Tray Traceability

1. Function Overview

Tray Traceability is part of the Basic Traceability module in the MES system's Data Middle Platform. It uses Tray ID as the entry point to query the circulation records of trays in various production batches, as well as detailed information of all batteries in the tray and the process flow timeline, enabling complete traceability from tray to battery.

Core Features:

• Tray Traceability Query: Query all production batch records associated with a tray by tray ID
• Battery Details View: Display detailed data of all batteries in the tray in a drawer panel within tray details
• Process Timeline: Display circulation records of the tray between processes in timeline form
• Deactivate Batteries: Support batch deactivation of battery active status in tray details
• Traceability Jump: Support direct jump from battery barcode in tray details to battery traceability page

2. Term Definitions

Term	Definition	Description
Tray Traceability	Tray Traceability, tracking batch circulation and battery details with tray as entry point	Part of Basic Traceability module in Data Middle Platform
Tray ID	Tray ID, unique identifier for trays in the system	Entry condition for traceability query
Login Batch	Production batch number, current production batch associated with the tray	A tray can be used in multiple batches
Lot Number	Lot Number, serial number of the tray within the batch	Used with batch to distinguish different trays in the same batch
Active Status	Active Status, indicating whether tray/battery is currently active	Active means production operations can continue; deactivated means no operations allowed
Input Battery Count	Input Battery Count, actual number of batteries loaded in the tray	Different from planned input quantity
Process Timeline	Process Timeline, time records of tray circulation between processes	Records start time, end time, and processing equipment for each process
Category/Grade	Grade classification determined after battery sorting process	Such as Grade A, Grade B, etc.
Battery ID	Battery ID, unique identifier for individual batteries in the system	Clickable to jump to battery traceability page for complete traceability information

3. Tray Traceability Query

3.1 Query Condition Description

Tray traceability uses tray ID as the only query condition, supporting exact match query.

Query Conditions:

Query Condition	Description	Required
Tray ID	Enter the tray ID to trace	Yes

[Note] You can jump to this page from other pages (such as Tray Management page) with tray ID parameter, and the system will automatically fill in the ID and execute the query.

3.2 Query Result Field Description

Query results are displayed at the tray level, where each record represents the circulation of the tray in a production batch.

Field	Description
ID	Unique identifier for tray circulation record
Tray	Tray ID
Login Batch	Production batch number associated with the tray
Lot Number	Serial number of the tray within this batch
Active Status	Current active status of the tray ("Active" or "Stopped")
Input Battery Count	Actual number of batteries loaded in the tray
Login Time	Time when the tray logged into this batch
Deactivation Time	Time when the tray was deactivated (if deactivated)

3.3 Query Operation Steps

1. Navigate to [Data Middle Platform] → [Basic Traceability] → [Tray Traceability]
2. Enter tray ID in the search box
3. Click [Query] button, the system displays all batch records associated with the tray
4. To clear query results, click [Reset] button

4. Battery Details View

4.1 Function Description

After finding the target tray through tray traceability query, you can view detailed information of all batteries in the tray. The system opens a full-width drawer panel, showing process timeline on the left and battery details table on the right.

4.2 Battery Details Table Fields

Field	Description
No.	Sequence number of battery in the tray
Battery ID	Unique identifier of battery, clickable to jump to battery traceability page
Production Batch	Production batch number to which the battery belongs
Model	Product model of the battery
Process Flow Name	Process flow name associated with this batch
Tray ID	Tray ID
Lot Number	Serial number of the tray within the batch
Active Status	Current active status of the battery ("Active" or "Inactive")
Category	Sorting category of the battery
Grade	Sorting grade level of the battery

4.3 Process Timeline

On the left side of the battery details drawer, the circulation records of the tray between processes are displayed in timeline form, intuitively reflecting the production progress of the tray.

Timeline Fields:

Field	Description
Process Name	Process name of this circulation record
Start Time	Time when entering this process
End Time	Time when leaving this process
Device Code	Code of equipment processing this process

4.4 Battery ID Search

In the battery details panel, front-end filtering by battery ID is supported to quickly locate the target battery.

Operation Steps:

1. Open the battery details drawer
2. Enter battery ID in the search box above the battery details table
3. The system automatically filters and displays matching battery records

4.5 Operation Steps

1. In the tray traceability result list, find the target tray row
2. Click the [Battery Details] button in the operation column
3. The system opens a full-width drawer panel, showing process timeline on the left and battery details table on the right

5. Deactivate Batteries

5.1 Function Description

In tray details, batch selection and deactivation of batteries are supported. After deactivation, batteries can no longer perform production operations. When all batteries in a tray are deactivated, the tray itself will also be cascadingly deactivated.

5.2 Operation Steps

1. In the battery details drawer, check the batteries to be deactivated (multiple selection supported)
2. Click the [Deactivate Batteries] button above the table
3. The system batch updates the active status of selected batteries to "Inactive"
4. If all batteries under this tray have been deactivated, the tray active status automatically changes to "Stopped"

[Note] Deactivation operation cannot be undone, please proceed with caution.

6. Traceability Jump

In the battery details panel, clicking any battery ID can jump to the battery traceability page for that battery, viewing the complete production process from raw materials to finished products.

Operation Steps:

1. In the battery details table, click the battery ID of the target battery
2. The system carries the battery ID information and jumps to the battery traceability page
