Description

Technical Field

[0001] The utility model relates to the technical field of screw capping devices, in particular to a screw capping device for a centrifuge tube. Background Art

[0002] For patients with mental illness and those in sub-health conditions, some hospitals have built automated biobanks that can store large numbers of samples. During the use of automated biobanks, collected samples need to be centrifuged, packaged, and stored. During the sample packaging process, medical staff need to transfer samples from sample tubes into centrifuge tubes to ensure storage.

[0003] Centrifuge tubes have threaded or snap-on caps, which can be opened or closed by connecting or separating the cap from the tube body. However, due to the clamping requirements of automated biological sample libraries or to avoid interference of snap-on caps with sample packaging, most automated biological sample libraries currently use centrifuge tubes with threaded caps.

[0004] However, during the sample packaging process, medical staff often need to manually open or close the cap of the centrifuge tube, which is troublesome and increases the workload of medical staff. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] The utility model provides a centrifuge tube capping device, comprising: a workbench, a centrifuge tube placement tray and a cap placement tray connected to the workbench, the centrifuge tube placement tray being provided with a plurality of perforations arranged in an array, and the cap placement tray being provided with a plurality of placement slots arranged in an array; a code scanner connected to the workbench and located below the centrifuge tube placement tray; a clamping mechanism arranged on the workbench, the clamping mechanism comprising a first driving device and two chucks; the first driving device being transmission-connected to the chucks to drive the two chucks toward or away from each other; a moving assembly mounted above the workbench; an electric rotating claw connected to the moving assembly, and the moving assembly can drive the electric rotating claw to move between the centrifuge tube placement tray, the cap placement tray and the clamping mechanism.

[0007] A centrifuge tube capping device provided according to an embodiment of the present invention has at least the following beneficial effects: a centrifuge tube placement tray and a cap placement tray are connected to a workbench. When in use, medical staff can place the centrifuge tube in the centrifuge tube placement tray, and the centrifuge tube is inserted into the perforation to realize the positioning of the centrifuge tube. A QR code is affixed to the lower end of the centrifuge tube, and the placement information of the centrifuge tube in the centrifuge tube placement tray can be automatically obtained in conjunction with the setting of the code scanner; when the centrifuge tube needs to be capped, the moving component is connected to the electric rotating claw to drive the electric rotating claw to move to the centrifuge tube placement tray, and the electric rotating claw can be used to clamp the centrifuge tube, and then the centrifuge tube can be moved to the clamping mechanism The two chucks of the clamping mechanism are brought close to each other, so that the clamping mechanism can clamp the lower end of the centrifuge tube, and then the electric rotating claw can drive the cap to rotate relative to the tube body, that is, the cap is separated from the tube body, and the separated cap can be placed in the placement groove of the cap placement tray, and then the centrifuge tube after capping can be put back to the original position of the centrifuge tube placement tray to complete the capping operation of one centrifuge tube. Correspondingly, the moving component can drive the electric rotating claw to screw the cap in the placement groove into the tube body of the centrifuge tube, that is, the centrifuge tube capping device can automatically open or close the centrifuge tube, which is beneficial to reduce the labor intensity of medical staff and avoid the problem of sample contamination caused by manual operation.

[0008] According to some embodiments of the present invention, the centrifuge tube placement tray is detachably connected to the workbench.

[0009] The centrifuge tube placement tray is detachably connected to the workbench. When in use, the medical staff can connect the centrifuge tube placement tray with the centrifuge tubes placed thereon to the workbench. With the cooperation of the moving assembly, the electric rotating clamp and the clamping mechanism, the caps of the centrifuge tubes can be opened or screwed on. After the caps of the centrifuge tubes are opened, the medical staff can take the entire centrifuge tube placement tray out of the workbench, and automatically realize the sample packaging operation of the centrifuge tubes under the external sample packaging device, which meets the current use requirements of automated biological sample libraries. After the sample packaging is completed, the centrifuge tube placement tray can be connected to the workbench again, so that the caps can be screwed on. That is, the detachable connection between the centrifuge tube placement tray and the workbench is conducive to avoiding the trouble of repeatedly inserting the centrifuge tubes into the perforations, which is conducive to improving the work efficiency of medical staff.

[0010] According to some embodiments of the present invention, a plurality of positioning posts are provided on the workbench, and the centrifuge tube placement tray can be plugged into or separated from the positioning posts.

