[0001] This invention belongs to the field of crucible transportation technology, and particularly relates to an automatic transportation device for the production of quartz crucibles. Background Technology

[0002] Quartz crucibles are high-temperature melting containers made of high-purity quartz sand. They are characterized by high temperature resistance, high chemical stability, and low coefficient of thermal expansion. They are mainly used in the photovoltaic and semiconductor industries for single-crystal silicon pulling, high-purity material melting, and crystal growth processes. During their production, appropriate transportation devices are needed to transport them in order to transfer them between different production processes.

[0003] Document CN222006536U discloses a crucible transfer device, relating to the field of crucibles. It includes a rotating device, a transport device disposed on the upper part of the rotating device, and a gripping mechanism disposed on the transport device. The rotating device allows the crucible transfer device to rotate 360 ​​degrees, the transport device allows the crucible to move horizontally, and the gripping mechanism is a three-jaw gripping mechanism, making the gripping more secure and stable, preventing the crucible from shaking. This crucible transfer device is flexible, and the transfer direction is no longer singular; the movement direction can be adjusted according to needs, saving manpower and resources and improving work efficiency. However, in actual transfer processes, different subsequent processing steps require different placement postures for the quartz crucible, which traditional transport devices cannot meet. Furthermore, impurities generated during the production process are easily retained inside the formed quartz crucible, affecting the overall quality of the quartz crucible. Therefore, improvements are needed. Summary of the Invention

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, by setting up a clamping and flipping assembly, the drive roller and the auxiliary roller can gradually fit and limit the outer surface of the quartz crucible during the opposing movement of the moving box, thereby ensuring that the crucible is subjected to uniform force during clamping, avoiding surface scratches or damage caused by local stress concentration, and improving the protection of the quartz crucible. At the same time, through the meshing transmission between the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear, the synchronous rotation of the two clamping parts can be realized. On the one hand, it can improve the steering torque and ensure that the movement of the quartz crucible is smooth, and the crucible can be accurately flipped 180 degrees in a short time. On the other hand, the synchronous rotation of the two clamping parts can ensure that the force on the quartz crucible is consistent when it is flipped, avoiding damage to the quartz crucible caused by the difference in rotation between the two clamping parts. At the same time, by adjusting the orientation of the quartz crucible, it can ensure that the opening is quickly switched to the downward state, thereby removing internal residual impurities and improving the quality of the finished product.

[0028] 2. In this invention, by setting up a drive cleaning component, the third drive motor, through the cooperation of drive gears, transmission gears, drive rollers, and auxiliary rollers, enables the quartz crucible to rotate stably in a concentric axial direction. During this process, the linkage gear, in conjunction with the fixed gear plate, drives the counterweight to vibrate eccentrically, thereby applying high-frequency micro-amplitude vibration during the crucible's rotation. This effectively peels off and removes impurities adhering to the inner wall, significantly improving cleaning efficiency and thoroughness. The combination of the quartz crucible's rotation and its self-vibration not only avoids the residual dead corners caused by traditional single cleaning methods but also completes the automated cleaning process without manual intervention, ultimately ensuring the purity and surface integrity of the quartz crucible and improving the quality of the finished product.

[0029] 3. In this invention, by setting an auxiliary feeding component and forming an inner support-type limiting gripping structure through the outward expansion of the outer support plate, the outer support plate is tightly fitted to the inner wall of the quartz crucible. This not only avoids damage to the outer wall of the crucible caused by traditional clamping methods but also enhances gripping stability. At the same time, by adjusting the movement distance of the outer plate through or controlling the movement stroke of the second lead screw seat, the outer support plate can be adapted to quartz crucibles of different specifications, improving the overall applicability of the device. In addition, the electric push rod allows the quartz crucible to be vertically lowered into the packaging box, effectively solving the interference problem of packing in a narrow space. This enables the device to meet different feeding environments and improves the flexibility of its use. Attached Figure Description

[0046] The specific implementation method is as follows: By setting up the clamping and flipping assembly 3, the drive roller 501 and the auxiliary roller 502 can gradually fit and limit the outer surface of the quartz crucible during the opposing movement of the moving box 301, thereby ensuring that the crucible is subjected to uniform force during clamping, avoiding surface scratches or damage caused by local stress concentration, and improving the protection of the quartz crucible. At the same time, through the meshing transmission between the first bevel gear 309, the second bevel gear 312, the third bevel gear 314 and the fourth bevel gear 315, the synchronous rotation of the two clamping parts 303 can be realized. On the one hand, it can improve the steering torque and ensure the smooth movement of the quartz crucible, and can complete the precise 180-degree flip of the crucible in a short time. On the other hand, the synchronous rotation of the two clamping parts 303 can ensure that the force on the quartz crucible is consistent when it is flipped, avoiding damage to the quartz crucible caused by the difference in rotation of the two clamping parts 303. At the same time, by adjusting the orientation of the quartz crucible, it can ensure that the opening is quickly switched to the downward state, thereby removing internal residual impurities and improving the quality of the finished product.

