Description

Technical Field

[0001] This invention relates to the field of detection and analysis equipment technology, and specifically to an automatic reaction cup sorting device. Background Technology

[0002] Sample analyzers (such as flow cytometers and chemiluminescence immunoassay analyzers) typically use disposable reaction cups for testing. The main function of an automatic reaction cup loading device is to automatically arrange the user-added bulk reaction cups neatly and transport the arranged reaction cups to the designated position for use by the testing system.

[0003] Traditional automatic reaction cup loading devices typically include a hopper, a picking mechanism, a reversing mechanism, and a transfer mechanism. The picking mechanism usually uses a picking block with a load-bearing surface, which is moved by a drive structure to pick up the reaction cup from the hopper and transport it to the unloading position where it falls. In actual use, the reaction cup may have difficulty falling smoothly from the picking block to the subsequent mechanism due to the large friction between its shape and the picking block, causing jamming and other malfunctions. To solve the above problems, patent document WO2019 / 056231A1 proposes a reaction cup picking mechanism that controls the drive structure to make the picking block stop and / or vibrate after moving a set distance or time, thereby prompting the reaction cup to fall from the picking block.

[0004] However, the above solution has certain limitations. First, the drive structure needs to achieve complex stepping, pausing, or forward / reverse jitter control, which places high demands on the control precision and reliability of the motor, increasing system complexity and the difficulty of the control program. Second, frequent jittering may accelerate the wear of mechanical parts and generate vibration and noise. Finally, this solution lacks precise monitoring of the supply status of the reaction cups in the hopper and cannot intelligently start and stop the picking action, which may lead to unstable picking efficiency or idling.

[0005] Therefore, a more stable, reliable, and simplified reaction cup autoloading technology is needed, which can avoid the use of complex pick-up block jitter mechanisms while ensuring efficient pick-up and reliable unloading. Summary of the Invention

[0006] To achieve stable, reliable, and simplified automatic loading of reaction cups, this invention provides an automatic reaction cup sorting device.

[0007] The first technical solution adopted in this invention is: an automatic reaction cup sorting device, comprising: a hopper assembly for storing reaction cups, divided into a large upper hopper and a small, open, tilted-to-one pick-up hopper at the bottom; a pick-up assembly, disposed on one side of the opening of the small pick-up hopper, including a lifting motor, two sprockets, and a tilting lifting chain connected by a drive mechanism; multiple pick-up blocks are spaced apart on the lifting chain, their lower ends penetrating the small pick-up hopper; each pick-up block has a laterally tilted load-bearing surface for supporting the reaction cup; the combination of the tilt angle of the lifting chain and the lateral tilt angle of the load-bearing surface is configured such that the reaction cup slides off the lower end of the load-bearing surface by gravity; and a top cup assembly. The component includes a top cup plate and a cam slider mechanism; the top cup plate is arranged inside the small pickup compartment, and its upper surface is approximately parallel to the load-bearing surface; there is a small gap between the top cup plate and the inner wall of the small pickup compartment, and between the top cup plate and the pickup assembly, configured to prevent the reaction cup from falling; the cam slider mechanism is drivenly connected to the lifting motor to drive the top cup plate to reciprocate along a direction parallel to the lifting chain; the reversing assembly has a downwardly angled groove for receiving the reaction cup that slides down from the pickup block and guiding the reaction cup to flip in a vertical plane; the transfer assembly is connected to the end of the groove and has at least one reaction cup position for receiving, storing and transferring the reaction cup.

[0008] Preferably, the large hopper has an inwardly inclined guide plate at the top opening, and a vibration motor is installed on the guide plate.

[0009] Preferably, the sprocket, the lifting chain, and the pickup block are disposed between two side fixing plates; one of the side fixing plates has an opening at the lower end of the load-bearing surface of the pickup block to form a material discharge port; a baffle plate is disposed between the two side fixing plates at the top bend of the lifting chain.

[0010] Preferably, the pickup block includes a rectangular body and oblique protrusions on its surface, the upper surface of the oblique protrusions forming the load-bearing surface, the body being fixed to the outer chain plate of the lifting chain, and at least one end of the oblique protrusions extending beyond the dimensional range of the body in the direction of travel.

[0011] Preferably, the installation angle α of the lifting chain relative to the vertical plane is 10° to 25°, and the lateral tilt angle β of the load-bearing surface relative to the direction of travel of the lifting chain is 45° to 55°.

