Substrate loading jig

The utility model relates to the technical field of packaging carrier plates, in particular to a substrate loading jig. The device comprises a fixing frame, the fixing frame comprises four stand columns, every two of the four stand columns are connected through cross beams, clamp fixing frames are symmetrically installed on the two sides of the fixing frame, a plurality of clamps are installed on the clamp fixing frames, and a supporting frame is further arranged between the cross beams at the bottom end. The upper clamp fixing frame and the lower clamp fixing frame are arranged, sliding rails are arranged on the clamp fixing frames, and the clamps are arranged in the sliding rails in a sliding mode; the number of the supporting frames is two, and a plurality of V-shaped grooves are formed in the upper ends of the supporting frames. The substrate can be fixed through the clamp, the risk that the substrate is scratched due to collision and friction is reduced, and the yield is improved. 本实用新型涉及封装载板技术领域，具体涉及一种基
