Description

Technical Field

[0001] This utility model relates to the technical field of information collection equipment for automated warehouses with turnover baskets, and in particular to an RFID collection device for automated warehouses with turnover baskets. Background Technology

[0002] RFID (Radio Frequency Identification) technology is a key automated data collection device in automated warehouses for tote containers. It enables automatic identification and information collection of the tote containers, significantly improving the efficiency and accuracy of warehouse management.

[0003] When a crate enters the working area of ​​the RFID data collection device, the antenna emits a radio frequency signal, activating the RFID tag attached to the crate. Upon receiving the signal, the tag reflects its stored information (such as the crate's number, goods information, production date, etc.) back to the antenna via the radio frequency signal. The reader receives the reflected signal, demodulates and decodes it, converting it into digital information that a computer can recognize. Then, the controller processes this information and transmits it to the warehouse management system, enabling the collection and updating of crate information.

[0004] When turnover baskets enter and leave the warehouse, there is no need for manual scanning or registration of each one. RFID collection devices can quickly and in batches read the information of the turnover baskets. For example, at the warehouse entrance, turnover baskets filled with goods continuously enter via a conveyor belt. The RFID collection device can simultaneously read the tag information of multiple turnover baskets, quickly completing the entry registration and greatly improving the speed of warehousing. Similarly, information verification and recording can be quickly completed when leaving the warehouse, reducing vehicle waiting time and improving the logistics turnover efficiency of the warehouse.

[0005] The information collected by RFID data collection devices for turnover baskets contains a wealth of data, such as the origin of the goods, production date, and handler. This information enables traceability throughout the supply chain. However, existing RFID data collection devices require adjustments to the position of the RFID antenna collection unit when scanning turnover baskets at different locations. Currently, a drive unit (such as a cylinder or rack and pinion drive) is typically used to move the RFID antenna collection unit. To ensure the smooth movement of the RFID antenna collection unit, a guide rod is usually placed on the opposite side of the drive unit to guide its movement. However, this setup, due to its large spacing, cannot effectively guarantee the stability of the RFID antenna collection unit's movement. Utility Model Content

[0006] In view of this, the technical problem to be solved by this utility model is: how to provide an RFID collection device for a three-dimensional warehouse for turnover baskets, so as to improve the stability of the moving block and the crossbar during the movement process by setting the guide rod on the moving block that cooperates with the screw, thereby ensuring the stability of the turnover baskets when performing RFID scanning.

[0007] To achieve the above objectives, this application provides an RFID data collection device for a three-dimensional warehouse with turnover baskets, which includes a frame, a drive unit, a crossbar, and an RFID antenna data collection unit.

[0008] The two drive units are respectively disposed on both sides of the width direction of the frame and are respectively connected to both ends of the cross frame. The RFID antenna acquisition unit is disposed on the cross frame. The drive units drive the cross frame and the RFID antenna acquisition unit to move along the length direction of the frame.

[0009] The drive unit includes a first support plate, a second support plate, a motor, a screw, a moving block, a threaded connection, and guide rods. The first and second support plates are arranged vertically and located at opposite ends of the frame along its length. The motor is fixedly mounted at one end of the frame along its length. The output end of the motor is connected to the screw, and the other end of the screw is rotatably connected to the first support plate. The screw passes through the second support plate, which is located between the first support plate and the motor. The threaded connection is mounted on the moving block, with a threaded hole inside and threadedly connected to the outer wall of the screw. The moving block has multiple connecting holes, and multiple guide rods pass through these connecting holes, with both ends of each guide rod fixedly connected to the first and second support plates. The rotation of the motor's output end, along with the transmission from the screw and the threaded connection, drives the moving block to move along the extension direction of the guide rods.

[0010] Furthermore, a plurality of the connecting holes are arranged around the periphery of the screw connection.

[0011] Furthermore, the guide rod and the screw are arranged in parallel, and both the screw and the guide rod are arranged along the length direction of the frame.

[0012] Furthermore, both ends of the crossbeam are fixed to the movable block.

[0013] Furthermore, the four connecting holes are located on the periphery of the screw connection, and the line connecting the centers of the four connecting holes forms a rectangle.

