Press fitting device for assembling semiconductor element

The invention discloses a press fitting device for assembling a semiconductor element. The press fitting device comprises a carrying table, a press fitting box is arranged at the top of the carrying table; a press fitting plate for storing the semiconductor element is arranged in the press fitting box; a plurality of accommodating grooves are formed in the press fitting plate; an overturning assembly for driving the press fitting plate to overturn is arranged in the press fitting box; and buffering assemblies used for buffering the press fitting plate are symmetrically arranged on the two sides of the bottom of the overturning assembly. According to the press fitting device, the press fitting box and a press fitting assembly are arranged, a press fitting roller on the press fitting assembly is matched with the press fitting plate on the press fitting box, and then a cooling fin is effectively pressed to the semiconductor element; and the buffering assemblies are arranged at the bottom of the press fitting pla
