The main purpose of a conduct cavity, core product residues confirmed two before closing the mold, the slider position, the top of the return location and other locations to confirm three, four confirmed plug insertion error, the top five out of a small break to confirm whether the detection products lack of material or burrs produce six, to check whether the product is missing more than seven points, check whether the correct multicolor product blending eight nine consecutive prevent defective products, reduce excess motion vision processors thimble set grabbers and vision processors processor in one. When the computer is slow in the past, the use of visual processors to speed up visual processing tasks. Since the acquisition cards can quickly transfer images to the memory mold protection alarm, but also much faster computer, so the visual processors use less of. 4 machine selection editing machine vision system, get a high-quality image can be processed is crucial. The system has been successful, we must first ensure good image quality mold, mold protection characteristics significantly infrared. A machine vision projects fail in most cases is due to poor image quality, features obvious cause. To ensure a good image, we must choose a suitable light source.
