Description

Technical Field

[0001] The present invention relates to the field of rock slab processing, and in particular to an anti-counterfeiting coding production line for large-scale ceramic rock slabs and an anti-counterfeiting traceability method thereof. Background Art

[0002] As a new type of decorative material, ceramic rock slabs can be as thick as 3 to 20 mm. The most common specifications are 800×1600 mm. 2 , 900×1800mm 2 、800×2600mm 2 、1200×2400mm 2 、1600×3600mm 2 and other specifications. Compared with ordinary ceramic tiles, ceramic rock slabs have the advantages of large specifications, diverse colors, high temperature resistance, wear resistance, penetration resistance, acid and alkali resistance, and are widely used in the field of home decoration. They can be used for background walls, cabinets, wardrobes, tea sets, bathroom cabinets, washbasins, doors and kitchen stove panels, etc. With the rapid development of the ceramic rock slab construction industry, the output and value of ceramic rock slabs have risen sharply, the products of the ceramic construction industry have become homogenized, and the anti-counterfeiting and traceability of high-end ceramic rock slab products have become issues that brand companies have to consider. The existing anti-counterfeiting and traceability methods in the ceramic construction industry are mainly through local printing of anti-counterfeiting marks such as laser labels, color-printed labels, watermarks, digital codes, etc. at specific positions on the upper surface of the ceramic, or printing a layer of invisible anti-counterfeiting mark layer during the production process of ceramic tiles (such as the fluorescent anti-counterfeiting mark layer disclosed in Chinese patent CN 108623332A).

[0003] However, partially printed anti-counterfeiting labels often occupy a smaller area of ​​the product and are easily erased maliciously, which is particularly unfriendly to large-sized ceramic rock slabs. When the anti-counterfeiting labels are maliciously erased, a large area of ​​the product will still be usable. Once it enters the market, it will be difficult to trace the source of the product and prevent product diversion. Moreover, if the anti-counterfeiting labels are printed on a large area of ​​the ceramic rock slab product, on the one hand, the structure of the ceramic rock slab will be destroyed and the decorative effect of the upper surface will be affected. On the other hand, its production cost is high and the efficiency is low. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, one of the purposes of the present invention is to provide an anti-counterfeiting coding production line for large-scale ceramic rock slabs. This anti-counterfeiting coding production line integrates multiple coding devices for printing and attaching different types of anti-counterfeiting traceability marks, and designs the installation position of the coding devices so that the superimposed use of multiple anti-counterfeiting traceability marks can be basically fully marked on the surface of the ceramic rock slab, thereby improving product recognition and brand image, and effectively solving the problem that the existing anti-counterfeiting traceability marks are small in area and difficult to use on large-scale ceramic rock slabs for anti-counterfeiting and traceability.

After the guide roller turns, it is pressed and covered on the upper surface of the ceramic rock plate by the pressure roller.

[0010] Furthermore, the anti-counterfeiting coding production line for large-size ceramic rock slabs also includes a film cutting machine for cutting the packaging film; the film cutting machine includes a needle tube mechanism for punching holes in the packaging film and a wire knife mechanism for cutting the packaging film.

[0011] Furthermore, the bottom code machine includes a nozzle assembly, a slide rail assembly, and a nozzle transmission assembly; the slide rail assembly includes a slide rail and a slider slidably mounted on the slide rail, the nozzle transmission assembly drives the slider to slide on the slide rail, and the nozzle assembly is mounted on the slider and slides back and forth along the length direction of the slide rail.

[0012] Furthermore, the anti-counterfeiting coding production line for large-scale ceramic rock slabs also includes a curing light source mechanism for accelerating the curing of the W-shaped bottom code. The curing light source mechanism is arranged below the ceramic rock slab on the rock slab conveyor line, and the wavelength of the curing light source is 430-480nm.

[0013] Furthermore, the anti-counterfeiting coding production line for large-scale ceramic rock slabs also includes an isolation cover, which is arranged on the top of the bottom code machine and the curing light source mechanism.

[0014] Furthermore, the laser code machine includes a laser head and a synchronous lifting mechanism. The laser heads located on both sides of the long side of the ceramic rock slab are installed on the synchronous lifting mechanism, and are driven by the synchronous lifting mechanism to adjust the horizontal height position of the laser head according to the thickness of the ceramic rock slab.

[0015] Furthermore, the rock slab conveyor line includes multiple groups of mounting frames, multiple guide wheels are provided on both sides of each group of mounting frames, and multiple parallel roller shafts are provided in the middle of each group of mounting frames.

