The camera module 200 is arranged in the first darkroom 110, and the camera module 200 can shoot the container 700, so as to identify the quality of the sample in the container 700, when the sample is blood, there can be lipemia, hemolysis, jaundice, centrifugation, non-centrifugation and the like, and the image obtained by the camera module 200 can be used to determine which of the above conditions the blood is in, so as to know the quality condition of the blood. The shooting direction of the camera module 200 forms an angle with the first direction, and the shooting direction of the camera module 200 can be perpendicular to the first direction, so that the camera module 200 does not face the first opening 111 directly, avoiding the influence of the light entering from the first opening 111 on the imaging of the container 700.

[0043] In the process of using the sample quality identification device 1000, first, the container 700 is placed in the first darkroom 110 from the first opening 111, and the light emitting assembly 300 is turned on, so that the light emitting assembly 300 emits light to illuminate the container 700, at this time, the camera module 200 is aligned with the container 700 to shoot, the first darkroom 110 can shield the ambient light, the imaging of the container 700 on the camera module 200 is clear, thereby improving the imaging quality, which is conducive to the quality identification of the sample, the light emitting assembly 300 surrounds the outer periphery of the container 700, so that the light intensity of the container 700 in the circumferential direction is consistent, the difference in illumination intensity in different directions can be eliminated, the illumination intensity is balanced, the light is more uniform, and the imaging quality can be further improved, thereby improving the accuracy of identifying the quality of the sample.

[0044] It should be noted that the container 700 can be a test tube, a beaker or other utensils for holding samples. When the container 700 has an axis and is located in the first darkroom 110, the light-emitting assembly 300 can be understood as being arranged around the axis of the container 700, so that the light intensity of the light rays irradiated on the container 700 in the circumferential direction of the container 700 is uniform, the light rays are more uniform, and the imaging quality can be improved.

[0045] Referring to Figure 10 In some embodiments, the camera module 200 includes a camera 210 and a fixing plate 220, and the camera 210 is fixedly connected to the first darkroom 110 through the fixing plate 220.

The first light-emitting piece 310 emits light in the circumferential direction, and the second light-emitting piece 320 can be understood as a light bar. The plurality of second light-emitting pieces 320 are arranged along the circumferential direction of the first light-emitting piece 310. When the container 700 is located in the first darkroom 110, the first light-emitting piece 310 is located directly above the container 700, and the plurality of second light-emitting pieces 320 are located at the outer periphery of the first light-emitting piece 310. Such an arrangement makes the lighting effect on the container 700 better, and the imaging of the camera module 200 clearer. It can be understood that when the light-shielding box 100 is square, the second light-emitting piece 320 can be straight strip-shaped, and the plurality of second light-emitting pieces 320 are arranged at the edge positions of the top of the first darkroom 110, respectively.

Referring to Figure 3As shown, first, the pull-out plate 520 is pulled out, so that the cup 530 on the pull-out plate 520 is exposed outside the light shield cover 400, then the container 700 is placed into the cup 530, and then the pull-out plate 520 is pushed into the second dark chamber 430 of the light shield cover 400, refer to Figure 4 As shown, the first sensor detects that the pull-out plate 520 is pushed into place, and the second sensor 5020 detects that the cup 530 has the container 700, at this time, the lifting mechanism 610 drives the clamping mechanism 620 to pass through the first opening 111, and drives the clamping mechanism 620 to descend to the position of the container 700, then the clamping mechanism 620 clamps the container 700, the lifting mechanism 610 drives the clamping mechanism 620 to ascend, refer to Figure 5 As shown, the container 700 is made to enter the first dark chamber 110, then the camera module 200 takes a photo of the container 700, at the same time, the rotating mechanism 630 drives the clamping mechanism 620 to rotate 360 degrees, so that the camera module 200 samples the container 700 from multiple angles, after the shooting is completed, the lifting mechanism 610 drives the clamping mechanism 620 to descend, the clamping mechanism 620 releases the container 700, and the container 700 is placed back into the cup 530, then the pull-out plate 520 is pulled out, and the container 700 in the cup 530 is taken out, so that the quality identification of the sample is completed.

[0066] In the embodiment, the container 700 is automatically transported into the first dark chamber 110 by the conveying mechanism, the operation process is simple, and the quality identification is fast and efficient, the conveying mechanism has a simple structure and low manufacturing cost.

[0067] In some embodiments, the color of the inner wall of the light shield box 100 is white, the color of the background in the imaging of the camera module 200 is white, and the contrast of the container 700 to the background in the image can be improved. In addition, except for the light-emitting assembly 300 and the container 700, the outer wall of other internal structural members located in the first dark chamber 110 is black, which is not easy to reflect light, thereby weakening the interference and influence of the internal structural members on the light source, forming a reliable image acquisition environment, so that the taken photo is clear, high in contrast and high in fidelity, thereby realizing high-quality blood quality identification.
