Among them, an access opening is provided on the side wall of the cabinet body 1; the storage and retrieval device 2 includes a storage and retrieval board 21, the storage and retrieval board 21 is arranged inside the access opening, and the storage and retrieval board 21 is provided with a storage position and a retrieval position; the material transfer device 3 includes a material transfer gripper, and the material transfer gripper is movably arranged in the cabinet body 1 along both the first horizontal direction and the second horizontal direction; the supporting device 4 includes a plurality of supporting trays 41, the plurality of supporting trays 41 are arranged at intervals in the vertical direction in the cabinet body 1, the supporting trays 41 are configured to support specimens, and hanging ears 411 are provided on both sides of the supporting trays 41 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 arranged at an interval from the supporting tray 41, and the position of the movable plate 51 is adjustable in the vertical direction and can be aligned with any one of the storage and retrieval board 21 and the plurality of supporting trays 41 in the first horizontal direction.

The movable ends of the two locking cylinders can respectively extend into the through holes of the two hanging ears 411; the first horizontal direction is perpendicular to the second horizontal direction.

[0061] When a specimen needs to be stored, the specimen is placed at the storage position of the storage and retrieval board 21; the material transfer gripper moves above the storage position and grabs the specimen; the movable plate 51 moves vertically and aligns with the supporting tray 41; the locking cylinder moves horizontally in the first direction to the hanging ear 411, the movable end of the locking cylinder extends out and extends into the through hole of the hanging ear 411; the locking cylinder retracts horizontally in the first direction and drives the supporting tray 41 onto the movable plate 51; the movable plate 51 moves vertically and aligns with the storage and retrieval board 21; the material transfer gripper places the specimen on the supporting tray 41; the movable plate 51 moves vertically to the original height of the supporting tray 41; the locking cylinder moves horizontally in the first direction and drives the supporting 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 a specimen needs to be retrieved, the reverse process of the above steps can be performed. The difference is that finally, the material transfer gripper places the specimen to be retrieved at the retrieval position of the storage and retrieval board 21, and the technician can directly take out the specimen. The automation degree is high, there is no need for the technician to open and close the cabinet door, and the disturbance to the temperature, humidity, pressure in the cabinet and the specimen itself is small.

[0062] It should be noted that a temperature sensor, a temperature regulating mechanism, a humidity sensor, a humidity regulating mechanism, a pressure sensor, and a pressure regulating mechanism are arranged inside the cabinet body 1 to ensure that the automatic specimen storage cabinet can adjust the temperature value, humidity value, and pressure value inside the cabinet body 1 according to the storage environment required by the specimens inside.

[0063] It should be noted that the locking cylinder is specifically a cylinder structure already disclosed in the art, and the material transfer gripper is specifically a gripper structure already disclosed in the art. The working principles and specific structures of both will not be elaborated here.

[0064] Specifically, the supporting device 4 further includes a supporting bracket 42. The supporting bracket 42 is fixedly arranged inside the cabinet body 1. A plurality of supporting trays 41 can all be placed on the supporting bracket 42, and the access board 21 is arranged at the top of the supporting bracket 42. The arrangement of the above-mentioned supporting bracket 42 can support a plurality of supporting trays 41 simultaneously.

[0065] Specifically, the access device 2 further includes an access slide rail 22 and an access trolley. The access trolley is slidably connected to the access slide rail 22. The access slide rail 22 is fixedly connected to the top of the supporting bracket 42 and one end is located at the access opening. The access board 11 is fixedly connected to the top of the access trolley. With the above arrangement, the access trolley can move the access board 11 from the inside of the cabinet body 1 to the access opening, which is more convenient for the operator to take and place specimens.

[0066] Specifically, a plurality of storage positions are arranged on the supporting tray 41, and each storage position can place one specimen. According to the different shapes and volumes of the stored specimens, the specific forms of the storage positions include but are not limited to structures such as grooves and through holes, as long as the stability of the specimen placed on the storage position can be ensured.

