DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1 As shown, a reagent card 500 storage device provided by the present invention includes: a fixing frame 100, a storage box 200 and a transport mechanism 300;

[0034] A channel 110 for moving the reagent card 500 is provided on the top plate of the fixing frame 100, the storage box 200 is located below the channel 110, the transfer mechanism 300 is provided between the storage box 200 and the channel 110, and the transfer mechanism 300 can move back and forth along the length direction of the storage box 200, and the transfer mechanism 300 is used to put the reagent card 500 code dropped from the channel 110 into the storage box 200.

[0035] Among them, a limiting structure is symmetrically provided along both sides of the channel 110. The limiting mechanism includes limiting grooves provided on both sides of the channel 110 and elastic protrusions installed in the limiting grooves. The protruding part of the elastic protrusion extends in the direction of the channel 110. When the reagent card 500 is compressed into the limiting groove by the reagent card 500 under the action of external force, the elastic protrusion returns to its original state after the reagent card 500 passes through, so as to block the passage of the next reagent card 500.

[0036] In this embodiment, the transport mechanism 300 is arranged between the storage box 200 and the channel 110, and the transport mechanism 300 can move back and forth along the length direction of the storage box 200, so that the reagent card 500 that falls from the channel 110 to the transport mechanism 300 is transported to a predetermined position by the transport mechanism 300, and the reagent card 500 is encoded in the storage box 200, so that the reagent card 500 can be neatly placed in the storage box 200, thereby increasing the number of reagent cards 500 stored in the storage box 200, and the reagent card 500 will not be exposed to the outside of the storage box 200; to solve the technical problem in the prior art that the reagent card 500 is pushed out in a fixed position, resulting in irregular reagent cards 500 falling into the storage box 200, resulting in a small number of reagent cards stored in the storage box 200.

[0037] like Figure 2 As shown, based on the above embodiment, the transfer mechanism 300 further includes a main frame 310, a support plate 320, a pressing plate 330 and a first driving module 340;

[0038] The main frame 310 is provided with a drop-out port 311, and the support plate 320, the pressure plate 330 and the first driving module 340 are all arranged on one side of the drop-out port 311, and both ends of the pressure plate 330 are fixed on the main frame 310. The support plate 320 and the first driving module 340 are arranged successively below the pressure plate 330, and the first driving module 340 can drive the support plate 320 to move toward the drop-out port 311 or away from one end of the drop-out port 311 to carry the reagent card 500 or make the reagent card 500 fall.

[0039] In this embodiment, when the reagent card 500 falls onto the transport mechanism 300, one end of the support plate 320 is located in the drop-off opening 311, which is used to carry the reagent card 500. When the main frame 310 moves to a predetermined position, the storage box 200 corresponds to the drop-off opening 311, and the first driving module 340 works to drive the support plate 320 to move toward the end away from the drop-off opening 311, so that the reagent card 500 falls into the storage box 200.

[0040] On the basis of the above embodiment, further, the transfer mechanism 300 further includes a clamping member 350;

[0041] The clamping member 350 is disposed at one end of the main frame 310 away from the support plate 320 and is capable of abutting against one side of the reagent card 500 and making the other side of the reagent card 500 abut against the pressing plate 330 .

[0042] The clamping member 350 may be a hydraulic cylinder or a telescopic rod.

[0043] In this embodiment, when the drop-clip opening 311 of the transport mechanism 300 reaches the set position, the clamping member 350 operates to clamp the reagent card 500 in the drop-clip opening 311. In this way, after the support plate 320 moves to the end away from the drop-clip opening 311, the reagent card 500 is still clamped in the drop-clip opening 311, which can prevent the reagent card 500 from folding into the storage box 200 after the support plate 320 is removed or during the process of being removed, thereby ensuring that the reagent card 500 can be neatly arranged in the storage box 200.

[0044] On the basis of the above embodiment, further, the clamping member 350 includes a pressing block 351 and an electromagnet 352;

[0045] The pressing block 351 is disposed at the middle of the main frame 310 at one end away from the supporting plate 320 , and the electromagnet 352 is disposed at one end of the pressing block 351 away from the latch hole 311 .

[0046] In this embodiment, the pressing block 351 is arranged in the middle of the end of the main frame 310 away from the support plate 320, so that when the pressing block 351 clamps the reagent card 500, the relative swing amplitude of the reagent card 500 is small. When the electromagnet 352 is energized, the pressing block 351 is pushed to clamp the reagent card 500. When the power is off, the pressing block 351 returns to its original position, and the reagent card 500 falls into the storage box 200.

[0047] On the basis of the above embodiment, further, the reagent card 500 receiving device further includes a second driving module 400 for driving the main frame 310;

[0048] The second driving module 400 includes a second driving motor 410 and a belt 420;

[0049] The second driving motor 410 is disposed on the bottom plate of the fixing frame 100 , one end of the belt 420 is connected to the output shaft of the second driving motor 410 , and the other end of the belt 420 is used to be connected to the main frame 310 .

[0050] A connection portion for connecting with the belt 420 may be provided on the main frame 310 so that the belt 420 can pass through and drive the main frame 310 to move.

[0051] In this embodiment, the second drive motor 410 is fixed on the bottom plate, and the belt 420 connects the output shaft of the second drive motor 410 and the main frame 310. The reciprocating motion of the main frame 310 is achieved by controlling the direction of the second drive motor 410.

