Abstract
The invention discloses a method and a device for detecting a structural shape of a semi-finished product of a detonator, and the method and the device can be used for automatically detecting the quality of the semi-finished product of the detonator in an online manner by using machine vision. The method comprises the following steps of: mounting the semi-finished product of the detonator inside a filling mould; sending the filling mould to a position under a telecentric lens through a conveyor belt; triggering a sensor of a control system and then controlling the system to send an instruction; irradiating a tube body of the detonator by using a coaxial parallel light source; shooting the detonator through the telecentric lens and an industrial camera; sending an image to an industrial computer; positioning and dividing the image through image processing software; and outputting position information of an unqualified product after the structural shape of each product is calculated and analyzed. The method and the device provided by the invention can be used for automatically detecting the structural shape of the semi-finished product of the detonator in an online manner and a machine vision system shooting manner, so that the influence of human factors on the product quality in human detection can be avoided; the direct contact of personnel and a hazardous article can be avoided; the production efficiency can be improved; the potential safety hazard can be removed; and the product detection quality can be ensured.
