Detailed implementation manners

[0062] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0063] The test tube rack transfer and storage device of the present invention can adapt to test tube racks 6 of different shapes and specifications, and complete the transfer and storage of various test tube racks 6 in the production line, effectively improving the compatibility and adaptability of the test tube rack automatic storage device.

[0064] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the test tube rack transfer and storage device includes a machine platform chassis 1, a storage component 2, a transfer component 3 and a test tube rack access component 4. The storage component 2 is arranged on the machine platform chassis 1. The storage component 2 is formed with a plurality of storage positions 201, and each storage position 201 is formed with a jacking groove 202. The transfer component 3 is arranged on the machine platform chassis 1. The transfer component 3 is used to receive the test tube racks 6 sent out from each processing node or storage position 201, or transfer the test tube racks 6 to the storage position 201 or each processing node. The test tube rack access component 4 includes a connecting seat 41, a jacking component 42 and an access component 43. The connecting seat 41 is slidably connected to the machine platform chassis 1. The jacking component 42 is connected to the connecting seat 41. The access component 43 is rotatably connected to the jacking component 42. The access component 43 is used to send the test tube rack 6 into or out of the storage position 201. The access component 43 is formed with a receiving portion 431. The jacking component 42 is used to drive the access component 43 to move up and down, so that the receiving portion 431 protrudes from the jacking groove 202, or sinks from the jacking groove 202.

[0065] The test tube rack transfer and storage device provided in this embodiment can be used for the transfer and buffer storage of the test tube rack 6 between any two adjacent processing nodes of the test tube rack production line. Among them, the transfer component 3 can transfer the test tube rack 6 among the previous processing node, the storage position 201 and the subsequent processing node.

[0066] During the process of the transfer component 3 sending the test tube rack 6 to the storage position 201, the jacking component 42 can be driven to drive the access component 43 to move upward, so that the receiving portion 431 of the access component protrudes from the jacking groove 202, so that the receiving portion 431 can contact the bottom of the test tube rack 6. Subsequently, the access component 43 is driven to realize sending the test tube rack 6 into the interior of the storage position 201. After the test tube rack 6 is in place, the jacking component 42 drives the access component 43 to sink from the jacking groove 202, so that the receiving portion 431 is separated from the test tube rack 6, and the feeding action of the test tube rack 6 is completed.

[0067] When it is necessary to transfer the test tube rack 6 out of the storage position 201, the lifting component 42 also drives the access component 43 to move towards the lifting groove 202, so that the receiving portion 431 of the access component 43 contacts the bottom of the test tube rack 6, and the test tube rack 6 is lifted from the storage position 201. And after the transfer component 3 approaches the corresponding storage position 201, the access component 43 is driven to send the test tube rack 6 out of the storage position 201 to the transfer component 3, completing the sending action of the test tube rack 6.

[0068] Therefore, after the test tube rack 6 is lifted by the liftable access component 43, the access component 43 is used to complete the access action of the test tube rack 6 in the storage position 201. The receiving portion 431 only needs to contact the bottom of the test tube rack 6, without forming a specific structure according to the shapes of different test tube racks 6, enabling the automatic storage device of the test tube rack 6 to adapt to and be compatible with test tube racks 6 of different shapes and specifications, and completing the transfer and storage of multiple test tube racks 6 in the pipeline, effectively improving the compatibility and adaptability of the automatic storage device of the test tube rack 6.

[0069] In addition, when the test tube rack 6 is sent into or out of the storage position 201, since the access component 43 lifts the test tube rack 6, there will be no friction between the bottom of the test tube rack 6 and the inner bottom surface of the storage position 201, thereby increasing the transfer speed when the test tube rack 6 is sent into or out of the storage position 201, effectively improving the transfer efficiency of the test tube rack 6, and at the same time avoiding the problem that the test tube rack 6 cannot be transferred in place due to the influence of friction, and improving the transfer stability of the test tube rack 6.

[0070] In this embodiment, as Figures 6 to 8 shown, the lifting component 42 includes a first driving member 421 and a lifting plate 424. The first driving member 421 is arranged on the connecting seat 41. The output shaft of the first driving member 421 is rotatably connected to a rotating member 422, and the rotating member 422 is formed with a convex portion 423. The lifting plate 424 is slidably connected to the connecting seat 41, and the lifting plate 424 is connected to the convex portion 423. The access component 43 is rotatably arranged on the lifting plate 424. The first driving member 421 drives the lifting plate 424 to move up and down through the rotating member 422 to drive the access component 43 to move up and down.