[0012] Preferably, the cam-slider mechanism includes a cam, a connecting rod, a slider, a slide rail, and a connecting plate. The cam is coaxially mounted with the lifting motor and the lower-positioned sprocket. The slide rail is mounted parallel to the lifting chain on the outer wall of the side fixing plate. The slider slides in cooperation with the slide rail. The two ends of the connecting plate are respectively connected to the top cup plate and the slider. The middle part of the connecting plate is connected to the cam through the connecting rod.

[0013] Preferably, the commutation component has a generally Y-shaped guide slot, which is divided into a sliding and flipping area near the pickup component and a buffer area for buffering the reaction cup.

[0014] Preferably, the transfer assembly includes a mounting base, a rotating disk, and a transfer motor. The rotating disk is rotatably disposed in the mounting base, and at least one reaction cup position is provided on the outer peripheral wall of the rotating disk. An external inlet is provided on one side of the mounting base, and the external inlet is connected to the end of the buffer area. The transfer motor drives the rotating disk to rotate, so that the reaction cup position is aligned with the external inlet, so that the reaction cup enters the reaction cup position.

[0015] Preferably, the system also includes sensor components, including: a hopper upper limit sensor and a hopper lower limit sensor disposed within the large hopper; a chute upper limit sensor and a chute lower limit sensor disposed within the chute; and a reaction cup in-situ sensor and a reaction cup removal detection sensor disposed at the transfer assembly.

[0016] The second technical solution adopted in this invention is: a sample analyzer, including the automatic sorting device for reaction cups, and a transfer component for transferring the reaction cups from the transfer component to a subsequent work station.

[0017] The present invention has the following beneficial effects: 1. Simple picking and sorting process: By combining the lifting angle of the picking component with the lateral tilt angle of the picking block's load-bearing surface in a specific design, the reaction cup can reliably slide off the picking block under pure gravity. This eliminates the complex control logic that relies on motor stoppage or vibration in existing technologies to unload the cup, simplifies the control system, and reduces the failure rate. 2. High pickup rate and anti-jamming: The top cup assembly and the pickup assembly are linked synchronously. The reciprocating motion of the top cup plate in the hopper can continuously agitate the reaction cup, making it easier for it to fall into the pickup path. At the same time, it prevents the reaction cup from accumulating in dead corners of the hopper or getting stuck in the movement gap, thus improving the pickup success rate and smooth operation. 3. Automation and Reliability: It integrates a multi-level sensor monitoring system, realizing full-process monitoring and intelligent start-stop control from silo inventory and chute buffer status to transfer station, ensuring continuous, stable and orderly operation of the equipment, and can promptly alert in case of abnormalities.

Detailed Implementation

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] In the embodiments, such as Figures 1-8 The diagram shows an automatic reaction cup sorting device for a sample analyzer, comprising: a hopper assembly 1 for storing reaction cups 6, divided into a large upper hopper 1.1 and a small, open, tilted-to-one pick-up hopper 1.2 at the bottom; a pick-up assembly 2, located on one side of the opening of the small pick-up hopper 1.2, including a drive-connected lifting motor 2.1, two sprockets 2.2, and a tilting lifting chain 2.3, with multiple pick-up blocks 2.4 spaced apart on the lifting chain 2.3, the lower ends of which pass through the small pick-up hopper 1.2; each pick-up block 2.4 having a laterally tilted load-bearing surface 2.5 for supporting the reaction cups 6; the combination of the tilt angle of the lifting chain 2.3 and the lateral tilt angle of the load-bearing surface 2.5 is configured such that the reaction cups 6 slide off the lower end of the load-bearing surface 2.5 by gravity; and a top cup assembly 3, comprising a top cup plate 3.1 and... A cam-slider mechanism 3.2; a top cup plate 3.1 is arranged inside the small pickup bin 1.2, its upper surface being approximately parallel to the load-bearing surface 2.5; a small gap exists between the top cup plate 3.1 and the inner wall of the small pickup bin 1.2, and between it and the pickup assembly 2, configured to prevent the reaction cup 6 from falling; the cam-slider mechanism 3.2 is driven by the lifting motor 2.1 to drive the top cup plate 3.1 to slide back and forth in a direction parallel to the lifting chain 2.3; a reversing assembly 4 has a downwardly angled chute 4.1 for receiving the reaction cup 6 that slides down from the pickup block 2.4 and guiding the reaction cup 6 to flip in the vertical plane; a transfer assembly 5 is connected to the end of the chute 4.1 and has at least one reaction cup position 5.1 for receiving, storing, and transferring the reaction cup 6, which is transferred from the reaction cup position 5.1 to the subsequent work station via the transfer assembly. By dividing the hopper assembly 1 into a large hopper 1.1 and a small pickup bin 1.2, the initial diversion and concentration of the reaction cup 6 are achieved. The specific pitch angle of the lifting chain 2.3 in the pickup assembly 2, combined with the specific lateral tilt angle of the supporting surface 2.5 on the pickup block 2.4, ensures that the reaction cup 6 can slide off the supporting surface 2.5 purely by gravity when it reaches the top, eliminating the need for a complex electronic vibration control program, thus simplifying the control logic and improving reliability. The top cup plate 3.1 of the top cup assembly 3 is linked to the pickup action, continuously agitating the reaction cup 6 in the small pickup bin 1.2 to prevent it from stacking and assisting in feeding. The chute 4.1 of the reversing assembly 4 receives the sliding reaction cup 6 and flips it upright. The transfer assembly 5 completes the orderly reception and transfer. The entire device structure works in synergy, realizing a fully automated process from scattered stacking to orderly output.

