Description

Technical Field

[0001] This utility model relates to the field of reagent kit storage technology, and in particular to a reagent kit storage mechanism. Background Technology

[0002] In in vitro diagnostics, life science experiments, and various rapid testing scenarios, reagent kits are typically packaged in individual small boxes. Each kit contains various reagents or sample processing tools required for specific tests or experiments, as well as instructions. Generally, room-temperature kits are stacked in their packaging boxes for storage, while kits requiring refrigeration are stored in refrigerators. During use, operators manually remove the corresponding kit, the patient submits the sample to the manual testing window, and the laboratory technician performs the test to achieve sampling and detection.

[0003] Currently, reagent kits are mainly stored in packaging boxes and refrigerators, and are retrieved manually, which affects work efficiency. In rapid testing scenarios, although vending machines can use push mechanisms to automatically dispense reagent kits to improve dispensing efficiency, in actual use, it is impossible to verify the quantity of reagent kits at the time of dispensing, and the timeliness of replenishment reminders is lacking. This can easily lead to empty pushes, where the push mechanism performs the push action when there are no reagent kits at the corresponding shelf position, resulting in untimely supply of reagent kits.

[0025] A bracket is vertically mounted on the first mounting base and located on one side of the push rod. The barcode scanner and the reflective sensor are parallel to each other and spaced apart on the bracket along the Z-axis.

[0026] When the reflective sensor is opposite to the detection port, the barcode scanner is opposite to the operation port.

[0027] In one embodiment, the pusher structure further includes:

[0028] A position detection unit is provided on the first mounting base and the second mounting base, and is used to detect the position of the push rod in the Y-axis direction and the X-axis direction.

[0029] In one embodiment, the position detection unit includes:

The operation port is located below the detection port and opposite to the outlet. The pusher structure is movably located on one side of the storage rack and can penetrate through the operation port and extend into the receiving cavity to push the reagent kit out of the outlet.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0056] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0058] In in vitro diagnostics, life science experiments, and various rapid testing scenarios, reagent kits are typically packaged in individual small boxes. Each kit contains various reagents or sample processing tools required for specific tests or experiments, as well as instructions. Generally, room-temperature kits are stacked in their packaging boxes for storage, while kits requiring refrigeration are stored in refrigerators. During use, operators manually remove the corresponding kit, the patient submits the sample to the manual testing window, and the laboratory technician performs the test to achieve sampling and detection.

[0059] Currently, reagent kits are mainly stored in packaging boxes and refrigerators, and are retrieved manually, which affects work efficiency. In rapid testing scenarios, although vending machines can use push mechanisms to automatically dispense reagent kits to improve dispensing efficiency, in actual use, it is impossible to verify the quantity of reagent kits at the time of dispensing, and the timeliness of replenishment reminders is lacking. This can easily lead to empty pushes, where the push mechanism performs the push action when there are no reagent kits at the corresponding shelf position, resulting in untimely supply of reagent kits.

[0060] This invention proposes a reagent kit storage mechanism to improve the automation of shipping while enhancing shipping reliability and accuracy.

[0061] Please see Figures 1 to 4In one embodiment, the storage mechanism of the reagent kit 00 includes a storage rack 100 and a pusher structure 200. The storage rack 100 has a receiving cavity inside and has a first side and a second side 110 located on opposite sides of the receiving cavity. The bottom of the first side has an outlet 130 communicating with the receiving cavity. The second side 110 has an operation port 112 and a detection port 111 communicating with the receiving cavity. The operation port 112 is located below the detection port 111 and opposite to the outlet 130. The pusher structure 200 is movably disposed on one side of the storage rack 100. The pusher structure 200 can pass through the operation port 112 and extend into the receiving cavity to push the reagent kit 00 out of the outlet 130.

