AI Technical Summary
Existing equipment cannot meet the requirements for switching and precise adjustment of lenses and light sources of different sizes, resulting in difficulties in verifying lens light sources and inaccurate accuracy.
A convenient and adjustable lens light source testing device was designed, including a lens clamping mechanism, a surface light moving mechanism, a glass platform mechanism, and a bottom light moving mechanism. The height of the lens and light source is adjusted by guide rails and lead screws, and precise control is achieved by photoelectric limit switches.
It enables fixed clamping and height adjustment of lenses of different sizes, ensuring precise adjustment of coaxial light source, ring light source and bottom light source, and improving the accuracy of test verification.
