Description

A food safety testing device Technical Field

[0001] This invention relates to the field of food safety testing technology, and specifically to a food safety testing device. Background Technology

[0002] Food safety testing technology is a crucial means of ensuring food safety. Through quantitative or qualitative analysis, it comprehensively screens for potential harmful substances, environmental pollutants, and pathogenic microorganisms in food, aiming to ensure that every link in the food chain meets quality and safety standards from source to end. However, current food safety testing equipment suffers from some technical deficiencies, becoming a key bottleneck restricting testing efficiency and accuracy. Technical issues

[0003] On the one hand, existing testing equipment uses relatively limited methods, making it difficult to meet the increasingly diverse needs of food safety testing. With the development of the food industry and the continuous emergence of new pollutants, single testing methods are no longer sufficient to meet the multi-dimensional and comprehensive testing requirements for pesticide residues, heavy metal contamination, biotoxins, genetically modified components, and microbial contamination in food. This limitation not only restricts the applicability of testing equipment but also reduces its ability to identify potential risks in complex food matrices.

[0004] On the other hand, the equipment generally lacks integrated sample pretreatment capabilities, and key steps such as centrifugation often require external equipment or manual operation. This deficiency not only leads to uneven mixing of samples and reagents, affecting the full release and purification of target components and thus weakening the accuracy of test results, but also increases the time cost and operational complexity of sample processing, reducing detection efficiency. More importantly, inadequate sample pretreatment may mask the presence of low-concentration contaminants, posing a potential threat to food safety. Technical solutions

[0005] The technical problem to be solved by the present invention is to provide a food safety testing device that can extract samples to be tested, support the simultaneous detection of multiple samples, provide high accuracy of test results, and integrate multiple detection methods.

[0052] The food safety testing equipment of the present invention has the following advantages compared with the prior art:

[0053] (1) The food safety testing equipment of the present invention includes at least a multi-station turntable mechanism, a testing device, and an extraction device. The testing device includes a first testing device and a second testing device. The first testing device is provided with a placement slot for accommodating a row of colloidal gold test cards and a first image acquisition unit adapted to the placement slot for detecting the state of the row of colloidal gold test cards. The second testing device is provided with a second holding part for accommodating colloidal gold test cards and a second image acquisition unit adapted to the second holding part for detecting the state of the colloidal gold test cards. On the one hand, it achieves diversified and efficient detection. The first detection device uses a row of detection cards, allowing for rapid screening of multiple identical or different indicators simultaneously. This is ideal for parallel detection of multiple pollutants (such as multiple pesticide residues) in a batch of samples, greatly improving detection efficiency. The second detection device uses a single colloidal gold detection card, which can be used for precise verification of a single indicator or detection of specific items, improving the flexibility of detection. On the other hand, through the first and second image acquisition units, the color changes of the detection cards can be accurately captured. Quantitative or semi-quantitative analysis is performed through algorithms, avoiding subjective errors and misjudgments caused by human fatigue. This significantly improves the accuracy and reliability of the detection results. Furthermore, the detection results are saved in the form of images and data, facilitating traceability, verification, and database establishment.

[0054] The multi-station turntable mechanism includes a turntable and a first drive mechanism for driving the turntable to rotate. The turntable has at least one first holding part for accommodating a sample container along the circumferential direction. The extraction device includes at least a mounting plate, a liquid aspiration and dissipation device, and a second drive mechanism. The liquid aspiration and dissipation device includes at least a needle tube mounted on the mounting plate and extending at its end in a direction perpendicular to the mounting plate, and a liquid pump connected to the needle tube. The liquid pump is used to aspirate and dissipate liquid through the needle tube. The output end of the second drive mechanism is connected to the mounting plate and is used to drive the mounting plate to move, thereby causing the needle tube to transfer between the first holding part, the placement tank, and the second holding part. The second drive mechanism drives the needle to move, and the liquid pump controls the aspiration and dispensing of liquid, realizing the entire process of drawing sample extract from the sample container (located in the first holding part) and accurately adding it to the detection card (located in the first or second detection device). This reduces the complexity of operation, shortens the processing time of a single sample, and thus improves the overall detection efficiency. At the same time, the machine operation avoids human differences and ensures the consistency of test results between different batches and different operators (good reproducibility).

