[0064] Referring to Figures 1 to 8 As shown in the drawings, the present application provides a sample storage device, which comprises a device main body 1000, a storage warehouse 2000, a transfer mechanism 3000, and the like. The inside of the device main body 1000 has a storage chamber 1001, as shown in the drawings. Figure 4 and Figure 5 As shown in the drawings, in order to more clearly define the orientation of the sample storage device, the storage chamber 1001 is defined to have an X-axis direction, a Y-axis direction, and a Z-axis direction.

[0065] At this time, the storage warehouse 2000 is arranged in the storage chamber 1001 of the device main body 1000, and the storage warehouse 2000 contains a plurality of storage positions 2001. The plurality of storage positions 2001 are distributed in a plurality of columns along the Y-axis direction and a plurality of rows along the Z-axis direction. Each of the plurality of storage positions 2001 can be used to arrange a sample rack 100, so that the sample rack 100 can be arranged in any one of the plurality of storage positions 2001 according to requirements.

[0066] Among them, when the sample rack 100 is arranged and removed relative to the storage position 2001, the sample rack 100 enters and exits the storage position 2001 along the X-axis direction, that is, the outlet and inlet directions of the storage position 2001 at this time are along the X-axis direction. The sample rack 100 is used to arrange a plurality of sample tubes 200, and the plurality of sample tubes 200 can be arranged in the sample rack 100 in a specific manner, which is not limited here.

[0067] The transfer mechanism 3000 is arranged in the storage chamber 1001 of the device main body 1000, and the function of the transfer mechanism 3000 is to transfer a plurality of sample racks 100 in the storage chamber 1001 of the device main body 1000 relative to the storage bin body 2000, that is, to take out the corresponding sample rack 100 from the plurality of storage bin positions 2001 of the storage bin body 2000, and then transfer the corresponding sample rack 100 out of the sample storage device and deliver it to the auxiliary device of the other stage to perform other stage processing on the sample rack 100. In addition, the function of the transfer mechanism 3000 also includes cooperating with the auxiliary device of the other stage to receive the sample rack 100, transfer the sample rack 100 into the storage chamber 1001 of the device main body 1000, and according to the requirement, arrange the sample rack 100 on a certain storage bin position 2001 of the storage bin body 2000 to achieve the collection of the sample rack 100.

[0068] The transfer mechanism 3000 can adopt various transfer forms. For example, in one embodiment, as shown in Figure 4 and Figure 5 The transfer mechanism 3000 can include a displacement assembly 3100 and a grabbing assembly 3200, and the displacement assembly 3100 is in control connection with the grabbing assembly 3200. At this time, the displacement assembly 3100 can be used to control the grabbing assembly 3200 to move in the X-axis direction, the Y-axis direction and the Z-axis direction in the storage chamber 1001 of the device main body 1000, that is, the displacement assembly 3100 can control the grabbing assembly 3200 to move in the X-axis direction, or move in the Y-axis direction, or move in the Z-axis direction in the storage chamber 1001 of the device main body 1000. The movement in the X-axis direction, the Y-axis direction and the Z-axis direction can be performed synchronously or individually, which needs to be determined according to the movement requirement of the grabbing assembly 3200, and is not limited here. Based on the control of the displacement assembly 3100 on the grabbing assembly 3200, the grabbing assembly 3200 can move in the three-dimensional space in the storage chamber 1001 of the device main body 1000.

[0069] In one of the embodiments, the grabbing component 3200 is configured to move along the X-axis direction to control the moving position of the sample rack 100 relative to the storage positions 2001 of the storage body 2000 under the driving of the displacement component 3100. At this time, the displacement component 3100 of the present application controls the moving position of the grabbing component 3200 in the Y-axis direction and the Z-axis direction mainly for moving relative to the storage body 2000, thereby moving relative to the storage body 2000 to any one of the storage positions 2001 contained in the storage body 2000. While the displacement component 3100 controls the moving position of the grabbing component 3200 in the X-axis direction mainly for transferring the sample rack 100 relative to the storage positions 2001 of the storage body 2000, including moving the sample rack 100 out of the storage positions 2001 of the storage body 2000 and moving the sample rack 100 into the storage positions 2001 of the storage body 2000.

