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

Abstract

The present invention is computer vision detecting device and method for real-time on-line detection based on the characteristics of article. The device consists of one capsule arranging and conveying unit, one computer vision recognizing unit and one capsule eliminating unit; and features the computer vision recognizing unit with CCD camera mounted over the capsule arranging and conveying unit and the capsule eliminating unit mounted beside the conveying chain of the capsule arranging and conveying unit. The capsule arranging and conveying unit includes one vibrating feeder and one conveying chain mainly; the capsule eliminating unit eliminating soft capsules in unqualified weight and shape consists of air source, solenoid valve and nozzle connected successively; and the computer vision recognizing unit consists of video camera system, lighting box, photoelectronic sensor, control module and corresponding software.

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 substance, it can also save technical treatment such as absorption and curing, which can effectively prevent the oily drug from seeping through the absorption excipients. Therefore, soft capsules are the most suitable dosage form for oily drugs. In addition, low melti...

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)
