Description

Technical Field

[0001] This utility model relates to the field of label measurement technology, and in particular to a label reading distance measuring device. Background Technology

[0002] Tag reading distance measurement refers to measuring the reading distance of an RFID tag under specific conditions, which is one of the important indicators for evaluating the performance of an RFID system. When measuring tag reading distance, the tag is held vertically with a background plate placed at its rear. An automatic distance sensor is used to measure the tag's distance.

[0003] Currently, label distance measurement typically uses a handheld background board. However, this method has several drawbacks. It requires multiple people to work together, increasing labor and communication costs. Furthermore, manually holding the background board makes it difficult to ensure measurement stability and consistency, leading to poor data accuracy. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a tag distance measuring device that can reduce labor costs during operation and better ensure the accuracy of measurement data.

[0005] This utility model proposes a label reading distance measuring device, including a measuring box, several background plates, a snap-fit ​​assembly, and a label fixing platform. The label fixing platform is located at the front end of the measuring box and has a positioning groove for label positioning and installation. Several snap-fit ​​grooves are formed on the side surface of the measuring box. Each background plate is made of a different material and is snap-fitted into each snap-fit ​​groove. The snap-fit ​​assembly includes a spring and a snap-fit ​​block. Each snap-fit ​​groove has a receiving groove on its bottom wall. The spring is placed in the receiving groove, and the snap-fit ​​block extends into the snap-fit ​​groove under the action of the spring. The end of the snap-fit ​​block facing the outside of the measuring box is set as an inclined surface. A limiting groove is formed on the bottom of each background plate near the end wall of the snap-fit ​​groove, and the snap-fit ​​block can be snapped into the limiting groove at the bottom of the background plate.

[0006] Preferably, the measuring device is provided with eight background plates, and the materials of each background plate are metal, acrylic, glass, hollow board, wood, ceramic, plastic and foam, respectively.

[0007] Preferably, the measuring box has a cuboid structure.

[0008] Preferably, the bottom of the measuring box is provided with four anti-slip support feet.

[0009] Preferably, each of the anti-slip support feet is provided with a screw at its top end. The screw is threaded to the bottom of the measuring box, and the length of the screw outside the measuring box is set to "L" and satisfies 0cm. <L<3cm。

[0010] Preferably, the length of the background plate is set to "W", and the distance between the snap-fit ​​block and the end wall of the snap-fit ​​groove is set to "M", satisfying M=W.

[0011] Preferably, the measuring box is made of aluminum alloy.

[0012] Preferably, a lifting rod is fixedly provided on one side of each of the background plates.

[0013] Preferably, each of the background panels has a material label on one side.

[0014] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0015] 1. Each background plate of the label reading distance measuring device is mounted in the slot of the test box by sliding clips. When measuring the label reading distance with this measuring device, there is no need for manual handling of the background plate. The operation does not require the cooperation of multiple people, reducing labor costs. Moreover, the stability and consistency of the measurement are guaranteed during the measurement process, thereby ensuring the accuracy of the measurement data.

[0016] 2. Install each background plate into its respective slot in the measuring box. When the background plate is not in use, it can be directly hidden in the slot and the locking block limits its position to prevent it from sliding out of the slot, thus protecting it. When the background plate is in the measuring state, it partially slides out of the slot, and the locking block, under the action of the spring, locks into the limiting groove at the bottom of the background plate, thus ensuring that the background plate remains in a stable position with the measuring box.

[0029] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-11 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A label reading distance measuring device includes a measuring box 1, eight background boards 2, and a label fixing platform 3. The measuring box 1 has a rectangular parallelepiped shape, with dimensions of 50cm × 30cm × 40cm. Eight slots 11 are formed on one side of the measuring box 1 for mounting the eight background boards 2. The eight background boards 2 are different materials, namely metal, acrylic, glass, hollow board, wood, ceramic, plastic, and foam. The metal background board 2, acrylic background board 2, glass background board 2, hollow board background board 2, wood background board 2, ceramic background board 2, plastic background board 2, and foam background board 2 are sequentially installed in the slots 11 of the measuring box 1.

[0031] The measuring box 1 is made of aluminum alloy. Aluminum alloy is easy to process and form, making the measuring box 1 convenient for industrial production. Furthermore, the aluminum alloy measuring box 1 not only has the advantage of being lightweight but also has higher strength and rigidity, resulting in better durability. The label fixing platform 3 is located at the front end of the measuring box 1, and a positioning groove 31 is formed on the surface of the label fixing platform 3. When it is necessary to measure the distance of the label 5, the label 5 is vertically inserted into the positioning groove 31 of the label fixing platform 3.

[0032] Reference Figure 4 , Figure 5 and Figure 6 After the background plates 2 are installed into the slots 11 of the measuring box 1, in order to prevent the background plates 2 from detaching from the measuring box 1, a snap-fit ​​assembly 4 is provided near the opening of each slot 11. The snap-fit ​​assembly 4 includes a spring 41 and a snap-fit ​​block 42. Correspondingly, a receiving groove 14 is formed on the bottom wall of each slot 11, and the receiving groove 14 is near the opening of the slot 11. The spring 41 is placed in the receiving groove 14, and the snap-fit ​​block 42 is fixed to one end of the spring 41, so that the snap-fit ​​block 42 passes through the receiving groove 14 into the slot 11 under the action of the spring 41.

