[0048] Specific combination Figures 1 to 10As shown, the film sealing instrument is used to complete the sealing of multi-well plates, PCR plates, deep-well plates and microplates, etc. In this embodiment, the film sealing of multi-well plates is taken as an example. Specifically, the film sealing instrument includes a frame 100, a film sealing device, a carrier assembly 300 and a door assembly 400. A film sealing cavity with an opening is provided inside the frame 100, and the opening of the film sealing cavity is connected to the side wall of the frame 100; the film sealing device includes a first power mechanism 210 and a film sealing mechanism 220, the first power mechanism 210 is provided on the top plate 110 of the frame 100, and the transmission screw 211 in the first power mechanism 210 extends in the direction close to the bottom plate 120 of the frame 100, and the film sealing mechanism 220 is transmission-connected to the transmission screw 211; the carrier assembly 300 includes a second power mechanism 310 and a carrier 320, a second power mechanism 310 is arranged on the bottom plate 120 of the frame 100, and the second power mechanism 310 is transmission-connected to the carrier 320. Along the X direction, the second power mechanism 310 drives the carrier 320 to extend through the opening or retract into the film sealing chamber; the door body assembly 400 includes a door panel 410 and a reset member 420. The door panel 410 is rotatably connected to the bottom plate 120 corresponding to the opening, and the reset member 420 is arranged between the bottom plate 120 and the door panel 410 to drive the door panel 410 to close.

[0049] Because the first power mechanism 210 is disposed on the top plate 110, and the film sealing mechanism 220 is transmission-connected to a drive screw 211 extending toward the bottom plate 120, when sealing, the first power mechanism 210 is activated, and the rotation of the drive screw 211 drives the film sealing mechanism 220 upward or downward to complete the film sealing of the multi-well plate to be sealed, which is placed on the carrier 320. During the entire film sealing process, the film sealing mechanism 220 is driven by the drive screw 211, and the drive screw 211 extends in the Z direction, thereby improving the operational stability of the film sealing mechanism 220.

[0050] Since the corresponding bottom plate 120 is rotatably connected to the bottom plate 120, and a reset member 420 is provided between the door panel 410 and the bottom plate 120; at the same time, the carrier 320 is movably provided on the bottom plate 120 along the X direction. Before film sealing, the second power mechanism 310 is activated to drive the carrier 320 to move in the direction close to the opening, and at the same time, the carrier 320 pushes the door panel 410 to rotate and open, so that the carrier 320 can extend out of the opening; after the carrier 320 extends out of the opening, the porous plate to be sealed is placed on the carrier 320; then the second power mechanism 310 is activated again to drive the carrier 320 to move toward the film sealing chamber, and the carrier 320 releases the pushing force on the door panel 410. At the same time, the reset member 420 drives the door panel 410 to automatically rotate and close, so that the porous plate located in the film sealing chamber can be sealed. During the entire process, as the carrier 32 moves, the carrier 320 and the door panel 410 are linked together, avoiding manual opening or closing of the door panel 410 during the entire sealing process, thereby improving the smoothness of the sealing and shortening the time of the pre-sealing process, thereby reducing the probability of sample loss and spatial cross-contamination caused by evaporation and leakage of the sample liquid in the well plate.

[0051] In some other embodiments, the door panel 410 can be rotatably connected to the housing 500 corresponding to the opening according to actual needs, that is, the door panel 410 can be set to a top-opening type or a side-opening type.

[0052] Preferably, the first power mechanism 210 also includes a first driving member 212, a first transmission chain 213, a screw nut 214 and at least two first transmission sprockets 215. The two ends of the transmission screw 211 are movably connected to the top plate 110 and the bottom plate 120 respectively. The screw nut 214 is sleeved on the transmission screw 211 and fixedly connected to the film sealing mechanism 220. The first driving member 212 is arranged on the top plate 110, one of the first transmission sprockets 215 is connected to the output shaft of the first driving member 212, and the other first transmission sprocket 215 is connected to the transmission screw 211. The two first transmission sprockets 215 are connected by the first transmission chain 213.

