Description

Technical Field

[0001] The utility model relates to the technical field of RFID tag testing, in particular to a continuous RFID tag manual inactivation device. Background Art

[0002] RFID tags are mainly applied in the clothing field and are widely used in aspects such as clothing receiving and shipping, rapid inventory in stores, and checkout, greatly improving the operation efficiency of each link. And they also show great capabilities in various industries such as airline luggage, retail, consumer electronics, power, and healthcare.

[0003] In order to facilitate the application in various fields, RFID tags need to be compounded with a bottom material and die-cut into roll tags that can be used individually. During the processing, it is impossible to have 100% qualified products, and there will definitely be defective products. Defective products are marked by inkjet coding during manufacturing.

[0004] When an RFID tag processing factory ships products to customers, it generally promises to ship 100% qualified products. Then, the above-mentioned tags with defective marks need to be replaced during product inspection. Since the tags can be peeled off and used individually, the defective tags are peeled off and replaced with a qualified tag. At the same time, during the inspection process, some products with defective appearance but without tags, such as dirt and scratches, may also be replaced with qualified products by this method.

[0005] With the increasingly wide application of RFID, the forms of RFID tags required by customers are also different. For example, customers need continuous hangtags, ribbon tags, etc. This type of tag cannot be peeled off individually during the processing. Because customers need to code and write on the tags in the subsequent process and then process them into individual tags for use.

[0006] For tags that cannot be peeled off, the conventional method for defective products is to remove the chip by punching at the chip location to ensure that the tag is defective. The reason for doing this is that after customers receive the tags, they need to write code and print information on the machine. If the tag has performance, it can be coded. However, if the tag has problems in appearance or size, or is a tag with weak performance, then it is very likely that the coding and printing of this tag will succeed, but it is a tag that end customers cannot accept, and a qualified tag needs to be found again for coding and printing operations, resulting in a large amount of rework.

[0007] This method is applicable to some materials that can be punched, but for products such as ribbon tags, punching becomes more difficult because the ribbon is soft and a woven product, and it is easy to slip the wire. Summary of the Utility Model

[0008] In view of the above problems, the present utility model provides a continuous RFID tag manual inactivation device that is convenient to operate and saves time.

[0009] The technical solution of the present utility model is as follows: A continuous RFID tag manual inactivation device includes a test box and a control box.

[0024] As shown in the present utility model, Figure 1-2 The working method of the continuous RFID tag manual inactivation device includes the following steps:

[0025] S1. The continuous RFID tag (i.e., the non - peelable continuous RFID tag 10) continuously moves the tape under the inspection of the quality inspection personnel.

[0026] S2. When the quality inspection personnel find defective products with pre - process marks or find appearance and dimension defects (such as dirt on the label surface), stop the movement of the label.

[0027] S3. Hold the inactivation device and move it directly above the target tag.

[0028] S4. Press the trigger button in the inactivation device.

[0029] S5. The inactivation device starts the interrogation work.

[0030] If the label indicator light lights up when the tag is interrogated, continue to the next step.

[0031] If the tag is not interrogated, stop and return to S4.

[0032] S7. Write the Kill password; write the Kill password in the Reserved area of the tag chip;

[0033] Reserved area: The area in the RFID tag chip that stores the operation tag password.

[0034] If successful, proceed to the next step;

[0035] If failed, return to S4;

[0036] S8. Kill the tag; Kill is a standard command in the RFID communication protocol. By sending a Kill command with the Kill password through the reader / writer, after the tag receives the command, it compares the password in the Reserved area. If they match, it makes itself permanently silent.

[0037] If successful, the buzzer sounds and proceed to the next step;

[0038] If failed, return to S4;

[0039] S9. The quality inspection personnel remove the inactivation device and continue with the product inspection.

[0040] In step S3, it is possible to touch the tag or be within 2 cm of the tag.

[0041] During the operation of the present utility model, when the quality inspection personnel find defective products, by placing the test box in the inactivation device directly above the target tag and pressing the trigger button, interrogation and Kill operations are performed to inactivate the defective products, which is convenient and reliable.

[0042] The present utility model first uses a small-sized near-field antenna. The field formed by the antenna itself will not cover multiple tags, only one tag. At the same time, since it is a near-field antenna, a relatively high power can be set without forming a large-range field. In addition, the main control module will notify in the form of light or sound after execution, which is convenient and fast.

[0043] The present utility model first confirms whether the tag has performance through interrogation. If the tag cannot be interrogated, it indicates that the tag does not have RFID performance, and there is no need to perform the Kill operation. If directly performing the Kill operation and it fails, it is impossible to confirm whether it is a problem with the Kill operation itself or the tag itself.

[0044] In step S5, if the tag is not interrogated, repeat the interrogation action (such as setting two or three interrogation actions).

[0045] Repeat the action to ensure the reliability of the interrogation. After repetition, if the tag still cannot be interrogated, it indicates that the tag itself is electrically defective.

[0046] The continuous RFID tag manual inactivation device includes a test box 1 and a control box 2,

[0047] The test box 1 includes a test antenna 4, a trigger button 5, and a prompt device. The test antenna is used to transmit a carrier wave and a test command. The trigger button is used to initiate the Kill operation. The prompt device is used for prompting.

[0048] The control box 2 includes a main control module 8 and a reader / writer module 9. The main control module is connected to the reader / writer module. The reader / writer module is connected to the test antenna. The trigger button and the prompt device are respectively connected to the main control module.

[0049] The present utility model includes three parts: a test box 1, a control box 2, and a connection line 3. Among them, the test box integrates a test antenna (for transmitting a carrier wave and a test command), a trigger button (manually triggering the opening of the Kill operation), an indicator light (prompting that a tag has been queried), and a buzzer (sounding after the tag has been killed).

[0050] The control box integrates an RFID reader / writer (generating a carrier wave and modulating and demodulating data) and a main control module (receiving the trigger, controlling the RFID reader / writer to operate according to the process, and outputting the result).

[0051] The connection line includes a radio frequency line (transmitting RFID radio frequency signals) and a signal line (trigger signal, indicator light, and buzzer signal).

[0052] The prompt device includes an indicator light 6, and the indicator light is used to prompt that a tag has been queried.

[0053] The prompt device further includes a buzzer 7, and the buzzer is used to prompt that the tag has been killed.

[0054] The main control module is a single-chip microcomputer or a PLC, which can be selected according to the actual working conditions.

[0055] The reader / writer module is an RS500 module of Impinj, which can be selected according to the actual working conditions.

[0056] The present utility model facilitates the manual inactivation of defective products and can operate on a single tag. It uses a near-field antenna and can set a relatively high power (>20 dBm), and can also Kill weak tags. It integrates the Kill process and has a one-key operation. The operation has light or sound prompts for the result and status of the operation.

[0057] In the present utility model, Kill means inactivation.
