Description

Technical Field

[0001] This invention belongs to the field of RFID technology, specifically relating to an RFID reader and its usage method. Background Technology

[0002] Radio Frequency Identification (RFID) is an abbreviation for Radio Frequency Identification. Its principle is to conduct non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID has a wide range of applications. In hospitals, it is often used for material management. RFID tags are attached to medical equipment, and the information of the equipment is stored in the tag. After identification, it can be quickly determined which department the equipment belongs to. RFID technology can also prevent equipment from outside the hospital from being mixed in, which is very convenient.

[0003] However, when a large number of medical devices need to be identified in batches, scanning them one by one is very time-consuming. When scanning them all at once, due to the structure of the RFID tags, if the tags are not facing the scanning antenna, there is a risk of missed scans (i.e., the tags cannot be identified), which is inconvenient for operators.

[0004] To address the aforementioned issues, this application proposes an RFID reader and its usage method. Summary of the Invention

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] like Figures 1 to 11 As shown;

[0058] This invention relates to an RFID reader, comprising a housing 1 and a display module 2 mounted on the housing 1. A cover plate 3 is rotatably connected to the front end of the housing 1 via a torsion spring. A tray 5 is provided inside the housing 1. A scanning antenna 4 is mounted inside the housing 1 above the tray 5. A flip assembly 600 is installed inside the housing 1. The flip assembly 600 includes a fixing plate 611 fixed to the inner side wall of the housing 1 and a drive motor 612 mounted on the bottom side of the fixing plate 611. A pulley A613 is fixed to the output end of the drive motor 612. A pulley B614 is provided above pulley A613, and a synchronous belt 615 is installed between pulley A613 and pulley B614. A housing mechanism 620 is provided above the fixed plate 611. The housing mechanism 620 includes two side plates 621. A rotating shaft A624 is installed on the outer side wall of the side plate 621. The rotating shaft A624 is rotatably connected to the inner wall of the housing 1. The pulley B614 is sleeved and fixed on the outer side wall of the rotating shaft A624. A connecting plate 622 is fixed on the top side of the side plate 621, and a top plate 623 is fixed on the front side of the side plate 621.

[0059] The top plate 623 has an inlet / outlet 626 at the location corresponding to the cover plate 3. A guide assembly 800 is installed on the bottom side of the top plate 623. The guide assembly 800 includes a bottom plate 801 fixed to the bottom side of the side plate 621 and the top plate 623. Two symmetrically arranged U-shaped rails A802 are fixed on the surface of the bottom plate 801. A U-shaped rail B803 is slidably connected to the inner side of the U-shaped rail A802. A sliding rod 804 is slidably connected to the inner side of the U-shaped rail B803. A moving platform 821 is fixed on the surface of the sliding rod 804. A toothed groove 805 is provided in the middle of the bottom plate 801. A gear 823 is rotatably connected to the bottom side of the moving platform 821 at the location corresponding to the toothed groove 805. A motor 822 is embedded in the moving platform 821 on one side of the gear 823. The motor 822 is connected to the gear 823.

[0060] It should be noted that multiple switches are mounted on the surface of housing 1.

[0061] In this embodiment: When the invention is in use, the motor 822 is started by a switch on the housing 1. The motor 822 drives the gear 823 to rotate, thereby moving the moving platform 821. When the moving platform 821 moves, the sliding rod 804 slides, causing the U-shaped rail B803 to slide. The bottom surface of the moving platform 821 is always in contact with the sliding rod 804, U-shaped rail B803, and U-shaped rail A802 to ensure the stability of the moving platform 821. The moving platform 821 extends out from the inlet / outlet 626, pushing the cover plate 3 downward to flip open. Finally, the moving platform 821 extends outside the housing 1. The operator places the tray 5 on the surface of the moving platform 821 and starts the motor 822 again. The mobile stage 821, carrying the tray 5, is reset and enters the scanning area of ​​the scanning antenna 4. The scanning antenna 4 scans the equipment in the tray 5 and reads the information in the tags. When it is necessary to change the angle of the equipment in the tray 5, the drive motor 612 is started. The drive motor 612 can drive the housing mechanism 620 to rotate via the synchronous belt 615, or it can drive the housing mechanism 620 to shake back and forth, thereby causing the tray 5 to tilt or shake, causing the equipment in the tray 5 to scatter. After the drive motor 612 drives the housing mechanism 620 to reset, the scanning antenna 4 scans again. The scattered equipment increases the probability of the scanning antenna 4 scanning and reading, avoids missed scans, and improves the accuracy of identification.

