The invention provides an ultraviolet light shading structure in a composite film semi-curing process, which is used for enabling photosensitive resin to be semi-cured by irradiating a film coated with the photosensitive resin through an ultraviolet light source, and comprises a series of shading plates which are arranged between the ultraviolet light source and the film in a replaceable manner, the external dimensions of the series of light shielding plates are the same, a plurality of through holes are formed in the series of light shielding plates, and the proportion of the area of the through holes in the series of light shielding plates to the total area of the front face of the light shielding plates is an arithmetic progression. The ultraviolet light shading structure can be used for a composite film semi-curing process through a series of replaceable shading plates, so that a flexible ultraviolet light weakening effect is achieved, different shading plates can be replaced according to different proces