[0055] (2) The food safety testing equipment of the present invention includes a multi-station turntable mechanism with at least one first weighing device and a vibration device adapted to the first holding section for weighing the sample container. The vibration device includes at least one vibrator adapted to the first holding section, a lifting mechanism connected to the output end of the vibrator for driving the vibrator to fit against the bottom of the sample container in the first holding section, and a mounting frame for mounting the lifting mechanism. On the one hand, the vibration device actively ensures reliable contact between the vibrator and the sample container through the lifting mechanism, and then mixes the sample and extraction reagents strongly and uniformly through high-frequency vibration, ensuring that the reagents and sample matrix are in full contact. The full vibration mixing can destroy the sample structure, causing the target components to be tested (such as pesticide residues and toxins) to dissolve or suspend more quickly and completely in the extract, providing a high-quality test solution for subsequent accurate detection, fundamentally ensuring the accuracy of the test results. On the other hand, the first weighing device enables the sample to be automatically weighed inside the equipment, replacing the cumbersome weighing steps that require manual operation in the past, ensuring the accuracy of the sample quantity and the amount of reagent added, reducing manual operation steps, and reducing human operation errors.

[0056] (3) The food safety testing equipment of the present invention further includes a cover-pushing mechanism corresponding to the vibrator. The cover-pushing mechanism includes at least a base plate, a push plate, and a seventh drive mechanism. The base plate has a transport channel, a first slot communicating with the transport channel, and a second slot adapted to the first holding part at its bottom. One end of the push plate extends into the transport channel and is slidably connected to the base plate. The output end of the seventh drive mechanism is connected to the push plate and is used to drive the push plate to slide relative to the base plate along the extension direction of the transport channel, thereby pushing the container cover located below the first slot to move along the extension direction of the transport channel to below the second slot. On the one hand, by adopting such a structural design, different container covers are provided for different sample containers when continuously processing different batches of samples. Each sample container uses a dedicated container cover when mixing, which physically eliminates cross-contamination caused by the cover contacting residues, ensuring the reliability of the test results. On the other hand, the liquid will not splash out during high-speed vibration, effectively avoiding contamination of the operating table and surrounding samples, thereby ensuring the accuracy of the test results.

[0057] (4) The food safety testing equipment of the present invention further includes a turntable mechanism. The turntable mechanism includes at least a fourth turntable, a ninth driving mechanism for driving the rotation of the first turntable, and a third weighing device. The fourth turntable is provided with at least one fifth holding part for accommodating sample containers along the circumferential direction. The third weighing device is adapted to the fifth holding part and is used to weigh the sample containers located in the fifth holding part. On the one hand, the turntable mechanism is a supplement to the multi-station turntable mechanism. The turntable mechanism is provided with a third weighing device. The multi-station turntable mechanism is responsible for multiple tasks such as "sample mixing, vibration, temporary storage, and waiting for extraction", so that sample weighing can be carried out simultaneously with other pretreatment steps (such as vibration and extraction) on the first turntable, realizing the parallelization of the process and breaking the bottleneck of single turntable sequential processing, thereby greatly improving the overall processing speed and throughput of the equipment. On the other hand, different processing rhythms can be adopted for different batches of samples, or when a certain station needs to be processed for a longer time, it will not affect the operation of other stations. This flexibility allows the equipment to better adapt to "increasingly diversified needs".

