Technical Field

[0001] This invention relates to the field of drug detection technology, and in particular to a cap-opening device and an automated hair grinding system for hair processing. Background Technology

[0002] Human hair examination is one of the forensic evidence examination items, involving various scientific tests on human hair. Hair is easily shed and left at crime scenes, and its physical and chemical properties are stable, making it easy to preserve and utilize. Hair can bind to drugs and narcotics in the body, thus reflecting the intake of drugs and narcotics during a corresponding growth period. In drug-related cases, it is of great significance for identifying drug use, recognizing external contamination, and evaluating the effectiveness of drug rehabilitation. The general process for using hair to detect drugs includes: collecting hair samples in sample tubes, washing them with solvents such as methanol, drying them, cutting and grinding them, and finally extracting the analytes from the hair and placing them in test tubes for analysis.

[0003] To reduce the risk of contamination from human operation and improve detection efficiency, it is imperative to develop hair-based drug detection towards a high degree of automation and intelligence. To automate hair grinding, the opening and closing of sample and detection tubes is crucial. However, due to the different sizes of sample and detection tubes, and the need for repeated opening and closing during automated hair processing, designing an opening and closing device suitable for an automated hair-based drug detection system is a pressing issue that needs to be addressed.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, unless otherwise stated, "a plurality of" means two or more.

[0023] To address the problems existing in the prior art, embodiments of the present invention provide a cap-opening device for hair removal, as shown in the reference. Figure 1 As shown, the system includes a long, narrow substrate 1, which is divided along its length into a pipetting area and a capping area. A moving mechanism 2 is disposed on the substrate 1 and includes a movably disposed clamping seat 21, which can move back and forth between the pipetting area and the capping area. The clamping seat 21 is provided with a clamping assembly 22, which is used to clamp and fix the sample tube 304 and the detection tube 305. A capping mechanism 3 is disposed on the substrate 1 and close to the capping area. The capping mechanism 3 includes a finger clamping assembly 31, which is used to open the cap of the sample tube 304 or the detection tube 305.

[0024] In operation, the moving mechanism 2 controls the clamping seat 21 to move to the pipetting area, places the sample tube 304 and the detection tube 305 on the clamping seat 21 and fixes them by the clamping assembly 22, controls the clamping seat 21 to move to the opening area, opens the caps of the sample tube 304 and the detection tube 305 by the finger clamping assembly 31, and then moves the clamping seat 21 to the pipetting area for pipetting.

[0025] In this embodiment, the cap of the sample tube 304 or the detection tube 305 is opened by the cap opening mechanism 3, thereby ensuring the reliability of opening and closing the caps of the sample tube 304 and the detection tube 305 and improving the efficiency of automated hair grinding process.

[0026] refer to Figure 1 and Figure 3As shown, in some embodiments, the moving mechanism 2 further includes a carrier 23 disposed on the clamping base 21. The carrier 23 is fixedly disposed in the middle of the clamping assembly 22, and has a carrier groove 231, a first carrier hole 232, and a second carrier hole 233 sequentially formed along the moving direction of the clamping base 21. The carrier groove 231 is used to place the cap of the detection tube 305, the first carrier hole 232 is used to place the detection tube 305, and the second detection hole is used to place the sample tube 304.

[0027] In this embodiment, both the first bearing hole 232 and the second bearing hole 233 are blind holes, and the diameter of the first bearing hole 232 is adapted to the diameter of the detection tube 305, and the diameter of the second bearing hole 233 is adapted to the diameter of the sample tube 304, so that the detection tube 305 can be inserted into the first bearing hole 232 and the sample tube 304 can be inserted into the second bearing hole 233, and the clamping assembly 22 can simultaneously fix the detection tube 305 and the sample tube 304.

[0028] It is understandable that, since the support groove 231 can hold the cap of the detection tube 305, the finger clamping assembly 31 can unscrew the cap of the detection tube 305 and place it on the support groove 231. Then, the finger clamping assembly 31 can also open the cap of the sample tube 304, thereby improving the processing efficiency.

[0029] In some embodiments, the carrier 23 has grooves 234 on both sides, and the grooves 234 communicate with the first carrier hole 232 and the second carrier hole 233. The clamping assembly 22 includes a left clamping finger 221 and a right clamping finger 222 located on both sides of the carrier 23. The left clamping finger 221 and the right clamping finger 222 correspond to the grooves 234 respectively, and can be moved to the groove 234 area to clamp and fix the sample tube 304 and the detection tube 305.

[0030] Furthermore, the moving mechanism 2 includes a first driver 24 disposed on the clamping base 21. The first driver 24 is provided with a first clamping part 241 and a second clamping part 242 that can move closer to or further away from each other. The left clamping finger 221 is connected to the first clamping part 241, and the right clamping finger 222 is connected to the second clamping part 242.

