Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic automation equipment, and in particular to a reaction container loading device and diagnostic equipment. Background Art

[0002] During use, automated in vitro diagnostic equipment requires reaction containers to carry samples and reagents. The reaction containers are generally automatically loaded through a loading device.

[0003] Currently, loading devices generally use chain transmission mechanisms to load reaction vessels. However, due to the inherent characteristics of chain transmission, chain transmission mechanisms occupy a large space and are prone to causing the reaction vessels to become stuck, resulting in poor reliability of the loading device. Summary of the Invention

[0004] In view of this, the present invention provides a reaction vessel loading device and diagnostic equipment to solve the problem that the loading device adopts a chain transmission mechanism, occupies a large space and has poor reliability.

[0005] In a first aspect, the present invention provides a reaction vessel loading device, comprising:

[0006] A hopper with a feed port at the top and an opening at the bottom;

[0007] a partition, fixedly disposed in the hopper, dividing the opening into a first sub-opening and a second sub-opening;

[0008] A drive assembly is provided at the lower end of the hopper;

[0009] The pushing member and the loading assembly are respectively connected to the driving assembly and are located on opposite sides of the partition. The driving assembly drives the pushing member to move up and down and pass through the first sub-opening to lift the reaction container. The driving assembly simultaneously drives the loading assembly to move up and down and pass through the second sub-opening to receive the reaction container lifted by the pushing member.

[0010] Beneficial effects: The reaction vessel loading device of the present invention carries multiple reaction vessels through a hopper, and uses a driving assembly to drive a pusher to move upward through a first sub-opening, lifting the reaction vessel to the loading assembly. The reaction vessel falls to the loading assembly under the obstruction of a partition. The driving assembly can also drive the loading assembly to move upward through a second sub-opening and receive the reaction vessel. Afterwards, the driving assembly drives the loading assembly to descend and bring the reaction vessel to the next process. The driving assembly simultaneously drives the pusher and the loading assembly to move up and down synchronously repeatedly, thereby realizing continuous transportation of the reaction vessels. This simplifies the overall structure of the reaction vessel loading device, occupies less space, and adopts a continuous up and down movement method to transport the reaction vessels, which is highly reliable.

[0011] In an optional embodiment, the drive assembly includes:

[0012] A support is fixedly arranged at the bottom of the hopper, and a roller is respectively provided at the upper and lower ends of one side thereof;

[0013] A driving member is fixed on the support, and a driving shaft of the driving member is connected to one of the rollers;

[0014] The conveyor belt is sleeved between the two rollers and connected to the pushing member.

[0015] Beneficial Effects: The support supports the drive element and conveyor belt. The drive element drives the roller, which in turn drives the conveyor belt, which in turn drives the pusher element up and down, continuously lifting multiple reaction vessels and feeding them into the loading assembly. The drive assembly uses a conveyor belt instead of a traditional conveyor chain, which occupies less space, reduces costs, and improves reliability.

[0016] In an optional embodiment, the pusher is provided with a clamping portion for clamping the conveyor belt.

[0017] Beneficial effects: The pusher clamps the conveyor belt through the clamping part to achieve a fixed connection with the conveyor belt, and can move up and down with the forward and reverse rotation of the conveyor belt, and the movement is smooth.

[0018] In an optional embodiment, the support is provided with an end surface of the roller and is also provided with a guide rail extending in the up-down direction, and the pusher is correspondingly provided with a slider slidably connected to the guide rail.

[0019] Beneficial effect: The pusher is slidably connected to the guide rail on the support through the slider, which can further improve the reliability of the drive component and avoid the reaction container from getting stuck.

[0020] In an optional embodiment, the feeding assembly includes:

[0021] a pair of guide bars, disposed oppositely between the inner wall of the hopper and the partition;

[0022] A slide bar, fixedly connected to the pusher through a connecting plate, and disposed between the pair of guide bars, capable of moving up and down along the pair of guide bars;

[0023] A pair of baffles are arranged on the slide bar opposite to each other, and together with the slide bar and one of the guide bars opposite to the slide bar, form a receiving space for receiving the reaction container.

[0024] Beneficial Effect: After being lifted, the reaction vessel, blocked by a partition, enters the storage space enclosed by a pair of baffles, a slide, and guide bars. Because the slide is fixedly connected to the pusher via a connecting plate, the slide and the pair of baffles, driven by the drive assembly, rise to their maximum height. Then, driven downward by the drive assembly, the reaction vessel is ejected after reaching its lowest point. As the drive assembly drives the slide and the pair of baffles downward, the reaction vessel, influenced by gravity, flips and aligns within the storage space, descending to its lowest point before flowing to the next process step.

