Therefore, the features defined with “first” and “second” can explicitly or implicitly include one or more of the features.

[0054] The utility model provides a kind of detection mechanism for sample delivery, it includes mounting, first position detection sensor and second position detection sensor;The first position detection sensor, the second position detection sensor is respectively arranged on the mounting, and the detection height of the second position detection sensor is higher than the detection height of the first position detection sensor, the first position detection sensor is used to detect material, and the second position detection sensor is used to detect the container contained on the material. The detection mechanism for sample delivery is provided with the first position detection sensor and the second position detection sensor, and the detection height of the second position detection sensor is higher than the first position detection sensor, so that two different height positions can be detected by two position detection sensors. When material is empty material (no container is contained on material), only the first position detection sensor can detect signal when material flows through the detection mechanism for sample delivery, and the second position detection sensor cannot detect signal;When container is contained on material, the first position detection sensor and the second position detection sensor can detect signal. The state of the current flowing material is detected, so as to facilitate subsequent material diversion and corresponding operation.

[0055] Please refer to Figures 1 to 9 In an embodiment, a detection mechanism 100 for sample delivery is provided, which is mainly used for detecting material and detecting the state of the current flowing material.

[0056] The detection mechanism 100 for sample feeding comprises a mounting member 10, a first position detection sensor 20 and a second position detection sensor 30, which are respectively arranged on the mounting member 10. The detection height of the second position detection sensor 30 is higher than that of the first position detection sensor 20, i.e. the detection areas of the second position detection sensor 30 and the first position detection sensor 20 are at different heights, so that components at different heights can be detected. The first position detection sensor 20 is used to detect the material, and the second position detection sensor 30 is used to detect the container contained on the material. That is, the second position detection sensor 30 is used to detect whether the container is contained on the material, and when the container is contained on the material and the container flows through the detection mechanism for sample feeding along with the material, the detection area of the second position detection sensor 30 corresponds to the container, so that the corresponding signal can be detected.

[0057] By arranging the first position detection sensor 20 and the second position detection sensor 30 at different heights, the state of the material flowing through the detection mechanism for sample feeding can be detected. When the container is not contained on the material flowing through, only the signal detected by the first position detection sensor 20 can be obtained; and when the container is contained on the material flowing through, the signals detected by the first position detection sensor 20 and the second position detection sensor 30 can be obtained. In this way, the state of the material flowing through can be detected, so as to facilitate the subsequent processing of the material (such as diversion, feeding, taking, etc.).

[0058] As Figure 7 and Figure 8As shown, specifically, in an embodiment, the material is a carrier 200 for loading the container, the carrier 200 is provided with a receiving hole 210, the carrier 200 can accommodate the container 300 for loading the sample to be analyzed through the receiving hole 210. After the container 300 is transported from the pipeline to the sample delivery device, it can be sent into the carrier 200 by the grabbing device (such as a mechanical hand), and then flow through the carrier 200 on the sample delivery device 100, so as to drive the container 300 to flow and transfer the container 300 to another pipeline. More specifically, after the container 300 is loaded into the carrier 200, the bottom of the container 300 is located in the receiving hole 210, and the top of the container 300 extends out of the carrier 200, that is, a part of the container 300 is located outside the carrier 200, so that when the carrier 200 loaded with the container 300 flows through the sample delivery device 100, the second position detection sensor 30 can correspondingly detect the corresponding signal. At the same time, a part of the container 300 is located outside the carrier 200, which can facilitate the grabbing device to take and place.

[0059] Preferably, in an embodiment, the first position detection sensor 20 is arranged obliquely. By arranging the first position detection sensor 20 obliquely, the first position detection sensor 20 can be better avoided from interfering with other components, which is conducive to the arrangement of the sample delivery detection mechanism 100 on the sample delivery device, and can also better detect the material flowing through the flow channel.

[0060] Preferably, in an embodiment, the mounting member 10 includes a base 11 and a fixing plate 12 arranged on the base 11, the fixing plate 12 includes a first connecting plate 121, a first mounting plate 122 and a second mounting plate 123. The first connecting plate 121 is connected with the base 11, the first mounting plate 122 is connected with the first connecting plate 121, and the second mounting plate 123 is connected with the first mounting plate 122. The first position detection sensor 20 is arranged on the first mounting plate 122, and the second position detection sensor 30 is arranged on the second mounting plate 123. Through this structure, the first position detection sensor 20 and the second position detection sensor 30 can be more stably arranged on the mounting member 10.

[0061] Preferably, in an embodiment, the first mounting plate 122 is obliquely arranged. By obliquely arranging the first mounting plate 122, the installation of the first position detection sensor 20 can be facilitated. In particular, when the first position detection sensor 20 needs to be obliquely arranged, by obliquely arranging the first mounting plate 122, the installation difficulty of the first position detection sensor 20 can be further reduced, and meanwhile the connection reliability between the first position detection sensor 20 and the first mounting plate 122 can be improved.

