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.

Abstract: Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.
