The invention relates to the technical field of liquid crystal glass processing, and discloses a UV light shielding assembly. The UV light shielding assembly comprises a fixing plate. A layer of light reflection paper is attached to the upper portion of the fixing plate. A light shielding material is attached to the lower portion of the fixing plate. Anti-static oil paper is attached to the lower portion of the light shielding material. According to the UV light shielding assembly, the poor phenomenon generated by UV lamplight irradiation on a liquid crystal area during existing UV curing is improved, the error rate of manual operation is lowered, the light shielding assembly can be made to cover the liquid crystal area more accurately, the light shielding assembly is effectively prevented from being heated or deformed after the light reflection paper is attached, and the poor phenomenon generated by light leakage of the light shielding assembly is completely avoided.
