AI Technical Summary
In the existing technology, defective products with radio frequency performance below the standard by 3dBm cannot be effectively screened by the testing equipment in the subsequent process, resulting in them flowing to the end customer and causing problems such as abnormal use and time-consuming and labor-intensive manual confirmation.
An aluminum foil shielding layer is pasted into the tag unit whose radio frequency performance is 3dBm lower than the standard. The aluminum foil shielding layer reflects or absorbs electromagnetic waves, ensuring that these tag units show no radio frequency signal in existing detection equipment, and are thus rejected.
This effectively prevents defective products with RF performance below the standard by 3dBm from reaching end customers, avoiding usage abnormalities and manual verification, and saving labor costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electronic tags, and in particular to an Inlay having multiple tag units. Background Technology
[0002] Inlay refers to a semi-finished product where components such as chips and antennas are integrated onto a substrate. It is the core component of smart cards and RFID tags. Inlay factories mainly carry out production processes such as chip bonding, wire winding, surface mounting, spot soldering, and lamination.
[0003] During the inlay process, the factory uses the first defect marking device 9 to mark defective products (those with no RF performance or RF performance below the standard by 3dBm) with black dots (i.e., marking the first defect mark 5 on the PET substrate, which serves as the base layer 1). This facilitates identification and rejection in subsequent processing steps. In other words, the first detection device 7 (Voyantic's Tagsurance 3 series RFID performance testing and encoding equipment, such as the Voyantic Tagsurance3ENS-ML-22465) can detect both products with no RF performance and products with RF performance below the standard by 3dBm during the inlay process. See [link / reference]. Figures 1 to 3 .
[0004] However, due to cost considerations, most manufacturers currently using the second inspection equipment 8 (RFID readers from the Impinj brand, such as the IMPINJ READER IPJ-REV-R220-USA2M) in the downstream processes do not have the function of detecting radio frequency performance below the standard of 3dBm. Therefore, they cannot reject defective products with radio frequency performance below the standard of 3dBm; they only have the function of detecting defective products with no radio frequency performance at all. In other words, the second inspection equipment 8 can only screen out defective products with no radio frequency signal at all. These are then marked by the second defective product marking device 10 (e.g., marking with a second defective label 6) before being rejected. See [link to relevant documentation]. Figures 4 to 6 .
[0005] For example, when the Inlay is used to mount the cardstock (i.e., the first cardstock 12-1 and the second cardstock 12-2 are pasted on both sides of the Inlay to form a label), the cardstock will cover the black dot markings, and the label will not be able to distinguish the original black dots of the Inlay (i.e., the first defect mark 5, see [link]). Figure 5Therefore, some finished products with RF performance 3dBm lower than the standard (because they could not be detected by the second testing device 8 and could not be marked with the second defective label 6 to be rejected) will flow to the end customers. During the use of the products, due to the existence of RF performance 3dBm lower than the standard, there is a probability of incomplete data collection and other abnormalities during inventory or processing by the channel machine. This causes the end customers to spend manpower to cooperate in the inventory and confirmation, which is time-consuming and laborious.
[0006] Therefore, how to eliminate defective products with RF performance below the standard by 3dBm in the Inlay has become a technical problem that needs to be solved. Utility Model Content
[0007] The purpose of this invention is to provide an Inlay with multiple tag units, mainly to solve the problem of how to remove defective products with radio frequency performance lower than the standard by 3dBm in the Inlay.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an Inlay with multiple tag units, the Inlay having multiple tag units includes a substrate layer, and an aluminum foil antenna layer is pasted on one side of the substrate layer to form multiple tag units, characterized in that: among the multiple tag units, there are weak tag units with radio frequency performance lower than the standard 3dBm;
[0009] An aluminum foil shielding layer is pasted on one side of the substrate layer to the part corresponding to the weak target unit, and the aluminum foil antenna layer of the weak target unit is located between the substrate layer and the aluminum foil shielding layer; or an aluminum foil shielding layer is pasted on the other side of the substrate layer to the part corresponding to the weak target unit, and the aluminum foil antenna layer and the aluminum foil shielding layer of the weak target unit are located on two different sides of the substrate layer.
