The process of battery pack disassembly production line generally includes the following steps:

Preprocessing:

Information registration and testing: Register the information of the recycled battery packs, 

and record the basic information such as the source, model, and service life of the battery packs.

At the same time, use professional testing equipment to test the appearance, voltage,

 internal resistance and other parameters of the battery pack to determine the basic 

status of the battery pack and whether there are safety hazards, such as bulging, 

leakage, etc. For battery packs with safety risks, special marking and processing are required.

Discharge treatment: There may be residual electricity in the battery pack. 

To ensure the safety of the disassembly process, discharge treatment is required.

Usually, resistance discharge, constant current discharge and other 

methods are used to release the electricity in the battery 

pack to a safe level, and the voltage is generally required to drop to a lower safety value.

Shell disassembly:

Fixing and positioning: Fix the battery pack on the disassembly workbench 

and use a positioning device to ensure that the battery pack does not move during the disassembly process.

For some irregularly shaped battery packs, special clamps may be required to fix them 

so that subsequent disassembly operations can proceed smoothly.

Shell disassembly: According to the shell structure and connection method of the battery pack, 

select appropriate tools and methods to disassemble the shell.

For example, for a shell connected with screws, you can use tools 

such as an electric screwdriver to remove the screws;

For a shell connected with a buckle, you need to use a professional 

pry bar or other tools to carefully pry open the buckle.

During the disassembly process, be careful to avoid damage 

to the shell and internal battery components.

Module separation:

Internal structure observation and analysis: After opening the battery pack shell, 

observe the internal structure of the battery pack to understand the connection method and layout of the module.

This step is very important for the subsequent module separation work,

 and requires careful observation and analysis in order to formulate a reasonable separation plan.

Module disassembly: According to the observed module connection method, 

use the corresponding tools and equipment to disassemble the module.

If the modules are connected by welding, it may be necessary to use equipment 

such as laser cutting to separate them;

If they are connected by bolts, use tools such as wrenches to remove the bolts.

 During the disassembly process,

pay attention to protecting the integrity of the module to avoid damage 

to the battery cells inside the module.

Removing connecting parts: After the modules are separated, each module contains multiple battery cells. 

First, it is necessary to remove the connecting parts between the battery cells, such as connecting plates,

 wires, etc. These connecting parts may be connected by welding or plugging, and it is necessary 

to choose the appropriate method to remove them according to the specific situation.

 Removing the battery cell: Use professional tools, such as suction cups, clamps, etc.,

 to remove the battery cell from the module. During the removal process, be careful to 

avoid damage such as squeezing and collision to the battery cell, and prevent the battery cell from short circuiting.

Component classification and testing:

Component classification: The disassembled battery pack shell, module, battery 

cell and other components are classified and placed.

For recyclable components, such as battery cells, metal shells, etc., they should be stored separately;

For waste that cannot be recycled, such as insulating materials, glue, etc., 

they should be classified and processed in accordance with environmental protection requirements.

Component testing: Further testing of the removed battery cells, including testing of 

parameters such as voltage, capacity, internal resistance, and appearance inspection. 

According to the test results, the battery cells are divided into different categories such as reusable, 

repairable and scrapped, so as to carry out corresponding treatment

Safe handling and environmental protection measures:

Safe handling: During the entire disassembly process, safety operating procedures must be strictly

 followed to prevent safety accidents such as battery short circuit, fire, explosion, etc.

For sparks and static electricity generated during the disassembly process, 

appropriate protective measures must be taken, such as setting up anti-static 

equipment in the disassembly work area and equipping fire extinguishing equipment.

Environmental protection measures: Some waste and harmful substances, 

such as electrolytes and heavy metals, will be generated during the disassembly of the battery pack.

Appropriate environmental protection measures must be taken to collect, 

process and recycle these waste and harmful substances to prevent pollution to the environment.
