DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0027] like Figure 1 and Figure 2 A nameplate positioning device for a laser marking machine includes a base 1, a positioning platform 2 rotatably mounted on the top surface of the base 1, and a mask slidably arranged on the positioning platform 2.

[0028] like Figure 3 The positioning platform 2 is rotatably connected to the base 1 via a rotating shaft at the center of the top surface of the base 1. The positioning platform 2 is provided with a guide groove 2-4 for adjusting the installation angle. Preferably, the guide groove 2-4 is arc-shaped. A connecting component is fixed to the top surface of the base 1, passing through the guide groove 2-4 and connected to a nut. This design enables the positioning platform 2 to rotate around the rotating shaft on the top surface of the base 1 to a certain angle, ensuring its flexibility and adaptability in various application scenarios.

[0029] The positioning platform 2 is also provided with a positioning mechanism for positioning the nameplate, which includes a transverse positioning groove 2-1 and a longitudinal positioning groove 2-2 that are perpendicular to each other.

[0030] As a preferred embodiment of the present invention, multiple groups of positioning baffles 2-3 are provided in the transverse positioning groove 2-1 and the longitudinal positioning groove 2-2, respectively, corresponding one to one and intersecting perpendicularly. Each group of adjacent positioning baffles 2-3 are parallel to each other and arranged equidistantly. The intersection of the ends of each group of positioning baffles 2-3 is fixed to the top surface of the positioning platform 2 by positioning columns. Multiple groups of positioning baffles 2-3 form multiple transverse T-slots with the transverse positioning groove 2-1, and multiple groups of positioning baffles 2-3 form multiple longitudinal T-slots with the longitudinal positioning groove 2-2.

[0031] like Figure 4 and Figure 5The limiting structure 5 includes a shell 5-1 and a bottom plate 5-3. The bottom of the shell 5-1 is provided with a protrusion that cooperates with the T-shaped groove to limit the upward movement of the shell 5-1.

[0032] The housing 5-1 has through-holes on both the inner and outer sidewalls for the matte to pass through. The height of the through-hole on the outer wall is greater than that of the through-hole on the inner wall. A tightening structure 5-2 is provided within the housing 5-1. The two sides of the bottom surface of the tightening structure 5-2 are connected to the top surface of the base plate 5-3 via springs 5-4 on corresponding sides. Preferably, the top of the tightening structure 5-2 has inclined surfaces on both the inner and outer sides to facilitate the passage of the matte.

[0033] Specifically, a transversely disposed limiting structure 5 is slidably connected within the T-shaped groove of the transverse positioning groove 2-1, and a longitudinally disposed limiting structure 5 is slidably connected within the T-shaped groove of the longitudinal positioning groove 2-2. The limiting structure 5 within the transverse positioning groove 2-1 is shorter than the limiting structure 5 within the longitudinal positioning groove 2-2.

[0034] like Figure 3 The positioning mechanism further includes an elastic blocking piece 6 for locking the limiting structure 5 in the T-shaped groove. Preferably, the elastic blocking piece 6 is U-shaped.

[0035] The mask passes through and is slidably connected to the top of the limiting structure 5; a laser through-hole is provided on the mask. As a preferred example of the present invention, the mask includes an upper mask 3 and a lower mask 4. The width of the upper mask 3 is smaller than the width of the through-hole at the top of the limiting structure 5 in the transverse positioning groove 2-1, and its length is greater than the length of the positioning platform 2. The upper mask 3 can move forward and backward or left and right in the through-hole of the limiting structure 5 in the transverse positioning groove 2-1. The length of the lower mask 4 is equal to the length of the through-hole at the top of the limiting structure 5 in the longitudinal positioning groove 2-2. The lower mask can move forward and backward in the through-hole at the top of the limiting structure 5 in the longitudinal positioning groove 2-2. The length of the laser through-hole on the upper mask 3 is smaller than the length of the laser through-hole on the lower mask 4. The size of the laser through-hole can be adjusted by adjusting the positions of the upper mask 3 and the lower mask 4.

[0036] Preferably, the top surface of the positioning platform 2 is further provided with a plurality of grooves for facilitating the taking of nameplates.

[0037] The following example illustrates the method of using the nameplate positioning device of the utility model for a laser marking machine.

[0038] First, secure the base 1 of the device to the base of the laser marking machine. Then, connect the positioning platform 2 to the rotating shaft on the top surface of the base 1. Next, adjust the mounting angle of the positioning platform 2 and tighten it with a nut. Then, insert the limiting structure 5 in the transverse positioning slot 2-1 into the corresponding T-slot within the transverse positioning slot 2-1, and insert the limiting structure 5 in the longitudinal positioning slot 2-2 into the corresponding T-slot within the longitudinal positioning slot 2-2, depending on the size of the nameplate. Use elastic retaining plates 6 to lock the limiting structures 5 in the transverse positioning slot 2-1 and the limiting structures 5 in the longitudinal positioning slot 2-2 into their corresponding T-slots, preventing them from moving within the T-slots. Next, place the nameplate on the positioning platform 2 and insert the lower and upper shielding plates 4 and 3, respectively. Finally, adjust the positions of the upper and lower shielding plates 3 and 4 according to the marking area, so that the laser through-holes, when superimposed, fit within the marking area and block the open surface of the non-marking area to prevent contamination of the nameplate by smoke and dust generated during the marking process.

[0039] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
