[0002] In the field of trace explosive detection, sampling carrier (test strip) sampling and detection technology has been widely used due to its advantages such as ease of operation and rapid detection. Currently, the detection process of trace explosive sampling test strips usually includes multiple steps such as test strip placement, sample application, detection, and test strip recovery. To improve detection efficiency, continuous test strip detection has become a key requirement, and continuous sample application is an important part of this process.

[0003] Existing trace explosive sampling test strip delivery devices have many shortcomings in achieving continuous test strip dispensing. For example, during continuous delivery of test strips, the test strips may shift in position due to movement, which may prevent the dispensing device from effectively dispensing the test strips.

[0027] like Figures 1-4 As shown, this embodiment provides a conveying device for a sampling carrier of a security inspection equipment, including: a workbench 10, a rotating table 20, multiple pressure plates 30, and a lifting assembly 40. The rotating table 20 is rotatably connected to the workbench 10. The top surface of the rotating table 20 is provided with multiple working positions distributed circumferentially. Each pressure plate 30 corresponds to one working position. The pressure plate 30 is rotatably connected to the rotating table 20. The pressure plate 30 rotates and cooperates with the rotating table 20 to press the sampling carrier firmly at the working position. The lifting assembly 40 is connected to the workbench 10. The lifting assembly 40 is provided with a lifting part. The lifting part moves toward the pressure plate 30 to drive the pressure plate 30 to rotate.

[0028] In some embodiments, the workbench 10 serves as the basic support structure of the entire conveying device, providing a stable operating platform. The rotating table 20 is rotatably connected to the workbench 10 and can rotate on the workbench 10. The top surface of the rotating table 20 is provided with multiple working positions distributed circumferentially, each used to place a sampling carrier (test strip). Each pressure plate 30 corresponds to one working position and is rotatably connected to the rotating table 20. The function of the pressure plate 30 is to cooperate with the rotating table 20 to press the test strip firmly onto the working position, ensuring the stability of the test strip during the conveying process. The lifting assembly 40 is connected to the workbench 10 and is provided with a lifting part. The lifting part can move toward the pressure plate 30. Through contact and drive with the pressure plate 30, the lifting part causes the pressure plate 30 to rotate, thereby controlling the pressing and releasing of the test strip.

[0029] In some embodiments, the rotary table 20 can rotate on the worktable 10 to sequentially convey test strips from different workstations to designated operating positions. The conveying device is equipped with a paper placement position, a sampling position, and a paper collection position. When the conveying device is in operation, when a workstation rotates to face the paper placement position, the lifting component 40 operates to move the lifting part towards the pressure plate 30 and drive the pressure plate 30 to rotate. At this time, the workstation is fully open, and the test strip can be placed in the workstation. As the rotary table 20 rotates, the test strips on the workstation can be conveyed. When the workstation with the test strip placed rotates to face the sampling position, the test strip can be sampled. The sampled test strip continues to be conveyed until it faces the paper collection position. At this time, the lifting component 40 operates to drive the pressure plate 30 to rotate, and the pressure plate 30 fully opens the workstation to facilitate test strip removal. This process is repeated to achieve continuous transport and sampling of the test strips, improving the sampling efficiency.

[0030] It is worth mentioning that when it is necessary to place or remove the test strip, the lifting part of the lifting component 40 moves toward the pressure plate 30, driving the pressure plate 30 to rotate, thereby opening the working position and facilitating the placement or removal of the test strip. After the test strip is placed, the lifting component 40 resets, and the pressure plate 30, under its own weight or the action of a spring or other reset mechanism, presses the test strip again to ensure the stability of the test strip during the transmission process.

[0031] According to the present invention, the sampling carrier conveying device for security inspection equipment achieves continuous conveying and sampling of the sampling carrier by rotating the rotating table 20 relative to the worktable 10, thereby improving the sampling efficiency of the sampling carrier. Moreover, the sampling carrier is pressed by the cooperation of the pressure plate 30 and the rotating table 20, thus achieving stable conveying of the sampling carrier. At the same time, by setting a lifting component on the worktable 10, the lifting component 40 can drive the pressure plate 30 to rotate so that the working position is fully opened, thereby facilitating the paper feeding and receiving work, and further improving the sampling efficiency of the sampling carrier.

