Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting product technology, and in particular to an anti-counterfeiting preparation process, electronic device and storage medium based on air blowing development. Background Technology

[0002] Currently, flocked anti-counterfeiting labels are widely used in the field of product anti-counterfeiting. Traditional anti-counterfeiting methods mainly rely on subtle differences in patterns, colors, or textures to distinguish genuine products from counterfeits. However, with the continuous improvement of counterfeiting technology, these anti-counterfeiting labels based on macroscopic visual features are easily cracked by high-precision scanning and copying equipment, leading to a decrease in anti-counterfeiting reliability. For example, through advanced image acquisition and flocking processes, counterfeiters can accurately replicate the appearance features of the label, making it difficult for consumers or inspectors to distinguish genuine from counterfeits with the naked eye. Therefore, there is an urgent need for a new method for preparing flocked anti-counterfeiting labels that can maintain macroscopic consistency while constructing differentiated anti-counterfeiting features at the microscopic level, thereby increasing the difficulty of counterfeiting. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an anti-counterfeiting preparation process, electronic equipment, and storage medium based on air blowing development, which can improve the anti-counterfeiting effect of products.

[0004] In a first aspect, this application provides an anti-counterfeiting preparation process based on air blowing development, comprising:

[0005] Receive products that require printing anti-counterfeiting labels, and apply flocking adhesive to the target surface of the products; wherein the target surface includes a preset first area and a second area;

[0006] Cover the second region of the target surface with a shield to isolate the first region and the second region;

[0007] The first fibers are electrostatically sprayed onto the target surface to make the first fibers adhere to the first area.

[0008] Remove the shielding cover from the target surface;

[0009] The second flock is electrostatically sprayed onto the target surface to make the second flock adhere to the second region; wherein the first flock and the second flock have the same flock color and flock density, and the first flock and the second flock have different hardness.

[0010] The first and second fibers on the target surface are dried and shaped at a preset first temperature to form a flocked anti-counterfeiting mark on the target surface.

[0011] The anti-counterfeiting preparation process based on air blowing development according to the first aspect of this application has at least the following beneficial effects: First, a product to be printed with an anti-counterfeiting label is received. A flocking adhesive is coated on its target surface, which includes a first area and a second area. Then, a masking cover is placed over the second area to isolate the two areas. First flocking is then adhered to the first area by electrostatic spraying. After removing the masking cover, second flocking is attached to the second area by electrostatic spraying. The first and second flocking have the same color and flocking density but different hardness. Finally, the label is dried and set at a preset first temperature to form a flocked anti-counterfeiting label. This method uses flocking with different hardness in different areas of the same label, making the anti-counterfeiting label appear consistent macroscopically, while creating differentiated features at the microscopic level due to the difference in flocking hardness. Because traditional anti-counterfeiting methods rely on subtle differences in patterns that are easily counterfeited, this method uses hardness—a physical property that is difficult to replicate visually—to create anti-counterfeiting points. Counterfeiters cannot accurately simulate the difference in hardness simply by replicating the appearance. In the process of verifying authenticity, the first and second fibers are blown on. The difference in the bending modulus of the two fibers results in different degrees of bending under the air load, forming an overall pattern color difference. The degree of tilt caused by the difference in the hardness of the two fibers is used to determine authenticity. At the same time, the anti-counterfeiting mark can be restored to its original state by blowing air in the opposite direction or by manually smoothing it, thus improving the anti-counterfeiting effect of the product.

[0019] According to some embodiments of the first aspect of this application, after the step of electrostatically spraying the first fibers onto the target surface, the method further includes:

[0020] Acquire a second image of the target surface after the flocking operation in the first region is completed;

[0023] According to the recoating parameters, the sub-regions with deviations are subjected to targeted recoating of the first fuzz.

[0024] According to some embodiments of the first aspect of this application, prior to the step of drying and shaping the first and second fibers on the target surface at a preset first temperature, the method further includes:

[0027] The smoothness of the nap on the target surface is obtained based on the third image.

[0028] When the smoothness of the fluff meets the preset smoothness standard, the fluff removal process is stopped.

