high-efficiency and high-purity large-scale production and processing of high-quality sapphire crystals. Summary of the Invention

The melt can only rely on natural settling to release air, and the self-venting is difficult to quickly remove the tiny bubbles inside the melt and the bubbles attached to the crucible wall. There are defects such as incomplete defoaming, long venting cycle, low overall defoaming efficiency, which greatly delays the progress of the production process and makes it difficult to meet the needs of high-efficiency and high-purity large-scale production and processing of high-quality sapphire crystals.

[0007] Preferably, a drive gear is rotatably connected to the bracket, and multiple fixed plates are fixedly connected inside the drive gear. Multiple torsion spring shafts are installed on the rotating rod, and rotating plates are installed on each of the multiple torsion spring shafts. Multiple blocking members are fixedly connected to the outer wall of the rotating rod, and the multiple blocking members respectively contact the corresponding rotating plates.

[0008] Preferably, a second electric telescopic rod is fixedly connected to the outer wall of the bracket, a rack is slidably connected to the outer wall of the bracket, the rack meshes with the driving gear, the end of the second electric telescopic rod is fixedly connected to the outer wall of the rack, and a driven gear is fixedly sleeved on the rotating tube, the driven gear meshes with the driving gear.

[0009] Preferably, the maintenance mechanism includes a storage cavity fixedly connected to a bracket, a liquid filling port on the storage cavity, a bottom cylinder connected to the bottom of the storage cavity, a one-way valve at the upper end of the bottom cylinder, an oil outlet pipe connected to the bottom of the bottom cylinder, a lubricating element connected to the bottom of the oil outlet pipe, a plurality of extrusion holes on the lubricating element, and scrapers fixedly connected to both sides of the lubricating element.

[0010] Preferably, the bottom cylinder has two sliding members that slide through it, and the ends of the two sliding members are fixedly connected to a piston. The piston has a feed hole, and a torsion spring limiting shaft is installed on the outer side wall of the piston. An oil baffle is fixedly connected to the torsion spring limiting shaft.

[0012] Preferably, side plates are fixedly connected to both sides of the mounting chassis, electric rods are fixedly connected to the side plates, and clamping components are fixedly connected to the ends of the electric rods.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a threaded rod is used to drive the crucible at low speed during transfer, so that the crucible and the internal melt move synchronously, reducing melt disturbance and preventing air intake and foaming from the source, thus ensuring the purity of the melt. After the crucible reaches the settling position, the electric telescopic rod and rack and pinion drive realize the crucible's low-speed rotation, equalize the temperature and viscosity of the melt, peel off the bubbles attached to the wall, and clear the path for the bubbles to float. At the same time, the mechanical structure switches the negative pressure channel, using low negative pressure to cause the surface bubbles of the melt to break and pull the deep bubbles to float. By defoaming the crucible with the rotation of the crucible and the negative pressure, the overall defoaming efficiency during settling can be improved.

[0014] 2. This invention adds a pre-dust removal and lubrication process, which effectively improves transmission stability and equipment service life. During the crucible movement, the negative pressure structure can clean dust and impurities on the surface of the threaded rod in time, preventing debris from entering the thread gap and causing failure. At the same time, the automatic lubrication mechanism delivers the lubricating medium through piston extrusion, and the unidirectional structure ensures stable oil supply. Following the process of dust removal before oiling, it prevents dust and grease from mixing and forming sludge. The lubricating medium can reduce the frictional resistance of the thread, delay component wear, improve problems such as transmission jamming and displacement, stabilize the crucible movement accuracy and uniformity, ensure the stable operation of the melt processing process, reduce equipment maintenance costs, and improve the long-term continuous operation performance of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1 - Figure 15 A bubble-proof crucible moving device for sapphire crystal growth includes a main body 1. Slide rails 3 are provided on both sides of the main body 1, and a support 6 is slidably connected to both slide rails 3. A drive motor 2 is fixedly connected to the outer wall of the main body 1. A threaded rod 5 is installed at the output end of the drive motor 2, and a driving component 20 is threaded onto the threaded rod 5. The driving component 20 is fixedly connected to the support 6. A bubble-removing mechanism and a curing mechanism are provided on the support 6. The bubble-removing mechanism includes a flow box 7 fixedly connected to the support 6. The upper part is connected to a suction component 8, which is equipped with a negative pressure suction pump. The upper part of the flow box 7 is connected to a suction channel 14, and the end of the suction channel 14 is equipped with a dust suction ring 13. The dust suction ring 13 has a dust suction groove 15 inside. The interior of the flow box 7 is connected to a side tube 16, and a rotating tube 17 is rotatably connected to the side tube 16. The end of the rotating tube 17 is connected to a suction plate 34. The bracket 6 is rotatably connected to a rotating rod 41, and the end of the rotating rod 41 is fixedly connected to a mounting base 32. A crucible 33 is mounted on the mounting base 32.

