The detection device comprises a base, a main shaft, a turn plate and a synchronous tracking image acquisition component, wherein the main shaft is fixed to the base; the synchronous tracking image acquisition component comprises a revolving arm, an image acquisition component and a backlight source; the revolving arm is connected to the main shaft; the image acquisition component and the backlight source are symmetrically arranged on both sides of a bottle body on the turn plate and are fixed to the revolving arm through supporting parts; the base is provided with a supporting bracket; the turn plate is supported above the supporting bracket and can rotate on the supporting bracket; the supporting bracket is provided with an accommodating cavity; and the image acquisition component or the backlight source is fixed to the revolving arm through the supporting part inserted into the accommodating cavity. The foreign matter detection device for the automatic lamp inspector has the advantages of simple and compact structure, low cost, stability, reliability and capability of enhancing foreign matter detection accuracy.

Description

technical field [0001] The invention mainly relates to the field of pharmaceutical machinery and equipment, in particular to an automatic light inspection machine. Background technique [0002] In the field of pharmaceutical machinery and equipment, the light inspection machine is a series of special equipment that uses optical imaging and computer image comparison principles to automatically and intelligently detect the quality of packaged liquid medicines. The computer analyzes the collected image data, judges the quality of the liquid medicine, draws a conclusion and directs the rejection swing arm mechanism on the light inspection machine to reject unqualified medicine bottles. [0003] In the existing automatic light inspection machine, the turntable is often fixedly connected to the pressure plate through several long and thin ribs, and the pressure plate is fixed on the main shaft. The backlight and the camera are respectively arranged on both sides of the bottle to ...

AI Technical Summary

Problems solved by technology

[0004] However, when detecting foreign objects on the bottle, the several slender ribs used to hang the turntable are located between the camera and the backlight and are close to the bottle, which will absorb part of the light and affect the intensity of the light irradiating the bottle. Or reflect the light and interfere with the light received by the bottle, which will affect the effect of foreign object detection
