Label Attaching Device for Defective Battery Electrodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of secondary batteries often results in defective electrodes due to contamination or pinhole defects, leading to reduced performance and the need for electrode discarding, which is inefficient and costly.
Innovation Solution
A label attaching device is developed, comprising a substrate moving unit, a labeler, and moving units that allow for the automatic and precise attachment of labels to defective electrode portions, enabling efficient identification and disposal of defective electrodes, with the labeler including an unwinder, extruder, presser, and ejector for label application, and moving units for parallel and perpendicular movement to accommodate both mobile and stationary substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a label attaching device is designed to handle both mobile and stationary substrates, then the device's versatility is improved, but the device complexity increases due to multiple moving units
Solution Approach 1:
The label attaching device is designed with a dual moving unit system: a first labeler moving unit that moves the labeler in the first direction (parallel to substrate movement) and a second labeler moving unit that moves the labeler in the second direction (perpendicular to substrate movement). This multi-functional design enables the single labeler to handle both mobile substrates (using first direction movement) and stationary substrates (using second direction movement), thereby achieving versatility without requiring separate devices for each application scenario.
2Productivity
If the labeler can move in parallel direction to substrate movement, then the productivity is improved by labeling multiple substrates, but the device complexity increases
Solution Approach 1:
The first labeler moving unit enables the labeler to move continuously in the first direction (parallel to substrate movement) along the substrate conveying path. This continuous movement capability allows the labeler to sequentially label multiple substrates as they pass through, maintaining continuous productive action without requiring stopping or repositioning between substrates, thereby significantly improving productivity.
Solution Approach 2:
The first labeler moving unit employs a gear mechanism with first teeth and second teeth that engage with each other to transmit motion. This intermediary mechanical linkage converts rotational motion from the first drive unit into linear motion of the labeler along the first direction, enabling precise and controlled movement of the labeler parallel to substrate movement for efficient multi-substrate labeling.
3Productivity
If the substrate is moved before or after being slit, then the manufacturing efficiency is improved, but the manufacturing precision may be affected
Solution Approach 1:
The label attaching device is designed to operate dynamically during substrate movement. The labeler can be positioned and activated at specific moments while the substrate is being conveyed in the first direction, allowing labeling to occur either before or after slitting without requiring the substrate to be completely stationary. This dynamic operation maintains manufacturing efficiency while achieving acceptable labeling precision through controlled positioning during motion.
