Description

Technical Field

[0001] This invention belongs to the technical field of intelligent pallet tracking, specifically relating to RFID intelligent tracking of plastic pallets. Background Technology

[0002] Radio Frequency Identification (RFID) technology, as a non-contact automatic identification technology, has been widely used in warehousing and logistics, retail, asset management, and smart manufacturing. Traditional RFID tracking systems typically consist of electronic tags, readers, and a backend server. The basic workflow is as follows: the reader reads the unique ID information from the electronic tag and uploads it to the backend server, thereby enabling the tracking and recording of item locations. However, smart sensor electronic tags are generally added to plastic pallets. These tags are usually installed on the plastic pallet using adhesive or nuts. This installation method can lead to the nuts loosening or the tags not being firmly attached during pallet transportation, causing the smart sensor electronic tags to detach from the plastic pallet. Furthermore, it is relatively troublesome to replace damaged tags. This phenomenon has become a problem that urgently needs to be solved by researchers in this field. Summary of the Invention

[0003] The purpose of this invention is to provide an RFID smart tracking plastic tray to solve the problems mentioned in the background art.

[0004] To address the aforementioned technical problems, this invention provides the following technical solution: an RFID smart tracking plastic pallet, comprising a pallet body and a smart sensing electronic tag. An embedding groove is provided on one side of the pallet body, and the smart sensing electronic tag is embedded within the embedding groove. The smart sensing electronic tag integrates an RFID chip, an antenna, at least one environmental sensor, and a microprocessor. The microprocessor collects data from the environmental sensor and transmits this environmental data, along with the tag's ID information, to a terminal via the antenna. The environmental sensor includes a temperature sensor, a humidity sensor, an acceleration sensor, a photosensor, or a vibration sensor. The device can be any one or more combinations of sensors; a reinforcement mechanism is provided between the smart sensor electronic tag and the embedding slot; the reinforcement mechanism includes an insert rod, a nut, and several elastic plates; a circular hole is provided in the middle of the embedding slot; the insert rod is integrally formed in the middle of the inner wall of the circular hole; a countersunk hole is provided in the middle of the smart sensor electronic tag, and the tag is sleeved on the insert rod through the countersunk hole; the rear end of the insert rod is bolt-shaped and threadedly connected to the nut, and the smart sensor electronic tag is fixed by the nut; several elastic plates are evenly welded to the outside of the insert rod, with one end attached to the front side of the smart sensor electronic tag and the other end attached to the inner wall of the circular hole.

[0005] The present invention further illustrates that the inner wall of the circular hole is integrally formed with a convex ring, the front end of the elastic plate is fitted with the convex ring, and the elastic plate is inclined.

[0006] The present invention further illustrates that a transparent plate is attached to the surface of the intelligent sensing electronic tag, and a through hole is provided in the middle of the transparent plate, which is sleeved on the outside of the insertion rod through the through hole; the front side of the nut is tightly attached to the surface of the transparent plate.

[0007] The present invention further illustrates that the inner wall of the circular hole is uniformly distributed and integrally formed with a cylinder. The cylinder is located on the front side of the convex ring. A pneumatic plate is slidably connected to the inner wall of the cylinder. A T-shaped rod is integrally formed on the inner side of the pneumatic plate. The surface of the elastic plate is provided with arc grooves. One end of the T-shaped rod is embedded in the arc groove.

[0008] The present invention further illustrates that the insert rod is provided with an air pressure hole inside, and the outer sides of the cylinders are connected by pipes, and the connected pipes are all in communication with the interior of the air pressure hole.

[0009] The present invention further illustrates that the outer surface of the insertion rod is uniformly provided with air holes, and the air holes are located in the gap between the countersunk hole of the smart sensing electronic tag and the outer surface of the insertion rod; the inner wall of the air pressure hole is slidably connected with a plug, and the plug fits into the air hole.

[0010] The present invention further illustrates that a spring is provided between the outer side of the air pressure plate and the inner wall of the cylinder; two elastic rings are fixed on the rear side of the inner wall of the air pressure hole, and the two elastic rings are arranged opposite to each other; a push rod is integrally formed on the rear side of the plug, and the push rod is embedded between the two elastic rings.

