Description
Technical Field
The embodiment of the invention relates to the technical field of traceability and anti-fleeing, in particular to a production method and a system of a traceability and anti-fleeing code of a canned product.
Background
A fleeing good is a business that ultimately aims to be profitable. The conscious sales of the dealers across the self-covered sales area and in other areas is the goods-fleeing behavior, also called as the goods-rushing, and is a vicious marketing phenomenon that the dealers sell the distributed products across areas under the drive of benefits of company branches or intermediaries in a dealer network, so that market rolling and price confusion are caused, and the reputation of the dealers is seriously influenced. At present, a method for preventing channel conflict mainly adds a carrier carrying product tracing information, such as a one-dimensional code, a two-dimensional code and the like, on product packaging.
For domestic canned products, the production mode of the commonly used tracing and channeling-preventing means is as follows: when the can body packaging material is in a flat state, tracing anti-channeling codes such as two-dimensional codes and the like are jet-printed on the surface of the material in a printing stage. However, this method can only be applied to canned products made of metal, and is not suitable for canned products made of plastic by injection molding. However, after the code is sprayed on the flat metal material, operations such as tank body rolling, complementary coating and the like are still required, and the recognition effect of the traceable anti-channeling code such as the two-dimensional code can be influenced to a certain extent. The production mode is as follows: the label containing the tracing anti-fleeing code such as the two-dimensional code is manufactured in a printing factory, and then the label is attached to the can body of the canned product in the production stage of the product. Although the method can be applied to canned products made of all materials, the label is easy to tear and replace and has low safety. Furthermore, neither method is applicable to canned products that have already been made into finished products, such as imported products.

Example one
Fig. 1 is a schematic flow chart of a method for producing a traceability anti-tamper code for a canned product according to an embodiment of the present invention, which is applicable to the production of traceability anti-tamper codes for finished canned products. As shown in fig. 1, a method for producing a traceability tamper-proof code for a canned product according to an embodiment of the present invention includes:
and S110, acquiring two-dimensional code image information of finished canned products.
Specifically, the finished canned product refers to a canned product ready for use or sale. The two-dimensional Code is also called a two-dimensional bar Code (2-dimensional bar Code), and the most common form is a QR Code (Quick Response Code), and the two-dimensional Code is distributed on a plane (in a two-dimensional direction) at intervals of black and white according to a certain rule through a certain specific geometric figure, so as to record data symbol information. The two-dimensional code has the characteristics of large storage capacity, high confidentiality, high traceability and the like, and at present, a plurality of manufacturers paste two-dimensional code labels on commodities and use the two-dimensional code for preventing and tracing.
Further, the barcode images used for tracing and preventing the source of the commodity are collectively called as a source-tracing and code-fleeing preventing image, such as a two-dimensional code image, a microscopic graphic unit image, and the like. The content contained in the traceable anti-channeling code image is called traceable anti-channeling code image information and generally comprises a product query link and a code value, wherein the product query link is a link used for querying product information displayed by the traceable anti-channeling code image, the code value is equivalent to an identity of the traceable anti-channeling code image, and different traceable anti-channeling code images have different code values. The two-dimensional code image information is content contained in the two-dimensional code image, and comprises a first product inquiry link of the two-dimensional code image and a first code value of the two-dimensional code image, and the two-dimensional code image information is acquired, namely the first product inquiry link and the first code value of the two-dimensional code image are acquired.
In this embodiment, the two-dimensional code image information may be acquired by scanning the two-dimensional code image with a dedicated two-dimensional code acquisition camera. The two-dimensional code image can be a two-dimensional code image on a two-dimensional code label pasted on a finished canned product by a supplier of the finished canned product, or a two-dimensional code image generated after a merchant carries out secondary processing on the original finished canned product without the two-dimensional code image. For example, a supplier of domestic finished canned products usually attaches a two-dimensional code label to the finished canned products, and finished canned products imported from abroad may not generally attach a two-dimensional code label, and then secondary processing is required to be performed on the imported finished canned products, and a two-dimensional code label is attached to the surface of the finished canned products, so that two-dimensional code image information can be acquired.
And S120, generating a microscopic graphic unit image according to the two-dimensional code image information.
Specifically, the microscopic graphic unit image is a microscopic coding image with a code point diameter of about 30-60 microns, the microscopic graphic unit image can record a large amount of data and is extremely difficult to copy, a plurality of identifiable units can be arranged in a certain area, and even if the microscopic graphic unit image is damaged in a large area, the information can still be effectively read, so that a good anti-counterfeiting and anti-channeling effect can be achieved, and the microscopic graphic unit image has a great advantage in tracing and anti-channeling application.
