This paper aims to transform the ammunition packaging and marking production line, improve production efficiency, and realize the gradual iteration of the ammunition packaging and marking production line to automated production. The re-develop of AutoCAD was based on Python, and the automated program for the input of ammunition marking information was compiled, so that the ammunition product information could be directly generated into the two-dimensional drawings of the marking information. The system could realize the input of ammunition packaging information, marks, and automatically generate two-dimensional drawings of marking information, and quickly modify relevant information according to the actual needs to meet the needs of automatic production. The system optimizes the design process of ammunition packaging and marking, saves manpower and time costs, improves production efficiency, meets the needs of industrial automation production, and has certain practical application and reference value.
