Description

Technical Field

[0001] The utility model relates to the technical field of silicon core processing, in particular to a square silicon core bracket of an automatic cleaning machine. Background Art

[0002] In semiconductor, photovoltaic and other high-tech industries, silicon core is a key material, and its surface cleanliness and quality have a crucial impact on the performance of the final product. In order to remove impurities and contaminants on the surface of silicon core, chemical cleaning with acid is usually required. However, in traditional cleaning methods, silicon core is often placed directly on the bracket of the cleaning equipment, which leads to a large contact area between the silicon core and the bracket, which not only affects the uniform corrosion of the surface of the silicon core by the acid, but also may cause the silicon core to be scratched or damaged during the cleaning process. In order to solve the above problems, researchers have been exploring and improving the cleaning methods and equipment of silicon core. Among them, a common practice is to reduce the contact area between the silicon core and the bracket by changing the design of the bracket. For example, some brackets use a fixed tooth structure with an opening, so that the silicon core can be suspended in the opening. However, the opening angle of these fixed teeth is often large, usually around 90 degrees, which still limits the uniform corrosion effect of the acid on the surface of the silicon core. Therefore, it is necessary to further improve the design of the silicon core bracket to improve the efficiency and effect of silicon core cleaning. Specifically, it is necessary to design a new type of silicon core bracket, whose fixed teeth have an opening angle of less than 90 degrees, so as to better support the silicon core in the air and reduce the contact area between the silicon core and the bracket, so as to achieve uniform and thorough corrosion of the silicon core surface by acid liquid and more effectively remove surface impurities. This new type of silicon core bracket will help improve the efficiency and quality of silicon core cleaning and provide strong support for the development of high-tech industries such as semiconductors and photovoltaics. Utility Model Content

[0003] In order to solve the above problems, an embodiment of the utility model provides a square silicon core bracket for an automatic cleaning machine, which achieves the purpose of solving the problems raised in the background technology. The fixed tooth angle is less than 90°, so the silicon core can be supported in the air, reducing the contact between the silicon core and the bracket. The acid liquid corrodes the surface of the square silicon core more evenly and thoroughly, and the surface impurities are better removed.

[0004] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a square silicon core bracket of an automatic cleaning machine, comprising a bracket body, a toothed bracket is arranged on the bracket body, and a plurality of fixed teeth with openings facing upward are arranged on the toothed bracket at intervals along the length direction, and the openings of the fixed teeth are used to place the silicon core, and the opening angle of the fixed teeth is less than 90 degrees. The fixed tooth angle is less than 90°, so that the silicon core can be supported in mid-air, reducing the contact between the silicon core and the bracket, and the acid liquid can corrode the surface of the square silicon core more evenly and thoroughly, thereby better removing surface impurities.

[0005] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0006] Preferably, the opening angle of the fixed teeth of the toothed bracket is 60-80°.

[0007] Preferably, the opening angle of the fixed teeth of the toothed bracket is 74°.

[0008] Preferably, a plurality of the toothed brackets are stacked side by side, and the fixed teeth on two adjacent toothed brackets are staggered to ensure that each layer of silicon cores is staggered, and compressed air flows from the gaps between the upper silicon cores to above the middle silicon cores, and then flows from the gaps between the middle silicon cores to above the lower silicon cores, thereby drying the water on each layer of silicon cores.

[0009] Preferably, an inverted V-shaped notch is provided at the bottom of the toothed bracket corresponding to the position of the fixed tooth below, and the inverted V-shaped notch cooperates with the top of the silicon core for positioning.

[0010] Preferably, the fixed teeth on the toothed bracket are arranged asymmetrically, wherein the distance between the fixed teeth at one edge and the end face differs from that between the fixed teeth at the other edge and the end face by 1 / 2 of the silicon core edge width.

[0011] Preferably, a straight section is provided at the bottom of the opening of the fixed tooth.

[0012] Preferably, the toothed bracket includes a supporting portion, with clamping portions provided at both ends of the supporting portion, a clamping groove provided on the outer side of the clamping portion, and the fixed teeth are arranged above the supporting portion. This design makes the installation and disassembly of the bracket easier and improves the operating efficiency.

[0013] Preferably, the supporting portion, the clamping portion and the fixing teeth are an integrally formed PPN body. This material has good corrosion resistance and environmental protection and will not cause adverse effects on the silicon core or the environment.

[0014] The beneficial effects of the embodiments of the utility model are:

