A system and method for automatic inspection of injection syringes on the basis of machine vision. The system comprise a detection and control part, image shooting devices (32, 33), light sources (34, 35, 36, 37), a part that makes an injection syringe (28) and the image shooting devices (32, 33) rotate relative to each other, and a rejected-product removal part (38). By use of a method of rotating the injection syringe (28) and the image shooting devices (32, 33) relative to each other, a plurality of images is shot along the circumferential direction of the injection syringe (28) and are directly stored in a computer, the images are screened, processed and analyzed to implement automatic inspection of multiple quality and technical parameters of the syringe, and it is unnecessary to position the opening direction of the needle tip. Inspection parameters and precision can be set at any time, the system can automatically record classification and statistics of qualified products and rejected products for query, and the rejected products will be removed automatically. All the functions are completed at one work station, and inspection of syringes with needle tips on both ends can be implemented at the same time, thereby greatly improving the inspection efficiency and reliability of syringes, and providing extremely extensive application prospects and huge economic values. |
