Description

Technical Field

[0001] This application relates to the field of biochip technology, and more specifically, to a biochip packaging structure and its usage method. Background Technology

[0002] After biochips are manufactured, they need to be encapsulated for protection. Existing technology publication CN216636975U provides a biochip encapsulation structure. This device uses a support and baffle. After the biochip is manufactured, it is inserted into the support, and a positioning block is inserted into the groove of the biochip to fix its orientation. Then, a positioning rod is inserted into the groove of the support. After the positioning rod is inserted to the bottom of the groove, a spring pushes a locking block to insert into the positioning rod's slot, fixing the positioning rod inside the support. Simultaneously, the baffle is inserted into both ends of the support, and gaskets adhere to both sides of the biochip to limit its position. A filler strip is also pushed into the groove of the baffle to seal the gap between the baffle and the support. The device encapsulates and protects the biochip, preventing contact with harmful external substances and facilitating biochip encapsulation.

[0003] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: When the device removes the biochip, the baffle is pulled directly out of the support by hooking the control lever, thereby releasing the baffle from the biochip and directly pushing the biochip out of the support 3. However, at the same time as the baffle is released from the biochip, the pressure of the gas in the cavity between the sealed baffle and the support will change due to environmental factors. As a result, after the baffle is opened, the sealed biochip will quickly break free from the restraint of the encapsulation structure, causing the biochip to fall and posing a hazard. This is not conducive to the protection and use of the biochip by the device.

[0004] In view of this, we propose a biochip packaging structure and its usage method. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a biochip packaging structure that solves the technical problems mentioned in the background art and achieves the protective effect of removing and opening the biochip.

[0007] 2. Technical Solution

[0008] This application provides a biochip packaging structure, including a component housing, a transparent plexiglass sealing cap, a clamping component, an opening and closing assembly, and a transmission and suction assembly;

[0009] A transparent acrylic sealing cap is fitted onto the outside of the component housing;

[0010] The clamping component is located inside the component housing and is used to clamp and limit the biochip.

[0011] The opening and closing assembly is located at the bottom of the part housing;

[0012] The transmission suction assembly is located at the bottom of the part housing and is used to provide negative pressure protection for the sealed cavity formed by the snap-fit ​​seal between the transparent plexiglass sealing cover and the part housing.

[0013] The clamping component engages with the suction assembly via a transmission mechanism. The opening / closing assembly engages with the suction assembly via a transmission mechanism.

[0014] By adopting the above technical solution, the opening and closing component is manually pressed, which drives the clamping component to open and close multiple clamping plates in the clamping component while adjusting the height. This clamps and fixes the biochip, which not only improves the clamping and protection effect of the device on the biochip, but also facilitates the subsequent removal of the biochip, thus improving the safety protection of the device for the packaging and use of the biochip.

[0015] As an optional solution to the technical solution of this application, the inner sides of the part housing are fixedly connected with meshing tooth blocks, and the outer side of the part housing is fixedly connected with a mating sleeve. The mating sleeve is embedded with a sealing ring and is sleeved on the outside of the transparent organic glass sealing cover.

[0016] By adopting the above technical solution, a sealing ring can be used to seal the transparent organic glass sealing cover to the outside of the part housing.

[0017] As an optional embodiment of the technical solution in this application, the clamping component includes a lifting screw sleeve frame, a transmission screw shaft, and a supporting clamp. The lifting screw sleeve frame is slidably disposed within the part housing, and the transmission screw shaft is internally threadedly connected to the lifting screw sleeve frame, the transmission screw shaft being rotatably connected to the part housing. A driven bevel gear A is fixedly disposed at the lower end of the transmission screw shaft.

[0018] One end of the lifting screw sleeve extends through the part housing and is fixedly connected to a supporting sleeve. The lifting screw sleeve and the part housing are slidably sealed. The supporting sleeve has two side wall plates hinged to each other in a symmetrical structure. One end of each side wall plate is made of elastic rubber and has several meshing teeth fixedly connected to it. The meshing teeth are engaged with the meshing tooth blocks for transmission.

[0019] As an optional solution to the technical solution of this application, the supporting sleeve has a through groove on its outside, a plastic clamp is fixedly connected in the through groove, a rubber strip is fixedly connected to one side of the plastic clamp, a limiting groove is opened and closed on the other side of the plastic clamp, a limiting protrusion is slidably provided in the limiting groove, and the limiting protrusion is fixedly connected to the part housing.

