Electrode Lead Alignment with Backward-Moving Guide Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode lead alignment apparatuses fail to effectively handle product tolerances during the alignment of electrode leads, leading to potential damage such as scratching or crumpling due to inadequate support and pressure distribution.
Innovation Solution
The proposed electrode lead alignment apparatus incorporates a backward movement device and guide rollers to manage product tolerances. The backward movement device allows for backward movement of the movement guide when it encounters an electrode lead with a tolerance, preventing damage. Guide rollers disperse surface pressure applied to the electrode lead during alignment, further preventing damage.

Engineering Contradiction Analysis
1Manufacturing precision
If a fixed movement guide is used to align electrode leads, then alignment precision is improved, but electrode leads with tolerance may be damaged due to excessive pressure
Solution Approach 1:
The movement guide is designed with backward movement capability, transforming from a fixed rigid structure to a dynamic adaptive structure. When an electrode lead with larger tolerance encounters the movement guide, the guide can move backward by a predetermined distance to accommodate the tolerance, preventing excessive pressure and damage while maintaining alignment precision for standard-sized leads.
Solution Approach 2:
The system changes the positional parameter of the movement guide dynamically. By allowing the movement guide to move backward, the contact position and pressure distribution are adjusted according to the actual size of the electrode lead, resolving the conflict between alignment precision and damage prevention.
2Productivity
If a movement guide moves by a fixed stroke to align electrode leads, then alignment efficiency is improved, but electrode leads with tolerance greater than expected may be crumpled or scratched
Solution Approach 1:
The movement guide incorporates backward movement functionality that activates when electrode leads with larger tolerances are encountered. This dynamic adjustment prevents the fixed stroke from causing crumpling or scratching, while maintaining efficient alignment for standard leads through the normal forward movement stroke.
Solution Approach 2:
The system prepares for potential tolerance variations by designing the movement guide with backward movement capability in advance. This preemptive design ensures that when electrode leads with unexpected tolerances are encountered, the guide can retreat to prevent damage, cushioning against the harmful effects before they occur.

AI summary
An electrode lead alignment apparatus for manufacturing a battery includes: an alignment support configured to place an electrode lead thereon; a first-direction movement guide configured to push the electrode lead on the alignment support in a first direction to align the electrode lead; a first-direction movement member configured to be moved by a set first-direction movement stroke in the first direction, and connected to the first-direction movement guide to move the first-direction movement guide in the first direction; and a first-direction movement guide backward movement device configured to move the first-direction movement guide backward in a direction opposite in a direction in which the first-direction movement member is moved forward, when the electrode lead is stopped due to completion of alignment of the electrode lead by the first-direction movement guide during forward movement of the first-direction movement member in the first direction.
