[0048] See also Figure 1 The present application provides a demembrane device 1, which is used to demembrane a sample tube 2 after sealing. The demembrane device 1 can be used alone to remove the membrane and recover the membrane, or the demembrane device 1 can be used in combination with a sealing device, a storage device, and a sample analysis device to form a test line for the first test and re-test of the sample. The sample analysis device is used to perform the first test and re-test of the sample, the sealing device is used to seal the sample tube 2 after the first test, and the storage device is used to refrigerate the sealed sample tube 2 at low temperature.

[0049] As an example, the film used for sealing can be aluminum foil, copper foil or other films that can be shaped, etc., which can be specifically set according to user needs and are not limited here.

[0050] Please refer again Figure 1 , and also see Figure 2 , Figure 3 and Figure 4, wherein the film removal device 1 has a film removal station and a recycling station, and the film removal station and the recycling station are arranged at intervals along the first direction X. The film removal device 1 includes a base 90, a first translation mechanism 40, a second translation mechanism 50, a film pressing mechanism 10, a film lifting mechanism 20, a film blowing mechanism 30, a tube clamping mechanism 60 and a control mechanism. The first translation mechanism 40 is arranged on the base 90, the second translation mechanism 50 is arranged on the first translation mechanism 40, and the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are all arranged on the second translation mechanism 50. The film pressing mechanism 10 has a film pressing component 11, the film lifting mechanism 20 has a film lifting component 21, and the film blowing mechanism 30 has a film blowing component 31. The film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are controlled by the first translation mechanism 40 and the second translation mechanism 50, so that the film pressing component 11, the film lifting component 21 and the film blowing component 31 are synchronously switched between the film removal station and the recycling station. The tube clamping mechanism 60 is used to clamp the sample tube 2 to be film-removed at the film-removing station to prevent the sample tube 2 from moving. The first translation mechanism 40, the second translation mechanism 50, the film pressing mechanism 10, the film lifting mechanism 20, the film blowing mechanism 30 and the tube clamping mechanism 60 are all connected to the control mechanism, and the control mechanism is used to automatically control the first translation mechanism 40, the second translation mechanism 50, the film pressing mechanism 10, the film lifting mechanism 20, the film blowing mechanism 30 and the tube clamping mechanism 60 to realize the automatic operation of the film-removing device 1.

[0051] Specifically, the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are controlled by the first translation mechanism 40 to synchronously move linearly along the first direction X, so that the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are all aligned with the film removal station or the recycling station in the second direction Z intersecting the first direction X. The film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are controlled by the second translation mechanism 50 to synchronously move linearly along the second direction Z, so that the film pressing component 11, the film lifting component 21 and the film blowing component 31 reach the film removal station or the recycling station.

[0052] When the film pressing part 11, the film lifting part 21 and the film blowing part 31 are all located at the film removing station, the film pressing part 11 cooperates with the film lifting part 21 to remove the film, and the film blowing part 31 does not work at this time. When the film pressing part 11, the film lifting part 21 and the film blowing part 31 are all located at the recycling station, the film pressing part 11 and the film lifting part 21 release the film, and the film blowing part 31 blows the film off to realize the recycling of the film. The setting of the film blowing mechanism 30 is conducive to the film falling off, reducing the difficulty of film recycling.

[0053] For the convenience of explanation, the following embodiments are all based on Figure 1 The first direction X is a horizontal leftward direction, the direction opposite to the first direction X is a horizontal rightward direction, the second direction Z is a vertical downward direction, and the direction opposite to the second direction Z is a vertical upward direction.

[0054] The first translation mechanism 40 includes a first motor 41, a first driving wheel 42, a first driven wheel 43, a first synchronous belt 44 and a first mounting seat 45. The first motor 41 is installed on the base 90 and is transmission-connected to the first driving wheel 42. The first synchronous belt 44 is sleeved on the first driving wheel 42 and the first driven wheel 43. The first mounting seat 45 is arranged on the first synchronous belt 44. The second translation mechanism 50 is installed on the first mounting seat 45.

[0055] During actual operation, the power of the first motor 41 is synchronously transmitted to the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 by the first driving wheel 42, the first synchronous belt 44 and the first mounting seat 45 in sequence, so that the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 can be synchronously moved right or left.

[0056] By providing the first motor 41 , the first driving wheel 42 , the first driven wheel 43 , the first synchronous belt 44 and the first mounting seat 45 , the first translation mechanism 40 can stably drive the film pressing mechanism 10 , the film lifting mechanism 20 and the film blowing mechanism 30 to move.

