Description

Technical Field

[0001] This invention belongs to the technical field of immunoassay analyzers, and specifically relates to an immunoassay analyzer reaction cup management device. Background Technology

[0002] Immunoassay analyzers are commonly used medical devices in clinical testing. They use reaction cups to hold test samples and reagents, complete the immune reaction, and then detect the signal, thereby enabling quantitative or qualitative analysis of antigens, antibodies, and other substances in human body fluids. Efficient and orderly management of the reaction cups is crucial for ensuring both testing efficiency and accuracy during the operation of an immunoassay analyzer.

[0003] In existing technologies, reaction cups in immunoassay analyzers are mostly fed manually or using simple vibration feeding methods. Manual feeding is inefficient and prone to contamination or misplacement of reaction cups due to operational errors. Vibration feeding methods suffer from problems such as reaction cup jamming and unstable feeding posture. When reaction cups accumulate at the outlet, blockages can occur, leading to feeding interruptions and affecting the continuity of the detection process. Furthermore, the existing feeding devices have poorly designed conveyor structures, causing reaction cups to tilt and fall during transport, and making it difficult to accurately transfer them to subsequent gripping stations, further reducing detection efficiency.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art described above. This invention provides an immunoassay analyzer reaction cup management device.

The conveying module is provided with multiple feeding blocks corresponding to the reaction cups, and the feeding blocks are provided with inclined surfaces corresponding to the reaction cups. A rotating cup assembly is connected to the upper end of the conveying module via a guide channel. The rotating cup assembly has multiple cup positions corresponding to the reaction cups, so that the reaction cups can be transferred from the guide channel to the gripping station by rotation. A stirring block is slidably assembled in the discharge port along the conveying direction parallel to the conveying module. The stirring block is provided with a push surface corresponding to the reaction cup. The stirring block reciprocates along the inclined direction of the conveying module through a driving mechanism, so as to push the reaction cup into the space between two adjacent feeding blocks.

[0007] Preferably, the feeding block includes a base plate and a protrusion. The base plate is connected to the conveying module, and the protrusion is disposed on the base plate. The protrusion is arranged at an angle to form the inclined surface of the corresponding reaction cup.

[0008] Preferably, the transmission module includes two parallel transmission chains, and a sprocket corresponding to the two transmission chains is provided at each end of the transmission module, one of the sprockets being connected to the first drive module. The base plate is fixedly connected to the transmission chain by bolts. The base plate is a square plate corresponding to the width of the transmission module. The base plates of any two adjacent feeding blocks are arranged side by side in the transmission direction of the transmission module to form a chain plate corresponding to the transmission chain.

[0009] Preferably, the end of the protrusion away from the guide channel has a smooth end, and a groove corresponding to the reaction cup is provided on the upper side of the protrusion.

[0010] Preferably, the rotating cup assembly includes a rotating base and a rotating body, the rotating body being rotatably connected inside the rotating base, and the rotating base having a notch on its side corresponding to the guide channel; The rotating body has multiple longitudinally extending strip grooves on its exterior as cup positions. The rotating body is driven by a second drive module so that when the cup position rotates to the guide channel, the reaction cup slides through the notch on the side of the rotating seat into the corresponding cup position.

[0011] Preferably, the inclination angle of the guide channel corresponds to the inclination angle of the feed block slope, and a first sensor corresponding to the reaction cup is provided on the side of the guide channel; The height of the cup position is less than the height of the reaction cup, and a second sensor corresponding to the reaction cup is provided above the rotary seat.

[0012] Preferably, the discharge port is a square structure corresponding to the conveying module, the stirring block is slidably assembled in the discharge port, and the bottom of the hopper transitions to the discharge port through a conical structure.

[0013] Preferably, the drive mechanism includes a swing arm and an eccentric wheel. The conveying module is provided with a housing. One end of the swing arm is hinged to the housing via a hinge shaft. The housing is provided with an inclined side corresponding to the conveying module. The other end of the swing arm is connected to a push plate via a hinge seat. The push plate is slidably assembled along the inclined side.

