Description

Technical Field

[0001] This utility model belongs to the field of diamond synthesis technology, specifically relating to a positioning growth device for large-particle diamond synthesis. Background Technology

[0002] Large diamonds are formed from high-purity graphite under high temperature and pressure. Diamonds are the hardest known natural substance in the world, and their production is rare. They are usually colorless crystals with high refractive properties, refracting a variety of colors of luster. Diamonds are not only used in jewelry but also as high-grade cutting and grinding materials in industry. However, in the production of lab-grown diamonds, the distribution and position of the seed crystals on the matrix determine their temperature range, their ability to compete for carbon sources, and their growth space. Lab-grown diamonds near the heating graphite and in areas with sufficient carbon source supply grow at a slower rate. The growth rate is relatively fast. When the carbon source distribution around the seed crystal is uneven, it can lead to misalignment of the seed crystal and aggregation of the seed crystal. As the number of carbon atoms deposited on the seed crystal gradually increases, the synthesized large diamond particles will also aggregate, making it more difficult to control their clarity and shape. It is difficult to grow complete, regular, large, high-grade diamond particles, and the quality of synthesized large diamond particles is also poor, which seriously affects the quality and yield of the product. Therefore, it is very necessary to provide a positioning growth device for the synthesis of large diamond particles that has a reasonable structure, ensures uniform carbon source, is conducive to the growth of complete crystal forms, and improves the quality of diamond crystals.

Multiple positioning holes corresponding one-to-one with the inlet holes are evenly distributed on the upper surface of the positioning plate.

[0006] The outer periphery of the inlet hole is evenly provided with multiple positioning grooves, and the bottom surface of the pressure equalizing plate is provided with positioning strips that correspond one-to-one with the positioning grooves relative to the outer periphery of the pressure rod.

[0007] The fixed chassis includes an installation frame connected to the bottom of the support frame. Multiple double-layer support skeletons are evenly arranged on the outer periphery of the installation frame, and a multi-hole fixing plate fixed to the base is provided at the outer end of the support skeleton.

[0008] The lifting mechanism includes a base plate, with mounting plates on both sides of the base plate. Both the base plate and the mounting plates are connected to the upper part of the support frame. A bidirectional output gearbox is located below the base plate. A DC brushless motor is connected to the rear of the bidirectional output gearbox. Output bearing discs are located on both sides of the bidirectional output gearbox. A synchronous output shaft is axially connected to the output bearing discs. The synchronous output shaft is connected to the mounting plate through a transverse bearing seat. Drive bevel gears are located at both ends of the synchronous output shaft.

[0009] Each mounting plate has a vertical plate below it, and longitudinal bearing seats are provided on the upper and lower sides of the inner side of the vertical plate. A transmission screw is provided inside the longitudinal bearing seat. The transmission screw is connected to a nut seat. A reversing bevel gear that meshes with the drive bevel gear is provided at the upper end of the transmission screw.

[0010] The bidirectional output gearbox has a worm gear that is powered by a brushless DC motor. The upper end of the worm gear is engaged with a worm wheel, which is connected to the synchronous output shaft through a coupling sleeve.

[0011] The stroke changing mechanism includes multiple bushings located outside the synchronous output shaft. The upper end of each bushing is connected to the support frame via a connecting rod, and the lower end is connected to the pressing mechanism via a stroke adjusting telescopic rod.

[0012] The pressing mechanism includes a top plate, a cylinder is provided on one side below the top plate, and several sets of first T-shaped support plates are spaced apart on the bottom surface of the top plate. Each set of first T-shaped support plates is connected to an L-shaped support plate between each pair of first T-shaped support plates. Guide rollers are provided below the front of each L-shaped support plate. A movable rack is provided inside each set of first T-shaped support plates. The movable rack is located below the guide roller and is tactilely connected to the guide roller. The movable racks are connected to each other through quick couplings, and a first spur gear meshes below the movable rack.

