Optical design system based on tablet visual inspection, shooting method and controller

Abstract

The invention discloses an optical design system based on tablet visual inspection, a shooting method and a controller, and relates to the technical field of tablets and tablet package defect detection and visual optical design. Detection objects are tablets, a packaging substrate aluminum foil plate of the tablets and bubble caps wrapping the tablets. The optical design system based on tablet visual inspection further comprises a first lighting unit and a first shooting unit; a second lighting unit and a second shooting unit; a third lighting unit and a third shooting unit; a fourth lighting unit and a fourth shooting unit; a fifth lighting unit and a fifth shooting unit; and a control unit which is connected with the first lighting unit, the second lighting unit, the third lighting unit, the fourth lighting unit and the fifth lighting unit. According to the technical scheme disclosed by the invention, labor is saved, the labor intensity is reduced, and the maintenance cost and potential risks are reduced; and the shooting precision and the detection speed are improved.

Description

technical field [0001] The invention belongs to the technical field of tablet and its packaging defect detection and visual optical design, and in particular relates to an optical design system, lighting and shooting method and controller based on visual detection of tablets. Background technique [0002] At present, there are complex and multiple processes in the production and packaging process of tablets. Each process may produce corresponding types of defects in the process of production and transportation. Various types of defects may affect the appearance of the drug at least, and generally affect the safety of patients. , so it is very important for the quality inspection of tablets. [0003] However, manual or semi-automated detection is not conducive to improving detection efficiency and ensuring detection accuracy due to the uncertainty of personnel, and the existing optical solutions based on vision detection also have some limitations, such as: in the existing ta...

AI Technical Summary

Problems solved by technology

[0007] (1) In the prior art, the image information of each outer surface required for the quality inspection of the collected tablets is not comprehensive, resulting in a low detection rate of defects

[0008] (2) In the prior art, the tablet production line fails to realize the classification and elimination of defects

Cannot complete automatic image acquisition

[0009] (3) In the existing technology, the optical environment of the tablet cannot clearly reflect the obvious characteristics, resulting in a decrease in the detection accuracy of the later algorithm

[0012] (2) The existing technology fails to realize rapid elimination of stations, and classifies and eliminates product defects, which is convenient for providing reference for process optimization in the later stage