[0062] The storage rack 100 provides storage space for the reagent kits 00. The reagent kits 00 are stacked in the storage rack along the Z-axis direction, i.e., the reagent kits 00 are placed in multiple rows and columns in the storage rack. The first side and the second side 110 are located on opposite sides of the reagent kits 00. The height of the outlet 130 is adapted to the height of a single reagent kit 00. The outlet 130 and the operation port 112 are opposite to the reagent kits 00 located in the bottom row. The detection port 111 is opposite to one of the rows of reagent kits 00 located directly above the bottom row of reagent kits 00. The reflective sensor 310 can be used to detect whether there are reagent kits 00 in the bottom row and whether restocking is needed. The position in the storage rack opposite to the detection port 111 is the detection position. There are multiple detection positions. When placing the reagent kits 00 in the storage rack, each column of reagent kits 00 will be stacked corresponding to one detection position. Further, in one embodiment, the storage rack 100 is located inside the device. The second side 110 of the storage rack 100 is provided with a linear guide rail 160 for sliding connection with the device. One end of the second side 110 is provided with a pull handle to facilitate the removal of the storage rack 100 from the equipment for replenishment, maintenance, and other operations. The storage rack 100 is also equipped with a micro switch 180, a magnet, and a fixing base 170. The magnet and the micro switch 180 are both located on the fixing base 170. The equipment is equipped with a trigger and a magnetic attraction component. When the storage rack 100 moves to the preset position of the equipment via the linear guide rail 160, the trigger activates the micro switch 180 to achieve positioning detection. At the same time, the magnetic attraction component attracts the magnet to fix the storage rack 100. The second side 110 of the storage rack 100 is provided with multiple first through holes 113 to reduce the overall weight. The equipment can be automated pharmacy equipment, reagent management equipment, integrated testing equipment, etc., and there are no restrictions here.

[0063] The pusher structure 200 is used to push out the reagent kits 00 on the storage rack 100 to achieve automatic dispensing. The pusher structure 200 is located on the side of the second side 110 facing away from the first side. The pusher structure 200 can move in the X-axis and Y-axis directions perpendicular to the Z-axis to face and pass through the operation port 112, thereby pushing out the bottom row of reagent kits 00 one by one from the outlet 130. After the bottom row of reagent kits 00 is pushed out, the upper row of reagent kits 00 fall to the bottom row to facilitate subsequent push out by the pusher structure 200.

[0064] When the detection port 111 detects that a reagent kit 00 is placed at the detection position, since the reagent kits 00 are stacked, it means that a reagent kit 00 is also placed at the bottom position. The pusher structure 200 can push out the bottom row of reagent kits 00. After the bottom row of reagent kits 00 is pushed out, the detection port 111 checks again whether there is a reagent kit 00 at the detection position, that is, whether a reagent kit 00 has fallen at the detection position. When no reagent kit 00 has fallen at the detection position, the remaining quantity of reagent kits 00 in that column can be known and compared with the recorded quantity of reagent kits 00 in that column to realize the quantity verification.

[0065] When no reagent kit 00 is detected at a detection position through detection port 111, it indicates that there are no reagent kits 00 at any position above the detection position. In one embodiment, when no reagent kit 00 is detected at any detection position through detection port 111, staff need to replenish the kit promptly to avoid subsequent empty pushes by the pusher structure 200. In another embodiment, when only one detection position is found to be without a reagent kit 00 through detection port 111, no replenishment is required. Instead, when multiple detection positions within the receiving cavity are all without reagent kits 00, i.e., when the detection positions corresponding to multiple rows of reagent kits 00 in the Z-axis direction are all without reagent kits 00, a replenishment warning is triggered, notifying the operator to replenish the kit. The number of warnings can be flexibly set according to actual needs and is not limited here.

[0066] The technical solution of this utility model involves setting a storage rack 100 and a pusher structure 200 in the storage mechanism of the reagent kit 00. The storage rack 100 has an internal cavity and has a first side and a second side 110 located on opposite sides of the cavity. The bottom of the first side has an outlet 130 communicating with the cavity. The second side 110 has an operation port 112 and a detection port 111 communicating with the cavity. The operation port 112 is located below the detection port 111 and opposite to the outlet 130. The pusher structure 200 is movably disposed on one side of the storage rack 100. The pusher structure 200 can pass through the operation port 112 and extend into the cavity to push the reagent kit 00 out of the outlet 130. Compared to existing storage mechanisms that only have a push structure, the technical solution of this utility model embodiment includes a detection port 111, located above the operation port 112. This allows a reflective sensor 310 to detect the presence of reagent kits 00 at the corresponding position before the pusher structure 200 performs its pushing action. This facilitates timely replenishment and avoids empty pushing. After the pusher structure 200 pushes out the bottom row of reagent kits 00, the detection port 111 determines whether any reagent kits 00 have fallen. If no reagent kits 00 have fallen, the quantity can be verified, improving the reliability and accuracy of the shipment. Simultaneously, the pusher structure 200 is movably mounted on one side of the storage rack 100, extending through the operation port 112 into the receiving cavity to push the reagent kits 00 out of the outlet 130, achieving automated shipment of the reagent kits 00 and improving shipment efficiency.