[0071] The first driving member 421 drives the rotating member 422 to rotate, so that the convex portion 423 rotates around the center of the rotating member 422. Under the combined movement of the convex portion 423 and the lifting plate 424, the rotational movement of the rotating member 422 is converted into the lifting movement of the lifting plate 424 on the connecting seat 41 to drive the access component 43 to move up and down, realizing the protrusion of the receiving portion 431 from the lifting groove 202, or the sinking of the receiving portion 431 from the lifting groove 202, so that the access component 43 can complete the feeding action and the sending action of the test tube rack 6.

[0072] Preferably, the first driving member 421 is a stepping motor.

[0073] Specifically, in order to ensure that the rotational motion of the rotating member 422 is converted into the lifting motion of the lifting plate 424, as shown in FIG. Figure 6 and Figure 7 As shown, the connecting seat 41 is provided with a vertical guide rail 411, and the lifting plate 424 is slidably connected to the vertical guide rail 411 through a slider. The outer protrusion 423 is an eccentric boss disposed on the side of the rotating member 422 away from the first driving member 421, and the lifting plate 424 is formed with a strip slide 425, the eccentric boss is slidably connected to the strip slide 425, and a preset angle is formed between the strip slide 425 and the vertical guide rail 411, and the preset angle is greater than 0°. Then, when the eccentric boss rotates with the rotating member 422, the eccentric boss slides in the strip slide 425, thereby pushing the lifting plate 424 to move along the vertical guide rail 411, realizing the conversion of the rotational action of the rotating member 422 into the lifting and lowering motion of the lifting plate 424.

[0074] In this embodiment, the strip-shaped slide groove 425 is preferably a horizontal groove, that is, the preset angle between the strip-shaped slide groove 425 and the vertical guide rail 411 is 90°.

[0075] Of course, in addition to setting the outer protrusion 423 as an eccentric boss, the rotating member 422 can also be set as a cam structure, and the strip slide groove 425 contacts the outer contour of the cam, so that the outer contour of the cam cooperates with the strip slide groove 425 to realize the conversion of the rotating movement of the rotating member 422 into the lifting movement of the lifting plate 424.

[0076] Furthermore, if Figure 6 As shown, the connection seat 41 is provided with a vertical guide block 412, a vertical limit groove is arranged in the vertical guide block 412, and the lifting plate 424 is formed with a guide rib 426, and the guide rib 426 is slidably connected to the vertical limit groove. When the lifting plate 424 rises or falls on the connection seat 41, the vertical limit groove guides the guide rib 426, and the stability of the lifting movement of the lifting plate 424 can be further improved.

[0077] In this embodiment, Figure 6 and Figure 8As shown, the inlet / outlet component 43 includes a second driving member 432 and a first transmission member 433. The second driving member 432 is disposed on the connecting seat 41, the first transmission member 433 is rotatably connected to the second driving member 432, and the first transmission member 433 is driven along the length direction of the storage position 201; the receiving portion 431 is the top surface of the first transmission member 433. Further, when the transfer member 3 sends the test tube rack 6 to the storage position 201, the lifting component 42 drives the second driving member 432 and the first transmission member 433 to move upward, so as to receive the test tube rack 6 by using the top surface of the first transmission member 433; and driven by the second driving member 432, the first transmission member 433 drives the test tube rack 6 to move into the storage position 201, realizing the feeding of the test tube rack 6 into the storage position 201. When sending the test tube rack 6 out of the storage position 201, under the action of the lifting component 42, the first transmission member 433 lifts the test tube rack 6 in the storage position 201, and driven by the second driving member 432, the first transmission member 433 moves the test tube rack 6 out of the storage position 201, completing the sending action of the test tube rack 6.

[0078] The first transmission member 433 is one or more of a conveyor belt group, a conveyor chain group or a gear rack group, and can be selected and set according to actual requirements.