Further, the micro graphic element image also has micro graphic element image information including a second product inquiry link for the micro graphic element image and a second code value for the micro graphic element image.
The method comprises the steps of generating a microscopic graphic unit image according to two-dimensional code image information, namely generating a second code value according to a first code value of the two-dimensional code image, generating a second product inquiry link according to a first product inquiry link of the two-dimensional code image, and then generating the microscopic graphic unit image comprising the second code value and the second product inquiry link by adopting a special microscopic graphic unit image generation algorithm according to the second code value and the second product inquiry link.
Furthermore, according to the generation process of the micro graphic unit image, the first product inquiry link is consistent with the second product inquiry link, and the first code value is consistent with the second code value. The coincidence of the first code value and the second code value means that the first code value and the second code value are coincident or the first code value and the second code value are matched. For a two-dimensional code image, the first code value may include both numbers and letters, and for a microscopic graphic element image, the second code value is purely digital, so that when only numbers are contained in the first code value, the correspondingly generated second code value may be consistent with the first code value; when the first code value contains letters, the letters in the first code value need to be converted according to a conversion rule (for example, the letters are converted into numbers, or the letters are deleted), and then a corresponding second code value without letters is generated, so that the first code value and the second code value are matched.
S130, performing a first coding operation on the microscopic graphic unit image to endow the microscopic graphic unit image with the product source tracing information of the finished canned product.
Generally, product tagging refers to a process of tagging products or product packages with carriers capable of carrying information and serving as unique product identifiers, and writing basic information, traceability information and the like of the products into the carriers, and the product tagging is an important link in product traceability and anti-fleeing application. In this embodiment, the code assigning operation refers to a process of writing product basic information, traceability information, and the like into a carrier serving as a unique product identifier, and the first code assigning operation is to write product traceability information of a finished canned product into a microscopic graphic unit image. The product traceability information refers to relevant information of finished canned products with traceability and anti-channeling functions, and includes but is not limited to basic information of the products (such as product names, instructions, ingredients, specifications, validity periods, production enterprises and the like), production information (such as production factories, production lines, production teams, production dates, product batches and the like), logistics distribution information and the like.
Generally, the product tracing information is stored in a certain address in the server, and the product tracing information of the finished canned product is given to the micro graphic unit image, that is, the product tracing information of the finished canned product is written into the micro graphic unit image, that is, the storage address of the product tracing information in the server is associated with the second product query link of the micro graphic unit image.
And S140, spraying and printing the coded microscopic graphic unit image at a first preset position of the finished canned product through an invisible ink code spraying process.
Specifically, the invisible ink code spraying process is a spray printing operation using invisible spray printing ink, for example, infrared invisible ink with a specific wavelength can be used for the code spraying operation, and the invisible ink code spraying process enables the microscopic graphic unit image to have good adhesiveness and strong concealment. The first preset position is a preset position for spray printing the micro graphic unit image, for example, the first preset position is a position of a can body side wall of a finished canned product. The device for carrying out the spray printing operation is called a code spraying device, and the first preset position can be adjusted by adjusting the direction of the finished canned products on the production line facing the code spraying device. Optionally, a code spraying device with code spraying resolution not lower than 300 × 300DPI (Dots Per Inch) is adopted to perform code spraying operation, preferably, the code spraying device is a code spraying device with code spraying resolution of 600 × 600DPI or more, and the size of the microscopic graphic unit image is 15 × 15mm or more, so that even if the microscopic graphic unit image is damaged in a large area, 10% of the area (about 3 × 3mm) can effectively read information.
The microcosmic graphic unit image after code endowing is sprayed and printed at the first preset position of the finished canned product through the invisible ink code spraying process, so that the microcosmic graphic unit image after being sprayed and printed is invisible to human eyes, the attractiveness of the pattern on the original finished canned product is not influenced, the microcosmic graphic unit image has concealment performance, is not easily damaged manually, and the effect of tracing and preventing channeling is enhanced.
The production method of the canned product traceability anti-fleeing code provided by the embodiment of the invention enables the canned product traceability anti-fleeing code to comprise the two-dimensional code (the plain code) and the microscopic graphic unit image (the hidden code) which is jet-printed by using the invisible ink jet printing process, and through the combination of the plain code and the hidden code, the traceability anti-fleeing effect of the canned product is further enhanced, and the safety of the canned product is improved. In addition, the traceability anti-fleeing code production method for canned products provided by the embodiment of the invention can directly perform traceability anti-fleeing processing on finished canned products which are processed, greatly expands the application of traceability anti-fleeing technology on imported finished canned products, and improves the efficiency and accuracy of finished canned product fleeing inspection.
