Specific implementation

[0030] ​The utility model is further described below in combination with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and can be implemented, but the embodiments are not as the limitation of the utility model. Embodiment 1:

[0031] Referring to Figures 1 to 5 Embodiment 1 of the utility model provides a kind of taking-out tool of crystal bar, including guide mechanism 10, lifting mechanism 20 and crystal support mechanism 30.

[0032] Wherein, guide mechanism 10 includes guide bracket 11, two mobile brackets 12 movably installed in guide bracket 11, and multiple first roller 13 oppositely arranged on two mobile brackets 12.The aforementioned two mobile brackets 12 are symmetrically arranged along the first direction, and can be close to or away from each other along the first direction.In the embodiment, the first direction is the length direction of guide bracket 11.For Figure 1 The first direction can be understood as horizontal direction in the view angle in the above figure.

[0033] Lifting mechanism 20 includes lifting fixed bracket 21 arranged between two mobile brackets 12, first lifting bracket 22 installed in the inner side of lifting fixed bracket 21, and second lifting bracket 23 arranged between first lifting bracket 22 and can be lifted along the second direction. Wherein, lifting fixed bracket 21 is fixedly installed in guide bracket 11.The aforementioned second direction is perpendicular to the first direction, so that Figure 1 The second direction is vertical direction in the view angle in the above figure. Therefore, second lifting bracket 23 is lifted along the vertical direction;

[0034] Crystal support mechanism 30 is installed in second lifting bracket 23.Crystal support mechanism 30 is used to support crystal bar.

[0035] The working principle of the taking-out tool of crystal bar is as follows: before taking crystal bar, first drive crystal support mechanism 30 to descend along the vertical direction (second direction) by second lifting bracket 23, and place crystal support mechanism 30 to pit / negative one floor.Crystal bar is taken out, and the bottom end of the crystal bar is accurately connected with the crystal support mechanism 30 by using two mobile brackets 12 and multiple first rollers 13 oppositely arranged on the brackets, so that the crystal bar is preliminarily limited and guided in the circumferential direction, to prevent the crystal bar from being damaged by knocking. After the crystal bar is completely taken out, drive crystal support mechanism 30 to ascend by second lifting bracket 23, so that the middle position of the crystal bar supported by crystal support mechanism 30 is equivalent to the height of mobile bracket 12, and then the crystal bar is clamped by first roller through the opposite movement of mobile bracket 12. Through the above scheme, in the process of placing crystal support mechanism 30 by descending the crystal bar, the shaking, collision or unstable support of the crystal bar is effectively alleviated, so that the production quality and efficiency of single crystal silicon rod are improved, and the production cost of enterprise is reduced.

[0036] Referring to Figures 3 to 4 As shown in the drawings, the crystal bar taking-out tool of the utility model, in some embodiments, the top end of the second lifting support 23 is provided with the second roller support 24. The second roller support 24 is provided with the second roller 241 which rotates. The second roller 241 is used to provide the crystal bar with circumferential guiding support.

[0037] Specifically, in the process of the crystal bar descending, the second roller 241 at the top end of the second lifting support 23 is used to preliminarily guide the crystal bar, so that the bottom end of the crystal bar can be limited between the two guiding supports and further limited and guided by the first roller 13 on the two guiding supports. Thus, the second roller 241 cooperates with the first roller 13 to provide the crystal bar with additional circumferential guiding support, further reduces the shaking and deviation of the crystal bar in the process of descending due to collision or unstable factors, thereby enhancing the stability of the crystal bar, reducing the risk of damage, and ensuring that the crystal bar can be safely and accurately taken out from the furnace chamber and lowered into the pit.

[0038] Referring to Figures 3 to 4 As shown in the drawings, the crystal bar taking-out tool of the utility model, in some embodiments, the second roller support 24 is provided with a plurality of second rollers 241 which rotate. The plurality of second rollers 241 enclose a space for semi-surrounding the crystal bar. By providing a plurality of second rollers 241 which rotate on the second roller support 24, these rollers enclose a space for semi-surrounding the crystal bar, thereby providing the crystal bar with more comprehensive guiding and support and enhancing the stability of the crystal bar in the process of descending.

[0039] Specifically, the second roller support 24 is provided with three second rollers 241 which rotate, and the three second rollers 241 are symmetrically arranged around the crystal bar. Two of the second rollers 241 are located on both sides of the crystal bar and are distributed in a V shape, and the third second roller 241 is located between the two rollers. The three second rollers 241 jointly constitute a three-point support structure. Such a layout ensures that the crystal bar is evenly limited and guided in the process of lifting and descending, effectively avoiding damage caused by uneven stress.

