Electrode Cutting Cartridge for Knife Clearance and Squareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrode cutting apparatuses require complex assembly processes and struggle to maintain the clearance and squareness between upper and lower knives, leading to difficulties in adjusting the blades' alignment and potential bending, which affects cutting quality and productivity.
Innovation Solution
An all-in-one cutting cartridge module integrating an upper knife and a lower knife, mounted on a unified module frame, allows for simple assembly and precise adjustment of clearance and squareness, using a cradle and driving unit for vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the upper knife and lower knife are independently assembled in separate frames, then the assembly structure is flexible, but the clearance and squareness between knives cannot be maintained within tolerance range
Solution Approach 1:
The patent combines the upper knife and lower knife into a single integrated cartridge assembly where both knives are mounted on the same frame structure. This merging allows the knives to be pre-aligned and secured together, ensuring that clearance and squareness are maintained within tolerance ranges during operation, while still allowing the entire cartridge to be replaced as a single unit for maintenance.
2Manufacturing precision
If the slope of the upper knife is adjusted using a non-head bolt, then the squareness between knives can be corrected, but the upper knife may bend due to cantilever type moment
Solution Approach 1:
The patent extracts the adjustment function from the knife blade itself and relocates it to the cartridge assembly structure. By providing adjustment mechanisms at the cartridge level rather than directly on the knife, the design eliminates the cantilever moment that would bend the knife blade, while still enabling precise control of knife alignment and squareness.
3Ease of manufacture
If multiple assembly steps are required for the cutting apparatus, then each component can be optimized independently, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent segments the cutting apparatus into modular components, with the upper knife, lower knife, and their supporting structures organized into a standardized cartridge assembly. This segmentation allows each component to be optimized independently during manufacturing, while the modular cartridge design enables rapid assembly and replacement, significantly improving productivity by reducing the number of assembly steps required.

AI summary
An apparatus for cutting an electrode of a battery includes: an all-in-one cutting cartridge module including an upper knife and a lower knife; and a cradle where the all-in-one cutting cartridge module is mounted. The all-in-one cutting cartridge module includes a module frame and an upper knife holding unit which fixes and supports the upper knife and is supported in a manner that is vertically slidable on the module frame, and the lower knife is coupled to a lower portion of the module frame to face the upper knife. The upper knife and the lower knife are installed at the module cartridge, it is possible to quantitatively adjust the clearance and straightness of the upper knife and the lower knife in advance.
