[0061] In the related art, the transmission device is applied to transfer the test tube carrier in the device or between devices. However, since the current transmission device occupies a large space in the vertical direction, it cannot be applied to the device with limited height space, resulting in the inability to realize the transfer function of the test tube carrier.

The positive direction of the first direction is forward, the positive direction of the second direction is left, and the positive direction of the third direction is upward.

[0064] Please refer to Figures 1 to 7In an embodiment of the utility model, this transmission device 100 includes taking mechanism 10 and horizontal moving mechanism 20, and taking mechanism 10 includes clamping module 11, and clamping module 11 includes two clamping pieces 1111 that are oppositely spaced in the first direction, and the two clamping pieces 1111 are enclosed to form the taking material space of the test tube carrier 200, and the two clamping pieces 1111 are set up along the first direction and can be opened and closed, for clamping or loosening the two sides of test tube carrier 200 in the first direction, and horizontal moving mechanism 20 is set up at the side of taking mechanism 10 and is set up along the first direction or the second direction transversely, and horizontal moving mechanism 20 is drivenly connected with taking mechanism 10, for driving taking mechanism 10 to move transversely along the length direction of horizontal moving mechanism 20.

[0065] Wherein, transmission device 100 includes taking mechanism 10 and horizontal moving mechanism 20 that are sequentially arranged along the direction parallel to the horizontal plane. Specifically, horizontal moving mechanism 20 can be but not limited to linear module and other linear driving mechanisms, for driving taking mechanism 10 to move along the horizontal direction. The two clamping pieces 1111 of taking mechanism 10 are set up along the first direction and can be opened and closed, so as to clamp or loosen the two sides of test tube carrier 200 in the first direction, thereby enabling taking mechanism 10 to be clamped and cooperated with the side of test tube carrier 200 by mechanical clamping.

[0067] It can be understood that, since the horizontal moving mechanism 20 and taking mechanism 10 of transmission device 100 in the technical scheme of the utility model are sequentially arranged along the direction parallel to the horizontal plane, and the clamping module 11 of taking mechanism 10 can clamp test tube carrier 200 from the side of test tube carrier 200 in the first direction, the transverse clamping and horizontal transfer of test tube carrier 200 can be realized, thereby realizing the flat layout of transmission device 100, reducing the occupied space of transmission device 100 in the vertical direction, and making it applicable to equipment with limited height space.

[0068] Please refer to Figures 1 to 5In the embodiment of the utility model, clamping module 11 includes first mounting base 112, clamping assembly 111 and first drive assembly 113, first mounting base 112 is located at the side of horizontal moving mechanism 20, and is drivenly connected with horizontal moving mechanism 20;Clamping assembly 111 includes two clamping pieces 1111 movably arranged in first mounting base 112, and the two clamping pieces 1111 are used to be separately arranged on the opposite sides of test tube carrier 200 in the first direction;First drive assembly 113 is arranged in first mounting base 112, and is drivingly connected with clamping assembly 111, for driving one clamping piece 1111 to move relative to the other clamping piece 1111 along the first direction, so that the two clamping pieces 1111 are opened and closed to clamp or release test tube carrier 200.

[0069] Among them, first mounting base 112 is the installation base of clamping module 11, for installing clamping assembly 111 and first drive assembly 113.When horizontal moving mechanism 20 drives first mounting base 112 to move horizontally along the length direction, first mounting base 112 can drive first drive assembly 113 and clamping assembly 111 to move synchronously, thereby realizing the function of horizontally moving test tube carrier 200 clamped by clamping assembly 111.

[0070] In a feasible embodiment, first drive assembly 113 can only drive one clamping piece 1111 of clamping assembly 111 to move horizontally, and the position of the other clamping piece 1111 can remain unchanged, at this time, by moving one clamping piece 1111 towards the other clamping piece 1111, the distance between the two clamping pieces 1111 can be reduced to clamp test tube carrier 200;By moving one clamping piece 1111 away from the other clamping piece 1111, the distance between the two clamping pieces 1111 can be increased to release test tube carrier 200.

[0071] Of course, the technical scheme of the utility model is not limited to this, in some embodiments, the two clamping pieces 1111 can also move synchronously, to clamp test tube carrier 200 by moving towards each other, or release test tube carrier 200 by moving away from each other. The specific implementation can be set according to actual needs, which is not limited here.

[0072] Please refer to Figure 2 And Figure 3 In the embodiment of the utility model, clamping piece 1111 includes connecting part 1111a and clamping part 1111b, connecting part 1111a is movably arranged in first mounting base 112, at least one connecting part 1111a is drivingly connected with first drive assembly 113, to reciprocate along the first direction under the driving of first drive assembly 113;One end of clamping part 1111b is connected with connecting part 1111a, and the other end protrudes towards the side of mounting base along the second direction, and the clamping parts 1111b of the two clamping pieces 1111 are relatively spaced apart along the first direction.

