[0043] Please also read Figure 1 , Figure 2 and Figure 3 The present application provides a film sealing device, which is used to seal the sample tube 2 after the first test. The film sealing device can be used alone, or the film sealing device can be used in combination with a film removal 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 storage device is used to refrigerate the sample tube after the film is sealed, and the film removal device is used to remove the film and recover the film before re-testing.

[0044] As an example, the diaphragm may be aluminum foil, copper foil or other diaphragms that can be shaped, etc., and may be specifically configured according to user needs and is not limited here.

[0045] The film sealing device comprises a film cutting device and a film sealing device 1. The film cutting device is used to transfer and cut the film. The film sealing device 1 is used to transfer the short strips of film formed by cutting and cover the tube mouth of the sample tube, and heat-seal and shape the film.

[0046] The film sealing device 1 has a film sealing station and a film taking station arranged along a first direction X. The film sealing device 1 includes a base 70, a first translation mechanism 40, a film taking mechanism 10, a film sealing mechanism 20, a shaping mechanism 30 and a tube clamping mechanism 60. The tube clamping mechanism 60 is used to clamp and fix the sample tube 2 at the film sealing station. The first translation mechanism 40 is arranged on the base 70 and is transmission-connected with the film taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30. The film taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30 move linearly synchronously along the first direction X under the drive of the first translation mechanism 40 until the film taking mechanism 10 is aligned with the film taking station in a second direction Z intersecting with the first direction X, and the shaping mechanism 30 is aligned with the film sealing station in the second direction Z. The film taking mechanism 10 and the shaping mechanism 30 are driven by the first translation mechanism 40 to move linearly in a direction opposite to the first direction X synchronously until the film taking mechanism 10 and the film sealing mechanism 20 are aligned with the film sealing station in the second direction Z.

[0047] For the convenience of explanation, the following embodiments are all based on Figure 1The first direction X is the right direction, the direction opposite to the first direction X is the left direction, and the second direction Z is the vertical downward direction for illustration.

[0048] The film taking mechanism 10 has a film taking component 18, and the shaping mechanism 30 has a shaping component 34. After the film taking mechanism 10 is aligned with the film taking station, and the shaping mechanism 30 is aligned with the film sealing station, the film taking component 18 moves down along the second direction Z to the film taking station to take the film. At the same time, the shaping component 34 moves down along the second direction Z to the film sealing station to shape the sample tube 2 after the film is sealed, so that the part of the film sheet that exceeds the sample tube 2 is attached to the tube wall of the sample tube 2, reducing the space occupied by a single sealed sample tube 2. In this way, the film sealing device 1 can take the film and shape at the same time, and has high working efficiency.

[0049] After the film taking mechanism 10 is aligned with the film sealing station, the film taking component 18 moves down along the second direction Z to the film sealing station, and the film taking mechanism 10 places and fixes the film sheet on the tube mouth of the sample tube 2. At this time, the shaping mechanism 30 is offset from the film taking station and the film sealing station, so the shaping mechanism 30 does not work.

[0050] Furthermore, the film sealing mechanism 20 is coaxially arranged with the film taking mechanism 10, and the film sealing mechanism 20 has a film sealing component 23, and the film sealing component 23 is spaced outside the film taking component 18. Driven by the first translation mechanism 40, the film sealing mechanism 20 is synchronously aligned with the film taking mechanism 10 at the film taking station or the film sealing station.

[0051] After the film sealing mechanism 20 and the film taking mechanism 10 are aligned with the film taking position, the film sealing mechanism 20 does not work, and the film taking component 18 takes the film. When the film sealing mechanism 20 and the film taking mechanism 10 are aligned with the film sealing position, the film taking component 18 places and fixes the film at the tube mouth of the sample tube 2. At the same time, the film sealing component 23 of the film sealing mechanism 20 heat-seals the film.

[0052] Under this design, the film taking mechanism 10 and the film sealing mechanism 20 perform station switching synchronously, which reduces the frequency of station switching and improves work efficiency. Moreover, when the film taking component 18 and the film sealing component 23 work synchronously at the film sealing station, since the film taking component 18 can fix the film, it is helpful to reduce the risk of the film moving during the heat sealing process, and the heat sealing effect is better. In addition, the film sealing mechanism 20 is coaxially arranged with the film taking mechanism 10, and the film sealing mechanism 20 has a film sealing component 23, and the film sealing component 23 is spaced outside the film taking component 18, which also helps to improve the compactness of the film sealing device 1 structure and achieve the purpose of reducing the occupied space of the film sealing device 1.

