[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-3 As shown in the figure, an alkaline polishing and rework wafer storage device for solar cell processing according to one embodiment of the present invention includes a storage platform 1, on which a plurality of storage slots 102 are provided, that is, at least two storage slots 102 are provided. A sliding plate 3 matching the storage slot 102 is slidably connected to the storage platform 1. The solar cell storage box is not shown in the figure and is placed on the sliding plate 3. A baffle 4 is also fixedly connected to one end of the sliding plate 3, and a second handle 402 is fixedly connected to the baffle 4. The second handle 402 allows the sliding plate 3 to be easily pushed to move, and when the sliding plate 3 is completely located in the storage slot 102, the baffle 4 can completely block the storage slot 102 to cut off the communication between the outside world and the storage slot 102.

[0030] In other words, the outer diameter of the baffle 4 must be larger than the outer diameter of the receiving groove 102 to achieve the separation of the receiving groove 102 from the outside world. In this state, it largely ensures that solar cells that are not from the current batch are not easily contaminated by the outside world during the rework process, and provides a certain degree of protection for the solar cells that have already been reworked.

[0031] Specifically, such as Figure 2As shown, T-shaped limiting members 301 are fixedly connected to the two side walls of the slide plate 3 parallel to the sliding direction, and T-shaped grooves 1021 matching the T-shaped limiting members 301 are opened on the side wall of the storage groove 102. The slide plate 3 is slidably connected in the storage groove 102 through the cooperation of the T-shaped limiting members 301 and the T-shaped grooves 1021. When the slide plate 3 is in the semi-slid-out state, the T-shaped limiting members 301 can withstand the gravity and should ensure that the slide plate 3 does not deform, so as to support the slide plate 3.

[0032] like Figures 1-2 As shown, a label 17 is detachably installed on the baffle 4. The label 17 is used to record the solar cells stored in the solar cell storage box on the current skateboard 3. The label 17 can be used to find out the batch number and model information of the solar cells on the current skateboard 3.

[0033] Specifically, the baffle 4 has an insertion hole 401, and the label 17 is fixedly connected to a protrusion 1701 that matches the insertion hole 401. The insertion hole 401 and the protrusion 1701 are interference fit. The label 17 is fixed by inserting the protrusion 1701 into the insertion hole 401. Of course, the label 17 can also be detachably installed on the baffle 4 using other installation methods such as magnetic, snap-on, or Velcro.

[0034] like Figure 1 As shown, a placement box 18 is fixedly connected to one side of the storage platform 1, forming a groove for storing labels 17 between the placement box 18 and the storage platform 1. This groove can hold multiple labels 17 at the same time, and commonly used solar cell labels 17 can be placed in this groove for easy replacement of the labels 17.

[0035] like Figures 1-2 As shown, a U-shaped groove 101 is formed on the upper surface of the storage platform 1, and a first handle 2 that matches the U-shaped groove 101 is installed on the storage platform 1. The first handle 2 is rotatably connected to the upper end of the storage platform 1, and the storage platform 1 can be easily picked up through the first handle 2. In other words, the storage boxes on the skateboards 3 can be picked up and put down individually, or all the skateboards 3 in the storage platform 1 can be picked up and put down.

[0036] To ensure the stability of the storage box when placed on skateboard 3, such as Figures 2-7 As shown, the skateboard 3 is equipped with a first limiting component 5 and a second limiting component 13. The first limiting component 5 and the second limiting component 13 are vertically arranged, corresponding to the length and width of the storage box, respectively. A placement space is formed between the first limiting component 5 and the second limiting component 13, and the storage box is placed in the placement space. The first limiting component 5 and the second limiting component 13 can adjust the size of the placement space to match storage boxes of different sizes.

