[0041] In this embodiment, the preferred read-write component has two operating modes:

[0042] In the first operation mode of the read-write component, the RFID tag is pushed to the top of the first read-write device 22 through the reciprocating motion of the propulsion mechanism 4. When the first trigger optical fiber 221 detects that there is an RFID tag on the first read-write device 22, the first trigger optical fiber 221 transmits a signal to the control system, and the control system transmits a start signal to the first read-write device 22. The first read-write device 22 reads the EPC code of the RFID tag above, and the first read-write device 22 transmits the read EPC code to the control system, so that the control system compares whether the EPC code is complete. If the EPC code is inconsistent, the RFID tag is judged to be NG, and if the EPC code is consistent, the RFID tag is judged to be OK; the reciprocating motion of the propulsion mechanism 4 pushes the detected RFID tag to the top of the second read-write device 23, and the second read-write device 2 stops running;

[0043] In the second operation mode of the read-write component, the RFID tag is pushed to the top of the first read-write device 22 by the reciprocating motion of the propulsion mechanism 4.

The second trigger optical fiber 231 transmits a signal to the control system, and the control system transmits the start signal to the second read-write device 23. The second read-write device 23 reads the EPC code in the RFID tag above, and the second read-write device 23 transmits the read EPC code to the control system, so that the control system compares whether the written EPC code is consistent with the read EPC code. If the EPC codes are inconsistent, the RFID tag is determined to be NG, and if the EPC codes are consistent, the RFID tag is determined to be OK.

[0044] Please refer to Figure 5 .

[0045] The NG unloading mechanism 6 includes an air blowing pipe 61, a first slide rail 62, two first sliders 63 and an NG unloading box 64. The air blowing pipe 61 is placed on the workbench 2, and the air blowing pipe 61 is electrically connected to the control system. The air outlet of the air blowing pipe 61 faces the NG unloading port 24; the first slide rail 62 is placed in the workbench 2, and an adjustment seat is extended on one side of the first slide rail 62. The bottom of the first slider 63 is slidably connected to the first slide rail 62, and the NG unloading box 64 is fixedly connected to one of the first sliders 63. An opening is opened on the NG unloading box 64, and the opening faces the NG unloading port 24. The top of the first slider 63 is fixedly connected to the cylinder 631, and the cylinder 631 is electrically connected to the control system. The output shaft of the cylinder is fixedly connected to a support plate, and the support plate is located in the NG unloading port 24. The two support plates are respectively located on both sides of the inner wall of the NG unloading port 24. The output shaft of the cylinder 631 pushes the support plate to rise so that the top of the support plate is flush with the top of the transmission channel 21; the slider extends with a first push rod 632, and the first push rod 632 is slidably connected to the adjustment seat, and the first push rod 632 on one first slider 63 is slidably connected to the other first slider 63;

[0046] By pulling or pushing the two first push rods 632, the two first sliders 63 are respectively slid on the first slide rails 62, so that the two first sliders 63 are moved closer to each other or farther away from each other, thereby adjusting the distance between the two support plates so that the two support plates just support the bottom of the RFID tag close to both sides;

[0047] The detected RFID tags are moved to the top of the two support plates through the reciprocating motion of the propulsion mechanism 4. When the detection result of the RFID tags above the two support plates is NG, the control system transmits a stop signal to the cylinder 631. The output shaft of the cylinder 631 pulls the support plate down, so that the RFID tags above the two support plates sink into the NG discharge port 24. The control system transmits a running signal to the air blowing pipe 61. The air blowing pipe 61 blows out gas from the air outlet to blow the RFID tags below into the NG discharge box 64. After the screening is completed, the control system transmits a running signal to the cylinder 631. The output shaft of the cylinder 631 pushes the support plate up, so that the top of the support plate is flush with the top of the transmission channel 21. The control system transmits a stop signal to the air blowing pipe 61, and the air blowing pipe 61 stops the gas eruption. When the detection results of the RFID tags above the two support plates are OK, the output shaft of the cylinder 631 pushes the support plates up so that the tops of the support plates are flush with the tops of the transmission channel 21, allowing the RFID tags to maintain their current position, and the RFID tags with OK detection results are pushed away from the top of the NG unloading port 24 through the propulsion mechanism 4.

