Description

Technical Field

[0001] The present invention relates to the technical field of biological equipment, and particularly to a sedimentation chamber sampling and propulsion mechanism, an automatic sorting device, and an automatic sorting method. Background Art

[0002] As people pay more and more attention to the understanding of diseases, accurate diagnosis of physical conditions has become a decisive basis for measuring the state of physical health. Therefore, the examination of pathological tissues is very important for the confirmation and diagnosis of diseases. It is necessary to make slides for the examination of pathological cells. There are smear slide-making methods, imprint slide-making methods, sedimentation slide-making methods, etc. Among them, sedimentation slide-making is divided into natural sedimentation slide-making and centrifugal sedimentation slide-making. The so-called natural sedimentation slide-making is to place a cell-containing solution in a container, and the cells in the solution settle to the bottom of the solution under the action of gravity. After the cell sedimentation is completed, the supernatant is poured off or sucked off, and the cells at the bottom of the container are the cell smear. The centrifugal sedimentation method is to place the cell-containing solution in a container and then place the container in a centrifuge for centrifugation, so that the cells in the container accelerate to the bottom of the container under the action of centrifugal force. After the sedimentation is completed, the supernatant is poured off or sucked off to obtain the cell smear.

[0003] Sorting the sedimentation chambers can separate the used sedimentation chambers from the unused ones for further processing. However, the shape of the sedimentation chambers is special, and visual recognition and analysis need to be carried out from the top to complete the sorting of the sedimentation chambers. When using an ordinary conveyor belt for transmission, it is difficult to ensure that the sedimentation chambers always remain in a vertical state during the transmission process. Therefore, a sedimentation chamber sampling and propulsion mechanism, an automatic sorting device, and an automatic sorting method are proposed. Summary of the Invention

[0016] An automatic sorting method for a sedimentation bin includes the following steps: S1.

Then, the lifting servo motor is started to rotate the lifting lead screw, thereby driving the lifting thread sleeve and the lifting column to move downward until the lifting column is inserted into the sedimentation bin, and the lifting servo motor is turned off. S2. Subsequently, the sorting servo motor is started. The sorting lead screw is driven to rotate by the sorting servo motor, so that the sorting thread sleeve moves backward, and the sedimentation bin moves backward accordingly. The sedimentation bin presses against the limiting plate, causing the limiting plate to rotate around the hinge position until the sedimentation bin no longer contacts the limiting plate. Then, the limiting plate is reset by the torsion spring. The sedimentation bin moves along the top surfaces of the first sorting guide plate and the second sorting guide plate and passes through the two sorting baffles, and then enters the flow grooves of the two flow blocks until the sedimentation bin enters the limiting holes. S3. The extrusion servo motor is started to drive the extrusion lead screw to rotate, so that the extrusion thread sleeve and the extrusion push block move downward until the extrusion push block contacts the four limiting pieces and presses the four limiting pieces downward, causing the intermediate block to move downward along the outer sides of the two columns, so that the sedimentation bin is no longer limited by the limiting holes. S4.1. The sorting servo motor drives the sorting lead screw to continue rotating, and the sedimentation bin continues to move backward until the sedimentation bin moves above the guide plate and falls into the guide plate, and then falls onto the second belt. The transmission motor is started, and the power of the transmission motor is transmitted to the front rotating shaft through the second pulley transmission mechanism, thereby driving the second belt to move, so that the sedimentation bin is transmitted to the discharge bin and is collected after falling out of the discharge bin. S4.2. The lifting servo motor drives the lifting lead screw to rotate in the reverse direction, thereby driving the lifting thread sleeve and the lifting column to move upward until the lifting column disengages from the inside of the sedimentation bin, and the sedimentation bin is taken away from the flow groove by the robotic arm.

[0017] (III) Beneficial effects Compared with the prior art, the technical solution of the present application has the following beneficial technical effects: 1. By providing a first guiding slit and a second guiding slit, the sedimentation bin of the present invention always maintains a vertical state before sorting, which facilitates visual inspection and recognition from the top surface and facilitates sorting thereof.