[0020] By adopting the above technical solution, the lifting and adjusting operation of the clamping component causes the limiting protrusion fixed in the part housing to compress the plastic clamping plate to shrink, thereby clamping the placed biochip. The side wall clamping plate also further clamps and limits the placed biochip under the meshing transmission action of the meshing teeth and meshing tooth blocks, thereby improving the safety protection of the biochip after packaging.

[0021] As an optional solution to the technical solution of this application, the opening and closing assembly includes a shear clamp, an arc toothed plate, and a transmission toothed shaft;

[0022] There are two shear clamps, which are rotatably connected inside the part housing. The two shear clamps are rotatably mounted together. One of the shear clamps has an arc-tooth plate fixedly connected to one side. The arc-tooth plate and the axis of the rotatably connected shear clamp are located on the same axis. One end of the arc-tooth plate is engaged with a transmission gear shaft rotatably connected inside the part housing. One end of the transmission gear shaft is fixedly equipped with a driving bevel gear. The driving bevel gear is engaged with a driven bevel gear A on the transmission screw shaft.

[0023] As an optional solution to the technical solution of this application, a fan-shaped resetter is fixedly connected to the other side of another shear clamp. The resetter consists of an arc-shaped pressure rod, an arc-shaped pressure sleeve, and a compression spring. The axis of the resetter is located on the same axis as the axis of the rotatably connected shear clamp, and the other end of the resetter is fixedly connected to the inside of the part housing.

[0024] By adopting the above technical solution, the opening and closing components can drive the clamping components to lift and hold the biochip while simultaneously driving the transmission suction components to suction the gas in the sealed cavity. This achieves both the safety protection and ease of use of the device for the biochip and optimizes the flexibility of the device's packaging operation.

[0025] As an optional solution to the technical solution of this application, the transmission suction assembly includes a piston plate, a screw sleeve and a transmission screw; the piston plate is slidably disposed in the suction chamber opened inside the part housing, a suction chamfer is opened on one side of the piston plate, and a screw sleeve is fixedly connected to one side of the piston plate, the screw sleeve being slidably and sealingly located inside the part housing.

[0026] As an optional embodiment of the technical solution in this application, the screw sleeve is internally threaded and equipped with a matching transmission screw. The transmission screw is rotatably connected to the inside of the part housing via a rotating seat. One end of the transmission screw is fixedly equipped with a driven bevel gear B; and the driven bevel gear B is meshed with the driven bevel gear A of the transmission screw shaft. Both driven bevel gears B mesh with the driving bevel gear.

[0027] By adopting the above technical solution, the suction chamfer on one side of the piston plate facilitates the evacuation of gas from the sealed cavity connected to the suction chamber.

[0028] A method of using a biochip packaging structure includes the following steps:

[0029] S1. When clamping and installing the biochip, first manually press the shear clamp. The shear clamp is driven by the meshing of the arc tooth plate and the transmission tooth shaft. The transmission screw shaft is rotated by the active bevel gear and the driven bevel gear A, which pushes the storage support sleeve to move upward.

[0030] S2. While the supporting sleeve moves upward, the plastic clamping plate slides with the limiting protrusion fixedly installed on the inner wall of the part housing, so that the plastic clamping plate expands outward during the upward movement. The side wall clamping plate engages with the meshing tooth block fixedly installed on the inner wall of the part housing through meshing teeth, and flips the closed side wall clamping plate outward.

[0031] S3. At this time, the transmission screw shaft drives the transmission screw to rotate through the driven bevel gear A and the driven bevel gear B, which pushes the threaded sleeve that is limited to the external threaded connection of the transmission screw outward, thereby pushing the piston plate that is fixedly connected to one end of the threaded sleeve out of the suction chamber opened in the part housing. The gas in the chamber is then filled into the sealed cavity formed by the part housing and the transparent plexiglass sealing cover through the air hole that communicates with the part housing, thus opening the transparent plexiglass sealing cover.

[0032] S4. Finally, insert the biochip to be packaged into the support sleeve for clamping and limiting. After the transparent plexiglass sealing cover is put on, release the shear clamp, and the compression limit reset device is reset, thereby driving the clamping component to firmly clamp and limit the placed biochip, and causing the transmission suction component to suction the sealed cavity, firmly adsorbing and fixing the transparent plexiglass sealing cover.