[0053] Specific combination Figure 3 As shown, in order to further improve the stability and reliability of the first power mechanism 210 in driving the film sealing mechanism 220 to rise or fall, and to improve the flatness and uniformity of the film sealing mechanism 220 when sealing the film, in this embodiment, the first driving member 212 is configured as a forward and reverse motor, and the motor shaft of the forward and reverse motor is arranged perpendicular to the top plate 110, and two transmission screws 211 are provided. Both ends of the two transmission screws 211 are movably connected to the top plate 110 and the bottom plate 120. Correspondingly, three first transmission sprockets 215 are provided, one of which is connected to the output shaft of the first driving member 212, and the other two first transmission sprockets 215 are connected one by one to the two transmission screws 211. The three first transmission sprockets 215 are connected by a first transmission chain 213.

[0054] When the film sealing of the porous plate is needed, the forward and reverse motors rotate forward, and simultaneously drive the first transmission sprocket 215 connected on the motor shaft to rotate forward, and drive two first transmission sprockets 215 to rotate forward by the first transmission chain 213, thereby realizing that the transmission screw 211 rotates forward, and the transmission screw 211 is in forward rotation, and the screw nut 214 moves downward along the transmission screw 211, thereby driving the film sealing mechanism 220 to descend, and realizing the film sealing of the target porous plate. After the film sealing of the target porous plate is finished, the forward and reverse motors rotate in the opposite direction, and simultaneously drive the first transmission sprocket 215 connected on the motor shaft to rotate in the opposite direction, and drive two first transmission sprockets 215 to rotate in the opposite direction by the first transmission chain 213, thereby realizing that the transmission screw 211 rotates in the opposite direction, and the screw nut 214 moves upward along the transmission screw 211, thereby driving the film sealing mechanism 220 to rise, so that the subsequent process of the porous plate of film sealing is carried out.

[0055] Alternatively, it can be configured such that the motor shaft of the forward and reverse motor is directly connected to the transmission screw 211 , and the forward and reverse motor directly drives the transmission screw 211 to rotate forward or reverse.

[0056] Preferably, the film sealing mechanism 220 includes a first heat insulation plate 221 and a heating block 222 . The first heat insulation plate 221 is connected to the screw nut 214 . The heating block 222 is fixedly connected to the first heat insulation plate 221 and is located below the first heat insulation plate 221 .

[0057] Specific combination Figure 2 and Figure 3 As shown, the heating block 222 and the first heat insulation plate 221 are both arranged horizontally. The heating plate is used to generate heat and, driven by the first power mechanism 210, seals the film to be sealed and the orifice plate; the first heat insulation plate 221 is used to separate the heating block 222 and the top plate 110, thereby reducing the heat generated by the heating block 222 from being transferred to the top plate 110, avoiding the situation where excessive heat at the top plate 110 affects the performance of the first transmission chain 213.

[0058] Preferably, the film sealing device further includes a tensioning assembly 230 , which includes a connecting member 231 and an idler wheel 232 . The idler wheel 232 is connected to the top plate 110 via the connecting member 231 and abuts against the first transmission chain 213 to tension the first transmission chain 213 .

[0059] Specific combination Figure 3As shown, the idler wheel 232 is movably connected to the connecting member 231 and abuts against the first transmission chain 213. By adjusting the relative position of the idler wheel 232 and the connecting member 231, the tightness of the first transmission chain 213 can be changed without affecting the normal transmission of the first transmission chain 213, thereby ensuring the normal operation of the transmission screw 211.

[0060] In an optional technical solution of this embodiment, the film sealing device further includes a first guide and limit assembly, which is disposed between the side upright plate 130 of the frame 100 and the first heat insulation plate 221. Specifically, a guide rail 341 is disposed on each side of the two side upright plates 130 adjacent to each other, and the guide rail 341 extends along the Z direction. Two corresponding slide grooves are disposed on the first heat insulation plate 221, and the two slide grooves slidably engage with the two slide rails 341 in a one-to-one correspondence. These grooves serve as guides and limiters during the ascent or descent of the film sealing mechanism 220, ensuring that the film sealing mechanism 220 always moves along the Z direction, thereby improving the film sealing effect.