[0057] Of course, the specific structure of the first translation mechanism 40 is not limited to the above one, and it can also be other structures, which will not be described in detail here.

[0058] The second translation mechanism 50 includes a second motor 51 and a second mounting seat 52 . The second motor 51 is mounted on the first mounting seat 45 and is in transmission connection with the second mounting seat 52 . The film pressing mechanism 10 , the film lifting mechanism 20 and the film blowing mechanism 30 are all connected to the second mounting seat 52 .

[0059] During actual operation, the power of the second motor 51 is transmitted to the film pressing mechanism 10 , the film lifting mechanism 20 and the film blowing mechanism 30 through the second mounting seat 52 , so that the film pressing mechanism 10 , the film lifting mechanism 20 and the film blowing mechanism 30 can move up or down synchronously.

[0060] By providing the second motor 51 and the second mounting seat 52 , the second translation mechanism 50 can stably drive the film pressing mechanism 10 , the film lifting mechanism 20 and the film blowing mechanism 30 to move.

[0061] Of course, the specific structure of the second translation mechanism 50 is not limited to the above one, and it can also be other structures, which will not be described in detail here.

[0062] Please refer again Figure 1 , Figure 3 and Figure 4 , and at the same time Figure 5 , Figure 6 and Figure 7The film pressing mechanism 10 further includes a film pressing movable seat 12 and a film pressing elastic member 13. The film pressing movable seat 12 is slidably connected to the second mounting seat 52, and the film pressing component 11 is abutted between the second mounting seat 52 and the film pressing movable seat 12. The film pressing component 11 is connected to the film pressing movable seat 12. The film lifting mechanism 20 further includes a film lifting driving component, which is connected to the second mounting seat 52 and is in driving connection with the film lifting component 21.

[0063] The film lifting mechanism 20 and the film pressing mechanism 10 are controlled by the second translation mechanism 50 to move synchronously along the second direction Z, so that the film pressing component 11 presses the diaphragm, and there is a height difference between the film lifting component 21 and the film pressing component 11 that is greater than the maximum thickness of the diaphragm. When there is a height difference between the film lifting component 21 and the film pressing component 11 that is greater than the maximum thickness of the diaphragm, the film lifting component 21 is controlled by the film lifting driving assembly and moves relative to the film pressing component 11, so that the projections of the film lifting component 21 and the film pressing component 11 in the second direction Z overlap.

[0064] In actual operation, the film pressing mechanism 10 and the film lifting mechanism 20 are located above the film removing station in the second direction Z, and when aligned with the film removing station, the film pressing component 11 and the film lifting component 21 are arranged side by side in the first direction X, or in a direction opposite to the first direction X, or in a third direction intersecting the first direction X and the second direction Z. For the convenience of description, the following embodiments are described by taking the arrangement of the film pressing component 11 and the film lifting component 21 along the first direction X as an example.

[0065] Specific as Figure 4 As shown, when the film pressing mechanism 10 and the film lifting mechanism 20 are located above the film removing station and aligned with the film removing station, the second translation mechanism 50 drives the film lifting mechanism 20 and the film pressing mechanism 10 to move downward synchronously, so that the film pressing component 11 and the film lifting component 21 can both move to the film removing station, and the film pressing component 11 abuts against the diaphragm sealing the tube mouth of the sample tube 2.

[0066] Specific as Figure 5 As shown, the second translation mechanism 50 then continues to drive the film lifting mechanism 20 and the film pressing mechanism 10 to move downwards. Due to the obstruction of the sample tube 2, the film pressing movable seat 12 and the film pressing component 11 no longer move, and the film pressing elastic member 13 contracts. At the same time, the film lifting component 21 continues to move downwards until the film lifting component 21 is located below the film pressing component 11 and there is a height difference between the film lifting component 21 and the film pressing component 11 that is greater than the maximum thickness of the film.

[0067] Specific as Figure 6 As shown, after that, the film-lifting driving assembly drives the film-lifting component 21 to move rightward relative to the film-pressing component 11, so that the projections of the film-lifting component 21 and the film-pressing component 11 in the second direction Z overlap.

[0068] Specific as Figure 7As shown, the second translation mechanism 50 then drives the second mounting seat 52 to move upward. At this time, due to the presence of the film pressing elastic member 13, the film pressing component 11 remains stationary relative to the sample tube 2, but the film lifting component 21 moves upward under the drive of the second translation mechanism 50 until it cooperates with the film pressing component 11 and clamps the film.

