Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically relating to a colloidal gold rapid test card scanning device. Background Technology

[0002] Colloidal gold rapid test strips are rapid detection tools based on colloidal gold labeling technology and immunochromatography. They work by reacting the sample with specific antibodies on the test strip, resulting in a visible color change, thus indicating the presence or absence of a target substance in the sample. However, traditional manual interpretation methods suffer from high subjectivity, low accuracy, and difficulty in quantification, limiting their application in high-precision detection. Therefore, devices for automatically scanning colloidal gold rapid test strip results have emerged, but existing devices have certain shortcomings, such as those described in publication number "CN 210037850". A Chinese patent for "U" discloses a colloidal gold rapid test card scanning device, including a machine base, a first conveyor belt mounted on the machine base for transporting colloidal gold rapid test cards, a second conveyor belt mounted on the machine base for transporting sample cups, a dispensing mechanism for extracting sample solution from the sample cups and dispensing it into the colloidal gold rapid test card, and a CCD camera mounted above the first conveyor belt for acquiring images of the colloidal gold rapid test card; the first and second conveyor belts are arranged parallel to each other and have the same conveying speed; the first conveyor belt has a plurality of first positioning grooves evenly arranged along its length for positioning the colloidal gold rapid test card, and the second conveyor belt has a plurality of first positioning grooves evenly arranged along its length. Multiple second positioning slots for positioning sample cups are evenly arranged, with the first and second positioning slots facing each other. During testing, the device is equipped with an automatic liquid dispensing mechanism to the colloidal gold rapid test card for detection, and a conveying mechanism to move the colloidal gold rapid test card and sample cups. Although the device can detect automatically, it requires reciprocating movement through a single dispensing mechanism during detection. Therefore, during detection, it is necessary to wait for a complete detection before the device can continue to move the sample cup and colloidal gold rapid test card to another sample cup for sampling. As a result, the preparation time is long and the detection efficiency is low. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 As shown, this utility model provides the following technical solution:

[0029] A colloidal gold rapid test card scanning device includes a support member 1. A second conveying member 2 and a first conveying member 3 are symmetrically installed on the top of the support member 1. The second conveying member 2 and the first conveying member 3 respectively form a conveying channel for conveying a sample cup and a colloidal gold rapid test card along a preset path.

[0030] Furthermore, a scanning component 4 is installed on the top of the support component 1. The scanning component 4 is located between the second conveyor component 2 and the first conveyor component 3. The scanning component 4 includes a scanning part for scanning the colloidal gold rapid test card and a dripping part for drawing the sample from the sample cup and dripping it onto the colloidal gold rapid test card. The scanning part is located above the first conveyor component 3.

[0031] The dripping part includes a turntable 41 that rotates perpendicular to the horizontal plane, and multiple dripping mechanisms 43 are rotatably connected to the bottom of the turntable 41 in a circular array.

[0032] With the above technical solution, when personnel need to scan the colloidal gold rapid test card, the different samples to be tested are placed one by one into each sample cup, and the sample cups are placed one by one onto the second conveyor 2. Then, the colloidal gold rapid test card is placed one by one onto the first conveyor 3. The operation of the second conveyor 2 and the first conveyor 3 respectively drives the sample cups and colloidal gold rapid test cards to move. The rotation of the turntable 41 drives the dispensing mechanism 43 to rotate, causing the dispensing mechanism 43 to move above the sample cup. The dispensing mechanism 43 then picks up the sample from the sample cup, and the sample is transferred to the turntable 41 by rotation. This causes the dispensing mechanism 43 to rotate, moving the sample above the colloidal gold rapid test card. The liquid is then dispensed onto the colloidal gold rapid test card by the dispensing mechanism 43. As the sample is moved by the dispensing mechanism 43, the turntable 41 moves other dispensing mechanisms 43 to another sample cup to pick up other samples, allowing the device to operate continuously. After the sample is dispensed onto the colloidal gold rapid test card, the first conveyor 3 continues to move the colloidal gold rapid test card forward, and the scanning part scans and identifies the test results on the colloidal gold rapid test card.

[0033] Specifically, in one embodiment, regarding the aforementioned scanned document 4, as... Figures 1-2 , Figures 6-7 As shown, the scanning device 4 also includes a base plate 45, on which an electric telescopic rod 49 is fixedly connected. A connecting plate 44 is fixedly connected to the telescopic end of the top of the electric telescopic rod 49. A connecting plate 44 is fixedly connected to the top of the connecting plate 44. A third motor 42 is fixedly connected to one side of the connecting plate 44. The output end of the third motor 42 is fixedly connected to the top of the turntable 41.

[0034] In this embodiment, the electric telescopic rod 49 operates, thereby moving the connecting plate 44. The connecting plate 44 then moves the third motor 42, which in turn moves the dispensing mechanism 43 downward, allowing it to move into the sample cup to extract the sample. The third motor 42 operates, thereby rotating the turntable 41. The turntable 41 then rotates the dispensing mechanism 43, causing it to rotate the sample onto the colloidal gold rapid test card. The sample is then dispensed onto the colloidal gold rapid test card for detection.

