摘要
A machine vision based automatic needle cannula inspection system includes an inspection and control unit, image capture devices, light sources, a unit that makes the needle cannula and the image capture device(s) rotate relative to each other, and a rejected part removal unit. By means of rotating the needle cannula and image capture devices relatively, a plurality of images captured along the circumferential direction of the needle cannula are directly saved to a computer, the images are then screened, processed and analyzed to fulfill the automatic inspection of multiple quality and technical parameters of the needle cannula without the need to position the bevel area of cannula tip to a specific direction. Inspection parameters and accuracy can be set at any time, the system can automatically record classification and statistics of passed and rejected needle cannulae for query, and the rejected cannulae are removed automatically at next position. All the functions are completed at one work station, and needle cannula tips on both sides can be inspected simultaneously, if needed. Thereby the inspection efficiency and reliability are greatly improved, resulting in extremely extensive application prospects and huge economic values.
