[0001] This utility model belongs to the technical field of silicon wafer material box equipment, specifically relating to a battery silicon wafer anti-friction material box. Background Technology

[0002] With the nation's increasing emphasis on clean energy, the photovoltaic industry has developed rapidly. During transport, solar cell silicon wafers need to be placed in cassettes to prevent slippage and wear. Existing cassettes typically employ a fixed-size design, intended to accommodate standard-sized silicon wafers in mass production. However, in actual production, there are certain errors in wafer size. Some wafers are too large to fit into the cassette, while others are too small, leaving gaps between the wafer and the cassette wall after placement, preventing effective fixation. This leads to friction between the silicon wafer and the cassette, damaging the wafer.

[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a battery silicon wafer anti-friction material box.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0024] 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.

[0025] like Figures 1 to 4 As shown, a battery silicon wafer anti-friction material box according to one embodiment of the present invention includes a box wall 1 and a base plate 2. Multiple fixing blocks 12 are symmetrically bonded to the box wall 1, and a protective layer 121 is installed on the fixing blocks 12. The battery silicon wafer anti-friction material box is provided with an ejection assembly, which allows the protective layer 121 to move away from or closer to the fixing blocks 12.

[0026] Specifically, when the silicon wafers are placed into the anti-friction cassette, the protective layer 121 is in close contact with the fixing block 12. At this time, the distance between the protective layers 121 is greater than the size of the silicon wafer, allowing for normal placement of the silicon wafers into the anti-friction cassette. After a certain number of silicon wafers have been placed into the anti-friction cassette, the protective layer 121 is moved away from the fixing block 12 by ejecting the assembly, thereby clamping the silicon wafers in the anti-friction cassette. This avoids situations where silicon wafers are too large to fit into the anti-friction cassette due to manufacturing errors, and also prevents gaps between silicon wafers that are too small and the anti-friction cassette. Furthermore, by moving the protective layer 121 away from or close to the fixing block 12, the anti-friction cassette can be adapted to accommodate silicon wafers of different sizes.

[0027] Preferably, the protective layer 121 is a silicone rubber layer. Silicone rubber is a high-temperature resistant and corrosion-resistant elastic material with an ultra-low coefficient of friction and is also very soft. These physical properties not only allow for long-term use and reduce operating costs, but also reduce wear on the edges of the battery silicon wafer, providing excellent protection for the battery silicon wafer.

[0028] like Figure 3 and Figure 4 As shown, the ejector assembly includes a pair of connecting posts 1211, which are symmetrically bonded to the protective layer 121. A sliding block 1212 is integrally formed at the end of the connecting post 1211 away from the protective layer 121. The fixing block 12 is provided with two pairs of fixing plates 123. A groove matching the sliding block 1212 is formed between the pair of fixing plates 123. The sliding block 1212 is slidably connected in the groove.

[0029] Specifically, the sliding block 1212 can not only slide in the groove formed between a pair of fixed plates 123, but also has a sealed connection with the groove. When the sliding block 1212 slides away from the fixed block 12, the protective layer 121 also moves away from the fixed block 12. In this way, the distance between the symmetrical protective layers 121 will be reduced, thereby clamping the battery silicon wafer in the anti-friction material box.

[0030] In order to enable the sliding block 1212 to slide within the groove, as Figures 2 to 4 As shown, the fixing block 12 has a first groove 1201 that communicates with the slide groove, and an air inlet pipe 122 that communicates with the first groove 1201 is installed on the fixing block 12. An air nozzle 15 is installed on the box wall 1, and a connecting pipe 151 that communicates with multiple air inlet pipes 122 is installed on the air nozzle 15.

[0031] Specifically, air can be supplied into the first groove 1201 through the air nozzle 15. The increased air pressure in the first groove 1201 can push the sliding block 1212, causing the sliding block 1212 to slide away from the fixed block 12, thereby moving the protective layer 121 away from the fixed block 12.

[0032] It is worth noting that, in order to prevent the sliding block 1212 from sliding out of the groove, a limiting block 124 is integrally formed at one end of the fixing plate 123 near the protective layer 121. The limiting block 124 can limit the sliding block 1212.

