[0026] like Figures 1-3As shown, this embodiment provides a sampling test strip collection device for trace explosives, including: a workbench 10, a paper suction arm 21, a transfer arm 22, and a clamping arm 23. The workbench 10 is provided with a first station 11 and a second station spaced apart along its own length. The paper suction arm 21 is movably connected to the workbench 10. The paper suction arm 21 moves to move multiple test strips that have been sampled to the first station 11 at the same time. The transfer arm 22 is movably connected to the workbench 10. The transfer arm 22 is adapted to move multiple test strips to the second station and stack them. The clamping arm 23 is adapted to transfer the multiple test strips stacked at the second station to a packaging bag.

[0027] In some embodiments, the workbench 10 is provided with a first station 11 and a second station spaced apart along its length. The first station 11 and the second station provide specific operating areas for the collection and stacking of test strips. The suction arm 21 is movably connected to the workbench 10 and can move on the workbench 10. The movement of the suction arm 21 can move multiple test strips that have been sampled to the first station 11 at the same time. The transfer arm 22 is also movably connected to the workbench 10. The movement of the transfer arm 22 can move multiple test strips on the first station 11 to the second station for stacking, thereby completing the transfer of test strips from the first station 11 to the second station. The clamping arm 23 is also movably connected to the workbench 10. The movement of the clamping arm 23 can transfer multiple test strips that have been stacked on the second station to the packaging bag as a whole, completing the last step of the test strip collection operation.

[0028] It is understood that the suction arm 21, transfer arm 22, and clamping arm 23 are connected to the worktable 10 via driving components, which can be cylinders, motors, hydraulic cylinders, or screw mechanisms, etc., without limitation. Upon receiving a control signal, the suction arm 21 moves to the location of the sampled test strips. Using its own adsorption device (such as a suction cup), the suction arm 21 simultaneously adsorbs multiple test strips and then accurately and stably places them on the first station 11 of the worktable 10 according to a preset movement path. After the suction arm 21 completes the placement of the test strips, the transfer arm 22 begins operation, sequentially moving the multiple test strips from the first station 11 to the second station, stacking them one by one. Once the test strips are stacked on the second station, the clamping arm 23 begins operation. Using a specific clamping structure, the clamping arm 23 clamps the stacked test strips from both sides, transferring the entire stack of test strips into a packaging bag in one go, completing the collection and packaging of the test strips.

[0029] According to the present invention, the sampling test strip collection device for trace explosives achieves rapid and continuous collection of test strips from the completion of sampling to the packaging bag through the automated coordinated work of the suction arm 21, the transfer arm 22 and the clamping arm 23, which improves the efficiency of test strip collection, reduces manual intervention and lowers labor costs. At the same time, it avoids direct contact between the personnel and the trace explosives sampling test strips, reduces the risk of operators coming into contact with harmful substances and ensures the safety of operators.

[0030] It is worth mentioning that the collection device of this application can achieve stable and accurate test strip collection, which helps to ensure the integrity and quality of the test strips during the collection and packaging process, reduce test strip damage or contamination caused by human factors, and thus improve the quality of the final product.

[0031] According to some embodiments of the present invention, the workbench 10 is further provided with a flip position 13, which is located between the first work station 11 and the second work station. The workbench 10 is rotatably and movably connected to a flip gripper 24. The transfer arm 22 is adapted to transfer the test paper of the first work station 11 to the flip position 13, and then transfer the test paper of the flip position 13 to the second work station. The flip gripper 24 is adapted to flip the test paper of the flip position 13.

[0032] In some embodiments, the flipping gripper 24 moves toward the flipping position 13 and clamps the test paper on the flipping position 13. Then, the flipping gripper 24 moves and resets. Next, the flipping gripper 24 rotates to flip the test paper. Then, the flipping gripper 24 moves and moves the flipped test paper to the flipping position 13. Finally, the flipping gripper 24 resets to wait for the next flipping operation.

[0033] In other embodiments, a flipping position 13 is provided on the workbench 10 between the first station 11 and the second station. The flipping position 13 can provide a dedicated area for the flipping operation of the test strip, avoiding interference between the flipping operation and the operation of other stations, and ensuring the orderly progress of the entire collection process.

[0034] The flipping gripper 24 is rotatably and movably connected to the worktable 10. The flipping gripper 24 can move on the worktable 10 to accurately reach the test paper position on the flipping position 13, and it can also rotate to flip the test paper. After the transfer arm 22 places the test paper on the flipping position 13, the flipping gripper 24 moves to the appropriate position and clamps the test paper, and then completes the flipping action of the test paper through its own rotation mechanism.

[0035] Understandably, the clamping arm 23 can transfer multiple stacked test strips to the packaging bag. These stacked test strips constitute a sample set. Within a sample set, the transfer arm 22 is adapted to transfer the last test strip from the first station 11 to the flipping station 13, and then transfer the test strip from the flipping station 13 to the second station. Thus, this arrangement allows the top layer of the sample set to be flipped, ensuring the sample on the top layer faces the worktable 10. This prevents the sample from contacting the packaging bag after the sample set is placed inside, thus avoiding sample contamination or damage to the packaging bag.

