Description

Technical Field

[0001] The utility model relates to the technical field of silicone wristband processing, in particular to a laser engraving device for accessories used in silicone wristband processing. Background Art

[0002] The laser engraving process for silicone bracelets is to use a laser engraving machine to directly engrave patterns or texts on accessories such as bracelet straps and bracelet shells, thereby enhancing the uniqueness of the bracelet and making it more in line with people's tastes and needs; among them, the bracelet shell, as an important component of the smart bracelet, has a relatively large surface area and can provide more laser engraving space, which enables laser engraving on the bracelet to display richer and more complex designs to express personal uniqueness and personalized style.

[0003] However, during the laser engraving process, because the temperature of the laser is too high, when laser engraving non-metallic accessories such as plastic bracelet shells, when laser engraving the back of the bracelet shell, the laser will melt the shell material, and then produce residue. Some of the residue will stick to the shell, causing the case to be uneven and affecting the quality of the bracelet. Secondly, during the laser engraving process, the temperature of the laser engraving area and accessories is too high. When the staff removes the product, it is not easy to remove it immediately, affecting work efficiency. Utility Model Content
