Abstract
Systems and methods are described herein for analyzing the application of adhesives. An adhesive comprising a fluorescent property is applied to a component. The component is illuminated using one or more of wavelengths of light from a light source, wherein the adhesive is configured to absorb the one or more wavelengths of light and fluoresce in response. An image of the component is captured using a camera while the component is illuminated using the light source. One or more fluorescence characteristics from the image are determined and a state of the applied adhesive is determined based on the one or more fluorescence characteristics.

A method for analyzing application of an adhesive, comprising:
- applying the adhesive comprising a fluorescent property to a component;
- illuminating the component using one or more of wavelengths of light from a light source, wherein the adhesive is configured to absorb the one or more wavelengths of light and fluoresce in response;
- capturing an image of the component using a camera while the component is illuminated using the light source;
- determining one or more fluorescence characteristics from the image by;
- determining a fluorescence shape in the image;
- comparing the determined fluorescence shape to an expected fluorescence shape in a sample image stored in storage, the expected fluorescence shape indicating expected dimensions of the adhesive;
- determining a fluorescence level based on the image;
- and
- determining a volume of the applied adhesive based on the determined fluorescence level;
- and
- determining a state of the applied adhesive based on the one or more fluorescence characteristics by:
- determining whether the determined fluorescence shape is substantially similar to the expected fluorescence shape based on the comparing;
- and
- determining whether the determined volume is within a desired range based on a volume threshold.
A system for analyzing an adhesive, comprising:
- an adhesive dispersal module, wherein the adhesive dispersal module contains the adhesive comprising a fluorescent property;
- a light source configured to emit one or more wavelengths of light, wherein the adhesive is configured to absorb the one or more wavelengths of light and fluoresce in response;
- a camera;
- and
- control circuitry configured to:
- cause the adhesive dispersal module to apply the adhesive to a component;
- cause the light source to illuminate the component with the one or more wavelengths of light;
- cause the camera to capture an image of the component while the component is illuminated using the light source;
- determine one or more fluorescence characteristics based on the image in a measurement unit by:
- determining a fluorescence shape in the image;
- comparing the determined fluorescence shape to an expected fluorescence shape in a sample image stored in storage, the expected fluorescence shape indicating expected dimensions of the adhesive;
- determining a fluorescence level based on the image;
- determining a volume of the applied adhesive based on the determined fluorescence level;
- and
- determine a state of the applied adhesive based on the one or more fluorescence characteristics by:
- determining whether the determined fluorescence shape is substantially similar to expected fluorescence shape based on the comparing;
- and
- determining whether the determined volume is within a desired range based on a volume threshold.
