Description

Technical Field

[0001] This utility model relates to the field of single crystal production technology, and in particular to a quartz feeding cylinder transfer device. Background Technology

[0002] In the process of pulling single crystals, polycrystalline silicon raw materials are first added to a quartz crucible through initial loading and subsequent re-loading. Initial loading involves placing polycrystalline silicon into the quartz crucible according to the technical specifications, then hoisting it into the single crystal furnace to melt the raw material at high temperatures. Once the melt reaches a certain stage, the polycrystalline silicon needs to be re-loaded into the quartz crucible. This re-loading process uses a quartz feeding cylinder. The quartz feeding cylinder is loaded in a dedicated loading workshop and then placed on a special transport vehicle to be transferred to the single crystal furnace for further loading.

[0003] Existing feeding cylinders are usually made of quartz material. The amount of material that can be loaded in a single feeding cylinder is limited. When a single crystal furnace is refilled, multiple feeding cylinders need to be used for alternating feeding. That is, after each cylinder is filled, the empty cylinder needs to be removed and another feeding cylinder needs to be hung up again. During the process of picking up and putting down the feeding cylinders, the position of the transfer car needs to be moved so that the feeding cylinders can be accurately picked up and put down from the transfer car. Summary of the Invention

[0021] This application provides a quartz feeding cylinder transfer device, see [link]. Figure 1 The figure shown is a three-dimensional structural diagram of the transfer device provided in the embodiment of this application. Figure 1 Six quartz feeding cylinders 26 were placed on the intermediate transfer device. Figure 2 The figure shown is a three-dimensional structural view of the transfer device provided in this application embodiment without the quartz feeding cylinder 26 placed therein.

[0022] The transfer device mainly includes a frame 1. In the embodiment shown in the figure, the frame 1 is a cuboid frame structure, consisting of a lower base plate 101, an upper support plate 102, and four uprights 103. The lower base plate 101 and the upper support plate 102 are rectangular plates arranged opposite each other, and the four corners between the lower base plate 101 and the upper support plate 102 are connected by four vertically arranged uprights 103. Four wheels 104 are installed at the four corners of the bottom of the frame 1 (i.e., the lower surface of the lower base plate 101) to facilitate manual pushing or pulling by an electric trolley.

[0023] A circular rotating platform 2 is mounted on the lower base plate 101 of the frame 1. The rotating platform 2 is driven to rotate by a motor drive device 3. Figure 3The diagram shows the structure of a motor drive device 3 according to an embodiment of this application. In one specific embodiment, a first groove 101.1 is formed in the center of the upper surface of the lower base plate 101 of the frame 1. In the embodiment shown in the figure, the first groove 101.1 is a circular groove. A turntable shaft 105 is arranged in the center of the first groove 101.1, and a rotatable driven sprocket 301 is mounted on the turntable shaft 105. A reduction motor 302 is mounted on the bottom edge of the lower base plate 101 of the frame 1. The drive shaft of the reduction motor 302 passes through the lower base plate 101 and is mounted on a drive sprocket 303. The drive sprocket 303 and the driven sprocket 301 are in the same plane and are connected by a transmission chain 304. The upper surface of the driven sprocket 301 is fixedly connected to a circular rotating platform 2. The driven sprocket 301, the reduction motor 302, the drive sprocket 303, and the transmission chain 304 constitute the motor drive device 3; the reduction motor 302 drives the rotating platform 2 to rotate. In this application, a battery is installed on the frame 1 to supply power to electrical equipment. Without interfering with other structures on the frame 1, the battery in this application can be installed at any position on the frame 1. For example, the battery can be installed in the four uprights 103.

