[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] In the crystal pulling process, it is necessary to regularly add raw silicon blocks or silicon wafers into the crystal pulling furnace through a quartz feeding tube. In this process, a movable carrier is needed to carry the quartz tube. When adding materials, the carrier moves the feeding tube filled with raw materials to a position close to the crystal pulling furnace, and then lifts the feeding tube to the main furnace chamber through the hanging wire in the middle of the garbage furnace auxiliary chamber, and then slowly lowers it to a position close to the molten silicon material for feeding. After the feeding is completed, the feeding tube is lifted to the upper furnace tube, the auxiliary chamber is rotated, and the lifting head drives the hanging wire to descend to place the quartz tube on the carrier. In the prior art, the locking mechanism on the carrier for transporting the quartz tube is relatively cumbersome to operate, and is mainly locked and unlocked manually, which is cumbersome to operate, inefficient, and has certain safety hazards. Although clamping control can be performed by setting an electric drive unit and an intelligent control unit, this will increase the cost of the equipment.

[0030] In order to solve the above problems, this embodiment provides a carrier for a quartz tube and a method of using the same.

[0031] like Figure 1 As shown, the present embodiment provides a carrier for a quartz tube, comprising a moving mechanism 1 and a clamping mechanism 2 disposed on the moving mechanism 1 .

[0032] Combination Figure 2 The mobile mechanism 1 includes a mobile chassis 11 and a mobile frame 12 installed on the mobile chassis 11.

[0033] The mobile chassis 11 includes a base and mobile wheels fixed to the bottom of the base. There may be multiple mobile wheels, and the multiple mobile wheels may adopt a four-wheel omnidirectional mobile design to achieve omnidirectional mobility. In practical applications, the mobile chassis 11 may adopt an intelligent mobile chassis with autonomous mobility.

[0034] The mobile frame 12 includes columns connected to the mobile chassis 11 and beams disposed on the top of the columns and connected to the columns. The columns are the vertical support parts of the mobile frame 12, connecting the mobile chassis 11 and the top beams to provide the necessary vertical support force. The beams are horizontal members connecting the columns, which can provide additional stability.

[0035] In a further embodiment, a handrail 13 is provided on one side of the mobile frame 12. When the mobile chassis 11 does not have the ability to move autonomously, the carrier can be pushed or pulled manually to move.

[0036] Combination Figure 3 The clamping mechanism 2 includes a linkage assembly 21 and a plurality of clamping assemblies 22. The plurality of clamping assemblies 22 are arranged along the height direction of the linkage assembly 21.

[0037] The linkage assembly 21 includes a linkage bracket 211, a linkage support plate 212, a support chassis 213, a linkage rod 214, and a plurality of sliding supports 215. The linkage bracket 211 is installed on the mobile frame 12 of the mobile mechanism 1. The linkage support plate 212 is arranged on one side of the bottom of the linkage bracket 211. The support chassis 213 is arranged on the linkage support plate 212 in a resettable and liftable manner. The bottom end of the linkage rod 214 is fixedly connected to the support chassis 213. A plurality of sliding supports 215 are fixed to the linkage bracket 211 along the height direction. The top end of the linkage rod 214 passes through the sliding supports 215 in sequence from bottom to top, and is slidably connected to the sliding supports 215.

[0038] like Figure 4 As shown, this embodiment is provided with three clamping assemblies 22, and the three clamping assemblies 22 can clamp the quartz tube 3 at multiple heights. In theory, the number of clamping assemblies 22 can be determined according to actual needs and design requirements, and is not necessarily limited to three. If three clamping assemblies 22 can already meet the clamping requirements of the quartz tube 3, then it may not be necessary to add more clamping assemblies 22. When designing the number of clamping assemblies 22, it is necessary to consider the distribution of the clamping assemblies 22 to ensure the balance and stability of the quartz tube 3 during the clamping process.

[0039] like Figure 5 As shown, the clamping assembly 22 includes a clamping fixture 221 and a clamping closing member 222. The clamping fixture 221 is fixedly mounted on one side of the linkage bracket 211. The linkage rod 214 is disposed on the other side of the linkage bracket 211. The clamping closing member 222 is disposed at both ends of the clamping fixture 221. A clamping space 223 is formed between the clamping closing member 222 and the clamping fixture 221. In addition, the clamping closing member 222 is transmission-connected to the linkage rod 214 of the linkage assembly 21. When the linkage rod 214 is synchronously raised and lowered with the supporting chassis 213, the clamping closing members 222 of each clamping assembly 22 are synchronously expanded or closed to achieve the expansion or reduction of the clamping space 223.