[0016] The second object of the present invention is achieved by adopting the following technical solution: a method for anti-counterfeiting coding of large-scale ceramic rock slabs, comprising the following steps:

[0017] S1: Conduct quality inspection on the ceramic rock slabs that have completed production and processing, and classify the quality grades of the ceramic rock slabs into superior, first-class, and qualified products; and mark the quality grades of the ceramic rock slabs according to different quality grades;

[0018] S2: The ceramic slabs that have completed quality inspection are transported to the coding workshop through the slab conveyor line, where they are coded;

[0019] S3: The ceramic rock slabs that have completed quality inspection are identified by the code reader to have their quality grade marks, and the different quality grade mark information is sent to the coding control system;

[0020] S4: The coding control system numbers the marking information of different quality grades and matches it with the preset operation instructions of the corresponding quality grades. The coding control system sends corresponding operation instructions based on the different quality grade marking information to control the invisible code machine, labeling machine, bottom code machine, and laser code machine to print the corresponding anti-counterfeiting traceability mark;

[0021] S5: Ceramic rock slabs with superior or first-class quality grades pass through the invisible code machine, film laminating machine, laser code machine, labeling machine, film cutting mechanism, and bottom code machine in sequence, and the corresponding invisible code, laser code, label QR code, and W-shaped bottom code are respectively printed and attached on the upper surface, long side and lower surface of the ceramic rock slab; Ceramic rock slabs with qualified quality grades pass through the film laminating machine, labeling machine, and W-shaped bottom code machine in sequence, and the corresponding label code and bottom code are respectively attached and printed on the upper surface and lower surface of the ceramic rock slab;

[0022] S6: The ceramic rock slabs that have been coded are transported by the rock slab conveyor line and heated by the curing light source mechanism to cure each anti-counterfeiting traceability mark;

[0023] S7: The dried ceramic rock slabs are identified by a code reader to identify their quality grade marks, and the packaging robot classifies, cuts, stacks and packages the ceramic rock slabs according to different quality grades.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) This anti-counterfeiting coding production line integrates a variety of coding devices for printing and attaching different types of anti-counterfeiting traceability marks, and designs the installation position of the coding devices so that the superposition of multiple anti-counterfeiting traceability marks can be basically marked on the surface of the ceramic rock plate in all directions, thereby improving product recognition and brand image, and effectively solving the problem that the existing anti-counterfeiting traceability marks have a small area and are difficult to use on large-sized ceramic rock plates for anti-counterfeiting traceability.

[0026] Specifically, this application uses four anti-counterfeiting traceability marks, namely, invisible code, label QR code, laser code, and W-shaped bottom code, which are spray-printed and attached to the same ceramic rock plate. The above four codes all contain the unique number of the ceramic rock plate product, and multiple anti-counterfeiting traceability marks are used for multiple anti-counterfeiting traceability. In addition, four anti-counterfeiting traceability marks are superimposed and spray-printed and attached to the upper and lower surfaces and sides of the ceramic rock plate. Since the four anti-counterfeiting traceability marks occupy a large area of ​​the ceramic rock plate as a whole and have a wide distribution space, it is difficult for all of them to be maliciously erased. Even if all of the four anti-counterfeiting traceability marks are maliciously erased, the overall remaining area of ​​the ceramic rock plate is small, resulting in the ceramic rock plate being unable to be sold or used normally; and if only part of the anti-counterfeiting traceability marks are maliciously erased, the product can still be traced through the numbering information contained in the remaining anti-counterfeiting traceability marks, thereby improving product recognition, improving brand image, reducing business risks, and improving corporate visibility and reputation.

[0027] (2) In addition, this anti-counterfeiting coding production line is also equipped with a label recognition machine and a general coding control system. The label recognition machine obtains and identifies the quality grade mark of the ceramic rock slab, and then the general coding control system controls the invisible code machine, labeling machine, bottom code machine, and laser code machine to print the corresponding anti-counterfeiting traceability mark according to the quality grade mark information of the ceramic rock slab provided by the label recognition machine, so that this equipment can automatically realize the anti-counterfeiting coding processing of ceramic rock slab products of different quality grades, with high printing efficiency, high anti-counterfeiting effect, and high degree of equipment automation.

