Abstract

The invention discloses a flat knitting machine insertion piece detection method using a machine vision technology, and the method comprises the steps: carrying out an automatic program on a to-be-detected flat knitting machine insertion piece through a feeding station, and completing the feeding operation of the to-be-detected insertion piece; the method comprises the following steps: collecting the surface of a flat knitting machine insert to be detected in real time through a visual detection station, and then designing a digital image processing algorithm, including camera calibration and workpiece identification and positioning; thickness information of the insertion piece of the flat knitting machine to be detected is collected through a laser correlation sensor of the thickness detection station 3, and then identification of thickness defects is completed. The identified inserting pieces pass through a good product and defective product sorting station, the detected inserting pieces are discharged and placed through the good product and defective product sorting station, and discharging and conveying of the detected inserting pieces of the flat knitting machine can be achieved through a discharging station. According to the invention, the workpiece is automatically positioned and identified, the traditional manual detection is improved, and the insertion piece detection efficiency of the flat knitting machine is improved.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a method for detecting inserts of a textile flat knitting machine using machine vision technology. Background technique [0002] The quality of the inserts of the textile flat knitting machine has a great influence on the performance and quality of the final product. With the development of the times, the quality requirements of various businesses for the inserts of textile flat knitting machines are also constantly improving, and the competition in the industry is becoming increasingly fierce. For iron and steel enterprises, in order to ensure the production quality of inserts for textile flat knitting machines, it is essential to improve the quality inspection level. In the traditional inspection method for inserting defects of textile flat knitting machines, manual visual inspection is an effective method, but the labor intensity is high, and the production environment...
