[0027] Please see Figure 1-5This utility model provides a technical solution: an RFID smart shelf, including a shelf part 1, which is composed of several partitions 11 and left and right side supports 12. An antenna scanning part 2 is provided on one side of the shelf part 1. The antenna scanning part 2 includes a support frame 21, an X-axis drive mechanism, a Y-axis drive mechanism, a Z-axis drive mechanism, a slider 7, a slide beam 5, and an antenna 3.
[0028] The X-axis drive assembly can be connected to a motor on each of the upper and lower screws, and the X-axis power transmission source in this case is as follows:
[0029] like Figure 3 and Figure 4 As shown, in the X-axis power transmission source, a set of transverse guide rails 41 are arranged between the support frames 21, and transverse screws 42 are rotatably connected to the transverse guide rails 41. Slide beams 5 are respectively engaged with the transverse screws 42 on the upper and lower transverse guide rails 41. The X-axis drive includes a first motor 43, a set of pulleys 44, and a belt 45. The output shaft of the first motor 43 is connected to one of the transverse screws 42, the set of pulleys 44 is connected to the same side of the set of transverse screws 42, and the belt 45 is engaged with the set of pulleys 44. When the first motor 43 starts, it drives the transverse screws 42 to rotate. Through the transmission of the pulleys 44 and the belt 45, it drives the lower transverse screw 42 to rotate, achieving synchronous rotation of the two transverse screws 42, causing the slide beams 5 to move along the X-axis.
[0030] like Figure 5 As shown, in the Y-axis drive mechanism, the vertical screw 61 is installed inside the slide beam 5, the slider 7 is engaged with the vertical screw 61, and the antenna 3 is connected to the slider 7.
[0031] The Y-axis power transmission source can be a motor directly connected to the vertical screw 61. As shown in Figure 1 of this embodiment, the Y-axis power transmission source includes a splined shaft 81, a second motor 82, a driving bevel gear 83, a driven bevel gear 84, and a connecting frame 85. The splined shaft 81 rotates laterally within the support frame 21. The output shaft of the second motor 82 is connected to the splined shaft 81. One end of the connecting frame 85 is connected to the slide beam 5, and the other end is slidably connected within the splined shaft 81. The driving bevel gear 83 is pivotally connected to one end of the connecting frame 85, and its center meshes with the splined shaft 81. The driven bevel gear 84 is located at the output end of the vertical screw 61 and meshes with the driving bevel gear 83. When the second motor 82 starts, it drives the splined shaft 81 to rotate, which in turn drives the driving bevel gear 83 to rotate. The driving bevel gear 83, through meshing with the driven bevel gear 84, drives the vertical screw 61 to rotate, causing the slider 7 and the antenna 3 to move along the Y-axis.
[0032] The arrangement of the X-axis power transmission source and Y-axis drive transmission source in this embodiment allows the first motor 43 and the second motor 82 to be integrated on one side of the bracket 12 frame, which is safer and easier to maintain, and also reduces the burden on the Y-axis drive transmission source set on the slide beam 5.
[0033] The Z-axis drive mechanism consists of a set of electrically operated telescopic components 15, which are installed on both sides of the slider 7. The telescopic rods of the electrically operated telescopic components 15 are connected to the antenna 3. First, the Y-axis drive mechanism moves the antenna 3 to the desired scanning layer 11. Then, the electrically operated telescopic components 15 extend the antenna 3 above the goods. Next, the X-axis drive mechanism moves the antenna 3 above the goods along the X-axis of the shelf. When a layer needs to be changed for scanning, the electrically operated telescopic components 15 retract the antenna 3, and then the Y-axis drive mechanism adjusts it to the desired scanning layer 11. The electrically operated telescopic components 15 extend the antenna 3 again, and the X-axis drive mechanism moves the antenna 3 on the goods in the X-direction for scanning.
[0034] The first motor 43 and the second motor 82 are located on the same side of the support frame 21 and are covered by a protective outer shell 9. The support frame 21 is located near the shelf section 1 and is connected to the support bracket 12 of the shelf section 1 via a U-shaped frame 10. The first motor 43 and the second motor 82 are respectively connected to the output ends of the horizontal screw 42 and the vertical screw 61 via couplings 14. An alarm 13 is installed on the shelf section 1. In addition to basic scanning functions, it also has an alarm function. When unauthorized goods are taken, it can promptly issue an alarm, improving the security of the shelf. At the same time, through the processing and analysis of scanning data by the control center, functions such as real-time recording of item issuance and return data and storage location binding can be realized, facilitating the management and retrieval of goods.
[0035] In actual use, the control center controls the start and stop of the first motor 43, the second motor 82, and the electric telescopic component 15, causing the antenna 3 to scan the goods on the shelf according to a predetermined path. When the antenna 3 identifies goods, it transmits the information to the control center for processing and recording. If unauthorized access to goods is detected, the control center will trigger the alarm 13 to issue an alarm notification.
[0036] The first motor 43, the second motor 82, the electric telescopic component 15, and the control center are all existing technologies and can be selected and configured according to actual needs.
[0037] Working principle: When the RFID smart shelf is in use, when goods are scanned using this RFID smart shelf, the control center sends commands to the X-axis drive assembly and the Y-axis drive assembly. The first motor 43 in the X-axis drive assembly starts, driving the upper transverse screw 42 to rotate, and simultaneously driving the lower transverse screw 42 to rotate synchronously through the pulley 44 and belt 45, so that the slide beam 5 moves along the transverse guide rail 41 in the X-axis direction. Since the active bevel gear 83 and the output shaft of the second motor 82 are connected by the spline shaft 81, when the slide beam 5 moves in the X-axis, the active bevel gear 83 can slide on the spline shaft 81 driven by the connecting frame 85. At the same time, the second motor 82 in the Y-axis drive assembly starts, driving the spline shaft 81 to rotate. The spline shaft 81 drives the vertical screw 61 to rotate through the meshing transmission of the active bevel gear 83 and the driven bevel gear 84, thereby driving the slider 7 and the antenna 3 connected to the slider 7 to move in the Y-axis direction. Through coordinated movement in the X, Y, and Z axes, antenna 3 can scan the goods on each shelf 11 of the shelf section 1, read the RFID tag information on the goods, and transmit the information to the control center for processing and storage.
[0038] For example, in the diagram, the three-layer shelf 11 can hold 6 boxes with ETC electronic tags. The control center of the smart shelf can set up regular inventory checks via a touch screen. During inventory checks, antenna 3 scans the first box from the left side of the top first layer and then sends the scan data back to the control center. After the control unit obtains the data, it sends an instruction to continue moving to the next box for scanning.
[0039] When unauthorized use of goods occurs, the alarm 13 of the shelf section 1 will sound an alarm signal to remind staff to pay attention to the safety of the goods.
[0040] In practical applications, the X-axis and Y-axis power transmission sources can be set via the control center according to the size of the shelf and the placement of goods, so as to adjust the scanning path and speed of antenna 3 and achieve the best scanning effect.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
