[0042] In the related art, test tube specimens can be sealed and preserved by sealing the opening of the test tube. When testing the sample in the test tube, the sealing film on the test tube needs to be torn off so that the instrument can test the sample in the test tube. At present, it is impossible to use mechanical automation equipment to tear off the test tube film, resulting in high labor costs and low test tube film tearing efficiency.

[0043] The present invention provides a test tube film peeling device 100 .

[0044] See also Figures 1 to 5 In one embodiment of the present invention, the test tube film tearing device 100 includes a body 10, a test tube clamping device 20 and a film tearing device 30; the body 10 has a film tearing station for placing the test tube 200, and the opening cover of the test tube 200 is provided with a sealing film; the test tube clamping device 20 is arranged at the film tearing station, and is used to cooperate with the test tube 200 in a limited position; the film tearing device 30 includes a driving mechanism 32 and a clamping mechanism 31, the driving mechanism 32 is arranged on the body 10, and is transmission-connected with the clamping mechanism 31, and the clamping mechanism 31 is used to clamp or release the sealing film; the driving structure 32 is used to drive the clamping mechanism 31 to move toward the test tube clamping device 20 so that the clamping mechanism 31 clamps the sealing film of the test tube, and is used to drive the clamping mechanism 31 to move away from the test tube clamping device 20 so that the clamping mechanism 31 drives the sealing film to leave the test tube.

[0045] In some embodiments, a transfer device 50 may be provided on the body 10, and the transfer device 50 may be provided relative to the film sealing station. With such a configuration, the test tube 200 may be supported and moved by the transfer device 50, so as to transfer the test tube 200 to the test tube clamping device 20 at the film sealing station of the body 10. The transfer mechanism may be specifically provided as a rotary transfer mechanism such as a circular stage, etc., or may be provided as a linear transfer mechanism such as a transmission line, etc., which is not limited here. Of course, in other embodiments, the test tube film sealing device 100 may also be provided with a test tube carrier at the film sealing station, so as to place the test tube 200 to be torn off the film through the test tube carrier, and the test tube carrier may be provided as, but not limited to, a test tube rack, etc., which is not limited here.

[0046] The test tube clamping device 20 can be used to place the test tube 200. The opening of the test tube 200 and the sealing film at the opening can be exposed above the test tube clamping device 20, so that the clamping mechanism 31 of the film tearing device 30 can be clamped and cooperated with the sealing film. The test tube clamping device 20 can also be used to limit the parts of the test tube 200 other than the sealing film to improve the position stability of the test tube 200 during the film tearing process. For example, the test tube clamping device 20 can be limited and cooperated with the bottom, side wall and other parts of the test tube 200; with such a configuration, when the test tube 200 is being torn off, by keeping the test tube clamping device 20 in a clamped state, it can be prevented that the test tube 200 is lifted by the film tearing device 30 and slips or deviates, thereby affecting the film tearing effect of the sealing film.

[0047] There are many ways in which the test tube clamping device 20 can be used to limit the test tube 200. For example, in a feasible embodiment, the test tube clamping device 20 can be provided with a clamping mechanism 21 such as a clamping claw 211 to clamp and limit the test tube 200 through a mechanical structure. Of course, the test tube clamping device 20 can also limit the test tube 200 through other limiting methods such as vacuum adsorption, etc. The specific implementation method can be set according to actual needs and is not limited here.

[0048] It should be noted that, in the technical solution of the present invention, the clamping mechanism 21 of the test tube clamping device 20 may not only be arranged at the film tearing station to clamp the test tube to be torn off. In a feasible embodiment, a plurality of test tube placement positions may be provided on the transfer device 50 to place a plurality of test tubes 200 at a time, and the plurality of test tubes 200 may be transferred to the film tearing station in sequence. Correspondingly, the test tube clamping device 20 may also include a plurality of clamping mechanisms 21, each of which is arranged at a test tube placement position. With such an arrangement, the plurality of test tubes 200 on the transfer device 50 can be simultaneously limited and clamped by the plurality of clamping mechanisms 21 of the test tube clamping device 20.

