Semi-Automatic 32140 & 33140 Cylindrical Battery Pack Assembly Line Solution

The cylindrical battery assembly line is designed for manufacturers producing battery packs for electric two-wheelers and three-wheelers, power tools, portable power stations, and other applications compatible with 32140 and 33140 cylindrical cells.

ACEY provides integrated semi-automatic battery pack assembly line solutions for manufacturers working with 32140 and 33140 cylindrical lithium-ion cells.

Rather than supplying a fixed equipment package, we help customers select and configure the machines according to their cell specifications, battery pack design, production targets, factory layout, and investment budget. This approach enables manufacturers to establish a practical production process while maintaining flexibility for future product development and capacity expansion.

Each stage serves a specific purpose in the production process. Equipment selection and process settings can be adapted to the customer's cell chemistry, pack configuration, interconnection design, and quality requirements.

The cell grading machine evaluates cell performance through controlled charge and discharge testing. Depending on the selected equipment, the system can record capacity, voltage, and other relevant test data for subsequent classification.

 

Grouping cells with compatible performance characteristics helps improve consistency within the assembled battery pack. Channel configuration, current range, and testing programs are selected according to the actual cell specifications and production requirements.

Insulation paper pasting machine  applies insulating paper to the specified terminal area before pack assembly.

 

Consistent insulation placement helps reduce the risk of unintended electrical contact during cell arrangement and pack assembly. Replaceable tooling can be configured for supported cell formats, including 32140 and 33140, subject to the selected machine design.

After insulation application, the battery cell sorting machine measures voltage and internal resistance and groups cells according to predefined acceptance criteria.

 

Consistent electrical characteristics are important for reducing cell-to-cell variation within a battery pack. Optional channel configurations and barcode scanning can be considered when production throughput and cell identification requirements justify them.

The CCD inspection system  uses industrial imaging to inspect designated cell features, including the positive and negative electrode areas.

 

Automated visual inspection helps identify specified appearance or positioning issues before cells enter the welding process. Inspection criteria should be defined according to the actual cell structure and quality-control requirements.

The battery pack spot welding machine is used to connect cylindrical cells with specified conductive connectors and interconnection materials, forming the required series-parallel configuration. ACEY can configure manual, single-side automatic, or double-side automatic spot welding equipment according to pack geometry, welding requirements, and production targets.

 

Welding parameters, electrode selection, fixture design, and monitoring requirements should be validated using the customer's actual cells and connecting materials. This helps establish repeatable welding quality and reduces the likelihood of missed or inconsistent welds.

The BMS tester machine evaluates the selected battery management system's supported functions during pack integration, depending on the customer's process design. Depending on the tester configuration, test items may include overvoltage and undervoltage protection, overcurrent protection, temperature protection, short-circuit protection, and cell-balancing functions.

 

The test program is selected according to the BMS hardware, communication protocol, protection thresholds, and battery pack specifications.

After assembly, the battery pack comprehensive testerchecks key electrical and protection characteristics against the defined acceptance criteria. Depending on the equipment configuration, test items may include open-circuit voltage, internal resistance, charge and discharge performance, protection response, and related electrical parameters.

 

This stage helps identify potential assembly or electrical issues before packaging and final release. Test limits and procedures should be established according to the battery pack design and applicable customer requirements.

The heat shrink packaging machine  applies and shrinks compatible insulating or protective film around the battery pack or its designated enclosure.

 

Film selection, tunnel temperature, conveyor speed, and packaging dimensions must be matched to the product structure and material specifications. A properly configured process helps achieve a neat, consistent package appearance.

The inkjet batch coding machine prints required identification information on the designated product surface or packaging.

 

Depending on the system configuration, the printed information may include model numbers, production dates, batch codes, serial numbers, or other identification fields. Coding supports product identification and production record management.

The battery aging machine subjects finished battery packs to defined operating conditions for a specified period or test cycle. Depending on the selected equipment, the process may monitor voltage, current, capacity-related parameters, and other configured test data.

Abnormal results can be reviewed against established acceptance limits before the products proceed to final inspection and shipment.

 

Test voltage, current, channel count, and aging procedures should be determined from the finished battery pack specifications.

No two battery pack projects are exactly alike. The appropriate equipment configuration depends on the relationship between the cell, pack design, required output, testing standards, and available factory resources.

ACEY works with customers to evaluate the following project details:

• Cell specifications: 32140 or 33140 cell dimensions, chemistry, nominal voltage, capacity, and relevant electrical characteristics.
• Battery pack design: Series-parallel configuration, pack dimensions, connecting materials, BMS requirements, and enclosure design.
• Target production capacity: Required output per shift or day, planned operating hours, and expected product mix.
• Factory conditions: Available floor space, operator workflow, power supply, and equipment arrangement.
• Investment and expansion plans: Preferred automation level, initial budget, and potential future capacity increases.

Based on these details, we can recommend an appropriate equipment combination and discuss the main process stages, machine specifications, and potential upgrade options.

ACEY provides battery pack assembly equipment and customized assembly line solutions to help customers develop a production setup aligned with their technical and commercial objectives.
