Battery Pack Laser Welding Machine - AGV

Battery PACK Laser Welding Machine

Engineered for inline integration in high-volume EV battery production lines, the Battery Pack Laser Welding Machine performs cell-to-busbar welding at the scale of a full battery pack. Multi-robot dynamic clamping, integrated 3D vision, and Dual-Source AI weld quality monitoring deliver high throughput and high first-pass yield on the most demanding battery designs.

Scalable from a fully enclosed Class-1 cell to an open-design configuration, the platform is unified under a single control software that manages clamping, vision, laser, and weld monitoring as one making it a complete inline solution ready for full-pack and cell-to-chassis production.

Battery Pack Laser Welding Machine - 8 robots

HIGH-THROUGHPUT MULTI-ROBOT CLAMPING

Up to 8 SCARA robots dynamically clamp each cell-to-busbar connection while the laser welds in parallel, keeping laser duty cycle high. Clamping tools provide force feedback and motorized angle adjustment. Optional second laser source on an independent gantry for increased throughput or full redundancy.

AI-POWERED IN-CYCLE WELD QUALITY

Our Dual-Source AI inspects every weld, identifies the defect type, and triggers automated rework inside the same station, in the same cycle. Photodiode emissions and HD images analyzed in real time, boosting first-pass yield and reducing scrap on high-value packs.

ADAPTABLE AND CONFIGURABLE

The platform scales to different battery module, pack, and cell formats. Available as a fully enclosed Class-1 safety cell or open-design configuration. Robot count is sized to your throughput target. Configurable part loading and laser monitoring options available.

UNIFIED CONTROL ARCHITECTURE

Clamping robots, vision, laser, and weld monitoring are managed within a single integrated control software. Built-in recipe manager, calibration routines, and MES communication accelerate deployment and simplif long-term support. A single point of accountability across the complete welding process.

Battery Welding Expertise

Our battery and laser welding experts are involved at every step of the project. They can optimize the laser welding performance for your specific application, support your product design phase from a laser welding perspective, assist in preproduction and testing phases, and build battery modules to test your process.

Data Monitoring for Weld Traceability

Detailed data of the welding process for each individual cell is recorded at all times, including temperature, clamping tools, clamping pressure, weld monitoring (LWM) data feedback, and so on. The monitored data is recorded and stored in the machine, and it is accessible to your MES system.

Complete Solution

Our experts look at your complete manufacturing process so that the machine includes everything you need to integrate laser welding in your production line. Accountable for everything, we’re with you every step of the way to make sure integration is a success and performance requirements are met.
