Quartz boat clamping tooth fragment cleaning device

Abstract

The invention provides a quartz boat clamping tooth fragment cleaning device. The quartz boat clamping tooth fragment cleaning device comprises a suction pipe body, and is characterized in that the suction pipe body comprises a suction nozzle pipe and a negative pressure pipe; the suction nozzle pipe and the negative pressure pipe are in threaded connection into a whole; one end of the suction nozzle pipe is provided with a duckbilled suction head; and the negative pressure pipe is externally connected with a negative pressure switching connector. When the cleaning device is in use, one end ofthe negative pressure pipe is externally provided with a negative pressure connector connected with negative pressure. A worker takes up the suction pipe body and presses an air hole with a finger, the duckbilled suction head generates negative pressure and then is placed into a fragment box, the worker loosens the air hole, and then fragments attached to quartz boat clamping teeth can be suckedeasily. The quartz boat clamping tooth fragment cleaning device has no influence on intact silicon wafers around through inward suction and is convenient to use and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of solar energy production, and in particular relates to a device for cleaning debris of quartz boat teeth. Background technique [0002] Solar cells are important components in solar photovoltaic power generation systems, and monocrystalline silicon solar cells are currently the fastest growing type of solar cells. With the rapid development of the solar photovoltaic industry, it is necessary to continuously reduce the cost of materials and production costs while improving the conversion efficiency and power generation of solar cells. [0003] In order to improve the qualification rate of solar cells and reduce production costs, it is particularly important to improve the defects in the tooling process of existing equipment. In the production process of silicon wafer solar cells, the key processes of diffusion and thermal oxidation, in which both diffusion and thermal oxidation processes need to insert sil...

AI Technical Summary

Problems solved by technology

In the production process of silicon wafer solar cells, the key process flow of diffusion and thermal oxidation, in which the diffusion and thermal oxidation processes need to insert silicon wafer solar cells into the quartz boat, but there will be debris problems in the process

The jaws of the quartz boat are covered with small debris. At present, most of the existing technologies choose to use an air gun to clean the debris or use a thin caliper to clean the debris. However, the air gun blowing process will blow the debris to other silicon wafers or into the air, resulting in silicon wafers being damaged. Dirty, EL black spots on finished cells degrade, resulting in huge cost losses. In addition, the cleaning of thin and thin calipers is often not cleaned thoroughly, which may easily lead to subsequent silicon wafer dirt and chipping.
