Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a reaction cup storage mechanism and an automatic continuous loading device for reaction cups. Background Technology

[0002] In the field of medical devices, such as immunodiagnostic analyzers, reaction cups are typically needed to add samples and reagents for immunoassays. For fully automated immunodiagnostic analyzers, reaction cups are usually added to the reaction hopper using a tilting method, which automates the process and reduces operator workload. Related technologies typically include a loading device comprising a hopper, a cup-retrieving mechanism, a conveyor chute, and a buffer mechanism. The hopper holds a large number of reaction containers, which are then fed to a conveyor via the cup-retrieving mechanism and output to the buffer mechanism. The buffer mechanism orderly buffers the reaction containers, which are then removed by the retrieval mechanism. However, existing hopper structures often cause reaction cups to accumulate and become stuck inside the hopper, forming "dead cups" that hinder the cup-retrieving mechanism's loading. While existing solutions can reduce reaction cup accumulation by installing a vibration device outside the hopper, the effect is unsatisfactory, and this vibration may also affect the operation of other components of the loading device. Utility Model Content

[0003] One of the objectives of this utility model embodiment is to provide a reaction cup storage mechanism that can agitate the reaction cups in the hopper, keeping the reaction cups in an active state and preventing the reaction cups from accumulating and forming "dead cups".

[0008] As a further embodiment of the reaction cup storage mechanism, the agitator plate body is circular, one end of the protrusion extends along its length to the axis of the agitator plate body, and the other end of the protrusion extends along its length to the edge of the agitator plate body, with adjacent protrusions arranged at an included angle.

[0009] As a further embodiment of the reaction cup storage mechanism, the first driving component includes a first mounting base, a first motor, a first output shaft, a first optocoupler, and a sensing unit. The base plate has a mounting hole, and the stirring plate body is located within the mounting hole. The first mounting base is fixed to the bottom of the base plate. The first motor is mounted on the bottom of the first mounting base and is drively connected to the first output shaft. The first output shaft passes through the first mounting base and is fixedly connected to the bottom of the stirring plate body. The first motor can drive the first output shaft to rotate the stirring plate body. The first optocoupler is mounted on the side of the first mounting base facing the stirring plate body, and the sensing unit is mounted on the side of the stirring plate body facing the first mounting base. The stirring plate body can drive the sensing unit to rotate to the sensing area of ​​the first optocoupler.

[0010] As a further embodiment of the reaction cup storage mechanism, the base plate includes a first base plate and a second base plate that are inclined. The first base plate and the second base plate are connected at an angle of less than 180°. One side of the second base plate protrudes from the first base plate, making the base plate L-shaped. The discharge port is opened on the side of the second base plate that protrudes from the first base plate. The stirring plate is mounted on the first base plate adjacent to the second base plate. The first driving member is mounted on the bottom of the first base plate.

[0011] As a further embodiment of the reaction cup storage mechanism, the angle between the upper surface of the first base plate and the horizontal plane is ≥10°, and the angle between the upper surface of the second base plate and the horizontal plane is ≥10°.

[0012] As a further embodiment of the reaction cup storage mechanism, the area of ​​the first base plate is larger than the area of ​​the second base plate, the height of the second base plate protruding from the first base plate on one side is lower than the height of the lowest side of the first base plate, and the discharge port is provided on the lowest side of the second base plate.

[0013] As a further embodiment of the reaction cup storage mechanism, a feeding pusher is also included. The feeding pusher includes a second drive member, a first pusher block, and a second pusher block. The second drive member is installed outside the hopper and is pulsatorically connected to the first pusher block and the second pusher block, such that the first pusher block and the second pusher block are at least partially located inside the hopper.

[0016] Beneficial effects:

[0017] This invention installs a stirring plate inside a hopper, which is driven to rotate by a first driving component. This stirs the reaction cups stored in the hopper, keeping them in motion and preventing them from accumulating and becoming "dead cups." Simultaneously, by setting a first pusher and a second pusher within the hopper, the second driving component can drive the first pusher to push nearby reaction cups towards the second pusher, and drive the second pusher to push nearby reaction cups towards the discharge port. Furthermore, a second optocoupler is installed on the side plate adjacent to the first pusher to detect the presence of reaction cups near the first pusher. When the second optocoupler detects no reaction cups near the first pusher, it triggers a first motor to drive the stirring plate to rotate, moving at least some of the reaction cups in the hopper to the vicinity of the first pusher, thus avoiding continuous operation of the first motor and reducing energy consumption.