[0069] Then, under the action of the second translation mechanism 50, the film lifting component 21 and the film pressing component 11 clamp the film and drive the film to move upward and exit from the film removing station to complete the film removal.

[0070] It is worth mentioning that the diaphragm may be a structure with a flat surface and uniform thickness, or the same diaphragm may have areas with inconsistent thickness. Therefore, when there is a height difference between the film-lifting component 21 and the film-pressing component 11 that is greater than the maximum thickness of the diaphragm, it can be ensured that the film-pressing component 11 and the film-lifting component 21 can be distributed on the top and bottom sides of the diaphragm and clamp the diaphragm.

[0071] In the present application, the film removal station refers to a station with a certain area range. The area range from when the film pressing part 11 contacts the diaphragm to when the film pressing part 11 presses the diaphragm, the area range from when the film lifting part 21 contacts the diaphragm to when the film lifting part 21 moves downward relative to the film pressing part 11 to a height difference greater than the maximum thickness of the diaphragm, the area range from when the film lifting part 21 moves right relative to the film pressing part 11, and the area range from when the film lifting part 21 moves upward relative to the film pressing part 11 to abut against the diaphragm and clamp the diaphragm together with the film pressing mechanism 10 all belong to the area range of the film removal station.

[0072] By providing the film pressing elastic member 13 and the film lifting driving assembly, the two cooperate to realize the relative movement between the film lifting component 21 and the film pressing component 11, so as to facilitate film removal.

[0073] Please refer again Figure 1 , Figure 2 and Figure 3 In some embodiments, the lamination mechanism 10 further includes a lamination guide shaft 14, which is disposed on the second mounting seat 52, and the lamination elastic member 13 is sleeved outside the lamination guide shaft 14. The lamination guide shaft 14 is used to position and guide the lamination elastic member 13.

[0074] In some embodiments, the film lifting drive assembly includes a film lifting motor 22, a film lifting rail 23 and a film lifting slider 24. The film lifting motor 22 and the film lifting rail 23 are both mounted on the second mounting seat 52, and the film lifting motor 22 is in transmission connection with the film lifting slider 24. The film lifting slider 24 is slidably mounted on the film lifting rail 23. The film lifting component 21 is mounted on the film lifting slider 24. The film lifting motor 22 is used to drive the film lifting slider 24 to drive the film lifting component 21 to move right or left. The arrangement of the film lifting motor 22, the film lifting rail 23 and the film lifting slider 24 is conducive to improving the stability of the film lifting component 21 moving right or left relative to the film pressing component 11.

[0075] In some embodiments, the film removal device 1 also includes a film removal detection component 80, which is arranged on the second mounting seat 52 and is used to detect whether the film lifting component 21 and the film pressing component 11 cooperate to complete the film removal. After completing the film removal, the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 are controlled by the first translation mechanism 40 to move linearly along the first direction X.

[0076] Specifically, the film removal detection member 80 and the film pressing member 11 are arranged at intervals along the first direction X, and the film removal detection member 80 is electrically connected to the control mechanism. After the film pressing member 11 and the film lifting member 21 cooperate and complete the film removal, the first translation mechanism 40 drives the film pressing mechanism 10, the film lifting mechanism 20 and the film removal detection member 80 to move leftward along the first direction X, so that the film removal detection member 80 can be aligned with the sample tube 2 of the film removal station in the second direction Z.

[0077] Next, the second translation mechanism 50 drives the film removal detection member 80 to move downward along the second direction Z, so that the film removal detection member 80 can be located above the sample tube 2 and close to the tube mouth of the sample tube 2 for detection. The film removal detection member 80 feeds back the detection information to the control mechanism. The control mechanism determines whether the film at the tube mouth of the sample tube 2 is removed based on the feedback information. If the film is removed, the control mechanism controls the first translation mechanism 40 to drive the film pressing mechanism 10, the film lifting mechanism 20 and the film blowing mechanism 30 to move left along the first direction X to a position aligned with the recovery station in the second direction Z.

[0078] Generally, the diaphragm is made of metal material, so the film removal detection part 80 can be a detection part for sensing metal. Alternatively, the film removal detection part 80 can also be a distance measurement detection part. When the diaphragm is not removed, the film removal detection light beam emitted by the film removal detection part 80 can be immediately reflected by the diaphragm. When the diaphragm is removed, the film removal detection light beam emitted by the film removal detection part 80 will pass through the sample tube 2. The film removal detection part 80 can receive less film removal detection light beams and it takes a long time to receive the film removal detection light beams. Therefore, the control mechanism can determine whether the film is removed according to the time and light intensity of the received film removal detection light beam.