[0062] Preferably, in an embodiment, a first waist-shaped groove 1221 is formed on the first mounting plate 122, and the first position detection sensor 20 is arranged at the first waist-shaped groove 1221. By forming the first waist-shaped groove 1221, the installation of the first position detection sensor 20 can be facilitated, and meanwhile the position of the first position detection sensor 20 can be adjusted, so that the detection area of the first position detection sensor 20 after installation can correspond to the area through which the material flows. A second waist-shaped groove 1231 is formed on the second mounting plate 123, and the second position detection sensor 30 is arranged at the second waist-shaped groove 1231. Similarly, by forming the second waist-shaped groove 1231, the installation and adjustment of the second position detection sensor 30 can be facilitated, so that the detection area of the second position detection sensor 30 after installation can correspond to the area through which the container flows. Specifically, in an embodiment, the first waist-shaped groove 1221 and the second waist-shaped groove 1231 extend along the vertical direction, so that the height of the first position detection sensor 20 and the second position detection sensor 30 can be adjusted.

[0063] Preferably, in an embodiment, the first position detection sensor 20 and the second position detection sensor 30 are both proximity switches. That is, in this embodiment, both position detection sensors are non-contact sensors, so that the normal flow of the material can be avoided to be interfered. Meanwhile, the proximity switch also has good detection performance, and can accurately feedback the state of the material.

[0064] Meanwhile, in an embodiment, a conveying device 1000 for sample feeding is also provided, which comprises a conveying line 400, a barrier 500 arranged above the conveying line 400 and separating a first flow channel 501 above the conveying line 400, and the detection mechanism 100 for sample feeding. The arrangement of the barrier 500 can guide the materials conveyed on the conveying line 400, so as to orderly arrange and convey the materials. The first position detection sensor 20 and the second position detection sensor 30 are arranged above the conveying line 400, and the detection areas of the first position detection sensor 20 and the second position detection sensor 30 are directed towards the first flow channel 501, so as to detect the materials in the first flow channel 501. In this embodiment, the detection mechanism 100 for sample feeding is mainly used to detect whether the materials conveyed in the first flow channel 501 contain containers.

[0065] Preferably, in an embodiment, the barrier 500 also separates a second flow channel 502 above the conveying line 400. The barrier 500 separates the first flow channel 501 and the second flow channel 502 above the conveying line 400, so that the materials can be conveyed in two different flow channels, thereby improving the conveying efficiency. Moreover, the barrier 500 separates multiple flow channels, so that materials in different states can be conveyed in different flow channels, thereby avoiding the interference between materials in different states, and further improving the conveying efficiency.

[0066] More preferably, in an embodiment, a first gap 503 is arranged on the barrier 500 between the first flow channel 501 and the second flow channel 502, and the first gap 503 connects the first flow channel 501 and the second flow channel 502. The conveying device 1000 for sample feeding further comprises a material distribution plate 600, which is rotatably arranged at the first gap 503, and the material distribution plate 600 can be rotated into the first flow channel 501 to block the materials in the first flow channel 501, so as to make the materials flow into the second flow channel 502 through the first gap 503. That is, in this embodiment, the material distribution plate 600 can guide the materials to change lanes, for example, as shown in FIG. 6, when the material distribution plate 600 is rotated into the first flow channel 501, the materials in the first flow channel 501 are blocked, and the materials flow into the second flow channel 502 through the first gap 503. Figure 6As shown, at this time, the distribution plate 600 is located in the first flow channel 501, so when the material in the first flow channel 501 flows to the distribution plate 600, it will be blocked and guided by the distribution plate 600 to the first gap 503, and then flow into the second flow channel 502, thereby switching the flow channel of the material. When it is not necessary to guide the material in the first flow channel 501 to the second flow channel 502, the distribution plate 600 can be driven to rotate, so that the distribution plate 600 rotates out of the first flow channel 501, and the distribution plate 600 is flush with the blocking piece 500, so as not to affect the normal flow of the material in the first flow channel 501. The distribution plate 600 is located at the rear side of the sample feeding detection mechanism 100, wherein the rear side is referenced with the flow direction of the material on the conveying line 400. That is, when the material flows on the conveying line 400, it will first pass through the area where the sample feeding detection mechanism 100 is located, and then pass through the area where the distribution plate 600 is located. The distribution plate 600 is used to rotate according to the detection result of the sample feeding detection mechanism 100. That is, in this embodiment, the controller in the sample feeding conveying device 1000 controls the distribution plate 600 to rotate according to the detection result of the sample feeding detection mechanism 100, so as to realize the distribution of the material. For example, in an embodiment, when the sample feeding detection mechanism 100 detects that the carrier 200 is loaded with the container 300, the controller controls the distribution plate 600 to retract, so that the carrier 200 loaded with the container 300 continues to flow along the first flow channel 501; when the sample feeding detection mechanism 100 detects that the carrier 200 is not loaded with the container 300, the controller controls the distribution plate 600 to rotate into the first flow channel 501, so as to distribute the empty carrier 200 into the second flow channel 502 for feeding. Similarly, when the sample feeding detection mechanism 100 detects that the carrier 200 is loaded with the container 300, the distribution plate 600 rotates out; when the sample feeding detection mechanism 100 detects that the carrier 200 is not loaded with the container 300, the distribution plate 600 retracts. In this way, the empty carrier 200 can be distributed and conveyed, so as to further improve the efficiency of feeding and conveying.

