[0002] Cardboard is also called board paper. It is a thick paper sheet made of various pulps and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard is defined as paper with a basis weight of more than 250g / m2 and a thickness of more than 0.5mm, and paper with a thickness of more than 0.1mm is generally defined as cardboard. Generally, paper with a basis weight of less than 250g / m2 is considered paper, and paper with a basis weight of 250g / m2 or more is considered cardboard. Cardboard is the main raw material for producing cartons. After the production of cardboard is completed, it needs to be inspected and sorted to remove products with unqualified sizes and select qualified products to improve the quality of the finished cardboard. The existing cardboard inspection and waste removal process is mostly manual inspection and waste removal, which has low efficiency and accuracy, and high labor intensity. [Summary of the invention]