[0011] Specifically, a plurality of positioning pillars are provided on the workbench. When the centrifuge tube placing tray needs to be connected to the workbench, the medical staff can plug the centrifuge tube placing tray into the positioning pillars. Through the mutual limitation of the centrifuge tube placing tray and the positioning pillars, the centrifuge tube placing tray and the workbench can be positioned and fixed, which is conducive to the barcode scanner to scan and identify the centrifuge tubes in the centrifuge tube placing tray, and is conducive to the fixed-point movement of the mobile component; the medical staff separates the centrifuge tube placing tray from the positioning pillars and removes the centrifuge tube placing tray from the workbench. The operation is relatively simple and convenient.

[0012] According to some embodiments of the present invention, the through hole is a tapered hole that is larger at the top and smaller at the bottom.

[0013] Specifically, considering that the upper end of the centrifuge tube is larger than the lower end, the perforation on the centrifuge tube placement plate is adapted to be a tapered hole that is larger at the top and smaller at the bottom. When the centrifuge tube is inserted into the perforation, the outer surface of the centrifuge tube and the inner surface of the perforation can fit each other, thereby improving the stability of the centrifuge tube placed on the centrifuge tube placement plate, which is conducive to the electric rotating claw being able to stably clamp the centrifuge tube after the moving component moves the electric rotating claw into place.

[0014] According to some embodiments of the present invention, the workbench is provided with a concave embedding groove, the code scanner is embedded in the embedding groove, the scanning direction of the code scanner is set upward, and the upper edge of the embedding groove is covered with a transparent plate.

[0015] In order to increase the distance between the barcode scanner and the centrifuge tube placement tray so that the barcode scanner can identify the centrifuge tubes in the entire centrifuge tube placement tray, the workbench is provided with a concave groove, the barcode scanner is arranged in the groove, and the scanning direction of the barcode scanner is set upward. When the centrifuge tube placement tray is connected to the positioning column, the barcode scanner is set opposite the lower end of the centrifuge tube placement tray. Since the perforations of the centrifuge tube placement tray are set to pass through from top to bottom, the barcode scanner can identify the centrifuge tubes placed in the perforations, that is, identify the centrifuge tube placement information in the centrifuge tube placement tray. The upper edge of the groove is covered with a transparent plate. The setting of the transparent plate can prevent external dust, liquid, etc. from entering the groove and contaminating the barcode scanner. The barcode scanner can also identify the centrifuge tubes in the centrifuge tube placement tray through the transparent plate.

[0016] According to some embodiments of the present invention, a limiting block is provided on the periphery of the positioning column, and the lower end of the centrifuge tube placement plate can abut against the limiting block, and the height of the limiting block is higher than the height of the code scanner.

[0017] Optionally, in order to increase the distance between the barcode scanner and the centrifuge tube placement tray so that the barcode scanner can identify the centrifuge tubes in the entire centrifuge tube placement tray, a limit block is provided at the outer periphery of the positioning column. When the centrifuge tube placement tray is plugged into the positioning column, the lower end of the centrifuge tube placement tray can be abutted against the limit block, thereby increasing the height between the centrifuge tube placement tray and the upper surface of the workbench, and the height of the limit block is higher than the height of the barcode scanner, so that the barcode scanner can identify the centrifuge tubes in the centrifuge tube placement tray, which is conducive to avoiding the problem that the centrifuge tube placement tray cannot be placed flat due to the setting of the barcode scanner.

[0018] According to some embodiments of the present invention, the present invention further includes a cover body and an air purifier. The cover body is movably connected to the workbench. The cover body and the workbench can together form a working chamber. The air purifier is connected to the working chamber.

[0019] Furthermore, in order to maintain a sterile environment for the centrifuge tube during the cap opening or closing operation, the screw-capping device of the centrifuge tube also includes a cover body and an air purifier. When the cover body is connected to the workbench, the cover body and the workbench can together form a relatively sealed working chamber, and the air purifier is connected to the working chamber. The air purifier can purify the air in the working chamber, thereby maintaining a sterile environment in the working chamber, which is beneficial to reducing the risk of contamination of the centrifuge tube during the cap opening or closing operation.

[0020] According to some embodiments of the present invention, the electric rotating clamp includes a second drive device, a third drive device and two clamping jaws. The second drive device is connected to the clamping jaws for driving the two clamping jaws towards or away from each other; the third drive device is connected to the clamping jaws for driving the clamping jaws to rotate.

