Description

Technical Field

[0001] This invention relates to the field of electronic equipment testing, and in particular to a high-efficiency testing device for anti-theft lead seals. Background Technology

[0002] A lead seal is a lock-like device applied by designated personnel after goods are loaded into a container and the container doors are properly closed. Lead seals can be categorized into customs seals, commodity inspection seals, and commercial seals depending on the person applying them. Once properly locked, a lead seal cannot be opened unless forcibly broken. A damaged lead seal cannot be reused. Each lead seal has a unique serial number. As long as the container's exterior is intact, the container doors are properly closed, and the lead seal is properly locked, it proves that the container has not been opened without authorization during transport. The contents of the container are the responsibility of the person loading the container during loading. With the development of technology and the advancement of anti-theft technology, existing… Anti-theft lead seals are constantly being improved. Nowadays, manufacturers have integrated circuit modules into the lead seals, making them more intelligent. By marking a QR code on the lead seal and connecting it to the cloud, people can simply scan the QR code to determine the overall data of the lead seal, preventing unauthorized replacement. At the same time, manufacturers have integrated RFID modules into the anti-theft lead seals, making their use traceable and enabling reuse. Even now, lead seals remain the best choice for locking in transportation, and their production cost is relatively low, making them widely used in various fields. However, existing anti-theft lead seals have certain drawbacks in inspection. Due to the integration of many modules, anti-theft lead seals are relatively fragile, and the yield rate of production is also reduced. Therefore, after production, anti-theft lead seals should be inspected to check whether the QR code is missing, whether the metal wire on the surface is broken, and whether the RFID module is functioning properly. Currently, such inspection operations mostly require manual processing. People observe the quality of the anti-theft lead seals with the naked eye and record it, which greatly increases the labor costs of enterprises. In addition, the efficiency of manual inspection is relatively low, and personnel often make mistakes during inspection. Visual inspection is also full of limitations. Therefore, we propose a high-efficiency inspection device for anti-theft lead seals. Summary of the Invention

The second telescopic rod sleeve is movably installed on the side surface of the first threaded rod through the threaded groove. The second telescopic support rod is movably installed inside the upper part of the second telescopic rod sleeve. The second hydraulic pump is fixedly installed on the upper end surface of the second telescopic support rod. The second hydraulic pump is fixedly installed on the upper surface of the transverse shaft frame near both ends. The second threaded rod is fixedly installed inside the transverse shaft frame, and the side surface of the second threaded rod is provided with meshing patterns.

[0010] Preferably, a second motor is fixedly installed inside the movable displacement block near the upper surface. The second motor is connected to a power supply. A movable shaft is movably installed on the output end surface of the second motor. A helical gear is sleeved on the side surface of the portion of the movable shaft inside the transverse shaft frame. The side surface of the helical gear is provided with meshing patterns.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the workbench is moved by the universal wheels in conjunction with the No. 1 telescopic rod sleeve, and then moved to the assembly line with the anti-theft lead seal. The workbench is connected to the power supply, and the No. 1 hydraulic pump controls the No. 1 telescopic support rod to move up and down in the No. 1 telescopic rod sleeve, thereby adjusting the horizontal height of the workbench. This completes the seamless connection between the conveyor belt and the assembly line, making it convenient for workers to assemble. Through the close cooperation of components such as the horizontal and vertical shafts, employees can easily manipulate the movable displacement block to move at any coordinate inside the inspection box, thereby controlling the shooting position of the camera device. Once the camera device finds the appropriate position, it can detect whether the QR code on the anti-theft seal is missing, using the camera device and supplementary lighting. After detecting the QR code, the distance between the camera device and the anti-theft seal is further reduced. At this time, the No. 4 motor drives the movable shaft column to rotate, switching to electron microscope mode to carefully observe whether there are any defects on the surface of the anti-theft seal. At the same time, the eddy current effect of the eddy current flaw detector is used to detect the quality of the anti-theft seal, strictly controlling the pass rate of production. After the above inspection is completed, the conveyor belt carries the anti-theft seal away from the inspection box. The RFID reader detects the RFID reading and writing performance of the anti-theft seal and matches it with the cloud data, thus completing the inspection process, greatly reducing manual labor and liberating productivity.

[0019] It should be noted that this invention is a high-efficiency detection device for anti-theft lead seals. In use, the workbench 1 is first moved by the universal wheels 104 in conjunction with the first telescopic rod sleeve 103, placing it on the anti-theft lead seal production line. Then, the workbench 1 is connected to a power source, and the first telescopic support rod 102 is controlled by the first hydraulic pump 101 to move up and down within the first telescopic rod sleeve 103, thus adjusting the horizontal height of the workbench 1. This achieves a seamless connection between the conveyor belt 3 and the production line, facilitating assembly by workers. After production, the anti-theft lead seals enter the detection box 2 through the inlet 201 via the conveyor belt 3. At this point, the movement of the conveyor belt 3 is stopped. By controlling the rotation of motor 9, the camera 903 is positioned vertically and horizontally to capture images. The camera 903, in conjunction with the supplementary light 904, transmits images of the inside of the detection box 2, which are then displayed on the control panel 204 and display screen 203 for easy operation. Motor 401 controls the rotation of the first threaded rod 402. Because the lower end of the second telescopic sleeve 5 has a threaded rod groove, and the threads on the inner wall of the groove mesh with the threads on the side surface of the first threaded rod 402, the rotation of the first threaded rod 402 allows the second telescopic sleeve 5 to move within the vertical shaft frame 4. The second hydraulic pump 502 drives the second telescopic sleeve... The strut 501 moves up and down inside the second telescopic sleeve 5, thereby controlling the horizontal height of the transverse shaft 6. The second motor 701 drives the movable shaft 702 to rotate. Because the meshing patterns on the side surface of the helical gear 703 mesh with the meshing patterns on the side surface of the second lead screw 601, the movable displacement block 7 can move freely on the transverse shaft 6. Through the above operations, employees can easily manipulate the movable displacement block 7 to move at any coordinate inside the detection box 2, thereby controlling the shooting position of the camera device 903. Once the camera device 903 has found the appropriate position, it works in conjunction with a supplementary light. 904 can detect whether the QR code on the anti-theft lead seal is missing. After detecting the QR code, the camera device 903 is brought closer to the anti-theft lead seal. At this time, the fourth motor 9 drives the movable shaft 901 to rotate, switching to the electron microscope 902 mode to carefully observe whether there are any defects on the surface of the anti-theft lead seal. At the same time, the eddy current effect of the eddy current flaw detector 301 is used to detect the quality of the anti-theft lead seal, strictly controlling the production pass rate. After the above detection is completed, the conveyor belt 3 carries the anti-theft lead seal away from the detection box 2. The RFID reader 302 detects the RFID reading and writing performance of the anti-theft lead seal and matches it with the cloud data, thereby completing the detection process.
