[0046] 2. For the laser hole-opening equipment used in advertising sign production, the design of the cleaning mechanism can automatically wipe the lens of the laser head, prevent dust and smoke from contaminating the lens, ensure that the laser head always maintains good optical performance during cutting, improve the cutting quality and the stability of the equipment. The automatic cleaning function reduces the frequency of manual maintenance and lowers the operating cost.

[0047] 3. For the laser hole-opening equipment used in advertising sign production, the design of the cylinder and air rod of the moving mechanism provides stable power support, ensuring the smoothness of the laser head during movement. The structural design of the fixed block and slide rod further enhances the overall stability of the equipment, reduces the cutting error caused by vibration. The design of the hitting mechanism can vibrate and hit the billboard after cutting, making the cut part easier to fall off, improving the separation effect and reducing the workload of manual cleaning.

[0048] 4. For the laser hole-opening equipment used in advertising sign production, the pipeline is connected to a negative pressure fan, which can effectively suck the smoke and dust generated during cutting, reduce the pollution of the working environment, and meet the requirements of modern environmental protection. At the same time, the smoke is introduced into the coolant through the air pipe for degradation, further reducing the impact on the environment. The coolant system of the equipment can not only reduce the temperature of the workbench, prevent the billboard from deforming due to high temperature during cutting, but also further absorb the heat generated by cutting, optimize the working environment and improve the service life of the equipment.

[0075] The electric telescopic rod 38 is disposed at the bottom of the moving block 37 , and the output end of the electric telescopic rod 38 is connected to the laser head 8 for longitudinally moving the laser head 8 .

[0076] Preferably, the cleaning mechanism 4 further comprises:

[0077] The wiping block 43 is arranged in a mounting groove above the toggle plate 42, and the right sides of the toggle plate 42 and the wiping block 43 are arranged in an arc shape and contact the laser head 8, and is used to wipe the lens of the laser head 8;

[0078] A plurality of slide posts 44 are fixedly connected to the inner wall of the mounting groove, and the wiping block 43 is slidably connected to the outer wall of the slide post 44;

[0079] A spring 45 is sleeved on the outer wall of the slide post 44 and connected to the slide post 44 and the mounting groove, and is used to push the wiping block 43 to move upward;

[0080] One end of the pipe 46 is fixedly connected to the bottom of the shifting plate 42 , and the outer wall of the other end is connected to the outer wall of the moving block 37 .

[0081] Preferably, the pipe 46 is made of a hose, and the other end is connected to a vacuum cleaner for absorbing the smoke generated during cutting;

[0082] The telescopic end of the telescopic cylinder 1 41 is connected to the telescopic end of the electric telescopic rod 38 through a connecting plate, and the telescopic cylinder 1 41 moves along with the electric telescopic rod 38 .

[0083] Preferably, a rectangular groove is provided on the top of the workbench 1, and the inner wall of the rectangular groove is fixedly connected to the fixing frame 6, and the inner wall of the fixing frame 6 is provided with a placement component 7 for placing the billboard;

[0084] The placement component 7 comprises:

[0085] A plurality of vertical plates 71 are arranged at equal intervals and connected to the top of the fixed frame 6;

[0086] A plurality of second vertical plates 72 are connected between every two first vertical plates 71 at equal intervals;

[0087] The tops of the vertical plate 1 71 and the vertical plate 2 72 are wedge-shaped and in contact with the billboard;

[0088] The inner wall of the workbench 1 is provided with cooling liquid and is in contact with the fixing frame 6 , the vertical plate 1 71 and the vertical plate 2 72 .

[0089] Working principle: When laser cutting a billboard, the billboard is placed directly on the vertical board 1 71 and the vertical board 2 72, and then the cylinder is controlled to work according to the pre-set program. According to the position of laser cutting required, the two cylinders 34 in front and on the side are started at the same time, and the slider 35 is driven to move on the slide bar 32 by the cylinder 34 and the gas rod 33, so that the moving block 37 can be driven to move by the guide rod 36, and the moving block 37 can be fixed by moving with each other to achieve the purpose of stable cutting, and the electric telescopic rod 38 is started at the same time to adjust the position of the laser head 8 from the billboard to achieve the purpose of cutting the billboard;

[0090] When the cutting is completed, the electric telescopic rod 38 is reset, which drives the laser head 8 to move upward. When the laser head 8 moves downward, it contacts the top of the wiping block 43, and the laser head 8 contacts the wiping block 43 and presses the wiping block 43 and the toggle plate 42 downward. When the laser head 8 continues to move downward, the laser head 8 is out of contact with the wiping block 43, and the wiping block 43 is deflected to expose the bottom of the laser head 8, so as to cut the billboard and wipe the lens of the laser head 8 to prevent dust or smoke from contaminating the lens and reducing the accuracy and efficiency.

[0091] At the same time, the laser head 8 is reset upward, and the toggle plate 42 is reset upward to a horizontal state, so that the toggle plate 42 can always keep in contact with the outer wall of the laser head 8, thereby achieving repeated wiping of the bottom of the laser head 8.

[0092] See also Figures 1-8 Based on the above embodiment, in another embodiment of the present invention, preferably, the striking mechanism 5 includes:

[0093] The second telescopic cylinder 51 is connected to the other side of the outer wall of the moving block 37, and the output end is connected to the telescopic end of the electric telescopic rod 38 through a connecting plate;

[0094] A movable rod 52 is movably connected to the inner wall of the telescopic end of the second telescopic cylinder 51;

[0095] The second spring 53 is arranged on the inner wall of the telescopic end of the second telescopic cylinder 51, and both ends of the second spring 53 are respectively connected to the movable rod 52 and the telescopic end of the second telescopic cylinder 51, and is used to push the movable rod 52 to move downward;

[0096] The striking block 54 is fixedly connected to the bottom of the movable rod 52 and contacts the billboard, and is used to strike the billboard.

[0097] Preferably, the striking mechanism 5 further includes:

[0098] The elastic rod 55 is fixedly connected to the outer wall of the movable rod 52, and a sliding hole is formed at the telescopic end of the second telescopic cylinder 51, and the elastic rod 55 slides in the sliding hole;

[0099] The push rod 56 is fixedly connected to the outer wall of the laser head 8 on one side, and the other side of the push rod 56 is semicircularly arranged and contacts one end of the elastic rod 55.

[0100] Preferably, one end of the pipeline 46 is connected with a negative pressure fan, and the other end of the negative pressure fan is led into the workbench 1 through an air pipe and is placed in the coolant.

[0101] Working principle: When the laser head 8 moves up and down and cuts the billboard, when the laser head 8 moves up, the push rod 56 will squeeze the elastic rod 55, thereby generating extrusion on the elastic rod 55. At this time, the elastic rod 55 moves to the lower side of the push rod 56. At this time, the restriction on the elastic rod 55 is released, and the movable rod 52 will move downward under the push of the second spring 53. At this time, it will drive the striking block 54 to move downward, thereby striking the billboard, vibrating and shedding the part still attached to the billboard main body after cutting, improving the separation effect;

[0102] At the same time, the negative pressure fan sucks the smoke generated during cutting through the pipeline 46 and degrades it through the air pipe into the coolant in the workbench 1, thereby improving the stability during work.
