Automatic basic detonator grain height detection and waste rejection device and method

Abstract

The invention relates to the technical field of basic detonators and discloses an automatic basic detonator grain height detection and waste rejection device, which comprises an anti-explosion chamber, a grain height detection system and a waste rejection device, wherein the anti-explosion chamber is used for transmitting a mold loaded with a plurality of detonators to an automatic mold transmission system in the anti-explosion chamber; the grain height detection system is arranged in the anti-explosion chamber and provided with a lifting cylinder and an optical fiber sensor connected with the lifting cylinder; the lifting cylinder and the optical fiber sensor are respectively connected with a computer outside the anti-explosion chamber through a programmable logic controller (PLC); and the waste rejection device is arranged in the anti-explosion chamber, connected with the computer through the PLC and used for rejecting detonators of which the heights are unqualified. The automatic basic detonator grain height detection and waste rejection device is high in production efficiency, can accurately detect the height, can avoid missed detection, and can realize safety production in a man and machine separating mode.

Description

technical field [0001] The invention relates to the technical field of basic detonator detection, in particular to a device and method for automatic detection and elimination of the height of a basic detonator powder column. Background technique [0002] The detonator is the main detonating material in a blasting project. Its function is to generate detonation energy to detonate various explosives, detonating cords and booster tubes. During the production process of detonators, various defects are often caused in the produced detonators due to factors such as inaccurate control of the charge amount of the delay charge or raw material defects. The common defects are: the total charge amount of the delay charge is more or less, The high or low column composed of delayed charge, and the lack of reinforcing caps, etc., will seriously affect the performance of the detonator, and even cause dangerous accidents. [0003] At present, the detection of detonator defects mainly relies...

Problems solved by technology

In the production process of detonators, various defects are often caused in the produced detonators due to factors such as inaccurate control of the charge amount of the delay charge or raw material defects. The common defects are: the total charge amount of the delay charge is more or less, Caused by high or low powder column composed of delayed powder, and lack of reinforcement cap, etc., these defects will seriously affect the performance of the detonator, and even cause dangerous accidents

[0003] At present, the detection of detonator defects mainly relies on manual detection, which has low detection efficiency and is often affected by human factors, which may easily cause misjudgment and missed judgment. In addition, there are not only safety hazards
