Solution Overview
Problem
Conventional dedusting methods struggle to effectively remove metal dust from the surface of material belts, especially when the dust is embedded in a coating layer, leading to quality issues in the final product.
Innovation Solution
A dedusting apparatus with a magnetic mechanism generating an alternating magnetic field and a dust suction mechanism arranged opposite to each other, causing metal dust to be repelled from the material belt and easily collected by the suction mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dedusting methods (blower, negative pressure, adhesion) are used, then the structure is simple, but metal dust cannot be effectively removed from the material belt surface
Solution Approach 1:
The patent replaces conventional mechanical dedusting methods (blowers, negative pressure systems) with a magnetic field-based system. A magnetic roller generates a magnetic field that interacts with metal dust particles, causing them to be repelled from the material belt surface through electromagnetic induction, thereby achieving effective metal dust removal without complex mechanical components
Solution Approach 2:
The patent changes the physical state or properties of the dedusting mechanism by introducing a magnetic field. The magnetic roller generates a time-varying magnetic field that induces eddy currents in metal dust particles, changing their magnetic properties and causing repulsion. This parameter change enables effective removal of metal dust that conventional methods cannot handle
2Manufacturing precision
If a magnetic roller is added to generate alternating magnetic field, then metal dust removal effectiveness is improved, but the device structure becomes more complex
Solution Approach 1:
The patent replaces complex mechanical dedusting mechanisms with a magnetic field-based system. The magnetic roller, driven by a simple motor, generates a magnetic field that automatically interacts with metal dust particles, eliminating the need for complex mechanical structures while achieving superior metal dust removal effectiveness
Solution Approach 2:
The magnetic roller serves multiple functions: it generates the alternating magnetic field needed for dust removal, acts as a driving element through its rotation, and can be integrated with the existing material belt conveying system. This multi-functionality reduces overall device complexity while maintaining high dedusting effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively reduces metal dust residue and improves the dedusting effect by using an alternating magnetic field to induce a repulsive force, ensuring the material belt is clean and enhancing the quality of battery manufacturing processes.
Implementation Method 1
the magnetic mechanism is used for generating an alternating magnetic field... metal dust passing through the gap with the material belt is affected by the alternating magnetic field and induced to form an eddy current

AI summary
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.