[0067] Please see Figure 5 In one embodiment, the receiving cavity includes a plurality of placement slots extending along the Z-axis direction, the plurality of placement slots being arranged in parallel along the X-axis direction, and a plurality of detection ports 111 and operation ports 112 being provided correspondingly, each placement slot being connected to a detection port 111 and an operation port 112.

[0068] Specifically, the receiving cavity is divided into multiple placement slots by multiple vertical plates 141 spaced apart. Reagent kits 00 are stacked in each placement slot along the Z-axis. The width of the placement slot is slightly larger than the width of the reagent kits 00, ensuring that the reagent kits 00 are placed in a single row within each slot. The slot openings face the first side, and the outlets 130 extend along the X-axis to connect with the openings of all placement slots. Each placement slot, facing the second side 110, is connected to a detection port 111 and an operation port 112. That is, all detection ports 111 are evenly spaced along the X-axis, and all operation ports 112 are also evenly spaced along the X-axis and opposite the outlet 130. Each placement slot contains a detection position, and each detection position is opposite a detection port 111. The vertical plates 141 have multiple second through holes 143 to reduce the weight of the storage mechanism. Further, in one embodiment, the two upright plates 141 at both ends are single-layered, while the multiple upright plates 141 near the middle are double-layered. Each layer of the upright plates 141 has a guide plate 142 at one end facing the first side, and the guide plate 142 is inclined. Each layer of each upright plate 141 has a guide plate 142 corresponding to its adjacent placement slot, such that the two guide plates 142 located on two adjacent different upright plates 141 form a trumpet-shaped structure at the opening of their adjacent placement slots to guide the reagent kit 00 into the placement slot. Of course, in other embodiments, the upright plates 141 at both ends and the upright plates 141 near the middle can both be single-layered, and two guide plates 142 are provided on both sides of the single-layer upright plate 141 near the middle; or the upright plates 141 at both ends and the upright plates 141 near the middle can both be double-layered. Here, no limitation is made.

[0069] The technical solution of this utility model embodiment, by dividing the receiving cavity into multiple placement slots, makes full use of space, and each placement slot holds only a single row of reagent kits 00, ensuring that the reagent kits 00 are placed in an orderly manner and are easy to manage. Each placement slot corresponds to a detection port 111 and an operation port 112, which can accurately detect whether there is a reagent kit 00 at the detection position of each placement slot, thereby accurately verifying the quantity of each row of reagent kits 00. At the same time, it is convenient to remind the recipient of reagent kits 00 in any placement slot to replenish, and ensures that the pusher structure 200 can accurately push out the placement slot containing reagent kits 00, thereby improving the reliability and accuracy of delivery.

[0070] Please see Figure 4 In one embodiment, the distance between the detection port 111 and the operation port 112, which are connected to the same placement slot, in the Z-axis direction is greater than or equal to the height of a single reagent kit 00.

[0071] Specifically, the distance between the detection port 111 and the operation port 112 in the Z-axis direction is greater than or equal to the total height of the three reagent kits 00. That is, the position of the fourth row of reagent kits 00 is the detection position, and the detection port 111 is opposite to the fourth row of reagent kits 00 to provide the operator with a replenishment buffer time. Of course, in other embodiments, the detection port 111 may also be opposite to the fifth or sixth row of reagent kits 00, and no specific limitation is made here. Among them, the detection port 111 being opposite to the fourth row of reagent kits 00 is the preferred embodiment, so as to reduce the replenishment frequency while providing a replenishment buffer time.