[0025] In an optional embodiment, a pair of the guide bars extend from the second sub-opening to the lower end of the hopper, and the loading assembly further includes an extension plate provided at the lower end of the hopper, wherein the extension plate is spaced apart from the partition and fixedly connected to the pair of the guide bars.

[0026] Beneficial effect: By arranging the extension plate and cooperating with the pair of extended guide bars, the reaction container moving up and down can be protected.

[0027] In an optional embodiment, a plurality of protrusions are provided at intervals on the inner wall of the guide bar opposite to the sliding bar.

[0028] Beneficial effect: During the descent process, the reaction container can automatically flip and correct by colliding with the protrusions on the inner wall of the guide bar, thereby further arranging the reaction containers and preventing the reaction containers from getting stuck.

[0029] In an optional embodiment, a downwardly inclined sub-guide bar is provided on the top of the guide bar opposite to the sliding bar.

[0030] Beneficial effect: By providing the sub-guide bar, the reaction container can be guided downward into the loading assembly.

[0031] In an optional embodiment, the top of the partition is lower than the feed port, and the top of the partition and the side wall opposite to the hopper form a discharge port. Driven by the driving assembly, the pushing member pushes the reaction container at least to the height of the discharge port.

[0032] Beneficial effect: The top of the partition is lower than the feed port to prevent the reaction container from separating from the hopper from the feed port. The driving component drives the pusher to lift the reaction container to the maximum position, and then enters the loading component from the discharge port.

[0033] In a second aspect, the present invention further provides a diagnostic device, comprising: the above-mentioned reaction vessel loading device.

[0034] Beneficial effects: Since the diagnostic equipment includes a reaction vessel loading device, it has the same effects as the reaction vessel loading device and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0047] The following combination Figures 1 to 8 , describing embodiments of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a reaction vessel loading device is provided, which mainly includes: a hopper 1, a partition 2, a drive assembly 3, a pusher 4 and a loading assembly 5. A feed port 101 is provided at the top of the hopper 1, and an opening 102 is provided at the bottom. The partition 2 is fixedly arranged in the hopper 1, dividing the opening 102 into a first sub-opening 1021 and a second sub-opening 1022. The drive assembly 3 is arranged at the lower end of the hopper 1. The pusher 4 and the loading assembly 5 are respectively connected to the drive assembly 3 and are located on opposite sides of the partition 2. The drive assembly 3 drives the pusher 4 to move up and down and pass through the first sub-opening 1021 to lift the reaction vessel 6 and bypass the partition 2. The drive assembly 3 simultaneously drives the loading assembly 5 to move up and down and pass through the second sub-opening 1022 to receive the reaction vessel 6 lifted by the pusher 4.

[0049] The reaction vessel loading device provided by the embodiment of the present invention carries multiple reaction vessels 6 through the hopper 1, uses the driving component 3 to drive the pushing member 4 to move upward through the first sub-opening 1021, and lifts the reaction vessel 6 to the loading component 5. Under the obstruction of the partition 2, the reaction vessel 6 falls to the loading component 5. The driving component 3 can also drive the loading component 5 to move upward through the second sub-opening 1022 and receive the reaction vessel 6. After that, the driving component 3 drives the loading component 5 to descend and bring the reaction vessel 6 to the next process. By driving the pushing member 4 and the loading component 5 to move up and down synchronously and repeatedly by the driving component 3, the continuous conveying of the reaction vessel 6 is realized, which simplifies the overall structure of the reaction vessel loading device, occupies less space, and adopts a continuous up and down movement method to convey the reaction vessel 6, which is more reliable.

[0050] Specifically, if Figure 1 and Figure 6 As shown, the hopper 1 is a bell-mouthed structure with a large opening at the top serving as the feed port 101 and a small opening at the bottom serving as the opening 102. A partition 2 is secured within the hopper 1 by fasteners. Reaction vessels 6 accumulate at the bottom of the hopper 1 under the force of gravity and are continuously lifted upward by a pusher 4. Blocked by the partition 2, they enter the loading assembly 5. The pusher 4 can be a pusher plate with a rolling roller mounted on top. The roller is in direct contact with the reaction vessels 6 to protect them.

[0051] It should be noted that the pusher 4 and the loading assembly 5 of the embodiment of the present invention can be directly connected to the drive assembly 3 or indirectly connected to the drive assembly 3. For example, the pusher 4 is directly connected to the drive assembly 3, and the loading assembly 5 is fixedly connected to the pusher 4. The drive assembly 3 directly drives the pusher 4 to move up and down, and indirectly drives the loading assembly 5 to move up and down through the pusher 4, that is, an indirect connection is achieved between the loading assembly 5 and the drive assembly 3.

