Description

Technical Field

[0001] This application relates to the field of experimental equipment technology, specifically to a container sealing device, a container sealing equipment, and a method for testing sealing performance. Background Technology

[0002] Multiple reaction vessels are typically sealed simultaneously using container sealing devices, enabling parallel reactions and synthesis experiments to be conducted within these vessels. This facilitates the exploration of reaction routes, optimization of conditions, and investigation of efficient synthesis in synthetic chemistry research. Container sealing devices are suitable for modern reaction synthesis research that demands strict requirements for system airtightness, wide temperature control range, high temperature control accuracy, and good repeatability.

[0003] In related technologies, reaction vessels are typically sealed manually by tightening the fastening screws on the sealing device. When loosening the fastening screws to unseal the reaction vessel, the screws are easily lost, affecting subsequent sealing applications and resulting in poor sealing efficiency. Furthermore, this also hinders automated integration. Summary of the Invention

[0004] The purpose of this application is to provide a container sealing device, container sealing equipment, and a sealing performance testing method, which solves the problems of low sealing efficiency and low degree of automation integration of the container sealing device.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] In a first aspect, this application provides a container sealing device, comprising: a base having a limiting portion for fixing a container; a cover plate having a first mounting hole; a sealing element connected to a surface of the cover plate, the sealing element having a second mounting hole communicating with the first mounting hole, the sealing element for closing the opening of the container when the cover plate is placed on the base; and a sleeve assembly including a sleeve, a fastener, and an elastic element, the sleeve being connected to the surface of the cover plate opposite to the sealing element, the sleeve communicating with the first mounting hole, at least a portion of the fastener and the elastic element being housed within the sleeve, one end of the fastener near the base passing through the first mounting hole and the second mounting hole and being detachably connected to the base, one end of the fastener away from the base having an abutment portion, the elastic element being sleeved on the outer periphery of the fastener, and both ends of the elastic element abutting against the abutment portion and the surface of the cover plate opposite to the sealing element, respectively.

[0078] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0079] This application provides a container sealing device 100. Please refer to [link / reference]. Figure 1 The container sealing device 100 includes a base 10 and a cover plate 20. The base 10 is provided with a limiting part 13, which is used to fix the container 50. The cover plate 20 is arranged opposite to the base 10. When the cover plate 20 is connected to the base 10, the cover plate 20 seals the container 50 and cooperates with the base 10 to fix the container 50.

[0080] Container 50 has an opening at one end and can be used to hold reagents. Container 50 can be, but is not limited to, test tubes and centrifuge tubes. Optionally, container 50 has a sealed bottom and an open top. Base 10 is located on the bottom side of container 50 away from the top and is used to support and fix container 50. Cover 20 is located on the side of container 50 with the opening and is used to seal the opening of container 50.

[0081] Please see Figure 2 , Figure 3 and Figure 4The container sealing device 100 also includes a sleeve assembly 40, which includes a sleeve 41, a fastener 42, and an elastic element 43. The sleeve 41 is located on one side of the cover plate 20 and is connected to the surface of the cover plate 20. When the cover plate 20 covers the base 10, the sleeve 41 is located on the side of the cover plate 20 facing away from the base 10. The sleeve 41 encloses a channel in which the fastener 42 and the elastic element 43 are accommodated. Optionally, the sleeve 41 extends from the base 10 toward the cover plate 20. The end of the fastener 42 away from the base 10 is accommodated in the sleeve 41, and the end near the base 10 is used for detachable connection with the base 10, so that the cover plate 20 and the base 10 are connected and fixed by the fastener 42. The elastic element 43 is entirely accommodated in the sleeve 41 and is sleeved on the outer periphery of the fastener 42, and is used to generate elastic force to cooperate with the fastener 42 and the base 10 during disassembly and installation.

[0082] When the container sealing device 100 seals the container 50, the cover plate 20 is placed opposite the base 10, and the fastener 42 is connected to the base 10, so that the cover plate 20 is clamped to the base 10 under the action of the fastener 42, thereby achieving the sealing of the container 50 by the cover plate 20.

[0083] The fastener 42 is at least partially housed within the channel enclosed by the sleeve 41. One end of the fastener 42 near the base 10 passes through the cover plate 20 and is detachably connected to the base 10, so that the cover plate 20 and the base 10 are connected and fixed by the fastener 42. The other end of the fastener 42 away from the base 10 is housed within the channel enclosed by the sleeve 41 and has an abutment portion 421. The abutment portion 421 protrudes from the outer peripheral surface of the fastener 42 body, that is, the orthographic projection area of ​​the fastener 42 body on the abutment portion 421 is smaller than the surface area of ​​the abutment portion 421, which is beneficial for achieving the limiting function.

[0084] The elastic element 43 is completely housed within the channel enclosed by the sleeve 41. The elastic element 43 is sleeved around the outer periphery of the fastener 42. One end of the elastic element 43 abuts against the surface of the abutment portion 421 facing the base 10, and the other end abuts against the surface of the cover plate 20 facing the sleeve 41, thus the elastic element 43 is sandwiched between the abutment portion 421 and the cover plate 20. When the fastener 42 moves closer to the base 10, the abutment portion 421 moves closer to the base 10, the elastic element 43 is compressed, and it pushes the cover plate 20 closer to the base 10, causing the cover plate 20 to clamp against the base 10 under the action of the fastener 42, thereby achieving a seal between the cover plate 20 and the container 50.

[0085] At least some of the fasteners 42 and all of the elastic elements 43 are housed within the channel enclosed by the sleeve 41, so that the sleeve 41 can limit the fasteners 42 and elastic elements 43, which helps to improve the stability of the position of the fasteners 42 and elastic elements 43 during use.

