E-Cigarette Atomizer Inspection
E-Cigarette Atomizer Temperature Rise Process Research & Development Inspection
◆ Requirement Background:
The core component of an e-cigarette is the heating element inside the atomizer. It heats rapidly, atomizing the e-liquid into vapor. Therefore, the temperature rise of the heating element directly affects the taste of the e-cigarette. To achieve optimal taste, manufacturers must ensure that the temperature rise process of each heating element is standardized and consistent.
◆Process Requirements:
1. During R&D testing, users need to measure the resistance-temperature relationship of the heating element and control the resistance change to ensure that the temperature rise process of the e-cigarette closely matches that of a standard source.
2. During production inspection, users need to verify the temperature rise of each heating element, checking the highest and lowest temperature points, heating uniformity, and temperature rise consistency.
◆Current Scenario:
The temperature rise of the heating element is monitored using contact temperature sensors, infrared spot thermometers, and other methods.
◆ Scenario Pain Points:
Contact temperature sensors:
- Sparsely distributed, unable to provide comprehensive temperature analysis, prone to missed detection points;
- Slow sensor response when the temperature of a heating element changes rapidly.
Infrared spot thermometers:
- Single-point temperature measurement, unable to provide overall temperature analysis and automatically identify the highest and lowest temperature points;
- Unable to detect small targets, especially heating wires measuring millimeters or smaller.
R&D Testing:
Intuitive Visualization, Accurate Temperature Measurement of Small Targets
During the R&D testing phase of heating elements, based on the principles of infrared thermal imaging, the system can intuitively and accurately detect temperature changes on small targets, such as heating elements and reference sources, assisting R&D in calibrating the resistance-temperature relationship of heating elements.
Chip heating element temperature detection
◆Test Target: Chip-type heating element
◆Test Requirement: Display the location and value of the highest temperature.
◆Situation Analysis: As can be seen from the thermal image, the red cursor position shows the highest temperature of 244.8°C. This is only 2mm away from the white cursor position, but there is a 3.5°C temperature difference. Using a temperature sensor or a spot temperature gun would generally not be able to pinpoint the highest and lowest temperature points with such precision.
Production Inspection:
Wide viewing angle, fast response, and improved temperature quality inspection efficiency.
This device, integrated into the fixture, measures the temperature of e-cigarettes on the production line. A single infrared thermal imaging temperature measurement module can simultaneously verify the temperature uniformity and temperature rise consistency of multiple heating elements, automatically locate the highest and lowest temperatures, and quickly identify over-temperature and low-temperature anomalies, triggering alerts. This improves heating element quality inspection efficiency and assists in the classification of quality products.