[0013] The bottom surface of the top plate is provided with several second T-shaped support plates at intervals. Each second T-shaped support plate is provided with a second spur gear connected to the corresponding first spur gear shaft. Each second spur gear is provided with an arc-shaped open sleeve on one side. Each arc-shaped open sleeve is provided with a stroke gear that meshes with the corresponding second spur gear. The stroke gear is slidably connected to the arc-shaped open sleeve. Each stroke gear is fixedly connected to a synchronous pressure block at the lower end.

[0014] The beneficial effects of this utility model are as follows: This utility model is a positioning growth device for the synthesis of large-particle diamonds.

The lifting mechanism and nut seat work together to make the insertion plate move down smoothly and combine with the bottom mold. At this time, the inlet hole and the positioning hole are aligned, ensuring the accuracy of the positioning hole during the hole setting process. Then, the pressing mechanism is activated, and the material to be pressed into the positioning hole is accurately weighed and then introduced through the inlet hole to achieve uniform material distribution. Since multiple positioning grooves are evenly arranged on the outer periphery of the inlet hole, and the outer periphery of the pressing rod is provided with positioning strips that correspond one-to-one with the positioning grooves, the docking and cooperation between the pressing rod and the inlet hole can be more accurate, ensuring that the pressing rod can be accurately and quickly inserted into the inlet. Within the hole, the pressure rod and the guide hole are reliably and quickly positioned, allowing the pressure rod to pass through the guide hole and press against the substrate to accurately position the seed crystal. The selected seed crystal is then placed at the pressed positioning point as required, ensuring the uniformity of space for diamond crystal growth and carbon source supply. The pressing mechanism uses multiple synchronous pressing blocks to simultaneously press down, ensuring the downward pressure is evenly distributed on the equalizing plate. This results in the equalizing plate exerting the same and even downward pressure on each pressure rod, making the downward force of the equalizing plate on the pressure rod more stable. This allows for seed planting based on the positioning point, resulting in a more uniform distribution of carbon source around the seed crystal, leading to better growth conditions and promoting the growth of a complete crystal form. This reduces the occurrence of abnormal growth in lab-grown diamond crystals under conditions of unreasonable resource allocation, thus ensuring improved quality. This invention has the advantages of reasonable structure, ensuring uniform carbon source, promoting the growth of a complete crystal form, and improving diamond crystal quality.

[0025] like Figure 1-8As shown, a positioning growth device for synthesizing large diamond particles includes a base 1, a support frame 2 above the base 1, the support frame 2 being fixedly connected to the base 1 via a fixed base plate 3, and a lifting mechanism 8 installed above the support frame 2. A bottom mold 4 is fixedly installed at the upper middle part of the base 1, a positioning plate 5 is fixedly installed at the bottom inside the bottom mold 4, and an insertion plate 6 is slidably connected inside the bottom mold 4. Both ends of the insertion plate 6 are provided with nut seats 7 connected to the lifting mechanism 8, and the insertion plate 6 can move up and down inside the bottom mold 4 by the cooperation of the lifting mechanism 8 and the nut seats 7. A pressing mechanism 12 is provided inside the lifting mechanism 8, and a pressure equalizing plate 13 is provided at the lower end of the pressing mechanism 12. Multiple pressure rods 14 are fixedly installed at equal intervals at the lower end of the pressure equalizing plate 13. Multiple guide holes 15 adapted to the pressure rods 14 are provided through the insertion plate 6. A stroke changing mechanism is installed above the pressing mechanism 12 to change the stroke of the pressing mechanism 12.

[0026] Multiple docking rods 19 are evenly distributed below the bottom mold 4. Multiple positioning sleeves 18 are provided inside the base 1, which correspond one-to-one with the docking rods 19 and are fixedly connected by plugging. Multiple positioning holes corresponding one-to-one with the inlet holes 15 are evenly distributed on the upper surface of the positioning plate 5.

[0027] The outer periphery of the inlet hole 15 is provided with a plurality of positioning grooves 16, and the bottom surface of the pressure plate 13 is provided with positioning strips 17 that correspond one-to-one with the positioning grooves 16 relative to the outer periphery of the pressure rod 14.

[0028] The fixed chassis 3 includes an installation frame 31 connected to the bottom of the support frame 2. Multiple double-layer support skeletons 32 are evenly arranged on the outer periphery of the installation frame 31. A multi-hole fixing plate 33 fixed to the base 1 is provided at the outer end of the support skeleton 32.