[0086] Fastener 42 and base 10 are connected in a mating manner. Fastener 42 can reciprocate within the channel enclosed by sleeve 41 to change the tightness of the mating connection between fastener 42 and base 10, thereby changing the tightness of the mating connection between cover plate 20 and base 10. Fastener 42 can be moved manually or by an automated device.

[0087] Optionally, when the fastener 42 moves from the cover plate 20 toward the base 10, the connection between the fastener 42 and the base 10 becomes tighter, the elastic element 43 is compressed, and the cover plate 20 moves toward the base 10 under the action of the fastener 42. The cover plate 20 is connected to the base 10 through the fastener 42, thus sealing the container 50. When the fastener 42 moves from the base 10 toward the cover plate 20, the connection between the fastener 42 and the base 10 becomes loose, the elastic element 43 rebounds, and the elastic element 43 applies a spring force from the base 10 toward the cover plate 20 to the fastener 42, promoting the fastener 42 to quickly reset. When the connection between the fastener 42 and the base 10 is released, the cover plate 20 can be removed from the base 10, thus releasing the seal on the container 50.

[0088] The elastic element 43 is always housed within the channel enclosed by the sleeve 41, and when the fastener 42 reciprocates within the channel enclosed by the sleeve 41, both ends of the elastic element 43 always maintain contact with the cover plate 20 and the abutment portion 421.

[0089] Please see Figure 2 , Figure 4 , Figure 8 and Figure 9 The container sealing device 100 also includes a sealing element 30, which is connected to the surface of the cover plate 20 facing away from the sleeve 41, i.e., the sealing element 30 is disposed on the side of the cover plate 20 facing the base 10. When the container sealing device 100 seals the container 50, the cover plate 20 covers the base 10, the cover plate 20 moves toward the base 10, and the sealing element 30 contacts the container 50, covering and sealing the opening of the container 50.

[0090] The seal 30 is elastic and can deform under pressure to improve the sealing effect between the seal 30 and the opening of the container 50. The seal 30 can directly abut against the edge of the opening of the container 50, or when the seal 30 abuts against the open end of the container 50, the open end of the container 50 is partially embedded in the seal 30, so that the outer peripheral surface of the open end of the container 50 contacts the seal 30, thereby improving the sealing effect of the seal 30 on the container 50.

[0091] The cover plate 20 has a first mounting hole 21, and the seal 30 has a second mounting hole 31. The second mounting hole 31 communicates with the first mounting hole 21, and the channel enclosed by the sleeve 41 communicates with the first mounting hole 21, so that the channel enclosed by the sleeve 41, the first mounting hole 21, and the second mounting hole 31 are all connected. When the fastener 42 moves from the cover plate 20 toward the base 10, the end of the fastener 42 near the base 10 passes through the first mounting hole 21 and the second mounting hole 31, so that the end of the fastener 42 near the base 10 protrudes from the seal 30 and is detachably connected to the base 10.

[0092] There is a gap between the second mounting hole 31 and the opening of the container 50 to prevent the second mounting hole 31 from communicating with the container 50, thereby affecting the sealing effect of the seal 30 on the container 50.

[0093] The container sealing device 100 provided in this application includes a cover plate 20 and a base 10, which are detachably connected. The base 10 is provided with a limiting part 13 for fixing the container 50. A sealing element 30 is connected to the surface of the cover plate 20 facing the base 10, which is used to seal the container 50 to improve the sealing effect of the container 50. A sleeve assembly 40 is connected to the surface of the cover plate 20 facing away from the base 10. The sleeve assembly 40 includes a sleeve 41, a fastener 42, and an elastic element 43. The sleeve 41 is used to accommodate the fastener 42 and the elastic element 43, thereby limiting the position of the fastener 42 and the elastic element 43 and ensuring the stability of their positions. At the same time, it avoids the fastener 42 from tilting during the connection with the base 10, which would require multiple adjustments to the movement direction of the fastener 42 and could also easily cause the cover plate 20 to tilt during the fastening process with the base 10. This is beneficial to improving the sealing efficiency and sealing effect of the container sealing device 100 on the container 50.

[0094] When an automated device acts on the fastener 42 to seal the container sealing device 100, the structure of the fastener 42 housed within the sleeve 41 simplifies the identification of the action position by the automated device and ensures the stability of the fastener 42's position under the action of the automated device. Simultaneously, during the process of releasing the connection between the fastener 42 and the base 10, the elastic element 43 applies a spring force from the base 10 towards the cover plate 20 to the fastener 42, assisting in the release of the connection between the fastener 42 and the base 10, which helps improve the sealing and unsealing efficiency of the container sealing device 100 on the container 50. Furthermore, when the fastener 42 is released from the base 10, it is confined within the sleeve 41, eliminating the need for additional storage and preventing loss, thus improving sealing efficiency and facilitating automated integration.

[0095] In one implementation, please refer to Figure 8 , Figure 9 and Figure 10The sleeve 41 and the cover plate 20 are detachably connected, which helps to simplify the processing and forming of the sleeve 41 and the cover plate 20 and improve the processing yield of the sleeve 41 and the cover plate 20. At the same time, the number and position of the sleeve 41 can be adjusted appropriately according to actual needs to prevent the cover plate 20 from tilting during the fastening process with the base 10, thereby improving the sealing efficiency and sealing effect of the cover plate 20 and the base 10 on the container 50.

[0096] The sleeve 41 includes a sleeve body 411 and a fixing part 412. The fixing part 412 is connected to the outer peripheral surface of the sleeve body 411. The sleeve body 411 encloses a channel for accommodating the fastener 42 and the elastic member 43. The fixing part 412 protrudes from the outer peripheral surface of the sleeve body 411 and is detachably connected to the cover plate 20 to realize the detachable connection between the sleeve body 411 and the cover plate 20.

