RFID (radio frequency identification device) antenna detection device and application thereof

Abstract

The invention provides an antenna detection device which is used for detecting an RFID (radio frequency identification device) antenna and comprises a decoiling device, a coiling device, a static clamping assembly, a vacuum absorption assembly, an appearance detection device, a resistance detection device and a dynamic clamping assembly; the static clamping assembly, the vacuum absorption assembly, the appearance detection device, the resistance detection device and the dynamic clamping assembly are sequentially arranged between the decoiling device and the coiling device; an antenna substrate decoiled by the decoiling device is conveyed to the detection position through the dynamic clamping assembly; the static clamping assembly clamps the antenna substrate after the dynamic clamping assembly loosens the antenna substrate; the antenna substrate is adsorbed on a detection support panel by the vacuum absorption assembly and then is respectively detected by the appearance detection device and the resistance detection device; and after the detection, the coiling device recoils the detected antenna substrate. The invention also discloses steps for utilizing the antenna detection device to perform RFID antenna detection. According to the invention, the antenna detection device can detect overall dimension of the RFID antenna and defects including conglutination, burr, disconnection, sand holes and the like. Besides, the antenna detection device has high precision, high efficiency and strong adaptability and can detect RFID antennas with different types and different dimensions.

Description

technical field [0001] The invention belongs to the field of radio frequency identification tag detection, and in particular relates to an RFID antenna detection device and a process method thereof. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. RFID tags have the advantages of waterproof and antimagnetic, large storage capacity, long service life, strong anti-interference ability, long distance and high degree of intelligence that barcodes do not have. They are widely used in logistics, commodity tracking, manufacturing process control, supply chain management, and retail systems. , automatic payment system and other fields have broad application prospects. [0003] The RFID tag is composed of a tag antenna and a tag chip package. As a device that receives and emits electromagnetic waves, the tag antenna is a key component in a wireless communication system. The performance of the RFID system larg...

Problems solved by technology

[0008] The disadvantage of existing software detection equipment is that it is time-consuming to achieve high detection accuracy, which reduces the real-time performance of detection

In addition, when the device does not communicate with the terminal, it cannot be detected. When all antennas of the device are abnormal, it cannot be detected due to the loss of reference standards. This method is applicable to limited types of antennas.
