Description

Technical Field

[0001] This utility model relates to the technical field of RFID tag testing devices, and in particular to an RFID tag bending and pressure resistance testing device. Background Technology

[0002] After processing, RFID tags are mostly arranged on a rolled substrate. They then need to pass through laminating equipment when laminating fabrics and linings. During this process, the RFID tag's chip may be damaged by bending and pressure as it passes through the guide rollers and pressure rollers. There is also a risk of poor contact between the chip's bump pins and the antenna foil, rendering the RFID tag unreadable and reducing the product yield. Therefore, RFID tags typically undergo sampling tests for bending and pressure resistance before leaving the factory, and only those meeting certain bending and pressure resistance performance indicators are shipped.

[0003] Chinese utility model patent CN220893968U discloses an electronic tag bending resistance testing machine, including a mounting frame, a motor, a feeding roller for feeding tags along the tag movement direction, a bending roller group for bending tags, a detection mechanism for detecting tags, and a receiving roller for collecting tags. The detection mechanism consists of a width measuring component for measuring tag width, a support component for supporting the width measuring component, and an adjustment component. The width measuring component consists of scale lines on a support base and indicator blocks that slide along the scale lines. This machine can measure the width of the electronic tag simultaneously with the reader's signal detection after bending, using a detection camera in conjunction with the measuring component, providing more comprehensive detection parameters.

[0004] However, the aforementioned testing machine is only suitable for testing the performance of electronic tags after a single bend, and is inconvenient for tracking and testing the performance of tags after multiple bends, and cannot simultaneously test the pressure resistance of tags. Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution described below arose from this background.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0035] Figure 1 This is a schematic diagram of the structure of this utility model.

[0036] Figure 2 yes Figure 1 A sectional view along line AA. Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0038] See Figure 1 and Figure 2 The figure shows an RFID tag bending and pressure resistance testing device, including a cabinet 100, a power roller mechanism 200, a photoelectric sensor 300, a reader 400, a pressure roller group mechanism 500, a winding roller group mechanism 600, and a PLC controller (not shown in the figure).

[0039] The cabinet 100 serves as the carrier of the entire device, and its bottom is equipped with several casters 110 at intervals to improve the overall flexibility.

[0040] The power roller mechanism 200 is housed within the cabinet 100 and connected to the PLC controller. It provides propulsion power for the label roll. Specifically, the power roller mechanism 200 includes a power roller 210 and a power motor (not shown in the figure). The shaft of the power roller 210 is located within the cabinet 100, and the power motor is located within the cabinet 100 and connected to the power roller 210 and the PLC controller. The power motor drives the power roller 210 to rotate under the control of the PLC controller.

[0041] A photoelectric sensor 300 is installed inside the cabinet 100 and located behind the power roller mechanism 200 along the roll material travel direction, and is connected to the PLC controller. It is used to determine the accurate position of the RFID tags on the tag roll 10. The photoelectric sensor 300 can select the gap between tags or the marking line as a reference to accurately provide the PLC controller with the coordinates of each tag that passes the positioning light point. When the RFID tag just moves into the reading area of ​​the reader 400, the PLC controller controls the pause of the tag roll feeding, so that the reader 400 can read the information of the RFID tag.

[0042] The reader 400 is located inside the cabinet 100, behind the photoelectric sensor 300 along the roll travel direction, and connected to the PLC controller. It is used to read signals from the RFID tags on the tag roll. Each RFID tag on the tag roll 10 is read and its signal is recorded each time it passes through the reader 400's reading area. If an RFID tag is damaged during the winding process, the reader 400 will no longer be able to read signals, and the PLC controller will also record this information. In this way, the PLC controller can not only determine the yield rate of the entire tag roll after testing, but also calculate how many turns of winding occurred for each damaged RFID tag, obtaining more comprehensive and accurate data on the damage status of the tags after bending.

