High-speed unordered capsule defect detecting system

Abstract

The invention discloses a high-speed unordered capsule defect detecting system, which comprises a capsule transmitting device, an image collecting system, a defect identifying system and DSP (Digital Signal Processor) system transplantation, wherein the capsule transmitting device adopts a mode that capsules are randomly arranged and transmitted and is provided with a shaking device in front of a transmission belt; the image collecting system adopts the high-speed shutter technology of an industrial camera of 90 frames per second to solve the problem of smearing and adopts an infrared filter and a lens used for filtering infrared rays as double lenses to solve the switching problem of different detecting light sources; and the defect identifying system uses a method for setting a dynamic gray threshold to separate a foreground from a background and adopts a method based on the threshold to extract the edges of undivided unordered capsules. The defect detecting system adopts a machine vision technology to detect the shape and appearance of solid capsules and does not need contact the detected articles, so the system belongs to non-contact detection. The defect detecting system solves the problem of secondary pollution of the detected capsules under the general technology. The defect detecting system is an environment-friendly detecting system, and the detecting efficiency and precision and the degree of automation are high.

Description

technical field [0001] The invention relates to the field of drug detection, in particular to a high-speed disordered capsule defect detection system. Background technique [0002] Capsule defect detection is an important link in the field of pharmaceutical production, which provides an important guarantee for the safe production and use of pharmaceuticals. At present, domestic drug quality and appearance inspection methods mainly rely on naked eye recognition, and manual repeated selection is the main means to ensure quality. The number of employees who pick capsules often accounts for 1 / 3 of the total number of employees in the entire capsule factory. In foreign countries, there are relatively mature capsule testing systems and equipment, such as the SORTOMAT 8D testing machine from MASCHINPEX, Germany. However, there is no direct supply to the domestic market. Only pharmaceutical factories invested by foreign capital in China can import equipment from overseas with origi...

AI Technical Summary

Problems solved by technology

But there is no direct supply to the domestic market. Only pharmaceutical factories invested by foreign capital in China can import equipment from overseas with original packaging, but the technical details are strictly kept secret from the outside world.

Moreover, most of the existing equipment detects the ordered capsules that have been sorted. There are two problems with this ordered detection equipment: first, the detection throughput is small

Second, it is necessary to add an additional capsule sorting mechanism, which increases the cost
