[0052] like Figure 1 As shown, a method for making a high-temperature invisible two-dimensional code label for glass processing includes the following steps:
[0053] Step S1: preparing raw materials, preparing glass products to be processed, and cleaning them;
[0054] Step S2: prepare inkjet materials and load the high-temperature invisible ceramic coating into the inkjet equipment;
[0055] Step S3: Equipment debugging, inputting the QR code label design draft to be sprayed into the coding equipment, and performing a spraying test until the sprayed QR code label is clearly identifiable;
[0056] Step S4: spraying a QR code label, using a coding device to spray a high-temperature invisible ceramic coating onto the glass product to be processed to form a QR code label spray surface;
[0057] Step S5: Initial verification, using a display light source to illuminate the QR code area, and scanning and verifying through scanning software, and recording the initial reading success rate;
[0058] Step S6: Tempering treatment, sending the glass product to be processed after coding into a tempering furnace for tempering treatment;
[0059] Step S7: Verify again, scan and verify the QR code area by displaying the light source and scanning software, and record the re-reading success rate;
[0060] Step S8: According to the initial reading success rate and the re-reading success rate, adjust the parameters of the inkjet printer and repeat steps S3 to S7.
[0061] Material and equipment selection:
[0062] (1) Glass products to be processed: Standard architectural-grade float glass with a size of 50 cm x 50 cm and a thickness of 5 mm.
[0063] (2) High-temperature resistant invisible ceramic coating: It uses commercially available high-temperature ceramic ink, model "CeramicMark QR". This coating has a temperature resistance of up to 1200°C and has good chemical stability and adhesion.
[0064] (3) Coding equipment: Use industrial-grade UV inkjet printer, model "UVJetPro2000", equipped with precision nozzle to ensure the fineness of the QR code pattern.
[0065] (4) Reading device: A smartphone equipped with the professional QR code scanning software "QRCode Pro" and a portable UV light source "UVLite X3".
[0066] Steps S1 to S4 are the preparation stage, and it is necessary to ensure that the glass surface is free of dust, oil stains and other impurities and wipe it clean with alcohol.
[0067] Correctly load the "CeramicMark QR" paint into the ink cartridge of the "UVJetPro2000" inkjet printer.
[0068] Design and debug the QR code in dedicated software to ensure it is legible within the intended area, while adjusting the printer parameters to suit the coating characteristics.
[0069] In a dust-free environment, use an inkjet printer to evenly spray the QR code onto the glass surface to form an invisible layer.
[0070] Initial verification: After spraying, immediately use "UVLite X3" to illuminate the QR code area, and use the mobile phone camera with "QRCode Pro" software to scan and verify for the first time. The initial reading success rate was recorded to be 98%, indicating that the QR code is clear and can be accurately identified.
[0071] Step 6 and Step 7 (tempering and secondary verification):
[0072] The glass sheet with the invisible QR code is sent into the tempering furnace, heated to 680°C according to the standard process, and then quickly cooled.
[0073] The tempered glass was scanned again using the UVLite X3 and a mobile phone scanning software. At this stage, the reading accuracy remained above 95%, proving that the QR code remained highly readable after high temperature treatment.
[0074] Test results analysis
[0075] High temperature resistance test: After the actual tempering process, the QR code did not fall off, become blurred or unrecognizable, verifying its excellent high temperature tolerance.
[0076] Reading accuracy test: The reading accuracy of the initial test and after tempering is higher than the industry standard (usually required to be ≥90%), demonstrating the high reliability and practicality of the technology.
[0077] Chemical Stability and Weathering Resistance: Although this case was not directly tested for long-term chemical corrosion or outdoor exposure, based on the technical specifications of the "CeramicMark QR" coating, it is expected to have good durability in normal environments.
[0078] After the glass is cut, the present invention immediately sprays the invisible two-dimensional code label, and sends the glass with the invisible two-dimensional code label into a tempering furnace for tempering treatment. Since high-temperature resistant ceramic coating is used, the problem of paper label burning is solved.
[0079] High safety and efficiency:
[0080] Avoiding label tearing and sticking during the operation process reduces human errors and improves the continuity and stability of the production process. It is expected to reduce downtime and maintenance costs caused by label problems and improve overall production efficiency by about 15%-25%.
[0081] (2) Improved aesthetics:
[0082] The invisible QR code will not affect the overall appearance of the glass, which meets the sensory needs of users. This not only improves the market competitiveness of the product, but also reduces customer complaints and return rates caused by appearance problems, indirectly improving sales efficiency and customer satisfaction.
[0083] (3) High temperature adaptability:
[0084] No need to worry about the impact of high temperature process on the label, ensuring long-term identification effectiveness. This is especially important for the high temperature processing environment of the glass industry, avoiding the problem of traditional paper labels being damaged at high temperatures, thereby reducing delays and increased costs caused by label problems during the production process. It is expected to reduce production delays by at least 5%
[0085] During inspection, warehousing or shipping, a special light source (such as UV light or infrared light) is used to illuminate the glass surface to identify the QR code label.
[0086] It uses high temperature resistant ceramic paint, which can withstand temperatures up to 1200 degrees.
[0087] -Combining the light wave absorption characteristics of different materials to create invisible QR code labels.
[0088] Chemical stability: It remains stable in acidic and alkaline environments and is not prone to chemical reactions, ensuring the readability and integrity of the QR code during long-term use.
[0089] Adhesion: Forms a strong bond with the glass surface, and is not easy to fall off or wear even under extreme conditions, ensuring the durability of the logo.
[0090] Weather resistance: It can resist the erosion of ultraviolet rays and other environmental factors, and is suitable for various indoor and outdoor environmental conditions to extend the service life.