[0024] like Figure 1 , Figure 2 As shown, the upper surface of the rotating platform 2 is arranged in a ring array with multiple annular PTFE positioning rings 4; the bottom of the quartz feeding cylinder 26 can be placed in the circular hole in the middle of the PTFE positioning ring 4, restricting the position of the quartz feeding cylinder 26. In the embodiment shown in the figure, the upper surface of the rotating platform 2 is arranged in a ring array with six annular PTFE positioning rings 4, and the transfer device provided in this embodiment can transfer six quartz feeding cylinders 26 at a time for feeding.

[0025] A circular first through hole 102.1 is formed in the center of the upper support plate 102 of the frame 1, and the first through hole 102.1 is directly opposite to the rotating platform 2 below. When placing the quartz feeding cylinder 26, the quartz feeding cylinder 26 is passed through the first through hole 102.1 in the center of the upper support plate 102 from top to bottom, and the bottom of the quartz feeding cylinder 26 is placed in the circular hole in the middle of the PTFE positioning ring 4. The quartz feeding cylinder 26 is placed vertically on the frame 1.

[0026] like Figure 2 As shown, an inner support column 5 is vertically arranged in the center of the upper surface of the rotating platform 2. A circular inner support plate 6 is arranged on the top of the inner support column 5. The inner support plate 6 is concentric with the first through hole 102.1 in the center of the upper support plate 102. In the embodiment shown in the figure, the upper surface of the inner support plate 6 is flush with the upper surface of the upper support plate 102. The gap between the inner support plate 6 and the first through hole 102.1 is larger than the diameter of the quartz feeding cylinder 26, allowing the quartz feeding cylinder 26 to freely pass through the annular channel formed between them.

[0027] In addition, multiple arc-shaped limiting plates 7 are arranged in a ring array on the inner support plate 6. The number of arc-shaped limiting plates 7 is the same as the number of PTFE positioning rings 4, and they are arranged one-to-one. Figure 4 The diagram shows the use of the arc-shaped limiting plate 7 to limit the quartz feeding cylinder 26 according to an embodiment of this application. In one specific embodiment of this application, six arc-shaped limiting plates 7 are arranged in a circular array on the lower surface of the inner support plate 6, each arc-shaped limiting plate 7 corresponding to the PTFE positioning ring 4 below it; the length of the arc-shaped limiting plate 7 is less than the length of a semicircle, and the opening of the arc-shaped limiting plate 7 faces the quartz feeding cylinder 26. The arc-shaped limiting plate 7 is used to hold the outer side of the quartz feeding cylinder 26 to prevent the quartz feeding cylinder 26 from tilting to both sides.

[0028] Furthermore, in one specific embodiment of this application, the arc-shaped limiting plate 7 can be designed to be movable, used to push the quartz feeding cylinder 26 toward the inner wall of the first through hole 102.1, so that the quartz feeding cylinder 26 is close to the inner wall of the first through hole 102.1 and fixed thereto, so as to prevent it from shaking during movement.

[0029] The specific methods are as follows: Figure 5 The diagram shows the structure of the movable arc-shaped limiting plate 7 in this embodiment. A hexagonal prism-shaped support base 8 is provided on the lower surface of the inner support plate 6. A moving mechanism is installed on each of the six sides of the support base 8, and an arc-shaped limiting plate 7 is installed on each moving mechanism. The moving mechanisms drive the arc-shaped limiting plate 7 to move radially along the first through hole 102.1. The arc-shaped limiting plate 7 moves towards the quartz feeding cylinder 26 and contacts the side of the quartz feeding cylinder 26, while the other side of the quartz feeding cylinder 26 rests against the inner wall of the first through hole 102.1. Preferably, the arc-shaped limiting plate 7 is made of rubber, and an annular high-temperature and wear-resistant PTFE ring 9 is installed on the inner wall of the first through hole 102.1.

