[0032] As Figures 1 to 3As shown in the figure, the embodiment provides a single crystal silicon rod transfer device for adjusting the single crystal silicon rod 100 from a vertical state to a horizontal state for subsequent processing of the single crystal silicon rod 100. The single crystal silicon rod transfer device includes a frame 1, a pushing member 2 and a turnover protection member 3. The frame 1 includes a bearing plate 11 and two enclosures 12 arranged on both sides of the bearing plate 11 along the width direction. The pushing member 2 includes a main body 21 and an extension rod 22. The main body 21 can drive the extension rod 22 to extend and retract. The main body 21 is arranged at an angle with the bearing plate 11. The turnover protection member 3 includes a turnover plate 31 and a plurality of clamps 32. The turnover plate 31 is connected with the extension rod 22. The plurality of clamps 32 are arranged on the turnover plate 31 along the length direction of the turnover plate 31 and are used to fix the single crystal silicon rod 100. The turnover plate 31 is provided with a supporting plate 33 for lifting the single crystal silicon rod 100. The side of the turnover plate 31 close to the supporting plate 33 is rotationally connected with the enclosure 12. When the extension rod 22 is completely extended from the main body 21, the turnover plate 31 is perpendicular to the frame 1. When the extension rod 22 is completely retracted into the main body 21, the turnover plate 31 is parallel to the bearing plate 11.
[0033] When the single crystal silicon rod 100 is lowered from the single crystal furnace, the pushing member 2 is adjusted so that the extension rod 22 is completely pushed out of the main body 21. The turnover plate 31 is adjusted to be perpendicular to the frame 1. The opening of the clamp 32 and the supporting plate 33 are towards the single crystal silicon rod 100. As the single crystal silicon rod 100 is gradually lowered vertically from the single crystal furnace, the single crystal silicon rod 100 will enter the clamp 32 and finally abut against the supporting plate 33. The supporting plate 33 lifts the single crystal silicon rod 100. The clamp 32 is adjusted to fix the single crystal silicon rod 100 on the turnover protection member 3. The pushing member 2 is adjusted so that the extension rod 22 is retracted. When the extension rod 22 is retracted into the main body 21, the turnover protection member 3 is rotated until the extension rod 22 is completely retracted into the main body 21. The turnover plate 31 is parallel to the bearing plate 11. The single crystal silicon rod 100 is adjusted from the vertical state to the horizontal state. The rotation state of the turnover protection member 3 relative to the frame 1 is adjusted by the pushing member 2. The turnover process of the turnover protection member 3 is relatively stable. The single crystal silicon rod 100 can be smoothly converted from the vertical state to the horizontal state. The plurality of clamps 32 fix the single crystal silicon rod 100 through multiple points. The risk of the single crystal silicon rod 100 falling off is reduced. Compared with the existing method of adjusting the single crystal silicon rod 100 by using a mechanical arm, the risk of the single crystal silicon rod 100 falling off is greatly reduced. The number of scrapped single crystal silicon rods 100 is reduced. The waste of resources is effectively reduced.
[0034] In the embodiment, the pushing member 2 is a telescopic pneumatic cylinder. The stroke of the telescopic pneumatic cylinder is 500 mm. The speed is 5 mm / s. The pushing force is 7000 N.
[0035] As shown in the figure, Figure 3 and Figure 4As shown in the middle of the figure, in this embodiment, the side of the supporting plate 33 used to support the single crystal silicon rod 100 is provided with a receiving groove, and the head of the single crystal silicon rod 100 is placed in the receiving groove. The two ends of the single crystal silicon rod 100 are tapered, and the tapered part is called a seed crystal tip. By providing the receiving groove, the seed crystal tip can be protected and damage to the seed crystal tip can be avoided. The shape of the receiving groove is consistent with the shape of the seed crystal tip, so that the receiving groove and the seed crystal tip are conformally fitted, further improving the protection effect of the seed crystal tip. Further, a reinforcing rib 34 is arranged between the supporting plate 33 and the turnover plate 31. The arrangement of the reinforcing rib 34 can improve the connection strength between the supporting plate 33 and the turnover plate 31, so that the supporting plate 33 can more stably support the single crystal silicon rod 100, reducing the risk of the single crystal silicon rod 100 falling.
