Description

Technical Field

[0001] The present application relates to the field of security inspection systems, and more specifically, to a luggage detection mechanism, a detection device, and an inspection system. Background Art

[0002] With the development of science and technology and the improvement of public safety awareness, luggage security inspection is a necessary process to check whether there are prohibited items in the luggage, such as explosives; in this way, the threat factors to public safety can be reduced, and the travel safety of people can be guaranteed.

[0003] The document with the publication (announcement) number CN111929334A discloses a security inspection device, including: a conveying component, a security inspection machine, and a trace substance detection component. The trace substance detection component is composed of one or more trace substance detection devices for wiping and sampling. The trace substance detection device for wiping and sampling may include one or more wiping and sampling points and a data processing and control module. The wiping and sampling point includes a test strip, a detection sensor, and a detection body. The test strip is strip-shaped and is fixed on the output shafts of two stepping motors on the detection body in a roll material manner. The support member props up the test strip between the output shafts of the two stepping motors. The test strip is exposed to the gap between the conveying component and the conveying device of the security inspection machine through the support member. The test strip is not lower than the conveying plane of the conveying component and the height above the conveying plane ≤ 10 mm.

[0004] When the wiping and sampling point adopts a fixed height, it will lead to insufficient sampling quality of the test strip.

[0005] Specifically, due to the different heights and sizes of the checked luggage on the conveying device, when the relatively tall and large luggage on the conveying device contacts the test strip at the wiping and sampling point, the friction force is large, while when the relatively short and small luggage on the conveying device contacts the test strip at the wiping and sampling point, the friction force is small, resulting in ineffective contact; in addition, some luggage surfaces are uneven, resulting in unstable contact between the test strip and the luggage. These two reasons jointly lead to insufficient sampling quality of the test strip. Summary of the Invention

In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0038] First, the luggage detection mechanism 100 provided by the embodiment of the present application will be described with reference to the accompanying drawings.

[0039] Refer to Figure 1 , the luggage detection mechanism 100 is used to detect whether there are prohibited items in the luggage. When in use, the luggage detection mechanism 100 can be fixed to the ground or the detection table to automatically detect the luggage. The prohibited items include but are not limited to explosives.

[0040] In this embodiment, the luggage detection mechanism 100 includes a first arm 10, a second arm 20, a swing arm 30, a first drive assembly 40, and a second drive assembly 50. The first arm 10 includes a first arm body 11, and the second arm 20 includes a second arm body 21. The second arm body 21 intersects and is movably connected to the first arm body 11. The swing arm 30 includes a swingable swing body 31. One end of the swing body 31 is slidably connected to the first arm body 11, and the other end is used for assembling and detecting a test strip for prohibited items. The first drive assembly 40 is disposed on the first arm body 11, and the second drive assembly 50 is disposed on the second arm body 21. The first drive assembly 40 is configured to drive the swing body 31 to slide left and right along the first arm body 11, and the second drive assembly 50 is configured to drive the first arm body 11 to slide up and down along the second arm body 21.

[0041] Compared with the prior art, in the luggage detection mechanism 100, when detecting luggage, the movement of the first arm body 11 and the swing body 31 is automatically controlled by the first drive assembly 40 and the second drive assembly 50, which is beneficial to improving the efficiency and inspection speed of luggage security inspection.

[0042] In one embodiment, the first arm body 11 and the second arm body are made of C-shaped groove aluminum with relatively high strength.

[0043] In one embodiment, the first arm body 11 and the second arm body 21 are perpendicularly connected to each other. It can be understood that the direction in which the first arm body 11 slides along the second arm body 21 is perpendicular to the direction in which the swing body 31 slides along the first arm body 11. When the swing body 31 is in a natural state, that is, when there is no external force causing the swing body 31 to swing, the swing body 31 is perpendicular to the first arm body 11 and parallel to the second arm body 21.

[0044] Further referring to Figure 1 , the first drive assembly 40 includes a first synchronous pulley 41, a second synchronous pulley 42, a first synchronous belt 43, a first drive device 44, and a first mounting plate 45. The first synchronous pulley 41 and the second synchronous pulley 42 are respectively fixedly connected to both ends of the first arm body 11. The first synchronous belt 43 is wound around the first synchronous pulley 41 and the second synchronous pulley 42. The first drive device 44 is connected to the first synchronous pulley 41. One side of the first mounting plate 45 is fixedly connected to the first synchronous belt 43 and is slidably connected to the first arm body 11, and the other side is fixedly connected to the swing body 31. The first drive device 44 is configured to drive the first synchronous pulley 41 to rotate to drive the first synchronous belt 43 to make a circumferential movement, thereby driving the swing body 31 connected to the first mounting plate 45 to slide left and right along the first arm body 11.

