Description

Technical Field

[0001] This invention relates to the field of laser engraving through-hole devices for laptop shells, and particularly to a high-precision laser engraving through-hole device for laptop shells. Background Technology

[0002] A laser engraving machine uses a laser beam to carve permanent marks on the surface of a material or inside a transparent material. The laser beam can produce two kinds of effects on the material: chemical and physical effects. When the material absorbs the laser light instantly, it produces a physical or chemical reaction, thereby engraving marks or displaying patterns or text. Therefore, it is also called a laser marking machine or laser engraving machine.

[0003] Currently, Chinese utility model patent CN215393217U discloses a device for laser engraving through holes in a notebook shell, including a main body. The top of the main body is provided with an installation compartment. A laser engraving machine is provided at the middle position of one end of the top of the main body. Two bidirectional threaded rods are provided on both sides of the two ends inside the installation compartment. One end of one set of bidirectional threaded rods extends to the outside of the installation compartment. Both sides of the outer sides of the two sets of bidirectional threaded rods are fitted with internal threaded blocks.
