Description

technical field [0001] The invention relates to lighter manufacturing technology, in particular to a lighter flame height automatic adjustment device. Background technique [0002] As a dangerous product, the flame height of the lighter is a necessary inspection item in the manufacturing process; if the flame height is too high or too low, the flame height may be adjusted by adjusting the adjusting nut on the lighter to make it reach Production standards or national standard requirements. At present, there are several detection methods for the flame height of lighters: (1) using a simple measuring device—a ruler as a benchmark, for manual visual comparison detection, this detection method is low in automation, low in efficiency, and labor intensive Large, long-term work may cause damage to the eyes; and there are many human factors, there are certain errors in the observation data, and the measurement accuracy is low; (2) the image method is used as the measurement method o...

At present, there are several detection methods for the flame height of lighters: (1) using a simple measuring device—a ruler as a benchmark, for manual visual comparison detection, this detection method is low in automation, low in efficiency, and labor intensive Large, long-term work may cause damage to the eyes; and there are many human factors, there are certain errors in the observation data, and the measurement accuracy is low; (2) the image method is used as the measurement method of the flame height, and the method used in this method is The image acquisition system has the defects of high cost and high requirements for the use environment; (3) the temperature distribution of the flame is converted into a voltage signal through a thermocouple, and then the voltage signal is converted by an analog-to-digital converter, and finally the temperature is converted by a microprocessor Calculate the flame height according to the mathematical model of the flame, and display it on the display after comparison

This method needs to sense the flame through the thermocouple, so it is necessary to design a complex circuit structure, and the detection is to measure the flame, which is greatly affected by the external environment, has high requirements for the detection environment, and requires frequent maintenance of the thermocouple for Prevents thermocouple sensitivity from degrading

In addition, after the flame height is measured by the above several measurement methods, lighters that do not meet the regulations are screened out, and then adjusted manually, without synchronous adjustment after detection, and repeated detection is still required after adjustment, which is inefficient