[0036] Therefore, the setting of the flip position 13 and the flip gripper 24 enables the collection device to meet the need to flip the test strip. In the field of trace explosive detection, it can avoid direct contact between the sample on the test strip and the packaging bag, prevent the sample from being contaminated or the packaging bag from being damaged, thereby ensuring the accuracy and reliability of the test results.

[0037] It is worth mentioning that the transfer arm 22 operates according to the transfer path described in this application, making the entire test strip collection process more rational and efficient. After the initial transfer of the test strips is completed, necessary flipping can be performed at the flipping station 13 before the strips are transferred to the second station for stacking. The entire process is smooth and orderly, reducing unnecessary operational steps and wasted time. Moreover, the automated flipping operation reduces human intervention, lowers the risk of operators coming into contact with test strips and potentially harmful substances, and avoids operational errors and safety hazards that may arise from manual flipping, ensuring operator safety and production stability.

[0038] According to some embodiments of the present invention, the workbench 10 is provided with an anti-contact groove 131, which is located at the flip position 13 and is directly opposite to the spotting position of the test paper.

[0039] In some embodiments, the anti-contact groove 131 effectively prevents the test strip spotting location from contacting the worktable 10 after flipping, preventing sample contamination and thus ensuring the accuracy and reliability of trace explosive detection results. In trace detection, even minute contamination can lead to deviations in detection results; the anti-contact groove 131 reduces this risk.

[0040] Furthermore, avoiding contact between the sample and the workbench 10 reduces the occurrence of test failures or repeated tests due to sample contamination, improves the overall operating efficiency and reliability of the collection device, and enables the collection device to complete the test strip collection and testing tasks more stably, reducing the probability of malfunctions.

[0041] It is worth mentioning that, in addition to preventing sample contamination, the anti-contact groove 131 can also protect the integrity of the test strip to a certain extent. Specifically, during the flipping operation, the anti-contact groove 131 avoids unnecessary squeezing or friction on the test strip spotting position, preventing the test strip from being damaged and further ensuring the smooth progress of the test.

[0042] According to some embodiments of the present invention, the workbench 10 is further provided with a flipping groove 132 that extends through its own thickness direction. The flipping groove 132 extends to one side of the workbench 10 in the width direction, and at least a portion of the flipping gripper 24 is rotatably disposed in the flipping groove 132.

[0043] In some embodiments, the flipping gripper 24 includes a first gripper and a second gripper, which rotate relative to each other to clamp the test strip, and at least a portion of the first gripper and the second gripper are rotatably disposed within the flipping groove 132.

[0044] It is understood that the flipping groove 132 extends in the width direction of the worktable 10, and extends to one side of the worktable 10 in the width direction, and the portion of the test paper projected in the height direction of the worktable 10 overlaps with the flipping groove 132. Thus, during flipping, the first claw and the second claw move to both sides of the test paper in the thickness direction, respectively, and then the first claw and the second claw rotate relative to each other to clamp the test paper.

[0045] Thus, through the above-mentioned configuration, the flip groove 132 provides a suitable rotation space for the flip gripper 24, enabling the flip gripper 24 to stably and accurately complete the clamping action of the test paper.

[0046] According to some embodiments of the present invention, the first station 11 includes multiple placement positions, and each placement position and flipping position 13 is provided with a suction port 14, which is connected to a suction device.

[0047] In some embodiments, the first station 11 is provided with multiple placement positions to meet the need to place multiple pre-diffused test strips simultaneously. Each placement position and flipping position 13 is provided with a suction port 14, which is connected to an air suction device. The negative pressure adsorption generated by the suction port 14 effectively fixes the position of the test strip on the placement position and flipping position 13, preventing the test strip from moving or falling due to vibration, airflow, or other factors during the operation of the collection device. This improves the operational stability of the entire collection device and reduces operational errors and malfunctions caused by test strip position deviations.

[0048] It is worth mentioning that, since the test strips are accurately adsorbed and fixed at each station, the transfer arm 22 can more accurately position and grab the test strips during the process of transferring the test strips from the first station 11 to the flipping station 13 and then from the flipping station 13 to the second station. This reduces the problem of grabbing failure or placement deviation caused by the uncertain position of the test strips, and ensures the accuracy of test strip collection and stacking.

[0049] According to some embodiments of the present invention, the second work station is constructed as a temporary storage groove 12 extending in the thickness direction of the worktable 10, and the temporary storage groove 12 extends to one side of the worktable 10 in the width direction.

[0050] In some embodiments, the temporary storage tank 12 extends in the thickness direction of the workbench 10 to provide sufficient vertical space for the stacking of test strips. During the test strip collection process, multiple test strips need to be stacked sequentially on the second station. The extension design in the thickness direction allows the temporary storage tank 12 to accommodate a certain number of test strip stacks without causing the test strips to be stacked too high or unstable due to space limitations.

