摘要： Systems and methods for venting a solvent are disclosed. The system includes a chamber, such as an oven having an interior volume defining a heating zone, where the interior volume receives at least one substrate coated with a coating material comprising a solvent. The system further includes a vent coupled to the oven and defining a passage between the interior volume and the environment external to the oven. The system also includes a solvent sensor measuring an amount of evaporated solvent present in the interior volume, and a fan removing at least a portion of the solvent from the interior volume. The system may also include a coating assembly including an applicator and a flow meter, wherein the applicator applies a portion of the coating material to the substrate, and the flow meter determines the amount of coating material applied to the substrate.

摘要： 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.

摘要： System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.

摘要： Systems and methods for dispensing a liquid or viscous material onto a substrate are disclosed herein. One exemplary method of positioning an applicator of a dispensing system to apply a liquid or viscous material to an electronic substrate includes generating a two-dimensional image of the electronic substrate using a camera communicatively connected to the dispensing system. Based on the two-dimensional image of the electronic substrate, a first set of one or more sub-regions of the electronic substrate having one or more components that protrude above the surface of the electronic substrate is identified. The method further includes using height information relating to the one or more sub-regions having the one or more components to determine a control program for the dispensing system to position the applicator relative to the electronic substrate and dispense the liquid or viscous material onto the electronic substrate.

摘要： A fluid dispensing system and a method of controlling a fluid dispensing system are disclosed. The fluid dispensing system includes a source of a fluid, a dispensing nozzle, and a spray system. The spray system supplies fluid from the source of fluid to the dispensing nozzle using system parameters for the spray system. The spray system and dispensing nozzle are configured to dispense the fluid as a stream or spray as an actual fluid pattern according to one or more first system parameters that are intended to produce a first fluid pattern. A camera is configured to capture one or more images of the actual fluid pattern dispensed from the dispensing nozzle. A controller is operatively connected to the spray system and the camera.
