Description

Technical Field

[0001] The utility model belongs to the technical field of RFID identification, and in particular relates to an identification device based on RFID technology. Background Art

[0002] RFID is a non-contact automatic identification technology that automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require human intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple electronic tags at the same time. It is quick and convenient to operate and is frequently used in supermarkets.

[0003] The existing patent number is CN209980264U, and the public name is a multi-recognition range identification device based on UHF RFID technology. The adopted technical solution is: including a conveyor belt, a first identification group, a second identification group, a third identification group, a fourth identification group, goods, an RFID tag, a main identification unit, and a sub-identification unit.

[0004] Although the above-mentioned identification device can effectively expand the identification distance through high-gain antennas and high-power identification modules, and form multiple identification ranges through a self-coordinated composite identification unit array, it can perform various forms of identification, reduce mutual interference among identification units, and automatically select and adapt the optimal identification unit for the tag to be identified, thereby obtaining the best identification effect, effectively improving the problem of reduced identification efficiency caused by the disorderly placement of items, and is suitable for identification needs at a longer distance. At the same time, through the analysis of the identification results of each identification unit, the direction of cargo transportation can be independently determined, which is convenient for dynamic monitoring of cargo transportation. However, the above-mentioned identification device identifies cargo through multiple identification groups, which increases the production cost and utilization rate of the identification device, and the above-mentioned identification device is not convenient for arranging cargo, thereby reducing the efficiency of identification.

At this time, the limiting guide mechanism 5 will limit and guide the goods on the surface of the electric conveyor belt 2, and move the goods along the center line position of the electric conveyor belt 2, so as to reduce the probability of goods deviation affecting identification. Then the anti-static fan 8 will remove static electricity from the label on the surface of the goods, and the label of the goods will be identified by the identification mechanism 6.

[0026] Specifically, the limiting guide mechanism 5 includes a mounting base 501 installed on the upper surface of the support frame 1, a bidirectional electric cylinder 502 is installed on the surface of the mounting base 501, and movable plates 503 are installed on the surfaces of the piston rods on both sides of the bidirectional electric cylinder 502. A connecting base 504 is installed at the bottom of the movable plate 503, and the bottom of the connecting base 504 is rotatably connected to a guide electric rail 505. A first servo motor 506 is installed on the upper surface of the connecting base 504, and the output shaft of the first servo motor 506 is fixedly connected to the surface of the guide electric rail 505.

[0027] In a specific embodiment of the utility model, when the bidirectional electric cylinder 502 is started, it will drive the movable plate 503 and the connecting seat 504 to move. At this time, the moving trajectory of the goods can be limited by the guide electric rail 505. When the guide angle of the guide electric rail 505 needs to be adjusted, the first servo motor 506 is started, and the output shaft of the first servo motor 506 drives the guide electric rail 505 to rotate, thereby adjusting the guide angle of the guide electric rail 505.

[0034] Working principle: Place the goods with the label facing upwards on the surface of the electric conveyor belt 2, and the goods can be transported by the electric conveyor belt 2. When the bidirectional electric cylinder 502 is started, it will drive the moving plate 503 and the connecting seat 504 to move. When the moving plate 503 moves, it will move on the surface of the blocking plate 508, thereby increasing the stability of the moving plate 503 during movement. At the same time, the guide rod 507 will reduce the probability of the moving plate 503 falling off the surface of the blocking plate 508. At this time, the moving trajectory of the goods can be limited by the guide rail 505. When the guide angle of the guide rail 505 needs to be adjusted, the first servo motor 506 is started, and the output shaft of the first servo motor 506 drives the guide rail 505 to rotate, thereby adjusting the guide angle of the guide rail 505.

Then, the anti-static fan 8 removes static electricity from the label on the surface of the goods, and the label of the goods is identified by the RFID identifier 605. When it is necessary to adjust the identification height of the RFID identifier 605, the second servo motor 606 is started, and the output shaft of the second servo motor 606 drives the threaded rod 603 to rotate. At this time, the internal thread plate 604 moves under the action of the thread on the surface of the threaded rod 603. At this time, the label can be identified by the RFID identifier 605, and the internal thread plate 604 moves while driving the guide block 608 to move on the surface of the guide rail 607, thereby increasing the stability of the internal thread plate 604 when moving.
