The unloading assembly 2 includes a mounting frame 21, a driving module 22, a guide member 23 and a push member 24. The mounting frame 21 is mounted on the frame body 11. The driving module 22 is mounted on the mounting frame 21. The push member 24 is slidably connected with the mounting frame 21. The push member 24 is provided with a guide groove 241. The guide member 23 is penetrated in the guide groove 241. The driving module 22 is used to drive the guide member 23 to move so as to abut and cooperate with the groove wall of the guide groove 241 through the guide member 23, and drive the push member 24 to move, so that the push member 24 unloads the test tube rack 100 from the sample outlet channel 111 to the support assembly 12.

[0036] It can be understood that the rack body 11 of the automatic unloading mechanism of the test tube rack 100 is provided with a sample outlet channel 111, and the test tube rack 100 can move from the sample outlet channel 111 to a position relative to the support assembly 12, the mounting frame 21 is installed on the rack body 11, the driving module 22 is installed on the mounting frame 21, the pushing member 24 is slidably connected with the mounting frame 21, the pushing member 24 is provided with a guide groove 241, and the guide member 23 is penetrated by the guide groove 241. The driving module 22 is used to drive the guide member 23 to move so as to abut and cooperate with the groove wall of the guide groove 241 through the guide member 23, so as to drive the pushing member 24 to move, so that the pushing member 24 unloads the test tube rack 100 from the sample outlet channel 111 to the support assembly 12, and by setting the transmission mode of the guide member 23 and the groove wall of the guide groove 241, the noise is small during the process of pushing out the test tube rack 100, and the test tube rack 100 can be pushed out in parallel and stably, so that it is not easy to tilt or jam the test tube rack 100.

The extending direction of the oblique groove is set at an angle with the first direction. Specifically, the guide groove 241 is an oblique groove, so that during the movement of the guide member 23 in the guide groove 241, after force analysis, there are two decomposed forces, which are the opposite direction force along the first direction and the opposite direction force along the second direction, thereby ensuring that the pusher 24 can make a linear motion driven by the guide member 23.

[0038] In some embodiments, the extending direction of the inclined slide groove is set at an angle of 30 degrees to 60 degrees with the first direction.

[0039] Furthermore, the guide member 23 drives the push member 24 to move along the second direction, and the first direction and the second direction are set at an angle. The push member 24 moves along the second direction, so that the push member 24 can push the test tube rack 100 horizontally and steadily, thereby ensuring that the test tube rack 100 will not tilt or get stuck.

[0040] It should be noted that, according to the placement position of the automatic unloading mechanism of the test tube rack 100, the automatic unloading mechanism of the test tube rack 100 can be placed horizontally or vertically.

The first guide rail 211 is slidably connected to the first guide block 242 and is used to guide the pusher 24 to move along the second direction. By providing the first guide rail 211, the pusher 24 can make a linear motion along the first guide rail 211, so that the pusher 24 can push the test tube rack 100 onto the support assembly 12.

[0042] In this embodiment, the mounting frame 21 includes a first mounting portion extending along a first direction, and a second mounting portion connected to the first mounting portion, the first mounting portion and the second mounting portion are arranged at an angle, the driving module 22 is installed on the first mounting portion, and the first guide rail 211 is installed on the second mounting portion. Specifically, the first mounting portion and the second mounting portion are arranged at an angle of 90 degrees, the driving module 22 is installed on the first mounting portion, and the first guide rail 211 is installed on the second mounting portion, so that this installation method can save the installation space of the unloading mechanism.

[0043] In one embodiment, continue as Figure 2 As shown, the unloading assembly 2 further includes a support member 25, which is connected to the push member 24 and is slidably connected to the mounting frame 21, and the support member 25 is used to support the push member 24. Specifically, the support member 25 can be a ball plunger. Since the push member 24 has a certain length in the first direction, in order for the push member 24 to maintain the horizontal pushing of the test tube rack 100, the support member 25 is provided so that the push member 24 can move horizontally smoothly.

[0044] In one embodiment, if Figure 2 and Figure 3As shown, the driving module 22 includes a driving motor 221, a first synchronous wheel 222, a second synchronous wheel 223 and a synchronous belt 224, and the unloading component 2 also includes a connecting module 26. The first synchronous wheel 222 is rotatably connected to the mounting frame 21, and the second synchronous wheel 223 is rotatably connected to the mounting frame 21.

The synchronous belt 224 is connected to the guide member 23 through the connecting module 26. The driving motor 221 is installed on the mounting frame 21 and is connected to the first synchronous wheel 222. The driving motor 221 can drive the first synchronous wheel 222 to drive the synchronous belt 224 to move, so that the guide member 23 can move along the first direction.

[0045] Specifically, the driving motor 221 drives the first synchronous wheel 222 to rotate, the first synchronous wheel 222 drives the synchronous belt 224 to move, the synchronous belt 224 drives the second synchronous wheel 223 to rotate, the synchronous belt 224 also drives the connecting module 26 to move, the connecting module 26 drives the guide member 23 to move, the guide member 23 moves in the guide groove 241, so that the guide member 23 can drive the pushing member 24 to move, thereby pushing the test tube rack 100 onto the support assembly 12.

[0046] In this embodiment, the connection module 26 includes a pressing piece 261, a fixing bracket 262 and a fixing shaft 263. The pressing piece 261 is connected to the synchronous belt 224 and is connected to the fixing shaft 263 through the fixing bracket 262.
