Abstract
Assembly and quality of an electronic vaping device (“e-vaping device”) may be tested and verified using imaging techniques. Infrared (“IR”) imaging may identify whether a temperature is uniform in an vaping device during usage. Potential burning locations may be identified through the imaging by identifying locations whose temperature is unusually high or non-uniform. This temperature information may be used to calibrate the power of the e-vaping device.
Claims18
A method for quality control of an e-vaping device comprising:
- powering a heating coil of the e-vaping device;
- generating a thermal image of the heating coil that includes a representation of a temperature of the heating coil;
- analyzing the thermal image of the heating coil based on input conditions;
- and
- calibrating the e-vaping device based on the analysis of the thermal image of the heating coil.
2 more elements
An imaging system comprising:
- a sensor configured to generate a thermal image of at least a heating coil of a cartridge of an e-vaping device;
- and
- an analyzer coupled with the sensor and configured to identify temperature variations across the heating coil, and determine whether or not a temperature across the heating coil is uniform based on the identified temperature variations.
A method for e-vaping device production comprising:
- providing electric current to a coil in an e-vaping device cartridge;
- imaging a temperature throughout the coil;
- identifying a potential burning location based on the imaging;
- and
- calibrating the e-vaping device cartridge when the potential burning location is identified.
