[0051] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.
[0052] The utility model provides a reagent card push selection device, such as Figure 1 to Figure 7 As shown, it includes a conveying mechanism 1 and a reagent bin mechanism 2, the reagent bin mechanism 2 has a bin body 21 and a reagent card drive assembly 22, the reagent card drive assembly 22 is assembled on the bin body 21, a plurality of card slots 211 are sequentially arranged in the transverse direction on one side of the bin body 21, an upper support plate 4 and a lower support plate 5 are arranged below the bin body 21, the upper support plate 4 is located at a first height, the lower support plate 5 is located at a second height, the first height is above the second height, and the conveying mechanism 1 and the upper support plate 4 are both arranged on the lower support plate 5. A track 51 is provided on the lower support plate 5, and a channel 41 is provided on the upper support plate 4, the channel 41 allows the reagent card 3 to pass through, the reagent card 3 located at the first height can be dropped to the second height through the channel 41, and then the reagent card 3 falls on the lower support plate 5, and the reagent card 3 falling on the lower support plate 5 can be transported to the track 51 by the conveying mechanism 1.
[0053] Furthermore, there are multiple reagent card driving components 22, and each card slot 211 is configured with a reagent card driving component 22. Except for the card slot 211 facing the channel 41, the remaining card slots 211 are used to store reagent cards 3. The reagent card driving component 22 can drive the reagent card 3 in the corresponding card slot 211 to move upward or downward. The reagent card driving component 22 corresponding to the card slot 211 facing the channel 41 can transport the reagent card 3 moved to the top of the channel 41 from the first height to the second height, and then transport the reagent card 3 to the track 51 through the conveying mechanism 1. In a possible embodiment, a total of 5 card slots 211 are provided on the warehouse body 21, which are marked as card slot No. 1 211, card slot No. 211, card slot No. 3 211, card slot No. 4 211, and card slot No. 5 211 from left to right, among which, the bottom of card slot No. 3 211 faces the channel 41, and the remaining four card slots 211 are used to place reagent cards 3. Multiple reagent cards 3 can be stacked in each card slot 211 at a time. When the reagent card 3 needs to be transported, the reagent card 3 in a card slot 211 can be transported to the first height by the reagent card driving component 22 to facilitate the transportation of the reagent card 3.
[0054] like Figure 1 , Figure 5 , Figure 7 As shown, the conveying mechanism 1 is arranged on the lower support plate 5, and the conveying mechanism 1 is equipped with a hook 12. When the reagent card 3 needs to be transported, the hook 12 is first controlled to move to the bottom of the target card slot 211, and then the reagent card driving component 22 is used to move the lowest reagent card 3 in the target card slot 211 downward to the first height, that is, the upper support plate 4. At this time, the reagent card 3 just falls into the upper hook hole 1221 of the hook 12, and the hook 12 is driven to move horizontally to a position facing the channel 41. Then, the reagent card 3 at the first height is moved through the channel 41 to the second height, that is, the lower support plate 5, by the reagent card driving component 22 facing the channel 41. At this time, the reagent card 3 just falls into the lower hook hole 1231 of the hook 12, and then the hook 12 is driven to transport the reagent card 3 to the track 51.
[0055] It should be noted that the lower support plate 5 is preferably designed with two tracks 51, which are arranged on both sides of the channel 41 respectively. According to actual needs, the hook 12 can be controlled to move left or right to transport the reagent card 3 to the left channel 41 or the right channel 41 to meet actual needs.
[0056] like Figure 1 to Figure 5As shown, the reagent card driving assembly 22 includes a reagent card tray 221, a first power body 222 and a tray connector 223. The first power body 222 is arranged on the back of the chamber body 21. The bottom of the tray connector 223 is connected to the reagent card tray 221. The first power body 222 is connected to the top of the tray connector 223. The first power body 222 is preferably an electric push rod, which can be extended or retracted to drive the tray connector 223 to drive the reagent card tray 221 to move upward or downward in the card slot 211, thereby driving the stacked reagent cards 3 located in the card slot 211 to move upward or downward.
[0057] Furthermore, a first groove 42 is provided on the upper support plate 4 , and the reagent card support plate 221 is adapted to the first groove 42 . When the reagent card support plate 221 moves and completely enters the first groove 42 , the top of the reagent card support plate 221 is flush with the top of the upper support plate 4 .
[0058] like Figure 6 As shown, the hook 12 has a front body 121 and two upper legs 122 and two lower legs 123 extending from the rear end of the front body 121. The space between the two upper legs 122 forms an upper hook hole 1221, and the space between the two lower legs 123 forms a lower hook hole 1231. The upper hook hole 1221 and the lower hook hole 1231 are arranged opposite to each other in the up-down direction. The upper support plate 4 is located between the upper legs 122 and the lower legs 123. The reagent card 3 is in the upper hook hole 1221 between the two upper legs 122 or in the lower hook hole 1231 between the two lower legs 123, so that the hook 12 can drive the reagent card 3 to move when it moves in the left-right direction. It can be seen that the upper space and the lower space of the upper pallet 4 in the utility model form two transportation spaces, the two upper legs 122 can push the reagent card 3 in the left and right directions in the upper space of the upper pallet 4, and the two lower legs 123 can push the reagent card 3 in the left and right directions in the lower space of the upper pallet 4.
