Description

Technical Field

[0001] This utility model relates to the technical field of test strip collection devices, and more specifically, to a test strip collection assembly for sampling trace explosives. Background Technology

[0002] In public safety, counter-terrorism, and various fields involving explosives detection, trace explosives detection technology plays a crucial role. As a key consumable in this technology, the efficiency, accuracy, and safety of trace explosives sampling test strips in their collection and packaging directly impact the subsequent testing work and the overall testing efficiency and quality.

[0003] In the existing technology, the collection of trace explosive sampling test strips mainly relies on manual labor.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-8 As shown, this embodiment provides a sample collection assembly 1 for trace explosives, including: a workbench 10, a transfer arm 21, a bag-retrieving clamp, and a clamping arm 23. The workbench 10 is provided with a first station 11, a second station 12, and a third station 13. The first station 11 is suitable for placing multiple sampled test strips 2. The transfer arm 21 is movably connected to the workbench 10 and is suitable for moving the multiple test strips 2 on the first station 11 to the second station 12 for stacking. The bag-retrieving clamp is movably connected to the workbench 10 and is suitable for clamping a packaging bag 3 to the third station 13 and opening the packaging bag 3. The clamping arm 23 is suitable for transferring the multiple test strips 2 stacked on the second station 12 into the packaging bag 3.

[0032] It should be noted that the transfer arm 21, the bag-retrieving clamp, and the clamping arm 23 are connected to the worktable 10 via drive components. The drive components can be cylinders, motors, hydraulic cylinders, or lead screw mechanisms, etc., and there are no restrictions here.

[0033] In some embodiments, the workbench 10 is provided with a first station 11, a second station 12 and a third station 13. The first station 11 is used to place multiple test strips 2 that have completed the sampling operation, providing a starting position for subsequent transfer operations. The transfer arm 21 is movably connected to the workbench 10 and can move on the workbench 10 to move the multiple test strips 2 placed on the first station 11 to the second station 12 respectively, and stack the multiple test strips 2 on the second station 12 so that they can be uniformly packed into the packaging bag 3 later. The bag-removing clamp is also movably connected to the workbench 10 and can pick up the packaging bag 3 to the third station 13 and further open the packaging bag 3. The function of the clamping arm 23 is to transfer the multiple test strips 2 that have been stacked on the second station 12 to the packaging bag 3 that has been opened on the third station 13 as a whole, completing the bagging operation of the test strips 2.

[0034] Understandably, the transfer arm 21 moves on the workbench 10 to precisely position the test strip 2 on the first station 11, and then uses its own gripping or adsorption structure to remove the test strip 2 from the first station 11 and move it above the second station 12 to place the test strip 2 on the second station 12. Multiple test strips 2 are stacked on the second station 12 through multiple such operations.

[0035] The bag-removing clamp also moves on the workbench 10. After the bag-removing clamp reaches the position where the packaging bag 3 is stored, it uses a specific gripping structure (such as a clamping arm, suction cup, etc., which are not limited here) to grip the packaging bag 3 and move it to the third station 13. At the third station 13, the bag-removing clamp opens the packaging bag 3 through a specific action (such as spreading, pulling, etc., which are not limited here) to prepare for the subsequent insertion of the test strip 2.

[0036] The clamping arm 23 is adapted to clamp the multiple test strips 2 stacked on the second station 12, then move to the third station 13, and put the stacked test strips 2 into the opened packaging bag 3 to complete the bagging operation of the test strips 2.

[0037] According to the present invention, the collection component 1 for the trace explosive sampling test strip 2 realizes the automated operation of bagging the test strip 2, reduces manual intervention, shortens the collection and bagging time of the test strip 2, thereby improving production efficiency. Moreover, the automated operation avoids the errors and instabilities that may be caused by manual operation, ensures the accuracy and consistency of the test strip 2 in the transfer and bagging process, reduces problems such as damage to the test strip 2 or poor packaging caused by human factors, and guarantees product quality. At the same time, the trace explosive sampling test strip 2 has certain special characteristics. The collection component 1 of this application can reduce the opportunity for direct human contact with the test strip 2, reduce the safety risks that may be caused by improper operation, such as contamination or damage to the test strip 2, and ensure the safety and reliability of the product.

