[0027] like Figure 1 As shown, a slide rail shared drive transmission device is arranged on a base plate, comprising:

[0028] A first drive transmission mechanism is used to drive the aspiration and exhalation needle 1 to reciprocate and ascend. The first drive transmission mechanism includes a first slider 2 and a first drive mechanism, and the aspiration and exhalation needle 1 is mounted on the first slider 2.

[0029] A second drive transmission mechanism is used to drive the gripper 3 to reciprocate and lift; the second drive transmission mechanism includes a second slider 4 and a second drive mechanism, and the gripper 3 is mounted on the second slider 4;

[0030] The first slider 2 and the second slider 4 are arranged on the same slide rail 5 and are driven by the first driving mechanism and the second driving mechanism respectively to slide reciprocatingly up and down along the slide rail 5 to realize the reciprocating lifting and lowering movement of the aspiration needle 1 and the gripper 3.

[0031] Specifically, the aspiration needle is used to aspirate samples and / or reagents, and can be used to aspirate only samples or reagents, or can aspirate both samples and reagents.

[0032] Specifically, the first slider 2 is arranged at the upper part of the slide rail 5, the second slider 4 is arranged at the lower part of the slide rail 5, and the aspiration needle 1 is located directly above the gripper 3 and can pass through the gripper 3 to move back and forth, thereby ensuring that the aspiration needle 1 and the gripper 3 are coaxially arranged and do not affect each other. When the gripper 3 needs to grip the reaction container, the second driving mechanism drives the second slider 4 to move downward along the slide rail 5, thereby driving the gripper to move downward to grasp the reaction container. When it is necessary to aspirate the sample in the sample tube or the reagent in the reagent bottle, the first driving mechanism drives the first slider 2 to move downward along the slide rail 5, thereby driving the aspiration needle 1 to pass through the gripper 3 and move downward into the sample tube or reagent bottle to aspirate the sample or reagent. When it is necessary to add a sample to the reaction container, after the gripper 3 places the reaction container, the aspiration needle 1 can directly add the sample to the reaction container. When it is necessary to add a reagent to the reaction container, the aspiration needle 1 can directly add the reagent to the reaction container on the gripper, without the need for other adjustment movements to align the aspiration needle with the reaction container for adding samples or reagents, thereby saving time and increasing measurement speed.

[0033] Specifically, if Figure 1 As shown in , -3, the first driving mechanism includes a first synchronous belt 6, a first driving wheel 7, a first driven wheel 8 and a first driving source 9 that drives the first driving wheel 7 to rotate, which are arranged parallel to the slide rail 5. The first synchronous belt 6 is wound around the first driving wheel 7 and the first driven wheel 8, and the first slider 2 is fixedly connected to the first synchronous belt 6.

[0034] In order to save space in the width direction, the first synchronous belt 6 is wound around the slide rail 5. In order to save space occupied by the first drive source 9 in the length direction, the first driving wheel 7 is located on one side of the slide rail 5. The first driven wheels 8 include two wheels, which are respectively arranged at the upper and lower ends of the slide rail 5. The first synchronous belt 6 is wound around the first driving wheel 7 and the two first driven wheels 8 in sequence. The first driving mechanism also includes a pressure wheel 14 arranged between the first driving wheel and the first driven wheel, which is used to set the first synchronous belt 6 close to the slide rail 5 and parallel to it.

[0035] During operation, the first driving source 9 drives the first driving wheel 7 to rotate, and the first driving wheel 7 drives the corresponding first synchronous belt 6, two first driven wheels 8 and the pressure wheel to move. The linear motion of the first synchronous belt 6 drives the first slider 2 to move up and down along the slide rail 5 in a straight line, thereby realizing the linear lifting and lowering of the suction and exhalation needle 1 connected to the first slider 2 along the slide rail 5.

[0036] Specifically, if Figure 1-3 As shown, the second driving mechanism includes a second synchronous belt 10, a second driving wheel 11, a second driven wheel 12 and a second driving source 13 that drives the second driving wheel 11 to rotate, which are arranged parallel to the slide rail 5. The second synchronous belt 10 is wound around the second driving wheel 11 and the second driven wheel 12, and the second slider 4 is fixedly connected to the second synchronous belt 10.

[0037] During operation, the second driving source 13 drives the second driving wheel 11 to rotate, and the second driving wheel 11 drives the corresponding second driven wheel 12 to move. The linear motion of the second synchronous belt 10 drives the second slider 4 to move up and down along the slide rail 5 in a straight line, thereby realizing the linear lifting and lowering of the gripper 3 connected to the second slider 4 along the slide rail 5.

[0038] The utility model provides a slide rail shared drive transmission device, in which a first drive transmission mechanism for driving the reciprocating lifting and lowering motion of the suction and exhalation needle and a second drive mechanism for driving the gripper share a slide rail. This can reduce installation errors, eliminate the need to ensure the parallelism of the two slide rails, save space, and increase test speed.

[0039] In another embodiment, the present invention further provides an in vitro diagnostic analyzer, comprising the above-mentioned slide rail shared drive transmission device.
