[0064] See also Figures 1 to 8 As shown, the present application provides a sample storage device, which includes a device body 1000, a storage chamber 2000, and a transfer mechanism 3000. The device body 1000 has a storage chamber 1001 inside. Figure 4 and Figure 5 As shown, 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 bin body 2000 is disposed in the storage chamber 1001 of the device body 1000, and the storage bin body 2000 includes a plurality of storage bins 2001, and the plurality of storage bins 2001 are distributed in a plurality of columns along the Y-axis direction and in a plurality of rows along the Z-axis direction. Each storage bin 2001 in the plurality of storage bins 2001 can be used to set the sample rack 100, so that the sample rack 100 can be set in any storage bin 2001 according to the requirements.

[0066] It is defined that when the sample rack 100 is set relative to and leaves the storage bin 2001, the sample rack 100 enters and exits the storage bin 2001 along the X-axis direction, that is, at this time, the exit and entrance directions of the storage bin 2001 are along the X-axis direction. The sample rack 100 is used to set a plurality of sample tubes 200, and the plurality of sample tubes 200 can be distributed and set in the sample rack 100 in a specific manner, which is not limited here.

[0067] The transfer mechanism 3000 is disposed in the storage chamber 1001 of the device body 1000. The function of the transfer mechanism 3000 is to transfer a plurality of sample racks 100 in the storage chamber 1001 of the device body 1000 relative to the storage bin 2000, that is, to take out the corresponding sample racks 100 from the plurality of storage bins 2001 of the storage bin 2000, leave the storage bin 2000, and transfer the corresponding sample racks 100 to the outside of the sample storage device, and deliver them to the auxiliary devices of other stages to perform other stage processing on the sample racks 100. In addition, the function of the transfer mechanism 3000 also includes cooperating with the auxiliary devices of other stages, receiving the sample racks 100, transferring the sample racks 100 to the storage chamber 1001 of the device body 1000, and placing the sample racks 100 in a certain storage bin 2001 of the storage bin 2000 according to the needs, so as to realize the collection of the sample racks 100.

[0068] The transport mechanism 3000 can adopt a variety of transport forms. For example, in one embodiment, Figure 4 and Figure 5 As shown, the transport mechanism 3000 may include a displacement component 3100 and a gripping component 3200, and the displacement component 3100 is connected to the gripping component 3200 by control. At this time, the displacement component 3100 can be used to control the gripping component 3200 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction in the storage chamber 1001 of the device body 1000, that is, the displacement component 3100 can control the gripping component 3200 to move along the X-axis direction, or along the Y-axis direction, or along the Z-axis direction in the storage chamber 1001 of the device body 1000. The movement of the position in the X-axis direction, the Y-axis direction, and the Z-axis direction can be performed synchronously or separately, which needs to be determined according to the movement requirements of the gripping component 3200, which is not limited here. Based on the control of the displacement component 3100 on the gripping component 3200, the gripping component 3200 can be moved in three-dimensional space in the storage chamber 1001 of the device body 1000.

[0069] In one embodiment, the grabbing assembly 3200 is used to control the moving position of the sample rack 100 relative to the storage bin 2001 of the storage bin body 2000 along the X-axis direction under the drive of the displacement assembly 3100. At this time, the displacement assembly 3100 of the present application controls the moving position of the grabbing assembly 3200 in the Y-axis direction and the Z-axis direction mainly for moving relative to the storage bin body 2000, thereby moving relative to the storage bin body 2000 to any one of the plurality of storage bins 2001 included in the storage bin body 2000. The displacement assembly 3100 controls the moving position of the grabbing assembly 3200 in the X-axis direction mainly for transporting the sample rack 100 relative to the storage bin 2001 of the storage bin body 2000, including moving the sample rack 100 out of the storage bin 2001 of the storage bin body 2000, and moving the sample rack 100 into the storage bin 2001 of the storage bin body 2000.

[0070] As can be seen from the above, when the displacement assembly 3100 controls the grabbing assembly 3200, the movement control along the X-axis direction can be used to control the grabbing assembly 3200 to move out of or into the sample rack 100 relative to the storage bin 2001 of the storage bin body 2000 along the X-axis direction. Compared with the existing transportation method of the sample rack 100, the transportation method of the sample rack 100 in the present application is a lateral push-pull method, that is, the sample rack 100 is pushed or pulled out laterally along the X-axis direction without lifting. This lateral push-pull movement method only controls the sample rack 100 to move in the lateral direction (X-axis direction) when moving out of or into the sample rack 100, and does not cause any movement in the height direction.

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

[0072] Continue reading Figure 6 and Figure 7As shown, in one embodiment, the grabbing assembly 3200 includes a grabbing element 3210 and a driving device 3220. The grabbing element 3210 is used to grab the sample rack 100. The grabbing method may include hooking, snapping, magnetic connection, bonding, clamping and other grabbing methods, which are not limited to this method, as long as the grabbing requirements can be met and the sample rack 100 can be conveniently connected or separated. The driving device 3220 is connected to the grabbing element 3210, and the driving device 3220 can provide power to control the grabbing element 3210 to grab the sample rack 100 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 grabbing of the sample rack 100 and moves away from the sample rack 100.

[0073] The driving device 3220 can be selected in a variety of ways. For example, in one embodiment, 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 to the grasping element 3210. The rotary motor can be used to control the grasping element 3210 to rotate along the axis of the output shaft of the rotary motor, so that the grasping element 3210 can approach and grasp the sample rack 100 through the fixed-axis rotation, and release and move away from the sample rack 100 through the fixed-axis rotation. Among them, the axis of the output shaft of the rotary motor can be defined as perpendicular to the X-axis direction, so the rotation of the grasping element 3210 is fixed-axis rotation with the X-axis direction as the axis.

