[0070] In an embodiment, Figure 1 The structure schematic diagram of the film sealing part provided by an embodiment of the present application is shown in Figure 2 The structure schematic diagram of the film feeding part provided by an embodiment of the present application is shown in Figures 1-2 As shown in the drawings, the present application provides a film sealing instrument, which comprises a film sealing part 2 and a film feeding part 3.

[0071] The film sealing part 2 comprises a film sealing motor 21 and a hopper 23, the hopper 23 is used for placing a piece to be sealed 22, and the film sealing motor 21 is used for controlling the hopper 23 to move in the horizontal direction in the film sealing part 2, thereby driving the piece to be sealed 22 to move; the hopper 23 comprises a first baffle 231; wherein the piece to be sealed 22 can be a deep hole plate, a micro-hole plate 5, a PCR plate (Polymerase Chain Reaction Plate) and the like. The film feeding part 3 comprises a guide groove 31, a film feeding roller 33 and a pressing device 34; the sealing plate film 1 and the piece to be sealed 22 are sealed through cooperation of the guide groove 31, the film feeding roller 33 and the pressing device 34, wherein the pressing device 34 has elasticity, and the pressing device 34 comprises but is not limited to a rubber-coated roller, a roller with a spring and a guide shaft or a flat plate.

[0072] The film feeding part 3 comprises a guide groove 31, a film feeding roller 33 and a pressing device 34; the sealing plate film 1 and the piece to be sealed 22 are sealed through cooperation of the guide groove 31, the film feeding roller 33 and the pressing device 34, wherein the pressing device 34 has elasticity, and the pressing device 34 comprises but is not limited to a rubber-coated roller, a roller with a spring and a guide shaft or a flat plate. Figure 3 The structure schematic diagram of the sealing plate film provided by an embodiment of the present application is shown in Figure 3 As shown in the drawings, the sealing plate film 1 has a cutting line 13, the part with smaller area on one side of the cutting line 13 is a fixed part 12, the part with larger area on the other side is a cutting part 11, the cutting part 11 has a sealing layer 14 and a protective layer 15, the protective layer 15 can be separated from the sealing layer 14, and the surface of the sealing layer 14 has adhesive glue; wherein one sealing plate film 1 corresponds to one piece to be sealed 22, and the adhesive glue can be pressure-sensitive adhesive.

[0073] The film feeding part 3 comprises a guide groove 31, a film feeding roller 33 and a pressing device 34; the sealing plate film 1 and the piece to be sealed 22 are sealed through cooperation of the guide groove 31, the film feeding roller 33 and the pressing device 34, wherein the pressing device 34 has elasticity, and the pressing device 34 comprises but is not limited to a rubber-coated roller, a roller with a spring and a guide shaft or a flat plate.Figure 4 A film tearing principle diagram provided by an embodiment of the application, Figure 5 A film feeding position structure diagram provided by an embodiment of the application, as shown in Figures 1-5 The guide groove 31 is provided with a guide protrusion 32, and the film feeding roller 33 drives the sealing plate film 1 to run forward by rotation through friction, and moves the sealing plate film 1 along the guide groove 31 through the guide groove 31, and makes the sealing plate film 1 reach the film feeding position along the guide protrusion 32 at a specific angle. When the first baffle 231 moves to the film feeding position, the guide protrusion 32, the pressing device 34 and the first baffle 231 gradually overlap and press the fixed part 12 of the sealing plate film 1 in turn. When the guide protrusion 32 abuts against the cutting line 13 of the sealing layer 14 of the sealing plate film 1, the protective layer 15 starts to peel off from the cutting line 13 and the sealing layer 14. As the first baffle 231 moves along the direction from the guide protrusion 32 to the pressing device 34 (i.e. the hopper 23 moves to the left), the protective layer 15 gradually peels off from the sealing layer 14, and the sealing layer 14 adheres to the film to be sealed 22. As the film to be sealed 22 moves, the pressing device 34 presses the sealing layer 14 and the film to be sealed 22, and the protective layer 15 separates from the sealing plate film 1 and moves along the initial angle of the sealing plate film 1 in the direction opposite to the movement direction of the sealing layer 14 (i.e. the protective layer 15 moves to the right, and the sealing layer 14 moves to the left).

[0074] The contact surface of the guide protrusion 32 and the sealing plate film 1 can be a circular arc or an angle, and the radius of the circular arc or the angle of the guide protrusion 32 can be adapted by the user as needed.