[0018] In the automatic continuous loading device for reaction cups of this invention, the above-mentioned reaction cup storage mechanism can improve the efficiency of loading reaction cups from the hopper to the cup retrieval mechanism. Attached Figure Description

[0034] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

[0038] like Figures 1 to 4As shown, this embodiment provides a reaction cup storage mechanism 200, including a hopper 210, a stirring plate 220, and a first driving member 230. The hopper 210 is mounted on the frame 100 and is used to store reaction cups. The stirring plate 220 is mounted inside the hopper 210. The first driving member 230 is mounted outside the hopper 210 and is connected to the stirring plate 220 for transmission. The first driving member 230 can drive the stirring plate 220 to rotate. The hopper 210 has an inlet and an outlet.

[0039] In this embodiment, the hopper 210 is used to store reaction cups. The stirring plate 220 is installed inside the hopper 210 and is driven to rotate by the first driving component 230. This stirs the reaction cups stored in the hopper 210, keeping them in an active state and preventing them from accumulating and becoming "dead cups." When the reaction cups in the hopper 210 are in an active state, it is beneficial for better feeding of the reaction cups and improves feeding efficiency.

[0040] Furthermore, the hopper 210 includes a bottom plate 211 and side plates 212 surrounding the outer periphery of the bottom plate 211, such as... Figure 2 The stirring plate 220 includes a stirring plate body 221 and a plurality of protrusions 222. The protrusions 222 are located on the upper surface of the stirring plate body 221. The stirring plate body 221 is mounted on the base plate 211 and is connected to the first driving member 230 for transmission. The base plate 211 and / or the side plate 212 are provided with a discharge port.

[0041] In this embodiment, the stirring plate body 221 is mounted on the base plate 211, and a plurality of protrusions 222 are provided on the upper surface of the stirring plate body 221. During the rotation of the stirring plate 220 driven by the first driving member 230, the protrusions 222 directly or indirectly collide with the reaction cup, thereby stirring the reaction cup.

[0042] Furthermore, the stirring plate body 221 is circular, one end of the protrusion 222 extends along its length to the axis of the stirring plate body 221, and the other end of the protrusion 222 extends along its length to the edge of the stirring plate body 221, with adjacent protrusions 222 arranged at an angle.

[0043] It is understandable that the protrusion 222 extends from the edge of the circular stirring plate body 221 to its axis. During the rotation of the stirring plate 220, the protrusion 222 can stir the reaction cup above the stirring plate body 221 as much as possible, thereby improving the stirring effect of the reaction cup.

[0044] For example, the included angle between two adjacent protrusions 222 is equal, and the protrusions 222 adopt a trapezoidal structure design that is narrower at the top and wider at the bottom, which can improve the uniformity of stirring of the reaction cup in the hopper 210. For example, there are four protrusions 222, and the included angle between two adjacent protrusions 222 is 90°.

[0045] Of course, the protrusion 222 in this embodiment is not limited to a straight strip structure, but can also be a curved structure, which can also play a good stirring effect on the reaction cup. The specific details will not be elaborated further.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the first driving component 230 includes a first mounting base 231, a first motor 232, a first output shaft, a first optocoupler 233, and a sensing unit 234. The base plate 211 has a mounting hole, and the stirring plate body 221 is located in the mounting hole. The first mounting base 231 is fixed to the bottom of the base plate 211. The first motor 232 is mounted on the bottom of the first mounting base 231 and is connected to the first output shaft. The first output shaft passes through the first mounting base 231 and is fixedly connected to the bottom of the stirring plate body 221. The first motor 232 can drive the first output shaft to rotate the stirring plate body 221. The first optocoupler 233 is mounted on the side of the first mounting base 231 facing the stirring plate body 221, and the sensing unit 234 is mounted on the side of the stirring plate body 221 facing the first mounting base 231. The stirring plate body 221 can drive the sensing unit 234 to rotate to the sensing area of ​​the first optocoupler 233. In this embodiment, the stirring plate body 221 is installed in the mounting hole, and the upper surface of the stirring plate body 221 is flush with the upper surface of the base plate 211. By installing the sensing part 234 on the back of the stirring plate body 221 and installing the first optocoupler 233 on the side of the first mounting base 231 for mounting the first motor 232 facing the stirring plate body 221, the sensing part 234 will block the signal reception of the first optocoupler 233 once for each rotation of the stirring plate body 221. By detecting the number of times the signal reception is blocked, the number of rotations of the stirring plate body 221 during intermittent rotation can be controlled.