[0045] Further referring to Figure 1, the second driving assembly 50 includes a third synchronous pulley 51, a fourth synchronous pulley 52, a second synchronous belt 53, a second driving device 54 and a second mounting plate 55. The third synchronous pulley 51 and the fourth synchronous pulley 52 are respectively fixedly connected to two ends of the second arm body 21. The second synchronous belt 53 is wound around the third synchronous pulley 51 and the fourth synchronous pulley 52. The second driving device 54 is connected to the third synchronous pulley 51. One side of the second mounting plate 55 is fixedly connected to the second synchronous belt 53 and slidably connected to the second arm body 21, and the other side is fixedly connected to the first arm body 11. The second driving device 54 is configured to drive the third synchronous pulley 51 to rotate to drive the second synchronous belt 53 to make a circumferential movement, so as to drive the first arm body 11 fixedly connected to the second mounting plate 55 to slide up and down along the second arm body 21.

[0046] In this embodiment, in a rectangular coordinate system, the first arm body 11 sliding up and down along the second arm body 21 slides up and down along the axis where the Y-axis is located, and the pendulum body 31 sliding left and right along the first arm body 11 slides left and right along the axis where the X-axis is located. It can be understood that, as Figure 1 , the first arm body 11 sliding to the right slides from the second synchronous pulley 42 towards the direction close to the first synchronous pulley 41; the first arm body 11 sliding to the left slides from the first synchronous pulley 41 towards the direction close to the second synchronous pulley 42. The pendulum body 31 sliding upwards slides from the third synchronous pulley 51 towards the direction close to the fourth synchronous pulley 52, and the pendulum body 31 sliding downwards slides from the fourth synchronous pulley 52 towards the direction close to the third synchronous pulley 51.

[0047] Further referring to Figure 1 , the second arm 20 further includes two slide rails 22 which are arranged on the second arm body 21 and are oppositely arranged. The second synchronous belt 53 is located between the two slide rails 22, and the second mounting plate 55 is slidably connected to the two slide rails 22 and slides along the two slide rails 22, that is, the first arm body 11 slides up and down on the slide rails 22 of the second arm body 21 through the mounting plate. In this embodiment, the two oppositely arranged slide rails 22 are closer to the fourth synchronous pulley 52 than the third synchronous pulley 51.

[0048] In one embodiment, the first driving device 44 can be, but is not limited to, a motor, and the second driving device 54 can be, but is not limited to, a motor. The motor is a stepper motor or a servo motor.

[0049] In one embodiment, during the up-and-down sliding of the first arm body 11 along the second arm body 21, the first arm body 11 is always located between the third synchronous pulley 51 and the fourth synchronous pulley 52. During the left-and-right sliding of the pendulum body 31 along the first arm body 11, the pendulum body 31 is always located between the first synchronous pulley 41 and the second synchronous pulley 42.

[0050] Further referring to Figure 1 , a counterweight 531 is fixedly arranged on the second synchronous belt 53, and the counterweight 531 is used to reduce the driving load of the second driving device 54. Since the counterweight 531 reduces the driving load during the use of the second driving device 54, the service life of the second driving device 54 can be prolonged, and the number of component replacements and repairs of the luggage detection mechanism 100 can be reduced.

[0051] Combined with reference to Figure 2 and Figure 3 , the swing arm 30 further includes a fixed seat 32, a bearing seat 33 and a swing shaft (not shown in the figure); the fixed seat 32, the bearing seat 33 and the swing shaft are close to one end of the first arm body 11. The fixed seat 32 is fixedly connected to the first mounting plate 45, that is, the pendulum body 31 is fixedly connected to the first mounting plate 45 through the fixed seat 32. Since the first mounting plate 45 is slidably connected to the first arm body 11, the sliding connection between the pendulum body 31 and the first arm body 11 is realized, and the first pendulum body 31 can slide left and right along the first arm body 11. The fixed seat 32 and the bearing seat 33 are respectively fixedly connected to both sides of the pendulum body 31, and the swing shaft sequentially passes through the bearing seat 33, the pendulum body 31 and the fixed seat 32, and the pendulum body 31 can swing around the swing shaft.

