Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of testing or analyzing materials by means of determining the chemical or physical properties of materials, and particularly relates to a full-automatic fast detection equipment for multiple types of target objects in food. BACKGROUND

[0002] Food safety refers to the fact that food is non-toxic and harmless, meets the nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. As a key link of food safety supervision, it is crucial to do food safety detection well. Such food safety detection includes detecting dangerous target objects in food or feed.

[0003] With the increasing requirements of consumers for food quality and safety, it is particularly important to quickly and accurately detect harmful target substances that may exist in food. When food safety quality is detected, fast detection technology is often used, which can shorten the detection period while meeting the detection requirements of relevant indicators, and can also reduce the capital investment to a certain extent, thereby improving the economic benefits of enterprises. At present, the fast detection technologies commonly used in the field of food safety mainly include time-resolved fluorescence immunoassay and colloidal gold immunochromatography, and the basic principle is to fix specific antibodies or antigens on a certain zone of a nitrocellulose membrane (NC membrane) in advance. After the sample is added to one end of the dry nitrocellulose membrane, the sample will move forward along the membrane due to capillary action. In the moving process, the corresponding antigen or antibody in the sample (depending on whether the antibody or the antigen is fixed) will specifically bind to the fixed antibody or antigen on the membrane. Finally, the signal values of the quality control line and the detection line are read by using the corresponding detection instrument, and the concentration of the target object in the sample is calculated according to the corresponding standard curve. This technology requires correct analysis of the measurement target in a short time.

[0004] The food safety testing methods currently used in the market generally have problems such as being fully manual, having many steps, and requiring a large amount of manpower. Specifically, the fully manual testing process includes multiple steps such as sample collection, pretreatment, and instrument analysis. Each step requires professional personnel to perform delicate operations. Among them, sample pretreatment, as a key step in the testing process, often involves tedious steps and requires certain operating skills. Not only is the operation efficiency low, but it is also easy to introduce more errors, thereby affecting the accuracy of the test results. The errors caused by this manual testing will even run through the entire testing process. Furthermore, manual testing methods often require frequent changes in instrument models and supporting test kits when testing multiple indicators, such as mycotoxins, pesticide residues, genetically modified substances, heavy metals, etc., and the sample pretreatment and dilution methods for each indicator are different, which further increases the difficulty, complexity, and cost of the testing process. At the same time, in actual operation, some indicators' extracts contain components such as methanol, acid, and alkali. The manual testing work scene is more likely to cause personal injury and environmental pollution.

[0005] Therefore, there is an urgent need for a device that can effectively take into account sample pre-processing and integrate multi-index detection. Utility Model Content

During the implementation process, the transfer seat 30 is provided with a structure having a side baffle to ensure that it can be returned to the right position during the transfer of the detection card 2 to avoid tilting or falling. In order to meet the detection requirements, For the loading and unloading of the card 2, the transfer seat 30 is generally also provided with left and right halves, and an opening for the first lever 32 to pass through is provided at the bottom, which is consistent with the opening 40 of the card slot 4; then the transfer seat 30 is driven by the fifth X-axis moving mechanism 34 to the preset incubation station 31, which is generally a plurality of incubation stations 31 arranged in parallel, and incubation begins; it should be noted that the incubation of the incubation station 31 is generally completed by a temperature control device, which is easily understood by those skilled in the art. The temperature control device can automatically increase the temperature under the control of the control unit and strictly control the temperature within the preset temperature ±0.5°C;

[0087] After the incubation is completed, the second lever 35 set at the other section of the incubation station 31 relative to the transfer seat 30 is operated, and the sixth X-axis moving mechanism and the third Y-axis moving mechanism 36 cooperate to drive the second lever 35 to perform X-axis positioning and Y-axis pushing action, and push the incubated test card 2 into the waiting transfer seat 30, and then the transfer seat 30 is driven by the fifth X-axis moving mechanism 34 to the detection station at the detection unit 39.