[0037] Specifically, such as Figures 2-6As shown, the first limiting component 5 includes a first bidirectional screw 6, and a second groove 303 matching the first bidirectional screw 6 is provided on the slide plate 3. A first helical gear 7 is fixedly connected to the middle of the first bidirectional screw 6. The first limiting component 5 also includes a second helical gear 8 meshing with the first helical gear 7. A connecting rod 9 is fixedly connected to the second helical gear 8, and a knob 10 is fixedly connected to the end of the connecting rod 9 away from the second helical gear 8. The knob 10 is rotatably connected to the slide plate 3. The knob 10 is located below the slide plate 3, and a groove 1022 matching the knob 10 is provided on the bottom wall of the storage groove 102.

[0038] In other words, by turning the knob 10, the connecting rod 9 can be rotated, which in turn drives the second helical gear 8 to rotate. The second helical gear 8 meshes with the first helical gear 7, which in turn drives the first bidirectional screw 6 to rotate, thus realizing the transmission of power.

[0039] like Figures 2-6 As shown, the first limiting component 5 also includes two first limiting plates 11, each with a first threaded hole 1101. The two first limiting plates 11 are located at both ends of the first bidirectional screw 6, and the first limiting plates 11 are slidably connected to the second sliding groove 303. The first limiting plates 11 are threadedly connected to the first bidirectional screw 6 through the first threaded hole 1101. The two ends of the first bidirectional screw 6 are fixedly connected to first bearings 12 that match the slide plate 3. That is, during the rotation of the first bidirectional screw 6, it can slide the first limiting plates 11 in the T-shaped limiting component 301, thereby changing the distance between the two first limiting plates 11, allowing storage boxes of different sizes to be held between the two first limiting plates 11, so as to ensure the stability of the storage boxes placed on the slide plate 3.

[0040] like Figure 2 , Figure 3 Combination Figure 7 As shown, the second limiting assembly 13 includes a second bidirectional screw 14. A first groove 302 matching the second bidirectional screw 14 is provided on the slide plate 3. The first groove 302 and the second groove 303 are perpendicular to each other. A second bearing 15 matching the slide plate 3 is fixedly connected to the middle of the second bidirectional screw 14. One end of the second bidirectional screw 14 protrudes from the slide plate 3; this end is the first end of the second bidirectional screw 14. The second limiting assembly 13 also includes two second limiting plates 16, located at both ends of the second bidirectional screw 14. The second limiting plates 16 are slidably connected within the first groove 302. A second threaded hole 1601 is provided on the second limiting plate 16, and the second limiting plate 16 is threadedly connected to the second bidirectional screw 14 through the second threaded hole 1601.

[0041] Similarly, by rotating the first end of the second bidirectional screw 14, the distance between the two second limiting plates 16 can be changed, allowing storage boxes of different sizes to be secured between the two second limiting plates 16. That is, by changing the distance between the second limiting plates 16, the second limiting plates 16 can be adapted to the length of the storage box, and by changing the distance between the first limiting plates 11, the first limiting plates 11 can be adapted to the width of the storage box. The changes in length and width allow the skateboard 3 to accommodate storage boxes of different sizes, making it convenient to place storage boxes of different sizes and ensuring the stability of the storage boxes on the skateboard 3 as much as possible.

[0042] When in use, the storage device uses the first limiting component 5 and the second limiting component 13 to change the distance between the first limiting plate 11 and the second limiting plate 16, allowing the inner walls of the first limiting plate 11 and the second limiting plate 16 to contact the outer wall of the storage box, thus securing the storage box. The storage box is then placed on the slide plate 3. When storing multiple batches of solar cells, multiple storage boxes can be placed on different slide plates 3, labeled with labels 17. Solar cells are then placed into the corresponding storage boxes on different slide plates 3 according to their labels, achieving categorized placement of the solar cells.

[0043] When not in use, the storage box is pushed into the storage slot 102 by the second handle 402. The storage box is completely inside the storage platform 1 and is protected to a certain extent, so as to avoid external factors from contaminating the solar cells.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
