AI Technical Summary

Technical Problem

In the prior art, the expansion coefficients of quartz microspheres and adhesive materials are different, which leads to the generation of local stress. Furthermore, the microspheres may flow away from the bonding position, affecting the control accuracy of the adhesive layer thickness and the bonding strength of the optical lens.

Method used

A device comprising a base, a slot, and a groove is designed. The base has a slot for positioning the lens mount, the lens mount has a protrusion for applying adhesive, and a needle gauge is placed in the groove to support the lens. The adhesive layer thickness is controlled by adjusting the dimensional relationship between the needle gauge and the protrusion to ensure the consistency of the adhesive layer thickness.

Benefits of technology

It achieves precise control of arbitrary adhesive layer thickness, avoids stress problems caused by differences in material expansion coefficients and microsphere flow, and improves bonding strength and surface accuracy.
