Description

Cover opening device, cover opening system and cover opening method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 4, 2023, with application number 202311651623.0 and application name “Opening device, opening system and opening method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of blood collection tubes, and in particular to a cover opening device, a cover opening system, and a cover opening method. Background Art

[0003] The vacuum blood collection tube opening function will be used in any field involving the use of blood sample testing, such as biological sample library, biochemical testing, clinical immunology testing, molecular diagnosis, blood diagnosis, blood glucose testing, liquid biopsy, drug testing, clinical trials, etc.

[0004] Uncapping of blood collection tubes refers to removing the sealing cap of the blood collection tube to be tested in order to carry out subsequent testing. Since the vacuum inside the blood collection tube is negative pressure, it takes a certain amount of force for the staff to manually open the cap, which has low work efficiency and is prone to blood splashing in the blood collection tube, causing the risk of cross-contamination of samples. Since the material of the blood collection tube is glass, when the staff opens the cap, the tube mouth may be broken due to external force, and the broken tube mouth has the risk of scratching the skin and causing infection. In addition, the aerosols remaining in the blood collection tube will also pose a potential threat of biological contamination to the staff. Therefore, automatic uncapping of blood collection tubes has practical significance for biosafety.

[0005] Therefore, how to avoid the risk of cross contamination and infection caused by manual opening of the lid while improving the opening efficiency is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0006] In view of this, the object of the present application is to provide a lid opening device to avoid the risk of cross contamination and infection caused by manual lid opening, while improving the lid opening efficiency;

[0007] Another object of the present application is to provide a cover opening system having the above-mentioned cover opening device and a cover opening method using the above-mentioned cover opening device.

[0008] In order to achieve the above objectives, this application provides the following technical solutions:

[0009] In a first aspect, the present application provides a cover opening device, comprising:

[0010] An opening bottom plate, wherein the opening bottom plate has a material tube opening position;

[0011] The cover opening assembly includes a material tube clamping mechanism arranged at the material tube cover opening position, and a cover opening mechanism and an ejection mechanism arranged above the material tube cover opening position.

[0019] An elastic return member is used to drive the first clamping plate and the second clamping plate to maintain a clamping state. When the first clamping plate and the second clamping plate are in the clamping state, a cover space for accommodating the material cover is formed therebetween, and one side of the cover space is an inlet for the ejection end of the ejection mechanism to extend into, and the other side is an outlet for the material cover to detach.

[0020] In a possible implementation, the clamping device further includes a stop block provided on the clamping base and located between the first clamping plate and the second clamping plate;

[0021] When the cap removing module drives the cap clamping module to descend until the stop block contacts the material cap, the cap removing module stops outputting the descending action.

[0022] In one possible implementation, the surfaces of the claw portions of the first clamping plate and the second clamping plate facing the material cover are both guide slopes, and the distance between the guide slopes of the first clamping plate and the second clamping plate gradually decreases from away from the cover space to closer to the cover space, and the maximum distance between the guide slopes of the first clamping plate and the second clamping plate is greater than the diameter of the material cover.

[0023] In a possible implementation, the clamping jaw seat is provided with a quick-change mounting hole and a fastening hole communicating with the quick-change mounting hole;

[0024] The rotation output end of the clamping cover rotation device cooperates with the quick-change mounting hole, and a positioning hole communicating with the fastening hole is opened on the rotation output end, and the fastening hole and the positioning hole form a quick-change fixing hole;

[0025] The clamping jaw device further comprises a quick-change fixing shaft, and the quick-change fixing shaft cooperates with the quick-change fixing hole.

[0026] In a possible implementation, the ejection mechanism includes:

[0027] An ejector mounting plate is provided on the cover bottom plate;

[0028] an ejection drive device, disposed on the ejection mounting plate, wherein an ejection end of the ejection drive device is capable of moving between a first position and a second position;

[0029] The ejection block is arranged at the ejection end of the ejection drive device. When the ejection end of the ejection drive device extends to the first position, the ejection block ejects the material cover removed by the clamping cover module.

