[0092] The test strip conveying mechanism provided by the embodiment of the present application will now be described in conjunction with the drawings.

[0093] Refer to Figure 1 , the test strip conveying mechanism 100 provided by the embodiment of the present application is provided with a test strip and is used for security inspection to detect whether the items carried by the person to be inspected during the security inspection process are contraband items. The test strip is used to touch the item, and subsequently, it can be determined whether the item is a contraband by detecting the test strip. The test strip conveying mechanism 100 includes an arm body 10, a unwinding assembly 20, a winding assembly 30, a driving assembly 40, and a detection probe 50.

[0094] Specifically, the unwinding assembly 20 is fixedly connected to the arm body 10 and is used for winding and unwinding the test strip. The winding assembly 30 is fixedly connected to the arm body 10. The driving assembly 40 is disposed on the arm body 10 and is connected to the winding assembly 30, and the detection probe 50 is disposed on the arm body 10; the test strip wound on the unwinding assembly 20 is sequentially movably disposed on the detection probe 50 and the winding assembly 30, and the test strip disposed on the detection probe 50 is used to contact the items carried by the person to be inspected. The driving assembly 40 is used to drive the winding assembly 30 to move so as to drive the used test strip to be wound onto the winding assembly 30, and the winding assembly 30 pulls the test strip during the winding process to drive the unwinding assembly 20 to release the test strip.

[0095] Combined with reference to Figure 1 and Figure 2, the driving assembly 40 includes a driving roller 41 penetrating and connecting the arm body 10, a driving device 42 connected to the driving roller 41, a driving wheel 43 connected to the driving roller 41, and a synchronous belt 44. The arm body 10 is located between the driving device 42 and the driving wheel 43. The driving wheel 43 and the winding assembly 30 are located on the same side of the arm body 10. The synchronous belt 44 winds around the driving wheel 43 and the winding assembly 30. The driving device 42 is used to drive the driving wheel 43 to rotate to drive the synchronous belt 44 to make a turnover movement, so as to drive the winding assembly 30 to wind the used test paper.

[0096] In this embodiment, the driving device 42 and the driving wheel 43 are located on different sides of the arm body 10. The driving device 42 can be, but is not limited to, a servo motor.

[0097] In this embodiment, the driving roller 41 is fixed to the motor shaft end of the servo motor. The driving roller 41 is connected to the motor shaft through a D-shaped hole, and there is no relative rotation between the motor shaft and the driving roller 41. The driving wheel 43 is fixedly connected to the driving roller 41. The driving wheel 43 is provided with a D-shaped hole that matches the D-shaped shaft at one end of the driving roller 41, and there is no relative rotation between the driving wheel 43 and the driving roller 41.

[0098] With reference to Figure 2 and Figure 3 , the unwinding assembly 20 includes an unwinding shaft 22 rotatably connected to the arm body 10 and a plurality of brackets fixedly arranged on the unwinding shaft 22; the plurality of brackets are used to sleeved with the test paper with a paper core. During the winding process of the winding assembly 30, the test paper is pulled to drive the rotation of the paper core with the test paper to release the test paper.

[0099] Further referring to Figure 1 , Figure 2 and Figure 3 , the unwinding assembly 20 further includes a second bearing 21 fixed to the arm body 10, an unwinding shaft 22 rotatably connected to the second bearing 21, and a plurality of brackets 23 fixedly arranged on the unwinding shaft 22. In this embodiment, the plurality of brackets 23 are used to sleeved with the test paper with a paper core. During the winding process of the winding assembly 30, the test paper is pulled to drive the rotation of the paper core with the test paper to release the test paper.

[0100] Further referring to Figure 1 and Figure 3 , the test paper transmission mechanism 100 further includes a support member 101 fixedly connected to the arm body 10. The test paper sleeved on the brackets 23 is sequentially movably arranged on the support member 101, the detection probe 50, and the winding assembly 30.

[0101] With reference to Figure 3, Figures 4(a), 4(b) and 4(c), the winding assembly 30 includes a first bearing 31 fixed to the arm body 10, a winding shaft 32 rotatably connected to the first bearing 31, a sheave 33 fixedly sleeved on the winding shaft 32, and a winding member 34 sleeved on the winding shaft 32; the sheave 33 is located between the winding member 34 and the first bearing 31; the synchronous belt 44 is wound around the sheave 33 of the winding assembly 30. In this embodiment, the synchronous belt 44 drives the sheave 33 to rotate to drive the winding shaft 32 fixedly connected to the sheave 33 to rotate, thereby driving the winding member 34 to rotate to wind the test strip onto the winding member 34.