[0075] The guide protrusion 32 can be a protrusion on the guide groove 31, or a separate structure. Figure 6 A partial diagram of the guide protrusion provided by an embodiment of the application, Figure 7 A partial diagram of the guide protrusion provided by another embodiment of the application, as shown in Figures 6-7 The guide protrusion 32 can include a roller 321. In an embodiment, as shown in Figure 6 The roller 321 is partially embedded in the protruding part of the guide protrusion 32, and the surface of the roller 321 is used to contact the sealing plate film 1. The diameter of the roller 321 can be less than 1 mm. In another embodiment, as shown in Figure 7 The roller 321 can be separated from the guide protrusion 32, and the outer surface of the roller 321 contacts the sealing plate film 1. The roller 321 is fixed by punching a hole in the film feeding part housing.

[0076] The application is a small sealing film instrument, and the basic size of the instrument is 450mm*114mm*149mm. The instrument can be used as a small independent device or can be used in a liquid processing platform workstation.

[0077] The technical scheme provided by the above embodiment of the application realizes the functions of automatically separating the sealing layer 14 and the protective layer 15 of the sealing plate film 1 and automatically sealing the to-be-sealed film piece 22, and makes the sealing plate film 1 stable during the separation process, avoids damage of the sealing plate film 1 due to improper operation, does not damage the structure of the to-be-sealed film piece 22 like the heat sealing method, makes the sealed film easier to tear, and reduces the occupied space and cost of the film sealing instrument.

[0078] In an embodiment, Figure 8 The raw material box structure provided by the embodiment of the application is shown in a whole schematic view as Figure 8 The film sealing instrument further comprises a raw material box 4 arranged at the top end of the film feeding part 3. The raw material box 4 comprises an upper shell 41, a bottom plate 42 and a pressing block 43. The pressing block 43 is provided with a cylindrical pin at one end, the cylindrical pin passes through a cylindrical pin positioning hole 46 of the upper shell 41 so that the pressing block 43 is arranged between the upper shell 41 and the bottom plate 42. The sealing plate film 1 is placed between the pressing block 43 and the bottom plate 42, and the pressing block 43 is used to apply pressure to the sealing plate film 1 to press the sealing plate film 1 into the film feeding part 3.

[0079] The feeding sequence of the sealing plate film 1 in the film feeding part 3 can be adjusted by adjusting the fixed height of the related parts in the film feeding part 3, that is, the feeding sequence of the sealing plate film 1 in the film feeding part 3 can be from bottom to top or from top to bottom.

[0080] In an embodiment, Figure 9 The raw material box structure provided by the embodiment of the application is shown in a cross-sectional schematic view as Figure 9 The raw material box 4 further comprises a first magnet 44 and a second magnet 45. The first magnet 44 is arranged in the upper shell 41, and the second magnet 45 is arranged in the pressing block 43. The second magnet 45 repels the first magnet 44 magnetically, so that the pressing block 43 rotates around the cylindrical pin and applies pressure to the sealing plate film 1. Due to the repulsive force between the first magnet 44 and the second magnet 45, the lowest sealing plate film 1 in the raw material box 4 keeps in contact with the film feeding roller 33. The first magnet 44 and the second magnet 45 can be springs or other devices that enable the pressing block 43 to rotate around the cylindrical pin and apply pressure to the sealing plate film 1.

[0081] In an embodiment, as Figure 2 The film feeding part 3 further comprises a pressure plate 35 and a spring 36. One end of the spring 36 is fixed to the shell of the film feeding part 3, and the other end of the spring 36 is bonded to the other end of the pressure plate 35, for applying pressure to the pressure plate 35. One end of the pressure plate 35 is tangentially arranged with the film feeding roller 33, and a plurality of sealing plate films 1 are separated by the pressure applied to the pressure plate 35 by the spring 36.

[0082] Specifically, when the film feeding roller 33 drives the sealing plate film 1 to move forward, the sealing plate film 1 will be pressed when it reaches the pressure plate 35. The friction between the film feeding roller 33 and the sealing plate film 1 is greater than the friction between the two sealing plate films 1 and the friction between the sealing plate film 1 and the pressure plate 35, so that only one sealing plate film 1 is sent at a time. The use of only one sealing plate film 1 corresponding to the film to be sealed 22 reduces unnecessary waste of sealing plate films 1.