[0014] Compared with related technologies, the RFID data collection device for a three-dimensional warehouse for turnover baskets proposed in this utility model has the following advantages: The rotation of the motor output and the transmission of the screw and threaded connection drive the moving block to move along the extension direction of the guide rod, thereby moving the cross frame and the RFID antenna data collection unit to scan the turnover baskets. To ensure the stability of the moving block, multiple connecting holes are provided around the outside of the threaded connection on the moving block, and multiple guide rods are respectively inserted into the connecting holes. Thus, the moving block, as a moving unit driven by the screw, is directly guided by the guide rods, effectively ensuring the stability and smoothness of the moving block's movement. The guide rods provided on the moving block that cooperates with the screw improve the stability of the moving block and the cross frame during movement, thereby ensuring the stability of the turnover baskets during RFID scanning.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figure 1-2 As shown, this application provides an RFID data collection device for a three-dimensional warehouse with turnover baskets, which includes a frame 10, a drive unit 20, a crossbar 11 and an RFID antenna data collection unit 30.

[0019] Two drive units 20 are respectively located on both sides of the width direction of the frame 10. The two drive units 20 are respectively connected to the two ends of the cross frame 11. An RFID antenna acquisition unit 30 is installed on the cross frame 11. The drive units 20 drive the cross frame 11 and the RFID antenna acquisition unit 30 to move along the length direction of the frame 10.

[0020] Among them, the RFID antenna acquisition unit 30 is an RFID antenna acquisition unit 30, which realizes the information scanning of the turnover basket.

[0021] Specifically, the RFID antenna acquisition unit is a key component of an RFID system. It mainly consists of a reader antenna and a tag antenna. The reader antenna transmits radio frequency signals that activate RFID tags within its operating range. Simultaneously, it is also responsible for receiving radio frequency signals carrying information returned by the tags. Its performance, such as gain and directivity, affects the range and accuracy of data acquisition. For example, a high-gain antenna can expand the acquisition range but may make the signal coverage area more directional.

[0022] The tag antenna receives radio frequency signals emitted by the reader and converts them into electrical energy to power the tag chip. It also transmits the information from the tag chip back to the reader in radio frequency signal form. These two antennas work together to complete data acquisition wirelessly, forming a crucial basic unit for realizing the automatic identification and data acquisition functions of RFID technology.

[0023] The drive unit 20 includes a first support plate 21, a second support plate 22, a motor 23, a screw 24, a moving block 25, a screw connection 26, and a guide rod 27. The first support plate 21 and the second support plate 22 are arranged vertically and are located at both ends of the length direction of the frame 10. The motor 23 is fixedly installed at one end of the frame 10 along its length direction. The output end of the motor 23 is connected to the screw 24. The other end of the screw 24 is rotatably connected to the first support plate 21. The screw 24 passes through the second support plate 22. The second support plate 22 is located between the first support plate 21 and the motor 23. The guide rod 27 and the screw 24 are arranged in parallel. Both the screw 24 and the guide rod 27 are arranged along the length direction of the frame 10.

[0024] The second support plate 22 not only fixes the end of the guide rod 27, but also supports the screw 24, preventing the screw 24 from being too long and causing a large eccentricity at the end of the screw 24 when rotating.

[0025] The screw connection 26 is provided on the movable block 25. The screw connection 26 has a threaded hole inside and is connected to the outer wall of the screw 24 by thread. The movable block 25 is provided with multiple connecting holes 28. Multiple guide rods 27 are respectively passed through the connecting holes 28 and the two ends of the guide rods 27 are respectively fixedly connected to the first support plate 21 and the second support plate 22. The movable block 25 is driven to move along the extension direction of the guide rods 27 by the rotation of the output end of the motor 23 and the transmission of the screw 24 and the screw connection 26. The two ends of the cross frame 11 are respectively fixed on the movable block 25, thereby driving the cross frame 11 through the movable block 25.

[0026] Multiple connecting holes 28 are arranged around the periphery of the threaded part 26. The four connecting holes 28 are respectively located on the periphery of the threaded part 26, and the line connecting the centers of the four connecting holes 28 forms a rectangle. This ensures the overall guiding stability of the periphery of the threaded part 26 that is connected to the screw 24, and prevents the threaded part 26 from being misaligned with the screw 24 or the threaded connection from being misaligned.

[0027] To ensure the stability of the moving block 25, multiple connecting holes 28 are provided around the outside of the screw connection 26 on the moving block 25, and multiple guide rods 27 are respectively inserted into the connecting holes 28. Thus, the moving block 25, as a moving unit driven by cooperating with the screw 24, is directly guided by the guide rods 27, thereby effectively ensuring the stability and smoothness of the moving block 25. By providing guide rods 27 on the moving block 25 that cooperates with the screw 24, the stability of the moving block 25 and the crossbar 11 during the movement is improved, thereby ensuring the stability of the turnover basket when performing RFID scanning.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