[0033] S5. After the biochip is packaged, manually press the shear clamp to move the supporting sleeve upwards, which in turn causes the two side wall clamps to flip outwards. At the same time, the two plastic clamps expand outwards during the upward movement, thus removing the clamping limit on the biochip and making it easy and quick to remove the packaged biochip.

[0034] 3. Beneficial effects

[0035] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0036] 1. This application uses a manually pressed opening and closing component to drive the clamping component with indirect meshing transmission to open and close multiple clamping plates in the clamping component while adjusting the height, thereby clamping and fixing the biochip. This not only improves the clamping and protection effect of the device on the biochip, but also facilitates the subsequent removal of the biochip, and improves the safety protection of the device for the packaging and use of the biochip.

[0037] 2. This application uses the lifting and adjusting operation of the clamping component to cause the limiting protrusion fixed in the part housing to compress the plastic clamping plate to shrink, thereby clamping the placed biochip. The side wall clamping plate also further clamps and limits the placed biochip under the meshing transmission action of the meshing teeth and meshing tooth blocks, thereby improving the safety protection of the biochip after packaging.

[0038] 3. This application utilizes the opening and closing component to drive the clamping component to lift and hold the biochip while simultaneously driving the transmission suction component to suction the gas inside the sealed cavity. This achieves both the safety protection and ease of use of the device for the biochip and optimizes the flexibility of the device's packaging operation.

[0039] 4. When the shear clamp drives the arc tooth plate to mesh with the transmission gear shaft, the transmission gear shaft drives the transmission screw shaft to mesh and drive, while indirectly driving the transmission screw to rotate. This causes the threaded sleeve connected to the external thread of the transmission screw to push and pull the piston plate to draw gas from the sealed cavity, firmly adsorbing and fixing the transparent organic glass sealing cover to the outside of the part housing, thereby improving the sealing and protection effect of the device for biochip packaging.

[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] Reference Figure 1 and Figure 2 A biochip packaging structure includes a component housing 1, a transparent plexiglass sealing cover 2, a clamping component 3, an opening and closing assembly 4, and a transmission and suction assembly 5.

[0049] A transparent acrylic sealing cover 2 is fitted onto the outside of the component housing 1;

[0050] The clamping component 3 is disposed inside the part housing 1 and is used to clamp and limit the biochip.

[0051] The opening and closing assembly 4 is located at the bottom of the part housing 1;

[0052] The transmission suction assembly 5 is located at the bottom inside the part housing 1, and is used to provide negative pressure protection for the sealed cavity formed by the snap-fit ​​seal between the transparent plexiglass sealing cover 2 and the part housing 1. The clamping component 3 is engaged with the suction assembly 5 for transmission. The opening and closing component 4 is engaged with the transmission suction assembly 5 for transmission.

[0053] In this technical solution, by manually pressing the opening and closing component 4, the opening and closing component 4 drives the clamping component 3, which is indirectly engaged and driven, to open and close multiple clamping plates in the clamping component 3 while adjusting its height. This facilitates the clamping and removal of the biochip. At the same time, the suction component 5, which is engaged and driven with the clamping component 3, suctions gas from the sealed cavity formed by the fitting of the component housing 1 and the transparent plexiglass sealing cover 2. This firmly seals and adsorbs the transparent plexiglass sealing cover 2 onto the outside of the component housing 1, thus providing a sealed protection for the encapsulated biochip.

[0054] Reference Figure 3 and Figure 4The inner sides of the housing 1 are fixedly connected with meshing tooth blocks 11, and the outer side of the housing 1 is fixedly connected with a mating sleeve 12; the mating sleeve 12 can be fitted and sealed to the transparent organic glass sealing cover 2, and a sealing ring is embedded in the mating sleeve 12.

[0055] The clamping component 3 includes a lifting screw sleeve 31, a transmission screw shaft 32, and a supporting clamp 33.

[0056] The lifting screw sleeve bracket 31 is slidably installed inside the part housing 1. The lifting screw sleeve bracket 31 is internally threaded with a transmission screw shaft 32, which is rotatably connected to the part housing 1. A driven bevel gear A39 is fixedly installed at the lower end of the transmission screw shaft 32.

