Abstract
Description
Technical Field
[0001] This utility model relates to the field of shelving technology, and in particular to a radio frequency identification (RFID) shelving. Background Technology
[0002] With urban development and to meet the people's growing electricity demand, more and more large-scale integrated material equipment is being used in power construction, which places higher demands on warehouses in terms of material storage, handling, and warehousing. Shelving plays a very important role in the logistics system. With the increasing volume of goods and the increasing number of automated warehouses, the number of shelving units will increase, and they will be required to be multifunctional and capable of achieving automation and mechanization.
[0003] A shelf with RFID tags is disclosed in CN218663552U, comprising a base plate, an adjustment mechanism above the base plate, a fixing mechanism above the base plate, and an RFID transmitter above the adjustment mechanism. The adjustment mechanism includes two support columns, each movably mounted on the top of the base plate, and a second support column movably mounted on top of each of the two support columns. This shelf with RFID tags, by incorporating the adjustment mechanism, addresses the common problem of immobilized or disassembled shelves when not in use. Since most shelves are one-piece units, this adjustment mechanism separates the adjustment mechanism from the base plate, while the adjustment mechanism allows the shelf to be folded, facilitating its movement and storage.
[0004] The existing shelving combines storage with RFID, which identifies product tags. It uses a method of storing a group of products and scanning a group of products. Therefore, it is necessary to repeatedly perform operations of storage and scanning. This means that the next group can only be stored after the previous group has been scanned and registered. The time interval between storage is relatively long. When the storage volume is large, the storage time is long, which will affect the actual work efficiency and prolong the storage and registration time.
[0005] Therefore, those skilled in the art have provided a radio frequency identifiable shelf to address the problems mentioned in the background section. Utility Model Content
[0006] The purpose of this invention is to provide a radio frequency identification (RFID) shelf to solve the problem mentioned in the background art that existing shelves cannot achieve RFID identification while storing items.
[0007] To achieve the above objectives, this utility model provides the following technical solution: A radio frequency identification (RFID) shelf includes: a shelf column, a central seat fixedly mounted on the surface of the shelf column, a servo motor installed inside the central seat, an output shaft mounted on the output end of the servo motor, a Hall sensor mounted on the outer side of the output shaft, a turntable fixedly connected to the output end of the output shaft, a fixed top plate fixedly mounted on the bottom of the central seat, a reader mounted on the surface of the fixed top plate, a reader scanning head mounted on the bottom of the reader, a label box slidably mounted on the surface of the turntable, and an electronic tag fixedly mounted on the top of the label box.
[0008] As a further embodiment of this utility model: the servo motor is connected to the turntable via an output shaft, and the turntable is rotatably connected to the shelf column via ball bearings.
[0009] As a further improvement of this utility model: the lower surface of the fixed top plate is arranged opposite to the upper surface of the turntable, and the number of readers and reader scanning heads is the same as the number of label boxes.
[0010] As a further improvement of this utility model: the fixed top plate is fixedly connected to the shelf column, and the fixed top plate and the turntable are arranged in a one-to-one correspondence.
[0011] As a further improvement of this utility model: the fixed top plate and the turntable are both distributed vertically at equal intervals along the surface of the shelf column.
[0012] As a further embodiment of this utility model: a sliding groove is fixedly installed on the upper surface of the turntable, and a magnet is fixedly installed on the inner wall of one end of the sliding groove; a metal slide bar is fixedly installed inside the label box; and the label box is slidably connected to the sliding groove through the metal strip.
