[0032] See also Figure 1 and Figure 3 A transport device according to an embodiment includes a support member 100, a swing arm 200, a first driving mechanism 300 and a clamping mechanism 500. One end of the swing arm 200 is rotatably connected to the support member 100, and the other end is provided with a clamping mechanism 500. The clamping mechanism 500 is used to clamp the reaction cup. The first driving mechanism 300 is installed on the swing arm 200 and is used to drive the swing arm 200 to rotate relative to the support member 100. The first driving mechanism 300 includes a first driving member 310, a transmission assembly 320 and a transmission component 330. The transmission component 330 is fixed to the support member 100. The first driving member 310 is installed on the swing arm 200 and is transmission-connected to the transmission component 330 through the transmission assembly 320, so as to be able to drive the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100.

[0033] In this embodiment, the support member 100 passes through the swing arm 200, and the swing arm 200 is stacked on the transmission component 330 and is slidably connected to the transmission component 330. The transmission component 330 is fixed to the support member 100 so that the transmission assembly 320 can move circumferentially around the transmission component 330, thereby driving the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100, thereby transporting the reaction cup. During the transportation process, the support member 100 does not rotate, is not affected by torque, and is not easily damaged.

[0034] Furthermore, a bearing mounting member 210 is provided on the swing arm 200, and a first bearing 220 and a second bearing 230 are arranged at intervals along a straight line direction on the inner wall of the bearing mounting member 210. The support member 100 and the first bearing 220 and the second bearing 230 are plug-fitted together so as to be rotatably connected to the swing arm 200 and ensure the stability of rotation.

[0035] In one embodiment, see Figure 1 and Figure 3The transmission assembly 320 includes a first pulley 321 and a first transmission belt 322. The transmission component 330 is a second pulley and is sleeved on the support member 100. The first driving member 310 is connected to the first pulley 321 for driving and is used to drive the first pulley 321 to rotate. The first transmission belt 322 is wound between the first pulley 321 and the second pulley. The rotation of the first pulley 321 can drive the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100.

[0036] In this embodiment, the first driving member 310 and the first pulley 321 are respectively arranged on both sides of the swing arm 200, and the driving shaft of the first driving member 310 passes through the swing arm 200 and is in transmission connection with the first pulley 321. The second pulley is fixedly arranged on the support member 100, and the swing arm 200 is stacked on the second pulley and is in sliding connection with the second pulley. The first pulley 321 can rotate under the drive of the first driving member 310, while the second pulley does not rotate, so that the first pulley 321 can make a circular motion around the second pulley under the drive of the first transmission belt 322, thereby driving the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100. Specifically, the first driving member 310 can be a stepping motor.

[0037] In one embodiment, see Figure 1 and Figure 3 , the diameter of the first pulley 321 is smaller than the diameter of the second pulley. In this embodiment, the diameter of the first pulley 321 is smaller than the diameter of the second pulley so as to reduce the rotation speed of the swing arm 200, making it easier to control and reducing the risk of collision. The first pulley 321 is detachably connected to the first driving member 310 so as to achieve different transmission ratios by replacing the first pulley 321 with different diameters.

[0038] In one embodiment, see Figure 1 and Figure 3 The transmission component 320 is the first gear, the transmission component 330 is the second gear, and is sleeved on the support member 100. The first driving member 310 is connected to the first gear and is used to drive the first gear to rotate. The first gear is meshed with the second gear. The rotation of the first gear can drive the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100.

[0039] In this embodiment, the second gear is fixed to the support member 100, and the swing arm 200 is stacked on the second gear and slidably connected to the second gear. The first gear is meshed with the second gear and can rotate under the drive of the first driving member 310, while the second gear does not rotate, so that the first gear can make a circular motion around the second gear, thereby driving the swing arm 200 and the clamping mechanism 500 to rotate relative to the support member 100. Setting the transmission component 320 as the first gear and the transmission component 330 as the second gear can simplify the transmission structure, ensure transmission efficiency, and avoid elastic sliding and slipping that may occur in belt transmission.

