The specific meaning of the above terms in the embodiments of the present invention will be understood by those of ordinary skill in the art according to specific circumstances.
In one embodiment of the present invention, as shown in fig. 3 to 8, there is provided a laser cutting method for preventing edge sticking, comprising the steps of:
s100: selecting a gasket raw material 10 required for manufacturing a gasket; for easy material availability, materials commonly used by printing enterprises, such as thinner 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, forming a gasket crack 200 which is biased inwards and outwards along the product cutter line 100, and forming a plurality of round holes 300 positioned on the periphery of the gasket crack 200, and storing the gasket crack as a DXF file;
s300: manufacturing a gasket, namely guiding the DXF file into cutting equipment, placing the gasket raw material 10 on a platform of the cutting equipment, burning 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 a gasket;
s400: and (3) product cutting, namely placing the product raw material 20 to be cut on the gasket, ensuring that the product raw material 20 covers the corresponding product cutter line 100 and the round hole 300 on the gasket, and burning the product raw material 20 along the product cutter line 100 to form a product. Referring to fig. 8, the product raw material is burned after the laser beam 30 emitted from the cutting apparatus passes through the gasket slit 200 of the gasket raw material 10.
In the method for cutting the anti-sticking edge by using the laser provided by the embodiment of the invention, after the gasket raw material 10 is selected, a specific gasket is manufactured according to the cutting shape of a product to be burned and cut, the gasket is placed on cutting equipment, then the product raw material 20 is covered on the gasket, and when the product raw material 20 is burned and cut, the optical path of the cutting equipment advances along the prefabricated product clamping joint until the burning and cutting are completed. In the burning and cutting process, the invention can avoid the generated high-temperature and high-heat smoke dust from being adsorbed on the product, the product after the product is discharged can not produce paste 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 existing in the process of treating dirt of products which are cut out by laser sintering of certain materials (materials containing abundant fibers such as tavid paper and the like).
In one embodiment, in the step S100, a coated paper or a book cardboard having a thickness of 0.35-0.45 mm of 350-400 g is selected as the gasket raw material 10. In particular, the gasket raw material 10 is selected to have the advantages of easy access and low cost. The parameter selection of the material can ensure that the distance between the material to be cut and the platform supporting grid is smaller because the material is too thin, and the isolation effect is not achieved, so that the problem of dirt cannot be solved; and not so thick as to cause accuracy in focusing the laser beam 30. The thickness of the spacer raw material 10 was found to be controlled to be 0.35 to 0.45mm with the best effect through an infinite number of experiments, since the spacer formed has an isolating effect, and at the same time, the effectiveness and stability of focusing of laser can be ensured.
Wherein the thickness of the gasket raw material 10 may be 0.35m, 0.40mm or 0.45mm of coated paper or book block paper of 350-400 g.
In one embodiment, in step S200, the product cutter wire 100 is biased with an OFFSET command in CAD software, biased inward and biased outward by 0.4-0.5 mm, and then the excess wire is cut with a TRIM command such that the width of the shim gap 200 is between 0.8-1.0 mm. In particular, the step is convenient to execute in CAD software, high in university and precision. When the offset is small, if the offset value is small, the effect is not achieved, and when a product is cut, an actual light path can be cut to the gasket due to slight movement of the material to be cut and the gasket, so that the effect is reduced, and if the offset value is large, the material to be cut can be bent at the cut position and even can be contacted with the supporting grid of the platform due to downward pulling force of induced draft.
In an embodiment, in the step S200, the circular holes 300 are distributed inside and outside the outer circumference of the gasket slit 200. Further, the circular hole 300 has an outer diameter of 10mm. Specifically, since the spacer is made of a non-air-permeable material, in order to maintain the adsorption of the product raw material 20 to be cut, the circular holes 300 are arranged to form air guide holes on the spacer raw material 10 after being burnt and cut, and the air guide holes are set to be 10mm in diameter, so that the platform air suction of the cutting device can also penetrate through the spacer to suck the product raw material 20 to be cut, and the product raw material 20 to be cut is fixed.
In one embodiment, in the step S200, the product tool line 100 is set to a first color display and the shim gap 200 is set to a second color display in a CAD file. Specifically, black is set as the manufactured gasket crack 200, red is set as the product knife line 100, so that the design can facilitate the identification of software in the cutting equipment, and DXF files are stored after the drawing is processed, so that the software is imported and processed.
Further, in the step S300, importing the DXF file into a cutting device is specifically: loading the product knife line 100 information, the gasket slit 200 information and the round hole 300 information into a system of the cutting equipment, wherein the system automatically designates layers for the product knife line 100 and the gasket slit 200 which are displayed in different colors, firstly, turning off the output of the product knife line 100, only outputting the gasket slit 200, and adjusting the cutting parameters of the system.
In an embodiment, in the step S400, if the product raw material 20 cannot cover all the round holes 300, a paper or film material is used to seal the holes of the platform not covered by the product raw material 20. Specifically, the suction means of the cutting apparatus generates a stronger suction force to the product raw material 20 to be cut, so that the problem of displacement does not occur. After the shape of the gasket is cut out, taking away the waste materials blocked on the crack of the round hole 300 by using a pick-up; further, after the waste is picked up in the previous step, the suction state of the suction device is kept unchanged, the adsorption force of the platform of the cutting device to the gasket is kept, the product raw material 20 to be cut is placed on the gasket, the product raw material 20 to be cut is ensured to cover the product wire (along the center line of the gasket crack 200) so as to ensure the integrity of the final product which is burnt out, as can be seen by referring to the comparison chart of fig. 9, the left side is the product manufactured by the prior art with the burnt edge, and the right side is the product without the burnt edge manufactured by the method of the embodiment of the invention.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
