Solution details

Increase in synchronised drive shafts

Achieve reduced stacking machine cycle time using the latest high-speed motion system (controller, network, servos).

  • 1 motion controller can support a maximum of 256 shafts.
  • PLC open FB standard ST programme
  • Supports safe PLC and OPC UA safe communication.

Speeding up stacking operation and improving separator tension fluctuation

Use an electronic cam to control the separator feed to match the left-right movement of the stacking table. Stabilising separator feed operation will enable reduced cycle time.

Cam pattern can be automatically generated by inputting equipment dimensions using dedicated stacker Function Block.

Correction of position errors between separators and electrodes

Electrode position data detected by vision systems from various companies is read by the motion system via general-purpose Ethernet, enabling high-speed alignment correction to target position.

Our controllers can be easily connected to vision systems from various companies.