[0072] Please see Figure 4 In one embodiment, the storage mechanism of the reagent kit 00 further includes a reflective sensor 310 and a control module, which are disposed on the pusher structure 200. The reflective sensor 310 is able to be opposite to the detection port 111 to detect whether the reagent kit 00 is placed in the receiving cavity at the position opposite to the detection port 111. The control module is electrically connected to the reflective sensor 310 and the pusher structure 200.

[0073] Specifically, the pusher structure 200 can move the reflective sensor 310 in the X-axis direction. The reflective sensor 310 is located on the pusher structure 200 and above the component in the pusher structure 200 that performs the ejection of the reagent kit 00, so that the emitted light from the reflective sensor 310 can pass through any detection port 111. When the reflective sensor 310 receives reflected light, it indicates that the reagent kit 00 is placed at the detection position; when the reflective sensor 310 does not receive reflected light, it indicates that the reagent kit 00 is not at the detection position.

[0074] The reflective sensor 310 transmits the detection results to the control module via an electrical signal. The control module stores the total number of reagent kits 00 placed in each slot. During each ejection process, the control module controls the movement of the pusher structure 200 so that it aligns with one of the slots and ejects the reagent kits 00. The control module then calculates the number of remaining reagent kits 00 in that slot based on the number of times the pusher structure 200 operates. Simultaneously, the control module verifies and corrects the number of remaining reagent kits 00 in the slot based on the detection results of the reflective sensor 310. Specifically, after the bottom row of reagent kits 00 is pushed out, the reflective sensor 310 detects again through the detection port 111 whether a reagent kit 00 has fallen at the detection position. When no reagent kit 00 has fallen at the detection position, the control module can calculate the actual remaining quantity of reagent kits 00 in that row by subtracting one from the row number of the detection position, and compare it with the quantity of reagent kits 00 in that row recorded by the control module (the quantity of reagent kits 00 in that row recorded by the control module refers to the quantity of reagent kits in each row of placement slots that the operator will enter and register after replenishment. During the continuous delivery process, the number is deducted according to the number of pushes by the pusher structure). This realizes the verification of the quantity. If a difference is found between the actual remaining quantity and the quantity of reagent kits 00 in that row recorded by the control module, the actual remaining quantity is used for correction.

[0075] The control module stores alert quantities for when restocking is needed. In one embodiment, when the reflective sensor 310 detects that no reagent kit 00 is available at any detection position, the control module will prompt the operator to restock. In another embodiment, the control module will only prompt the operator to restock when the reflective sensor 310 detects that no reagent kits are available at N detection positions (N is greater than 1 and N is less than or equal to the number of placement slots; N can be flexibly set according to actual needs). The control module includes a processing unit and a controller, etc. The functions of the control module are mainly implemented through logic algorithms, which are not limited here.

[0076] The technical solution of this utility model embodiment, by setting a reflective sensor 310 and placing it on the pusher structure 200, enables the reflective sensor 310 to move during the movement of the pusher structure 200, allowing the reflective sensor 310 to accurately align with the detection port 111 for detection. By setting a control module, the movement stroke of the pusher structure 200 can be precisely controlled, and the remaining reagent kit quantity can be calculated and verified by combining the number of times the pusher structure 200 is pushed out and the detection signal of the reflective sensor 310, achieving intelligent management and further improving the reliability and accuracy of shipments.

[0077] Please see Figure 6 and Figure 7In one embodiment, the pusher structure 200 includes a push rod 210, a first drive unit, and a second drive unit. The push rod 210 is offset from and located below the reflective sensor 310. The first drive unit is driven to the push rod 210 to move the push rod 210 in the Y-axis direction. The second drive unit is driven to the first drive unit and the reflective sensor 310 to move the reflective sensor 310 and the first drive unit in the X-axis direction.

