Abstract

The invention discloses a micro-electro-mechanical system intelligent security explosion initiation device and a preparation method thereof. The micro-electro-mechanical system intelligent security explosion initiation device comprises an explosion initiation system and a packaging shell. The packaging shell is arranged on the outer side of the explosion initiation system in a cladding manner to package the explosion initiation system. The explosion initiation system comprises a micro explosion initiation chip unit, a micro security unit, an initiation chemical and a contact pin. The micro explosion initiation chip unit and the micro security unit are connected through the contact pin to form an electric signal channel. The micro explosion initiation chip unit is arranged below the micro security unit. The initiation chemical is installed on the back side of the micro explosion initiation chip unit. Because a micro explosion initiation and explosion propagation sequence based on an in-situ micro chemical loading technology, and the micro security chip based on the MEMS technology are adopted, and a technology of ultra-thin flattening chip inlaid design is adopted, the micro-electro-mechanical system intelligent security explosion initiation device has the characteristics of being micro, intelligent, and resistant to overload and electromagnetic interference.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a micro-electromechanical intelligent safety detonation device and a preparation method thereof. Background technique [0002] Micro-electro-mechanical systems (MEMS, Micro-electro-mechanical systems) is an integrated system of mechanical structure and electronic equipment at the micron level. Through the combination of mechanical, electrical, thermal, optical and other multi-physical field devices, it can not only perceive and process information , can also control the system through the action of the mechanical mechanism, and at the same time reduce the size and weight of the system structure, which is very suitable for mass production and one-time application of blasting products. At present, the commonly used detonation system is mainly manufactured by precision machining, which is difficult to process and assemble, and is bulky, which is not conducive to the anti-overlo...