[0067] Specifically, the tray moving device 5 further includes two tray moving slide rails 53 and two tray moving trolleys 54. Among them, in the second horizontal direction, the two tray moving slide rails 53 are fixedly connected to both sides of the movable plate 51 in a one-to-one correspondence; the tray moving trolley 54 is slidably connected to the corresponding tray moving slide rail 53, and the fixed end of the locking cylinder is fixedly connected to the tray moving trolley 54, and the tray moving slide rail 53, the tray moving trolley 54 and the locking cylinder are in one-to-one correspondence. With the above arrangement, the tray moving slide rail 53 and the tray moving trolley 54 cooperate with each other to realize the position adjustment of the locking cylinder in the first horizontal direction, and the connection relationship between the structures is simple and the transmission efficiency is high.

[0068] In other embodiments, a mechanical gripper structure commonly used in the art can also be used to realize the position adjustment of the locking cylinder in the first horizontal direction, which is not specifically limited here.

[0069] More specifically, the tray transfer device 5 further includes a lifting assembly 55, and the lifting assembly 55 includes a lifting drive mechanism 551, a lead screw 552, and a lifting support member 553. Among them, the lead screw 552 is disposed in the cabinet 1, the lead screw 552 extends in the vertical direction and passes through the movable plate 51, and one end of the lead screw 552 is fixedly connected to the output end of the lifting drive mechanism 551; the lifting support member 553 is screwed onto the lead screw 552, and the lifting support member 553 supports the bottom of the movable plate 51. When the lifting drive mechanism 551 drives the lead screw 552 to rotate about its own axis, the lifting support member 553 can lift the movable plate 51. The above setting of the lifting assembly 55 can realize the position adjustment of the tray transfer device 5 in the vertical direction, and the connection relationship between the structures is simple, and the transmission efficiency is high.

[0070] Exemplarily, in this embodiment, the lifting support member 553 is detachably connected to the bottom of the movable plate 51 through a bolt structure to ensure the connection strength between the two.

[0071] It should be noted that the lifting drive mechanism 551 is specifically a motor or a motor that can rotate forward and backward commonly used in the art, and its working principle and specific structure will not be elaborated here.

[0072] More specifically, the lifting assembly 55 further includes a spring 554. The lifting support member 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 both ends of the spring 554 are respectively pressed against the first buffer portion 5531 and the second buffer portion 5532. With the above setting, during the lifting process of the lifting support member 553, when the lifting support member 553 suddenly stops, the spring 554 can buffer the inertial effects of the first buffer portion 5531 and the second buffer portion 5532 through its own elastic restoring force, thereby protecting the thread structure of the lead screw 552.

[0073] Exemplarily, in this embodiment, the first buffer portion 5531 is provided with a limiting groove, and the second buffer portion 5532 is provided with a limiting convex. When the first buffer portion 5531 and the second buffer portion 5532 approach each other in the vertical direction, the limiting convex can be inserted into the limiting groove. With the above setting, the limiting groove and the limiting convex cooperate with each other to prevent relative rotation between the first buffer portion 5531 and the second buffer portion 5532 during the lifting process. In other embodiments, the first buffer portion 5531 can also be provided with a limiting convex, and the second buffer portion 5532 can be provided with a limiting groove.

[0074] Specifically, the material transfer device 3 further includes a first guide rail 31 and a material transfer trolley 32. Among them, the first guide rail 31 extends along the first horizontal direction, and the position of the first guide rail 31 is adjustable in the 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 jaw is fixedly arranged on the material transfer trolley 32. With the above settings, the first guide rail 31 and the material transfer trolley 32 cooperate with each other to realize the position adjustment of the material transfer jaw in the first horizontal direction, and the connection relationship between the structures is simple and the transmission efficiency is high.