[0038] According to some embodiments of the present invention, the workbench 10 is further provided with a flip position 14, which is located between the first work station 11 and the second work station 12. The workbench 10 is rotatably and movably connected to a flipping gripper 24. The transfer arm 21 is adapted to transfer the test paper 2 of the first work station 11 to the flip position 14, and then transfer the test paper 2 of the flip position 14 to the second work station 12. The flipping gripper 24 is adapted to flip the test paper 2 placed on the flip position 14.

[0039] In some embodiments, the flipping gripper 24 moves toward the flipping position 14 and clamps the test paper 2 on the flipping position 14. Then, the flipping gripper 24 moves and resets. Next, the flipping gripper 24 rotates to flip the test paper 2. Then, the flipping gripper 24 moves and moves the flipped test paper 2 to the flipping position 14. Finally, the flipping gripper 24 resets to wait for the next flipping operation.

[0040] A flipping station 14 is set on the workbench 10 between the first station 11 and the second station 12. The flipping station 14 can provide a dedicated area for the flipping operation of the test strip 2, so as to avoid the flipping operation from interfering with the operation of other stations and ensure the orderly progress of the entire collection process.

[0041] 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 position of the test strip 2 on the flipping position 14, and the flipping gripper 24 can also rotate to flip the test strip 2. After the transfer arm 21 places the test strip 2 on the flipping position 14, the flipping gripper 24 moves to the appropriate position and clamps the test strip 2, and then completes the flipping action of the test strip 2 through its own rotation mechanism.

[0042] Understandably, the clamping arm 23 can transfer multiple stacked test strips 2 to the packaging bag 3. The multiple stacked test strips 2 constitute a sample dispensing group. In a sample dispensing group, the transfer arm 21 is adapted to transfer the last test strip 2 in the sample group from the first station 11 to the flipping station 14, and then transfer the test strip 2 from the flipping station 14 to the second station 12. Thus, through the above arrangement, the top layer of the sample dispensing group can be flipped, so that the sample of the top layer of the test strip 2 can face the worktable 10, thereby avoiding contact between the sample and the packaging bag 3 after the sample group is put into the packaging bag 3, and thus avoiding sample contamination or damage to the packaging bag 3.

[0043] Therefore, the setting of the flip position 14 and the flip gripper 24 enables the collection device to meet the requirement of flipping the test strip 2. In the field of trace explosive detection, it can prevent the sample on the test strip 2 from directly contacting the packaging bag 3, preventing the sample from being contaminated or the packaging bag 3 from being damaged, thereby ensuring the accuracy and reliability of the test results.

[0044] According to some embodiments of the present invention, the first station 11 is suitable for placing six test strips 2, with each group of three test strips 2 forming a sample group, and the transfer arm 21 is suitable for transferring the last test strip 2 of each sample group to the flipping station 14 for flipping.

[0045] Understandably, the six test strips 2 are divided into two groups of three. In trace explosive detection, it is necessary to test different types of explosives or samples of different concentrations separately. Each group of three test strips 2 corresponds to different detection parameters or sample types, so as to facilitate targeted processing and analysis of the test strips 2 later.

[0046] The last test strip 2 of each sample group is flipped over to prevent the sample of the last test strip 2 from coming into contact with the packaging bag 3, thereby avoiding sample contamination or damage to the packaging bag 3, and thus improving the accuracy and reliability of the test.

[0047] It is worth mentioning that the transfer arm 21 can identify the last test strip 2 of each sample group and accurately transfer it to the flip position 14. The transfer arm 21 is programmed in a specific way. The working process of the transfer arm 21 is as follows: in the first two transfer operations, the test strip 2 at the first station 11 can be directly transferred to the second station 12. In the last transfer operation, the transfer arm 21 first transfers the test strip 2 to the flip position 14, and then transfers the test strip 2 to the second station 12.

[0048] Preferably, the workbench 10 is provided with an anti-contact groove 141, which is located at the flip position 14 and is directly opposite the sampling position of the test paper 2. The anti-contact groove 141 effectively prevents the sampling position of the test paper 2 from contacting the workbench 10 after flipping, thus preventing the sample from being contaminated and ensuring the accuracy and reliability of the trace explosive detection results.

[0049] 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 2 collection and testing tasks more stably, reducing the probability of malfunctions.

[0050] According to some embodiments of the present invention, both the first work station 11 and the flipping position 14 are provided with suction ports 15, and the suction ports 15 are connected to the suction device.