[0029] In the embodiments, such as Figures 2-3As shown, an inwardly inclined guide plate 1.3 is provided at the opening above the large hopper 1.1, and a vibration motor 1.4 is installed on the guide plate 1.3. By setting the guide plate 1.3 and installing the vibration motor 1.4, the feeding inlet is effectively enlarged and the reaction cup 6 is guided to fall in. The vibration of the vibration motor 1.4 can prevent the reaction cup 6 from bridging or blocking at the hopper opening, ensuring that the material enters the small pick-up hopper 1.2 smoothly, thus improving the continuity and stability of the feeding.

[0030] In the embodiments, such as Figures 4-5 As shown, the sprocket 2.2, lifting chain 2.3, and pickup block 2.4 are positioned between two side fixing plates 2.6. One of the side fixing plates 2.6 has an opening at the lower end of the load-bearing surface 2.5 of the pickup block 2.4, forming a discharge port 2.7. A cup-stopping plate 2.8 is provided between the two side fixing plates 2.6, corresponding to the top bend of the lifting chain 2.3. The two side fixing plates 2.6 integrate the sprocket 2.2, lifting chain 2.3, and pickup block 2.4 into a stable frame, ensuring the operational accuracy of the pickup assembly 2. The discharge port 2.7 on the side fixing plate 2.6 provides a precise channel for the reaction cup 6 to slide down. The cup-stopping plate 2.8 at the top bend of the lifting chain 2.3 prevents the reaction cup 6 from getting stuck in the meshing part of the chain and sprocket or falling into the mechanism if it fails to slide down in time, avoiding potential mechanical jamming failures and significantly improving the operational reliability and lifespan of the equipment.

[0031] In the embodiments, such as Figure 6 As shown, the pickup block 2.4 includes a rectangular body 2.9 and a convex rib 2.10 on its surface. The upper surface of the convex rib 2.10 forms a load-bearing surface 2.5. The body 2.9 is fixed to the outer chain plate of the lifting chain 2.3. At least one end of the convex rib 2.10 extends beyond the dimensional range of the body 2.9 in the direction of travel. The pickup block 2.4 adopts an integrated structure of the body 2.9 and the convex rib 2.10. In particular, the extension of one end of the convex rib 2.10 beyond the dimensional range of the body 2.9 in the direction of travel allows for the formation of a load-bearing surface 2.5 with a longer effective length and a larger tilt angle on the fixed-size body 2.9. The larger lateral tilt angle provides a stronger lateral gravitational component to the reaction cup 6. The optimized geometric parameters of the functional surface within the limited installation space ensure a reliable and rapid slide after reaching the unloading position.

[0032] In the embodiments, such as Figure 6As shown, the installation angle α of the lifting chain 2.3 relative to the vertical plane is 10° to 25°, and the lateral tilt angle β of the bearing surface 2.5 relative to the traveling direction of the lifting chain 2.3 is 45° to 55°. The installation angle α provides sufficient vertical height, and the lateral tilt angle β ensures sufficient lateral sliding force. This combination of angles, through mechanical optimization, ensures that, under the common coefficient of friction between the reaction cup 6 and the bearing surface 2.5, the resultant force of gravity is sufficient to overcome static friction when the reaction cup 6 reaches the unloading position, achieving reliable self-weight sliding without any auxiliary unloading action.

