Description

Technical Field

[0001] This utility model relates to the field of RFID UHF reader testing technology, and in particular to a testing device for RFID UHF readers. Background Technology

[0002] RFID readers (short for Radio Frequency Identification), also known as "RFID readers," are wireless radio frequency identification devices. They automatically identify target objects and acquire relevant data through radio frequency identification signals without manual intervention. They can identify high-speed moving objects and simultaneously identify multiple RFID tags, offering quick and convenient operation. RFID readers are available in fixed and handheld types. Handheld RFID readers include low-frequency, high-frequency, ultra-high-frequency, and active types. Many RFID readers undergo performance testing after production. Traditionally, manual testing is used one by one, which is slow and inefficient. When using equipment for testing, because RFID readers have a front and back, they need to be plugged into connectors before testing can begin. For RFID readers placed on conveyor belts, all need to be flipped up so that the front or back is facing up for convenient testing, which is cumbersome. If they are not flipped up, subsequent testing cannot be performed. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a testing device for RFID UHF readers, which solves the problems of the inability to perform efficient and rapid automated testing of RFID UHF readers, and the inability to test whether the reader is facing up or down.

[0004] According to the present invention, a testing device for an RFID UHF reader includes a reader conveyor belt, a front side pushing mechanism, a back side pushing mechanism, a front testing mechanism, and a back testing mechanism.

[0006] The front side-pushing mechanism and the back side-pushing mechanism have the same structure. The front side-pushing mechanism includes a front side-pushing assembly and a front side-shifting conveyor belt. The front side-pushing assembly includes a side-pushing plate, a side-pushing cylinder, a positioning plate, and a positioning plate-pushing cylinder. A first notch for placing the side-pushing plate is provided on one side of the reader conveyor belt, and a second notch is also provided on the corresponding side of the reader conveyor belt. The cylinder shaft of the side-pushing cylinder is located on the back of the side-pushing plate and can push the side-pushing plate from the first notch to the second notch. The first notch and... The second notch has a positioning plate on the side away from the input end of the reader conveyor belt. Two positioning plate push cylinders are installed on the top edge of the positioning plate. A front side shift conveyor belt is provided on the outer side of the second notch, and a first connecting plate is provided between the front side shift conveyor belt and the second notch. The output end of the front side shift conveyor belt extends into the front testing mechanism. The reverse side push mechanism is set on the reader conveyor belt at a distance behind the front side push mechanism. The output end of the reverse side shift conveyor belt on the reverse side push mechanism extends into the reverse testing mechanism.

[0007] The front and back testing mechanisms differ only in the structure of the test plug connecting the reader / writer; all other structures are identical. The front testing mechanism includes a test box, a test box lifting device, an ultra-high frequency (UHF) generator board, and a reader / writer pushing assembly. The front-side conveyor belt transports the reader / writer to the output end and then pushes it onto a temporary plate. The reader / writer pushing assembly pushes the reader / writer into the test box to complete the docking and start the reader / writer's operation. The UHF generator board is located vertically downwards on one side of the test box. The test box lifting device slowly lowers the test box, causing the reader / writer to move vertically downwards from beside the UHF generator board. After moving the test box to the bottom, the test box lifting device pushes the reader / writer onto the test completion and exit conveyor belt. UHF generators are evenly spaced on the UHF generator board.

[0008] In some embodiments of this utility model, side guards are also provided on both sides of the upper surface of the front and back side conveyor belts.

A strip hole is provided at the bottom of the square notch, and a reader / writer pushing component is provided at the bottom of the test box. The output end of the temporary plate is connected to the edge of the square notch.

[0010] In some other embodiments of this utility model, the reader / writer pushing assembly includes a servo motor, a push screw, two limiting slide rods, a moving block, an upward push cylinder assembly, and a push plate. The two ends of the push screw are rotatably mounted, and the servo motor shaft is connected to one end of the push screw.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Reference Figure 1-4 A testing device for an RFID UHF reader includes a reader conveyor belt 1, a front side push mechanism, a back side push mechanism, a front testing mechanism 7, and a back testing mechanism 8.

[0024] The upper surface of the reader conveyor belt 1 is symmetrically provided with side guards 11 on both sides. The reader conveyor belt 1 is provided with a scanner 2 above the input end. The scanner 2 is used to scan the graphics or shapes on the upward side and compare them with the database to identify whether the RFID UHF reader is facing up or down. After identification, the system automatically transports the scanned RFID UHF reader to the corresponding front side push mechanism or back side push mechanism, so that it is transported into the front test mechanism 7 or the back test mechanism 8.

[0025] The front side-pushing mechanism has the same structure as the back side-pushing mechanism. The front side-pushing mechanism includes a front side-pushing assembly and a front side-shifting conveyor belt 5. The front side-pushing assembly includes a side-pushing plate 31, a side-pushing cylinder 3, a positioning plate 41, and a positioning plate downward-pushing cylinder 4. A first notch for placing the side-pushing plate 31 is opened on one side of the reader conveyor belt 1, and a second notch is also provided on the corresponding side-pushing plate 11 on the other side of the reader conveyor belt 1. The cylinder shaft of the side-pushing cylinder 3 is located on the back of the side-pushing plate 31 and can push the side-pushing plate 31 from the first notch to the second notch. The notch and the second notch are provided with a positioning plate 41 on the side away from the input end of the reader conveyor belt 1. Two positioning plate push cylinders 4 are installed on the top edge of the positioning plate 41. The second notch is provided with a front side shift conveyor belt 5 facing outward, and a first connecting plate 60 is provided between the front side shift conveyor belt 5 and the second notch. The output end of the front side shift conveyor belt 5 extends into the front test mechanism 7. The reverse side push mechanism is set at a distance behind the front side push mechanism on the reader conveyor belt 1. The output end of the reverse side shift conveyor belt 6 on the reverse side push mechanism extends into the reverse test mechanism 8.