[0029] The lifting mechanism 8 includes a base plate 81, with mounting plates 82 on both sides of the base plate 81. Both the base plate 81 and the mounting plates 82 are connected to the upper part of the support frame 2. A bidirectional output gearbox 83 is provided under the base plate 81. A DC brushless motor 84 is powered to the rear of the bidirectional output gearbox 83. Output bearing discs 85 are provided on both sides of the bidirectional output gearbox 83. A synchronous output shaft 86 is axially connected to the output bearing discs 85. The synchronous output shaft 86 is connected to the mounting plate 82 through a transverse bearing seat 87. Both ends of the synchronous output shaft 86 are provided with drive bevel gears 88.

[0030] A vertical plate 89 is provided below each of the mounting plates 82. A longitudinal bearing seat 801 is provided on both the upper and lower sides of the inner side of the vertical plate 89. A transmission screw 802 is provided inside the longitudinal bearing seat 801. The transmission screw 802 is connected to the nut seat 7. A reversing bevel gear 803 that meshes with the drive bevel gear 88 is provided at the upper end of the transmission screw 802.

[0031] The bidirectional output gearbox 83 is internally equipped with a worm gear 301 that is powered by a DC brushless motor 84. The upper end of the worm gear 301 is engaged with a worm wheel 302, which is connected to the synchronous output shaft 86 through a coupling sleeve 303.

[0032] In this embodiment, the working principle of the lifting mechanism is as follows: the brushless DC motor is started, and the brushless DC motor realizes the rotation of the synchronous output shaft through the cooperation of the worm, worm wheel, and coupling sleeve. The synchronous output shaft uses the drive bevel gear at the end to drive the reversing bevel gear to rotate, and the reversing bevel gear drives the transmission screw to rotate, thereby realizing the synchronous rotation of the two transmission screws. The transmission screw drives the insertion plate to move down through the cooperation with the nut seat and combines with the bottom mold.

[0033] This invention relates to a positioning growth device for the synthesis of large-particle diamonds. In use, the support frame 2 is fixedly connected to the base 1 via a fixed chassis 3, ensuring the device's safety, reliability, and stability. The bottom mold 4 is connected to the positioning sleeve 18 inside the base 1 via a connecting rod 19, enabling quick installation and replacement of the bottom mold 4, making it convenient and fast to use. The lifting mechanism 8 and the nut seat 7 work together to allow the insertion plate 6 to move smoothly downwards and combine with the bottom mold 4. At this point, the inlet hole 15 aligns with the positioning hole, ensuring the accuracy of the positioning hole during the hole-setting process. Then, the pressing mechanism 12 is activated, accurately weighing the material to be pressed into the positioning hole through the inlet hole 15 and spreading it evenly to achieve uniform material distribution. Since the inlet hole 15 has multiple positioning grooves 16 evenly arranged on its outer periphery, and the pressing rod 14 has positioning strips 17 that correspond one-to-one with the positioning grooves 16 on its outer periphery, the docking and cooperation between the pressing rod 14 and the inlet hole 15 is more accurate, ensuring that the pressing rod 14 can be accurately and quickly inserted into the inlet hole. Within the hole 15, the pressure rod 14 and the inlet hole 15 are reliably and quickly positioned, allowing the pressure rod 14 to pass through the inlet hole 15 and press against the substrate to accurately position the seed crystal. The selected seed crystal is then placed at the pressed positioning point as required, ensuring the uniformity of space for diamond crystal growth and carbon source supply. The pressing mechanism 12 simultaneously presses down through multiple synchronous pressing blocks 204, ensuring the downward pressure is evenly distributed on the equalizing plate 13. This results in the equalizing plate 13 exerting the same and average downward pressure on each pressure rod 14, making the downward force of the equalizing plate 13 on the pressure rod 14 more stable. This allows for seed planting based on the positioning point, resulting in a more uniform distribution of carbon source around the seed crystal, leading to better growth conditions and promoting the growth of a complete crystal form. This reduces the occurrence of abnormal growth of diamond crystals under conditions of unreasonable resource allocation, thus ensuring the improvement of diamond crystal quality. This invention has the advantages of reasonable structure, ensuring uniform carbon source, promoting the growth of a complete crystal form, and improving diamond crystal quality. Example