[0079] In this embodiment, as Figure 8 shown, the first transmission member 433 is preferably a conveyor belt group, specifically including a cylindrical conveyor belt, a driving wheel and three driven wheels. The driving wheel and the driven wheels are all rotatably connected to the lifting plate 424. The driving wheel is rotatably connected to the output shaft of the second driving member 432, and the driving wheel and the driven wheels are connected by the cylindrical conveyor belt. Two of the driven wheels are conveying wheels, and the two conveying wheels are on the same horizontal plane. The cylindrical conveyor belt between the two conveying wheels serves as the receiving portion 431 of the test tube rack 6 to send the test tube rack 6 into or out of the storage position 201. The other driven wheel is a steering wheel. The driving wheel is located below the conveying wheels, and the steering wheel is located between the driving wheel and the conveying wheels. The steering wheel is used to change the conveying direction of the conveyor belt between the driving wheel and the conveying wheels to improve the running stability of the conveyor belt group.

[0080] On the other hand, since the actual transfer directions of the test tube rack 6 are different at each processing node of the test tube rack production line, the test tube rack 6 needs to be additionally adjusted by an external device for its traveling direction before being transferred to the transfer member 3, resulting in an increase in the transfer time of the test tube rack production line and affecting the working efficiency of the production line.

[0081] In an embodiment of the present invention, as Figures 3 to 5As shown in the figure, the transfer component 3 includes a carrier seat 31, an angle adjustment member 32, and a transfer assembly 33. The carrier seat 31 is slidably connected to the machine base chassis 1, the angle adjustment member 32 is rotatably connected to the carrier seat 31, and the transfer assembly 33 is disposed above the angle adjustment member 32. The transfer assembly 33 includes a third driving member 332 and a second transmission member 331. The third driving member 332 is disposed on the angle adjustment member 32, and the second transmission member 331 is rotatably connected to the third driving member 332. The second transmission member 331 is driven along the length direction of the storage position 201. By driving the second transmission member 331 to be driven along the length direction of the storage position 201 by the third driving member 332, the test tube rack 6 can be transferred above the second transmission member 331, or the test tube rack 6 can be sent out from the second transmission member 331. The angle adjustment member 32 is used to drive the second transmission member 331 to rotate to adjust the position angle of the second transmission member 331.

[0082] It can be understood that by arranging the angle adjustment member 32 between the second transmission member 331 and the carrier seat 31, the second transmission member 331 can have a rotational movement dimension above the carrier seat 31. Furthermore, when the transfer component 3 transfers the test tube rack 6 from the processing node to the storage position 201, or from the storage position 201 to the processing node, the angle adjustment member 32 can be used to adjust the position angle of the second transmission member 331 in real time, so that the placement angle of the test tube rack 6 corresponds to the traveling direction of the test tube rack 6 at the processing node, or the placement direction of the test tube rack 6 at the storage position 201, thereby shortening the transfer time of the test tube rack 6 in the pipeline and effectively improving the working efficiency of the transfer and storage of the test tube rack 6.

[0083] In addition, since the test tube rack transfer and storage device can adapt to the traveling directions of the test tube racks 6 at different processing nodes in the pipeline, there is no need to arrange equipment for adjusting the direction of the test tube rack 6 in the pipeline, effectively reducing the site space occupied by the pipeline and improving the space utilization rate of the test tube rack pipeline.

[0084] It should also be noted here that since the transfer component 3 transfers from the processing node of the test tube rack pipeline to the storage position 201, or from the storage position 201 to the transfer node, and the placement direction of the test tube rack 6 at the storage position 201 and the traveling directions of the test tube racks 6 at each processing node are all at fixed angles, the rotation angle of the angle adjustment member 32 is a specific angle, and the specific angle is determined by the traveling direction of the test tube rack 6 at the processing node and the placement direction of the test tube rack 6 at the storage position 201 to ensure adaptation to the traveling direction of the test tube rack 6 at the processing node, or the placement direction of the test tube rack 6 at the storage position 201.

[0085] For example, when the traveling direction of the test tube rack 6 in the processing node of the pre-processing is at an angle A, the placement direction of the test tube rack 6 at the storage position 201 is at an angle B, and the included angle between the angle A and the angle B is 90°, during the process of transferring the test tube rack 6 from the pre-processing to the storage position 201 by using the second transmission member 331, the rotation angle of the angle adjusting member 32 is 90°.

[0086] When the traveling direction of the test tube rack 6 in the pre-inspection buffer position is at an angle C, and the included angle between the angle C and the angle B is 45°, during the process of transferring the test tube rack 6 from the storage position 201 to the pre-inspection buffer position by using the second transmission member 331, the rotation angle of the angle adjusting member 32 is 45°.