[0030] Blow on the fluffy texture of the anti-counterfeiting label to be verified;

[0031] When the target anti-counterfeiting mark is blown, the first state of the fluff in the first area and the second state of the fluff in the second area are obtained;

[0032] Based on the first state and the second state of the fluff, the authenticity identification result corresponding to the target anti-counterfeiting mark is obtained.

[0033] According to some embodiments of the first aspect of this application, obtaining the first state of the down in the first region and the second state of the down in the second region includes:

[0034] Acquire a dynamic image sequence of the target anti-counterfeiting mark under the action of airflow; wherein, the dynamic image sequence at least covers the complete process of the fluff from its initial position to a stable state;

[0035] Based on the dynamic image sequence, the positions of the first region and the second region are identified, and the tip feature points of the villi in the first region and the second region are determined, so as to perform feature tracking on the state of the villi.

[0036] Based on the positional changes of each tip feature point in the dynamic image sequence, the first state of the villi in the first region and the second state of the villi in the second region are determined; wherein, the first state of the villi is used to characterize the average tilt angle of the villi in the first region, and the second state of the villi is used to characterize the average tilt angle of the villi in the second region.

[0058] Currently, flocked anti-counterfeiting labels are widely used in the field of product anti-counterfeiting. Traditional anti-counterfeiting methods mainly rely on subtle differences in patterns, colors, or textures to distinguish genuine products from counterfeits. However, with the continuous improvement of counterfeiting technology, these anti-counterfeiting labels based on macroscopic visual features are easily cracked by high-precision scanning and copying equipment, leading to a decrease in anti-counterfeiting reliability. For example, through advanced image acquisition and flocking processes, counterfeiters can accurately replicate the appearance features of the label, making it difficult for consumers or inspectors to distinguish genuine from counterfeits with the naked eye. Therefore, there is an urgent need for a new method for preparing flocked anti-counterfeiting labels that can maintain macroscopic consistency while constructing differentiated anti-counterfeiting features at the microscopic level, thereby increasing the difficulty of counterfeiting.

[0059] Based on this, this application provides an anti-counterfeiting preparation process, electronic device and storage medium based on air blowing development to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0060] Firstly, referring to Figure 1 and Figure 2 This application provides an anti-counterfeiting preparation process based on air blowing development, which includes, but is not limited to, the following steps:

[0061] Step S110: Receive the product for which anti-counterfeiting labels need to be printed, and apply flocking adhesive to the target surface of the product; wherein, the target surface includes a preset first area and a second area.

[0062] Step S120: Cover the second area of ​​the target surface with a shield to isolate the first and second areas.

[0063] Step S130: The first fibers are electrostatically sprayed onto the target surface to make the first fibers adhere to the first area.

[0064] Step S140: Remove the masking mask from the target surface.

[0065] Step S150: The second flock is electrostatically sprayed onto the target surface to make the second flock adhere to the second region; wherein the first flock and the second flock have the same flock color and flocking density, and the first flock and the second flock have different hardness.

[0066] Step S160: Dry and shape the first and second flocks on the target surface at a preset first temperature to form flocked anti-counterfeiting marks on the target surface.

[0067] In steps S110 to S160, a product 130 to be printed with an anti-counterfeiting label is first received. Flocking adhesive is applied to its target surface, which includes a first area 110 and a second area 120. Then, a masking cover 140 is placed over the second area 120 to isolate the two areas. First flocking fibers are then attached to the first area 110 by electrostatic spraying. After removing the masking cover 140, second flocking fibers are attached to the second area 120 by electrostatic spraying. The first and second flocking fibers 150 and 160 have the same color and flocking density but different hardness. Finally, the product is dried and set at a preset first temperature to form a flocked anti-counterfeiting label 100. This method uses flocking fibers with different hardness in different areas of the same label, making the anti-counterfeiting label appear consistent macroscopically, while creating differentiated features at the microscopic level due to the difference in flocking hardness. Because traditional anti-counterfeiting methods rely on subtle differences in patterns that are easily counterfeited, this method uses hardness—a physical property that is difficult to replicate visually—to create anti-counterfeiting points. Counterfeiters cannot accurately simulate the hardness difference simply by replicating the appearance. In the process of verifying authenticity, the first and second fibers 150 and 160 need to be blown on. By utilizing the difference in the bending modulus of the two fibers, the different degrees of bending under the blowing load create an overall pattern color difference. The degree of tilt caused by the difference in the hardness of the two fibers is used to determine authenticity. At the same time, the anti-counterfeiting mark can be restored to its original state by blowing air in the opposite direction or by manually smoothing it, thus improving the anti-counterfeiting effect of the product.