[0058] (5) The food safety testing equipment of the present invention is equipped with a reagent adding device, a centrifugation device, and a transport device. The reagent adding device includes a temperature control box for placing reagents, at least one metering pump I corresponding to the temperature control box, a solvent tank, and at least one metering pump II connected to the solvent tank. It accurately adds solvent and reagents to the sample container, ensuring that the amount added each time is highly accurate and consistent, eliminating human operation errors from the source, and providing a key guarantee for the accuracy and reproducibility of the test results. The centrifugation device includes a rotating frame and a tenth driving mechanism for driving the rotating frame to rotate. The rotating frame is provided with at least one sixth holding part for accommodating sample containers at intervals around its rotation center axis, so that the most critical and time-consuming separation and purification steps of the sample can be completed inside the equipment, ensuring that the liquid added to the test card is clear and free of particle interference. This greatly improves the signal-to-noise ratio and accuracy of detection methods such as colloidal gold test cards, effectively prevents false negatives or false positives caused by matrix interference, and enables low-concentration contaminants to be detected more effectively, reducing food safety risks. The transport device includes at least a mechanical gripper three for gripping sample containers and an eleventh drive mechanism. The eleventh drive mechanism is used to drive the mechanical gripper three to transfer between the sixth holding section, the fifth holding section and the first holding section, seamlessly connecting the originally independent modules such as weighing, shaking, centrifugation, reagent addition and detection into a coordinated whole, realizing the flow of samples within the device.

[0096] [Corrected according to Rule 91, 10.02.2026][Deleted] Embodiments of the present invention

[0097] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0098] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element 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 invention.

[0099] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0100] As shown in Figures 1 and 2, a food safety testing device according to this embodiment includes at least a multi-station turntable mechanism 1, a testing device 2, an extraction device 3, a reagent adding device 4, a reaction plate device 5, a turntable mechanism 6, a centrifugation device 7, and a transport device 8.

[0101] As shown in Figure 3, the multi-station turntable mechanism 1 includes a turntable 11 and a first drive mechanism 12 for driving the turntable 11 to rotate. The turntable 1 has at least one first holding part 111 for accommodating sample containers 9 arranged along the circumferential direction. In this embodiment, the turntable 1 has several first holding parts 111 for accommodating sample containers 9 evenly spaced along the circumferential direction to realize the flow of sample containers. On the one hand, it replaces traditional manual operation or reliance on external equipment, significantly improving processing efficiency. On the other hand, it supports the simultaneous detection of multiple samples, further improving detection efficiency.

[0102] The multi-station turntable mechanism 1 is equipped with at least one first weighing device 13 adapted to the first holding section for weighing the sample container. The first weighing device 13 can weigh the sample container to ensure accurate quantification of the sample volume or solvent and avoid volume errors caused by manual measurement (such as pipette operation deviation).

[0103] As shown in Figures 2 and 3, the multi-station turntable mechanism 1 is equipped with a vibration device 14. The vibration device includes at least one vibrator 141 adapted to the first holding section, a lifting mechanism 142 whose output end is connected to the vibrator 1 for driving the vibrator 1 to fit against the bottom of the sample container in the first holding section, and a mounting bracket 143 for mounting the lifting mechanism. The vibrator 141 can apply high-frequency vibration to the sample container 9 in the first holding section 111, so that the sample and solvent are quickly and thoroughly mixed, promoting the dissolution of the target component and avoiding the problem of uneven mixing caused by traditional standing or manual shaking. The position in the multi-station turntable mechanism 1 corresponding to the vibration device 14 is the solvent mixing station of the multi-station turntable mechanism 1.

[0104] On the one hand, the vibration device actively ensures reliable contact between the vibrator and the sample container through a lifting mechanism. Then, it powerfully and uniformly mixes the sample and extraction reagent through high-frequency vibration, ensuring full contact between the reagent and the sample matrix. This thorough vibration mixing can disrupt the sample's structure, allowing the target components (such as pesticide residues and toxins) to dissolve or suspend more quickly and completely in the extract, providing a high-quality test solution for subsequent accurate detection and fundamentally guaranteeing the accuracy of the test results. On the other hand, the first weighing device enables automatic weighing of the sample inside the equipment, replacing the tedious manual weighing steps of the past. This ensures the accuracy of the sample quantity and the amount of reagent added, reduces manual operation steps, and lowers human error.