[0016] Beneficial Effects: By incorporating a hopper, conveyor module, rotating cup assembly, and stirring block, the system achieves automatic feeding, orderly conveying, and precise positioning of reaction cups without manual intervention, effectively improving feeding efficiency and ensuring the continuity of the immunoassay process. The stirring block, driven by the drive mechanism, reciprocates, pushing the reaction cups accumulated at the outlet one by one between adjacent feeding blocks, preventing blockage. The conveyor module's feeding blocks feature protrusions forming inclined surfaces and grooves that fit the reaction cups, effectively limiting and guiding them, ensuring stable posture during conveying and preventing tilting, falling, or deviation, thus improving conveying stability and accuracy. The rotating cup assembly, through the rotation of its rotating body, precisely transfers the reaction cups from the guide channel to the cup position and rotates them to the gripping station. Combined with the synergistic action of the first and second sensors, it achieves automated control of reaction cup transfer and positioning with high precision, effectively cooperating with the subsequent gripping mechanism and improving work efficiency.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] like Figure 1-4 As shown, an immunoassay analyzer reaction cup management device includes a hopper 1, a conveying module, a rotating cup assembly, a stirring block 4, and a driving mechanism. The hopper 1 is used to store reaction cups to be used. The bottom of the hopper 1 is provided with a discharge port 3. The hopper 1 is a cuboid structure with an open top and a narrow bottom. It is made of transparent acrylic material to facilitate observation of the remaining amount of reaction cups inside.

[0023] The lower end of the conveying module is located at the discharge port 3 of the hopper 1, and the upper end of the conveying module extends upward at an angle. Multiple feeding blocks 15 corresponding to the reaction cups are provided on the conveying module, and each feeding block 15 has an inclined surface corresponding to the reaction cup. The lower end of the conveying module is located directly below the discharge port 3 of the hopper 1, used to receive the reaction cups falling from the discharge port 3 and convey them upward. The upper end of the conveying module extends upward at an angle of 30°-60°, ensuring that the reaction cups will not slip due to excessive inclination during conveying, and effectively saving overall space. Multiple feeding blocks 15 corresponding to the reaction cups are provided on the conveying module, evenly spaced along the conveying direction of the conveying module. Each feeding block 15 has an inclined surface corresponding to the reaction cup, which is used to limit and guide the reaction cups, ensuring that the reaction cups maintain a stable posture during conveying and facilitating their introduction into the guide channel.

[0024] The rotating cup assembly is connected to the upper end of the conveying module via a guide channel. It is used to transfer the reaction cups conveyed to the top of the conveying module to the gripping station, so that the subsequent gripping mechanism (robotic arm) can grip the reaction cups and transfer them to the next inspection station. The rotating cup assembly has multiple cup positions 11 corresponding to the reaction cups. The multiple cup positions 11 are evenly distributed along the circumference of the rotating cup assembly. The rotating cup assembly rotates so that the cup positions 11 are aligned with the guide channel in sequence, so that the reaction cups are smoothly transferred from the guide channel to the corresponding cup positions 11. Then, the cup positions 11 containing the reaction cups are rotated to the gripping station. The rotating cup assembly has multiple cup positions 11 corresponding to the reaction cups. In this embodiment, there are 4 cup positions 11.

[0025] The stirring block 4 is slidably assembled into the discharge port 3 along the conveying direction (inclination angle) of the parallel conveying module. Its size is adapted to the internal size of the discharge port 3, allowing it to slide flexibly within the discharge port 3. The stirring block 4 is provided with a push surface corresponding to the reaction cup. The push surface is inclined, and its inclination angle is slightly larger than that of the feeding block 15, which facilitates the downward movement of the reaction cup. The stirring block 4 reciprocates along the inclined direction of the conveying module through a drive mechanism, thereby changing the state of the reaction cup at the bottom of the hopper 1. Through the pushing action, the reaction cups accumulated at the discharge port 3 are slid one by one between two adjacent feeding blocks 15, improving the cup loading efficiency.

[0026] In an optional embodiment, the loading block 15 includes a base plate and a protrusion. The base plate is connected to the conveying module and serves as the mounting base for the loading block 15. The base plate is made of a material with high strength and wear resistance, and can withstand the weight and friction of the reaction cup for a long time. The protrusion is integrally formed on the base plate. The cross-section of the protrusion is wedge-shaped, and one side of its inclined surface is a guide surface. The guide surface is inclined to the base plate, which facilitates the entry of the reaction cup between the protrusions. The protrusion is integrally formed with the base plate and is inclined to form an inclined surface corresponding to the reaction cup. The width of the inclined surface is slightly larger than the outer diameter of the reaction cup, ensuring that the reaction cup can be stably placed on the inclined surface and will not shift left or right during the conveying process.

