Equipment Inspection and Maintenance Q&A for Lithium-Ion Cell Manufacturing: Forms and Interactions

Data sources for this category include raw material batches, MES systems, slurry and coating testing equipment, dew point monitoring devices

What data for this category looks like

Data sources for this category include raw material batches, MES systems, slurry and coating testing equipment, dew point monitoring devices, formation and grading cabinets, and laboratory testing equipment. Data updates in real time per batch and per individual cell. Daily documents include batching records, coating and rolling parameters, winding or lamination records, liquid injection records, formation and grading data, and OCV and safety test reports. Fields cover slurry batch identifier, coating areal density, rolling gap value, dew point monitoring value, formation and grading voltage curve data, and OCV value. Corresponding units include batch number, g/㎡, mm, ℃, V, Ah, and others.

What constraints these characteristics impose on forms and interactions

Since data updates in real time per production batch and individual cell, forms must support associating multi-dimensional parameter fields by batch. This prevents duplicate data entry and data lag. Since daily documents are split into process and testing categories, interactions must support searching corresponding document fragments by category. This allows quick location of maintenance and inspection references. Since electrochemical systems have strict requirements for environmental parameters and parameter consistency, forms must include mandatory validation items such as dew point and cleanliness. This blocks entry of abnormal parameters. Since data sources cover production and testing systems, forms must support connecting to external data sources to automatically pull parameters. This reduces manual operation errors.

How to set configurations

Configuration ItemRecommended SettingRationale
formInputEnable field-level real-time validation. Mandatory fields include slurry batch and dew point valueCorresponding production data requires precise association with batches and environmental parameters to avoid invalid entry
userSelectPre-set four department options: electrode sheet, assembly, formation, qualityMatches the typical departmental division of labor for this category, enabling quick location of corresponding business scenarios
Form retrieval groupingDivide by process category and testing categoryMatches the characteristic that documents for this category are split into types such as batching, rolling, formation and grading
Abnormal value alert rulePop up an alert when dew point value exceeds -50℃~-10℃ or coating areal density exceeds 800~1200g/㎡Electrochemical systems have high requirements for parameter consistency, so abnormal parameters must be blocked in a timely manner
External data source connectionAutomatically pull coating and rolling parameters from the MES system from the past hourMatches the characteristic that this category's data sources include MES, reducing manual entry volume
Question matching thresholdCalibrate based on actual measurementsMust adapt to the retrieval and matching accuracy of multi-dimensional parameters for this category

Three common mistakes

  • Phenomenon: A "receiving message address verification failed" prompt pops up when configuring DingTalk integration. Cause: The FastGPT service is not exposed to the public network, and SSL certificate verification is not disabled or a valid certificate is not configured as required by the documentation.
  • Phenomenon: The formInput component does not enable real-time validation. No alert is triggered after entering abnormal slurry ratio parameters. Cause: The validation rules for the corresponding fields are not configured, leading to incorrect parameters flowing into the production ledger.
  • Phenomenon: The userSelect component does not pre-set department options. Engineers must manually enter department information. Cause: The typical departmental division of labor for this category is not matched, and the default options are not comprehensive enough.

How to confirm the configuration is complete

  • Open the scenario configuration page of FastGPT v4.17.0. Confirm that the formInput component has been set with mandatory fields such as slurry batch and dew point value, plus real-time validation rules.
  • Call the userSelect component. Check if the four pre-set department options (electrode sheet, assembly, formation, quality) are present.
  • Enter parameters that exceed the calibrated range. Check if the corresponding pop-up alert is triggered.
  • Conduct a DingTalk integration test. Confirm that messages can be sent and received normally, with no address verification error.