[0013] Compared with the prior art, the beneficial effects of this utility model are: A central shelf is installed on the shelf column, and a servo motor is installed inside the central shelf. The servo motor inside the central shelf drives the turntable to rotate. When the turntable rotates, warehouse personnel only need to stand at one point to place the storage items, eliminating the need to constantly change positions and reducing labor intensity. At the same time, a fixed top plate is fixedly installed on the central shelf, and a reader is installed on the surface of the fixed top plate. The reader is used to read and write the electronic tags on the label boxes placed on the turntable. A Hall sensor is installed on the output shaft of the servo motor to detect the rotation angle of the turntable. When the turntable has rotated 360 degrees, all storage on this layer of the turntable is completed. Then, the reader on the fixed top plate is used to simultaneously read and write the electronic tags on the label boxes below to complete the goods registration. The label boxes are placed together. After placement, the electronic tags are identified again. There is no need to store and identify one group at a time, shortening the storage time and improving storage efficiency.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: A radio frequency identification (RFID) shelf includes: a shelf column 1, a middle seat 2 fixedly mounted on the surface of the shelf column 1, a servo motor 3 installed inside the middle seat 2, an output shaft 9 installed at the output end of the servo motor 3, a Hall sensor 10 installed on the outside of the output shaft 9, a turntable 4 fixedly connected to the output end of the output shaft 9, a fixed top plate 5 fixedly mounted at the bottom of the middle seat 2, a reader 6 mounted on the surface of the fixed top plate 5, a reader scanning head 7 mounted at the bottom of the reader 6, a label box 8 slidably mounted on the surface of the turntable 4, an electronic tag 13 fixedly mounted on the top of the label box 8, a slide groove 11 fixedly mounted on the upper surface of the turntable 4, a magnet 14 fixedly mounted on the inner wall of one end of the slide groove 11, a metal slide strip 12 fixedly mounted inside the label box 8, and the label box 8 is slidably connected to the slide groove 11 through the metal strip. Using the sliding structure between the metal strip fixed to the bottom of the label box 8 and the slide groove 11, the label box 8 is pushed into the surface of the turntable 4, with the back of the label box 8 close to the center of the turntable 4. When the end of the metal strip is flush with the end of the slide groove 11, the magnet 14 uses its magnetic attraction to position the metal strip, thus completing the storage and placement of the label box 8. A ball bearing is installed between the turntable 4 and the shelf column 1 for rotation, enabling the turntable 4 to rotate with the shelf column 1. The servo motor 3 inside the intermediate seat 2 drives the turntable 4 to rotate. After storing a set of label boxes 8, rotating the turntable 4 pushes the stored label boxes 8 away. The next set of label boxes 8 is stored. During the storage process, the Hall sensor 10 detects the rotation angle of the turntable 4. When the turntable 4 rotates to 360 degrees, the entire turntable 4 has rotated one revolution, and all the label boxes 8 on this layer of the turntable 4 have been stored. Using the PID control system, after the turntable 4 has finished storing, the label boxes 8 correspond one-to-one with the readers 6 on the fixed top plate 5 above, and then control the corresponding reader scanning head 7 to identify the electronic tags 13 on the label boxes 8, and complete the registration and storage of the goods. In this way, storage and RFID tag identification are completed simultaneously, shortening the storage time and improving work efficiency.
[0020] Servo motor 3 is connected to turntable 4 via output shaft 9, and turntable 4 is rotatably connected to shelf column 1 via ball bearing. The lower surface of fixed top plate 5 is opposite to the upper surface of turntable 4. The number of readers 6 and readers scanning heads 7 is the same as the number of label boxes 8. Fixed top plate 5 is fixedly connected to shelf column 1, and fixed top plate 5 and turntable 4 are arranged in a one-to-one correspondence. Fixed top plate 5 and turntable 4 are both distributed vertically at equal intervals along the surface of shelf column 1. The turntable 4 and the shelf column 1 are connected by a rotating structure, which allows the servo motor 3 to drive the turntable 4 to rotate and change the position of the slide groove 11 on the turntable 4, so that the label boxes 8 can be stored one by one. The fixed top plate 5 and the shelf column 1 are connected by a fixed structure. After the turntable 4 has finished storing the label boxes 8, the reader 6 is used to identify the electronic tags 13 on the label boxes 8. A set of label boxes 8 corresponds to a set of electronic tags 13. The turntable 4 and the fixed top plate 5 are distributed in several layers at equal intervals along the shelf column 1 to increase the storage capacity.
[0021] The working principle of this utility model is as follows: When using this utility model, the label box 8 is first pushed into the surface of the turntable 4 through the slide groove 11. The label box 8 is slidably connected to the slide groove 11 through the internal metal slide bar 12 until the end of the metal slide bar 12 is flush with the end of the slide groove 11. The magnet 14 will use its magnetic attraction to attract the metal slide bar 12, so that the label box 8 is fixed on the turntable 4. Then the servo motor 3 is started, and the turntable 4 is driven to rotate through the output shaft 9. The Hall sensor 10 detects the rotation angle of the turntable 4. When the turntable 4 rotates 360 degrees, the entire turntable 4 completes one rotation, completing the storage of all the label boxes 8 on this layer of the turntable 4. Each label box 8 can correspond one-to-one with the reader 6 on the fixed top plate 5 above. The reader 6 identifies the electronic tag 13 on the label box 8 through the reader scanning head 7 at its bottom, completing the registration and storage of the goods. The entire process simultaneously completes storage and RFID tag identification, effectively shortening the storage time and improving work efficiency.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