[0068] It should be noted that the material of the first pile is either nylon or polyester, and the material of the second pile is either nylon or polyester. The characteristics are as follows: the color difference between the first and second piles is considered to be the same or similar when ΔE < 2.0; the length of the first and second piles is 1.5-5.0 mm, the length difference between the two piles is no more than 0.3 mm, and the diameter is 0.05-0.6 mm. The flocking density (i.e., pile area ratio) of the first and second piles is 40%-60%, where the pile area ratio of the second pile is greater than the pile area ratio of the first pile + 5%. Furthermore, the adhesive application rate for the first and second regions is 100-300 g / m², and the adhesive application rate for the second region is 50%-80% of the adhesive application rate for the first region.

[0069] Reference Figure 3 It is understood that step S120 may include, but is not limited to, the following steps:

[0070] Step S210: Obtain the first image of the target surface.

[0071] Step S220: Based on the first image, determine the first contour features of the first region and the second contour features of the second region.

[0072] Step S230: Adjust the position and angle of the masking mask according to the second contour features, and cover the second area with the masking mask.

[0073] In steps S210 to S230, a first image of the target surface is first acquired using an image acquisition device. Based on this image, the first contour features of the first region 110 and the second contour features of the second region 120 are analyzed and identified. For example, when the contour of the second region 120 is an irregular curve, the system calculates the required position coordinates and angle parameters of the masking cover based on its contour features. Then, the multi-axis robotic arm is controlled to grasp the masking cover 140 corresponding to the irregular contour. The spatial position and tilt angle of the masking cover are dynamically adjusted according to the calculated parameters, and finally the masking cover 140 is accurately covered in the second region 120. For example, when the second region 120 is an irregular star-shaped contour, the multi-axis robotic arm can adjust the edge of the masking cover 140 according to the coordinates of the star vertex and the edge line in the first image to avoid insufficient masking causing the first fuzz to overflow into the second region 120, or excessive masking causing the boundary of the second region 120 to be missing. This visual positioning-based adjustment mechanism ensures the accurate decomposition of the two-area flocking spray, allowing the first and second flocks to be precisely distributed within their respective areas. This ensures the difference in flock hardness in the subsequent flocking anti-counterfeiting label 100, thereby improving the product's anti-counterfeiting effect.

[0074] Reference Figure 3 It is understood that the shield 140 is a heat insulation shield; after step S130, the following steps may also be included, but are not limited to:

[0075] Step S310: Pre-dry the first area of ​​the target surface at a preset second temperature to cure the flocking adhesive in the first area and fix the first flock in the first area; wherein the second temperature is lower than the first temperature.

[0076] In step S310, after the electrostatic spraying of the first flock 150 onto the first region 110 is completed, a heat shield is used to protect the second region 120 to prevent heat conduction to this region during the pre-drying process. Subsequently, a preset second temperature is applied to the first region 110 for pre-drying treatment. This temperature is lower than the subsequent overall drying temperature, ensuring that the flocking adhesive in the first region 110 reaches a semi-cured state, thus firmly fixing the first flock 150 to this region. This method prevents the adhesive in the first region 110 from sticking together during the subsequent spraying of the second flock 160, while also preventing premature curing of the adhesive in the second region 120 due to high temperature. This improves the controllability of the anti-counterfeiting label's microstructure, allowing flocks of different hardness to form clear boundaries in corresponding areas, and strengthening the reliability of anti-counterfeiting features based on the differences in flock material.

[0077] It is understandable that after spraying the first pile in step S130, the following steps may be included, but are not limited to:

[0078] Step S410: Obtain a second image of the target surface after the first area flocking operation is completed.

[0079] Step S420: Based on the second image, identify the velvet distribution density in each sub-region of the first region.

[0080] Step S430: When the fiber distribution density in any sub-region is lower than the preset density threshold, the recoating parameters are determined based on the deviation between the fiber distribution density and the preset density threshold.

[0081] Step S440: Based on the recoating parameters, perform targeted recoating of the first fuzz on the sub-regions with deviations.

