[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions 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 scope of protection of this utility model.

[0035] The following is combined Figures 1-2 The visual extraction and separation device provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0036] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a visual extraction and separation device, including: a support 1, a lifting module 2, a pumping assembly 3, a first container 4, and a second container 5;

[0037] The lifting module 2 is equipped with a suction tube 100 and a vision detection element 200. The suction tube 100 is used to extend into the first container 4 under the drive of the lifting module 2; the detection end of the vision detection element 200 faces the suction end of the suction tube 100.

[0038] The support 1 is provided with a liquid outlet head 300. The liquid outlet end of the suction pipe 100 is connected to the liquid outlet head 300 through the pumping assembly 3. The liquid outlet head 300 is configured to discharge liquid into the second container 5.

[0039] The visual detection element 200 is used to identify the color of the liquid in the first container 4, and the visual detection element 200 is electrically connected to the lifting module 2 and the pumping assembly 3.

[0040] Understandably, the bracket 1 and the lifting module 2 can be configured to be spaced apart from each other and arranged side by side.

[0041] The lifting module 2 can adopt a telescopic rod or a screw lifting mechanism. The lifting end of the lifting module 2 is connected to the suction tube 100 and the vision detection element 200 respectively, so as to drive the suction tube 100 and the vision detection element 200 to move up and down synchronously. The suction tube 100 is set vertically, and the vision detection element 200 can be configured to be located on one side of the suction tube 100.

[0042] The bracket 1 provides a mounting support for the liquid outlet 300. The bracket 1 includes a vertical rod and a horizontal rod. The first end of the horizontal rod is connected to the top end of the vertical rod, and the second end of the horizontal rod is connected to the liquid outlet 300. The liquid outlet 300 is configured to discharge liquid vertically downward toward the second container 5.

[0043] The pumping assembly 3 can be a peristaltic pump, and the suction tube 100 is connected to the outlet head 300 through the peristaltic pump. In practical applications, the suction tube 100 performs the suction operation of the liquid to be extracted from the test sample and the vision detection element 200 performs the color recognition of the test sample simultaneously. As the suction tube 100 performs the suction operation, the liquid level in the first container 4 decreases. The lifting module 2 controls the suction tube 100 to descend according to the detection result fed back by the vision detection element 200, so that the suction end of the suction tube 100 is always in the liquid area where the liquid to be extracted is located.

[0044] The visual detection element 200 can be a camera or color sensor known in the art, and the first container 4 and the second container 5 can be a beaker or a measuring cup.

[0045] The visual extraction and separation device provided by this utility model consists of a support 1, a lifting module 2, and a pumping assembly 3. The lifting module 2 is equipped with a suction tube 100 and a visual detection element 200, while the support 1 is equipped with a liquid outlet 300. The lifting module 2 drives the suction tube 100 to extend into the first container 4. The visual detection element 200 identifies the color of the liquid area where the suction end of the suction tube 100 is located. Based on the identification result of the visual detection element 200, the lifting module 2 controls the suction end of the suction tube 100 to be at a height corresponding to the liquid to be extracted. Then, the pumping assembly 3 drives the liquid to be extracted from the first container 4 to the second container 5, thereby realizing the extraction and separation of the liquid to be extracted.

[0046] As can be seen from the above, the visual extraction and separation device shown in this utility model can automatically extract and separate the liquid to be extracted from the test sample without human intervention. It is not only highly efficient, but also ensures the accuracy of the extraction and separation of the test sample.

[0047] In some embodiments, such as Figure 1 and Figure 2As shown, the lifting module 2 includes a linear motor module that extends vertically. The suction tube 100 and the vision detection element 200 are respectively connected to the slide of the linear motor module. The slide of the linear motor module drives the suction tube 100 and the vision detection element 200 to move up and down synchronously in the vertical direction.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the first container 4 is a transparent graduated tube, the suction tube 100 is configured to extend into the graduated tube, and the visual detection element 200 is configured to be located outside the graduated tube.

[0049] Understandably, the first container 4 uses a transparent graduated tube, which ensures that the suction tube 100 can perform the suction operation normally without affecting the visual detection element 200 to see through the graduated tube and identify the color of the liquid inside.

[0050] Meanwhile, in practical applications, since the side wall of the graduated tube is provided with graduation lines, the pumping assembly 3 can be controlled to quantitatively extract the liquid to be extracted from the graduated tube according to the markings provided by the graduation lines.

[0051] In some embodiments, such as Figure 1 As shown, the vision detection element 200 includes an RGB camera and an image processor electrically connected. The image processor is electrically connected to the lifting module 2 and the pumping assembly 3, respectively. The RGB camera is used to acquire images of the liquid area where the suction end of the suction tube 100 is located, and the image processor is used to determine the color of the liquid area based on the image.

[0052] Understandably, the lens of the RGB camera is horizontally positioned and can be set at the same height as the suction end of the suction tube 100. The RGB camera can be an IMX226 sensor, and the image processor can be an IMX500.

