[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, inside, outside, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Some embodiments of the present invention provide a material unloading mechanism 1000, which is suitable for a fully automatic sample processing system. Figures 1 to 9 The unloading mechanism 1000 is illustrated.

[0040] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the unloading mechanism 1000 includes: an unloading plate 100 and a tube-pumping device 200, and the unloading plate 100 and the tube-pumping device 200 are arranged at intervals in the up-down direction, wherein the unloading plate 100 is arranged to be tilted downward, so that the test tube 2000 located on the unloading plate 100 slides down along the unloading plate 100 under the action of gravity, thereby realizing the unloading of the test tube 2000. However, when the staff fails to completely affix the barcode to the test tube 2000, the adhesive backing of the barcode is exposed, or when there are burrs or dirt on the test tube 2000, the test tube 2000 is easily adhered to the unloading plate 100, making it difficult for the test tube 2000 to slide normally. The test tube 2000 stranded on the unloading plate 100 will affect the unloading of the next test tube 2000, increasing the risk of failure of the unloading mechanism 1000.

[0041] For this purpose, refer to Figure 2 , Figure 3 and Figure 4As shown, in the embodiment of the utility model, the blanking plate 100 is tilted downward toward the front side, and the test tube 2000 located on the blanking plate 100 can slide down in the front-to-back direction. The blanking plate 100 is provided with a through slot 110 extending along its tilting direction, that is, the through slot 110 is extended in the front-to-back direction, and the through slot 110 passes through the upper end surface and the lower end surface of the blanking plate 100. The through slot 110 can be provided in the middle of the blanking plate 100, or can be provided at a position close to the end of the blanking plate 100. The tube-pulling device 200 is provided on the lower side of the blanking plate 100, wherein the tube-pulling device 200 includes a tube-pulling member 210, and the upper end of the tube-pulling member 210 is penetrated through the through slot 110. In this embodiment, the tube-moving member 210 can drive its upper end to move along the through slot 110. For example, the tube-moving member 210 can move in the front-to-back direction, thereby driving its upper end to move along the through slot 110; the tube-moving member 210 can also rotate in the left-right direction, thereby driving its upper end to move along the through slot 110.

[0042] Reference Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the pipe-pulling member 210 has a first position and a second position, and the pipe-pulling member 210 can switch back and forth between the first position and the second position. It can be understood that in the process of switching the pipe-pulling member 210 from the first position to the second position, the upper end of the pipe-pulling member 210 moves from the top end 111 of the through slot 110 toward the bottom end 112 of the through slot 110. In this embodiment, the pipe-pulling member 210 can be set to delay start. It can be understood that the pipe-pulling member 210 can be set with a delay time, and the pipe-pulling member 210 drives its upper end to move along the through slot 110 after the preset delay time. For example, after the test tube 2000 falls into the blanking plate 100, the pipe-pulling member 210 can drive its upper end to move along the through slot 110 after a period of time, thereby reducing the possibility of the test tube 2000 being retained.

[0043] Specifically, refer to Figure 6 and Figure 7 As shown, when the tube-pushing member 210 is in the first position, in order to prevent the upper end of the tube-pushing member 210 from hindering the normal sliding of the test tube 2000, the upper end of the tube-pushing member 210 is located at the top end 111 of the through slot 110 and is lower than the upper end surface of the blanking plate 100. At this time, the test tube 2000 not adhered to the blanking plate 100 can slide directly along the blanking plate 100. It should be noted that in this embodiment, the first position can be the starting position of the tube-pushing member 210.

[0044] Reference Figure 8 and Fig. 9As shown, when the tube-pushing member 210 is in the second position, the upper end of the tube-pushing member 210 passes through the through slot 110 and protrudes from the upper end surface of the blanking plate 100. It can be understood that in the process of switching the tube-pushing member 210 from the first position to the second position, the upper end of the tube-pushing member 210 gradually moves from the top end 111 of the through slot 110 toward the bottom end 112 of the through slot 110. Since the blanking plate 100 is tilted downward, the upper end of the tube-pushing member 210 can gradually protrude from the upper end surface of the blanking plate 100 when moving forward, thereby abutting against the test tube 2000 adhered to the blanking plate 100. The tube moving member 210 can continue to drive its upper end to move toward the bottom end 112 of the through groove 110, thereby moving the test tube 2000 adhered to the blanking plate 100, causing the test tube 2000 remaining on the blanking plate 100 to slide off, reducing the possibility of the test tube 2000 remaining on the blanking plate 100, and effectively ensuring the normal operation of the blanking mechanism 1000.

