Description

Technical Field

[0001] This utility model relates to the field of automated in vitro diagnostic equipment technology, specifically to a reaction vessel feeding device and diagnostic equipment. Background Technology

[0002] In the use of automated in vitro diagnostic equipment, reaction containers are needed to carry samples and reagents. These reaction containers are generally automatically fed by a feeding device.

[0003] Currently, feeding devices typically use chain-driven mechanisms to feed reaction vessels. However, due to the inherent characteristics of chain drives, these mechanisms occupy a large amount of space and are prone to jamming of the reaction vessel, resulting in poor reliability of the feeding device. Utility Model Content

[0004] In view of this, the present invention provides a reaction vessel feeding device and diagnostic equipment to solve the problems of large space occupation and poor reliability of the feeding device using a chain-type transmission mechanism.

[0005] In a first aspect, this utility model provides a reaction vessel feeding device, comprising:

[0006] The hopper has a feed inlet at the top and an opening at the bottom.

[0007] A partition is fixedly installed inside the hopper to divide the opening into a first sub-opening and a second sub-opening;

[0008] The drive assembly is located at the lower end of the hopper;

[0009] The pusher and the feeding assembly are respectively connected to the drive assembly and located on opposite sides of the partition. The drive assembly drives the pusher to move up and down and pass through the first sub-opening to lift the reaction vessel. At the same time, the drive assembly drives the feeding assembly to move up and down and pass through the second sub-opening to receive the reaction vessel lifted by the pusher.

[0010] Beneficial Effects: This invention's reaction vessel feeding device uses a hopper to support multiple reaction vessels. A drive assembly drives a pusher to move upwards through a first sub-opening, lifting the reaction vessel to the feeding assembly. Under the obstruction of a partition, the reaction vessel falls to the feeding assembly. Simultaneously, the drive assembly drives the feeding assembly upwards through a second sub-opening to receive the reaction vessel. Then, the drive assembly drives the feeding assembly downwards, carrying the reaction vessel to the next process. By simultaneously driving the pusher and feeding assembly to move up and down synchronously, continuous conveying of reaction vessels is achieved. This simplifies the overall structure of the reaction vessel feeding device, reduces space requirements, and ensures high reliability due to the continuous up-and-down movement method.

[0011] In one optional implementation, the driving component includes:

[0012] The support is fixedly installed at the bottom of the hopper, and a roller is provided at the upper and lower ends of one side.

[0013] A driving component is fixedly mounted on the support, and the driving shaft of the driving component is connected to one of the rollers;

[0014] A conveyor belt is fitted between the two rollers and connected to the pusher.

[0015] Beneficial effects: The support is used to support the drive unit and the conveyor belt. The drive unit drives the rollers to rotate, which in turn drives the conveyor belt to rotate. The conveyor belt then drives the pusher to move up and down, continuously lifting multiple reaction vessels and sending them to the feeding assembly. The drive assembly uses a conveyor belt instead of the traditional conveyor chain structure, which occupies less space, has lower cost, and is more reliable.

[0016] In one alternative embodiment, the pusher is provided with a clamping part for clamping the conveyor belt.

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

[0018] In one optional embodiment, the end face of the support where the roller is located is also provided with a guide rail extending in the vertical direction, and the pusher is provided with a slider that is slidably connected to the guide rail.

[0019] Beneficial effects: The pusher component is slidably connected to the guide rail on the support via a slider, which can further improve the reliability of the drive component and prevent the reaction vessel from jamming.

[0020] In one optional implementation, the feeding assembly includes:

[0021] A pair of guide bars are disposed opposite each other between the inner wall of the hopper and the partition;

[0022] The slide bar is fixedly connected to the pusher via a connecting plate and is positioned between a pair of guide bars, allowing it to move up and down along the pair of guide bars.

[0023] A pair of baffles are disposed opposite to the slide bar, and together with the slide bar and a guide bar opposite to the slide bar, they form a receiving space for accommodating the reaction vessel.