[0073] Wherein, by movably setting the connecting part 1111a of the clamping piece 1111 on the first mounting base 112, and movably setting the first driving assembly 113 to drive the connecting part 1111a of one clamping piece 1111 to move along the first direction, the connecting part 1111a can drive the clamping part 1111b of the same clamping piece 1111 to move horizontally along the first direction, so that the clamping part 1111b of the clamping piece 1111 can be close to and abut against the side of the test tube carrier 200, so that the test tube carrier 200 can be clamped in the material taking space enclosed by the two clamping pieces 1111, or the clamping part 1111b of the clamping piece 1111 can be away from and release the side of the test tube carrier 200, so that the test tube carrier 200 can be released in the material taking space enclosed by the two clamping pieces 1111.

[0074] Specifically, the clamping part 1111b of the two clamping pieces 1111 can be provided as an arm structure, which can be shaped to the side structure of the test tube carrier 200, for example, in a feasible embodiment, the side of the test tube carrier 200 is provided with a groove, at this time, the shape of the arm structure in the clamping piece 1111 can be matched with the shape of the groove, so that the clamping piece 1111 can be limited to cooperate with the side of the test tube carrier 200, which is beneficial to the clamping assembly 111 to stably clamp the test tube carrier 200, so as to protect the test tube carrier 200 from falling due to abnormal conditions during transportation, thereby avoiding the samples in the test tubes carried in the test tube carrier 200 from being damaged.

[0075] Specifically, in the embodiment, the test tube carrier 200 can include a plurality of frame bodies stacked in the third direction, and at least part of the circumferential parts of adjacent two frame bodies can be spaced apart to form a groove between the circumferential parts of the adjacent two frame bodies. At this time, when the clamping assembly 111 clamps the test tube carrier 200, the arm structure in the clamping piece 1111 can enter the groove and be clamped between the adjacent two frame bodies. In this way, on the one hand, the clamping piece 1111 can be closely matched with the side of the test tube carrier 200, and the test tube carrier 200 can be stably clamped by the clamping force of the test tube carrier 200 in the first direction, on the other hand, the clamping piece 1111 can also support the test tube carrier 200 in the third direction through the arm structure clamped in the groove, thereby effectively reducing the risk that the test tube carrier 200 will fall due to abnormal conditions during transportation. Optionally, in some embodiments, the clamping piece 1111 is in the shape of "L", and the clamping part 1111b is one side of the "L" shape. When the clamping piece 1111 clamps the test tube carrier 200, the clamping part 1111b is clamped in the groove, which helps to fix the test tube carrier 200.

[0076] Please refer to Figure 5In some embodiments, the clamping assembly 111 can further be provided with a buffer 111a, which can serve as a buffer when the clamping assembly 111 clamps the test tube carrier 200, so as to reduce the risk of damage caused by collision between the clamping assembly 111 and the test tube carrier 200. Moreover, by providing the buffer 111a on the clamping assembly 111, the friction between the clamping assembly 111 and the test tube carrier 200 can be increased, so as to further ensure the clamping stability of the clamping assembly 111 to the test tube carrier 200.

[0077] Specifically in the present embodiment, the buffer 111a can be arranged on the clamping portion 1111b of the clamping member 1111, and the clamping portion 1111b is arranged in an arm structure. Alternatively, both clamping members 1111 of the clamping assembly 111 can be provided with the buffer 111a on the arm structure thereof, and each buffer 111a is located on the side of the arm structure of one clamping member 1111 facing the arm structure of the other clamping member 1111, so as to contact the test tube carrier 200 when the clamping assembly 111 clamps the test tube carrier 200. The arm structure can be provided with a plurality of buffers 111a along the length direction thereof in sequence; the buffers 111a on the two arm structures can be oppositely arranged in the first direction, or can be arranged in a staggered manner. The specific implementation can be arranged according to actual needs, which is not limited herein.

[0078] Please refer to Figure 3 In the embodiment of the present application, the clamping module 11 further comprises a transmission assembly 114 connected between the two clamping members 1111, so as to drive the other clamping member 1111 to move reversely when one clamping member 1111 moves.

[0079] In this way, when one clamping member 1111 moves in the negative direction of the first direction under the driving of the first driving assembly 113, it can drive the other clamping member 1111 to move in the positive direction of the first direction through the transmission assembly 114, so that the two clamping members 1111 can move towards each other to clamp the test tube carrier 200 to be clamped. Similarly, when one clamping member 1111 moves in the positive direction of the first direction under the driving of the first driving assembly 113, it can drive the other clamping member 1111 to move in the negative direction of the first direction through the transmission assembly 114, so that the two clamping members 1111 can move away from each other to release the clamped test tube carrier 200.