[0021] Specifically, the electric rotating clamp includes a second drive device, a third drive device and two claws. When the centrifuge tube needs to be clamped, the moving assembly can move the electric rotating clamp to the top of the centrifuge tube, and the second drive device drives the two claws away from each other, and cooperates with the downward movement of the moving assembly to place the centrifuge tube between the two claws. The second drive device can drive the two claws closer to each other, thereby clamping the centrifuge tube. When the clamping mechanism clamps the tube body of the centrifuge tube and the electric rotating clamp clamps the cap of the centrifuge tube, it cooperates with the rotation of the third drive device to realize the relative rotation of the cap and the tube body, that is, the opening or closing of the cap is realized. The degree of automation is high, which is conducive to avoiding the problem that medical staff need to frequently open or close the cap.

[0022] According to some embodiments of the present invention, the present invention further includes a pressure sensor, which is connected to the clamping jaws and is located between the two clamping jaws.

[0023] Specifically, the pressure sensor is connected to the claws and is located between the two claws. When the claws approach each other relative to the centrifuge tube, the pressure sensor can abut against the centrifuge tube to assist the second drive device in stably clamping the centrifuge tube and avoid the problem of damage to the centrifuge tube caused by excessive clamping force of the two claws.

[0024] According to some embodiments of the present invention, the moving assembly is a three-axis manipulator, and the moving assembly can drive the electric rotary clamp to move in a vertical plane and a horizontal plane.

[0025] Specifically, the moving component is a three-axis manipulator, that is, the moving component can drive the electric rotating claw to move in the vertical plane and the horizontal plane, and cooperate with the clamping and rotation of the electric rotating claw to realize the separation and screwing of the cap and the tube body. That is, the centrifuge tube capping device can replace manual labor to realize the separation and screwing of the centrifuge tube cap, which is conducive to improving the work efficiency of medical staff.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] Reference below Figures 1 to 7 To describe, a centrifuge tube capping device provided in an embodiment of the utility model can automatically realize the separation and screwing of the centrifuge tube cap and the tube body through structural design, which is beneficial to reduce the labor intensity of medical staff and reduce the risk of contamination caused by manual operation.

[0042] Understandably, see Figure 1 and Figure 2 According to an embodiment of the present invention, a centrifuge tube capping device includes: a workbench 100, a barcode scanner 300, a clamping mechanism 400, a moving component 500 and an electric rotating clamp 600.

[0043] The workbench 100 is connected to a centrifuge tube tray 210 and a cap tray 220. The centrifuge tube tray 210 is provided with a plurality of arrayed perforations 211, which allow centrifuge tubes to be inserted into the perforations 211. When a centrifuge tube is inserted into the perforations 211, the centrifuge tube is positioned. The cap tray 220 is provided with a plurality of arrayed slots 221, which temporarily store centrifuge tube caps.

[0044] Understandably, see Figure 3 The code scanner 300 is connected to the workbench 100 and is located below the centrifuge tube placement tray 210. A QR code may be affixed to the lower end of the centrifuge tube. The code scanner 300 is arranged in a scanning direction facing the lower end of the centrifuge tube placement tray 210, and the perforations 211 are arranged to pass through from top to bottom. That is, when a centrifuge tube is inserted into the perforations 211, the code scanner 300 can automatically identify the placement information of the centrifuge tube in the centrifuge tube placement tray 210, such as the number of centrifuge tubes placed in the centrifuge tube placement tray 210 and the approximate distribution of the multiple centrifuge tubes. The centrifuge tube capping device can assist in the input of information through the setting of the code scanner 300.

[0045] Understandably, see Figure 1 and Figure 5 The clamping mechanism 400 is disposed on the workbench 100 and includes a first drive device and two chucks 410. The first drive device is in transmission connection with the chucks 410 to drive the two chucks 410 toward or away from each other. Specifically, the first drive device can be configured as a linear drive mechanism such as an air cylinder, an oil cylinder, an electric push rod, a screw slider drive mechanism, etc., so as to meet the use requirements of driving the two chucks 410 toward or away from each other.

[0046] The moving assembly 500 is mounted above the workbench 100 and is connected to the electric rotating clamp 600 . The moving assembly 500 can drive the electric rotating clamp 600 to move between the centrifuge tube placement tray 210 , the cap placement tray 220 and the clamping mechanism 400 .

[0047] See also Figure 1 and Figure 5 When the centrifuge tube needs to be capped, the medical staff can insert the centrifuge tube into the through-hole 211 in the centrifuge tube placement tray 210 , and then start the barcode scanner 300 , through which the centrifuge tube in the centrifuge tube placement tray 210 can be identified and entered.