[0031] When the first driver 24 drives the first clamping part 241 and the second clamping part 242 to move closer or further apart, it drives the left clamping finger 221 and the right clamping finger 222 to move closer or further apart, thereby achieving clamping and fixing or loosening of the sample tube 304 and the detection tube 305.

[0032] In this embodiment, the first actuator 24 can be a pneumatic gripper. The left gripping finger 221 and the right gripping finger 222 are symmetrically distributed, and the width of the left gripping finger 221 and the right gripping finger 222 is smaller than the width of the groove 234, so that the first actuator 24 can drive the left gripping finger 221 and the right gripping finger 222 into the groove 234 to clamp and fix the sample tube 304 and the detection tube 305.

[0033] refer to Figures 2 to 4 As shown, in some embodiments, the left gripper finger 221 is provided with a first left gripping groove 2211 and a second left gripping groove 2212, and the right gripper finger 222 is provided with a first right gripping groove 2221 and a second right gripping groove 2222. The first left gripping groove 2211, the second left gripping groove 2212, the first right gripping groove 2221, and the second right gripping groove 2222 are all arc-shaped structures.

[0034] When the first driver 24 is driven to bring the left clamping finger 221 and the right clamping finger 222 closer to each other, the first left clamping groove 2211 and the first right clamping groove 2221 cooperate to form a clamping ring adapted to the detection tube 305, and the second left clamping groove 2212 and the second right clamping groove 2222 cooperate to form a clamping ring adapted to the sample tube 304.

[0035] In this embodiment, both the left clamping finger 221 and the right clamping finger 222 are detachably connected to the first driver 24, and the diameter of the clamping ring formed by the first left clamping groove 2211 and the first right clamping groove 2221 is the same as the outer diameter of the detection tube 305, and the diameter of the clamping ring formed by the second left clamping groove 2212 and the second right clamping groove 2222 is the same as the outer diameter of the sample tube 304.

[0036] refer to Figure 3 As shown, in some embodiments, the top of the bearing groove 231, the first bearing hole 232 and the second bearing hole 233 are all provided with guide walls 235 with different radial dimensions. Each guide wall 235 is inclined and the diameter of the guide wall 235 gradually increases in the direction away from the clamping seat 21.

[0037] In this embodiment, when the sample tube 304 or the detection tube 305 is grasped and brought close to the first bearing hole 232 or the second bearing hole 233, the guide wall 235 provided on the top of each tube ensures that the tube can smoothly enter the first bearing hole 232 or the second bearing hole 233 along the correct trajectory, which greatly improves the accuracy of placement and the efficiency of the overall operation.

[0038] refer to Figure 1 As shown, in some embodiments, the moving mechanism 2 further includes a slide rail 25 and a second driver 26. The slide rail 25 is disposed on the substrate 1, and both ends of the slide rail 25 extend to the pipetting area and the capping area, respectively. A sliding plate 27 is provided on the slide rail 25. The second driver 26 is used to drive the sliding plate 27 to move. The clamping seat 21 is disposed on the sliding plate 27.

[0039] In this embodiment, the second actuator 26 provides power to the slide plate 27, thereby enabling the slide plate 27 to move back and forth between the pipetting area and the opening area.

[0040] In some embodiments, the cap-opening mechanism 3 further includes a connecting plate 32, a third actuator 33, a drive motor 34, and a sliding assembly 35. The connecting plate 32 is vertically disposed on the base plate 1, and the sliding assembly 35 is disposed on the connecting plate 32. The sliding assembly 35 has a slider 351 that can slide up and down in a vertical direction. The drive motor 34 is disposed on the connecting plate 32 and connected to the sliding assembly 35, and is used to drive the slider 351 to slide up and down in a vertical direction. The third actuator 33 is disposed on the slider 351, and the finger-clamping assembly 31 is provided on the driving end of the third actuator 33. The third actuator 33 is used to drive the finger-clamping assembly 31 to rotate and clamp or release the caps of the sample tube 304 and the detection tube 305.

[0041] In this embodiment, the third actuator 33 can be a rotary clamping motor. It is understood that the rotary clamping motor can both rotate the drive end and drive the finger clamping assembly 31 to clamp the sample tube 304. When it is necessary to open the sample tube 304, the drive motor 34 drives the slider 351 to move downwards, so that the finger clamping assembly 31 approaches the cap of the sample tube 304. Then, the third actuator 33 drives the finger clamping assembly 31 to clamp the cap of the sample tube 304 and rotate it to separate the cap of the sample tube 304 from the tube body. Similarly, the cap of the detection tube 305 is opened in the same way, which will not be described in detail here.

[0042] In yet another embodiment of the present invention, an automated hair refining system is provided, with reference to... Figures 5 to 7 As shown, the device includes a chamber 100, a grinder 200, a stack 300, a main transport robot 400, and a sample extraction device 500. The chamber 100 is internally divided into a grinding area 101, a transport area 102, and a sample extraction area 103. The grinder 200 is located in the grinding area 101, close to one side of the chamber 100, and is used to grind the hair sample inside the sample tube 304.