[0087] Specifically, to improve the rotation stability of the transfer assembly 33 and the test tube rack 6 above the transfer assembly 33, the angle adjusting member 32 can be arranged in the following ways:

[0088] The first arrangement method is as Figure 3 shown. The angle adjusting member 32 includes a fourth driving member 321 and a turntable 322. The fourth driving member 321 is connected to the bearing seat 31 and is rotationally connected to the turntable 322. The turntable 322 is provided with an installation shell 323. The third driving member 332 is installed in the installation shell 323, and the second transmission member 331 is rotationally connected to the installation shell 323. By driving the turntable 322 to rotate through the fourth driving member 321, the installation shell 323 and the second transmission member 331 are driven to rotate, so as to realize the corresponding adjustment of the position angle of the second transmission member 331 according to the traveling direction of the test tube rack 6 in the processing node or the placement direction of the test tube rack 6 at the storage position 201. At the same time, by using the cooperation of the fourth driving member 321 and the turntable 322, the accuracy of controlling the rotation angle of the second transmission member 331 is improved, ensuring that the second transmission member 331 can accurately face the equipment at the storage position 201 or the processing node, and improving the transfer stability of the test tube rack 6.

[0089] The second arrangement method: The angle adjusting member 32 includes a fourth driving member 321, a driving gear and a driven gear. The driving gear and the driven gear are meshed with each other. The fourth driving member 321 is connected to the driving gear, and the driven gear is connected to the transfer assembly 33 through the installation shell 323. By driving the driving gear and the driven gear to rotate through the fourth driving member 321, the installation shell 323 and the transfer assembly 33 are correspondingly driven to rotate, so as to realize the adaptive adjustment of the position angle of the second transmission member 331. And by using the cooperation of the fourth driving member 321 and the gear set, the accuracy of controlling the rotation angle of the second transmission member 331 can also be improved, thereby improving the transfer stability of the test tube rack 6.

[0090] In this embodiment, the arrangement method of the angle adjusting member 32 preferably adopts the first arrangement method to simplify the structure of the angle adjusting member 32 for easy installation and maintenance.

[0091] Preferably, the fourth driving member 321 is a stepper motor. The stepper motor is mounted below the bearing seat 31 through a connecting bracket, and the output shaft of the stepper motor is connected to the lower rotating shaft of the turntable 322 through a coupling to drive the angle adjusting member 32 to rotate.

[0092] It should also be noted that when the second transmission member 331 receives the test tube rack 6 or sends out the test tube rack 6 from the second transmission member 331, the self-weight of the test tube rack 6 will act alone on one end of the second transmission member 331. To prevent the second transmission member 331 from tilting due to unbalanced force, as Figure 3 and Figure 4 shown, the bearing seat 31 is provided with a plurality of anti-tilting blocks 311. The plurality of anti-tilting blocks 311 are arranged in a circular pattern around the installation shell 323, and the anti-tilting blocks 311 are formed with a horizontal limiting groove 312 facing the installation shell 323. The installation shell 323 is formed with an anti-tilting convex portion 324. The anti-tilting convex portion 324 extends along the transmission direction of the second transmission member 331, and the anti-tilting convex portion 324 is slidably clamped with two opposite anti-tilting blocks 311.

[0093] Furthermore, when the second transmission member 331 receives the test tube rack 6 or sends out the test tube rack 6 from the second transmission member 331, and one end of the second transmission member 331 bears the self-weight of the test tube rack 6, the lower bottom surface of the horizontal limiting groove 312 of the anti-tilting convex portion 324 on the same side as the test tube rack 6 can be used to cooperate with the anti-tilting block 311 to provide an upward supporting force for the installation shell 323. At the same time, the upper bottom surface of the horizontal limiting groove 312 of the anti-tilting convex portion 324 on the side opposite to the test tube rack 6 is used to cooperate with the anti-tilting block 311 to provide a downward pressure for the installation shell 323. Furthermore, the cooperation of the two groups of anti-tilting convex portions 324 and anti-tilting blocks 311 is used to balance the acting force of the test tube rack 6 on one side of the second transmission member 331, thereby effectively preventing the second transmission member 331 from tilting under the influence of the gravity of the test tube rack 6, and further ensuring the stability when the turntable 322 drives the installation shell 323 and the second transmission member 331 to rotate.

