In one or more embodiments, the support base 325 is inserted into a limit slot on the fixed base plate 3211 to increase the securement of the installation. Based on the orientation shown in fig. 1, the support pedestal 325 is a box that is open at the top to allow the bottom-located standby sample consumable 326 (i.e., the standby sample consumable 326 closest to the support pedestal 325) to extend into the interior of the support pedestal 325 through the top opening to avoid interference. In addition, the bottom standby sample consumable 326 rests on the top circumferential edge of the support pedestal 325, and then the other standby sample consumables 326 are sequentially stacked on the bottom standby sample consumable 326.

With continued reference to FIG. 3, in one or more embodiments, each stack module 32 further includes a detection device 324. The detection device 324 is used to detect the height of the standby sample consumable 326 within the chamber 323. In one or more embodiments, a detecting device 324 corresponding to the height of each layer of standby sample consumable 326 is disposed on the first limiting post 3221 of the left limiting plate 322a, so as to detect whether the standby sample consumable 326 with the corresponding height is used. The number of test devices 324 in the stacking module 32 for placement of different types of standby sample consumables 326 varies. When the height of the spare sample consumables 326 is higher, the number of layers of the corresponding type of spare sample consumables 326 that can be stacked on the stacking module 32 is reduced, and the number of detection devices 324 in the stacking module 32 is correspondingly reduced. In addition, the detection device 324 is in communication with the controller of the sample processing device 1, so as to transmit the detection result to the controller, and further control the movement of the transfer module 33.

As shown in fig. 1, in one or more embodiments, the transport module 33 includes a three-dimensional platform 331 and a robot 332. The three-dimensional platform 331 is fixed to the support riser 12. The manipulator 332 is movably fixed to the three-dimensional platform 332 by a driving motor (not shown). In one or more embodiments, the three-dimensional platform 331 includes an X-directional slide rail 3311, a Y-directional slide rail 3312, and a Z-directional slide rail 3311. Based on the orientation shown in fig. 1, the X-direction slide rail 3311 is fixed to the top of the left and right support risers 121 and 122 of the base frame 10 and extends in the substantially right-left direction. The Y-direction slide rail 3312 extends generally in the front-to-rear direction, and the rear end of the Y-direction slide rail 3312 is slidably fixed to the X-direction slide rail 3311. The Z-slide rail 3313 extends substantially in the up-down direction, and a middle portion of the Z-slide rail 3313 is slidably fixed to the Y-slide rail 3312. The robot 332 is movably secured to the Z-slide rail 3313 of the three-dimensional platform 331. That is, the robot 332 may move up and down along the Z-direction slide rail 3313 by driving of the driving motor. Thus, with the above arrangement, the robot 332 can flexibly move in the left-right direction, the front-rear direction, and the up-down direction to grasp and transfer the standby sample consumable 326. In one or more embodiments, the manipulator 332 includes a mechanical jaw 3321 for grasping the sample consumable 23 and the standby sample consumable 326. The mechanical clamping jaw 3321 can be opened and closed under the drive of a motor so as to grasp and put down the consumable.

As shown in fig. 1, in one or more embodiments, the sample processing device 1 of the present invention further comprises a code scanner 40. The scanner 40 may scan the information code disposed on the standby sample consumable 326 to obtain the type of the standby sample consumable 326, facilitating the transfer module 33 to accurately identify the standby sample consumable 326 that matches the depleted sample consumable 23. In one or more embodiments, a scanner mounting plate 3322 is provided on the mechanical clamping jaw 3321 and a scanner 40 is mounted on the scanner mounting plate 3322 to conveniently and accurately scan the information code on the spare sample consumable 326.

When the sample processing device 1 of the present invention is in use, the sensing module 31 arranged on the sample processing module 22 will detect in real time whether the sample consumable 23 is spent. When the sensing module 31 detects that the sample consumable 23 is spent, the controller will drive the transport module 33 to move to the area where the stacking module 32 is located. The scanner 40 will scan and identify the information code on the spare sample consumable 326. When the controller receives the scan result, it will compare whether the spare sample consumable 326 matches the used sample consumable 23. If the result is negative, the transfer module 33 will continue to move to other stacking modules 32; if so, the transfer module 33 will be positioned at the stack module 32. Next, the detecting device 324 on the stacking module 32 will detect the standby sample consumable 326 stacked on the uppermost layer of the fixing base 321, so as to drive the manipulator 332 of the transferring module 33 to accurately grasp the standby sample consumable 326. After the standby sample consumable 326 is grasped, the manipulator 332 will transfer the standby sample consumable 326 to the corresponding sample processing module 20 under the control of the controller to replace the sample consumable 326.

Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments.
