Technical Field

[0002] Silicon rod processing mainly includes the following steps: Raw material refining: The first step in manufacturing silicon rods is to convert natural quartz sand into high-purity polycrystalline silicon. This process usually converts quartz sand into smelted silicon at high temperature by reacting it with a reducing agent, and then improves the purity through metallurgical purification methods. Silicon single crystal growth: The most commonly used method for silicon single crystal growth is the Czochralski process. In this process, the purified polycrystalline silicon is melted, and a fine single crystal silicon seed rod is inserted into the molten silicon, and then slowly rotated and pulled up under precisely controlled temperature conditions, so that the molten silicon crystallizes and grows along the seed rod to form a single crystal silicon rod.

However, it is inconvenient to protect the debris generated during the polishing of the silicon rods, which causes the debris to splash and cause injuries to the user, which is extremely inconvenient. Therefore, a polishing device for silicon rod processing with a protective structure is urgently needed to solve the above problem. Utility Model Content