[0048] See also Figure 2 and Figure 4 The moving assembly 500 is transmission-connected with the electric rotating clamp 600 to drive the electric rotating clamp 600 to move to the centrifuge tube placement tray 210, and the electric rotating clamp 600 can clamp the centrifuge tube, and then the centrifuge tube can be moved to the clamping mechanism 400. By the two chucks 410 of the clamping mechanism 400 approaching each other, the clamping mechanism 400 can clamp the lower end of the centrifuge tube, and the electric rotating clamp 600 can clamp the cap of the centrifuge tube, thereby driving the cap to rotate relative to the tube body, that is, realizing the separation of the cap from the tube body, and the separated cap can be placed in the placement groove 221 of the cap placement tray 220, and then the centrifuge tube after capping can be put back to the original position of the centrifuge tube placement tray 210 to complete the capping operation of one centrifuge tube, and so on, the caps of the centrifuge tubes in the entire centrifuge tube placement tray 210 can be opened, and the centrifuge tubes after capping can be used to realize sample packaging.

[0049] When the sample packaging is completed and the centrifuge tube needs to be capped, the moving component 500 can drive the electric rotating clamp 600 to move to the centrifuge tube placement tray 210 to clamp a centrifuge tube, and move the centrifuge tube to the clamping mechanism 400. The clamping mechanism 400 can clamp and fix the tube body of the centrifuge tube, and then the moving component 500 can drive the electric rotating clamp 600 to move to the cap placement tray 220. The electric rotating clamp 600 can clamp the cap of the corresponding tube body. Under the rotation action of the electric rotating clamp 600, the cap and the tube body of the centrifuge tube can be screwed together, that is, the cap of the centrifuge tube can be screwed together.

[0050] That is, the screw capping device of the centrifuge tube can automatically open or close the centrifuge tube, which is beneficial to reducing the labor intensity of medical staff and the risk of sample contamination caused by manual operation.

[0051] It should be noted that the moving assembly 500 can achieve fixed-point clamping and capping of each centrifuge tube through a preset program.

[0052] It should be understood that in some other embodiments, since the centrifuge tube placement tray 210 and the barcode scanner 300 are relatively stationary, to a certain extent, the barcode scanner 300 can assist in identifying the coordinate information of each centrifuge tube by identifying the QR code under the centrifuge tube, thereby assisting in the fixed-point movement of the moving component 500 to achieve clamping of each centrifuge tube.

[0053] Understandably, see Figure 1 and Figure 5 In this embodiment, considering that the upper end of the centrifuge tube is larger than the lower end, the through-hole 211 on the centrifuge tube placement tray 210 is a tapered hole that is larger at the top and smaller at the bottom. When the centrifuge tube is inserted into the through-hole 211, the outer surface of the centrifuge tube and the inner surface of the through-hole 211 can fit each other, thereby improving the stability of the centrifuge tube placed on the centrifuge tube placement tray 210, which is beneficial for the electric rotating jaw 600 to be able to stably clamp the centrifuge tube after the moving component 500 moves the electric rotating jaw 600 into place.

[0054] The inner diameter of the placement groove 221 is larger than the outer diameter of the lower end of the cap, and the inner diameter of the placement groove 221 is smaller than the outer diameter of the upper end of the cap, that is, when the cap is placed in the placement groove 221, the upper end of the cap is protruding from the placement groove 221, so that the electric rotating clamp 600 can be used to clamp or separate the cap.

[0055] Understandably, see Figure 1 and Figure 6 Furthermore, in order to avoid the trouble of medical staff having to repeatedly connect or separate the centrifuge tube and the perforation 211, the centrifuge tube placement plate 210 of the centrifuge tube capping device is detachably connected to the workbench 100.

[0056] During use, medical staff can connect the centrifuge tube placement tray 210 containing the centrifuge tubes to the workbench 100. With the cooperation of the moving component 500, the electric rotating clamp 600 and the clamping mechanism 400, the cap of the centrifuge tube can be opened or screwed on. After the cap of the centrifuge tube is opened, the medical staff can take the entire centrifuge tube placement tray 210 out of the workbench 100. Under the sample filling device of the automated biological sample library, the sample filling operation of the centrifuge tube can be automatically realized, which meets the current use requirements of the automated biological sample library.