[0048] Please refer to Figure 6 .

[0049] The OK unloading mechanism 7 is connected to the workbench 2, the OK unloading mechanism 7 is close to the other end of the transmission channel 21, and the NG unloading port 24 is located between the read-write component and the OK unloading mechanism 7; the OK unloading mechanism 7 includes an OK unloading box 71, two partitions 711, a second slide rail, a second slide block 72 and a connecting bracket 74; in this embodiment, the inner wall of the OK unloading box 71 is preferably arc-shaped, one end of the OK unloading box 71 is fixedly connected to the workbench 2, the partition 711 is placed in the OK unloading box 71, the outer side of the partition 711 fits the arc-shaped inner wall of the OK unloading box 71, and the two sides of the unloading box are slidably connected with a second push rod 712, one end of the second push rod 712 penetrates into the OK unloading box 71, and one end of the second push rod 712 is fixedly connected to the partition 711, and a unloading channel is formed between the two partitions 711, and the unloading channel is close to the transmission channel 21;

[0050] By pulling or pushing the two second push rods 712 to slide the two partitions 711 in the OK material box 71, the width of the material channel between the two partitions 711 is adjusted, so that the material channel can limit the RFID tags to be neatly arranged after falling into the material channel;

[0051] Furthermore, the second slide rail is placed on one side of the workbench 2, and one side of the second slider 72 is rotatably connected to a fourth roller, and the fourth roller is in sliding contact with the third cam 34, and the other side of the second slider 72 is slidably connected to the second slider 72, and the top of the second slider 72 is fixedly connected to an adjusting rod, and a plurality of paddles 721 are slidably connected to the adjusting rod. In this embodiment, three paddles 721 are preferably used, and the position of the paddle 721 on the adjusting rod is adjusted to make the paddle 721 located above the unloading channel, and the paddle 721 is close to between the unloading channel and the transmission channel 21; a connecting block 741 is slidably connected to the connecting bracket 74, and a guide rod extends from the connecting block 741, and the guide rod is parallel to the unloading channel, and there is a certain distance between the guide rod and the unloading channel. In this embodiment, the guide rod is preferably arc-shaped, so that the arc-shaped guide rod can fit the arc-shaped inner wall of the OK unloading box 71.

[0052] When the main shaft 3 rotates 180°, the raised part of the second cam 33 contacts the fourth roller, and the fourth roller pushes the second slider 72, the adjusting rod and the paddle 721 to rise in turn, and the pushing mechanism 4 pushes the RFID tag with an OK detection result to between the feeding channel and the transmission channel 21. After the main shaft 3 rotates another 180°, the fourth roller loses the contact with the raised part of the second cam 33, and the second slider 72 slides down on the second slide rail, and the second slider 72 drives the adjusting rod and the paddle 721 to descend, and the paddle 721 pokes the RFID tag into the feeding channel.

[0053] The utility model provides an RFID tag reading and writing device with a sorting function. The RFID tag is placed in a transmission channel through an external feeding mechanism. The rotation of the main shaft drives the pushing mechanism to reciprocate. The pushing mechanism reciprocates in the transmission channel to push the RFID tag to move step by step from one end of the transmission channel to the other end of the transmission channel. In the process of the movement of the RFID tag, the RFID tag will first move to the top of the reading and writing component. After the reading and writing component writes the EPC code into the RFID tag, the reading and writing component reads whether the EPC code in the RFID tag is complete to determine whether the RFID tag is NG or OK. When the RFID tag moves to the top of the NG unloading port and the RFID tag is determined to be NG, the air blowing pipe blows the RFID tag below to fall into the NG unloading port. When the RFID tag moves to the top of the NG unloading port and the RFID tag is determined to be OK, the air blowing pipe stops running, and the pushing mechanism continues to push the RFID tag into the OK unloading mechanism. In this way, the RFID tag can be automatically read, written and detected, and the RFID tag with the detection results of NG and OK can be sorted.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