[0030] In one possible implementation, the material tube clamping mechanism includes:

[0031] Clamping drive device;

[0032] A transmission screw, the clamping drive device drives the transmission screw to rotate, and the transmission screw has a first threaded portion and a second threaded portion with opposite rotation directions;

[0033] a sliding guide rail arranged parallel to the transmission screw;

[0034] The first clamping block and the second clamping block are respectively arranged on both sides of the material tube opening position, and both are slidably engaged with the sliding guide rail.

[0040] The decapping device provided in this application, when decapping a material tube, simply places the material tube in the decapping position. The material tube clamping mechanism clamps the material tube to be decapped, and the capping module grips the material cap of the material tube. The capping module then rises with the cap removal module. Since the material tube is clamped by the material tube clamping mechanism and cannot rise with it, only the material cap rises with the capping module, achieving the separation of the material cap. After the material cap is separated from the material tube, the ejection mechanism ejects the material cap removed by the capping module, allowing the capping module to grip the material cap of the next material tube. This application requires only the operator to place the decapped material tube in the decapping position to quickly decap, eliminating the need for manual decapping. This avoids the risk of sample spillage from the material tube due to unstable manual decapping force, which could lead to cross-contamination, and also avoids the risk of infection caused by skin scratches caused by broken material tubes. Furthermore, the decapping device used in this application is more efficient than manual decapping.

DETAILED DESCRIPTION

[0077] One aspect of the present application is to provide a lid opening device to avoid the risk of cross contamination and infection caused by manual lid opening, while improving the lid opening efficiency;

[0078] Another aspect of the present application is to provide a cover opening system having the above-mentioned cover opening device and a cover opening method using the above-mentioned cover opening device.

[0079] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0080] The embodiment of the present application discloses a capping device for replacing manual labor to perform capping operations on a material tube. It should be noted that the material tube can be a blood collection tube or other tubes with capping requirements.

[0081] As shown in Figures 3-5, the cover opening device disclosed in the embodiment of the present application includes a cover opening base plate 101 and a cover opening assembly. The cover opening base plate 101 has a material tube cover opening position, and the cover opening assembly is arranged at the material tube cover opening position for opening the material tube 401 placed at the material tube cover opening position.

[0082] The lid opening assembly includes a tube clamping mechanism 150 disposed at the tube opening position, and a lid opening mechanism and ejection mechanism 140 disposed above the tube opening position. The tube clamping mechanism 150 is used to clamp the tube 401 at the tube opening position to secure the tube 401 to be opened, preventing the tube 401 from moving during the opening process and affecting the opening process.

[0083] The lid opening mechanism includes a lid clamping module 130 for clamping the lid of the material tube 401 and a lid removal module 120 for raising and lowering the lid clamping module 130. The lid removal module 120 drives the lid clamping module 130 downward to clamp the bottom edge of the lid of the material tube 401, and then drives the lid clamping module 130 upward to remove the lid from the tube 401. The ejection mechanism 140 is used to eject the lid removed by the lid clamping module 130, allowing the lid clamping module to clamp the lid of the next material tube 401.

[0084] In summary, the capping device provided by the present application, when performing the capping operation on the material tube 401, only needs to place the material tube 401 in the capping position, and the material tube clamping mechanism 150 clamps the material tube 401 to be opened. The capping module 130 then clamps the material cap of the material tube 401. The capping module 130 is then driven upward by the cap removal module 120. Since the material tube 401 is clamped by the material tube clamping mechanism 150 and cannot rise with it, only the material cap rises with the capping module 130, thus achieving the separation of the material cap. After the material cap is separated from the material tube 401, the ejection mechanism 140 can eject the material cap removed by the capping module 130, so that the capping module 130 can clamp the material cap of the next material tube 401. The present invention only requires the operator to place the material tube 401 with the material cap in the material tube opening position to quickly open the cap, without manual opening. This avoids the risk of sample spillage from the material tube 401 due to unstable manual opening force, cross-contamination of samples, and infection caused by scratches on the skin caused by the material tube 401. Moreover, the present invention uses a capping device to open the cap, which, compared with manual opening, can avoid the problem of insufficient operator strength and inability to open the cap quickly, thereby improving work efficiency.

