However, in related technologies, the methods for simulating carbonized samples are mostly printing and using traditional soldering irons. However, the carbonized samples made by printing and using traditional soldering irons lack realism and consistency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a method for making carbonized marks.

[0005] A second aspect of the present invention provides a control device for making carbonized marks.

[0006] A third aspect of the present invention provides a readable storage medium.

[0007] In view of this, a first aspect of the present invention provides a method for making carbonized marks for securities. The method for making carbonized marks includes: obtaining a sample of the security; determining a multi-layer marking diagram of the sample of the security according to the sample of the security; setting operating parameters of a laser generator according to the multi-layer marking diagram; and controlling the laser generator to mark the sample of the security according to the operating parameters of the laser generator, so as to form a carbonized mark on the sample of the security.

[0008] In this technical solution, the method for making carbonized marks is used for securities, so that carbonized marks can be formed on the securities. Obtain a sample of the security; according to the sample of the security, determine the multi-layer marking diagram of the sample of the security, so that different marking diagrams can be selected according to different samples of the security. By obtaining the multi-layer marking diagram, it is convenient to determine the shape, depth and visual effect of the carbonized mark. According to the multi-layer marking diagram, set the operating parameters of the laser generator. By adjusting the operating parameters of the laser generator, it can be ensured that the focusing and intensity of the laser beam generated by the laser generator reach the optimal state, so as to achieve precise control of the laser generator. According to the operating parameters of the laser generator, control the laser generator to mark the sample of the security, so as to form carbonized marks on the sample of the security, so that the laser generator can form carbonized marks on the sample of the security according to the marking diagram by adjusting the operating parameters, so that the sample of the security has a carbonized effect. By adopting the laser generator to adjust the operating parameters of the laser in this application, the degree and range of the pyrolysis reaction of the local part of the sample of the security can be controlled, so as to form carbonized sample sheets with different levels and effects, thereby improving the realism of the carbonized marks on the sample of the security.

[0010] In this technical solution, by using defocused laser, when the laser irradiates the sample of the security, due to the focus not being at the center position of the sample of the security, a defocus phenomenon will occur, increasing the spot width of the laser and at the same time reducing the energy density per unit area. Since the energy density of the laser is extremely high, the paper will be rapidly heated after absorbing the laser energy. When the temperature reaches a certain level, pyrolysis reaction will occur in the local area of the paper, producing a carbonized effect. Moreover, the method of using defocused laser can also avoid damage to the sample of the security caused by the high laser energy after the laser irradiates the sample of the security.

According to the first marking pattern, the first parameter of the laser generator is obtained. According to the second marking pattern, the second parameter of the laser generator is obtained; according to the third marking pattern, the third parameter of the laser generator is obtained, so that the laser generator can operate according to the first parameter, the second parameter, and the third parameter respectively, thereby ensuring that the carbonization marks of each layer can be accurately controlled and optimizing the carbonization effect of each layer.

Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0036] Next, refer to Figures 1 to 4 to describe a method for making carbonized marks and a control device for making carbonized marks according to some embodiments of the present invention.

[0037] The present invention provides a method for making carbonized marks for securities, such as Figure 1 as shown, Figure 1 Figure 1 shows a schematic flow chart of a method for making carbonized marks according to an embodiment of the present invention. The method for making carbonized marks includes: S102, obtaining a sample of the security; S104, determining a multi-layer marking diagram of the sample of the security according to the sample of the security; S106, setting the operating parameters of the laser generator according to the multi-layer marking diagram; S108, controlling the laser generator to mark the sample of the security according to the operating parameters of the laser generator, so as to form a carbonized mark on the sample of the security.

[0038] In this embodiment, the method for making carbonized marks is used for securities, so that carbonized marks can be formed on the securities. Obtain a sample of the security; according to the sample of the security, determine the multi-layer marking diagram of the sample of the security, so that different marking diagrams can be selected according to different samples of the security. By obtaining the multi-layer marking diagram, it is convenient to determine the shape, depth and visual effect of the carbonized mark. According to the multi-layer marking diagram, set the operating parameters of the laser generator. By adjusting the operating parameters of the laser generator, it can be ensured that the focusing and intensity of the laser beam generated by the laser generator reach the optimal state, so as to achieve precise control of the laser generator. According to the operating parameters of the laser generator, control the laser generator to mark the sample of the security, so as to form a carbonized mark on the sample of the security, so that the laser generator can form a carbonized mark on the sample of the security according to the marking diagram by adjusting the operating parameters, so that the sample of the security has a carbonized effect. By using the laser generator to adjust the operating parameters of the laser in this application, the degree and range of the pyrolysis reaction of the local part of the sample of the security can be controlled, so as to form carbonized samples with different levels and effects, thereby improving the realism of the carbonized marks on the sample of the security.

[0039] Specifically, when the laser irradiates the sample of the security, when the temperature of the sample of the security reaches a certain degree, the local area of the paper will undergo a pyrolysis reaction, so that a carbonized effect can be produced.

[0043] In an embodiment of the present invention, optionally, the laser generated by the laser generator is defocused laser.

[0044] In this embodiment, by using defocused laser, when the laser irradiates on the sample of the security, since the focus is not at the center position of the sample of the security, a defocus phenomenon will occur, increasing the spot width of the laser and at the same time reducing the energy density per unit area. Due to the extremely high energy density of the laser, the paper will be rapidly heated after absorbing the laser energy. When the temperature reaches a certain level, a pyrolysis reaction will occur in the local area of the paper, producing a carbonization effect. Moreover, the method of using defocused laser can also avoid damage to the sample of the security caused by the high laser energy after the laser irradiates on the sample of the security.

[0046] In this embodiment, a focusing lens is set between the emitting end of the laser generator and the sample of the security, so as to achieve the focusing and energy concentration of the laser beam emitted by the laser generator. The focusing lens can converge the diverging laser beam onto a small point. The focused laser energy can heat the local material to a certain temperature in a short time, so as to facilitate marking on the sample of the security.

[0047] In an embodiment of the present invention, optionally, according to the shape of the sample of the security, the defocus angle of the laser of the laser generator is set.

[0049] Specifically, according to the shape of the sample of the security, setting the defocus angle of the laser of the laser generator can be achieved by setting different laser focusing lenses and / or the angles and heights of the security.

[0050] In an embodiment of the present invention, optionally, obtaining the sample of the security includes: obtaining a piece of paper with a first preset thickness and material as the sample of the security.

The laser generator is controlled to perform a third-layer marking process on the second mark according to the third parameter and the third marking pattern to form a carbonized mark on the sample of the negotiable instrument, thereby realizing the production of the carbonized mark. By controlling the laser generator to perform three-layer marking processes according to different parameters and marking patterns, the production of the carbonized mark is realized, so as to form carbonized sample sheets with different layers and effects, and improve the authenticity and uniqueness of the carbonized sample sheets.
