Description

Technical Field

[0001] The present invention relates to the technical field of laser marking machines, in particular to an integrated laser marking machine. Background Art

[0002] Laser marking machines use laser beams to permanently mark the surfaces of various materials. Marking creates a delicate pattern, logo, or text by evaporating the surface material, revealing the underlying material. Laser marking machines are primarily categorized as CO2 lasers, semiconductor lasers, fiber lasers, and YAG lasers. Currently, laser marking machines are primarily used in applications requiring greater precision and accuracy. These applications include electronic components, integrated circuits (ICs), electrical appliances, mobile phones, hardware, tool accessories, precision instruments, eyewear and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.

[0003] A laser scanner, also known as a galvanometer, consists of an XY optical scanning head, an electronic drive amplifier, and optical reflective lenses. A signal from a computer controller drives the optical scanning head through the drive amplifier circuit, thereby controlling the deflection of the laser beam in the XY plane.

[0004] Existing laser marking machines adopt a split structure, with the galvanometer part, laser isolator and fiber laser at the output end separated into two parts. This results in more circuit connections connecting the two parts, the lines intersecting with each other, and the connecting wires crossing each other, making installation inconvenient. Moreover, all the lines are exposed to the external environment, making the lines more susceptible to damage. The staggered connecting lines are exposed to the outside, making the lines more susceptible to external forces. Once the lines are subjected to external forces, the equipment is more likely to be damaged and shut down. At the same time, the staggered lines exposed to the external environment are also prone to accidents, which increases the failure rate of the equipment.

[0005] Based on this, the present invention designs an integrated laser marking machine to solve the above problems. Summary of the Invention
