AOI (machine vision) light source design and manufacturing

What are the lighting sources used in AOI and machine vision?

In automatic optical inspection (AOI) and mechanical vision systems, light source is the key factor in determining image quality. Through the design of highly stable, highly uniform, and highly contrasting dedicated light sources, image recognition rate, defect detection rate, and production quality stability can be greatly improved.

Our company is committed to the research and development and manufacturing of AOI / mechanical vision light sources, and our services cover various industries such as semiconductors, PCB, TFT-LCD, electronic assembly, automation equipment, precision parts inspection, medical image processing and smart manufacturing.

AOI / Machine Vision Light Source Technology Development Focus

  1. Light pattern design and uniformity control
According to the surface structure, reflection characteristics and image requirements of the detected object, we optimize the design for the following light types:

  • Coaxial light, ring light, backlight, strip light, surface light source, oblique light, multi-angle light source
  • Using optical simulation software for light distribution design
  • Ensure illumination uniformity of more than 95%, eliminating shadows and hot spots
  1. High stability drive circuit design
  • Constant current drive and low noise control IC are used to ensure the brightness stability of the light source is better than ±1%
  • Equipped with overvoltage protection and thermal protection mechanisms to improve durability and safety
  • Multiple modes can be selected, including PWM dimming, external triggering or synchronous control
  1. Multi-wavelength/multi-spectral design
  • Available in red, blue, green, white, ultraviolet, infrared and dual wavelength combinations
  • Combined with image processing software algorithms, it improves defect separation and contour enhancement capabilities
  • Suitable for transparent object detection, reflective surface, package defects, IC pins, etc.
                 4.Heat dissipation structure and life control

  • Adopt high thermal conductivity aluminum substrate and special heat dissipation structure design
  • Passed high temperature aging test and life simulation test, the life span can reach more than 40,000 hours
  • Ensure that the light color and illumination remain stable under long-term use