[0030] like Figure 6 The diagram shown is a structural illustration of a moving mechanism provided in an embodiment of this application. The moving mechanism includes an L-shaped mounting base 10. Two parallel first guide rails 11 are mounted on the lower surface of the mounting base 10. An electric telescopic cylinder 12 is mounted below the first guide rails 11 and is fixed to the mounting base 10. A sliding seat 13 is mounted at the piston rod end of the electric telescopic cylinder 12. Two first sliders 14 are mounted on the upper surface of the sliding seat 13 and are slidably mounted on the two first guide rails 11. Two opposing buffer plates 15 are mounted on the front side of the sliding seat 13, connected by a buffer spring 16. The front of the forward buffer plate 15 is connected to the midpoint of an arc-shaped limiting plate 7. The arc-shaped limiting plate 7 is moved by the electric telescopic cylinder 12; the buffer spring 16 provides elastic compression and limiting of the quartz feeding cylinder 26.

[0031] The method of using the aforementioned transfer device is as follows: Six empty quartz feeding cylinders 26 are placed in the six PTFE positioning rings 4 of the frame 1; loading is carried out in the loading workshop. During the loading process, after each cylinder is loaded, the rotating platform 2 is controlled to rotate, so that the adjacent empty feeding cylinder is rotated to the discharge port of the feeding equipment for feeding. This operation is repeated until all six quartz feeding cylinders 26 are loaded. Afterwards, the equipment is moved manually or pulled by an electric trolley to the single crystal furnace feeding position; the feeding process is as follows: the operator uses a hook to connect the tungsten wire rope counterweight in the single crystal furnace to the connecting rod on the currently aligned feeding cylinder, and then lowers the feeding cylinder to feed according to the single crystal furnace feeding operation procedure. After the feeding cylinder is finished, the empty cylinder is returned to its original position on the frame 1; then, the operator controls the rotating platform 2 to rotate the adjacent feeding cylinder containing raw materials to the position aligned with the tungsten wire rope, and continues the next feeding operation. This process is repeated until the feeding of all feeding cylinders is completed.

[0032] The transfer device provided in this application can load 6 feeding cylinders at a time. Compared with the existing method of loading one feeding cylinder per trolley, it greatly reduces the time for changing feeding cylinders, avoids the tedious operation of repeatedly picking up and putting down feeding cylinders, significantly improves the feeding efficiency in the single crystal production process, and thus improves the overall production efficiency.

[0033] Furthermore, in one specific embodiment of this application, a hand-cranked screw lifting frame 17 can also be provided on the bottom surface of the lower base plate 101 of the frame 1. For example... Figure 7 The diagram shown is a structural illustration of the hand-cranked screw lifting frame 17 provided in an embodiment of this application. The hand-cranked screw lifting frame 17 is installed in the center of the bottom surface of the lower base plate 101, located between the four wheels 104. Figure 8 The diagram shows a detailed structural representation of the hand-cranked screw lifting frame 17 provided in this embodiment. The hand-cranked screw lifting frame 17 mainly includes an upper support 18, a lower support 19, X-shaped hinged connecting rods 20, and a drive screw 21. The upper support 18 and lower support 19 are rectangular frames, arranged opposite each other. The upper support 18 is fixedly connected to the bottom surface of the lower base plate 101, and support feet 22 are provided at the four corners of the lower support 19. Two sets of X-shaped hinged connecting rods 20 are symmetrically arranged on the left and right sides between the upper support 18 and lower support 19, and the two sets of X-shaped hinged connecting rods 20 are connected by two crossbeams 23. The drive screw 21 passes through a screw nut 24 on the crossbeam 23, and a hand crank 25 is installed at one end of the drive screw 21. Rotating the drive screw 21 drives the X-shaped hinged connecting rods 20 to extend or retract.

[0034] When the transfer device of this application is loading materials in the loading workshop, and when it is changing cylinders for material at the single crystal furnace feeding position, after the transfer device stops at the designated position, it first uses the drive screw 21 to make the support foot 22 touch the ground, at which time the four wheels 104 are off the ground; the support device of the support foot 22 can prevent the equipment from moving; then the material loading or cylinder changing operation is carried out.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