[0105] As shown in Figure 4, the vibration device 14 also includes a cover-pushing mechanism 144 corresponding to the vibrator. The cover-pushing mechanism includes at least a base plate 1441, a push plate 1442, and a seventh drive mechanism 1443. As shown in Figure 5, the base plate has a transport channel 1444, a first slot 1445 communicating with the transport channel, and a second slot 1446 adapted to the first holding portion at its bottom. One end of the push plate extends into the transport channel and is slidably connected to the base plate. The output end of the seventh drive mechanism is connected to the push plate and is used to drive the push plate to slide relative to the base plate along the extension direction of the transport channel, thereby pushing the container cover located below the first slot to move along the extension direction of the transport channel to below the second slot. On the one hand, this structural design provides different container lids for different sample containers when processing different batches of samples continuously. Each sample container uses a dedicated container lid when mixing, which physically eliminates cross-contamination caused by the lid contacting residues, ensuring the reliability of the test results. On the other hand, the liquid will not splash out during high-speed vibration, effectively avoiding contamination of the operating table and surrounding samples, thereby ensuring the accuracy of the test results.

[0106] In this embodiment, the push-cap mechanism 144 further includes a clamping device 1447 for pressing the container cap located below the second slot 1446 against the opening of the sample container 9. As shown in FIG6, the clamping device 1447 includes a top cover 14471 adapted to the second slot 1446, a pressure plate 14472, and an elastic component 14473 located between the top cover and the pressure plate. The elastic component is used to press the container cap against the opening of the sample container through the top cover. This structural design eliminates the need for cumbersome operations like tightening bottle caps and installing sealing gaskets, as required by traditional sealed devices. After mixing, the overall design of the device enables rapid transfer of the container cap, reducing unnecessary steps. On one hand, the elastic component of the clamping device provides the necessary buffer stroke and clamping force. The generated elastic force continuously acts on the container cap through the top cover, thus pressing the container cap tightly against the sample container opening. It can automatically compensate for minor dimensional tolerances in the manufacturing precision of different containers and container caps, ensuring a consistent and reliable sealing effect regardless of the container used. On the other hand, during high-speed vibration, the sample container will experience slight displacement and vibration. The elastic clamping can dynamically adjust accordingly, always maintaining the clamping force, like an "invisible hand" firmly holding the container cap, avoiding the possibility of cap displacement or seal failure due to rigid clamping, thus improving the accuracy of the test. The "flexible clamping" characteristic also allows the container cap to move in tandem with the vibrator, thereby ensuring thorough mixing of the test sample and the soaking solution inside the sample container.

[0107] As shown in Figure 2, in this embodiment, the multi-station turntable mechanism 1 is further provided with a conduit mounting bracket 15 corresponding to the first weighing device 13. The conduit mounting bracket 15 is used to install a conduit connected to the metering pump 1 of the reagent adding device 4. The reagent adding device 4 adds solvent to the sample container 9 located in the first holding section through the metering pump 2 and the conduit, thereby mixing the sample to be tested with the solvent to form an immersion solution. The position corresponding to the conduit mounting bracket 15 in the multi-station turntable mechanism 1 is the solvent adding station of the multi-station turntable mechanism 1.

[0108] As shown in Figures 1, 2, and 22, the multi-station turntable mechanism 1 also includes a stirring assembly 16 corresponding to the first holding section. The stirring assembly includes a stirrer 161 and a twelfth drive mechanism 162 connected to the stirrer at its output end. The twelfth drive mechanism drives the stirrer 161 to extend into the sample container located in the first holding section to stir and break up the sample to be tested. In this embodiment, the position corresponding to the stirring assembly in the first holding section of the multi-station turntable mechanism 1 is the stirring station.

