Description

Technical Field

[0001] The utility model relates to the technical field of material transmission, in particular to a transfer window device and material transmission equipment. Background Art

[0002] In material transfer scenarios, transfer rails are often used between two pieces of equipment to transfer materials. Furthermore, many material transfer applications require air isolation between the two pieces of equipment, preventing air from flowing from one piece of equipment to the other. This requires a sealed cascade rail between the two pieces of equipment, as well as a hermetically sealed transfer window between the two pieces of equipment. The second sealed door on the left side of the transfer window must be prevented from opening simultaneously.

[0003] For example, in WGS library construction, the required laboratory process includes the following steps: enzyme digestion → fragment selection → adapter ligation → ligation product purification → PCR amplification → PCR product purification → quantification → pooling → circularization → digestion → purification → quantification → iso-DNB preparation → quantification. Aerosols are generated during the PCR amplification step. To prevent aerosol contamination of pre-amplification materials, the aforementioned process needs to be divided into two areas: the pre-library construction area and the post-library construction area. The pre-PCR amplification process is carried out in the pre-library construction area, and the post-amplification process is carried out in the post-library construction area. The post-library construction area needs to be sealed and maintained at negative pressure during the experiment.

[0004] In existing technologies, most front and back areas are separated into two rooms, separated by walls. This not only requires a cross-room layout, which occupies a large area, but also requires a floor-to-ceiling door between the front and back areas, which is costly and inconvenient to integrate.

[0041] like Figure 1 and Figure 2 As shown, the present invention discloses a transfer window device 10 that can be installed between two devices to establish a transfer channel between the two devices. After a material 20 is tested in one device, it can be removed. The material 20 removed from the device can be moved to another device through the transfer window device 10 for testing in the other device. To facilitate the description of the structure of the transfer window device 10, the two devices are defined as a first device 30 and a second device 40.

[0042] like Figures 3 to 11As shown, the transfer window device 10 includes a transmission mechanism 100 and a transfer window module 200. The two ends of the transmission mechanism 100 can be detachably connected to a first device 30 and a second device 40, respectively. The first device 30 has a first space 31 for testing the material 20 formed therein, and a first inlet and outlet 32 ​​for the material 20 to enter and exit the first space 31 is provided on the first device 30. The second device 40 has a second space 41 for testing the material 20 formed therein, and a second inlet and outlet 42 for the material 20 to enter and exit the second space 41 is provided on the second device 40.

[0043] The transfer window module 200 includes a transfer window 210, a first sealing door 220, and a second sealing door 230. The transfer window 210 is sealingly mounted on the transmission mechanism 100. The transfer window 210 has a first window on the side facing the first entrance 32, and a second window on the side facing the second entrance 42. The first sealing door 220 is movably connected to the first window and can seal the first entrance 32. The second sealing door 230 is movably connected to the second window and can seal the second entrance 42.

[0044] In other words, the conveying mechanism 100 passes through the first and second entrances and exits 32, 42 and through the passbox module 200, thereby sequentially connecting the first device 30, the passbox module 200, and the second device 40. The material 20 can be transferred between the first device 30, the passbox module 210, and the second device 40 via the conveying mechanism 100. It should be noted that the first device 30, the passbox module 200, and the second device 40 can be arranged collinearly, in which case the conveying mechanism 100 is linear; alternatively, the first device 30, the passbox module 200, and the second device 40 can be arranged in a triangular shape, in which case the conveying mechanism 100 is in a broken line shape, such as an L-shape; of course, the conveying mechanism 100 can also be in a curved shape, as long as it does not affect the transmission of the material 20.

[0045] It is defined that the first device 30 is upstream of the second device 40, and the material 20 is first tested in the first device 30. At this time, the first sealing door 220 is in a position to seal the first inlet and outlet 32 ​​and the first window, and at the same time, the first sealing door 220 is in a position to seal the second inlet and outlet 42 and the second window. At this time, the first space 31 and the second space 41 are both in a sealed state, and the gases in the first space 31 and the second space 41 will not leak out and cannot be exchanged.