[0085] In a specific embodiment of the present application, the cover clamping module 130 includes a cover clamping mounting plate 132, a cover clamping rotating device 131, and a clamping claw device 133. The cover clamping mounting plate 132 is connected to the lifting output end of the cover removal module 120, that is, the cover removal module 120 can control the lifting action of the cover clamping mounting plate 132.

[0086] The clamping cover rotating device 131 is arranged on the clamping cover mounting plate 132. The clamping cover rotating device 131 can be a motor as long as it can output rotation. The clamping claw device 133 is connected to the rotation output end 1311 of the clamping cover rotating device 131 (as shown in Figure 6). When the clamping cover rotating device 131 is a motor, the clamping claw device 133 is connected to the output shaft of the clamping cover rotating device 131 to drive the clamping claw device 133 to rotate.

[0087] The clamping device 133 includes openable and closable jaws for gripping the material cover. When the jaws are open, the material cover of the feed tube 401 can enter. When the jaws are closed, the material cover is gripped, so that when the clamping device 133 moves upward, the material cover and the jaws cannot separate, thereby driving the material cover upward to separate the material cover from the tube body of the feed tube 401.

[0088] As shown in Figures 6 and 7, the clamping device 133 includes a clamping claw seat 1331, a clamping claw, and an elastic reset member 1335. The clamping claw seat 1331 is connected to the rotation output end 1311 of the clamping cover rotating device 131, and the clamping claw seat 1331 provides a mounting base for the clamping claw and the elastic reset member 1335.

[0089] The clamping jaws include a first clamping plate 1333 and a second clamping plate 1334. The first ends of the first and second clamping plates 1333 and 1334 are hinged to the clamping jaw base 1331 via a hinge axis, allowing the first and second clamping plates 1333 and 1334 to rotate about their hinge axis. When the second ends of the first and second clamping plates 1333 and 1334 move away from each other, the clamping jaws open; correspondingly, when the second ends of the first and second clamping plates 1333 and 1334 move toward each other, the clamping jaws close. The second ends of the first and second clamping plates 1333 and 1334 each have a claw portion 1336 formed thereon for contact with the bottom edge of the material cover. When the clamping jaws are closed, the claw portion 1336 contacts the bottom edge of the material cover, allowing the cover to be removed by lifting it upward.

[0090] To ensure that the clamping jaws remain in the closed position, and to prevent the claws 1336 of the first clamping plate 1333 and the second clamping plate 1334 from moving away from each other and disengaging from the cover when lifting, thus causing the cover to fail to open, an elastic return member 1335 is added in this embodiment. The elastic return member 1335 is used to drive the first clamping plate 1333 and the second clamping plate 1334 to maintain the clamping state. Specifically, the elastic reset member 1335 is a torsion spring, which can be mounted on the hinge shaft of the first clamping plate 1333 and the second clamping plate 1334. One elastic arm of the torsion spring of the first clamping plate 1333 abuts against the clamping claw seat 1331, and the other elastic arm abuts against the first clamping plate 1333; accordingly, one elastic arm of the torsion spring of the second clamping plate 1334 abuts against the clamping claw seat 1331, and the other elastic arm abuts against the second clamping plate 1334. Under the reset action of the torsion spring, the claw parts 1336 of the first clamping plate 1333 and the second clamping plate 1334 are ensured to swing in the direction of approaching each other, so as to keep the first clamping plate 1333 and the second clamping plate 1334 in a clamped state. It should be noted that the elastic return member 1335 can also be a tension spring, the two ends of which are respectively connected to the first clamping plate 1333 and the second clamping plate 1334, and can also enable the claw parts 1336 of the first clamping plate 1333 and the second clamping plate 1334 to swing towards each other and remain in a clamping state.

