Paper defect detection system for medical test paper

Abstract

The invention discloses a paper defect detection system for medical test paper. The system comprises a microcontroller, and a visual detection module, an action labeling module and a man-machine interaction module separately connected to the microcontroller, wherein the visual detection module is primarily composed of an industrial camera, a visual processor, a light source and a display; the industrial camera is arranged above a paper conveyor belt, the lower side is irradiated through a mirror light source, and the industrial camera is connected to the visual processor through a parallel bus; the visual processor collects images and carries out algorithm processing to obtain a specific coordinate position of the paper defects and the position data is transferred to the microcontroller; the action labeling module is primarily composed of a servo driver, a frequency converter and a servo motor; the microcontroller acquires the coordinate position of the visual detection module for dataanalysis and coordinate conversion to control the servo motor to label the corresponding position. The system detects and labels special bright spot and dark spot paper special for the medical test paper material. The system is constructed by means of an industrial automatic platform, so that the system is relatively high in reliability and speed accuracy.

Description

technical field [0001] The invention relates to the field of medical test paper processing, in particular to a paper defect detection system for medical test paper. Background technique [0002] Medical test paper is to fix biochemical reagents on the test paper to test human biochemical substances such as blood, urine, and feces, and then conduct preliminary screening for certain diseases. Because of its simple operation, convenience, and certain accuracy, it is widely used less favored by consumers. Due to the particularity of the application of medical test paper, its quality requirements for paper are much higher than that of ordinary paper. Traditional medical test paper paper inspection is manual inspection. Visual inspection under strong light is not only inefficient but also seriously harmful to human vision. Therefore, the development of medical test paper disease detection system has high research value. [0003] The quality of the paper used in medical test pape...