[0034] like Figure 1-8 As shown, a positioning growth device for synthesizing large diamond particles includes a base 1, a support frame 2 above the base 1, the support frame 2 being fixedly connected to the base 1 via a fixed base plate 3, and a lifting mechanism 8 installed above the support frame 2. A bottom mold 4 is fixedly installed at the upper middle part of the base 1, a positioning plate 5 is fixedly installed at the bottom inside the bottom mold 4, and an insertion plate 6 is slidably connected inside the bottom mold 4. Both ends of the insertion plate 6 are provided with nut seats 7 connected to the lifting mechanism 8, and the insertion plate 6 can move up and down inside the bottom mold 4 by the cooperation of the lifting mechanism 8 and the nut seats 7. A pressing mechanism 12 is provided inside the lifting mechanism 8, and a pressure equalizing plate 13 is provided at the lower end of the pressing mechanism 12. Multiple pressure rods 14 are fixedly installed at equal intervals at the lower end of the pressure equalizing plate 13. Multiple guide holes 15 adapted to the pressure rods 14 are provided through the insertion plate 6. A stroke changing mechanism is installed above the pressing mechanism 12 to change the stroke of the pressing mechanism 12.

[0035] Multiple docking rods 19 are evenly distributed below the bottom mold 4. Multiple positioning sleeves 18 are provided inside the base 1, which correspond one-to-one with the docking rods 19 and are fixedly connected by plugging. Multiple positioning holes corresponding one-to-one with the inlet holes 15 are evenly distributed on the upper surface of the positioning plate 5.

[0036] The outer periphery of the inlet hole 15 is provided with a plurality of positioning grooves 16, and the bottom surface of the pressure plate 13 is provided with positioning strips 17 that correspond one-to-one with the positioning grooves 16 relative to the outer periphery of the pressure rod 14.

[0037] The fixed chassis 3 includes an installation frame 31 connected to the bottom of the support frame 2. Multiple double-layer support skeletons 32 are evenly arranged on the outer periphery of the installation frame 31. A multi-hole fixing plate 33 fixed to the base 1 is provided at the outer end of the support skeleton 32.

[0038] The stroke changing mechanism includes multiple bushings 9 located outside the synchronous output shaft 86. The upper end of each bushing 9 is connected to the support frame 2 via a connecting rod 10, and the lower end is connected to the pressing mechanism 12 via a stroke adjusting telescopic rod 11.

[0039] In this embodiment, the working principle of the stroke changing mechanism is as follows: the bushing is sleeved and installed outside the synchronous output shaft and rotates relative to the synchronous output shaft. Therefore, the bushing does not interfere with the movement of the synchronous output shaft. The lower end of the bushing is connected to the pressing mechanism through the stroke adjusting telescopic rod. Therefore, the relative height position of the pressing mechanism can be adjusted by changing the length of the stroke adjusting telescopic rod, thereby changing the pressing stroke range of the pressing mechanism. This allows for adaptive adjustments based on actual needs (such as the length of the pressure rod, the height of the insert plate, and the sliding stroke of the insert plate inside the bottom mold), greatly improving the practicality, applicability, and versatility of the device.

[0040] The pressing mechanism 12 includes a top plate 21. A cylinder 22 is provided on one side below the top plate 21. Several sets of first T-shaped support plates 23 are spaced apart on the bottom surface of the top plate 21. An L-shaped support plate 24 is provided between each pair of the first T-shaped support plates 23. A guide roller 25 is provided below the front of each L-shaped support plate 24. A movable rack 26 is provided inside each set of first T-shaped support plates 23. The movable rack 26 is located below the guide roller 25 and is tactilely connected to the guide roller 25. The movable racks 26 are connected to each other through a quick connector 27. A first spur gear 28 meshes below the movable rack 26.

