Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0018] Such as figure 1 as shown, figure 1 A schematic structural diagram of an embodiment of the present invention is shown. In this embodiment, the chip-type explosive foil assembly includes the explosive foil 1, the flyer 2 and the electrode 3, and the flyer is bonded to the explosive foil; the chip-based design idea is adopted, the explosive foil is a rectangle, and the explosive foil array is placed on the base. The sheet is formed, and the electrode is formed by stamping. The electrode is copper foil, which is welded on the explosion foil.

[0019] According to another embodiment of the present invention, a method for producing a chip-type explosive foil assembly is provided. The specific production steps are: the outer shape of the explosive foil is rectangular, and a copper film or copper film is evaporated or magnetron sputtered on a larger ceramic substrat...

Abstract

The invention discloses a chip type exploding foil component and a production method for the chip type exploding foil component. The chip type exploding foil component comprises exploding foils, flyers and electrodes, wherein the flyers are adhered to the exploding foils; the electrodes are welded on the exploding foils; the exploding foils are rectangular, are arranged on a substrate in an array, and are formed in a scribing way; the electrodes are punched copper foils; the flyers adopt thermoviscous polyimide thin films, and are manually adhered in batches; soldering tin is coated in batches by a small-sized hand-operated screen printer; the exploding foil component is automatically welded in batches in a programmed way by a pulse hot-pressing reflow soldering machine. The chip type exploding foil component belongs to an explosion part of an inline slapper initiator; due to the adoption of chip design, the exploding foil component is simple in structure and favorable for the popularization and application of a slapper detonator, and is suitable to be automatically produced in batches, and a product is high in quality consistency and production efficiency and low in cost.

Description

technical field [0001] The invention relates to a shock plate detonator, in particular to a chip-type explosive foil assembly and a production method thereof. Background technique [0002] The detonator is the main detonating material in blasting engineering. Its function is to generate detonating energy to detonate various explosives, detonating cords and detonating tubes. Detonators are divided into fire detonators and electric detonators. Explosive foil components for shock-disk detonators are generally manufactured in a single-piece manner, resulting in low production efficiency and high cost, which cannot meet the demand for large quantities, and restrict the popularization and application of shock-disk detonators. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides a chip-type explosive foil assembly suitable for mass production, automatic production, high production efficiency and low cost and a production meth...