[0019] Inside the circulation box 7, a baffle 12 and a slide plate 9 are slidably connected. A through hole 10 is provided on the slide plate 9. A moving rod 19 is fixedly connected between the baffle 12 and the slide plate 9. A roller 4 is rotatably connected to the moving rod 19. A pressing spring 11 is fixedly connected to the bottom of the moving rod 19. The other end of the pressing spring 11 is fixedly connected to the outer wall of the circulation box 7. A wedge-shaped piece 18 is fixedly connected to the outer wall of the rotating tube 17.

[0020] A drive gear 37 is rotatably connected to the bracket 6. Multiple fixed plates 42 are fixedly connected inside the drive gear 37. Multiple torsion spring shafts are installed on the rotating rod 41. Each torsion spring shaft is equipped with a rotating plate 43. Multiple blocking parts 44 are fixedly connected to the outer wall of the rotating rod 41. Each blocking part 44 contacts the corresponding rotating plate 43.

[0021] A second electric telescopic rod 40 is fixedly connected to the outer wall of the bracket 6. A rack 39 is slidably connected to the outer wall of the bracket 6. The rack 39 meshes with the driving gear 37. The end of the second electric telescopic rod 40 is fixedly connected to the outer wall of the rack 39. A driven gear 38 is fixedly sleeved on the rotating tube 17. The driven gear 38 meshes with the driving gear 37.

[0022] In this embodiment, when it is necessary to move the crucible 33, the drive motor 2 can be turned on to drive the threaded rod 5 to rotate slowly. Since the drive component 20 is threaded onto the threaded rod 5, when the threaded rod 5 rotates, the drive component 20 will drive the entire bracket 6 and the crucible 33 fixedly installed on the mounting base 32 to move slowly along the slide rail 3. The melt inside the crucible 33 usually has a certain viscosity. If the moving speed is too fast, the melt and the inner wall of the crucible 33 will generate violent relative friction. At the same time, the melt will form a local negative pressure due to uneven flow rate. External air is easily drawn into the melt to form bubbles. Moving the crucible 33 slowly can keep the crucible 33 and the internal melt moving synchronously, greatly reducing the relative displacement between the two and the internal disturbance of the melt, ensuring that the melt is in a stable static or slow flow state, eliminating the generation of bubbles from the source, and ensuring the purity of the melt and the accuracy of subsequent processing.

[0023] When the threaded rod 5 rotates, the entire bracket 6 moves slowly along the slide rail 3, which also drives the flow box 7 to move synchronously. At this time, the negative pressure suction pump inside the flow box 7 starts, and the negative pressure generated inside the entire flow box 7 is transmitted to the dust collection ring 13 through the suction channel 14. Then, the dust collection groove 15 sucks and cleans the part of the threaded rod 5 that the driving component 20 is about to contact. By sucking and cleaning the threaded rod 5, external dust and impurities can be prevented from entering the thread gap between the driving component 20 and the threaded rod 5, so as to prevent affecting the smoothness and accuracy of the transmission of the threaded rod 5, thereby ensuring the uniformity of the movement of the crucible 33.

[0024] When the entire support 6 moves the crucible 33 to the middle part of the main body 1 of the equipment, i.e., the static defoaming station, the drive motor 2 is turned off, so that the threaded rod 5 stops rotating. At this time, the second electric telescopic rod 40 can be controlled to slowly retract. When the second electric telescopic rod 40 slowly retracts, it will drive the rack 39 to slowly move towards the drive gear 37. Since the rack 39 and the drive gear 37 are meshed, when the rack 39 moves slowly, it will drive the drive gear 37 to slowly rotate 360 ​​degrees clockwise. When the drive gear 37 slowly rotates clockwise, it will drive the fixed plate 42 to rotate synchronously. Since the clockwise rotation direction of the rotating plate 43 is limited by the blocking part 44, when the fixed plate 42 rotates clockwise with the drive gear 37, pushing the rotating plate 43 to rotate clockwise, it will drive the entire rotating rod 41 to slowly rotate. When the rotating rod 41 rotates slowly, it drives the crucible 33 to rotate slowly through the mounting base 32. The slow rotation of the crucible 33 ensures that the melt inside the crucible 33 is heated evenly, avoiding uneven melt viscosity caused by local temperature differences. It provides a stable upward channel for the tiny bubbles that have been generated inside the melt, promoting the rapid aggregation of bubbles and their rise to the surface of the melt, thus greatly improving the defoaming efficiency. At the same time, the slow rotation of the crucible 33 causes the melt to form a gentle circumferential flow, which can easily peel off the tiny bubbles that are adhering to the inner wall and bottom corners of the crucible 33, allowing them to merge into the mainstream of the melt and float upward, improving the efficiency of static defoaming. (It should be noted that the rotation speed of the crucible 33 is very slow, which can effectively avoid violent disturbance of the melt due to centrifugal force, prevent new air from being drawn into the melt and generating new bubbles, and also prevent the melt from splashing, ensuring the stability and reliability of the defoaming process.)

