Description

Technical Field

[0001] This utility model relates to the field of crystal production equipment technology, and in particular to a crucible clamping and rotating device. Background Technology

[0002] In the field of crystal materials, the down-growing method is one of the important methods for preparing large-size, high-quality single crystals. In this process, crucible wrapping is a preliminary step in down-growing crystal growth. The purpose of crucible wrapping is to use a flexible platinum crucible to completely encapsulate and seal the seed crystal and the crystal material, thereby creating a pure and vacuum environment for crystal growth.

[0003] During the crucible-wrapping process, multiple flipping and shaping operations are required to ensure a tight fit between the crucible bottom and the seed crystal to optimize heat conduction and to properly encapsulate the crystal inside the crucible. However, this process currently relies mainly on manual labor. The smooth platinum crucible is prone to damage to the valuable crystal during manual rotation and flipping. Furthermore, the heavy weight of the crystal makes the flipping operation labor-intensive and requires multiple people to work together, resulting in low production safety and efficiency.

[0004] Therefore, there is an urgent need for a crucible clamping and rotating device that can stably clamp and rotate the crucible in multiple directions. Utility Model Content

[0010] Optionally, the tilting adjustment mechanism also includes a drive handle, a worm gear mechanism, and a second locking element; The worm gear mechanism is connected to the drive handle and the tilting adjustment ring respectively.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0024] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0025] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0026] In the crucible wrapping process, multiple flipping and shaping operations are usually required to ensure that the bottom of the crucible and the seed crystal, which serves as the starting point for growth, are in close contact from all angles to establish good heat conduction conditions. At the same time, the loose crystal material is properly wrapped inside the crucible. This process step has a significant impact on the quality of subsequent single crystal growth.

[0027] In related technologies, this process mainly relies on manual operation. During the crucible wrapping process, large-sized crystals and crucibles need to be flipped multiple times. Due to the smooth surface of the platinum crucible, it is easy for manual handling to cause slippage, resulting in the crystals inside breaking due to impacts. This leads to poor operational safety and easy damage to the crystals. Furthermore, since crystal specifications vary in the research and development or production stages, and large-sized crystals can weigh 20 to 50 kilograms, it is difficult to safely and repeatedly rotate and flip such heavy objects by hand, thus hindering the research and development progress of large-sized and new-specification crystals. In addition, due to the weight of the crystals, a single crucible wrapping operation usually requires 2 to 3 people to work together, resulting in low overall production efficiency.

[0028] This utility model provides a crucible clamping and rotating device that can solve some or all of the technical problems in related technologies.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a crucible clamping and rotating device provided in an embodiment of the present invention. Figure 2 yes Figure 1 The diagram shown is an exploded view of a crucible clamping and rotating device. Figure 3 This is a schematic diagram of the structure of a crucible clamping and rotating device and a crucible 20 provided in an embodiment of the present invention. The crucible clamping and rotating device may include: a load-bearing base 11, a flipping adjustment mechanism 12, a rotating adjustment ring 13, and a crucible fixing mechanism 14.

[0030] The tilting adjustment mechanism 12 is rotatably mounted on the load-bearing base 11; the rotating adjustment ring 13 is rotatably mounted on the tilting adjustment mechanism 12; the crucible fixing mechanism 14 is detachably mounted on the rotating adjustment ring 13 and is used to clamp the crucible 20, which can be used to load seed crystals and raw materials. When the crucible 20 is mounted on the crucible fixing mechanism 14, the crucible 20 can be inserted through the rotating adjustment ring 13, so that both ends of the crucible 20 can be exposed, which facilitates the operator to wrap the top, bottom and sides of the crucible 20.

[0031] The rotating adjustment ring 13 is configured to drive the crucible fixing mechanism 14 and the crucible 20 to rotate around a first axis. The flipping adjustment mechanism 12 is configured to drive the rotating adjustment ring 13, the crucible fixing mechanism 14, and the crucible 20 to rotate around a second axis, which intersects the first axis. For example, the first axis can be parallel to the axis of the rotating adjustment ring 13, meaning the rotating adjustment ring 13 can drive the crucible fixing mechanism 14 and the crucible 20 held by the crucible fixing mechanism 14 to rotate around the axis of the rotating adjustment ring 13. The second axis can be perpendicular to the first axis and parallel to the radial direction of the rotating adjustment ring 13. Thus, the flipping adjustment mechanism 12 can drive the rotating adjustment ring 13, the crucible fixing mechanism 14, and the crucible 20 held by the crucible fixing mechanism 14 to rotate radially around the rotating adjustment ring 13.

