Description

An electronic ear tag using a coupling ring

technical field

The utility model relates to an electronic ear tag, in particular to an electronic ear tag using a coupling ring.

Background technique

In the RFID system, the electronic tag has always been an important part, and according to the use and installation environment, the system also has different requirements for the structure and performance of the electronic tag. In farming and animal husbandry management, it is necessary to put electronic ear tags on the ears of livestock. Ear tags are always accompanied by the life cycle of livestock and can uniquely identify livestock.

In farming and animal husbandry management, dairy cow management is a very important application. A dairy cow usually serves for 5 to 8 years in a clothing farm. Therefore, the service life of the electronic tags used to manage dairy cows on the farm should be at least more than 8 years. However, the currently used electronic tags usually adopt the reverse packaging process to bond the unpackaged chip to the tag antenna through conductive adhesive to form the label inlay, and then package the inlay into the plastic shell. Due to the material characteristics of the conductive adhesive after the chip is mounted It is relatively brittle and not resistant to bending; and the chip without package is exposed, and it will be damaged by a slight impact. However, when the ear tag is hung on the cow's ear, the ear tag is sometimes caught in the railing and pulled out forcibly by the cow. In addition, some cattle will chew the electronic tag. These situations will cause the electronic ear tag to be bent and rubbed repeatedly. The connection between the electronic tag chip and the antenna is loose or the tag chip is damaged, which greatly reduces the service life of the electronic tag. The application of ear tags in agricultural and animal husbandry management is limited.