[0028] (3) This anti-counterfeiting coding method designs multiple anti-counterfeiting traceability marks to avoid problems such as a single anti-counterfeiting traceability mark being easily damaged, fallen off, artificially replaced, forged, reused, or maliciously erased, thereby truly ensuring the possibility and effectiveness of product traceability and increasing consumers' confidence in product quality.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] like Figure 1-8 As shown, the present invention provides an anti-counterfeiting coding production line for large-scale ceramic rock slabs, including a rock slab conveyor line 1 for conveying ceramic rock slabs A that have completed quality inspection, an invisible code machine 2 for printing invisible codes on the upper surface of the ceramic rock slab A, a film laminating machine 3 for laminating packaging film on the upper surface of the ceramic rock slab A that has been printed with invisible codes, a labeling machine 4 for attaching a label QR code to the packaging film on the surface of the ceramic rock slab, a bottom code machine 5 for printing a W-shaped bottom code on the lower surface of the ceramic rock slab A, and a laser code machine 6 for printing a laser code on both sides of the ceramic rock slab A; the invisible code machine 2, film laminating machine 3, and labeling machine 4 are arranged above the ceramic rock slab A on the rock slab conveyor line 1, the bottom code machine 5 is arranged below the ceramic rock slab A on the rock slab conveyor line 1, and the laser code machine 6 is arranged on both sides of the conveying direction of the rock slab conveyor line 1.

[0040] This application mainly uses four anti-counterfeiting traceability marks: invisible code B1, laser code B2, label QR code B3, and W-type bottom code B4, which are printed and attached to the same ceramic rock plate A. Figure 8 As shown, the above four codes all contain the unique serial number of the ceramic rock slab product, and multiple anti-counterfeiting traceability marks are used for multiple anti-counterfeiting traceability. In addition, the four anti-counterfeiting traceability marks are superimposed and printed and attached to the upper, lower and side surfaces of the ceramic rock slab. Since the four anti-counterfeiting traceability marks occupy a large area of ​​the ceramic rock slab as a whole and are distributed in a wide space, it is difficult to maliciously erase all of them. Even if all four anti-counterfeiting traceability marks are maliciously erased, the overall remaining area of ​​the ceramic rock slab is small, resulting in the ceramic rock slab being unable to be sold or used normally; and if only part of the anti-counterfeiting traceability marks are maliciously erased, the product can still be traced through the number information contained in the remaining anti-counterfeiting traceability marks, thereby improving product recognition, enhancing brand image, reducing business risks, and improving corporate visibility and reputation, effectively solving the problem that the existing anti-counterfeiting traceability marks have a small area and are difficult to use for anti-counterfeiting traceability on large-scale ceramic rock slabs.

[0041] In this solution, the invisible code printed by the invisible code machine uses blue light invisible ink, which can be revealed by irradiating the invisible code with blue light. The label QR code allows users to scan the QR code on the label to obtain the product's origin. The ink printed by the base code machine is mainly composed of photosensitive resin ink.

[0042] In addition, the larger the specifications of the ceramic rock slab, the better the anti-counterfeiting and traceability effect of the present application. Preferably, the specifications of the ceramic rock slab A are greater than: width 1200mm × length 2400mm × thickness 3mm.

[0043] In this embodiment, the invisible code information located on the upper surface of the ceramic rock plate A includes but is not limited to product information such as product number, color number, brand, production date, and production time. Specifically, the number of invisible codes set is designed according to the length of the long side of the ceramic rock plate. The longer the long side of the ceramic rock plate, the more invisible codes there are. Preferably, the invisible code is located in the center of the short side of the ceramic rock plate, and multiple invisible codes are arranged in a line in sequence, parallel to the long side direction of the ceramic rock plate.

[0044] The QR code information on the surface packaging film of the ceramic rock plate A includes, but is not limited to, product information such as product number, color number, brand, production date, and production time. Specifically, the QR code on the label is randomly distributed on the surface packaging film of the ceramic rock plate and does not overlap with the invisible code.

[0045] The laser code information located on the long side of ceramic rock slab A includes but is not limited to product information such as product number, color number, brand, production date, and production time.

[0046] The W-shaped bottom code located on the lower surface of ceramic slab A is shaped like the letter "W", but is not limited to this letter shape. It can also be shaped like the letter "M", "m", "U" or a wave. The entire "W" shape basically or completely covers the entire bottom surface of the ceramic slab to increase the area occupied by the anti-counterfeiting traceability mark on the ceramic slab and increase the difficulty of malicious erasure. The W-shaped bottom code includes but is not limited to product information such as product number, brand, Chinese trademark, English trademark, numbers, letters, etc.

[0047] As a further preferred solution, the anti-counterfeiting coding production line for large-size ceramic rock slabs also includes a marking machine 7 for obtaining and identifying the quality grade marks of the ceramic rock slabs and a coding general control system 8 for controlling the invisible code machine 2, labeling machine 4, bottom code machine 5, and laser code machine 6 to print corresponding anti-counterfeiting traceability marks according to the quality grade mark information of the ceramic rock slabs provided by the marking machine; the coding general control system 8 is electrically connected to the marking machine 7, invisible code machine 2, labeling machine 4, bottom code machine 5, and laser code machine 6.