[0035] To facilitate cleaning of the dripping mechanism 43, such as Figures 1-2 , Figures 6-7 As shown, a water storage tank 48 is placed on top of the substrate 45. The top of the water storage tank 48 is open to form a liquid storage cavity for storing cleaning fluid, and the water storage tank 48 is located below one of the dripping mechanisms 43.

[0036] In this embodiment, when the dripping mechanism 43 rotates and the electric telescopic rod 49 works, the electric telescopic rod 49 drives the connecting plate 44 and the third motor 42 to move, thereby causing the turntable 41 to drive the dripping mechanism 43 to move down, so that the dripping mechanism 43 moves into the liquid storage chamber in the water storage tank 48, thereby allowing the dripping mechanism 43 to be cleaned during the movement, which is convenient for continuous operation.

[0037] Specifically, in one embodiment, regarding the aforementioned scanning portion, such as Figures 1-2 , Figures 6-7 As shown, the scanning part includes a support frame 46, the bottom of which is fixedly connected to the top of the substrate 45, and a vision camera 47 is fixedly connected to the top of the support frame 46.

[0038] In this embodiment, after the colloidal gold rapid test card carrying the sample moves to below the scanning section, it is supported by the substrate 45 on the support frame 46, and the support frame 46 supports the vision camera 47. The vision camera 47 scans and identifies the sample.

[0039] Furthermore, in this utility model, regarding the aforementioned second conveying member 2, as follows: Figure 1 , Figure 2 and Figure 4 As shown, the second conveyor 2 includes a second mounting frame 24, and two second drive rollers 23 are symmetrically rotatably connected inside the second mounting frame 24. A second conveyor belt 22 is sleeved between the two second drive rollers 23.

[0040] In this embodiment, when it is necessary to move the sample cup, the second mounting bracket 24 supports the second transmission roller 23, the second transmission roller 23 drives the second conveyor belt 22 to rotate, and the second conveyor belt 22 drives the sample cup to move.

[0041] When the second conveyor belt 22 transports the sample cup, in order to make the sample cup more stable during the movement, such as Figures 1-2 and Figure 4 As shown, the outer side of the second conveyor belt 22 is arranged in a ring-shaped array to form multiple positioning grooves 25.

[0042] In this embodiment, when the second conveyor belt 22 moves the sample cup, the positioning groove 25 makes the movement of the sample cup by the second conveyor belt 22 more stable.

[0043] Specifically, in one embodiment, regarding the first conveying member 3 described above, as... Figures 1-3 As shown, the first conveying component 3 includes a first mounting frame 31, and two first drive rollers 32 are symmetrically rotatably connected inside the first mounting frame 31. A first conveyor belt 33 is sleeved between the two first drive rollers 32.

[0044] In this embodiment, when it is necessary to move the colloidal gold rapid test card, the first mounting frame 31 supports the first transmission roller 32, the first transmission roller 32 drives the first conveyor belt 33 to rotate, and the first conveyor belt 33 drives the colloidal gold rapid test card to move.

[0045] When the first conveyor belt 33 moves the colloidal gold rapid test card, in order to make the movement of the colloidal gold rapid test card more stable, such as Figures 1-3 As shown, the outer side of the first conveyor belt 33 is arranged in a ring array to form multiple limiting strips 34, and two limiting blocks 35 are symmetrically protruded between two adjacent limiting strips 34. A placement cavity for placing the colloidal gold rapid test card is formed between two adjacent limiting strips 34 and two limiting blocks 35.

[0046] In this embodiment, after the personnel place the colloidal gold rapid test card above the first conveyor belt 33, the colloidal gold rapid test card is positioned by two limiting strips 34 and two limiting blocks 35, thereby making the movement of the colloidal gold rapid test card more stable.

[0047] Furthermore, in this utility model, regarding how the first transmission roller 32 and the second transmission roller 23 rotate, as follows: Figures 1-4 As shown, a first motor 36 is fixedly connected to the first mounting bracket 31, and the output end of the first motor 36 is connected to the first transmission roller 32. A second motor 21 is fixedly connected to the second mounting bracket 24, and the output end of the second motor 21 is connected to the second transmission roller 23.

[0048] In this embodiment, when it is necessary to drive the first transmission roller 32 to rotate, the first motor 36 works, thereby driving the first transmission roller 32 to rotate. When it is necessary to drive the second transmission roller 23 to rotate, the second motor 21 works, thereby driving the second transmission roller 23 to rotate.

[0049] Specifically, in one embodiment, regarding the aforementioned support member 1, as... Figures 1-2 and Figure 5 As shown, the support member 1 includes a base 11, with a foot 12 fixedly connected to the bottom of the base 11 for supporting itself, and a second collection box 13 and a first collection box 14 fixedly connected to one side of the base 11, with the second collection box 13 located on one side of the first collection box 14.

[0050] In this embodiment, the base 11 is supported by the foot 12, and the second collection box 13 and the first collection box 14 are supported by the base 11. The used colloidal gold rapid test card is collected by the second collection box 13, and the used sample cup is collected by the first collection box 14.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
