In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0042] In the related art, the test tube specimen can be sealed by sealing the opening of the test tube. When detecting the sample in the test tube, the sealing film on the test tube needs to be torn off so that the instrument can detect the sample in the test tube. At present, since the mechanical automatic equipment cannot be used to realize the test tube film tearing, the labor cost is high and the test tube film tearing efficiency is low.

[0043] The utility model provides a test tube film tearing equipment 100.

[0044] Please refer to Figures 1 to 5 In an embodiment of the present application, the test tube film tearing equipment 100 includes a machine body 10,

[0045] A test tube clamping device 20 and a film tearing device 30; The machine 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 in the film tearing station and is used for limiting cooperation with the test tube 200; The film tearing device 30 includes a driving mechanism 32 and a clamping mechanism 31, the driving mechanism 32 is arranged in the machine body 10 and is in transmission connection with the clamping mechanism 31, and the clamping mechanism 31 is used for clamping or releasing the sealing film; The driving mechanism 32 is used for driving the clamping mechanism 31 to move towards the test tube clamping device 20, so that the clamping mechanism 31 clamps the sealing film of the test tube, and is used for driving 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 separate from the test tube.

[0046] In some embodiments, the body 10 can be provided with a transfer device 50, and the transfer device 50 can be arranged relative to the sealing station. In this way, the test tube 200 can be supported and moved by the transfer device 50 to be transferred to the test tube clamping device 20 at the sealing station of the body 10. The transfer mechanism can be arranged as a rotary transfer mechanism such as a ring-shaped carrier, or can be arranged as a linear transfer mechanism such as a transmission line, which is not limited herein. Of course, in other embodiments, the test tube sealing device 100 can also be arranged with a test tube carrier at the sealing station to place the test tube 200 to be sealed. The test tube carrier can be arranged as a test tube rack, which is not limited herein.

[0047] The test tube clamping device 20 can be used to place the test tube 200, and the opening of the test tube 200 and the sealing film at the opening can be exposed above the test tube clamping device 20 to facilitate the clamping mechanism 31 of the film tearing device 30 to clamp the sealing film. The test tube clamping device 20 can also be used to limit the part 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 in cooperation with the bottom, side wall and other parts of the test tube 200. In this way, when the test tube 200 is torn, the test tube clamping device 20 can be kept in a clamped state to avoid the test tube 200 from being lifted by the film tearing device 30 and slipping, which affects the film tearing effect of the sealing film.

[0048] The test tube clamping device 20 can be used to limit the test tube 200 in various ways. For example, in one possible embodiment, the test tube clamping device 20 can be clamped and limited by a clamping mechanism 21 such as a clamping jaw 211 through a mechanical structure. Of course, the test tube clamping device 20 can also be limited by other limiting methods such as vacuum adsorption, and the specific implementation can be set according to actual needs, which is not limited herein.

[0049] It should be noted that in the technical scheme of the present application, the clamping mechanism 21 of the test tube clamping device 20 can not only be arranged at the film tearing station to clamp the test tube to be torn. In one possible embodiment, the transfer device 50 can be provided with a plurality of test tube placing positions to place a plurality of test tubes 200 at one time, and the plurality of test tubes 200 can be sequentially transferred to the film tearing station. Correspondingly, the test tube clamping device 20 can also include a plurality of clamping mechanisms 21, each clamping mechanism 21 being arranged at a test tube placing position. In this way, the plurality of test tubes 200 on the transfer device 50 can be clamped and limited by the plurality of clamping mechanisms 21 of the test tube clamping device 20 at the same time.

[0050] In an implementation, the transfer device 50 can be provided as a carrier 51, and the carrier 51 can be provided with a first limiting hole configured to be inserted into the bottom of the test tube 200. The first limiting hole can be provided with a plurality of first limiting holes, which are sequentially and spaced apart along the circumferential direction of the avoiding hole 511. Each first limiting hole can be provided with a clamping structure, which can be but not limited to an elastic limiting member such as a retractable buckle or a spring. By providing the clamping structure, the size of the first limiting hole can be limited so that the test tube 200 can be clamped in the first limiting hole. Moreover, by configuring the clamping structure as an elastic limiting member, the carrier 51 can be limited and matched with test tubes of different diameters through the first limiting hole, thereby improving the applicability of the transfer device 50.

