Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During battery production, smoke and welding slag generated during welding operations can accumulate and negatively impact the welding process, leading to poor welding quality and potential seam collapse if not promptly removed.
Innovation Solution
A dust extraction apparatus comprising a copper nozzle with a penetrating channel, a cover plate with a through hole, and a dust extraction assembly with a suction apparatus, which creates negative pressure to extract impurities like smoke and welding slag from the welding region, reducing their impact on the welding operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If welding operations are performed during battery production, then battery components can be joined, but smoke and welding slag are generated and accumulate, negatively impacting welding quality
Solution Approach 1:
The patent extracts harmful impurities (smoke and welding slag) from the welding region using a dust extraction assembly with suction channels. The extraction assembly is positioned adjacent to the welding region and uses negative pressure generated by a suction device to draw out smoke and welding slag through channels, preventing their accumulation and maintaining welding quality.
Solution Approach 2:
The patent introduces a dust extraction assembly as an intermediary system between the welding source and the welding region. This assembly includes extraction channels and a suction device that mediates the removal of harmful factors, allowing welding to proceed without the negative effects of smoke and slag accumulation.
2Manufacturing precision
If a dust extraction assembly is added to remove smoke and welding slag, then welding quality improves, but device complexity increases
Solution Approach 1:
The patent merges the dust extraction assembly with the existing welding device structure. The extraction assembly is integrated into or positioned adjacent to the welding apparatus, sharing space and structural elements where possible. This combination reduces the need for completely separate systems and minimizes overall device complexity while maintaining effective dust extraction.

AI summary
This application provides a dust extraction apparatus and a battery production line. A copper nozzle is disposed on a first end face of a cover plate, and a channel of the copper nozzle communicates with a through hole of the cover plate. A dust extraction assembly is disposed on a second end face, and a cavity having a first port and a second port is formed in the interior of the dust extraction assembly. The first port faces the through hole, and a suction apparatus is connected to the second port. The dust extraction apparatus in embodiments of this application can extract dust via the first port of the dust extraction assembly facing the through hole, thus promptly exhausting impurities such as smoke and welding slag generated during welding.
