Wire Cassette Buffering

Our cassette buffering module is based on CoreFlow PV (Pressure Vacuum) rails, with a patent pending glass edge lifting mechanism forcing the glass to “jump” over the gap between the rails. Glass loading and unloading is performed using a VPL (Vacuum Pre-Load) motion drive, enabling high acceleration regardless of substrate weight. VPL conveying provides the following key advantages:

  • Mountable in any location on the platform with various configurations
  • High acceleration with friction force control (~ 1m/sec²)
  • High process speed (1.5m/sec)
  • Minimal calibration requirements
  • No edge-impact with wheels during glass approach
  • No up-down motions for on/off switching
  • Minimal glass deformation (~0.1mm)
