[0051] Please refer to Figures 1 to 9 In one embodiment, a conveying device 100 for sample delivery is provided, which includes a conveying mechanism 10, a barrier 20 and a material shifting mechanism 30.

[0052] The conveying mechanism 10 includes a first conveying line 11 and a second conveying line 12 arranged side by side with the first conveying line 11, and the conveying direction of the second conveying line 12 is opposite to that of the first conveying line 11, for example, Figure 2In the shown embodiment, the conveying direction of the first conveying line 11 is towards the upper left, and the conveying direction of the second conveying line 12 is towards the lower right.

[0053] The barrier 20 is located above the conveying mechanism 10, and divides the first circulating flow channel 21 and the second circulating flow channel 22 on the first conveying line 11 and the second conveying line 12. That is, the first circulating flow channel 21 is partially located on the first conveying line 11 and partially located on the second conveying line 12; similarly, the second circulating flow channel 22 is partially located on the first conveying line 11 and partially located on the second conveying line 12. Through the arrangement of the barrier 20, the materials conveyed on the first conveying line 11 and the second conveying line 12 can be guided, so that the materials are orderly arranged and conveyed. And through the barrier 20, the first circulating flow channel 21 and the second circulating flow channel 22 are divided above the conveying mechanism 10, so that the materials can be conveyed separately in two different flow channels, thereby improving the conveying efficiency.

[0054] The material pushing mechanism 30 includes a first material pushing mechanism 31 and a second material pushing mechanism 32. The two ends of the first circulating flow channel 21 are respectively provided with the first material pushing mechanism 31, that is, the first material pushing mechanism 31 is provided at least twice. One of the first material pushing mechanisms 31 is used to transfer the materials in the first circulating flow channel 21 from the first conveying line 11 to the second conveying line 12, and the other first material pushing mechanism 31 is used to transfer the materials in the first circulating flow channel 21 from the second conveying line 12 to the first conveying line 11, so that the materials circulate in the first circulating flow channel 21. For example, as shown in the figure, when the materials in the first circulating flow channel 21 on the first conveying line 11 flow to the end, the materials are pushed by the first material pushing mechanism 31, so that the materials are transferred from the first conveying line 11 to the second conveying line 12, and the materials continue to flow along the first circulating flow channel 21 on the second conveying line 12; and as shown in the figure, when the materials in the first circulating flow channel 21 on the second conveying line 12 flow to the end, the materials are pushed by the other first material pushing mechanism 31, so that the materials are transferred from the second conveying line 12 to the first conveying line 11, and the materials flow back to the first circulating flow channel 21 on the first conveying line 11, so that the materials reciprocating circulate on the first conveying line 11 and the second conveying line 12. Figure 2 Figure 3 In the shown embodiment, when the materials in the first circulating flow channel 21 on the first conveying line 11 flow to the end, the materials are pushed by the first material pushing mechanism 31, so that the materials are transferred from the first conveying line 11 to the second conveying line 12, and the materials continue to flow along the first circulating flow channel 21 on the second conveying line 12; and as shown in the figure, when the materials in the first circulating flow channel 21 on the second conveying line 12 flow to the end, the materials are pushed by the other first material pushing mechanism 31, so that the materials are transferred from the second conveying line 12 to the first conveying line 11, and the materials flow back to the first circulating flow channel 21 on the first conveying line 11, so that the materials reciprocating circulate on the first conveying line 11 and the second conveying line 12.

[0055] ​The second circulation flow channel 22 is provided with the second material pushing mechanism 32 at both ends, that is, the second material pushing mechanism 32 is also provided with at least two. One of the second material pushing mechanism 32 is used to transfer the material in the second circulation flow channel 22 from the first conveying line 11 to the second conveying line 12, and the other of the second material pushing mechanism 32 is used to transfer the material in the second circulation flow channel 22 from the second conveying line 12 to the first conveying line 11. Similarly, when the material in the second circulation flow channel 22 located on the first conveying line 11 flows to the end, it will be transferred to the second conveying line 12 by one of the second material pushing mechanism 32; when the material in the second circulation flow channel 22 located on the second conveying line 12 flows to the end, it will be transferred to the first conveying line 11 by the other of the second material pushing mechanism 32, so that the material can flow reciprocatingly on the first conveying line 11 and the second conveying line 12.

[0056] The conveying device 100 for sample delivery can convey the material in two directions through the first conveying line 11 and the second conveying line 12, and can transfer the material through the first material pushing mechanism 31 and the second material pushing mechanism 32, so that the material can flow reciprocatingly on the first conveying line 11 and the second conveying line 12, thereby continuously circulating to receive the conveying container, conveying the container to any point, meeting the conveying demand. And the blocking piece 20 forms independent flow channels above the conveying mechanism 10, so that the material can be conveyed synchronously through multiple flow channels, and the material can be conveyed in a partitioned manner, which can better improve the conveying efficiency, and the blocking piece 20 can also guide the material to be arranged in order on the conveying mechanism 10, facilitating the receiving of the container.

