[0002] With the rapid development of the Internet of Things (IoT), radio frequency identification (RFID), as one of its core technologies, is playing a vital role in a variety of fields, including logistics, manufacturing, and healthcare. RFID technology uses radio waves to automatically identify objects and capture data, significantly improving the efficiency and accuracy of data collection, reducing manual intervention, and lowering costs. In the logistics industry in particular, the application of RFID technology not only optimizes cargo tracking and management processes but also enhances supply chain transparency and responsiveness.

[0003] Existing RFID systems still face several challenges in practical application. Traditional RFID devices are often bulky and complex to install, making them unsuitable for deployment in space-constrained environments. Existing systems also have limited directional recognition capabilities, making it difficult to accurately identify fast-moving objects. Furthermore, RFID systems require additional functional structures to be effectively used in logistics sorting systems, limiting their widespread adoption.

[0004] Therefore, developing an efficient RFID identification device that is compact, easy to install, and can be flexibly adjusted to adapt to different production environments has become an urgent problem to be solved in the industry. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0028] See also Figure 1-4 As shown, the present invention is a radio frequency identification device. The entire device is installed on a belt conveyor or a continuous plate conveyor assembly line. Goods on the assembly line enter the device at regular intervals. All or some of the goods on the assembly line are affixed with radio frequency tags. The device identifies each tagged item that passes through, and the device performs a reversal or non-reversal operation on the identified goods.

[0029] The system consists of a frame 1, a horizontal conveyor platform 2, an RFID reader 3, and a deflection guide 4. The horizontal conveyor platform 2 is mounted horizontally on the frame 1. The RFID reader 3 is mounted on one side of the frame 1 via a mounting plate 5 and is located at the input end of the horizontal conveyor platform 2. The RFID reader 3 identifies incoming RFID-tagged goods at the front end. The deflection guide 4 deflects the goods and resets them after the goods exit the horizontal conveyor platform 2.

[0030] The deflection guide 4 comprises a square tube 41, a deflection guide row 42, a cylinder 43, a slider 44, a guide rod 45, a connecting rod 46, and a pin 47. The square tube 41 is fixed to the frame 1. A rectangular through-hole 411 is provided on the side of the square tube 41 facing the horizontal conveyor 2. One end of the deflection guide row 42 passes through the rectangular through-hole 411 and is rotatably mounted to one end of the square tube 41 via a pin 47, which is positioned at the input end of the horizontal conveyor 2. The cylinder 43 is mounted on the other end of the square tube 41. The guide rod 45 is fixed to the inner wall of the square tube 41. The slider 44 is slidably mounted on the guide rod 45. The free end of the cylinder 43 is fixedly connected to the slider 44 by bolts. The connecting rod 46 connects the slider 44 to the deflection guide row 42. The deflection guide row 42 comprises a U-shaped channel plate 421 with a side opening. A circular tube 422, which mates with the pin 47, is fixed to one end of the U-shaped channel plate 421. A row of rollers 423 are installed between the upper and lower walls of the U-shaped groove plate 421. The bottom surface of the square tube 41 is fixed with an internal threaded round seat 412 that is threadedly connected to the pin 47. The top surface of the square tube 41 is provided with a pin hole that is coaxially arranged with the internal threaded round seat 412 and is used to insert the pin 47.

[0031] The telescopic movement of cylinder 43 drives slide 44 to move linearly on guide rod 45. Slide 44 drives connecting rod 46 to move, thereby driving the deflection of deflection guide row 42. Cylinder 43 has a fast response speed, and the row of rollers 423 on deflection guide row 42 helps to reduce friction between the deflection guide row 42 and the cargo, facilitating rapid reversal of cargo on horizontal conveyor platform 2.

[0032] The frame 1 includes four rectangular sleeve tubes 11 arranged at the four corners of a rectangle, and the two rectangular sleeve tubes 11 in the length direction of the rectangle are connected by two parallel first fixed links 12, and the two rectangular sleeve tubes 11 in the width direction of the rectangle are connected by a second fixed link 13. The mounting base plate 5 is fixedly mounted on the outer side of one of the rectangular sleeve tubes 11. The horizontal conveyor platform 2 includes an active roller and a driven roller 22 mounted on the frame 1 through seat bearings. A horizontal conveyor belt 21 is wound around the active roller and the driven roller. A motor 22 for driving the active roller is also mounted on the frame 1. A row of rectangular vertical plates 14 is fixed on the upper first fixed link 12. Horizontal support plates 15 for supporting the upper part of the horizontal conveyor belt 21 are fixed on the opposite inner sides of the two rows of rectangular vertical plates 14. The overall structure of the frame 1 is stable, and the provision of the horizontal support plates 15 helps to increase the load-bearing capacity of the horizontal conveyor belt 21.

[0033] To facilitate height adjustment of the entire RFID device to match existing production lines, a row of pre-tightening bolts 16 are fixed through the side wall of the rectangular sleeve tube 11. An adjustable support leg 6 is installed at the lower end of each of the four rectangular sleeve tubes 11. The adjustable support leg 6 includes a rectangular column 61 that plugs into and fits with the rectangular sleeve tube 11. A flange 62 is fixed to the lower end of the rectangular column 61. By adjusting the extension of the adjustable support leg 6, the height of the upper surface of the horizontal conveyor belt 21 can be adjusted to suit the height of the existing assembly line. The position of the adjustable support leg 6 can be fixed by tightening the pre-tightening bolts 16.