[0025] Since the driving gear 37 and the driven gear 38 are meshed and their gear ratio is 1:2, when the driving gear 37 rotates 360 degrees clockwise, it will drive the driven gear 38 to rotate 180 degrees counterclockwise. When the driven gear 38 rotates 180 degrees counterclockwise, it will drive the rotating tube 17 to rotate 180 degrees synchronously, thus causing the drawing plate 34 to deflect 180 degrees, positioning it directly above the crucible 33. When the rotating tube 17 rotates 180 degrees, it will also drive the wedge-shaped component 18 to rotate synchronously, and the wedge-shaped component 18 rotates accordingly. When tube 17 rotates 180 degrees counterclockwise, it contacts and pushes roller 4, causing the entire moving rod 19 to move downward against the elastic force of pressing spring 11. When the moving rod 19 moves downward, it will drive baffle 12 and slide plate 9 to move downward synchronously. When baffle 12 moves downward, it will block the opening of suction channel 14, so that the negative pressure suction force generated by the negative pressure suction pump will no longer flow through suction channel 14. Because the entire bracket 6 is in a stopped state at this time, there is no need to clean the threaded rod 5, which can avoid the waste of negative pressure and improve the efficiency of negative pressure utilization.

[0026] When the slide plate 9 moves down synchronously, the through hole 10 will enter the flow box 7. When the through hole 10 replaces the unopened part of the slide plate 9 and enters the flow box 7, it no longer blocks the opening end of the side tube 16. At this time, the negative pressure suction force generated by the negative pressure suction pump will flow through the through hole 10 and then through the side tube 16. When the side tube 16 has suction force, the rotating tube 17 and the suction plate 34 will also have suction force. When the suction plate 34 has suction force, it will suck the melt inside the crucible 33. The negative pressure environment above the melt can increase the pressure difference between the inside and outside of the surface bubbles, causing the surface bubbles to expand and burst quickly, avoiding the accumulation and retention of bubbles. At the same time, a pressure gradient from top to bottom is formed, which generates an upward pulling force on the tiny bubbles inside the melt, overcomes the viscous resistance of the melt, accelerates the floating speed of the bubbles, and improves the efficiency of settling and defoaming (it should be noted that the negative pressure suction force of the suction plate 34 is precisely controlled and kept at a low level, so as not to cause melt splashing, nor to disrupt the stable flow state of the melt due to excessive suction).

[0027] When the crucible 33 stays in the middle of the main body 1 for a long time, and the foam inside the crucible 33 is defoamed, the operator can control the second electric telescopic rod 40 to slowly extend. When the second electric telescopic rod 40 slowly extends, it will push the rack 39 to move away from the drive gear 37. At this time, the drive gear 37 will rotate 360 ​​degrees counterclockwise. When the drive gear 37 drives the fixed plate 42 to rotate counterclockwise, the fixed plate 42 will contact and push the rotating plate 43 to rotate counterclockwise. Since there is no blocking part 44 to limit the counterclockwise rotation of the rotating plate 43, when the fixed plate 42 rotates counterclockwise, it will cause the rotating plate 43 to deflect counterclockwise, and will not drive the rotating rod 41 to rotate through the rotating plate 43. When the rotating rod 41 stops rotating, it will not drive the crucible 33 to rotate through the mounting base 32.

[0028] When the driving gear 37 rotates counterclockwise 360 ​​degrees, it drives the driven gear 38 to rotate clockwise 180 degrees. When the driven gear 38 rotates clockwise 180 degrees, it also drives the rotating tube 17 to rotate synchronously. At this time, the wedge 18, driven by the rotating tube 17, will flip back to its original position and no longer press the shift rod 19. Then, under the elastic force of the pressing spring 11, the shift rod 19 will drive the baffle 12 and the slide plate 9 back to their original positions. When the baffle 12 returns to its original position, it no longer blocks the air intake channel 14. When the slide plate 9 returns to its original position, the unopened part of the slide plate 9 will again block the open end of the side tube 16. The side tube 16 no longer generates suction, while the suction channel 14 will generate suction again, allowing the suction ring 13 to regain its suction capability, preparing for the subsequent displacement of the bracket 6. When the rotating tube 17 rotates 180 degrees to reset, it will cause the suction plate 34 to deflect back to its original position, no longer located directly above the crucible 33. After the entire crucible 33 has settled and defoamed, the drive motor 2 can be turned on again to drive the threaded rod 5 to rotate slowly, causing the entire bracket 6 and the crucible 33 fixedly mounted on the mounting base 32 to move slowly along the slide rail 3 to the front end of the main body 1 for subsequent operations.