[0049] In a feasible embodiment, the transfer device 50 can be set as a carrier 51, and the carrier 51 can be provided with a first limiting hole for plugging and cooperating with the bottom of the test tube 200. There can be multiple first limiting holes, and the multiple first limiting holes are arranged in sequence along the circumference of the avoidance hole 511. Among them, a clamping structure can be set corresponding to each first limiting hole, and the clamping structure can be but not limited to being set as an elastic limiting member such as a lifting and shrinking buckle, a spring sheet, etc. By setting the clamping structure, the size of the first limiting hole can be limited so that the test tube 200 is clamped in the first limiting hole. In addition, by specifically configuring the clamping structure as an elastic limiting member, it is also beneficial to enable the carrier 51 to cooperate with the test tubes of different apertures through the first limiting hole, thereby facilitating the applicability of the transfer device 50.

[0050] The film tearing device 30 includes a driving mechanism 32 and a clamping mechanism 31 for clamping and cooperating with the sealing film. The film tearing device 30 can drive the clamping mechanism 31 to move through the driving mechanism 32. In some embodiments, the film tearing device 30 can be provided with only a single driving component, which can be specifically set as a linear driving component. The test tube 200 is placed vertically, and the clamping mechanism 31 is arranged directly above the test tube clamping device 20 and is connected to the linear driving component. With such a configuration, the clamping mechanism 31 can be driven by the linear driving component to move down to the opening of the test tube 200 to clamp the sealing film at the opening of the test tube 200, and then the clamping mechanism 31 is moved upward relative to the test tube 200 to drive the sealing film to be separated from the test tube 200.

[0051] Specifically, the clamping mechanism 31 can move toward the test tube clamping device 20 to move to the opening position of the test tube 200 and clamp the sealing film at the opening of the test tube 200; after the clamping mechanism 31 clamps the sealing film, the clamping mechanism 31 can move away from the test tube clamping device 20 along the extension direction of the test tube 200 to take the sealing film of the test tube 200 away from the test tube 200, thereby realizing automatic film tearing of the test tube 200 to improve the efficiency of film tearing of the test tube 200.

[0052] In other embodiments, the driving mechanism 32 of the film tearing device 30 may be provided with two or more driving components, one of the driving components of the driving mechanism 32 may be specifically configured as a linear driving component, which is used to drive the clamping mechanism 31 to move along the extension direction of the test tube 200, to move to the opening of the test tube 200 and dock with the sealing film, and to be able to move away from the test tube 200 along the extension direction of the test tube 200 to move the sealing film away from the opening of the test tube 200; the remaining driving components of the driving mechanism 32 may be one or more, which are used to drive the clamping mechanism 31 to move toward or away from the test tube clamping device 20. Such a configuration can improve the movement flexibility of the film tearing device 30, so that after tearing the sealing film, the sealing film can be moved to other positions of the test tube film tearing equipment 100 for recovery.

[0053] See also Figure 3 and Figure 4 In an embodiment of the present invention, the clamping mechanism 31 includes a seat assembly 313, a pressure block assembly 311 and a clamping assembly 312, and the seat assembly 313 is transmission-connected with the driving mechanism 32; the pressure block assembly 311 is arranged on the seat assembly 313, and is used to press on the opening of the test tube 200 to abut against the top surface of the sealing film; the clamping assembly 312 can be raised and lowered on the seat assembly 313, and can be opened and closed below the pressure block assembly 311, so as to have a clamping state surrounding the side of the test tube 200 and a releasing state detached from the test tube 200; in the clamping state, the clamping assembly 312 is used to move toward the pressure block assembly 311, so that the clamping assembly 312 and the pressure block assembly 311 cooperate to clamp the sealing film.

[0054] In this embodiment, by making the clamping assembly 312 escalable and arranged on the seat assembly 313, the clamping assembly 312 can be moved toward or away from the pressing block assembly 311 to achieve clamping or releasing of the sealing film. In some embodiments, the clamping assembly 312 includes a lifting mechanism 3121 and a clamping jaw mechanism 3122, and the lifting mechanism 3121 and the clamping jaw mechanism 3122 are transmission-connected, and the clamping jaw mechanism 3122 can be opened and closed to switch its clamping state and release state through the opening and closing movement of the clamping jaw mechanism 3122. Among them, the clamping jaw mechanism 3122 can be specifically configured as a pneumatic clamping jaw, which has two clamping members arranged opposite to each other, and the opening and closing stroke of the pneumatic clamping jaw can be, but is not limited to, set to 180°.