[0051] In some embodiments, the first station 11 includes multiple placement positions, each placement position and the flipping position 14 being provided with a suction port 15, which is connected to an air suction device. The first station 11 is provided with multiple placement positions to meet the requirement of simultaneously placing multiple test strips 2 that have been sampled. Each placement position and the flipping position 14 is provided with a suction port 15, which is connected to an air suction device. The negative pressure adsorption generated by the suction port 15 effectively fixes the position of the test strip 2 on the placement position and the flipping position 14, preventing the test strip 2 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 deviations in the position of the test strip 2.

[0052] It is worth mentioning that, since the test strips 2 are accurately adsorbed and fixed at each station, the transfer arm 21 can more accurately position and grasp the test strips 2 during the process of transferring the test strips 2 from the first station 11 to the flipping station 14 and then from the flipping station 14 to the second station 12. This reduces the problem of grasping failure or placement deviation caused by the uncertain position of the test strips 2, and ensures the accuracy of test strip collection and stacking.

[0053] According to some embodiments of the present invention, the second workstation 12 is configured as a stacking groove extending in the thickness direction of the worktable 10, and the stacking groove extends to one side of the worktable 10 in the width direction.

[0054] In some embodiments, the stacking slot extends in the thickness direction of the workbench 10 to provide sufficient vertical space for the stacking of test strips 2. During the collection of test strips 2, multiple test strips 2 need to be stacked sequentially on the second station 12. The extension design in the thickness direction allows the stacking slot to accommodate a certain number of test strips 2 stacks without causing the test strips 2 to be stacked too high or unstable due to space limitations.

[0055] Of course, the stacking slot 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 2 from the stacking slot by the clamping arm 23. Specifically, the clamping arm 23 can enter the stacking slot 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 stacking status of the test strips 2 in the stacking slot. During the operation of the collection device, the staff can more easily check the stacking status of the test strips 2 in the stacking slot from one side of the workbench 10, and promptly detect and handle any abnormalities that may occur.

[0056] Preferably, a guide groove 121 is provided around the outer periphery of the stacking slot, which provides a guiding path for the test strip 2 to enter the stacking slot area. When the test strip 2 is transferred from other stations to the second station 12 (stacking slot), due to potential errors in mechanical movement or external factors (such as airflow or slight vibration), the test strip 2 may not fall accurately directly into the stacking slot. The guide groove 121 surrounds the stacking slot, ensuring that the test strip 2 is "captured" by the guide groove 121 regardless of which direction it approaches the stacking slot area, guiding the test strip 2 towards the stacking slot.

[0057] The cross-section of the guide groove 121 gradually decreases in the direction towards the stacking groove to form a funnel-like structure. When the test strip 2 enters the guide groove 121, as it moves within the guide groove 121, the cross-section continuously shrinks, gradually restricting the movement space of the test strip 2. Consequently, the constraint force exerted by the side wall of the guide groove 121 gradually increases. This constraint force guides the test strip 2 along the direction of the guide groove 121, ultimately ensuring that the test strip 2 is accurately stacked within the stacking groove.

[0058] According to some embodiments of this utility model, the collecting component 1 further includes a bagging box 30, which is connected to the workbench 10. The bottom of the bagging box 30 is provided with a bag-removing opening 311. It can be understood that the bagging box 30 is used to store the packaging bag 3, and the bag-removing opening 311 allows the bag-removing clamp to smoothly remove the packaging bag 3 from the box.

[0059] According to some embodiments of the present invention, the bag-removing clamp includes a first suction cup 221 and a second suction cup 222. The first suction cup 221 is movably connected to the worktable 10. A first suction port 15 is provided on the top of the first suction cup 221. The second suction cup 222 is connected to the worktable 10. A second suction port 15 is provided on the bottom of the second suction cup 222. The first suction cup 221 moves to the bottom of the second suction cup 222 after the first suction port 15 engages with the bottom of the packaging bag 3, so that the second suction port 15 engages with the top of the packaging bag 3, thereby opening the packaging bag 3.

[0060] In some embodiments, the bag box 30 and the bag retrieval clamp are both located on one side of the workbench 10 in the width direction, and the clamping arm 23 is located on the other side of the workbench 10 in the width direction. The bag box 30 contains a plurality of packaging bags 3, and the opening of each packaging bag 3 is set facing the clamping arm 23.

