Design And Development Of The Mold Monitoring System In Plastic Injection Industry

Since the 20th century, with the continuous improvement of computer technology and VLSI (very large scale integrated circuits) the continuous development, they have led to image processing and image recognition technologies continue to mature, tremendous achievements have been made both in theory and practical applications. automatic identification technology is also being widely used in many areas. Image is the basis of visual, visual perception is an important means of human beings, as automatic identification of image pattern recognition technology has been the rapid development of more than half a century. Now it has been widely used in aerospace, military and remote sensing technology, biomedical, medical health, industry and other fields. At the same time, with the information highway, the number of the emergence of a global village and the rapid development of Internet, digital image as a quick visual transfer vector is bound to become an important means of access to information and gradually to other areas of infiltration.Based on workflow research analysis of the mold monitoring system in plastic injection, to solve the application of the mold monitoring system in plastic injection, digital image acquisition, processing and pattern recognition are discussed. In the paper, the first error is allowed to that is set up in the collected standard image, and then production in the processing, the images be collected by video capture dynamic images will be processed with the median filter algorithm and keep down useful information of products, and then use adaptive threshold segmentation algorithm for image processing, finally, pattern matching will be analysis with the first error values set up to complete the whole process of automatic identification. At the same time, the relevant principles and technology of image acquisition, image processing and pattern recognition of principles and the relevant technology are also introduced in this paper. In the hardware, in order to avoid signal interference due to mutual attenuation of the scene, the resistance is added on the I/O circuit board. At the same time, in order to better drive the relay, current amplifier is added on the I/O circuit board to enhance the driving force of the relay and the stability of hardware devices.Finally, the mold monitoring system software and hardware are developed and designed by DELPHI, testing shows that not only the quality of products are improved, but also the utilization rate of injection molding machines is improved, to extend the life of the mold, to reduce the mold maintenance and repair costs, enhance business competitiveness in the market.
