Description

Technical Field

[0001] The present invention relates to the technical field of signal detection equipment, and particularly to a ceramic antenna performance detection device. Background Art

[0002] An RFID electronic tag system generally consists of an electronic tag, an antenna, a reader / writer, and a computer network.

[0003] For example, in the medical industry, in order to facilitate the management of the warehousing, statistics, etc. of a batch of medicine bottles, an RFID electronic tag system has currently been used to automatically read the electronic tag information on the medicine to improve work efficiency.

[0004] Since the RFID electronic tag system is generally for indoor applications, a short-range antenna such as a ceramic antenna is generally selected.

[0005] The reading distance of a ceramic antenna can generally reach 2 meters. Because its reading distance is relatively short, it is also called a short-range antenna. It is an industrial-grade product for indoor use, with a ceramic shell, and has the capabilities of anti-interference, anti-lightning, waterproof and dustproof. It is commonly used for reading RFID electronic tag information.

[0006] When a ceramic antenna reads an RFID electronic tag, the distances between the antenna and the RFID electronic tag in the X, Y, and Z directions will all affect the performance of the antenna and thus affect the reading result of the RFID electronic tag data.

[0007] However, in the prior art, the setting of the distance between the ceramic antenna in the RFID electronic tag system and the electronic tag on the item to be read is generally based on experience, and there is no precise detection device to determine the optimal X, Y, and Z values between the ceramic antenna and the RFID electronic tag for guiding the actual application scenarios. Therefore, there are phenomena of poor antenna performance and unsatisfactory data reading effects.

[0008] Therefore, the prior art still needs to be improved. Summary of the Invention

Detailed implementation manners

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0054] In the present invention, unless otherwise clearly specified or limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0056] Please refer to Figures  1 to 6 , the present invention provides a ceramic antenna performance detection device 100, which includes a base 1, and further includes an antenna driving mechanism 2 arranged on the base 1, a ceramic antenna seat 3 that is in transmission connection with the antenna driving mechanism 2 and reciprocates in the X direction under the action of the antenna driving mechanism 2, and an electronic tag adjusting mechanism 4 installed on the base 1. A slide rail 11 is arranged on the base 1 so that the ceramic antenna seat 3 can move on the base [1].

[0057] At least one row of tag group positions 5 is arranged on the electronic tag adjusting mechanism 4. Each row of tag group positions 5 includes a positioning tag placement position 53 and a test item placement position 54 that are spaced apart in the X direction. The positioning tag placement position 53 is used to place a positioning electronic tag 6, and the test item placement position 54 is used to place an item 8 with a to-be-detected electronic tag 7. In an embodiment of the present invention, the item 8 with the to-be-detected electronic tag 7 is a medicine bottle to detect the accuracy of the ceramic antenna in reading the electronic tag data on the medicine bottle. The positioning electronic tag 6 and the to-be-detected electronic tag 7 in the embodiment of the present invention both adopt RFID electronic tags.

[0058] At least one ceramic antenna 31 is installed on the ceramic antenna seat 3, and a PCB board 32 is electrically connected to the ceramic antenna 31. The positioning electronic tag 6 and the to-be-detected electronic tag 7 within the same row of tag group positions 5 have the same Y and Z values relative to the same ceramic antenna 31. In this way, when using the positioning electronic tag 6 for Y and Z value positioning, the Y and Z values of the to-be-detected electronic tag 7 in the same row are also determined simultaneously. The PCB board 32 can read the data of the positioning electronic tag 6 and the to-be-detected electronic tag 7 through the ceramic antenna 31 and transmit the data to the upper computer for recording.

[0059] The electronic tag adjusting mechanism 4 adjusts and positions the Y and Z values of the distance between the electronic tag 6 and the ceramic antenna 31 to obtain the optimal Y and Z values for the performance of the ceramic antenna 31. Under the condition of these optimal Y and Z values, the antenna driving mechanism 4 drives the ceramic antenna 31 to move in the X direction to read the data of the electronic tag 7 to be detected on the item 8.