[0024] Beneficial effects: After the reaction vessel is lifted, it enters the receiving space enclosed by a pair of baffles, a sliding bar, and a guide bar, blocked by the partition. Since the sliding bar is fixedly connected to the pusher via a connecting plate, the sliding bar and the pair of baffles also rise to their maximum height under the drive assembly. Then, driven by the drive assembly, it moves downwards, and after descending to its lowest point, the reaction vessel is delivered. During the downward movement of the sliding bar and the pair of baffles by the drive assembly, the reaction vessel, under the influence of gravity, flips and aligns within the receiving space, and after descending to its lowest point, flows to the next process.

[0025] In one alternative embodiment, a pair of guide bars extend from the second sub-opening to the lower end of the hopper, and the feeding assembly further includes an extension plate disposed at the lower end of the hopper, the extension plate being spaced apart from the partition and fixedly connected to the pair of guide bars.

[0026] Beneficial effect: By setting up an extension plate and a pair of extended guide bars, the reaction vessel that moves up and down can be protected.

[0027] In one alternative embodiment, the inner wall of the guide bar opposite to the slider is provided with a plurality of protrusions at intervals.

[0028] Beneficial effects: During the descent of the reaction vessel, it automatically flips and corrects itself by colliding with the protrusions on the inner wall of the guide bar, thereby aligning the reaction vessels and preventing them from jamming.

[0029] In one alternative embodiment, the top of the guide bar opposite to the slider is provided with a downwardly inclined sub-guide bar.

[0030] Beneficial effect: By setting sub-guide bars, the reaction vessel can be guided downward into the feeding assembly.

[0031] In one alternative embodiment, the top of the partition is lower than the feed inlet, and the top of the partition and the side wall opposite to the hopper form a discharge outlet. The pusher, driven by the drive assembly, pushes the reaction vessel up to at least the height of the discharge outlet.

[0032] Beneficial effect: The top of the baffle is lower than the feed inlet to prevent the reaction vessel from detaching from the feed inlet and the drive component drives the pusher to lift the reaction vessel to the maximum position, and then it enters the feeding component from the discharge outlet.

[0033] Secondly, this utility model also provides a diagnostic device, including: the above-mentioned reaction vessel feeding device.

[0034] Beneficial effects: Since the diagnostic equipment includes a reaction vessel loading device, it has the same effect as the reaction vessel loading device, so it will not be described in detail here. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0047] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, a reaction vessel feeding device is provided, mainly comprising: a hopper 1, a partition 2, a driving assembly 3, a pusher 4, and a feeding assembly 5. The hopper 1 has a feed inlet 101 at the top and an opening 102 at the bottom. The partition 2 is fixedly disposed within the hopper 1, dividing the opening 102 into a first sub-opening 1021 and a second sub-opening 1022. The driving assembly 3 is disposed at the lower end of the hopper 1. The pusher 4 and the feeding assembly 5 are respectively connected to the driving assembly 3 and located on opposite sides of the partition 2. The driving 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. Simultaneously, the driving assembly 3 drives the feeding 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 feeding device provided in this embodiment of the invention carries multiple reaction vessels 6 via a hopper 1. A drive assembly 3 drives a pusher 4 to move upwards through a first sub-opening 1021, lifting the reaction vessel 6 to a feeding assembly 5. Blocked by a partition 2, the reaction vessel 6 falls to the feeding assembly 5. Simultaneously, the drive assembly 3 drives the feeding assembly 5 to move upwards through a second sub-opening 1022 to receive the reaction vessel 6. Then, the drive assembly 3 drives the feeding assembly 5 to descend, bringing the reaction vessel 6 to the next process. By simultaneously driving the pusher 4 and the feeding assembly 5 to move up and down synchronously, the drive assembly 3 achieves continuous conveying of the reaction vessel 6, simplifying the overall structure of the reaction vessel feeding device, reducing space occupation, and employing a continuous up-and-down movement method for conveying the reaction vessel 6, thus ensuring high reliability.

