[0041] like Figures 1 to 5 As shown, the embodiment of the present invention provides a laser marking tool suitable for a large decorative cover, comprising: a rotating plate 1, which is horizontally arranged, and a large decorative cover 3 to be marked is detachably arranged on the rotating plate 1, wherein the large decorative cover 3 is divided into multiple areas according to the content to be marked; a lifting plate 2, which is horizontally arranged and located below the rotating plate 1, and the rotating plate 1 is arranged at the center of the lifting plate 2 in a manner that it can rotate around its vertical central axis, and a plurality of positioning holes 16 corresponding to the divided areas are provided on the lifting plate 2, and the plurality of positioning holes 16 are located on the same circle, and the center of the circle is located at the On the vertical center axis of the rotating plate; a driving cylinder assembly, which is arranged below the lifting plate 2, the piston rod of the driving cylinder assembly is vertically arranged, and the end of the piston rod is fixedly connected to the bottom surface of the lifting plate 2; an directional column 13, which is vertically arranged, one end of the directional column 13 is inserted into one of the positioning holes 16, and the other end is movably connected to the rotating plate 1 in a manner that can be moved up and down in the vertical direction; wherein, when one area is printed, the directional column 13 is moved upward, the rotating plate 1 is rotated and the directional column 13 is inserted into another adjacent positioning hole 16, so that the laser marking machine marks another area.

[0042] In the above embodiment, the shape of the rotating plate 1 is not specifically limited, and it can be round or square. The large decorative cover 3 is detachably arranged on the top of the rotating plate 1. The specific setting method, that is, the clamping method, is not specifically limited in this embodiment. The clamping method can be set according to the shape of the large decorative cover 3. The existing technology can be used and will not be described here. For example, an annular groove is provided at the center of the rotating plate 1, and the large decorative cover 3 is clamped in the annular groove. Since the laser marking machine is fixedly arranged above the rotating plate, if the font or pattern marked by the laser marking machine is to be clear, the plane height difference of the font or pattern is required to be within 4mm, and the typing range is within the 80X80mm area. For a large decorative cover with a relatively large area and a middle area higher than the edge area, it is impossible to complete the marking of the entire upper surface of the large decorative cover at one time. Therefore, the rotating plate 1 provided in the utility model is arranged at the center of the lifting plate 2 in a manner that can rotate around its vertical center axis, and the large decorative cover 3 is divided into multiple areas according to the content to be marked. The multiple areas can be the same or different, such as Figure 3 As shown, the divided areas are not the same, and the large decorative cover 3 is divided into 5 areas. By rotating the rotating plate, the large decorative cover is driven to rotate, and then the area to be marked is rotated to the bottom of the laser marking machine. When one area is marked, the rotating plate 1 is rotated to move the rotating plate 1 to the next area to be marked, so that the laser marking machine can continue to mark another area until all areas are marked; the set driving cylinder assembly can drive the lifting plate 2 to move up and down in the vertical direction, so as to adjust the height of the entire large decorative cover 3, so as to be able to mark positions with different heights on the upper surface of the large decorative cover. Therefore, the rotating plate 1, the lifting plate 2 and the driving cylinder assembly realize the rotation and lifting of the large decorative cover 3, and the large decorative cover 3 only needs to be clamped once to complete the marking of the entire large decorative cover 3. Since the present embodiment is provided with a plurality of positioning holes 16 corresponding to the divided areas on the lifting plate 2, the plurality of positioning holes 16 are located on the same circle, such as Figure 3As shown, five positioning holes 16 are provided, corresponding to work stations 1 to 5 respectively, and one end of the provided directional column 13 is inserted into one of the positioning holes 16, and the other end is movably connected to the rotating plate 1 in a manner that can move up and down in the vertical direction. When printing of one area is completed, the directional column 13 is moved upward so that the directional column 13 leaves the positioning hole 16, and the rotating plate 1 is rotated so that the directional column 13 moves to the next adjacent positioning hole 16, and then the directional column 13 is inserted into the next adjacent positioning hole 16, thereby fixing the rotating plate 1 and the large decorative cover 3, so that the laser marking machine can continue to mark another area. Therefore, the provided directional column 13 can enable the laser marking machine to orient the rotating plate 1 and the large decorative cover 3 when marking the large decorative cover 3, so that the rotating plate 1 and the large decorative cover 3 will not rotate, thereby ensuring the accuracy and precision of the marking. It should be noted that the positioning hole 16 can be a through hole or a groove. If the positioning hole 16 is set as a through hole, in order to prevent the lower end of the directional column 13 from passing through the through hole, it is necessary to provide a clamping portion at the lower end of the directional column 13. The cross-section of the clamping portion is larger than the cross-section of the positioning hole 16, so that the lower section of the clamping portion of the directional column 13 is inserted into the positioning hole 16. If the positioning hole 16 is set as a groove, the lower end of the directional column 13 does not need to be provided with a clamping portion.

[0043] In one specific embodiment, the laser marking tooling for a large decorative cover further includes:

[0044] The directional seat 11 has an L-shaped cross-section. The free end of the horizontal portion of the directional seat 11 is fixedly connected to the side of the rotating plate 1.

The rotating plate 1 is rotated so that the first through-hole and one of the positioning holes 16 are located on the same vertical line. The lower end of the directional column 13 is inserted into the corresponding positioning hole 16.

[0045] One end of the rocker 10 is rotatably connected to the upper end of the directional column 13. The vertical portion of the directional seat 11 is rotatably connected to the rocker 10. When the other end of the rocker 10 is pressed downward, the end of the directional column 13 leaves the positioning hole 16.

[0046] The spring 12 is movably mounted on the directional column 13 , wherein a clamping portion is provided on the circumference of the lower end of the directional column 13 near the end portion, and the spring 12 is located between the rotating plate 1 and the clamping portion of the directional column 13 .

[0047] In the above embodiment, the directional seat 11, rocker 10 and spring 12 are provided to press the free end of the rocker 10 downward. At this time, the spring 12 is compressed, which can make the directional column 13 leave the positioning hole 16, so that the rotating plate 1 can be rotated. When the rotating plate 1 rotates to make the rocker 10 rotate to the adjacent positioning hole 16, the free end of the rocker 10 is released, and the compressed spring 12 can make the lower end of the directional column 13 insert into the adjacent positioning hole 16. Therefore, the directional seat 11, rocker 10 and spring 12 are provided to facilitate the directional column 13 to leave or insert into the positioning hole 16, saving time and effort and improving efficiency. In specific implementation, the rotating plate 1 can be set to be circular, but the fixed connection with the horizontal part of the directional seat 11 is linear, and the multiple positioning holes 16 are all located on the outside of the rotating plate 1. That is to say, when viewed from above, the rotating plate 1 will not cover the positioning holes 16. Figure 3 shown.
