Description

Technical Field

[0001] This utility model relates to the technical field of silicon core cleaning equipment, and in particular to a silicon core cleaning carrier. Background Technology

[0002] The production process of polycrystalline silicon is complex and involves many steps, especially in the polycrystalline silicon reduction and generation stage. The silicon core serves as the substrate for the deposition process, providing the foundation for silicon material deposition. During chemical vapor deposition, the surface of the silicon core provides a site for silicon atoms to be deposited. Its surface characteristics, such as cleanliness and roughness, affect the deposition rate and the quality of the silicon material. The etching treatment of the silicon core surface is crucial for the smooth growth of polycrystalline silicon. By removing impurities, oil stains, and oxides from the surface, the cleanliness and smoothness of the surface are ensured, providing ideal conditions for the uniform growth of polycrystalline silicon.

[0003] Currently, silicon core cleaning can be done manually or automatically. Manual cleaning has drawbacks such as strong acid corrosion, high labor intensity, and poor cleaning quality. With the widespread use of automatic cleaning equipment, the output and quality of cleaning have become more suitable for the needs of polysilicon production. However, the cleaning efficiency of the cleaning equipment is mainly affected by factors such as equipment size, cleaning tank structure, and cleaning carrier. Among these, the design of the cleaning carrier directly affects the cleaning efficiency and has a significant impact on the production capacity of the cleaning equipment.

[0004] Existing silicon core carrier designs are complex and heavy. After cleaning, the carrier without silicon cores needs to be transferred from the unloading platform to the loading platform. This transfer is done manually, which is labor-intensive. Furthermore, silicon core specifications are constantly changing. Polysilicon manufacturers typically use cuboid and cylindrical silicon cores. Existing cleaning carriers are usually designed to clean only square silicon cores. When using this carrier to clean round silicon cores, there are many contact points between the silicon core and the carrier's edges, resulting in high abnormal losses during the cleaning process and increasing cleaning costs.

With constant evolution, polysilicon manufacturers typically use two types of silicon cores: cuboid and cylindrical.

The driving device drives the spindle body 11 to rotate through the fixed plate components. Simultaneously, multiple support plates 221 form a circular structure, which is mounted on the spindle body 11. The axis of the circular structure coincides with the axis of the spindle body 11. Each support plate 221 has multiple placement slots 225 on its outer surface for placing silicon cores. The pressure plate 222 has mounting screw holes 223 at both ends. The first connecting component 224 is connected to the pressure plate 222 and the support plate 221. The inner side of the pressure plate 222 is attached to the outer side of the support plate 221, so that multiple silicon cores are fixed on multiple support components 22. The pressure plate 222 and the support plate 221 restrict the radial direction of the silicon cores. The limiting component 21 is set inside the first fixing plate 121 and the second fixing plate 122. The limiting component 21 restricts the axial direction of the silicon cores.

At the same time, different shaped placement slots 225 can be made as needed to place silicon cores of different shapes, thereby achieving the technical effect of improving the adaptability of the carrier.

[0031] The spindle assembly described above serves to support the mounting components. The spindle assembly includes a spindle body 11 and a fixing plate assembly. The fixing plate assembly includes a first fixing plate 121 and a second fixing plate 122, which are fixedly connected to both ends of the spindle body 11. The length of the spindle body 11 is determined by the size of the cleaning tank used with the equipment. An aluminum alloy frame is used in the middle of the spindle body 11, and the outside of the spindle body 11 is lined with plastic to prevent corrosion of the central aluminum alloy frame during medium-intensity pickling. The first fixing plate 121 and the second fixing plate 122 are installed at both ends of the spindle body 11 to connect to a drive device. The drive device drives either the first fixing plate 121 or the second fixing plate 122 to rotate, simultaneously causing the spindle body 11 to rotate around its axis.

There are at least three support components 22, which are mounted vertically and radially on the spindle body 11. Each support component 22 includes at least three support plates 221 arranged in a ring to form a circular or annular structure. The support plates 221 are made of nylon, and the number of support plates 221 is the same as the number of pressure plates 222. Multiple placement slots 225 are provided on the outer side of the support plate 221. Figure 3 and Figure 7As shown, the cross-sectional shape of the placement groove 225 is rectangular or semi-circular, or the shape of the placement groove 225 can be set as needed. The silicon core can be placed into the placement groove 225. Then, the pressure plate 222 is placed on the outer side of the support plate 221, with the inner side of the pressure plate 222 fitting against the outer side of the support plate 221. This clamps the silicon core between the pressure plate 222 and the support plate 221, keeping the silicon core within the placement groove 225 and reducing radial movement of the silicon core during the cleaning process. A 2-meter gap is left between the silicon core and the pressure plate 222 and support plate 221. A gap of mm is provided to accommodate the cleaning of silicon cores with large coaxiality errors. The pressure plate 222 is made of nylon, and mounting screw holes 223 are provided at both ends of the pressure plate 222.

The first connecting component 224 is a connecting bolt, which fixes the pressure plate 222 to the support plate 221, thereby facilitating the fixing and disassembly of the pressure plate 222. In this technical solution, the spindle body 11 is installed on the cleaning device. The spindle body 11 is equipped with fixing plate components at both ends. The drive device drives the spindle body 11 to rotate through the fixing plate components. Simultaneously, multiple support plates 221 form a circular structure, which is mounted on the spindle body 11. The axis of the circular structure coincides with the axis of the spindle body 11. Each support plate 221 has multiple slots 225 on its outer surface for inserting silicon cores. Each pressure plate 222 has mounting screw holes 223 at both ends. The first connecting component 224 connects the pressure plate 222 and the support plate 221. The inner side of the 2 is attached to the outer side of the support plate 221, so that multiple silicon cores are fixed on multiple support components 22. The pressure plate 222 and the support plate 221 restrict the radial direction of the silicon cores. The limiting component 21 is set inside the first fixing plate 121 and the second fixing plate 122. The limiting component 21 restricts the axial direction of the silicon cores. This not only facilitates the installation and disassembly of the silicon cores, but also facilitates the maintenance and repair of the carrier. At the same time, different shaped placement slots 225 can be made as needed to place silicon cores of different shapes, thereby achieving the technical effect of improving the adaptability of the carrier.
