In an embodiment of the present invention, as shown in fig. 3 to 8, there is provided an anti-blur laser cutting method, including the steps of:

s100: selecting materials, namely selecting a gasket raw material 10 required by manufacturing the gasket; in order to obtain materials, some materials commonly used by printing enterprises, such as thin paper and plastic (PP/PVC/PC) sheets, can be selected as the gasket raw material 10;

s200: drawing processing, namely manufacturing a product cutter line 100 in a CAD file, a gasket crack 200 which is biased inwards and outwards along the product cutter line 100 and a plurality of round holes 300 which are positioned on the peripheral side of the gasket crack 200, and storing the product cutter line as a DXF file;

s300: manufacturing a gasket, namely guiding the DXF file into a cutting device, placing the gasket raw material 10 on a platform of the cutting device, burning and cutting the gasket raw material 10 along the gasket crack 200 and the round hole 300, and removing waste materials blocked in the gasket crack 200 and the round hole 300 to form the gasket;

s400: and product cutting, namely placing a product raw material 20 to be cut on the gasket, ensuring that the product raw material 20 covers the corresponding product knife line 100 and the round hole 300 on the gasket, and burning and cutting the product raw material 20 along the product knife line 100 to form a product. Referring to fig. 8, the laser beam 30 emitted by the cutting device passes through the gasket nip 200 of the gasket material 10 to burn the product material.

According to the laser cutting method for preventing the burnt edges, provided by the embodiment of the invention, after the gasket raw material 10 is selected, the gasket is made into a specific gasket according to the cutting shape of a product to be burnt and cut specifically, the gasket is placed on the cutting equipment, then the product raw material 20 is covered on the gasket, and when the product raw material 20 is burnt and cut, the light path of the cutting equipment advances along the pre-made product clamping seam until the burning and cutting are completed. In the process of burning and cutting, the invention can prevent the generated smoke dust with high temperature and high heat from being adsorbed on the product, the discharged product can not generate burnt edges, the product does not need to be cleaned, the time is saved, and the efficiency is improved. Solves the problems of low efficiency, unclean treatment and imperfect treatment of products which are obtained by burning out certain materials (such as Taivik paper and other materials containing rich fibers) by laser during the dirty treatment.

In one embodiment, in the step S100, 350 to 400g of art paper or book card paper with a thickness of 0.35 to 0.45mm is selected as the gasket raw material 10. Specifically, the gasket stock material 10 is selected to have the advantages of being readily available and inexpensive. The parameter selection of the material can ensure that the distance between the material to be cut and the platform supporting grid is smaller due to the thinness, so that the isolation effect cannot be realized, and the problem of dirt cannot be solved; and not too thick to cause accuracy in focusing the laser beam 30. The thickness of the gasket raw material 10 is controlled to be 0.35-0.45 mm through infinite times of experiments, so that the effect is the best, the formed gasket has an isolation effect, and meanwhile, the effectiveness and the stability of laser focusing can be guaranteed.

The thickness of the gasket material 10 may be 0.35m, 0.40mm or 0.45mm, which is 350-400 g of coated paper or paperboard.

In one embodiment, in step S200, the product blade line 100 is biased by OFFSET command in CAD software, biased inward and biased outward by 0.4-0.5 mm, and then the extra lines are cut by TRIM command so that the width of the shim slit 200 is between 0.8-1.0 mm. Particularly, the step is conveniently executed in CAD software, and the method is high in correction and precision. When the offset value is small, the effect cannot be achieved, the gasket can be cut by an actual light path due to slight movement of the material to be cut and the gasket when a product is cut, the effect is reduced, and if the offset value is large, the material to be cut can bend at the cut and even can contact with the supporting grid of the platform due to downward pulling force caused by air suction, so that the effect is reduced.

In one embodiment, in the step S200, the circular holes 300 are distributed inside and outside the outer periphery of the gasket slot 200. Further, the outer diameter of the circular hole 300 is 10 mm. Specifically, since the spacer is made of a non-air-permeable material, in order to maintain the adsorption of the raw material 20 of the product to be cut, the circular hole 300 is formed with an air guide hole on the raw material 10 of the spacer after being cut, and the air guide hole is set to have a diameter of 10mm, so that the platform of the cutting device can suck air and can also penetrate through the spacer to suck the raw material 20 of the product to be cut, thereby fixing the raw material 20 of the product to be cut.

In one embodiment, in the step S200, the product knife line 100 is set to be displayed in a first color in a CAD file, and the shim slit 200 is set to be displayed in a second color. Specifically, black is set as the manufactured gasket crack 200, and red is set as the product knife line 100, so that software identification in the cutting equipment can be facilitated, and a DXF file is stored after the drawing is processed, so that the software can be conveniently imported and processed.

Further, in the step S300, importing the DXF file into a cutting device specifically includes: loading the information of the product knife line 100, the information of the gasket gap 200 and the information of the round hole 300 into a system of the cutting equipment, automatically appointing layers for the product knife line 100 and the gasket gap 200 which are displayed in different colors, firstly turning off the output of the product knife line 100, only outputting the gasket gap 200, and adjusting the cutting parameters of the system.

In an embodiment, in the step S400, if the raw product material 20 cannot cover all the circular holes 300, paper or a film material is used to block the holes of the platform that are not covered by the raw product material 20. Specifically, the suction device of the cutting apparatus generates a stronger suction force to the raw product material 20 to be cut so as not to cause a problem of displacement. After the shape of the gasket is cut, the scraps blocked on the crack of the circular hole 300 are taken away by a forceps; further, after the waste materials are picked up in the previous step, the air suction state of the air suction device is kept unchanged, the adsorption force of the platform of the cutting equipment on the gasket is kept, the raw material 20 of the product to be cut is placed on the gasket, and the raw material 20 of the product to be cut can be ensured to cover a product lead (along the central line of the gasket gap 200) so as to ensure the integrity of the final product which is cut by burning, as can be seen from a comparison chart of fig. 9, the left side is the product which is manufactured by the prior art and has a burned edge, and the right side is the product which is manufactured by the method of the embodiment of the invention and has no burned edge.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