[0040] In a further embodiment, in combination Figure 5 and Figure 6The clamping fixture 221 includes a clamping fixing portion 2211 and a clamping positioning portion 2212. The clamping fixing portion 2211 is fixed to the linkage bracket 211. The clamping positioning portion 2212 is fixedly connected to the clamping fixing portion 2211. Among them, the clamping positioning portion 2212 is an arc-shaped structure and is bent toward a side close to the clamping fixing portion 2211. The clamping positioning portion 2212 of the arc-shaped structure can, on the one hand, play a role in positioning and guiding, and can play a centering role when the clamping assembly 22 clamps the quartz tube 3, improve the clamping effect, and can play a guiding role in the lifting process of the quartz tube 3; on the other hand, it can also increase the clamping area between it and the quartz tube 3, evenly distribute the clamping force, avoid applying excessive pressure to the local area of ​​the quartz tube 3, and thus reduce the risk of breakage or damage. The arc-shaped structure can provide stable support, help keep the position of the quartz tube 3 fixed, and prevent it from moving or tilting when subjected to force. The arc-shaped structure design can adapt to quartz tubes 3 of different diameters, providing a certain degree of flexibility, making the clamping and positioning portion 2212 more universal.

[0041] like Figure 5 As shown, the clamping and closing member 222 includes a clamping portion 2221 and a connecting portion 2222. The clamping portion 2221 is an arc-shaped structure. The connecting portion 2222 is fixed to one end of the clamping portion 2221. In practical applications, the clamping portion 2221 and the connecting portion 2222 of the clamping and closing member 222 generally adopt an integrated structure. The connecting portion 2222 extends to the outside of the clamping portion 2221. The connecting portion 2222 includes a first position 22221 close to one end of the clamping portion 2221 and a second position 22222 away from the clamping portion 2221. The connecting portion 2222 of the clamping and closing member 222 is hinged to the clamping positioning portion 2212 at the first position 22221 and realizes rotational opening and closing with the clamping and closing member 222. The connecting portion 2222 realizes the transmission connection of the linkage rod 214 at the second position 22222 , so as to convert the up-and-down movement of the linkage rod 214 into the opening-and-closing movement of the clamping and closing member 222 .

[0042] Furthermore, if Figure 6As shown, the clamping assembly 22 also includes a first connecting rod 224, a second connecting rod 225, a clamping support 226, a clamping movable seat 227, and two third connecting rods 228. One end of the first connecting rod 224 is hinged to the linkage rod 214. The other end of the first connecting rod 224 is hinged to one end of the second connecting rod 225. The clamping support 226 is fixedly mounted on the clamping fixing portion 2211 of the clamping fixing member 221. The clamping movable seat 227 is movably arranged on the clamping support 226. The clamping movable seat 227 is fixedly connected to the other end of the second connecting rod 225. The two third connecting rods 228 are respectively hinged to the clamping movable seat 227. Among them, the second connecting rod 225 is slidably connected to the clamping support 226. The two third connecting rods 228 in each group of clamping assemblies 22 are symmetrically arranged about the second connecting rod 225 of the same group. For each third link 228, one end of the third link 228 is hinged to one end on the same side of the clamping and moving seat 227, and the other end of the third link 228 is hinged to the clamping portion 2221 of the clamping and closing member 222 on the corresponding same side at the second position 22222. The first link 224 is configured to drive the second link 225 and the clamping and moving seat 227 to move in a direction perpendicular to the lifting and lowering of the linkage rod 214 during the lifting and lowering process of the linkage rod 214, so that the two third links 228 open and close, and then the clamping and closing member 222 opens and closes. It is obvious that the moving direction of the second link 225 is perpendicular to the lifting and lowering direction of the linkage rod 214. In addition, when the linkage rod 214 is lifted and lowered, the first link 224 moves accordingly and rotates. The movement of the first link 224 is transmitted to the clamping support 226 through the second link 225. Since the second link 225 and the clamping support 226 are slidably connected, the clamping support 226 can slide along a fixed path. The movement of the second connecting rod 225 is further transmitted to the clamping and closing member 222 through the third connecting rod 228. It can be understood that the movement of the linkage rod 214 causes the relative position of the first connecting rod 224 and the second connecting rod 225 to change, and then affects the position of the clamping and closing member 222 through the third connecting rod 228. Specifically, when the linkage rod 214 descends, the angle between the first connecting rod 224 and the second connecting rod 225 increases, and the distance between the end of the first connecting rod 224 and the second connecting rod 225 and the clamping support 226 decreases, that is, the second connecting rod 225 pushes the clamping movable seat 227 to move to the side close to the clamping fixed member 221, and expands the third connecting rod 228 to push the clamping and closing member 222 to close and clamp the quartz tube 3. Generally, the length of the third connecting rod 228 is greater than the connecting portion 2222 to provide a greater clamping force. On the contrary, when the linkage rod 214 rises, the angle between the first link 224 and the second link 225 decreases, and the distance between the hinged ends of the first link 224 and the second link 225 and the clamping support 226 increases, that is, the second link 225 pulls the clamping movable seat 227 away from the clamping fixed part 221, and closes the third link 228 to pull the clamping closing part 222 to expand and release the clamping of the quartz tube 3.Through the coordinated action of the connecting rod and the hinge structure, the clamping assembly 22 can achieve stable clamping and release of the quartz tube 3.

