A material feeding region and a material discharging region are formed on the arc-shaped guide surface, which is further provided with first suction holes. Second suction holes run through the conveyor belt. The conveyor belt is wound on the arc-shaped guide surface, and seals the first suction holes. The driver is for driving the conveyor belt to move. The stripper is for extending to the position between the conveyor belt and the electrode sheet. In the present utility model, the electrode sheet can be automatically turned.

Abstract: A method for determining a physical state of a movable object includes determining an estimated physical state based on first sensing data obtained by a first sensing system of the movable object, during a time duration in which second sensing data from a second sensing system is unavailable or is not updated; in response to determining that the second sensing data from the second sensing system becomes available or is updated, determining an observed physical state of the movable object based on the second sensing data; and based on a deviation between the observed physical state and the estimated physical state of the movable object, determining whether to update the physical state of the movable object based on the observed physical state. The first and second sensing systems have different sampling frequencies. The deviation is indicative of a validity of the sensing data of the second sensing system.
