Description

Technical Field

[0002] In the field of sample storage, accessing samples often requires opening an entire access channel, leaving other biological samples that do not need to be accessed exposed to room temperature, which can easily damage the biological samples and cause the loss of the cold source inside the storage chamber, thereby increasing the cost of the cold source. Moreover, during use, due to poor sealing, the access channel often experiences internal and external convection, leading to frost formation. At the same time, the robotic arm and the storage rack shelves often interfere with each other, thus affecting the efficiency of access.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0038] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a sealing mechanism for a sample storage device, which includes a storage compartment 1. The storage compartment 1 is provided with an operation area and a storage access channel 2 in the operation area. Multiple sets of sealing components 7 are provided on the storage access channel 2. The multiple sets of sealing components 7 can seal the storage access channel 2. A gripper mechanism 3 is provided on one side of the storage access channel 2. The gripper mechanism 3 can drive the sealing components 7 to move and expose a portion of the storage access channel 2. The gripper mechanism 3 can access the plate rack in the storage compartment 1 through the portion of the storage access channel 2.

[0039] Preferably, by setting up an access channel 2 in the operating area, multiple sets of sealing components 7 can be used to seal the access channel 2. During access, only one set of sealing components 7 needs to be opened to expose a portion of the access channel 2, i.e., the access port 4, thus ensuring that there is no large-scale internal and external temperature exchange during the access process.

[0040] It should be noted that the gripper mechanism 3 can perform horizontal telescopic movement and vertical movement; the gripper mechanism 3 can move the sealing component 7 and expose the access port 4, and then the access port can be used to scoop up the plate rack of the storage rack or transport the plate rack to the storage rack.

[0041] It should be noted that the gripper mechanism 3 shown in the figure does not have an external drive three-axis mechanism. The external drive three-axis mechanism can be used to drive the gripper mechanism 3 to move up and down, and can also drive the gripper mechanism 3 away from the operating area. Furthermore, the access channel 2 is configured to correspond with the storage rack in the storage compartment 1, and the access channel 2 and the storage slot on the storage rack correspond one-to-one to form multiple access ports 4, and a sealing component 7 is provided in the access port 4.

[0042] Preferably, the access channel 2 is vertically arranged and corresponds to the vertical storage rack of the storage rack. The access channel 2 is sealed by multiple sets of sealing components 7. When accessing, only one set of sealing components 7 needs to be opened to expose a set of access ports 4. The access ports 4 are corresponding to the storage slots of the storage rack. The gripper mechanism 3 can grip the sample plate rack in the storage slot of the storage rack through the access ports 4.

[0043] Furthermore, the gripper mechanism 3 includes a storage component 31 and a moving component 32; the storage component 31 is provided with the moving component 32, the storage component 31 can drive the moving component 32 to move, the moving component 32 can drive the sealing component 7 to move and expose the storage port 4, and the storage component 31 can access the inner plate frame of the storage compartment 1 through the storage port 4.

[0044] Furthermore, the moving component 32 includes a hook part 321, which is disposed at the front end of the access component 31. The hook part 321 can hook the sealing component 7 away from the access port 4, and the access component 31 can drive the hook part 321 and the sealing component 7 to rise and fall.

[0045] Preferably, a moving component 32 is provided on the access component 31. The moving component 32 can move the sealing component 7 to expose the access port 4, and the access port 4 can be used to access the internal plate rack sample.

[0046] Furthermore, the access component 31 includes a support, a slider, and an access member; the slider is disposed on the support, and the access member is disposed on the slider; the slider and the access member can slide on the support, the access member can slide on the slider, and the access member can access the sample tray.

[0047] Preferably, the support member can support the sliding member and the access member. The sliding member and the access member can perform telescopic movements on the support member, and the access member can telescopically move on the sliding member, realizing two-stage telescopic movements and increasing the movement stroke.

[0048] Preferably, the access device is provided with a plate rack slot, which can move at least two sets of plate racks. The storage slot on the storage rack is provided with support steps on both sides, which can support the biological plate rack. The access device extends into the storage slot and can store or grab the biological plate rack by a small range of lifting and lowering.

[0049] Furthermore, it also includes a middle frame assembly 6, which is located on one side of the access channel 2, and has multiple sets of sealing assemblies 7 inside the middle frame assembly 6. The middle frame assembly 6 can drive the multiple sets of sealing assemblies 7 to move up and down.