[0033] Reference Figure 6 and Figure 7 Each snap-fit ​​block 42 has an inclined surface 421 facing outwards from the measuring box 1. When each background plate 2 is installed into the snap-fit ​​groove 11 of the measuring box 1, the background plate 2 moves along the inclined surface of the snap-fit ​​block 42 into the snap-fit ​​groove 11. This causes the background plate 2 to gradually press down the snap-fit ​​block 42 until the snap-fit ​​block 42 is completely accommodated in the receiving groove 14. The length of each background plate 2 is set as "W", and the distance between the snap-fit ​​block 42 and the end wall of the snap-fit ​​groove 11 is set as "M", satisfying M=W. Thus, when one side of the background plate 2 abuts against the end wall of the snap-fit ​​groove 11, the bottom of the background plate 2 disengages from the snap-fit ​​block 42; at this time, the snap-fit ​​block 42, under the action of the spring 41, extends into the snap-fit ​​groove 11, and one side of the background plate 2 abuts against the snap-fit ​​block 42. Thus, the snap-fit ​​block 42 can limit the background plate 2 located in the snap-fit ​​groove 11, preventing the background plate 2 from moving within the snap-fit ​​groove 11.

[0034] Reference Figure 8 and Figure 9, when using the background plate 2 for label 5 reading distance measurement, in order to prevent the background plate 2 from detaching from the measurement box 1, a limiting groove 21 is formed at the bottom end of each background plate 2 on the side close to the end wall of the clamping groove 11. Before using the background plate 2 for label 5 reading distance measurement, press the clamping block 42 down into the receiving groove 14, and slightly tilt the measurement box 1 so that the background plate 2 slides out of the clamping groove 11 until the clamping block 42 is clamped into the limiting groove 21 at the bottom end of the background plate 2 under the elastic force of the spring 41, thereby preventing the background plate 2 from completely detaching from the measurement box 1.

[0035] Refer to Figure 2 and Figure 10 , in order to facilitate pulling the background plate 2 out of the clamping groove 11 of the measurement box 1, a lifting rod 22 is provided on the outer side of each background plate 2. Thus, when it is necessary to use the background plate 2 for label 5 reading distance measurement, first press the clamping block 42 down into the receiving groove 14, and then hold the lifting rod 22 to pull the measurement plate out of the clamping groove 11 of the measurement box 1 until the clamping block 42 is clamped into the limiting groove 21 at the bottom end of the background plate 2 under the elastic force of the spring 41. Compared with tilting the measurement box 1 to make the background plate 2 slide out of the measurement box 1, pulling the measurement plate out of the clamping groove 11 of the measurement box 1 through the lifting rod 22 can prevent the background plate 2 from quickly sliding out of the clamping groove 11 and detaching from the measurement box 1. Before pulling the background plate 2 out of the clamping groove 11 of the measurement box 1, in order to accurately and conveniently understand the material type of each background plate 2 on the measurement box 1, a material identification 23 is provided on one side of each background plate 2, and the staff can clearly understand the material of the corresponding background plate 2 through the material identification 23 on one side of each background plate 2.

[0036] Refer to Figure 1 and Figure 11 , anti-slip support feet 12 are provided at the bottom end corners of each measurement box 1, and a screw rod 13 is fixedly provided at the top end of each anti-slip support foot 12. Thread the screw rod 13 at the top end of the anti-slip support foot 12 into the top end of the measurement box 1. By rotating the screw rod 13 to change the support height of the measurement box 1, it can adapt to different usage environments. Set the length dimension of the screw rod 13 outside the measurement box 1 as "L", and make the length dimension of the screw rod 13 outside the measurement box 1 satisfy 0 cm < L < 3 cm, so that the anti-slip support feet 12 have a 3 cm adjustment space for the support height of the measurement box 1.

[0037] The specific implementation principle of this application embodiment is as follows: When the label 5 distance measuring device is needed to measure the distance of the label 5, the label 5 distance measuring device is placed in front of the automatic distance measuring sensor, so that the label fixing platform 3 is located between the distance measuring sensor and the background plate 2. The background plates 2 of various materials are sequentially inserted into the respective insertion slots 11 of the measuring box 1. During installation, the bottom end of each background plate 2 abuts against the locking block 42. As each background plate 2 is pushed in, the locking block 42 is pressed down into the receiving groove 14. When one side of each background plate 2 abuts against the end wall of the insertion slot 11, the locking block 42 enters the insertion slot 11 under the action of the spring force 41, so that the background plate 2 is limited between the end wall of the insertion slot 11 and the locking block 42. In this way, the locking block 42 plays a limiting role in the background plate 2, preventing the background plate 2 from sliding out of the insertion slot 11 of the measuring box 1.

[0038] When measuring the distance of label 5, select the appropriate background plate 2 based on the material marking 23 on one side of each background plate 2. Hold the lifting rod 22 on one side of the background plate 2 to pull the background plate 2 outwards towards the insertion slot 11 until the locking block 42 is inserted into the limiting slot 21 at the bottom of the background plate 2 under the action of the spring 41. Vertically insert the label 5 to be measured into the positioning slot 31 of the label fixing platform 3. Select the measurement mode through the touch screen operation interface, adjust the angle of the automatic distance measuring sensor, and click the start measurement button. The automatic distance measuring sensor will automatically collect and process data, and the measurement results will be displayed on the screen in real time. If environmental factors need to be simulated, parameters such as temperature, humidity, and light intensity can be set on the operation interface. Measurement can be performed after the environment stabilizes. Measure the length of label 5 in this way. Finally, rotate label 5 90 degrees and insert it into the positioning slot 31 of the label fixing platform 3 to measure the width of label 5.

[0039] When measuring the distance of label 5 using this label distance measurement device, there is no need to hold the background plate 2 by hand, reducing labor costs. Furthermore, the background plate 2 remains stable during the measurement process, ensuring measurement stability and consistency, resulting in more accurate measurement data. The label distance measurement device also allows for easy switching of the background plate 2, meeting the needs of label distance measurement under different material backgrounds and adapting to diverse label testing scenarios.

[0040] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
