Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of logistics scanning equipment and relates to an automatic top-scanning device for mail. Background Technology
[0002] With the rapid development of postal delivery services, zippered reusable mailbags equipped with RFID tags are now widely used in the parcel collection process, and their usage rate is rapidly increasing. In 2022, postal groups used mailbags 293 million times, with reusable mailbags accounting for 45.95%. Currently, the postal network lacks RFID tag reading and writing equipment, resulting in the inability to identify RFID tags in zippered reusable mailbags. The loading and unloading process mainly relies on PDAs to scan the printed barcodes on each reusable mailbag, which is slow and labor-intensive. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing an automatic mail top-scanning device that can simultaneously identify printed barcodes and RFID tags, thereby improving the efficiency of mail import and export processing and reducing the labor intensity of employees.
[0004] The objective of this utility model can be achieved through the following technical solution: an automatic top-scanning device for mail, characterized in that the device includes a rectangular cabinet, with a conveyor belt at the top of the cabinet; a top-scanning bracket is fixed at the middle of the top of the cabinet, and the top-scanning bracket spans over the conveyor belt; the cabinet contains a computer, an RFID reader / writer, and a motor that drives the conveyor belt; several area array barcode cameras, RFID antennas, and cameras are fixed on the top-scanning bracket; each of the area array barcode cameras and cameras is connected to the computer via a network cable, and the RFID antenna is connected to the RFID reader / writer and then connected to the computer via a network cable or a serial cable.
[0005] Preferably, a fixed support leg is fixed to the bottom of one end of the cabinet, and a swing frame and a servo motor are hinged to the bottom of the other end of the cabinet; a crossbar is rotatably connected to the middle position of the swing frame, and a sleeve is fixed to the middle of the crossbar; a screw is coaxially fixed to the output shaft of the servo motor, the screw is inserted into the sleeve, and the screw and the sleeve are threaded together.
[0006] Preferably, each of the fixed support legs and the swing frame has a roller rotatably connected to its lower end.
[0007] The advantages of this utility model are:
[0008] 1. This device uses both barcode recognition and REID technology, making its application scenarios more extensive and reducing manual labor intensity.
[0009] 2. The height of one end of this device is adjustable, making it more compatible with the upstream conveying equipment and more convenient to use. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic top-scanning device for mail includes a rectangular cabinet 1 with a conveyor belt 2 at the top. A top-scanning bracket 3 is fixed at the middle of the top of the cabinet 1, and the top-scanning bracket 3 spans above the conveyor belt 2. The cabinet 1 contains a computer 4, an RFID reader / writer 5, and a motor that drives the conveyor belt 2. Several area array barcode cameras 6, RFID antennas 7, and cameras 8 are fixed on the top-scanning bracket 3. Each area array barcode camera 6 and camera 8 is connected to the computer 4 via a network cable. The RFID antenna 7 is connected to the RFID reader / writer 5 and then connected to the computer 4 via a network cable or a serial cable.
[0016] In practical application, mail is conveyed orderly by the conveyor belt 2 under the top-scanning bracket 3. The top-scanning bracket 3 is equipped with a barcode camera 6 and a REID antenna. The REID antenna first senses and identifies zippered reusable mailbags or mail with RFID tags, then transmits the information to the RFID reader 5. After signal analysis, the RFID reader 5 transmits the RFID tag barcode information to the top-scanning software on the computer 4. Mail without RFID tags is photographed by the barcode camera 6, analyzed by dedicated software, and the printed barcode is transmitted to the top-scanning software on the computer 4. The top-scanning software on the computer 4 is responsible for feeding back the relevant RFID tag barcode or printed barcode information to the logistics platform. This top-scanning device can simultaneously identify RFID tags and printed barcodes, expanding the application scenarios of the top-scanning equipment and reducing manual labor intensity. The top-scanning bracket 3 is also equipped with a camera 8, which can dynamically record the movement of mail within the device and store it on the computer 4 for 60 days. Combined with the barcode camera, it enables the storage of both static and dynamic status information of the mail.
[0017] like Figure 1 , Figure 2 and Figure 3 The bottom of one end of the cabinet 1 is fixed with a fixed support leg 11, and the bottom of the other end of the cabinet 1 is hinged with a swing frame 12 and a servo motor 13. A crossbar 14 is rotatably connected at the middle position of the swing frame 12, and a sleeve 15 is fixed in the middle of the crossbar 14. A screw 16 is coaxially fixed on the output shaft of the servo motor 13. The screw 16 is inserted into the sleeve 15, and the screw 16 and the sleeve 15 are threadedly connected. In the actual application of this device, mail is usually transported to its conveyor belt 2 by the upstream conveying equipment. In order to better connect it with the upstream equipment, we must make the height of its feeding end adjustable so that it matches the height of the upstream equipment. Therefore, we set a hinged motor and swing frame 12 at one end. The motor can drive the screw 16 to rotate, and the rotation of the screw 16 can drive the swing frame 12 to swing, thereby adjusting the distance between the bottom of the swing frame 12 and the bottom of the cabinet 1, thereby realizing the height adjustment of that end of the cabinet 1.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, each fixed support leg 11 and the lower end of the swing frame 12 are rotatably connected to a roller 17. The presence of the roller 17 makes the device easier to move.
[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
