Dedusting apparatus, battery manufacturing device, and dedusting method

A battery manufacturing device, comprising:

• a conveying apparatus used for conveying an electrode plate material belt for a lithium-ion battery;
• a cutting apparatus used for cutting the electrode plate material belt;
• and
• a dedusting apparatus arranged downstream of the cutting apparatus and used for removing dust on a surface of the electrode plate material belt, wherein the dedusting apparatus comprises:
• a dust suction mechanism;
• and
• a magnetic mechanism, arranged opposite to the dust suction mechanism at an interval to form a gap for the material belt to pass through,
• wherein the magnetic mechanism comprises:
• a magnetic roller configured to generate an alternating magnetic field when rotating and cause a metal dust on a surface of the material belt to generate an induced magnetic field opposite to the alternating magnetic field, so that the metal dust is subjected to a repulsive force and bounces off from the material belt for the dust suction mechanism to suck away;
• a driving assembly comprising a motor configured to drive the magnetic roller to rotate, wherein the motor comprises an output shaft connected to one end of the magnetic roller;
• and
• a mounting seat, wherein both of two ends of the magnetic roller are rotatably connected to the mounting seat, and the driving assembly is fixedly connected to the mounting seat, wherein the mounting seat comprises a first end wall, a second end wall, and a bottom wall, wherein the first end wall and the second end wall are relatively arranged on both sides of the material belt along a width direction of the material belt, the bottom wall is connected to one end of the first end wall and one end of the second end wall, both of the two ends of the magnetic roller are rotatably connected to the first end wall and the second end wall respectively, the driving assembly is mounted on the first end wall, and one of the two ends of the magnetic roller connected to the first end wall passes through the first end wall to connect to the output shaft of the motor.