[0109] The detection device 2, as shown in Figures 1 and 2, includes a first detection device 21 and a second detection device 22. The first detection device 21 is provided with a placement slot 211 for accommodating a row of colloidal gold test cards 103, and a first image acquisition unit 212 adapted to the placement slot for detecting the state of the row of colloidal gold test cards. The second detection device 22 is provided with a second holding part 221 for accommodating colloidal gold test cards 102, and a second image acquisition unit 222 adapted to the second holding part for detecting the state of the colloidal gold test cards. On the one hand, it achieves diversified and efficient detection. The first detection device uses a row of detection cards, allowing for rapid screening of multiple identical or different indicators simultaneously. This is ideal for parallel detection of multiple pollutants (such as multiple pesticide residues) in a batch of samples, greatly improving detection efficiency. The second detection device uses a single colloidal gold detection card, which can be used for precise verification of a single indicator or detection of specific items, improving the flexibility of detection. On the other hand, through the first and second image acquisition units, the color changes of the detection cards can be accurately captured. Quantitative or semi-quantitative analysis is performed through algorithms, avoiding subjective errors and misjudgments caused by human fatigue. This significantly improves the accuracy and reliability of the detection results. Furthermore, the detection results are saved in the form of images and data, facilitating traceability, verification, and database establishment.

[0110] The first detection device, as shown in Figures 7 and 8, further includes:

[0111] Storage chamber 213, the bottom of which is provided with a discharge port 2131 for receiving the sequential drop of a row of colloidal gold test cards;

[0112] Mounting plate 214 is fixedly connected to the bottom of the storage compartment and is provided with a sliding groove 2141;

[0113] The sliding plate 215 is adapted to the chute and has a closed state that closes the discharge port of the storage chamber and an open state that opens the discharge port of the storage chamber.

[0114] The third drive mechanism 216 has its output end connected to the sliding plate and is used to drive the sliding plate to slide relative to the slide groove, thereby enabling the sliding plate to switch between a closed state and an open state.

[0115] The placement slot 211 is located at one end of the mounting plate 214 and is connected to the slide groove. The sliding plate switches from an open state to a closed state, pushing the row of colloidal gold test cards to slide relative to the slide groove, thereby placing the row of colloidal gold test cards in the placement slot.

[0116] The second detection device 22, as shown in Figures 9, 10, and 11, further includes:

[0117] Turntable 223, with at least one storage box 2231 for holding colloidal gold test cards along the circumferential direction, and discharge port 2232 corresponding to storage box 1 for holding colloidal gold test cards falling in sequence.

[0118] Mounting plate 3 224, which is located below turntable 2, and has a groove 2241 on the side near turntable 2 that matches the discharge port 2;

[0119] The fourth drive mechanism 225 is used to drive the rotation of the turntable two relative to the mounting plate three.

[0120] The two sides of the discharge port 2232 are provided with a retaining portion 2233 extending towards the bottom wall of the groove 2241. As shown in Figure 12, the retaining portion and the bottom wall of the groove form a discharge channel 2234 for accommodating the colloidal gold test card. The groove 2241 is provided with a discharge port 2242 that matches the discharge channel.

[0121] As shown in Figure 9, the second detection device 22 also includes:

[0122] Turntable 3 226, the second holding part 221 is arranged at intervals along the circumference of turntable 3;

[0123] Mounting plate 4 227, Mounting plate 4 is located below turntable 3;

[0124] The fifth drive mechanism 228 has its output end connected to the turntable three and is used to drive the turntable three to rotate relative to the mounting plate four.

[0125] The device includes a mechanical gripper 229 adapted to the discharge port 3, and a thirteenth drive mechanism 2210. The mechanical gripper 229 has a material-grabbing state in which it extends into the discharge port 3 to grab the colloidal gold test card, and a material-discharging state in which it extends out of the discharge port 3 and is positioned above the second holding part to place the colloidal gold test card. The thirteenth drive mechanism is used to drive the mechanical gripper 229 to switch between the material-grabbing state and the material-discharging state.

[0126] It should be noted that in this embodiment, the first image acquisition unit 212 and the second image acquisition unit 222 adopt the same structural configuration, both having a camera for acquiring images and LED beads that match the camera.

