Research on the application of charge height detection technology based on contour scanning in flash detonator production
TANG Zihan
Abstract：This paper introduces a method for measuring the charge height of flash detonator based on contour scanning technology,and investigates the effects of different tube lengths,different light source interferences,and reflective surfaces variations on the measurement accuracy of the system,with comparisons relative to manual measurement.The results show that the measurement accuracy of the charge height detection system is unaffected by tube length,with a maximum range of 0.54 mm for repeated measurements of the same sample.When the punch end face is subjected to stains,rusts,and wear,and the maximum variation of the measured values is 0.40 mm.When simulating external light interference,it causes irregular changes in the measurement error of the charge height detection system,with a maximum range of 0.59 mm.The experimental results show that the measurement error of the flash detonator charge height measurement system based on contour scanning technology is lower than that of the manual measurement,indicating that it meets the technical requirements of the detonator production online measurement process.
