[0014] A working method of a constant temperature storage device for gene testing samples, the specific operating steps of the working method are as follows: Step 1: When storing and retrieving genetic testing samples, the transfer is performed through the transfer mechanism, and the box door outside the transfer box is opened by the third electric push rod. At this time, the test tube containing the genetic testing sample is inserted into the ring seat of the second installation component. During the installation process, the test tube acts on the movable clamp to compress the second spring in the inner cavity until the movable clamp clamps the outer wall of the test tube under the action of the second spring. At this time, the turntable is driven to rotate by the fifth motor to realize the rotation of the storage space, and then the test tube is installed in the second installation component with different storage spaces. At this time, the box door outside the transfer box is closed, and the transfer mechanism is placed on the lifting platform. The first motor works and the first synchronous wheel drives the first threaded rod to rotate, thereby realizing the lifting and lowering of the lifting platform and the transfer mechanism, and the box door inside the transfer box corresponds to the cavity door of the storage cavity.

At this time, the electric turntable of the material moving mechanism works to realize the rotation of the second electric push rod, and the position of the electric clamp is adjusted. The electric clamp is driven to rise and fall by the second electric push rod to achieve height adjustment. The second threaded rod is driven to rotate by the fourth motor, and cooperates with the first threaded sleeve rod connected by thread to realize the translation of the electric clamp. The test tube is clamped by the electric clamp. With the rotation of the turntable and the movement of the carrier, the test tube in the transfer mechanism is placed in the first mounting assembly of the carrier in sequence. At the same time, the transfer mechanism is corresponded to different storage cavities through the lifting platform and the lifting of the transfer mechanism, and the transfer mechanism and the test tubes in different storage cavities are stored. The temperature in the storage cavity is sensed by the first temperature sensor, and the storage cavity is cooled by the cold air pipe to ensure that the storage temperature is appropriate. Step three: when taking out the test tube from the storage cavity, the transfer mechanism is first matched with the storage cavity, the test tube to be taken is moved to the position close to the material transfer mechanism through the circulation storage mechanism, the test tube is transferred from the first installation component to the second installation component of the transfer mechanism through the material transfer mechanism, and the lifting and lowering of the transfer mechanism and the rotation of the turntable make it easy to match different storage spaces with different storage cavities, and then store different test tubes in different storage spaces. When it is necessary to take out the test tube from the storage space, the turntable rotates to move the storage space to correspond to the inlet and outlet slots on the outside of the transfer box, and then the test tube is taken out.

The third threaded rod is driven to rotate by the sixth motor, and then the lifting plate and the plate arm are driven to descend by the second threaded sleeve rod connected by thread. When the pressure plate contacts the top side of the test tube, the plate arm continues to descend, and the fixed rod is gradually retracted into the movable rod sleeve to compress the first spring. The matching length of the fixed rod and the movable rod sleeve is adjusted by the elastic deformation of the first spring to limit the top of the test tube.

