Liquid Dispensing Nozzle Inspection via Dynamic Droplet Timing

The patent applies dynamics by controlling the discharge timing of nozzles dynamically. Specifically, nozzles discharge liquid in sequential groups rather than simultaneously - first a first group of nozzles discharges, then a second group discharges after the first group's droplets are formed. This dynamic timing control prevents droplet coalescence while maintaining high productivity through rapid sequential dispensing.

The patent implements periodic action through cyclic discharge patterns. The liquid discharging apparatus operates in repeating cycles where nozzles are divided into multiple groups that discharge alternately. Each cycle includes discharging from the first group, forming droplets, then discharging from the second group, creating a periodic rhythm that ensures spatial separation of droplets while sustaining continuous high-speed operation.

The patent uses dynamics by adjusting the discharge amount based on the discharge timing of each nozzle group. The control unit calculates appropriate discharge amounts dynamically according to which nozzles are currently discharging and their spatial relationships. This allows larger discharge amounts for nozzles that discharge earlier, while later-discharging nozzles use smaller amounts, maintaining precision while improving overall efficiency.

The patent applies parameter changes by varying the discharge amount parameter for different nozzle groups based on their discharge sequence. The control unit modifies this critical parameter dynamically - increasing discharge amount for first-group nozzles that discharge earlier, and decreasing it for second-group nozzles that discharge later. This parameter optimization enables larger droplets without overlap, improving dispensing efficiency while maintaining placement precision.