[0052] Combined with reference to Figure 2 and Figure 4 , the luggage detection mechanism 100 further includes a unwinding assembly 70 fixedly connected to the pendulum body 31. The unwinding assembly 70 includes an unwinding member 71, a support roller 72, a sliding assembly 73 and a third driving assembly 74. The unwinding member 71 is used for winding and unwinding the test paper and is fixedly connected to the support roller 72 on one side of the pendulum body 31, and the sliding assembly 73 and the third driving assembly 74 are fixedly connected to the other side of the pendulum body 31.

[0053] In this embodiment, the vertical distance from the unwinding member 71 to the fixed seat 32 is less than the vertical distance from the support roller 72 to the fixed seat 32, the vertical distance from the support roller 72 to the fixed seat 32 is less than the vertical distance from the third driving assembly 74 to the fixed seat 32, and the vertical distance from the third driving assembly 74 to the fixed seat 32 is less than the vertical distance from the sliding assembly 73 to the fixed seat 32. The test paper for contacting the luggage is sequentially arranged on the unwinding member 71, the support roller 72, the sliding assembly 73 and the third driving assembly 74. In this embodiment, the fixed seat 32 and the sliding assembly 73 are oppositely arranged at both ends of the pendulum body 31. When the luggage detection mechanism 100 is idle (that is, when the luggage detection mechanism 100 is not in use), one end of the sliding assembly 73 is fixedly connected to the pendulum body 31 and the other end extends beyond the pendulum body 31, and the end extending beyond the pendulum body 31 can be used to arrange the test paper for contacting the luggage to be detected.

[0054] Further referring to Figure 2 and Figure 4 , the luggage detection mechanism 100 further includes a winding assembly 80 fixedly connected to the pendulum body 31. The winding assembly 80 includes a winding member 81 and a damping roller 82. The third driving assembly 74 cooperates with the damping roller 82 to wind the test paper onto the winding member 81.

[0055] In one embodiment, the third driving assembly 74 includes a third driving device 741 and a third synchronous belt 742. The damping roller 82 is used to pull the test paper to move. When the damping roller 82 pulls the test paper to move, the third driving device 741 drives the winding member 81 to wind the test paper through the third synchronous belt 742. In this embodiment, the third driving device 741 is a stepping motor or a servo motor.

[0056] Further Figure 3, the luggage detection mechanism 100 further includes an induction component 60 disposed on the swing body 31. The induction component 60 includes a torsion spring 61 sleeved on a swing shaft (not shown in the figure), a first optoelectronic bracket 62 fixedly connected to the fixed seat 32, a first optoelectronic switch 63a fixed to the swing body 31, a second optoelectronic switch 63b, and a second optoelectronic bracket 64 fixedly connected to the swing body 31. The torsion spring 61, the first optoelectronic bracket 62, the first optoelectronic switch 63a, the second optoelectronic switch 63b, and the second optoelectronic bracket 64 are located on the same side of the swing body 31. One end of the second optoelectronic bracket 64 is fixedly connected to the swing body 31 and the other end is fixedly connected to the sliding component 73. The first optoelectronic bracket 62, the second optoelectronic bracket 64, the first optoelectronic switch 63a, and the second optoelectronic switch 63b are located on the same side of the swing body 31, and the first optoelectronic bracket 62 and the first optoelectronic switch 63a cooperate to sense the swing angle of the swing body 31.

[0057] In this embodiment, the first optoelectronic bracket 62 can sense the swing angle of the swing body 31 through the first optoelectronic switch 63a. When the swing angle exceeds a preset value, the second driving component 50 drives the first arm body 11 to slide upward (that is, drives the first arm body 11 to slide away from the direction of the third synchronous pulley 51) to prevent excessive external force from damaging the first arm 10, the second arm 20, and the swing arm 30 of the luggage detection mechanism 100. In one embodiment, the preset value can be, but is not limited to, 30 degrees, and the specific size of the preset value can be designed according to actual usage conditions.

[0058] Further referring to Figure 2 and Figure 3 , the sliding component 73 includes at least one sliding member 731, a sliding shaft 732 that can movably penetrate each sliding member 731, a tension support frame 733 fixedly connected to one end of the sliding shaft 732, a spring 734 connected to the other end of the sliding shaft 732, and a blocking support frame 735. The spring 734 is fixedly connected to the swing body 31 through the blocking support frame 735; the blocking support frame 735 is closer to the fixed seat 32 than the tension support frame 733, and the second optoelectronic bracket 64 is fixedly connected to the tension support frame 733. The test paper is disposed at one end of the tension support frame 733 away from the sliding member 731 and this end is used to contact the luggage.