[0102] With further reference to Figures 4(b) and 4(c), the winding assembly 30 further includes a sleeve 35 sleeved on the winding shaft 32. The sleeve 35 has elasticity and is located on the side of the sheave 33 away from the first bearing 31. The winding member 34 is sleeved on the sleeve 35 through a pin 36.

[0103] Specifically, a small notch is formed on the sleeve. To fit with a certain interference amount, when the sleeve is sleeved onto the winding shaft 32, the small notch expands slightly. At this time, due to the frictional force, there is no relative rotation between the elastic sleeve and the winding shaft 32.

[0104] With further reference Figure 2 and Figure 3 , the detection probe 50 includes a flexible member 51 that is deformable and used to place the test strip. In this embodiment, one end of the detection probe 50 is fixedly connected to the arm body 10, and the other end extends beyond the arm body 10. Specifically, the flexible member 51 extends beyond the arm body 10.

[0105] The test strip conveying mechanism 100 further includes an induction assembly 80 fixedly connected to the arm body 10. The induction assembly 80 is used to sense whether the flexible member 51 contacts the items carried by the person to be security checked. After the flexible member 51 contacts the item, the flexible member 51 deforms and shrinks. When the deformable flexible member 51 contacts the item, it will not damage or crush the item; at the same time, when the test strip conveying mechanism 100 contacts the item, the item will exert a force on the test strip conveying mechanism 100, and the flexible and deformable flexible member 51 can play a buffering role, thereby protecting the test strip conveying mechanism from being damaged.

[0106] Specifically, the induction assembly 80 includes a photoelectric bracket 81 fixedly connected to the flexible member 51 and a photoelectric switch 82. The photoelectric switch 82 is fixedly connected to the arm body 10 and the photoelectric bracket 81.

[0107] With combined reference Figure 3 and Figure 5, the detection probe 50 further includes a sliding member 52, a sliding shaft 53, and at least one compressible spring 54 fixedly connected to the arm body 10. Specifically, one end of the sliding shaft 53 is slidably connected to the sliding member 52 and the other end is fixedly connected to the flexible member 51. One end of each spring 54 is fixedly connected to the flexible member 51 and the other end is fixedly connected to the arm body 10; the side of the flexible member 51 away from the spring 54 is used to arrange the test strip. In this embodiment, each spring 54 is fixedly connected to the arm body 10 through a fixing block 55.

[0108] It can be understood that one side of the flexible member 51 is used to arrange the test strip, and the other side is provided with the sliding member 52, the sliding shaft 53, the spring 54 and the fixing block.

[0109] In this embodiment, the detection probe 50 further includes a support roller 56 and a contact roller 57 arranged on the flexible member 51. The support roller 56 and the contact roller 57 are located on the same side of the flexible member 51 and the contact roller 57 is farther from the spring 54 than the support roller 56. The support roller 56 and the contact roller 57 are used to arrange the test strip; the test strip on the unwinding assembly 20 is sequentially movably arranged on the support member 101, the support roller 56 of the detection probe 50, the contact roller 57 of the detection probe 50 and the winding assembly 30.

[0110] With reference to Figure 2 , Figure 3 and Figure 6 , the test strip conveying mechanism 100 further includes a tensioning assembly 60 and an adjustment seat 70 connected to the arm body 10. One end of the adjustment seat 70 is fixedly connected to the arm body 10 and the other end is movably connected to the tensioning assembly 60; a part of the tensioning assembly 60 is closely arranged against the driving roller 41, and the test strip is clamped between the tensioning assembly 60 and the driving roller 41. By adjusting the distance of the tensioning assembly 60 on the adjustment seat 70, the pressure of the tensioning assembly 60 on the driving roller 41 is adjusted, so as to achieve no relative sliding between the test strip and the driving roller 41.

[0111] In this embodiment, the tensioning assembly 60 is located between the winding member 34 and the detection probe 50; the test strip starts from the winding member 34 and is sequentially arranged on the detection probe 50, the tensioning assembly 60 and the winding member 34, and the test strip is clamped between the tensioning assembly 60 and the driving roller 41.

[0112] Further referring to Figure 2 , Figure 3 and Figure 6, the tensioning assembly 60 includes a connecting arm 61, a first shaft member 62, a second shaft member 63 and a torsion spring 64; one end of the first shaft member 62 penetrates and connects the connecting arm 61 and the other end connects the arm body 10, one end of the second shaft member 63 penetrates and connects the connecting arm 61 and the other end penetrates and connects the arm body 10, one end of the torsion spring 64 is fixedly connected to the end of the first shaft member 62 penetrating the connecting arm 61 and the other end is movably connected to the adjustment seat 70; the test strip is clamped between the second shaft member 63 and the driving roller 41, and the pressure of the second shaft member 63 on the driving roller 41 is adjusted by adjusting the distance of the torsion spring 64 on the adjustment seat 70.

