  • Publication number: 20250091142
    Abstract: An electrode plate molding device is disclosed, including a conveying mechanism, a cutting mechanism, a first detection mechanism, and a deviation rectification mechanism. The conveying mechanism is configured to convey an electrode plate strip. The cutting mechanism is arranged downstream of the conveying mechanism along a conveying direction of the electrode plate strip. The cutting mechanism is configured to cut the electrode plate strip to form an electrode plate. The first detection mechanism is located upstream of the cutting mechanism along the conveying direction. The first detection mechanism is configured to detect a location of the electrode plate strip along a width direction of the electrode plate strip. The deviation rectification mechanism adjusts relative locations of the electrode plate strip and the cutting mechanism along the width direction in response to a detection result of the first detection mechanism.

  • Publication number: 20240293854
    Abstract: Disclosed are a dedusting apparatus, a battery manufacturing device, and a dedusting method. The dedusting apparatus is used for removing dust on the surface of a material belt, and includes a dust suction mechanism and a magnetic mechanism, wherein the magnetic mechanism is arranged opposite to the dust suction mechanism at an interval to form a gap for the material belt to pass through, and the magnetic mechanism is used for generating an alternating magnetic field. By arranging the magnetic mechanism and the dust suction mechanism opposite to each other on both sides of the material belt in the thickness direction, when the material belt passes through the gap between the magnetic mechanism and the dust suction mechanism, metal dust passing through the gap along with the material belt is affected by the alternating magnetic field and induced to form an eddy current.
