Description

Technical Field

[0001] The present invention relates to the field of anti-channelling and traceability technology, specifically to an anti-channelling method by forming an indestructible invisible anti-channelling code inside a glass packaging material. The method is suitable for the circulation management of glass bottled products such as food, medicine, health products, cosmetics, and alcohol. Background Art

[0002] In industries such as fast-moving consumer goods and pharmaceuticals, cross-regional sales by agents is a common problem that disrupts market order. Traditional methods to prevent cross-border sales often involve placing clear codes on the packaging surface (such as laser engraving codes and QR code labels), but this has the following drawbacks:

[0003] Easy to destroy: Distributors can remove the surface anti-channeling code by grinding, chemical corrosion, tearing off the label, etc., making it impossible for the brand to track the flow of products;

[0004] The contradiction between destructibility and marketability: The existence of the surface code depends on the integrity of the packaging. Once the code is damaged, the packaging must be destroyed. Packaging damage directly affects product sales. Agents often take advantage of this loophole to divert goods.

[0005] Insufficient tracking accuracy: Existing systems mostly rely on manual entry or simple regional binding, lacking the unique binding of anti-interference codes and dealer regions and automated tracking logic.

[0006] In the existing technology, although there are internal coding technologies (such as micro-engraving under the glass surface), they do not solve the following problems:

[0007] If the coding depth is insufficient or it contacts the surface, it can still be removed by polishing or other means;

[0008] Without deep integration with dealer regional information, accurate identification of channeling behavior cannot be achieved;

[0009] There is a lack of anti-tampering mechanism design to prevent "destroying the anti-channeling code will destroy the marketability of the product."

[0010] Therefore, there is an urgent need for an anti-channeling method that hides the anti-channeling code inside the glass wall, is uniquely bound to the dealer area, and cannot be destroyed by the agent without affecting the sales of the product. Summary of the Invention

[0011] The purpose of the present invention is to provide an invisible anti-channelling method based on glass materials, in which an anti-channelling code is printed in the middle of the glass wall without contacting the surface. Destroying the anti-channelling code requires destroying the internal structure of the bottle, resulting in damage to the sealing and appearance of the product, making it unsaleable, thereby curbing the motivation of agents to commit destructive behavior; the anti-channelling code corresponds one-to-one with the authorized sales area of the dealer, and "one code one area" tracking is achieved through the anti-channelling management system to prevent identity forgery after channelling; the anti-channelling code is invisible to the naked eye and is only visible through a specific light source, preventing agents from discovering it in advance and causing targeted destruction.

[0012] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an invisible anti-channeling method based on glass materials, comprising an anti-channeling management system, a production coding system, a laser coding machine, glass packaging materials and detection equipment; wherein:

[0013] A laser coding machine is used to form an invisible anti-channeling code in the middle of the bottle wall of the glass packaging material, which is uniquely bound to the dealer area. The anti-channeling code meets the following requirements:

[0014] Invisible to the naked eye and non-specific light sources, visible only by specific light sources;

[0015] Located inside the bottle wall and not touching the surface, agents cannot remove or tamper with it without destroying the integrity of the bottle (affecting product sales).

[0016] As a further improvement to the technical solution of the present invention, the anti-channelling management system includes:

[0017] The dealer area information management module is used to store each dealer's authorized sales area, dealer code and corresponding anti-channeling code generation rules;

[0018] The cross-selling tracking module is used to bind the anti-cross-selling code with product logistics information and dealer area information. By scanning the code to identify the authorized area corresponding to the anti-cross-selling code, it is determined whether there is cross-regional sales behavior.

[0019] As a further improvement to the technical solution of the present invention, the production coding system implements anti-code coding through the following steps:

[0020] a. Obtain the unique anti-channeling code associated with the dealer region from the anti-channeling management system;

[0021] b. Control the laser coding machine to process the anti-channeling code into the middle of the glass bottle wall, forming an invisible pattern composed of light-absorbing dot matrix.