[0051] The film tearing device 30 includes a driving mechanism 32 and a clamping mechanism 31 for clamping 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 assembly, which can be specifically provided as a linear driving assembly. The test tube 200 is vertically placed, the clamping mechanism 31 is arranged above the test tube clamping device 20 and is in transmission connection with the linear driving assembly. In this way, the clamping mechanism 31 can be driven by the linear driving assembly to move downward 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 can be moved upward relative to the test tube 200 to drive the sealing film to separate from the test tube 200.

[0052] Specifically, the clamping mechanism 31 can move towards 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 drive the sealing film of the test tube 200 away from the test tube 200. Thus, the automatic film tearing of the test tube 200 can be realized to improve the film tearing efficiency of the test tube 200.

[0053] In other embodiments, the driving mechanism 32 of the film tearing device 30 can be provided with two or more driving assemblies. One of the driving assemblies of the driving mechanism 32 can be specifically provided as a linear driving assembly for driving the clamping mechanism 31 to move along the extension direction of the test tube 200, for moving to the opening of the test tube 200 to be in abutment with the sealing film, and for moving away from the test tube 200 along the extension direction of the test tube 200 to drive the sealing film away from the opening of the test tube 200. The remaining driving assemblies of the driving mechanism 32 can be one or more for driving the clamping mechanism 31 to move towards or away from the test tube clamping device 20. In this way, the movement flexibility of the film tearing device 30 can be improved to facilitate the movement of the sealing film to the remaining positions of the test tube film tearing apparatus 100 after the sealing film is torn off for recycling.

[0054] Please refer to Figure 3 and Figure 4 In the embodiment of the utility model, clamping mechanism 31 includes seat body assembly 313, pressure block assembly 311 and clamping assembly 312, seat body assembly 313 and drive mechanism 32 transmission connection, pressure block assembly 311 is located at seat body assembly 313, for pressing in the opening of test tube 200, to with the top surface of sealing film abut, clamping assembly 312 is liftablely arranged in seat body assembly 313, and can be set in the below of pressure block assembly 311, to have the clamping state of surrounding in the circumferential side of test tube 200 and the release state of separating from test tube 200, when clamping, clamping assembly 312 is used for moving towards pressure block assembly 311, to make clamping assembly 312 and pressure block assembly 311 cooperate and clamp sealing film.

[0055] In the embodiment, by making clamping assembly 312 liftablely arranged in seat body assembly 313, clamping assembly 312 can move towards or away from pressure block assembly 311, to realize the clamping or release of sealing film. In some embodiments, clamping assembly 312 includes lifting mechanism 3121 and jaw mechanism 3122, lifting mechanism 3121 and jaw mechanism 3122 are transmission connection, jaw mechanism 3122 can be set to open and close, to switch its clamping state and release state by the opening and closing movement of jaw mechanism 3122. Wherein, jaw mechanism 3122 can be specifically configured as pneumatic jaw, the opening and closing stroke of the pneumatic jaw can be but not limited to 180 °.

[0056] Specifically, the two clamping pieces of jaw mechanism 3122 can move towards each other to make the pneumatic jaw in the clamping state, so that the two clamping pieces can be enclosed and clamped on the circumferential side of test tube 200, to turn up the sealing film capped on test tube 200 when clamping assembly 312 moves along the extension direction of test tube 200 towards the opening end of test tube 200, and then the upper end surface of jaw mechanism 3122 of clamping assembly 312 and the lower end surface of pressure block assembly 311 can cooperate to clamp the turned-up sealing film. The two clamping pieces can also move away from each other to make the pneumatic jaw in the release state. It can be understood that by making jaw mechanism 3122 surround the circumferential side of test tube 200 in the clamping state, the whole test tube 200 is covered, which is conducive to ensuring the turning-up and clamping effect of clamping mechanism 31 on the sealing film.