[0032] Please continue to refer to this. Figure 4 , Figure 4 This is a partial structural schematic diagram of a crucible 20 and a crucible clamping and rotating device provided in an embodiment of the present invention. Figure 3 The crucible 20 shown is in a horizontal position. Figure 4 The crucible 20 shown is in a vertical position. In one exemplary embodiment, the rotating adjustment ring 13 can drive the crucible 20 to rotate 360° around a first axis, and the flipping adjustment mechanism 12 can drive the crucible 20 to rotate 360° around a second axis. For example, the flipping adjustment mechanism 12 can drive the crucible 20 to flip between a vertical and a horizontal position, and the rotating adjustment ring 13 can drive the crucible 20 to rotate after it is in a horizontal position, so that different sides of the crucible 20 face upwards.

[0033] In this embodiment of the invention, the combination of the flipping adjustment mechanism 12 and the rotating adjustment ring 13 enables the crucible 20 mounted on the crucible clamping and rotating device to have a 360-degree degree of freedom to rotate around two intersecting axes. During the process of wrapping the crucible, the operator can easily flip and switch the crucible 20 between the vertical and horizontal states and enable the crucible 20 to rotate around its own axis.

[0034] Thus, the mechanical clamping and rotation of the crucible clamping and rotating device avoids the direct manual handling of the smooth platinum crucible 20, reducing the risk of crystal breakage due to operator slippage and improving operator safety. Furthermore, since the crucible 20 can be fixed on the crucible fixing mechanism 14, even if the crucible 20 and the seed crystals and material inside it are heavy, one operator can cover multiple sides of the crucible 20. For example, the crucible 20 can be square. After the crucible 20 is adjusted to a horizontal position, rotating the adjusting ring 13 can easily rotate the four sides of the crucible 20 sequentially to the upward position, facilitating precise covering, shaping, and inspection of the seed crystals without the need for multiple people to laboriously flip it. The crucible 20 in this embodiment can also be round or of other shapes; there is no limitation on this.

[0035] Furthermore, the load-bearing base 11 provides support for the crucible 20, ensuring that the crucible clamping and rotating device does not wobble during operations such as hammering and shaping of the crucible 20. This provides a stable working platform for operations that ensure the bottom of the crucible 20 is in close contact with the seed crystal. Moreover, since the crucible fixing mechanism 14 is detachable, it can be adapted to different sizes and specifications of crucibles 20 by replacing the fixing mechanism 14, thus improving the applicability of the crucible clamping and rotating device.

[0036] In summary, this utility model provides a crucible clamping and rotating device including a load-bearing base 11, a flipping adjustment mechanism 12, a rotating adjustment ring 13, and a crucible fixing mechanism 14. The rotating adjustment ring 13 can drive the crucible fixing mechanism 14 and the crucible 20 to rotate around a first axis, and the flipping adjustment mechanism 12 can drive the rotating adjustment ring 13, the crucible fixing mechanism 14, and the crucible 20 to rotate around a second axis. Through the synergistic effect of the flipping and rotating mechanisms, this device enables the crucible 20 to achieve precise positioning with multiple degrees of freedom, providing a better working state for the crucible 20: the vertical state facilitates loading and unloading; the horizontal state allows the crucible 20 to be laid down, facilitating subsequent four-sided covering operations. Furthermore, replacing manual operation with mechanical clamping reduces the risk of crystal impact and personal injury, and allows a single person to complete the all-round crucible covering operation; at the same time, the stable base and adaptable clamping mechanism can improve the stability and versatility of the device.

[0037] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 , Figure 5 yes Figure 3 The diagram shows the structure of the crucible clamping and rotating device and the crucible 20 from another orientation. Figure 6This is a schematic diagram of the structure of a crucible fixing mechanism 14 provided in an embodiment of the present invention. In an optional embodiment, the crucible fixing mechanism 14 may include a crucible support base 141 detachably mounted on a rotating adjusting ring 13 and a plurality of crucible clamping members 142. The plurality of crucible clamping members 142 are arranged around the center of the rotating adjusting ring 13 for clamping the crucible 20 from the side, and the crucible support base 141 is used to support the end of the crucible 20.

[0038] The rotating adjustment ring 13 has a front and a back side that are arranged opposite to each other. The crucible clamp 142 can be installed on the front side of the rotating adjustment ring 13, and part of the structure of the crucible clamp 142 can be inserted into the rotating adjustment ring 13 so that the contact area between the crucible clamp 142 and the side of the crucible 20 is large.