[0075] More specifically, the material transfer device 3 further includes a material transfer driving mechanism 33 and two second guide rails 34. Among them, the two second guide rails 34 both extend along the second horizontal direction. A sliding connection seat 311 is fixedly arranged at each end of the first guide rail 31, and the two sliding connection seats 311 are slidably connected to the two second guide rails 34 in a one-to-one correspondence. The material transfer driving mechanism 33 is configured to drive the sliding connection seat 311 to move along the second guide rail 34. With the above settings, the material transfer driving mechanism 33 and the second guide rail 34 cooperate with each other. By simultaneously driving the two sliding connection seats 311, the position adjustment of the first guide rail 31 in the second horizontal direction is realized.

[0076] Specifically, the material transfer device 3 further includes a transmission assembly 35. The transmission assembly 35 includes two transmission shafts 351 and two transmission belts 352. Among them, the two transmission shafts 351 are arranged at intervals in the second horizontal direction and both extend along the first horizontal direction. Both ends of the transmission shaft 351 are rotatably arranged on the inner wall of the cabinet body 1; the two transmission belts 352 are both annular. One end of the transmission belt 352 abuts against one of the transmission shafts 351, and the other end abuts against the other transmission shaft 351. The two sliding connection seats 311 are fixedly connected to the two transmission belts 352 in a one-to-one correspondence. When the material transfer driving mechanism 33 drives any one of the transmission shafts 351 to rotate around its own axis, the transmission belt 352 can drive the sliding connection seat 311 to move along the second guide rail 34. With the above settings, the two transmission shafts 351 and the two transmission belts 352 cooperate together. Through the same material transfer driving mechanism 33, the two sliding connection seats 311 can be simultaneously driven to move along the second guide rail 34, with high transmission efficiency, and the two sliding connection seats 311 are in step and will not be misaligned.

[0077] Exemplarily, in this embodiment, the transmission belt 352 has a first section 3521 and a second section 3522 that are connected end to end. The first section 3521 is located above the second section 3522. When the material transfer driving mechanism 33 is turned on, the first section 3521 and the second section 3522 move towards each other. The sliding seat 311 is provided with a limiting hole 3110 that penetrates in the second horizontal direction. The second section 3522 passes through the limiting hole 3110, and the top end of the sliding seat 311 is fixedly connected to the first section 3521. With the above arrangement, the first section 3521 can drive the sliding seat 311 to move along the second guide rail 34. At the same time, the limiting hole 3110 cooperates with the second section 3522 to prevent the sliding seat 311 from tipping over and improve stability.

[0078] Exemplarily, in this embodiment, the material transfer driving mechanism 33 is specifically a motor or a motor that can rotate forward and backward commonly used in the art, and its working principle and specific structure will not be elaborated here.

[0079] Optionally, in other embodiments, the transmission assembly 35 may not be provided. By using a linear motor or a cylinder structure commonly used in the art as the material transfer driving mechanism 33, and setting two material transfer driving mechanisms 33, each material transfer driving mechanism 33 independently drives a sliding seat 311, the technical effect of driving the first guide rail 31 to move in the second horizontal direction by simultaneously driving the sliding seat 311 is also achieved.

[0080] Specifically, the automatic specimen storage and retrieval cabinet further includes a processor 6. The processor 6 is fixedly arranged inside the cabinet body 1, and the processor 6 is respectively communicatively connected to the material transfer gripper, the locking cylinder, the access trolley, the tray transfer trolley 54, the lifting driving mechanism 551, the material transfer trolley 32, the material transfer driving mechanism 33, the temperature sensor, the temperature regulating mechanism, the humidity sensor, the humidity regulating mechanism, the pressure sensor, and the pressure regulating mechanism. With the above arrangement of the processor 6, automatic control of the automatic specimen storage and retrieval cabinet can be realized (such as the automatic storage and retrieval process of specimens and the automatic adjustment of temperature values, humidity values, and pressure values).

[0081] It should be noted that the access trolley, the material transfer trolley 32, and the tray transfer trolley 54 are all trolley structures commonly used in the art, and their working principles and specific structures will not be elaborated here.