[0057] The lifting screw sleeve bracket 31 extends through the part housing 1 into its interior and is fixedly connected to a supporting sleeve 33. The lifting screw sleeve bracket 31 and the part housing 1 are slidably sealed. The supporting sleeve 33 has two side wall plates 34 with a symmetrical structure and hinged on its exterior. One end of the side wall plate 34 is made of elastic rubber, and the other end is fixedly connected to a number of meshing teeth 35. The meshing teeth 35 are meshed with the meshing tooth block 11 for transmission.

[0058] The supporting sleeve 33 has a through groove, and two plastic clamps 36 are fixedly connected in the through groove. A rubber strip is fixedly connected to one side of the plastic clamp 36, and a limiting groove 37 is opened and closed on the other side of the plastic clamp 36. A limiting protrusion 38 that is fixedly connected to the part housing 1 is slidably fitted in the limiting groove 37.

[0059] In this technical solution, the lifting screw sleeve 31 is raised and lowered along the inside of the part housing 1 by rotating the transmission screw shaft 32, thereby driving the side wall clamping plate 34 to engage and rotate with the meshing tooth block 11, so that the side wall clamping plate 34 firmly clamps and limits the side of the held biochip. At the same time, the plastic clamping plate 36 is further clamped to the side wall of the held biochip under the squeezing action of the limiting protrusion 38, thereby improving the stability of the clamping component 3 in clamping and protecting the biochip.

[0060] Reference Figure 5 and Figure 6 The opening and closing assembly 4 includes a shear clamp 41, an arc toothed plate 42, and a transmission gear shaft 43;

[0061] There are two shear clamps 41, which are rotatably connected inside the part housing 1 and are rotatably mounted together. One of the shear clamps 41 has an arc toothed plate 42 fixedly connected to one side. The arc toothed plate 42 and the shear clamp 41 are on the same axis, and one end of the arc toothed plate 42 is engaged with a transmission gear shaft 43. The transmission gear shaft 43 is rotatably connected inside the part housing 1, and one end of the transmission gear shaft 43 is fixedly equipped with a driving bevel gear 45. The driving bevel gear 45 is engaged with a driven bevel gear A39 on the transmission screw shaft 32.

[0062] Another shear clamp 41 is fixedly connected to one side with a fan-shaped resetter 44. The resetter 44 consists of an arc-shaped pressure rod, an arc-shaped pressure sleeve and a compression spring. The arc-shaped pressure rod is slidably sleeved inside the arc-shaped pressure sleeve, and the two are elastically connected and fixed by the compression spring. The axis of the resetter 44 is on the same axis as the axis of the rotatably connected shear clamp 41, and the other end of the resetter 44 is fixedly connected to the inside of the part housing 1.

[0063] The transmission suction assembly 5 includes a piston plate 51, a screw sleeve 52, and a transmission screw 53;

[0064] The piston plate 51 is slidably disposed within the suction chamber inside the part housing 1. A suction chamfer is provided on one side of the piston plate 51, and a threaded sleeve 52 is fixedly connected to one side of the piston plate 51. The threaded sleeve 52 is slidably and sealingly confined within the part housing 1. A matching transmission screw 53 is threadedly connected to the threaded sleeve 52. The transmission screw 53 is rotatably connected to the part housing 1 via a rotating seat. A driven bevel gear B54 is fixedly disposed at one end of the transmission screw 53; and the driven bevel gear B54 meshes with a driven bevel gear A39 on the transmission screw shaft 32. Both driven bevel gears B54 mesh with the driving bevel gear 45.

[0065] In this technical solution, when the shear clamp 41 is pressed to drive the arc tooth plate 42 to mesh with the transmission gear shaft 43, the transmission gear shaft 43 drives the transmission screw shaft 32 to mesh and drive, while indirectly driving the transmission screw 53 to rotate. This causes the threaded sleeve 52 connected to the external thread of the transmission screw 53 to push and pull the piston plate 51 to draw gas from the sealed cavity, firmly adsorbing and fixing the transparent organic glass sealing cover 2 to the outside of the part housing 1.

[0066] Working principle: When it is necessary to clamp and install the biochip, first manually press the shear clamp 41. At this time, the shear clamp 41 meshes with the transmission gear shaft 43 through the arc tooth plate 42, and drives the transmission screw shaft 32 to rotate through the active bevel gear 45 and the driven bevel gear A39, pushing the stored support sleeve 33 to move upward to the limit.

