This application discloses a power battery top cover loading mechanism, belonging to the technical field of battery top cover loading equipment. It mainly includes: a belt conveyor and a lifting assembly installed at one end of the belt conveyor. The lifting assembly includes frames installed on both sides of the belt conveyor, each frame having a fixed plate, and each fixed plate having a support plate. This power battery top cover loading mechanism, through the arrangement of a positioning plate and a drag plate, ensures that when the drag plate drives the pallet downwards, the positioning plate remains in contact with the side of the pallet, providing stable lateral limiting through surface contact and ensuring the pallet's horizontal positional accuracy. When the pallet is conveyed to the belt conveyor, the extended portion of the positioning plate remains in contact with the side of the pallet until the pallet fully enters the conveyor belt's transmission channel, thereby effectively reducing displacement deviations caused by inertia or vibration during pallet transfer.