[0082] Exemplarily, in this embodiment, the access trolley, the material transfer trolley 32, and the tray transfer trolley 54 are all RULMAN SHN15B. In other embodiments, the access trolley, the material transfer trolley 32, and the tray transfer trolley 54 may also use other types of trolley structures commonly used in the art, and no specific limitation is made here.

[0083] More specifically, the automatic specimen access cabinet further includes a touch screen, which is fixedly connected to the outer wall of the cabinet body 1 and communicatively connected to the processor 6. An operator can take out and store specimens through the touch screen, and can also preset the temperature value, humidity value, and pressure value inside the cabinet body 1 through the touch screen.

[0084] Specifically, the cabinet body 1 is provided with a storage cavity and a control cavity, and the storage cavity and the control cavity are separated by a heat insulation plate 12; among them, the carrier 42 is fixedly arranged in the storage cavity; the processor 6 is located in the control cavity. The above setting can prevent the heat generated during the operation of the processor 6 from affecting the temperature inside the storage cavity.

[0085] It should be noted that the processor 6 is a commonly used processor structure in the art, and its working principle and specific structure will not be elaborated here.

[0086] Specifically, shock-absorbing foot pads 11 are arranged at the bottom of the cabinet body 1. The setting of the shock-absorbing foot pads 11 can reduce the influence of external vibration on the specimens inside the cabinet body 1 and improve the stability of the cabinet body 1.

[0087] Exemplarily, in this embodiment, the material of the outer wall of the cabinet body 1 is dark brown or dark brown tempered glass, which is convenient for observing specimens externally and can also prevent external light and ultraviolet rays. In other embodiments, other materials can also be used as the material of the outer wall of the cabinet body 1, which will not be specifically limited here.

[0088] Specifically, the automatic specimen access cabinet further includes a camera, which is arranged in the storage cavity and communicatively connected to the processor 6. The camera is configured to scan the specimens on each storage position and obtain their 3D models, and then transmit the 3D model information of each specimen to the processor 6. The processor 6 can correspond the 3D model of each specimen with the position information of its corresponding storage position, so as to control the material transfer gripper, locking cylinder, access trolley, transfer tray trolley 54, lifting drive mechanism 551, material transfer trolley 32, and material transfer drive mechanism 33 to store and take out specimens.

[0089] It should be noted that the above camera structure is an existing technology disclosed in the art, and its working principle and specific structure will not be elaborated here.

[0090] The present invention also provides a specimen storage method, which uses the above automatic specimen access cabinet and includes the following steps:

[0091] S1. Place the specimen at the storage position of the access plate 21.

[0092] In the above steps, the operator first operates the touch screen to slide the access trolley 23 along the access rail 22 to move the access plate 11 to the access port. The operator then places the specimen on the storage position of the access plate 21, and the access trolley 23 slides in the opposite direction to move the specimen to the interior of the cabinet 1.

[0093] S2. The material transfer clamp moves to the top of the material storage position and clamps the specimen.

[0094] In the above steps, the material transfer trolley 32 cooperates with the material transfer drive mechanism 33 so that the fixed end of the material transfer clamp moves along the first guide rail 31 while the first guide rail 31 slides along the second guide rail 34, thereby moving the material transfer clamp to above the material storage position and clamping the specimen.

[0095] S3 , the movable plate 51 moves in the vertical direction and is aligned with the receiving tray 41 .

[0096] In the above steps, when the lifting drive mechanism 551 drives the lead screw 552 to rotate around its own axis, the lifting support member 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 tray 41 in the horizontal direction.

[0097] S4. The locking cylinder moves along the first horizontal direction to the hanging ear 411 , and the movable end of the locking cylinder extends out and into the through hole of the hanging ear 411 .

[0098] In the above steps, the tray moving trolley 54 moves along the tray moving rail 53 to move the fixed end of the locking cylinder to the hanging ear 411 , and the movable end of the locking cylinder extends out and into the through hole of the hanging ear 411 .

[0099] S5 , the locking cylinder retreats along the first horizontal direction and drives the supporting tray 41 to the movable plate 51 .
