Description

Technical Field

[0001] This utility model relates to the field of RFID data collection equipment technology, and in particular to an RFID data collection device that can be connected to smart logistics. Background Technology

[0002] In the current era of rapid development in the smart logistics industry, accurate and efficient collection of cargo information is a core element for achieving visualized and intelligent management of the logistics chain. RFID technology, with its advantages of non-contact identification, strong batch processing capabilities, and large data storage capacity, has become the mainstream technical solution in the field of logistics information collection. However, most RFID collection devices on the market use fixed scanning heads. When collecting information from goods with attached tags, blind spots are easily created due to incomplete scanning angle coverage, resulting in some goods' RFID tags not being effectively identified. This leads to missed or incorrect data collection, requiring manual secondary verification, increasing labor costs, and potentially causing misdelivery or missing shipments due to information errors, thus affecting the quality of logistics services.

[0003] Meanwhile, most RFID data collection devices integrate weighing functions. However, the weighing mechanisms of existing integrated devices are mostly rigidly connected designs. The impact force generated when goods are placed can easily cause momentary overload of the weighing sensors, affecting weighing accuracy. Furthermore, the weighing and feeding processes of some devices are not well coordinated. After weighing, the feeding mechanism cannot adaptively adjust to changes in the weighing platform height caused by the weight of the goods, which can easily lead to feeding jams or goods tipping over, hindering the continuity of the operation process. Therefore, there is a need for an RFID data collection device that can eliminate scanning blind spots, improve weighing accuracy, and achieve adaptive coordination between weighing and feeding to meet the needs of intelligent logistics systems for accurate information collection and efficient operation processes.

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] Example 1

[0031] like Figure 1-8 As shown in the figure, an RFID collection device capable of interfacing with smart logistics according to an embodiment of the present invention includes: a base 1, a side plate 2 and a mounting base 3 fixedly connected to the base 1, a conveying mechanism 4 and a positioning plate 5 fixedly installed on the inner side of the side plate 2, a spring 6 fixedly connected to the positioning plate 5, a weighing platform 7 fixedly connected to the top of the spring 6, a U-shaped frame 8 fixedly connected to the upper surface of the mounting base 3, a cylinder 9 fixedly connected inside the U-shaped frame 8, a material dropping plate 10 fixedly connected to the output end of the cylinder 9, an adjustment mechanism 11 provided on the U-shaped frame 8, the adjustment mechanism 11 including a drive motor 111, a disc 112, an annular guide rail 113, a connecting rod 114 and a connecting frame 115, and a scanning collection head 12 fixedly installed at the bottom of the connecting frame 115;

[0032] The U-shaped frame 8 is fixedly connected to the drive motor 111. The output end of the drive motor 111 is fixedly connected to the disc body 112. A column 1121 is provided at the eccentric position of the disc body 112. The column 1121 is slidably connected to the annular guide rail 113. The annular guide rail 113 is fixedly connected to the connecting rod 114. The end of the connecting rod 114 is fixedly connected to the connecting frame 115. The connecting frame 115 is slidably connected to the slide groove 81 of the U-shaped frame 8. The connecting frame 115 has an I-shaped structure. The conveying mechanism 4 includes a servo motor 41, multiple rollers 42, and a conveyor belt 43. The conveyor belt 43 is connected to the multiple rollers 42. The end of one of the rollers 42 is fixedly connected to the output end of the servo motor 41. The servo motor 41 is fixedly mounted on the side plate 2. There are two side plates 2 arranged symmetrically. Both side plates 2 are rotatably connected to the multiple rollers 42.

[0033] The U-shaped frame 8 is externally fixedly connected to a fixed plate 82, and an electric push rod 83 is fixedly connected to the fixed plate 82 along the inclined direction. The output end of the electric push rod 83 is fixedly connected to a push plate 84. Multiple shafts 13 are rotatably connected to the top of the side plate 2, and auxiliary wheels 14 are fixedly connected to the outside of each shaft 13. A pressure sensor 15 is provided on the positioning plate 5, and the pressure sensor 15 is electrically connected to the cylinder 9. A buffer pad 71 is fixedly connected to the lower surface of the weighing platform 7, and the buffer pad 71 is located above the pressure sensor 15. Limiting plates 16 are fixedly connected to both sides of the positioning plate 5, and the limiting plates 16 are slidably connected to the weighing platform 7.

