Electrode Plate Tab Cutting Waste Adsorption Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During electrode plate processing, the incomplete cutting of tabs leads to unstable cutting mechanisms due to shaking waste edges, which can cause laser defocusing and result in material waste and increased costs, as a roller cutting method is required to minimize shaking, necessitating a 5-8 mm offcut.
Innovation Solution
An electrode plate processing device with a waste adsorption mechanism comprising an active driving roller, driven support roller, and conveyer belt, equipped with negative pressure holes and vacuum rollers, to stabilize and adsorb the waste edge, ensuring continuous cutting stability without material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser cutting mechanism is used to cut electrode plate to form tab, then cutting speed and efficiency are improved, but waste edge shakes during conveying causing laser defocus and degraded cutting stability
Solution Approach 1:
The patent applies preliminary anti-action by introducing a waste edge adsorption mechanism that actively counteracts the shaking of waste edge before it can cause laser defocus. The adsorption mechanism includes a adsorption roller with adsorption holes that generate negative pressure to firmly hold the waste edge during conveying, preventing the harmful shaking motion from occurring in the first place. This resolves the contradiction by maintaining cutting stability while preserving the high efficiency of laser cutting.
2Reliability
If roller cutting method is incorporated to minimize waste edge shaking, then cutting stability is improved, but 5-8 mm offcut must be reserved leading to material waste and increased cost
Solution Approach 1:
The patent applies the taking out principle by extracting and separately handling the waste edge through the adsorption mechanism. Instead of requiring a large offcut margin to prevent shaking, the system extracts the waste edge immediately after cutting and holds it firmly during conveying. This allows the cutting process to achieve stability with minimal or no reserved offcut, thereby reducing electrode plate material waste while maintaining cutting reliability.
3Productivity
If waste edge is not completely cut off, then continuous cutting process is maintained, but waste edge shakes causing laser defocus and degraded tab quality
Solution Approach 1:
The patent applies the intermediary principle by introducing the waste edge adsorption mechanism as a mediator between the cutting process and the conveying system. The adsorption roller with negative pressure generation acts as an intermediary that firmly holds the partially connected waste edge during conveying, preventing it from shaking and causing laser defocus. This allows the continuous cutting process to proceed while maintaining tab quality by eliminating the harmful shaking effect.

AI summary
An electrode plate processing device is provided. The electrode plate processing device includes: an electrode plate conveying mechanism configured to convey an electrode plate; a cutting mechanism disposed opposite to the electrode plate and configured to cut the electrode plate to form a tab; and a waste adsorption mechanism disposed downstream of the cutting mechanism along a conveying direction of the electrode plate. The waste adsorption mechanism includes an active driving roller, a driven support roller, and a conveyer belt that is coupled to the active driving roller and the driven support roller in a transmission way. The conveyer belt is driven by the active driving roller to rotate and configured to provide an adsorption force to a waste edge produced during the cutting of the electrode plate so as to adsorb the waste edge.
