Center-Driven Cutter Assembly for Guide Rod Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cutting mechanisms in battery manufacturing suffer from poor cutting efficiency due to uneven stress distribution on guide rods, leading to wear and inclining guide rods, which result in gaps between the moving and stationary cutters, causing burrs and poor cutting performance.
Innovation Solution
A cutting mechanism with a driving assembly connected to the centerline of the mounting piece, ensuring equal stress distribution on both sides, and a feeding device with a clamping mechanism to improve cutting accuracy and efficiency by synchronously sliding with the cutting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the driving assembly is connected to one end of the guide rod frame, then the structure is simple, but the stress is concentrated causing severe wear and inclining guide rod
Solution Approach 1:
The patent divides the force application into multiple points by connecting the driving assembly to both ends of the guide rod frame rather than one end. This segmentation of the force application distributes the stress along the guide rod, preventing concentrated wear at a single location and maintaining guide rod reliability.
2Device complexity
If the guide rod is subjected to concentrated stress, then the driving assembly can be simply connected, but the guide rod becomes inclined causing gap between cutters
Solution Approach 1:
The force application is segmented into two connection points at both ends of the guide rod frame. This distributes the driving force and prevents the guide rod from becoming inclined due to concentrated stress, thereby maintaining the parallelism between moving and stationary cutters and ensuring cutting precision.
3Device complexity
If the guide rod frame has force application point at one end, then the driving assembly connection is simple, but wear is uneven causing inclining guide
Solution Approach 1:
The connection structure is modified to segment the force application into two points at both ends of the guide rod frame. This creates uniform stress distribution along the guide rod, preventing uneven wear and maintaining the stability of the guide rod's parallel composition throughout its length.

AI summary
The application relates to a cutting mechanism and a feeding device. The cutting mechanism comprises a cutter holder; a stationary cutter fixedly arranged on the cutter holder; a moving cutter assembly comprising a mounting piece and a moving cutter, the mounting piece being slidably arranged on the cutter holder in a first direction, the moving cutter being mounted on the mounting piece, and the mounting piece having a centerline parallel to the first direction; and a driving assembly comprising a first end and a second end, the first end being matched with a guide mechanism, and the second end being connected with a part of the mounting piece corresponding to the centerline; when the cutter holder drives parts located thereon to move in a second direction, the guide mechanism can drive the driving assembly to apply a driving force to the mounting piece in the first direction.
