[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] like Figures 1 to 5 As shown, a visual inspection device includes: a frame 4, a visual inspection component 1, a guiding mechanism 3, and a sorting mechanism 2; the frame 4 is provided with a conveyor belt 5, which is used to transport reagent cards 7 to be tested; the visual inspection component 1 is disposed on the frame 4 and is located close to the conveyor belt 5; the visual inspection component 1 is used to capture images of the reagent cards 7 to be tested; the guiding mechanism 3 is disposed on the conveyor belt 5, and the guiding mechanism 3 has a guide groove 33; the guide groove 33 is used to accommodate the reagent cards 7 to be tested; the sorting mechanism 2 is disposed on the frame 4 and is located at the discharge end of the conveyor belt 5, for sorting qualified reagent cards and unqualified reagent cards after testing.

[0045] The frame 4 provides a stable structural support, ensuring the installation and positioning of all components. The vision inspection component 1 is responsible for capturing the state of the test reagent card 7 during its transport on the conveyor belt 5, while the guide mechanism 3 ensures that the test reagent card 7 maintains the correct positioning and orientation during transport. In other words, under the guidance and positioning of the guide mechanism 3, the vision inspection component 1 can accurately capture images of the test reagent card 7 for inspection. Subsequently, the sorting mechanism 2 classifies the reagent cards as qualified or unqualified based on the inspection results of the vision inspection component 1. Through the coordinated work of the frame 4, vision inspection component 1, guide mechanism 3, and sorting mechanism 2, this device automates the entire process from reagent card transport and inspection to sorting, greatly reducing human intervention, improving inspection efficiency, avoiding visual fatigue caused by prolonged manual inspection, and enhancing the accuracy and stability of the inspection.

[0046] Furthermore, the visual inspection component 1 includes a first camera 12 and a second camera 11. The first camera 12 is mounted on the frame 4 and located above the guide mechanism 3 to inspect the upper surface of the reagent card 7 to be tested, mainly checking for scratches or other defects on the upper surface of the reagent card to ensure the quality of the upper surface of the reagent card. The second camera 11 is mounted on the frame 4 and located to the side of the conveyor belt 5 to inspect the side of the reagent card 7 to be tested, checking for impurities or other defects in the reagent inside the side hole to ensure the quality of the side of the reagent card. In other words, through the cooperation of these two camera units, multi-faceted inspection of the reagent card is achieved. In addition, to ensure that the first camera 12 and the second camera 11 can capture the details on the surface of the reagent card more clearly, stable light sources are provided for both the first camera 12 and the second camera 11. The relative positions of the light sources with respect to the first camera 12 and the second camera 11 are adjustable, and can be adjusted vertically, horizontally, and angularly. The light source can be an LED light, but is not limited to it. It can be installed around the first camera 12 and the second camera 11 respectively to provide a uniform and stable light source, thereby improving the accuracy of detection.

[0047] Furthermore, there are two first cameras 12, arranged along the transport direction of the reagent card 7 to be tested. These two first cameras 12 can simultaneously detect different areas on the surface of the reagent card; alternatively, one first camera 12 can detect different areas on the surface of the reagent card, while the other first camera 12 re-inspects the already detected reagent cards to ensure accuracy and prevent any possible omissions or errors. It should be noted that the number of first cameras 12 includes, but is not limited to, two. If the frame 4 fixing their positions is long enough, the first cameras 12 can still be arranged in parallel, extending their detectable area and allowing simultaneous detection of multiple reagent cards.

[0048] And / or, there are at least two second cameras 11, and the second cameras 11 are respectively provided on opposite sides of the conveyor belt 5; that is, at least one second camera 11 is provided on each side of the conveyor belt 5, and these cameras are used to detect the card surfaces on the left and right sides of the reagent card respectively, ensuring that the test reagent card is detected from different angles.

[0049] The above embodiments, by providing multiple first cameras 12 and multiple second cameras 11, can simultaneously detect multiple sides of the reagent card. This not only improves the detection speed but also reduces the time required for manual detection, avoiding visual fatigue that may be caused by prolonged manual detection, thereby improving the accuracy and stability of the detection.

[0050] Furthermore, the guiding mechanism 3 includes two guide rails 32 and an adjusting component 31; the two guide rails 32 are located above the conveyor belt 5 and are spaced apart to form the guide groove 33, so as to ensure that the test reagent card 7 can move along a predetermined path on the conveyor belt 5; each of the guide rails 32 is connected to the frame 4 through the adjusting component 31, so that the position of the guide rail 32 can be easily adjusted to accommodate test reagent cards 7 of different sizes.

[0051] Furthermore, the adjustment component 31 includes: an adjustment block and a telescopic rod; the adjustment block is disposed on the frame 4; one end of the telescopic rod is connected to the adjustment block, and the other end is connected to the guide rail 32; by operating the adjustment block, the telescopic rod's extension and retraction amount is adjusted, thereby adjusting the position of the guide rail 32, thus adjusting the relative position between the guide rail 32 and the frame 4, and further adjusting the width of the guide groove 33 to accommodate reagent cards of different sizes.