[0097] The fixing part 412 and the sleeve body 411 can be an integral structure or they can be different parts that are connected to each other. This application does not limit this.

[0098] Optionally, the fixing part 412 is connected to the end of the sleeve body 411 in the extending direction, so that one end of the sleeve body 411 is connected to the cover plate 20. In the extending direction of the sleeve body 411, the extending length of the fixing part 412 can be equal to the extending length of the sleeve body 411, which helps to increase the connection area between the fixing part 412 and the sleeve body 411, thereby increasing the stability of the connection between the sleeve body 411 and the cover plate 20 through the fixing part 412.

[0099] Optionally, the fixing part 412 also encloses a channel, and the channel of the fixing part 412 is provided with a threaded structure. The fixing part 412 and the cover plate 20 are connected by bolts. The bolts pass through the channel enclosed by the fixing part 412 and are connected to the threaded structure in the channel of the fixing part 412.

[0100] The number of fixing parts 412 can be multiple. Multiple fixing parts 412 are evenly spaced on the outer peripheral surface of the sleeve body 411 to improve the stability of the connection and fixation between the sleeve body 411 and the cover plate 20.

[0101] In one implementation, please refer to Figure 8 , Figure 9 and Figure 10 The cover plate 20 also includes a limiting cover 44, which is connected to the end of the sleeve 41 facing away from the cover plate 20. The limiting cover 44 has an operating hole 441, which is connected to the channel enclosed by the sleeve 41, and the operating hole 441 is opposite to the fastener 42. When the fastener 42 is moved, the fastening device 200 extends through the operating hole 441 into the sleeve 41 and contacts the fastener 42.

[0102] The size of the operating hole 441 is smaller than the size of the abutment portion 421, that is, the orthogonal projection area of ​​the operating hole 441 on the abutment portion 421 is smaller than the area of ​​the abutment portion 421, so that the end of the fastener 42 facing away from the base 10 is always contained within the channel enclosed by the sleeve 41, preventing the fastener 42 from being ejected when subjected to the elastic force of the elastic member 43, and ensuring the stability of the position of the fastener 42.

[0103] The limiting cover 44 and the sleeve 41 are detachably connected. When assembling the sleeve assembly 40, the fastener 42 and the elastic element 43 are first installed in the sleeve 41, and then the limiting cover 44 is connected to the end of the sleeve 41 facing away from the cover plate 20, so that the limiting cover 44 restricts the position of the fastener 42 and the elastic element 43.

[0104] Optionally, the limiting cover 44 also has a fixing hole, which is connected to the channel enclosed by the fixing hole and the fixing part 412, and the bolts in the fixing hole and the channel enclosed by the fixing part 412 are opposite each other. When the fixing part 412 is connected or disassembled with the cover plate 20 by the bolt, the fastening device 200 extends through the fixing hole into the channel enclosed by the fixing part 412 and contacts the bolt.

[0105] In one implementation, please refer to Figure 1 There are multiple sleeve assemblies 40, which are evenly distributed on the surface of the cover plate 20. Each sleeve assembly 40 has a fastener 42, so that the container sealing device 100 has multiple fasteners 42. The multiple fasteners 42 are evenly distributed and are detachably connected to the base 10, which helps to improve the stability of the connection between the cover plate 20 and the base 10 and prevents the cover plate 20 from tilting during the fastening process with the base 10.

[0106] Optionally, multiple sleeve assemblies 40 are arranged in an array on the surface of the cover plate 20, such as a 3×2 array, a 3×3 array, a 3×4 array, etc.

[0107] When multiple fasteners 42 move within the channel enclosed by the sleeve 41, multiple fastening devices 200 can be used simultaneously to act on multiple fasteners 42, so that multiple fasteners 42 move synchronously from the cover plate 20 toward the base 10 or multiple fasteners 42 move synchronously from the base 10 toward the cover plate 20; alternatively, a single fastening device 200 can be used to act on multiple fasteners 42 sequentially to achieve the connection and disassembly of multiple fasteners 42 with the base 10 in sequence.

[0108] In one implementation, please refer to Figure 4 and Figure 7 The base 10 has a fastening fitting 14, which is arranged opposite to the second mounting hole 31. That is, the channel enclosed by the sleeve 41, the first mounting hole 21, the second mounting hole 31 and the fastening fitting 14 are all arranged opposite to each other.

[0109] The end of the fastener 42 near the base 10 passes through the first mounting hole 21 and the second mounting hole 31 and is connected to the fastening fitting 14, so that the fastener 42 is detachably connected to the base 10, thereby realizing the detachable connection between the cover plate 20 and the base 10.

[0110] Optionally, the fastener 42 and the fastening mating part 14 are threaded together. The fastener 42 can be a screw, and the fastening mating part 14 can be a hole with a threaded structure on its inner wall; alternatively, the fastener 42 can have a hole with a threaded structure at one end near the base 10, and the fastening mating part 14 can be a screw.

[0111] Optionally, the inner wall of the first mounting hole 21 has a threaded structure, and the fastener 42 also engages with the inner wall of the first mounting hole 21, so that the fastener 42 is detachably connected to both the cover plate 20 and the base 10.

[0112] On the surface of the base 10 facing the cover 20, fastening fittings 14 and limiting portions 13 are spaced apart to prevent interference between the fasteners 42 and the receiving portion. Multiple fastening fittings 14 can be provided, with the number of fastening fittings 14 equal to the number of sleeve assemblies 40. Each fastening fitting 14 corresponds to one sleeve assembly 40, ensuring a one-to-one connection between the fastening fittings 14 and the fasteners 42. This improves the stability of the connection between the cover 20 and the base 10, thereby enhancing the sealing performance of the container sealing device 100 on the container 50.

