Abstract

A bridge wire welding system used for producing an electrode plug comprises a circulation track (20), a pushing device (21), positioning devices (4), and a welding device (5). An electrode plug base body moves along the circulation track (20) in a stepped manner by means of push of the pushing device (21). and the positioning devices (4) used for enabling a bridge wire (96) to precisely align to the a core electrode (90) are disposed at the upstream and the downstream of the welding device (5). Each positioning device (4) comprises a wire pressing wheel (40) and a force applying device (42), and the force applying device (42) drives the wire pressing wheel (40) to downwards move to tightly press the bridge wire (96). The welding device (5) comprises a driving device (52), a guide rod (53), and a welding head (54). The welding head (54) is clamped at the lower end of the guide rod (53). The driving device (52) drives the guide rod (53) and drives the welding head (54) to downwards move. By means of the bridge wire welding system, the bridge wire (96) can be automatic welded, and the production qualified rate of the electrode plug can be remarkably increased; and the bridge wire welding system is applicable to the technical fields of cars, industrial detonators, ignition appliances and the like.

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.

Abstract

Disclosed is an automatic glass-breaking emergency escape and alarm system. The system has: a glass-breaking apparatus (1) for breaking glass; an independent control apparatus (3) for receiving a signal and controlling the detonation of the glass-breaking apparatus (1), the independent control apparatus (3) being connected to the glass-breaking apparatus (1); and a centralized control apparatus (4) connected to a plurality of independent control apparatuses (3) via a communication bus (5) or conductive wire, the independent control apparatuses (3) and/or the centralized control apparatus (4) comprise a fault self-diagnosis system which can promptly perform fault diagnosis on an electric ignition loop. Also disclosed is a traffic vehicle having the system. The automatic glass-breaking emergency escape and alarm system can automatically sense the occurrence of an accident and can automatically break glass. The fault self-diagnosis system can promptly diagnose a circuit fault, so as to ensure that the system is in a working state at any time and has a high safety factor.