[0057] Of course, the technical scheme of the utility model is not limited to this, in other embodiments, jaw mechanism 3122 in the clamping state, can also be only make two clamping pieces cover and clamp in the local position of test tube 200, to drive the whole sealing film to tear off test tube 200 by clamping cooperation with the local part of sealing film. The specific implementation can be set according to actual demand, which is not limited here.

[0058] Specifically in the embodiment, during the film tearing process of the sealing film, first, the clamping jaw mechanism 3122 of the clamping assembly 312 is kept in the released state and is kept at a certain distance from the pressing block assembly 311, at this time, the clamping mechanism 31 can be moved towards the test tube 200 as a whole under the driving of the driving mechanism 32, 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 pieces of the clamping jaw mechanism 3122 are arranged at intervals on the circumferential side of the test tube 200; then, the two clamping pieces are moved towards each other to be clamped on the circumferential side of the test tube 200, so that the clamping jaw mechanism 3122 is kept in the 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 3121 drives the clamping jaw mechanism 3122 to move towards the pressing block assembly 311, so as to drive the sealing film located between the pressing block assembly 311 and the clamping assembly 312 to be turned up towards the pressing block assembly 311, and the turned-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 jaw mechanism 3122; finally, the clamping mechanism 31 can be moved away from the test tube 200 as a whole under the driving of the driving mechanism 32, so that the pressing block assembly 311 and the clamping jaw mechanism 3122 of the clamping assembly 312 can move away from the test tube 200 synchronously while keeping the sealing film clamped, so that the sealing film can be torn off from the opening of the test tube 200, thereby realizing the automatic film tearing of the test tube 200.

[0059] Please refer to Figure 5 In the embodiment of the utility model, the pressing block assembly 311 includes a fixing piece 3111, a pressing block 3112 and an elastic piece 3113, the fixing piece 3111 is arranged on the seat body assembly 313; the pressing block 3112 is arranged at intervals below the fixing piece 3111 and is used for abutting against the top surface of the sealing film when the fixing piece 3111 moves towards the test tube 200; the elastic piece 3113 is arranged between the fixing piece 3111 and the pressing block 3112, and the two ends of the elastic piece 3113 are connected with the fixing piece 3111 and the pressing block 3112 respectively.

[0060] In the embodiment, by connecting the two ends of the elastic piece 3113 with the fixing piece 3111 and the pressing block 3112 respectively, when the fixing piece 3111 moves towards the test tube clamping device 20 along with the seat body assembly 313, the pressing block 3112 can elastically abut against the sealing film at the opening of the test tube 200, so that the lower end surface of the pressing block 3112 can be well attached to 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.

[0061] In some embodiments, a first positioning hole can be formed on one side of the fixing member 3111 facing the pressing block 3112, a second positioning hole can be formed on one side of the pressing block 3112 facing the fixing member 3111, the second positioning hole is opposite to the first positioning hole, and the two ends of the spring are limited in the first positioning hole and the second positioning hole respectively. In this way, the position stability of the spring can be improved.

[0062] Please refer to Figure 5 In the embodiment of the present application, 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 arranged in the guide hole 3111a, and the elastic member 3113 is sleeved on the guide shaft 3112a.

[0063] In this way, the cooperation stability between the fixing member 3111 and the pressing block 3112 can be improved by the guiding effect of the guide hole 3111a on the guide shaft 3112a. Further, the elastic member 3113 can be a spring, and the position stability of the spring can be further improved by the positioning effect of the guide shaft 3112a on the spring.

[0064] Specifically, in the present embodiment, the guide hole 3111a is formed on the fixing member 3111, one end of the guide shaft 3112a is connected to the pressing block 3112, the other end of the guide shaft 3112a is arranged in 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 arranged in the guide hole 3111a, and the linear bearing is arranged between the inner wall of the guide hole 3111a and the outer wall of the guide shaft 3112a, which is helpful to improve the movement stability of the guide shaft 3112a.

[0065] Please refer to Figures 3 to 5 In the embodiment of the present application, the pressing block 3112 is formed with a negative pressure channel 3112b communicating with the bottom surface of the pressing block 3112, and the pressing block assembly 311 further comprises a vacuum generator 3114, which communicates with 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.