[0113] In one implementation, please refer to Figure 1 , Figure 5 and Figure 8 The cover plate 20 has a first positioning member 22, which is located on the side of the cover plate 20 facing the base 10; the base 10 has a second positioning member 15, which is located on the side of the base 10 facing the cover plate 20, and the first positioning member 22 and the second positioning member 15 are detachably connected.

[0114] The first positioning element 22 and the second positioning element 15 are arranged opposite to each other. The first positioning element 22 and the second positioning element 15 are used to position the cover plate 20 and the base 10 relative to each other, so that the relative position of the cover plate 20 and the base 10 is more accurate and stable. When the first positioning element 22 and the second positioning element 15 are connected, the cover plate 20 and the base 10 are in the correct relative position.

[0115] The first positioning element 22 and the second positioning element 15 are detachably connected, which also facilitates the detachable connection between the fastener 42 and the base 10, thus achieving a detachable connection between the cover plate 20 and the base 10. The first positioning element 22 and the second positioning element 15 can also jointly support the cover plate 20, allowing the cover plate 20 to move parallel to the base 10, preventing the cover plate 20 from tilting during movement, which helps improve the stability of the cover plate 20 during the fastening process towards the base 10, thereby improving the sealing performance of the container sealing device 100 on the container 50.

[0116] When the container sealing device 100 seals the container 50, the cover plate 20 moves toward the base 10, the distance between the cover plate 20 and the base 10 decreases, and the connection between the first positioning member 22 and the second positioning member 15 becomes tighter.

[0117] The number of first positioning elements 22 can be multiple, and the multiple first positioning elements 22 are evenly spaced on the surface of the cover plate 20 facing the base 10. The first positioning elements 22 are spaced apart from the first mounting holes 21 and the second mounting holes 31 to avoid interference between the first positioning elements 22 and the fasteners 42. Optionally, the sealing element 30 is located in the central area of ​​the cover plate 20, and the first positioning elements 22 are located around the periphery of the cover plate 20. The first positioning elements 22 are spaced apart from the sealing element 30, and the multiple first positioning elements 22 are evenly spaced around the sealing element 30 around the periphery of the cover plate 20.

[0118] There can be multiple second positioning elements 15, which are evenly spaced on the surface of the base 10 facing the cover plate 20. The second positioning elements 15 are spaced apart from the limiting part 13 and the fastening part 14 to avoid interference between the second positioning elements 15 and the fastener 42. It is understood that the number of second positioning elements 15 is the same as the number of first positioning elements 22, and the second positioning elements 15 and the first positioning elements 22 are arranged in a one-to-one correspondence.

[0119] The first positioning element 22 can be a pin, and the second positioning element 15 can be a socket; or, the first positioning element 22 can be a socket, and the second positioning element 15 can be a pin.

[0120] Optionally, at least one of the first positioning member 22 and the second positioning member 15 is provided with a positioning part. The positioning part is used to limit the degree of cooperation between the first positioning member 22 and the second positioning member 15 so that there is always a gap between the cover plate 20 and the base 10, and to regulate the squeezing force of the cover plate 20 on the container 50, so as to avoid the gap between the cover plate 20 and the base 10 being too small, the squeezing force of the cover plate 20 on the container 50 being too large, which would cause the container 50 to break.

[0121] Optionally, the positioning part can be located between the first positioning member 22 and the second positioning member 15. The positioning part is used to increase the friction at the contact position of the first positioning member 22 and the second positioning member 15, thereby limiting the degree of fit between the first positioning member 22 and the second positioning member 15.

[0122] In one implementation, please refer to Figure 1 , Figure 5 and Figure 7 The base 10 also includes a support member 16, one end of which is connected to one of the cover plate 20 and the base 10. When the cover plate 20 and the base 10 are connected, the other end of the support member 16 abuts against the other of the cover plate 20 and the base 10, so that the support member 16 is located between the cover plate 20 and the base 10.

[0123] Optionally, one end of the support member 16 is detachably connected to the surface of the base 10 facing the cover plate 20, and the other end abuts against the surface of the cover plate 20 facing the base 10.

[0124] During the sealing process of container 50 by container sealing device 100, cover plate 20 moves towards base 10. During this movement, cover plate 20 may tilt, causing excessive friction at the contact points of the first positioning member 22 and the second positioning member 15. This can lead to jamming of cover plate 20 as it moves towards base 10, affecting the sealing efficiency and performance of container sealing device 100. By providing a support member 16 between base 10 and cover plate 20, the support member 16 assists in supporting cover plate 20 as it moves towards base 10, helping to prevent excessive tilting angle of cover plate 20 during movement. Simultaneously, the support member 16 has specific dimensions, ensuring a consistent distance between cover plate 20 and base 10, preventing excessive pressure from cover plate 20 on container 50 and potential damage to container 50 due to insufficient distance.

[0125] Optionally, the support member 16 includes a rigid portion 161 and an elastic portion 162 connected together. One of the base 10 and the cover plate 20 is connected to the rigid portion 161, and the other abuts against the elastic portion 162. For example, the rigid portion 161 is connected to the base 10, and the end of the elastic portion 162 away from the rigid portion 161 abuts against the cover plate 20. The elastic portion 162 can deform under pressure. During the movement of the cover plate 20 toward the base 10, the elastic portion 162 is compressed, thereby ensuring that the cover plate 20 moves smoothly toward the base 10. At the same time, the elastic portion 162 can also convert part of the compressive force of the support member 16 on the cover plate 20 into elastic force, avoiding excessive compressive force of the support member 16 on the cover plate 20, which could damage the cover plate 20.