[0050] Preferably, the middle frame assembly 6 is provided with multiple sets of sealing assemblies 7, which can ensure that the access channel 2 is not exposed during the lifting and lowering process.

[0051] Preferably, the middle frame assembly 6 is equipped with multiple sets of sealing assemblies 7. The middle frame assembly 6 can drive multiple sets of sealing assemblies 7 to move up and down within a small range simultaneously. This is to solve the problem of interference between the access port 4 and the storage slot on the storage rack when they are not aligned, which would prevent the gripper mechanism 3 from entering the storage slot on the storage rack inside the storage compartment 1 through the access port 4 and thus prevent access operations. This short-distance movement method can effectively solve the micro-interference problem between the gripper mechanism 3 and the storage slot and shelf, thereby achieving single-layer alignment between the access port 4 and the storage slot on the internal storage rack.

[0052] Furthermore, the middle frame assembly 6 includes a drive member 61 and a middle frame support member 62. The drive member 61 is disposed on the upper end of the middle frame support member 62. The drive member 61 can drive the middle frame support member 62 to move up and down. The middle frame support member 62 can support multiple sets of sealing assemblies 7.

[0053] Preferably, the interior of the middle frame support 62 is hollow, and multiple sets of sealing components 7 are disposed inside the middle frame support 62. The sealing components 7 can be used to seal the access channel 2, and the middle frame support 62 also has a certain sealing effect on the access channel 2.

[0054] Preferably, the upper drive component 61 can drive the middle frame support component 62 to move up and down a short distance, so as to achieve single-layer alignment between the access port 4 and the storage slot on the internal storage rack, thus avoiding interference problems.

[0055] Furthermore, the sealing assembly 7 includes a square hole plug 71 with a gripping hole 72. The square hole plug 71 is magnetically connected to the middle frame support 62. The hooking part 321 can hook the square hole plug 71 through the gripping hole 72, and the hooking part 321 can magnetically connect the hooked square hole plug 71 to the outer surface of any other set of square hole plugs 71.

[0056] Furthermore, the moving component 32 includes a hook part 321, which is disposed at the front end of the access component 31. The hook part 321 can hook the sealing component 7 away from the access port 4, and the access component 31 can drive the hook part 321 and the sealing component 7 to rise and fall.

[0057] Preferably, multiple sets of square hole plugs 71 are disposed inside the middle frame support member 62. The middle frame support member 62 can support the multiple sets of square hole plugs 71. The square hole plugs 71 are magnetically connected to the middle frame support member 62. The outer side of the square hole plug 71 is provided with a gripping hole 72. The hook part 321 can be inserted into the gripping hole 72 and pulled. The square hole plug 71 is easily released from the magnetic connection of the middle frame support member 62. The hook part 321 pulls the square hole plug 71 out horizontally, and then drives the square hole plug 71 to rise and fall. The square hole plug 71 is placed on the outer side of an adjacent or any set of square hole plugs 71 and magnetically connected together. At this time, the access port is exposed, and the storage rack board can be accessed through the access component 31. After the access is completed, it is moved to the side of the square hole plug 71 by lifting and lowering, and the square hole plug 71 is placed back in its original position.

[0058] Furthermore, it also includes a sealing door mechanism 5, which can seal the operating area.

[0059] Preferably, by setting the sealing door mechanism 5, the sealing door mechanism 5 can be opened before the storage and retrieval operation to expose the operation area for operation. After the storage and retrieval is completed, the sealing door mechanism 5 is used to seal the operation area, thereby achieving the first layer of sealing by the sealing component 7 and the second layer of sealing by the sealing door mechanism 5. Through the double sealing method, energy leakage and consumption are avoided.

[0060] In summary, this invention, by setting multiple sets of sealing components 7 within the access channel 2, effectively seals and insulates the storage chamber 1, improving sealing performance, preventing frost formation due to internal and external convection during operation, and reducing energy consumption and costs. During access, only one set of sealing components 7 needs to be opened to expose one access port 4, allowing the gripper mechanism 3 to access samples within the storage chamber 1. This effectively reduces the area for heat exchange and air convection, resulting in better insulation. The gripper mechanism 3 can open any set of sealing components 7, enabling flexible access to samples at different positions on the storage rack within the storage chamber 1, meeting diverse sample access needs. The middle frame component 6 can drive multiple sets of sealing components 7 for micro-adjustment, resolving the micro-interference problem between the gripper mechanism 3 and the internal storage rack shelves. Example 2