[0091] When the first and second clamping plates 1333 and 1334 are in a clamped state, a cover space 1337 is formed between them to accommodate the cover. The width of cover space 1337 should be greater than the diameter of the cover so that the cover can fit within it. The distance between the claws 1336 should be less than the diameter of the cover so that the claws 1336 can abut against the bottom edge of the cover. One side of cover space 1337 serves as an inlet for the ejection end of ejection mechanism 140 to extend into, and the other side serves as an outlet for the cover to be removed from. Specifically, the ejection end of ejection mechanism 140 extends from the inlet of cover space 1337 to eject the cover from the outlet of cover space 1337.

[0092] To ensure compatibility with tubes 401 of varying heights, in this embodiment, the gripper assembly 133 further includes a stopper 1332 disposed within the gripper base 1331 and positioned between the first and second clamping plates 1333 and 1334. When the cap removal module 120 drives the cap clamping module 130 downward, the cap of the tube 401 extends into the cap-receiving space 1337 between the first and second clamping plates 1333 and 1334, continuing to descend with the cap clamping module 130 until the stopper 1332 contacts the cap. At this point, the cap removal module 120 recognizes that the stopper 1332 has contacted the cap and ceases its downward movement. It should be noted that if the power output device of the cap removal module 120 is a motor, contact between the stopper 1332 and the cap can be detected using a motor encoder. Alternatively, contact between the stopper 1332 and the cap can be detected using a pressure sensor. As long as contact between the stopper 1332 and the cap can be detected, it will suffice. This embodiment can automatically adjust the descending height of the clamping cover module 130 according to the height of the material tube 401 by identifying the contact between the stop block 1332 and the material cover, so that adaptive opening of the material tubes with the same diameter but different heights can be achieved.

[0093] In order to enable the clamping jaws to open automatically when the clamping cover module 130 descends, in this embodiment, the surfaces of the clamping claws 1336 of the first clamping plate 1333 and the second clamping plate 1334 facing the material cover are both guide slopes, through which the characteristics of the wedge structure can be utilized to achieve the opening of the clamping jaws.

[0094] From away from the cover space 1337 to close to the cover space 1337, the distance between the guide slopes of the first clamping plate 1333 and the second clamping plate 1334 gradually decreases, that is, the distance between the two guide slopes facing one end of the material tube 401 is larger, and the maximum distance between the guide slopes of the first clamping plate 1333 and the second clamping plate 1334 is greater than the diameter of the material cover.

[0095] When the clamping cover module 130 descends, the claw portion 1336 of the first clamping plate 1333 and the second clamping plate 1334 gradually approach the material tube 401, and the material tube 401 first contacts the maximum distance of the guiding slope of the claw portion 1336. Under the action of the guiding slope, as the clamping cover module 130 continues to descend, the claw portion 1336 of the first clamping plate 1333 and the second clamping plate 1334 gradually swing away from each other until the material cover of the material tube 401 enters the cover space 1337 and contacts the stop block 1332. Under the action of the elastic return member 1335, the first clamping plate 1333 and the second clamping plate 1334 are driven to maintain a clamped state.

[0096] Those skilled in the art will appreciate that the gripping jaws 133 are detachably connected to the rotation output end 1311 of the clamping cap rotating device 131. Therefore, by replacing the gripping jaws 133, compatibility with material tubes 401 of different diameters and heights can be achieved. To achieve detachable connection between the gripping jaws 133 and the rotation output end 1311 of the clamping cap rotating device 131, the following solution may be employed.

[0097] The clamping jaw seat 1331 is provided with a quick-change mounting hole and a fastening hole connected to the quick-change mounting hole. The fastening hole and the quick-change mounting hole can usually be connected vertically. The rotating output end 1311 of the clamping cover rotating device 131 cooperates with the quick-change mounting hole, and the rotating output end 1311 is provided with a positioning hole connected to the fastening hole. When assembling the clamping jaw device 133, the rotating output end 1311 can be inserted into the quick-change mounting hole on the clamping jaw seat 1331. At this time, it is necessary to ensure that the angle of the rotating output end 1311 inserted into the quick-change mounting hole is ensured so that the fastening hole and the positioning hole are connected. For ease of understanding, the connected fastening hole and positioning hole are defined as a quick-change fixing hole.

