The utility model relates to a lifting feeding device. The lifting mechanism is used for bearing a workpiece and comprises a lifting platform. Bearing mechanism, the device comprises a bearing plate,supporting columns and ball assemblies. The bearing plate is installed on the lifting platform, the multiple supporting columns are arranged in parallel, one ends of the multiple supporting columns are connected with the bearing plate, the ball assemblies are arranged at the other ends of the supporting columns, and the ends of the ball assemblies can roll and make contact with the workpiece. Andthe bearing plate can do reciprocating motion in the gravity direction of the workpiece along with the lifting platform. Due to the fact that the ends of the ball assemblies can roll, when a workpieceis placed on the ball assemblies, the placing direction of the workpiece can be automatically adjusted through the synergistic effect of the multiple ball assemblies, the workpiece cannot incline relative to the reference horizontal plane, and the parallelism of the workpiece relative to the reference horizontal plane is guaranteed.