[0046] After the material 20 completes the experiment in the first device 30, the material 20 moves to a position close to the first sealing door 220. When the first sealing door 220 moves to a position where the first inlet and outlet 32 ​​and the first window are opened, the material 20 in the first space 31 can enter the transfer window 210 through the first inlet and outlet 32 ​​and the first window; then, the first sealing door 220 moves again to a position where the first inlet and outlet 32 ​​are sealed, thereby isolating the material 20 from outside the first space 31, and the first space 31 is restored to a sealed state again; then, the material 20 moves in the transfer window 210 to a position close to the second sealing door 230. The second sealing door 230 moves to a position where the second inlet and outlet 42 and the second window are opened, and the material 20 in the transfer window 210 can enter the second device 40 through the second inlet and outlet 42 and the second window; finally, the second sealing door 230 moves again to a position where the second inlet and outlet 42 are sealed, thereby isolating the material 20 from outside the second space 41, and the second space 41 is restored to a sealed state again.

[0047] The transfer window device 10 utilizes a transfer mechanism 100 to quickly assemble and disassemble with the first device 30 and the second device 40, allowing it to be reused between different devices, expanding its scope of use. Furthermore, by alternately opening and closing the first and second sealing doors 220 and 230, the transfer window device 10 allows materials 20 to be transferred between adjacent devices in different environments. Furthermore, the transfer window device 10 has a compact structure, occupies a small area, is easy to deploy, and has low manufacturing costs.

[0048] Continue to refer to Figures 3 to 7 As shown, in some embodiments, the conveying mechanism 100 includes a slide rail 110 and a material rack 120. The end of the slide rail 110 can extend into the first device 30 or the second device 40, thereby achieving docking between the conveying mechanism 100 and the first device 30 and the second device 40. The material rack 120 is slidably connected to the slide rail 110 and is used to carry the material 20. Specifically, the slide rail 110 is provided with a slide groove, and the bottom of the material rack 120 is provided with a slider, and the slide rail 110 is slidably connected to the slide groove.

[0049] In order to achieve sealing of the slide rail 110, thereby preventing the gas in the first device 30 and the second device 40 from leaking from the slide groove position, in some embodiments, the slide rail 110 is coated with a sealing layer 150. In one embodiment, the sealing layer 150 includes a sealing strip laid on the bottom of the slide groove, and optionally, the sealing strip is a silicone strip. In another alternative embodiment, the sealing layer 150 includes a sealing layer wrapped around the outer wall of the slide rail 110, and optionally, the sealing layer is a silicone layer. Of course, in other embodiments, the stainless steel belt can be tightly attached to the slide rail 110 by magnetic attraction to achieve full sealing.

[0050] In order to improve the convenience of disassembling and assembling the slide rail 110 and the first device 30 and the second device 40, continue to refer to Figure 3 As shown, a first mounting seat 130 and a second mounting seat 140 are respectively provided at both ends of the slide rail 110. The first mounting seat 130 can be detachably connected to a first assembly seat provided in the first device 30, and the second mounting seat 140 can be detachably connected to a second assembly seat provided in the second device 40. The detachable connection method includes but is not limited to a screw connection, a snap connection, a magnetic connection, etc.

[0051] In one embodiment, the first mounting seat 130 and the second mounting seat 140 have the same structure, and the first assembly seat and the second assembly seat have the same structure, so that the first mounting seat 130 can be adapted to the second assembly seat, and the second mounting seat 140 can be adapted to the first assembly seat, so that there is no need to adjust the direction when installing the transmission mechanism 100.

[0052] It should be noted that the first mounting seat 130 and the first assembly seat are provided with a first positioning structure for facilitating quick positioning, and the first positioning structure includes but is not limited to a combination of a positioning groove and a positioning block. The first mounting seat 130, the second mounting seat 140, the first assembly seat and the second assembly seat can be designed as standardized independent modules, and any two devices that need to use the transfer window device 10 can be installed with the first assembly seat and the second assembly seat, so that the transmission mechanism 100 can be easily disassembled and reused, which is conducive to reducing design costs. And if Figure 6 and Figure 7 As shown, the slide rail 110 can be extended to any length and assembled in modular configurations to meet different length requirements without requiring repeated design. To facilitate installation of the slide rail 110, the first device 30 and the second device 40 are maintained at the same horizontal position, i.e., the first assembly seat and the second assembly seat are located at the same horizontal position.

