Online AOI 3D Automatic optical inspection Description

Features (Online AOI 3D Automatic optical inspection ):

Online AOI Dual Cameras Double-sides Inspection

Top and bottom double cameras, each has independent XY moving platform.

Top camera used to inspect insertion components, while bottom camera used to inspect wave soldering surface, two surface inspected simultaneously

  • 5 million pix full-color high speed digital camera (20 million pix optional), ensure high efficiency, high quality and high stability of image shooting, restore the real and natural image effect.
  • Lens resolution can be flexibly adjusted range from 10-25um to apply for different requirement.
  • Windows 7 x64 operation system,high data processing speed.
  • Thousands of sales, advanced and upgraded configuration and continuous technologicalinnovation based on 8 series AOI products, high stability and efficiency.
  • Optional telecentric lens with high resolution, unique parallel light design, PCBA tilted or tall components can be distinctly displayed.
  • Intelligent and fast programming,intelligent algorithm, no need of manual intervention, easy to learn, high detection rate, low error rate.
  • Flexible and mobile maintenancestation and SPC checking terminal.
  • Mobile devices under wireless network, working station can be set up flexibly on workshop in one to many mode: the detection data of multiple online machines can be checked through one maintenance workstation, the defect details are clearly reported. SQL data system are well-defined, SPC report with pie chat and histogram, very convenient for customer process analysis and quality improvement.
  • Convenient and practical offline programming software OLP.  PCB genuine image can be taken in real time and stored in full memory, ensure high efficient programming under circumstances of either online or offline.
  • Multi–angle ring power long-life high-brightness LED light source with excellent positioning capabilities; can be applied to a variety of circuit boards, including non-mark spots.
  • High precision and reliable mechanical and electrical system, X/Y driving system applied AC servo motor and high precision grinding ball screw with reliable performance.
  • PCB auto fixing, rapid and accurate positioning without manual operation, fast adjustment&visible operation.
  • Link to customer MES system