[0045] Reference Figure 3 , Figure 4 and Figure 5 As shown, in the embodiment of the utility model, the pipe-pulling device 200 further includes a driver 220, and an output shaft 221 of the driver 220 is connected to the pipe-pulling member 210. Specifically, the output shaft 221 of the driver 220 is arranged in the pipe-pulling member 210 and is fixedly connected to the pipe-pulling member 210, so as to realize the synchronous rotation of the output shaft 221 and the pipe-pulling member 210. In this embodiment, the output shaft 221 is arranged along the left-right direction, so that the driver 220 can drive the pipe-pulling member 210 to rotate around the left-right direction, so that the pipe-pulling member 210 switches between the first position and the second position, and the upper end of the pipe-pulling member 210 switches between the top end 111 and the bottom end 112 of the through slot 110. It should be noted that the driver 220 can be a motor or a cylinder, and those skilled in the art can select and set it according to actual conditions, and this embodiment does not limit this.

[0046] Reference Figure 3 , Figure 4 and Figure 5As shown, in the embodiment of the utility model, the pipe-pulling device 200 further includes a rotating assembly 240 and a bracket 230, wherein the driver 220 is connected to the bracket 230 through a second fixing member 270. Specifically, the driver 220 is mounted on the second fixing member 270, and the second fixing member 270 is fixed to the bracket 230 through a fastener. For example, the fastener may be a screw, which is inserted into the second fixing member 270 and cooperates with the bracket 230 to achieve a fastening connection in a threaded connection. It should be noted that the fastener is not limited to a screw, but may also be a rivet, etc., which is not limited in this embodiment. In order to realize the rotation of the pipe-pulling member 210, the two ends of the pipe-pulling member 210 are rotatably connected to the bracket 230 through the rotating assembly 240. It can be understood that in this embodiment, two groups of rotating assemblies 240 are provided, and the two groups of rotating assemblies 240 are respectively connected to the two ends of the pipe-pulling member 210.

[0047] Specifically, refer to Figure 5 As shown, in the embodiment of the utility model, each set of rotating components 240 includes a pin shaft 241 and a retaining ring 242, wherein the pin shaft 241 is inserted through the bracket 230 and the pipe-pulling member 210 along the left-right direction, thereby realizing the rotational connection between the pipe-pulling member 210 and the bracket 230. In order to limit the movement of the pipe-pulling member 210 along the pin shaft 241, the retaining ring 242 is sleeved on the end of the pin shaft 241 away from the bracket 230. It should be noted that in the present embodiment, there may be a gap between the retaining ring 242 and the pipe-pulling member 210, or they may be connected to each other, which is not limited in the present embodiment. Figure 5 Taking the rotating assembly 240 on the left side as an example, when the pin 241 is displaced and moves to the left, the retaining ring 242 can abut against the pipe-shifting member 210 to limit the pin 241 from continuing to move to the left, which not only reduces the axial movement of the pipe-shifting member 210 along the pin 241, but also reduces the risk of the pin 241 falling off the pipe-shifting member 210 and the bracket 230.

[0048] Reference Figure 5 As shown, in the embodiment of the utility model, the rotating assembly 240 further includes a bearing 243 sleeved on the pin shaft 241. Specifically, the bearing 243 is disposed in the middle section of the pin shaft 241 and between the bracket 230 and the pipe-pulling member 210. The arrangement of the bearing 243 can reduce the friction between the bracket 230 and the pipe-pulling member 210, so that the rotation of the pipe-pulling member 210 is smoother. In the embodiment, the bearing 243 can be a rolling bearing or a sliding bearing, which is not limited in the embodiment.