[0048] This anti-counterfeiting coding production line is also designed with a label recognition machine 7 and a coding control system 8. The label recognition machine 7 obtains and identifies the quality grade mark of the ceramic rock slab, and then the coding control system 8 controls the invisible code machine 2, labeling machine 4, bottom code machine 5, and laser code machine 6 to print the corresponding anti-counterfeiting traceability mark according to the ceramic rock slab quality grade mark information provided by the label recognition machine 7, so that this equipment automatically realizes the anti-counterfeiting coding processing of ceramic rock slab products of different quality grades, with high printing efficiency, high anti-counterfeiting effect, and high degree of equipment automation.

[0049] In addition, each coding station of the invisible code machine 2, labeling machine 4, bottom code machine 5, and laser code machine 6 is equipped with a code reader for collecting the working status of each station, and the code reader is electrically connected to the coding control system. The working status of each station includes but is not limited to real-time data and fault data of printing. The code reader of each coding station will upload the collected working status of each station to the cloud of the coding control system 8 in real time. If a coding station makes an error or reports a fault during the coding process, the coding control system 8 will push the relevant data to the terminal device, such as a mobile phone, so that the technician can know the production data of the production line in the first time. It can be seen that this production line equipment not only has the anti-counterfeiting and traceability function of ceramic rock slabs at the supplier and consumer ends, but also has the traceability feedback function during the production process.

[0050] As a further preferred solution, Figure 3 As shown, the laminating machine 3 includes a pressure roller 31, a pressure roller driving device (not shown in the figure), a film strip feeding roller 32, and a guide roller 33; the pressure roller 31 is set on the upper surface of the ceramic rock plate A, and is driven by the pressure roller driving device to rotate and move closer to or away from the ceramic rock plate A. The film strip feeding roller 32 is wrapped with a packaging film, and the packaging film on the film strip feeding roller 32 is wound on the guide roller 33. After the guide roller 33 turns, it is pressed and covered on the upper surface of the ceramic rock plate by the pressure roller 31. The design of the laminating machine 3 is to cover the ceramic rock plate A with a packaging film to prevent the surface texture of the ceramic rock plate from being scratched and improve the product quality. At the same time, the use of a label QR code on the surface of the packaging film makes it convenient for consumers to scan the QR code on the label at the consumer terminal to know the source of the product.

[0051] As a further preferred solution, the anti-counterfeiting coding production line of the large-scale ceramic rock slabs also includes a film cutting machine 9 for cutting the packaging film; the film cutting machine 9 includes a needle tube mechanism 91 for punching holes in the packaging film and a wire knife mechanism 92 for cutting the packaging film. After the wrapping paper is wrapped on the upper surface of the ceramic rock slab by the film laminating machine 3, the packaging film needs to be cut. In this cutting step, there are two sub-steps, namely pre-cutting and formal cutting. The packaging film is pre-cut by punching holes in the packaging film by the needle tube mechanism 91 to reduce the surface tension of the packaging film material and avoid wire drawing during the later cutting; and then the formal cutting is carried out by the wire knife mechanism 92. Specifically, as Figure 3-4 As shown, the needle tube mechanism 91 includes a tube body 911 arranged horizontally on the upper surface of the ceramic rock plate A and a puncture needle 912 fixed on the surface of the tube body. The length direction of the tube body is parallel to the short side direction of the ceramic rock plate A located on the rock plate conveyor line 1. Figure 5 As shown, the wire cutter mechanism 92 includes a steel wire 921 arranged horizontally on the upper surface of the ceramic rock plate A, a fixed rocker 922 for fixing the steel wire, and a cylinder drive assembly (not shown in the figure) for driving the fixed rocker to swing along the axis of the rocker.

