A driving seat is installed on the movable guide rail, and a detection mechanism is installed on the driving seat. Two movable guide rails are installed on both sides of the electric vehicle frame, and two driving seats are installed on the movable guide rails. When the technical solution is in use, it conveys the electric vehicle battery to the side of the detection mechanism and below the maintenance mechanism for detection and welding maintenance through a conveyor belt. However, when the structure is in use, the conveyor belt is used to move the electric vehicle battery.
