Solution Overview
Problem
Existing technologies face challenges in efficiently sorting and identifying abnormally sized battery cells, which can lead to manufacturing defects and potential safety issues.
Innovation Solution
An apparatus with a transfer device, sorting jig, guide protrusions, detection sensor, alarm, and remover is used to sort abnormal battery cells by guiding normal-sized cells into an insertion portion and alerting operators, while automatically removing abnormal cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sorting method is implemented to separate abnormal battery cells, then manufacturing precision and safety are improved, but device complexity increases
Solution Approach 1:
The battery cell itself serves as the sorting criterion through its physical size. Normal-sized cells automatically pass through the insertion portion while abnormal cells are blocked, eliminating the need for complex external measurement and control systems. The sorting action is performed passively by the cells' own dimensions interacting with the fixed insertion portion geometry.
Solution Approach 2:
The abnormal battery cells are extracted from the production line through the sorting jig and removed separately. The insertion portion acts as a selective barrier that allows normal cells to pass while extracting abnormal cells for separate handling, achieving separation without requiring complex sorting mechanisms for each individual cell.
2Productivity
If real-time detection of abnormal battery cells is implemented, then productivity and quality control are improved, but device complexity and cost increase
Solution Approach 1:
The abnormal battery cells automatically trigger the detection and alarm system through their own physical presence blocking the insertion portion. The cells themselves provide the signal for detection without requiring external active sensing mechanisms, enabling real-time identification through passive physical interaction.
Solution Approach 2:
The detection sensor provides immediate feedback when an abnormal cell blocks the insertion portion, triggering the alarm system to notify operators. This closed-loop feedback mechanism enables real-time detection and response to abnormal cells, ensuring immediate quality control intervention without complex continuous monitoring systems.
3Productivity
If automatic removal of abnormal battery cells is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The abnormal battery cells are automatically removed from the production line through the remover mechanism triggered by their own presence blocking the insertion portion. The cells themselves initiate the removal process without requiring complex active grasping or manipulation systems, achieving automated separation through passive triggering of the removal mechanism.

AI summary
An apparatus for sorting an abnormal battery cell includes a transfer device including a moveable transfer path, battery cells being transferred along the moveable transfer path, a sorting jig on the transfer device, the sorting jig including an insertion portion facing the moveable transfer path of the transfer device, and the insertion portion having a shape and a size equal to an outer shape and a size of a predetermined battery cell, and an alarm on the transfer device, the alarm being configured to notify if the abnormal battery cell among the battery cells has a shape or a size larger than the outer shape and the size of the predetermined battery cell.