[0061] In addition, in this embodiment, two support rods 140 are provided, with both ends of the two support rods 140 fixedly connected to the bottom plate 120 and the top plate 110, respectively. The two support rods 140 are provided in a one-to-one correspondence with the two side plates 130 and are both located behind the corresponding side plates 130. The two support rods 140 and the two side plates 130 cooperate with each other to improve the connection stability between the top plate 110 and the bottom plate 120, thereby extending the service life of the frame 100 and the film sealing instrument.

[0062] In an optional technical solution of this embodiment, the film sealing instrument further includes a housing 500, a second heat shield 600, and / or a radiator 700. The housing 500 is mounted on the frame 100 to enhance the overall aesthetics of the film sealing instrument. The first driver 212 is located below the top plate 110, ensuring the driving effect of the film sealing mechanism 220 while improving the space utilization within the frame 100, thereby reducing the spatial volume of the film sealing instrument. The second heat shield 600 is disposed between the first driver 212 and the film sealing mechanism 220 to reduce the heat generated by the heating block 222 from being transferred to the first driver 212, thereby preventing excessive heat from being generated at the first driver 212 and affecting the performance of the first driver 212. The radiator 700 is disposed between the housing 500 and the frame 100 to dissipate excess heat generated by the heating block 222, thereby preventing excessive heat from accumulating at the housing 500 and affecting the performance and service life of the housing 500.

[0063] Preferably, the reset member 420 is configured as a torsion spring, the door body assembly 400 also includes a door shaft, the door panel 410 is rotatably connected to the base plate 120 via the door shaft, the torsion spring is sleeved on the door shaft, and the torsion sections at both ends of the torsion spring are fixedly arranged on the base plate 120 and the door panel 410 respectively.

[0064] Specific combination Figure 6 As shown, a clearance groove is provided at the connection between the bottom plate 120 and the door panel 410 to ensure that when the door panel 410 connected to the bottom plate 120 is fully closed, the door panel 410 is flush with the outer wall of the housing 500, thereby improving the overall aesthetics of the film sealing instrument. The door assembly 400 also includes two fixing seats 430, which are provided on the bottom plate 120 and located on either side of the clearance groove. The ends of the door shaft are rotatably connected to the two fixing seats 430, and the door panel 410 is transmission-connected to the door shaft. The torsion sections at both ends of the torsion spring are recorded as the first torsion section and the second torsion section. The torsion spring is sleeved behind the door shaft, the first torsion section is fixedly arranged on the side wall of the avoidance groove, and the second torsion section is fixedly arranged on the door panel 410; when the carrier 320 pushes the door panel 410 to be opened, the torsion spring is subjected to force as a whole, and the second torsion section rotates in the direction away from the first torsion section; in the process of retraction of the carrier 320, the thrust of the carrier assembly 300 on the door panel 410 is reduced, that is, the torsion force on the torsion spring is reduced, and the second torsion section rotates autonomously in the direction close to the first torsion section, thereby driving the door panel 410 to rotate in the direction close to the opening; when the carrier 320 is retracted into the film sealing cavity, the door panel 410 is no longer subjected to the thrust of the carrier assembly 300, the torsion spring returns to its original state, and the door panel 410 is completely closed with the cooperation of the first torsion section and the second torsion section, so as to facilitate the subsequent film sealing of the porous plate.

[0065] In some other embodiments, the reset member 420 can also be configured as a tension spring and / or a rubber strip, and the tension spring or rubber strip is arranged between the outer wall of the shell 500 and the door panel 410. When the carrier 320 pushes the door panel 410 to be opened, the tension spring and / or the rubber strip is stretched; when the carrier 320 retracts, the thrust applied to the tension spring and / or the rubber strip decreases, and the tension spring and / or the rubber strip gradually retracts to drive the door panel 410 to rotate toward the opening, until the carrier 320 retracts into the sealing film cavity, and the tension spring and / or the rubber strip returns to its original state and drives the door panel 410 to be completely closed.