[0078] The control module is electrically connected to the first drive unit and the second drive unit. The reflective sensor 310 is located diagonally above the push rod 210. When the reagent kit 00 needs to be pushed out, the control module controls the second drive unit to drive the first drive unit to move the push rod 210 in the X-axis direction. Simultaneously, the second drive unit drives the reflective sensor 310 to move in the X-axis direction, so that the reflective sensor 310 is initially aligned with the detection port 111. After detecting the presence of the reagent kit 00 at the detection position, the control module controls the second drive unit to drive the first drive unit to move the push rod 210 a small distance in the X-axis direction, so that the push rod 210 is aligned with the operation port 112. Then, the control module controls the first drive unit to drive the push rod 210 to move along the Y-axis direction to pass through the operation port 112 and push the reagent kit 00 out of the outlet 130. Finally, after the ejection action is completed, the control module first controls the first drive unit to drive the push rod 210 to reset, and then controls the second drive unit to drive the first drive unit and the reflective sensor 310 to reset. During the reset process, the reflective sensor 310 can re-detect the detection position to determine whether the reagent kit 00 has fallen at the detection position. The length of the push rod 210 is equal to or slightly greater than the distance between the operating port 112 and the outlet 130 to ensure that the push rod 210 can smoothly eject the reagent kit 00.

[0079] Specifically, the push rod 210 includes a support portion 212 and a main body portion 211. The main body portion 211 is the part that mainly contacts the reagent kit 00. The support portion 212 connects the main body portion 211 and the first drive unit. The width of the support portion 212 is smaller than the width of the main body portion 211 and smaller than the width of the reagent kit 00. The bottom surface of the storage rack 100 is provided with a plurality of clearance openings 190 that correspond one-to-one with and communicate with a plurality of placement slots. The two ends of the clearance openings 190 are connected to the operation port 112 and the outlet 130, respectively. The width of the clearance openings 190 is adapted to the support portion 212 to avoid the support portion 212 and at the same time prevent the reagent kit 00 from falling directly from the clearance openings 190. Thus, by cooperating with the support part 212 and the clearance opening 190, when the main body part 211 enters the placement slot through the operation port 112, the support part 212 can simultaneously enter the clearance opening 190 to penetrate the storage rack 100. The clearance opening 190 can avoid the support part 212. The first drive unit drives the main body part 211 to move through the support part 212, avoiding the need for the push rod 210 to be suspended in the air to ensure that it can be inserted into the placement slot, which would result in an excessively long push-out and reset stroke of the push rod 210, thus achieving a reasonable layout.

[0080] Since there are multiple placement slots, in one embodiment, when it is necessary to push out the reagent kit 00, the control module controls the pusher structure 200 to push out the reagent kits 00 in the multiple placement slots sequentially. That is, the pusher structure 200 first pushes out the reagent kits 00 in one placement slot multiple times until the reflective sensor 310 detects that there is no reagent kit 00 in the detection position of that placement slot. The control system then reminds the operator to replenish the placement slot. The pusher structure 200 then pushes out the reagent kits 00 in another placement slot multiple times. In another embodiment, when it is necessary to push out the reagent kit 00, the control module controls the pusher structure 200 to push out the reagent kits 00 in the multiple placement slots sequentially until the reflective sensor 310 detects that there is no reagent kit 00 in the detection position of the last placement slot, reaching the warning quantity. The control system then reminds the operator to replenish the reagent kit. For example, if the detection finds that no reagent kit 00 has fallen in the first placement slot, the pusher structure 200 will immediately switch to the next placement slot until the last placement slot. At this time, all placement slots will still have three reagent kits 00 left, so as to prevent all placement slots from being emptied and to provide the operator with a replenishment buffer time.

[0081] Of course, in other embodiments, multiple reagent kits 00 in the placement slots can be pushed out in a predetermined order or in a random order. The number of warnings can also be flexibly set according to actual needs, and is not limited here.

[0082] Please see Figure 6 and Figure 7In one embodiment, the pusher structure 200 further includes a first mounting base 220 and a second mounting base 230 perpendicular to each other. The reflective sensor 310 is fixed to the first mounting base 220. The first drive unit includes a first connecting base 243 and a first power component 241. The first connecting base 243 is movably disposed on the first mounting base 220, and the push rod 210 is fixed to the first connecting base 243. The first power component 241 is disposed on the first mounting base 220 and is drivenly connected to the first connecting base 243. The second drive unit includes a second connecting base 252 and a second power component. The second connecting base 252 is movably disposed on the second mounting base 230, and the first mounting base 220 is fixed to the second connecting base 252. The second power component is disposed on the second mounting base 230 and is drivenly connected to the second connecting base 252.

