"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0050] like Figures 1-4As shown, this utility model provides an automatic specimen storage and retrieval cabinet for storing specimens. The automatic specimen storage and retrieval cabinet includes a cabinet body 1, a storage and retrieval device 2, a transfer device 3, a support device 4, and a tray transfer device 5. The cabinet body 1 has a storage and retrieval opening on its side wall; the storage and retrieval device 2 includes a storage and retrieval plate 21, a storage and retrieval rail 22, and a storage and retrieval trolley. The storage and retrieval plate 21 is located inside the storage and retrieval opening and has a storage position and a retrieval position. The storage and retrieval trolley is slidably connected to the storage and retrieval rail 22, with one end located at the storage and retrieval opening. The storage and retrieval plate 21 is fixedly connected to the top of the storage and retrieval trolley 23; the transfer device 3 includes transfer grippers that are movably disposed within the cabinet body 1 along a first horizontal direction and a second horizontal direction; the support device 4 includes multiple support trays 41, which are spaced vertically within the cabinet body 1 and configured to support... The specimen tray 41 has hanging ears 411 on both sides in the second horizontal direction; the tray transfer device 5 includes a movable plate 51 and two locking cylinders. In the first horizontal direction, the movable plate 51 is spaced apart from the tray 41. The position of the movable plate 51 is adjustable in the vertical direction and can be aligned with any of the storage plate 21 and multiple trays 41 in the first horizontal direction. In the second horizontal direction, the two locking cylinders are respectively located on both sides of the movable plate 51 and are adjustable in the first horizontal direction. The movable ends of the two locking cylinders can be inserted into the through holes of the two hanging ears 411 one by one. The first horizontal direction is perpendicular to the second horizontal direction.
[0051] When a specimen needs to be stored, the specimen is placed in the storage position of the storage plate 21; the transfer gripper moves above the storage position and grips the specimen; the movable plate 51 moves vertically and aligns with the support tray 41; the locking cylinder moves horizontally to the hanging ear 411, the movable end of the locking cylinder extends out and enters the through hole of the hanging ear 411; the locking cylinder retracts horizontally and moves the support tray 41 onto the movable plate 51; the movable plate 51 moves vertically and aligns with the storage plate 21; the transfer gripper places the specimen on the support tray 41; the movable plate 51 moves vertically back to the original height of the support tray 41. The locking cylinder moves along the first horizontal direction and moves the tray 41 to its original position; the movable end of the locking cylinder extends out of the through hole of the hanging ear 411; when the specimen needs to be taken out, the above steps are reversed. The difference is that the final transfer gripper places the specimen to be taken out on the retrieval position of the storage plate 21, and the technician can directly take out the specimen. The degree of automation is high, and there is no need for technicians to open and close the cabinet door. The disturbance to the temperature, humidity, pressure and specimen itself in the cabinet is small. The storage trolley 23 can move the storage plate 21 from the inside of the cabinet 1 to the storage port, which makes it easier for operators to pick up and place specimens.
[0052] It should be noted that the cabinet 1 is equipped with a temperature sensor, a temperature regulation mechanism, a humidity sensor, a humidity regulation mechanism, a pressure sensor, and a pressure regulation mechanism to ensure that the automatic specimen retrieval cabinet can adjust the temperature, humidity, and pressure values inside the cabinet 1 according to the storage environment required by the specimens inside.
[0053] It should be noted that the locking cylinder is a cylinder structure already disclosed in the art, and the material transfer gripper is a gripper structure already disclosed in the art. The working principle and specific structure of the two will not be elaborated here.
[0054] Specifically, the supporting device 4 also includes a supporting frame 42, which is fixedly installed inside the cabinet 1. Multiple trays 41 can be placed on the supporting frame 42, and a retrieval plate 21 is located at the top of the supporting frame 42. The supporting frame 42 is configured to support multiple trays 41 simultaneously. In this embodiment, the top of the supporting frame 42 is lower than the access opening, and the retrieval rail 22 is fixedly installed at the top of the supporting frame 42.
[0055] Specifically, the tray 41 is provided with multiple storage positions, each of which can hold one specimen. Depending on the shape and volume of the specimen, the specific form of the storage position includes, but is not limited to, grooves, through holes, etc., as long as the stability of the specimen when placed in the storage position can be guaranteed.