[0066] Preferably, the carrier assembly 300 further includes a guide wheel 330 rotatably connected to the side of the carrier 320 proximate the door panel 410. As the carrier 320 extends from the opening, the guide wheel 330 contacts and rotates with the door panel 410, thereby pushing the door panel 410 open. This allows for a smoother opening of the door panel 410 and prevents direct contact between the carrier 320 and the door panel 410, potentially damaging the door panel 410 or the carrier 320. To ensure synchronous rotation of the door panel 410, multiple guide wheels 330 are spaced apart along the width of the carrier 320 on the side proximate the door panel 410. In this embodiment, two guide wheels 330 are spaced apart on the side proximate the door panel 410, and the two guide wheels 330 are symmetrically arranged about the centerline of the carrier 320.

[0067] Preferably, the carrier assembly 300 further includes a second guide and limit assembly 340, through which the carrier 320 is slidably connected to the base plate 120. The second guide and limit assembly 340 is provided to facilitate the movement of the carrier 320 along the X direction. At the same time, during the movement of the carrier 320 along the X direction, the second guide and limit assembly 340 guides the carrier 320, guiding the carrier 320 to always move along a predetermined route to ensure the overall use effect of the film sealing instrument. When the carrier 320 is located in the film sealing chamber, the second guide and limit assembly 340 limits the carrier 320 to prevent the carrier 320 from shifting along its width direction, which would cause the porous plate placed on the carrier 320 to shake and tip over, thereby ensuring the film sealing effect of the porous plate. Specifically, the second guide and stop assembly 340 includes a slide rail 341 and a slide seat 342. One of the slide rail 341 and the slide seat 342 is mounted on the carrier 320, while the other is mounted on the base plate 120. The slide rail 341 and the slide seat 342 are slidably connected, and the slide rail 341 extends along the X-direction. In this embodiment, the slide seat 342 is mounted on the base plate 120, and the slide rail 341 is mounted on the carrier 320. Two sets of second guide and stop assemblies 340 are spaced apart along the width of the carrier 320. The two sets of second guide and stop assemblies 340 are symmetrically arranged about the centerline of the carrier 320, further enhancing the convenience and stability of the carrier 320 during movement along the X-direction.

[0068] Preferably, the second power mechanism 310 includes a second drive member 311 and a transmission assembly. The second drive member 311 is disposed on the base plate 120, and the transmission assembly is in transmission connection between the second drive member 311 and the carrier 320. The second drive member 311 is configured as a forward and reverse motor, providing power to the carrier 320 during its extension or retraction into the film sealing chamber. The forward and reverse rotation of the forward and reverse motor drives the carrier 320 to reciprocate along the X-direction, thereby ensuring smoothness and stability during the reciprocating motion of the carrier 320. The transmission assembly is in transmission connection between the second drive member 311 and the carrier 320, enabling the second drive member 311 to drive the reciprocating motion of the carrier 320 while avoiding interference caused by the direct connection between the carrier 320 and the second drive member 311.