[0055] Specifically, the two clamping members of the clamping mechanism 3122 can move toward each other to put the pneumatic clamping member in a clamped state, so that the two clamping members can be enclosed and clamped on the periphery of the test tube 200, so that when the clamping assembly 312 moves toward the open end of the test tube 200 along the extension direction of the test tube 200, the sealing film covering the test tube 200 can be turned up, and then the upper end surface of the clamping mechanism 3122 of the clamping assembly 312 and the lower end surface of the pressing block assembly 311 can cooperate to clamp the turned-up sealing film. The two clamping members can also move in opposite directions to put the pneumatic clamping member in a released state. It can be understood that by making the clamping mechanism 3122 surround the periphery of the test tube 200 in the clamped state to achieve a full circle of covering the test tube 200, it is beneficial to ensure the turning up and clamping effect of the clamping mechanism 31 on the sealing film.

[0056] Of course, the technical solution of the present invention is not limited thereto. In other embodiments, when the clamping mechanism 3122 is in the clamping state, the two clamping members may only cover and clamp the local position of the test tube 200, so as to drive the sealing film to be torn off the test tube 200 as a whole by clamping and cooperating with the local position of the sealing film. The specific implementation method can be set according to actual needs and is not limited here.

[0057] Specifically in the present embodiment, during the tearing process of the sealing film, the clamping mechanism 3122 of the clamping assembly 312 is first kept in a released state and kept at a certain distance from the pressing block assembly 311. At this time, the clamping mechanism 31 can be driven by the driving mechanism 32 to move toward the test tube 200 as a whole, so that the lower end surface of the pressing block assembly 311 is pressed against the opening of the test tube 200, and the two clamping members of the clamping mechanism 3122 are arranged at intervals on the peripheral side of the test tube 200; then, the two clamping members are moved toward each other to clamp on the peripheral side of the test tube 200, so that the clamping mechanism 3122 is kept in a clamped state. At this time, the sealing film on the test tube 200 can be arranged between the pressing block assembly 311 and the clamping assembly 312; then, the lifting mechanism 31 is lifted. The lowering mechanism 3121 drives the clamping mechanism 3122 to move toward the pressing block assembly 311, so as to drive the sealing film between the pressing block assembly 311 and the clamping assembly 312 to flip up toward the pressing block assembly 311, and the flipped up sealing film can be clamped by the lower end surface of the pressing block assembly 311 and the upper end surface of the clamping mechanism 3122; finally, the clamping mechanism 31 can be driven by the driving mechanism 32 to move away from the test tube 200 as a whole, so that the pressing block assembly 311 and the clamping mechanism 3122 of the clamping assembly 312 can keep the sealing film clamped and move away from the test tube 200 synchronously, so that the sealing film can be torn off from the opening of the test tube 200, thereby realizing automatic film tearing of the test tube 200.

[0058] See also Figure 5 In an embodiment of the present invention, the pressing block assembly 311 includes a fixing member 3111, a pressing block 3112 and an elastic member 3113. The fixing member 3111 is arranged on the seat assembly 313; the pressing block 3112 is arranged at intervals below the fixing member 3111, and is used to abut against the top surface of the sealing film when the fixing member 3111 moves toward the test tube 200; the elastic member 3113 is arranged between the fixing member 3111 and the pressing block 3112, and the two ends of the elastic member 3113 are respectively connected to the fixing member 3111 and the pressing block 3112.

[0059] In this embodiment, by connecting the two ends of the elastic member 3113 to the fixing member 3111 and the pressing block 3112 respectively, the fixing member 3111 can make the pressing block 3112 elastically abut against the sealing film at the opening of the test tube 200 when the seat body assembly 313 moves toward the test tube clamping device 20, so that the lower end surface of the pressing block 3112 can fit well with the sealing film, thereby ensuring the pressing effect of the pressing block assembly 311 on the sealing film, and enabling the pressing block assembly 311 to stably cooperate with the clamping assembly 312 to clamp the sealing film.

