High power uv laser marking livestock two-dimensional code ear tags

Animal husbandry is one of the important basic industries in our country. The safety of animal husbandry is directly related to the safety and health of people's daily diet. Therefore, food safety issues must not be relaxed for a moment. In order to effectively prevent and control major animal diseases and ensure the quality and safety of livestock and poultry products, the establishment of a meat circulation traceability system for the entire industry chain is an industry standard that local livestock producers should meet.

In order to comply with this important national industry standard, relevant units quickly launched the two-dimensional code animal husbandry ear tags with laser marking, and used it with a quality traceability system to further improve the management of animal husbandry products.

UV laser marking production has records, information can be queried, and flow can be traced

According to a report by Voice of China "Yangguang News", in order to realize that livestock products have "recorded production, queryable information, and traceable flow", starting from March 15, 2013, Hefei, Anhui, took the lead in implementing electronic animal quarantine expeditions, realizing the availability of livestock products. Traceability system. The use of machine-printed quarantine certificates with two-dimensional code ear tags on the anti-counterfeiting logo is like wearing an "electronic ID card" for live pigs, realizing online data recording of the entire process of livestock from birth to slaughter, to prevent some live pig operations when filling in the quarantine certificate manually Households use false certificates to take advantage of the loopholes.

What is a QR code ear tag?

The two-dimensional code ear tag is an information storage element of the animal identification traceability system, and the animal is hung on the ear as soon as it is born. From then on, the animal’s birth, immunization, quarantine, transportation, slaughter and other archive information from birth to death will all be stored in the ear tag. These information are compiled into a unique two-dimensional code, and after being translated by the reader, the information will be transmitted to the central database to realize the networked management of animal epidemic prevention and animal-derived food safety information.

 How to recognize the two-dimensional code livestock and poultry logo?

Each set of two-dimensional code livestock and poultry logos consists of two parts: the main label and the auxiliary label. The front of the main label carries the coding information, and the coding information consists of two parts: a two-dimensional bar code and a digital code. The digital code has a total of 15 digits and is composed of animal species + division code + identification sequence number. Among them, the first digit represents the breed of livestock (1 pig, 2 cattle, 3 sheep), the 2-7 digits are the division codes, and the 8-15 digits are the unique codes.

Principles and advantages of laser marking of two-dimensional code ear tags?

The two-dimensional code ear tag laser marking technology uses a computer-controlled high-energy density laser beam to act on the surface of the ear tag that needs to be marked according to a predetermined trajectory, so that the surface material is instantly vaporized or chemically changed to change the color and etched Texts, patterns, etc. with a certain depth or color to leave a permanent mark on the surface of the ear tag.

On the one hand, laser-marked two-dimensional codes have the characteristics of small size, high density, large capacity, and low cost, and are suitable for marking on small parts such as ear tags. On the other hand, laser marking is permanent and anti-counterfeiting. Even when it is worn or defaced, the laser-marked two-dimensional code can be read correctly.

The laser-marked two-dimensional code livestock and poultry logo has anti-counterfeiting function

In addition, the laser-marked two-dimensional code livestock and poultry identification uses an encrypted industry-specific code, which has an anti-counterfeiting function, which can facilitate consumers to inquire about the authenticity of the animal health supervision network, and accurately query various information such as pig origin, quarantine officer, etc. .