[0127] The extraction device 3, as shown in Figures 1, 2, and 13, includes at least a mounting plate 31, a liquid aspiration and dissipation device 32, and a second drive mechanism 33. The liquid aspiration and dissipation device includes at least a needle tube 321 mounted on the mounting plate with its end extending perpendicular to the mounting plate, and a liquid pump 322 connected to the needle tube. The liquid pump 322 is used for aspiration and dissipation of liquid through the needle tube. The output end of the second drive mechanism is connected to the mounting plate 31 and is used to drive the mounting plate 31 to move, thereby transferring the needle tube between the first holding section, the placement tank, and the second holding section. The second drive mechanism drives the needle tube to move, and the liquid pump 322 controls the aspiration and dissipation of liquid, realizing the entire process of aspirating sample extract from the sample container (located in the first holding section) and accurately adding it to the detection card (located in the first or second detection device). This reduces operational complexity, shortens the processing time for a single sample, and thus improves overall detection efficiency. Simultaneously, machine operation avoids human error and ensures consistency (good reproducibility) of test results between different batches and different operators.

[0128] The extraction device 3 also includes a cleaning device 34. The cleaning device includes at least a cleaning tank 341 for cleaning the syringe 321 and a second liquid pump 342 connected to the syringe, the second liquid pump adding cleaning fluid into the cleaning tank through the syringe.

[0129] The cleaning tank 341 has an overflow pipe 3411 on its side wall and a solenoid valve 3412 installed at its bottom. The solenoid valve is used to drain the cleaning solution from the cleaning tank after the syringe is cleaned. The cleaning principle of the extraction device 3 in this embodiment is as follows:

[0130] After the extraction device 3 completes liquid extraction, the syringe 321 needs to be cleaned. First, the second drive mechanism 33 drives the syringe 321 into the cleaning tank 341. Liquid pump 1 322 stops working, and liquid pump 2 342 adds cleaning solution into the cleaning tank through the syringe 321 to rinse the inside of the syringe. The cleaning solution in the cleaning tank 341 cleans the outside of the syringe 321. After cleaning, the liquid is discharged through the solenoid valve 3412 installed at the bottom of the cleaning tank 341. After each pipetting operation, the second drive mechanism 33 drives the syringe 321 into the cleaning tank 341 for rinsing to thoroughly remove residual samples or reagents and eliminate the risk of cross-contamination between different samples.

[0131] The reaction disk device 5, as shown in Figures 1, 2, and 14, includes at least the following components:

[0132] The reaction plate 51 is provided with at least one third holding part 511 for accommodating the gold microporous detection box and at least one fourth holding part 512 for accommodating the reaction cup 101 along the circumferential direction.

[0133] Mounting plate 52, which is located below the reaction plate;

[0134] The sixth drive mechanism 53 has its output end connected to the reaction disk and is used to drive the reaction disk to rotate relative to the mounting plate 5.

[0135] The second drive mechanism is also used to drive the mounting plate to move, thereby causing the needle to transfer between the first holding part, the placement slot, the second holding part, the third holding part, and the fourth holding part.

[0136] As shown in Figure 15, the mounting plate 52 is equipped with a second weighing device 521 adapted to the fourth holding section for weighing the reaction cup 101, and a vibrator 522 adapted to the fourth holding section for vibrating the reaction cup. In this embodiment, the fourth holding section of the reaction plate device 5 and the vibrator 522 correspond to the reagent mixing station.

[0137] The reaction plate device 5, as shown in Figure 14, also includes a hot air device 54 for concentrating the liquid in the reaction cup located in the fourth holding section.

[0138] The hot air device includes at least one hot air gun 541 with an air outlet adapted to the fourth holding part, a second mounting bracket 542 for mounting the hot air gun, a second mechanical gripper 543 located below the hot air gun for gripping the reaction cup, and an eighth drive mechanism 544.

[0139] The output end of the eighth drive mechanism is connected to the second mechanical gripper, which is used to drive the second mechanical gripper to transport the reaction cup to the hot air gun outlet.

