Description

Liquid discharge control system and method of pneumatic dispenser {SYSTEM AND METHOD FOR CONTROLLING LIQUID DISCHARGING AMOUNT OF PNEUMATIC PRESSURE DISPENSER}

The present invention relates to a system for controlling the liquid discharge amount of a pneumatic dispenser, and more particularly, detects the external temperature of a syringe containing a liquid (eg, silicone, epoxy, resin, etc.), and based on the detected external temperature It relates to a liquid discharge amount control system and method of a pneumatic dispenser capable of automatically adjusting the liquid discharge amount of a syringe by doing so.

A pneumatic dispenser that discharges a certain amount of liquid (e.g., conductive adhesive, resin, UV resin, various pastes, etc.) by pneumatic pressure (air pressurization) supplies high-pressure air from an external gas source to a proportional control valve, pressure sensor, etc. By controlling the specified pressure through the pressure, the liquid contained in the syringe-shaped syringe is discharged to the outside.

The viscosity of the liquid contained in the syringe can change according to the change in external temperature. If the viscosity changes due to the change in external temperature, the amount of liquid discharged from the syringe nozzle (needle) changes when the same energy (pressure) is applied. The problem is that when the discharge operation proceeds, the empty space expands as much as the volume of the liquid decreases inside the syringe, causing a change in the discharge amount.

In this case, a user (or operator) has to perform manual work such as readjusting the liquid discharge amount using a scale to keep the liquid discharge amount constant, and this problem occurs in an automated process. It is acting as a factor in generating negative losses.
