[0037] The visible light mirror 16 is connected with the first mounting frame 17, the visible light mirror 16 is located on the shooting path of the precise positioning camera 15 and the marking path of the marking machine body 13, so that the precise positioning camera 15 can acquire the image of the marking area through the visible light mirror 16.

[0038] The second mounting bracket 18 is connected to the working platform 11, and the initial camera 14 is connected to the top of the second mounting bracket 18.

[0039] Please refer to Figure 2 In this embodiment, the first mounting bracket 17 includes a connecting seat 171, a vertical support plate 172, and a horizontal support plate 173. The connecting seat 171 is connected to the marking machine body 13, and the bottom end of the vertical support plate 172 is connected to the connecting seat 171. The vertical support plate 172 is provided with a first vertical elongated hole 1721 extending vertically. The horizontal support plate 173 is adjustablely connected to the first vertical elongated hole 1721 by screws.

This allows the position of the precision camera 15 to be flexibly adjusted to adapt to the marking needs of different products.

[0040] In this embodiment, a notch 1723 is provided at the bottom end of the vertical support plate 172. The two inner wall surfaces of the notch 1723 are respectively in positioning contact with the two adjacent side surfaces of the connecting seat 171 to achieve a stable positioning fit between the vertical support plate 172 and the connecting seat 171.

[0043] The dual-camera high-efficiency positioning laser marking equipment of this embodiment also includes a light source 19. The light source 19 is connected to the connecting base 171 through the mounting plate 174. The light source 19 is located below the anti-laser visible light mirror 16 and shines light towards the working platform 11 to ensure uniform illumination of the marking and photographing areas and improve positioning accuracy.

[0044] Please refer to Figure 2 and Figure 3In this embodiment, the light source 19 is a long strip light, and at least two light sources 19 are connected to the mounting plate 174. The shooting path of the precision camera 15 and the marking path of the marking machine body 13 are located between the two light sources 19. Each of the two light sources 19 includes a first light-emitting surface 191, and the first light-emitting surfaces 191 of the two light sources 19 are directed toward the area on the working platform 11 corresponding to the area between the two light sources 19. That is, the marking and shooting areas can be illuminated from at least two directions, resulting in uniform illumination and good lighting effect.

[0045] Please refer to Figure 3 The mounting plate 174 is provided with a connection hole 1742 and an arc groove 1743 with the connection hole 1742 as the center. The axial end face of the lamp 19 is connected to the connection hole 1742 and the arc groove 1743 by screws, so that the lamp 19 and the mounting plate 174 form a rotatable connection, which facilitates the adjustment of the illumination angle.

[0046] In addition, the mounting plate 174 is provided with a second vertical elongated hole 1741 extending vertically. The connecting seat 171 is tunably connected to the second vertical elongated hole 1741 by screws, so that the distance between the light supply lamp 19 and the working platform 11 can be adjusted.

[0047] The dual-camera high-efficiency positioning laser marking equipment in this embodiment also includes a lifting drive mechanism 123, a longitudinal drive mechanism 121, and a transverse drive mechanism 122. The longitudinal drive mechanism 121 is mounted on the work platform 11, and the movable crossbeam 12 is connected to the output end of the longitudinal drive mechanism 121. The transverse drive mechanism 122 is mounted on the movable crossbeam 12, and the lifting drive mechanism 123 is connected to the output end of the transverse drive mechanism 122.

The initial position is located in the middle of a side above the work platform 11, parallel to the extension direction of the light source 19. A light source 19 located away from the initial position also includes a second light-emitting surface 192, which emits light towards the center area of ​​the work platform. Thus, when the marking machine body 13 moves to the initial position, it can control the light source 19 to emit light through the second light-emitting surface 192 onto the product on the work platform 11, improving the shooting accuracy of the initial camera 14.

[0049] It is understandable that lamp components can be set in the lamp 19 corresponding to the first light-emitting surface 191 and the second light-emitting surface 192 respectively, and then the opening and closing of different lamp components can be controlled by the controller to achieve light supply to different light-emitting surfaces.

[0050] The working principle of the dual-camera high-efficiency positioning laser marking equipment in this embodiment is as follows: After the product is placed on the work platform 11, the marking machine body 13 first moves to the initial position. At this time, the initial positioning camera 14 can take a wide-range picture of the product on the work platform 11. The light source 19 provides uniform illumination through the second light-emitting surface 192 to ensure the shooting accuracy of the initial positioning camera 14. The initial positioning camera 14 transmits the picture information to the controller. The controller analyzes and identifies the marking points to obtain the preliminary position information of the product.

[0051] Based on the initial positioning information, the controller moves the marking machine body 13 and the precision camera 15 to the vicinity of the target area. The precision camera 15 takes high-precision pictures of the marking area through the anti-laser visible light mirror 16, and the light source 19 provides uniform illumination through the first light-emitting surface 191 to ensure the shooting accuracy of the precision camera 15. The precision camera 15 transmits the picture information to the controller, which analyzes and identifies the marking points to obtain the precise position information of the product.

[0052] Finally, based on the precise positioning information, the controller controls the marking machine body 13 to perform precise marking.

[0053] This completes the marking process of the dual-camera high-efficiency positioning laser marking equipment in this embodiment.

[0054] The dual-camera high-efficiency positioning laser marking equipment of this preferred embodiment achieves large-area initial positioning and small-area high-precision positioning through the cooperation of the initial positioning camera and the fine positioning camera, which can improve marking efficiency and accuracy.

[0055] The design of the first and second light-emitting surfaces of the light source allows the light source to be used simultaneously for both preliminary and final shooting, improving shooting accuracy while maintaining low overall cost.

[0056] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