[0094] It should be noted that, as Figure 4 shown, the anti-tilting convex portion 324 can be a rib structure formed on two opposite side surfaces of the installation shell 323, and the rib structure is located below the first transmission member 433, so as to use the two relatively arranged rib structures to cooperate with the anti-tilting blocks 311 to balance the self-weight of the test tube rack 6.

[0095] In other embodiments, the anti-tilting convex portion 324 can also be a strip structure formed on the bottom of the installation shell 323. The strip structure is located below the first transmission member 433, and both ends of the strip protrude from two opposite side surfaces of the installation shell 323, so as to use both ends of the strip to cooperate with the anti-tilting blocks 311 to balance the self-weight of the test tube rack 6.

[0096] In this embodiment, the second transmission member 331 is located below the access assembly 43. When the second transmission member 331 sends the test tube rack 6 to the storage position 201, the test tube rack 6 will not be blocked by the storage rack and fall outside the storage position 201, ensuring the accuracy of the transmission of the test tube rack 6 between the second transmission member 331 and the storage position 201.

[0097] The second transmission member 331 is one or more of a conveyor belt group, a conveyor chain group, or a gear and rack group, and can be selected and set according to the actual use scenario.

[0098] In this embodiment, as Figure 5 shown, the second transmission member 331 is a conveyor belt group, which specifically includes a conveyor belt, a driving wheel, and four driven wheels. The driving wheel is rotatably connected to the output shaft of the second driving member 432, and the driving wheel and the driven wheels are connected by a conveyor belt. Two of the driven wheels are conveying wheels, and the two conveying wheels are located on the same horizontal plane, and the tops of the two conveying wheels are above the bottom surface of the storage position 201 to ensure the accuracy when the conveyor belt sends the test tube rack 6 to the storage position 201. The driving wheel is located below the driven wheels, and the other two driven wheels are turning wheels and are located between the conveying wheels and the driving wheel. The two turning wheels are used to change the conveying direction of the conveyor belt between the driving wheel and the conveying wheels, improving the running stability of the conveyor belt group.

[0099] In this embodiment, as Figure 3 shown, a test tube rack stopper 325 is provided at the top of the mounting shell 323. An opening is formed at the top of the test tube rack stopper 325, and the second transmission member 331 is located below the opening to form a stop edge by the side wall surfaces of the opening, realizing the stop and limit of the side wall surface of the test tube rack 6, and avoiding the tilting phenomenon of the test tube rack 6 when the second transmission member 331 drives the test tube rack 6 to move, further improving the conveying stability of the test tube rack 6.

[0100] In an embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 10 shown, the storage component 2 includes a support frame 21 and a plurality of test tube rack partitions 22. The support frame 21 is arranged on the machine table chassis 1, and a plurality of test tube rack partitions 22 are arranged at intervals on the support frame 21. A storage position 201 is formed between any two adjacent test tube rack partitions 22. The test tube rack partitions 22 can guide and support the test tube rack 6 to improve the transfer stability when the test tube rack 6 is sent into the storage position 201 and when the test tube rack 6 is sent out of the storage position 201.

[0101] It should be noted that the number of test tube rack partitions 22 arranged above the support frame 21 can be determined according to the number of test tube racks 6 to be cached in different processing nodes.

[0102] It should also be noted that the storage position 201 is provided with a first detection member 23 and a second detection member 24. The first detection member 23 is located inside the storage position 201 and is used to detect the in-place situation of the test tube rack 6 inside the storage position 201; the second detection member 24 is located at the entrance of the storage position 201 and is used to detect whether the test tube rack 6 is sent out of the storage position 201.

[0103] Specifically, the first detection member 23 can be a contact sensor. The first detection member 23 is fixed to the inner wall surface of the storage rack. During the process of the test tube rack 6 being sent into the storage position 201, when the test tube rack 6 contacts the first detection member 23, it indicates that the test tube rack 6 has been completely sent into the storage position 201. At this time, the second driving member 432 and the third driving member 332 receive signals and stop operating simultaneously, so that the first transmission member 433 and the second transmission member 331 stop operating, completing the feeding action of the test tube rack 6.