[0027] Furthermore, the end of the protrusion furthest from the guide channel has a smooth end to prevent the end of the protrusion from scratching and damaging the reaction cup, while also facilitating the smooth sliding of the reaction cup into the inclined surface formed by the protrusion. A groove corresponding to the reaction cup is provided on the upper side of the protrusion. The cross-section of the groove is arc-shaped, and the radius of the arc is adapted to the outer diameter of the reaction cup flange, which can further limit the reaction cup and prevent it from slipping during the transfer process, ensuring the stability of the reaction cup during the transfer process.

[0028] The conveying module includes two parallel drive chains 14, symmetrically arranged on both sides of the conveying module. At each end of the conveying module, a sprocket corresponding to one of the two drive chains 14 is provided, with teeth on both ends of each sprocket corresponding to the two drive chains 14, thus meshing with them. One sprocket is connected to a first drive module, which uses a stepper motor. The output shaft of the stepper motor is connected to the shaft of the sprocket via a coupling, thereby achieving precise conveying of the reaction cup. A base plate is bolted to the drive chain 14. The base plate is a square plate corresponding to the width of the conveying module. The base plates of any two adjacent feeding blocks 15 are arranged side-by-side in the conveying direction of the conveying module to form chain plates corresponding to the drive chains 14, which enhances the overall strength of the conveying module and ensures the installation stability of the feeding blocks 15.

[0029] In another embodiment, the rotating cup assembly includes a rotating base 9 and a rotating body 10. The rotating body 10 is rotatably connected inside the rotating base 9, and the rotating base 9 has a notch on its side corresponding to the guide channel. The rotating body 10 has a cylindrical mounting cavity inside, and the rotating body 10 is rotatably connected to the mounting cavity of the rotating base 9 through a bearing. The rotating base 9 has a notch on its side corresponding to the guide channel, and the size of the notch is adapted to the size of the reaction cup to ensure that the reaction cup can smoothly pass through the notch from the guide channel into the cup position 11 of the rotating body 10.

[0030] In this embodiment, the guide channel includes two side plates 8 and a slide bar 16. The distance between the two side plates 8 is adapted to the reaction cup flange. The upper middle part of the adjacent side of the two side plates 8 is provided with a corresponding slide bar 16. The width between the slide bars 16 is adapted to the reaction cup. The side plates 8 are connected to the rotary seat 9. A gap is left between the end of the slide plate and the rotary seat 9. This gap is adapted to the outer diameter of the reaction cup flange. This allows the lower end of the reaction cup to rotate under the action of gravity and maintain a positive posture to pass through the notch and enter the corresponding cup position 11.

[0031] On the two side plates 8, there are baffles 12 on the side of the corresponding cup position 11 away from the guide channel. The baffles 12 extend vertically downward to block the upper end of the reaction cup and ensure that the reaction cup does not tilt when entering the cup position 11.

[0032] A full cup sensor is installed on the side of the conveying module away from the guide channel. When the number of reaction cups reaches the detection position, the cup feeding action is paused to prevent the number of cups stored from exceeding the threshold after continuous feeding. The channel is equipped with a cover to prevent the reaction cups from falling out of the channel during the downward movement.

[0033] The rotating body 10 has a cup-dropping channel in the middle, and a partition in the middle of the cup-dropping channel. Two waste bins are connected to the two sides of the partition through connecting pipes. The two waste bins are used to hold waste reaction cups and sample tubes, respectively.

[0034] The rotating body 10 has multiple longitudinally extending strip grooves on its exterior, serving as cup positions 11. The cross-section of the strip grooves is arc-shaped, and the radius of the arc matches the outer diameter of the reaction cup, ensuring that the reaction cup can fit tightly within the cup position 11 without wobbling. The multiple cup positions 11 are evenly distributed along the circumference of the rotating body 10, ensuring that the cup positions 11 can be precisely aligned with the guide channel during the rotation of the rotating cup assembly. The rotating body 10 is driven by a second drive module, which uses a servo motor. The output shaft of the servo motor is connected to the rotating shaft of the rotating body 10 through a reduction mechanism, which can precisely control the rotation angle and speed of the rotating body 10. When the cup position 11 rotates to the guide channel, the reaction cup slides through the notch on the side of the rotating seat 9 into the corresponding cup position 11, achieving precise transfer of the reaction cup.

