For example, the Chinese patent document CN102069061A is referred to as the second document, a method for preparing a micro-point anti-counterfeit coating disclosed on May 25, 2011, a device for carrying out the method, and a package containing the anti-counterfeit coating prepared by the method. body. The preparation method of the micro-point anti-counterfeit coating comprises the following steps: S1, providing micro-dots and providing UV glue; S2, mixing; S3, micro-spraying; S4, curing. The preparation device of the micro-point anti-counterfeit coating comprises a glue storage device, a micro-injection device, a curing device, the glue storage device is connected with the micro-injection device, and the micro-injection device is provided with glue to be sprayed, and the curing device is disposed at the rear end of the micro-injection device, The micro-spraying device further comprises a dosing chamber and a nozzle communicating with the dosing chamber, wherein the dosing chamber is provided with a pressurizing piston; the jetting hole of the nozzle has a diameter of between 1.25 micrometers and 630 micrometers; A driving device for moving the nozzle, the driving device provides the nozzle with two horizontal movements and a vertical movement.

For example, the Chinese patent document CN202711592U is hereinafter referred to as the third document, a logo, a label preparation device and an assembly line disclosed on January 30, 2013.

Although the aforementioned patented technology can be applied in the industry and achieve the corresponding technical effects, there are still changes. Good space.

The technique disclosed in the first document only discloses the glue mixed with micro-dots on the carrier, and does not show how to realize high-speed automatic dispensing, which is not suitable for high-speed automatic assembly line operation; further, the document does not The shape of the microdots and the number of microdots in each droplet are limited. For the symmetric all micropoints, when the number of microdots in the droplet is less than 5, the position of the microdots and the shape of the self are random. Formed, the visual formation of each micro-dot may be the same, and its marking effect cannot be fully demonstrated.

According to the technique disclosed in the second document, the micro-point anti-counterfeit coating is prepared by quantitative micro-spraying, and even micro-dots can be set in the micro-code characters or patterns, but the glue dots are not formed, and the shape of the micro-dots and each of the micro-dots are not limited. The number of micro-dots in the glue droplets, and then the planar coating is generally flat. In the case where the micro-dots are symmetrical, the marking effect cannot be fully exhibited, and there is little difference from the planar printing.

Although the technology disclosed in the third document is perfect on the basis of the first and second documents, there is still room for improvement:

The materials disclosed in the third document are relatively simple in material application, and the degree of fusion with the colloidal colloid is difficult to adjust and break through. Due to the limitation of the material itself, the microparticle identification degree of the preparation is limited to a certain extent. The choice of Epoxy Crystallization is translucent. Even under the 50x magnifying glass, the user is still not easy to identify. This technology uses a new type of Epoxy crystal. After UV curing, it is almost completely transparent. It is easier to identify for customers. Characteristics. In addition, the technical device disclosed in the third document is only declared as a 1200 can/min tank line, and the technology has upgraded the high-efficiency colloid valve technology to 500 times/second, which can be adapted to the application requirements of higher-speed pipelines. Finally, the technology disclosed in the third document requires the stop line feeding during the dispensing process of the epoxy gel to increase the downtime of the assembly line, and the technology is designed to supply the feeding device of the double side glue supply system, thereby realizing the non-stop line of the assembly line. Feeding, greatly reducing the line stop time.

The existing product identification code imparting technology includes laser coding, coding, and inkjet according to the need of independent of the automatic assembly line, or separate feeding of the product to realize the two-dimensional code of the product, and then by a separate visual reading. Take the detection system for reading detection. In the automated production line where the customer already has an independent control system, especially on the ultra-high-speed production line (10/sec-20/sec), the stop-changing line assignment and then the read detection will greatly affect the production efficiency. And because of the process of changing the line, it may also cause the product Quality problems may also cause secondary pollution to foods. At the same time, the separate detection and reading given by the product identification code is very likely to cause a large increase in the bit rate and low efficiency on the high-speed pipeline.

Although the technology disclosed in the third document is perfect on the basis of the first and second documents, there is still room for improvement: the materials disclosed in the third document are applicable to a single material, the degree of fusion with the colloid, and the dispersion. It is difficult to adjust and break through. Due to the limitation of the material itself, the microparticle identification of the fabric is limited to a certain extent. In addition, the selection of the existing epoxy gel crystal is translucent. Even under the 50x magnifying glass, the user is still not easy. Identification, and this technology uses a new type of epoxy crystals, almost completely transparent after UV curing, with features that are easier to identify for customers. In addition, the technical device disclosed in the third document is only declared as a 1200 can/min tank line, and the technology has upgraded the high-efficiency colloid valve technology to 500 times/second, which can be adapted to the application requirements of higher-speed pipelines. Finally, the technology disclosed in the third document requires the stop line feeding during the dispensing process of the epoxy gel to increase the downtime of the assembly line, and the technology is designed to supply the feeding device of the double side glue supply system, thereby realizing the non-stop line of the assembly line. Feeding, greatly reducing the line stop time.

Therefore, the existing product identification code imparting technology includes laser coding, inkjet coding, inkjet data need to be independent of the automatic assembly line, or separate feeding and feeding means to realize the identification code of the product, and then by a separate The visual reading detection system performs read detection. In the automated production line where the customer already has an independent control system, especially on the ultra-high-speed production line (10/sec-20/sec), the stop-changing line assignment and then the read detection will greatly affect the production efficiency. And because of the possibility of production during the change of line The quality of the product may also cause secondary pollution to food. Due to inefficiency, investment in equipment and floor space, labor input has been greatly increased, and a large amount of processing time has been incurred, resulting in greatly increased cost of product identification code. At the same time, the separate detection and reading of the product identification code on the high-speed pipeline is highly likely to cause a large increase in the bit rate. The prior art cannot design the association of the product identification code with the product fingerprint crystal, and cannot realize the anti-counterfeiting traceability function of one-to-one mutual authentication.
