Description

Electrode plug manufacturing system and using method thereof Technical field

The present invention relates to the field of electric ignition tubes, and in particular to a system for manufacturing an electrode plug and a method of using the same.

Background technique

With the rapid development of the automotive industry, vehicle safety will be upgraded to a higher level and level, and higher quality requirements are imposed on the electric ignition tube of the core initial trigger component of the vehicle passive safety system. The core component of the electric ignition tube is an electrode plug welded with a bridge wire. The ignition components in the electric ignition tube for the airbag, the industrial electric detonator, the military electric ignition device, and the like are all electrode plugs welded with the bridge wire. In actual use, the electrode plug is connected with an external circuit, and is a core component of components such as a car airbag, an industrial electric detonator, and a military ignition device. The function of the electrode plug is to combine the functions of structural parts, fixed transducing elements, electrical insulation, airtightness, heat sinking, reflection ignition, etc., generally consisting of a bridge wire and two leg wires/electrodes. The bridge wire is a resistance wire welded to the two leg wires/electrodes. When the current passes, the bridge wire instantaneously heats up and heats the heat-sensitive ignition powder wrapped around the bridge wire when the temperature of the bridge wire reaches the point. After the ignition of the gunpowder, the ignition powder is ignited to achieve the function of the component.

As we all know, in order to reduce the casualties of car accidents, the car airbag needs to open the airbag within tens of milliseconds in the event of an accident. This requires that the bridge wire on the electrode plug is well welded and can instantly ignite the heat flammable wrapped on the bridge wire. Material (ignition medicine), the diameter of the general bridge wire is on the order of several tens of micrometers to ensure that the resistance is large enough to heat up quickly when energized, so that the small bridge ribbon has great welding difficulty. According to incomplete statistics, there are about 100 million electric ignition tubes for automobile airbags demanded by domestic automobiles. Due to technical limitations, only some American companies in the world have automatic mechanical welding bridge wire production lines, and the existing domestic electric ignition The pipes are basically hand-welded bridge wires. Most of the hand-welded bridge wires are brazed. The following disadvantages exist in manual welding: (1) the dispersion resistance of bridge wire resistance is greatly affected by human factors; (2) due to residual brazing The role of the agent, the dielectric joint and the electrochemical corrosion are present in the welded joint. The preferred corrosion sites of the two types of corrosion are the joints with the bridge wire. Therefore, the bridge of the electric detonator ignition device formed by the manual brazing process is used. The wire resistance value will increase irregularly during the storage period due to different corrosion rates. In severe cases, the electric detonator will be ignited. (3) Zinc chloride (ZnCl) or ammonium chloride (NH ₄ Cl) is present in the welding environment. Evaporation of harmful gases and heavy metal lead (Pb), etc., harms the environment; (4) Welding operations require high welder vision and damage, causing diseases such as electro-optic keratitis; (5) Low welding efficiency Labor-intensive, difficult to meet the market demand.

Under the above constraints, the current production of electric ignition tubes for domestic airbags is only 3-4 million, which is completely unable to meet the market demand. Moreover, the electrode plug welding wire process of electric ignition tube is also widely used in industrial electric detonators, geological exploration source bombs, flood control and precipitation rockets, aircraft model launches, military rockets, military missiles, artillery shells, fireworks and firecrackers, etc. huge. The process bottleneck of domestic electric ignition tube production is mainly that the bridge wire welding and electrical performance test are basically manual operation, so a technology capable of automatically mechanically welding the bridge wire will be an urgent problem to be solved in the field of electric ignition tube.
