AI Technical Summary

Technical Problem

In the existing optical module test, the crimping method is inefficient, the pressure is unstable, the module is easily scratched, and the lifting and cooling efficiency is low, resulting in waste of costs.

Method used

The optical module is clamped simultaneously through the cylinder push plate and the block assembly, and the temperature control module is combined with the contact with the heat dissipation surface. The spring buffering force and limiting structure are used to protect the surface of the optical module to ensure flat crimping.

Benefits of technology

An efficient cooling process is achieved, protecting the surface of the optical module from scratches, reducing time and cost, and improving production efficiency.