[0022] As a further improvement to the technical solution of the present invention, the laser coding machine focuses a 355nm ultraviolet laser beam on the interior of the glass material. By adjusting the pulse parameters (wavelength, power, and pulse width), the laser energy forms an irreversible molecular structure modification area in the middle of the bottle wall. The modified area has absorption characteristics for light in a specific wavelength band, forming an optical contrast difference with the surrounding material.

[0023] As a further improvement to the technical solution of the present invention, the coding depth of the laser coding machine is controlled by the pulse duration, and the coding position is 0.3-2 mm away from the glass surface, ensuring that the anti-channeling code is displayed in the middle of the bottle wall and is not exposed to the outer surface.

[0024] As a further improvement to the technical solution of the present invention, the key parameters of the laser coding machine are:

[0025] Wavelength: 355nm;

[0026] Pulse energy: >35μJ@15kHz, ensuring that the energy is focused enough to destroy the glass molecular structure but not penetrate the bottle wall;

[0027] Pulse width (FWHM): ≤1.1ns, achieving molecular structure modification with nanometer-level precision.

[0028] As a further improvement to the technical solution of the present invention, the detection equipment is a UV detection device equipped with a 355nm ultraviolet light source, which irradiates the bottle wall to form a light-dark contrast between the light-absorbing area of the anti-channeling code and the unmodified area, thereby revealing the anti-channeling code pattern.

[0029] As a further improvement to the technical solution of the present invention, the difficulty of destroying the anti-channeling code is strongly related to the integrity of the bottle body: if the anti-channeling code is removed or tampered with, the internal structure of the bottle wall needs to be destroyed, resulting in cracks in the bottle body, abnormal light transmittance and other defects that affect the sealing or appearance of the product, making the product unable to be sold normally.

[0030] As a further improvement to the technical solution of the present invention, the decision logic of the cross-selling tracking module is as follows:

[0031] When the authorized area corresponding to the anti-channeling code read by the detection equipment is inconsistent with the actual sales area of the product, it is marked as channeling behavior, and the channeling path and responsible dealer information are recorded.

[0032] As a further improvement to the technical solution of the present invention, the binding relationship between the anti-channelling code and the dealer area is unique in the anti-channelling management system: each anti-channelling code corresponds to and only corresponds to one authorized sales area, and the binding relationship cannot be modified after the production coding.

[0033] The present invention has the following beneficial effects:

[0034] The anti-channeling code is indestructible: The anti-channeling code is stamped in the middle of the glass wall, not touching the surface. Destroying the anti-channeling code requires damaging the internal structure of the bottle, resulting in damage to the product's sealing and appearance, making it unsaleable. This effectively deters agents from sabotaging the code.

[0035] Unique regional binding: The anti-channeling code corresponds one-to-one with the dealer's authorized sales area. Through the anti-channeling management system, "one code, one area" tracking is achieved to prevent identity forgery after channeling;

[0036] Invisibility and Specific Detection: The anti-tampering code is invisible to the naked eye and can only be revealed by a specific light source, preventing agents from discovering it in advance and then sabotaging it. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of various embodiments may be combined with each other, but only on the basis that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions contradicts or cannot be implemented, it shall be deemed that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this disclosure.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Reference Figure 1 and Figure 2The present invention provides a technical solution: an invisible anti-channeling method based on glass materials, including an anti-channeling management system, a production coding system, a laser coding machine, glass packaging materials and detection equipment; wherein:

[0046] A laser coding machine is used to form an invisible anti-channeling code in the middle of the bottle wall of the glass packaging material, which is uniquely bound to the dealer area. The anti-channeling code meets the following requirements:

[0047] Invisible to the naked eye and non-specific light sources, visible only by specific light sources;

[0048] Located inside the bottle wall and not touching the surface, agents cannot remove or tamper with it without destroying the integrity of the bottle (affecting product sales).

[0049] Specifically, in this embodiment, the anti-channeling management system includes:

[0050] The dealer area information management module is used to store each dealer's authorized sales area, dealer code and corresponding anti-channeling code generation rules (such as area code + product batch + random code combination);

[0051] The cross-selling tracking module binds the anti-cross-selling code to product logistics information and distributor region information. By scanning the code to identify the authorized region corresponding to the anti-cross-selling code, the module can determine whether cross-selling occurs. The cross-selling tracking module receives the anti-cross-selling code from the detection device, matches the preset authorized region with the actual sales area, determines cross-selling activity, and records the route.