[0070] As can be seen from the above, when the displacement component 3100 controls the grabbing component 3200, the moving control along the X-axis direction can be used to control the grabbing component 3200 to move the sample rack 100 out of or into the storage positions 2001 of the storage body 2000 along the X-axis direction. Compared with the existing transfer mode of the sample rack 100, the transfer mode of the sample rack 100 of the present application is a horizontal pushing and pulling mode, i.e., pushing or pulling the sample rack 100 horizontally along the X-axis direction without lifting. This horizontal pushing and pulling mode only controls the sample rack 100 to move horizontally (in the X-axis direction) when moving the sample rack 100 out of or into the storage positions 2001, without any movement in the height direction.

[0071] Therefore, the transfer of the sample rack 100 does not occupy the space in the height direction (Z-axis direction), so that the height direction of the storage chamber 1001 of the device body 1000 does not have to increase the design height for the movement of the displacement component 3100, and the displacement component 3100 does not have to increase the design height for avoiding when moving the sample rack 100 out of or into the storage positions 2001, which can reduce the height design space of the sample storage device in the height direction, so that the storage chamber 1001 of the device body 1000 can accommodate more sample racks 100, increasing the accommodation ratio of the sample racks 100.

[0072] Continuing to refer to Figure 6 and Figure 7As shown, in one of the embodiments, the grabbing assembly 3200 comprises a grabbing element 3210 and a driving device 3220. Among them, the grabbing element 3210 is used to grab the sample rack 100, and the grabbing mode can include hooking, clamping, magnetic attraction connection, bonding, clamping and other grabbing modes, which are not limited as long as they can meet the grabbing requirements and facilitate the connection or separation of the sample rack 100. The driving device 3220 is connected with the grabbing element 3210, and the driving device 3220 can provide power to control the grabbing element 3210 to grab or move away from the sample rack 100, so that the grabbing element 3210 grabs the sample rack 100 when it approaches the sample rack 100, and the grabbing element 3210 releases the sample rack 100 after grabbing and moves away from the sample rack 100.

[0073] The driving device 3220 can be selected in multiple ways, for example, in one of the embodiments, the driving device 3220 is a rotary motor, which has a rotary driving function. At this time, the output shaft of the rotary motor is connected with the grabbing element 3210, and the rotary motor can be used to control the grabbing element 3210 to rotate along the axis of the output shaft of the rotary motor, so that the grabbing element 3210 approaches and grabs the sample rack 100 by rotating along the axis, and releases and moves away from the sample rack 100 by rotating along the axis. Among them, the axis of the output shaft of the rotary motor can be defined as perpendicular to the X-axis direction, so that the rotation of the grabbing element 3210 is along the X-axis direction as the axis.

[0074] In one of the embodiments, one end of the grabbing element 3210 is a connecting part 3211, and the other end of the grabbing element 3210 is a grabbing part 3212. The connecting part 3211 of the grabbing element 3210 is connected with the output shaft of the rotary motor, and the grabbing part 3212 of the grabbing element 3210 is used to grab the sample rack 100. Among them, the sample rack 100 can be provided with a grabbing hole 102, and the grabbing part 3212 of the grabbing element 3210 can be provided with a grabbing hook matched with the above-mentioned grabbing hole 102, so that Figure 6 when the grabbing element 3210 approaches the sample rack 100 by rotating along the axis, the grabbing hook of the grabbing element 3210 can hook the grabbing hole 102 on the sample rack 100, thereby realizing the grabbing of the sample rack 100. When the grabbing element 3210 rotates away from the sample rack 100 by rotating along the axis, the grabbing hook of the grabbing element 3210 can be separated from the grabbing hole 102 on the sample rack 100, thereby realizing the release of the sample rack 100.

[0075] Continuing to refer to Figures 4 to 6As shown, the displacement assembly 3100 can include a first guide rail 3101, a second guide rail 3102, and an assembly end platform 3103, the first guide rail 3101 and the second guide rail 3102 are linear rails, the guide track of the first guide rail 3101 is parallel to the Y-axis direction, and the guide track of the second guide rail 3102 is parallel to the Z-axis direction.

[0076] Therefore, the first guide rail 3101 is arranged in the storage chamber 1001 of the device main body 1000, the second guide rail 3102 is movably arranged along the guide track of the first guide rail 3101 and reciprocally linearly moves along the Y-axis direction, the assembly end platform 3103 is movably arranged along the guide track of the second guide rail 3102 and reciprocally linearly moves along the Z-axis direction, at this time, the grabbing assembly 3200 is arranged on the assembly end platform 3103, and the grabbing assembly 3200 moves synchronously with the assembly end platform 3103. Meanwhile, the assembly end platform 3103 can also be provided with a third guide rail 3104, the guide track of the third guide rail 3104 is parallel to the X-axis direction, and the grabbing assembly 3200 is movably arranged along the guide track of the third guide rail 3104 and reciprocally linearly moves along the X-axis direction.