[0053] Compared with the existing solutions of mechanical arm transmission, robot transmission, conveyor belt transmission, etc., the transmission mechanism 100 provided by the utility model adopts the transmission method of the slide rail 110, which can realize the rapid transfer of materials 20 at low cost and high efficiency. The modular and standardized design of the mounting seat and the assembly seat are used to realize the grafting and assembly of the transfer window device 10 between any two devices, which can achieve rapid assembly and low-cost design. The slide rail 110 adopts a sealed design to ensure the sealing of the space inside the equipment and avoid the leakage of gas inside the equipment.

[0054] Continue to refer to Figure 8 As shown, in some embodiments, the transfer window 210 is in a cubic shape, and a avoidance groove 211 is provided at the bottom of the transfer window 210 for the slide rail 110 to pass through, and the first window and the second window are both provided above the avoidance groove 211.

[0055] In some embodiments, the first sealing door 220 is slidably disposed at the first window along a first direction and is capable of sliding to a first sealing position that closes and seals the first window and the first access port 32, and to a first open position that opens the first access port 32 and the first window. The second sealing door 230 is disposed at the second window along a second direction and is capable of sliding to a second sealing position that closes and seals the second window and the second access port 42, and to a second open position that opens the second access port 42 and the second window. Of course, in other embodiments, the first sealing door 220 may also be rotatably mounted at the first window, and the second sealing door 230 may also be rotatably mounted at the second window.

[0056] Optionally, the first sealing door 220 slides in a direction that is at a certain angle to the vertical direction, and the second sealing door 230 slides in a direction that is at a certain angle to the vertical direction.

[0057] In order to achieve precise movement of the first sealing door 220, the transfer window module 200 also includes a first driving mechanism 250 and a first guide mechanism 240. The first guide mechanism 240 extends along the first direction, and the first sealing door 220 is slidingly connected to the first guide mechanism 240. The first driving mechanism 250 is used to drive the first sealing door 220 to move along the first guide mechanism 240, so that the first sealing door 220 can move to the first sealing position that seals the first window and the first inlet and outlet 32.

[0058] The first guide mechanism 240 is a first inclined guide rail, which is arranged gradually closer to the first device 30 from top to bottom. In this way, the first sealing door 220 is gradually pressed against the surface of the first device 30 where the first inlet and outlet 32 ​​are formed during the closing process, thereby improving the sealing performance of the first inlet and outlet 32.

[0059] like Figure 11 As shown, the first driving mechanism 250 includes a first motor 251, a first gear 252 and a first rack 253. The motor shaft of the first motor 251 is connected to the first gear 252. The first rack 253 extends along the first direction and is arranged on the first sealing door 220. The first gear 252 and the first rack 253 are engaged.

[0060] In one embodiment, the first drive mechanism 250 and the first sealing door 220 are disposed on two adjacent side walls of the transfer window 210. The first sealing door 220 includes a first door body 221 and a first flange 222. A first rack 253 is disposed on the first flange 222. The first flange 222 is slidably connected to the first inclined guide rail. The first door body 221 is used to open and close the first access port 32 and the first window. Of course, in other embodiments, the first drive mechanism 250 may also be another mechanism capable of outputting linear motion, such as a combination of a motor and a lead screw nut, a linear motor, a pneumatic cylinder, etc.

[0061] In order to improve the sealing performance, Figure 10 As shown, the first sealing door 220 further includes a first sealing strip 223 provided on the side of the first door body 221 facing the first device 30. The first sealing strip 223 is used to seal between the first door body 221 and the first device 30. When the first sealing door 220 is pressed against the surface of the first device 30 where the first inlet and outlet 32 ​​is formed, the first sealing strip 223 is squeezed and deformed, and fills the edge of the first inlet and outlet 32, thereby improving the sealing performance of the first inlet and outlet 32.

[0062] In one embodiment, the first sealing strip 223 is a slot-type sealing strip. This slot-type sealing strip comprises a snap-fitting portion and a sealing portion. The first door body 221 is provided with a snap-fitting slot that engages with the snap-fitting portion. The sealing portion is hollow and easily deforms under external forces, thereby improving the seal. Of course, in other embodiments, the first sealing strip 223 may also have other shapes. In one embodiment, the first sealing strip 223 is annular and shaped to match the opening of the first inlet / outlet 32.