[0052] Specifically, in this embodiment, the production coding system implements anti-code coding through the following steps:

[0053] a. Obtain the unique anti-channeling code associated with the dealer region from the anti-channeling management system;

[0054] b. Control the laser coding machine to process the anti-channeling code into the middle of the glass bottle wall, forming an invisible pattern composed of light-absorbing dot matrix.

[0055] Specifically, in this embodiment, the laser coding machine focuses a 355nm ultraviolet laser beam on the interior of the glass material. By adjusting the pulse parameters (wavelength, power, and pulse width), the laser energy forms an irreversible molecular structure-modified region in the middle of the bottle wall. The modified region has absorption characteristics for light in a specific wavelength band, forming an optical contrast difference with the surrounding material. It should be noted that the high-energy ultraviolet laser pulse (pulse width ≤ 1.1ns) is focused on the interior of the glass, destroying the silicon-oxygen bond through the multiphoton absorption effect, forming a modified region with a density difference. The region's absorption rate for 355nm ultraviolet light is increased by 40%-60%, forming a light-dark contrast with the unmodified area.

[0056] Specifically, in this embodiment, the laser coding depth is controlled by pulse duration, and the coding position is 0.3-2 mm from the glass surface, ensuring that the anti-channeling code is displayed suspended in the middle of the bottle wall and not exposed on the outer surface. It should be noted that the anti-channeling code's physical characteristics are: it is displayed suspended in the middle of the bottle wall (0.3-2 mm from the surface), composed of nanoscale light-absorbing dots, and does not contact the glass surface. To damage it, it must penetrate at least 0.3 mm of the glass layer, causing cracks in the bottle or abnormal light transmittance.

[0057] Specifically, in this embodiment, the key parameters of the laser coder are:

[0058] Wavelength: 355nm;

[0059] Pulse energy: >35μJ@15kHz, ensuring that the energy is focused enough to destroy the glass molecular structure but not penetrate the bottle wall;

[0060] Pulse width (FWHM): ≤1.1ns, achieving molecular structure modification with nanometer-level precision.

[0061] Specifically, in this embodiment, the detection device is a UV detection device equipped with a 355nm ultraviolet light source, which irradiates the bottle wall to form a light-dark contrast between the light-absorbing area of the anti-channeling code and the unmodified area, thereby revealing the anti-channeling code pattern.

[0062] Specifically, in this embodiment, the difficulty of destroying the anti-tampering code is closely related to the integrity of the bottle body: if the anti-tampering code is removed or tampered with, the internal structure of the bottle wall needs to be destroyed, resulting in cracks in the bottle body, abnormal light transmittance, and other defects that affect the sealing or appearance of the product, making the product unable to be sold normally.

[0063] Specifically, in this embodiment, the decision logic of the channeling tracking module is:

[0064] When the authorized area corresponding to the anti-channeling code read by the detection equipment is inconsistent with the actual sales area of the product, it is marked as channeling behavior, and the channeling path and responsible dealer information are recorded.

[0065] Specifically, in this embodiment, the binding between the anti-channeling code and the dealer region is unique within the anti-channeling management system: each anti-channeling code corresponds to one and only one authorized sales region, and this binding cannot be modified after the code is assigned. It should be noted that each anti-channeling code is uniquely bound to the dealer region at the time of production, and this binding cannot be tampered with, ensuring "one code, one region" traceability.