[0011] The present invention further illustrates that the rear end of the top rod is spherical, and both the spherical part and the inner wall of the elastic ring are provided with protrusions, and the protrusions of the elastic ring apply frictional force to the protrusions of the spherical part.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention combines intelligent sensing electronic tags with plastic pallets, reads the unique ID information in the intelligent sensing electronic tags through a reader and uploads it to the backend server, thereby realizing the tracking and recording of the location of items. At the same time, by integrating environmental sensors, the single "identity tracking" is upgraded to a comprehensive perception of "identity + status", which greatly expands the application scenarios and value of plastic pallets. Furthermore, for fixing the smart sensor electronic tag, the operator can attach the smart sensor electronic tag to the insertion rod and tighten the nut to fix the smart sensor electronic tag. The installation and replacement of the smart sensor electronic tag are relatively simple and convenient. At the same time, when fixing the smart sensor electronic tag, the nut applies a force to the smart sensor electronic tag, which causes the smart sensor electronic tag to squeeze the elastic plate, thereby improving the tightness between the smart sensor electronic tag and the nut, preventing the tag from falling off during the transportation of the plastic pallet, and thus improving the reinforcement strength of the tag. By adding a transparent plate, we can prevent oil stains from contaminating the smart sensor electronic tags, which would cause corrosion and reduce their lifespan. On the other hand, we can ensure that the barcodes on the tags are clear, making it easier to scan the tags later, and also blocking dust and oil stains. Attached Figure Description

[0014] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-7 The present invention provides a technical solution: an RFID smart tracking plastic pallet, including a pallet body 1 and a smart sensing electronic tag 2. An embedding groove 11 is provided on one side of the pallet body 1, and the smart sensing electronic tag 2 is embedded in the embedding groove 11. The intelligent sensing electronic tag 2 integrates an RFID chip, an antenna, at least one environmental sensor, and a microprocessor. The microprocessor is used to collect data from the environmental sensor and send the environmental data and the tag's ID information to the terminal through the antenna. The environmental sensor includes any one or more combinations of temperature sensor, humidity sensor, acceleration sensor, photosensor, or vibration sensor. A reinforcing mechanism is provided between the smart sensing electronic tag 2 and the embedding slot 11; The reinforcement mechanism includes an insertion rod 3, a nut 4, and several elastic plates 5. A circular hole 12 is provided in the middle of the embedded groove 11. The insertion rod 3 is integrally formed in the middle of the inner wall of the circular hole 12. A countersunk hole is provided in the middle of the smart sensor electronic tag 2, and it is sleeved on the insertion rod 3 through the countersunk hole. The rear end of the insertion rod 3 is bolt-shaped and threadedly connected to the nut 4, and the smart sensor electronic tag 2 is fixed by the nut 4. Several elastic plates 5 are evenly welded to the outside of the insertion rod 3, with one end attached to the front side of the smart sensor electronic tag 2 and the other end attached to the inner wall of the circular hole 12.

[0016] The inner wall of the round hole 12 is integrally formed with a protruding ring 121, the front end of the elastic plate 5 is attached to the protruding ring 121, and the elastic plate 5 is inclined. By reading the unique ID information in the smart sensor electronic tag 2 through the reader and uploading it to the backend server, the location of the item can be tracked and recorded. At the same time, by integrating environmental sensors, the single "identity tracking" is upgraded to a comprehensive perception of "identity + status", which greatly expands the application scenarios and value of plastic pallets. Furthermore, for fixing the smart sensor electronic tag 2, the operator can attach the smart sensor electronic tag 2 onto the insertion rod 3 and tighten the nut 4 to fix the smart sensor electronic tag 2. The installation and replacement of the smart sensor electronic tag 2 are relatively simple and convenient. At the same time, when fixing the smart sensor electronic tag 2, the nut 4 applies a force to the smart sensor electronic tag 2, which causes the smart sensor electronic tag 2 to compress the elastic plate 5. The elastic plate 5 is limited by the convex ring 121, which causes deformation and applies a reaction force to improve the tightness between the smart sensor electronic tag 2 and the nut 4, preventing the tag from falling off during the transportation of the plastic pallet, thereby improving the reinforcement strength of the tag. Since the elastic plate 5 is inclined, the reaction force gradually increases as the nut 4 is tightened to fully reinforce the tag.

[0017] The surface of the smart sensing electronic tag 2 is covered with a transparent plate 21, and the transparent plate 21 has a through hole in the middle, and is sleeved on the outside of the insertion rod 3 through the through hole. The front side of nut 4 is in close contact with the surface of transparent plate 21; By adding a transparent plate 21, on the one hand, oil stains are prevented from contaminating the smart sensor electronic tag 2, which would lead to corrosion and reduced lifespan. On the other hand, the barcode of the tag is kept clear, making it easy to scan the tag later. It also serves to block dust and oil stains. Furthermore, by applying force to the transparent plate 21 with the nut 4, damage to the smart sensor electronic tag 2 can be reduced when tightening the nut 4, thus ensuring its service life.

