Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dust removal brush is used to clean weld slag, then cleaning effect is improved, but weld slag may scatter to other parts or environment
Solution Approach 1:
The patent employs a dust removal cover that acts as a flexible shell to enclose the dust removal brush and contain weld slag within a defined space. The cover prevents weld slag from scattering to surrounding areas while allowing the brush to effectively clean the electrode post surface.
2Productivity
If the dust removal brush moves along a direction to clean larger area, then productivity is improved, but control precision may be reduced
Solution Approach 1:
The patent implements a movable dust removal brush that can travel along the electrode post in a first direction to cover larger cleaning areas. The brush is driven by a drive assembly that enables controlled movement, maintaining cleaning precision while expanding the effective cleaning coverage.
3Reliability
If the dust removal cover is designed to exactly match the electrode post shape, then reliability is improved, but device complexity increases
Solution Approach 1:
The dust removal cover is designed as a flexible shell structure that can adapt to the electrode post geometry. The cover includes a port with specific dimensional relationships (length L1 greater than width L2) that allows it to conform to the electrode post while maintaining structural simplicity and reliable coverage.
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 efficiently cleans weld slag, reducing contamination risks by isolating the electrode post from the environment and minimizing scattering, while enhancing cleaning efficiency through vibration and airflow.
Implementation Method 1
the dust removal brush is configured to be able to move back and forth along the first direction within the dust removal cover
Implementation Method 2
the plug can be pressed onto the interior of the hollow electrode post of the battery cell preform, sealing a gap at a bottom opening of the hollow electrode post
Implementation Method 3
an air inlet is disposed on the sidewall of the dust removal cover, so that external air can enter the dust removal cover, allowing weld slag dislodged by the dust removal brush to be carried away by the airflow

AI summary
The present application provides a dust removal device and a battery production system. The dust removal device comprises dust removal assemblies and a first driving assembly. Each dust removal assembly comprises a dust removal brush, and the first driving assembly is connected to the dust removal brush and is configured to be capable of driving the dust removal brush to move in a first direction. In this way, the dust removal brush can clean weld spatters while moving, allowing for a large area of removal of weld spatters on hollow poles of battery cell preforms; and furthermore, the dust removal brush can achieve cleaning of strip-shaped weld marks, improving the cleaning effect of the dust removal device.