[0061] Reference Figures 5-12This is the second embodiment of the present invention. In the previous embodiment, the sample storage device sealing mechanism includes a storage compartment 1, an operation area on the storage compartment 1, a storage access channel 2 in the operation area, and multiple sets of sealing components 7 on the storage access channel 2. The multiple sets of sealing components 7 can seal the storage access channel 2. A gripper mechanism 3 is provided on one side of the storage access channel 2. The gripper mechanism 3 can drive the sealing components 7 to move and expose a portion of the storage access channel 2. The gripper mechanism 3 can access the plate rack in the storage compartment 1 through the portion of the storage access channel 2.

[0062] Preferably, by setting up an access channel 2 in the operating area, multiple sets of sealing components 7 can be used to seal the access channel 2. During access, only one set of sealing components 7 needs to be opened to expose a portion of the access channel 2, i.e., the access port 4, thus ensuring that there is no large-scale internal and external temperature exchange during the access process.

[0063] It should be noted that the gripper mechanism 3 can perform horizontal telescopic movement and vertical movement; the gripper mechanism 3 can move the sealing component 7 and expose the access port 4, and then the access port can be used to scoop up the plate rack of the storage rack or transport the plate rack to the storage rack.

[0064] It should be noted that the gripper mechanism 3 shown in the figure does not have an external drive three-axis mechanism. The external drive three-axis mechanism can be used to drive the gripper mechanism 3 to move up and down, and can also drive the gripper mechanism 3 away from the operating area. Furthermore, the access channel 2 is configured to correspond with the storage rack in the storage compartment 1, and the access channel 2 and the storage slot on the storage rack correspond one-to-one to form multiple access ports 4, and a sealing component 7 is provided in the access port 4.

[0065] Preferably, the access channel 2 is vertically arranged and corresponds to the vertical storage rack of the storage rack. The access channel 2 is sealed by multiple sets of sealing components 7. When accessing, only one set of sealing components 7 needs to be opened to expose a set of access ports 4. The access ports 4 are corresponding to the storage slots of the storage rack. The gripper mechanism 3 can grip the sample plate rack in the storage slot of the storage rack through the access ports 4.

[0066] Furthermore, the gripper mechanism 3 includes a storage component 31 and a moving component 32; the storage component 31 is provided with the moving component 32, the storage component 31 can drive the moving component 32 to move, the moving component 32 can drive the sealing component 7 to move and expose the storage port 4, and the storage component 31 can access the inner plate frame of the storage compartment 1 through the storage port 4.

[0067] Furthermore, the moving component 32 includes a supporting part 322; the supporting part 322 is disposed on the upper front end of the moving component 32, and the access component 31 can drive the supporting part 322 to move horizontally and vertically, and the supporting part 322 can drive at least one set of sealing components 7 to rise, and expose a set of access ports 4, through which the access component 31 can access the inner plate frame of the storage compartment 1.

[0068] Preferably, the end of the abutment 322 near the sealing assembly 7 is shaped like a sickle and faces upwards.

[0069] Furthermore, the access component 31 includes a support member and a sliding extraction member 314; the sliding extraction member 314 is disposed on the support member, and the sliding extraction member 314 can slide on the support member, and the movement of the sliding extraction member 314 causes the supporting part 322 to rise.

[0070] Preferably, while the sliding extraction member 314 is moving telescopically, it can drive the supporting part 322 to rise. The supporting part 322 can be used to lift multiple sets of sealing sliders 74 along the guide rail groove 73, thereby exposing a set of access ports 4. The sliding extraction member 314 can access the internal plate frame through the access ports 4.

[0071] Preferably, the sliding extraction member 314 is provided with a plate holder groove, which can drive at least two sets of plate holders to move. The storage slot on the storage rack is provided with support steps on both sides, which can support the biological plate holder. The sliding extraction member 314 extends into the storage slot, and the biological plate holder can be stored or grabbed by a small range of lifting and lowering.

[0072] It should be noted that the supporting part 322 includes a drive plate 3221, a drive limiting plate 3222, and a supporting plate 3223. The supporting plate 3223 is provided on the upper end of the drive plate 3221 and on the side near the sealing slider 74. The supporting plate 3223 is provided with a supporting guide slope 3224. The drive plate 3221 is provided with a drive plate supporting slope 3225 on the side near the driver 3141. The drive limiting plate 3222 can limit the lifting and lowering of the drive plate 3221.