[0067] Specifically, in an embodiment, the distribution plate 600 is rotatably arranged on a distribution plate support 610, and a driving support 620 is further connected to the top of the distribution plate 600. When it is needed to drive the distribution plate 600 to rotate, the driving support 620 is powered to drive the distribution plate 600 to rotate. The power source of the driving support 620 can be an electric motor, for example, the electric motor cooperates with a gear and rack structure to drive the driving support 620 to move, thereby driving the distribution plate 600 to rotate.

[0068] In addition, in other embodiments, other functional components can also be arranged in the sample feeding conveying device 1000, and the detection of the sample feeding detection mechanism 100 on the material can control the corresponding operation of the other functional components. For example, a material blocking mechanism can also be arranged in the sample feeding conveying device 1000, when the sample feeding detection mechanism 100 detects that the carrier 200 is loaded with the container 300, the controller controls the material blocking mechanism to extend to stop the carrier 200, thereby taking the material; or, when the sample feeding detection mechanism 100 detects that the carrier 200 is empty, the controller controls the material blocking mechanism to extend to stop the carrier 200, thereby loading the material.

[0069] Preferably, in an embodiment, the sample feeding conveying device 1000 further comprises a code scanning mechanism 700, which is arranged above the conveying line 400 and faces the conveying line 400 to scan the information code of the container on the material conveyed on the conveying line 400. It can be understood that each of the containers 300 is provided with an information code for marking the identity of the container 300, and the container 300 is identified by the code scanning mechanism 700, so that the container 300 can be conveyed according to the priority. For example, when the code scanning mechanism 700 scans the container 300 with the highest priority, a corresponding signal can be output to the controller, so that the controller controls the corresponding components in the sample feeding conveying device 1000 to operate. Specifically, the code scanning mechanism 700 can be located in front of the material blocking mechanism, and when the container 300 with the highest priority enters the sample feeding conveying device 1000, all the containers in front of the container 300 with the highest priority are released by the components in the sample feeding conveying device 1000, so that the other containers continue to circulate on the conveying line 400, and the material blocking mechanism does not block the material, and only blocks the material when the container 300 with the highest priority flows through the code scanning mechanism 700, so as to ensure that the container 300 with the highest priority can be taken out at the fastest time. Alternatively, the code scanning mechanism 700 can be located in front of the material distribution plate 600, and when the container 300 with the highest priority enters the sample feeding conveying device 1000, all the containers in front of the container 300 with the highest priority are released by the components in the sample feeding conveying device 1000, so that the other containers continue to circulate on the conveying line 400, and only when the container 300 with the highest priority flows through the code scanning mechanism 700, the material distribution plate 600 is controlled to turn into the first flow channel 501, so as to guide the container 300 with the highest priority into the second flow channel 502 for taking out. That is, the container 300 can be identified by the code scanning mechanism 700, and a corresponding detection signal can be output to the controller, and the components can be controlled by the controller, so as to improve the conveying efficiency of the specific container 300.

[0070] Specifically, in an embodiment, the information code on the container 300 is a two-dimensional code, and the code scanning mechanism 700 is a two-dimensional code scanner. More specifically, in an embodiment, the code scanning mechanism 700 is mounted on a support frame 800.

[0071] Meanwhile, in an embodiment, a sample delivery transfer device is also provided, which is applied with the sample delivery conveying device 1000. The sample delivery transfer device can also be provided with a receiving and sending device 2000 and a grabbing device 3000. The receiving and sending device 2000 is arranged at the inlet and outlet of the pipeline to receive or send the container. The receiving and sending device 2000 can refer to CN115448033A, which will not be described here. The grabbing device 3000 is mainly used to send the container 300 in the receiving and sending device 200 into the sample delivery conveying device 1000 or send the container 300 in the sample delivery conveying device 1000 into the receiving and sending device 2000. The grabbing device 3000 can be a mechanical hand.

[0072] In an embodiment, a code scanning mechanism can be arranged on the receiving and sending device 2000 or the grabbing device 3000, so as to scan the information code on the container 300 to determine whether there is a container 300 with high priority to flow in, so that the controller in the sample delivery conveying device 1000 controls the corresponding components to operate.

[0073] The sample delivery transfer device is connected with each point through a pipeline. The container sent by each point is first sent into the sample delivery transfer device through the pipeline, and then is sent to the receiving point through another pipeline after being distributed by the sample delivery transfer device. The arrangement of the sample delivery transfer device can reduce the pipelines required in the pneumatic sample delivery system and reduce unnecessary pipeline design and the number of receiving points.

[0074] The above is only an embodiment of the present application, and it should be pointed out that, for those skilled in the art, improvements can be made without departing from the inventive concept, but these all belong to the protection scope of the present application.
