Description

Technical Field

[0001] The present application relates to the technical field of quartz crucible processing, and in particular to a quartz crucible spraying device. Background Art

[0002] Quartz crucibles are mainly used for pulling single crystal silicon by the Czochralski method, that is, heating polycrystalline silicon at high temperature to melt it in the quartz crucible, and then using a crystal puller to grow single crystals by pulling. Since the pulling time of single crystals is long, the quartz crucible is usually subjected to long-term thermal stress and is prone to deformation, thus affecting the results of crystal pulling. In order to solve the problem of easy deformation of the crucible, a coating that promotes the formation of cristobalite is sprayed on the inner surface of the crucible. Since the melting point of cristobalite is 1720℃, which is much higher than the melting point of silicon melt 1420℃, when a layer of cristobalite coating is formed on the inner surface of the crucible, it can effectively improve the resistance of the quartz crucible to thermal deformation and increase the service life of the crucible.

[0003] After checking the announcement number: CN212383945U, a quartz crucible high-efficiency coating spraying device is disclosed. This technology discloses "including an outer chassis, the inner wall of the left side of the outer chassis is fixedly installed with a coating storage tank, and the inner bottom wall of the outer chassis is fixedly installed with a waste receiving bowl. The quartz crucible high-efficiency coating spraying device uses a pull handle to pull out the motor, and then fixes the quartz crucible inside the enclosing ring through a locking device, and then pushes the motor to the center of the outer chassis, and then under the action of the electric push rod, the quartz crucible is sleeved inside the nozzle, and then the coating inside the coating storage tank is released, etc. The technical scheme has the technical effect that its internal spraying method can fully coat the inner wall of the quartz crucible at one time";

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing quartz crucible spraying device does not have a mechanism for clamping and fixing the quartz crucible to be sprayed. Since the crucible needs to be picked up when spraying the quartz crucible in order to spray the crucible, the crucible is generally held manually by hand. The crucible is prone to move during the spraying process, which in turn affects the spraying effect of the crucible. The lack of a clamping mechanism makes it inconvenient to clamp the sprayed crucible well, which reduces the effect of the crucible spraying device. Secondly, the existing crucible spraying device does not have an adjustment component. Since when spraying the crucible, the position of the spray rod needs to be adjusted according to the actual crucible to be sprayed in order to better spray the crucible. The lack of an adjustment component makes it inconvenient to quickly adjust the horizontal position of the spray rod, which reduces the convenience of using the crucible spraying device.