[0056] Specifically, the transfer device 5 also includes two transfer rails 53 and two transfer trolleys 54. In the second horizontal direction, the two transfer rails 53 are fixedly connected to the two sides of the movable plate 51 in a one-to-one correspondence; the transfer trolleys 54 are slidably connected to the corresponding transfer rails 53, and the fixed end of the locking cylinder is fixedly connected to the transfer trolley 54. The transfer rails 53, transfer trolleys 54, and locking cylinders correspond one-to-one. With this configuration, the transfer rails 53 and transfer trolleys 54 cooperate to achieve position adjustment of the locking cylinder in the first horizontal direction, and the connection between the structures is simple, resulting in high transmission efficiency.
[0057] In other embodiments, mechanical gripper structures commonly used in the art can also be used to achieve the position adjustment of the locking cylinder in the first horizontal direction, without specific limitations.
[0058] More specifically, the pallet transfer device 5 also includes a lifting assembly 55, which comprises a lifting drive mechanism 551, a lead screw 552, and a lifting support 553. The lead screw 552 is housed within the cabinet 1, extending vertically and passing through the movable plate 51. One end of the lead screw 552 is fixedly connected to the output end of the lifting drive mechanism 551. The lifting support 553 is screwed to the lead screw 552 and supports the bottom of the movable plate 51. When the lifting drive mechanism 551 drives the lead screw 552 to rotate around its own axis, the lifting support 553 can lift the movable plate 51. The lifting assembly 55 allows for vertical position adjustment of the pallet transfer device 5, and the structural connections are simple, resulting in high transmission efficiency.
[0059] For example, in this embodiment, the lifting support 553 is detachably connected to the bottom of the movable plate 51 by bolts to ensure the connection strength between the two.
[0060] It should be noted that the lifting drive mechanism 551 is a motor or motor commonly used in this field that can rotate in both forward and reverse directions. Its working principle and specific structure will not be described in detail here.
[0061] More specifically, the lifting assembly 55 also includes a spring 554, and the lifting support 553 is provided with a first buffer portion 5531 and a second buffer portion 5532. The first buffer portion 5531 is spaced above the second buffer portion 5532, and the two ends of the spring 554 press against the first buffer portion 5531 and the second buffer portion 5532 respectively. With this configuration, during the lifting process of the lifting support 553, when the lifting support 553 stops suddenly, the spring 554 can buffer the inertial action of the first buffer portion 5531 and the second buffer portion 5532 through its own elastic restoring force, thereby protecting the threaded structure of the lead screw 552.
[0062] For example, in this embodiment, the first buffer portion 5531 has a limiting groove, and the second buffer portion 5532 has a limiting protrusion. When the first buffer portion 5531 and the second buffer portion 5532 approach each other in the vertical direction, the limiting protrusion can engage with the limiting groove. This arrangement, with the limiting groove and the limiting protrusion cooperating, prevents relative rotation between the first buffer portion 5531 and the second buffer portion 5532 during lifting and lowering. In other embodiments, the first buffer portion 5531 may have a limiting protrusion, and the second buffer portion 5532 may have a limiting groove.
[0063] Specifically, the material transfer device 3 further includes a first guide rail 31 and a material transfer trolley 32. The first guide rail 31 extends along a first horizontal direction and its position is adjustable along a second horizontal direction. The material transfer trolley 32 is slidably connected to the first guide rail 31, and the fixed end of the material transfer gripper is fixedly mounted on the material transfer trolley 32. With this configuration, the first guide rail 31 and the material transfer trolley 32 cooperate to achieve position adjustment of the material transfer gripper in the first horizontal direction, and the connection between the structures is simple, resulting in high transmission efficiency.
[0064] More specifically, the material transfer device 3 also includes a material transfer drive mechanism 33 and two second guide rails 34. Both second guide rails 34 extend along a second horizontal direction. A sliding contact seat 311 is provided at each end of the first guide rail 31, and the two sliding contact seats 311 are slidably connected to the two second guide rails 34 in a one-to-one correspondence. The material transfer drive mechanism 33 is configured to drive the sliding contact seats 311 to move along the second guide rails 34. With this configuration, the material transfer drive mechanism 33 and the second guide rails 34 cooperate with each other, and by simultaneously driving the two sliding contact seats 311, the position of the first guide rail 31 in the second horizontal direction is adjusted.