[0053] The first translation mechanism 40 is used to drive the film taking mechanism 10 and the shaping mechanism 30 to translate in the first direction X or in a direction opposite to the first direction X, so as to synchronously switch the working positions of the film taking mechanism 10 and the shaping mechanism.

[0054] Please refer again Figure 3 In some embodiments, 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 70 and is connected to the first driving wheel 42. The first driving wheel 42 and the first driven wheel 43 are arranged at intervals along the first direction X. The first synchronous belt 44 is sleeved on the outside of the first driving wheel 42 and the first driven wheel 43. The first mounting seat 45 is fixed on the first synchronous belt 44. The film taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30 are all connected to the first mounting seat 45.

[0055] During actual operation, the power of the first motor 41 is synchronously transmitted to the film taking mechanism 10, the film sealing mechanism 20 and the shaping 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 taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30 can move synchronously along the first direction X and the direction opposite to the first direction X.

[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 taking mechanism 10 , the film sealing mechanism 20 and the shaping 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] Please also read Figure 2 and Figure 3 In some embodiments, the film taking mechanism 10 further includes a film taking driving assembly, which is transmission-connected to the film taking part 18 and is used to drive the film taking part 18 to move relative to the film sealing part 23 along the second direction Z when the film taking mechanism 10 and the film sealing mechanism 20 are both aligned with the film taking position, so that the film taking part 18 at least partially extends out of the film sealing part 23 until the film taking part 18 moves to the film taking position; the film sealing device 1 further includes a second translation mechanism 50, which is arranged on the first translation mechanism 40, and the film sealing mechanism 20 and the film taking mechanism 10 are both arranged on the second translation mechanism 50; the second translation mechanism 50 is used to drive the film taking mechanism 10 and the film sealing mechanism 20 to synchronously move linearly along the second direction Z when the film taking mechanism 10 and the film sealing mechanism 20 are both aligned with the film sealing position, until the film taking part 18 and the film sealing part 23 are both moved to the film sealing position.

[0059] Among them, the film taking part 18 is a vacuum suction head, and the film taking mechanism 10 also includes a vacuum pumping component, which includes a vacuum pump and a pressure detection component. The vacuum pump is installed on the base 70 and is used to extract the air in the film taking part 18. The pressure detection component is used to detect the actual vacuum degree in the film taking part 18, and feed back the detected actual vacuum degree to the control device of the film sealing equipment. When the actual vacuum degree is less than the preset vacuum degree, the control device controls the vacuum pump to increase the output power to improve the vacuum degree in the film taking part 18, so that the film can be adsorbed more firmly.

[0060] The film sealing component 23 is a component with an electric heating function. It is hollow and has an escape cavity penetrating the component along the second direction Z. The film removing component 18 can move up and down relative to the film sealing component 23 in the escape cavity.

[0061] During actual operation, the first translation mechanism 40 synchronously drives the film taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30 to synchronously move rightward along the first direction X, so that the film taking mechanism 10 and the film sealing mechanism 20 are aligned with the film taking station, and the shaping mechanism 30 is aligned with the film sealing station. Next, the film taking drive assembly drives the film taking part 18 to move downward along the second direction Z relative to the film sealing part 23, and the film taking part 18 at least partially extends out of the film sealing part 23 and reaches down to the film taking station to take the film. Then, the film taking drive assembly drives the film taking part 18 to drive the film sheet to move upward in the direction opposite to the second direction Z and exit the film taking station, but after the movement is completed, the film taking part 18 still partially extends out of the film sealing part 23 in the second direction Z, and the film sheet is also located outside the film sealing part 23. Since the film sealing component 23 has been activated during the film removal process, the film removal component 18 is set to at least partially extend out of the film sealing component 23 when the film removal component 18 is removing the film in order to avoid the film being heat-sealed at the film removal station, so as to prevent the film from being wasted or the components carrying the film at the film removal station from being damaged. Similarly, after the film removal component 18 has finished moving upward relative to the film sealing component 23, the film removal component 18 is set to still protrude out of the film sealing component 23 in the second direction Z in order to reduce the risk of the film being damaged by contact with the film sealing component 23.

[0062] In the process of the film taking component 18 moving down and taking the film, the shaping component 34 of the shaping mechanism 30 moves down to the film sealing station synchronously to complete the shaping. When the film taking component 18 moves up relative to the film sealing component 23, the shaping component 34 moves up synchronously.

