Description

Technical Field

[0001] This invention belongs to the field of silicon carbide powder preparation, and specifically relates to a silicon carbide powder preparation device and method. Background Technology

[0002] Most semiconductor integrated circuit crystals are grown using the physical vapor transport (PVT) method. The basic principle of crystal growth is to place the raw material at the bottom of a graphite crucible and heat the crucible using the skin effect through an induction coil. Once a certain temperature is reached, the raw material decomposes into gas and volatilizes to the seed crystal area at the top of the crucible. After a series of chemical reactions, SiC is generated and crystallizes on the surface of the seed crystal through a certain axial and radial temperature gradient to obtain single-crystal silicon carbide with a certain structure. In the process of preparing silicon carbide powder, it is often necessary to grind the silicon carbide powder so that the ground silicon carbide powder can meet different production requirements. However, how to improve the grinding efficiency of silicon carbide powder during the grinding preparation process has become an urgent technical problem to be solved.

[0011] As a further improvement of the present invention, the feeding component has a feeding section comprising: Top plate, which is detachably mounted on the chassis; The inner plate is detachably installed inside the top plate, and the inner plate has an annular cavity. An inner ring is arranged inside the top plate. The inner ring and the inner plate form a first clamping cavity. A feeding ring is provided in the first clamping cavity.

[0014] Another technical problem to be solved by the present invention is a method for preparing silicon carbide powder preparation equipment. S1. Feeding silicon carbide powder: Injecting silicon carbide powder into the feeding component; S2. Adjustment of the overall position of the grinding component: By opening the adjustment mechanism, the overall position of the grinding component along the front and back can be adjusted; S3. Grinding and preparation of silicon carbide powder: By turning on the grinding component, the silicon carbide powder in the feeding component can be ground and prepared. S4. Triggering operation of the conductive component: After the grinding component grinds the silicon carbide powder in the feeding component, the grinding component is driven to move downward. On the one hand, this can enhance the grinding effect of the silicon carbide powder in the feeding component, and on the other hand, it can trigger the operation of the conductive component. S5.

After the newly added material enters the annular cavity in the inner disc, it can save the feeding process and feeding time, and can also mix the new material with the old material in the inner disc, allowing it to be fully ground by the grinding disc, further enhancing the grinding efficiency of the grinding disc. At the same time, as the grinding disc continues to move downward, it can also squeeze the wedge block to abut against the outer layer of the contact wheel, causing the outer layer of the contact wheel and the insert rod to move upward, which can push the silicon carbide powder in the second feeding cavity formed between the second conical surface of the second feeding ring and the second inner ring to be injected into the first feeding cavity, and utilize... The first conical surface slides into the annular cavity of the inner disc. As the grinding disc moves downward, the pressure between it and the silicon carbide powder increases, allowing for secondary feeding. This enables a second round of feeding and grinding on top of the initial grinding process, further promoting the mixing and grinding of the new and old silicon carbide powder. This enhances the grinding effect of the silicon carbide powder. Furthermore, during the two grinding processes, the drive wheel simultaneously rotates the connecting shaft inside the feed cylinder. This allows the auger blades to transport the ground silicon carbide powder from the feed cylinder to the annular cavity of the inner disc for further grinding. This secondary grinding and refining process enhances the efficiency of silicon carbide powder preparation and improves the final product quality. Attached Figure Description

[0018] 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.

[0019] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0020] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0021] In the embodiments, by Figure 1-12 Provided is a silicon carbide powder preparation apparatus, comprising: a preparation chamber 1 having a cavity; an adjusting member 2 disposed within the cavity of the preparation chamber 1; a grinding member 3 disposed on the adjusting member 2; a conducting member 4 detachably mounted on the grinding member 3 and triggered when the grinding member 3 descends; and a feeding member 5 consisting of a driving section and a feeding section connected to the driving section, wherein the driving section and the conducting member 4 are interconnected, wherein when the conducting member 4 is triggered by the grinding member 3, it can force the driving section to tend to extend outwards, and after the driving section tends to extend outwards, it can progressively squeeze the feeding section to force the silicon carbide powder in the feeding section into the annular cavity of the feeding section.

