[0002] The silicon core is a key component in the polycrystalline silicon production process. Its main function is to act as a reaction carrier in the polycrystalline silicon reduction furnace under high temperature and high pressure, so that the raw materials hydrogen (H2) and trichlorosilane (STC) can be continuously reduced and deposited on the surface of the silicon core to produce polycrystalline silicon rods.

[0003] The current method for preparing square silicon cores is to first use the Czochralski method to pull silicon rods with a diameter of 200-300mm and a length of 1.5-4m, and then use a cutting machine to cut them into square silicon cores of appropriate sizes (10×10mm, 15×15mm or 18×18mm). During the cutting process, a vertical cutting machine is required, and the process of installing the silicon rods onto the vertical cutting machine is called rod mounting.

[0004] However, in the traditional production of square silicon cores, the ingots are usually transported by crane. During the crane's transport, the ingots will shake, making it difficult to accurately place them into the vertical cutting machine. It requires the assistance of staff to adjust the position of the ingots. The loading process is cumbersome, has a low degree of automation, increases the labor intensity of the staff, and affects production efficiency. Moreover, the shaking of the ingots may also bring the risk of collision, which will affect the processing quality.