[0066] Reference Figure 2 , specifically, the specific operation process of the present invention:

[0067] Step S1, parameter calibration: manually adjust the focal length of the laser head so that the light spot is focused on the middle of the bottle wall (for example, 0.5 mm from the surface), avoiding contact with the inner and outer surfaces;

[0068] Step S2, system linkage: the production coding system obtains the anti-channeling code containing regional information from the anti-channeling management system and confirms that the laser machine is properly connected to the industrial control platform;

[0069] Step S3, dynamic coding: After the product triggers the photoelectric switch, the laser machine scans the middle of the bottle wall with a high-frequency pulse laser (15kHz frequency), forming an anti-channeling code consisting of 200-500 light absorption points (such as a combination of "region code + product ID");

[0070] Step S4, channel-counterfeiting detection: The terminal uses UV detection equipment to illuminate the bottle wall, revealing the anti-channelling code and uploading it to the anti-channelling management system, comparing the authorized area with the sales area to determine whether channel-counterfeiting has occurred.

[0071] Working principle:

[0072] Coding preparation: Generate a unique anti-channeling code bound to the dealer area in the anti-channeling management system, set the laser coding machine parameters (wavelength 355nm, pulse energy 35μJ or above) through the production coding system, and adjust the focal length so that the coding position is 0.3-2mm in the middle of the glass wall (not touching the surface).

[0073] Dynamic coding: When glass products flow through the production line, the photoelectric switch triggers the laser coding machine, which destroys the internal molecular structure of the glass through high-frequency ultraviolet laser pulses, forming an invisible anti-channeling code composed of light-absorbing dot matrix (invisible to the naked eye).

[0074] Cross-selling detection: The terminal uses a detection device equipped with a 355nm ultraviolet light source to illuminate the bottle wall. The light-absorbing area of the anti-cross-selling code contrasts with the surrounding transparent glass. The system reads the code and matches it with the authorized area to determine whether cross-regional sales are taking place.

[0075] Anti-destruction mechanism: The anti-channeling code is located inside the glass. To destroy it, the glass layer must be penetrated, causing cracks in the bottle or failure of the seal, making the product unsaleable. Agents have no motivation to destroy it, eliminating tampering with the channeling code from a physical and economic perspective.

[0076] The present invention has the following advantages:

[0077] Substantially improved anti-destruction capabilities:

[0078] The anti-channeling code is located 0.3-2mm inside the glass. To destroy it, the glass layer must be penetrated, causing the bottle's sealing to fail (such as wine leakage) or visible defects in the appearance. Agents cannot remove it without affecting sales, thus eliminating sabotage from an economic motivation.

[0079] Accurate tracking of counterfeit goods:

[0080] Through the "anti-counterfeiting code - regional unique binding" and automated judgment logic, brands can locate the source of counterfeit goods in real time, and the accuracy of counterfeit goods identification is increased to more than 99%.

[0081] Low-cost and efficient coding:

[0082] It uses UV laser coding without consumables, with a coding speed of 100 pieces per minute and a single code cost of less than 0.01 yuan, which is significantly lower than traditional labels or surface engraving technology.

[0083] Example 1: Implementation of Anti-channelling Management System and Regional Binding

[0084] 1.1 Dealer area information initialization

[0085] The brand owner performs the following operations in the dealer area information management module of the anti-channelling management system:

[0086] Enter the authorization information for Distributor A (General Agent for North China): Authorized sales areas are Beijing, Tianjin, and Hebei, with the preset region code "HB001." The anti-smuggling code generation rule is set to "region code (3 digits) + product category (2 digits) + production year and month (4 digits) + serial number (4 digits)." For example, the first product of alcoholic beverages produced in April 2025 would have an anti-smuggling code of "HB001-LS-202504-0001," where "LS" represents alcoholic beverages.

[0087] Enter the authorization information of distributor B (general agent in East China): regional code "HD002", anti-coding rule is "HD002-YZ-202504-0001", "YZ" represents the beverage category.

[0088] The system automatically verifies the uniqueness of the regional code, prohibits repeated authorization in the same region, and ensures that each anti-channeling code is uniquely bound to the dealer region.

[0089] 1.2 Decision Logic of Channel-Falling Tracking Module

[0090] When the terminal sales point reads the anti-channeling code "HB001-LS-202504-0001" through the UV detection device and uploads it to the system, the channeling tracking module determines the following steps:

[0091] Parse the first three digits of the anti-channeling code "HB001" and match the preset authorized area to "North China";

[0092] Combined with the detection device's location IP (such as "Shanghai"), it is determined that the product appears in an unauthorized area (East China);

[0093] The system automatically marks it as a parallel trading behavior and records detailed information: including the category of the parallel trading product (alcohol), production year and month (April 2025), serial number (0001), responsible distributor (Distributor A) and the parallel trading route (from North China to East China).