[0062] Furthermore:

[0063] like Figures 1 to 7 As shown;

[0064] Based on the above:

[0065] To prevent the tray 5 and the instrument from falling off during the flipping motion, a sealing frame 631 is provided inside the housing mechanism 620. An air pump 641 is fixed to the inner side of the connecting plate 622. The output end of the air pump 641 passes through the connecting plate 622 and is connected to a conduit 642 set on the surface of the connecting plate 622. A pneumatic telescopic rod 643 is connected to the end of the conduit 642 away from the air pump 641. There are two sets of pneumatic telescopic rods 643, and the outer walls of the two sets of pneumatic telescopic rods 643 are respectively fixed to the inner surface of the two side plates 621. The output end of the pneumatic telescopic rod 643 is fixed to the surface of the sealing frame 631.

[0066] The inner side of the sealing frame 631 is provided with several sealing plates 632. Each sealing plate 632 has a rotating shaft B633 fixed on both sides. The rotating shaft B633 passes through the inner wall of the sealing frame 631 and is rotatably connected to the sealing frame 631. Each sealing plate 632 has a guide rod 634 fixed on the side near the top plate 623. The sealing frame 631 has an arc-shaped guide groove 635 at the position corresponding to the guide rod 634. The guide rod 634 is slidably connected to the sealing frame 631 through the arc-shaped guide groove 635. The surface of the top plate 623 has a Z-shaped guide groove 625 at the position corresponding to the guide rod 634. The end of the guide rod 634 extending outside the sealing frame 631 is inserted into the Z-shaped guide groove 625 and is slidably connected to the top plate 623.

[0067] In this implementation scheme: Before performing the above-mentioned flipping movement, the operator can control the start of the air pump 641 to extend the pneumatic telescopic rod 643, which drives the sealing frame 631 to move downward. When the sealing frame 631 moves downward, the guide rod 634 slides along the Z-shaped guide groove 625, causing the sealing plate 632 to rotate. Several sealing plates 632 form a plane and press against the surface of the tray 5, so that the tray 5 is in a sealed state. At this time, the above-mentioned flipping movement can be performed to a greater extent, allowing the tray 5 to be flipped 360°, while preventing the tray 5 and the equipment in the tray 5 from falling off. After the tray 5 is reset, the air pump 641 is controlled to reset the sealing frame 631, and the sealing plate 632 is reset at the same time. A gap is formed between the sealing plates 632 to avoid affecting the detection intensity of the scanning antenna 4.

[0068] Furthermore:

[0069] like Figure 4 , Figure 6 and Figure 7 As shown;

[0070] In an optional embodiment, the turning point of the Z-shaped guide groove 625 is formed by splicing two tangent quarter-circle arc grooves, and the distance between the rotating shaft B633 and the guide rod 634 is equal to the center distance between the two arc grooves in the Z-shaped guide groove 625.

[0071] In this embodiment: This design allows the guide rod 634 to move smoothly in the Z-shaped guide groove 625, avoiding the guide rod 634 getting stuck at the turning point in the Z-shaped guide groove 625.

[0072] Furthermore:

[0073] like Figure 4 and Figure 6 As shown;

[0074] In an optional embodiment, the sealing frame 631 is fixed with locking blocks 636 on both sides, and the inner side of the side plate 621 is provided with a groove that matches the locking blocks 636. The sealing frame 631 is slidably connected to the side plate 621 through the locking blocks 636.

[0075] In this embodiment, this design allows the sealing frame 631 to slide smoothly within the side plate 621, improving the reliability of the invention.

[0076] Furthermore:

[0077] like Figure 1 , Figure 10 and Figure 11 As shown;

[0078] To ensure that the scanning range of the scanning antenna 4 covers the entire tray 5, two angle adjustment components 700 arranged upside down are installed at the center of the inner side of the connecting plate 622. The scanning antenna 4 is movably connected to the connecting plate 622 through the angle adjustment components 700. The angle adjustment components 700 include a connecting seat 701 fixed on the connecting plate 622. The connecting seat 701 has an n-shaped plate structure. A guide plate 702 is fixed to one edge of the connecting seat 701. A U-shaped plate structure rotating seat 703 is rotatably connected to the outside of the connecting seat 701. An extension plate is fixed to the side of the rotating seat 703 near the guide plate 702. 704. An adjustment motor 705 is fixed on the side of the extension plate 704 away from the guide plate 702. A rocker arm 706 is provided between the guide plate 702 and the extension plate 704. The output end of the adjustment motor 705 passes through the extension plate 704 and is connected to the rocker arm 706. A sliding column 707 is rotatably connected to the end of the rocker arm 706 away from the output end of the adjustment motor 705. The sliding column 707 extends into the slide groove of the guide plate 702 and is slidably connected to the guide plate 702. Another set of angle adjustment components 700 is fixed on the bottom side of the rotating seat 703. The scanning antenna 4 is fixed on the connecting seat 701 away from the connecting plate 622.

[0079] In this implementation scheme: when the scanning antenna 4 is scanning, the adjustment motor 705 can be started. The adjustment motor 705 drives the rocker arm 706 to rotate, so that the sliding column 707 drives the guide plate 702 and the connecting seat 701 to rock. When the connecting seat 701 rocks, it drives the scanning antenna 4 to swing, thereby expanding the scanning range of the scanning antenna 4 and enabling the scanning antenna 4 to scan dynamically, thus improving the accuracy of scanning.