[0039] The crucible support 141 can be installed on the back of the rotating adjustment ring 13, and the crucible support 141 can be located at the end of the crucible 20 to support the bottom of the crucible 20. The crucible support 141 can also be used to support the seed crystals located in the crucible 20 to prevent the seed crystals from falling out of the crucible 20 before the crucible is wrapped.

[0040] For crucibles 20 of different specifications, the crucible clamp 142 and the crucible support 141 can be disassembled and replaced to adapt to different specifications of crucibles 20. Furthermore, the crucible support 141 can be disassembled or installed in different process steps. For example, when the crucible 20 is in a vertical position and no crucible covering operation is performed, the top of the crucible 20 faces upwards, and the bottom of the crucible 20 is in contact with the crucible support 141. The seed crystals in the crucible 20 can also contact the crucible support 141. At this time, the crucible support 141 is in the installed state. After the crucible covering operation is performed on the top of the crucible 20, the crucible 20 can be rotated to a horizontal position using the flipping adjustment mechanism 12. Then, the crucible support can be removed to facilitate the operator's crucible covering operation on the bottom of the crucible 20.

[0041] Please refer to Figure 3 , Figure 4 and Figure 7 , Figure 7 yes Figure 1The schematic diagram of another orientation of the crucible clamping and rotating device shows that, in an optional embodiment, the crucible clamping member 142 may include a crucible clamping plate 1421 and a first locking member 1422. The crucible clamping member 142 is slidably connected to the rotating adjusting ring 13 and can move radially along the rotating adjusting ring 13. The first locking member 1422 is movably connected to the rotating adjusting ring 13 and can press the crucible clamping member 142 against the outer wall of the crucible 20. Through the cooperative action of the crucible clamping plate 1421 and the first locking member 1422, the crucible clamping member 142 can form a clamping mechanism capable of radial adjustment and locking. The sliding connection between the crucible clamp 1421 and the rotating adjustment ring 13 allows the crucible clamp 1421 to move radially, thereby adapting to crucibles 20 of different sizes and specifications. The first locking member 1422 located on the outside of the crucible clamp 1421 drives the crucible clamp 1421 to complete fine adjustment and apply a constant clamping force through the tightening action, thereby firmly fixing the crucible 20.

[0042] Thus, the radially sliding crucible holder 142 can be adapted to crucibles 20 of various sizes; the reliable locking mechanism can ensure that the crucible 20 does not loosen during flipping and tapping, reducing operational risks.

[0043] For example, the rotating adjusting ring 13 may have a first protrusion t1, which may extend to the front of the rotating adjusting ring 13. The first protrusion t1 has an adjusting threaded hole. The first locking member 1422 may include a first T-shaped locking screw with a quincunx-shaped handle. The first T-shaped locking screw may pass through the adjusting threaded hole of the first protrusion t1, and the end of the first T-shaped locking screw may abut against the end of the crucible clamp 1421.

[0044] Please refer to Figure 3 , Figure 7 and Figure 8 , Figure 8 This is a schematic diagram of the structure of a clamping plate b1 and a connecting plate b2 provided in an embodiment of the present invention. In an optional embodiment, the crucible clamping plate 1421 may include a clamping plate b1, a connecting plate b2 and a limiting pin b3; the clamping plate b1 is located inside the rotating adjusting ring 13 and is used to contact the outer wall of the crucible 20; the connecting plate b2 is fixedly connected to the clamping plate b1 and extends to the outside of the rotating adjusting ring 13; the connecting plate b2 is provided with a strip-shaped limiting groove k1 extending radially along the rotating adjusting ring 13, and the limiting pin b3 passes through the strip-shaped limiting groove k1 and is fixedly connected to the rotating adjusting ring 13.

[0045] The extending direction of the clamping plate b1 can be parallel to the extending direction of the outer wall of the crucible 20, so that the clamping force applied by the clamping plate b1 to the crucible 20 is more uniform. The extending direction of the connecting plate b2 can be perpendicular to the extending direction of the clamping plate b1. The connecting plate b2 can have two parallel strip-shaped limiting grooves k1, thereby improving the sliding stability of the connecting plate b2.

[0046] In one exemplary embodiment, the limiting pin b3 may include a second T-shaped locking screw, the rotating adjusting ring 13 may have a first limiting hole, the second T-shaped locking screw may pass through the strip-shaped limiting groove k1 and the first limiting threaded hole, and the limiting pin b3 is slidably connected to the connecting plate b2 through the strip-shaped limiting groove k1, so that the connecting plate b2 can slide along the extension direction of the strip-shaped limiting groove k1.