[0057] After the subpackaging is completed, the medical staff can connect the centrifuge tube placement tray 210 to the workbench 100 again, so that the cap can be screwed on. That is, the detachable connection between the centrifuge tube placement tray 210 and the workbench 100 is helpful to avoid the trouble of repeatedly inserting the centrifuge tube into the perforation 211, which is helpful to improve the work efficiency of the medical staff.

[0058] Understandably, see Figure 1and Figure 6 Specifically, the workbench 100 is provided with a plurality of positioning posts 120, and the centrifuge tube placement tray 210 is adapted to be provided with a plurality of sockets, which correspond one-to-one to the positioning posts 120. By docking or separating the sockets and the positioning posts 120, the centrifuge tube placement tray 210 and the workbench 100 can be connected or separated.

[0059] When it is necessary to connect the centrifuge tube placing tray 210 to the workbench 100, the medical staff can plug the centrifuge tube placing tray 210 into the positioning column 120. Through the mutual limitation of the centrifuge tube placing tray 210 and the positioning column 120, the centrifuge tube placing tray 210 and the workbench 100 can be positioned and fixed, which is conducive to the fixed-point movement of the moving component 500; the medical staff can separate the centrifuge tube placing tray 210 from the positioning column 120 and remove the centrifuge tube placing tray 210 from the workbench 100. The operation is relatively simple and convenient.

[0060] Understandably, see Figure 3 In order to increase the distance between the code scanner 300 and the centrifuge tube placement tray 210 so that the code scanner 300 can identify the centrifuge tubes in the entire centrifuge tube placement tray 210, the workbench 100 is provided with a concave embedding groove 110, and the code scanner 300 is arranged in the embedding groove 110. The lower end of the code scanner 300 is connected to the bottom surface of the groove 110, and the scanning direction of the code scanner 300 is set upward, that is, the scanning direction of the code scanner 300 is set relative to the lower end of the centrifuge tube placement tray 210.

[0061] When the centrifuge tube placement tray 210 is connected to the positioning column 120, the code scanner 300 is arranged opposite the lower end of the centrifuge tube placement tray 210. Since the through-hole 211 of the centrifuge tube placement tray 210 is arranged to pass through from top to bottom, the code scanner 300 can identify the centrifuge tube placed in the through-hole 211, that is, identify the centrifuge tube placement information in the centrifuge tube placement tray 210.

[0062] Understandably, see Figure 7 To prevent external dust, liquid, etc. from entering the groove 110 and contaminating the barcode scanner 300, the upper edge of the groove 110 is covered with a transparent plate 800. The barcode scanner 300 can also identify the centrifuge tubes in the centrifuge tube tray 210 through the transparent plate 800. The transparent plate 800 also prevents dust and particles above the workbench 100 from entering the groove 110 and contaminating the barcode scanner 300. Specifically, the transparent plate 800 can be a glass plate, a transparent acrylic plate, etc.

[0063] It should be understood that in some other embodiments, in order to increase the distance between the code scanner 300 and the centrifuge tube placement tray 210 so that the code scanner 300 can identify the centrifuge tubes in the entire centrifuge tube placement tray 210, a limit block is provided at the outer periphery of the positioning column 120. When the centrifuge tube placement tray 210 is plugged into the positioning column 120, the lower end of the centrifuge tube placement tray 210 can be abutted against the limit block, thereby increasing the height between the centrifuge tube placement tray 210 and the upper surface of the workbench 100.

[0064] The height of the limit block is higher than the height of the code scanner 300, which is beneficial to increase the distance between the code scanner 300 and the centrifuge tube placement tray 210, thereby facilitating the code scanner 300 to identify the centrifuge tubes in the centrifuge tube placement tray 210, and is beneficial to avoiding the problem that the centrifuge tube placement tray 210 cannot be placed flat due to the setting of the code scanner 300.

[0065] Understandably, see Figure 1 and Figure 2 In this embodiment, in order to maintain a sterile environment of the centrifuge tube during the cap opening or closing operation, the centrifuge tube capping device further includes a cover body 700 and an air purifier.

[0066] When the cover 700 is connected to the workbench 100, the cover 700 and the workbench 100 can together enclose a relatively sealed working chamber. The front end of the cover 700 is movably connected to a door body, which can open or close the working chamber. When the door body is opened, medical personnel can insert or remove the centrifuge tube placement tray 210 into the working chamber to connect or disconnect the centrifuge tube placement tray 210 from the workbench 100. The cover 700 and the workbench 100 can form a relatively sealed working chamber, which helps to reduce the impact of the external environment on the opening or closing of the centrifuge tube and reduce the risk of contamination of the sample in the centrifuge tube.