[0063] Next, the first translation mechanism 40 synchronously drives the film taking mechanism 10, the film sealing mechanism 20 and the shaping mechanism 30 to move leftward in the direction opposite to the first direction X, so that the film taking mechanism 10 and the film sealing mechanism 20 are aligned with the film sealing station. Then, the second translation mechanism 50 synchronously drives the film taking mechanism 10 and the film sealing mechanism 20 to move downward in the second direction Z, so that both the film taking component 18 and the film sealing component 23 can be lowered to the film sealing station. After that, the film taking component 18 places and fixes the film sheet on the tube mouth of the sample tube 2. At the same time, the film sealing component 23 works and heat-seals the film sheet on the sample tube 2. After the heat sealing is completed, the film taking mechanism 10 and the film sealing mechanism 20 move upward in the direction opposite to the second direction Z under the action of the second translation mechanism 50, so that the film taking component 18 and the film sealing component 23 can withdraw from the film sealing station to prepare for the subsequent film taking.

[0064] By setting up the film taking drive assembly and the second translation mechanism 50, in conjunction with the first translation mechanism 40, the film taking component 18 can be freely switched between the film taking station and the film sealing station, and can cooperate with the film sealing component 23 to complete the sealing of the sample tube 2 at the film sealing station, thereby achieving high working efficiency.

[0065] The film taking driving assembly includes a film taking motor 11, a film taking transmission member 12, a film taking movable seat 13 and a film taking elastic member 14. The film taking motor 11, the film taking transmission member 12, the film taking movable seat 13 and the film taking member 18 are arranged along the second direction Z. One end of the film taking transmission member 12 is transmission-connected to the film taking motor 11, and the other end of the film taking transmission member 12 away from the film taking motor 11 is sleeved in the film taking movable seat 13. The film taking elastic member 14 abuts between the film taking transmission member 12 and the film taking movable seat 13, and the film taking member 18 is connected to the film taking movable seat 13.

[0066] The film taking motor 11 is used to drive the film taking transmission member 12 to move and compress the film taking elastic member 14 when the film taking mechanism 10 is aligned with the film taking station, so that the film taking elastic member 14 pushes the film taking component 18 to move along the second direction Z until the film taking component 18 moves to the film taking station.

[0067] The film taking motor 11 is also used to drive the shaping transmission member 32 to pull the film taking component 18 upward and exit the film taking station when the film taking mechanism 10 completes film taking. That is to say, during the process of the film taking component 18 moving upward relative to the film sealing component 23, the power comes from the film taking motor, and at this time, the elastic force of the film taking elastic member 14 does not act on the upward movement of the film taking component 18.

[0068] Under the action of the film-taking elastic member 14, the film-taking component 18 can be closely attached to the film sheet of the film-taking station, thereby ensuring the airtightness of the film-taking component 18 and achieving a good adsorption effect.

[0069] It is worth mentioning that, after the film taking is completed and the film taking component 18 exits the film taking station, the film taking component 18 still partially protrudes out of the film sealing component 23. Therefore, when sealing the film, the film taking component 18 transfers the film to the tube mouth of the sample tube 2 before the film sealing component 23. Afterwards, the film taking component 18 abuts the film against the tube mouth of the sample tube 2. When the second translation mechanism 50 continues to drive the film taking mechanism 10 and the film sealing mechanism 20 to move downward along the second direction Z, the film taking component 18 is fixed, and the film taking elastic member 14 absorbs the distance that the film needs to continue to move by compression. At the same time, the film sealing component 23 moves down to a position flush with the film taking component 18 and completes heat sealing, and has a good heat sealing effect. It can be seen that the setting of the film taking elastic member 14 can also reduce the rigid impact between the film taking component 18 and the sample tube 2 during the movement of the film taking component 18 and the film sealing component 23 to the film sealing station, thereby ensuring the film taking and film sealing effects, thereby achieving the purpose of improving the reliability of the film sealing device 1.

[0070] Further, in some embodiments of the present application, the film taking drive assembly further includes a first film taking mounting plate 15, a second film taking mounting plate 16 and a film taking guide column 17, the first film taking mounting plate 15 and the second film taking mounting plate 16 are spaced apart on opposite sides of the film taking movable seat 13 along the second direction Z, the film taking guide column 17 penetrates the film taking movable seat 13 and is connected between the first film taking mounting plate 15 and the second film taking mounting plate 16, and the film taking guide column 17 is configured to guide the movement of the film taking movable seat 13. This design is conducive to improving the stability of the movement of the film taking movable seat 13 and the film taking component 18.

