Description

Technical Field

[0001] This utility model belongs to the field of laser engraving equipment technology, and in particular relates to an ultraviolet laser engraving machine. Background Technology

[0002] Ultraviolet laser engraving is a technology that uses high-energy ultraviolet photons to break the molecular bonds on the surface of materials, causing molecules to detach from the object, thereby achieving fine marking or engraving. Ultraviolet laser engraving machines are widely used in many industries, such as consumer electronics, medical devices, automobile manufacturing, solar panels, lithium batteries, and jewelry. With its high precision, high efficiency, and low heat impact, ultraviolet laser engraving machines have become an important tool in modern manufacturing and precision machining.

[0003] The laser engraving process of an ultraviolet laser engraving machine mainly includes: laser generation, beam focusing, material processing, and movement control. It utilizes a cold processing method using high-energy ultraviolet photons to achieve precise marking and engraving on various materials.

[0004] In existing technologies, the product needs to be positioned or fixed in advance before the laser is generated and the beam is focused. In most cases, the product is placed directly within the focusing range of the laser beam to facilitate laser engraving. However, this can cause the product to shift and affect the laser engraving effect. Alternatively, a tray that matches the material and product specifications can be used to place the product to avoid shifting its position. However, when laser engraving different specifications of products, other compatible trays need to be replaced. The entire operation process is cumbersome and affects the laser engraving effect.
