For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figure 1-Figure 7 As shown, the present embodiment provides a reagent storage module for storing reagents. The reagent storage module includes an anti-lifting device 2 and a storage seat 4. The storage seat 4 can be placed with a reagent storage consumable rack 3, and the reagent storage consumable rack 3 is used to store reagents. The anti-lifting device 2 can clamp the reagent storage consumable rack 3 so that the reagent storage consumable rack 3 is pressed against the storage seat 4. The reagent storage consumable rack 3 is generally encapsulated with a sealing film to prevent the reagent from evaporating or leaking, and also to prevent cross contamination. During the detection, it is necessary to use a pipette to puncture the sealing film and then absorb the reagent. After absorbing the reagent, when the pipette withdraws from the sealing film, the anti-lifting device 2 clamps the reagent storage consumable rack 3, which can prevent the reagent storage consumable rack 3 from being lifted by the pipette, prevent damage to the reagent storage consumable rack 3, and ensure the normal transfer of reagents, thereby improving the efficiency and accuracy of sample detection.

[0041] The anti-lifting device 2 includes a fixed component 21, a clamping component 22, a lifting component 23 and a linkage component 24. The fixed component 21 is fixedly arranged relative to the storage seat 4 in the reagent storage module. The lifting component 23 includes a lifting seat 231. The lifting seat 231 can be lifted relative to the fixed component 21. The linkage component 24 includes an abutment 241, a linkage 242 and an elastic member 243. The abutment 241 abuts on the lifting seat 231. The abutment 241 is connected to the lifting seat 231 through the elastic member 243. One end of the linkage 242 is rotatably connected to the abutment 241. The clamping component 22 includes a clamping claw 221, which moves along a first direction (such as Figure 2 and 3The left and right directions shown in the figure), the two opposite sides of the reagent storage consumables rack 3 are symmetrically provided with clamps 221, and the clamps 221 are arranged one by one with the linkage assembly 24, and the other end of the linkage member 242 is coaxially fixedly connected with the clamps 221, and each clamp 221 can be rotatably arranged on the storage seat 4 on a fixed axis, so as to be able to clamp the reagent storage consumables rack 3, so that the reagent storage consumables rack 3 is pressed against the storage seat 4. The lifting seat 231 rises, and because the abutment member 241 abuts against the lifting seat 231, the lifting seat 231 drives the abutment member 241 to move upward, and the abutment member 241 causes the linkage member 242 to rotate around the fixed axis (the rotating shaft 222 in the following text), thereby driving the clamps 221 to rotate. Since the clamps 221 are symmetrically arranged on the opposite sides of the reagent storage consumables rack 3, the rotation directions of the two clamps 221 are opposite, and the two clamps 221 are in an open state (such as Figure 2 As shown), in order to take and place the reagent storage consumables rack 3, during the fixed axis rotation of the linking member 242, the abutting member 241 will be driven to roll rightward along the first direction on the lifting seat 231 (as shown in FIG. Figure 2 As shown in the right side of the figure, the abutment member 241 will drive the elastic member 243 to extend; the lifting seat 231 descends, and the elastic deformation of the elastic member 243 will force the abutment member 241 to follow the lifting seat 231 to descend, and the abutment member 241 rolls leftward along the first direction on the lifting seat 231 (as shown in the right side of the figure). Figure 3 The left side shown in the figure) causes the linkage 242 to rotate in the opposite direction around the fixed axis (hereinafter referred to as the rotating axis 222), and the linkage 242 drives the clamping jaws 221 to rotate in the opposite direction around the fixed axis (hereinafter referred to as the rotating axis 222), so that the two clamping jaws 221 are in a clamping state, that is, the two clamping jaws 221 clamp the reagent storage consumables rack 3 (such as Figure 3 As shown), the reagent storage rack 3 can be prevented from being lifted up by the pipette, thereby preventing damage to the reagent storage rack 3, ensuring normal reagent pipetting, and thereby improving the efficiency and accuracy of sample testing.

[0042] like Figure 1 As shown, the reagent storage module also includes a bracket 1, and the storage seat 4 is fixedly mounted on the bracket 1.

[0043] Furthermore, the reagent storage consumable rack 3 includes a consumable plate 31 and a consumable flange 32, the consumable flange 32 is protruded from the consumable plate 31, the reagent is stored on the consumable plate 31, and the clamp 221 is clamped on the consumable flange 32 to prevent the reagent storage consumable rack 3 from being lifted by the pipette.

