Photovoltaic texturing device with drying function

Abstract

A photovoltaic texturing device with a drying function disclosed by the present invention comprises a texturing table, a splash-proof mechanism and a support frame, the upper surface of the texturing table is provided with a texturing groove, the bottom of the texturing groove is fixedly provided with a heating pipe, a motor is fixed at the bottom of the rear end of the texturing table, and the output end of the motor is connected with a rotating shaft. The supporting frame is fixed to the left and right ends of the top of the texturing table, and a top plate is fixed to the top of the supporting frame. The photovoltaic texturing device with the drying function is provided with a heating chamber and a filter screen, hot air is generated through a draught fan and a heating wire in the heating chamber, the hot air is blown out from the air blowing opening in the bottom of the top plate to blow and dry a silicon wafer, meanwhile the filter screen in the heating chamber can filter air, the problem that the drying quality is affected due to the fact that dust is attached to the surface of a silicon wafer when the silicon wafer is blown and dried is solved, meanwhile, the distance between a storage rack and an air blowing opening can be adjusted under stretching and retracting of an air cylinder, and therefore the drying effect is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic panel processing equipment, in particular to a photovoltaic texturing device with a drying function. Background technique [0002] The main material for the preparation of solar photovoltaic panels is mostly semiconductor silicon wafers, which are made through a series of processes such as texturing, diffusion, etching, cleaning the surface of silicon wafers, anti-reflective film coating, printing and sintering, etc. During the processing process, silicon wafers need to be The surface of the surface is etched into a uniform suede surface with acid to increase the absorption of sunlight, reduce reflection, and increase the area of ​​the PN junction, thereby improving the photoelectric conversion efficiency of the battery. This step is called texturing, and it is also the first step in the overall processing process. , the effect of silicon wafer texturing is related to the subsequent processin...
