[0019] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 3As shown in the figure, this embodiment provides a visual laser engraving machine, including a frame 1, an adjustment component 2, a laser laser engraving device 3 and a visual detection device 4, the adjustment component 2 is arranged on the frame 1, the laser laser engraving device 3 is arranged on the adjustment component 2, and the adjustment component 2 is used to adjust the position of the laser laser engraving device 3;

[0022] The visual detection device 4 is arranged on the laser engraving device 3, and a one-way perspective lens 5 is provided on the optical axis of the visual detection device 4. The one-way perspective lens 5 is also arranged on the laser axis of the laser engraving device 3. The one-way perspective lens 5 is used to reflect the laser beam of the laser engraving device 3 to coincide with the optical axis of the visual detection device 4.