[0047] Furthermore, such as Figure 2 As shown, the base plate 211 includes a first base plate 2111 and a second base plate 2112 that are inclined. The first base plate 2111 and the second base plate 2112 are connected at an angle of less than 180°. One side of the second base plate 2112 protrudes from the first base plate 2111, making the base plate 211 have an L-shaped structure. The second base plate 2112 has a discharge port on the side protruding from the first base plate 2111. The stirring plate 220 is installed on the first base plate 2111 adjacent to the second base plate 2112. The first driving member 230 is installed at the bottom of the first base plate 2111.

[0048] This embodiment features a special structural design for the base plate 211, which can accommodate more reaction cups compared to conventional silo structures. Furthermore, within the same volume, the silo 210 in this embodiment is lower in height, making it easier for operators to add reaction cups. By installing the stirring plate 220 on the first base plate 2111, the reaction cups agitated by the stirring plate 220 fall onto the second base plate 2112 and are discharged to the next workstation through the outlet on the second base plate 2112.

[0049] The term "the second base plate 2112 protruding from one side of the first base plate 2111" refers to the adjacent side of the first base plate 2111 and the second base plate 2112 that are connected.

[0050] Furthermore, the angle between the upper surface of the first base plate 2111 and the horizontal plane is ≥10°, and the angle between the upper surface of the second base plate 2112 and the horizontal plane is ≥10°. This angle design, combined with the function of the stirring plate 220, allows the reaction cup at the distal end to slide smoothly.

[0051] Furthermore, the area of ​​the first base plate 2111 is larger than the area of ​​the second base plate 2112, the height of the second base plate 2112 protruding from the first base plate 2111 is lower than the height of the lowest side of the first base plate 2111, and the lowest side of the second base plate 2112 is provided with a discharge port.

[0052] When the reaction cups accumulate at the junction of the first base plate 2111 and the second base plate 2112, the stirring action of the stirring plate 220 can cause the reaction cups to move toward the discharge port opened at the lowest point, namely the lowest side of the second base plate 2112.

[0053] Furthermore, the reaction cup storage mechanism 200 of this embodiment also includes a feeding pusher 250, which includes a second drive member 251, a first pusher block 252, and a second pusher block 253. The second drive member 251 is installed outside the hopper 210 and is connected to the first pusher block 252 and the second pusher block 253 in a transmission manner. The second drive member 251 causes the first pusher block 252 and the second pusher block 253 to be at least partially located inside the hopper 210. The second drive member 251 can drive the first pusher block 252 to push the reaction cup near the first pusher block 252 toward the second pusher block 253, and drive the second pusher block 253 to push the reaction cup near the second pusher block 253 toward the discharge port.

[0054] Under the action of the stirring plate 220, the reaction cups in the hopper 210 can be in an active state. In order to allow all reaction cups to slide smoothly to the discharge port to realize the feeding of the next station, a first pusher 252 and a second pusher 253 are added in this embodiment. The first pusher 252 is closer to the stirring plate 220, and the second pusher 253 is closer to the discharge port. Therefore, by driving the stirring plate 220 to rotate by the first motor 232, the reaction cups can slide to the vicinity of the first pusher 252. The second driving member 251 can drive the first pusher 252 to push the reaction cups near it to the vicinity of the second pusher 253. The second pusher 253 can then push the reaction cups near it to the discharge port under the action of the second driving member 251.

[0055] The second driving component 251 can drive the first push block 252 and the second push block 253 simultaneously or sequentially, without any specific restriction.

[0056] In this embodiment, the reaction cup storage mechanism 200 further includes a second optocoupler 240, which is mounted on a side plate 212 corresponding to the second base plate 2112. When the second optocoupler 240 does not detect a reaction cup, it triggers the first motor 232 to drive the stirring plate 220 to work, stirring the reaction cup in the hopper 210, causing the reaction cup to move towards the discharge port under the action of the stirring plate 220.

[0057] Furthermore, the second optocoupler 240 is mounted on the side plate 212 and adjacent to the first pusher block 252 to detect whether there are reaction cups near the first pusher block 252. When there are no reaction cups near the first pusher block 252, the first pusher block 252 is in a state of emptying. To avoid the first pusher block 252 doing useless work, when the second optocoupler 240 detects that there are no reaction cups near the first pusher block 252, it triggers the first motor 232 to drive the stirring plate 220 to rotate, so that at least some of the reaction cups in the hopper 210 move to the vicinity of the first pusher block 252, thereby avoiding continuous operation of the first motor 232 and reducing energy consumption.