[0126] Optionally, the elastic part 162 is frustum-shaped, and the area of ​​the surface of the elastic part 162 away from the rigid part 161 is smaller than the area of ​​the surface where the elastic part 162 is connected to the rigid part 161. For example, when the elastic part 162 abuts against the cover plate 20, the projected area of ​​the surface of the elastic part 162 in contact with the cover plate 20 on the base 10 is smaller than the projected area of ​​the surface where the elastic part 162 is connected to the rigid part 161 on the base 10.

[0127] The smaller surface area of ​​the elastic portion 162 in contact with the cover plate 20 prevents the surface from becoming too large, which could lead to irregular deformation and improve the stability of the support member 16 against the cover plate 20. Simultaneously, the beveled outer surface of the elastic portion 162 reduces its volume, preventing it from becoming too rigid and more prone to deformation. The elastic portion 162 can be made of silicone.

[0128] The number of support members 16 can be multiple. Multiple support members 16 are evenly spaced on the surface of the base 10 facing the cover plate 20 so that multiple support members 16 can evenly assist in supporting the cover plate 20 and improve the stability of the cover plate 20 during the fastening process towards the base 10.

[0129] The support member 16, the limiting part 13, the fastening part 14, and the second positioning member 15 are all spaced apart to avoid interference between the support member 16 and the fastener 42 and the second positioning member 15. Optionally, multiple support members 16 are evenly spaced around the perimeter of the base 10, and multiple support members 16 and multiple second positioning members 15 are alternately spaced to achieve uniform support of the cover plate 20 by the support members 16 and the second positioning members 15, thereby improving the stability of the cover plate 20.

[0130] In one implementation, please refer to Figure 8 The cover plate 20 has a first pressure relief hole 23, which penetrates the cover plate 20. Optionally, the first pressure relief hole 23 penetrates the cover plate 20 from the cover plate 20 toward the base 10.

[0131] The first pressure relief hole 23 is opposite to the seal 30, and the distribution area of ​​the first pressure relief hole 23 at least partially overlaps with the orthographic projection area of ​​the seal 30 on the cover plate 20. That is, the orthographic projection of the first pressure relief hole 23 on the base 10 is at least partially within the range of the orthographic projection of the seal 30 on the base 10, and the seal 30 at least partially closes the first pressure relief hole 23 on the side of the cover plate 20 near the base 10.

[0132] When the container 50 of the container sealing device 100 is sealed, one end of the opening of the container 50 abuts against the sealing element 30. The container 50 presses the sealing element 30 from the base 10 toward the cover plate 20. The sealing element 30 deforms after being pressed. The first pressure relief hole 23 connects the gap space between the sealing element 30 and the cover plate 20 and the external space. It is used to discharge the air in the gap space between the sealing element 30 and the cover plate 20 when the sealing element 30 deforms. This helps to ensure the overall flatness of the sealing element 30 after being pressed and avoids some areas of the sealing element 30 from warping up, which would affect the sealing performance of the sealing element 30 to the opening of the container 50.

[0133] The first pressure relief hole 23 and the sleeve assembly 40 are spaced apart to prevent the sleeve assembly 40 from blocking the first pressure relief hole 23 and affecting the pressure relief performance of the first pressure relief hole 23.

[0134] There can be multiple first pressure relief holes 23, which are arranged in an array on the cover plate 20. The shape and size of the multiple first pressure relief holes 23 can be exactly the same.

[0135] Optionally, the seal 30 can be directly connected to the cover plate 20 by adhesive bonding, or the seal 30 can be detachably connected to the cover plate 20; this is not limited here.

[0136] In one implementation, please refer to Figure 9 and Figure 10 The container sealing device 100 also includes a first mating component and a second mating component. The first mating component is disposed on the side of the cover plate 20 facing the seal 30, and the second mating component is connected to the side of the seal 30 facing the cover plate 20. The first mating component and the second mating component are detachably connected so that the seal 30 and the cover plate 20 are detachably connected, which facilitates the replacement of the seal 30.

[0137] Optionally, when the cover plate 20 is placed on the base 10, the orthographic projection of the second mating component on the cover plate 20 coincides with the orthographic projection of the first mating component on the cover plate 20. At this time, the sealing component 30 is in the correct set position relative to the cover plate 20, which helps to improve the accuracy of the position of the sealing component 30 during installation and avoids the sealing component 30 from being misaligned after installation, thus reducing the sealing performance of the sealing component 30 on the container 50.

[0138] Optionally, the first mating component is a magnet, and the second mating component is a magnetic attractor. A magnetic force is generated between the magnet and the magnetic attractor to connect the sealing element 30 and the cover plate 20. Preferably, the second mating component can be an iron sheet, such as a stainless steel sheet. Alternatively, the first mating component can be a hook-and-loop adhesive component, and the second mating component can be a ring-and-loop adhesive component. A large frictional force is generated between the hook-and-loop adhesive component and the ring-and-loop adhesive component to connect the sealing element 30 and the cover plate 20, and to facilitate the removal of the sealing element 30 from the cover plate 20.

[0139] In one implementation, please refer to Figure 9 and Figure 10 The sealing element 30 includes a connected high-viscosity part and a low-viscosity part, which are stacked together. The high-viscosity part is connected to the cover plate 20, and the low-viscosity part is used to seal the opening of the container 50 when the cover plate 20 is placed on the base 10. The viscosity of the low-viscosity part is lower than that of the high-viscosity part, so that the part of the sealing element 30 that contacts the container 50 has a lower viscosity, so as to avoid the large adhesive force between the sealing element 30 and the container 50 when the container 50 is unsealed, which would affect the normal unsealing of the container 50 or lift the container 50.