[0022] The overall concept of this invention is that, through the arrangement of the feeding component 5, on the one hand, it can apply pressure to the silicon carbide powder as the grinding disc 35 moves downward, enhancing the grinding effect of the silicon carbide powder, and on the other hand, it can perform timely replenishment operations. After the newly added material enters the annular cavity in the inner disc 571, it can save the feeding process and feeding time, and can also mix the new material with the old material in the inner disc 571, and fully grind it through the grinding disc 35, further enhancing the grinding efficiency of the grinding disc 35. At the same time, as the grinding disc 35 continues to move downward, it can also squeeze the wedge block 54 to abut against the outer contact wheel 584, so that the outer contact wheel 584 and the insert rod 583 move upward, which can push the silicon carbide powder in the second feeding cavity formed between the second conical surface of the feeding ring 576 and the inner ring 574 into the first feeding cavity, and utilize... The silicon carbide powder slides down the first conical surface into the annular cavity of the inner disk 571. As the grinding disc 35 moves down, the pressure between it and the silicon carbide powder increases, allowing for secondary grinding. This further promotes the mixing and grinding of the new and old silicon carbide powder by the grinding disc 35, thus enhancing the grinding effect. In addition, during the two grinding processes of the silicon carbide powder by the grinding disc 35, the drive wheel 56 rotates synchronously, driving the connecting shaft 591 inside the feed cylinder 59 to rotate. This allows the auger blade 592 to transport the ground silicon carbide powder from the feed cylinder 59 to the annular cavity of the inner disk 571 to continue being ground by the grinding disc 35, thus performing a secondary grinding and refining process on the silicon carbide powder. This enhances the grinding efficiency and finished product quality of the silicon carbide powder.

[0023] Next, a more specific structure and construction of the adjusting component 2 will be given for further explanation. The adjusting component 2 includes: a left frame 21, which is arranged in the cavity of the preparation box 1; a linear module 22, which is arranged on the left frame 21; a right frame 23, which is arranged in the cavity of the preparation box 1; and a horizontal plate 24, which is detachably arranged on the output end of the linear module 22, and one end of the horizontal plate 24 can slide along the right frame 23. Next, the overall operating principle and effect of the adjusting component 2 will be further explained. By activating the linear module 22, the horizontal plate 24 can be driven to move in the front-back direction, thereby changing the position of the grinding component 3 in the front-back direction. It should also be noted that the horizontal plate 24 is usually not moved in this equipment. That is to say, the front-back, left-back and right-back positions of the grinding component 3 are fixed in the initial state. Only when the grinding component 3 is maintained as a whole, when the linear module 22 is activated, can the front-back position of the horizontal plate 24 and the grinding component 3 be adjusted. At the same time, the position of the rotating shaft 45 on the mounting frame 41 needs to be adjusted synchronously by pulling out the shaft seat, so that the transmission component 4 can follow the grinding component 3 to adjust its left-back position. Under normal conditions, the front-back, left-back and right-back positions of the grinding component 3 and the transmission component 4 are fixed. The rotating shaft 45 runs by rotating within the mounting frame 41. Only when the grinding component 3 is maintained, by releasing the position restriction between the rotating shaft 45 and the mounting frame 41, can the front-back position of the grinding component 3 and the transmission component 4 be adjusted. It should also be noted that the linear module 22 is a known component in the prior art. The linear module 22 is composed of a frame, a lead screw inside the frame, a motor on the frame, and a ball bearing base inside the frame. When the motor is turned on, it can drive the lead screw to rotate, thereby mobilizing the ball bearing base inside the frame to slide.

[0024] Next, a more specific structure and construction of the grinding component 3 will be given for further explanation. The grinding component 3 includes: a first vertical plate 31, which is arranged on the adjusting member 2, and a second linear module 32 is arranged on the first vertical plate 31; a second vertical plate 33, which is detachably installed on the output end of the second linear module 32; a drive motor 34, which is detachably arranged on the second vertical plate 33; and a grinding disc 35, which consists of an upper plate and a lower plate connected to the upper plate. The upper plate is connected to the output end of the drive motor 34, and the lower plate has a slot 36. Next, the overall working principle and effect of the grinding component 3 will be further explained. By turning on the drive motor 34, the grinding disc 35 can be rotated to grind the silicon carbide powder in the feeding component 5. By turning on the linear module 32, the grinding disc 35 can be gradually lowered. On the one hand, the grinding disc 35 can be driven to lower to increase the pressure between the grinding disc 35 and the silicon carbide powder, thereby enhancing the grinding effect of the grinding disc 35 on silicon carbide. On the other hand, when the grinding disc 35 lowers, it can drive the transmission component 4 to activate the transmission component 4, thereby replenishing the silicon carbide powder in the feeding component 5 into the annular cavity. It should also be noted that linear module 2 32 is a known component in the prior art, and has the same mechanical structure as linear module 1 22. Therefore, it will not be described in detail in this embodiment.

