[0002] Radio frequency identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and the specific target. Electronic tags and readers made using RFID technology are widely used, especially electronic tags as nodes of the Internet of Things, which can effectively store various information of attached items and transmit this information through communication with readers.

[0004] With respect to the above-mentioned related technologies, the inventors found that the classification guide mechanism is driven by gear meshing to drive the mounting frame to swing. The slow swinging speed also requires the conveyor belt to rotate at a low speed, which will lead to low operating efficiency of the entire device and low efficiency in radio frequency tag recovery.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0022] Embodiment: This application proposes a radio frequency tag recovery device for a product anti-counterfeiting system, referring to Figure 1 and 2 The device includes a material conveyor belt 1, a radio frequency tag identifier 2, a material pushing component 3, a material receiving component 4 and a controller 5.

[0023] The material conveyor belt 1 is used to convey the radio frequency tags that need to be recycled. The radio frequency tags are placed on the material conveyor belt 1 one by one for transmission. A second material receiving container is provided at the end of the material conveyor belt 1. The second material receiving container 6 is used to collect the good radio frequency tags conveyed on the material conveyor belt 1. The radio frequency tag identifier 2 is installed just above the middle of the material conveyor belt 1 through a bracket. There is a scanning area on the material conveyor belt 1 for scanning and identifying radio frequency tags. In this embodiment, the radio frequency tag identifier 2 is used to identify defective tags, that is, unqualified products. When the radio frequency tag identifier 2 scans a defective tag, it will send a response signal. The controller 5 is installed on one side of the material conveyor belt 1. The radio frequency tag identifier 2 is electrically connected to the controller 5. The controller 5 is used to receive and process the response signal sent by the radio frequency tag identifier 2, and send a control command according to the response signal.

[0024] The pushing assembly 3 and the receiving assembly 4 are relatively installed on both sides of the material conveyor belt 1. The pushing assembly 3 and the receiving assembly 4 are arranged one to one. One or more groups of the pushing assembly 3 are arranged along the transmission direction of the material conveyor belt 1 to avoid the occurrence of missed inspection of defective product labels.

[0025] The push assembly 3 includes a push cylinder 31 and a push plate 32. The push plate 32 is set as a rectangular plate and installed at the end of the piston rod of the push cylinder 31. The push cylinder 31 is installed on the mounting frame of the material conveyor belt 1 through a bracket. The push cylinder 31 is connected with an air pipe and an air pump. The air pump is used to execute the control command issued by the controller 5 to extend the piston rod of the push cylinder 31. In this embodiment, the piston rod axis of the push cylinder 31 is parallel to the upper surface of the material conveyor belt 1, and the pushing direction of the push plate 32 is at an acute angle to the material conveying direction of the material conveyor belt 1. The area where the push plate 32 moves is the scanning area, and the push plate 32 pushes the defective label obliquely backward in the scanning area.

[0026] Reference Figure 1 and 3 The material receiving assembly 4 includes a material receiving chute 41 and a first material receiving container 42. The inlet end of the material receiving chute 41 corresponds to the pushing cylinder 31. The material receiving chute 41 is used to receive the defective labels pushed down from the material conveyor belt 1 by the pushing plate 32. The first material receiving container 42 is arranged at the end of the material receiving chute 41 to receive the defective labels sliding down from the material receiving chute 41.

[0027] In this embodiment, the material receiving chute 41 is configured as a herringbone structure, including an uphill section and a downhill section. The corner is configured as the highest point. The lowest end of the uphill section is configured adjacent to the material conveyor belt 1, and the lowest end of the downhill section is also close to the material conveyor belt 1. The first material receiving container 42 is configured below the material conveyor belt 1.

[0028] In order to prevent the radio frequency tag from sliding off the receiving chute 41, baffles 43 are arranged on both sides of the receiving chute 41 in this embodiment. The baffles 43 at the corners are parallel to the transmission direction of the material conveyor belt 1. An elastic buffer assembly is arranged on the inner side of the baffles 43 at the corners. The elastic buffer assembly includes an elastic member 44 connected to the baffle 43 and a contact plate 45 connected to the side of the elastic member 44 away from the baffle 43. In this embodiment, the elastic member 44 is a spring, and the contact plate 45 is used to contact the radio frequency tag.

[0029] After the push plate 32 quickly pushes out the defective label, the defective label will quickly slide upward along the upslope section of the material receiving chute 41 and hit the contact plate 45 at an inclined angle. The contact plate 45 squeezes the elastic member 44 to offset the impact of the defective label and reduce the moving speed of the defective label. The elastic force of the elastic member 44 is then used to pop the defective label out in the opposite direction, causing the defective label to slide downward along the downslope section of the material receiving chute 41 and fall into the first material receiving container 42.

[0030] In this embodiment, the cross section of the contact plate 45 is L-shaped, including a vertical plate and a horizontal plate whose upper end is bent away from the elastic member 44. The horizontal plate can prevent the defective label from bouncing upward and derailing.

[0031] The implementation principle of the embodiment of the present application is as follows: the radio frequency tag is conveyed on the material conveyor belt 1, and the radio frequency tag identifier 2 is used to identify and scan the radio frequency tag transmitted on the material conveyor belt 1. Once the tag is identified as a defective product by the radio frequency tag identifier, it will be marked. The radio frequency tag identifier 2 sends a signal to the controller 5, and the controller 5 receives and processes the sensing signal, and sends a control command to the air pump motor. The air pump works to control the pushing cylinder 31 to push out quickly, push the defective label into the receiving slide 41, and slide along the herringbone slide, and further transport it to the second receiving container. The good label is not identified and marked by the radio frequency tag identifier, continues to be transmitted on the material conveyor belt, and finally falls into the first receiving container, finally realizing the classified recycling of the radio frequency tags.

[0032] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