[0032] According to some embodiments of the present invention, the workbench 10 is provided with paper placement positions, sample placement positions and paper collection positions spaced apart in the circumferential direction. Both the paper placement positions and the paper collection positions are provided with lifting components 40. When the workbench is rotated to be directly opposite the sample placement position, the sample placement device is adapted to place the sample carrier on the workbench directly opposite the sample placement position.

[0033] In some embodiments, both the paper feeding position and the paper receiving position are provided with lifting components 40. When the working position rotates to be directly opposite the paper feeding position and the paper receiving position, the lifting components 40 work to drive the pressure plate 30 to rotate, thereby fully opening the working position directly opposite the paper feeding position and the paper receiving position, thus facilitating the paper feeding and paper receiving operations.

[0034] According to some embodiments of the present invention, the lifting assembly 40 includes a cylinder 41, the cylinder 41 having a piston rod adapted to move in the height direction, and a top rod 42 is provided on the top of the piston rod as a lifting part, the top rod 42 moves and cooperates with the pressure plate 30 to drive the pressure plate 30 to rotate.

[0035] In some embodiments, when it is necessary to drive the pressure plate 30 to rotate, the cylinder 41 starts to work. The piston rod of the cylinder 41 moves in the height direction under the action of air pressure. As the piston rod moves, the push rod 42 provided at the top of the piston rod also moves. The direction of movement of the push rod 42 is towards the pressure plate 30. The push rod 42 moves to contact the pressure plate 30 and generates a force to drive the pressure plate 30 to rotate around its connection point with the rotating table 20.

[0036] Understandably, the cylinder 41, as a power source, has the characteristics of simple structure, stable operation and high reliability, which enables the lifting assembly 40 to maintain stable performance during long-term and high-frequency operation. Moreover, through the precise control of the cylinder 41 and the piston rod, the moving distance and speed of the push rod 42 can be precisely adjusted, thereby precisely controlling the rotation angle and timing of the pressure plate 30.

[0037] According to some embodiments of the present invention, a rotating rod 21 is provided on the rotating table 20, and the pressure plate 30 is rotatably connected to the rotating rod 21 through a connecting lug. A torsion spring is sleeved on the outer periphery of the rotating rod 21, one end of the torsion spring is engaged with the rotating table 20, and the other end of the torsion spring is engaged with the pressure plate 30.

[0038] In some embodiments, when the push rod 42 of the lifting assembly 40 moves toward the pressure plate 30, the push rod 42 contacts the pressure plate 30 and generates a force to drive the pressure plate 30 to rotate around the rotating rod 21. During the rotation of the pressure plate 30, the torsion spring is compressed or stretched, thereby storing elastic potential energy. When the push rod 42 of the lifting assembly 40 retracts, the torsion spring releases the stored elastic potential energy, applying a torque opposite to the direction of rotation to the pressure plate 30, causing the pressure plate 30 to automatically return to its initial position and re-press the test paper on the working position.

[0039] Therefore, by setting the torsion spring, the pressure plate 30 can automatically reset after rotating under the action of the lifting component 40, without the need for an additional drive mechanism or manual intervention. Moreover, the reset force provided by the torsion spring ensures that the pressure plate 30 can stably press the test paper on the working position after resetting, preventing the test paper from moving or falling off during the transmission process.

[0040] According to some embodiments of the present invention, the pressure plate 30 protrudes radially from the rotating table 20, and the portion of the pressure plate 30 protruding from the rotating table 20 is rotatably provided with a roller 31, which is adapted to cooperate with the top rod 42.

[0041] In some embodiments, by providing rollers 31, the contact between the push rod 42 and the pressure plate 30 changes from sliding contact to rolling contact, thereby reducing friction and wear, improving the service life and reliability of the pressure plate 30 and the push rod 42, and thus extending the service life of the conveying device.

[0042] It is worth mentioning that rolling contact has less frictional resistance than sliding contact, thus improving the transmission efficiency of the push rod 42 driving the pressure plate 30 to rotate. At the same time, due to the presence of the roller 31, the cooperation between the push rod 42 and the pressure plate 30 is smoother, reducing jamming and vibration, and optimizing the operating experience.