[0025] Next, a more specific structure and construction of the transmission component 4 will be given for further explanation. The transmission component 4 includes: a mounting frame 41, which is detachably mounted in the preparation box 1; a side ear 42, which is arranged on the output end of the grinding component 3; a folded ear 43, which is arranged on the side ear 42, and a transmission rod 44 is provided on the folded ear 43, and two sets of balls are provided on the transmission rod 44; a rotating shaft 45, which is rotatably mounted on the mounting frame 41, and a shaft cylinder 46 is provided on the rotating shaft 45, and a spiral groove is provided in the shaft cylinder 46, and the spiral groove allows the balls to slide; a gear 47, which is detachably mounted on the rotating shaft 45, and a belt 48 is sleeved on the gear 47; and a rotating shaft 49, which is rotatably mounted on the mounting frame 41, and a gear 491 is provided on the rotating shaft 49, and the gear 491 is bypassed by the belt 48. Next, the working principle and effect of the transmission component 4 will be further explained. When the vertical plate 2 33 descends, it can drive the folding ear 43 and the transmission rod 44 to descend. When the transmission rod 44 descends, it can drive the ball to descend and move along the direction of the spiral groove, which can drive the shaft cylinder 46 to rotate, thereby driving the gear 1 47, belt 48 and rotating shaft 2 49 to rotate, so as to realize the driving operation of the transmission component 4 by means of the vertical plate 2 33.

[0026] In some embodiments, more specifically, the guide rod 44 can be inserted into the shaft sleeve 46, and in the initial state, the balls on the guide rod 44 are located at the highest point of the spiral groove.

[0027] Next, a more specific structure and construction of the feeding component 5 will be given for further explanation. The driving section of the feeding component 5 includes: a chassis 51, which is detachably mounted on the mounting frame 41; and a displacement plate 52, which is detachably mounted on the chassis 51. The displacement plate 52 has multiple sets of slides, and a displacement plate 53 is slidably arranged in each set of slides. A wedge block 54 is provided at one end of the displacement plate 53, and an inclined surface is provided on the wedge block 54. A short [unclear] is provided at the other end of each set of displacement plates 53. The feeding component 5 includes: a rod 55; a drive wheel 56 detachably connected to the rotating shaft 49; multiple sets of grooves within the drive wheel 56, each groove being passable by the short rod 55; the movement trajectory of the short rod 55 being in the same direction as the grooves; and a feeding section comprising: a top plate 57 detachably mounted on the base plate 51; an inner plate 571 detachably disposed within the top plate 57, the inner plate 571 having an annular cavity; and an inner ring 572 disposed within the top plate 57, the inner ring 572 and the inner plate 571 forming a first ring. A first clamping cavity includes a feeding ring 573, which has a first conical surface. The first conical surface and the inner plate 571 form a first feeding cavity. An inner ring 574 is disposed within the top plate 57 and is adjacent to the inner ring 572. An outer ring 575 is disposed within the top plate 57, and the outer ring 575 and the inner ring 574 form a second clamping cavity. A feeding ring 576 is disposed within the second clamping cavity and has a second conical surface. The second conical surface and the inner ring 571 form a first feeding cavity. A second feeding chamber is formed between 4; multiple sets of pushers 58 are detachably arranged at the bottom of the top plate 57, and a portion of the pushers 58 correspond to the area where the first feeding ring 573 is located, while another portion of the pushers 58 correspond to the area where the second inner ring 574 is located; a screen plate 577 is arranged in the ring cavity; a feed cylinder 59 is arranged in the top plate 57, and a connecting shaft 591 is rotatably arranged in the feed cylinder 59, and the connecting shaft 591 is connected to the drive wheel 56, and a auger blade 592 is provided on the connecting shaft 591; Next, the overall operating principle and effect of the feeding component 5 will be further explained. When the rotating shaft 49 rotates, it can drive the drive wheel 56 to rotate. The drive wheel 56 can drive the short rod 55 to move along the layout direction of the groove through the groove, thereby driving multiple sets of displacement plates 53 and wedge blocks 54 to spread around the displacement disk 52. At the same time, it can squeeze and move the contact wheel 584 and the insert rod 583. After the insert rod 583 located below the feeding ring 573 moves upward, it can push the space between the first conical surface of the feeding ring 573 and the inner disk 571. The silicon carbide powder in the first feeding chamber is injected into the annular cavity of the inner disk 571. On the one hand, this allows for timely replenishment of the powder while the grinding disk 35 moves downward to apply pressure to the silicon carbide powder, enhancing the grinding effect. After the newly added material enters the annular cavity of the inner disk 571, the feeding process and feeding time are saved. Furthermore, the new material is mixed with the old material in the inner disk 571, allowing for thorough grinding by the grinding disk 35, further enhancing the grinding efficiency of the grinding disk 35. Simultaneously, as the grinding disk 35 continues to move downward, it can also compress the wedge... The block 54 abuts against the outer contact wheel 584, causing the outer contact wheel 584 and the insert rod 583 to move upward. This pushes the silicon carbide powder in the second feeding cavity formed between the second conical surface of the feeding ring 576 and the inner ring 574 into the first feeding cavity. The powder then slides down the first conical surface into the annular cavity of the inner disc 571. As the grinding disc 35 moves downward, the pressure between it and the silicon carbide powder increases, allowing for secondary feeding and continued grinding based on the first grinding by the grinding disc 35. This further promotes the grinding disc 35's processing of the silicon carbide powder. The mixed grinding operation of the old material further enhances the grinding effect of the grinding disc 35 on the silicon carbide powder. In addition, during the two grinding processes of the silicon carbide powder by the grinding disc 35, the drive wheel 56 can synchronously drive the connecting shaft 591 in the feed cylinder 59 to rotate. This allows the grinding silicon carbide powder in the feed cylinder 59 to be transported to the annular cavity of the inner disc 571 through the auger blade 592 to continue to participate in the grinding process of the grinding disc 35, thereby performing a secondary grinding and refining operation on the silicon carbide powder and enhancing the grinding and preparation efficiency and finished product effect of the silicon carbide powder.