[0034] In this embodiment, the servo motor 41 drives the roller 42 to drive the conveyor belt 43 to rotate. The goods are transported with the conveyor belt 43. The auxiliary wheel 14 on the side plate 2 provides lateral guidance to prevent deviation, so that the goods are delivered to the weighing platform 7. At this time, the weighing platform 7 collects the weight of the goods, and the weight data is synchronized to the intelligent logistics system. Then, the drive motor 111 drives the disc 112 to rotate. The disc 112 slides in the annular guide rail 113 through the eccentric column 1121, thereby driving the matching frame 115 and the scanning head 12 to reciprocate along the length of the U-shaped frame 8 through the connecting rod 114. The RFID information is collected in a comprehensive manner and uploaded to the system. Next, the goods press the weighing platform 7 to compress the spring 6. Then, the pressure sensor 15 triggers a signal, and the cylinder 9 pushes the dropping plate 10 to fall, so that the weighing platform 7 docks with the dropping plate 10. Then, the electric push rod 83 drives the push plate 84 to push the goods to the conveying channel.

[0035] Example 2

[0036] like Figure 1-8As shown in the figure, this utility model embodiment provides an RFID data collection device that can interface with smart logistics. It includes a base 1, on which a side plate 2 and a mounting base 3 are fixedly connected. A conveying mechanism 4 and a positioning plate 5 are fixedly installed on the inner side of the side plate 2. After the device is started, the goods are placed on the conveying mechanism 4. When the goods move with the conveying mechanism 4 to the weighing platform 7 and fall into the weighing platform 7, the weighing platform 7 generates downward pressure under the action of the weight of the goods. At this time, since the weighing platform 7 is elastically connected to the positioning plate 5 through the spring 6, and the limiting plates 16 on both sides of the positioning plate 5 maintain a sliding fit with the weighing platform 7, the weighing platform 7 will move smoothly down along the guide direction of the limiting plates 16. At the same time, the spring 6 is compressed, and the buffer pad 71 fixed on the lower surface of the weighing platform 7 moves down synchronously and comes into contact with the pressure sensor 15 on the positioning plate 5. The pressure sensor 15 converts the sensed pressure signal into weight data, which is synchronized to the smart logistics system in real time to complete the collection and uploading of the weight information of the goods. The buffer pad 71 effectively prevents the weight of the cargo from directly impacting the pressure sensor 15, ensuring the accuracy of the weighing data and the service life of the sensor.

[0037] While the goods are initially weighed, the adjusting mechanism 11 drives the scanning head 12 to start RFID information collection, and starts the drive motor 111 to drive the disc 112 to rotate at a constant speed. A column 1121 is set at the eccentric position of the disc 112 and slides in the annular guide rail 113, so that the annular guide rail 113 drives the connecting rod 114 and the matching frame 115 to move. At this time, the matching frame 115 drives the scanning head 12 to move back and forth, thereby collecting information from the goods.

[0038] Next, after the weight data and RFID information are collected, the pressure sensor 15 triggers a control signal under the continuous pressure of the weighing platform 7. This signal is transmitted to the cylinder 9 to start it. The cylinder 9 pushes the material drop plate 10 to move down synchronously through the piston rod until the material drop plate 10 and the weighing platform 7 carrying the goods are smoothly connected, forming a transition channel for the transport of goods.

[0039] Example 3

[0040] like Figure 1-8 As shown in the figure, an embodiment of the present invention provides an RFID collection device that can be connected to smart logistics. It includes a base 1, a side plate 2 and a mounting base 3 fixedly connected to the base 1, a U-shaped frame 8 fixedly connected to the upper surface of the mounting base 3, and an adjustment mechanism 11 provided on the U-shaped frame 8. The adjustment mechanism 11 includes a drive motor 111, a disc 112, an annular guide rail 113, a connecting rod 114 and a connecting frame 115. When the goods are initially weighed, the adjustment mechanism 11 immediately drives the scanning head 12 to start the RFID information collection operation.