[0082] In steps S410 to S440, after the electrostatic spraying of the first flock onto the first region 110 is completed, a second image of the target surface is acquired using an image acquisition device. Based on image analysis technology, the flock distribution density of each sub-region within the first region 110 is identified. When the flock density of a certain sub-region is detected to be lower than a preset threshold, the system automatically calculates the deviation between the density and the threshold and dynamically generates recoating parameters accordingly. Subsequently, the electrostatic spraying device is controlled to perform targeted recoating on the sub-region. These steps ensure the uniformity of the flock distribution, thereby enhancing the uniformity of the anti-counterfeiting label's appearance.

[0083] Reference Figure 4 It is understood that, prior to step S160, the following steps may also be included, but are not limited to:

[0084] Step S510: Perform a lint removal process on the target surface to remove unadhesive accumulated lint from the surfaces of the first and second regions; wherein the lint removal process includes at least one of airflow blowing, soft brush cleaning, or electrostatic adsorption.

[0085] Step S520: Obtain the third image of the target surface after the lint removal operation is completed.

[0086] Step S530: Obtain the smoothness of the pile on the target surface based on the third image.

[0087] Step S540: When the smoothness of the pile meets the preset smoothness standard, stop the pile removal process.

[0088] In steps S510 to S540, before drying and shaping, the target surface is first treated with airflow blowing, soft brush cleaning, or electrostatic adsorption to remove unadhesive accumulated lint. Then, a third image of the processed surface is acquired, and the lint smoothness of the target surface is calculated using image analysis technology. This smoothness is compared with a preset standard; if it meets the standard, the removal operation stops. These steps prevent appearance defects and interference with anti-counterfeiting features caused by residual lint, thus improving the reliability of the anti-counterfeiting label.

[0089] Reference Figure 4 It is understood that the anti-counterfeiting preparation process based on air blowing development provided in this application also includes an anti-counterfeiting identification method for flocked anti-counterfeiting labels. This anti-counterfeiting identification method may include, but is not limited to, the following steps:

[0090] Step S610: Blow the fluff on the target anti-counterfeiting label to be verified.

[0091] Step S620: When the target anti-counterfeiting label is blown, obtain the first state of the fluff in the first area and the second state of the fluff in the second area.

[0092] Step S630: Based on the first state and the second state of the lint, obtain the authenticity identification result corresponding to the target anti-counterfeiting mark.

[0093] In steps S610 to S630, airflow is applied to the target anti-counterfeiting label to agitate the fibers, and the first state of the fibers in the first region and the second state of the fibers in the second region are simultaneously collected, such as the difference in appearance between soft fibers lying down and hard fibers standing upright. By analyzing the characteristic differences between the two states, such as tilt angle and recovery speed, and comparing them with preset standards, the authenticity determination result is output. In the above steps, the authenticity of the product is determined by the state differences agitated by airflow, which improves the concealment of authenticity identification and breaks through the traditional anti-counterfeiting label's limitation of only being able to distinguish authenticity from a macroscopic and static perspective, thus improving the anti-counterfeiting capability of the anti-counterfeiting label.

[0094] It is understood that step S620 may include, but is not limited to, the following steps:

[0095] Step S710: Obtain a dynamic image sequence of the target anti-counterfeiting mark under the action of airflow; wherein the dynamic image sequence covers at least the complete process of the fluff from the initial position to the stable state.

[0096] Step S720: Based on the dynamic image sequence, identify the positions of the first region and the second region, and determine the tip feature points of the fluff in the first region and the second region to perform feature tracking on the state of the fluff.

[0097] Step S730: Based on the positional changes of each tip feature point in the dynamic image sequence, determine the first state of the fluff in the first region and the second state of the fluff in the second region; wherein, the first state of the fluff is used to characterize the average tilt angle of the fluff in the first region, and the second state of the fluff is used to characterize the average tilt angle of the fluff in the second region.

[0098] In steps S710 to S730, a dynamic image sequence of the target anti-counterfeiting label under airflow is acquired, covering the entire process of the fluff going from static to dynamic and then back to stability. Based on image recognition technology, the first and second regions are located, and feature points of the fluff tips in both regions are extracted. By analyzing the positional change trajectory of the feature points in each frame of the image, the average tilt angle of the fluff in the first region (i.e., the first state of the fluff) and the average tilt angle of the fluff in the second region (i.e., the second state of the fluff) are calculated. Through dynamic image sequence and feature point tracking, the microscopic physical characteristics of the different hardness of the first and second fluffs are transformed into quantifiable angular parameter differences, improving the objectivity and accuracy of anti-counterfeiting determination.

