所有锂离子电池制造商都需要高性能的电池电极作为其产品的构造模块。涂层阴极和阳极电极材料必须按照严格的标准制造,才能满足严格的能量性能、密度和存储要求。圆柱形、袋式和棱柱形电池中使用的涂层电极片必须在辊压阶段后进行涂层质量检查。工作的清洁状态和运动状态的变化会产生不同的缺陷,包括:

  • 脱碳
  • Bubbling
  • Craters
  • Holes
  • Dark points
  • Air bubbles
  • Tape splicing

Automated inspections with machine vision help standardize quality and ensure continuous, even coating. Cognex Industrial Line Scan Cameras (CIC) in line scan formats are ideal for “web” surface inspections to ensure that the film substrate is coated evenly with copper and aluminum. With line scan imagers available from 500 to 8000 pixels per line—and some even able to match high speed line acquisition rates of 67,000 lines per second—the latest generation of line scan cameras generate all the power necessary for applications that formerly required a cluster of high-resolution vision imagers. These attributes make line scan cameras an excellent choice for capturing target objects in continuous or discrete web inspections on fast-moving production lines.
