Automatic Vertical Grooving Machine for Cylindrical Battery Cells

1. Equipment Description

This equipment is engineered for the grooving process of rechargeable Ni-MH, Ni-Cd, and cylindrical lithium-ion batteries. The grooving machine employs a PLC, intermediate relays, and time relays to control the coordinated movements of each cylinder. A motor drives the machine body at high speed, executing uniform automatic grooving on cylindrical steel cans that hold cells.