[0052] In addition, the embodiment of the present invention does not limit the structure of the driving component 3, and any existing structure can be selected as needed.

[0053] In one embodiment, Figures 2 to 5 As shown, the drive assembly 3 primarily comprises a support 301, a drive member 303, and a conveyor belt 304. The support 301 is fixed to the bottom of the hopper 1, with a roller 302 positioned at each end of one side. The drive member 303 is fixed to the support 301, with its drive shaft connected to one of the rollers 302. The conveyor belt 304 is positioned between the two rollers 302 and connected to the pusher 4. The drive member 303 can be a motor.

[0054] The support 301 of the embodiment of the present invention is used to support the drive member 303 and the conveyor belt 304. The drive member 303 drives the roller 302 to rotate, which in turn drives the conveyor belt 304 to rotate. The conveyor belt 304 then drives the pusher 4 to move up and down, thereby continuously lifting multiple reaction vessels 6 and feeding them into the loading assembly 5. The drive assembly 3 uses the conveyor belt 304 instead of the traditional conveyor chain structure, which occupies less space, reduces costs, and improves reliability.

[0055] In addition, compared with the traditional conveyor chain structure, the embodiment of the present invention also designs the pushing member 4 and the loading assembly 5 separately, and uses the same driving member 303 to drive the two to move up and down synchronously, which simplifies the overall structure, occupies less space, has lower manufacturing costs, and is more reliable.

[0056] It should be noted that the embodiment of the present invention does not limit the method of fixing the support 301 to the hopper 1. A snap-fit ​​structure can be used for quick installation and removal, or a fastener-type structure can be used to improve fastening. For example, a support plate is fixed to the top of the support 301 via fasteners. The support plate is mounted on the bottom of the hopper 1 and is fixed to the hopper 1 via fasteners. The fasteners can be conventional fasteners such as screws and bolts.

[0057] Furthermore, in one embodiment, Figure 5 and Figure 8As shown, the pusher 4 is provided with a clamping portion 401 for clamping the conveyor belt 304. The pusher 4 clamps the conveyor belt 304 through the clamping portion 401, thereby achieving a fixed connection with the conveyor belt 304 and being able to move up and down with the forward and reverse rotation of the conveyor belt 304, with stable movement.

[0058] It should be noted that the embodiment of the present invention does not limit the structure of the clamping portion 401, as long as the clamping portion 401 can clamp the conveyor belt 304 to achieve a fixed connection between the pusher 4 and the conveyor belt 304. For example, the pusher 4 can extend from one side of the conveyor belt to form a pair of clamping plates, which are clamped to the conveyor belt 304. The forward and reverse rotation of the conveyor belt 304 drives the pair of clamping plates and the pusher 4 to move up and down.

[0059] Furthermore, in one embodiment, Figure 7 As shown, the end surface of the support 301 provided with the roller 302 is also provided with a guide rail 305 extending in the vertical direction, and the pusher 4 is correspondingly provided with a slider 402 that is slidably connected to the guide rail 305. The pusher 4 is slidably connected to the guide rail 305 on the support 301 via the slider 402, which can further improve the reliability of the drive assembly 3 and prevent the reaction container 6 from getting stuck.

[0060] Since the loading assembly 5 also needs to transport the reaction container 6 to the next process, in order to reduce the space occupied by the driving assembly 3 in the downstream mechanism of the loading assembly 5, the loading assembly 5 of the embodiment of the present invention is fixedly connected to the pushing piece 4, and the pushing piece 4 is directly fixed to the conveyor belt 304.

[0061] In one embodiment, Figure 8 As shown, the loading assembly 5 mainly includes: a pair of guide bars 501, a slide bar 502, and a pair of baffles 504. The pair of guide bars 501 are arranged relative to each other between the inner wall of the hopper 1 and the partition 2. The slide bar 502 is fixedly connected to the pusher 4 through the connecting plate 503 and is arranged between the pair of guide bars 501, and can move up and down along the pair of guide bars 501. The pair of baffles 504 are arranged relative to the slide bar 502, and together with the slide bar 502 and a guide bar 501 opposite to the slide bar 502, form a storage space for accommodating the reaction container 6. The pair of guide bars 501, the inner wall of the hopper 1, and the partition 2 form a channel for the slide bar 502 and the pair of baffles 504 to slide up and down.

[0062] After being lifted up, the reaction vessel 6 of the embodiment of the present invention enters the storage space surrounded by the pair of baffles 504, the slide 502, and the guide bar 501 under the obstruction of the partition 2. Since the slide 502 is fixedly connected to the pusher 4 via the connecting plate 503, the slide 502 and the pair of baffles 504 are also driven by the drive assembly 3 to rise to the maximum height. Afterwards, they move downward under the drive assembly 3, and after descending to the lowest point, the reaction vessel 6 is sent out. During the process of the drive assembly 3 driving the slide 502 and the pair of baffles 504 to move downward, the reaction vessel 6 is affected by gravity and flipped and aligned in the storage space. After descending to the lowest point, it flows to the next process.