[0060] In some embodiments, a first positioning hole may be provided on one side of the fixing member 3111 facing the pressing block 3112, and a second positioning hole may be provided on one side of the pressing block 3112 facing the fixing member 3111. The second positioning hole is arranged opposite to the first positioning hole, and the two ends of the spring are respectively limited to the first positioning hole and the second positioning hole. Such an arrangement is conducive to improving the position stability of the spring.

[0061] See also Figure 5 In an embodiment of the present invention, one of the fixing member 3111 and the pressing block 3112 is provided with a guide shaft 3112a extending in the up-down direction, the other of the fixing member 3111 and the pressing block 3112 is provided with a guide hole 3111a, at least part of the guide shaft 3112a is movably inserted into the guide hole 3111a, and the elastic member 3113 is sleeved on the guide shaft 3112a.

[0062] In this way, the guide hole 3111a can guide the guide shaft 3112a, thereby improving the matching stability between the fixing member 3111 and the pressing block 3112. Furthermore, the elastic member 3113 can be configured as a spring, and by sleeve-arranging the spring around the guide shaft 3112a, the positioning effect of the guide shaft 3112a on the spring can be utilized to further improve the position stability of the spring.

[0063] Specifically in this embodiment, a guide hole 3111a is provided on the fixing member 3111, one end of the guide shaft 3112a is connected to the pressing block 3112, and the other end is inserted into the guide hole 3111a of the fixing member 3111 and exposed at the end of the fixing member 3111 away from the pressing block 3112, and the guide shaft 3112a can be limited and fixed by a nut. A linear bearing can be provided in the guide hole 3111a, and the linear bearing is provided between the inner wall of the guide hole 3111a and the outer wall of the guide shaft 3112a, which is conducive to improving the movement stability of the guide shaft 3112a.

[0064] See also Figures 3 to 5 In an embodiment of the present invention, a negative pressure channel 3112b connected to the bottom surface of the pressing block 3112 is formed in the pressing block 3112, and the pressing block assembly 311 also includes a vacuum generator 3114, which is connected to the negative pressure channel 3112b and is used to form a negative pressure in the negative pressure channel 3112b so that the bottom surface of the pressing block 3112 can be adsorbed and cooperated with the sealing film.

[0065] In this embodiment, by setting a vacuum generator 3114 in the pressing block assembly 311, the lower end surface of the pressing block 3112 can have a vacuum adsorption function for the sealing film, which is beneficial to reduce the risk of the sealing film detaching from the clamping mechanism 31 during the process of transferring the sealing film.

[0066] Among them, one end of the negative pressure channel 3112b can be connected to the bottom of the pressing block 3112 through an adsorption hole, and one or more adsorption holes can be provided; the other end of the negative pressure channel 3112b is provided with a joint structure for connecting the vacuum generator 3114 to facilitate the installation and coordination of the pressing block 3112 and the vacuum generator 3114.

[0067] See also Figure 2 In an embodiment of the present invention, the film tearing device 30 also includes a detection mechanism 33, which is arranged on the side of the clamping mechanism 31 and is used to synchronously move into the top of the test tube clamping device 20 when the clamping mechanism 31 moves out of the top of the test tube clamping device 20.

[0068] Specifically, in this embodiment, the detection mechanism 33 has an initial position located at the side of the test tube clamping device 20 and a detection position located above the test tube clamping device 20, and the clamping mechanism 31 has a material clamping position located above the test tube clamping device 20 and a material discharge position located at the side of the test tube clamping device 20. In addition, the detection position of the detection mechanism 33 is arranged to coincide with the material clamping position of the clamping mechanism 31.