[0065] Specifically, the material transfer device 3 also includes a transmission assembly 35, which comprises two transmission shafts 351 and two transmission belts 352. The two transmission shafts 351 are spaced apart in the second horizontal direction and both extend along the first horizontal direction. Both ends of the transmission shafts 351 are rotatably mounted on the inner wall of the cabinet 1. The two transmission belts 352 are both annular, with one end pressing against one of the transmission shafts 351 and the other end pressing against the other. Two sliding seats 311 are fixedly connected to the two transmission belts 352 in a one-to-one correspondence. When the material transfer drive mechanism 33 drives either transmission shaft 351 to rotate around its own axial direction, the transmission belt 352 can drive the sliding seat 311 to move along the second guide rail 34. With this configuration, the two transmission shafts 351 and the two transmission belts 352 work together, and the same material transfer drive mechanism 33 can simultaneously drive both sliding seats 311 to move along the second guide rail 34, resulting in high transmission efficiency and synchronized movement of the two sliding seats 311, preventing misalignment.
[0066] In this embodiment, for example, the transmission belt 352 has a first segment 3521 and a second segment 3522 connected end-to-end. The first segment 3521 is located above the second segment 3522. When the material transfer drive mechanism 33 is activated, the first segment 3521 and the second segment 3522 move towards each other. The sliding seat 311 has a limiting hole 3110 extending in the second horizontal direction. The second segment 3522 passes through the limiting hole 3110, and the top end of the sliding seat 311 is fixedly connected to the first segment 3521. With the above arrangement, the first segment 3521 can drive the sliding seat 311 to move along the second guide rail 34. At the same time, the limiting hole 3110 and the second segment 3522 cooperate with each other to prevent the sliding seat 311 from tipping over and improve stability.
[0067] For example, in this embodiment, the material transfer drive mechanism 33 is a motor or motor commonly used in the art that can rotate in both forward and reverse directions. Its working principle and specific structure will not be described in detail here.
[0068] Alternatively, in other embodiments, the transmission component 35 may not be provided. Instead, a linear motor or cylinder structure commonly used in the art can be used as the material transfer drive mechanism 33, and two material transfer drive mechanisms 33 may be provided. Each material transfer drive mechanism 33 independently drives a sliding seat 311, thereby achieving the technical effect of moving the first guide rail 31 in the second horizontal direction by simultaneously driving the sliding seat 311.
[0069] Specifically, the automated specimen storage and retrieval cabinet also includes a processor 6, which is fixedly installed inside the cabinet body 1. The processor 6 is communicatively connected to the transfer gripper, locking cylinder, storage and retrieval trolley, transfer trolley 54, lifting drive mechanism 551, transfer trolley 32, transfer drive mechanism 33, temperature sensor, temperature regulation mechanism, humidity sensor, humidity regulation mechanism, pressure sensor, and pressure regulation mechanism. The processor 6 enables automatic control of the automated specimen storage and retrieval cabinet (such as the automatic specimen storage and retrieval process and the automatic adjustment of temperature, humidity, and pressure values).
[0070] It should be noted that the storage trolley, the material transfer trolley 32, and the tray transfer trolley 54 are all commonly used trolley structures in this field, and their working principles and specific structures will not be elaborated here.
[0071] For example, in this embodiment, the access trolley, the transfer trolley 32, and the transfer trolley 54 are all... RULMAN SHN15B. In other embodiments, the access trolley, transfer trolley 32, and transfer trolley 54 may also use other trolley structures commonly used in the art, and no specific limitation is made here.
[0072] More specifically, the automated specimen storage cabinet also includes a touch screen, which is fixedly connected to the outer wall of the cabinet 1 and is communicatively connected to the processor 6. Operators can retrieve and store specimens through the touch screen, and can also preset the temperature, humidity and pressure values inside the cabinet 1 through the touch screen.
[0073] It should be noted that touch screens are existing technology disclosed in this field, and their working principle and specific structure will not be described in detail here.
[0074] Specifically, cabinet 1 is provided with a storage cavity and a control cavity, which are separated by a heat insulation plate 12; wherein, the support frame 42 is fixedly installed in the storage cavity; and the processor 6 is located in the control cavity. The above arrangement can prevent the heat generated by the processor 6 during operation from affecting the temperature inside the storage cavity.
[0075] It should be noted that processor 6 is a commonly used processor architecture in this field, and its working principle and specific structure will not be described in detail here.
[0076] Specifically, the bottom of the cabinet 1 is equipped with shock-absorbing pads 11. The shock-absorbing pads 11 can reduce the impact of external vibrations on the specimens inside the cabinet 1 and improve the stability of the cabinet 1.