[0088] The detection unit 39 includes a fluorescence detection mechanism and / or a colloidal gold detection mechanism that is arranged in conjunction with the transfer seat 30 .

[0089] In the present invention, during the specific implementation process, the detection unit 39 detects the incubated detection card 2 with a fluorescence detection mechanism and / or a colloidal gold detection mechanism. The fluorescence detection / colloidal gold detection here is a disclosed technical content, and those skilled in the art can set the structure of the fluorescence detection mechanism and / or colloidal gold detection mechanism according to their needs.

[0090] In conjunction with the transfer base 30 , the second Y-axis moving mechanism 33 and the fifth X-axis moving mechanism 34 , a detection card 2 exit station is also provided.

[0091] In the present invention, after the inspection is completed, it is necessary to make the inspection card 2 exit the inspection unit 39 as soon as possible to avoid affecting the inspection work of the next inspection card 2. Therefore, the second Y-axis moving mechanism 33 and the fifth X-axis moving mechanism 34 cooperate with the first shifting rod 32 to act on the transfer seat 30 to push the inspection card 2 out to the exit position; in the embodiment, the exit position is located on the other side of the transfer seat 30 relative to the card slot 4, that is, at this time the first shifting rod 32 can rotate in one direction. Under this setting, the inspection card 2 can only move on one side relative to the transfer seat 30. This is a structure that can be easily understood by those skilled in the art. For example, a stopper 44 is used to block the side of the first shifting rod 32 facing the exit position, so that the first shifting rod 32 does not rotate relative to the mounting slot 43 when pushing the inspection card 2 into the transfer seat 30 and pushing the inspection card 2 out from the transfer seat 30, and the first shifting rod 32 rotates when moving in the reverse direction to avoid the inspection card 2;

[0092] The exit station here is also set as an inclined slide 42 on one side that is the same height as or slightly lower than the transfer seat 30. The detection card 2 can use the inclined slide 42 to slide out of the shell 51 to the waste collection area (not shown in the figure). The position of the inclined slide 42 can be optimized and adjusted based on the actual structure inside the equipment.

[0093] In the present invention, a full-process tracking device is provided in conjunction with the whole machine, including but not limited to in-place sensors, cameras, etc., which cooperate with the control unit to facilitate real-time acquisition of the actual working status of the whole machine and facilitate backtracking. At the same time, the whole machine is arranged according to modules, and each module is equipped with a self-test function. The self-test signal is obtained at a preset frequency and summarized to the control unit. If there is an abnormality in the self-test of any module, an error will be reported and the machine will enter the maintenance state until the fault is eliminated.

[0094] Furthermore, in the present invention, the device can be connected to the Internet and upload data to the cloud, while checking the usage in various places and configuring the printing function based on demand; the device also has self-sleep and scheduled power-on functions. When it is in self-sleep and has not worked for more than the preset time, it will automatically complete the shutdown operation. The scheduled power-on is particularly suitable for environments with low temperatures. The incubation module can be heated in advance through scheduled power-on to ensure work efficiency.

[0095] The above functions are easily understood by those skilled in the art, and those skilled in the art can configure them according to their needs.

[0096] The detection method of the equipment of the utility model comprises the following steps:

[0100] S4 Any sample to be detected completes liquid addition and stirring according to a working tempo until supernatant is obtained; the sample to be detected is moved to the sample processing unit;

[0101] S5 According to a working tempo, the sample processing unit obtains the supernatant and mixes the supernatant uniformly with a dilution liquid and / or a detection liquid, and then adds the supernatant to one or more detection cards 2 controlled by the detection card 2 control unit to complete sampling; after sampling, the sample processing unit pushes out the sample to be detected;

[0102] S6 The detection card 2 control unit pushes out the detection cards 2 after incubation one by one to the detection unit 39 for detection, and the detection cards 2 after detection are exited;

[0103] S7 All the detection cards 2 are detected, and detection results are obtained.