[0067] Understandably, see Figure 1 and Figure 5 The centrifuge tube capping device also includes an air purifier. A chamber is provided within the workbench 100, and the air purifier can be disposed within the chamber. The workbench 100 has a plurality of aligned air inlets 130 and exhaust ports disposed on its upper surface. Both the air inlets 130 and exhaust ports are connected to the chamber. The air purifier includes a filter and a fan.

[0068] Filters are provided at both the air inlet 130 and the exhaust port. When the door closes the housing 700, the working chamber is sealed. When the fan is activated, air is circulated within the working chamber. During this air circulation, the filters absorb impurities within the air, thereby improving the air purity within the working chamber. An air purifier is connected to the working chamber and purifies the air within the working chamber, thereby maintaining a sterile environment within the working chamber and reducing the risk of contamination of the centrifuge tube during the cap opening or closing process.

[0069] It is understandable that the capping device of the centrifuge tube also includes an ultraviolet sterilization lamp, which is connected to the top surface of the cover body 700. The ultraviolet sterilization lamp can be used to sterilize the working chamber, which is conducive to creating a sterile environment for opening or screwing the centrifuge tube.

[0070] Understandably, see Figure 2 and Figure 4 The electric rotating clamp 600 includes a second driving device 620, a third driving device 610 and two clamping jaws 630. The second driving device 620 is transmission-connected to the clamping jaws 630 to drive the two clamping jaws 630 to move closer to or away from each other; the third driving device 610 is transmission-connected to the clamping jaws 630 to drive the clamping jaws 630 to rotate.

[0071] When it is necessary to clamp the centrifuge tube, the moving component 500 can move the electric rotating clamp 600 to the top of the centrifuge tube, and the second driving device 620 drives the two clamping claws 630 away from each other, and cooperates with the downward movement of the moving component 500 to place the centrifuge tube between the two clamping claws 630. The second driving device 620 can drive the two clamping claws 630 closer to each other, thereby achieving clamping of the centrifuge tube. The moving component 500 can move the centrifuge tube to the clamping mechanism 400. After the clamping mechanism 400 clamps the tube body of the centrifuge tube and the electric rotating clamp 600 clamps the cap of the centrifuge tube, it cooperates with the rotation of the third driving device 610 to achieve relative rotation between the cap and the tube body, that is, the opening or closing of the cap is achieved. The degree of automation is high, which is conducive to avoiding the problem that medical staff need to frequently open or close the cap.

[0072] Specifically, the second drive device 620 can be a screw-slider mechanism, an electric push rod, or the like. Alternatively, the two clamping claws 630 and the second drive device 620 can together form a pneumatic clamping finger. The third drive device 610 can be a forward and reverse motor that can drive the clamping claws 630 to rotate forward or reverse to open or close the cap and the tube body.

[0073] It is understandable that the capping device of the centrifuge tube further includes a pressure sensor, which is connected to the claws 630 and is located between the two claws 630.

[0074] When the jaws 630 approach the centrifuge tube, the pressure sensor contacts the tube, assisting the second drive mechanism 620 in maintaining a stable grip on the tube and preventing damage to the tube caused by excessive clamping force from the two jaws 630. The electric rotary jaws 600 also feature force feedback, detecting the cap's opening and closing, slippage, and other conditions during operation, effectively securing and disconnecting the cap from the tube.

[0075] Understandably, see Figure 5 The moving component 500 is a three-axis manipulator, that is, the moving component 500 can drive the electric rotating clamp 600 to move in the vertical plane and the horizontal plane, and cooperate with the clamping and rotation of the electric rotating clamp 600 to realize the separation and screwing of the cap and the tube body of the centrifuge tube, that is, the centrifuge tube capping device can replace manual labor to realize the separation and screwing of the centrifuge tube cap, which is beneficial to improving the work efficiency of medical staff.

[0076] The centrifuge tube capping device can enable the electric rotary gripper 600 to grip centrifuge tubes at different positions and transfer them to the clamping mechanism 400 by moving the three-axis manipulator along the X-axis, Y-axis, and Z-axis. In other embodiments of the present invention, the moving assembly 500 can be configured as other mechanisms capable of driving the electric rotary gripper 600 to move with multiple degrees of freedom, such as a six-axis manipulator, which is not limited herein.

All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.

[0078] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