[0061] During operation, the first suction cup 221 moves along the length direction to below the bag box 30. Then, the first suction cup 221 moves along the height direction and comes into contact with the packaging bag 3. Under the suction force of the first suction cup 221, the first suction cup 221 can stably adhere to the packaging bag 3. Then, the first suction cup 221 moves along the height direction away from the bag box 30 to remove the packaging bag 3. Immediately afterwards, the first suction cup 221 moves along the length direction to below the second suction cup 222. Then, the first suction cup 221 moves along the height direction toward the second suction cup 222 so that the second suction cup 222 contacts the top of the packaging bag 3. Then, the first suction cup 221 moves along the height direction away from the second suction cup 222. At this time, the packaging bag 3 can be opened under the action of the first suction cup 221 and the second suction cup 222.

[0062] The clamping arm 23 moves along the length direction to move the sampled test strip 2 to face the opening of the packaging bag 3. Then, the clamping arm 23 moves toward the packaging bag 3 in the width direction and places the test strip 2 inside the packaging bag 3. Finally, the clamping arm 23 releases the clamp on the test strip 2 and moves away from the packaging bag 3 in the width direction and returns to its original position, thus completing the bagging of the test strip 2.

[0063] Therefore, by using the first suction cup 221 and the second suction cup 222 to adsorb the bottom and top of the packaging bag 3 respectively, the bag 3 can be accurately and stably controlled for taking off and opening, avoiding the problem of damage to the packaging bag 3 or failure to open normally due to inaccurate gripping position, and improving the success rate of taking off and opening the bag.

[0064] According to some embodiments of the present invention, the bag-removing clamp also includes two fixing claws 223, which are respectively connected to the worktable 10, and are located on both sides of the second suction cup 222 in the length direction. The two fixing claws 223 are respectively adapted to clamp the two sides of the opening of the packaging bag 3 when the second suction port 15 is engaged with the top of the packaging bag 3.

[0065] In some embodiments, the bag-removing clamp includes a first suction cup 221 and a second suction cup 222, as well as two fixing claws 223. The two fixing claws 223 are respectively connected to the worktable 10 and are fixed in position. At the same time, the two fixing claws 223 are respectively located on both sides of the second suction cup 222 in the length direction. When the second suction port 15 engages with the top of the packaging bag 3, that is, when the second suction cup 222 adsorbs the top of the packaging bag 3, the two fixing claws 223 start to move and clamp the two sides of the opening of the packaging bag 3 respectively.

[0066] Understandably, when the second suction port 15 engages with the top of the packaging bag 3, the two retaining claws 223 clamp the two sides of the opening of the packaging bag 3 respectively, and then the first suction cup 221 moves away from the second suction cup 222 in the height direction to open the packaging bag 3.

[0067] It is worth noting that by clamping the two sides of the opening of the packaging bag 3 with two fixing claws 223 respectively, the opening of the packaging bag 3 can be prevented from being too large when it is opened, thereby preventing the packaging bag 3 from being torn or damaged during the opening process.

[0068] According to some embodiments of the present invention, the bag box 30 includes a bottom plate 31 and a surrounding plate 32. The surrounding plate 32 is connected to the outer periphery of the bottom plate 31. The surrounding plate 32 and the bottom plate 31 together define a receiving cavity for receiving the packaging bag 3. The bottom plate 31 is provided with a bag opening 311 that extends through its own thickness direction. The surrounding plate 32 and / or the bottom plate 31 are made of transparent material.

[0069] In some embodiments, the surrounding plate 32 is connected to the outer periphery of the bottom plate 31. The surrounding plate 32 and the bottom plate 31 together form a closed or semi-closed space, namely a receiving cavity for accommodating the packaging bag 3. The receiving cavity provides a place for storing the packaging bag 3, so that the packaging bag 3 can be neatly stacked in the bag box 30. The bottom plate 31 is provided with a bag-removing opening 311 that extends through in the thickness direction. The function of the bag-removing opening 311 is to allow the bag-removing clamp to pass through, so that the packaging bag 3 can be removed from the inside of the bag box 30.

[0070] Understandably, the sidewalls of the enclosure 32 are used to laterally restrain the packaging bag 3, preventing it from scattering or tipping over inside the bag box 30. The bottom plate 31 provides support, bearing the weight of the packaging bag 3. When it is necessary to remove the bag, the bag-removing clamp moves to the bag-removing opening 311 of the bag box 30. Since the bag-removing opening 311 extends through the thickness of the bottom plate 31, the bag-removing clamp can reach into the bag box 30 through the bag-removing opening 311, contact the bottom packaging bag 3, and remove the packaging bag 3 from the bag box 30 by means of suction, gripping, etc.

