Semi-Automatic Heavy-Duty Prismatic Battery Pack Assembly Line
Key Process Stations & Workflow
● Automated Cell Sorting: 6+1 channel OCV and internal resistance testing sorts prismatic cells into OK and NG channels to support module consistency.
● Heavy-Duty Roller Conveyor: Motorized roller conveyor with reflow loop supports stable transfer of large and heavy ESS/EV battery modules.
● Stacking and Compression: Ergonomic human-machine operation allows operators to complete module placement, fixture operation, and pressing preparation.
● 1000W Fiber Laser Terminal Cleaning: Removes oxides, oil, and surface contaminants from battery terminals before busbar welding.
● CCD Vision Polarity Inspection: Checks polarity, supports visual coordinate addressing, and reduces the risk of polarity-related assembly errors.
● 6-Axis Robotic Busbar Laser Welding: Industrial robot and fiber laser welding system execute busbar welding with stable process repeatability.
● Data Traceability: Barcode-to-database mapping and MES integration support process record tracking and quality audit.

FAQ
Q1: Why use a heavy-duty roller conveyor instead of a belt conveyor?
A: Large-capacity prismatic battery modules are heavy and require stable support during transfer, positioning, inspection, and welding. A heavy-duty roller conveyor helps maintain load capacity, transfer stability, and positioning accuracy at key process stations.
Q2: Can this semi-automatic line be upgraded later?
A: Yes. The line can be designed with modular stations, allowing customers to add automation upgrades such as robotic loading, automatic busbar handling, additional inspection stations, or higher-level MES integration as production demand increases.
Q3: Is this line suitable for both 280Ah and 560Ah cells?
A: Yes, subject to detailed module drawings and fixture design. The line can be configured with modular fixtures and programmable welding recipes for different prismatic cell dimensions and module structures.
Q4: Does Styler support overseas installation and commissioning?
A: Yes. Styler can provide engineering documents, remote technical support, video diagnostics, and optional on-site installation, commissioning, and operator training according to project requirements.
