Description

technical field [0001] The invention relates to a laser equipment protection device. Background technique [0002] Laser cladding is an emerging surface modification technology. By adding cladding materials on the surface of the substrate and melting with high-energy laser beams, a cladding layer with a composite functional structure, low dilution rate, and small welding deformation is formed. The cladding process of heating and cooling makes it easy to obtain a high-quality and wear-resistant cladding layer. Laser cutting technology uses a high-power-density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. As the beam moves to the material, the holes are continuously formed with a narrow width (such as about 0.1mm) Slitting, the technique of cutting material. Both laser cladding and laser cutting technologies have the characteristics of small thermal deformation of the wor...

AI Technical Summary

Problems solved by technology

Both laser cladding and laser cutting technology have the characteristics of small thermal deformation of the workpiece and high work efficiency, but there are also many shortcomings in the processing process, such as laser reflection, dust splashing, etc.

[0003] The metal dust splashed during laser cladding or laser cutting is easy to adhere to the protective lens of the laser head, which accumulates over time and needs to be replaced. If the replacement is not timely, it may even cause serious consequences such as burnout of the laser head. It not only affects work efficiency and quality, but also increases cost input

In the current production work, most of the solutions to this problem are to install a copper plate at a certain distance from the lower end of the laser head, and install a simple gas nozzle on the side of the laser head to remove the splashed dust, but these methods are generally effective in removing dust. , the installation of the copper plate is also largely affected by the clamping position of the processed workpiece, and sometimes it cannot even be installed