[0066] In the present embodiment, by arranging the vacuum generator 3114 in the pressing block assembly 311, the lower end surface of the pressing block 3112 has the function of vacuum adsorption on the sealing film, thereby reducing the risk of the sealing film separating from the clamping mechanism 31 during the process of moving and clamping the sealing film.

[0067] One end of the negative pressure channel 3112b can be communicated to the bottom of the briquetting block 3112 through the adsorption hole, and the adsorption hole can be provided with one or more; the other end of the negative pressure channel 3112b is provided with a connector structure for connecting the vacuum generator 3114, so as to facilitate the installation and cooperation of the briquetting block 3112 and the vacuum generator 3114.

[0068] Please refer to Figure 2 In the embodiment of the utility model, the film tearing device 30 further includes a detection mechanism 33, which is arranged on the side of the clamping mechanism 31 and is used for moving into the upper side of the test tube clamping device 20 synchronously when the clamping mechanism 31 moves out of the upper side of the test tube clamping device 20.

[0069] Specifically in the embodiment, the detection mechanism 33 has an initial position on the side of the test tube clamping device 20 and a detection position above the test tube clamping device 20, and the clamping mechanism 31 has a clamping position above the test tube clamping device 20 and a releasing position on the side of the test tube clamping device 20. Moreover, the detection position of the detection mechanism 33 is arranged coincidentally with the clamping position of the clamping mechanism 31.

[0070] 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 moving the clamping mechanism 31 from the clamping position to the releasing position, the clamping mechanism 31 can keep 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 releasing position, the clamping mechanism 31 can release the sealing film at the test tube 200 to reset to the clamping position to perform the next film tearing step. When the detection mechanism 33 moves from the initial position to the detection position, the test tube at the test tube clamping device 20 can be detected to determine whether the sealing film exists at the test tube 200.

[0071] Moreover, the movement stroke of the detection mechanism 33 from the initial position to the detection position is the same as the movement stroke length of the clamping mechanism 31 from the clamping position to the releasing position. In this way, the sealing film at the test tube 200 can be detected whether it is torn off by moving the detection mechanism 33 into the upper side of the test tube clamping device 20 synchronously while the film tearing of the test tube 200 is completed. By making the film tearing process and the detection process simultaneously, the film tearing and detection efficiency can be improved. After the detection is completed, the clamping mechanism 31 can move into the upper side of the test tube clamping device 20 again, and the detection mechanism 33 can move out of the upper side of the test tube clamping device 20 synchronously to perform the next film tearing process and detection process.

[0072] In some embodiments, the detection mechanism 33 and the clamping mechanism 31 can be arranged to rotate synchronously under the drive of the same driving mechanism 32, and the initial position of the detection mechanism 33, the detection position of the detection mechanism 33, and the clamping position of the clamping mechanism 31 and the releasing position of the clamping mechanism 31 can be arranged equidistantly in the circumferential direction of the driving mechanism 32. Alternatively, the detection mechanism 33 and the clamping mechanism 31 can be arranged to translate synchronously under the drive of the same driving mechanism 32, and the initial position of the detection mechanism 33, the detection position of the detection mechanism 33, and the clamping position of the clamping mechanism 31 and the releasing position of the clamping mechanism 31 can be arranged equidistantly in the straight line direction. Of course, the technical scheme of the present application is not limited to this, and the detection mechanism 33 and the clamping mechanism 31 can also move synchronously under the drive of different driving mechanisms, which is not limited herein.

[0073] 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 whether the aluminum film exists at the opening of the test tube 200 can be detected by the metal sensor, and whether the sealing film at the opening of the test tube 200 is torn off can be detected. In other embodiments, the detection mechanism 33 can be set as a photographing detection mechanism 33, and the type of the detection mechanism 33 can be set according to actual needs, which is not limited herein.

[0074] Please refer to Figure 1 and Figure 2 In the embodiments of the present application, the test tube film tearing device 100 further comprises a collecting device 40, which is arranged in the machine body 10 and forms a collecting cavity with an open top.