[0069] When the clamping mechanism 31 is in the clamping position, the clamping mechanism 31 can clamp the sealing film at the test tube 200, and in the process of the clamping mechanism 31 moving from its clamping position to the discharge position, the clamping mechanism 31 can maintain the clamping state of the sealing film to take the sealing film away from the position of the test tube 200. When the clamping mechanism 31 is in the discharge position, the clamping mechanism 31 can release the sealing film at the test tube 200, waiting to be reset to the clamping position to perform the next film tearing step. After the detection mechanism 33 moves from its initial position to the detection position, it can detect the test tube at the test tube clamping device 20 to determine whether there is a sealing film at the test tube 200.

[0070] The movement stroke of the detection mechanism 33 from its initial position to the detection position is the same as the movement stroke length of the clamping mechanism 31 from its clamping position to the discharge position. With such a configuration, when the film of the test tube 200 is torn off, the detection mechanism 33 can be synchronously moved to the top of the test tube clamping device 20 to detect whether the sealing film at the test tube 200 is torn off. By carrying out the film tearing process and the detection process at the same time, it is beneficial to improve the efficiency of film tearing detection. After the detection is completed, the clamping mechanism 31 can be moved back to the top of the test tube clamping device 20, and the detection mechanism 33 can be synchronously moved out of the top of the test tube clamping device 20 to wait for the next film tearing process and detection process.

[0071] In some embodiments, the detection mechanism 33 and the clamping mechanism 31 can be synchronously rotated under the drive of the same driving mechanism 32, then the initial position of the detection mechanism 33, the detection position of the detection mechanism 33, the clamping position of the clamping mechanism 31, and the discharge position of the clamping mechanism 31 can be equidistantly spaced in the circumferential direction of the driving mechanism 32. Alternatively, the detection mechanism 33 and the clamping mechanism 31 can also be synchronously translated under the drive of the same driving mechanism 32, then the initial position of the detection mechanism 33, the detection position of the detection mechanism 33, the clamping position of the clamping mechanism 31, and the discharge position of the clamping mechanism 31 can be equidistantly spaced in the straight line direction. Of course, the technical solution of the present invention is not limited to this, and the detection mechanism 33 and the clamping mechanism 31 can of course also be synchronously moved under the drive of different driving mechanisms, which is not limited here.

[0072] Optionally, the sealing film can be specifically set as an aluminum film, and the detection mechanism 33 can be correspondingly set as a metal sensor, so that the metal sensor can detect whether there is an aluminum film at the opening of the test tube 200, thereby realizing the detection of whether the sealing film at the mouth of the test tube 200 has been torn off. In other embodiments, the detection mechanism 33 can be set as a photo detection mechanism 33, etc., which can be set according to actual needs, and the present application does not limit the type of the detection mechanism 33.

[0073] See also Figure 1 and Figure 2 In the embodiment of the present invention, the test tube film tearing device 100 further includes a collecting device 40, which is disposed on the body 10 and forms a collecting chamber with a top opening. The collecting device 40 is used to be disposed opposite to the clamping mechanism 31 after the clamping mechanism 31 moves out of the test tube clamping device 20, so as to receive the sealing film released by the clamping mechanism 31. With such a configuration, the test tube film tearing device 100 can sequentially complete the sealing film tearing and sealing film recycling processes, which is conducive to improving the practicality and ease of use of the test tube film tearing device 100.

[0074] In some embodiments, the collecting device 40 may be a funnel structure as a whole, or a funnel structure may be provided at the opening of the collecting device 40. The cross-sectional area of ​​the funnel structure is gradually increased from bottom to top, so as to collect and gather the torn sealing film. Of course, the collecting device 40 may also be provided in a cylindrical body, a box body or other shapes, which are not limited here.

[0075] Furthermore, in a feasible embodiment, the spacing between the clamping mechanism 31 and the detection mechanism 33 is the same as the spacing between the collecting device 40 and the test tube clamping device 20, that is, the movement stroke of the detection mechanism 33 from its initial position on the side of the test tube clamping device 20 to the detection position above the test tube clamping device 20 is the same as the movement stroke length of the clamping mechanism 31 from the test tube clamping device 20 to the collecting device 40, so that the collecting device 40 can be arranged relative to the clamping mechanism 31 in the discharging position.