[0077] For example, in this embodiment, the outer wall material of the cabinet 1 is dark brown or dark brown tempered glass, which facilitates external observation of specimens while preventing external light and ultraviolet radiation. In other embodiments, other materials may be used as the outer wall material of the cabinet 1, and no specific limitation is made here.
[0078] Specifically, the automated specimen storage and retrieval cabinet also includes a camera, which is installed in the storage cavity and is connected to the processor 6. The camera is configured to scan the specimen in each storage position and obtain its 3D model. The 3D model information of each specimen is then transmitted to the processor 6. The processor 6 can match the 3D model of each specimen with the position information of its storage position, so as to control the transfer gripper, locking cylinder, storage and retrieval trolley, transfer trolley 54, lifting drive mechanism 551, transfer trolley 32, and transfer drive mechanism 33 to store and retrieve specimens.
[0079] It should be noted that the above-mentioned camera structure is existing technology disclosed in this field, and its working principle and specific structure will not be described in detail here.
[0080] The method of using the above-mentioned automated specimen retrieval cabinet includes the following steps:
[0081] S1. Place the specimen in the storage position of the storage plate 21.
[0082] In the above steps, the operator first operates the touch screen to slide the retrieval trolley 23 along the retrieval slide rail 22 to move the retrieval plate 21 to the retrieval port. The operator then places the specimen on the storage position of the retrieval plate 21, and the retrieval trolley 23 slides in the opposite direction to move the specimen into the cabinet 1.
[0083] S2. The transfer gripper moves above the storage position and picks up the specimen.
[0084] In the above steps, the transfer trolley 32 and the transfer drive mechanism 33 cooperate with each other, so that while the fixed end of the transfer gripper moves along the first guide rail 31, the first guide rail 31 slides along the second guide rail 34, thereby moving the transfer gripper above the storage position and picking up the specimen.
[0085] S3, the movable plate 51 moves vertically and aligns with the support tray 41.
[0086] In the above steps, when the lifting drive mechanism 551 drives the lead screw 552 to rotate around its own axis, the lifting support 553 drives the movable plate 51 to move along the extension direction of the lead screw 552, so that the movable plate 51 is aligned with the support plate 41 in the horizontal direction.
[0087] S4. The locking cylinder moves along the first horizontal direction to the lug 411, and the movable end of the locking cylinder extends out and into the through hole of the lug 411.
[0088] In the above steps, the transfer trolley 54 moves along the transfer rail 53, moving the fixed end of the locking cylinder to the lug 411, and the movable end of the locking cylinder extends out and into the through hole of the lug 411.
[0089] S5. The locking cylinder retracts along the first horizontal direction and moves the support plate 41 onto the movable plate 51.
[0090] In the above steps, the transfer trolley 54 retracts along the transfer rail 53, and the movable end of the locking cylinder moves the support plate 41 from the support frame 42 to the movable plate 51.
[0091] S6. The movable plate 51 moves vertically and aligns with the access plate 21.
[0092] In the above steps, when the lifting drive mechanism 551 drives the lead screw 552 to rotate around its own axis, the lifting support 553 drives the movable plate 51 to move along the extension direction of the lead screw 552, so that the movable plate 51 is aligned with the access plate 21 in the horizontal direction.
[0093] S7. The transfer gripper places the specimen on the support tray 41.
[0094] S8. The movable plate 51 moves vertically to the original height of the support plate 41.
[0095] In the above steps, the lifting drive mechanism 551, the lead screw 552, and the lifting support 553 cooperate with each other to move the support plate 41 to its original height.
[0096] S9. The locking cylinder moves along the first horizontal direction and moves the support plate 41 to its original position.
[0097] In the above steps, the transfer trolley 54 moves along the transfer rail 53, and the movable end of the locking cylinder moves the support plate 41 from the movable plate 51 to the support frame 42.
[0098] S10, the movable end of the locking cylinder extends out of the through hole of the lug 411.
[0099] It should be noted that the above specimen storage method can be completed by the processor 6 in a fully automatic manner, and the specimen retrieval method is in principle similar to the above specimen storage method. The difference between the specimen retrieval method and the above specimen storage method is that the transfer gripper can place the specimen on the retrieval position of the storage plate 21. The rest of the process will not be described in detail here.
[0100] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