[0033] In the embodiments, such as Figures 4-5 As shown, the cam-slider mechanism 3.2 includes a cam 3.3, a connecting rod 3.4, a slider 3.5, a slide rail 3.6, and a connecting plate 3.7. The cam 3.3 is coaxially mounted with the lifting motor 2.1 and the lower-positioned sprocket 2.2. The slide rail 3.6 is parallel to the lifting chain 2.3 and mounted on the outer wall of the side fixing plate 2.6. The slider 3.5 slides in conjunction with the slide rail 3.6. The two ends of the connecting plate 3.7 are connected to the top cup plate 3.1 and the slider 3.5, respectively. The middle part of the connecting plate 3.7 is connected to the cam 3.3 through the connecting rod 3.4. This transmission structure ensures that the reciprocating motion of the top cup plate 3.1 is strictly synchronized with the operation of the lifting chain 2.3, and the mechanical linkage is reliable. The movement trajectory of the top cup plate 3.1 is parallel to the pickup path, which can most effectively lift the reaction cup 6 onto the path of the pickup block 2.4, improving the pickup efficiency. Moreover, the entire mechanism has a compact structure, a single power source, and simplifies the system design.

[0034] In the embodiments, such as Figure 7 As shown, the chute 4.1 of the reversing assembly 4 has a roughly Y-shaped guide slot, divided into a sliding and flipping area 4.2 near the pickup assembly 2 and a buffer area 4.3 for buffering the reaction cups 6. The Y-shaped structure can accommodate possible positional deviations of the reaction cups 6 falling from the discharge port 2.7, increasing the receiving fault tolerance and ensuring that all reaction cups 6 can be reliably captured. Subsequently, the chute 4.1 guides the reaction cups 6 orderly from the sliding and flipping area 4.2 into the buffer area 4.3 for queuing, realizing a smooth transition from disordered falling to orderly arrangement.

[0035] In the embodiments, such as Figure 8As shown, the transfer assembly 5 includes a mounting base 5.2, a rotating disk 5.3, and a transfer motor 5.4. The rotating disk 5.3 is rotatably mounted in the mounting base 5.2, and its outer peripheral wall has at least one reaction cup position 5.1. An external inlet 5.5 is provided on one side of the mounting base 5.2, which connects to the end of the buffer zone 4.3. The transfer motor 5.4 drives the rotating disk 5.3 to rotate, aligning the reaction cup position 5.1 with the external inlet 5.5, so that the reaction cup 6 can enter the reaction cup position 5.1. By intermittently rotating the rotating disk 5.3 driven by the transfer motor 5.4, the empty reaction cup position 5.1 can be precisely aligned with the external inlet 5.5, thereby receiving the reaction cups 6 from the end of the buffer zone 4.3 one by one accurately, making the transfer process precise and reliable.

[0036] In the embodiments, such as Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, the system also includes sensor components, including: a hopper upper limit sensor S1 and a hopper lower limit sensor S2 installed in the large hopper 1.1; a chute upper limit sensor S3 and a chute lower limit sensor S4 installed in the chute 4.1; and a reaction cup in-situ sensor S5 and a reaction cup removal detection sensor S6 installed at the transfer assembly 5. The control system of the sorting device acquires various signals through the sensor components, thereby realizing the status monitoring of the entire process. Specifically, the system can determine the feeding demand based on the hopper upper limit sensor S1 and the hopper lower limit sensor S2 and provide an alarm; automatically control the start and stop of the picking assembly 2 to manage the buffer queue based on the chute upper limit sensor S3 and the chute lower limit sensor S4; and coordinate the rhythm of transfer and downstream processes based on the reaction cup in-situ sensor S5 and the reaction cup removal detection sensor S6. This achieves a high degree of automated operation and intelligent management, reduces manual intervention, and can promptly warn of abnormal states such as material shortage, full load, or jamming.

[0037] This embodiment serves as the pre-processing unit for the sample analyzer, providing the analyzer with consistently oriented and orderly arranged reaction cups 6 in a continuous, stable, and automatic manner. This enhances the automation level and processing throughput of the entire sample analyzer, reduces the preparation workload for operators, and, due to the high reliability of the sorting device itself, ensures the overall stability of the analyzer's operation and the continuity of test results.

[0038] Obviously, the above embodiments of the present invention are merely illustrative examples to illustrate the invention and are not intended to limit the implementation of the invention. Other obvious variations or modifications derived from the essential spirit of the invention still fall within the protection scope of the invention.