[0098] The clamping device 133 also includes a quick-change fixing shaft 1338, which cooperates with the quick-change fixing hole. The quick-change fixing shaft 1338 can be a bolt or a positioning pin. When the quick-change fixing shaft 1338 is a positioning pin, both the fastening hole and the positioning hole can be clear holes. The fastening hole can be made to pass through the clamping device 1331. The quick-change fixing shaft 1338 is passed through the quick-change fixing hole. The end of the quick-change fixing shaft 1338 passing through the quick-change fixing hole is locked with a locking pin to complete the installation of the clamping device 133.

[0099] When quick-change fixing shaft 1338 is a bolt, the fastening hole is connected to the quick-change fixing hole. With the quick-change fixing hole as the boundary, the fastening hole on one side of the quick-change fixing hole is a plain hole, the fastening hole on the other side is a threaded hole, and the positioning hole is a plain hole. After the fastening holes and the positioning holes are connected, quick-change fixing shaft 1338 can be sequentially passed through the plain portion of the fastening hole and the positioning hole. Then, quick-change fixing shaft 1338 can be rotated so that the quick-change fixing shaft 1338 is threadedly engaged with the threaded portion of the fastening hole, thereby completing the installation of the clamping device 133.

[0100] In a specific embodiment of the present application, the opening device may also include a scanning module (not shown) for scanning the barcode on the material tube to replace manual scanning. A barcode is printed or pasted on the tube wall of the material tube 401, and the scanning module is set near the material tube opening position to scan the barcode on the material tube 401 at the material tube opening position. If the scanning module is able to scan the barcode on the material tube 401, the subsequent opening action can continue; if the scanning module does not scan the barcode on the material tube, before the material tube clamping mechanism 150 clamps the material tube 401, the clamping cover rotating device 131 drives the material tube 401 to rotate until the scanning module scans the barcode on the material tube. The material tube clamping mechanism 150 then clamps the material tube 401 and the subsequent opening action is performed. The present application can realize the placement of the material tube 401 without any direction requirements, and can also realize the barcode scanning function, avoiding the problem of barcode scanning failure caused by manual placement errors.

[0101] As shown in Figures 4 and 5, in this embodiment, the ejection mechanism 140 includes an ejection mounting plate 142, an ejection drive device 141, and an ejection block 143. The ejection mounting plate 142 is mounted on the cover base plate 101, and the ejection drive device 141 is mounted on the ejection mounting plate 142. The ejection drive device 141 can be a linear motor, a pneumatic cylinder, or other device, and its ejection end can move between a first position and a second position.

[0102] The ejection block 143 is mounted on the ejection end of the ejection drive 141. When the ejection end of the ejection drive 141 extends to the first position, the ejection block 143 ejects the cover removed by the cover clamping module 130. After ejecting the cover, the ejection end of the ejection drive 141 retracts to the second position to avoid interfering with the opening of the cover of the next tube 401.

[0103] It should be noted that the feed tubes 401 are typically mounted on the feed tube carrier 400, with multiple feed tubes 401 mounted on each feed tube carrier 400. The feed tubes 401 are arranged along the extension direction of the feed tube carrier 400, with relatively small gaps between them. To prevent adjacent feed tubes 401 from interfering with the lowering of the clamping jaws, the cover-turning device 131 is used to rotate the clamping jaws to an angle where the first clamping plate 1333 and the second clamping plate 1334 are positioned on opposite sides of the feed tube carrier 400 before the clamping jaws are lowered. After the clamping jaws complete the cover-opening action and rise above the feed tube 401, avoiding interference with the feed tube 401, the cover-turning device 131 rotates the clamping jaws to align the entrance of the cover-receiving space 1337 with the ejection end of the ejection mechanism 140 (typically achieved by rotating them 90°), facilitating the ejection of the feed tube.

