Description

Technical Field

[0001] This utility model relates to the field of tool storage technology, and in particular to an RFID tool cart. Background Technology

[0002] Radio Frequency Identification (RFID) technology, also known as wireless radio frequency identification, is a communication technology commonly referred to as electronic tags. It can identify specific targets and read and write related data through radio signals without requiring mechanical or optical contact between the identification system and the specific target.

[0003] Radio signals transmit data from tags attached to objects via electromagnetic fields tuned to radio frequencies, enabling automatic identification and tracking. Some tags draw power from the electromagnetic field emitted by the reader during identification, eliminating the need for batteries; others are powered and actively emit radio waves (electromagnetic fields tuned to radio frequencies). The tags contain electronically stored information and can be identified within a few meters. Unlike barcodes, RFID tags do not need to be within the reader's line of sight and can be embedded within the object being tracked.

[0004] Many industries utilize RFID technology. For example, attaching tags to a car in production allows factories to track its progress on the assembly line. Warehouses can track the location of medicines. RFID tags can also be attached to livestock and pets for active identification (active identification means preventing multiple animals from using the same identity). RFID identification cards allow employees to enter locked parts of buildings, and RFID transponders on vehicles can be used to collect fees for toll roads and parking lots.

[0005] Tools in factory tool carts are often haphazardly arranged, making it difficult to quickly identify which tools are on each shelf. As time goes on, some tools are lost because workers forget to return them, and the loss of some high-value tools can lead to significant losses. Summary of the Invention

[0006] According to an embodiment of the present invention, an RFID tool cart is provided, comprising:

[0007] The frame has several storage areas, which are shielded by a metal layer, with a first opening on one side.

[0009] The drawer contains a near-field antenna; the drawer is also used to store tools with electronic tags.

[0010] The reader / writer is housed within the frame and connected to a near-field antenna inside the drawer.

[0011] The control panel is mounted on the frame and connected to the reader / writer.

[0012] Furthermore, a first shielding strip is provided at the top of the first opening. The first shielding strip is Z-shaped, with its upper side connected to the frame and its lower side forming a first slot with the frame. A second shielding strip is provided on the drawer, and the second shielding strip is coupled to the first slot.

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0030] First, combine Figures 1-8 The RFID tool cart according to an embodiment of the present invention is used for storing tools and has a wide range of applications.

[0031] like Figures 1-8 As shown, the RFID tool cart of this utility model embodiment includes:

[0032] The frame 1 has several storage areas 11. Each storage area 11 is shielded by a metal layer and has a first opening on one side. Each storage area 11 forms a shielded space to prevent internal electromagnetic waves from leaking out and external electromagnetic waves from interfering with it.

[0033] Several drawers 2 correspond one-to-one with several storage areas 11, and are movably set in the corresponding storage area 11 through the first opening; the drawers 2 are made of metal and serve as shielding.

[0034] A near-field antenna 3 is installed inside drawer 2; drawer 2 is used to store tools with electronic tags, and the near-field antenna 3 is used to receive signals from the electronic tags.

[0035] The reader 4 is installed inside the frame 1. The input end of the reader 4 is connected to the output end of the near-field antenna 3 through a line, which ensures that the near-field antenna 3 is not interfered with by external electromagnetic waves and can transmit the signal to the reader 4.

[0036] Control panel 5 is mounted on frame 1 and connected to reader 4. The output of reader 4 is connected to the input of control panel 5 via a line, and transmits signals to control panel 5.

[0037] Preferably, the line between the reader 4 and the near-field antenna 3 can be left with an appropriate length to avoid interference when the drawer 2 is pulled out.

[0038] Furthermore, in another embodiment, the reader 4 and the near-field antenna 3 can also be wirelessly connected. This requires opening a communication window behind the drawer 2 so that the two can communicate via electromagnetic waves.

[0039] Furthermore, such as Figure 5 , 7 As shown, in this embodiment, a first shielding strip 12 is provided at the top of the first opening. The first shielding strip 12 is Z-shaped, with its upper side connected to the frame 1 and its lower side forming a first slot 13 with the frame 1. A second shielding strip 21 is provided on the drawer 2. The second shielding strip 21 is coupled to the first slot 13, which can effectively prevent electromagnetic wave leakage.

[0040] Furthermore, such as Figure 6 As shown, in this embodiment, it also includes: a plurality of electrically controlled locks 6, which are installed inside the frame 1 and electrically connected to the control panel 5, and correspond one-to-one with a plurality of drawers 2. Each drawer 2 is provided with a latch 61 corresponding to an electrically controlled lock 6. When the electrically controlled lock 6 is opened, the drawer 2 will be popped out part of the way, and then the drawer 2 will be manually pulled open.

[0041] Furthermore, such as Figure 2 As shown, in this embodiment, it also includes: an inspection door 7, which is located on one side of the frame 1 and is movably connected to the frame 1 for convenient maintenance.

[0042] Furthermore, such as Figure 1 As shown, in this embodiment, it also includes: a plurality of casters 14, which are arranged at the bottom of the frame 1 to facilitate the movement of the frame 1.

[0043] Furthermore, such as Figure 1 As shown, in this embodiment, it also includes a handle 15, which is disposed on one side of the frame 1.

[0044] Furthermore, in this embodiment, a barcode scanner is also included. The barcode scanner is communicatively connected to the control panel 5. It can scan tools and transmit information to the control panel 5, thereby opening the corresponding drawer 2 and returning the tools. In addition, the corresponding tools can also be retrieved by scanning the QR code on the material requisition form.

[0045] Furthermore, such as Figures 4-5 As shown, in this embodiment, a positioning plate 22 is also provided inside the drawer 2, and the positioning plate 22 is provided with a number of positioning grooves for fixing tools.

[0046] Working principle: Tools with electronic tags are placed in the corresponding drawer 2. The near-field antenna 3 inside drawer 2 transmits the information to the reader 4, which in turn transmits the information to the control panel 5. When a tool needs to be retrieved, the user clicks on control panel 5 or scans the requisition form with a barcode scanner. Control panel 5 then opens the electronic lock 6 of the corresponding drawer 2, causing drawer 2 to pop out. The user can then pull out drawer 2 and retrieve the tool. At this time, the near-field antenna 3 and reader 4 can detect that the tool has been taken. When a tool is returned, the user clicks on control panel 5 or scans the tool with a barcode scanner. Control panel 5 then opens the electronic lock 6 of the corresponding drawer 2, causing drawer 2 to pop out. The user can then pull out drawer 2 and place the tool back in. At this time, the near-field antenna 3 and reader 4 can detect that the tool has been returned. The control panels of multiple RFID tool carts can communicate with the backend system, allowing relevant personnel to monitor the tool usage status throughout the factory in real time.

[0047] Above, refer to Figures 1-8 The present invention describes an RFID tool cart according to an embodiment of the present invention, which allows users to clearly know which tools are placed in each drawer. When a tool is taken out or returned, the corresponding drawer can be opened automatically, making it convenient to take out and put in tools. It is highly intelligent and easy to move.