[0083] Specifically, the first mounting base 220 and the second mounting base 230 are arranged perpendicularly and intersectingly. The first mounting base 220 extends along the Y-axis, and the second mounting base 230 extends along the X-axis. The second mounting base 230 is parallel to and spaced apart from the storage rack 100 in the Y-axis direction. The first connecting base 243 is slidably disposed on the side of the first mounting base 220 facing away from the second mounting base 230. The output shaft of the first power member 241 is driven to the first connecting base 243 through the first transmission member 242, so as to drive the first connecting base 243 to move the push rod 210 in the Y-axis direction. The second connecting base 252 is slidably disposed on the second mounting base 230. The side of the first connecting base 243 facing the second mounting base 230 is fixed to the second connecting base 252. The output shaft of the second power member is driven to the second connecting base 252 through the second transmission member 251, so as to drive the second connecting base 252 to move the first connecting base 243 and the push rod 210 in the X-axis direction. The first transmission component 242 and the second transmission component 251 can be configured as a synchronous pulley and synchronous belt structure, or as a connecting rod structure, etc.; the first power component 241 and the second power component can be configured as a motor or cylinder, etc., without limitation. Furthermore, both the first mounting base 220 and the second mounting base 230 are provided with linear guide rails 260, and both the first connecting base 243 and the second connecting base 252 are slidably mounted on the linear guide rails 260 to guide and position the movement of the first connecting base 243 and the second connecting base 252, making the movement of the push rod 210 more stable. Limiting components 270 are provided at both ends of the first mounting base 220 and the second mounting base 230, which can abut against the first connecting base 243 and the second connecting base 252 to limit the travel of the first connecting base 243 and the second connecting base 252. The limiting component 270 can be a protrusion or a bolt, etc., without limitation.

[0084] Please see Figure 4 , Figure 6 and Figure 7In one embodiment, the reagent kit 00 has an identification code on the side facing the second side 110. The storage mechanism of the reagent kit 00 also includes a barcode scanner 320 and a bracket 330. The barcode scanner 320 is used to scan the identification code through the operation port 112. The bracket 330 is vertically disposed on the first mounting base 220 and located on one side of the push rod 210. The barcode scanner 320 and the reflective sensor 310 are parallel and spaced apart on the bracket 330 along the Z-axis direction. When the reflective sensor 310 is opposite to the detection port 111, the barcode scanner 320 is opposite to the operation port 112.

[0085] The bracket 330 extends along the Z-axis and is located on the side of the first mounting base 220. The bracket 330 can move synchronously with the first mounting base 220 in the X-axis direction. The distance between the barcode scanner 320 and the reflective sensor 310 is equal to the distance between the operation port 112 and the detection port 111, ensuring that when the reflective sensor 310 is opposite to the detection port 111, the barcode scanner 320 is opposite to the operation port 112. The barcode scanner 320 and the push rod 210 are at the same height in the Z-axis direction, ensuring that both the barcode scanner 320 and the push rod 210 can be opposite to the operation port 112. Before the push rod 210 is opposite to the operation port 112, the barcode scanner 320 is first opposite to the operation port 112 to scan the identification code, facilitating subsequent traceability.

[0086] The technical solution of this utility model embodiment, by setting a barcode scanner 320 arranged parallel to the reflective sensor 310, enables the reflective sensor 310 and the barcode scanner 320 to be opposite to the detection port 111 and operation port 112 in the same placement slot, so that when the reflective sensor 310 is detecting, the barcode scanner 320 scans the reagent kit 00 simultaneously, avoiding the repetitive operation of the pusher structure 200 and improving work efficiency.

[0087] Please see Figure 6 and Figure 7 In one embodiment, the pusher structure 200 further includes a position detection unit disposed on the first mounting base 220 and the second mounting base 230, for detecting the position of the push rod 210 in the Y-axis direction and the X-axis direction.

[0088] Specifically, in one embodiment, the position detection unit includes a first photoelectric switch 411, a first baffle 412, a second photoelectric switch 421, and a second baffle 422. The first mounting base 220 is provided with a first photoelectric switch 411 at both ends in the Y-axis direction; the first baffle 412 is provided on the first connecting base 243 and is used to trigger any of the first photoelectric switches 411; the second mounting base 230 is provided with a second photoelectric switch 421 at at least one end in the X-axis direction; the second baffle 422 is provided on the second connecting base 252 and is used to trigger the second photoelectric switch 421.