[0075] In some embodiments, the collecting device 40 can have a funnel structure as a whole, or a funnel structure can be arranged at the opening of the collecting device 40. The cross-sectional area of the funnel structure increases gradually from bottom to top, so as to facilitate the collection and convergence of the torn sealing film. Of course, the collecting device 40 can also be arranged in other shapes such as a cylinder or a box, which is not limited herein.

[0076] Further, in an embodiment, the distance between the clamping mechanism 31 and the detection mechanism 33 is the same as the distance between the collection device 40 and the test tube clamping device 20, that is, the movement stroke of the detection mechanism 33 from the initial position beside the test tube clamping device 20 to the detection position above the test tube clamping device 20 is the same as the movement stroke of the clamping mechanism 31 from the test tube clamping device 20 to the collection device 40, so that the collection device 40 can be arranged opposite to the clamping mechanism 31 in the unloading position.

[0077] In this way, when the clamping mechanism 31 moves from the clamping position above the test tube clamping device 20 to the unloading position beside the test tube clamping device 20, it can release the sealing film so that the sealing film falls into the collection device 40, and at the same time, the detection mechanism 33 can be moved above the test tube clamping device 20, so that the clamping mechanism 31 can complete the step of moving the sealing film of the test tube 200 to the collection device 40 after tearing off the sealing film, and the detection mechanism 33 can complete the step of detecting whether the sealing film is torn off after moving above the test tube clamping device 20, so that the test tube film tearing device 100 can reduce the waste of actions during operation.

[0080] The second driving assembly 322 is used to drive the clamping assembly 312 to move into or out of the upper side of the test tube clamping device 20. In some embodiments, the second driving assembly 322 can be configured as a rotary cylinder, a rotary motor or the like rotary driving mechanism 32 to enable the first driving assembly 321 to drive the clamping mechanism 31 to rotate into or out of the upper side of the test tube clamping device 20. Of course, the embodiments of the present application are not limited to this, and in other embodiments, the second driving assembly 322 can also be configured as a telescopic cylinder, a linear module, a screw driving mechanism 32 or the like linear driving mechanism 32 to enable the first driving assembly 321 to drive the clamping mechanism 31 to move into or out of the upper side of the test tube clamping device 20 in a translational manner. The translational direction can be horizontal or inclined relative to the horizontal direction, which is not limited herein.

After the sealing film on the test tube 200 is removed, the transfer device 50 can move the test tube 200 with the film removed out of the film-removing station for subsequent detection, and the next test tube 200 to be film-removed can be simultaneously moved into the film-removing station, so that continuous and automatic film-removing of multiple test tubes 200 can be achieved.

[0086] The clamping mechanism 21 of the test tube clamping device 20 is arranged at the film-removing station and is used to limit the part of the test tube 200 other than the sealing film, so as to improve the position stability of the test tube 200 during film-removing. The clamping mechanism 21 can be a pneumatic clamping jaw. During the film-removing process of the test tube 200, the clamping mechanism 21 and the test tube 200 are limited to cooperate, so as to avoid the test tube 200 from being lifted by the film-removing device 30 and slipping or deviating. After the film-removing of the test tube 200 is completed, the clamping mechanism 21 can release the test tube 200 with the film removed, so as to clamp the next test tube 200 moved into the film-removing station.

When the two clamping jaws 211 are opened, the two clamping jaws 211 of the clamping mechanism 21 can all avoid the rotating path of the carrier 51 and the test tube 200 thereon, so as to avoid the clamping mechanism 21 from interfering with the operation of the transfer device 50, thereby without moving the clamping mechanism 21, only the opening and closing movement of the clamping mechanism 21 needs to be controlled, so that the clamping mechanism 21 can be well matched with the carrier 51 and the test tube 200 thereon.

[0089] Of course, the technical scheme of the utility model is not limited to this, in other embodiments, the clamping mechanism 21 can also be movably arranged in the film tearing station, so that the clamping mechanism 21 can move into or out of the film tearing station. When the clamping mechanism 21 moves out of the film tearing station, it can avoid the carrier 51 and the test tube 200 thereon, so as to facilitate the transfer device 50 to transfer the test tube 200 to the preset position; when the clamping mechanism 21 moves into the film tearing station, it can be aligned with the test tube 200 and complete the clamping and positioning of the test tube 200.
