Online detecting device and method based on computer vision for soft capsule quality

Abstract

The invention relates to a machine vision detection device and method for real-time online detection according to the characteristics of articles, which is composed of a capsule arrangement and delivery part, a computer vision recognition part and a capsule removal action part; its feature is that the camera of the computer vision recognition part is installed on Above the conveyor chain of the capsule array conveying part, the capsule rejecting action part is installed on the side of the conveyor chain of the capsule array conveying part. The capsule arrangement conveying part mainly includes a vibrating feeder and a conveying chain. The function of the capsule rejecting action part is to reject those soft capsules with unqualified weight and special shape, which is mainly composed of air source, solenoid valve and nozzle connected in sequence. The computer vision recognition part consists of a progressive scanning camera system, a light box, a photoelectric trigger sensor, a control module and corresponding software. The invention achieves the purpose of indirectly detecting the weight of the capsule through computer vision, and ensures the accuracy of high-speed online detection of the weight of the soft capsule.

Description

technical field [0001] The invention relates to a machine vision detection device and method for real-time online detection according to the characteristics of articles, in particular to a device and method for online detection of soft capsule quality based on computer vision. Background technique [0002] Soft capsule is a new dosage form developed after tablets and injections. It can quantitatively inject oily drugs, drug solutions or drug suspensions, pastes, and even drug powder into the film, forming a size and shape. Assorted sealed capsules. Compared with other dosage forms, it has the characteristics of high bioavailability, accurate content, good uniformity, and beautiful appearance; if it is an oily drug, it can also save technical treatment such as absorption and curing, which can effectively prevent the oily drug from seeping out from the absorption excipients Therefore, soft capsules are the most suitable dosage form for oily drugs. In addition, low melting po...

Problems solved by technology

This detection method not only has high labor intensity and high labor cost, but also cannot guarantee the accurate detection of the quality of all capsules due to the complexity of manual detection.

In addition, some existing capsule detection technologies, such as the related research patent "Capsule Automatic Online Weighing Detection Machine" (application number: 200420064679.2), are only suitable for on-line detection of hard capsules because they are based on a weighing principle.

And this method can't get rid of those irregular soft capsules (shaped pills)