[0067] As the supporting sleeve 33 moves upward, the limiting grooves 37 on the outer side of the multiple plastic clamping plates 36 slide with the limiting protrusions 38, causing the plastic clamping plates 36 to expand outward during the upward movement. At the same time, the upward movement of the supporting sleeve 33 also drives the side wall clamping plates 34 to move upward, so that the meshing teeth 35 fixedly connected to the outside of the side wall clamping plates 34 mesh with the meshing tooth blocks 11 fixedly installed on the inner wall of the part housing 1, thereby unfolding the closed side wall clamping plates 34 outward.

[0068] When the transmission screw shaft 32 rotates, it drives the transmission screw 53 to rotate through the driven bevel gear A39 and the driven bevel gear B54, and pushes the threaded sleeve 52, which is limited to the external threaded connection of the transmission screw 53, outward. This pushes the piston plate 51, which is fixedly connected to one end of the threaded sleeve 52, out of the suction chamber opened in the part housing 1. The gas in the chamber is then filled into the sealed cavity formed by the part housing 1 and the transparent plexiglass sealing cover 2 through the air hole connected to the part housing 1. This pushes open the transparent plexiglass sealing cover 2, which is sealed on the outside of the part housing 1.

[0069] Then, the biochip to be packaged is inserted into the support sleeve 33 for clamping and limiting. After the transparent plexiglass sealing cover 2 is sleeved on, the shear clamp 41 is released. At this time, the compressed reset device 44 resets, which drives the opened shear clamp 41 to reset. The clamping component 3 with limiting lifting moves down to the limiting position. The side wall clamp 34 and plastic clamp 36 in the clamping component 3 are limited and retracted, firmly clamping and limiting the biochip placed in the support sleeve 33. At the same time, the transmission screw 53 in the transmission suction component 5 rotates in the opposite direction to limit and pull the exhaust outward piston plate 51 inward. The piston plate 51 draws part of the gas in the sealed cavity formed by the sealing sleeve of the transparent plexiglass sealing cover 2 and the part housing 1 into the suction chamber, firmly adsorbing and limiting the transparent plexiglass sealing cover 2, thereby clamping, protecting and fixing the packaged biochip.

[0070] A method of using a biochip packaging structure includes the following steps:

[0071] S1. When clamping and installing the biochip, first manually press the shear clamp 41. The shear clamp 41 is driven by the meshing of the arc tooth plate 42 and the transmission tooth shaft 43. The transmission screw shaft 32 is rotated by the active bevel gear 45 and the driven bevel gear A39, which pushes the storage support sleeve 33 to move upward to the limit.

[0072] S2. While the supporting sleeve 33 moves upward, the plastic clamp 36 slides with the limiting protrusion 38 fixedly installed on the inner wall of the part housing 1, so that the plastic clamp 36 expands outward during the upward movement, and the side wall clamp 34 engages with the meshing tooth block 11 fixedly installed on the inner wall of the part housing 1 through the meshing tooth 35, so as to unfold the closed side wall clamp 34 outward.

[0073] S3. At this time, the transmission screw shaft 32 drives the transmission screw 53 to rotate through the driven bevel gear A39 and the driven bevel gear B54, which pushes the threaded sleeve 52, which is limited to the threaded connection outside the transmission screw 53, outward, thereby pushing the piston plate 51, which is fixedly connected to one end of the threaded sleeve 52, out of the suction chamber opened in the part housing 1. The gas in the chamber is filled into the sealed cavity formed by the part housing 1 and the transparent organic glass sealing cover 2 through the air hole connected to the part housing 1, and the transparent organic glass sealing cover 2 is opened.

[0074] S4. Finally, insert the biochip to be packaged into the support sleeve 33 for clamping and limiting. After the transparent plexiglass sealing cover 2 is put on, release the shear clamp 41 and the compression limiting reset device 44 is reset, thereby driving the clamping component 3 to firmly clamp and limit the placed biochip, and causing the transmission suction component 5 to suction the sealed cavity, firmly adsorbing and fixing the transparent plexiglass sealing cover 2.

[0075] S5. After the biochip is packaged, manually press the shear clamp 41 to move the supporting sleeve 33 upward while simultaneously causing the two side wall clamps 34 to flip outward. At the same time, the two plastic clamps 36 expand outward during the upward movement, thus removing the clamping limit on the biochip and making it easy and quick to remove the packaged biochip.