[0140] Optionally, both the high-viscosity and low-viscosity portions are layered structures, with the high-viscosity portion being thicker than the low-viscosity portion in the direction from the cover plate 20 to the seal 30. The thickness of the low-viscosity portion can be 0.05mm-0.2mm, for example, 0.05mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, 0.18mm, 0.2mm, or other values, to ensure that the low-viscosity portion has a certain degree of flexibility and will not deform severely due to being too thin or deteriorate in sealing effect due to being too thick. The thickness of the high-viscosity portion can be 3-8mm, for example, 3mm, 4mm, 4.5mm, 5mm, 6mm, 7mm, 8mm, or other values. The high-viscosity portion has better elasticity, allowing the seal 30 to deform when the cover plate 20 covers the base 10, thereby improving the sealing performance of the seal 30 on the container 50.

[0141] Optionally, the high-tack portion can be made of silicone, while the low-tack portion can be made of polyfluoroalkoxy (PFA). PFA has a low coefficient of friction and non-stick properties, and is resistant to high temperatures. It is understood that the low-tack portion can also be a film such as PTFE, FEP, or PE.

[0142] In one implementation, please refer to Figure 11 The surface of the cover plate 20 facing away from the seal 30 is provided with ribs 24. The sleeve assembly 40 is connected to the area of ​​the cover plate 20 where the ribs 24 are provided. The orthogonal projection area of ​​the ribs 24 on the cover plate 20 is greater than or equal to the orthogonal projection area of ​​the sleeve body 411 on the cover plate 20, so as to increase the structural strength at the connection between the cover plate 20 and the sleeve assembly 40.

[0143] The number of ribs 24 can be multiple, and the multiple ribs 24 are spaced apart on the surface of the cover plate 20 and are evenly distributed on the surface of the cover plate 20 to uniformly improve the structural strength of the cover plate 20. Optionally, the cover plate 20 is rectangular in shape, and the multiple ribs 24 extend in a straight line along the length direction of the cover plate 20. The container sealing device 100 has multiple sleeve assemblies 40, which are arrayed on the cover plate 20. Multiple sleeve assemblies 40 are present at a single rib 24, and the multiple sleeve assemblies 40 are spaced apart along the length direction of the cover plate 20.

[0144] The surface of the cover plate 20 facing away from the sealing element 30 has ribs 24, which improves the overall strength of the cover plate 20. This allows for an adaptive reduction in the thickness of the cover plate 20, making it thinner and lighter while maintaining a certain structural strength, thus reducing the overall volume and weight of the container sealing device 100. When the moving plate 301 of the pressing device 300 presses the cover plate 20 and the base 10 together, the contact point between the moving plate 301 and the cover plate 20 can be located at the ribs 24 to increase the structural strength of the area where the moving plate 301 acts on the cover plate 20.

[0145] In one implementation, please refer to Figure 5 and Figure 6 The base 10 includes a housing 11 and a limiting plate 12. The limiting plate 12 is located on the side of the housing 11 near the cover plate 20. The limiting plate 12 and the housing 11 are detachably connected. The limiting plate 12 has a limiting part 13, which is a limiting hole for inserting and fixing with the container 50. The opening of the container 50 protrudes from the limiting part 13.

[0146] Optionally, the base 10 includes a buffer 17 located between the housing 11 and the limiting plate 12, which supports the container 50. The container 50 is sandwiched between the seal 30 and the buffer 17. Both the seal 30 and the buffer 17 are elastic and can deform under pressure. The hardness of the seal 30 is greater than or equal to the hardness of the buffer 17, so that during the sealing process of the container 50 at the container sealing device 100, the container 50 presses against the buffer 17 from the cover plate 20 toward the base 10. The buffer 17 deforms to different degrees at corresponding locations of different containers 50, ensuring that the height of multiple containers 50 protruding from the top surface of the base 10 is the same, thus ensuring the sealing consistency of all containers 50 and improving the sealing effect of multiple containers 50. In addition, the buffer 17 also protects the container 50, preventing it from breaking due to excessive pressure.

[0147] Optionally, the material of the buffer 17 and the material of the seal 30 can be the same or similar, and the structure of the buffer 17 and the composition of the seal 30 can be the same or similar.

[0148] Optionally, there are multiple limiting parts 13, which are arranged in an array on the limiting plate 12. Each limiting part 13 corresponds to a fixed container 50, so that the limiting part 13 and the container 50 correspond one-to-one. Each container 50 abuts against the buffer 17, so that the buffer 17 deforms to different degrees when supporting different containers 50, so that the multiple containers 50 protrude from the top surface of the base 10 at the same height, ensuring the sealing consistency of all containers 50.

[0149] Optionally, the surface of the housing 11 facing the limiting plate 12 has a groove for accommodating the buffer member 17. The bottom wall of the groove has a second pressure relief hole, and the distribution area of ​​the second pressure relief hole at least partially overlaps with the orthographic projection area of ​​the buffer member 17 on the bottom wall of the groove. When the container sealing device 100 seals the container 50, the end of the container 50 facing away from the opening abuts against the buffer member 17. The container 50 presses the buffer member 17 from the cover plate 20 toward the base 10. The buffer member 17 deforms after being pressed. The second pressure relief hole connects the groove and the external space, and is used to discharge the air in the groove when the buffer member 17 deforms and to provide deformation space for the deformation of the buffer member 17. The second pressure relief hole relieves pressure on the groove, which helps to ensure the overall flatness of the buffer member 17 after being compressed and avoids some areas of the buffer member 17 from warping up, affecting the support of the buffer member 17 for the container 50.