[0059] In this embodiment, the number of the sliding members 731, the number of the sliding shafts 732, the number of the springs 734 is 2, and the number of the blocking brackets 735 is also 2. The two sliding members 731 are fixedly connected to the same side of the swing body 31 and are arranged oppositely. Each sliding member 731 is penetrated by one of the sliding shafts 732; one end of each spring 734 is connected to one sliding shaft 732, and the other end is fixedly connected to the swing body 31 through one blocking bracket 735. The two sliding shafts 732 are both fixedly connected to the tension support frame 733.

[0060] In this embodiment, when using the luggage detection mechanism 100, when the swing arm 30 impacts the luggage, the tension support frame 733 slides upward through the sliding shaft 732 (that is, the tension support frame 733 slides in a direction away from the luggage) to compress the spring 734. When the signal of the second photoelectric switch 63b is blocked by the second photoelectric bracket 64, it is sensed at this time that the tension support frame 733 contacts the luggage. At the same time, the swing body 31 swings due to an external force. When the swing angle of the swing body 31 is greater than a preset value, the second driving assembly 50 drives the first arm body 11 to slide upward (that is, drives the first arm body 11 to slide in a direction away from the third synchronous pulley 51) to prevent excessive external force from damaging the first arm 10, the second arm 20, and the swing arm 30 of the luggage detection mechanism 100. When the external force disappears, the spring 734 returns from the compressed state to the initial state. At this time, the tension support frame 733 extends beyond the swing body 31 for subsequent detection of the luggage.

[0061] When using the luggage detection mechanism 100 to detect luggage, according to the distance between the luggage and the luggage detection mechanism 100, the second driving assembly 50 drives the first arm body 11 to slide up and down along the second arm body 21, and the first driving assembly 40 drives the swing body 31 to slide left and right along the first arm body 11. When detecting luggage, when the impact force of the luggage on the swing body 31 is too large and the sensing assembly 60 senses that the swing angle of the swing body 31 is greater than a preset value, the second driving assembly 50 drives the first arm body 11 to slide upward to drive the swing body 31 to slide upward, preventing the impact force of the luggage from damaging the detection mechanism 100.

[0062] Refer to Figure 5 , the embodiment of the present application further provides a detection device 200. The detection device 200 includes the above-mentioned luggage detection mechanism 100 and a detector 300. The luggage detection mechanism 100 is used to assemble the test paper and contact the luggage, and the detector 300 is used to detect whether the test paper arranged on the luggage detection mechanism 100 has contacted luggage containing prohibited items.

[0063] The detection device automatically conducts luggage security checks through the luggage detection mechanism 100 and the detector 300, reducing manual participation, which is conducive to improving the inspection efficiency and speed.

[0064] The embodiment of the present application further provides an inspection system. The inspection system (not shown in the figure) includes the above-mentioned detection device 200 and an inspection table (not shown in the figure). The inspection table is used to place the luggage to be inspected, and the detection device 200 is used to detect whether the luggage on the inspection table contains prohibited items.

[0065] In this embodiment, the detection device 200 includes the above-mentioned luggage detection mechanism 100 and the above-mentioned detector 300. During the use of the inspection system, the luggage detection mechanism 100 and the detector 300 can be arranged on the inspection table; or the luggage detection mechanism 100 and the detector 300 can be fixed to the ground. In this embodiment, the height of the luggage detection mechanism 100 is coordinated with the inspection table so that the luggage detection mechanism 100 can contact the luggage on the inspection table. The height of the luggage detection mechanism 100 is adapted to the height of the detector 300. The first driving component 40 and the second driving component 50 are used to make the height of the luggage detection mechanism 100 match the height of the luggage on the inspection table so that the test paper on the swing body 31 can contact the luggage. After the test paper on the luggage detection mechanism 100 contacts the luggage, the first driving component 40, the second driving component 50 and the third driving component 74 are used to control the first arm body 11 to move upward (move in the direction away from the third synchronous pulley) and the swing body 31 to move to the right (move in the direction close to the first synchronous pulley), so that the test paper is placed in the detector 300 for detection.

[0066] Compared with the prior art, the inspection system uses the detection device 200 to automatically conduct luggage security checks, reducing manual participation, which is conducive to improving the inspection efficiency and speed.

[0067] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