[0043] The pressure roller assembly 500 is located within the cabinet 100 and behind the reader 400 along the roll material travel direction, and is connected to the PLC controller. It is used to apply pressure to the surface of the label roll material 10. Specifically, the pressure roller assembly 500 includes a fixed roller 510, a pressure roller 520, and a pressure roller drive cylinder 530. The fixed roller 510 is located within the cabinet 100, and the pressure roller 520 is located within the cabinet 100 and directly above the fixed roller 510. A compression channel 501 is formed between the pressure roller 520 and the fixed roller 510. The pressure roller drive cylinder 530 is located within the cabinet 100, connected to the pressure roller 520, and connected to the PLC controller. Under the control of the PLC controller, it drives the pressure roller 520 to move vertically up and down, applying a certain pressure to the surface of the label roll material 10 passing through the compression channel 501. The pressure roller 520 can be adjusted to the required pressure according to testing requirements.

[0044] The winding roller assembly 600 is housed within the cabinet 100 and located behind the pressure roller assembly 500 along the roll material travel direction, and is connected to a PLC controller. It is used to guide the winding of the label roll material 10. Specifically, the winding roller assembly 600 includes a first winding roller 610, a second winding roller 620, a third winding roller 630, and a tension drive cylinder 640. The first and second winding rollers 610 and 620 are horizontally spaced within the cabinet 100, meaning their centerlines are on the same horizontal plane. The third winding roller 630 is located within the cabinet 100, below the first and second winding rollers 610 and 620, and its centerline passes through the central axis of the line connecting the centers of the first and second winding rollers 610 and 620. The diameter of the third winding roller 630 is adjustable; different diameters result in different winding angles. The third winding roller 630 can be an air-expanded shaft for adjusting its diameter.

[0045] The tension drive cylinder 640 is located inside the cabinet 100 and connected to the third winding roller 630 and the PLC controller. It drives the third winding roller 630 to move vertically up and down, meaning the position of the third winding roller 630 can be adjusted up and down. When adjusted downwards, it is equivalent to stretching the entire length of the label roll 10, increasing the tension of the label roll 10 during testing, and vice versa. It can be easily adjusted according to the required test tension.

[0046] This utility model also includes a correction roller assembly mechanism 700. The correction roller assembly mechanism 700 is disposed within the cabinet 100 and located between the winding roller assembly mechanism 600 and the power roller mechanism 200, and is connected to a PLC controller. It is used to correct the deviation of the label roll 10, ensuring that the label roll does not deviate in direction during prolonged circular motion. Specifically, the correction roller assembly mechanism 700 includes an offset detection sensor 710, a correction roller assembly 720, and a correction drive motor 730. The offset detection sensor 710 is disposed within the cabinet 100 and connected to the PLC controller; it is used to detect whether the label roll has deviated. The correction roller assembly 720 is located within the cabinet 100 and is used to correct the deviation of the label roll 10. The correction drive motor 730 is disposed within the cabinet 100 and connected to the correction roller assembly 720 and the PLC controller; it is used to drive the correction roller assembly 720 to perform correction. When the offset detection sensor 710 detects that the label roll 10 has deviated, the offset detection sensor 710 sends a correction signal to the PLC controller. The PLC controller controls the correction drive motor 730 to drive the correction roller group 720 to correct the label roll 10 according to the correction signal.

[0047] This utility model also includes a host computer 800, which is installed on the cabinet 100 and connected to the PLC controller. On the one hand, it is used to obtain data transmitted by the PLC controller for display, and on the other hand, it can send control commands to the PLC controller to control the device.

[0048] This utility model also includes an indicator light 900, which is installed on the cabinet 100 and connected to the PLC controller. It is used to display the status of the device, so that users can understand the current status of the device.

[0049] In addition, the cabinet 100 of this utility model is also equipped with multiple guide rollers to change the movement direction of the label roll 10, which can be set according to actual needs.

[0050] The working process of the RFID tag bending and pressure resistance testing device of this utility model is as follows:

[0051] The label roll 10 is joined end to end to form a ring structure and mounted on the testing device. It then passes sequentially through a power roller mechanism 200, a photoelectric sensor 300, a reader 400, a pressure roller assembly 500, a winding roller assembly 600, and a correction roller assembly 700. Driven by the power roller mechanism 200, the label roll 10 moves in a circular motion on the testing device. The required number of winding cycles is pre-set, allowing the label roll to automatically rotate the corresponding number of times on the testing device. After the rotation is complete, the label roll 10 is removed, and the data read by the reader 400 is used to determine the testing status of the label roll 10.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
