Coating jig and coating device

The invention relates to a coating jig and a coating device. The coating jig comprises a frame body, the frame body is provided with four side edges, each side edge comprises a side edge body and a bulge extending from the side edge body into the frame body, each side edge body forms a membrane space at one side of the bulge in a surrounding manner, and each bulge is used for bearing a membrane inthe membrane space; and a first inclined surface is formed on the side, facing the membrane space, of each side edge body, and when the membrane is erected on the bulges, a gap is formed between theedge of the membrane and the first inclined surface of each side edge body. When the membrane is erected on the four bulges, the gaps are formed between the edge of the membrane and the first inclinedsurfaces, so that vacuum coating is convenient through the gaps between the edge of the membrane and the first inclined surfaces during coating, the coating rate of the edge of the membrane is increased, and the overall coatin