[0094] Example 2: Laser coding key process and parameter verification

[0095] 2.1 Coding depth and position control

[0096] Taking a glass bottle with a wall thickness of 5mm as an example, the coding depth is set to 1.0mm from the outer surface (located at the middle 20% thickness of the bottle wall). The specific debugging steps are as follows:

[0097] Use a laser micrometer to accurately measure the glass wall thickness, manually adjust the laser head focus, and use a CCD camera to monitor the light spot position in real time to ensure that the focus is at the preset depth and does not touch the inner and outer surfaces of the glass.

[0098] Key pulse parameter settings are based on glass material properties (silicon-oxygen bond energy 3.6 eV):

[0099] Wavelength 355nm: The photon energy of the short-wavelength laser reaches 4.0eV, which is enough to penetrate the surface of the glass and break the silicon-oxygen bond to achieve molecular structure modification;

[0100] Pulse energy 40μJ@15kHz: Single pulse energy is controlled within the glass damage threshold (50μJ) to avoid penetrating the bottle wall while ensuring sufficient energy to destroy the molecular structure;

[0101] Pulse width 1.0ns: Ultra-short pulses enable nanometer-level precision processing, making the edges of the light-absorbing lattice clear and free from thermal diffusion effects;

[0102] 15kHz repetition frequency: balances coding speed (up to 100 pieces / minute) with energy density to avoid excessive material damage.

[0103] 2.2 Absorption region formation process

[0104] After laser pulse focusing, the energy density can reach 106W / cm 2 , stimulating multiphoton absorption within the glass, breaking the silicon-oxygen (Si-O-Si) bonds and forming an amorphous modified region. The modified region's refractive index increases from 1.52 to 1.55, significantly boosting its absorption of 355nm UV light from 5% to 30%. This creates a clear optical contrast with the surrounding unmodified clear glass, resulting in a black dot pattern appearing under specific light sources.

[0105] Example 3: UV detection equipment visualization and channeled goods verification

[0106] 3.1 Testing equipment hardware configuration

[0107] The detection equipment uses a customized UV detection device, and the core components include:

[0108] Light source: 355nm UV LED array, power 60mW, uniformly irradiating the bottle wall at a 45° tilt angle to ensure that the light effectively penetrates and excites the modified area;

[0109] Imaging module: Equipped with a 1280×720 resolution CCD camera and a 355nm bandpass filter (transmittance ≥ 90%, cutoff bandwidth ±5nm) to filter stray light and enhance contrast;

[0110] Software algorithm: Integrated image recognition system, automatically identifies dot patterns and decodes anti-channeling codes. The measured recognition accuracy rate can reach over 99.5%.

[0111] 3.2 Actual testing process

[0112] Place the glass bottle on the inspection station and irradiate the bottle wall with UV light for 50ms.

[0113] Due to the high absorption rate of 355nm light in the modified area (anti-channeling code), it appears as a dark gray dot matrix, forming a character pattern such as "HD002-YZ-202504-0001" with the surrounding transparent area;

[0114] The system automatically reads and analyzes the code. If it detects that a product with the code "HD002" appears in Guangdong (an unauthorized East China region), it is determined to be a channeling violation by distributor B (the general agent in East China).

[0115] Example 4: Anti-destruction capability limit test

[0116] 4.1 Physical destruction experiment

[0117] Polishing test: The outer surface of the bottle was polished continuously for 30 minutes using 200-grit sandpaper, achieving a surface roughness of Ra = 3.2μm, giving the outer surface a frosted appearance. UV testing showed that the anti-channeling code was still clearly readable. Because the code depth of 1.0mm is much greater than the sandpaper wear depth (approximately 0.2mm), the internal modified area was not affected.