[0043] In a further embodiment, Figure 7 As shown, a connecting piece 2141 is provided at the bottom of the linkage rod 214 to be fixedly connected to the supporting chassis 213. Specifically, the connecting piece 2141 can be in the form of a rod, one end of which is fixedly connected to the supporting chassis 213, and the other end of which is fixedly connected to the linkage rod 214. The fixed connection can be in the form of a threaded connection, a welding connection, and a pin connection. In this way, the synchronous lifting and lowering of the supporting chassis 213 and the linkage rod 214 can be achieved.

[0044] In addition, if Figure 7 As shown, the linkage assembly 21 also includes a plurality of positioning pins 216 fixed to the bottom of the supporting chassis 213 and an elastic member 217 provided between the linkage support plate 212 and the supporting chassis 213. The positioning pins 216 extend downward and penetrate the linkage support plate 212. The number of elastic members 217 is equal to the number of positioning pins 216, and the elastic members 217 are correspondingly sleeved on the positioning pins 216, and the two ends thereof abut against the linkage support plate 212 and the supporting chassis 213. Among them, the elastic member 217 can be a spring that is coaxially sleeved with the positioning pin 216 and mainly bears pressure. Although the linkage rod 214 can move upward when the first link 224 and the second link 225 are flush, and the clamping assembly 22 can re-clamp the quartz tube 3, resulting in the obstruction of the lifting process of the quartz tube 3, in this embodiment, since the supporting chassis 213 has no possibility of continuing to move upward after rising and resetting to the high point, when the quartz tube 3 is separated from the supporting chassis 213, the linkage rod 214 has no possibility of moving upward, and there is no such risk. This clamping control process based on the motion state of the clamped object is simple and effective.

[0045] In a further embodiment, Figure 6 As shown, the clamping assembly 22 also includes a clamping pad 229 detachably mounted on the clamping fixture 221 and the clamping portion 2221. The clamping pad 229 is usually made of a high temperature resistant material. At the same time, the setting of the clamping pad 229 can protect the clamping fixture 221 and the clamping closure member 222, reduce the damage, deformation and damage of the two when subjected to high temperature, and enable the clamping assembly 22 to maintain a good clamping effect for a long time.

[0046] Combination Figures 3 to 5In a further embodiment, the clamping mechanism 2 further includes a rotating assembly 23 and a limiting bracket 24. The rotating assembly 23 includes a seat bearing 231, a limiting rotating shaft 232 and a connecting bracket 233. The seat bearing 231 is fixedly mounted on the top of the mobile frame 12 of the mobile mechanism 1. Both ends of the limiting rotating shaft 232 axially pass through the connecting bracket 233 and are connected to the seat bearing 231. The limiting bracket 24 is fixedly connected to the bottom of the linkage bracket 211 and is fixed to a side away from the linkage support plate 212. The limiting bracket 24 extends laterally to the bottom of the mobile frame 12 in a direction perpendicular to the height of the linkage bracket 211. The limiting bracket 24 is rotationally limited by the mobile frame 12. That is, when the limit bracket 24 rotates with the limit rotating shaft 232 as the rotating shaft, it rotates to the horizontal state at the highest point. At this time, the limit bracket 24 is blocked by the bottom crossbeam of the movable frame 12, thereby preventing the quartz tube 3 clamped by the clamping assembly 22 from falling in the expansion direction of the clamping and closing member 222, thereby reducing the safety risk. Figure 8 As shown, the rotation adjustment of the clamping mechanism 2 is achieved by using the rotating assembly 23, so as to adjust the inclination angle of the quartz tube 3, so as to prevent the quartz tube 3 from escaping from the clamping mechanism 2 due to the huge inertia during the acceleration process and stagnation, thereby improving the safety and clamping stability. When there is no external force, the limit bracket 24 presses upward against the moving frame 12 to keep the linkage support plate 212 in a roughly horizontal position. When the quartz tube 3 is moved, a force is applied to the limit bracket 24 from top to bottom to make the linkage assembly 21 and the clamping assembly 22 rotate clockwise, so as to avoid acceleration / deceleration during the movement, and the emergency stop behavior causing the quartz tube 3 to tip over, thereby improving the safety of the transportation process. It should be noted that the rotation direction of the linkage assembly 21 and the clamping assembly 22 is based on the attached Figure 5 Provide explanation.