[0047] Please refer to Figure 9 , Figure 9 yes Figure 7 The schematic diagram of the cross-sectional structure of the crucible clamping and rotating device along position A1-A2 is shown. In an optional embodiment, the crucible clamping and rotating device may further include a bearing mechanism 15, and a tilting adjustment mechanism 12 including a tilting adjustment ring 121, which is rotatably connected to the load-bearing base 11. The bearing mechanism 15 has an inner ring 151 and an outer ring 152 that are rolled together. The inner ring 151 of the bearing mechanism 15 is fixedly connected to the rotating adjustment ring 13, and the outer ring 152 of the bearing mechanism 15 is fixedly connected to the tilting adjustment ring 121. The inner ring 151 of the bearing mechanism 15 can be bolted to the rotating adjustment ring 13, and the outer ring 152 of the bearing mechanism 15 can be bolted to the tilting adjustment ring 121.

[0048] The bearing mechanism 15 can reduce the frictional resistance when the rotating adjustment ring 13 and the flipping adjustment ring 121 are displaced relative to each other, so that the rotating adjustment ring 13 can be rotated around the first axis with less effort, and a single person can operate the crucible 20 to flip it.

[0049] The flipping adjustment ring 121 adopts a ring structure that can resist the torque generated when flipping the heavy crucible 20, thereby enhancing the overall rigidity, reducing deformation and vibration, and improving the stability of the crucible clamping and rotating device.

[0050] Please refer to Figure 1 , Figure 10 and Figure 11 , Figure 10 yes Figure 1 The diagram shows another view of the crucible clamping and rotating device. Figure 11 yes Figure 10The diagram shows an exploded view of the crucible clamping and rotating device. In an optional embodiment, the flipping adjustment mechanism 12 may further include a drive handle 122, a worm gear mechanism 123, and a second locking member 124. The worm gear mechanism is connected to the drive handle 122 and the flipping adjustment ring 121, respectively. The drive handle 122 drives the worm gear mechanism 123 to rotate the flipping adjustment ring 121 around a second axis. The second locking member 124 is movably connected to the load-bearing base 11 and can fix the flipping adjustment ring 121 at the target position.

[0051] For example, the flip-adjusting ring 121 may have a rotating shaft z1, and the load-bearing base 11 may have a support frame 111. The flip-adjusting ring 121 can be rotatably connected to the support frame 111 of the load-bearing base 11 via the rotating shaft z1. The worm gear is connected to the drive handle 122, and the worm wheel is fixedly connected to the rotating shaft z1 of the flip-adjusting ring 121. The second locking member 124 may include a first T-shaped locking pin z2 and a positioning plate z3. The positioning plate z3 can be fixedly connected to the rotating shaft z1 of the flip-adjusting ring 121, and the positioning plate z3 has a third positioning hole. The support frame 111 has a plurality of fourth positioning holes corresponding to the third positioning hole. When the flip-adjusting ring 121 rotates to a preset position, the first T-shaped locking pin z2 can pass through the third positioning hole and one of the fourth positioning holes to fix the flip-adjusting ring 121 at the current position.

[0052] Because the worm gear mechanism 123 has a reverse self-locking function, when the drive handle 122 is not driven, the transmission mechanism can automatically lock to prevent the heavy crucible 20 from accidentally overturning under gravity, thus ensuring the safety of personnel and equipment. At the same time, the second locking member 124 provides double insurance and rigid support, which can apply an additional mechanical constraint to the overturning adjustment ring 121 at the target position, enhancing the stability of the crucible clamping and rotating device.

[0053] Please refer to Figure 11 In an optional embodiment, the crucible clamping and rotating device may further include a third locking member 16; the rotating adjusting ring 13 is provided with a plurality of limiting plates extending to the flip adjusting ring 121, the limiting plates being provided with a first positioning hole k2, and the flip adjusting ring 121 being provided with a plurality of second positioning holes (not shown in the figure) corresponding to the first positioning hole k2; the third locking member 16 can be simultaneously inserted into one first positioning hole k2 and one second positioning hole to lock the relative position of the rotating adjusting ring 13 and the flip adjusting ring 121. The third locking member 16 may include a second T-shaped locking pin.

