Intelligent control method for hot-press molding defects of sheet material

Abstract

The invention discloses an intelligent control method for hot-press molding defects of a sheet material. The intelligent control method comprises the following steps: loading the sheet material onto a frame; primarily scanning, namely, acquiring data information of the sheet material by virtue of an infrared detector and an image scanner; electronically detecting the sheet material, namely, transmitting the data information detected by the infrared detector and image information acquired by the image scanner to a data and image processor, comparing the data information and image information with a preset control index; processing the defects, namely, if an unacceptable defect is discovered in the sheet material by virtue of the comparison, transmitting a signal to an automatic computer control system; adjusting equipment parameters, namely, determining, by the automatic computer control system, a processing scheme according to the received signal, and transmitting the determined processing scheme to an equipment controller; and qualifying the defect, namely, after the parameter is adjusted, carrying out the primary scanning, electronic detection, defect processing and equipment parameter adjustment for the hot-pressed sheet material again until the defect of the sheet material is qualified. By adopting the method, the defects of the hot-pressed sheet material can be rapidly detected and treated in real time, so that the defective percentage can be reduced.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to an intelligent control method for sheet hot-press forming defects. Background technique [0002] The traditional detection and control of sheet metal hot pressing are all manual methods, relying on experience to repair and control according to the degree of defect of the sheet. However, the naked eye identification has certain limitations, especially the multiple defects on the surface of the board, the size and shape of the defects vary greatly, and manual classification is difficult, so this detection and control method can no longer meet the requirements of rapid detection and continuous control in wood production. need. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art, and provide an intelligent control method for defects in plate hot-press forming that reduces defective ...
