[0036] Specifically, when the structure of the present invention is working, the test tube is transported from the outside to the test tube sliding guide cavity 2 of the test tube unloading and outlet member 200, and under the guiding output action of the test tube sliding guide cavity 2, the test tube is discharged from the vertical test tube discharge hole 1 and falls into the test tube labeling mechanism 300, and the first driving member 6 drives the taking-over assembly to take over the test tube and cooperates with the support frame 5 to support the test tube, and the second driving member 7 drives the clamping assembly to clamp and position the test tube, and then the label conveying module 4 transports the label to the labeling station of the labeling module 3 to label the test tube. Under the above setting, by setting The rationally designed test tube unloading and exporting member 200 and test tube labeling mechanism 300 realize fully automated processing of test tubes from unloading to labeling; the test tube unloading and exporting member 200 adopts a vertically arranged test tube discharge hole 1 and an internal test tube sliding guide cavity 2 to ensure that the test tubes can slide smoothly and accurately to the specified position; and the test tube labeling mechanism 300 realizes precise clamping and efficient labeling of the test tubes through the connecting pipe assembly, the clamping pipe assembly and the dual drive system; the test tube unloading and labeling device of this embodiment has a compact structure and is easy to operate, and can significantly improve the efficiency and accuracy of test tube processing, reducing manual participation and contamination risks.

[0037] In this embodiment, the lower end surface of the test tube sliding guide cavity 2 is provided with a guide slope 8. The guide slope 8 is arranged at an angle, and the lower end of the guide slope 8 is directed toward the test tube discharge hole 1. Specifically, under the above arrangement, the test tube can be conveniently slid from the guide slope 8 to the test tube discharge hole 1 for discharge into the pipe assembly in the labeling module 3. The support frame 5 supports the test tube, and the pipe clamping assembly clamps the test tube. The label conveying module 4 then conveys the label to the labeling station of the labeling module 3 for labeling.

[0038] Preferably, in this embodiment, the test tube discharge hole 1 is located in the middle of the lower end of the test tube discharge outlet 200 , and two guiding inclined surfaces 8 are provided, and the two guiding inclined surfaces 8 are respectively located on both sides of the test tube discharge hole 1 .

[0039] In this embodiment, the connecting pipe assembly includes a first transmission assembly, a movable swing arm 9 and a connecting pipe sleeve 10 installed at one end of the movable swing arm 9. The other end of the movable swing arm 9 is rotatably set on the support frame 5, and the first driving member 6 drives the movable swing arm 9 to rotate through the first transmission assembly; a test tube positioning groove 11 is provided through the middle of the connecting pipe sleeve 10; the test tube positioning groove 11 facilitates the positioning of the passing test tube and facilitates the guided falling of the test tube.

[0040] The tube clamping assembly includes a second transmission assembly, a labeling guide wheel 16, and a position-limiting clamping wheel 17. The labeling guide wheel 16 and the position-limiting clamping wheel 17 are each rotatably mounted on the support frame 5. The second driving member 7 drives the labeling guide wheel 16 to rotate via the second transmission assembly. A clamping space is formed between the labeling guide wheel 16 and the position-limiting clamping wheel 17. The support frame 5 has an opening 18 at the upper end of the clamping space. A support portion 19 for supporting the test tube is provided on the upper end surface of the support frame 5, located at the outer edge of the opening 18. The test tube discharge hole 1 is aligned with the opening 18 and is located directly above the opening 18.

[0041] Specifically, when the test tube falls from the test tube discharge hole 1, the falling direction of the test tube is aligned with the opening 18. Under the action of the pipe sleeve 10, the falling test tube is positioned by the pipe sleeve 10, and the support portion 19 of the support frame 5 located at the outer edge of the opening 18 is used to support the tube cap of the test tube to prevent the test tube from continuing to fall. Further, while supporting the test tube, the second driving member 7 drives the second transmission assembly to drive the labeling guide wheel 16 to rotate, and the clamping space formed between the limiting clamping wheel 17 of the clamping assembly and the labeling guide wheel 16 cooperates to clamp and limit the test tube to prevent the test tube from falling. The movable labeling guide wheel 16 guides the label sent by the label conveying module 4 and attaches it to the outer wall of the test tube. After the label is attached, the first driving member 6 drives the pipe sleeve 10 to swing through the first transmission assembly. The swing of the pipe sleeve 10 drives the test tube in the pipe sleeve 10 to break away from the clamping space. After breaking away, the test tube falls out of the pipe sleeve 10 under the action of its own weight, realizing the automation of the material receiving, labeling and unloading of the test tube. The structure is compact, and there is no need to transfer and carry the test tube multiple times, which reduces manual participation and can greatly reduce the contamination of the test tube due to human contact.

