摘要： A dust removal apparatus (300), a battery manufacturing device (100) and a dust removal method. The dust removal apparatus (300) is used for removing dust from a surface of a material belt (3), and comprises a dust suction mechanism (1) and a magnetic mechanism (2), wherein the magnetic mechanism (2) and the dust suction mechanism (1) are arranged opposite and spaced apart from each other, so as to form a gap for the material belt (3) to pass through, and the magnetic mechanism (2) is used for generating an alternating magnetic field. A magnetic mechanism (2) and a dust suction mechanism (1), which are opposite each other, are provided on two sides of the thickness direction of a material belt (3), and when the material belt (3) passes through a gap between the magnetic mechanism (2) and the dust suction mechanism (1), metal dust passing through the gap along with the material belt (3) is subjected to the action of an alternating magnetic field and is induced to form an eddy current, such that the metal dust generates an inducted magnetic field having a direction opposite to the direction of the original alternating magnetic field, and the metal dust is subjected to a repulsive force and is bounced off the material belt (3); the dust suction mechanism (1) sucks away the bounced-off metal dust, thereby effectively reducing metal dust residues; and moreover, the dust collection mechanism (1) can also suck away other dust having a small dead weight, thereby effectively improving a dust removal effect.

摘要： An automatic case separating apparatus (100) and method and a case separation system are provided. In a separation process, unpacked cases (600) are placed upside down on a feeding mechanism (110), the feeding mechanism is used to deliver a whole box of cases to a delivery mechanism (120), and it is ensured that the cases are delivered in a tipped posture on the delivery mechanism. Then, a combing mechanism (130) is used to separate at least two overlapping cases. After the cases are separated from each other, a spacer (620) is exposed on the delivery mechanism, and at this time, the spacer is removed from the delivery mechanism by using a removing mechanism (140). After paper removal, the separated cases are delivered to a loading process under the action of the delivery mechanism. When the cases are delivered to a discharging mechanism (200), the cases on the discharging mechanism are transferred to an empty tray (500) in a tray supplying apparatus (400) through a material picking apparatus(300). In this way, the automatic case separating apparatus can replace manual work, so that the packaged cases are automatically and orderly separated, and automatic and effective paper removal operations are performed, thereby speeding up the operation pace, and improving the separation efficiency and separation quality.