[0104] Furthermore, the ejection mechanism 140 also includes an origin switch 145 and a trigger plate 144. The origin switch 145 is mounted on the ejection mounting plate 142, and the trigger plate 144 is fixed to the ejection block 143 or the ejection end of the ejection drive 141. When the ejection end of the ejection drive 141 retracts to the second position, the trigger plate 144 triggers the origin switch 145. The origin switch 145 is used to mark the second position of the ejection end of the ejection drive 141. After the origin switch 145 is triggered, the ejection end of the ejection drive 141 stops operating and retracts to the second position.

[0105] In a specific embodiment of the present application, the tube clamping mechanism 150 includes a clamping drive 151, a transmission screw 155, a sliding guide 156, a first clamping block 153, and a second clamping block 154. The clamping drive 151 can be a motor or other drive device capable of outputting rotation.

[0106] The clamping drive 151 rotates a drive screw 155, which has a first threaded portion and a second threaded portion that rotate in opposite directions. A sliding guide 156 is arranged parallel to the drive screw 155. A first clamping block 153 and a second clamping block 154 are respectively positioned on either side of the tube opening position and slidably engage with the sliding guide 156. The first clamping block 153 engages with the first threaded portion, while the second clamping block 154 engages with the second threaded portion. The first and second clamping blocks 153, 154 are used to clamp the tube in the tube opening position. Because the first and second clamping blocks 153, 154 slidably engage with the sliding guide 156, when the drive screw 155 rotates, the first and second clamping blocks 153, 154 cannot rotate with the drive screw 155 and can only move along the sliding guide 156.

[0107] When the clamping drive device 151 drives the transmission screw 155 to rotate, the first clamping block 153 and the second clamping block 154 can be controlled to move closer to each other or move away from each other according to the different rotation directions of the transmission screw 155, thereby achieving the clamping and loosening of the material tube 401.

[0108] Specifically, the clamping drive device 151 can drive the transmission screw 155 to rotate through the clamping transmission belt 152 (in order to ensure sufficient torque, a synchronous belt can be selected as the clamping transmission belt 152). A clamping driving wheel is provided on the output shaft of the clamping drive device 151, and a clamping driven wheel is provided on the transmission screw 155. The clamping transmission belt 152 is respectively coordinated with the clamping driving wheel and the clamping driven wheel for transmission, so that the clamping drive device 151 and the transmission screw 155 can be set at different heights to facilitate space layout.

[0109] In a specific embodiment of the present application, the cover removal module 120 may include support guide rods 123, a cover removal mounting plate 122, and a cover removal lifting drive device 121. The first ends of the support guide rods 123 are disposed on the cover opening base plate 101. In this embodiment, there are two support guide rods 123. Of course, those skilled in the art can select the number and position of the support guide rods 123 according to their needs.

[0110] The cover clamping module 130 slidably engages the support guide rod 123, which can be arranged vertically to guide the lifting and lowering of the cover clamping module 130. A cover removal mounting plate 122 is mounted on the second end of the support guide rod 123. A cover removal and lifting drive 121 is mounted on this plate, with the lifting output of the cover removal and lifting drive 121 connected to the cover clamping module 130. The cover removal and lifting drive 121 can be a linear motor or a piston cylinder, such as a pneumatic cylinder.

[0111] To collect the removed material caps, in this embodiment, the lid opening device may further include a material cap flow channel 112 and a waste collection box. The material cap flow channel 112 is mounted on the lid opening base plate 101 via a flow channel support 111. The inlet of the material cap flow channel 112 is located on the path of the ejection mechanism 140 ejecting the material caps. After the ejection mechanism 140 ejects the material caps, the ejected material caps pass through the inlet of the material cap flow channel 112 and enter the material cap flow channel 112. The outlet of the material cap flow channel 112 is located above the waste collection box. The inlet height of the material cap flow channel 112 is higher than the outlet height, allowing the material caps to roll down the material cap flow channel 112 into the waste collection box under the action of gravity.