[0015] (1) Improving cleaning efficiency and silicon core protection function: Since the opening angle of the fixed teeth is less than 90 degrees, the silicon core is supported in the air, which reduces the contact area between the silicon core and the bracket. Therefore, when the acid acts on the surface of the silicon core, the corrosion is more uniform and thorough, thereby more effectively removing impurities on the surface of the silicon core; since the silicon core is supported in the air, the direct contact with the bracket is reduced, which helps to prevent the silicon core from being scratched or damaged during the cleaning process, thereby extending the service life of the silicon core; (2) Optimizing air flow: The toothed brackets are stacked side by side, and the fixed teeth on the two adjacent toothed brackets are staggered. This design allows compressed air to flow more effectively from the gaps between the upper silicon core to the top of the middle silicon core, and then from the gaps between the middle silicon core to the top of the lower silicon core. This air flow method can more effectively dry the moisture on each layer of silicon core and prevent residual moisture from causing adverse effects on the silicon core; (3) Improve space utilization: The fixed teeth on the toothed bracket are arranged asymmetrically. This design allows the silicon core to be placed in an offset manner, thereby improving space utilization and allowing more silicon cores to be cleaned in a limited space; this automatic cleaning machine square silicon core bracket achieves efficient, uniform and thorough silicon core cleaning through its unique design and material selection, while protecting the silicon core, improving space utilization, enhancing structural stability, and simplifying the installation and disassembly process, with significant beneficial effects.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] At present, the silicon core cleaning machine places the silicon core with its corners facing upwards on a toothed silicon core bracket in a long frame. The toothed bracket ensures that the silicon cores are arranged at a fixed spacing and can be stacked. The toothed bracket uses 90° teeth to facilitate the fixing of square silicon cores, and the bracket is designed to be symmetrical. When the silicon cores are arranged, the silicon cores in the upper and lower layers correspond to each other. In the cleaning of silicon cores, the following disadvantages occur: 1): The bracket teeth are 90°, which is consistent with the angle of the square silicon core and fits tightly. In the acid corrosion process, less acid enters the contact position between the bracket teeth and the silicon core, and the corrosion is lighter, resulting in inconsistent surface quality of the silicon core; 2): In the water cutting process, each layer of silicon cores corresponds to each other, and the top silicon core blocks the lower two layers of silicon cores, resulting in compressed air to dry the top layer, but the lower two layers are blocked by the upper layer, and the water cutting effect is poor, and water stains often remain after drying.

[0023] In view of the above situation, this application proposes the following implementation plan:

[0024] like Figure 1-4 As shown, a square silicon core bracket of an automatic cleaning machine comprises a bracket body 2, a toothed bracket is installed on the bracket body, a plurality of fixed teeth 3 with openings upward are installed on the toothed bracket 4 at intervals along the length direction, the opening 5 of the fixed teeth is used to place the silicon core 1, and the angle of the opening 5 of the fixed teeth is less than 90 degrees. The angle of the fixed teeth is less than 90°, so that the silicon core can be supported in the air, reducing the contact between the silicon core and the bracket, and the acid liquid corrodes the surface of the square silicon core more evenly and thoroughly, and the surface impurities are better removed; wherein a plurality of toothed brackets are installed side by side, and the fixed teeth on two adjacent toothed brackets are installed in a staggered manner to ensure that each layer of silicon cores is staggered, and compressed air flows from the gaps between the upper silicon cores to the top of the middle silicon cores, and then flows from the gaps between the middle silicon cores to the top of the lower silicon cores, thereby drying the water on each layer of silicon cores; wherein An inverted V-shaped notch 9 is provided at the bottom of the toothed bracket corresponding to the position of the fixed tooth below, and the inverted V-shaped notch 9 cooperates with the top of the silicon core for positioning so as to fix the position of the silicon core. The specific arrangement is that the fixed teeth on the toothed bracket are arranged asymmetrically, wherein the distance between the edge fixed teeth at one end and the end face is 1 / 2 of the width of the silicon core edge compared with the distance between the edge fixed teeth at the other end and the end face; wherein the toothed bracket includes a supporting portion, and a clamping portion 6 is installed at both ends of the supporting portion, and a clamping groove 7 is provided on the outer side of the clamping portion 6, and the fixed teeth are installed above the supporting portion. This design makes the installation and disassembly of the bracket easier and improves the operating efficiency; wherein the supporting portion, the clamping portion, and the fixed teeth are an integrally formed PPN body, and this material has good corrosion resistance and environmental protection, and will not cause adverse effects on the silicon core or the environment.

[0025] As a preferred angle range, the opening angle of the fixed teeth of the toothed bracket is 60-80° to ensure better space utilization. As the optimal selection, the opening angle of the fixed teeth of the toothed bracket is 74°, and a straight section 8 is installed at the bottom of the opening of the fixed teeth, which enhances the structural stability of the fixed teeth, making it difficult for the silicone core to fall off or shift during the cleaning process, and is convenient for diversion during blow-drying.

[0026] The above structural design can achieve: (1) improving the cleaning efficiency and silicon core protection function: since the opening angle of the fixed teeth is less than 90 degrees, the silicon core is supported in the air, which reduces the contact area between the silicon core and the bracket. Therefore, when the acid acts on the surface of the silicon core, the corrosion is more uniform and thorough, thereby more effectively removing impurities on the surface of the silicon core; since the silicon core is supported in the air, the direct contact with the bracket is reduced, which helps to prevent the silicon core from being scratched or damaged during the cleaning process, thereby extending the service life of the silicon core; (2) optimizing air flow: the toothed brackets are stacked side by side, and the fixed teeth on the two adjacent toothed brackets are staggered. This design allows the compressed air to flow more effectively from the gaps between the upper silicon core to the top of the middle silicon core, and then from the gaps between the middle silicon core to the top of the lower silicon core. This air flow method can more effectively dry the moisture on each layer of silicon core and prevent residual moisture from causing adverse effects on the silicon core; (3) Improve space utilization: The fixed teeth on the toothed bracket are arranged asymmetrically. This design allows the silicon core to be placed in an offset manner, thereby improving space utilization and allowing more silicon cores to be cleaned in a limited space; this automatic cleaning machine square silicon core bracket achieves efficient, uniform and thorough silicon core cleaning through its unique design and material selection, while protecting the silicon core, improving space utilization, enhancing structural stability, and simplifying the installation and disassembly process, with significant beneficial effects.
