[0035] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0036] Please combine Figures 1 to 5 The sample rack unloading mechanism provided by the utility model is now described, and the sample rack unloading mechanism is used in an in vitro diagnostic device.

[0038] It can be understood that the driving motor 21 of the sample rack unloading mechanism is connected to the transmission member 22, the frame 1 is provided with a limiting groove 11, the transmission shaft 23 is connected to the unloading component 3 and is arranged in the limiting groove 11, the driving motor 21 drives the transmission member 22 to swing, the transmission member 22 is movably connected to the transmission shaft 23, and is used to drive the transmission shaft 23 to swing, the groove wall of the limiting groove 11 is used to guide the transmission shaft 23 to move along a preset trajectory, so that the transmission shaft 23 drives the unloading component 3 to move according to the preset trajectory, and the unloading component 3 can push out the sample rack 100, and by setting the driving mode of the transmission member 22 and the transmission shaft 23, the transmission shaft 23 can simultaneously drive the unloading component 3 to move, and the space occupied by the transmission member 22 and the transmission shaft 23 is relatively small, which can save space compared with the driving mode of the synchronous belt and synchronous wheel in the prior art, thereby facilitating the layout of the whole machine.

[0039] Furthermore, the transmission member 22 is provided with a transmission groove 221, and the transmission shaft 23 is arranged in the transmission groove 221. By providing the transmission groove 221, when the transmission member 22 drives the transmission shaft 23 to swing, the transmission shaft 23 can move in the transmission groove 221 according to the movement trajectory of the transmission shaft 23, thereby avoiding interference between the transmission shaft 23 and the transmission member 22, so that the transmission shaft 23 can swing smoothly.

[0040] Furthermore, the driving assembly 2 further includes a rolling member 24, which is rotatably connected to the transmission shaft 23 and is disposed in the transmission groove 221. By arranging the rolling member 24, the rolling member 24 and the transmission groove 221 are in rolling friction, which can reduce the friction between the transmission shaft 23 and the groove wall of the transmission groove 221, thereby facilitating the movement of the transmission shaft 23.

[0041] In one embodiment, if Figure 2 and Figure 3 As shown, the unloading assembly 3 includes a pushing member 31, a first rotating member 32 and a second rotating member 33.

[0043] In this embodiment, the limiting groove 11 is arc-shaped. Since the first rotating member 32 and the second rotating member 33 rotate around the first rotating end 321 and the second rotating end 331 respectively, the limiting groove 11 is set to an arc shape, so that the transmission shaft 23 can drive the first rotating member 32 and the second rotating member 33 to rotate.

[0044] Furthermore, the push member 31 is provided with a slide groove 311, and the unloading assembly 3 further includes a first connecting member 34, which is rotatably connected to the first movable end 322 and slidably disposed in the slide groove 311. Since the first rotating member 32 rotates with the first rotating end 321 as the center of the circle, the first movable end 322 is displaced, and by arranging the first connecting member 34 to be rotatably connected to the first movable end 322 and slidably disposed in the slide groove 311, the first movable end 322 can drive the first connecting member 34 to move in the slide groove 311, so that the first movable end 322 can be slidably connected to the push member 31.

[0045] Furthermore, the unloading assembly 3 further comprises a second connecting member 35, a slider 36 and a guide rail 37, wherein the guide rail 37 is mounted on the frame 1, the slider 36 is slidably connected to the guide rail 37, and the second connecting member 35 is mounted on the slider 36 and is rotatably connected to the second movable end 332. Since the second rotating member 33 rotates with the second rotating end 331 as the center, the second movable end 332 is displaced, and by arranging the second connecting member 35 to be mounted on the slider 36, the slider 36 and the guide rail 37 are slidably connected, and the second movable end 332 is rotatably connected to the second connecting member 35, so that the second movable end 332 can be slidably connected to the frame 1.

[0046] It should be noted that, since the first rotating end 321 is rotatably connected to the frame 1, the first movable end 322 is slidably connected to the pushing member 31, the second rotating end 331 is rotatably connected to the pushing member 31, and the second movable end 332 is slidably connected to the frame 1, the first rotating member 32 and the second rotating member 33 can be extended and retracted, thereby driving the pushing member 31 to move in a straight line.

[0047] In one embodiment, if Figure 3As shown, the sample rack unloading mechanism also includes a baffle 4 and an optical coupler 5. The baffle 4 is mounted on a slider 36. The optical coupler 5 is mounted on the frame 1 and is used to sense the baffle 4. The slider 36 drives the baffle 4 to move. When the optical coupler 5 detects the baffle 4, the pusher 31 pushes the sample rack 100 to complete, and the sample rack is in a retracted position.

In this way, the pushing member 31 can return to the initial state, thereby preventing the pushing member 31 from colliding with the sample rack 100 to be tested.

[0049] In one embodiment, if Figure 1 As shown, the sample rack unloading mechanism also includes a sample output plate 6, which is installed on the frame 1, and the driving component 2 can drive the unloading component 3 to push the sample rack 100 onto the sample output plate 6.
