Technical Field

Background

In daily life, we can see a large number of products which are packaged by external packaging, for example, products packaged by thermoplastic films, typically various bottle caps are often packaged by a thermoplastic film for sealing after being mounted, one is low in cost, and the other is good in sealing effect. However, due to the low cost and simple process, ordinary people can easily perform malicious secondary packaging after unsealing the package, and thus the problems of counterfeiting, package dropping, malicious claims and the like can easily occur.

In the prior art, for example, serial numbers, production batch numbers, quality guarantee periods and other modes are printed at a packaging position in a code spraying or laser marking mode, and the modes are easy to imitate, are only used for tracing production information of products and cannot play a role in anti-disassembly and anti-counterfeiting.

Alternatively, a laser may be used to mark a non-disruptive pattern on the edges of the thermoplastic film and the corresponding surface of the product, the pattern having a portion on each of the film and the surface of the product, the pattern being tamper-evident by identifying the integrity and location of the pattern at the interface after the film is peeled away. In the method, because the patterns are fixed, the butt joint of the patterns can also realize accurate position positioning through industrial CCD positioning, so that the occurrence of counterfeiting cannot be avoided technically.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the present invention provides a preferred embodiment of an anti-counterfeiting tamper-evident method.

An anti-counterfeiting tamper-evident method, comprising the steps of:

step S11, an engraving pattern consisting of points or/and discontinuous lines is set;

step S12, setting laser parameters for processing the carving pattern;

step S13, using laser to puncture the outer package and forming an engraved pattern on the corresponding position of the product or its inner package surface.

Specifically, the product itself or the outside is formed into an inner package, and an outer package is sealed on the product or the inner package, preferably a thermoplastic film, a common protective film, decorative paper, cloth, and other materials commonly used for the outer package. A laser device, such as a laser marker, marks an area and recognizes a pattern that is difficult to copy to determine whether the outer package is genuine. The key point is that the outer package is punctured by laser, a processing trace is formed on the outer package, another processing trace is simultaneously formed on the corresponding position of the product on the inner side of the outer package or the surface of the inner package, the processing trace of the outer package and the processing trace of the product or the surface of the inner package are the same or have higher similarity, and the positions, the shapes and the textures of the outer package and the processing trace of the product or the surface of the inner package are the same/similar. And judging whether the outer package is the original package by identifying whether the processing trace of the outer package is consistent with the processing trace of the product or the surface of the inner package of the product. Wherein the texture includes depth, width, shape, etc.

The laser punctures the outer package and forms the carved pattern on the product or the inner package surface, so that the clear processing trace on the outer package can be obtained, the clear processing trace on the product or the inner package surface can be obtained, the observation and the comparison of human eyes are convenient, the carved pattern formed by points or/and discontinuous lines can be adopted, otherwise, the large-area hollow-out can be formed on the outer package, and the same or similar carved pattern is difficult to form. If the outer package is not broken through, only a trace is left on the outer package, which can be realized technically, however, the obtained trace is very simple and fixed, and is easy to imitate, and a clear trace is difficult to be left on the surface of the product or the inner package thereof, so that the similarity between the product and the inner package is difficult to judge through human eyes, and the core idea of the anti-counterfeiting anti-unsealing method is lost (the judgment can be carried out through human eyes).

Further, in order to improve the similarity between the processing traces of the outer package and the processing traces of the product or the surface of the inner package thereof, especially for the processing characteristics of the thermoplastic film, closed figures or line segments or longer line segments are not adopted, so that the thermoplastic film is easily melted by overheating during the laser processing, and more complete processing traces are difficult to form. Therefore, the engraving pattern formed by the dots or/and the discontinuous lines can be designed, and then the engraving pattern forms a profile formed by the dots or/and the discontinuous lines, such as a profile formed by the dots completely, or a profile formed by the discontinuous lines (short lines) completely, or a profile formed by the dots partially and the discontinuous lines (short lines).

Further, simply increasing the complexity of the pattern outline also makes it difficult to solve the problem that the pattern is easily imitated, and in order to improve the anti-counterfeiting performance, laser parameters for processing the engraved pattern are set, and the engraved pattern printed by the laser is not only different from the texture of other engraved patterns, but also has unique texture and is difficult to copy. The engraved pattern produced by laser machining using "special" laser parameters, which has a unique texture for each dot or/and discontinuous line, is difficult or costly to reproduce, thus minimizing the possibility of counterfeiting and technically blocking the possibility of counterfeiting.

In this embodiment, the dots or/and the discontinuous lines of the engraved pattern are regularly arranged or/and randomly arranged. Firstly, the carving pattern is designed through special software or conventional software, the carving pattern is designed according to a certain rule or at random according to a preset rule, and then the outline of the carving pattern is formed into an outline formed by points or/and discontinuous lines on the basis of the carving pattern, wherein the outline formed by the points or/and the discontinuous lines is also regularly arranged or randomly arranged according to the preset rule, and certainly, parts of the rules can be partially and randomly arranged. The method includes storing N bitmaps or partial pictures of the bitmaps by means of network acquisition, software generation, self-drawing of a management user and the like, and selecting one or more pictures from the N bitmaps or the partial pictures to process, wherein the processing includes but is not limited to scaling, rotation, beveling, twisting, perspective, deformation, turning, splicing, copying, overlapping and partial selection, and for example, two pictures are overlapped and combined, preferably partially overlapped and combined to form a required pattern. For example, a picture is selected for processing, the picture can be copied and then spliced or overlapped, or the picture is directly zoomed, rotated, obliquely cut, twisted, perspective, deformed, turned over and the like, so that the processed picture is completely different from the original picture.