[0112] Referring to Figures 1 and 2 , the present application also discloses a lid opening system, comprising a base assembly 300, a material tube storage device 200, and a lid opening device 100. The material tube storage device 200 is disposed on the base assembly 300 and is used to store material tubes 401. The lid opening device 100 is the lid opening device 100 disclosed in the above embodiment, with the lid opening base plate 101 disposed on the base assembly 300. The lid opening system provided in this application, because it includes the aforementioned lid opening device 100, possesses all the technical effects of the aforementioned lid opening device 100, and will not be further described herein.

[0113] Referring to Figure 3 , further, the material tubes are mounted on a material tube carrier 400, which is equipped with multiple material tubes. A carrier guide 103 is provided on the lid opening base plate 101, and the material tube carrier 400 slidably engages with the carrier guide 103. The lid opening device 100 also includes a carrier drive assembly that drives the material tube carrier 400 along the carrier guide 103. In this embodiment, for example, one material tube carrier 400 can accommodate a total of 16 branch material tubes 401. The carrier drive assembly drives the material tube carrier 400 to slide along the carrier guide 103, sequentially pushing the 16 branch material tubes 401 on the material tube carrier 400 to the tube lid opening position for the lid opening operation.

[0114] Furthermore, the carriage drive assembly includes a carriage pulling drive device, a hook guide rail 102 and a carriage hook 104. The carriage pulling drive device and the hook guide rail 102 are both arranged on the opening bottom plate 101, and the hook guide rail 102 is arranged parallel to the carriage guide rail 103.

[0115] In this embodiment, the carrier pulling drive device includes a carrier pulling motor 105, a driven support 107, and a carrier pulling transmission belt 106. The output shaft of the carrier pulling motor 105 is provided with a carrier pulling driving wheel, the driven support 107 is rotatably provided with a carrier pulling driven wheel, and the carrier pulling transmission belt 106 is respectively engaged with the carrier pulling driving wheel and the carrier pulling driven wheel.

[0116] The carrier hook 104 slidably engages with the hook guide rail 102. One end of the tube carrier 400 has a mounting slot, and the carrier hook 104 has a hook that engages with the mounting slot. The carrier traction drive device is used to drive the carrier hook 104 along the hook guide rail 102. The carrier hook 104 can be fixed to the carrier traction transmission belt 106. When the carrier traction motor 105 outputs power, the carrier traction transmission belt 106 begins to move, thereby driving the carrier hook 104 along the hook guide rail 102.

[0117] As shown in FIG2 , the tube storage device 200 further includes a tube storage support plate 201 and a plurality of parallel storage rails 2011 disposed on the tube storage support plate 201. The tube carriers 400 are arranged on the tube storage support plate 201 by slidingly engaging with the storage rails 2011. FIG2 shows six storage rails 2011, so the tube storage device 200 can accommodate 96 tubes 401.

[0118] The base assembly 300 includes a support base 301 and a cover opening device guide rail 302 provided on the support base 301 . The cover opening base plate 101 slides with the cover opening device guide rail 302 to adjust the carrier guide rail 103 and one of the storage guide rails 2011 to be in the same straight line.

[0119] Taking the perspective shown in FIG2 as an example, the driving device first drives the cover opening base plate 101 to slide along the cover opening device guide rail 302, and slides until the carrier guide rail 103 exceeds the first storage guide rail 2011, and then the carrier hook 104 moves along the hook guide rail 102 to one end close to the storage guide rail 2011, and then drives the carrier guide rail 103 to slide in the direction of the first storage guide rail 2011. At this time, the hook of the carrier hook 104 is just hooked on the hook groove of the material tube carrier 400 on the first storage guide rail 2011, realizing the carrier hook. The claw 104 is connected to the material tube carrier 400, and then the carrier hook claw 104 pulls the material tube carrier 400 from the storage guide rail 2011 to the carrier rail 103, and moves the first branch material tube 401 on the material tube carrier 400 to the material tube opening position, and after all 16 branch material tubes 401 on the material tube carrier 400 are opened in turn, the carrier hook claw 104 pushes the material tube carrier 400 to the corresponding storage guide rail 2011, and then processes the material tube carrier 400 on the second storage guide rail 2011 according to the above steps.