[0074] In one embodiment, one end of the grasping element 3210 is a connecting portion 3211, and the other end of the grasping element 3210 is a grasping portion 3212. The connecting portion 3211 of the grasping element 3210 is connected to the output shaft of the rotating motor, and the grasping portion 3212 of the grasping element 3210 is used to grasp the sample rack 100. The sample rack 100 may be provided with a grasping hole 102, and the grasping portion 3212 of the grasping element 3210 may be provided as a grasping hook that cooperates with the grasping hole 102. Figure 6 As described above, when the gripping element 3210 approaches the sample rack 100 by rotating along a fixed axis, the gripping hook of the gripping element 3210 can hook the gripping hole 102 on the sample rack 100, thereby gripping the sample rack 100. When the gripping element 3210 moves away from the sample rack 100 by rotating along a fixed axis, the gripping hook of the gripping element 3210 can disengage from the gripping hole 102 on the sample rack 100, thereby releasing the sample rack 100.

[0075] Continue reading Figures 4 to 6As shown, the displacement component 3100 may include a first guide rail 3101, a second guide rail 3102 and a component end platform 3103. The first guide rail 3101 and the second guide rail 3102 are both 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 disposed in the storage chamber 1001 of the device body 1000, the second guide rail 3102 can be movably assembled on the first guide rail 3101 along the guide track of the first guide rail 3101, and reciprocate linearly along the Y-axis direction, the component end platform 3103 is movably assembled on the second guide rail 3102 along the guide track of the second guide rail 3102, and reciprocate linearly along the Z-axis direction, at this time, the grabbing component 3200 is disposed on the component end platform 3103, and the grabbing component 3200 moves synchronously with the component end platform 3103. At the same time, the component 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, the grabbing component 3200 is movably assembled on the third guide rail 3104 along the guide track of the third guide rail 3104, and reciprocates linearly along the X-axis direction.

[0077] Based on the movable assembly of the first guide rail 3101 and the second guide rail 3102, the component end platform 3103 can drive the grabbing component 3200 to move in the Y-axis direction and the Z-axis direction, and adjust the relative position relative to the different storage positions 2001 of the storage bin body 2000. At the same time, through the third guide rail 3104, the grabbing component 3200 can move in the X-axis direction to push and pull the sample racks 100 in different storage positions 2001, so as to achieve the removal and insertion of the sample racks 100. Among them, the component end platform 3103 can be used to temporarily store the sample racks 100 during the transportation process of the sample racks 100. Therefore, when the sample racks 100 are removed from the storage position 2001, they can be pulled horizontally by the grabbing component 3200 to the component end platform 3103, and then transported to a specific position to transfer to the outside of the storage chamber 1001 of the device body 1000. At the same time, when the sample rack 100 is moved from the storage position 2001 , the sample rack 100 can also be first transferred from the outside of the storage chamber 1001 of the device body 1000 to the component end platform 3103 , and then pushed horizontally to the corresponding storage position 2001 of the storage bin body 2000 by the grabbing component 3200 .

[0078] Based on the above design, the number of storage bins 2000 can also be set to two, such as Figure 5As shown, the transfer mechanism 3000 is arranged between two storage bins 2000. At the same time, the number of the grabbing elements 3210 is also set to two, and the output shaft of the rotary motor is connected to the two grabbing elements 3210. At this time, the output shaft of the rotary motor has a forward direction and a reverse direction. The rotary motor is used to drive one of the grabbing elements 3210 to rotate along the forward direction, thereby grabbing the sample rack 100 on one of the storage bins 2000, and the rotary motor is used to drive the other grabbing element 3210 to rotate along the reverse direction, thereby grabbing the sample rack 100 on the other storage bin 2000. The grabbing method is the same as the above-mentioned method, and will not be repeated here.

[0079] In addition, in one embodiment, the transport mechanism 3000 may further include a propulsion assembly 3300, and the displacement assembly 3100 is connected to the propulsion assembly 3300 for driving and controlling the propulsion 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 propulsion assembly 3300 is also arranged on the above-mentioned component end platform 3103, and moves synchronously with the component end platform 3103. Therefore, based on the movable assembly of the above-mentioned first guide rail 3101 and the second guide rail 3102, the component end platform 3103 drives the propulsion assembly 3300 to move in the Y-axis direction and the Z-axis direction, and adjusts the relative position relative to different storage positions 2001 of the storage bin body 2000. When the propulsion assembly 3300 is opposite to a certain storage position 2001, the propulsion assembly 3300 can be used to apply a driving force to the sample rack 100 along the Y-axis direction to push the sample rack 100 out.

[0080] In one embodiment, the propulsion assembly 3300 includes a propulsion device 3310, which is used to apply a propulsion force to the sample rack 100 along the Y-axis direction. The propulsion device 3310 can be any mechanism that can provide a linear propulsion force, for example, the propulsion device 3310 can be a linear cylinder, a linear telescopic rod, etc., which is not limited here. In addition, the propulsion assembly 3300 can also include a guide element 3320, which is used to contact with the sample rack 100 and guide the sample rack 100 to move along the Y-axis direction to prevent the sample rack 100 from deviating from its position during transportation, and accurately move it into different storage positions 2001 of the storage bin body 2000, and accurately move it out of different storage positions 2001 of the storage bin body 2000.