[0050] Specifically, such as Figure 1 and Figure 6As shown, the hopper 1 is funnel-shaped, with a large opening at the top serving as the feed inlet 101 and a small opening at the bottom serving as the opening 102. The partition 2 is fixed inside the hopper 1 by fasteners. The reaction vessels 6 accumulate at the bottom of the hopper 1 under gravity and are continuously pushed upwards by the pusher 4. Blocked by the partition 2, they enter the feeding assembly 5. The pusher 4 can be a pusher plate, with a rolling roller on its top. The roller directly contacts the reaction vessel 6 to protect it.

[0051] It should be noted that the pusher 4 and the feeding assembly 5 in this 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 feeding 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 feeding assembly 5 to move up and down through the pusher 4, thus realizing the indirect connection between the feeding assembly 5 and the drive assembly 3.

[0052] Furthermore, this embodiment of the invention does not limit the structure of the drive component 3, and any existing structure can be selected as needed.

[0053] In one embodiment, such as Figures 2 to 5 As shown, the drive assembly 3 mainly includes: a support 301, a drive component 303, and a conveyor belt 304. The support 301 is fixedly mounted on the bottom of the hopper 1, and a roller 302 is provided at each of the upper and lower ends of one side. The drive component 303 is fixedly mounted on the support 301, and the drive shaft of the drive component 303 is connected to one of the rollers 302. The conveyor belt 304 is sleeved between the two rollers 302 and connected to the pusher component 4. The drive component 303 can be a motor.

[0054] The support 301 in this embodiment supports the drive component 303 and the conveyor belt 304. The drive component 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, so as to continuously lift multiple reaction vessels 6 and send them into the feeding assembly 5. The drive assembly 3 uses a conveyor belt 304 instead of the traditional conveyor chain structure, which occupies less space, has lower cost, and higher reliability.

[0055] In addition, compared with the traditional conveyor chain structure, this utility model embodiment also separates the pusher 4 and the feeding component 5, and uses the same drive component 303 to drive the two to move up and down synchronously, which simplifies the overall structure, occupies less space, reduces manufacturing costs, and enhances reliability.

[0056] It should be noted that this embodiment of the invention does not limit the fixed connection method between the support 301 and the hopper 1. A snap-fit ​​structure can be used for quick installation and disassembly, or a fastener-type structure can be used to improve tightness. For example, a support plate is fixedly mounted on the top of the support 301 using fasteners, and the support plate is fitted onto the bottom of the hopper 1 and fixedly connected to the hopper 1 using fasteners. Conventional fasteners such as screws and bolts can be used.

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

[0058] It should be noted that the structure of the clamping part 401 is not limited in this embodiment of the invention, as long as the clamping part 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 extends to form a pair of clamping plates on the side near the conveyor belt, and the pair of clamping plates clamp onto 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, such as Figure 7 As shown, the support 301 has a roller 302 on its end face and a guide rail 305 extending in the vertical direction. 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 through the slider 402, which can further improve the reliability of the drive assembly 3 and prevent the reaction vessel 6 from jamming.

[0060] Since the feeding component 5 also needs to transport the reaction vessel 6 to the next process, in order to reduce the space occupied by the drive component 3 in the downstream mechanism of the feeding component 5, the feeding component 5 of this utility model embodiment is fixedly connected to the pusher 4, and the pusher 4 is directly fixed to the conveyor belt 304.