[0120] Specifically, the storage guide rail 2011 is parallel to the carrier guide rail 103 , and the cover opening device guide rail 302 is perpendicular to the storage guide rail 2011 .

[0121] In a specific embodiment of the present application, the tube storage device 200 further includes a transfer rail 202 and a transfer drive device. The transfer rail 202 is disposed on a support base 301, and the tube storage support plate 201 slidably engages with the transfer rail 202. The transfer drive device is disposed on the support base 301 and is configured to drive the tube storage support plate 201 to slide along the transfer rail 202, thereby transferring the tubes on the tube storage support plate 201 to the next workstation. It should be noted that the transfer drive device may include a transfer motor 203, a transfer support 204, and a transfer conveyor belt 205. A transfer driving wheel is disposed on the output shaft of the transfer motor 203, and a transfer driven wheel is rotatably disposed on the transfer support 204. The transfer conveyor belt 205 is respectively coupled to the transfer driving wheel and the transfer driven wheel. The tube storage support plate 201 may be connected to the transfer conveyor belt 205 via a fixed plate, so that the transfer conveyor belt 205 drives the tube storage support plate 201 to slide along the transfer rail 202. After all the tubes 401 on the tube storage support plate 201 have been opened, the tube storage support plate 201 can be driven to move rightward to enter the pipetting mechanism for detection (96 tubes 401 can be opened without contact).

[0122] The present application also discloses a method for opening a cover, which uses the opening device of any of the above embodiments to perform an opening operation, including a preparation step and an opening step;

[0123] The preparation step is to transfer the tube carrier carrying the tube to the tube cover opening position. Specifically, the tube carrier can be manually placed in the tube cover opening position or pulled to the tube cover opening position by a carrier drive assembly.

[0124] The opening steps include:

[0125] 1) The tube to be opened on the tube carrier is clamped by the tube clamping mechanism to fix the tube to be opened, so as to prevent the tube from rising when opening the cover, resulting in failure to open the cover successfully.

[0126] 2) The cap removal module drives the cap clamping module downward until it clamps the tube cap. The cap removal module then drives the cap clamping module upward to remove the cap. As the cap removal module drives the cap clamping module downward, the tube cap pushes open the clamping jaws, allowing the cap to enter the cap-receiving space. The claws then press against the bottom edge of the cap, clamping it to the tube. The cap removal module then drives the cap clamping module upward. Because the tube is secured by the tube clamping mechanism, it cannot rise with it, effectively separating the cap from the tube body.

[0127] 3) The ejection mechanism ejects the cover removed by the cover clamping module. The cover clamping rotating device drives the clamping claw device to rotate so that the entrance of the cover holding space is aligned with the ejection end of the ejection mechanism. The cover removed by the cover clamping module is then ejected by the ejection mechanism.

[0128] The cover opening method provided in the present application has all the technical effects of the above-mentioned cover opening device because it adopts the above-mentioned cover opening device. It will not be described in detail herein. For the specific cover opening process, please refer to the solution disclosed in the above-mentioned embodiment.

[0129] Furthermore, the decapping method may further include a detection step between the preparation step and the decapping step, the detection step including:

[0130] 1) Scan the barcode on the material tube. When the barcode on the material tube is scanned, the cover opening step is executed; when the barcode on the material tube is not scanned, it means that the barcode on the material tube does not correspond to the scanning module. The cover removal module drives the cover clamping module to move downward until the cover clamping module clamps the material cover of the material tube. Then, the cover removal module drives the cover clamping module to move upward a preset distance, that is, before the material tube clamping mechanism clamps the material tube, the entire material tube is lifted to separate from the material tube carrier.

[0131] 2) The clamping cover module drives the material tube to rotate until the barcode on the material tube is scanned, that is, the barcode on the material tube is rotated to a position corresponding to the scanning module.

[0132] 3) The cap removal module drives the cap clamping module to move downward to the initial position, that is, to the tube falling into the tube carrier, and the cap opening step is performed. The cap opening step is the same as the cap opening step disclosed in the above embodiment and will not be repeated here.
