Battery Module Part Verification for Supply Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module manufacturing processes face challenges in preventing parts supply errors, leading to incorrect assembly due to mismatched or improperly oriented parts, which can disrupt the production line and affect the quality of battery modules.
Innovation Solution
An apparatus and method that utilizes code readers and check sensors in assembly equipment to verify part identification, orientation, and recipe matching through a dual determination process involving both assembly equipment and an equipment management system, ensuring parts are correctly identified and oriented before assembly, and stopping operations if errors are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single determination step is used to verify part-recipe matching, then the verification process is simple and fast, but the reliability of error prevention is insufficient
Solution Approach 1:
The verification process is divided into two independent determination steps: first determination by assembly equipment and second determination by equipment management system. Each step independently verifies part-recipe matching, providing redundant verification to enhance reliability while distributing system complexity across multiple components rather than concentrating it in a single verification mechanism.
Solution Approach 2:
The system implements feedback loops where the results of both determination steps are evaluated together. If either determination finds a mismatch, the system stops operation and outputs an alarm. This feedback mechanism ensures that errors are caught at multiple stages, significantly improving parts supply error prevention reliability.
2Reliability
If multiple determination steps are implemented to verify part-recipe matching, then the reliability of error prevention improves, but the operation time increases
Solution Approach 1:
The first determination step is performed by the assembly equipment before the second determination step by the equipment management system. This preliminary verification catches obvious mismatches early in the process, allowing the second determination to focus on deeper verification. The sequential arrangement optimizes time usage by performing necessary verifications in an efficient order rather than simultaneously or in reverse sequence.
3Reliability
If code reading and verification are performed for every supplied part, then parts supply errors are prevented, but the operation complexity and processing time increase
Solution Approach 1:
The manual or simple mechanical part verification process is replaced with an automated code reading and verification system. The code reader automatically scans part codes, and the system automatically compares them against recipe requirements through two determination steps. This substitution of automated information processing for manual verification maintains high reliability while reducing operation complexity and preserving assembly speed.

AI summary
Proposed is an apparatus and a method for preventing parts supply errors. The method includes inputting a recipe for a battery module into assembly equipment, supplying a part to the assembly equipment, reading a code displayed on the part supplied to the assembly equipment, determining, by the assembly equipment in the first determination step, whether the recipe stored in the assembly equipment matches the supplied part on the basis of the read code, determining, by an equipment management system in the second determination step, whether a recipe stored in the equipment management system matches the supplied part on the basis of the read code, and stopping operation of the assembly equipment and outputting an alarm when at least one result of the first determination step or the second determination step comes out as mismatch.
