The invention relates to the technical field of ultraviolet curing, and discloses an ultraviolet curing machine which comprises an ultraviolet light source, a mask plate and a bearing table. The mark plate is positioned on one side of a light emitting surface of the ultraviolet light source. The bearing plate is positioned on one side, far from the ultraviolet light source, of the mask plate. The bearing table is provided with counterpoint through holes and protective caps. The counterpoint through holes penetrate through the bearing table in the thickness direction and are used for counterpoint operation of a display panel. The protective caps are used for covering the counterpoint through holes. According to the ultraviolet curing machine, the counterpoint through holes are formed in the bearing table, the protective caps are used for covering the counterpoint through holes, and therefore, counterpoint operation between the display panel and the mask plate can be achieved, ultraviolet light can be prevented from being reflected to one side, facing the bearing table, of the display screen, the condition that an RGB chromatograph material of the display screen conducts a chemical reaction, resulting in generation of green blocks is avoided, and the display screen can be further prevented from becoming green.