[0071] Furthermore, in some embodiments of the present application, the film taking drive assembly further includes a film taking guide bearing, which passes through the film taking moving seat 13 and is sleeved outside the film taking guide column 17. The film taking guide bearing is a linear bearing, and the setting of the film taking guide bearing can reduce the friction when the film taking moving seat moves, and the movement is more stable.

[0072] In some embodiments, the film taking drive assembly also includes a film taking support column and a film taking support seat 19. The film taking support seat 19 is arranged below the film taking movable seat 13 along the second direction Z. The film taking support column is connected between the film taking movable seat 13 and the film taking support seat 19. The film taking component 18 passes through and is fixed on the film taking support seat 19.

[0073] In some embodiments, the film sealing component 23 also includes a film sealing elastic member, a film sealing guide shaft 21 and a film sealing bushing 22. The film sealing bushing 22 is installed on the second film removal mounting plate 16. One end of the film sealing guide shaft 21 is sleeved in the film sealing bushing 22, and the other end is connected to the film sealing component 23. The film sealing elastic member shrinks and abuts between the film sealing guide shaft 21 and the film sealing bushing 22. In the process of the film sealing component 23 moving to the film sealing station and abutting against the film, the setting of the film sealing elastic member can reduce the impact of the film sealing component 23 on the film and the sample tube 2, thereby ensuring the reliability of heat sealing. In addition, the setting of the film sealing elastic member, through the buffering function of the film sealing elastic member, can also reduce the difference in installation height between different sample tubes 2 of the same specification at the film sealing station, and the situation where the heat sealing depth is too deep or too shallow due to the difference in production errors between different sample tubes of the same specification, and has high adaptability to achieve a good heat sealing effect.

[0074] The second translation mechanism 50 includes a second mounting seat 51, a second motor 52, a second driving wheel 53, a second driven wheel 54, a second synchronous belt 55 and a sliding seat 56. The second mounting seat 51 is assembled on the first mounting seat 45. The second motor 52 is mounted on the second mounting seat 51 and is transmission-connected with the second driving wheel 53. The second driving wheel 53 and the second driven wheel 54 are arranged at intervals along the second direction Z. The second synchronous belt 55 is sleeved on the second driving wheel 53 and the second driven wheel 54. The sliding seat 56 is slidably mounted on the second mounting seat 51. The film taking mechanism 10 and the film sealing mechanism 20 are both mounted on the second mounting seat 51.

[0075] During actual operation, the power of the second motor 52 is transmitted to the film taking mechanism 10 and the film sealing mechanism 20 in sequence through the second driving wheel 53, the second synchronous belt 55 and the sliding seat 56 to drive the film taking mechanism 10 and the film sealing mechanism 20 to move synchronously along the second direction Z or in a direction opposite to the second direction Z.

[0076] By providing the second motor 52 , the second driving wheel 53 , the second driven wheel 54 , the second synchronous belt 55 , the second mounting seat 51 and the sliding seat 56 , the second translation mechanism 50 can stably drive the film taking mechanism 10 and the film sealing mechanism 20 to move.

[0077] Furthermore, in some embodiments of the present application, the second translation mechanism 50 further includes a slide rail 57, the slide rail 57 extends along the second direction Z, and the sliding seat 56 is slidably disposed on the slide rail 57. The slide rail 57 is used to guide the sliding seat 56, the film taking mechanism 10 and the film sealing mechanism 20 to move synchronously, which is beneficial to improving the sliding stability of the film taking mechanism 10 and the film sealing mechanism 20.

[0078] It is worth mentioning that the first film taking installation plate 15 and the second film taking installation plate 16 of the film taking mechanism 10 are both installed on the sliding seat 56 .

[0079] Please also read Figure 4 and Figure 5 In some embodiments of the present application, the shaping mechanism 30 includes a shaping motor 31, a shaping transmission member 32, a shaping movable seat 33, a shaping component 34 and a shaping elastic member 35. The shaping motor 31, the shaping transmission member 32, the shaping movable seat 33 and the shaping component 34 are arranged along the second direction Z. One end of the shaping transmission member 32 is connected to the shaping motor 31 for transmission, and the other end of the shaping transmission member 32 away from the shaping motor 31 is sleeved in the shaping movable seat 33. The shaping elastic member 35 abuts between the shaping transmission member 32 and the shaping movable seat 33, and the shaping component 34 is connected to the shaping movable seat 33. The shaping motor 31 is used to drive the shaping transmission member 32 to move along the second direction Z and compress the shaping elastic member 35 when the shaping mechanism 30 is aligned with the film sealing station, so that the shaping elastic member 35 pushes the shaping component 34 to move along the second direction Z until the shaping component 34 reaches the film sealing station.