[0150] Optionally, the limiting plate 12 has a third mating member, and the housing 11 has a fourth mating member. The third and fourth mating members are detachably connected, allowing the limiting plate 12 and the housing 11 to be detachably connected. The fourth mating member protrudes from the surface of the housing 11 facing the limiting plate 12. The buffer member 17 has a third mounting hole, and the fourth mating member can be accommodated in the third mounting hole, allowing the fourth mating member to pass through the third mounting hole and connect with the third mating member at the limiting plate 12. To prevent the housing 11 from bending and deforming during heating, multiple screw holes are provided in the near-central area of ​​the housing 11. The fourth mating member can be a boss (communicating with the screw holes and having a certain rigidity) surrounding the screw holes on the housing 11. The buffer member 17 has a third mounting hole for the boss to pass through, and the height of the boss is less than the thickness of the buffer member 17. The limiting plate 12 and the housing 11 are fastened together by screws.

[0151] Optionally, the outer peripheral surface of the limiting plate 12 is provided with multiple through holes to reduce the weight of the base 10.

[0152] Optionally, the limiting plate 12 has a flange that protrudes from the outer peripheral surface of the limiting plate 12, and the flange is used to simplify the removal of the base 10.

[0153] This application also provides a container sealing device 1000, please refer to [link / reference]. Figure 12 and Figure 13The container sealing device 1000 includes a fastening device 200 and a container sealing device 100 as described in any of the above embodiments. The container sealing device 100 is used to carry a container 50 with an opening. When the cover plate 20 of the container sealing device 100 is placed on the base 10, the fastening device 200 extends into the sleeve 41 of the container sealing device 100 and contacts the fastener 42 of the container sealing device 100. The fastening device 200 rotates the fastener 42 to seal or unseal the container 50.

[0154] The fastening device 200 includes a rotating member 201 and a moving component. The rotating member 201 acts on the fastener 42, causing the fastener 42 to reciprocate within the sleeve 41. The moving component is connected to the rotating member 201 and is used to drive the rotating member 201 to move, so that the rotating member 201 contacts the fastener 42.

[0155] Optionally, the rotating component 201 is used to rotate the fastener 42. The rotating component 201 can rotate the fastener 42 in a clockwise or counterclockwise direction to achieve the connection and disassembly of the cover plate 20 and the base 10.

[0156] When the rotating component 201 acts on the fastener 42, the rotating component 201 enters the channel enclosed by the sleeve 41 and contacts the fastener 42. The rotating component 201 tightens the fastener 42, increasing the fit between the fastener 42 and the base 10. The cover plate 20 moves toward the base 10 and seals the opening of the container 50. When the rotating component 201 loosens the fastener 42, the fit between the fastener 42 and the base 10 decreases, the cover plate 20 is disconnected from the base 10, and the cover plate 20 can be removed from the base 10 to unseal the container 50.

[0157] The rotating component 201 includes, but is not limited to, an electric screwdriver (also known as an electric screwdriver), and correspondingly, the fastener 42 is a screw, which is used to tighten and loosen.

[0158] The moving components include, but are not limited to, multi-axis robotic arms (such as three-axis, four-axis, six-axis, and seven-axis robotic arms) and single-axis or multi-axis translation mechanisms (such as XYZ-axis translation mechanisms). When the moving component is a robotic arm, a quick-change male connector can be provided on the robotic arm, and a quick-change female connector 2011 can be provided on the rotating component 201 to realize quick-change connection between the moving component and the rotating component 201.

[0159] The fastening device 200 also includes a support frame 202, on which the rotating component 201 can be placed when it is not needed. When the rotating component 201 is needed, the robotic arm connects to the rotating component 201 on the support frame 202 and drives the rotating component 201 to move.

[0160] The container sealing device 1000 also includes a pressing device 300, which includes a movable plate 301, a driving assembly 302, and a fixed plate 303. The fixed plate 303 is used to place and support the container sealing device 100. The movable plate 301 and the fixed plate 303 are arranged opposite to each other. The movable plate 301 is used to cooperate with the fixed plate 303 to press the cover plate 20 and the base 10 of the container sealing device 100. The driving assembly 302 is connected to the movable plate 301 and is used to drive the movable plate 301 to move and adjust the pressure of the movable plate 301 on the container sealing device 100. Specifically, the driving assembly 302 can be fixedly mounted on the fixed plate 303. The output end of the driving assembly 302 is connected to the movable plate 301. When the driving assembly 302 is working, it drives the movable plate 301 to move, so that the movable plate 301 moves closer to or further away from the fixed plate 303.

[0161] The number of movable plates 301 can be multiple, and multiple movable plates 301 are arranged at intervals, and multiple movable plates 301 together fix the container sealing device 100.

[0162] Optionally, the drive assembly 302 is driven by a cylinder, and the pressing device 300 further includes a switching valve 305 and a pressure proportional valve 304. The pressure proportional valve 304 is connected to an air source, and the switching valve 305 is connected to both the pressure proportional valve 305 and the drive assembly 302. The switching valve 305 is used to control the opening and closing of the air path input to the drive assembly 302, that is, to control the opening and closing of the drive assembly 302's drive on the moving plate 301; the pressure proportional valve 304 is used to adjust the air pressure input to the drive assembly 302, that is, to control the pressure exerted by the drive assembly 302 on the moving plate 301 to compress the container sealing device 100.

[0163] When sealing the container sealing device 100, the container sealing device 100 is first placed on the fixed plate 303. The driving component 302 controls the moving plate 301 to press the container sealing device 100 towards the fixed plate 303. By adjusting the driving component 302, the pressure applied by the moving plate 301 to the container sealing device 100 is adjusted to achieve the fixation of the container sealing device 100. Then, the rotating component 201 is connected to the moving component. The moving component drives the rotating component 201 to move so that the rotating component 201 is opposite to the fastener 42. The rotating component 201 acts on the fastener 42, causing the fastener 42 to rotate, thereby achieving the sealing of the container sealing device 100.