[0040] In one embodiment, see Figure 1 and Figure 3 , the support member 100 extends in the vertical direction, and the transport device also includes a second driving mechanism 400, which includes a frame 410, a second driving member 420, a third pulley 430, a fourth pulley 440 and a second transmission belt 450. The third pulley 430 and the fourth pulley 440 are arranged on the frame 410 at intervals in the vertical direction, and are both rotatably connected to the frame 410. The second transmission belt 450 is wound between the third pulley 430 and the fourth pulley 440 and is connected to the support member 100. The second driving member 420 is connected to one of the third pulley 430 and the fourth pulley 440, and is used to drive the third pulley 430 and the fourth pulley 440 to rotate. The rotation of one of the third pulley 430 and the fourth pulley 440 can drive the second transmission belt 450 and the support member 100 to move in the vertical direction.

[0041] In this embodiment, the second driving mechanism 400 is used to drive the support member 100 to move in the vertical direction, thereby driving the swing arm 200 and the clamping mechanism 500 to move in the vertical direction, so as to facilitate the transportation of the reaction cup. The third pulley 430 and the fourth pulley 440 are arranged on one side of the frame 410, and the second driving member 420 is relatively arranged on the other side of the frame 410. The driving shaft of the second driving member 420 passes through the frame 410 and is connected to one of the third pulley 430 and the fourth pulley 440. Specifically, the fourth pulley 440 is arranged below the third pulley 430, and the second driving member 420 is connected to the fourth pulley 440, so as to lower the center of gravity of the transport device and prevent the transport device from tipping over. The second driving member 420 can be optionally a stepping motor.

[0042] The third frame 410 is provided with a guide member 411 , in which a guide groove extending in the vertical direction is provided. The support member 100 passes through the frame 410 and is slidably connected with the groove wall of the guide groove, thereby ensuring the stability and accuracy of the movement of the support member 100 .

[0043] In one embodiment, see Figure 1 and Figure 3The second driving mechanism 400 also includes a connecting member 460, a first guide rail 470 and a first slider 480. The first guide rail 470 is installed on the frame 410 and extends in the vertical direction. The first slider 480 is slidably arranged on the guide rail. The connecting member 460 is installed on the support member 100 and is connected to the first slider 480 and the second transmission belt 450.

[0044] In this embodiment, the connecting member 460 is used to clamp and fix the support member 100, and the connecting member 460 is connected to the first slider 480 and the second transmission belt 450 to drive the support member 100 to move in the vertical direction. The first guide rail 470 and the first slider 480 are used to ensure the stability and accuracy of the movement of the support member 100.

[0045] In one embodiment, see Figure 1 and Figure 3 The support member 100 extends in the vertical direction and forms a rack structure. The transport device also includes a second driving mechanism 400. The second driving mechanism 400 includes a frame 410, a second driving member 420 and a third gear. The second driving member 420 is connected to the third gear and is used to drive the third gear to rotate. The third gear is meshed with the rack structure of the support member 100. The rotation of the third gear can drive the support member 100 to move in the vertical direction.

[0046] In this embodiment, the second driving mechanism 400 is used to drive the support member 100 to move in the vertical direction, thereby driving the swing arm 200 and the clamping mechanism 500 to move in the vertical direction to facilitate the transportation of the reaction cup. The gear rack transmission of the third gear and rack structure drives the support member 100 to move, which can ensure the transmission efficiency and avoid elastic sliding and slipping that may occur in belt transmission.

[0047] In one embodiment, see Figures 1 to 3 The support member 100 is tubular, and a wire groove 110 is provided in the support member 100 . The wire groove 110 extends along the extension direction of the support member 100 and passes through the support member 100 . The wire groove 110 is used to guide the wire to the first driving mechanism 300 and the clamping mechanism 500 .

[0048] In this embodiment, the size of the support member 100 can be customized according to actual needs without being restricted by standard parts, so that the overall structure of the handling device is simple and compact. Replacing the spline shaft with the tubular support member 100 can simplify the transmission structure and reduce costs. The wire groove 110 can guide the wire to the first drive member 310 of the first drive mechanism 300 and the third drive member 520 of the clamping mechanism 500, so that the overall structure of the handling device is simple and compact. Furthermore, the provision of the wire groove 110 can also reduce the weight of the handling device.

