QR code ear mark laser marking technology

Animal husbandry is one of the important basic industries in China. The safety of animal husbandry is directly related to the safety and health of people’s daily diet. Therefore, food safety can not be relaxed for a moment. In order to effectively prevent and control major animal epidemics and ensure the quality and safety of livestock and poultry products, establishing a meat circulation traceability system of the whole industrial chain is the industry standard that animal husbandry producers in all places should meet.
In order to cooperate with this important industry standard of the state, relevant units quickly launched the two-dimensional code animal husbandry ear tag marked by laser and used it with a quality traceability system to further improve the management of animal husbandry products.
According to the report of the voice of China’s CCTV news, Hefei, Anhui Province, has taken the lead in implementing electronic animal quarantine since March 15, 2013, so as to realize the “production record, information query and flow traceability” of livestock products. Using the anti-counterfeiting mark with two-dimensional code ear tag on the machine printed quarantine certificate is like wearing an “electronic ID card” to live pigs, so as to realize the online recording of the data of the whole process of livestock from birth to slaughter, so as to prevent some live pig operators from using fake certificates to fill in the quarantine certificate manually.
What is a two-dimensional code ear tag?
The two-dimensional code ear tag is an information storage element of the animal identification traceability system. The animal is hung on the ear at birth. From then on, the birth, immunization, quarantine, transportation, slaughter and other file information of the animal from life to death will be stored in the ear tag. These information is 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 network management of animal epidemic prevention and animal derived food safety information.
How to know the two-dimensional code livestock and poultry logo?
Each set of two-dimensional code livestock and poultry identifications consists of two parts: the main mark and the auxiliary mark. The front of the main mark carries coding information, which consists of two parts: two-dimensional bar code and digital coding. The number code is 15 digits in total and consists of animal species + division code + identification sequence number. Among them, the first bit represents the livestock (1 pig, 2 cattle and 3 sheep), the second to seventh bits represent the division code, and the eighth to fifteenth bits represent the unique code.
Principle and advantages of two-dimensional code ear mark laser marking?
The two-dimensional code ear tag laser marking technology uses the computer-controlled high-energy density laser beam to act on the ear tag surface to be marked according to the predetermined trajectory, so that the surface material can be instantaneously vaporized or chemically changed to change the color, etch words and patterns with a certain depth or color, and leave permanent marks on the ear tag surface.
On the one hand, laser marking two-dimensional code has the characteristics of small size, high density, large capacity and low cost, which is suitable for marking on small parts such as ear tags. On the other hand, laser marking is permanent and anti-counterfeiting, and the two-dimensional code of the laser mark can be correctly read even when it is worn or defaced.
In addition, the laser marked two-dimensional code livestock and poultry identification uses an encrypted industry-specific code with anti-counterfeiting function, which can facilitate consumers to query the authenticity on the animal health supervision network, and accurately query various information such as pig origin and quarantine officer.
