Automatic quality inspection device for infusion set semi-permeable membrane based on visual recognition technology

Abstract

The invention discloses an automatic quality inspection device for a semipermeable membrane of an infusion set, comprising: a turntable detection platform, on which a glass turntable capable of rotating around itself is arranged; the turntable detection platform includes a feeding area, a detection area and Sorting area, the loading area includes the limit baffle set above the glass turntable, the paddle to be inspected and the photoelectric switch positioner below the glass turntable, the infusion set to be tested is guided to the detection The inspection area includes an industrial camera located under the glass turntable. The industrial camera collects images of the infusion sets entering the inspection area, and sends the collected images to the quality inspection system of the device for automatic defect inspection; sorting The area includes a sorting paddle set above the glass turntable and two unloading chutes on the edge of the glass turntable. The quality inspection system guides the infusion set to the corresponding unloading chute through the sorting paddle according to the quality inspection results. Among them, the present invention realizes the automatic quality inspection of the infusion set.

Description

technical field [0001] The invention relates to the technical field of medical product quality inspection, in particular to a semi-permeable membrane automatic quality inspection device for infusion sets based on visual recognition technology. Background technique [0002] The infusion set filter is an essential part of the infusion set used to filter the particles in the liquid medicine. Among them, the most important part of the filter is the semi-permeable membrane in the filter sheet of the infusion set. The semi-permeable membrane is attached to the liquid outlet of the infusion set through a welding process. The semi-permeable membrane allows liquid molecules to pass through in one direction, thereby filtering the drug particles. Therefore, the quality of the semipermeable membrane of the infusion set directly affects the purity of the drug delivered by the infusion set. If the semipermeable membrane has defects such as scratches, damages, and poor welding, the part...

AI Technical Summary

Problems solved by technology

[0005] First, the testing standards vary from person to person, and the test results are not objective and scientific enough;

[0006] Second, due to the small size of the semi-permeable membrane itself, the defects existing on the semi-permeable membrane are smaller, and the inspector may not be able to guarantee the reliability of the test due to visual fatigue;

[0007] Third, the manual detection method is time-consuming and inefficient;

[0008] Fourth, the manual inspection link cannot be integrated with the infusion set processing and manufacturing link, and the degree of automation is low
