Fluoroplastic film defect on-line detecting control system based on process control machine

The invention relates to an online detection and control system of a material defect based on an industrial computer, including five modules: a production line lighting module (in the text, a fluorine plastic film is taken as an example) which is suitable for the strip-shaped material characteristics; a motion control module which conducts high-precision control to a step motor; a collecting and control module which drives a plurality of high-resolution linear arrays CCD to carry out synchronous collection; a detection processing module for carrying out an image recognition to the strip-shaped material defect; and a network monitoring module which is used for conducting real-time monitoring to a detection result panel in a factory network. The invention provides a step motor, a key technology of coordinative control of the image collection, and a key collection control technology of the synchronous collection of the plurality of high-resolution linear arrays CCD; and the invention has the advantages of fast s