[0049] Reference Figure 1 , Figure 2 and Figure 3As shown, in the embodiment of the utility model, the pipe-pulling device 200 further includes a photoelectric switch 250 connected to the bracket 230. Specifically, the photoelectric switch 250 can be connected to the bracket 230 through a first fixing member 260. Specifically, the photoelectric switch 250 is installed on the first fixing member 260, and the first fixing member 260 is fixed to the bracket 230 through a fastener. For example, the fastener can be a screw, which is inserted into the first fixing member 260 and cooperates with the bracket 230 to achieve a fastening connection in a threaded connection. It should be noted that the fastener is not limited to a screw, but can also be a rivet, etc., which is not limited in this embodiment. In this embodiment, the photoelectric switch 250 is used to detect the starting position of the pipe-pulling member 210. Specifically, the photoelectric switch 250 can limit the starting position of each stroke of the pipe-pulling member 210, even if each rotation of the pipe-pulling member 210 starts from the first position.

[0050] Specifically, refer to Figure 5 As shown, in the embodiment of the utility model, the lower end of the pipe-pulling member 210 is provided with a trigger portion 212 protruding downward, and the trigger portion 212 swings along with the rotation of the pipe-pulling member 210. It should be noted that the photoelectric switch 250 has an emitting end for emitting light and a receiving end for receiving light. Figure 3 As shown, when the tube-pulling member 210 is in the first position, the trigger portion 212 swings to between the transmitting end and the receiving end of the photoelectric switch 250, blocking the transmitting end from emitting light to the receiving end, thereby triggering the photoelectric switch 250. The photoelectric switch 250 confirms that the tube-pulling member 210 moves to the starting position and sends a command to the driver 220, causing the driver 220 to stop driving the tube-pulling member 210 to rotate.

[0051] Reference Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the blanking plate 100 is provided with two through slots 110 arranged at intervals, and the two through slots 110 are respectively arranged at positions near the ends of the blanking plate 100 at both ends. Correspondingly, the upper end of the tube-pushing member 210 is constructed as two protrusions 211 arranged at intervals, the two protrusions 211 protrude upward, and the two protrusions 211 are correspondingly arranged in the two through slots 110. When the two protrusions 211 protrude from the upper end surface of the blanking plate 100, the two ends of the test tube 2000 can be moved in coordination to balance the thrust on the test tube 2000, so that the test tube 2000 slides forward in the front-back direction, reducing the risk of the test tube 2000 tilting when sliding.

[0052] Reference Figure 1 and Figure 2As shown, in the embodiment of the utility model, the unloading mechanism 1000 further includes a feeding device 300, and the unloading plate 100 is arranged on the upper part of the feeding device 300, and the feeding device 300 is used to transport the test tube 2000 to the unloading plate 100. The feeding device 300 is provided with two side plates 310 arranged at intervals, and the tube-pulling device 200 is arranged between the two side plates 310. In this embodiment, the tube-pulling device 200 is fixedly connected to at least one of the side plates 310.

[0053] The embodiment of the present utility model further provides a fully automatic sample processing system, including the unloading mechanism 1000 of the above embodiment. In this embodiment, the fully automatic sample processing system can perform various fully automatic operations on the test tube 2000 samples, which can specifically include the transportation, storage and sorting of the test tube 2000 samples, and this embodiment does not limit this.

[0054] The blanking plate 100 of the fully automatic sample processing system of the present invention is provided with a through slot 110 extending along its inclined direction. The tube-pulling device 200 provided at the lower side of the blanking plate 100 includes a tube-pulling member 210. The upper end of the tube-pulling member 210 is passed through the through slot 110 and can move along the through slot 110. When the tube-pulling member 210 is in the first position, the upper end of the tube-pulling member 210 is located at the top end 111 of the through slot 110 and is lower than the upper end surface of the blanking plate 100. The test tube 2000 located on the blanking plate 100 is It can slide directly along the unloading plate 100, thereby realizing the unloading of the test tube 2000; when the tube pushing member 210 is in the second position, the upper end of the tube pushing member 210 passes through the through groove 110 and protrudes from the upper end surface of the unloading plate 100, and the upper end of the tube pushing member 210 can push the test tube 2000 adhered to the unloading plate 100, so that the test tube 2000 staying on the unloading plate 100 can slide down, reducing the possibility of the test tube 2000 staying on the unloading plate 100, and effectively ensuring the normal operation of the fully automatic sample processing system.

[0055] Since the fully automatic sample processing system adopts all the technical solutions of the unloading mechanism 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.
