Battery Spot Welding Machine Detailed Product Description
Product Overview – Double-Side Cylindrical Battery Spot Welder
PPCELL’s double-side cylindrical battery spot welding machine is purpose-built for high-volume series and parallel welding of cylindrical lithium-ion cells in battery pack assembly. Serving the lithium battery industry, this equipment processes 18650, 21700, 26650, 26700, 32700, and 32140 cylindrical cells for EV battery packs, e-bikes, power tools, and energy storage systems. The machine is used in the battery pack assembly process – specifically the cell interconnection stage before module assembly.
The system features a double-side simultaneous welding design that welds both sides of the cell in a single operation. Unlike traditional single-side welders, this approach significantly reduces welding time and ensures balanced heat distribution, minimizing deformation and improving weld consistency.
Key Features
Dual-Side Simultaneous Welding – Welds both positive and negative terminals simultaneously, eliminating the need for cell flipping and doubling production efficiency.
Fully Electric Operation – Servo motor-driven system eliminates the need for compressed air, avoiding welding inconsistencies caused by unstable air pressure.
High-Speed Production – 3600 cells/hour throughput (60 cells/min), maximizing production efficiency for high-volume battery pack assembly lines.
Precision Motion System – HIWIN brand guide rail modules deliver ±0.1mm XY axis welding accuracy with high precision, low noise, and smooth movement.
Intelligent Alarm & Repair System – Automatic alarm for false welding and poor-quality welds with manual area repair and single-point repair functions.
Flexible Programming Options – Supports manual programming and CAD drawing import for rapid welding path programming. Simple to learn – production line workers can operate with minimal training.
User-Friendly HMI – High-definition LCD touchscreen with interactive interface for easy operation and parameter adjustment.
Advanced Automation Features – Self-developed intelligent systems including energy switching, production counting, welding pin compensation, and manual debugging functions.
Through-Type Design – Supports both front-in/front-out and front-in/rear-out configurations for flexible production line integration.
Durable Construction – Aluminum alloy frame with imported acrylic protective panels provides full visibility for safe operation.
Optional Upgrades:
MES system real-time production statistics
Real-time pressure tracking system for weld quality monitoring
Multi-pulse or transistor welding power supply options