[0076] With such arrangement, when the clamping mechanism 31 moves from its clamping position above the test tube clamping device 20 to its discharging position on the side of the test tube clamping device 20, it can release the sealing film so that the sealing film falls into the collecting device 40 accordingly. At the same time, the detecting mechanism 33 can be synchronously moved to above the test tube of the test tube clamping device 20, thereby enabling the clamping mechanism 31 to complete the step of tearing the film of the test tube 200 and moving the torn sealing film to the collecting device 40, and the step of moving the detecting mechanism 33 to above the test tube clamping device 20 to detect whether the sealing film is torn off is performed synchronously, thereby achieving the effect of reducing motion waste when the test tube film tearing device 100 is working.

[0077] See also Figure 1 and Figure 3 In an embodiment of the present invention, the driving mechanism 32 includes a first driving component 321 and a second driving component 322. The first driving component 321 is connected to the clamping mechanism 31 for driving the clamping mechanism 31 to move up and down; the second driving component 322 is arranged on the body 10 and is connected to the first driving component 321 for driving the first driving component 321 to move horizontally, so as to drive the clamping mechanism 31 to move in or out of the top of the test tube clamping device 20 in the horizontal direction.

[0078] Among them, the first drive component 321 can be configured as a linear drive mechanism 32 such as a telescopic cylinder, a linear module, a screw drive mechanism 32, etc., so that the clamping mechanism 31 can move up and down relative to the test tube clamping device 20 in a translational manner, so that the clamping mechanism 31 can descend toward the test tube clamping device 20 to the opening position of the test tube 200 to clamp the sealing film on the test tube 200, and can rise and move away from the test tube clamping device 20 after clamping the sealing film to take the sealing film of the test tube 200 away from the test tube 200.

[0079] The second drive assembly 322 is used to drive the clamping assembly 312 to move in or out of the top of the test tube clamping device 20. In some embodiments, the second drive assembly 322 can be configured as a rotary drive mechanism 32 such as a rotary cylinder or a rotary motor, so that the first drive assembly 321 can drive the clamping mechanism 31 to move in or out of the top of the test tube clamping device 20 in a rotating manner. Of course, the embodiments of the present invention are not limited to this. In other embodiments, the second drive assembly 322 can also be configured as a linear drive mechanism 32 such as a telescopic cylinder, a linear module, a screw drive mechanism 32, so that the first drive assembly 321 can drive the clamping mechanism 31 to move in or out of the top of the test tube clamping device 20 in a translational manner, and its translation direction can be horizontal or inclined relative to the horizontal direction, which is not limited here. Alternatively, the second drive assembly 322 can include multiple drive mechanisms 32 to cooperate with the first drive assembly 321 to move, and the multiple drive mechanisms 32 can all be rotary drive mechanisms 32 or linear drive components, or they can be combined to form a rotary drive mechanism 32 or a linear drive component, which is not limited here.

[0080] See also Figures 1 to 4 In an embodiment of the present invention, the second driving assembly 322 has a rotating shaft extending in the up-down direction, and the clamping mechanism 31 and the detecting mechanism 33 are spaced apart in the circumferential direction of the second driving assembly 322 to rotate synchronously around the rotating shaft.

[0081] With such an arrangement, the space around the second drive component 322 can be fully utilized to arrange the clamping mechanism 31 and the detection mechanism 33. The second drive component 322 can drive the clamping mechanism 31 to rotate out from above the test tube clamping device 20 while driving the detection mechanism 33 to synchronously rotate into above the test tube clamping device 20, so as to realize the synchronous rotation of the two components of the clamping mechanism 31 and the detection mechanism 33 through the same drive structure.

[0082] Specifically in this embodiment, the clamping mechanism 31 and the detection mechanism 33 can be connected through two mounting arms and the second driving assembly 322 respectively. The angle between the two mounting arms can be set to a right angle or other angles, which is not limited here.

[0083] See also Figure 3 and Figure 4 In an embodiment of the present invention, the test tube film tearing device 100 further includes a transfer device 50 , which is disposed on the body 10 and is used to support the test tube 200 and transfer the test tube 200 to the test tube clamping device 20 .