[0040] Referring to Figure 2 As shown in the drawings, the crystal bar taking-out tool of the utility model, in some embodiments, the moving support 12 is provided with the roller mounting support 14. The roller mounting support 14 has a first mounting surface 141 and a second mounting surface 142. The first mounting surface 141 and the second mounting surface 142 are connected to form a V-shaped mounting surface. The first mounting surface 141 and the second mounting surface 142 are respectively provided with two first rollers 13 which are arranged in an up-down manner.

[0041] The first mounting surface 141 and the second mounting surface 142 are connected to each other, and form a V-shaped mounting surface. The four first rollers 13 mounted on the V-shaped mounting surface can provide a V-shaped circumferential supporting surface. The V-shaped supporting design can closely fit the side surface of the crystal bar, and can guide and position the crystal bar during lifting, and can stably clamp the crystal bar during carrying, and can reduce the rolling or deviation of the crystal bar during carrying.

[0042] Referring to Figure 2 As shown in the drawings, the crystal bar taking-out tool of the utility model, in some embodiments, the guide mechanism 10 further includes a guide driving assembly for driving the two moving brackets 12 to move close to or away from each other.

Among them, the guide screw rod 17 and the guide guide rod 18 are arranged in parallel, and the guide screw rod 17 and the guide guide rod 18 are arranged on the guide bracket 11 along the length direction of the guide bracket 11. The length direction of the guide bracket 11 is the first direction. Two guide guide rods 18 are symmetrically arranged on both sides of the axial direction of the guide screw rod 17. The guide screw rod 17 is rotationally connected with the guide bracket 11. The guide motor 15 is connected with the guide speed reducer 16. The guide speed reducer 16 is installed at one end of the guide bracket 11. And one end of the guide screw rod 17 extends out of the guide bracket 11 and is connected with the output end of the guide speed reducer 16. In addition, the axial both ends of the guide screw rod 17 are respectively provided with a forward thread and a reverse thread towards the middle. The two moving brackets 12 are threadedly connected with the forward thread and the reverse thread respectively, and the two moving brackets 12 are slidingly arranged on the guide guide rod 18.

[0043] When the guide motor 15 is started, it drives the guide screw rod 17 to rotate through the speed reduction effect of the guide speed reducer 16. The guide screw rod 17 is provided with a forward thread and a reverse thread at both ends, so that the two moving brackets 12 connected therewith can move close to or away from each other along the extension direction of the guide guide rod 18, thereby adjusting the distance between the two moving brackets 12, and realizing the guiding, clamping and releasing of the crystal bar. When the two moving brackets 12 move close to each other and contact the crystal bar, they work cooperatively to guide and support the crystal bar to keep stable during lifting. On the contrary, when it is needed to remove the crystal bar from the tool, the two moving brackets 12 move away from each other to facilitate the placement of the crystal bar.

[0044] Referring to Figure 2 As shown in the drawings, the crystal bar taking-out tool of the utility model, in some embodiments, the lifting mechanism 20 further includes a first lifting guide wheel 25 installed on the inner side of the first lifting bracket 22. At the same time, the side surface of the second lifting bracket 23 opposite to the first lifting bracket 22 is provided with a first guide groove 231. The first lifting guide wheel 25 is rollingly matched with the first guide groove 231.

[0045] The first lifting guide wheel 25 is in rolling fit with the first guide groove 231, so that the second lifting support 23 can be smoothly guided during lifting, and the stability and reliability of the lifting mechanism are ensured, and damage of the crystal bar caused by instability during lifting can be effectively avoided.

[0046] Referring to Figure 2 As shown in the drawings, in some embodiments, the lifting mechanism 20 further comprises a first lifting driving assembly for driving the second lifting support 23 to lift in the second direction. The first lifting driving assembly comprises a first mounting seat 26, a first lifting motor 27, a first lifting reducer 28, a lifting gear 29 and a lifting rack 291. The first mounting seat 26 is mounted on the guide support 11. The first lifting reducer 28 is mounted on the first mounting seat 26. The first lifting motor 27 is connected with the first lifting reducer 28, and the output end of the first lifting reducer 28 is connected with the lifting gear 29. The lifting rack 291 is mounted on the second lifting support 23 in the second direction and is in mesh with the lifting gear 29.