[0052] Furthermore, the guide rail 32 is provided with a guide part 34 facing the feed end of the conveyor belt 5. The two guide parts 34 are respectively located at the front end of the two guide rails 32 and facing the feed end of the conveyor belt 5 to ensure that the reagent card 7 to be tested can smoothly enter the guide groove 33. The two guide parts 34 are symmetrically arranged, and each guide part 34 is inclined from the outside to the inside of the guide rail 32 to form a gradually narrowing funnel-shaped opening, which is conducive to smoothly transitioning the reagent card 7 to be tested into the guide groove 33, ensuring its stability in the subsequent testing process, thereby ensuring that the reagent card can be successfully tested.

[0053] To further explain, in order to ensure that the reagent card 7 to be tested is within the detection area of ​​the first camera 12 and the second camera 11 when being tested on the conveyor belt 5, the following method can be adopted: The guide groove 33 is installed below the first camera 12 and the second camera 11, ensuring that the reagent card 7 to be tested is always within the detection range of the first camera 12 and the second camera 11 as it passes through the conveyor belt. Furthermore, the position of the reagent card on the conveyor belt 5 can be further ensured to be accurate by flexibly adjusting the adjusting component 31, thereby ensuring that the position and orientation of the reagent card 7 to be tested meet the detection requirements when passing through the camera detection area, thus improving the accuracy and efficiency of the detection.

[0054] Furthermore, it also includes a pre-guiding mechanism 6, which is located on one side of the guiding mechanism 3 and close to the feed end of the conveyor belt 5; wherein, the pre-guiding mechanism 6 includes two guiding components, which are arranged symmetrically; it can start to function as soon as the test reagent card 7 enters the conveyor belt, ensuring that it smoothly enters the subsequent guiding mechanism 3.

[0055] Specifically, the pre-guiding mechanism 6 consists of two guiding components designed in a symmetrical layout to form a gradually narrowing channel; the test reagent card 7 can be initially adjusted and guided from both sides of the channel simultaneously to ensure that it is roughly centered before entering the guiding mechanism, thus preparing it for the subsequent guiding process.

[0056] In further detail, during use, the reagent card 7 to be tested is placed in the reagent card placement area of ​​the conveyor belt 5. Under the dual guidance of the pre-guiding mechanism 6 and the further guidance and correction of the guiding mechanism 3, the reagent card 7 to be tested moves smoothly along the predetermined path on the conveyor belt 5, and smoothly enters the working area of ​​the first camera 12 and the second camera 11 to complete the test.

[0057] Furthermore, the sorting mechanism 2 includes a drive component 22 and a pusher assembly 21; the drive component 22 is disposed on the frame 4; the pusher assembly 21 is disposed on the frame 4 and located above the discharge end of the conveyor belt 5; the pusher assembly 21 is connected to the drive component 22; wherein, the drive component 22 drives the pusher assembly 21 to rotate, so as to sort the reagent cards on the discharge end of the conveyor belt 5, thereby sorting out qualified reagent cards and unqualified reagent cards after testing.

[0058] Furthermore, the pusher assembly 21 includes: a rotating frame 211, a baffle 212, and a sensor 213; the rotating frame 211 is connected to the drive member 22; the baffle 212 is disposed on the rotating frame 211; wherein, the drive member 22 drives the rotating frame 211 to rotate, and drives the baffle 212 to rotate, so as to push the reagent card on the discharge end of the conveyor belt 5; the sensor 213 is disposed on the rotating frame 211 and is used to detect the position of the baffle 212.

[0059] Specifically, such as Figures 4 to 5 As shown, the baffle 212 includes a first baffle, a second baffle, and a third baffle; the sensor 213 is an optocoupler sensor, which is mounted on the rotating frame 211 near the first baffle. The first baffle on the rotating frame 211 is taken as the origin of the sorting mechanism 2, serving as the reference point for the entire sorting process. The second baffle remains stationary under normal conditions, allowing qualified reagent cards to pass smoothly through the sorting area. The third baffle works in conjunction with other baffles to adjust its position when unqualified reagent cards need to be rejected. That is, when the third baffle moves to the position of the first baffle, the optocoupler sensor can detect its position and trigger the sorting operation. In the normal state: the first baffle is located at the reference point. The second baffle is located below, allowing qualified reagent cards to pass through. The third baffle is in a ready position, awaiting instructions.

[0060] Removing unqualified reagent cards: When an unqualified reagent card is detected, the sorting mechanism 2 is activated, causing the rotating frame 211 to rotate the baffle 212. Specifically, the first baffle moves to the position of the second baffle, the second baffle moves to the position of the third baffle, and the third baffle moves to the position of the first baffle. After the third baffle reaches its origin position, it is detected by the photocoupler sensor. At this point, the sorting mechanism has completed the removal of one unqualified item, and the third baffle remains at its origin position until another unqualified item is detected by the vision inspection component 1. Then, the sorting mechanism 2 is activated again, causing the rotating frame 211 to rotate the baffle 212, and the unqualified item is removed again.

[0061] Furthermore, it also includes a receiving device for receiving and accommodating reagent cards, located below the discharge end of the conveyor belt 5. After the reagent card 7 to be tested has completed its movement on the conveyor belt and passed through the detection process of the first camera 12 and the second camera 11 in sequence, and the sorting mechanism 2 confirms that the reagent card is a qualified product, the reagent card will continue to run along the predetermined path until it finally falls safely into the receiving device below.

[0062] The above description describes specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
