Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery production, errors in reported station registration information due to abnormal physical or network addresses of code scanning devices lead to inaccuracies in process information transmission.
Innovation Solution
A material management method involving a code scanning system with blocking devices that control code scanning devices to block identifications at designated positions, allowing for detection of abnormal binding relationships between scanning devices and stations, and issuing alarms for timely correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If code scanning devices are used to register and report battery station information, then traceability of battery information is improved, but errors in station registration information occur due to abnormal physical or network addresses
Solution Approach 1:
The patent applies preliminary action by introducing a blocking device that physically blocks the code scanning device during the registration process. This blocking mechanism prevents the code scanning device from reading incorrect station information, thereby ensuring that only accurate information is transmitted to the upper computer. The blocking device is controlled to block or unblock based on the registration status, proactively preventing errors before they occur.
2Loss of information
If blocking devices are introduced to control code scanning devices, then accuracy of information transmission is improved, but device complexity increases
Solution Approach 1:
The patent merges the blocking device with the existing code scanning system architecture. The blocking device is integrated into the production line infrastructure and shares control logic with the code scanning device. This merging approach allows the blocking function to be added without creating a completely separate system, thereby reducing the overall complexity increase while still achieving accurate information transmission.
3Reliability
If blocking devices are controlled to work in first working state to block identifications, then detection of abnormal binding relationships is improved, but production line efficiency decreases
Solution Approach 1:
The blocking device operates periodically rather than continuously. It switches between the first working state (blocking) and second working state (unblocking) based on the registration process requirements. During normal production, the blocking device remains in the unblocking state to maintain efficiency. It temporarily switches to the blocking state only when registration or detection operations are required, thereby minimizing the impact on production line efficiency while still achieving reliable detection of abnormal binding relationships.

AI summary
A material management method applied to a battery production line includes controlling, after a plurality of battery cells placed on a plurality of stations reach designated code scanning positions, a plurality of blocking devices to work in a first working state according to a predetermined sequence, thereby blocking identifications of the battery cells on the corresponding stations, acquiring code scanning results of a plurality of code scanning devices corresponding to the blocking devices for the identifications, respectively, when the blocking devices work in the first working state, and determining, according to the code scanning results, whether a binding relationship between the code scanning devices and the stations is abnormal.