[0057] Specifically, in an embodiment, the material is a carrier 200 for loading the container, and the carrier 200 is provided with a receiving hole 210, and the carrier 200 can accommodate the container for loading the sample to be analyzed through the receiving hole 210. After the container is conveyed from the pipeline to the sample delivery transfer device, it can be sent into the carrier 200 by a grabbing device (such as a mechanical hand), and flows on the conveying device 100 for sample delivery, thereby driving the container to flow and transferring the container to another pipeline. More specifically, after the container is loaded into the carrier 200, the bottom of the container is located in the receiving hole 210, and the top of the container extends out of the carrier 200, that is, a part of the container is located outside the carrier 200, thereby facilitating the grabbing device to take and place.

[0058] Specifically, in an embodiment, the first circulation flow channel 21 and the second circulation flow channel 22 are arranged side by side and adjacent to each other, the first circulation flow channel 21 is located at the inner side, and the second circulation flow channel 22 is located at the outer side.

[0059] Preferably, in an embodiment, the first pushing mechanism 31 comprises a first driving motor 311 and a rotating disc 312, the rotating disc 312 is arranged on the output shaft of the first driving motor 311, and the outer periphery of the rotating disc 312 is recessed to form a pushing cavity 3121 for accommodating materials. That is, in this embodiment, the first pushing mechanism 31 itself can provide power to move the materials, instead of relying entirely on the inertia of the materials transmitted on the conveying line. When the materials flow to the first pushing mechanism 31, they will flow into the pushing cavity 3121, and the rotating disc 312 will be driven to rotate by the first driving motor 311, so that the rotating disc 312 will rotate with the materials, thereby transferring the materials from one conveying line to another conveying line.

[0060] Specifically, in an embodiment, the outer periphery of the carrier 200 is provided with an annular groove 220, and the pushing cavity 3121 is an annular cavity. When the carrier 200 flows into the pushing cavity 3121, the rotating disc 312 will be correspondingly clamped into the annular groove 220, so that the carrier 200 can be more stably transferred and conveyed.

[0061] Preferably, in an embodiment, a plurality of pushing cavities 3121 are sequentially and spaced apart along the circumference of the rotating disc 312, so as to further improve the transfer efficiency.

[0062] Preferably, in an embodiment, the first pushing mechanism 31 further comprises an arc-shaped baffle 313, which is located outside the rotating disc 312 and spaced apart from the rotating disc 312. When the rotating disc 312 transfers the materials, the arc-shaped baffle 313 can block and limit the materials from the outside, so as to prevent the materials from falling out of the rotating disc 312, thereby improving the reliability of the first pushing mechanism 31 in transferring the materials.

[0063] Specifically, in an embodiment, the first driving motor 311 is a servo motor.

[0064] Specifically, in an embodiment, in order to avoid interference between the first conveying line 11 and the second conveying line 12, the first conveying line 11 and the second conveying line 12 can be arranged side by side and spaced apart. A support plate 13 can be arranged below the first pushing mechanism 31 and the second pushing mechanism 32, so as to support the materials when the first pushing mechanism 31 and the second pushing mechanism 32 transfer the materials, thereby preventing the materials from falling.

[0065] Preferably, in an embodiment, the second pushing mechanism 32 comprises a second driving motor 321, a driving wheel 322, a driven wheel assembly 323, a transmission belt 324 and a pushing rod 325. The driving wheel 322 is arranged on the output shaft of the second driving motor 321, the driven wheel assembly 323 is arranged opposite to the driving wheel 322, and the transmission belt 324 is arranged around the driving wheel 322 and the driven wheel 3231 of the driven wheel assembly 323. The pushing rod 325 is arranged on the transmission belt 324 to push the material to move. That is, in this embodiment, the second pushing mechanism 32 itself can provide power to drive the material to move, instead of relying entirely on the inertia of the material transmitted on the conveying line. The second driving motor 321 drives the driving wheel 322 to rotate, thereby driving the transmission belt 324 to run, so as to drive the pushing rod 325 to move. When the material flows to the second pushing mechanism 32, the pushing rod 325 pushes the material, thereby transferring the material from one conveying line to another conveying line.

[0066] Specifically, in an embodiment, when the pushing rod 325 is in the area at the bottom of the transmission belt 324, the height of the pushing rod 325 is flush with the height of the annular groove 220 on the carrier 200, so that the pushing rod 325 can be pushed into the annular groove 220 to push the carrier 200. When the pushing rod 325 is in the area at the top of the transmission belt 324, the height of the pushing rod 325 is higher than the carrier 200, so that the pushing rod 325 does not interfere with the carrier 200 when moving back.

[0067] Specifically, in an embodiment, the second driving motor 321 is a servo motor.