[0084] The transfer device 50 can be specifically configured as a rotating transfer device 50 such as a ring stage 51, etc., or as a linear transfer device 50 such as an assembly line, etc., which is not limited here. The transfer device 50 is used to support the test tube 200, and transfer the test tube 200 to be torn off to the test tube clamping device 20 on the film tearing station, so that the test tube 200 can be placed adjacent to the film tearing device 30, and is limited in the film tearing station by the clamping mechanism 21 of the test tube clamping device 20; after the sealing film on the test tube 200 is torn off, the transfer device 50 can move the torn test tube 200 out of the film tearing station for subsequent inspection, and can make the next to-be-torn test tube 200 synchronously move into the film tearing station, thereby realizing continuous and automatic film tearing of multiple test tubes 200.

[0085] The clamping mechanism 21 of the test tube clamping device 20 is arranged at the film tearing station, and is used to limit the position of the test tube 200 other than the sealing film, so as to improve the position stability of the test tube 200 during the film tearing process. The clamping mechanism 21 can be specifically set as a pneumatic clamp. During the film tearing process of the test tube 200, by making the clamping mechanism 21 and the test tube 200 limit the position, it can be prevented that the test tube 200 is lifted by the film tearing device 30 and slips and deviates; after the test tube 200 completes the film tearing, the clamping mechanism 21 can release the test tube 200 that has completed the film tearing, so as to wait for the next test tube 200 that moves into the film tearing station to be clamped.

[0086] See also Figure 3 and Figure 4 In an embodiment of the present invention, the transfer device 50 includes a carrier 51 arranged in a ring shape, the carrier 51 is rotatably arranged on the body 10, and is surrounded by a avoidance hole 511, and the bottom of the test tube 200 is supported and limited on the carrier 51; the clamping mechanism 21 includes two clamping jaws 211, one of which is penetrated through the avoidance hole 511 to be exposed to the side of the test tube 200, and the two clamping jaws 211 can be opened and closed along the radial direction of the carrier 51.

[0087] With such arrangement, when the carrier 51 moves the test tube 200 to the preset film-tearing station, the two clamping jaws 211 of the clamping mechanism 21 can be arranged in alignment with the test tube 200, and at this time, the two clamping jaws 211 can be closed to clamp the test tube 200. When the two clamping jaws 211 are opened, the two clamping jaws 211 of the clamping mechanism 21 can be avoided in the rotation path of the carrier 51 and the test tube 200 thereon, so as to avoid the clamping mechanism 21 interfering with the operation of the transfer device 50, so that there is no need to move the clamping mechanism 21, and only the opening and closing movement of the clamping mechanism 21 can be controlled to form a good match with the carrier 51 and the test tube 200 thereon.

[0088] Of course, the technical solution of the present invention is not limited thereto. In other embodiments, the clamping mechanism 21 may also be movably disposed at the film-tearing station, so that the clamping mechanism 21 can be moved into or out of the film-tearing station. When the clamping mechanism 21 moves out of the film-tearing station, it can avoid the stage 51 and the test tube 200 thereon, so that the transfer device 50 can transfer the test tube 200 to a preset position; when the clamping mechanism 21 moves into the film-tearing station, it can align with the test tube 200 and complete the clamping and positioning of the test tube 200.

[0089] In some embodiments, a first limiting hole may be provided on the carrier 51 to be plugged with the bottom of the test tube 200. A plurality of first limiting holes may be provided, and the plurality of first limiting holes are sequentially spaced along the circumference of the avoidance hole 511. Furthermore, a limiting frame 512 may be provided above the carrier 51, the limiting frame 512 and the carrier 51 are spaced and coaxially arranged, and a plurality of second limiting holes are provided through the limiting frame 512, and each second limiting hole is arranged opposite to a first limiting hole to cooperate in limiting the test tube 200, which is beneficial to improving the position stability of the test tube 200. The two clamping claws 211 of the clamping mechanism 21 can extend between the limiting frame 512 and the carrier 51, and are used to clamp and limit the part of the test tube 200 exposed between the limiting frame 512 and the carrier 51.