[0043] According to some embodiments of the present invention, one working position corresponds to two pressure plates 30, and the two pressure plates 30 are respectively disposed on both sides of the working position in the circumferential direction.

[0044] In some embodiments, when the test strip is placed on the working position, the line connecting the center of the test strip to the center of the rotating table 20 is perpendicular to the extension direction of the test strip. Thus, the two pressure plates 30 can press the two ends of the test strip respectively, thereby making the test strip more stably fixed on the rotating table 20, and thus making the transmission of the test strip more stable.

[0045] According to some embodiments of the present invention, in the two pressure plates 30 corresponding to a working position, the distance between the two pressure plates 30 is equal in the radial direction, and the working position includes a plurality of placement positions 23 spaced apart in the radial direction, each placement position 23 being suitable for placing a sampling carrier.

[0046] It is understandable that, through the above settings, after multiple test strips are placed in the working position, the multiple test strips are distributed radially at intervals along the rotating table 20, and after the two pressure plates 30 corresponding to the working position press the multiple test strips on the placement position 23 respectively, the test strips on each placement position 23 are pressed in the same position by the pressure plate 30.

[0047] Therefore, when the working position is rotated to face the paper placement position, multiple test strips can be placed at once, and when the working position is rotated to face the sample placement position, multiple test strips can be sampled at once. At the same time, when the working position is rotated to face the paper collection position, multiple test strips can be collected at once.

[0048] According to some embodiments of the present invention, a sector plate 22 is provided between adjacent working positions. The sector plate 22 is connected to the rotating table 20. Pressure plates 30 are rotatably connected to both sides of the sector plate 22 in the radial direction.

[0049] It is understandable that the sector plate 22 is rotatably connected to the pressure plate 30 on both sides in the circumferential direction. The setting of the sector plate 22 can make up for the angle problem between adjacent pressure plates 30. That is, after setting the sector plate 22, the angle of the pressure plate 30 does not need to be considered when making the pressure plate 30, so that the pressure plate 30 is presented in a rectangular structure, which facilitates the manufacturing of the pressure plate 30.

[0050] According to some embodiments of this utility model, the surface of the working station is provided with an epoxy resin coating. It is understood that the smooth surface of the epoxy resin coating reduces the risk of wear and tear on the test strip during placement and transport, reduces damage to the test strip caused by friction, scratching, etc., and ensures the integrity of the test strip, thereby improving the reliability of subsequent testing. Furthermore, the chemical stability of the epoxy resin coating effectively prevents chemical reactions between the working station surface and the test strip sample, avoiding sample contamination and ensuring that the test results accurately reflect the explosive residue on the test strip, thus improving the accuracy of the test.

[0051] According to some embodiments of the present invention, the conveying device further includes a housing 50, which is disposed on the top of the worktable 10, and the housing 50 and the worktable 10 together define a receiving cavity suitable for accommodating the rotating table 20, and the side wall of the worktable 10 is provided with a working opening suitable for communicating the receiving cavity with the outside.

[0052] In some embodiments, the cavity formed by the housing 50 and the worktable 10 can effectively block external dust, impurities, etc. from entering the interior of the conveying device, preventing foreign objects from adhering to the rotating table 20, test strips, and other components, thus affecting the detection accuracy of the test strips and the normal operation of the device. Moreover, to a certain extent, the cavity can also play a safety protection role, preventing operators from accidentally contacting the moving parts inside the device (such as the rotating table 20), thus reducing the safety risks during operation.

[0053] It should be noted that the housing 50 is provided with three working ports, which are respectively opposite to the sample dispensing position, the paper feeding position, and the paper receiving position. This allows the paper feeding arm to enter the receiving cavity through the working port opposite to the paper feeding position to place the test paper to be sampled in the working position; and allows the sample dispensing arm to enter the receiving cavity through the working port opposite to the sample dispensing position to dispense the test paper; and allows the paper taking arm to enter the receiving cavity through the working port opposite to the paper taking position to take out the sampled test paper.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