[0068] Preferably, in an embodiment, the second pushing mechanism 32 further comprises a base 326, and the second driving motor 321 and the driven wheel assembly 323 are arranged on the base 326. The driven wheel assembly 323 further comprises a connecting shaft 3232 and a bearing 3233, the connecting shaft 3232 is connected with the driven wheel 3231, and the connecting shaft 3232 is installed on the base 326 through the bearing 3233. Through this structure, the driven wheel 3231 can be more stably supported, and wear between components can be better avoided.

[0069] Preferably, in an embodiment, a plurality of pushing rods 325 are arranged on the transmission belt 324, so as to further improve the transfer efficiency.

[0070] Preferably, in an embodiment, two parallel and spaced transmission belts 324 are provided, and the shifting rod 325 is connected to the two transmission belts 324 through a chain 327. Through this structure, the connection reliability between the shifting rod 325 and the transmission belts 324 can be improved.

[0071] Preferably, in an embodiment, the partition 20 further divides a third flow channel 23 from the second conveying line 12, and the third flow channel 23 is adjacent to the second circulating flow channel 22. A first gap 201 is formed on the partition 20 between the third flow channel 23 and the second circulating flow channel 22, and the first gap 201 connects the third flow channel 23 and the second circulating flow channel 22. The sample conveying device 100 further comprises a distribution plate 40, which is rotatably arranged at the first gap 201, and the distribution plate 40 can be rotated into the second circulating flow channel 22 to block the material in the second circulating flow channel 22, so that the material flows into the third flow channel 23 through the first gap 201. That is, in this embodiment, the material can be guided to switch the flow channel through the distribution plate 40, for example, as shown in the figure, at this time the distribution plate 40 is located in the second circulating flow channel 22, so that when the material in the second circulating flow channel 22 flows to the distribution plate 40, it will be blocked and guided by the distribution plate 40 to the first gap 201, and then flow into the third flow channel 23 through the first gap 201, so as to switch the flow channel of the material. When the material in the second circulating flow channel 22 does not need to be guided into the third flow channel 23, the distribution plate 40 can be rotated to rotate out of the second circulating flow channel 22, so that the distribution plate 40 is flush with the partition 20, so as not to affect the normal flow of the material in the second circulating flow channel 22. Figure 2

[0072] Preferably, in an embodiment, a second gap 202 is further formed on the partition 20 between the third flow channel 23 and the second circulating flow channel 22, and the second gap 202 connects the third flow channel 23 and the second circulating flow channel 22. A guide 50 is arranged in the third flow channel 23 corresponding to the second gap 202. Through the guide 50, the material in the third flow channel 23 can be blocked and guided to the second gap 202, and then flow into the second circulating flow channel 22 through the second gap 202, so as to guide and switch the material in the third flow channel 23 to the second circulating flow channel 22.

[0073] ​In one embodiment, the material in the third flow channel 23 does not participate in the circulation. The third flow channel 23 can be used to transport empty carriers 200, and the third flow channel 23 can be used as a feeding flow channel, so that each time the container is transported into the sample feeding conveying device 100 by the grabbing device, the empty carrier 200 can be correspondingly transported into the third flow channel 23.

[0074] Specifically, in one embodiment, a sensor can be further arranged in the sample feeding conveying device 100, which is used to detect the material and output a corresponding signal to the controller of the sample feeding conveying device 100 to control the rotation of the distribution plate 40.

[0075] More specifically, in one embodiment, the sensor is mainly used to detect whether the carrier 200 in the second circulation flow channel 22 is loaded with a container. When the sensor detects that the carrier 200 is an empty carrier (not loaded with a container), a corresponding signal is output to promote the rotation of the distribution plate 40 into the second circulation flow channel 22, so that the empty carrier 200 flows from the second circulation flow channel 22 into the third flow channel 23, to ensure that the carrier 200 loaded with a container is transported in the second circulation flow channel 22. Of course, in other embodiments, the sensor can also be used to detect other objects according to the needs, and the selection can be made according to the actual needs.

[0076] The specific structure of the sensor can adopt two position sensors, one of which is arranged below to detect the carrier 200, and the other of which is arranged above to detect the container. When both position sensors detect a signal, it means that the currently detected carrier 200 is loaded with a container, otherwise it is not. In this way, the rotation of the distribution plate 40 is controlled.

[0077] Specifically, in one embodiment, the distribution plate 40 can be rotatably arranged on the distribution plate support 60, and the top of the distribution plate 40 is further connected with a driving support 70. When it is necessary to drive the rotation of the distribution plate 40, the driving support 70 provides power to promote the rotation of the distribution plate 40. The power source of the driving support 70 can adopt a motor, for example, a motor cooperates with a gear and rack structure to drive the movement of the driving support 70, thereby promoting the rotation of the distribution plate 40.

[0078] Specifically, in one embodiment, the first conveying line 11 and the second conveying line 12 are both chain plate conveying lines.