[0118] Impact test: A pressure of 5N was applied to the bottle wall (simulating a transport collision). The bottle showed no cracks and the molecular structure of the anti-tampering code area remained stable. When the pressure was increased to 15N, the bottle cracked. At this time, the anti-tampering code area was destroyed, but the bottle's sealing was lost (leakage rate ≥ 50%), making it impossible to sell normally. This proves that the destruction of the anti-tampering code is strongly correlated with the saleability of the product.

[0119] 4.2 Chemical corrosion experiment

[0120] Acid corrosion test: The bottle was immersed in a 10% hydrochloric acid solution for 24 hours. Slight corrosion pits (about 0.1mm deep) appeared on the outer surface. However, the anti-code tampering area 1.0mm inside was not exposed to the solution, so the molecular structure was intact. UV testing showed no significant decrease in code clarity.

[0121] Solvent immersion test: After the bottle was immersed in anhydrous ethanol for 48 hours, no visible changes were found on the glass surface. The anti-tampering code's appearance under UV light remained the same as before immersion, indicating that conventional chemical solvents cannot penetrate the modified area inside the bottle wall and do not affect the integrity of the anti-tampering code.

[0122] Example 5: Large-scale production verification (taking liquor bottles as an example)

[0123] 5.1 Production Line Configuration and Efficiency

[0124] A single production line equipped with a 355nm UV laser coding machine can produce up to 12,000 bottles per hour, with coding time per bottle ≤ 300ms. The equipment consumes 500W, and the energy cost per bottle is calculated to be less than 0.005 yuan. The line also incorporates an automatic focus calibration system, which adjusts the laser head position in real time, keeping the coding position error rate below 0.1%, ensuring stable production at scale.

[0125] 5.2 Cost and Performance Comparison

[0126] Compared with traditional anti-channeling technology, this invention has significant advantages:

[0127] Cost per bottle: Using laser coding technology without consumables, the cost per bottle is approximately 0.012 yuan, which is lower than traditional surface laser codes (0.03 yuan) and fragile label anti-channeling codes (0.05 yuan);

[0128] Difficulty of destruction: The anti-channeling code is located 1.0mm inside the bottle wall. Destruction will cause the bottle to crack or the seal to fail, making the product unsaleable. The difficulty of destruction is much higher than that of surface codes that can be polished off or fragile labels that can be torn off.

[0129] Coding speed: The coding speed reaches 100 pieces / minute, which is higher than the 60 pieces / minute of fragile labels, meeting the needs of high-speed production lines;

[0130] Visibility: Visible only by 355nm ultraviolet light source, it can prevent agents from discovering and destroying it in advance. Compared with traditional codes that are visible to the naked eye, it is more concealed.

[0131] It should be noted that the laser coding machine of the present invention can be replaced by a green light laser machine, and the UV detection device of the 355nm ultraviolet light source can be replaced by a mobile phone lighting lamp. The green light laser machine forms an invisible anti-channeling code that is uniquely bound to the dealer area in the middle of the bottle wall of the glass packaging material. The anti-channeling code is completely located inside the bottle wall and does not touch the surface. The agent cannot remove or tamper with it without destroying the integrity of the bottle (affecting product sales). When the anti-channeling code is printed on transparent glass, it is visible to the naked eye. There is no need to use detection equipment to illuminate the bottle wall to make the anti-channeling code visible. It can be seen directly by the naked eye. The anti-channeling code is uploaded to the anti-channeling management system, and the authorized area is compared with the sales area to determine whether there is channeling. When the anti-channeling code is printed on brown glass or other colored glass, it is not visible to the naked eye. It is necessary to use a mobile phone light to illuminate the bottle wall. The light-absorbing area of the anti-channeling code will contrast with the surrounding glass to become visible. The system reads the code and matches the authorized area to determine whether it is sold across regions. The anti-channeling code is located inside the glass. To destroy it, it is necessary to penetrate the glass layer, causing cracks in the bottle or failure of the seal, making the product unsaleable. Agents have no motivation to destroy it, and tampering with the channeling code is eliminated from physical and economic levels.