[0041] Specifically, firstly, the drive motor 111 drives the disc 112 to perform uniform circular motion. The disc 112, as a motion conversion component, has a column 1121 fixedly mounted at an eccentric position, forming an eccentric transmission structure. The column 1121 is embedded in the guide groove of the annular guide rail 113 with a clearance fit, allowing the column 1121 to slide smoothly along the inner wall of the annular guide rail 113. The annular guide rail 113 is rigidly connected to the mounting frame 115 via a connecting rod 114. When the disc 112 drives the column 1121 in circular motion, due to the constraint of the guide groove of the annular guide rail 113, the circular motion of the column 1121 is decomposed into sliding along the inner wall of the annular guide rail 113 and a horizontal thrust on the annular guide rail 113. This, in turn, drives the annular guide rail 113 to generate a horizontal reciprocating driving force on the connecting rod 114, thereby driving the mounting frame 115 to achieve linear motion.

[0042] Meanwhile, the connecting frame 115 maintains a sliding fit with the slide groove 81 of the U-shaped frame 8, and the connecting frame 115 adopts an I-shaped structure design to ensure its stability during sliding. Finally, the connecting frame 115 drives the bottom-fixed scanning head 12 to reciprocate linearly along the length of the U-shaped frame 8, so that the scanning head 12 can cover the RFID tag information of the goods, realizing comprehensive and blind-spot-free collection of the RFID tag information of the goods. The collected RFID information will be uploaded to the intelligent logistics system in real time and correlated with the previously uploaded weight data.

[0043] Example 4

[0044] like Figure 1-8 As shown in the figure, in this embodiment of the present invention, an RFID collection device U-shaped frame 8 capable of docking with intelligent logistics has a fixed plate 82 externally fixedly connected. An electric push rod 83 is fixedly connected to the fixed plate 82 along an inclined direction. A push plate 84 is fixedly connected to the output end of the electric push rod 83. After the cargo information is collected, and after the unloading plate 10 and the weighing platform 7 are docked, the electric push rod 83 fixed along the inclined direction on the fixed plate 82 receives an action command, driving the push plate 84 to move towards the cargo along the inclined direction. Then, the push plate 84 smoothly pushes the cargo on the weighing platform 7 into the conveying channel of the unloading plate 10, completing the entire process of a single cargo shipment. It should be noted that the electric push rod 83, set along the inclined direction, does not affect the transport of cargo on the conveying mechanism 4 when not in use. After weighing is completed, the piston rod of the electric push rod 83 moves along the inclined direction to contact the cargo until it is pushed away. After the goods leave, each mechanism resets under the control system. The electric push rod 83 retracts, driving the push plate 84 back to its original position. The cylinder 9 retracts, driving the dropping plate 10 to rise. The weighing platform 7 resets under the elastic restoring force of the spring 6. The pressure sensor 15 releases the pressure signal, and the equipment waits for the next item to enter the processing flow, realizing continuous operation.

[0045] Example 5

[0046] like Figure 1-8 As shown in the figure, this utility model embodiment discloses an RFID data collection device capable of interfacing with intelligent logistics. It includes a base 1, with side plates 2 and mounting bases 3 fixedly connected to the base 1. A conveying mechanism 4 is fixedly installed on the inner side of the side plates 2. A servo motor 41 fixed on the side plates 2 drives a roller 42 connected to its output end to rotate. Since multiple rollers 42 are connected to a conveyor belt 43, and the symmetrically arranged side plates 2 provide stable support for the rollers 42, the conveyor belt 43 forms a uniform speed conveying surface. Goods for which RFID information is to be collected enter the device from the input end of the conveyor belt 43. During the conveying process, auxiliary wheels 14 form two sets of parallel lateral guide structures, constraining the edges of the goods. When the goods tend to deviate, their edges contact the auxiliary wheels 14 and push them to rotate. Without affecting the forward speed of the goods, the guiding action of the auxiliary wheels 14 corrects the posture of the goods, ensuring that the goods are accurately conveyed along the centerline of the conveyor belt 43 to the bearing area of ​​the weighing platform 7, providing a preliminary guarantee for the accurate implementation of subsequent weighing and RFID data collection processes.
