Monocrystalline silicon wafer texturing device

Abstract

The utility model relates to the technical field of monocrystalline silicon wafer texturing, in particular to a monocrystalline silicon wafer texturing device. The texturing device comprises a texturing box, a fixing assembly and a turn-over assembly, openings and conveying frames penetrating through the openings are arranged at the two ends of the texturing box, electric conveying belts used for conveying monocrystalline silicon wafers are arranged in the conveying frames in a transmission mode, the fixing assembly is movably arranged on the inner side of the texturing box and located between the two conveying frames, and the turn-over assembly is arranged on the outer side of the texturing box. And the turnover mechanism is used for turning over and transferring the fixed monocrystalline silicon wafer to the electric conveying belt on the other side. According to the utility model, the two groups of conveying frames, the fixing assembly and the turn-over assembly are arranged in the texturing box, and through the cooperation of the fixing assembly, the rotating shaft, the gear, the guide frame, the rack and the reciprocating mechanism, single-sided textured monocrystalline silicon wafers on the conveying frame on the left side can be clamped and turned over to the conveying frame on the other side, so that double-sided texturing of the monocrystalline silicon wafers is realized; and subsequent manual turn-over and box entering are not needed, so that the overall texturing efficiency is improved.