[0089] When the baffle extends into the photoelectric switch, it can trigger the photoelectric switch. The photoelectric switch can output a real-time electrical signal to the control module, so that the control module can obtain the position information of the push rod 210 in the Y-axis direction and the X-axis direction, so as to control the first power component 241 and the second power component, and realize the control of the position of the push rod 210.

[0090] The first baffle 412 is located on the side of the first connecting seat 243 and protrudes from the first connecting seat 243 at both ends. The second baffle 422 is located on the side of the second connecting seat 252 and protrudes from the second connecting seat 252 at both ends. The end of the first mounting seat 220 away from the storage rack 100 in the Y-axis direction is the Y-axis origin, and the other end of the first mounting seat 220 in the Y-axis direction is the push-out position. Two first photoelectric switches 411 are respectively located at the Y-axis origin and the push-out position to detect whether the push rod 210 has reached the push-out position or returned to the initial position. The end of the second mounting seat 230 in the X-axis direction is the X-axis origin, and a second photoelectric switch 421 is located at the X-axis origin. In one embodiment, only one second photoelectric switch 421 is provided at the X-axis origin to detect whether the push rod 210 has reached the initial position on the X-axis. In another embodiment, a second photoelectric switch 421 is also provided at the other end of the second mounting seat 230 in the X-axis direction to detect whether the push rod has moved to the maximum distance in the X-axis direction.

[0091] Of course, in other embodiments, the position detection unit may also be configured as an infrared sensor, a through-beam photoelectric switch, or a fiber optic photoelectric switch, etc., without limitation.

[0092] The technical solution of this utility model embodiment, by setting a position detection unit, can detect whether the push rod 210 has been pushed out or reset, thereby providing a positioning point for the movement of the push rod 210, ensuring that the push rod 210 can be accurately positioned in each push-out and reset process, avoiding operational errors caused by position deviation, and improving the reliability of the pusher structure 200.

[0093] Please see Figures 1 to 3 In one embodiment, the storage mechanism of the reagent kit 00 further includes a door 500, with an opening on the first side communicating with the receiving cavity. The opening and the outlet 130 are spaced apart in the Z-axis direction. The door 500 is rotatably connected to the storage rack 100 to cover or expose the opening.

[0094] The opening is opposite to and connected to the openings of all placement slots, and the door 500 never obstructs the outlet 130. When the door 500 is rotated to reveal the opening, the operator replenishes the placement slots through the opening. When the door 500 is rotated to cover the opening, the door 500 can completely push the unplaced reagent kits 00 into the placement slots. One end of the door 500 is rotatably connected to the storage rack 100, and the other end of the door 500 is connected to the storage rack 100 via a push-button switch, so that the door 500 can be locked when the opening is covered, preventing accidental opening. When the door 500 is locked to the storage rack 100, its inner wall abuts against the end of the guide plate 142, so as to limit and support the upper row of reagent kits 00 during the process of pushing out the lower row of reagent kits 00, preventing the upper row of reagent kits 00 from tipping over. The door 500 is provided with a handle 510 to facilitate the operator to rotate the door 500.

[0095] In one embodiment, the door 500 is transparent and has size markings to facilitate rapid manual counting of the reagent kits 00. Further, in one embodiment, a baffle 150 is provided between the opening and the outlet 130. The height of the baffle 150 is greater than or equal to the height of a single reagent kit 00 to limit the reagent kits 00 in the second row or above, further preventing the reagent kits in the second row from being pulled out of the placement slot during the process of pushing out the bottom row of reagent kits 00. The baffle 150 and the door 500 can be integrally formed, i.e., the baffle 150 is the lower part of the door 500. Of course, in other embodiments, the baffle 150 can also be fixedly or detachably mounted on the storage rack 100; this is not limited here.

[0096] The technical solution of this utility model embodiment, by setting an opening and a door 500, facilitates the replenishment of goods by operators. The door 500 can cover the opening to provide protection for the reagent kit 00, which helps to achieve neat arrangement of the reagent kit 00 and prevents the reagent kit 00 from tipping over, avoiding displacement of the reagent kit 00 and improving the stability and reliability of the entire storage mechanism.

[0097] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