[0069] In this embodiment, the transmission assembly includes a second transmission chain 312, a fixing member 313 and two second transmission sprockets 314, wherein one second transmission sprocket 314 is fixedly connected to the output shaft of the forward and reverse motor, and the other second transmission sprocket 314 is rotatably connected to the end surface of the carrier 320 close to the bottom plate 120. The two second transmission sprockets 314 are connected to each other through the second transmission chain 312, and the fixing member 313 is connected between the carrier 320 and the second transmission chain 312. Figure 1As shown, the opening of the film sealing cavity is set on the front wall of the shell 500, and the second driving member 311 is set on the bottom plate 120 opposite the opening to ensure that the carrier 320 reciprocates along the X direction. In order to ensure that the stroke of the carrier 320 meets actual needs, the second driving member 311 is set close to the rear wall of the shell 500, and the motor shaft of the forward and reverse motor is set perpendicular to the bottom plate 120. This ensures the normal operation of the carrier 320 while reducing the probability of interference between the forward and reverse motors and the carrier 320. When the forward and reverse motors rotate forward, they drive the second transmission sprocket 314 connected to the motor shaft to rotate forward. Under the transmission action of the second transmission chain 312, the other second transmission sprocket 314 rotates forward synchronously. During this process, the fixing member 313 connected to the second transmission chain 312 moves in the direction close to the opening, thereby driving the carrier 320 connected to the fixing member 313 to move in the direction close to the opening and extend out of the opening. After the porous plate to be sealed is placed on the carrier 320, the forward and reverse motors are reversed, thereby driving the second transmission sprocket 314 connected to the motor shaft to rotate in the opposite direction. Under the transmission action of the second transmission chain 312, the other second transmission sprocket 314 rotates in the opposite direction synchronously; in this process, the fixing member 313 connected to the second transmission chain 312 moves in the direction away from the outlet, thereby driving the carrier 320 connected to the fixing member 313 to move in the direction away from the outlet. After the carrier 320 is completely located in the film sealing chamber, the forward and reverse motors stop running to ensure the stability of the carrier 320 in the film sealing chamber, so as to facilitate the subsequent film sealing of the porous plate.

[0070] In other embodiments, the transmission assembly includes a gear (not shown) and a rack (not shown). The gear is fixedly connected to the output end of the second drive member 311, and the rack is disposed on the end surface of the carrier 320 near the base plate 120, with the gear and rack meshing. Specifically, the second drive member 311 is also configured as a forward / reverse motor, with the output shaft of the drive motor perpendicular to the base plate 120. The gear is fixedly sleeved on the output shaft, and the gear and rack mesh. As the forward / reverse motor rotates forward or reverse, the meshing position of the gear and rack changes, thereby driving the carrier 320, which is connected to the rack, to extend or retract within the sealing chamber.

[0071] In other embodiments, the second power mechanism 310 can be directly configured as a push rod motor. Specifically, the push rod motor is disposed on the base plate 120, and the output shaft of the push rod motor is arranged parallel to the base plate 120 and is in driving connection with the carrier 320. When the push rod motor is activated and the output shaft extends, the carrier 320 is driven to extend out of the opening; when the output shaft retracts, the carrier 320 is driven to retract into the film sealing chamber.

[0072] Preferably, the film sealing instrument also includes a control component 800 and multiple sensing components 900. The multiple sensing components 900 are arranged on the frame 100 and are used to sense the relative positions of the film sealing mechanism 220 and the carrier 320. The control component 800 is controlled and connected with the first power mechanism 210, the second power mechanism 310 and the multiple sensing components 900.

[0073] Specific combination Figure 1 and Figure 7 As shown, two sensing members 900 are provided, denoted as a first sensing member and a second sensing member. The first sensing member is provided on the bottom plate 120 and is provided near the rear wall of the housing 500, and the second sensing member is provided on the side plate 130. When the first power mechanism 210 drives the film sealing mechanism 220 to rise or fall, the second sensing member is used to sense the relative position of the film sealing mechanism 220 within the film sealing chamber. When the second sensing member senses that the film sealing mechanism 220 has descended to contact the porous plate, or has risen to contact the top plate 110, the second sensing member sends a stop signal to the controller. When the second power mechanism 310 receives the stop signal, it stops operating, thereby preventing the film sealing mechanism 220 from damaging the porous plate or the frame 100 due to excessive descent or rise. When the second power mechanism 310 drives the carrier 320 to retract into the film sealing chamber, the first sensor senses the carrier 320 and sends a stop signal to the control unit 800. The control unit 800 receives the stop signal and stops the second power mechanism 310. This ensures that the carrier 320 is fully retracted into the film sealing chamber while preventing excessive retraction and interference with the rear wall of the housing 500. Furthermore, a display screen connected to the control unit 800 is provided on the housing 500, allowing the operator to operate the film sealing instrument directly through the display screen.