[0080] The shaping motor 31 is used to drive the shaping transmission member 32 to move and compress the shaping elastic member 35 when the shaping mechanism 30 is aligned with the film sealing station, so that the shaping elastic member 35 pushes the shaping component 34 to move along the second direction Z until the shaping component 34 moves to the film sealing station. Under the action of the shaping elastic member 35, the rigid impact between the shaping component 34 and the sample tube 2 and the diaphragm located at the film sealing station can be avoided, thereby ensuring the integrity of the sample tube 2 during the shaping process.

[0081] The shaping member 34 has a shaping channel 341. After the shaping member 34 moves to the film sealing station, as the shaping member 34 moves further downward, the wall surface of the shaping channel 341 squeezes the membrane so that the portion of the membrane that exceeds the sample tube 2 is attached to the tube wall of the sample tube 2. Specifically, the shaping channel 341 has different inner diameters at different positions in the second direction Z (e.g., Figure 5 D in the figure), and in the second direction Z, a section with a larger inner diameter in the shaping channel 341 is located below a section with a smaller inner diameter. Different inner diameters are matched with sample tubes 2 of different diameters, and have a wide range of applicability. Furthermore, the inner diameter of the shaping channel 341 gradually increases along the second direction Z. Therefore, when the shaping component 34 moves downward, the sample tube 2 gradually adheres to the wall of the shaping channel 341, and the plastic sealing effect is good. The shaping motor 31 is also used to drive the shaping transmission member 32 to pull the shaping component 34 to move up and exit the film sealing station when the shaping mechanism 30 completes the shaping. In other words, in the process of the shaping component 34 moving upward, the power comes from the shaping motor 31. At this time, the elastic force of the shaping elastic member 35 has no effect on the upward movement of the shaping component 34.

[0082] Further, in some embodiments of the present application, the shaping mechanism 30 further includes a first shaping mounting plate 36, a second shaping mounting plate 37 and a shaping guide column 38, the first shaping mounting plate 36 and the second shaping mounting plate 37 are mounted on the first mounting seat 45, and are spaced apart on opposite sides of the shaping movable seat 33 along the second direction Z, the shaping guide column 38 passes through the shaping movable seat 33 and is connected between the first shaping mounting plate 36 and the second shaping mounting plate 37, and the shaping guide column 38 is configured to guide the movement of the shaping movable seat 33. This design is conducive to improving the stability of the movement of the shaping movable seat 33 and the shaping component 34.

[0083] Furthermore, in some embodiments of the present application, the shaping mechanism 30 further includes a shaping guide bearing, which passes through the shaping movable seat 33 and is sleeved outside the shaping guide column 38. The shaping guide bearing is a linear bearing, and the setting of the shaping guide bearing can reduce the friction when the shaping movable seat 33 moves, and the movement is more stable.

[0084] In some embodiments of the present application, the shaping mechanism 30 also includes a shaping support column 39 , which is arranged below the shaping movable seat 33 along the second direction Z, and the shaping support column 39 is connected between the shaping movable seat 33 and the shaping component 34 .

[0085] See also Figure 6 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 arranged on the base 61 and is transmission-connected to 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 shaped sample tube 2. 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 in the film sealing station for film sealing and shaping.

[0086] 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.

[0087] 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 71 and a second tube clamping elastic member 72. The first tube clamping seat 66 and the second tube clamping seat 67 are both arranged on the synchronous belt, the first clamping block 68 is arranged on the first tube clamping seat 66, and the first tube clamping elastic member 71 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 72 abuts between the second tube clamping seat 67 and the second clamping block 69.

[0088] 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 71 and the second tube clamping elastic member 72 is conducive to weakening the clamping 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.

[0089] See also Figure 1 , Figure 2 and Figure 3 , after the shaping mechanism 30 of the above-mentioned film sealing device 1 is aligned with the film sealing station, the film taking component 18 of the film taking mechanism 10 moves down along the second direction Z to the film taking station to take the film, and at the same time, the shaping component 34 of the shaping mechanism 30 moves down along the second direction Z to the film sealing station to shape the sample tube 2 after the film is sealed. In this way, the film sealing device 1 can take the film and shape it at the same time, and has a higher working efficiency.