[0028] In some embodiments, more specifically, the inner disk 571 also has a conical cavity, through which silicon carbide powder flows into the inner disk 571 and then flows to the bottom of the inner disk 571. A trough is also provided at the bottom of the feed cylinder 59, and the trough and the conical cavity are interconnected.

[0029] Next, a more specific structure and construction of the pusher 58 will be given for further explanation. The pusher 58 includes: a bottom frame 581, which is detachably arranged at the bottom of the top plate 57, and a liner 582 inside the bottom frame 581; a rod 583, which can pass through the bottom frame 581 and the liner 582 in sequence, and an abutting wheel 584 at one end of the rod 583, and a spring is sleeved on the rod 583. Next, the working principle of the pusher 58 will be further explained. When the wedge block 54 moves upward, it can squeeze the contact wheel 584 and the insert rod 583 to move upward and squeeze the spring to be compressed, thereby driving the feeding ring 1 573 and feeding ring 2 576 to move upward, and the insert rod 583 can be inserted into the top plate 57.

[0030] Another technical problem to be solved by the present invention is a method for preparing silicon carbide powder preparation equipment. S1. Feeding silicon carbide powder: Injecting silicon carbide powder into the feeding component 5; S2. Adjustment of the overall position of the grinding component 3: By opening the adjustment component 2, the overall position of the grinding component 3 along the front and back can be adjusted; S3. Grinding and preparation of silicon carbide powder: By turning on the grinding component 3, the silicon carbide powder in the feeding component 5 can be ground and prepared. S4. Triggering operation of the conductive component 4: After the grinding component 3 grinds and prepares the silicon carbide powder in the feeding component 5, the grinding component 3 is driven to move downward. On the one hand, this can enhance the grinding effect of the silicon carbide powder in the feeding component 5, and on the other hand, it can trigger the operation of the conductive component 4. S5. Feeding operation of the inner annular cavity of the feeding component 5: When the transmission component 4 is triggered by the grinding component 3, it can force the driving section to tend to extend in all directions. After the driving section tends to extend in all directions, it can progressively squeeze the feeding section to force the silicon carbide powder in the feeding section into the annular cavity of the feeding section.

[0031] In summary, through the arrangement of the feeding component 5, on the one hand, it can apply pressure to the silicon carbide powder as the grinding disc 35 moves downward, enhancing the grinding effect of the silicon carbide powder, and on the other hand, it can perform timely replenishment operations. After the newly added material enters the annular cavity in the inner disc 571, it can save the feeding process and feeding time, and can also mix the new material with the old material in the inner disc 571, and fully grind it through the grinding disc 35, further enhancing the grinding efficiency of the grinding disc 35. At the same time, as the grinding disc 35 continues to move downward, it can also squeeze the wedge block 54 to abut against the outer contact wheel 584, so that the outer contact wheel 584 and the insert rod 583 move upward, which can push the silicon carbide powder in the second feeding cavity formed between the second conical surface of the feeding ring 576 and the inner ring 574 into the first feeding cavity, and use the first conical surface to slide down Within the annular cavity of the inner disc 571, the pressure between the grinding disc 35 and the silicon carbide powder increases as the grinding disc 35 moves downward, allowing for secondary grinding based on the initial grinding by the grinding disc 35. This further promotes the mixing and grinding of the new and old silicon carbide powder by the grinding disc 35, enhancing the grinding effect of the silicon carbide powder. Furthermore, during the two grinding processes of the silicon carbide powder by the grinding disc 35, the drive wheel 56 simultaneously rotates, driving the connecting shaft 591 within the feed cylinder 59 to rotate. This allows the auger blade 592 to transport the ground silicon carbide powder from the feed cylinder 59 to the annular cavity of the inner disc 571 for further grinding by the grinding disc 35, thus refining the silicon carbide powder and enhancing the grinding efficiency and finished product quality.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
