  • Method and apparatus for controlling jet dispensing by displacement measurement
    Patent number: 10933436
    Abstract: A method for jetting a viscous medium onto a substrate is disclosed. The method includes providing viscous medium to a jetting chamber of an ejector, operating an impacting device to impact a volume of the viscous medium in the chamber such that viscous medium is jetted through a nozzle, connected to the chamber, towards the substrate, and monitoring a displacement of the impacting device during impact. An ejector and a system comprising such an ejector and a control unit is also disclosed. The monitoring of the displacement allows for the operation of the impacting device to be controlled accordingly, thereby providing for an improved control of the jetting process.

  • Jetting devices with control valve-enabled variable air flow and methods of controlling air flow
    Patent number: 10609822
    Abstract: A jetting device may include a vacuum nozzle configured to direct a gaseous flow of a gaseous fluid in flow communication with a jetting outlet; a vacuum pump configured to draw the gaseous flow into the vacuum nozzle and further towards the vacuum pump via the vacuum nozzle outlet; and an inlet conduit between a vacuum nozzle inlet and the ambient environment, where the inlet conduit includes a control valve configured to control a flow rate of the gaseous flow through the vacuum nozzle outlet based on adjusting a smallest diameter of the inlet conduit between an open diameter and a constricted diameter. The open diameter may be greater than a smallest diameter of the suction hole. The gaseous flow may include a first gaseous flow into the vacuum nozzle via a suction hole and an adjustable second gaseous flow into the vacuum nozzle via the vacuum nozzle inlet.