At this time, the test tubes are transferred between different storage cavities and different storage spaces by the material transfer mechanism, which is convenient for the subsequent storage and retrieval of the test tubes in the storage space of the transfer mechanism, avoiding the temperature imbalance in the storage cavity during the storage and retrieval of the test tubes, affecting the preservation of the test tubes, and avoiding the operator's hands directly entering the storage cavity to retrieve the test tubes during the storage and retrieval, thereby reducing the risk of contamination; The transfer mechanism plays the role of test tube transfer. At the same time, it cools the test tubes through the semiconductor refrigeration sheet in the storage space and monitors the temperature through the second temperature transmitter, so as to realize the separate storage and temperature control of the test tubes in each storage space, and facilitate the classified storage and transportation of test tubes with different storage and insulation requirements through the transfer mechanism. The top of the test tube is limited by the contact between the pressure plate and the top side of the test tube, and cooperates with the second installation component to ensure that the test tube is firmly fixed in the storage space during the transportation process. The fixed rod is elastically connected to the movable rod sleeve, so that test tubes of different heights can be fixed in different storage spaces. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the test tube containing the gene detection sample is inserted into the ring seat (62) of the second installation component (50). During the installation process, the test tube acts on the movable clamping block (65) to compress the second spring (64) in the inner cavity (63) until the movable clamping block (65) clamps the outer wall of the test tube under the action of the second spring (64). At this time, the turntable (48) is driven to rotate by the fifth motor (47) to realize the rotation of the storage space, thereby The test tube is installed in a second installation assembly (50) of a different storage space. At this time, the box door (46) on the outside of the transfer box (42) is closed, and the transfer mechanism (13) is placed on the lifting platform (11). The first motor (17) is operated, and the first synchronous wheel (16) is driven to realize the rotation of the first threaded rod (14), thereby realizing the lifting of the lifting platform (11) and the transfer mechanism (13). The box door (46) on the inside of the transfer box (42) is matched with the chamber door (8) of the storage chamber (2). At this time, the box door (46) on the inside of the transfer box (42) is opened, and at the same time, the first electric push rod (9) realizes the opening of the chamber door (8); Step 2: The second motor (28) is operated to rotate the second synchronous wheel (25) to realize the transmission of the synchronous belt (26), and the object carrier (20) is driven to move on the circular track (19) through the connecting block (27) and the connecting seat (22), and the position of the object carrier (20) and the first mounting assembly (21) is adjusted. The third motor (29) is operated to drive the rotating shaft (30) to rotate, and the rotating rod (31) is used to clamp the roller (32) into the limiting groove (24) of the limiting seat (23) to achieve limiting. At this time, the electric turntable (33) of the material transfer mechanism (4) is operated to realize the rotation of the second electric push rod (34), and the position of the electric clamping claw (39) is adjusted. The electric clamping claw (39) is driven to rise and fall by the second electric push rod (34) to achieve height adjustment. The machine (40) drives the second threaded rod (41) to rotate, and cooperates with the threaded first threaded sleeve rod (36) to achieve translation of the electric clamp (39), and clamps the test tube through the electric clamp (39). As the turntable (48) rotates and the carrier (20) moves, the test tubes in the transfer mechanism (13) are sequentially placed in the first mounting assembly (21) of the carrier (20). At the same time, the transfer mechanism (13) is made to correspond to different storage chambers (2) through the lifting platform (11) and the transfer mechanism (13). The transfer mechanism (13) and the test tubes in different storage chambers (2) are stored. The temperature in the storage chamber (2) is sensed by the first temperature sensor (5), and the storage chamber (2) is cooled by the cold air pipe (6) to ensure that the storage temperature is appropriate. Step 3: When taking out a test tube from the storage chamber (2), the transfer mechanism (13) is first matched with the storage chamber (2), and the test tube to be taken is moved to a position close to the material transfer mechanism (4) through the circulation storage mechanism (3). The test tube is transferred from the first installation component (21) to the second installation component (50) of the transfer mechanism (13) through the material transfer mechanism (4). The transfer mechanism (13) is raised and lowered and the turntable (48) is rotated to make different storage spaces correspond to different storage chambers (2), and different test tubes are stored in different storage spaces. When it is necessary to take out a test tube from the storage space, the turntable (48) is rotated to move the storage space to correspond to the inlet and outlet slot (44) on the outside of the transfer box (42), and then the test tube is taken out. (13) During transportation, cooling is performed by the semiconductor refrigeration plate (51) in the storage space, and temperature monitoring is performed by the second temperature transmission device (52), so that each storage space can store the test tube separately and control the temperature.

When the pressing plate (60) contacts the top side of the test tube, the plate arm (57) continues to descend, and the fixed rod (58) is gradually retracted into the movable rod sleeve (59) to compress the first spring (61). The matching length of the fixed rod (58) and the movable rod sleeve (59) is adjusted by the elastic deformation of the first spring (61), so as to limit the top of the test tube.
