DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] See also Figure 1 and Figure 2 , respectively, are a schematic diagram of the three-dimensional appearance of the present invention and a schematic diagram of a partial three-dimensional appearance from another perspective. The present invention provides a laser marking device comprising a platform 1, a laser module 2 disposed above the platform 1, and a light shielding mechanism 3 disposed on the laser module 2 and movable toward the platform 1; wherein: The platform 1 is provided with a conveying mechanism 10 for feeding one or more marking materials 4. The conveying mechanism 10 has a holding area P at one end and a processing area W at the other end. A stopper 11 is provided between the holding area P and the processing area W. In the embodiment of the present invention, the stopper 11 may be formed by two L-shaped plates spaced apart and arranged oppositely to block the side edges of each marking material 4 and confine it to the holding area P. The marking materials 4 may be stacked in the holding area P and transported one by one toward the processing area W by the conveying mechanism 10. The laser module 2 is positioned relatively above the processing area W to perform laser marking on the marking materials 4 fed into the processing area W.

[0028] As mentioned above, the laser module 2 is used to perform laser marking operations on the marking material 4 and can be programmably controlled by a control system 20; the control system 20 can be a computer to control the text, pattern or graphics printed by the laser module 2.

[0029] Please also refer to Figures 1 to 3 As shown, the platform 1 is further provided with a material dividing mechanism 12 on the material waiting area P, and an adjustment assembly 13 provided at one end of the material waiting area P away from the processing area W. The material dividing mechanism 12 comprises two material dividing arms 120 located on both sides of the material waiting area P. The two material dividing arms 120 are configured to roughly correspond to the width of each marking material 4, and a wedge plate 121 is provided below each of the material dividing arms 120. The two wedge plates 121 can be displaced relative to each other to lift up all the marking materials 4 stacked on the material waiting area P, leaving only the bottom one (i.e., as shown in FIG. 1 ). Figure 4 As shown), the conveying mechanism 10 only sends the lowest marking material 4 through the lower limit baffle 11 into the processing area W (i.e., Figure 5 The adjustment assembly 13 includes an adjustment rod 130 and a stopper 131 that can be displaced on the adjustment rod 130. The stopper 131 can be adjusted to the length of each marking material 4 by cooperating with the aforementioned stopper plate 11. This allows marking materials 4 of varying lengths to be placed in the holding area P.

[0030] Furthermore, if Figure 6 As shown, the conveying mechanism 10 may include a driving motor 100 and two conveying rails 101 driven by the driving motor 100. The two conveying rails 101 may be composed of pulleys, and the two conveying rails 101 are spaced apart from each other and screwed together by an adjusting screw 102. The distance between the two conveying rails 101 can be adjusted by the adjusting screw 102, thereby being suitable for marking materials 4 with different widths. In addition, please refer to Figure 1 and Figure 2 As shown, the conveying mechanism 10 is provided with a discharge limiting module 103 at one end of the processing area W away from the waiting area P. When the marking material 4 is engraved by the laser module 2 in the processing area W, the discharge limiting module 103 can be raised to prevent the marking material 4 from falling, and after the engraving operation is completed, the discharge limiting module 103 is lowered to allow the marking material 4 to exit the processing area W along the conveying mechanism 10, and a loading container (not shown) or other equipment can be connected to the outside of the discharge limiting module 103 to accommodate the completed marking material 4 in the loading container.

[0031] like Figure 1 、 Figure 7 and Figure 8As shown, the shading mechanism 3 is provided outside the laser module 2 and includes a shading cover 30, a support cover 31 provided outside the laser module 2, and at least one swing arm 32 connected between the shading cover 30 and the support cover 31. The shading cover 30 is swung from the support cover 31 toward the bottom of the laser module 2 by the swing arm 32 (i.e., Figure 8 As shown), the light shield 30 is disposed in the processing area W so that when the laser module 2 performs laser marking operation, the light shield 30 can be used to block the laser light for protection.

[0032] In addition, if Figure 7 and Figure 8 As shown, the present invention is provided with a handle 33 on the outside of the above-mentioned sunshade 30, and a positioning element 330 is provided inside the sunshade 30 relative to the handle 33. The positioning element 330 can be a magnet, a suction cup or a snap-on part. The above-mentioned support cover 31 further has a surface 310 corresponding to the sunshade 30 on the outside. The surface 310 has a first fixed position P1 and a second fixed position P2. The surface 310 can be made of a material that can be adsorbed by a magnetic element, such as iron, or only the first fixed position P1 and the second fixed position P2 can be made of the above-mentioned material to facilitate the positioning element 330 to be adsorbed by a magnet; or a surface made of glass or acrylic can be used to facilitate the positioning element 330 to be adsorbed by a suction cup; or a structure such as a card slot or a buckle hole can be provided to facilitate the positioning element 330 to be buckled with each other. When the sunshade 30 swings upward with the swing arm 32, the positioning element 330 can be fixed at the first fixed position P1 (i.e., Figure 7 When the light shield 30 swings downward with the swing arm 32, the positioning element 330 is fixed at the second fixed position P2 (ie, Figure 8 (as shown) and placed over the processing area W of the platform 1. The light shield 30 can be easily lifted up by the fixing element 330 when positioned at the first fixing position P1 and stably placed over the processing area W when positioned at the second fixing position P2. Furthermore, a touch switch 311 can be provided at the second fixing position P2. When the touch switch 311 is pressed by the fixing element 330, the control system 20 activates the laser module 2 for marking, further providing safety during operation.

[0033] Therefore, the laser marking device of the present invention can be obtained by the above-mentioned structural composition.

[0034] The above embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