[0052] As a further preferred solution, Figure 6-7 As shown, the bottom code machine 5 includes a printhead assembly 51, a slide rail assembly 52, and a printhead transmission assembly 53. The slide rail assembly 52 includes a slide rail 521 and a slider 522 slidably mounted on the slide rail. The printhead transmission assembly 53 drives the slider to slide on the slide rail 521. The printhead assembly 51 is mounted on the slider 522 and slides back and forth along the length of the slide rail 521. Preferably, the printhead transmission assembly 53 is a pulley assembly, specifically including a belt 531, pulleys 532, and a motor 533. The belt 531 is mounted on two pulleys 532. The slider 522 is fixed to the belt 531. The motor 533 drives the pulleys 532 to rotate, thereby driving the printhead assembly 31 fixed to the belt 531 to slide back and forth along the length of the slide rail 521. In this embodiment, the printhead assembly 51 consists of two printheads. The spacing between the two printheads and the reciprocating speed of the printheads can be adjusted to accommodate printing of different product sizes, thus expanding its applicability. In addition, the bottom coding machine 5 can spray codes on a single ceramic rock slab without stopping the rock slab conveyor line 1, effectively improving work efficiency.

[0053] As a further preferred solution, Figure 6 As shown, the anti-counterfeiting coding production line of the large-scale ceramic rock slab A also includes a curing light source mechanism 10 for accelerating the curing of the W-type bottom code. The light source used by the curing light source mechanism can be an ultraviolet light source with a wavelength of 430 to 480 nm. The curing light source mechanism 10 is arranged below the ceramic rock slab A on the rock slab conveyor line 1. Immediately after the printing of the W-type bottom code is completed, the curing light source mechanism is used to accelerate the curing of the ink. Preferably, ultraviolet lamp lines are used for light curing. Compared with direct heating of the heating wire, the ultraviolet lamp curing method can prevent the packaging film from detaching, and the ink of the W code can be light-cured within a few seconds, effectively protecting the integrity of the four-in-one code.

[0054] As a further preferred embodiment, the anti-counterfeiting coding production line for large-sized ceramic slabs A further comprises an isolation cover 11, which is arranged on top of the bottom code machine 5 and the curing light source mechanism 10. The design of the isolation cover not only prevents external light from irradiating the photosensitive resin, thereby affecting the curing efficiency, but also protects the workers from damage caused by ultraviolet radiation.

[0055] As a further preferred embodiment, the laser code reader 6 includes a laser head 61 and a synchronous lifting mechanism (not shown). The synchronous lifting mechanism in this example can be a conventional lifting device capable of achieving height movement. The laser heads 61 located on both sides of the long side of the ceramic rock slab A are mounted on the synchronous lifting mechanism, and the synchronous lifting mechanism drives the laser heads 61 to adjust their horizontal height position according to the thickness of the ceramic rock slab A.

[0056] As a further preferred embodiment, the rock slab conveyor line 1 includes multiple groups of mounting frames 101 , multiple guide wheels 102 are provided on both sides of each group of mounting frames 101 , and multiple parallel roller shafts 103 are provided in the middle of each group of mounting frames 101 .

[0057] The present invention also provides an anti-counterfeiting coding method for large-scale ceramic rock slabs, which uses the anti-counterfeiting coding production line as described above to perform coding, and specifically includes the following steps:

[0061] S4: The coding control system 8 numbers the different quality grade marking information and matches it with the preset operation instructions of the corresponding quality grade. The coding control system 8 sends corresponding operation instructions according to the different quality grade marking information to control the invisible code machine 2, labeling machine, bottom code machine 5, and laser code machine 6 to print the corresponding anti-counterfeiting traceability mark;

[0062] S5: Ceramic rock slabs A with a quality grade of superior or first-class pass through the invisible code machine 2, film laminating machine 3, laser code machine 6, labeling machine 4, film cutting machine 9, and bottom code machine 5 in sequence, and are respectively printed and attached with corresponding invisible codes B1, laser codes B2, label QR codes B3, and W-shaped bottom codes B4 on the upper surface, long side, and lower surface of the ceramic rock slab A; Ceramic rock slabs with a quality grade of qualified pass through the film laminating machine 3, labeling machine 4, and bottom code machine 5 in sequence, and are respectively attached and printed with corresponding label codes and bottom codes on the upper surface and lower surface of the ceramic rock slab A;

[0063] S6: The ceramic slab A that has completed the coding process is transported by the slab conveyor line 1 and solidified with various anti-counterfeiting traceability marks by a curing light source mechanism;

[0064] S7: The dried ceramic rock slabs A are identified by a code recognition machine for their quality grade marks, and the packaging robot classifies, cuts, stacks and packages the ceramic rock slabs A according to different quality grades.

[0065] This anti-counterfeiting coding method designs multiple anti-counterfeiting traceability marks to avoid problems such as single anti-counterfeiting traceability marks being easily damaged, falling off, manually replaced, forged, reused or maliciously erased, and effectively improves the link and data credibility of ceramic rock slab product life cycle data, thereby truly ensuring the possibility and effectiveness of product traceability and increasing consumers' confidence in product quality.
