AI Technical Summary

Technical Problem

In the traditional laser engraving process for silver jewelry, the extremely high thermal conductivity of silver causes heat to spread rapidly, which can easily lead to melting, collapse, and molten splashing during processing, affecting the precision of the process.

Method used

A laser engraving device for silver jewelry surface was designed, comprising a processing platform, motion components, laser processing components, support frame, fixed housing, guide tube, and cooling mechanism. Cold air is generated by a cooling fan and directed to the surface of the silver jewelry through the guide tube to keep it cool and prevent melting and collapse caused by excessive heat.

Benefits of technology

This effectively prevents silver jewelry from melting and collapsing due to excessive local heat during laser engraving, improving processing precision and stability, and ensuring the clarity of the engraved pattern.

Abstract

This utility model relates to the field of silver jewelry processing, specifically to a laser engraving device for the surface of silver jewelry. The device comprises a processing platform, a motion component, a laser processing component, a support frame, a fixed outer shell, a guide tube, a processing fixed support rod, a cooling mechanism, a cooling fan, and a cooling fan. The motion component and the laser processing component constitute a laser emitting mechanism. The processing fixed support rod is located at the bottom of the laser processing component. In use, the silver jewelry to be processed is placed on the processing fixed support rod. The cooling mechanism generates cold air, which is then blown into the guide tube by the cooling fan. The guide tube directs the cold air to the surface of the processing fixed support rod, cooling the silver jewelry on the rod. This continuous cooling during laser engraving prevents the silver jewelry from melting and collapsing due to excessive localized heat absorption, which would result in a blurry pattern and improve the precision of the silver jewelry processing.