[0083] In an embodiment, as shown in Figure 2 The film feeding part 3 further includes a page separator 37 arranged tangentially with the film feeding roller 33 to separate multiple sealing plate films 1 and allow the film feeding part 3 to feed only one film at a time. When the sealing plate film 1 passes through the page separator 37, it is subjected to a certain pressure. According to the principle that the friction between the page separator 37 and the sealing plate film 1 and the friction between the film feeding roller 33 and the sealing plate film 1 are both greater than the friction between the two sealing plate films 1, the two sealing plate films 1 that cannot be separated after passing through the pressure plate 35 are separated. One sealing plate film 1 is blocked by the page separator 37, and the other sealing plate film 1 is normally fed. The normally fed sealing plate film 1 is fed along a specific angle to the film feeding position through the guide groove 31, ensuring that only one sealing plate film 1 is fed at a time.

[0084] In an embodiment, at least one light hole (not shown in the figure) is provided on the guide groove 31, as shown in Figure 2 The film feeding part 3 can further include an optical sensor 38 arranged correspondingly with the light hole. When the optical sensor 38 senses the sealing plate film 1 through the light hole, the film feeding part 3 stops running, ensuring that the cutting line 13 of the sealing plate film 1 corresponds to the guide protrusion 32 each time the film is fed.

[0085] In an embodiment, as shown in Figure 2 The film sealing instrument further includes a film feeding motor 39 for driving the film feeding roller 33 to rotate. The synchronous wheel transmission mode of the film feeding motor 39 and the film feeding roller 33 includes but is not limited to gear transmission, coaxial rotation and other transmission modes.

[0096] In an embodiment, Figure 17 A flow chart of the operation of the film sealing instrument is provided for an embodiment of the application, as shown in the figure, Figure 17 The operation procedure of the film sealing instrument is as follows:

[0097] Step S710: Place the stacked sealing film 1 in the raw material box 4;

[0098] Step S720: Place the film sealing object 22 in the film sealing part 2 at the initial work station;

[0099] Step S730: Set the corresponding operation procedure according to the specifications and models of the current sealing film 1 and the film sealing object 22, and click the start button;

[0100] Step S740: Determine the film feeding effect through the optical sensor 38;

[0101] When the film feeding motor 39 is running, if the optical sensor 38 has a signal, it is determined that the film feeding part 3 is jammed and an alarm is given;

[0102] When the film feeding motor 39 is running for 10s, if the optical sensor 38 does not sense a signal, it is determined that the sealing plate film 1 has not been loaded, and an alarm is given;

[0103] When the film feeding motor 39 is running for 10s, if the optical sensor 38 senses a signal, it is determined that the sealing plate film 1 has been loaded, and the film feeding part 3 stops feeding the film;

[0104] Step S750: After the film sealing part 2 moves from the initial position to the film sealing position, the film feeding part 3 feeds the sealing plate film 1 to the film feeding position and stops;

[0105] Step S760: The film sealing part 2 moves at a constant speed from the film sealing position to the initial position, until it reaches the initial position and completes the film sealing.

[0106] After the film sealing is completed, the protective layer 15 falls into the film sealing part 2 in the film sealing position; when the next group of film sealing is performed, the second baffle 232 will compress the protective layer 15 into the waste box 6 for storage as the film sealing part 2 moves, and the number of waste in the waste box 6 can be observed through the waste window 63; when the storage reaches a certain amount, the waste box 6 is emptied.

[0107] Since the existing film sealing instrument selects a film in a roll, there is a structure for feeding and winding the roll, and the winding structure can cause the roll film to have many edge materials, increasing the use cost of the film. In addition, the main film sealing structure makes the size of the entire film sealing instrument slightly large, which occupies a large space and is not conducive to use in a workstation, and the cost of the entire instrument is higher. At the same time, the heat sealing can damage the structure of the film to be sealed 22, and it is not easy to tear the sealed film.

[0108] The technical scheme provided by the present application realizes the functions of automatically separating the sealing layer 14 and the protective layer 15 of the sealing plate film 1 and automatically sealing the film to be sealed 22 through the cooperation of the guide protrusion 32, the first baffle 231 and the pressing device 34, and at the same time, the sealing plate film 1 remains stable during the separation process with the protective layer 15, avoiding damage to the sealing plate film 1 due to improper operation. Not only does it not damage the structure of the film to be sealed 22 like the heat sealing method, but it also makes it easier to tear the sealed film, reduces the occupied space and cost of the film sealing instrument, and seals the film to be sealed 22 in a way that one sealing plate film 1 corresponds to one film to be sealed 22, reducing the problem of many edge materials caused by the winding structure, and reducing unnecessary waste.