[0060] Preferably, a ceramic antenna base positioning block 9 is further provided on the base 1 of the embodiment of the present invention for clamping or loosening the ceramic antenna base 3. Before testing the optimal Y and Z values of the ceramic antenna 31 and the positioning electronic tag 6, it is necessary to fix the ceramic antenna 31 on the ceramic antenna base 3 below the positioning electronic tag 6 and directly opposite to the positioning electronic tag 6. The ceramic antenna base positioning block 9 can quickly fix the positioned and aligned ceramic antenna base 3 on the base 1 to prevent loosening during the detection process.

[0061] The electronic tag adjusting mechanism 4 of the embodiment of the present invention can be manually adjusted or automatically adjusted, and is used to determine the optimal Y and Z values of the positioning electronic tag 6 and the ceramic antenna 31 on the ceramic antenna base 3. The optimal Y and Z values mean that when the distances between the ceramic antenna 31 and the electronic tag 6 in the Y direction and the Z direction are Y and Z respectively, the performance of the ceramic antenna reaches the best, that is, the parameters such as the frequency point, gain, and impedance of the ceramic antenna 31 reach the best, and at this time, the accuracy of reading data is the highest.

[0062] In the embodiment of the present invention, the positioning tag placement positions 53 and the test item placement positions 54 arranged in a row in the X direction form a row of tag group positions 5. The positioning tag placement positions 53 are used to place the positioning electronic tags 6, and the test item placement positions 54 are used to place the items 8 to be detected, such as medicine bottles, and the electronic tag 7 to be detected is placed at the bottom of the medicine bottle. The positioning electronic tag 6 is used to debug and determine the optimal Y and Z distance values between the positioning electronic tag 6 and the ceramic antenna 31. After determining the Y and Z distance values, the electronic tag 7 to be detected is used to detect the specific item 8 to verify the accuracy of the ceramic antenna 31 reading the data of the electronic tag 7 to be detected on the specific item 8 under the condition of these Y and Z values.

[0063] The tag group position 5 of the present invention can be set in one row or multiple rows according to requirements. As Figure 3 shown, in the embodiment of the present invention, the tag group position 5 is set in multiple rows, that is, each row of tag group positions 5 includes the positioning tag placement position 53 and the test item placement position 54. The positioning electronic tags 6 and the electronic tags 7 to be detected are placed on each row of tag group positions 5, and the positioning electronic tags 6 in each row only detect and position the optimal Y and Z values of this row.

[0064] The setting of multiple rows of tag group positions 5 enables the detection device 100 of the present invention to simultaneously perform experimental detections on multiple rows of electronic tags.

[0065] Preferably, in one row of tag group positions 5, a plurality of test item placement positions 54 may be provided along the X direction for batch testing.

[0066] The working principle of the ceramic antenna performance testing device 100 of the present invention is as follows:

[0067] As Figure 7 shown, first place the ceramic antenna base 3 at position A on the base 1, and then move the ceramic antenna base 3 along the X direction closer to the positioning electronic tag 6 on the electronic tag adjusting mechanism 4 until it reaches position B in the figure. At this time, the positioning electronic tag 6 of the electronic tag adjusting mechanism 4 is directly opposite the ceramic antenna 31 below it along the Z direction, then the positioning of the ceramic antenna base 3 is completed, and then use the ceramic antenna base positioning block 9 to clamp and fix the ceramic antenna base 3 on the base 1.

[0068] Then use the electronic tag adjusting mechanism 4 to move the positioning electronic tag 6 on each row of tag group positions 5 in the Y and Z directions. The ceramic antenna 31 obtains the signal on the positioning electronic tag 6 and uploads it to the host computer through the PCB board 32 to observe the performance indicators of the ceramic antenna 31 in real time when the Y and Z values change until the best performance data is obtained, and record the Y and Z values at this time of the best performance data as the best Y and Z values.

[0069] Because the to-be-tested electronic tag 7 also moves along, and the same to-be-tested electronic tag 7 and the positioning electronic tag 6 have the same Y and Z values relative to the same ceramic antenna 31. In this way, by adjusting and determining the best Y and Z values of the positioning electronic tag 6, the best Y and Z values of the to-be-tested electronic tags 7 in the same row are also adjusted and determined.