[0047] The drive cleaning assembly 5 includes a drive roller 501 and two auxiliary rollers 502. A clamping member 303 has multiple rotating grooves on one side. The drive roller 501 and the two auxiliary rollers 502 are rotatably connected to the rotating grooves via mounting bases. Two symmetrically distributed circular shafts 509 are rotatably connected inside the auxiliary rollers 502. Two symmetrically distributed connecting rods 511 are connected to one side of each circular shaft 509. The ends of the two connecting rods 511 furthest from the circular shaft 509 are connected to the same counterweight 510. Both ends of the circular shaft 509 extend to the outside of the auxiliary rollers 502 and are connected to linkage gears 507. Two linkage gears 507 on the same side... 7. The outer peripheral side is meshed with the same fixed gear disk 506. The fixed gear disk 506 is connected to one side of the mounting base. Both sides of the auxiliary roller 502 are connected to drive shafts 508. The drive shafts 508 pass through the fixed gear disk 506 and are rotatably connected to the mounting base. One side of the clamping member 303 is fixedly mounted with a third drive motor 503 through a third mounting plate. One end of the output shaft of the third drive motor 503 is connected to a drive gear 504. One side of the drive gear 504 is meshed with a transmission gear 505. The bottom of the transmission gear 505 is connected to a rotating shaft. One end of the rotating shaft extends to the other side of the mounting base and is connected to one side of the drive roller 501.

[0048] The specific implementation method is as follows: By setting up the drive cleaning component 5, the third drive motor 503, through the cooperation between the drive gear 504, the transmission gear 505, the drive roller 501 and the auxiliary roller 502, enables the quartz crucible to rotate stably in a concentric axis. During this process, the linkage gear 507, in conjunction with the fixed gear plate 506, drives the counterweight 510 to vibrate eccentrically, so that high-frequency micro-amplitude vibration is applied during the rotation of the crucible, effectively peeling off and discharging impurities attached to the inner wall, significantly improving cleaning efficiency and thoroughness. The combination of the quartz crucible's rotation and its self-vibration not only avoids the residual dead corners caused by traditional single cleaning methods, but also completes the automated cleaning process without manual intervention, ultimately ensuring the purity and surface integrity of the quartz crucible and improving the quality of the finished product.

[0049] The bottom of the connecting frame 6 is connected to an electric push rod 401, the bottom of which is connected to a protective box 402. The bottom of the protective box 402 is connected to a protective shell 409. An adjusting screw 407 is rotatably connected inside the protective shell 409. Two symmetrically arranged second screw seats 408 are connected to the outer surface of the adjusting screw 407. A connecting rod 405 is hinged to the outer surface of the second screw seats 408. The end of the connecting rod 405 away from the second screw seats 408 extends to the protective shell 409 and is hinged to an outer support plate 404. The outer support plate 404 extends outward to press against the inner wall of the quartz crucible. The protective housing 402 has an outward expansion limit. A fixed motor 403 is fixedly installed inside the protective housing 402. One end of the adjusting screw 407 extends into the protective housing 402 and is connected to one end of the output shaft of the fixed motor 403. The outer surface of the protective housing 409 has multiple through slots arranged in a circumferential array. The connecting rod 405 is slidably connected in the through slots. The adjusting screw 407 is symmetrically arranged along its own center position, and the threads on both sides are opposite. The outer surface of the protective housing 409 is connected to multiple telescopic rods 406 arranged in a circumferential array. The other end of the telescopic rod 406 is connected to one side of the outer support plate 404.

[0050] The specific implementation method is as follows: By setting up an auxiliary feeding component 4, the outer support plate 404 expands outward to form an inner support-type limiting gripping structure, so that the outer support plate 404 fits tightly against the inner wall of the quartz crucible. This not only avoids damage to the outer wall of the crucible caused by traditional clamping methods, but also enhances gripping stability. At the same time, by adjusting the movement distance of the outer plate through or controlling the movement stroke of the second lead screw seat 408, the outer support plate 404 can be adapted to quartz crucibles of different specifications, improving the overall applicability of the device. In addition, with the help of the electric push rod 401, the quartz crucible can be vertically lowered into the packaging box, effectively solving the interference problem of packing in a narrow space. This allows the device to meet different feeding environments and improves the flexibility of the device.

