Width Detection

Category：Width Detection

Abstract：A and B plane misalignment detection system uses the principle of image acquisition of linear array camera to online detect the width of A/B surface coating film, AT9 width and lateral misalignment width of A/B surface AT9 in continuous coating process.

Detailed Description

• Measuring principle：

  

  According to different measured material width and detection accuracy, one or more CCDs are selected for width measurement, and the linear array CCD camera is used as a sensor to simultaneously measure the two edge positions of the material to obtain a digital signal. Calculate the edge signal by processing to obtain the material width and give it to the user;

  
  

  H: According to the detection width and precision design, and increase the distance from the bottom surface of the material to the surface of the light source, the H1 material can be detected by two cameras with a particularly wide width.

  
  

  W: Design according to the maximum material width AB, and reserve the detection margin of J. The dead zone W between the two cameras is a fixed value

  Slitting machine width closed loop application:

  

  
  

  
  

  
  

  As shown in the figure cloth, during the cutting process of the coil material, the material will be deflected left and right when the material enters the slitting due to factors such as equipment tension, installation accuracy, material shape and other variables, and finally the material has a width error. Reduces the dimensional stability of the material.

  
  

          KADO designs a reliable DF Web guiding systems framework to control the position of materials entering the cutting station in real time. slitting CCD measures the width of the material and feeds the width deviation to Web guiding systems to correct the material Feeding position.