[0043] The stack 300 is located in the transport area 102 and close to the grinder 200. The stack 300 holds a pipette tip 301, a reagent kit 302, a filter collection plate 303, a sample tube 304, and a detection tube 305. The main transport robot 400 is located in the transport area 102 and is used to transfer the pipette tip 301, the reagent kit 302, the filter collection plate 303, the sample tube 304, and the detection tube 305 within the chamber 100.

[0044] The sample extraction device 500 is located in the sample extraction area 103. The sample extraction device 500 includes the cap opening device 501 provided in the above embodiment. The sample extraction device 500 is used to extract the liquid in the sample tube 304 into the detection tube 305.

[0045] In this embodiment, by arranging the grinder 200, the stack 300, the main transport robot 400, and the sample extraction device 500 within the chamber 100, and through a reasonable spatial layout and a designed automated control program, the hair grinding process is automated, reducing the risk of contamination from human operation and improving the efficiency of drug detection using hair.

[0046] In some embodiments, the sample extraction device 500 further includes a cap opening device 501, a robotic arm 502, a positive pressure device 503, and a centrifuge 504. A partition 110 is provided within the chamber 100, located in the sample extraction area 103 and dividing the sample extraction area 103 into an upper area and a lower area. The upper area is further divided into a first storage area, a second storage area, a third storage area, a fourth storage area, and a fifth storage area. The pipette tip 301 is placed in the first storage area; the reagent kit 302 is transported to the second storage area; the filter collection plate 303 is placed in the third storage area; the sample tube 304 is placed in the fourth storage area; and the detection tube 305 is placed in the fifth storage area.

[0047] The centrifuge 504 is located in the lower region and is used to centrifuge the hair sample in the sample tube 304 after grinding to obtain sample supernatant. The positive pressure device 503 is located in the lower region and uses positive pressure to obtain the detection liquid from the sample supernatant and collect the detection liquid in the internal filter collection plate 303. The cap opening device 501 and the robot arm 502 are located in the upper region. The robot arm 502 includes a transport gripper and an installation head. The transport gripper is used to transport the sample tube 304 and the detection tube 305 to the clamping seat 21. The installation head is used to install the aspiration pipette head 301 and transfer the liquid in the sample tube 304 to the positive pressure device 503 through the aspiration pipette head 301, and extract the detection liquid from the filter collection plate 303 of the positive pressure device 503 and transfer it to the detection tube 305.

[0048] It should be noted that the reagent kit 302 contains methanol, and the filter collection plate 303 includes an upper filter plate and a lower collection plate. The filter collection plate 303 is used in the positive pressure device 503 to filter and collect the test solution. For ease of handling and collection, and to process multiple hair samples simultaneously, multiple aspirator tips 301, multiple sample tubes 304, and multiple test tubes 305 can be placed on corresponding tray structures, and then placed on the stack 300.

[0049] To facilitate understanding of the specific operation process of the automated hair refining system provided in this application, the following references are provided. Figures 1 to 7 It is described in detail: After preparing the pipette tip 301, reagent kit 302, filter collection plate 303, sample tube 304, and detection tube 305 in advance, place them in the stack 300, as follows: Figure 7 As shown. Then, start the automated hair resurfacing system.

[0050] The main transport robot 400 sequentially transports the pipette tip 301, reagent kit 302, filter collection plate 303, sample tube 304, and detection tube 305 from the stack 300 to the first storage area, second storage area, third storage area, fourth storage area, and fifth storage area, as follows: Figure 6 As shown.

[0051] The robotic arm 502 in the sample extraction device 500 controls the gripper to fix the sample tube 304 and places the sample tube 304 on the gripper 21. The gripper assembly 22 on the gripper 21 clamps and fixes the sample tube 304.

[0057] The main transport robot 400 transports the sample tube 304 to the grinder 200 for grinding.

[0058] After grinding is completed, the main transport robot 400 transports the sample tube 304 to the centrifuge 50454 for centrifugation, so that the hair powder settles at the bottom of the sample tube 304.

[0059] After centrifugation is complete, the main transport robot 400 transports the sample tube 304 to the fourth storage area.

[0062] The robotic arm 502 controls the pipette tip 301 to aspirate the supernatant formed after centrifugation from the sample tube 304, and then introduces the aspirated supernatant into the filter collection plate 303. It can be understood that the pipette tip 301 at this time is a new pipette tip 301, that is, the pipette tip 301 needs to be replaced every time the liquid is transferred.

[0063] After the supernatant is collected, the capping device 501 controls the gripper assembly 31 to close the cap of the sample tube 304, and the gripper of the robot arm 502 moves the sample tube 304 to the fourth storage area.
