Light detection machine foreign matter detection device and method

Abstract

The invention discloses a light detection machine foreign matter detection device, which comprises a light detection plate for holding bottle bodies, wherein the light detection plate is provided with more than one detection station; each detection station is provided with more than two groups of light detection camera groups near the bottle bodies on the light detection plate; and each light detection camera group respectively corresponds to one group of bottle bodies arranged at intervals. The invention also discloses a light detection machine foreign matter detection method, which comprises the following steps: dividing a plurality of detection stations along the light detection plate; on each detection station, shooting and detecting all bottle bodies which pass through the detection station once; arranging more than two groups of light detection camera groups near the bottle bodies on each detection station; and respectively shooting and detecting one group of bottle bodies distributed at intervals by each light detection camera group. The light detection machine foreign matter detection device has the advantages of simple and compact structure, long service life, low noise and the like.

Description

technical field [0001] The invention mainly relates to the field of pharmaceutical machinery and equipment, in particular to a foreign object detection device and a foreign object detection method of a 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 the principle of comparing images with computers to automatically and intelligently detect the quality of packaged liquid medicines. The detection accuracy and detection accuracy of the light inspection machine Efficiency is two important indicators to measure its comprehensive performance. In the existing light inspection machine, the medicine bottles will be sent to the light inspection board in turn. When a group of medicine bottles filled with liquid medicine are sent to the light inspection area on the light inspection board at a uniform speed, the The light inspection c...

Problems solved by technology

[0005] Therefore, in the existing light inspection machine, the light inspection camera is arranged outside the light inspection plate, and is far away from the inspected drug bottle. However, in the actual use process, it is found that the shooting accuracy of the light inspection camera drops rapidly and generates relatively large noise. , Through repeated test analysis, it is known that the cause of this problem is: the light inspection camera is separated from the medicine bottle by a certain distance, its radius of gyration is large, and its moment of inertia is large. The inertial force, and the light inspection camera is a precision instrument, under the influence of this long-term and frequent inertial force, its service life will inevitably be shortened
