Batch Tray

1. Function Overview

Batch Tray belongs to the core module of the MES system, used to manage the association relationship between production batches and trays, realizing logistics tracking and management of batches during production. Trays are production containers that carry materials, and batch tray management runs through the entire production logistics process.

Core Functions:

• Batch Tray Query: Query the association information between batches and trays
• Batch Tray Details: View detailed information of batch trays
• Batch Tracking: Track the flow status of batches on trays
• Unbind Operation: Unbind the association between batches and trays
• Stop Operation: Stop the current status of batch trays

2. Term Explanation

Term	Definition	Description
Batch Tray	Batch Tray, association record between batch and tray	Records the tray information where batch goods are located
Tray	Tray, container for carrying materials	Used for material storage and flow
Tray Activation Status	Tray Activation Status, whether the tray is activated	Records the activation status of the tray
Tray Number	Tray Number, unique identifier of the tray	Each tray has a unique number
Batch Number	Batch, unique identifier of the batch	Used to trace product production information
Unbind	Unbind, release the association between batch and tray	Executed when materials leave the tray
Stop	Stop, stop the current status of the batch tray	Pause further flow of the batch

3. Data Model Relationship Explanation

3.1 Batch Tray Battery Hierarchy Relationship

Batch serves as the top-level entity, processes represent production stages. Some processes require trays to carry batteries, while in some processes, batteries exist independently after unbinding.

Relationship Explanation:

Relationship Type	Description
Batch → Process	1:N: A batch can contain multiple processes
Process → Tray	1:N: A process can contain multiple trays (Process 1 has trays)
Tray → Battery	1:N: A tray can contain multiple batteries
Process → Battery	1:N: A process can directly contain multiple batteries (Process 2 has no tray)

3.2 Battery Tray Binding Methods

There are two ways to bind batteries and trays, both can bind batteries and trays and log them to the batch:

Binding Method	Interface	Battery Status Requirement	Description
Binding Interface	set_tray_binding	Battery must be activated	Battery needs to be in activated state and belong to the same batch as the tray
Login Interface	set_tray_login	Battery does not need to be activated	Battery does not need to be in activated state, can be bound and logged to the batch

4. Batch Tray Interaction Flow

4.1 Batch Tray List

4.1.1 Batch Tray List Description

The batch tray list displays all association information between batches and trays, supporting query and filtering by multiple conditions.

Function Screenshot:

Figure 1: Batch Tray Page

Field Description:

Field	Description
Tray Number	Unique identification code of the tray
Serial Number	Serial number of the batch tray, used to uniquely identify each binding
Tray Status	Current tray status
Batch Number	Associated batch number
Process Flow Name	Associated process flow name
Current Process	Current process where the tray is located
Loaded Battery Quantity	Current quantity of batteries loaded on the tray
Login Time	Batch tray login time

4.1.2 Batch Tray Query

Query Conditions:

Query Condition	Description
Tray Number	Query by tray number exactly
Batch Number	Query by batch number exactly
Tray Activation Status	Filter by status (Activated, Stopped)
Login Time	Filter by creation time range

4.3 Unbind Operation

4.3.1 Unbind Description

Release the association between batch and tray. After unbinding, the tray status will become stopped, but the battery status will not change.

Operation Steps:

1. Go to [Production Configuration] → [Batch Management] → [Batch Tray]
2. Find the batch tray record to unbind in the list
3. Click [Unbind] button
4. Click [OK] to complete the unbind operation

[Important] The unbind operation is irreversible. Please confirm before executing.

4.4 Stop Operation

4.4.1 Stop Description

Stop the activation status of the tray and battery, pause further flow of the tray, used to handle abnormal situations.

Operation Steps:

1. Go to [Production Configuration] → [Batch Management] → [Batch Tray]
2. Find the batch tray record to stop in the list
3. Click [Stop] button
4. Click [OK] to complete the stop operation

[Important] The stop operation is irreversible. Please confirm before executing.
