Abstract

The invention discloses a quartz crucible heating, coating, and packaging integral machine. The machine comprises a quartz crucible conveying system. A heating system, a spray-coating system, and a packaging system are sequentially arranged on a conveying direction. The heating system comprises a sealable heating chamber. An infrared heating tube and a temperature sensor for keeping a constant temperature are arranged in the heating chamber. The spray-coating system comprises a sealable coating chamber. An automatic elevatable rotation joint and a nozzle are arranged in the coating chamber. The packaging system is composed of negative pressure adsorption manipulators provided above and beside the quartz crucible. The conveying system comprises a servo motor as a power source, a sprocket wheel, a chain, and a conveyor belt. The sprocket wheel and the chain are connected. The conveyor belt is arranged on the chain. With the machine provided by the invention, the quartz crucible can be effectively heated, coated, packaged, and stored, such that labor is greatly saved, working efficiency is improved, and a problem of quartz crucible coating powder poor bonding is effectively solved.

Description

technical field [0001] The invention relates to automatic coating and packaging equipment for quartz crucibles, in particular to an integrated machine for heating, coating and packaging quartz crucibles. Background technique [0002] As one of the causes of dislocations formed on the silicon single crystal when the silicon single crystal is drawn, cristobalite precipitated on the inner surface of the quartz crucible is released into the silicon melt. As a countermeasure, there are known methods of coating a crystallization accelerator on the inner surface of a crucible to form crystallization at an early stage on the inner surface of the crucible. In these methods, a barium hydroxide solution is coated on the surface of a quartz crucible, and barium hydroxide and The reaction of carbon dioxide in the air causes the formed barium carbonate to precipitate on the surface of the crucible, dry it, and then adhere to the surface of the crucible. However, the quartz crucible with t...