[0076] This invention utilizes a manually pressed opening and closing assembly to simultaneously adjust the height of the clamping component, causing multiple clamping plates within the clamping component to open and close, thereby clamping and securing the biochip. This improves the device's clamping and protection of the biochip and facilitates subsequent removal of the biochip, enhancing the safety and protection of the biochip during encapsulation. The lifting and lowering operation of the clamping component causes the limiting protrusions within the component's housing to compress and retract the plastic clamping plates, thus clamping the placed biochip. Furthermore, the side wall clamping plates, through the meshing action of the meshing teeth and teeth blocks, further clamp and limit the placed biochip, thereby improving the safety and protection of the encapsulated biochip. Simultaneously, by using the opening and closing assembly to lift and lower the clamping component to hold the biochip, the device can also drive the suction assembly to evacuate gas from the sealed cavity, achieving both rapid and safe use of the biochip and optimizing the flexibility of the encapsulation operation.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

At this time, the shear clamp (41) meshes with the transmission gear shaft (43) through the arc tooth plate (42), and drives the transmission screw shaft (32) to rotate through the active bevel gear (45) and the driven bevel gear A (39), pushing the stored support sleeve (33) to move upward to the limit. When the transmission screw shaft (32) rotates, it drives the transmission screw (53) to rotate through the driven bevel gear A (39) and driven bevel gear B (54), and pushes the threaded sleeve (52) that is limited to the external threaded connection of the transmission screw (53) outward, thereby pushing the piston plate (51) that is fixedly connected to one end of the threaded sleeve (52) out of the suction chamber opened in the housing (1) of the part.

2. The biochip package structure of claim 1, wherein: The inner sides of the part housing (1) are fixedly provided with meshing tooth blocks (11), and the outer side of the part housing (1) is fixedly provided with a docking sleeve (12). The docking sleeve (12) is embedded with a sealing ring, and the docking sleeve (12) is sleeved on the outside of the transparent organic glass sealing cover (2).

3. The biochip package structure of claim 2, wherein: Another shear clamp (41) has a fan-shaped reset device (44) fixedly installed on one side. The reset device (44) consists of an arc-shaped pressure rod, an arc-shaped pressure sleeve and a compression spring. The other end of the reset device (44) is fixedly connected to the inside of the part housing (1).

4. The biochip package structure of claim 3, wherein: The piston plate (51) has a suction chamfer on one side. The transmission screw (53) is rotatably connected to the inside of the part housing (1). The driven bevel gear B (54) on the transmission screw (53) meshes with the driven bevel gear A (39) on the transmission screw shaft (32).

5. The method of using a biochip package structure of claim 4, wherein, Includes the following steps: S1. When clamping and installing the biochip, first manually press the shear clamp (41). The shear clamp (41) drives the transmission gear shaft (43) to mesh and rotate through the arc tooth plate (42). Through the active bevel gear (45) and the driven bevel gear A (39), the transmission screw shaft (32) rotates, pushing the storage support sleeve (33) to move upward to the limit. S2. While the supporting sleeve (33) moves upward, the plastic clamp (36) slides with the limiting protrusion (38), so that the plastic clamp (36) expands outward during the upward movement, and the side wall clamp (34) is driven by the meshing tooth (35) and the meshing tooth block (11) to unfold the closed side wall clamp (34). S3. At this time, the transmission screw shaft (32) drives the transmission screw (53) to rotate through the driven bevel gear A (39) and the driven bevel gear B (54), which pushes the screw sleeve (52) that is limited to the threaded connection outside the transmission screw (53) outward, so that the piston plate (51) slides out the gas in the suction chamber opened in the part housing (1), and fills the gas in the chamber into the sealed cavity formed by the part housing (1) and the transparent organic glass sealing cover (2) through the air hole connected to the part housing (1), and pushes open the transparent organic glass sealing cover (2) that is fitted together. S4. Insert the biochip to be packaged into the support sleeve (33) for clamping and limiting. After the transparent organic glass sealing cover (2) is put on, release the shear clamp (41) and the compression limiting reset device (44) is reset, thereby driving the clamping component (3) to firmly clamp and limit the placed biochip, and causing the transmission suction component (5) to suction the sealed cavity, firmly adsorbing and limiting the transparent organic glass sealing cover (2) for fixing. S5. After the biochip is packaged, manually press the shear clamp (41) to move the support sleeve (33) upward while driving the two side wall clamps (34) to flip outward. At the same time, the two plastic clamps (36) expand outward during the upward movement, canceling the clamping limit on the biochip, making it easy and quick to take out the packaged biochip.