[0010] Furthermore, the vertical projection of the aluminum foil shielding layer overlaps with the vertical projection of the aluminum foil antenna layer.
[0011] In view of the above technical features, the present invention has the following beneficial effects:
[0012] 1. This utility model discloses an inlay with multiple tag units. An aluminum foil shielding layer is pasted on the front or back of the substrate layer 1 corresponding to the weak tag unit. The aluminum foil shielding layer utilizes the principle of reflecting or absorbing electromagnetic waves to eliminate the radio frequency (RF) performance of the inlay antenna. Subsequent manufacturers can use existing testing equipment to reliably screen out tags with absolutely no RF signal and remove them after marking. At this point, weak tag units (i.e., defective products) with RF performance below the standard of 3dBm in the inlay will also be removed.
[0013] 2. In this utility model, an Inlay with multiple tag units is provided, in which the vertical projection of the aluminum foil shielding layer covers the vertical projection of the aluminum foil antenna layer 2, ensuring that the aluminum foil antenna layer of the weak tag unit is fully covered by the aluminum foil shielding layer, and ensuring that the radio frequency performance of the weak tag unit antenna in the Inlay is eliminated by utilizing the principle of electromagnetic wave reflection or absorption of the aluminum foil shielding layer.

[0026] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0027] See Figures 4 to 9 In specific embodiment 1, this embodiment 1 provides an Inlay with multiple tag units. The Inlay with multiple tag units includes a substrate layer 1 (e.g., a PET substrate). An aluminum foil antenna layer 2 is pasted on one side of the substrate layer 1 to form multiple tag units 4-1. Among the multiple tag units 4-1, there are weak tag units 4-2 with radio frequency performance lower than the standard 3dBm, that is, the power of the radio frequency signal of the weak tag unit 4-2 is lower than 2 milliwatts (mW).
[0028] On the other side (i.e., the back) of the substrate layer 1, corresponding to the weak labeling unit 4-2, an aluminum foil shielding layer 3 is pasted. The aluminum foil antenna layer 2 and the aluminum foil shielding layer 3 of the weak labeling unit 4-2 are located on two sides of the substrate layer 1. In other words, a layer of metal aluminum foil (i.e., aluminum foil shielding layer 3) is pasted on the back of the Inlay 4. The principle of electromagnetic wave reflection or absorption by the metal layer is used to eliminate the radio frequency performance of the Inlay 4 antenna. The downstream manufacturer can use existing testing equipment to reliably screen out tags that have no radio frequency signal and mark them (e.g., mark them with the second defective label 6) and then remove them. At this time, the weak labeling unit 4-2 (i.e., defective product) in the Inlay 4 with radio frequency performance lower than the standard by 3dBm will also have no radio frequency signal due to the design of the aluminum foil shielding layer 3 and will also be removed. The downstream manufacturer can effectively prevent the labels with radio frequency performance lower than the standard by 3dBm from flowing to the end customer and causing confusion without increasing equipment investment.
[0029] The vertical projection of the aluminum foil shielding layer 3 covers the vertical projection of the aluminum foil antenna layer 2, that is, the outer size of the aluminum foil shielding layer 3 is greater than or equal to the outer size of the aluminum foil antenna layer 2 in Inlay 4, ensuring that the aluminum foil antenna layer 2 of the weak target element 4-2 is fully covered by the aluminum foil shielding layer 3, and ensuring that the radio frequency performance of the weak target element 4-2 antenna in Inlay 4 is eliminated by using the principle of reflecting or absorbing electromagnetic waves by the aluminum foil shielding layer 3.