[0047] The first lifting motor 27 is connected with the first lifting reducer 28, and the rotating power of the motor is transmitted to the lifting gear 29 through the speed reduction effect of the reducer 28. The lifting gear 29 is in mesh with the lifting rack 291 mounted on the second lifting support 23. When the lifting gear 29 rotates, the lifting rack 291 is driven to move linearly along the vertical direction (the second direction) through the mesh transmission between the gear and the rack, and in turn drives the second lifting support 23 and the crystal holder mechanism carried thereby to ascend or descend along the vertical direction.

[0048] Referring to Figure 3 and Figure 5 As shown in the drawings, in some embodiments, the crystal holder mechanism 30 comprises a crystal holder base 31 and a second lifting driving assembly. The second lifting driving assembly is mounted on the second lifting support 23, and the second lifting driving assembly is connected with the crystal holder base 31 and is used to drive the crystal holder base 31 to move in the second direction.

[0049] The second lifting driving assembly drives the crystal holder base 31 to lift, so as to adjust the height of the crystal holder base 31. On the one hand, in the process of lowering the crystal bar, the crystal holder base 31 can be lifted to be docked with the bottom end of the crystal bar as soon as possible, so as to provide bottom support for the crystal bar and avoid damage in the process of lowering the crystal bar. On the other hand, the crystal holder base 31 can also be kept at a proper distance from the guide mechanism 10, so that the middle position of the crystal bar supported by the crystal holder base 31 with a relatively short length can be clamped by the guide mechanism 10, so that the crystal bar can be stably clamped, and the stability of the process of lowering the crystal bar is ensured.

[0050] Referring to Figure 3 and Figure 5As shown, in some embodiments, the second lifting driving assembly includes a second mounting seat 32, a second lifting motor 33, a second speed reducer 34, and a lifting screw rod 35. The second mounting seat 32 is mounted on the second lifting support 23. The second speed reducer 34 is mounted on the second mounting seat 32. The second lifting motor 33 is connected with the second speed reducer 34. The lifting screw rod 35 is rotatably mounted in the middle of the second lifting support 23. Moreover, the second speed reducer 34 is connected with one end of the lifting screw rod 35. The other end of the lifting screw rod 35 is threadedly connected with the crystal holder base 31.

[0051] The rotating power of the second lifting motor 33 is transmitted to one end of the lifting screw rod 35 after being decelerated by the speed reducer 34, so that the screw rod moves along the axial direction. The other end of the lifting screw rod 35 is connected with the crystal holder base 31 through the thread, and the movement of the screw rod causes the crystal holder base 31 to rise or fall in the vertical direction, thereby realizing the precise lifting control of the crystal bar and ensuring the stability and safety of the crystal bar during the taking-out process.

[0052] Referring to Figure 3 and Figure 5 As shown, specifically, the crystal holder mechanism 30 further includes a guide assembly, which includes a second lifting guide wheel 36 mounted on the outer side of the crystal holder base 31, and the inner side of the second lifting support 23 is provided with a second guide groove 232 in rolling cooperation with the second lifting guide wheel 36.

[0053] The cooperation of the second lifting guide wheel 36 and the second guide groove 232 further ensures the stability and accuracy of the crystal holder base 31 during the rising or falling along the second lifting support 23, and reduces the shaking and damage risk of the crystal bar during the operation.

[0054] Referring to Figure 5 As shown, in some embodiments, the crystal holder base 31 includes a crystal holder support 311, a crystal holder bottom plate 312, a crystal holder back plate 313, a crystal holder side plate 314, and a crystal holder support ring 315.

Specifically, the second lifting guide wheel 36 is mounted on the outer side of the crystal holder support 311, so as to be in rolling cooperation with the second guide groove 232, thereby guiding the lifting movement of the crystal holder mechanism 30.

[0055] The crystal holder base 31 can form a stable accommodating cavity for safely accommodating the crystal rod through the fixed connection of the crystal holder support ring 311, the crystal holder bottom plate 312, the crystal holder back plate 313 and the crystal holder side plate 314. The crystal holder support ring 315 is arranged on the crystal holder bottom plate 312 through the elastic member 316, so that the crystal holder support ring 315 can float within a certain range, thereby providing support and buffering for the crystal rod and reducing the vibration and impact of the crystal rod during the taking out and carrying process.

[0056] Referring to Figure 5 Further, the crystal holder base 31 further comprises a protection block 317 arranged on the inner side of the crystal holder side plate 314. The protection block 317 can protect the crystal rod placed in the aforementioned accommodating cavity from being abraded.
