A kind of manufacturing method of delaying body of electronic detonator

Abstract

The invention provides a manufacturing method of an electronic detonator delay element. The electronic detonator delay element comprises an electronic delay circuit board provided with a fuse head and a detonator wire connection hole, the fuse head with bent pins, a detonator wire and a special welding and locating tool. The method includes the steps that the electronic delay circuit board provided with the fuse head and the detonator wire connection hole at bonding pads at the two ends is placed in a welding and fixing tool; then, the fuse head with the bent pins and the detonator wire are inserted into connection holes of the electronic delay circuit board respectively; the fuse head is fixed by a fixing groove in the fixing tool, a fixing groove in the other edge of the fixing tool or a detonator wire pressing strip is used to fix the detonator wire, and the fuse head and the detonator wire are welded through a robot or manual work. The method improves working efficiency, better guarantees the welding quality of the delay element, and improves the quality of electronic detonator products. The manufacturing method is simple, the cost is low and the use effect is good.

Description

technical field [0001] The invention belongs to the field of blasting (F42D) electric ignition device (F42D1 / 045), in particular to a method for manufacturing an electronic detonator delay body. Background technique [0002] The production of the electronic detonator includes the manufacture of the delay body and the assembly of the detonator. The production of the delay body of the electronic detonator must first complete the manufacture of the electronic delay circuit board, and then weld the ignition powder and the detonator leg to the electronic delay circuit board. The electronic detonator delay body produced by the traditional process has a flat pad on the electronic delay circuit board, and the solder pins of the drug head and the detonator leg are linear. At present, when the industry produces the electronic detonator delay body, the drug head and the detonator are The welding of the foot wire basically adopts manual positioning and manual welding, and the welding of...

AI Technical Summary

Problems solved by technology

This traditional manual production method is backward in technology, low in production efficiency, and has inaccurate welding positioning. During the welding process, there may also be virtual welding and missing welding, which cannot ensure the welding of the drug head and the detonator leg. Reliability, the tensile strength of the welding part is poor; the manual welding method is also likely to cause improper welding of the ignition powder, and the ignition powder cannot be aligned with the fire transmission hole of the detonator during assembly, resulting in misfiring of the detonator

These have greatly affected the quality of electronic detonators, and it is also difficult to meet the needs of mass production
