Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic identification, and in particular relates to an RFID-coded article identification device. Background Art
[0002] RFID is based on contactless data communication between a reader and a tag to identify a target. RFID has a wide range of applications, including animal chips, automotive chip anti-theft devices, access control, parking lot management, production line automation, and material management. RFID is a type of automatic identification technology that uses radio frequency (RF) for contactless, two-way data communication. It uses RF to read and write to recording media (electronic tags or radio frequency cards) to identify targets and exchange data. It is considered one of the most promising information technologies of the 21st century.
[0003] During the production process of RFID-encoded items, some desktop devices' RFID encoding and detection are out of sync, making it impossible to distinguish between good and bad products. Good and bad products need to be re-inspected separately. At the same time, RFID tags that fail encoding cannot be marked, resulting in poor identification effect, affecting subsequent production progress and low work efficiency. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an RFID-coded item identification device, which effectively solves the problems of poor identification effect and low work efficiency.
[0005] The technical solution to the technical problem is as follows: the machine comprises a frame, a conveyor belt is provided on the frame, a plurality of racks are evenly fixed on the inner surface of the conveyor belt, a first gear and a second gear are rotatably connected to the frame, the first gear and the second gear are respectively meshed with the racks, a sheave is coaxially fixed to the first gear, a transmission shaft is rotatably connected to the frame, an active dial is coaxially fixed to the transmission shaft, and a cylindrical pin is fixed on the active dial that intermittently meshes with the sheave;
[0006] Multiple partitions are evenly fixed on the outer surface of the conveyor belt, and work stations are formed between adjacent partitions. Items are placed on the work stations, and the items have built-in RFID tags. A discharge bin, a reader and an electric push rod are installed on the rack. The reader is located between the discharge bin and the electric push rod, the reader is located above the item, and the electric push rod is located in front of the item.
[0007] Preferably, the first gear is located on the right side of the conveyor belt, and the second gear is located on the left side of the conveyor belt.
[0008] Preferably, a motor is mounted on the frame, and the motor is coaxially fixedly connected to the transmission shaft via a reducer.
[0009] Preferably, the multiple articles are stacked up and down in the discharge bin, and the height of the articles is greater than the height of the partition.
[0010] Preferably, a first collecting box located on the right side of the conveyor belt is fixed on the frame.
[0011] Preferably, a slideway located at the rear side of the electric push rod is fixed on the frame, the slideway is inclined, and a second collection box connected to the bottom of the slideway is fixed on the frame.
[0012] Compared with traditional equipment, the present invention has the following advantages: 1) The structure is ingenious. By making the height of the article greater than the height of the partition, multiple articles are stacked up and down in the discharge bin. In the process of the conveyor belt driving the articles in the workstation to move to the right, the articles in the discharge bin can fall into the next workstation in an orderly manner, and the material is automatically unloaded with low cost and high stability; 2) The reader and the electric push rod are combined. The reader can read the coded RFID tag. When the reader cannot read the RFID tag, the article is defective, and the electric push rod can screen out the defective products. It is convenient and fast, and the identification effect is good; 3) The groove wheel mechanism is adopted, which is stable and can control the intermittent rightward movement of the conveyor belt, which not only ensures the working time of the reader and the electric push rod, but also realizes the transportation of the conveyor belt. The combination effect is good, the assembly line operation is high, and the work efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.
[0018] Depend on Figures 1 to 3An RFID-coded item identification device is provided, comprising a frame 1, a conveyor belt 2 being provided on the frame 1, a plurality of racks 3 being uniformly fixed to the inner surface of the conveyor belt 2, a first gear 4 and a second gear 5 being rotatably connected to the frame 1, the first gear 4 and the second gear 5 being respectively engaged with the racks 3, a sheave 6 being coaxially fixed to the first gear 4, a transmission shaft 7 being rotatably connected to the frame 1, a driving dial 8 being coaxially fixed to the transmission shaft 7, a cylindrical pin 9 being fixed to the driving dial 8 and intermittently engaged with the sheave 6;
[0019] A plurality of partitions 10 are evenly fixed on the outer surface of the conveyor belt 2, and a work station is formed between two adjacent partitions 10. An object 11 is placed on the work station, and the object 11 has an RFID tag built into it. A discharge bin 12, a reader / writer 13 and an electric push rod 14 are installed on the frame 1. The reader / writer 13 is located between the discharge bin 12 and the electric push rod 14, the reader / writer 13 is located above the object 11, and the electric push rod 14 is located in front of the object 11.