[0063] Continue to refer to Figure 10 As shown, the first sealing door 220 further includes a second sealing strip 224 provided on the circumference of the first door body 221. The second sealing strip 224 is used to seal between the outer wall surface of the first door body 221 and the inner wall surface of the first window. When the first sealing door 220 closes the first window, the second sealing strip 224 is squeezed and deformed, and fills the space between the outer wall surface of the first door body 221 and the inner wall surface of the first window, thereby improving the sealing between the first window and the first door body 221.

[0064] In one embodiment, the second sealing strip 224 is a D-shaped sealing strip. The D-shaped sealing strip has a hollow structure and is easily deformed under external forces, which helps improve the sealing performance. Of course, in other embodiments, the second sealing strip 224 can also have other shapes.

[0065] Continue to refer to Figure 10 As shown, the first sealed door 220 further includes a third sealing strip 225 disposed on the side of the first door body 221 facing away from the first device 30. A first oblique guide support plate 212 is disposed within the transfer window 210 for supporting and guiding the first door body 221. The third sealing strip 225 is disposed between the first door body 221 and the first oblique guide support plate 212.

[0066] In one embodiment, the third sealing strip 225 is a T-shaped sealing strip, the horizontal portion of which is fixed to the first oblique guide support plate 212 , and the vertical portion of which abuts against the surface of the first door body 221 away from the first side plate.

[0067] The opening and closing process of the first sealing door 220 is as follows:

[0068] Opening process: The first motor 251 drives the first rack 253 to move through the first gear 252, and the first rack 253 drives the first sealing door 220 to move along the first inclined guide rail in an oblique upward direction away from the first device 30. During the movement, the first sealing strip 223 provided between the first sealing door 220 and the surface of the first device 30 forming the first inlet and outlet 32 ​​gradually recovers from the compressed state until a gap is completely formed between the first sealing door 220 and the first device 30 for the material 20 to pass through. At this point, the opening action of the first sealing door 220 is completed.

[0069] Closing process: The first motor 251 drives the first rack 253 in reverse through the first gear 252, and the first rack 253 drives the first sealing door 220 to move along the first inclined guide rail in an oblique downward direction close to the first device 30. During the movement, the first sealing strip 223 provided between the first sealing door 220 and the surface of the first device 30 forming the first inlet and outlet 32 ​​is gradually compressed and deformed from the expanded state until the entire first sealing strip 223 is completely compressed and sealed in place against the surface of the first device 30 forming the first inlet and outlet 32. At this point, the closing action of the first sealing door 220 is completed.

[0070] In order to achieve precise movement of the second sealing door 230, the transfer window module 200 also includes a second driving mechanism 270 and a second guide mechanism 260. The second guide mechanism 260 is extended along the second direction, and the second sealing door 230 is slidingly connected to the second guide mechanism 260. The second driving mechanism 270 is used to drive the second sealing door 230 to move along the second guide mechanism 260, so that the second sealing door 230 can move to the second sealing position that seals the second window and the second inlet and outlet 42.

[0071] The second guide mechanism 260 is a second inclined guide rail, which is arranged gradually closer to the second device 40 from top to bottom. In this way, the second sealing door 230 is gradually pressed against the surface of the second device 40 where the second inlet and outlet 42 are formed during the closing process, thereby improving the sealing performance of the second inlet and outlet 42.

[0072] The second driving mechanism 270 includes a second motor 271 , a second gear and a second rack 272 . The motor shaft of the second motor 271 is connected to the second gear. The second rack 272 extends along the second direction and is arranged on the second sealing door 230 . The second gear and the second rack 272 are meshed.

[0073] In one embodiment, the second drive mechanism 270 and the second sealing door 230 are disposed on two adjacent side walls of the transfer window 210. The second sealing door 230 includes a second door body 231 and a second flange 232. A second rack 272 is disposed on the second flange 232. The second flange 232 is slidably connected to the second inclined guide rail. The second door body 231 is used to open and close the second access port 42 and the second window. Of course, in other embodiments, the second drive mechanism 270 can also be other mechanisms capable of outputting linear motion, such as a combination of a motor and a lead screw nut, a linear motor, a pneumatic cylinder, etc.

[0074] To improve sealing, the second sealing door 230 further includes a fourth sealing strip disposed on the side of the second door body 231 facing the second device 40. The fourth sealing strip is used to seal between the second door body 231 and the second device 40. When the second sealing door 230 is pressed against the surface of the second device 40 where the second inlet and outlet 42 is formed, the fourth sealing strip is squeezed and deformed, and fills the edge of the second inlet and outlet 42, thereby improving the sealing of the second inlet and outlet 42.