[0035] In another embodiment, the guide channel is located at the downward-sloping end of the loading block 15. The inclination angle of the guide channel corresponds to the inclination angle of the loading block 15. Specifically, the angle of the slide bar 16 corresponds to the inclination angle of the loading block 15, ensuring that the reaction cup can remain stable when sliding from the loading block 15 of the conveying module into the guide channel. A first sensor 17 corresponding to the reaction cup is provided on the side of the guide channel. The first sensor 17 is a photoelectric sensor, and its sensing end faces the inside of the guide channel. It is used to detect whether there is a reaction cup passing through the guide channel. When a reaction cup is detected, a signal is sent to the control system. The control system controls the rotating cup assembly to rotate, so that the cup position 11 is aligned with the guide channel, ensuring that the reaction cup can slide smoothly. The reaction cup is positioned at cup position 11. The height of cup position 11 is less than the height of the reaction cup. Specifically, the height of cup position 11 is adapted to the length below the flange ring of the reaction cup, so that after the reaction cup enters cup position 11, its upper end can be exposed, which is convenient for the subsequent gripping mechanism to grip the reaction cup. A second sensor 18 corresponding to the reaction cup is provided above the rotary seat 9. The second sensor 18 is also a photoelectric sensor, and its sensing end faces the cup position 11 of the rotary body 10. It is used to detect whether there is a reaction cup in cup position 11. When a reaction cup is detected in cup position 11, a signal is sent to the control system. The control system controls the rotating cup assembly to rotate to the gripping station and controls the gripping mechanism to grip, thereby realizing automated control.

[0036] Furthermore, the discharge port 3 is a square structure corresponding to the conveying module, and its width is adapted to the width of the conveying module. The stirring block 4 is slidably assembled in the discharge port 3. The stirring block 4 and the inner wall of the discharge port 3 are fitted with a clearance, and the clearance is controlled at 0.1-0.3mm. This ensures that the stirring block 4 can slide flexibly, while avoiding the reaction cup from falling out of the gap due to excessive clearance. The bottom of the hopper 1 transitions to the discharge port 3 through a conical structure. The inner wall of the conical structure has a smooth surface, which facilitates the reaction cup in the hopper 1 to slide smoothly into the discharge port 3 under the action of gravity.

[0037] In another embodiment, the drive mechanism includes a swing arm 6 and an eccentric wheel 7. A housing 2, made of sheet metal, is provided outside the conveying module to protect internal components such as the conveying module and drive mechanism, and also serves to fix the module in place. One end of the swing arm 6 is hinged to the housing 2 via a hinge shaft. The housing 2 has a beveled edge corresponding to the conveying module for installation. The other end of the swing arm 6 is connected to a push plate 5 via a hinge seat, ensuring that the push plate 5 can slide along the beveled edge as the swing arm 6 swings. The upper end of the push plate 5 is fixedly connected to a stirring block 4 via bolts, ensuring a secure and convenient connection. For disassembly; one of the shafts (eccentric shaft) of the eccentric wheel 7 is connected to the middle of the swing arm 6 to ensure that the rotation of the eccentric wheel 7 can drive the swing arm 6 to swing around the hinge axis; the other shaft (central shaft) is connected to the third drive module, which uses a stepper motor to precisely control the rotation speed and rotation angle of the eccentric wheel 7; the rotation of the eccentric wheel 7 drives the swing arm 6 to swing back and forth, thereby driving the push plate 5 and the stirring block 4 to move back and forth along the inclined direction of the conveying module, so as to push the reaction cup at the discharge port 3 and avoid the reaction cup from accumulating and blocking.

[0038] Preferably, the hopper 1 has an opening on one side wall corresponding to the conveying module. The size of the opening is adapted to the width of the conveying module. The two sides of the opening are welded to the inclined sides of the housing 2 on both sides of the conveying module. By setting the opening, the upper end of the conveying module can extend into the hopper 1, which makes it easier for the feeding block 15 to receive the reaction cup falling from the discharge port 3, and further ensures the stability of the feeding process.

[0039] The upper part of the conveying module, corresponding to the upper part of the hopper 1, is provided with a discharge chamber 13. The discharge chamber 13 adopts a square cavity structure, and its material is the same as that of the housing 2. The width of the discharge chamber 13 is adapted to the conveying module. The bottom of the discharge chamber 13 extends to the hopper 1 to prevent the reaction cup from falling off. On the side of the discharge chamber 13 corresponding to the downward tilt of the material block 15, there is a through hole that connects to the guide channel. The size of the through hole is adapted to the outer diameter of the flange ring of the reaction cup. The cup full sensor is set on the side of the housing 2 away from the through hole. A guide nozzle is set at the through hole to ensure that the reaction cup can smoothly enter the guide channel through the through hole.
