Abstract: In a material verification method, information of newly loaded materials in a production line is obtained. It is determined whether the information has been verified. If the information has not been verified, it is determined whether a tray supporting the newly loaded materials has been switched from use in producing a first product to use in producing a second product. If the tray supporting the newly loaded materials is not switched to use in producing the second product, the information of the newly loaded materials is presented to a user for material verification. A system for administering such method and a device applying the method are also disclosed.

Abstract: An electric vehicle automatic charging system includes an electric vehicle including a receiving cavity with an opening and a shutter for closing the opening, a battery assembly receiving in the receiving cavity and a charging device. The battery assembly includes a battery pack including an electrode connecting member and a movable bracket including a magnetic member. The charging device includes a support table, a support plate, an electromagnetic fitting member being capable of generating a magnetic force for attracting the magnetic member, and a charger. When the shutter comes into contact with the support plate, the shutter changes from a closed state to an open state, the movable bracket drives the battery pack to move away from the receiving cavity along the support plate by the magnetic force until the electrode connecting member is electrically connected to the charger. An electric vehicle automatic charging method is also provided.

Abstract: A flatness sensing device includes a pressure sensing unit and a controller. The pressure sensing unit includes a plate portion, and a pressure sensor fixed and exposed at an edge of the plate portion. A sensing surface of the pressure sensor is flush with the bottom surface of the plate portion. The pressure sensor senses a pressure or lack of pressure of an object to be tested when it touches the object to be tested. The controller receives the pressure value output from the pressure sensor and determines a flatness of the object to be tested, the controller can issue an alarm on finding non-flatness and cause the degree of flatness to be displayed to a user.