[0030] The process flow for the Inlay with multiple tag units in this embodiment 1 is as follows: Figure 7 For a detailed structural diagram, please refer to [link / reference]. Figure 8 and Figure 9 In the Inlay4 factory manufacturing process, the first inspection device 7 can detect both defective products with no RF performance and defective products with RF performance below the standard by 3dBm. See [link / reference]. Figure 7 Then, for defective products with RF performance 3dBm lower than the standard, an aluminum foil shielding layer 3 is added to form the Inlay 4 in this embodiment 1. The structure of the weak standard unit 4-2 in the Inlay 4 is shown in [reference]. Figure 8 and Figure 9 For example, the aluminum foil antenna layer 2 and the aluminum foil shielding layer 3 are respectively pasted on both sides of the substrate layer 1. The aluminum foil shielding layer 3 can be pasted on the back of the substrate layer 1 using an aluminum foil shielding layer pasting device 13 (the aluminum foil shielding layer pasting device 13 can be a fully automatic labeling machine from Novexx, Germany, model XLS204 / XLS206, which is existing technology and will not be discussed further here) or manually. The principle of the aluminum foil shielding layer 3 reflecting or absorbing electromagnetic waves is used to eliminate the radio frequency performance of the weak labeling element 4-2 antenna in Inlay 4. At this time, the weak labeling element 4-2 will also appear as a defective product with no radio frequency performance. Then it enters the subsequent factory process (see...). Figure 4 When Inlay 4 is fitted with mounting paper (i.e., the first paper 12-1 and the second paper 12-2 are pasted on both sides of Inlay 4 respectively) to form a label, after the label unit 4-1 is separated by roller cutting, the first paper 12-1 and the second paper 12-2 are also pasted on both sides of Inlay 4 corresponding to the weak label unit 4-2 where the aluminum foil shielding layer 3 is pasted to form a label. The second detection device 8 screens out the label units 4-1 that have no radio frequency performance at all (including defective products with no radio frequency performance at all and defective products with radio frequency performance lower than the standard 3dBm), and marks them with the second defect mark by the second defect mark marking device 10 (see Figure 5 and Figure 6 ), and then discarded to receiving box 11, see below. Figure 4This ensures that finished products with RF performance below the standard by 3dBm do not reach end customers, that customers will not encounter defective products with RF performance below the standard by 3dBm during use, and that there will be no abnormalities such as incomplete data collection during inventory checks or through-channel processing. This will prevent end customers from having to spend manpower to check and confirm abnormalities, thus saving labor costs.
[0031] See Figures 10 to 11 In specific embodiment 2, this embodiment 2 provides an Inlay with multiple tag units. The difference between this embodiment 2 and embodiment 1 is that: an aluminum foil shielding layer 3 is pasted on one side (i.e., the front) of the substrate layer 1 corresponding to the weak tag unit 4-2. The aluminum foil antenna layer 2 of the weak tag unit 4-2 is located between the substrate layer 1 and the aluminum foil shielding layer 3. That is to say, a layer of metal aluminum foil (i.e., aluminum foil shielding layer 3) is pasted on the front of the Inlay 4. The principle of electromagnetic wave reflection or absorption by the metal layer is used to eliminate the radio frequency performance of the Inlay 4 antenna. The downstream manufacturer can use existing testing equipment to reliably screen out tags that have no radio frequency signal and mark them (e.g., mark the second defective mark 6) and then remove them. At this time, the weak tag unit 4-2 (i.e., defective product) in the Inlay 4 with radio frequency performance lower than the standard by 3dBm will also have no radio frequency signal due to the design of the aluminum foil shielding layer 3 and will also be removed. The downstream manufacturer can effectively prevent the flow of tags with radio frequency performance lower than the standard by 3dBm to the end customer without increasing equipment investment, thus preventing confusion. The processing method of an Inlay with multiple tag units in Embodiment 2 is basically the same as that in Embodiment 1, and will not be repeated here.