[0058] Next, taking the synchronous operation of the first push block 252 and the second push block 253 driven by the second drive member 251 as an example, the feeding push member 250 of this embodiment will be described in detail.

[0059] Furthermore, the bottom plate 211 of the hopper 210 is provided with a first clearance hole and a second clearance hole spaced apart. The first push block 252 passes through the first clearance hole, and the second push block 253 passes through the second clearance hole. The second driving member 251 can drive the first push block 252 along its length direction ( Figure 7 The first pusher 252 moves back and forth in the direction indicated by the straight arrow, and the second drive unit 251 can drive the second pusher 253 along its length direction (in the direction indicated by the straight arrow). Figure 7The second push block 253 moves back and forth in the direction indicated by the straight arrow. The upper surface of the first push block 252 is a first inclined surface 2521 that slopes downward toward the second push block 253, and the upper surface of the second push block 253 is a second inclined surface 2531 that slopes downward toward the discharge port.

[0060] When the second driving member 251 drives the first pusher 252 to move upward along its length, the reaction cup that falls above the first pusher 252 slides to the second pusher 253 under the guidance of the first inclined surface 2521. When the second pusher 253 moves upward along its length, the reaction cup that falls above it slides to the discharge port under the guidance of the second inclined surface 2531, thereby realizing the smooth discharge of the reaction cup storage mechanism 200.

[0061] like Figure 7 and Figure 8 As shown, the first inclined surface 2521 has two parallel first sides 25211 and two parallel second sides 25212, wherein one first side 25211 is adjacent to the second push block 253 and lower than the other first side 25211, and one second side 25212 is adjacent to the wall of the hopper 210 and lower than the other second side 25212; the second inclined surface 2531 has two parallel third sides 25311 and two parallel fourth sides 25312, wherein one third side 25311 is adjacent to the first push block 252 and lower than the other third side 25311, and one fourth side 25312 is adjacent to the discharge port and lower than the other fourth side 25312.

[0062] By controlling the inclination of the first inclined plane 2521 and the second inclined plane 2531, the reaction cup located above the first inclined plane 2521 can be quickly slid across the first inclined plane 2521 to the vicinity of the second inclined plane 2531. When the second pusher block 253 descends, the reaction cup between the first pusher block 252 and the second pusher block 253 slides onto the second inclined plane 2531. When the second pusher block 253 rises, the reaction cup above the second inclined plane 2531 quickly slides to the discharge port, further improving the efficiency of the reaction cup loading and preventing the reaction cup from accumulating at the discharge port.

[0063] In this embodiment, the distance between the first pusher block 252 and the second pusher block 253 is less than the length of the reaction cup. By controlling the distance between the first pusher block 252 and the second pusher block 253 within this range, the reaction cup can be prevented from getting stuck between the first pusher block 252 and the second pusher block 253.

[0064] Furthermore, the first pusher block 252 and the second pusher block 253 are mounted on the second base plate 2112, that is, the first clearance hole and the second clearance hole are respectively opened on the second base plate 2112, and the discharge port is located on the second base plate 2112, and the discharge port is connected to the second clearance hole. Since the stirring plate 220 is mounted on the first base plate 2111, part of the reaction cup moves to the second base plate 2112 under the action of the stirring plate 220, and slides to the second pusher block 253 under the action of the first pusher block 252, and slides directly into the discharge port from the second inclined surface 2531 of the second pusher block 253.

[0065] In this embodiment, the first clearance hole and the second clearance hole respectively extend partially to the side plate 212 located on the outer periphery of the second base plate 2112, and the end of the side plate 212 away from the second base plate 2112 is inclined upward in the direction away from the second base plate 2112.

[0066] Furthermore, the feeding pusher 250 also includes a connecting block 254 and a first transmission assembly 255. The connecting block 254 is located below the base plate 211. The bottom of the first pusher 252 is connected to the bottom of the second pusher 253 through the connecting block 254. The connecting block 254 extends to the side of the second pusher 253 that is away from the first pusher 252. The second drive member 251 is fixed below the base plate 211 and connected to the connecting block 254 through the first transmission assembly 255.