[0049] In one embodiment, see Figures 1 to 4The clamping mechanism 500 includes a clamping jaw mounting member 510, a third driving member 520, a driving wheel 530, a first clamping assembly 540, a second clamping assembly 550 and a first elastic member 560. The clamping jaw mounting member 510 is mounted on the swing arm 200. The first clamping assembly 540 and the second clamping assembly 550 are both rotatably connected to the clamping jaw mounting member 510. The third driving member 520 is mounted on the clamping jaw mounting member 510 and is transmission-connected to the driving wheel 530 so as to be able to drive the driving wheel 530 to rotate. Two abutment protrusions 531 are arranged on the driving wheel 530 in opposition to each other. The rotation of the driving wheel 530 can make the two abutment protrusions 531 abut against the first clamping component 540 and the second clamping component 550 respectively, thereby driving the first clamping component 540 and the second clamping component 550 to move relatively away from each other. The first elastic member 560 elastically connects the first clamping component 540 and the second clamping component 550 to be able to drive the first clamping component 540 and the second clamping component 550 to move relatively close to each other, thereby clamping the reaction cup.

[0050] In this embodiment, the first clamping assembly 540 includes a first clamping arm 541 and a first clamping portion 542, and the two ends of the first clamping arm 541 are rotatably connected to the clamping jaw mounting member 510 and the first clamping portion 542 respectively. The second clamping assembly 550 includes a second clamping arm 551 and a second clamping portion 552, and the two ends of the second clamping arm 551 are rotatably connected to the clamping jaw mounting member 510 and the second clamping portion 552 respectively. The first elastic member 560 elastically connects the first clamping portion 542 and the second clamping portion 552 so that the first clamping portion 542 and the second clamping portion 552 abut against each other. Specifically, two first clamping arms 541 are provided, and the two first clamping arms 541 are arranged parallel to each other, and two second clamping arms 551 are provided, and the two second clamping arms 551 are arranged parallel to each other.

[0051] The rotation of the driving wheel 530 can make the two abutting protrusions 531 abut against the first clamping arm 541 and the second clamping arm 551, thereby driving the first clamping portion 542 and the second clamping portion 552 to move relatively away from each other, so that the reaction cup can be placed between the first clamping portion 542 and the second clamping portion 552. The rotation of the driving wheel 530 can also make the abutting protrusion 531 leave the first clamping arm 541 and the second clamping arm 551, and the first elastic member 560 pulls the first clamping portion 542 and the second clamping portion 552 closer to each other, so as to clamp the reaction cup.

[0052] In this embodiment, the clamping mechanism 500 further includes a buffer assembly 570, which includes a buffer mounting member 571, a second guide rail 572, a second slider 573 and a second elastic member 574. The buffer mounting member 571 is mounted on the swing arm 200, the second guide rail 572 is mounted on the buffer mounting member 571 and extends in the vertical direction, the second slider 573 is slidably arranged on the second guide rail 572 and connected to the clamping jaw mounting member 510, so that the clamping jaw mounting member 510 can move in the vertical direction. The second elastic member 574 elastically connects the buffer mounting member 571 and the clamping jaw mounting member 510. When the clamping mechanism 500 moves in the vertical direction driven by the support member 100, if it collides with an external structure, the clamping jaw mounting member 510 can slide along the second guide rail 572 and be buffered by the second elastic member 574. After the external force is removed, the second elastic member 574 can pull the clamping jaw mounting member 510 to reset. Specifically, the first elastic member 560 and the second elastic member 574 may both be springs.

[0053] See also Figure 1 The utility model also provides a sample analyzer, which includes an analysis device and a transport device of any of the above embodiments. In this embodiment, the transport device can transport the reaction cup between multiple stations such as a sample adding station and a test station of the analysis device to perform sample analysis. During the transport process, the support member 100 does not rotate, is not affected by torque, and is not easily damaged.