[0052] On the basis of the above embodiment, further, the first driving module 340 includes a first driving motor, a gear arranged on the output shaft of the first driving motor, a rack arranged under the support plate 320 and a first optical coupler;

[0053] The gear cooperates with the rack, and the first optical coupler is used to control the rotation of the first driving motor so as to move the support plate 320 to a predetermined position.

[0054] In this embodiment, the first optical coupler can control the number of revolutions of the first drive motor, so that the moving distance of the support plate 320 can be controlled by the cooperation of the gear on the output shaft of the first drive motor and the rack on the support plate 320. When the reagent card 500 needs to be dropped, it is only necessary to make the end of the support plate 320 close to the card drop port 311 and the end of the pressure plate 330 close to the card drop port 311 in the same plane, thereby reducing the amount of movement of the support plate 320, making the internal structure of the overall device more compact, and reducing the workload of the first drive motor.

[0055] like Figure 3As shown, based on the above embodiment, further, slide rails 111 are provided on both sides of the bottom end of the top plate, and slide grooves 312 cooperating with the slide rails 111 are provided on the main frame 310 .

[0056] In this embodiment, the slide groove 312 on the main frame 310 is engaged with the slide rail 111 on the top plate, and the slide groove 312 can slide relative to the slide rail 111, and can also ensure the stability of the connection between the main frame 310 and the top plate.

[0057] like Figure 4 As shown, on the basis of the above embodiment, further, a plurality of baffles 210 are provided in the storage box 200, and the plurality of baffles 210 are evenly spaced along the length direction of the storage box 200, and the extension direction of the baffles 210 is perpendicular to the length direction of the storage box 200, so that the interior of the storage box 200 is divided into a plurality of accommodating chambers 220;

[0058] Furthermore, an extending direction of the channel 110 is perpendicular to a length direction of the storage box 200 .

[0059] A groove is disposed above each baffle plate 210 , and the centers of the grooves on the plurality of baffle plates 210 are on the same straight line.

[0060] In this embodiment, the interior of the storage box 200 is divided into multiple accommodating cavities 220 for accommodating the reagent card 500 by multiple spaced baffles 210. The size of each accommodating cavity 220 is slightly larger than the size of the reagent card 500 so that the reagent card 500 can stably fall into the accommodating cavity 220.

[0061] On the basis of the above embodiment, further, the reagent card 500 receiving device further includes a locking mechanism 800;

[0062] The locking mechanism 800 is disposed on the bottom plate of the fixing frame 100, and the locking mechanism 800 is used to connect with the storage box 200;

[0063] The storage box 200 can be pulled out from below the top plate of the fixing frame.

[0064] The locking mechanism 800 may be a ball lock.

[0065] In addition, a track is provided on the bottom plate of the fixing frame 100, and a groove body matching the track is provided on the storage box 200, so that the storage box 200 can slide relative to the fixing frame 100, so as to facilitate the storage box 200 to be pulled out.

[0066] In this embodiment, the provision of the locking mechanism 800 can ensure that the storage box 200 is stably placed under the fixing frame 100 during the process of storing the reagent card 500 .

[0067] On the basis of the above embodiment, further, the reagent card 500 receiving device further includes a corresponding optical coupler 700 and a calibration optical coupler 600;

[0068] The opposing optical coupler is symmetrically arranged on both sides of the storage box 200 , and the opposing optical coupler 700 is used to monitor whether the amount of the reagent card 500 in the accommodating cavity 220 is normal; the calibration optical coupler 600 is used to make the reagent card 500 on the transport mechanism 300 fall into the accommodating cavity 220 .

[0069] In this embodiment, the setting of the calibration optical coupler 600 can enable the reagent card 500 on the transfer mechanism 300 to fall accurately into the accommodating cavity 220, ensuring the smooth operation of the equipment; the opposing optical coupler 700 is arranged on one side of the groove of the baffle 210. When the reagent card 500 passes through the position of the groove, the opposing optical coupler 700 can sense it and transmit the information to the control system. Through the judgment of the control system or the opposing optical coupler 700, it can be known whether the storage box 200 is full or the loading is abnormal.

[0070] The specific collection process is as follows:

[0071] The reagent card 500 is pushed out vertically from the channel 110 under the action of external force and falls onto the support plate 320 of the transport module;

[0072] The transport module with the reagent card 500 is moved horizontally along the slide slot 312 under the action of the second driving module 400, and the optical coupler 600 is calibrated to align the drop-off opening 311 on the transport module with any storage cavity in the storage box 200;

[0073] When the electromagnet 352 is energized, the pressing block 351 is pushed out, and the reagent card 500 is pressed between the side of the pressing plate 330 and the pressing block 351;

[0074] The support plate 320 moves horizontally under the drive of the first driving module 340, and stops moving when the space opened by the card opening 311 is larger than the width of the reagent card 500;

[0075] The electromagnet 352 is powered off, and the reagent card 500 falls vertically only under the action of gravity, and the reagent card 500 falls steadily into the storage box 200 through the accommodating cavity 220;

[0076] The above steps are repeated until the accommodating cavities 220 of all storage boxes 200 are full. The optical coupler 700 determines that the storage box 200 is full. The operator pushes the storage box 200, and the bumper pops the storage box 200 out, thereby clearing the waste cards in the storage box 200.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