[0132] The present invention utilizes the short wavelength characteristics of a 355nm ultraviolet laser (photon energy of 4.0eV, greater than the 3.6eV silicon-oxygen bond energy in glass) to directly break silicon-oxygen bonds through multiphoton absorption, forming a density-differentiated region of [SiO4] tetrahedral structure. This region absorbs 355nm light 50% more than the unmodified region, appearing as a black dot matrix under a UV light source, contrasting with the surrounding transparent glass. Because the modified region is located 0.3-2mm inside the glass and does not damage the integrity of the outer surface, agents cannot remove it through surface treatment. Destroying the internal structure would inevitably impair the physical properties of the bottle, making it unresalable, thus achieving the core purpose of "anti-destruction and anti-channeling."

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.

A method for invisible anti-channelling based on glass materials, comprising an anti-channelling management system, a production coding system, a laser coding machine, glass packaging materials and detection equipment; characterized in that: A laser coding machine is used to form an invisible anti-channeling code in the middle of the bottle wall of the glass packaging material, which is uniquely bound to the dealer area. The anti-channeling code meets the following requirements: Invisible to the naked eye and non-specific light sources, visible only by specific light sources; Located inside the bottle wall and not touching the surface, agents cannot remove or tamper with it without destroying the integrity of the bottle.

2. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The anti-channeling management system includes: The dealer area information management module is used to store each dealer's authorized sales area, dealer code and corresponding anti-channeling code generation rules; The cross-selling tracking module is used to bind the anti-cross-selling code with product logistics information and dealer area information. By scanning the code to identify the authorized area corresponding to the anti-cross-selling code, it can be determined whether there is cross-regional sales behavior.

3. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The production coding system implements anti-code coding through the following steps: a. Obtain the unique anti-channeling code associated with the dealer region from the anti-channeling management system; b. Control the laser coding machine to process the anti-channeling code into the middle of the glass bottle wall, forming an invisible pattern composed of light-absorbing dot matrix.

4. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The laser coding machine focuses a 355nm ultraviolet laser beam on the interior of the glass material and adjusts the pulse parameters to allow the laser energy to form an irreversible molecular structure modification area in the middle of the bottle wall. The modified area has absorption characteristics for light in a specific wavelength band, forming an optical contrast difference with the surrounding material.

5. The invisible anti-channeling method based on glass material according to claim 1 or 4, characterized in that: The coding depth of the laser coding machine is controlled by the pulse duration, and the coding position is 0.3-2 mm away from the glass surface, ensuring that the anti-channeling code is displayed in the middle of the bottle wall and is not exposed to the outer surface.

6. The invisible anti-channeling method based on glass material according to claim 4, characterized in that: The key parameters of the laser marking machine are: Wavelength: 355nm; Pulse energy: >35μJ@15kHz, ensuring that the energy is focused enough to destroy the glass molecular structure but not penetrate the bottle wall; Pulse width: ≤1.1ns, achieving molecular structure modification with nanometer-level precision.

7. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The detection equipment is a UV detection device equipped with a 355nm ultraviolet light source. By irradiating the bottle wall, the light-absorbing area of the anti-channeling code and the unmodified area form a light-dark contrast, thereby revealing the anti-channeling code pattern.

8. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The difficulty of destroying the anti-channeling code is closely related to the integrity of the bottle body: if the anti-channeling code is removed or tampered with, the internal structure of the bottle wall needs to be destroyed, resulting in cracks in the bottle body, abnormal light transmittance and other defects that affect the sealing or appearance of the product, making the product unable to be sold normally.

9. The invisible anti-channeling method based on glass material according to claim 2, characterized in that: The decision logic of the channeling tracking module is: When the authorized area corresponding to the anti-channeling code read by the detection equipment is inconsistent with the actual sales area of the product, it is marked as channeling behavior, and the channeling path and responsible dealer information are recorded.

10. The invisible anti-channeling method based on glass material according to claim 1, characterized in that: The binding relationship between the anti-channeling code and the dealer area is unique in the anti-channeling management system: each anti-channeling code corresponds to and only corresponds to one authorized sales area, and the binding relationship cannot be modified after the production coding.