[0113] Further, the first shaft member 62 includes a rotatable rotating shaft 621 penetrating the connecting arm 61, and the torsion spring 64 is connected to the rotating shaft 621. The second shaft member 63 includes a third bearing 632, a tensioning shaft 631 fixedly connected to one side of the third bearing 632 and a pressing shaft 633 fixedly connected to the other side of the third bearing 632. The pressing shaft 633 and the driving roller 41 are on the same side of the arm body 10.

[0114] It can be understood that the test strip is clamped between the driving roller 41 and the pressing shaft 633, and the pressure of the pressing shaft 633 on the driving roller 41 is adjusted by adjusting the distance of the torsion spring 64 on the adjustment seat 70, so that there is no relative sliding between the test strip and the driving roller 41 when the winding assembly 30 winds the test strip and the unwinding assembly 20 releases the test strip. The relative non-sliding here is beneficial to effectively controlling the advancing distance of the test strip by the motor, saving the use of the test strip, and making full use of a roll of test strip on the unwinding assembly 20.

[0115] Further referring to Figure 2 , the test strip conveying mechanism 100 further includes a test strip sensing device fixedly arranged on the arm body 10, the unwinding assembly 20 and the test strip sensing device are respectively arranged on two opposite sides of the arm body 10, and the test strip sensing device is used to detect whether the test strip wound on the unwinding assembly 20 is used up.

[0116] In one embodiment, the test strip sensing device is a diffuse reflection sensor. Specifically, a through hole penetrating the arm body 10 is formed on the arm body 10, and the light emitted by the test strip sensing device can pass through the hole. When there is still test strip on the unwinding assembly 20, the test strip sensing device can receive the light reflected by the test strip; when the test strip on the unwinding assembly 20 is continuously consumed and the test strip is almost used up, the test strip sensing device does not receive the light reflected from the test strip, indicating that the test strip can be replaced at this time.

[0117] In the test strip conveying mechanism 100, the driving component 40 is used to drive the winding component 30 to move so as to wind the used test strip onto the winding component 30. During the winding process of the winding component 30, the test strip is pulled to drive the unwinding component 20 to release the test strip. In this way, the test strip conveying mechanism 100 does not need to continuously replace the test strip, which is beneficial to improving the inspection efficiency and speed.

[0118] An embodiment of the present invention further provides a detection device, which is used to detect whether the items carried by the person to be inspected during the security inspection process have contraband items. The detection device includes a bracket, the above-mentioned test strip conveying mechanism and a detection mechanism. The test strip conveying mechanism is arranged on the bracket, and the test strip on the detection probe is used to contact the items carried by the person to be inspected; the detection mechanism is used to detect whether the test strip that has contacted the items carried by the person to be inspected has contacted contraband.

[0119] In this embodiment, when the detection device detects an item, the test strip conveying mechanism can continuously convey the test strip and does not need to continuously replace the test strip, which is beneficial to improving the inspection efficiency and speed.

[0120] Refer to Figure 7 , an embodiment of the present invention further provides a test strip conveying method. This test strip conveying method is based on the above-mentioned test strip conveying mechanism and includes the following steps:

[0121] Step S1: Sleeve the test strip with a paper core on the unwinding component;

[0122] Step S2: Wind the test strip on the unwinding component around the detection probe, the driving component and the unwinding component in sequence;

[0123] Step S3: Clamp the test strip between the driving component and a tensioning component, and adjust the pressure of the tensioning component on the driving component to ensure that there is no relative sliding between the test strip and the tensioning component;

[0124] Step S4: Use the test strip on the detection probe to contact the item to be detected;

[0125] Step S5: Use the driving wheel of the driving component to drive the synchronous belt wound on the driving wheel to rotate, so as to drive the winding component connected to the synchronous belt to wind the used test strip onto the winding component; and

[0126] Step S6: Pull the test strip to move through the winding action of the winding component to drive the unwinding component to release the test strip.

[0127] In this embodiment, steps S1 and S6 are cycled to continuously convey the test strip.

[0128] In this embodiment, the test strip conveying method can effectively and continuously convey the test strips, and the conveying method is fast and effective, which is conducive to improving the inspection speed and efficiency.
