DISPENSER AND METHOD OF DISPENSING AND CONTROLLING WITH A FLOW METER

摘要

A non-contact jetting dispenser, viscous fluid dispensing system and method. The system includes a viscous fluid dispenser for dispensing the viscous fluid. The system further includes a viscous fluid supply container adapted to hold the viscous fluid. A flow path is provided for the viscous fluid between the viscous fluid supply container and an outlet of the viscous fluid dispenser. An electronic flow meter device is used to produce electrical output signals proportional to the flow rate of the fluid flowing through the flow path. A control is operatively coupled to the electronic flow meter for continuously receiving and processing the electrical output signals and performing a responsive control function in a closed loop manner.

1. A non-contact jetting dispenser system including a jetting dispenser having a viscous material inlet and a viscous material outlet, the jetting dispenser being operable to start and stop the flow of viscous fluid from the viscous material outlet onto a substrate, the non-contact jetting dispenser system further comprising:
a viscous fluid supply container adapted to hold the viscous fluid, and coupled in fluid communication with the viscous material inlet of the jetting dispenser to establish a flow path for the viscous fluid between the viscous fluid supply container and the viscous material outlet of the jetting dispenser; and an electronic flow meter operatively coupled in the flow path to produce electrical output signals proportional to the flow rate of the viscous fluid flowing through the flow path when the viscous fluid is jetted from the viscous material outlet.