[0047] In addition, this embodiment provides a method for using the carrier for the quartz tube, including: When the quartz tube 3 is placed on the supporting chassis 213 from top to bottom, the supporting chassis 213 is pressed to move downward, so that the linkage rod 214 moves downward together with the supporting chassis 213, and drives the clamping and closing parts 222 of each clamping assembly 22 to close, so that the clamping space 223 between the clamping and closing parts 222 of each clamping assembly 22 and the clamping fixed part 221 is reduced, and the quartz tube 3 is clamped synchronously. When the linkage rod 214 moves downward, the end of the first link 224 hinged to the linkage rod 214 moves downward accordingly. The other end of the first link 224 moves toward the side close to the clamping support 226, and pushes the clamping movable seat 227 to move toward the side close to the clamping fixed part 221 through the second link 225. The clamping movable seat 227 pushes the clamping closing member 222 to gradually close through the third connecting rod 228, so that the clamping space 223 between the clamping closing member 222 and the clamping fixing member 221 is reduced, and the clamping closing member 222 and the clamping fixing member 221 fit and press the outer wall of the quartz tube 3, thereby gradually clamping the quartz tube 3.

[0048] When the quartz tube 3 is lifted from the support chassis 213 from bottom to top, the pressure on the support chassis 213 gradually decreases until it disappears, and the support chassis 213 moves upward to reset. The linkage rod 214 moves upward with the support chassis 213, and drives the clamping and closing parts 222 of each clamping assembly 22 to expand, so that the clamping space 223 between the clamping fixing part 221 and the clamping and closing part 222 of each clamping assembly 22 is expanded, and the clamping effect on the quartz tube 3 is released. When the linkage rod 214 moves upward, the end of the first link 224 hinged to the linkage rod 214 moves upward accordingly. The other end of the first link 224 moves to the side close to the clamping support 226, and is transmitted to the clamping support 226 through the second link 225. Since the second link 225 is slidably connected to the clamping support 226, the clamping movable seat 227 moves to the side away from the clamping fixing part 221. The clamping movable seat 227 pulls the clamping closing member 222 to expand gradually through the third connecting rod 228, so that the clamping space 223 between the clamping closing member 222 and the clamping fixing member 221 increases, and the clamping closing member 222 gradually moves away from the outer wall of the quartz tube 3, thereby gradually releasing the clamping of the quartz tube 3.

[0049] Compared with the prior art, the carrier for the quartz tube provided in this embodiment and the method for using the same can clamp the quartz tube 3 during the hoisting and placement process, thereby maintaining the stable state of the quartz tube 3 during the transportation of the quartz tube 3. During the falling process of the quartz tube 3, the self-locking of the clamping mechanism 2 is realized by the deadweight of the quartz tube 3, and the stable state of the clamping mechanism 2 is improved, and the greater the deadweight of the quartz tube 3, the tighter the clamping. That is, when the quartz tube 3 is loaded, the tighter the clamping, the more stable the quartz tube 3 is; and when there is no loading in the quartz tube 3, the clamping force is reduced to a certain extent. Thus, different clamping forces can be achieved according to the loading state of the quartz tube 3 while maintaining the clamping stability. Avoid the situation where the same clamping force causes poor clamping effect or excessive clamping force, and the service life is low. When unlocking, it is only necessary to lift the quartz tube 3 to complete the unlocking, the process is simple, the operation is convenient, and there is no need to set up an electric drive unit and an intelligent control unit for clamping control.

[0050] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
