Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a fast-read RFID device. Background Art

[0002] RFID is radio frequency identification, which is a contactless automatic identification technology based on the principle of radio frequency. RFID technology is becoming more and more mature, and there are multiple working frequency bands to choose from, suitable for different application fields. Compared with traditional identification methods (barcodes, magnetic cards, IC cards, etc.), RFID technology does not require direct contact, optical visibility, and human intervention to complete information input and processing.

[0003] Publication No. CN 212873499 U discloses a fast-reading RFID device. Through the first inspection door and the second inspection door, when the inspection items with RFID tags adapted to the RFID antenna pass through the first inspection door and the second inspection door, the magnetic field generated by the RFID antennas on both sides senses the information on the RFID tag, and sends the information to the RFID reader for reading and writing. The RFID reader sends the read and written information to the computer control end for relevant data processing. After the information of the inspection items is effectively processed, the micro motor is controlled to open the gate for feeding. When the information is read incorrectly, the gate is closed and the reason for the error is displayed on the data display screen. A voice alarm is set on the data display screen to alarm, reminding the staff to deal with it in time. The overall device can quickly read the item information, improve the circulation speed, reduce the labor intensity, and avoid the circulation of uninspected items. However, the patent still has the following problems in actual use:

[0004] Although the fast-read RFID device senses the information on the RFID tag through the magnetic field generated by the RFID antennas on both sides and sends the information to the RFID reader for reading and writing, it cannot ensure that the tag of the item is placed on one side of the RFID antenna when the inspection item is placed on the transmission device, and factors such as the distance, angle, and direction between the RFID reader and the tag will also affect the signal transmission quality, thereby affecting the card reading rate. Therefore, if the inspection item is placed in an askew position, it will affect the card reading rate of the RFID reader.

[0005] Therefore, a fast-read RFID device is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a fast-read RFID device to solve the problem proposed in the above-mentioned background technology that although the fast-read RFID device senses the information on the RFID tag through the magnetic field generated by the RFID antennas on both sides and sends the information to the RFID reader for reading and writing, when the inspection object is placed on the transmission device, it cannot ensure that the tag of the object is placed on one side of the RFID antenna, and factors such as the distance, angle, and direction between the RFID reader and the tag will also affect the signal transmission quality, thereby affecting the card reading rate.

By setting up an omnidirectional reading mechanism, not only can the starting motor be used to drive the main drive gear to rotate, but also the meshing connection between the main drive gear and the driven slave gear can be used to realize the self-rotation of the driven slave gear. Since the meshing gear ring is fixedly installed on the bottom of the fixed support plate, the meshing connection between the meshing gear ring and the driven slave gear can be used to realize the revolution of several driven slave gears, thereby driving the rotating plate to rotate.

[0023] 2. By setting the limit conveying mechanism, not only can the conveying motor be used to drive the sprocket transmission assembly and the conveying roller to rotate, but also the characteristics of the transmission connection between the conveying roller and the conveyor belt can be used to realize the conveying of the inspection items. By driving the unfolding motor to rotate the unfolding plate, the inspection items can be conveyed into the warehouse after being read and identified.

[0042] Working principle: Before using this fast-read RFID device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11As shown, first, the inspected article is placed on the conveyor belt 207, and the conveying motor 204 is used to drive the sprocket transmission assembly 205 and the conveying roller 206 to rotate. The characteristics of the transmission connection between the conveying roller 206 and the conveyor belt 207 are used to realize the conveyance of the inspected article. The unfolding motor 209 drives the unfolding plate 210 to rotate, and the inspected article can be conveyed into the warehouse after being read and identified. The limit rotating plate 226 can be used to preliminarily limit the inspected article when the inspected article is read, and the elastic force of the adjusting spring 222 is used to realize The second limit rotating rod 223 rotates, thereby adjusting the rotation angle of the limit rotating plate 226, so as to facilitate moving the inspected items to the middle part of the conveyor belt 207. By utilizing the elastic force of the limit spring 215, the limit sliding sleeve 214 and the limit support rod 216 can be moved, so as to further move the inspected items to the middle part of the conveyor belt 207. The angle of the first limit rotating rod 217 and the limit rotating plate 226 can be adjusted by adjusting the bolt 218, so as to adapt to the inspected items of different sizes and facilitate warehousing after reading and identification.

[0043] Secondly, the starting motor 104 is used to drive the driving main gear 105 to rotate, and the meshing connection between the driving main gear 105 and the driving slave gear 106 can be used to realize the self-rotation of the driving slave gear 106.

Due to the characteristics of meshing connection, the RFID reader 123 and the RFID antenna 124 can be raised and lowered while rotating. By changing the angles of the RFID reader 123 and the RFID antenna 124, the recognition effect of the RFID reader 123 and the RFID antenna 124 is improved. Since the number of teeth of the driving main gear 105 is much larger than the number of teeth of the driving main gear 105, the driving slave gear 106 can be rotated several times when the driving main gear 105 rotates one circle. Therefore, the RFID reader 123 and the RFID antenna 124 can be raised and lowered while the rotating disk 108 rotates, thereby realizing all-round detection of the inspected items, improving the reading efficiency, and achieving a fast reading effect.