[0018] 2. By setting the top surface of the guiding plate as an inclined surface, the sedimentation bin can slide from left to right along the top surfaces of the two guiding plates under the action of gravity, eliminating the need for an additional power source to push the sedimentation bin onto the two first belts, thereby reducing energy consumption.

[0019] 3. By means of the rejection push block, during the process of the rejection push block moving leftward, the sedimentation bin in the wrong position will be knocked from above the two first belts into the bin box, preventing the sedimentation bin from jamming at the connection between the bin box and the feeding mechanism and affecting subsequent normal transmission.

[0032] An automatic sorting method for a sedimentation bin includes the following steps: S1. First, the sedimentation bins are pushed one by one to the limiting plate 717 through the sample injection pushing mechanism, and then the lifting servo motor 78 is started to rotate the lifting lead screw 738, thereby driving the lifting thread sleeve 710 and the lifting column 711 to move downward until the lifting column 711 is inserted into the sedimentation bin, and then the lifting servo motor 78 is turned off; S2. Subsequently, the sorting servo motor 75 is started. The sorting lead screw 76 is driven by the sorting servo motor 75 to rotate, so that the sorting thread sleeve 77 moves backward, and the sedimentation bin moves backward accordingly. The sedimentation bin presses against the limiting plate 717, causing the limiting plate 717 to rotate around the hinge position until the sedimentation bin no longer contacts the limiting plate 717. Then, the limiting plate 717 is reset by the torsion spring 720.

The sorting servo motor 75 drives the sorting lead screw 76 to continue rotating, and the sedimentation bin continues to move backward until the sedimentation bin moves above the material guiding plate 737 and falls into the material guiding plate 737, and then falls above the second belt 85. The transmission motor 87 is started, and the power of the transmission motor 87 is transmitted to the front rotating shaft 83 through the second belt pulley transmission mechanism 88, thereby driving the second belt 85 to move, so that the sedimentation bin is transmitted to the discharge bin 89 and is collected after falling out of the discharge bin 89; S4.2. Drive the lifting lead screw 738 to rotate reversely through the lifting servo motor 78, thereby driving the lifting threaded sleeve 710 and the lifting column 711 to move upward until the lifting column 711 disengages from the inside of the sedimentation bin, and then remove the sedimentation bin from the transfer chute 727 by the robotic arm.

[0033] One of the sedimentation bin sampling and propulsion mechanisms pushes the sedimentation bins to the limiting plate 717 one by one, including the following steps: First, place some sedimentation bins into the bin box 1. The sedimentation bins fall into the first guiding slot 23. Start the jacking servo motor 52 to rotate the jacking lead screw 55, and then drive the jacking threaded sleeve 56 to move upward. Due to the gravity, the sedimentation bins slide from left to right along the top surfaces of the two guide plates 21 until they slide onto the two first belts 38. The cylindrical main body of the sedimentation bin is located in the second guiding slot 310. Start the feeding motor 36 to drive the linkage pulley 37 to rotate, and then the two first belts 38 drive the sedimentation bin to move. The jacking servo motor 52 rotates reversely to drive the jacking lead screw 55 to rotate reversely, and then drive the jacking threaded sleeve 56 to move downward to reset. At the same time, start the rejection servo motor 65. Drive the rejection lead screw 66 to rotate through the rejection servo motor 65, and then drive the rejection threaded sleeve 67 to move leftward, so that the rejection push block 68 moves leftward. During the process of the rejection push block 68 moving leftward, the sedimentation bins with incorrect positions will be knocked from above the two first belts 38 into the bin box 1, while the sedimentation bins with correct positions will be normally driven by the two first belts 38 to move to the limiting plate 717.

[0034] In addition, it should be noted that during the sorting process, the visual recognition and processing technology needs to be used to automatically analyze the sedimentation bins. If the sedimentation bin is analyzed as used, perform step S4.1; if the sedimentation bin is not used, perform step S4.2. The whole process is controlled by the controller, and the specific control process is the existing technology, so it will not be elaborated here.