[0026] When the RFID UHF reader with its front facing up reaches the position of the front side push assembly, the positioning plate 41 is pushed down in advance by the positioning plate push cylinder 4 to prevent the RFID UHF reader from continuing to move sideways. Then, the side push cylinder 3 is used to push out the side push plate 31 in time, thereby pushing the RFID UHF reader out of the second notch and along the first connecting plate 60 to the front side movement conveyor belt 5 until it is transported into the front test mechanism 7 for testing. Similarly, the process of the RFID UHF reader with its back facing up entering the back side push mechanism is the same as that of the front side push mechanism.

[0027] The front testing mechanism 7 and the back testing mechanism 8 differ only in the structure of the test plug 723 connecting the reader / writer; all other structures are identical. The front testing mechanism 7 includes a test box 72, a test box lifting device 74, an ultra-high frequency generating plate 75, and a reader / writer pushing assembly. The front-side conveyor belt transports the reader / writer to the output end and then pushes it onto a temporary plate. The reader / writer pushing assembly pushes the reader / writer into the test box 72 to complete the docking and start the reader / writer's operation. The ultra-high frequency generating plate 75 is located vertically downward on one side of the test box 72. The test box lifting device 74 slowly moves the test box 72 downward, causing the reader / writer to move vertically downward from beside the ultra-high frequency generating plate 75. After the test box is moved to the bottom, the test box lifting device 74 pushes the reader / writer onto the test completion and exit conveyor belt 9. Ultra-high frequency generators 751 are evenly spaced on the ultra-high frequency generating plate 75.

[0028] When the RFID UHF reader is transported to the position next to the test box 72, the reader push-in component pushes the RFID UHF reader into the test box 72 to complete the docking and start the test. During the test, the test box 72 is lowered by the test box lifting device 74. The test box 72 moves downward along the side of the UHF generation plate 75. Since the UHF generation plate 75 generates changing UHF frequency waves, the performance of the RFID UHF reader is determined by comparing the test structure with the actual value. After the test is completed, the reader is pushed out onto the test completion conveyor belt 9.

[0029] Side guards 11 are also provided on both sides of the upper surface of the front lateral conveyor belt 5 and the back lateral conveyor belt 6. This prevents the RFID UHF reader from being mispositioned or detached from the conveyor belt during transportation.

[0030] The test box 72 has a square notch, and a guide limiting plate 721 is symmetrically arranged inside the square notch. A test plug 723 is provided on the inner side wall of the square notch. An ejection component is provided on the side wall above the test plug 723. A strip hole 722 is provided at the bottom of the square notch. A reader push component 73 is provided at the bottom of the test box 72. The output end of the temporary plate is connected to the edge of the square notch.

[0031] When the RFID UHF reader is pushed into the square notch and enters between the two guide limit plates 721, the tail end of the RFID UHF reader is already on the strip hole 722. At this time, the reader push component 73 pushes the RFID UHF reader further inward and connects it to the test plug 723 to start the test. During the test, the test box 72 moves down and passes through multiple UHF generators 751 to generate different UHF bands for testing.

[0032] The reader / writer push assembly 73 includes a servo motor, a push screw 732, two limiting slide rods 733, a moving block 731, a set of upward push cylinders 734, and a push plate 735. The push screw 732 is rotatably mounted at both ends, and the servo motor shaft is connected to one end of the push screw 732. The two limiting slide rods 733 are symmetrically arranged on both sides of the push screw and both ends are fixed. The moving block 731 is movably sleeved on the two limiting slide rods 733 at both ends, and the push screw 732 spirally passes through the middle of the moving block. Two upward push cylinders 734 are embedded in the upper surface of the moving block 731, and a push plate 735 is mounted on the cylinder shaft of the upward push cylinders 734. The push plate 735 is inserted into the strip hole 722.

[0033] When the RFID UHF reader is pushed in for docking, the push cylinder 734 pushes the push plate 735 out of the slot 722 and then moves it inward to abut the rear side of the RFID UHF reader. By pushing the lead screw 732 to pull the moving block 731, the push plate 735 is pulled, so that the RFID UHF reader docks with the test plug.

[0034] The ejection assembly includes an ejection plate 724 and an ejection cylinder. The ejection cylinder is embedded in the side wall inside the test box, and the ejection plate 724 is mounted on the cylinder shaft of the ejection cylinder.

[0035] After the test is completed, the ejector plate 724 is ejected using the ejector cylinder to disconnect the RFID UHF reader from the docking test plug, and then the reader push component 73 is used to push the RFID UHF reader out of the test box in the opposite direction.

[0036] The test box 72 has sliding rod holes at both ends near the rear side wall and a lead screw hole in the middle. The sliding rod holes are fitted onto two vertical limiting rods, and the lead screw hole is fitted onto a vertically positioned downward lead screw, which is driven by a servo motor. The principle of the test box 72's up-and-down movement is the same as that of the reader / writer push assembly 73.

[0037] The reader push-in assembly includes a lateral shifting device 71 and a downward-facing cylinder 711, the tail end of which is installed inside the lateral shifting device 71.

[0038] The lateral displacement device 71 has a structure similar to the test box lifting device 74, one placed horizontally and the other vertically. Its principle is similar to that of the reader / writer push assembly 73. The tail end of the downward-facing cylinder 711 is fitted onto a lead screw, with limiting slide rods on both sides restricting its movement. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on its technical solution and inventive concept, should be included within the scope of protection of this utility model.
