Abstract: Systems and methods for inspecting and cleaning a nozzle of a dispenser are disclosed. The systems may include a platform supporting a cleaning substrate. The cleaning substrate may have a plurality of hook structures configured to remove a material from the nozzle. The systems may also include a camera configured to capture an image of the nozzle and a controller configured to control the system. The methods may include providing a cleaning substrate having a plurality of hook structures, and moving at least one of the nozzle and the cleaning substrate relative to the other to remove a material from the nozzle. The methods may also include capturing an image of the nozzle after dispensing with a camera, processing the image to generate a value, utilizing the value to determine if the nozzle should be cleaned, and if the determination is that the nozzle should be cleaned, cleaning the nozzle.

Abstract: Systems and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes calibrating flow rate of a material through a coating system. A target flow rate for the material through a spray nozzle is received, a first operating pressure of the coating system based upon the target flow rate is calculated, and the material is ejected onto a least part of a surface with the material flowing through the spray nozzle at the first operating pressure of the coating system. Subsequent to a comparison between an operating flow rate and the target flow rate, the operating pressure is adjusted to a second operating pressure and at least part of the substrate is sprayed with the material flowing through the spray nozzle at the second operating pressure of the coating system.

Abstract: Systems and methods for two-component mixing in a jetting dispenser are provided herein. A jetting dispenser includes a fluid chamber having a first fluid inlet providing a first fluid and a second fluid inlet providing a second fluid, wherein the first fluid and the second fluid mix within the fluid chamber into a mixed fluid. A method for dispensing a mixed fluid from a dispenser having a fluid chamber in fluid communication with first and second fluid inlets is also provided. A first fluid is provided to the fluid chamber via the first fluid inlet and a second fluid is provided to the fluid chamber via the second fluid inlet. At least a portion of a valve element is moved relative to a valve seat to cause dynamic mixing of the first fluid and the second fluid within the fluid chamber to produce the mixed fluid that is dispensed.

Abstract: A jet cartridge for jetting fluid material includes a body adapted to receive fluid material, and a fluid passage defined within the body and extending along a longitudinal axis thereof. At least a portion of the fluid passage extends obliquely relative to the longitudinal axis. The body is adapted to receive heat from a heating element and to transfer the heat to the fluid material flowing through the fluid passage. A method of jetting fluid material with a jet dispenser including a jet cartridge includes receiving fluid material into the jet cartridge, directing the fluid material through the jet cartridge along a longitudinal axis thereof and obliquely relative to the longitudinal axis, heating the fluid material directed through fluid cartridge to a target temperature, maintaining the target temperature as the fluid material enters a nozzle, and jetting the heated fluid material through the nozzle.

Abstract: Systems and methods for closed loop fluid velocity control for jetting are disclosed. A method includes dispensing a first volume of viscous fluid from a nozzle of a dispensing device according to a first value of an operating parameter that affects the exit velocity of the first volume. A characteristic of the first volume is measured using a sensor. The characteristic of the first volume is then compared to a range of values to determine whether the characteristic of the first volume is outside of the range. The value of the operating parameter is adjusted to a second value in response to determining that the characteristic of the first volume is outside the range. A second volume of viscous fluid is dispensed according to the second value of the operating parameter. The exit velocity of the second volume is different than the first volume.

Abstract: Methods and systems of accurately dispensing a viscous fluid onto a substrate. In an embodiment, a method includes using an electronic flow meter device to produce electrical flow meter output signals and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter to correct for a difference between an output data set and a reference data set. In another embodiment, a system includes a control operatively coupled to a gas flow meter device and to a weigh scale allowing for a density of an amount of viscous material to be determined. In another embodiment, a method includes using a control coupled to both a gas flow meter device and a weigh scale and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter using gas flow meter output signals and weigh scale output signals.

Abstract: Systems and methods for improved fluid dispensing process control using a machine learning tool are disclosed. In an example method, successive portions of viscous fluid are dispensed by a dispensing device according to operating parameters to train a machine learning tool to associate defect classifications with images of dispensed portions and/or operating parameters associated with dispensing the dispensed portions. The trained machine learning tool is then used in a closed loop fashion in production to detect and correct for defects associated with the dispensed portions to improve quality and production efficiency.
