Workpiece lifting mechanism and assembling device

The utility model provides a workpiece lifting mechanism and an assembling device. The workpiece lifting mechanism is used for enabling a first matching face of a workpiece to be matched with a second matching face of equipment, the workpiece lifting mechanism comprises a base and a plurality of lifting units, each lifting unit comprises a lifting piece and a connecting piece, and the lifting pieces are rotationally connected with the base. One end of the connecting piece is rotationally connected with the lifting piece, and the other end is rotationally connected with a workpiece. The lifting piece can lift the workpiece, so that the workpiece is rotated and adjusted while being lifted, and then the first matching surface of the workpiece is matched with the second matching surface of the equipment. According to the workpiece lifting mechanism, the base, the lifting piece, the connecting piece and the workpiece are rotationally connected in sequence, so that the connected parts can rotate relative to each ot