[0071] It is worth mentioning that electrostatic adsorption may occur between the packaging bag to be removed and other packaging bags, resulting in the removal of multiple packaging bags 3 at one time. With the above-described configuration, when the first suction cup 221 engages with and removes the packaging bag 3, the packaging bag 3 to be removed is taken out through the bag-removing opening 311. The portion of the bottom plate 31 located at the outer periphery of the bag-removing opening 311 can obstruct the removal of the packaging bag 3, causing the outer periphery of the packaging bag 3 to be removed to bend and deform, thereby increasing the gap between the packaging bag 3 to be removed and other packaging bags 3. This eliminates the electrostatic adsorption phenomenon between the packaging bags 3, achieving the effect of removing only one packaging bag 3 at a time.

[0072] Of course, in some embodiments, the enclosure 32 is made of transparent material, which allows workers to easily see the quantity and filling status of the packaging bags 3 inside the bagging box 30. In other embodiments, the base plate 31 is made of transparent material, which also allows workers to easily see the quantity and filling status of the packaging bags 3 inside the bagging box 30. In still other embodiments, both the enclosure 32 and the base plate 31 are made of transparent material, which also allows workers to easily see the quantity and filling status of the packaging bags 3 inside the bagging box 30.

[0073] According to some embodiments of the present invention, the collecting component 1 further includes a clamping plate 51, a sealing machine 52, and a laser marking machine 53. The clamping plate 51 is movably connected to the worktable 10. The first station 11, the second station 12, the third station 13, the sealing machine 52, and the laser marking machine 53 are arranged sequentially in the length direction. The clamping plate 51 is adapted to clamp the packaging bag 3 in the thickness direction after the test paper 2 is placed into the packaging bag 3, and the clamping plate 51 moves so that the packaging bag 3 passes through the sealing machine 52 and the laser marking machine 53 in sequence.

[0074] In some embodiments, the clamping plate 51 consists of two opposing clamping components. These two clamping components can be opened and closed by a drive device such as a cylinder or a motor. When it is necessary to clamp the packaging bag 3, the drive device brings the two clamping components closer together, applying a certain pressure to the packaging bag 3, thereby achieving clamping. The clamping plate 51 is movably connected to the worktable 10 through mechanical structures such as guide rails, sliders, and motor drives, so that the clamping plate 51 has flexible movement capabilities, which are not limited here.

[0075] The clamp 51 is located on one side of the workbench 10 in the width direction. After the test paper 2 is placed into the packaging bag 3, the clamp 51 begins to function to clamp the packaging bag 3 in the thickness direction. Then the clamp 51 moves in the length direction so that the packaging bag 3 passes through the sealing machine 52 and the laser marking machine 53 in sequence.

[0076] The sealing machine 52 is set between the bag-removing clamp and the collection box. The main function of the sealing machine 52 is to seal the packaging bag 3 before the clamp 51 transports the packaging bag 3 to the collection box. The purpose of sealing is to seal the opening of the packaging bag 3 to prevent the trace explosive sampling test strip 2 inside from being contaminated by the external environment, getting damp or being accidentally touched. It also facilitates the storage and transportation of the packaging bag 3.

[0077] It should be noted that the sealing machine 52 includes a lower pressure plate and an upper pressure plate. The lower pressure plate is connected to the worktable 10, and the upper pressure plate is movably connected to the worktable 10. The upper pressure plate is adapted to move toward or away from the lower pressure plate in the height direction. When the upper pressure plate and the lower pressure plate cooperate to press the packaging bag 3, the upper pressure plate and / or the lower pressure plate are heated to seal the packaging bag 3.

[0078] After the packaging bag 3 exits the sealing machine 52, it is transported to the coding station of the laser coding machine 53. At this point, the laser coding machine 53 starts, and the laser head codes the top of the packaging bag 3 according to a preset program. It is worth noting that the laser coding machine 53 uses a high-energy-density laser emitted from the laser head to locally irradiate the surface of the packaging bag 3, causing physical or chemical changes in the material on the surface of the packaging bag 3, thereby forming the desired mark.