Example two
Fig. 2A is a schematic flow chart of a method for producing a traceability anti-tampering code of a canned product according to a second embodiment of the present invention, which is a further refinement of the above embodiment. As shown in fig. 2A, the production method of the traceability anti-tamper code for canned products provided by the second embodiment of the present invention includes:
and S210, pasting a two-dimensional code label at a second preset position of the finished canned product.
Specifically, the two-dimensional code label is a printed matter including a two-dimensional code for identifying relevant specifications of canned products, and a printing factory specially producing the two-dimensional code label is provided, so that the two-dimensional code label can be produced in advance by the printing factory and then is pasted on finished canned products. The second preset position is a position on the finished canned product for adhering the two-dimensional code label, and the two-dimensional code label is visible to the human eye, so that the tank body pattern and the attractiveness of the original finished canned product are not affected, the second preset position can be a position hidden on the finished canned product or a position which does not affect the tank body pattern of the original finished canned product, for example, the second preset position is the tank bottom position of the finished canned product.
Further, pasting the two-dimensional code label can be accomplished through automatic labeling machine, place finished product canned product tank bottoms up on the production line of automatic circulation, when finished product canned product flows through automatic labeling machine, automatic labeling machine just can follow the top and paste the two-dimensional code label in the bottom of finished product canned product. Optionally, in order to better acquire two-dimensional code image information subsequently, the size of the two-dimensional code image on the two-dimensional code label is 15 × 15mm, and is preferably not less than 10 × 10 mm.
In an alternative embodiment, the two-dimension code label is pasted at the second preset position of the finished canned product, and the two-dimension code label can be replaced by: and engraving the two-dimensional code image at a second preset position of the finished canned product. The laser engraving machine can directly engrave the two-dimensional code image on the finished canned product without sticking a label, so that paper is saved, and the laser engraving machine is more environment-friendly.
And S220, collecting two-dimensional code image information on the two-dimensional code label.
And S230, if the collection is successful, performing second code assigning operation on the two-dimension code image on the two-dimension code label so as to assign the product source tracing information of the finished canned product to the two-dimension code image.
Specifically, acquiring the two-dimensional code image information refers to identifying a first product inquiry link and a first code value of the two-dimensional code image through a special two-dimensional code acquisition camera. The acquisition of the two-dimensional code image information needs a special acquisition device, such as a two-dimensional code acquisition camera. When the two-dimensional code acquisition camera can acquire the first product inquiry link and the first code value of the two-dimensional code image, the acquisition is successful, otherwise, the acquisition fails, and the two-dimensional code image may be damaged or the two-dimensional code label is not pasted in place.
For the two-dimension code image before the acquisition is successful, the first product inquiry link of the two-dimension code image is not associated with any product information, namely the two-dimension code is null, no real-time content is stored, so that the two-dimension code image information needs to be acquired, the second code assigning operation is carried out on the two-dimension code image, the product traceability information of the finished canned product is assigned to the two-dimension code image, namely the first product inquiry link of the two-dimension code image is associated with the storage address of the product traceability information in the server. The product traceability information of the finished canned product can be obtained only by the code assigning operation and scanning the two-dimensional code image.
S240, if the collection fails, entering a first exception handling process.
Specifically, the acquisition failure means that any one of the first product inquiry link and the first code value of the two-dimensional code image cannot be acquired by the two-dimensional code acquisition camera, and the reason for causing such a situation may be that the two-dimensional code image is damaged or the two-dimensional code label is not adhered in place, and if the two-dimensional code label of the automatic labeling machine is not replaced in time after being used up, the finished canned product cannot be acquired naturally because the two-dimensional code label is not adhered to the finished product canned product on the production line although flowing through the automatic labeling machine. If the two-dimensional code image information acquisition fails, finished canned products which fail in the two-dimensional code image information acquisition can be placed into a first exception handling area through an eliminating device, and a first exception handling process is entered, so that the two-dimensional code image information can be successfully acquired.
Further, as shown in fig. 2B, the first exception handling flow includes steps S241 to S243.
And S241, the two-dimension code image information on the two-dimension code label is collected again through the two-dimension code handheld scanning gun.
Specifically, for finished canned products with failed two-dimensional code image information acquisition, the staff can determine whether two-dimensional code labels are adhered to the finished canned products through visual inspection, and if the finished canned products are not adhered with the two-dimensional code labels, the finished canned products can be placed back to the production line again, so that the step S210 is performed again to adhere the labels. If finished canned products are pasted with the two-dimension code label, the staff can scan the two-dimension code image on the two-dimension code label through the handheld scanning gun of two-dimension code, and the two-dimension code image information is gathered again.