[0059] like Figure 5 As shown, the conveying mechanism 1 also includes a second power body 11, a transmission body 13 and a guide rail 14. The guide rail 14 supports and guides the movement of the hook 12. The transmission body 13 is connected to the front end body 121. The second power body 11 can drive the transmission body 13 to drive the hook 12 to slide along the guide rail 14, and then drive the reagent card 3 to move in the left and right directions, and transport the reagent card 3 to the top of the channel 41. Among them, the transmission body 13 preferably adopts a chain or a belt, such as a V-belt, and the second power body 11 preferably adopts a motor. When the motor rotates, it drives the V-belt to move. The motor rotates forward or reversely to drive the V-belt to reciprocate to achieve the driving of the hook 12.
[0060] Specifically, a second groove is provided on the lower support plate 5, and the second groove is opposite to the channel 41. The reagent card support plate 221 is adapted to the second groove. When the reagent card support plate 221 enters the second groove, the top of the reagent card support plate 221 and the top of the lower support plate 5 are on the same plane. The reagent card support plate 221 facing the channel 41 can hold the reagent card 3 transported by the hook 12 and lower it into the second groove. At this time, the top of the reagent card support plate 221 is flush with the top of the lower support plate 5. The hook 12 can be driven to move left or right to transport the reagent card 3 to the top of the track 51, and the reagent card 3 falls into the track 51 under the action of gravity.
[0061] It should be noted that when the hook 12 transports the reagent card 3, only the reagent card support plate 221 holding the reagent card 3 is located between the upper leg 122 and the lower leg 123, and the corresponding reagent card support plates 221 in the other card slots 211 are all located above the upper leg 122. Therefore, when the hook 12 moves in the left and right directions, it will not interfere with the corresponding reagent card support plates 221 in other card slots 211.
[0062] The utility model adopts the Huarongdao principle and uses the card slot 211 as the intermediate transfer position to first control the hook 12 to move to the corresponding card slot 211 area. When the reagent card supporting plate 221 moves downward to completely enter the first groove 42, the reagent card 3 on the reagent card supporting plate 221 can be brought to the intermediate transfer position by the hook 12, and then the No. 3 reagent card supporting plate 221 is controlled to move downward to bring the reagent card 3 into the lower channel, and then the hook 12 is controlled to move left or right, and the reagent card 3 can be transported to the track 51, completing the transportation of the reagent card 3.
[0063] The working principle of the utility model is as follows:
[0064] Reagent card 3 is placed in the drawer slot 211, and the reagent card supporting plate 221 holds the reagent card 3. Each reagent card drawer slot 211 has a reagent card supporting plate 221, and the reagent card supporting plate 221 is connected with the electric push rod by the supporting plate connector 223. When the electric push rod is extended up and down, the reagent card supporting plate 221 can be driven to drive the reagent card 3 to move up and down. When in use, the reagent card 3 in which drawer slot 211 is selected by the program to stay in the upper or lower position. The reagent card 3 of which drawer slot 211 needs to be selected as long as the corresponding reagent card supporting plate 221 is selected to stay in the lower position, and the reagent card supporting plates 221 in the remaining drawer slots 211 stay in the upper position, waiting for the next step action.
[0065] The transport mechanism 1 has the function of moving the selected reagent card 3 onto the track 51 in a directional manner. Specifically, the transport mechanism 1 is driven by a hook motor to drive the hook 12 to select the reagent card 3 .
[0066] First, reagent card tray No. 1 221, reagent card tray No. 221, reagent card tray No. 4 221, and reagent card tray No. 5 221 are moved to the upper position to facilitate the movement of the hook 12 in the space below the tray. When the reagent card 3 in a certain card slot 211 needs to be selected, the hook 12 is moved to the corresponding reagent card tray 221 position. The reagent card tray 221 moves downward just enough to allow the reagent card 3 to enter the hook 12. The hook 12 then drives the reagent card 3 to move inward into the position of reagent card tray No. 3 221. Since the other reagent card trays 221 are in the upper position and will not affect the movement of the reagent card 3 inward, the reagent card tray 221 drags the reagent card 3 and moves it to the lower space.
[0067] The reagent card support plate 221 moves downward to the lower layer, that is, the position above the lower support plate 5, and then the hook 12 drives the reagent card 3 to move directly above the track 51. At this time, due to the gravity of the reagent card 3, it can automatically fall into the track 51, thereby completing the operation of freely moving the reagent card 3 in any card slot 211 to the track 51.
[0068] In addition, the reagent card tray 221 can also serve as an emergency position channel in addition to being selected as the intermediate transfer channel. The driving hook 12 stays in the middle position, and when the emergency reagent card 3 is directly placed on the No. 3 reagent card tray 221, the reagent card tray 221 descends to the lower layer, and then the reagent card 3 is transferred to the track 51 by the hook 12, and then the reagent card 3 is transferred out by other mechanisms.