[0051] Of course, the temporary storage tank 12 extends to one side of the workbench 10 in the width direction. On the one hand, this facilitates the transfer of the stacked test strips from the temporary storage tank 12 by the clamping arm 23. Specifically, the clamping arm 23 can enter the temporary storage tank 12 from one side of the workbench 10 to easily clamp the stack of test strips. On the other hand, it also facilitates the cleaning, maintenance, and observation of the test strip stacking in the temporary storage tank 12. During the operation of the collection device, the staff can more easily check the stacking status of the test strips in the temporary storage tank 12 from one side of the workbench 10, and promptly detect and handle any abnormalities.

[0052] According to some embodiments of the present invention, the workbench 10 is provided with a guide groove 121, which surrounds the outer periphery of the temporary storage groove 12, and the cross section of the guide groove 121 gradually decreases in the direction toward the temporary storage groove 12.

[0053] In some embodiments, a guide groove 121 is provided around the outer periphery of the temporary storage tank 12. The guide groove 121 provides a guiding path for the test strip entering the area of ​​the temporary storage tank 12. When the test strip is transferred from other stations to the second station (temporary storage tank 12), due to possible errors in mechanical movement or the influence of external factors (such as airflow or slight vibration), the test strip may not fall accurately directly into the temporary storage tank 12. The guide groove 121 surrounds the temporary storage tank 12, and no matter which direction the test strip approaches the area of ​​the temporary storage tank 12 from, it can be "captured" by the guide groove 121 and guided to move towards the temporary storage tank 12.

[0054] The cross-section of the guide groove 121 gradually decreases in the direction toward the temporary storage groove 12, forming a funnel-like structure. As the test strip enters the guide groove 121, its movement within the groove gradually becomes restricted due to the continuously decreasing cross-section. Consequently, the constraint force exerted by the sidewall of the guide groove 121 gradually increases. This constraint force guides the test strip along the direction of the guide groove 121, ultimately ensuring that the test strips are accurately stacked within the temporary storage groove 12.

[0055] According to some embodiments of the present invention, the bottom of the temporary storage groove 12 is provided with a clamping groove 122 that extends through in the thickness direction, and the clamping groove 122 extends to one side of the worktable 10 in the width direction.

[0056] In some embodiments, the clamping arm 23 is provided with a third claw and a fourth claw, which rotate relative to each other to clamp a plurality of stacked test strips. At least a portion of the projection of the test strip disposed in the temporary storage groove 12 in the height direction overlaps with the clamping groove 122, and portions of the third claw and the fourth claw are rotatably disposed within the clamping groove 122.

[0057] During operation, the clamping arm 23 moves so that the third and fourth claws are respectively positioned on both sides of the stacked test strips in the thickness direction. Then the third and fourth claws rotate to clamp the stacked test strips. Subsequently, the clamping arm 23 moves to transfer the stacked test strips to the packaging bag.

[0058] Therefore, the clamping slot 122 can prevent the workbench 10 from obstructing the clamping of the test paper, so that the clamping arm 23 can conveniently and quickly clamp multiple stacked test papers, thereby improving the bagging efficiency of the test paper.

[0059] According to some embodiments of the present invention, the temporary storage slots 12 are configured as a plurality of slots spaced apart in the length direction, and the plurality of temporary storage slots 12 are respectively suitable for placing test strips of different types.

[0060] In some embodiments, multiple temporary storage slots 12 are spaced apart along the length direction, mainly to make full use of the space of the workbench 10 and to achieve classified storage of different types of test strips. The spaced arrangement of multiple temporary storage slots 12 can avoid mutual interference between the slots. For example, during the transfer of test strips, test strips in different temporary storage slots 12 will not collide or get mixed up due to the space being too tight.

[0061] Of course, different types of test strips have different sizes, shapes, or materials, and their storage requirements may also differ. By setting up multiple temporary storage slots 12 to hold different types of test strips, suitable storage space and conditions can be provided for each type of test strip according to its characteristics. For example, for larger test strips, a relatively larger temporary storage slot 12 can be selected; for test strips with higher requirements for the storage environment, corresponding protective measures can be taken, such as adding moisture-proof and dust-proof structures.

[0062] According to some embodiments of the present invention, the collection device further includes a test strip sensor 25, which is disposed between the first station 11 and the second station and is adapted to sense the test strip that moves from the first station 11 to the second station.

[0063] In some embodiments, the test strip sensor 25 typically senses the presence of the test strip based on some physical or chemical principle, such as photoelectric sensing, capacitive sensing, etc., which is not limited here. The arrangement of the test strip sensor 25 enables the collection device to achieve automated test strip detection and process control. When the test strip sensor 25 senses that the test strip has moved from the first station 11 to the second station, it can transmit a signal to the control system. The control system triggers subsequent operations based on this signal, such as controlling the transfer arm 22 to stop moving, recording test strip information, or starting the next operation step, etc., reducing manual intervention and improving the automation level of the collection device.

[0064] Meanwhile, by sensing the movement of the test strip, it can be ensured that the test strip accurately reaches the second working position. If the test strip deviates during the movement or fails to reach the designated position normally, the test strip sensor 25 can detect the abnormality in time and issue an alarm to the control system or take corresponding corrective measures, avoiding problems such as uneven stacking and operation failure caused by incorrect test strip position, thus improving the accuracy of operation.

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.

[0066] 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.