[0075] In one embodiment, the fourth sealing strip is a slot-type sealing strip. The slot-type sealing strip includes a snap-fitting portion and a sealing portion. The second door body 231 is provided with a snap-fitting slot that engages with the snap-fitting portion. The sealing portion is hollow and easily deforms under external forces, thereby improving the seal. Of course, in other embodiments, the fourth sealing strip can also have other shapes. In one embodiment, the fourth sealing strip is annular and shaped to match the opening shape of the second inlet / outlet 42.

[0076] The second sealing door 230 further includes a fifth sealing strip disposed circumferentially around the second door body 231. The fifth sealing strip is configured to seal between the outer wall of the second door body 231 and the inner wall of the second window. When the second sealing door 230 closes the second window, the fifth sealing strip is squeezed and deformed, filling the space between the outer wall of the second door body 231 and the inner wall of the second window, thereby improving the sealing between the second window and the second door body 231.

[0077] In one embodiment, the fifth sealing strip is a D-shaped sealing strip. The D-shaped sealing strip has a D-shaped cross-section and a hollow structure that easily deforms under external forces, thereby improving the sealing performance. Of course, in other embodiments, the fifth sealing strip may also have other shapes.

[0078] The second sealed door 230 includes a second door body 231 and a sixth sealing strip disposed on the side of the second door body 231 facing away from the second device 40. A second oblique guide support plate is disposed within the transfer window 210 for supporting and guiding the second door body 231. The sixth sealing strip is disposed between the second door body 231 and the second oblique guide support plate.

[0079] In one embodiment, the sixth sealing strip is a T-shaped sealing strip, the horizontal portion of the T-shaped sealing strip is fixed to the second oblique guide support plate, and the vertical portion abuts against the surface of the second door body 231 facing away from the second side plate.

[0080] The opening and closing process of the second sealing door 230 is as follows:

[0081] Opening process: The second motor 271 drives the second rack 272 to move through the second gear, and the second rack 272 drives the second sealing door 230 to move along the second inclined guide rail in an oblique upward direction away from the second device 40. During the movement, the fourth sealing strip provided between the second sealing door 230 and the surface of the second device 40 forming the second inlet and outlet 42 gradually recovers from the compressed state until a gap is completely formed between the second sealing door 230 and the second device 40 for the material 20 to pass through. At this point, the opening action of the second sealing door 230 is completed.

[0082] Closing process: the second motor 271 drives the second rack 272 in reverse through the second gear, and the second rack 272 drives the second sealing door 230 to move along the second inclined guide rail in an oblique downward direction close to the second device 40. During the movement, the fourth sealing strip provided between the second sealing door 230 and the surface of the second device 40 forming the second inlet and outlet 42 is gradually compressed and deformed from the expanded state until the entire fourth sealing strip is completely compressed and sealed into place against the surface of the second device 40 forming the second inlet and outlet 42. At this point, the closing action of the second sealing door 230 is completed.

[0083] like Figure 1 and Figure 2 As shown, the present invention further provides a material transfer device, which includes at least one first device 30, at least one second device 40, and the aforementioned transfer window device 10. By using the transfer window device 10, the material transfer device can block the gas transfer between the first device 30 and the second device 40, so that the gases in the two devices do not mix, thereby enabling the material 20 to be transferred between the two adjacent devices in different environments.

[0084] like Figures 3 to 5 As shown, the material conveying equipment is in the following three states during the process of conveying the material 20: 1. The material rack 120 for carrying the conveyed material 20 is on the left side of the transfer window 210, the first sealing door 220 is open, and the second sealing door 230 is closed; 2. The material rack 120 is inside the transfer window 210, the first sealing door 220 is closed, and the second sealing door 230 is closed; 3. The material rack 120 is on the right side of the transfer window 210, the first sealing door 220 is closed, and the second sealing door 230 is open.

[0085] It should be noted that the number of first devices 30 can be set to one or more according to needs, and the number of second devices 40 can be set to one or more according to needs. When at least one of the first devices 30 and the second devices 40 is provided in plurality, the adjacent first devices 30 and the second devices 40 can be connected through a transfer window device 10, thereby realizing a multi-level connection of the first devices 30 and the second devices 40.