[0140] In this embodiment, the fourth holding part of the reaction plate device 5 corresponds to the hot air device 54 as a hot air station.

[0141] The reagent adding device 4, as shown in Figures 1, 2 and 16, includes a temperature control box 41 for holding reagents, at least one metering pump 42 corresponding to the temperature control box, a solvent tank 43, and at least one metering pump 44 connected to the solvent tank.

[0142] The reagent addition device uses metering pump one to transport the reagent in the temperature control chamber to the reaction cup in the fourth holding section, and uses metering pump two to transport the solvent in the solvent tank to the sample container in the first holding section. It precisely adds solvent and reagent to the sample container, ensuring that the amount added each time is highly accurate and consistent, eliminating human operation error from the source, and providing a key guarantee for the accuracy and reproducibility of the test results.

[0143] In this embodiment, the fourth holding part of the reaction plate device 5 corresponds to the output end of the metering pump 42 as the reagent adding station, and the bottom of the reagent adding station is the second weighing device 521. With this structural design, the data collected by the second weighing device during the process of adding reagents to the reaction cup located in the fourth holding part by the metering pump 42 can ensure the accuracy of the amount of reagent added.

[0144] As shown in Figures 1, 2, and 17, the turntable mechanism 6 includes at least a fourth turntable 61, a ninth drive mechanism 62 for driving the rotation of the fourth turntable, and a third weighing device 63. The fourth turntable has at least one fifth holding section 611 for accommodating sample containers along its circumference. The third weighing device is adapted to the fifth holding section and is used to weigh the sample containers located in the fifth holding section. On the one hand, the turntable mechanism complements the multi-station turntable mechanism. The turntable mechanism is equipped with the third weighing device. The multi-station turntable mechanism is responsible for multiple tasks such as "sample mixing, vibration, temporary storage, and waiting for extraction," allowing sample weighing to be performed simultaneously with other pretreatment steps (such as vibration and extraction) on the first turntable. This achieves parallel processing, breaks the bottleneck of single-turntable sequential processing, and greatly improves the overall processing speed and throughput of the equipment. On the other hand, different processing rhythms can be adopted for different batches of samples, or when a certain station requires longer processing time, it will not affect the operation of other stations. This flexibility allows the equipment to better adapt to "increasingly diversified needs."

[0145] As shown in Figures 1, 2, and 18, the centrifuge device 7 includes a rotating frame 71 and a tenth drive mechanism 72 for driving the rotating frame's rotation. The rotating frame has at least one sixth holding section 711 spaced around its central axis for accommodating sample containers. This allows the sample to complete the most critical and time-consuming separation and purification steps inside the device, ensuring that the liquid added to the detection card is clear and free of particulate interference. This significantly improves the signal-to-noise ratio and accuracy of detection methods such as colloidal gold detection cards, effectively preventing false negatives or false positives caused by matrix interference. It also enables the more effective detection of low-concentration contaminants, reducing food safety risks.

[0146] In this embodiment, as shown in Figures 1, 2, 19, and 20, a water bath heating module 10 is also included. The water bath heating module includes at least a water bath 1001, which is equipped with a water inlet pipe 1002 for adding liquid into the water bath. Inside the water bath, a water level sensor 1003 for collecting water level data and a temperature sensor 1004 for collecting liquid temperature data are installed. A heating unit 1005 is installed at the bottom of the water bath for heating the liquid in the water bath based on the liquid temperature data collected by the temperature sensor 1004.

[0147] As shown in Figures 1, 2 and 21, the transport device 8 includes at least a mechanical gripper 81 for gripping sample containers and an eleventh drive mechanism 82. The eleventh drive mechanism is used to drive the mechanical gripper 81 to transfer between the sixth holding section, the fifth holding section, the first holding section and the water bath, seamlessly connecting the originally independent modules such as weighing, shaking, centrifugation, reagent addition and detection into a coordinated whole, realizing the flow of samples within the device.