[0029] Example 2: Please refer to Figure 1 - Figure 15 The maintenance mechanism includes a storage cavity 21 fixedly connected to the bracket 6. The storage cavity 21 is provided with a liquid filling port. The bottom of the storage cavity 21 is connected to a bottom cylinder 24. A one-way valve is provided at the upper end of the bottom cylinder 24. An oil outlet pipe 45 is connected to the bottom of the bottom cylinder 24. A lubricating component 22 is connected to the bottom of the oil outlet pipe 45. The lubricating component 22 is provided with multiple extrusion holes 27. Scrapers 23 are fixedly connected to both sides of the lubricating component 22.

[0030] The bottom cylinder 24 has two sliding parts 26 that slide through it. The ends of the two sliding parts 26 are fixedly connected to a piston 28. The piston 28 has a feed hole 29. A torsion spring limiting shaft 31 is installed on the outer wall of the piston 28. An oil baffle 30 is fixedly connected to the torsion spring limiting shaft 31.

[0031] Both sides of the storage cavity 21 are fixedly connected to a first electric telescopic rod 25, and the end of the first electric telescopic rod 25 is fixedly connected to the end of the sliding member 26.

[0032] Side plates 36 are fixedly connected to both sides of the mounting chassis 32. Electric rods are fixedly connected to the side plates 36, and clamping parts 35 are fixedly connected to the ends of the electric rods.

[0033] In this embodiment, while the threaded rod 5 rotates, causing the entire bracket 6 to move slowly, if friction jamming is detected in the threaded rod 5, the first electric telescopic rod 25 can be controlled to reciprocate. When the first electric telescopic rod 25 reciprocates, it will push the piston 28 to move up and down in the bottom cylinder 24 through the sliding member 26. During this process, the lubricating oil inside the storage chamber 21 will be continuously transported unidirectionally into the bottom cylinder 24. When the piston 28 moves upward into the bottom cylinder 24 under the action of the sliding member 26, the space above the piston 28 is compressed. Under the pressure, the lubricating oil in this space is forced through the feed hole 29 to open the oil baffle 30, which can only be opened in one direction, and flows into the space below the piston 28. When the lubricating oil reaches the bottom of the piston 28, the piston 28 moves downward under the action of the sliding member 26. When the piston 28 is in motion, it continuously compresses the space below the piston 28. At this time, the lubricating oil below the piston 28 flows into the lubricating component 22 through the oil outlet pipe 45, and then is squeezed onto the surface of the threaded rod 5 through multiple extrusion holes 27. The scraper 23 on the lubricating component 22 scrapes the lubricating oil evenly and applies it into the thread groove of the threaded rod 5. Since the lubricating component 22 is located in front of the driving component 20, and the dust suction groove 15 is located in front of the lubricating component 22, after the dust suction groove 15 sucks and cleans the dust and debris on the threaded rod 5, the lubricating component 22 then lubricates. This can prevent impurities on the surface of the threaded rod 5 from mixing with the lubricating oil to form sludge, and prevent sludge from entering the threaded pair gap and affecting the lubrication effect. By lubricating the threaded rod 5, jamming of the threaded rod 5 during transmission can be avoided, thereby ensuring the smooth movement of the crucible 33 mounted on the bracket 6.

[0034] It should be noted that a one-way valve is installed inside the bottom cylinder 24, so the lubricating oil inside the storage chamber 21 can only enter the bottom cylinder 24 downwards. When the piston 28 pushes upwards, it will not flow back into the storage chamber 21 through the bottom cylinder 24. At the same time, when the piston 28 moves downwards, the downward pressure will push the oil baffle 30 to flip and block the feed hole 29. The initial state inside the bottom cylinder 24 is as follows. Figure 10 As shown, the oil baffle 30 is tightly attached to the bottom of the bottom cylinder 24, firmly blocking the feed hole 29. At this time, the lubricating oil inside the bottom cylinder 24 will not leak down through the feed hole 29, ensuring that the lubricating oil can be used entirely for the lubrication of the threaded rod 5, thereby improving the lubricating oil utilization rate.

[0035] It should be noted that there is an openable dust cover at the rear of the suction component 8. When the inside of the suction component 8 continues to be full of dust, the inside of the suction component 8 can be cleaned by opening the dust cover.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
