AI Technical Summary
When existing auxiliary measuring fixtures fix the lens tubes with adhesive, uneven adhesive layer thickness makes it difficult to guarantee the parallelism and perpendicularity of the lens tubes, affecting the accuracy of measurement data. Furthermore, the inconsistent fixing intervals of multiple lens tubes affect measurement efficiency.
An auxiliary measuring fixture was designed, which uses a groove on the main body of the fixture and an internal air suction channel to fix the lens barrel using the principle of negative pressure adsorption. The negative pressure generated by the air extraction device is used to fix the lens barrel, ensuring stability and consistency.
It improves the stability of the measurement process, reduces detection errors, avoids data inaccuracies caused by glue or double-sided tape fixing methods, and improves the fixation stability of the microscope tube and measurement efficiency.