And the laser parameters comprise one or more of Q frequency, marking/carving speed, energy/current, laser light-emitting time, jump delay and turning delay. The Q frequency is generated by the control card and provided for the laser, the number of pulses output by the laser per second is 20000 pulses output per second, for example, 20KHz represents that the Q frequency is smaller, and the obtained distance between processing shops is larger; the marking/engraving speed is the speed of the laser beam moving on the processed surface during laser processing, the smaller the speed is, the larger the energy density in unit time is, and the deeper and coarser the nick is; the energy/current comprises the duty ratio, release time and the like of the Q signal, and is mainly used for changing the Q signal or laser current to realize the control of the energy output of the laser; the laser light-emitting time comprises light-emitting time delay and light-off time delay of laser when a line is marked, and stored light-emitting time when a single point is marked; the jump delay is used for preparing time for switching different motion parameters of the galvanometer between two discontinuous lines and points; if a line with larger curvature exists in the middle of a line of which the laser continuously emits light during turning delay, the galvanometer needs a certain buffering time to correct the motion track of the galvanometer due to mechanical inertia.

For example, it is ensured that the thickness variation of the outline of the engraved pattern can be regular or random and that the repetition rate is extremely low.

By setting the carving pattern formed by points or/and discontinuous lines and setting laser parameters for processing the carving pattern, the random, unique, non-reproducible, permanent and hard-to-remove texture characteristics can be formed on the surface of the material by combining the points or/and the discontinuous lines and the laser parameters, and meanwhile, the human eye identification is facilitated; still further, the cost of the imitation is increased, eliminating the idea of the imitation.

In this embodiment, the engraved pattern is a text or a picture, and the font is a standard font or a custom font. The fonts comprise Chinese characters, numbers, letters, symbols and the like. The user-defined font is supported, and the font which belongs to the interior and is difficult to copy by others can be created through the user-defined font, so that the difficulty of copying and carving the content is increased.

In the present embodiment, after the laser processing is completed, the image data of the engraved trace is acquired. In order to enhance traceability and anti-counterfeiting performance, the carved patterns formed each time can be recorded in the modes of photographing, video recording, scanning and the like, so that the tracing and comparison can be carried out in the future. Preferably, a database can be established, the recorded carving patterns are recorded into the database, a comparison program is established again, the actual carving patterns are compared with the carving patterns in the database, and on the basis of naked eye identification, professionals are provided to call the carving patterns packaged for the first time for comparison, so that persuasion and authority are enhanced.

In this embodiment, the outer package may be a multi-layer outer package, and an engraved pattern with high similarity is formed on the outer package and the product or the inner package surface of each layer, so as to further improve the counterfeiting difficulty.

As shown in FIG. 2, the present invention provides a preferred embodiment of the anti-counterfeit tamper-evident method.

Firstly, generating a unique laser according to a set of parameter data consisting of at least one laser parameter, and secondly, the anti-counterfeiting tamper-evident method further comprises the steps of:

step S21, setting one group or multiple groups of parameter data for processing the carving pattern;

step S22, processing the carving pattern at least through a group of parameter data;

specifically, a set of parameter data or a plurality of sets of parameter data are set, and all parameter data or part of parameter data may be different between each set of parameter data. The essence of the method is that in the process of processing and carving patterns, one or more parameters of laser are changed, and the difference of textures of processing traces formed by the laser processed before and after is realized. The width, the depth and the shape of each line or point engraved by the laser are random, and the obtained engraving content can be obviously distinguished even if the same contour is continuously marked twice by the same machine.

The laser of different types can be obtained by changing one or more selected laser parameters and simultaneously changing non-selected laser parameters, so that tracks with different depths, tracks with different widths, tracks with different shapes and sizes, tracks with different surface traces and the like can be generated.

In this embodiment, the laser parameters are regularly set or/and randomly set, and the regular setting means that the numerical values of one or more laser parameters are regularly changed on the basis of a preset rule to form different sets of parameter data, so that the randomness of the engraved pattern is realized, meanwhile, effective interference can be performed, the overall complexity is improved, the laser processing is better facilitated, and the error rate of the processing process is prevented from being improved due to excessive large-range change.

In this embodiment, the laser parameter of each set of the parameter data gradually changes during the processing process until the laser parameter becomes a next set of preset parameter data. Specifically, a plurality of groups of parameter data are stored and arranged in sequence, and preferably, the laser can be carried out in a gradual change process through reasonable sequencing, so that the damage of a laser or the damage of a workpiece is caused by overlarge change; automatically or manually setting a total processing track according to the pattern, dividing the total processing track into a plurality of sections of sub-processing tracks according to a fixed distance or a random distance, configuring a group of parameter data for each section of sub-processing track, subsequently performing laser processing in the sub-processing tracks, and performing processing by adopting laser corresponding to the configured group of parameter data, wherein in the processing process, the laser parameters of the current group of parameter data gradually change and transition to the next group of parameter data in the processing process; of course, there are two possibilities, the first is to fade the previous set of parameter data to the next set of parameter data, or to randomly fade the previous set of parameter data to the next set of parameter data, and then to directly skip to the current set of parameter data.

As shown in fig. 3 and 4, the present invention provides a preferred embodiment of the anti-counterfeit tamper-evident method for improving anti-counterfeit property.