[0051] Working principle: During use, the operator moves the connecting frame 6 to various positions on the production line via the conveyor guide rail 1 and the connecting telescopic device 2. When the connecting frame 6 moves directly above the quartz crucible, the operator activates the connecting telescopic device 2, causing the connecting frame 6 to move downwards. This causes the moving box 301 to move downwards and position itself on both sides of the quartz crucible. Then, the first drive motor 304 drives the moving screw 306 to rotate. The moving screw 306 drives the first screw seat 305 to move inwards in opposite directions. 1. The connecting block 302, clamping component 303, driving roller 501, and auxiliary roller 502 move towards the quartz crucible. During this process, the moving box 301 slides on the outer surface of the rotating rod 307 via the rotating sleeve 311, causing the driving roller 501 and auxiliary roller 502 assembly to gradually come into contact with the outer surface of the quartz crucible. After the auxiliary roller 502 and driving roller 501 have reached the contact limit with the outer surface of the quartz crucible, the connecting telescopic device 2 moves the quartz crucible upward via the connecting frame 6, completing the clamping of the quartz crucible. Afterwards, the staff decides whether to flip the quartz crucible based on its orientation. If the crucible's opening is facing downwards, it is not flipped temporarily; if the opening is facing upwards, it is flipped. During this process, the second drive motor 308 starts, driving the rotating rod 307 to rotate. The rotating rod 307 drives the rotating sleeve 311 to rotate, which in turn drives the first bevel gear 309 to rotate. The first bevel gear 309 then drives the second bevel gear 312 to rotate. The second bevel gear 312 then drives... The rotating connecting shaft 310 drives the third bevel gear 314 to rotate, which in turn drives the fourth bevel gear 315 to rotate. The fourth bevel gear 315, through the rotating shaft 313 and the connecting block 302, drives the clamping member 303 to rotate. The two cooperating clamping members 303 cause the quartz crucible to change its orientation, so that the opening of the quartz crucible faces downward, thereby allowing residual impurities inside the quartz crucible to fall off, ensuring the overall cleanliness of the quartz crucible, and realizing the adjustment of the quartz crucible's posture to facilitate adaptation to subsequent processes.

[0052] When the quartz crucible is adjusted by the clamping and flipping assembly 3 so that its opening faces downwards, the operator starts the third drive motor 503. The third drive motor 503 drives the drive gear 504 to rotate, the drive gear 504 drives the transmission gear 505 to rotate, and the transmission gear 505 drives the drive roller 501 to rotate. The co-rotation of the two drive rollers 501, combined with the auxiliary drive roller 502, enables the quartz crucible to rotate concentrically. During this process, the auxiliary roller 502 rotates on its own axis, driving the... Two round shafts 509 rotate around a fixed gear disk 506. The round shafts 509 drive the linkage gear 507 to revolve on the fixed gear disk 506, causing the linkage gear 507 to rotate. The linkage gear 507 drives the round shafts 509 to rotate. The round shafts 509 drive the counterweight 510 to rotate eccentrically through the connecting rod 511, causing the auxiliary roller 502 to vibrate eccentrically, thereby causing vibration of the quartz crucible. Combined with the axial rotation of the quartz crucible itself, this can improve the removal and cleaning of impurities inside the quartz crucible, ensuring the overall quality of the quartz crucible.

[0053] When the connecting frame 6 moves the quartz crucible to the required position, the operator can adjust the placement posture of the quartz crucible, i.e., the orientation of the opening, according to actual requirements. Furthermore, when it is necessary to pack the quartz crucible, the operator can first adjust the opening of the quartz crucible to face upwards. Then, the push rod is activated, and the electric push rod 401 moves the protective box 402 and the protective outer shell 409 downwards, allowing multiple outer support plates 404 to enter the quartz crucible. Afterwards, the fixed motor 403 is activated, driving the adjusting screw 407 to rotate. The adjusting screw 407 then moves the second screw seat 408 towards the center position of the adjusting screw 407. The movement of the second lead screw seat 408 causes multiple connecting rods 405 to move. Two connecting rods 405 on the same side, through their own position changes, cooperate with the telescopic rod 406 to drive the outer support plate 404 to expand outward, thereby squeezing and fitting the inner wall of the quartz crucible, thus realizing the inner support type limiting gripping of the quartz crucible. Then, through mechanical transmission, the moving box 301 and the clamping part 303 are moved away from the quartz crucible to avoid interference during the packing of the quartz crucible. The electric push rod 401, in conjunction with the outer support plate 404, drives the quartz crucible to move downward, and the quartz crucible can fall into the packaging box, completing the packing operation in a confined environment and improving the adaptability to the transportation environment of the quartz crucible.