[0104] The second detection member 24 can be an infrared sensor. The second detection member 24 is fixed to the side of the storage rack facing the rotary transfer member 3, and the detection unit of the second detection member 24 faces the storage position 201. By using whether the second detection member 24 senses the test tube rack 6, it can be determined whether the test tube rack 6 is sent out of the storage position 201. When the second detection member 24 detects that the test tube rack 6 has been completely sent out of the storage position 201, the second driving member 432 and the third driving member 332 stop operating simultaneously, so that the first transmission member 433 and the second transmission member 331 stop operating, completing the sending-out action of the test tube rack 6.

[0105] In the embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 9 shown, the test tube rack transfer and storage device further includes two sets of translation components 5. The translation component 5 includes a fifth driving member 51, a third transmission member 52 and a transfer guide rail 53. The fifth driving member 51 is arranged on the machine table chassis 1, the third transmission member 52 is rotatably connected to the fifth driving member 51, the bearing seat 31 is slidably connected to the third transmission member 52 in one set of translation components 5, the connecting seat 41 is slidably connected to another third transmission member 52, and the third transmission member 52 is driven along the arrangement direction of a plurality of storage positions 201. The transfer guide rail 53 is arranged on the machine table chassis 1, and the support seat and the connecting seat 41 are respectively slidably connected to the corresponding transfer guide rail 53.

[0106] By driving the third transmission member 52 to drive through the fifth driving member 51, driving the connecting seat 41 and the bearing seat 31 to slide on the machine table chassis 1 along the arrangement direction of a plurality of storage positions 201, the transfer member 3 and the test tube rack inlet and outlet member 4 are driven to move between a plurality of storage positions 201, improving the flexibility of storing the test tube rack 6.

[0107] Among them, the fifth driving member 51 is a stepping motor, and the third transmission member 52 is a conveyor belt group. The length of the transfer guide rail 53 can be correspondingly extended or compressed according to the number of test tube racks 6 at each processing node in the test tube rack production line, or the transmission distance between two adjacent processing nodes, or other actual situations, without being limited by the number of storage areas, further improving the flexibility of storing the test tube racks 6.

[0108] Correspondingly, as Figures 11 to 14 shown, the present invention also provides a method for transferring and caching test tube racks, where the method for transferring and caching test tube racks is based on the test tube rack transfer and storage device described in any one of the above embodiments. The method for transferring and caching test tube racks includes the following steps:

[0109] S1, load the test tube rack 6 onto the transfer member 3, and through the transfer member 3, direct the test tube rack 6 towards the storage position 201.

[0110] S2, drive the lifting assembly 42 to drive the access assembly 43 to move upward, so that the receiving portion 431 of the access assembly 43 protrudes from the lifting slot 202.

[0111] S3, drive the transfer member 3 to drive the test tube rack 6 to move towards the storage position 201, and make the receiving portion 431 abut against the test tube rack 6; at the same time, drive the access assembly 43 to send the test tube rack 6 into the storage position 201.

[0112] S4, drive the lifting assembly 42 to drive the access assembly 43 to move downward, so that the receiving portion 431 disengages from the test tube rack 6, completing the feeding action of the test tube rack 6.

[0113] S5, determine that it is necessary to send the test tube rack 6 out of the storage position 201, drive the lifting assembly 42 to drive the access assembly 43 to move upward, so that the receiving portion 431 abuts against the test tube rack 6.

[0114] S6, drive the access assembly 43 and the transfer member 3 to send the test tube rack 6 out of the storage position 201.

[0115] S7, drive the lifting assembly 42 to drive the access assembly 43 to move downward, completing the sending action of the test tube rack 6.

[0116] According to the test tube rack transfer and buffer method of this embodiment, the lifting assembly 42 drives the access assembly 43 to move upward or downward, correspondingly realizing the lifting movement of the access assembly 43, so as to use the receiving portion 431 of the access assembly 43 to abut against the bottom of the test tube rack 6 and send it into the storage position 201, completing the feeding action of the test tube rack 6; or lift the test tube rack 6 from the storage position 201 and send it out from the storage position 201, completing the access action of the test tube rack 6. Furthermore, during the process of the test tube rack 6 entering and exiting, only the receiving portion 431 of the access assembly 43 needs to contact the test tube rack 6, without the need to prepare specific access structures for test tube racks 6 of different shapes and specifications, realizing the compatibility of the transfer of test tube racks 6 with different structures, and there is no need to reconfigure the access structure when transferring different test tube racks 6, improving the flexibility and transfer and storage efficiency of the test tube rack 6 transfer process.

