This stack assembly machine is designed for the precise assembly of fuel cell stacks, flow battery stacks, and PEM electrolytic cells. It integrates a servo motor-driven high-precision ball screw and sensor system with a dedicated controller and advanced chip integration technology. A PCI-based data acquisition and control system enables full digital adjustment of test force, deformation amplification, and A/D conversion. The machine allows users to set key parameters such as packaging force and compression rate for the stack, and it also supports integrated air tightness testing. Developed by Canrd, this equipment is suited for research and small-scale production environments where repeatable, accurate stacking is critical for electrochemical device performance and durability.