[0099] Specifically, in step S730, the average tilt angle of the fluff can be represented by the flexural modulus. The support span L (distance between the two support points of the specimen), specimen width b, and specimen thickness h are obtained through a dynamic image sequence. The flexural load F corresponding to the airflow is also obtained, and the flexural deflection δ corresponding to the flexural load is obtained by looking up a table. The flexural modulus E is then calculated using the following formula. f (MPa):

[0100]

[0101] During the flocking process, the bending modulus of the first flock in the first region is 1.5-2.5 GPa, and the bending modulus of the second flock is 2.5-3.5 GPa. The difference between the two bending moduli is more than 1.0 GPa, so that the difference between the two regions can be better reflected in subsequent anti-counterfeiting verification.

[0102] It is understood that step S630 may include, but is not limited to, the following steps:

[0103] Step S810: When the tilt degree corresponding to the first state of the fluff is greater than or equal to the tilt degree corresponding to the second state of the fluff, the product corresponding to the target anti-counterfeiting mark is determined to be a counterfeit.

[0104] Step S820: When the tilt degree corresponding to the first state of the fluff is less than the tilt degree corresponding to the second state of the fluff, the product corresponding to the target anti-counterfeiting mark is determined to be genuine.

[0105] In steps S810 to S820, in one embodiment, the hardness of the first pile is less than that of the second pile. When airflow is applied to the target anti-counterfeiting mark, the first state of the pile in the first region and the second state of the pile in the second region are calculated using a dynamic image sequence. Then, the tilt degrees of the two are numerically compared. If the tilt degree of the first region is greater than or equal to that of the second region, it is determined to be a counterfeit; if the tilt degree of the first region is less than that of the second region, it is determined to be a genuine product. This transforms the microscopic feature of "different hardness" into a detectable indicator of "different tilt degrees." For example, in genuine products, the soft first pile is more likely to collapse in airflow, while the hard second pile is more likely to stand upright. Counterfeit products, unable to accurately reproduce the difference in pile hardness, are prone to reversing the tilt degree or having insufficient difference. This improves the objectivity and reliability of anti-counterfeiting identification.

[0106] In another embodiment, the first pile hardness can be selected to be greater than the second pile hardness. If the tilt of the first region is greater than that of the second region, it is determined to be a genuine product; if the tilt of the first region is less than or equal to that of the second region, it is determined to be a counterfeit product. The selection of the pile material for the first and second regions is not limited in this application. Specifically, the tilt of the pile in the first state and the tilt of the pile in the second state can be reflected by the flexural modulus of the two regions. The difference between the flexural modulus of the first region and the flexural modulus of the second region is used to determine the difference in the hardness of the first and second pile.

[0107] In a second aspect, this application also provides an electronic device, comprising: at least one memory; at least one processor; at least one program; the program being stored in the memory, and the processor executing the at least one program to implement the anti-counterfeiting preparation process based on air blowing development as described in any embodiment of the first aspect.

[0108] In this electronic device, a product requiring anti-counterfeiting label printing is first received. A flocking adhesive is applied to the target surface, which includes a first area and a second area. A shield is then placed over the second area to isolate the two areas. First flocking fibers are then attached to the first area using electrostatic spraying. After removing the shield, second flocking fibers are attached to the second area using electrostatic spraying. The first and second flocking fibers have the same color and flocking density but different hardness. Finally, the product is dried and set at a preset first temperature to form the flocked anti-counterfeiting label. This method uses flocking fibers with different hardness in different areas of the same label, making the anti-counterfeiting label appear consistent macroscopically, while creating differentiated features at the microscopic level due to the difference in flocking hardness. Since traditional anti-counterfeiting methods rely on subtle differences in patterns that are easily counterfeited, this method uses hardness—a physical property difficult to replicate visually—to construct anti-counterfeiting points. Counterfeiters cannot accurately simulate the difference in hardness simply by copying the appearance.