[0033] like Figure 3 and Figure 4 As shown, the fixing block 12 is equipped with a sealing plate 125 to seal the first groove 1201. Specifically, the sealing plate 125 can seal the first groove 1201, preventing gas leakage from the first groove 1201 after the protective layer 121 moves away from the fixing block 12, thus preventing the protective layer 121 from clamping the battery silicon wafer. At the same time, the sealing plate 125 also reduces the volume of the first groove 1201, thereby reducing the amount of gas entering the first groove 1201. When gas is introduced into the first groove 1201, the gas pressure inside the first groove 1201 can increase in a short time, thereby shortening the time required to push the sliding block 1212.

[0034] Furthermore, the connecting pipe 151 is embedded in the base plate 2. This prevents the battery silicon wafers in the anti-friction material box from pressing against the connecting pipe 151, thus preventing gas from flowing from the air nozzle 15 into the first tank 1201.

[0035] Furthermore, a second groove 14 is provided on the box wall 1, and an air nozzle 15 is installed in the second groove 14. Specifically, the length of the air nozzle 15 is less than the groove depth of the second groove 14 to prevent external forces from hitting the air nozzle 15 during transportation and storage of the battery silicon wafer anti-friction box, which could cause damage to the air nozzle 15.

[0036] As shown in box wall 1, a matching insert 17 is fixedly connected to the lower plate of the base plate 2. When the battery silicon wafer anti-friction boxes are stored in the warehouse, the insert 17 is inserted into the second groove 14, so that the battery silicon wafer anti-friction boxes are stacked on top of each other, which can save storage space and keep the stacked battery silicon wafer anti-friction boxes stable.

[0037] In addition, a guide block 13 is integrally formed on the fixing block 12, and the cross-section of the guide block 13 is arc-shaped. Specifically, when a battery silicon wafer is placed into the anti-friction material box, the battery silicon wafer slides down on the guide block 13, and the guide block 13 can guide the battery silicon wafer so that the battery silicon wafer falls into the center of the anti-friction material box.

[0038] It is worth noting that if random sampling of battery silicon wafers is required, the silicon wafers need to be removed. To facilitate handling, for example... Figure 1 and Figure 2 As shown, an opening 11 is provided on the box wall 1, and a fourth groove 22 matching the opening 11 is provided on the bottom plate 2. When taking out the battery silicon wafer, the inspector can reach into the opening 11 to take out the battery silicon wafer.

[0039] Furthermore, the base plate 2 is integrally formed with several protrusions 21. The protrusions 21 can create a certain gap between the battery silicon wafer and the base plate 2, allowing the operator's hand to reach under the battery silicon wafer, making it convenient for the operator to pick up the battery silicon wafer stacked on the base plate 2.

[0040] Furthermore, the bump 21 is covered with an anti-slip layer 211. The elasticity of the anti-slip layer 211 allows for soft contact between the battery silicon wafer and the bump 21, preventing the bottom battery silicon wafer from being crushed.

[0041] In addition, a third groove 16 is provided on the box wall 1. The third groove 16 provided on the box wall 1 can reduce the overall weight of the battery silicon wafer anti-friction box, save production costs during production, and also facilitate stacking and storage.

[0042] To enhance the strength of the box wall 1, a reinforcing rib 161 is integrally formed inside the third groove 16.

[0043] In use, place the battery silicon wafer on the base plate 2, and then connect the air pump or other air source device in the factory to the air nozzle 15 to fill the air nozzle 15 with air. The gas flows from the air nozzle 15 into the first groove 1201 and pushes the sliding block 1212 outward, thereby moving the protective layer 121 away from the fixed block 12. The protective layer 121 can then clamp the battery silicon wafer on the base plate 2 to prevent slippage and friction during the transfer of the battery silicon wafer.

[0044] Compared with the prior art, the battery silicon wafer anti-friction box of this utility model can be applied to battery silicon wafers of different sizes, and can fix the battery silicon wafers in the box, which can solve the problem of battery silicon wafer wear to a certain extent.