[0077] Based on the movable arrangement of the first guide rail 3101 and the second guide rail 3102, the assembly end platform 3103 can drive the grabbing assembly 3200 to move in the Y-axis direction and the Z-axis direction, and adjust the relative position with respect to different storage positions 2001 of the storage bin body 2000. Meanwhile, through the third guide rail 3104, the grabbing assembly 3200 can move in the X-axis direction to push and pull the sample rack 100 of different storage positions 2001, so as to realize the removal and insertion of the sample rack 100. Among them, the assembly end platform 3103 can be used for temporarily storing the sample rack 100 during the transfer process of the sample rack 100, therefore, when the sample rack 100 is removed from the storage position 2001, it can be pulled transversely by the grabbing assembly 3200 to the assembly end platform 3103, and then transferred to a specific position and transferred out of the storage chamber 1001 of the device main body 1000. Meanwhile, when the sample rack 100 is inserted into the storage position 2001, the sample rack 100 can also be transferred to the assembly end platform 3103 from outside the storage chamber 1001 of the device main body 1000, and then pushed transversely by the grabbing assembly 3200 to the corresponding storage position 2001 of the storage bin body 2000.

[0078] Based on the above design scheme, the number of the storage bin body 2000 can also be set to two, such as Figure 5As shown, the transfer mechanism 3000 is arranged between the two storage chambers 2000. Meanwhile, the number of the grabbing elements 3210 is also set to two, and the output shaft of the rotating motor is connected with the two grabbing elements 3210. At this time, the output shaft of the rotating motor has a forward rotation direction and a reverse rotation direction, the rotating motor is used to drive one of the grabbing elements 3210 to rotate along the forward rotation direction, so as to grab the sample rack 100 on one of the storage chambers 2000, and the rotating motor is used to drive the other grabbing element 3210 to rotate along the reverse rotation direction, so as to grab the sample rack 100 on the other storage chamber 2000. The grabbing mode is the same as the above-mentioned mode, and will not be described here.

[0079] In addition, in one embodiment, the transfer mechanism 3000 can also include a pushing assembly 3300, and the displacement assembly 3100 is drivingly connected with the pushing assembly 3300 for controlling the pushing assembly 3300 to move along the Y-axis direction and the Z-axis direction in the storage chamber 1001 of the device body 1000. For example, the pushing assembly 3300 is also arranged on the assembly end platform 3103, and moves synchronously with the assembly end platform 3103. Therefore, based on the movable assembly of the first guide rail 3101 and the second guide rail 3102, the assembly end platform 3103 drives the pushing assembly 3300 to move along the Y-axis direction and the Z-axis direction, and adjusts the relative position with respect to different storage positions 2001 of the storage chamber 2000. When the pushing assembly 3300 is opposite to a certain storage position 2001, the pushing assembly 3300 can be used to apply a pushing force to the sample rack 100 along the Y-axis direction, so as to push the sample rack 100 out.

[0080] In one embodiment, the pushing assembly 3300 includes a pushing device 3310 for applying a pushing force to the sample rack 100 along the Y-axis direction. The pushing device 3310 can adopt any mechanism capable of providing a linear pushing force, for example, a linear cylinder, a linear telescopic rod, etc., which will not be limited here. In addition, the pushing assembly 3300 can also include a guide element 3320 for guiding contact with the sample rack 100, guiding the sample rack 100 to move along the Y-axis direction, preventing the sample rack 100 from deviating in position during the transfer process, and accurately moving into and out of different storage positions 2001 of the storage chamber 2000.

[0081] Continuing to refer to Figures 1 to 3As shown, in one embodiment, the device body 1000 has a box front side 1010, a box back side 1020, a box left side 1030 and a box right side 1040, which enclose the device body 1000 along the circumference of the device body 1000, the box left side 1030 and the box right side 1040 of the device body 1000 are oppositely arranged along the X-axis direction, and the box front side 1010 and the box back side 1020 of the device body 1000 are oppositely arranged along the Y-axis direction. Meanwhile, the device body 1000 can include an internal skeleton and a heat preservation material arranged on the internal skeleton.

[0082] Based on the above setting of the device body 1000, the box front side 1010 of the device body 1000 can be provided with an access door 1100, and the access door 1100 is provided with at least one of a perspective window 1101 and a control screen 1102.