[0044] Furthermore, the reagent storage module also includes a temperature control module, which is arranged between the storage seat 4 and the reagent storage consumables rack 3 and is used to control the storage temperature of the reagent to ensure that the reagent is stored intact.

[0045] When the reagent needs to be stored at low temperature, the temperature control module can be a low-temperature control module; when the reagent needs to be stored at room temperature, the temperature control module may not work; when the reagent needs to be heated for storage, the temperature control module can be a heating module to complete the incubation of the reagent so that subsequent sample testing can proceed smoothly.

[0046] Of course, the low temperature control module, the normal temperature control module and the heating control module may exist at the same time, or may exist separately, or any two of the above modules may be freely combined. This embodiment does not limit this and can be set according to actual needs.

[0047] When there are at least two of the low temperature control module, the normal temperature control module and the heating control module, each of the above modules is respectively set in one-to-one correspondence with the storage seat 4, and is also set in one-to-one correspondence with the bracket 1. Each of the above modules corresponds to at least one reagent storage consumable rack 3, and each reagent storage consumable rack 3 corresponds to at least one group of clamping claw modules, and each group of clamping claw modules includes two clamping claws 221 arranged oppositely along the first direction, so that each reagent storage consumable rack 3 can be clamped to play a role in preventing it from being pulled up. As for whether each group of clamping claw modules is driven by the same lifting seat 231, it can be set according to actual conditions.

[0048] In this embodiment, the low temperature control module, the normal temperature control module and the heating control module exist at the same time, each of the above modules corresponds to a reagent storage consumable rack 3, each reagent storage consumable rack 3 corresponds to two groups of clamping claw modules, and the two groups of clamping claw modules are arranged at intervals along the second direction to clamp the four corners of the reagent storage consumable rack 3, thereby increasing stability. That is to say, in this embodiment, the number of the clamping claw modules is six groups, and each group of the clamping claw modules includes two clamping claws 221 arranged opposite to each other along the first direction.

[0049] Specifically, the second direction is arranged perpendicular to the first direction. Along the second direction, two clamping jaws 221 arranged opposite to each other in the two groups of clamping jaw modules are coaxially connected.

[0050] In this embodiment, the six groups of gripper modules are driven by two lifting seats 231, and the six groups of gripper modules can simultaneously open or clamp the corresponding reagent storage consumable racks 3. Of course, the number of lifting seats 231 is not limited to the above two, and can be set after comprehensive consideration of the number and distribution positions of the actual gripper modules.

[0051] like Figure 2 and Figure 3 As shown, since reagent storage consumable racks 3 of different specifications may be placed on the low temperature control module, the normal temperature control module and the heating control module, the shape and size of each clamp 221 in the six groups of clamp modules may be different. This embodiment does not limit this and can be set according to actual conditions.

[0052] like Figure 4As shown, the setting of the elastic member 243 can enable the abutment member 241 to adapt to the fixed-axis rotation of the connecting member 242, so that the abutment member 241 and the connecting member 242 will not interfere with each other in movement, and the elastic deformation of the elastic member 243 will also drive the abutment member 241 to reset when the lifting seat 231 descends, so as to realize the clamping of the reagent storage consumables rack 3 by the clamping claw 221.

[0053] Furthermore, the clamping assembly 22 also includes a rotating shaft 222, which can be rotatably arranged on the storage seat 4. The clamping jaw 221 and the connecting member 242 are both installed on the rotating shaft 222. The other end of the connecting member 242 rotates to drive the rotating shaft 222 to rotate, and then the rotating shaft 222 drives the clamping jaw 221 to rotate.

[0054] In this embodiment, the number of the rotating shafts 222 is six, and each rotating shaft 222 is mounted with two clamping jaws 221 that are oppositely arranged along the second direction and a linking member 242 .

[0055] like Figure 1 and Figure 5 As shown, the clamping jaw 221 includes an integrally formed rotating portion 2211, a clamping portion 2212 and a connecting portion 2213, the rotating portion 2211 is connected to the clamping portion 2212 through the connecting portion 2213, and the rotating portion 2211 can be rotatably arranged on the storage seat 4, specifically, the rotating portion 2211 is fixedly connected to the rotating shaft 222, and rotates around the central axis of the rotating shaft 222. The clamping portion 2212 and the connecting portion 2213 form a clamping area, and the consumable flange 32 of the reagent storage consumable rack 3 is clamped in the clamping area. The shape of the clamping jaw 221 is more convenient for clamping the consumable flange 32.

