The Design of the Detonator Wick Resistance Auto-Stripping Detector

Abstract:

This paper introduces an online auto-monitoring instrument which can automatically slice the external insulation cover of the leading wire and accurately measure the wick resistance in the assembly line of the detonator wick resistance. With safety protection circuit, constant current source is employed to measure the resistance, endowing the design with high accuracy, safety protection features and high degree of automation. It is expected to change the traditional production process where manual work has been used to measure and collect statistics, hence could greatly improve labor productivity as well as product quality and produce favorable application and promotion value.