[0020] In order to ensure that the conveyor belt 2 is in a taut state, the first gear 4 is located on the right side of the conveyor belt 2 , and the second gear 5 is located on the left side of the conveyor belt 2 .
[0021] In order to ensure the appropriate rotation speed of the active dial 8, a motor 15 is installed on the frame 1, and the motor 15 is coaxially fixedly connected to the transmission shaft 7 via a reducer.
[0022] In order to facilitate the sequential placement of the articles 11 on the workstations and avoid interference between the articles 11 and the partitions 10 , the multiple articles 11 are stacked up and down in the discharge bin 12 , and the height of the articles 11 is greater than that of the partitions 10 .
[0023] In order to facilitate the collection of qualified articles 11 , a first collection box 16 is fixed to the frame 1 and is located on the right side of the conveyor belt 2 .
[0024] In order to facilitate the collection of unqualified articles 11 , a slide 17 located at the rear side of the electric push rod 14 is fixed on the frame 1 . The slide 17 is tilted, and a second collection box 18 connected to the bottom of the slide 17 is fixed on the frame 1 .
[0025] When the utility model is in use, multiple items 11 are stacked up and down in the discharge bin 12, the item 11 at the bottom is in the work station, the motor 15 is started, the motor 15 drives the transmission shaft 7 to rotate through the reducer, the transmission shaft 7 drives the active dial 8 to rotate coaxially, to ensure the appropriate rotation speed of the active dial 8, the active dial 8 drives the groove wheel 6 to rotate intermittently at a certain angle through the cylindrical pin 9, and taking the groove wheel 6 intermittently rotating 90° as an example, when the groove wheel 6 drives the first gear 4 to rotate coaxially and intermittently 90°, the first gear 4 drives the conveyor belt 2 to move to the right by a distance of a work station through the rack 3, the second gear 5 is the driven wheel, the second gear 5 is located on the left side of the conveyor belt 2, and the first gear 4 is located on the conveyor belt 2, to ensure the stability of the intermittent rightward movement of the conveyor belt 2. The conveyor belt 2 intermittently moves to the right by a distance of a station. Since the height of the article 11 is greater than the height of the partition 10, during the process of the article 11 in the station moving to the right, the article 11 in the station can support the article 11 at the bottom of the discharge bin 12, thereby preventing the article 11 at the bottom of the discharge bin 12 from interfering with the partition 10. As the conveyor belt 2 continues to move to the right, the article 11 in the station is separated from the article 11 at the bottom of the discharge bin 12, thereby causing the article 11 at the bottom of the discharge bin 12 to fall into the next station in an orderly manner, thereby realizing automatic unloading without the need for additional equipment, low cost, and economical and durable;
[0026] When the item 11 in the workstation moves to the bottom of the reader 13, the item 11 has an internal RFID tag. The reader 13 is equipped with a transceiver antenna, a frequency generator, and a microprocessor. The frequency generator generates a frequency, and the antenna sends a radio frequency signal to the RFID tag for encoding, and receives a response signal and tag information returned by the RFID tag. If the response signal of the RFID tag is not received, it is regarded as an unqualified item 11. When the unqualified item 11 intermittently moves to the electric push rod 14, the electric push rod 14 pushes the unqualified item 11 backward to the slide 17. The item 11 falls into the second collection box 18 through the slide 17. The electric push rod 14 is immediately reset, and the qualified item 11 continues to move to the right with the conveyor belt 2 and falls into the first collection box 16. The operation is simple, the identification effect is good, and it is easy to distinguish.
[0027] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