[0056] like Figure 1 , Figure 6 and Figure 7 As shown, the anti-lifting device 2 further includes a guide assembly 25 , and the driving seat 233 is guided by the guide assembly 25 .

[0057] Furthermore, the guide assembly 25 includes a guide block 251 and a guide rail 252 . The guide rail 252 is fixedly mounted on the fixed assembly 21 . The guide rail 252 extends in the vertical direction. The guide block 251 is mounted on the driving seat 233 . The guide block 251 is slidably disposed on the guide rail 252 .

[0058] Specifically, the guide assembly 25 and the lifting seat 231 are arranged in a one-to-one correspondence.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the lifting assembly 23 further includes a driving seat 233 , the lifting seat 231 is fixedly mounted on the driving seat 233 , and the driving seat 233 can be lifted and lowered relative to the fixed assembly 21 .

[0060] Furthermore, the lifting assembly 23 also includes a driving source 232, which can drive the driving seat 233 to rise and fall. Specifically, each lifting seat 231 is installed on the same driving seat 233. In other words, each lifting seat 231 is driven by the same driving source 232, and each lifting seat 231 rises and falls synchronously.

[0061] In this embodiment, each lifting seat 231 is driven by the same driving source 232. Of course, a driving source 232 may be provided separately for each lifting seat 231. Therefore, there is no limitation to this, and it can be set according to actual conditions.

[0062] Furthermore, the driving source 232 may be a through-type stepping motor, including an output shaft 2321 and a motor body 2322. The output shaft 2321 is fixedly mounted on the fixing assembly 21, and the output shaft 2321 can be raised and lowered relative to the motor body 2322. The motor body 2322 is connected to the driving seat 233. The output shaft 2321 is stationary, and the motor body 2322 is raised and lowered, driving the driving seat 233 to be raised and lowered, thereby driving each lifting seat 231 to be raised and lowered.

[0063] Further, the anti-lifting device 2 also includes a detection component 26, the detection component 26 includes a detection sensor 261 and a baffle 262, the baffle 262 is installed on the drive seat 233, the detection sensor 261 is installed on the fixed component 21, and the detection sensor 261 can detect whether the baffle 262 is in place. When the baffle 262 is in place, the force of the clamping jaws 221 clamping the reagent storage consumables rack 3 is appropriate. The setting of the detection component 26 can prevent the clamping jaws 221 from clamping the reagent storage consumables rack 3 due to excessive force, thereby extending the service life of the reagent storage consumables rack 3.

[0064] In this embodiment, since the lifting seats 231 are lifted synchronously, a set of detection components 26 is arranged near one of the lifting seats 231 to ensure that the clamping force of each clamping claw 221 is appropriate. Of course, the detection components 26 can also be arranged near both lifting seats 231, which is not limited in this embodiment.

[0065] Furthermore, the lifting seat 231 includes an abutting portion 2311 and a mounting portion 2312, the abutting portion 2311 and the mounting portion 2312 are arranged vertically, the abutting member 241 abuts against the abutting portion 2311, the mounting portion 2312 is mounted on the driving seat 233, and the dimension of the abutting portion 2311 along the first direction is greater than the dimension of the mounting portion 2312 along the first direction. Such an arrangement can reduce the volume of the driving seat 233 while ensuring that each abutting member 241 can abut against the abutting portion 2311 and that each abutting member 241 has space to roll along the first direction.

[0066] Further, the fixing assembly 21 includes a fixing base 211 and a fixing stand 212, the fixing base 211 and the fixing stand 212 are fixedly connected to form an L-shape, the fixing base 211 and the fixing stand 212 are both fixedly arranged relative to the bracket 1, one end of the output shaft 2321 of the driving source 232 is fixed to the fixing base 211, and the other end is fixedly connected to the fixing stand 212. The L-shaped fixing base 211 and the fixing stand 212 facilitate the installation of the driving source 232, the driving seat 233, the lifting seat 231 and the guide assembly 25, so as to guide the driving seat 233 and the lifting seat 231.

[0067] Furthermore, the lifting assembly 23 also includes a mounting seat 234 , and the other end of the output shaft 2321 is fixed on the mounting seat 234 , and the mounting seat 234 is fixedly mounted on the fixed stand 212 .

[0068] Specifically, the guide rail 252 and the detection sensor 261 are both fixedly mounted on the fixed stand 212 .

[0069] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
