Patent number: 9863755Abstract: Apparatus and methods of determining a position of a height sensor in a dispensing system. The dispensing system includes a dispenser, height sensor, camera, and a calibration device configured to receive a signal from the height sensor. The calibration device may include an optical sensor that generates an alignment signal in response to receiving light from the height sensor and/or a fiducial that causes the height sensor to generate the alignment signal in response to a detected height change. The alignment signal is used to automatically determine the position at which the height sensor is aligned with the calibration device. The position of the height sensor relative to a camera is determined by aligning the camera with the calibration device and recording its position. The recorded coordinates of the camera are compared to the coordinates of the height sensor when the height sensor is automatically aligned with the calibration device.Type: GrantFiled: October 29, 2014Date of Patent: January 9, 2018Assignee: Nordson CorporationInventors: Floriana Suriawidjaja, Todd S.

Publication number: 20170232465Abstract: A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots are controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.Type: ApplicationFiled: April 28, 2017Publication date: August 17, 2017Inventors: Ron Abernathy, Alec J. Babiarz, Nicholas Anthony Barendt, Robert Ciardella, James Everett Cooper, Kenneth S. Espenschied, Erik Fiske, Christopher L. Giusti, Patrick R.

Patent number: 6173864Abstract: A system for accurately dispensing controlled amounts of viscous material. The system includes a pressurized supply of the viscous material, a dispenser connected with the pressurized supply and a feedback control for ensuring that a discrete dispensed amount corresponds closely to the desired dispensed amount for a particular application. The different methods of feedback control include changing pressure of the pressurized supply after measuring a dispensed amount and comparing the dispensed amount with a stored value representing the desired amount. Another manner of feedback control includes changing an air operating pressure associated with the dispenser. A third type of feedback control includes adjusting the duration that the dispenser is maintained on to dispense the viscous material. Each of these types of feedback control are preferably used in succession, as necessary, to ensure that the desired amount of viscous material is discharged from the dispenser.Type: GrantFiled: April 23, 1999Date of Patent: January 16, 2001Assignee: Nordson CorporationInventors: Michael A.
