2. Working Principle

The Battery Stacking Machine operates on a series of automated steps that involve the following key processes:

2.1 Feeding and Alignment

Battery cells are fed into the machine through a dedicated inlet system. Precision alignment mechanisms ensure that each cell is oriented correctly for stacking.

2.2 Picking and Placement

A robotic arm or similar mechanism is used to pick up individual battery cells from the feeding system. The arm then precisely places the cells onto a conveyor belt or stacking platform, following a predetermined pattern or sequence.

2.3 Stacking and Compression

As the battery cells are stacked, compression mechanisms may be applied to ensure tight packing and reduce the risk of cell movement during subsequent operations.

2.4 Electrode Connection (Optional)

For battery packs that require electrode connections, the machine may include a welding or crimping station to connect the electrodes of adjacent cells.

2.5 Quality Inspection

Completed battery packs undergo a thorough quality inspection process, including visual checks and possibly electronic testing, to ensure that they meet the required specifications.

2.6 Output and Packaging

Finally, the battery packs are conveyed to an output station for further processing or packaging. Depending on the production line, they may be automatically packaged or prepared for manual packaging.