[0164] It is understood that the container sealing device 1000 in this embodiment has the container sealing device 100 in the above embodiments. Therefore, the container sealing device 1000 in this embodiment has all the technical effects of the container sealing device 100 in the above embodiments. Since the technical effects of the container sealing device 100 have been fully explained in the above embodiments, they will not be repeated here.

[0165] In one implementation, please refer to Figure 14 The movable plate 301 includes a first connecting plate 3011 and a plurality of first pressure plates 3012 connected to the first connecting plate 3011. The first connecting plate 3011 is connected to a drive assembly 302, which drives the first connecting plate 3011 to move so that the first connecting plate 3011 drives the plurality of first pressure plates 3012 to contact the cover plate 20.

[0166] Multiple first pressure plates 3012 are evenly distributed on the first connecting plate 3011, and the distance between two adjacent first pressure plates 3012 is greater than the radial dimension of the sleeve 41, so that the sleeve 41 is accommodated in the space between two adjacent first pressure plates 3012, avoiding interference between the multiple first pressure plates 3012 and the sleeve 41 when they contact the cover plate 20.

[0167] When the movable plate 301 presses the cover plate 20 and the base 10, multiple first pressure plates 3012 are evenly distributed on the cover plate 20 to improve the uniformity of the pressure applied by the movable plate 301 to the cover plate 20, ensure the levelness of the cover plate 20, and thus improve the sealing performance of the container sealing device 100.

[0168] In one implementation, please refer to Figure 15 The movable plate 301 includes a second connecting plate 3013 and a second pressure plate 3014 connected to the second connecting plate 3013. The second connecting plate 3013 is connected to a drive assembly 302, which drives the second connecting plate 3013 to move, causing the second connecting plate 3013 to drive the second pressure plate 3014 to contact the cover plate 20. The second connecting plate 3013 and the fixed plate 303 form an accommodating space, within which the drive assembly 302, the switching valve 305, and the pneumatic proportional valve 304 can be disposed, i.e., below the fixed plate 303. This arrangement allows for a compact overall structure and saves space.

[0169] The second pressure plate 3014 has a clearance portion 3015, which passes through the second pressure plate 3014 along the direction from the second pressure plate 3014 to the fixed plate 303. The clearance portion 3015 is used to avoid the sleeve 41. The orthogonal projection area of ​​the clearance portion 3015 on the fixed plate 303 is greater than or equal to the orthogonal projection area of ​​the sleeve 41 on the fixed plate 303, so that the sleeve 41 can pass through the second pressure plate 3014 through the clearance portion 3015, so that the second pressure plate 3014 contacts the cover plate 20, and avoids interference between the second pressure plate 3014 and the sleeve 41 when they contact the cover plate 20.

[0170] Optionally, there may be multiple clearance portions 3015, which are spaced apart on the second pressure plate 3014. The distribution of the clearance portions 3015 corresponds to the distribution of the sleeve assemblies 40 on the cover plate 20. The clearance portions 3015 can be arranged in an array on the second pressure plate 3014. There may also be multiple sleeve assemblies 40, with each clearance portion 3015 facing at least one sleeve assembly 40, so that each clearance portion 3015 passes through at least one sleeve assembly 40. The minimum distance between two adjacent clearance portions 3015 is a first distance, and the minimum distance between two sleeve assemblies 40 facing different clearance portions 3015 is a second distance. The first distance is less than the second distance, so that the size of the clearance portion 3015 is larger than the size of the sleeve assembly 40, facilitating the sleeve assembly 40 to pass through the clearance portion 3015 and preventing interference between the second pressure plate 3014 and the sleeve 41 when in contact with the cover plate 20.

[0171] This application also provides a method for testing sealing performance; please refer to [link / reference]. Figure 16 The sealing test method is applied to the container sealing device 1000 described above, in which a container 50 containing a sample solution has been placed; the method includes:

[0172] Step S10: Determine the initial pressure value;

[0173] Step S20: Control the pressing device 300 to press the cover plate 20 with an initial pressure value so that the cover plate 20 is pressed against the base 10;

[0174] Step S30: Control the fastening device 200 to drive the fastener 42 to rotate so that the cover plate 20 and the base 10 are connected and the container 50 is sealed;

[0175] Step S40: Heat the container sealing device 100, let it stand for a preset time, and then detect the change in liquid level in the container 50 or the change in weight of the container sealing device 100.

[0176] Step S50: Determine whether the change in liquid level in container 50 is less than or equal to a first set value, or whether the change in weight of container sealing device 100 is less than or equal to a second set value; if the determination result is yes, then proceed to step S60; if the determination result is no, then proceed to step S70.

[0177] Step S60: Determine whether the sealing performance of the container sealing device 100 meets the experimental requirements under the initial pressure value.

[0178] Step S70: Adjust the pressure value to obtain the adjusted pressure value. Repeat steps S20 to S50 until the adjusted current pressure value makes the sealing performance of the container sealing device 100 meet the experimental requirements.

[0179] Specifically, in step S50, if the change in liquid level is less than or equal to the first set value, or the change in weight is less than or equal to the second set value, it is determined that the sealing performance of the container sealing device 100 meets the experimental requirements under the initial pressure value. Otherwise, the pressure value in step S10 is adjusted, and steps S20 to S50 are repeated. In step S20, the pressing device 300 is controlled to press against the cover plate 20 with the adjusted current pressure value. The adjusted pressure value is greater than the initial pressure value until the sealing performance of the container sealing device 100 meets the experimental requirements.