[0061] In one embodiment, such as Figure 8As shown, the feeding assembly 5 mainly includes: a pair of guide bars 501, a sliding bar 502, and a pair of baffles 504. The pair of guide bars 501 are disposed opposite each other between the inner wall of the hopper 1 and the partition 2. The sliding bar 502 is fixedly connected to the pusher 4 through a connecting plate 503 and is disposed 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 disposed opposite each other on the sliding bar 502, and together with the sliding bar 502 and one of the guide bars 501 opposite to the sliding bar 502, they form a receiving space for accommodating the reaction vessel 6. The pair of guide bars 501, the inner wall of the hopper 1, and the partition 2 form a channel for the sliding bar 502 and the pair of baffles 504 to slide up and down.

[0062] After the reaction vessel 6 of this embodiment is lifted, it enters the receiving space formed by a pair of baffles 504, a slide bar 502, and a guide bar 501 under the obstruction of the partition 2. Since the slide bar 502 is fixedly connected to the pusher 4 through the connecting plate 503, the slide bar 502 and the pair of baffles 504 also rise to their maximum height under the drive of the drive assembly 3. Then, under the drive of the drive assembly 3, it moves downward and, after descending to the lowest point, sends the reaction vessel 6 out. During the downward movement of the slide bar 502 and the pair of baffles 504 driven by the drive assembly 3, the reaction vessel 6 is affected by gravity and flips and aligns within the receiving space, and after descending to the lowest point, it flows to the next process.

[0063] Furthermore, in one embodiment, such as 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 feeding assembly 5 also 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 setting the extension plate 505 to cooperate with the extended pair of guide bars 501, the vertically moving reaction vessel 6 can be protected.

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

[0065] Furthermore, in one embodiment, such as Figure 8 As shown, the inner wall of the guide bar 501, which is opposite to the slider 502, is provided with multiple protrusions 506 at intervals. During the descent of the reaction vessel 6, it automatically flips and corrects itself by colliding with the protrusions 506 on the inner wall of the guide bar 501, thereby aligning the reaction vessel 6 and preventing it from jamming.

[0066] It should be noted that the shape of the protrusion 506 is not limited in this embodiment of the utility model. For example, the protrusion 506 can be arc-shaped, spherical, cylindrical, etc.

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

[0068] In one embodiment, such as Figure 1 As 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 to the hopper 1 form the discharge outlet 103. Under the drive of the drive assembly 3, the pusher 4 pushes the reaction vessel 6 to at least the height of the discharge outlet 103. The top of the partition 2 is lower than the feed inlet 101 to prevent the reaction vessel 6 from detaching from the feed inlet 101 and the drive assembly 3 drives the pusher 4 to lift the reaction vessel 6 to its maximum position, after which it enters the feeding assembly 5 from the discharge outlet 103.

[0069] The working principle of this utility model embodiment is as follows:

[0070] like Figure 1 As shown, reaction vessel 6 is placed inside hopper 1, and at least one reaction vessel 6 will fall above pusher 4 under gravity. By controlling the motor to rotate forward, roller 302 is driven to rotate, which in turn drives conveyor belt 304 to rotate. Conveyor belt 304 then drives pusher 4 to move upward, thus lifting reaction vessel 6. At the same time, pusher 4 drives feeding assembly 5 to rise synchronously.

[0071] like Figure 2 and Figure 3 As shown, after the pusher 4 rises to its maximum height, it enters the feeding assembly 5 through the discharge port 103 under the obstruction of the partition 2. Then, the control motor reverses to drive the roller 302 to rotate, the roller 302 drives the conveyor belt 304 to rotate, the conveyor belt 304 then drives the pusher 4 to move downward, and at the same time, the pusher 4 drives the feeding assembly 5 to descend synchronously.

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

[0073] Repeat the above steps to achieve continuous delivery of reaction vessel 6.

[0074] According to an embodiment of the present invention, another aspect provides a diagnostic device, including the above-described reaction vessel feeding device.

[0075] Since 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 opening end of the reaction cup is lighter and the bottom is heavier. During the collision with the protrusion 506, the reaction cup will stand upright in the feeding component 5 with the bottom end facing down due to gravity, thus achieving the effect of organizing the reaction cup.

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

[0078] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
