Description

Technical Field

[0001] The invention belongs to the field of photovoltaics and semiconductors, and in particular relates to a quartz crucible automatic feeding and shape and size controlled growth device. Background Art

[0002] Quartz crucible is a subdivided product of quartz glass products. It is made of high-purity quartz sand through mold shaping and high-temperature production using the arc method. It has the characteristics of high temperature resistance, long service life, and high purity. Quartz crucible is mainly used as an auxiliary consumable for the drawing of high-purity single crystal silicon rods for semiconductors. It is a key disposable consumable for containing molten silicon liquid during the drawing process of single crystal silicon rods. According to the downstream application scenarios of single crystal silicon rods, quartz crucibles can be divided into quartz crucibles for semiconductor single crystal silicon growth (semiconductor quartz crucibles and photovoltaic single crystal silicon growth quartz crucibles). In recent years, with the vigorous development of the photovoltaic and semiconductor industries, the demand for the output of quartz crucibles has also increased year by year, and at the same time, higher requirements are placed on the quality of quartz crucibles and their production processes.

[0003] The quartz crucible needs to be stacked with quartz sand of different qualities in each layer under high temperature. The quality of the added quartz sand also varies. The location and stacking method will also change due to the different shapes of the inner wall and bottom of the quartz crucible. Due to this complex process requirement, the existing quartz crucible production method on the market is generally purely manual.

[0004] Workers work continuously and with high concentration in a high-temperature environment to prevent processing errors, environmental impurities and other problems. For example, if impurities fall into the crucible during processing or the thickness is uneven during the stacking process, the entire quartz crucible will become scrapped. The current market price of quartz sand is expensive, and the scrap rate increases, which in turn increases the cost of the entire quartz crucible and cannot meet the market's positioning requirements for quartz crucibles.

[0005] How to automatically add quartz sand of different qualities according to preset amounts and ensure the cleanliness of the added materials during the quartz crucible manufacturing process is one of the important solutions to improve the automation level of the entire quartz crucible manufacturing process.
