Multi-layer hot pressing mechanism of battery

The multi-layer hot-pressing mechanism comprises an electric cylinder, a top plate, guide stand columns and a hot-pressing module, the tops of the guide stand columns are fixedly installed at the four corners below the top plate through locking nuts respectively, the electric cylinder is fixedly arranged on the top plate, and the output end of the electric cylinder penetrates through the top plate to be connected with a hot-pressing push plate. The hot-pressing push plate is connected with a hot-pressing top plate through four guide rods, the tops of the guide rods penetrate through the top of the top plate, multiple hot-pressing mounting plates are arranged at the bottom of the hot-pressing top plate, and hot-pressing modules are fixedly mounted on the opposite hot-pressing faces of the hot-pressing top plate and the multiple hot-pressing mounting plates. Hot-pressing air cylinders are arranged on the two sides of the hot-pressing module between the hot-pressing top-layer plate and the opposite hot-pressing
