[0028] See the attached drawings Figure 2 and Figure 4 , further, the rotary driving device includes a servo motor 5, a planetary reducer 50 and a spur gear driver 51. The inner ring of the output end of the spur gear driver 51 is connected to the bottom of the central support shaft 2, and a slewing bearing 6 is further provided at the top of the second flange clamp 26.

[0029] See the attached drawings Figure 3 and Figure 4 , further, the guiding device includes an electric cylinder 7 installed in the inner cavity at the top of the central support shaft 2. A top plate 70 is provided at the output end of the electric cylinder 7, and a connecting plate 41 is provided at the middle position of the bottom surface of the guiding disc 4; two first guiding rods 71 are provided on both sides of the top plate 70, and first linear bearings 710 are provided on the first guiding rods 71; the first linear bearings 710 are installed in the inner ring of the slewing bearing 6; four second guiding rods 8 are provided between the guiding disc 4 and the upper fixing cylinder 20, and second linear bearings are installed on the second guiding rods 8.

[0030] See attached picture Figure 6 Furthermore, an oblique guide pad 30 is provided at the outer end of the notch 3.

[0031] See attached picture Figure 4 Furthermore, a base plate 210 is provided at the bottom of the lower fixed cylinder 21 , the outer ring of the spur gear driver 51 is mounted on the base plate 210 , and a rubber pad 211 is mounted above the base plate 210 .

[0032] See attached picture Figure 5 Furthermore, a sensing block 230 is installed on the second waist hole rod-taking disk 23, and a sensing switch 110 is provided on the rotating connecting plate 11; the sensing block 230 and the sensing switch 110 are electrically connected to the main control unit respectively.

[0033] Preferably, the guide plate 4, the first waist hole rod taking plate 22, the second waist hole rod taking plate 23 and the third waist hole rod taking plate 24 are all made of bakelite material.

[0034] The present invention reconstructs a conventional wafer retrieval vehicle, retaining the original main body and rotator 10, and assembling the retrieval rods onto the rotator 10. This replaces the tedious process of manually cutting and retrieval one by one, achieving a one-step process of retrieval. After the seed crystal is cut, the rods are retrieved. The spur gear drive 51 then rotates the retrieval rods, allowing the silicon cores to be removed from the notches 3 of the upper and lower fixed barrels 20, 21, and then roll onto the subsequent connecting transmission belt via the oblique guide pads 30.

[0035] In this embodiment, the main part of the crystal retrieval vehicle 1 and the rotating connecting plate 11 are fixed on the rotator 10, wherein the three waist hole rod retrieval plates are fixed on the first flange clamp 25 by bolts, and the first flange clamp 25 is clamped on the central support shaft 2 by bolts. The height position of each first flange clamp 25 can be adjusted, which is relatively flexible and also plays a supporting role.

[0036] Specifically, the upper and lower fixed cylinders 20 and 21 are connected to the rotating connecting plate 11. A guide plate 4 is mounted on the upper fixed cylinder 20. The guide plate 4 and the three rod removal holes are all made of bakelite, preventing contamination of the silicon rods. The guide plate 4 is equipped with multiple guide tubes 40, each of which is of a certain length to ensure that all silicon rods can enter the second and third rod removal holes 24 without excessive tilting and thus preventing smooth insertion. Furthermore, a soft rubber pad 211 of a certain thickness is mounted on the lower fixed cylinder to cushion the cut silicon rods.

[0037] Specifically, the rotary drive device is connected by a straight-tooth driver 51 through a central support shaft 2 and a slewing bearing 6; the three waist-hole rod-taking disks are driven to rotate by rotating the central support shaft 2, so that the silicon core can roll out from the notch 3 along the inclined guide pad 30 after the upper and lower fixed cylinders are controlled to lie down by the rotator on the crystal retrieval vehicle.

[0038] Specifically, the guiding device enables all the guiding tubes 40 mounted on the guiding disc 4 to retract during vertical rod taking (as shown in the Figure 4 state) through the electric cylinder 7 and the connecting plate 41, and extend during horizontal rod discharging; the guiding disc 4 and the upper fixing cylinder 20 are connected by four second guiding rods 8 and four second linear bearings. The telescopic movement of the electric cylinder 7 drives the telescopic movement of the guiding disc 4. At the same time, two first guiding rods 71 and two first linear bearings 710 are also arranged in the middle of the top plate 70 of the electric cylinder 7, making the rod taking device stronger after lying down.

[0039] Specifically, under the control of the electrical program, the servo motor 5 cooperates with the planetary reducer 50 to enable the inner ring of the spur gear driver 51 to rotate smoothly. The outer ring of the spur gear driver 51 is fixed on the substrate 210, and the lower fixing cylinder 21 is fixed on the substrate 210, so that the upper and lower fixing cylinders do not rotate; a slewing bearing 6 is installed at the upper end of the central support shaft 2. In this way, only the central support shaft 2 and the three waist-hole rod taking discs mounted on the central support shaft 2 can rotate by a corresponding angle through program control to realize the discharging of silicon rods one by one.

[0040] Preferably, the second waist-hole rod taking disc 23 is equipped with an induction block 230. Each time the second waist-hole rod taking disc 23 can trigger the induction switch 110 and return to the initial origin position.

[0041] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
