Embodiment Construction

[0029] combine figure 1 As shown in the flow chart of the invention, the process of adopting the high-speed disordered capsule defect detection system of the present invention is as follows: first, the capsule is placed on the assembly line through the capsule grabbing bucket; then the capsule is transmitted to the image capture window through the transmission device to collect the original image; Then, the collected original image is used for defect identification; finally, the signal of whether there is a defect is sent to the rejecting device, and the defective capsule is removed from the conveyor belt.

[0030] 1. Transmission and vibration device:

[0031] The transmission device is a necessary link in the detection of capsules, and the detection objects are continuously and batch-transmitted to the detection window through the transmission device. At present, the main transmission device can be divided into two ways: orderly arrangement (capsules are transported by neat...

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...
