On-line vision detection device for visible foreign matters on transparent bottle appearance and in liquid

Abstract

The invention discloses an on-line vision detection device for visible foreign matters on transparent bottle appearance and in liquid. A rack, a camera bracket and a servo motor are all arranged on a base, a detection table is arranged on the rack, the servo motor is connected with a rubber tray used for holding a detected object via a belt transmission mechanism, a pressure lever mechanism with a pressure lever shaft is vertically arranged on the rack, a rubber contact at the lower end of the pressure lever shaft presses the upper end of the detected object, a CCD camera is arranged on the camera bracket, the lens of the CCD camera and the objected object are at the same height, the bottom of the rubber tray and the monitor station are at the same height, a backlight source is arranged on the detection table for providing backlight for the detected object, and a bottom light source is arranged below the detection table for providing backlight for the bottom of the detected object. The invention is an automatic detection device with simple structure, wide application range and high automation and functional integrated level.

Description

technical field [0001] The invention relates to an online visual inspection device for the appearance of transparent bottles and visible foreign matter in liquids, which is used for the detection of foreign matter impurities contained in oral liquids, medical vials and ampoules, as well as the appearance of the bottles and the filling capacity. technical background [0002] According to the survey conducted by the China Pharmaceutical Equipment Industry Association, the light inspection technology related to the clarity inspection process in my country's pharmaceutical industry is still mainly in the stage of manual visual inspection. The semi-automatic detection method that uses optical lens to magnify the foreign matter in the liquid medicine, then observes it with human eyes and rejects it manually, the defect of manual detection lies in 1) the detection accuracy is low, the detection quality is affected by human factors, and the error and false detection rate are high; 2) ...

[0002] According to the survey conducted by the China Pharmaceutical Equipment Industry Association, the light inspection technology related to the clarity inspection process in my country's pharmaceutical industry is still mainly in the stage of manual visual inspection. The semi-automatic detection method that uses optical lens to magnify the foreign matter in the liquid medicine, then observes it with human eyes and rejects it manually, the defect of manual detection lies in 1) the detection accuracy is low, the detection quality is affected by human factors, and the error and false detection rate are high; 2) The labor intensity of workers is high and the working environment is poor; 3) Human resources are wasted, which cannot meet the current industrial modernization management requirements

With the development of science and technology, scientific research institutes at home and abroad have developed pharmaceutical light inspection equipment with a high degree of automation. However, while improving efficiency, there are defects such as complex structure and high cost.