[0080] Furthermore:

[0081] like Figure 10 and Figure 11 As shown;

[0082] In an optional embodiment, one angle adjustment component 700 and the other angle adjustment component 700 are arranged with their rotation directions intersecting by 90 degrees.

[0083] In this embodiment: This design enables the scanning antenna 4 to swing in two directions, and the combination of the two swings can maximize the scanning range of the scanning antenna 4.

[0084] Furthermore:

[0085] like Figure 8 As shown;

[0086] In an optional embodiment, both sides of the bottom of the sliding rod 804 and the U-shaped rail B803 are boss structures with a convex cross-section.

[0087] In this embodiment: Through this design, because the sliding rod 804 and the U-shaped rail B803 are subjected to the gravity of the moving platform 821, the end away from the moving platform 821 has a certain upward movement tendency. This design can prevent the sliding rod 804 and the U-shaped rail B803 from separating.

[0088] Furthermore:

[0089] like Figures 1 to 3 As shown;

[0090] In an optional embodiment, the rear side of the housing 1 is open, and storage compartments 11 are rotatably connected to both sides of the housing 1. A cabinet door 12 is opened on the front side of the housing 1 near the lower part of the cover plate 3.

[0091] In this embodiment: Through this design, the storage compartment 11 can temporarily hold the tray 5 with abnormal scanning results or the tray 5 with normal scanning results, which makes it easy for operators to distinguish and use. The cabinet door 12 makes it easy for operators to inspect and maintain the invention.

[0092] Furthermore:

[0093] like Figure 1 , Figure 3 and Figure 9 As shown;

[0094] In an optional embodiment, a limiting groove 824 is formed on the surface of the moving stage 821, and the tray 5 is disposed in the limiting groove 824, the limiting groove 824 matching the tray 5.

[0095] In this embodiment: Through this design, the limiting groove 824 makes the tray 5 installed stably, and at the same time makes it easy for the operator to accurately know the correct installation position of the tray 5, thereby improving the reliability of the invention.

[0096] In summary, this invention uses an external 220V power supply.

[0097] The present invention also provides a method for using an RFID reader, comprising the following steps:

[0098] S1. Press the start switch on the housing 1. The control module controls the start motor 822. The motor 822 drives the gear 823 to make the moving platform 821 extend from the inlet and outlet 626. The cover plate 3 is automatically opened by the pushing force of the moving platform 821.

[0099] S2. Place the tray 5 into the limiting groove 824, press the identification switch on the housing 1, the control module starts the motor 822, the motor 822 drives the gear 823 to retract and reset the moving table 821, and automatically enter the next stage.

[0100] S3. The control module starts the scanning antenna 4 to read and identify the RFID tag fixed on the scanning tray 5, reads and records the pre-existing information such as the type and quantity of equipment in this batch of tray 5, and transmits the pre-existing information to the display module 2. After 3 seconds, it automatically enters the next stage.

[0101] S4. After the information transmission is complete, the control module starts the scanning antenna 4 to read the tags on the equipment in the tray 5, and compares the read equipment information with the previous information. The comparison results are as follows:

[0102] s4.1, The reading and verification are correct;

[0103] s4.2 Lack of equipment;

[0104] s4.3, Additional equipment;

[0105] When situation S4.1 occurs: the display module 2 will indicate that the verification is correct and automatically jump to S6;

[0106] When situation S4.2 occurs: the display module 2 prompts for re-verification and automatically jumps to S5;

[0107] When situation S4.3 occurs: Additional equipment information is displayed on display module 2, and the system automatically jumps to S6;

[0108] S5. The control module starts the air pump 641, pressing the sealing frame 631 down onto the surface of the tray 5. The drive motor 612 starts, causing the housing mechanism 620 to move, dispersing the equipment in the tray 5. After the housing mechanism 620 resets, the sealing frame 631 resets. The adjustment motor 705 starts, causing the connecting seat 701 and the scanning antenna 4 to swing and form a cyclic scan, thereby reading the equipment in the tray 5 from multiple angles again. The verification results are as follows:

[0109] s5.1, The reading and verification are correct;

[0110] s5.2 Lack of equipment;

[0111] When in case S5.1: The display module 2 indicates that the verification is correct and automatically jumps to S6;

[0112] When in situation S5.2: The display module 2 indicates that equipment information is missing, and it automatically jumps to S6;

[0113] S6. Once identification is complete, the control system starts the motor 822. The motor 822 drives the gear 823 to extend the moving platform 821 from the inlet / outlet 626 and stop there.

[0114] S7. After completing the identification and verification of all equipment, press the shut-off switch on the housing 1. The control module controls the start motor 822, which drives the gear 823 to retract and reset the moving platform 821.
