Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling is used for faulty battery cells, then flexibility in handling defects is maintained, but processing time increases and production capacity decreases
Solution Approach 1:
The system enables automatic self-inspection and self-replacement of faulty battery cells. The inspection apparatus automatically detects gluing position defects, and the pick-and-place apparatus automatically replaces defective cells without manual intervention, thus maintaining operational flexibility while significantly improving production capacity.
Solution Approach 2:
The patent replaces manual mechanical handling with automated inspection and replacement systems. The inspection apparatus uses image processing to detect defects, and the pick-and-place apparatus uses automated mechanical systems to replace faulty cells, eliminating the need for manual labor while maintaining adaptability to various defect types.
2Measurement precision
If manual gluing inspection is performed, then detection accuracy can be adjusted flexibly, but inspection time increases and affects production efficiency
Solution Approach 1:
The patent replaces manual visual inspection with an automated inspection apparatus that captures images of battery cell gluing positions and uses image processing algorithms to automatically detect defects. This substitution maintains high detection accuracy while dramatically reducing inspection time, as the automated system can process multiple cells rapidly without fatigue or distraction.
Solution Approach 2:
The inspection apparatus operates continuously alongside the production line, performing inspections on each battery cell as it passes through without interrupting the manufacturing flow. This continuous operation eliminates the time loss associated with batch manual inspection while maintaining consistent detection accuracy across all cells.
3Productivity
If faulty battery cells are grouped and processed normally, then production flow is maintained, but heat dissipation and service life are affected
Solution Approach 1:
The inspection apparatus performs preliminary detection of gluing position defects before the battery cells are grouped and assembled into final products. By identifying and flagging faulty cells in advance, the system prevents defective cells from being incorporated into battery packs, thereby maintaining production flow while ensuring the reliability and service life of the final products.
Solution Approach 2:
The system implements a feedback mechanism where inspection results are immediately communicated to the pick-and-place apparatus, which then selectively replaces faulty cells before grouping. This closed-loop feedback ensures that only quality-assured cells proceed to assembly, maintaining both production efficiency and product reliability by preventing defective cells from affecting overall battery pack performance.

AI summary
A gluing position inspection method, device, and system resolve at least problemst such as long treatment time, high costs, a low production capacity, and the influence of omission of regluing on heat dissipation and performance of a battery pack caused due to online manual regluing. The inspection method is applied to an inspection device. The inspection method includes: determining an inspection result of a current battery cell based on an image of a surface of the current battery cell, where the image of the surface of the current battery cell is captured by the inspection apparatus at an inspection position, and the image of the surface of the current battery cell includes a gluing position; and controlling a picking portion of the pick-and-place apparatus to move the current battery cell to the cache apparatus and move a spare battery cell in the storage apparatus to the inspection position.