[0036] In this embodiment, a plurality of roller supports 35 are arranged along the length direction of the turnover plate 31. The roller support 35 includes a fixed frame and two rollers. The fixed frame is placed along the width direction of the turnover plate 31, and the two rollers are respectively placed at the two ends of the fixed frame. After the worker controls the pusher 2 to adjust the single crystal silicon rod 100 from the vertical state to the horizontal state, the single crystal silicon rod 100 is placed on the plurality of roller supports 35, and the clamp 32 is adjusted to release the fixation of the single crystal silicon rod 100 and the turnover protection piece 3. Since there are a plurality of rollers below the single crystal silicon rod 100, the worker can easily push the single crystal silicon rod 100 through the rollers, so that the single crystal silicon rod 100 quickly enters the cutting process, without the worker having to move the single crystal silicon rod 100, reducing the difficulty of the worker's work. The plurality of roller supports 35 are arranged on the turnover plate 31 at intervals. When the single crystal silicon rod 100 is placed on the plurality of roller supports 35, the plurality of roller supports 35 are uniformly stressed, avoiding the problem that some roller supports 35 are easily damaged due to excessive stress, so that the service life of the plurality of roller supports 35 is guaranteed.
[0037] Exemplarily, the fence 12 is provided with a lug, the side of the turnover plate 31 opposite to the lug is provided with a positioning groove, and the lug and the positioning groove are connected through a pin shaft. In this way, the stability of the turnover protection piece 3 in rotation relative to the frame 1 can be further improved, so that the conversion process of the single crystal silicon rod 100 from the vertical state to the horizontal state is more stable, and the safety of the conversion process of the single crystal silicon rod 100 is improved.
[0038] Exemplarily, as shown in the figure, Figure 2 , Figure 3 and Figure 5As shown in the figure, the hoop 32 comprises a surrounding ring 321 and a locking piece 322, the surrounding ring 321 is used to surround the single crystal silicon rod 100, and the surrounding ring 321 is provided with a positioning hole, the locking piece 322 abuts against the single crystal silicon rod 100 after passing through the positioning hole, and the positioning hole is threadedly connected with the locking piece 322, so that the locking piece 322 can stably abut against the single crystal silicon rod 100. The surrounding ring 321 limits the shaking range of the single crystal silicon rod 100, avoids large-scale shaking of the single crystal silicon rod 100, and the locking piece 322 is threadedly connected with the positioning hole, so that the single crystal silicon rod 100 is fixed on the turnover protection piece 3 when the locking piece 322 abuts against the single crystal silicon rod 100. The threaded connection between the locking piece 322 and the positioning hole can ensure that the locking piece 322 stably abuts against the single crystal silicon rod 100, and reduce the risk of falling of the single crystal silicon rod 100. In the embodiment, the locking piece 322 can be selected as a bolt.
[0039] The surrounding ring 321 is detachably connected with the turnover plate 31, which can reduce the occupied space of the single crystal silicon rod transfer device when placed, and facilitate the storage of the single crystal silicon rod transfer device. On the other hand, the staff can adjust the size of the surrounding ring 321 according to the size of the single crystal silicon rod 100, improve the versatility of the single crystal silicon rod transfer device, and make the design of the single crystal silicon rod transfer device more reasonable. Further, the side of the locking piece 322 abutting against the single crystal silicon rod 100 is provided with silica gel, so as to avoid scratching the surface of the single crystal silicon rod 100 by the locking piece 322. Further, a tray is installed on the frame 1, and the staff can place the detached surrounding ring 321 and locking piece 322 on the tray after detaching the surrounding ring 321, so as to facilitate the storage of the hoop 32.
[0040] In the embodiment, the frame 1 comprises four wheels 4, and the four wheels 4 are respectively arranged at the four corners of the bearing plate 11. The wheels 4 facilitate the movement of the single crystal silicon rod transfer device, so that the single crystal silicon rod transfer device can be conveniently placed below the single crystal furnace to receive the single crystal silicon rod 100. The wheels 4 can be selectively locked, and the staff can lock the wheels 4 when the single crystal silicon rod 100 needs to be received, so as to avoid the single crystal silicon rod transfer device from being deviated when the single crystal silicon rod 100 enters the hoop 32, and affect the placement of the single crystal silicon rod 100. The wheel 4 with the locking function belongs to a conventional component in the mechanical field, and the specific structure and working principle of the wheel 4 can be referred to the prior art, which will not be described in detail here. The frame 1 is welded by stainless steel pipes with a thickness of 2 mm, so that the overall bearing capacity of the frame 1 is ensured.
[0041] Obviously, the above embodiments of the present application are merely exemplary and are not intended to limit the embodiments of the present application. Various obvious changes and modifications can be made by those skilled in the art without departing from the scope of the present application. It is not necessary to enumerate all the embodiments.