[0079] By providing the film removal detection member 80, the film removal device 1 can automatically determine whether to remove the film, thereby reducing manual intervention and improving work efficiency.

[0080] Please refer again Figure 1 and Figure 2 , and also see Figure 8 In some embodiments of the present application, the film removal device 1 further includes a recycling mechanism 70, which includes a recycling component 71, which is located at the recycling station and has an open cavity 73 for collecting the blown-off film to prevent the film from scattering and causing environmental pollution. The recycling component 71 is provided with an avoidance notch 72, which is located at the top of the recycling component 71 and is connected to the open cavity 73. The film removal detection member 80, the film pressing component 11 and the recycling component 71 are arranged along the first direction X.

[0081] The film removal detection member 80, the film pressing member 11 and the recovery member 71 are arranged along the first direction X. In actual operation, when the film pressing member 11 and the film lifting member 21 cooperate to complete film removal, the first translation mechanism 40 drives the film pressing member 11, the film lifting member 21 and the film removal detection member 80 to move along the first direction X. The film pressing member 11 and the film lifting member 21 gradually move leftward in the first direction X and approach the recovery member 71, and the film removal detection member 80 can move to a position aligned with the film removal station for detection. After the detection is completed, the first translation mechanism 40 drives the film pressing member 11 and the film lifting member 21 to continue to move leftward along the first direction X, and the film pressing member 11 and the film lifting member 21 can reach the top of the recovery member 71. It can be seen that this arrangement method can not only perform film removal detection, but also facilitate the rapid switching between the film pressing member 11 and the film lifting member 21 between the film removal station and the recovery station, thereby improving work efficiency.

[0082] Then, under the action of the second translation mechanism 50, the film pressing component 11, the film lifting component 21 and the film blowing component 31 move down to the recovery station along the second direction Z, and the film pressing component 11 abuts against the opening of the open cavity 73. Then, the second translation mechanism 50 continues to drive the film lifting component 21 to continue to move down in the avoidance notch 72 until the film lifting component 21 is located below the film pressing component 11. At this time, the film lifting component 21 and the film pressing component 11 are spaced apart in the second direction Z and can be loosened. Due to the obstruction of the recovery component 71, during this process, the film pressing component 11 and the film blowing component 31 no longer move, and the film pressing elastic member 13 contracts. Then, the film blowing component 31 blows the film sheet into the open cavity 73 for recovery.

[0083] After the film lifting component 21 and the film pressing component 11 loosen the film and the film falls off, the film lifting component 21, the film pressing component 11 and the film blowing component 31 move upward under the action of the second translation mechanism 50 to avoid the recovery component 71, and then move right under the action of the first translation mechanism 40 until the film lifting component 21, the film pressing component 11 and the film blowing component 31 are aligned with the film removal station in the second direction Z.

[0084] It can be seen that by designing the film removal detection component 80, the film pressing component 11 and the recovery component 71 to be arranged along the first direction X, it is beneficial for the film lifting component 21 and the film pressing component 11 to quickly and synchronously realize the station switching between the film removal station and the recovery station, and in the process of switching from the film removal station to the recovery station, film removal detection can also be performed, and the work efficiency is high.

[0085] It is worth mentioning that in the present application, the recovery station refers to a station with a certain area range. The area range that the film pressing component 11 passes through from the contact between the film pressing component 11 and the opening of the open cavity 73 to the film pressing component 11 pressing the opening of the open cavity 73, and the area range that the film lifting component 21 passes through from the contact between the film pressing component 11 and the opening of the open cavity 73 to the downward movement of the film lifting component 21 relative to the film pressing component 11 to the release of the film from the film pressing component 11, all belong to the area range of the recovery station.

[0086] In some embodiments, the recovery mechanism 70 also includes a recovery detection component, which is arranged in the open cavity 73 and electrically connected to the control mechanism. The recovery detection component is used to detect whether the diaphragm falls into the open cavity 73. The control mechanism is used to send an error signal when the recovery detection component fails to detect the diaphragm falling into the open cavity 73 for a preset number of consecutive times.

[0087] Specifically, the recovery detection member is used to emit and receive a recovery detection beam. When the film falls into the open cavity 73, the detection beam is blocked by the film, so that the recovery detection member cannot receive the recovery detection beam for a short period of time. In this way, the control mechanism can determine that the film has fallen and is recovered. When the recovery detection member detects the film falling for a preset number of consecutive times, the control mechanism sends an error signal to prompt the operator to check the fault in time.