[0041] The bottom surface of the top plate 21 is provided with a plurality of second T-shaped support plates 29 at intervals. Each of the second T-shaped support plates 29 is provided with a second spur gear 201 connected to the shaft of the corresponding first spur gear 28. Each of the second spur gears 201 is provided with an arc-shaped open sleeve 202 on one side. Each arc-shaped open sleeve 202 is provided with a stroke rack 203 that meshes with the corresponding second spur gear 201. The stroke rack 203 is slidably connected to the arc-shaped open sleeve 202. Each stroke rack 203 is fixedly connected to a synchronous pressure block 204 at its lower end.

[0042] In this embodiment, the working principle of the pressing mechanism is as follows: the cylinder is connected to the free end of the moving gear near the cylinder through a floating joint. When the cylinder is activated, it drives the moving gear to move laterally. Since the moving gears are connected through quick joints, the cylinder can simultaneously drive multiple moving gears to move laterally through the floating joints. The upper surface of the moving gear is in rolling contact with the guide roller, and the lower surface meshes with the first spur gear. The guide roller, on the one hand, cooperates with the first spur gear to guide and limit the moving gear, enabling it to move smoothly and reliably; on the other hand, rolling friction is used between the guide roller and the moving gear to reduce frictional resistance. This reduces the cylinder load and ensures that the cylinder can reliably drive multiple moving racks to work normally. Therefore, during the lateral movement of the moving rack, the moving rack will synchronously drive the first spur gear to rotate. Since the first spur gear is connected to the shaft of the second spur gear, the second spur gear can rotate synchronously. Since the second spur gear meshes with the stroke rack, the stroke rack can be driven to move synchronously through the second spur gear, thereby realizing that multiple synchronous pressure blocks move down at the same time, so that the downward pressure is evenly distributed on the pressure equalizing plate, thus making the downward pushing force of the pressure equalizing plate on each pressure rod the same and average, making the downward pushing force of the pressure equalizing plate on the pressure rod more stable.

[0043] This invention relates to a positioning growth device for the synthesis of large-particle diamonds. In use, the support frame 2 is fixedly connected to the base 1 via a fixed chassis 3, ensuring the device's safety, reliability, and stability. The bottom mold 4 is connected to the positioning sleeve 18 inside the base 1 via a connecting rod 19, enabling quick installation and replacement of the bottom mold 4, making it convenient and fast to use. The lifting mechanism 8 and the nut seat 7 work together to allow the insertion plate 6 to move smoothly downwards and combine with the bottom mold 4. At this point, the inlet hole 15 aligns with the positioning hole, ensuring the accuracy of the positioning hole during the hole-setting process. Then, the pressing mechanism 12 is activated, accurately weighing the material to be pressed into the positioning hole through the inlet hole 15 and spreading it evenly to achieve uniform material distribution. Since the inlet hole 15 has multiple positioning grooves 16 evenly arranged on its outer periphery, and the pressing rod 14 has positioning strips 17 that correspond one-to-one with the positioning grooves 16 on its outer periphery, the docking and cooperation between the pressing rod 14 and the inlet hole 15 is more accurate, ensuring that the pressing rod 14 can be accurately and quickly inserted into the inlet hole. Within the hole 15, the pressure rod 14 and the inlet hole 15 are reliably and quickly positioned, allowing the pressure rod 14 to pass through the inlet hole 15 and press against the substrate to accurately position the seed crystal. The selected seed crystal is then placed at the pressed positioning point as required, ensuring the uniformity of space for diamond crystal growth and carbon source supply. The pressing mechanism 12 simultaneously presses down through multiple synchronous pressing blocks 204, ensuring the downward pressure is evenly distributed on the equalizing plate 13. This results in the equalizing plate 13 exerting the same and average downward pressure on each pressure rod 14, making the downward force of the equalizing plate 13 on the pressure rod 14 more stable. This allows for seed planting based on the positioning point, resulting in a more uniform distribution of carbon source around the seed crystal, leading to better growth conditions and promoting the growth of a complete crystal form. This reduces the occurrence of abnormal growth of diamond crystals under conditions of unreasonable resource allocation, thus ensuring the improvement of diamond crystal quality. This invention has the advantages of reasonable structure, ensuring uniform carbon source, promoting the growth of a complete crystal form, and improving diamond crystal quality.