[0018] The inner wall of the round hole 12 is evenly distributed and integrally formed with a cylinder 122. The cylinder 122 is located in front of the convex ring 121. The inner wall of the cylinder 122 is slidably connected with a pneumatic plate 123. The inner side of the pneumatic plate 123 is integrally formed with a T-shaped rod 124. The surface of the elastic plate 5 is provided with arc grooves 51. One end of the T-shaped rod 124 is embedded in the arc groove 51.

[0019] The insert rod 3 has an air pressure hole 31 inside, and the outer sides of the cylinder 122 are connected by pipes, and the connected pipes are all connected to the inside of the air pressure hole 31.

[0020] The outer surface of the insertion rod 3 is uniformly provided with air holes, and the air holes are located in the gap between the countersunk hole of the smart sensing electronic tag 2 and the outer surface of the insertion rod 3. A plug 32 is slidably connected to the inner wall of the air pressure hole 31, and the plug 32 fits into the air hole; When installing the smart sensor electronic tag 2, the elastic plate 5 deforms under force, and the T-shaped rod 124 is limited by the arc groove 51, thereby forcing the T-shaped rod 124 to move slightly. The T-shaped rod 124 drives the air pressure plate 123 to slide along the inner wall of the cylinder 122. The gas on the outside of the air pressure plate 123 is compressed and enters the air pressure hole 31 through the pipe. As the gas enters the air pressure hole 31, the internal air pressure gradually increases, thereby pushing the plug 32 to slide along the inner wall of the air pressure hole 31 until the air hole is exposed. The gas quickly enters between the countersunk hole and the outer surface of the insertion rod 3 through the air hole and is ejected through the countersunk hole. When the airflow passes through the transparent plate 21, it blows out the internal dust, thereby relatively reducing the generation of air bubbles and improving the clarity of subsequent label barcode scanning. Meanwhile, the intelligent sensing electronic tag 2 is reinforced and the transparent plate 21 is cleaned simultaneously. This overall linkage reduces manual labor costs and results in a simple and low-cost overall structure.

[0021] A spring is provided between the outer side of the pneumatic plate 123 and the inner wall of the cylinder 122; Two elastic rings 322 are fixed on the rear side of the inner wall of the air pressure hole 31, and the two elastic rings 322 are arranged opposite to each other. A push rod 321 is integrally formed on the rear side of the plug head 32, and the push rod 321 is embedded between the two elastic rings 322. By incorporating a spring, the air pressure plate 123 can be easily reset, facilitating subsequent replacement of the smart sensor electronic tag 2. When the elastic plate 5 drives the T-shaped rod 124 to apply force to the air pressure plate 123, the spring deforms under force and generates a reaction force. This superposition of forces is applied to the smart sensor electronic tag 2 and the nut 4, further improving the tightness between them. Simultaneously, when the plug 32 moves upward under force, it drives the push rod 321 to move. The push rod 321 is embedded between the two elastic rings 322 and receives the reaction force from the elastic rings 322. Through air pressure, this is superimposed on the elastic plate 5, significantly increasing the tightness between the smart sensor electronic tag 2 and the nut 4, effectively preventing the nut 4 from falling off and improving the stability of the smart sensor electronic tag 2 during transportation. Furthermore, when the plug 32 moves backward under force, the reaction force applied by the elastic rings 322 allows the air pressure in the air pressure hole 31 to be stored, enhancing the cleaning strength of dust on the transparent plate 21 and further reducing air bubbles.

[0022] The rear end of the push rod 321 is spherical, and both the spherical part and the inner wall of the elastic ring 322 are provided with protrusions, and the protrusions of the elastic ring 322 apply frictional force to the protrusions of the spherical part. After the spherical part of the push rod 321 is embedded in the elastic ring 322, the elastic ring 322 squeezes the push rod 321. At the same time, the protrusion of the elastic ring 322 rubs against the spherical part, and the friction intensity increases to slow down the reset speed of the plug 32. This ensures that there is enough time to clean the dust on the transparent plate 21, and the gas can be fully ejected until the air pressure in the air pressure hole 31 returns to normal. Then, the elastic ring 322 squeezes the push rod 321 back to its original position.
