This machine is mainly used for Z-stacking of cell cathodes, anodes and separators. It adopts manipulators for automatic material picking, secondary positioning and stacking, as well as automatic separator feeding, deviation correction and constant tension control. The separator is automatically cut off, finished cells are unloaded by manipulators, and end tape is pasted manually. It delivers high stacking efficiency and precision, and compatible cell sizes can be switched via fixture adjustment.
Key Features
- Servo-driven automatic constant tension control for separator rolls, paired with automatic separator edge position correction
- Manipulator completes automatic material picking, secondary positioning and stacking, plus automatic separator drawing, deviation correction, constant tension regulation and separator cutting
- Finished cells are taken out by manipulators with manual tape pasting, ensuring high stacking efficiency
- Automatic stacking cycle count control based on preset values
- Versatile structural design; adjustable positioning fixtures support a wide range of cell dimensions
- Separated pressing claws for cathode and anode to prevent cross-contamination of positive and negative electrode materials
- PLC control system with HMI touchscreen for convenient operation and maintenance