[0070] After obtaining the best Y and Z values, loosen the ceramic antenna base positioning block 9 to make the ceramic antenna base 3 recover its function of sliding along the X direction on the base 1, and then activate the antenna driving mechanism 2 to drive the ceramic antenna base 3 to move repeatedly between positions C and D on the base 1 along the X direction, and at the same time read the data information of the to-be-tested electronic tag 7 on the item 8 such as the medicine bottle in this embodiment to verify the accuracy of the ceramic antenna 31 actually reading the medicine bottle information at this best Y and Z value. During the movement in the X direction, the X value when the signal is the best can be obtained.

[0071] As can be seen from the above, the ceramic antenna performance testing device 100 of the present invention can accurately detect the best XYZ distance between the ceramic antenna 31 and the electronic tag, so that the ceramic antenna 31 can achieve the best performance in actual applications to ensure the accuracy, stability, etc. of data reading.

[0072] Specifically, as Figure 3 and Figure 4As shown, in the embodiment of the present invention, multiple rows of tag group positions 5 are arranged in parallel along the Y direction on the electronic tag adjusting mechanism 4, and each row of tag group positions 5 includes a positioning tag placement position 53 and multiple test item placement positions 54.

[0073] Multiple ceramic antennas 31 are installed along the Y direction on the ceramic antenna base 3 and are respectively matched with multiple rows of tag group positions 5. Each ceramic antenna 31 reads the data of the positioning electronic tag 6 and the to-be-detected electronic tag 7 within the corresponding row of tag group positions 5.

[0074] The arrangement of multiple rows of tag group positions 5 and multiple ceramic antennas 31 can improve the detection efficiency of the detection device 100, and can detect the optimal Y and Z values of multiple ceramic antennas 31.

[0075] Further, as Figure 3 shown, the multiple rows of tag group positions 5 on the electronic tag adjusting mechanism 4 are divided into vertical tag group positions 51 for vertically placing the positioning electronic tag 6 and the to-be-detected electronic tag 7, and inclined tag group positions 52 for obliquely placing the positioning electronic tag 6 and the to-be-detected electronic tag 7.

[0076] Correspondingly, horizontal ceramic antennas 31 and inclined ceramic antennas 31 are provided on the antenna mounting block 3 and are respectively opposite to the vertical tag group positions 51 and the inclined tag group positions 52.

[0077] That is, the tag group positions 5 of the present invention are divided into two types. One is the vertical tag group position 51 for vertically placing a row of positioning electronic tag 6 and the to-be-detected electronic tag 7, and the other is the inclined tag group position 52 for obliquely placing a row of positioning electronic tag 6 and the to-be-detected electronic tag 7. Each row of vertical tag group positions 51 also includes a positioning tag placement position 53 and test item placement positions 54 arranged at intervals along the X direction. Each inclined tag group position 52 also includes a positioning tag placement position 53 and test item placement positions 54 arranged at intervals along the X direction.

[0078] The arrangement of the vertical tag group positions 51 and the inclined tag group positions 52 can meet the detection needs of ceramic antennas 31 set at different angles and improve the detection ability of the detection device 100 of the present invention.

[0079] As Figure 4 shown, the electronic tag adjusting mechanism 4 of the present invention includes a first adjusting mechanism 41 vertically installed on the base 1 and a second adjusting mechanism 42 obliquely installed on the base.

[0080] At least one row of the vertical tag group positions 51 is provided on the first adjusting mechanism 41, and the vertical tag group positions 51 are driven to move in the Y1 and Z1 directions relative to the horizontally placed ceramic antennas 31.

[0081] At least one row of the diagonal label group positions 52 is provided on the second adjusting mechanism 42, driving the diagonal label group positions 52 to move in the Y2 and Z2 directions relative to the diagonally placed ceramic antenna 31.

[0082] The first adjusting mechanism 41 and the second adjusting mechanism 42 respectively adjust the vertical label group positions 51 and the diagonal label group positions 52 to meet the multi-angle adjustment requirements of the horizontal and diagonal directions of the ceramic antenna 31.