[0054] Please refer to Figure 5 and Figure 9In an optional embodiment, the crucible clamping and rotating device may further include a locking clip 17, and the crucible support 141 is detachably connected to the rotating adjusting ring 13 via the locking clip 17. The locking clip 17 can be bolted to the inner ring 151 of the bearing, thereby fixing it to the rotating adjusting ring 13. The crucible support 141 can be engaged with the locking clip 17, facilitating the installation and removal of the crucible support 141.

[0055] Please refer to Figure 9 and Figure 12 , Figure 12 This is a schematic diagram of another crucible clamping and rotating device provided in this embodiment of the present utility model. Optionally, the crucible clamping and rotating device further includes a side support structure 18. The side support structure 18 is detachably disposed on the flip adjustment ring 121. When the crucible 20 is in a horizontal position, the side support structure 18 can be installed on one side of the flip adjustment ring 121 and contact the lower side of the crucible 20 to provide auxiliary support.

[0056] When the crucible 20 is adjusted to a horizontal position, the side support structure 18 provides rigid auxiliary support to the lower side of the crucible 20. This distributes most of the weight of the crucible 20 and the heavy internal crystal material, reducing the load on the rotating adjustment ring 13 and its bearing mechanism 15, thereby enhancing the overall rigidity and stability of the crucible clamping and rotating device. Furthermore, during delicate crucible-wrapping operations requiring external force (such as hammering and shaping), this support effectively suppresses vibration and sagging deformation, providing a stable and reliable working platform for the process, further improving operational safety and process quality. It is understood that during the rotation of the crucible 20, the side support structure 18 can be removed from the tilting adjustment ring 121 to avoid affecting the rotation of the crucible 20. The side support structure 18 can be connected to the tilting adjustment ring 121 via bolts.

[0057] In one exemplary embodiment, the side support structure 18 has multiple mounting positions from top to bottom, thereby allowing the side support structure 18 to be adjusted up and down to accommodate crucibles 20 of different sizes.

[0058] Please refer to Figure 11 Optionally, the bottom of the load-bearing base is provided with casters 112. In this way, the load-bearing base can drive the tilting adjustment mechanism 12 to move in translation, which in turn can drive the rotating adjustment ring 13 and the crucible fixing mechanism 14 to move in translation, which can improve the flexibility of the crucible clamping and rotating device and facilitate the adjustment of the placement position of the crucible clamping and rotating device.

[0059] In one exemplary embodiment, this utility model provides a method for using a crucible clamping and rotating device, which may include the following steps: Step 201: Rotate the drive handle 122 to adjust the tilting adjustment ring 121 to a horizontal position via the worm gear mechanism 123, and fix it using the second locking member 124. Subsequently, install the detachable crucible support 141 onto the rotating adjustment ring 13, and assemble it with the appropriate crucible clamping member 142 according to the specifications of the crucible 20.

[0060] Step 202: Place the seed crystal and the crystal material vertically into the seed crystal support tray (not shown) of the crucible support base 141, put on the platinum crucible 20, adjust each crucible clamp 142 radially to make it fit tightly against the outer wall of the crucible 20, and then use the first locking member 1422 to lock and fix the crucible clamp 142 to prevent the crucible 20 from shifting during rotation.

[0061] Step 203: Keep the flipping adjustment ring 121 in a horizontal position and manually seal the top of the crucible 20.

[0062] Step 204: Loosen the second locking member 124, rotate the drive handle 122, and rotate the flipping adjustment ring 121 by about 90° to change the square crucible 20 from a vertical state to a horizontal state, and then re-lock the second locking member 124. Then perform the seed crystal covering operation; when flipping is required, loosen the third locking member 16 of the rotation adjustment ring 13, rotate it 90°, and then lock it again. Repeating this operation will allow the crucible 20 to rotate on all four sides.

[0063] Step 205: After the crucible wrapping operation is completed, turn the drive handle 122 to rotate the flipping adjustment ring 121 in the opposite direction by about 90°, so that the crucible 20 returns from the horizontal state to the vertical state. At this time, the platinum crucible 20 containing the crystal material can be taken out, and the crucible wrapping process is completed.

[0064] It should be noted that the dimensions of the areas may have been exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element is referred to as "on top of" another element, it can be directly on the other element, or there may be intermediate elements. Additionally, it is understood that when an element is referred to as "below" another element, it can be directly below the other element, or there may be more than one intermediate element. Furthermore, it is also understood that when an element is referred to as "between" two elements, it can be the only layer between the two elements, or there may be more than one intermediate element. Similar reference numerals throughout indicate similar elements.

[0065] In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
