[0002] With the continuous increase in air transport volume, the types of goods are becoming increasingly complex, and various magnetic materials may be present. Due to their special physical properties, magnetic materials may interfere with key components such as navigation equipment and communication systems of aircraft; in extreme cases, strong magnetic fields may cause damage or failure of internal components of electronic equipment; magnetic goods may also attract other metal objects, resulting in unstable cargo stacking and increasing safety risks during transportation. In order to scientifically evaluate the magnetic field strength of goods, the current practice is to conduct magnetic inspections on suspected magnetic goods before consignment to assess their magnetic strength. Magnetic inspection reports are an important basis for judging whether goods meet air transport requirements. With the rapid development of e-commerce goods, the goods mailed by a large number of shop owners who have joined various e-commerce platforms are very scattered, and the consigned parcels are mostly small pieces, and rarely professionally packaged with special packaging materials suitable for air transport. When filling in the name of the goods, such retail merchants often use relatively broad names such as "gifts, tools, parts", which makes it difficult to accurately describe the properties of the contents. They may contain suspected magnetic materials such as headphones, microphones, Bluetooth speakers, refrigerator magnets, etc., and it is difficult to issue a separate magnetic inspection report, which brings new challenges to the safety prevention of magnetic materials in aviation.

[0018] Example See also Figure 1-4 The present invention provides a rapid screening device for weak magnetic materials, including a conveyor belt 2, a fixed frame 1, a servo lifting module and a detection module. The detection module is arranged on the fixed frame 1, and the detection module detects the magnetic field strength of the detection material. The fixed frame 1 is arranged on the upper part of the conveyor belt 2. The conveyor belt 2 is provided with scale lines and detection marks. When the detection material is at the detection mark, the moving beam 3 starts to move.

[0019] The fixed frame 1 is provided with a movable crossbeam 3 and a bottom crossbeam 4. The bottom crossbeam 4 is provided at the lower part of the conveyor belt 2. The bottom crossbeam 4 is provided to detect the bottom magnetic field strength of the detection material. The movable crossbeam 3 is provided at the upper part of the conveyor belt 2. The movable crossbeam 3 moves on the fixed frame 1 to detect the magnetic field strength in the front and rear of the detection material, so as to ensure the comprehensiveness of the device detection and avoid omissions. Crossbeams 5 are provided inside both ends of the fixed frame 1. The crossbeam 5 is fixedly connected to the fixed frame 1. The crossbeam 5 is provided inside the movable crossbeam 3 to avoid hindering the up and down movement of the movable crossbeam 3. The crossbeam 5, the movable crossbeam 3 and the bottom crossbeam 4 are all connected to the detection module.

[0020] The detection module includes a sensor 7, and a plurality of sensors 7 are provided. The crossbeam 5, the movable crossbeam 3 and the bottom crossbeam 4 are all provided with mounting holes, and the mounting holes are connected to the sensors 7. Each sensor 7 array contains 16 sensor units, which are respectively distributed on the crossbeam 5, the bottom crossbeam 4 and the movable crossbeam 3.

[0021] The end of the fixed frame 1 is connected to the servo lifting module, which includes a servo motor 8 and a synchronous belt 12. The synchronous belt 12 is connected to the synchronous pulley 11, and the synchronous pulley 11 is connected to the reduction motor 9. The reduction motor 9 is connected to the servo motor 8. The servo motor 8 drives the synchronous belt 12 to transfer, and then drives the moving beam 3 to move up and down, which is convenient for detecting the front and rear magnetic field strength of the test material. The servo motor 8 is connected to the top of the fixed frame 1 through the mounting plate 10. The synchronous belt 12 is connected to one end of the moving frame 13 through the mounting plate 10, and the other end of the moving frame 13 is connected to the guide rail 14. The guide rail 14 is rigidly connected to the fixed frame 4, and the moving frame 13 is connected to the moving beam 3. The moving frame 13 moves on the guide rail 14 driven by the synchronous belt 12, driving the moving beam 3 to move up and down.

[0022] Tank chains 6 are provided on both ends of the fixed frame 1, and the tank chains 6 are connected to the wires. The tank chains 6 are used to organize the wires, and the cables are buried in the tank chains 6, which plays a role in stability and beauty.

[0023] A detection camera and a warning light are arranged on the upper part of the fixed frame 1. The detection camera detects the moving state of the substance to be detected. When the measured value of the substance to be detected is higher than the target value, the warning light lights up to serve as a warning.

[0024] The detection process is as follows: the system is initialized, the servo motor 8 drives the moving beam 3 to descend to the bottom, the detection camera on the fixed frame 1 detects the movement status of the goods and uploads it to the computer, when the detection material moves to a specific position, the moving beam 3 is raised, and the sensor 7 array distributed on the moving beam 3 detects the change in the magnetic field strength in front of the detection material; the detection material continues to move forward, and the sensor 7 arrays on the moving beam 3, the beam 5, and the bottom beam 4 measure the magnetic field strength around the detection material; when the detection material moves away from the specific position, the detection material stops moving, the moving beam 3 descends again and monitors the magnetic field strength behind the detection material at the same time, and each sensor 7 array transmits the collected data to the data bus, and transmits it to the computer for subsequent analysis, and compares the calculated three-dimensional space magnetic field value with the preset target value. If the calculated value is higher than the target value, the magnetic field color at that location is displayed with high contrast, the value is highlighted, and a warning light is turned on.

[0025] Therefore, the present invention adopts the above-mentioned weak magnetic material rapid screening device, the servo lifting module drives the moving beam to move, performs all-round detection of the detection material, detects the magnetic field change through the sensor, and analyzes and judges the magnetism of the detection material to improve the detection accuracy of the device, while reducing the false detection rate and missed detection rate.