[0067] It is understood that the bottom of the first pusher 252 and the bottom of the second pusher 253 are fixedly connected by the connecting block 254, and the second driving member 251 is connected to the connecting block 254 through the first transmission assembly 255. This allows the second driving member 251 to drive the first transmission assembly 255, which in turn drives the first pusher 252 and the second pusher 253 to move synchronously up and down. When the second driving member 251 drives the first pusher 252 and the second pusher 253 to descend, neither the first inclined surface 2521 nor the second inclined surface 2531 protrudes from the upper surface of the second base plate 2112. At this time, the reaction cup can move above the first inclined surface 2521, or even above the second inclined surface 2531, under the action of the stirring plate 220. When the second driving member 251 drives the first pusher 252 and the second pusher 253 to rise, the reaction cup slides along the first inclined surface 2521 towards the second pusher 253, and the reaction cup on the second inclined surface 2531 slides along the second inclined surface 2531 towards the discharge port.

[0068] For example, the first pusher 252 and the second pusher 253 are inclined and parallel to each other. Specifically, the first pusher 252 and the second pusher 253 are parallel to the cup-scooping mechanism 300, which facilitates pushing the reaction cup above the cup-scooping mechanism 300.

[0069] The hopper 210 in this embodiment also includes a first sleeve 213 and a second sleeve 214 located at the bottom of the second base plate 2112. The first sleeve 213 is connected to the first clearance hole, and the second sleeve 214 is connected to the second clearance hole. The first push block 252 passes through the first sleeve 213, and the second push block 253 passes through the second sleeve 214. Through the limiting effect of the first sleeve 213 and the second sleeve 214, the reciprocating movement stability of the first push block 252 and the second push block 253 can be further improved.

[0070] Furthermore, such as Figure 1 As shown, the first transmission assembly 255 includes a first transmission plate 2551, a second transmission plate 2552, and a connecting shaft 2553. The second drive component 251 includes a second motor and a second output shaft. The second motor is connected to the second output shaft, and the second output shaft is fixedly connected to the first transmission plate 2551. The connecting shaft 2553 is parallel to the second output shaft and connected to the first transmission plate 2551. The second transmission plate 2552 has an elongated hole 25521. The length direction of the elongated hole 25521 is perpendicular to the axial direction of the second output shaft and the moving direction of the first push block 252. The connecting shaft 2553 passes through the elongated hole 25521. The second transmission plate 2552 is fixedly connected to the connecting block 254.

[0071] When the second motor drives the second output shaft to rotate the first transmission plate 2551 around the axis of the second output shaft, the connecting shaft 2553 moves within the elongated hole 25521, simultaneously driving the second transmission plate 2552 to reciprocate. Figure 5 and Figure 6 This enables the first pusher block 252 and the second pusher block 253 to reciprocate along their length.

[0072] Furthermore, the storage mechanism 200 also includes a guide assembly 260, which includes a slide rail and a slider. The slide rail extends along the length of the first push block 252, and the slider has a groove that slides in conjunction with the slide rail. The slide rail is mounted on the outside of the cup-scooping mechanism 300 or on another support, and the slider is fixed to the second transmission plate 2552. The second motor drives the feeding pusher 250 to move under the guidance of the guide assembly 260, which can further improve the movement stability of the first push block 252 and the second push block 253.

[0073] In this embodiment, the first push block 252, the second push block 253, and the connecting block 254 are integrally formed structures.

[0074] This embodiment also provides an automatic continuous loading device for reaction cups, such as... Figure 1The system includes a frame 100 and a storage mechanism 200, a cup-retrieving mechanism 300, a conveying mechanism 400, and a buffer mechanism 500, which are sequentially mounted on the frame 100 along the conveying direction of the reaction cups. The storage mechanism 200 is a reaction cup storage mechanism 200 of any of the above embodiments, used to store reaction cups and supply reaction cups to the cup-retrieving mechanism 300. The cup-retrieving mechanism 300 extends to the outlet of the storage mechanism 200 and is used to transfer the reaction cups in the storage mechanism 200 to the conveying mechanism 400. The outlet of the conveying mechanism 400 is connected to the buffer mechanism 500.

[0075] In the storage mechanism 200, the reaction cup slides down the second inclined plane 2531 into the cup retrieval mechanism 300, and is then transferred by the cup retrieval mechanism 300 to the conveying mechanism 400. The cup retrieval mechanism 300 and the storage mechanism 200 share the second driving component 251.