[0088] The accumulated preset number of times can be 1 time, 2 times, 3 times, etc., which can be set as needed. Taking 3 times as an example, the film lifting component 21 and the film pressing component 11 move to the recovery station 3 times to loosen the film. When the recovery detection component fails to detect the film falling for 3 consecutive times, it means that the film removal device 1 is faulty. Therefore, the control mechanism sends an error signal to prompt the operator to check the fault.

[0089] It can be seen that by setting up a recovery detection component, faults can be reported in a timely manner to facilitate troubleshooting.

[0090] Please also read Figure 4 and Figure 5 In some embodiments, the film pressing component 11 has a avoidance hole set through along the second direction Z, and the aperture of the avoidance hole is smaller than the diameter of the sample tube 2. The film blowing component 31 is arranged on the film pressing component 11 and is coaxially arranged with the avoidance hole.

[0091] The central axis of the film blowing component 31 coincides with the central axis of the avoidance hole, and the film blowing component 31 can penetrate the avoidance hole along the second direction Z, and the air outlet of the film blowing component 31 is flush with the bottom surface of the film pressing component 31, or can extend into the avoidance hole but not penetrate the avoidance hole, or can be located on the top surface of the film pressing component 11 and aligned with the avoidance hole and fluidly connected. Under this design, the airflow blown by the film blowing component 31 can effectively blow off the film.

[0092] In some embodiments, the film blowing mechanism 30 further includes a film blowing pump, which is in fluid communication with the film blowing component 31 and is used to drive external airflow to blow out through the film blowing component 31. The film blowing pump is used to provide power for airflow to blow out through the film blowing component 31.

[0093] See also Fig. 9 In some embodiments, the tube clamping mechanism 60 includes a base 61, a tube clamping drive assembly and a tube clamping assembly. The tube clamping drive assembly is disposed on the base 61 and is in transmission connection with the tube clamping assembly. The tube clamping drive assembly is used to drive the tube clamping assembly to open or close. When the tube clamping assembly is opened, the tube clamping assembly releases the sample tube 2 to facilitate the transfer of the sample tube 2 after film removal to the sample analysis device for re-inspection. When the tube clamping assembly is closed, the tube clamping assembly clamps the sample tube 2 so that the sample tube 2 can be fixed at the film removal station for film removal.

[0094] Among them, the tube clamping driving assembly includes a tube clamping motor 62, a tube clamping driving wheel 63, a tube clamping driven wheel 64 and a tube clamping synchronous belt 65. The tube clamping motor 62 is arranged on the base 61 and is connected to the tube clamping driving wheel 63. The tube clamping synchronous belt 65 is sleeved outside the tube clamping driving wheel 63 and the tube clamping driven wheel 64.

[0095] In some embodiments, the tube clamping assembly includes a first tube clamping seat 66 and a second tube clamping seat 67, a first clamping block 68 and a second clamping block 69, and a first tube clamping elastic member and a second tube clamping elastic member. The first tube clamping seat 66 and the second tube clamping seat 67 are both arranged on the tube clamping synchronous belt 65, the first clamping block 68 is arranged on the first tube clamping seat 66, and the first tube clamping elastic member abuts between the first tube clamping seat 66 and the first clamping block 68, the second clamping block 69 is arranged on the second tube clamping seat 67, and the second tube clamping elastic member abuts between the second tube clamping seat 67 and the second clamping block 69.

[0096] In actual operation, the power of the tube clamping motor 62 is sequentially transmitted to the first tube clamping seat 66 and the second tube clamping seat 67 through the tube clamping driving wheel 63 and the tube clamping synchronous belt 65, so that the first clamping block 68 and the second clamping block 69 can be opened to release the sample tube 2, or the first clamping block 68 and the second clamping block 69 can be closed to clamp the sample tube 2. The provision of the first tube clamping elastic member and the second tube clamping elastic member is conducive to reducing the collision force between the first clamping block 68 and the second clamping block 69 and the sample tube 2, thereby reducing the risk of damage to the sample tube 2 during the clamping process.

[0097] When the film pressing part 11, the film lifting part 21 and the film blowing part 31 of the film removing device 1 are all located at the recovery station, the film pressing part 11 and the film lifting part 21 release the film, and the film blowing part 31 blows the film off to realize the recovery of the film. The setting of the film blowing mechanism 30 is conducive to the film falling off, reducing the difficulty of film recovery.
