Industrial Motherboard Based on X86 Architecture in Solar Cells Defect Inspection Solution

JHC Product News

The upstream of the solar industry chain includes crystalline silicon material, silicon rod, silicon ingot, silicon slice, the midstream includes solar cell production, PV module production, and the downstream includes the installation and service of photovoltaic systems and application products.

Avoiding product defects is an important part of product assurance in mass production.

In the solar industry, the efficiency and durability of the production and inspection of solar cells are critical for the development of the solar industry. Traditional manual inspection is relatively slow, subjective, costly and dependent on the operator’s experience. So, AI-based automatic visual inspection is needed as never before. As a vital component of the PV system, the automatic visual inspection of solar cells is significant. And today, Let's learn about JHCTECH's solution of defect inspection in solar cells based on the X86 architecture motherboard.

The Basic Visual Inspection System includes:

✔ Main Controller X86 Industrial PC；

✔ CameraLink video capture card

✔ DIO control card

✔ Optical Acquisition Sensor—Array CCD camera

✔ Light Controller；

✔ PLC, Servo drive and motor；

✔ Rejection Device

✔ Smart Vision System Software

The main controller commands the PLC to turn on the servo drive → turn on and adjust the light source → trigger the camera to take pictures → (Array CCD camera) to capture the image → transmit to the video capture card → the smart vision system software in the main controller make identification and judgment →The DIO control card sends feedback to the rejection device → finally the main control informs the PLC to stop the servo drive and turn off the light source, and finishes the detection process. In order to improve the detection accuracy and reduce the processing difficulty of the software, digital light source equipment should be used as an auxiliary.