[0117] It should be noted that in step S1, when using the transfer component 3 to receive the test tube rack 6 at the processing node of the test tube rack 6, the fifth driving member 51, the third transmission member 52 and the transfer guide rail 53 connected below the carrier seat 31 can be used in cooperation to move the transfer component 3 towards the processing node; and during the transfer process of the transfer component 3 towards the processing node, the driving angle adjusting member 32 drives the second transmission member 331 to rotate a certain angle, so that the orientation direction of the second transmission member 331 is consistent with the transfer movement direction of the test tube rack 6 in the processing node, so as to use the second transmission member 331 to receive the test tube rack 6 at the processing node.

[0118] And during the process of the fifth driving member 51 and the third transmission member 52 cooperating to transfer the transfer component 3 to the storage position 201, the angle adjusting member 32 can be used to drive the second transmission member 331 to rotate, so that the orientation direction of the second transmission member 331 is consistent with the placement direction of the test tube rack 6 in the storage position 201, ensuring that the test tube rack 6 faces the storage position 201, so as to send the test tube rack 6 into the storage position 201.

[0119] It should also be noted that step S1 and step S2 can be carried out synchronously, that is, during the process of the transfer component 3 transferring the test tube rack 6 to the storage position 201, the lifting assembly 42 can drive the access assembly 43 to rise, and the receiving portion 431 of the access assembly 43 protrudes out of the lifting groove 202, so as to shorten the transfer time of the test tube rack 6.

[0120] Specifically, step S2 includes the following steps:

[0121] S21, drive the first driving member 421 to drive the rotating member 422 to rotate.

[0122] S22, the rotating member 422 drives the lifting plate 424 to move upward, so as to drive the first transmission member 433 to move upward and protrude out of the lifting groove 202.

[0123] Among them, during the process of the transfer component 3 transferring the test tube rack 6 to the storage position 201, the first driving member 421 is synchronously driven to operate, so that the first driving member 421 drives the rotating member 422 to rotate. The eccentric convex column on the back of the rotating member 422 rotates eccentrically relative to the output shaft of the first driving member 421, and with the cooperation of the strip-shaped sliding groove 425 in the lifting plate 424, the rotational movement of the rotating member 422 is converted into the upward movement of the lifting plate 424 on the connecting seat 41, driving the first transmission member 433 above the lifting plate 424 to move upward, and protruding the receiving portion 431 of the first transmission member 433 out of the jacking groove 202, so that the first transmission member 433 can complete the feeding action of the test tube rack 6.

[0124] Specifically, step S3 includes the following steps:

[0125] S31, determine that the test tube rack 6 faces the storage position 201, drive the third driving member 332, and drive the second transmission member 331 to transmit inside the storage position 201, so that the test tube rack 6 moves towards the storage position 201.

[0126] S32, drive the second driving member 432, drive the first transmission member 433 to transmit inside the storage position 201, and feed the test tube rack 6 into the storage position 201.

[0127] Among them, after the transfer component 3 transfers the test tube rack 6 to the docked storage position 201 and rotates the storage position 201 to face the storage position 201, the third driving member 332 drives the second transmission member 331 to transmit, so that the second transmission member 331 drives the test tube rack 6 to move towards the storage position 201, so that the receiving portion 431 of the first transmission member 433 abuts against the bottom of the test tube rack 6. Under the drive of the second driving member 432, the first transmission member 433 operates, transfers the test tube rack 6 from the transfer component 3 to the storage position 201, and completes the feeding action of the test tube rack 6.

[0128] Through the cooperation of the third driving member 332 and the second driving member 432, the transfer power is provided for the test tube rack 6 to be transferred from the transfer component 3 to the storage position 201 to ensure the stable transfer of the test tube rack 6.

[0129] In addition, it should also be noted that in steps S5 to S7, when the test tube rack 6 needs to be transferred out of the storage position 201, the first driving member 421 also drives the rotating member 422 to rotate, and with the cooperation of the eccentric convex column on the back of the rotating member 422 and the strip-shaped sliding groove 425 in the lifting plate 424, the first transmission member 433 of the lifting plate 424 is jacked up, realizing jacking up the test tube rack 6 from the storage position 201. Subsequently, the second driving member 432 drives the first transmission member 433 to transmit outside the storage position 201, realizing transferring the test tube rack 6 to the transfer component 3 and completing the transfer-out action of the test tube rack 6.

[0130] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