[0073] Preferably, the sliding extraction member 314 can be composed of a driver 3141, a drive shaft 3142, an extractor 3143, and a sliding roller 3144. The sliding roller is mounted on the drive shaft via a connector. The driver drives the drive shaft to rotate, and the extractor and the sliding roller located on the drive shaft can move horizontally. During the horizontal movement, the sliding roller gradually lifts one end of the supporting part 322. The sliding roller can also move at the lower end of the supporting part 322, ensuring that the supporting part 322 will not descend when the extractor is storing or retrieving samples. This avoids the phenomenon of multiple sets of sealing sliders 74 sliding downwards, which would affect the storage and retrieval operation.

[0074] Preferably, during the storage and retrieval operation, the gripper mechanism 3 first moves horizontally, and through the abutment guide slope 3224 on the abutment plate 3223, the slide rod 75 is brought into contact with the upper end of the abutment plate 3223. Driven by the driver 3141, the drive shaft 3142 rotates. Simultaneously, the drive shaft 3142 rotates, causing the extractor 3143 and the sliding roller 3144 to move horizontally. The sliding roller 3144 then drives the drive plate abutment slope 3225 at the front end of the drive plate 3221, causing the sliding roller 3144 to engage with the drive plate abutment slope 3225. When they cooperate, the sliding roller 3144 moves forward and supports the drive plate abutting slope 3225. At this time, the drive plate 3221 gradually rises, causing the sliding roller 3144 to roll below the drive plate 3221. Then, the abutting plate 3223 above will drive the slide bar 75 and the sealing slider 74 to rise. After reaching the position, a storage port 4 will be exposed. At this time, the extractor 3143 can perform storage and retrieval operations on the internal plate rack. The gripper mechanism 3 can be raised and lowered slightly as a whole, which makes it easy for the extractor 3143 to retrieve or store the plate rack.

[0075] Furthermore, the sealing assembly 7 includes sealing sliders 74, and multiple sets of sealing sliders 74 are disposed in the access channel 2. The abutment portion 322 can drive at least one set of sealing sliders 74 to rise and expose a set of access ports 4.

[0076] Furthermore, guide rail grooves 73 are provided on both sides of the access channel 2, and slide rods 75 are provided on both sides of the sealing slider 74. The slide rods 75 are located in the guide rail grooves 73, and the guide rail grooves 73 can guide the sealing slider 74 through the slide rods 75.

[0077] Preferably, the sliding extractor 314 can drive the supporting part 322 to rise when it moves. The supporting part 322 can be used to raise multiple sets of sealing sliders 74 and sliders 75 along the guide rail groove 73, thereby exposing a set of access ports 4. The sliding extractor 314 can access the internal plate frame through the access ports 4.

[0078] Furthermore, it also includes a sealing door mechanism 5, which can seal the operating area.

[0079] Preferably, by setting the sealing door mechanism 5, the sealing door mechanism 5 can be opened before the storage and retrieval operation to expose the operation area for operation. After the storage and retrieval is completed, the sealing door mechanism 5 is used to seal the operation area, thereby achieving the first layer of sealing by the sealing component 7 and the second layer of sealing by the sealing door mechanism 5. Through the double sealing method, energy leakage and consumption are avoided.

[0080] In summary, by setting multiple sets of sealing components 7 in the access channel 2, this utility model can effectively seal and insulate the storage compartment 1, improve sealing performance, avoid the problem of frost formation due to internal and external convection during operation, and reduce energy consumption and lower energy costs. By simply opening a set of sealing components 7 and exposing a set of access ports 4 during the storage and retrieval process, the storage chamber 1 can be accessed via the gripper mechanism 3. This effectively reduces the area of ​​heat exchange and air convection, resulting in better insulation. Any set of sealing components 7 can be opened via the gripper mechanism 3, thereby enabling flexible access to samples at different locations on the storage rack within the storage chamber 1, meeting diverse sample access needs. Furthermore, in this embodiment, there is no need to grip and pull out the sealing components 7. The sliding extraction member 314 can move and drive the supporting part 322 to rise. The supporting part 322 can then lift multiple sets of sealing sliders 74 and sliding rods 75 along the guide rail groove 73, thereby exposing a set of access ports 4. The sliding extraction member 314 can then access the internal rack through the access ports 4.
