A kind of manufacturing system of electrode plug and using method thereof

Abstract

Disclosed are an electrode plug manufacturing system and a use method therefor. The electrode plug manufacturing system comprises a supporting device (80), a tool circulation device (2), a bridge wire positioning device (4), a bridge wire welding device (5), a wire cutting device (6), a micro-tension wire feeding device (3), and a feeding device used for feeding an electrode plug base body into the tool circulation device. The tool circulation device comprises a circulation track (20) and a pushing device (22). A moving guide groove for a tool (23) is formed in the circulation track, and the pushing device pushes the tool to move in the circulation track. The bridge wire positioning device is disposed on the circulation track. The bridge wire welding device and the wire cutting device are disposed on the supporting device or the circulation track. The system can fully-automatically welds a bridge wire, and the welding efficiency is high.

Description

technical field [0001] The invention relates to the field of electric ignition tubes, in particular to an electrode plug manufacturing system and a using method thereof. Background technique [0002] With the rapid development of the automobile industry, automobile safety will be promoted to a higher level and level, which puts forward higher quality requirements for the electric ignition tube, the core initial trigger element of the automobile passive safety system. The core component of the electric ignition tube is the electrode plug welded with the bridge wire. The ignition parts in the electric ignition tubes for airbags, industrial electric detonators, and military electric igniters are electrode plugs welded with bridge wires. In actual use, the electrode plug is connected to the external circuit, and is the core component of components such as automobile airbags, industrial electric detonators, and military igniters. The function of the electrode plug is to have th...

AI Technical Summary

Problems solved by technology

According to incomplete statistics, the current domestic demand for automobile airbag electric ignition tubes is about 100 million. Due to technical limitations, only a few companies in the United States have automatic mechanical welding bridge wire production lines in the world. The tubes are basically hand-welded bridge wires, and most of the manual-welded bridge wires use brazing technology. Manual welding has the following disadvantages: (1) The dispersion of the resistance value of the bridge wires is greatly affected by human factors; (2) due to the residual brazing Due to the role of the agent, there are both medium corrosion and electrochemical corrosion in the welded joints. The preferred corrosion parts of these two types of corrosion are the parts that are connected to the bridge wire. Therefore, the bridge of the electric detonator ignition device formed by this manual brazing process The wire resistance value will increase irregularly due to different corrosion rates during the storage period, and in severe cases, it will cause the electric detonator to ignite and fail; (3) there is zinc chloride (ZnCl) or ammonium chloride (NH 4 Cl) The evaporation of harmful gases and heavy metal lead (Pb), etc., endangers the environment; (4) The welding operation method has high requirements on the welder's eyesight and great damage, which will cause diseases such as electro-optic keratitis; (5) The welding efficiency is very low, labor High strength, difficult to meet market demand

[0004] Due to the above constraints, the current domestic production of electric ignition tubes for automobile airbags is only about 30-40 million, which cannot meet the market demand at all.