[0063] Furthermore, in one embodiment, Figure 5 and Figure 8 As shown, a pair of guide bars 501 extend from the second sub-opening 1022 to the lower end of the hopper 1. The loading assembly 5 further includes an extension plate 505 disposed at the lower end of the hopper 1. The extension plate 505 is spaced apart from the partition plate 2 and fixedly connected to the pair of guide bars 501. The extension plate 505 is also fixedly connected to the bottom of the hopper 1. By providing the extension plate 505 and cooperating with the pair of extended guide bars 501, the reaction vessel 6 can be protected as it moves up and down.

[0064] Specifically, the extension plate 505, the partition plate 2 and the pair of guide bars 501 constitute another slideway for the slide bar 502, the pair of baffles 504 and the reaction container 6 to move up and down at the lower end of the hopper 1, and the two slideways are connected.

[0065] Furthermore, in one embodiment, Figure 8 As shown, the inner wall of the guide bar 501 opposite the slide bar 502 is provided with a plurality of protrusions 506 at intervals. During the descent process, the reaction container 6 collides with the protrusions 506 on the inner wall of the guide bar 501, thereby automatically turning over and correcting, further ensuring the alignment of the reaction containers 6 and preventing the reaction containers 6 from getting stuck.

[0066] It should be noted that the embodiment of the present invention does not limit the shape of the protrusion 506. For example, the protrusion 506 may be arc-shaped, spherical, cylindrical, etc.

[0067] Furthermore, in one embodiment, Figure 8 As shown, the top of the guide bar 501 opposite to the slide bar 502 is provided with a downwardly inclined sub-guide bar 507. By providing the sub-guide bar 507, the reaction container 6 can be guided downwardly into the loading assembly 5.

[0068] In one embodiment, Figure 1As shown, the top of the partition 2 is lower than the feed inlet 101. The top of the partition 2 and the side wall opposite the hopper 1 form a discharge port 103. Driven by the drive assembly 3, the pusher 4 pushes the reaction vessel 6 up to at least the height of the discharge port 103. The top of the partition 2 is lower than the feed inlet 101 to prevent the reaction vessel 6 from escaping from the hopper 1 through the feed inlet 101. The drive assembly 3 drives the pusher 4 to lift the reaction vessel 6 to its maximum position, and then the reaction vessel enters the loading assembly 5 through the discharge port 103.

[0069] The working principle of the embodiment of the present invention is as follows:

[0070] like Figure 1 As shown, reaction vessels 6 are placed in hopper 1. At least one reaction vessel 6 will fall under the action of gravity to the top of pusher 4. By controlling the motor to rotate forward, roller 302 is driven by roller 302, which in turn drives conveyor belt 304. Conveyor belt 304 then drives pusher 4 upward to lift reaction vessel 6. Simultaneously, pusher 4 drives loading assembly 5 upward synchronously.

[0071] like Figure 2 and Figure 3 As shown, after the pusher 4 rises to its maximum height, it enters the loading assembly 5 from the discharge port 103 under the obstruction of the partition 2. Afterwards, the motor is controlled to reverse and drive the roller 302 to rotate. The roller 302 drives the conveyor belt 304 to rotate, and the conveyor belt 304 drives the pusher 4 to move downward. At the same time, the pusher 4 drives the loading assembly 5 to descend synchronously.

[0072] like Figure 4 As shown, after the pusher 4 descends to the lowest height, the loading assembly 5 descends to the lowest height simultaneously and sends the reaction container 6 to the next process.

[0073] Repeat the above steps to achieve continuous transportation of the reaction container 6.

[0074] According to an embodiment of the present invention, on the other hand, a diagnostic device is provided, comprising: the above-mentioned reaction vessel loading device.

[0075] Because the diagnostic equipment includes a reaction vessel loading device, which has the same effect as the reaction vessel loading device, it will not be described in detail here.

[0076] Specifically, the reaction container 6 can be selected according to the needs of the diagnostic equipment. For example, the reaction container 6 is a reaction cup, the open end of the reaction cup is lighter, and the bottom is heavier. During the collision with the protrusion 506, the reaction cup will stand with its lower end facing downward in the loading component 5 due to the influence of gravity, thereby achieving the effect of arranging the reaction cups.

[0077] Diagnostic equipment includes but is not limited to immunoassay analyzers, biochemistry analyzers, and blood gas analyzers.

[0078] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention.