A synchronization block 15 is installed on one side of the movable swing arm 9. The synchronization block 15 is movably inserted into the synchronization groove 14. Specifically, under the above configuration, the first drive member 6 is a motor that drives the drive gear 12 to rotate, which in turn drives the sector gear 13 to rotate. The sector gear 13 and the movable swing arm 9 are connected through the synchronization groove 14 and the synchronization block 15. When the sector gear 13 rotates, the movable swing arm 9 is driven to swing, thereby driving the pipe sleeve 10 to swing, thereby facilitating the pipe sleeve 10 to drive the test tube out of the clamping space.

[0043] In this embodiment, the second transmission assembly includes a first synchronous wheel 20, a second synchronous wheel 21, and a synchronous belt 22. The output end of the second driving member 7 is drivingly connected to the first synchronous wheel 20. The labeling guide wheel 16 is coaxially connected to the second synchronous wheel 21. The synchronous belt 22 is wound around the first synchronous wheel 20 and the second synchronous wheel 21. Specifically, under the above arrangement, the second driving member 7 drives the first synchronous wheel 20 to rotate, and under the action of the synchronous belt 22, the second synchronous wheel 21 and the labeling guide wheel 16 are driven to rotate synchronously.

[0044] In this embodiment, the second transmission assembly further includes a tensioning pulley 23, which is in sliding contact with the synchronous belt 22. Specifically, this arrangement facilitates tensioning of the synchronous belt 22, ensuring stable rotation of the labeling synchronous wheel and, consequently, ensuring effective labeling. Furthermore, the support frame 5 is rotatably provided with a connecting shaft 24, the outer periphery of which is rotatably provided with a plurality of position-limiting clamping wheels 17. Specifically, the position-limiting clamping wheels 17 cooperate with the labeling guide wheel 16 to position the test tube.

The upper support 31 is connected to the lower support 32 via the plurality of connecting rods. The first driving member 6 and the second driving member 7 are respectively mounted between the upper support 31 and the lower support 32, and the first driving member 6 and the second driving member 7 are arranged in a stacked manner. Specifically, this arrangement can reduce the increase in structural area caused by arranging the first driving member 6 and the second driving member 7 on the same plane, thereby making the present invention compact.

[0046] In this embodiment, the first transmission assembly is located on the upper end surface of the upper bracket 31, the first driving member 6 is located above the second driving member 7, and the second transmission assembly is located on the lower end surface of the lower bracket 32. Specifically, under the above arrangement, a reasonable structural distribution of the first and second transmission assemblies is achieved, which avoids structural complexity and makes the structure of the utility model compact. Specifically, the structures of the first and second transmission assemblies do not interfere with each other, and the operation stability is high.

[0047] In this embodiment, a sensor 26 is further provided on one side of the clamping space. The sensor 26 can be installed in the support frame 5.

Specifically, during operation, when the sensor 26 senses that there is a test tube in the clamping space, that is, when a label needs to be attached, the horizontal driving member can drive the translation base 25 to approach the test tube labeling mechanism 300, and the label roll is arranged on the paper output shaft, and the label body is peeled off by the peeling component 29, and then the waste paper part of the label paper is recovered through the paper receiving shaft; wherein, when the horizontal driving member drives the translation base 25 to approach the test tube labeling mechanism 300, the peeling component 29 is located on one side of the labeling guide wheel 16, and the label paper at the peeling component 29 slides against the outer wall of the labeling guide wheel 16, and the peeling component 29 attaches the peeled label to the outer wall of the test tube via the labeling guide wheel 16.