[0083] Specifically, as Figure 4 and Figure 5 shown, the first adjusting mechanism 41 includes a Y1-direction fixed seat 411 installed on the base 1, a Y1-direction slider 412 installed on the Y1-direction fixed seat 411, and the first mounting surface 4121 of the Y1-direction fixed seat 411 and the Y1-direction slider 412 is parallel to the plane of the base 1.

[0084] It further includes a Y1-direction knob 413 for driving the Y1-direction slider 412 to slide in the Y1 direction.

[0085] It further includes a Z1-direction fixed seat 414 vertically installed on the Y1-direction slider 412, a Z1-direction slider 415 installed on the Z1-direction fixed seat 414, and a Z1-direction knob 416 for driving the Z1-direction slider 415 to slide in the Z1 direction.

[0086] A first cantilever 417 extends from the Z-direction slider, and the other end of the first cantilever 417 is installed with a first positioning label mounting bracket 418, and a first item mounting bracket 419 is installed in the middle of the first cantilever 417.

[0087] A plurality of first positioning label mounting cylinders 4181 are arranged along the Y direction on the first positioning label mounting bracket 418, and multiple rows of first item placement grooves 4191 are arranged along the Y direction on the first item mounting bracket 419. The first positioning label mounting cylinders 4181 and the first item placement grooves 4191 in the same row in the X direction form a row of vertical label group positions 51.

[0088] In this example, the Y1-direction fixed seat 411 and the Y1-direction slider 412, and the Z1-direction fixed seat 414 and the Z1-direction slider 415 all adopt a dovetail groove structure for cooperation.

[0089] The first positioning label mounting cylinders 4181 in this embodiment are equivalent to the positioning label placement positions 53, and the first item placement grooves 4191 are equivalent to the test item placement positions 54. A positioning electronic label 6 is provided at the bottom of the first positioning label mounting cylinder 4181, and an item 8 is placed in the first item placement groove 4191. In this embodiment, the item 8 is a medicine bottle, and a to-be-detected electronic label 7 is provided at the bottom of the medicine bottle.

[0090] In this embodiment, there are 3 first positioning label mounting cylinders 4181 arranged along the Y direction, and 3 rows of first item placement slots 4191 arranged along the Y direction, that is, there are 3 rows of vertical label groups 51 on the first adjustment mechanism 41 of this embodiment.

[0091] Please refer to Figures 4 to 6 , the second adjustment mechanism 42 includes a Y2-direction fixing seat 421 mounted on the base 1, a Y2-direction slider 422 mounted on the Y2-direction fixing seat 412, and the mounting surface 4211 of the Y2-direction fixing seat 421 and the Y2-direction slider 422 forms an oblique angle with the plane of the base 1. The size of the angle in the embodiment of the present invention can be set according to actual needs.

[0092] It further includes a Y2-direction knob 423 for driving the Y2-direction slider 422 to slide in the Y2 direction.

[0093] It further includes a Z2-direction fixing seat 424 vertically mounted on the Y2-direction slider 422, a Z2-direction slider 425 mounted on the Z2-direction fixing seat 424, and a Z2-direction knob 426 for driving the Z2-direction slider 425 to slide in the Z2 direction.

[0094] A second cantilever 427 extends from the Z2-direction slider 425, a second positioning label mounting bracket 428 is mounted at the other end of the second cantilever 427, and a second item mounting bracket 429 is mounted in the middle of the second cantilever 427.

[0095] There are multiple second positioning label mounting cylinders 4281 arranged along the Y direction on the second positioning label mounting bracket 428, and multiple rows of second item placement slots 4291 arranged along the Y direction on the second item mounting bracket 429. The second positioning label mounting cylinders 4281 and the second item placement slots 4291 in one row in the X direction form an inclined label group position 52.

[0096] The Y2-direction fixing seat 421 and the Y2-direction slider 422, and the Z2-direction fixing seat 424 and the Z2-direction slider 425 in this example both adopt a dovetail groove structure for cooperation.
