Research And Design The System Of Number Identification And Surface Defects For The Hot-Rolled-Billet

Billet number plays an important role in the production process as the identity identification of hot rolled billet.Billet quality directly affects and determines the quality of subsequent products.Therefore,the detection of hot rolled billet defects and identification of billet number play an important role in the billet production process.At present,the traditional manual record number and sampling quality testing methods of steel mills have been unable to meet the actual production needs.Therefore,this paper studies the identification and surface defect detection system of hot rolled billet based on ABB robot.In this thesis,ABB robot,CCD camera,sensor and other hardware equipment are constructed,and digital image processing technology is used to study and design the number identification and surface defect detection system of hot-rolled billet.The functions of number identification and surface defect detection of hot rolled billet are realized.The serial number and surface defect image collection of hot-rolled billet are realized by CCD camera installed on ABB robot,and the movement trajectory of the robot is controlled by software programming to achieve the billet multi-angle shooting and image collection.Using Open CV as the image processing software,preprocess the collected image information,including image noise reduction,locking the billet area and extracting the billet end face image;According to the optical features of the billet image,the gray histogram of the image was counted,and the threshold value was divided.The extracted billet image features were identified and judged.Considering the high temperature in the hot-rolled billet production process,this paper USES Fluent to analyze the high temperature field.Through establishing the system model,the analysis results show that the distance between the robot front end and the hot-rolled billet is 0.12 m,which is the best.The protective cover can effectively reduce the influence of temperature on the robot and ensure the normal operation.ABB robot based hot rolled billet number identification and surface defect detection system can accurately identify the billet number information,rapid detection of billet surface cracks,scratches,oxide layer defects,improve the production efficiency and intelligent manufacturing and management level of enterprises.