[0053] In practical applications, the RGB camera is used to acquire color images of the liquid area where the suction end of the suction tube 100 is located. The image processor can use color recognition algorithms known in the art (such as spatial transformation, feature extraction, color classification and color segmentation) to process the color image, identify the color of the liquid area where the suction end of the suction tube 100 is located, thereby determining the distribution range of the liquid area, and then controlling the lifting module 2 to adjust the height position of the suction end of the suction tube 100, as well as controlling the start and stop of the pumping component 3.

[0054] It should be noted that the image processor's recognition and processing of color images captured by RGB cameras is existing technology and is not an improvement of this utility model patent.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the second container 5 includes a triangular bottle, and the outlet head 300 is positioned at a height higher than the mouth of the triangular bottle.

[0056] In some embodiments, such as Figure 2 As shown, the pumping assembly 3 includes a syringe pump 31 and a three-way valve 32; the outlet end of the suction tube 100 is connected to the first port of the three-way valve 32, the second port of the three-way valve 32 is connected to the syringe pump 31, and the third port of the three-way valve 32 is connected to the outlet head 300.

[0057] The three-way valve 32 has a first state and a second state. When the three-way valve 32 is in the first state, the first port and the second port of the three-way valve 32 are connected. When the three-way valve 32 is in the second state, the third port and the second port of the three-way valve 32 are connected.

[0058] Understandably, in the initial stage, the three-way valve 32 is in the first state. Driven by the injection pump 31, the liquid to be extracted in the first container 4 enters the injection pump 31 through the suction tube 100 and the three-way valve 32 in sequence, so as to realize the suction of the liquid to be extracted in the first container 4.

[0059] In the subsequent stage, the three-way valve 32 is in the second state. Driven by the injection pump 31, the liquid to be extracted collected in the chamber of the injection pump 31 enters the second container 5 through the three-way valve 32 and the liquid outlet 300 in sequence, thereby realizing the extraction and separation of the liquid to be extracted from the test sample.

[0060] Among them, the three-way valve 32 can be a two-position three-way solenoid valve.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the visual extraction and separation device further includes: a first linear slide module 6; the first linear slide module 6 is located on one side of the lifting module 2, and the slide of the first linear slide module 6 is used to place the first container 4; the first linear slide module 6 is used to control the first container 4 to move to or away from the suction tube 100.

[0062] Understandably, the first linear slide module 6 can be configured on a horizontal platform, with one end of the first linear slide module 6 located below the suction pipe 100.

[0063] When extracting the liquid to be extracted from the test sample, the first linear slide module 6 is used to move the first container 4 below the suction tube 100; after the extraction of the liquid to be extracted is completed, the first linear slide module 6 drives the first container 4 to leave from below the suction tube 100.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the visual extraction and separation device also includes: a first material level sensor 7; the first material level sensor 7 is disposed on one side of the first linear slide module 6 and is electrically connected to the first linear slide module 6.

[0065] The first material level sensor 7 is used to detect whether the first container 4 is placed on the slide of the first linear slide module 6.

[0066] Understandably, the first level sensor 7 can be a photoelectric sensor switch, and the first level sensor 7 is located at the end of the first linear slide module 6 away from the lifting module 2.

[0067] When the first container 4 is placed on the slide of the first linear slide module 6, the first level sensor 7 is triggered by the first container 4 and sends a trigger signal back to the first linear slide module 6. The first linear slide module 6 responds to the trigger signal and transports the first container 4 to the bottom of the suction pipe 100 through its slide.

[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, the visual extraction and separation device further includes: a second linear slide module 8; the second linear slide module 8 is disposed on one side of the support 1, and the slide of the second linear slide module 8 is used to place the second container 5; the second linear slide module 8 is used to control the second container 5 to move to or away from the liquid outlet 300.

[0069] Understandably, the second linear slide module 8 can be configured on a horizontal platform and arranged side by side with the first linear slide module 6, with one end of the second linear slide module 8 located below the liquid outlet head 300.

[0070] When extracting the liquid to be extracted from the test sample, while the first linear slide module 6 moves the first container 4 below the suction tube 100, the second linear slide module 8 moves the second container 5 below the liquid outlet 300; after the extraction of the liquid to be extracted is completed, the second linear slide module 8 drives the second container 5 to leave from below the liquid outlet 300.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the visual extraction and separation device also includes: a second material level sensor 9; the second material level sensor 9 is disposed on one side of the second linear slide module 8 and is electrically connected to the second linear slide module 8;

[0072] The second level sensor 9 is used to detect whether the second container 5 is placed on the slide of the second linear slide module 8.

[0073] Understandably, the second level sensor 9 can be a photoelectric sensor switch, and the second level sensor 9 is located at the end of the second linear slide module 8 away from the bracket 1.

[0074] When the second container 5 is placed on the slide of the second linear slide module 8, the second level sensor 9 is triggered by the second container 5 and sends a trigger signal back to the second linear slide module 8. The second linear slide module 8 responds to the trigger signal and conveys the second container 5 to the bottom of the liquid outlet head 300 through its slide.

[0075] The first linear slide module 6 and the second linear slide module 8 are both linear slide modules known in the art and will not be described in detail here.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
