[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0024] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a sample tool track switching mechanism according to an embodiment of the present application is shown. Figure 2 A schematic diagram of the structure of a track assembly according to an embodiment of the present application is shown. An embodiment of the present application provides a track assembly, which includes a sample device track switching mechanism, and also includes a first track 10 and a second track 20 arranged in parallel and at intervals.

[0025] Specifically, the sample device track switching mechanism includes: a driving assembly 40, a first channel assembly 50 and a second channel assembly 60. The driving assembly 40 is directly connected to the first channel assembly 50, and is used to drive the first channel assembly 50 to switch between the first position and the second position. When the first channel assembly 50 is located at the first position, the first channel assembly 50 is connected in series to the first track 10; when the first channel assembly 50 is located at the second position, the first channel assembly 50 is connected in series to the second track 20.

[0026] In addition, the second channel component 60 abuts against the driving component 40 or the first channel component 50, and moves from the second position to the exit position under the drive of the driving component 40 or the drive of the first channel component 60. When the second channel component 60 is in the second position, the second channel component 60 is connected in series to the second track 20. When the second channel component 60 is in the exit position, the second channel component 60 is located outside the second track 20.

[0027] The track assembly and sample device track switching mechanism described above, because the driving assembly 40 is directly connected to the first channel assembly 50, the second channel assembly 60 moves under the drive of the driving assembly 40 or driven by the first channel assembly 60, that is, it can directly drive the first channel assembly 50 to move and synchronously drive the second channel assembly 60 to move, so as to realize the switching of the first channel assembly 50 between the first position and the second position, and realize the movement of the second channel assembly 60 from the second position to the exit position. Compared with the track switching mechanism in the related art, the transmission of force when the driving mechanism drives the second channel assembly 60 is more direct and effective, the transmission efficiency is higher, the noise is lower, and the service life of the entire mechanism is longer.

[0028] When the first channel assembly 50 is located at the first position, the first channel assembly 50 is connected in series to the first track 10, and the instrument carrier 100 in the first track 10 and the sample instrument 200 thereon can enter the first channel assembly 50, and the instrument carrier 100 and the sample instrument 200 thereon that have entered the first channel assembly 50 can also enter the first track 10. When the first channel assembly 50 is located at the second position, the second channel assembly 60 moves from the second position to the exit position, and the first channel assembly 50 is connected in series to the second track 20, and the instrument carrier 100 in the second track 20 and the sample instrument 200 thereon can enter the first channel assembly 50, and the instrument carrier 100 and the sample instrument 200 thereon that have entered the first channel assembly 50 can also enter the second track 20. Similarly, when the second channel assembly 60 is located at the second position, the second channel assembly 60 is connected in series to the second track 20, and the instrument carrier 100 in the second track 20 and the sample instrument 200 thereon can enter the second channel assembly 60, and the instrument carrier 100 and the sample instrument 200 thereon on the second channel assembly 60 can also enter the second track 20.

[0029] The instrument carrier 100 includes but is not limited to a device such as a bracket, a box, a trough, etc. that can place the sample instrument 200; the sample instrument 200 includes but is not limited to a sample tube, a sample cup, a container, etc.

[0030] It should be noted that the movement directions of the first channel assembly 50 and the second channel assembly 60 are as follows: Figure 2 In the Y-axis direction shown in FIG, the movement direction of the tool carrier 100 on the first track 10, the second track 20, the first channel assembly 50, and the second channel assembly 60 is as shown in FIG. Figure 2 The X-axis direction is shown in .

[0031] In one embodiment, the track assembly further includes a third track 30 arranged in parallel and spaced relation with the first track 10. In addition, the driving assembly 40 is further used to drive the first channel assembly 50 to switch between the first position and the third position. When the first channel assembly 50 is located at the third position, the first channel assembly 50 is connected in series to the third track 30. In this way, since the driving assembly 40 can also drive the first channel assembly 50 to move to the third position, the first channel assembly 50 can be moved to any of the first position, the second position and the third position, and thus the instrument carrier 100 and the sample instrument 200 thereon on any of the first track 10, the second track 20 and the third track 30 can enter the first channel assembly 50 according to actual needs, and the instrument carrier 100 and the sample instrument 200 thereon on the first channel assembly 50 can enter any of the first track 10, the second track 20 and the third track 30.

[0032] The third track 30 and the second track 20 are located at two opposite sides of the first track 10 .

[0033] See also Figure 1 and Figure 2 In one embodiment, the sample device track switching mechanism further includes a support frame 70 and an elastic reset member 91. The second channel assembly 60 is connected to the support frame 70 through the elastic reset member 91, and the elastic reset member 91 is used to move the second channel assembly 60 from the exit position to the second position. Specifically, one end of the elastic reset member 91 is connected to the support frame 70, and the other end of the elastic reset member 91 is connected to the second channel assembly 60, so that the second channel assembly 60 moves from the exit position to the second position. In this way, on the one hand, under the drive of the drive assembly 40, the first channel assembly 50 moves synchronously from the first position to the second position, and the second channel assembly 60 moves from the second position to the exit position, so that the elastic reset member 91 is elastically deformed to store elastic potential energy; on the other hand, when the drive assembly 40 drives the first channel assembly 50 to move from the second position to the first position, at the same time, under the elastic restoring force of the elastic reset member 91, the second channel assembly 60 can be returned from the exit position to the second position.

[0034] It can be seen that the driving component 40 can directly drive the first channel component 50 to move to any position among the first position, the second position and the third position, and can also synchronously drive the first channel component 50 and the second channel component 60 to move, so as to realize the movement of the second channel component 60 from the second position to the exit position.

[0035] Optionally, the elastic return member 91 includes but is not limited to a spring, an elastic strip, and the like.

[0036] See also Figure 1 and Figure 2 In one embodiment, the sample device track switching mechanism further includes a guide assembly 80 disposed on the support frame 70. The first channel assembly 50 and the second channel assembly 60 are both connected to the guide assembly 80. In this way, the guide assembly 80 guides the first channel assembly 50 and the second channel assembly 60, and under the drive of the drive assembly 40, the operation stability of the first channel assembly 50 and the second channel assembly 60 can be improved. In addition, the guide assembly 80 can be set as one, and the first channel assembly 50 and the second channel assembly 60 share the same guide assembly 80, which can simplify the structure; or it can be set as two, and they are respectively set corresponding to the first channel assembly 50 and the second channel assembly 60.

When the first channel assembly 50 moves to the first notch 11, it is located at the first position, and is connected in series to the first track 10. When the first channel assembly 50 moves to the second notch 21, it is located at the second position, and is connected in series to the second track 20. When the first channel assembly 50 moves to the third notch 31, it is located at the third position, and is connected in series to the third track 30.

One end of the elastic reset member 91 is connected to the support frame 70, and the other end of the elastic reset member 91 is connected to the second channel assembly 60, so that the second channel assembly 60 moves from the exit position to the second position; the stopper 92 is arranged corresponding to the second position, and is used to abut against the second channel assembly 60 located at the second position. In this way, under the elastic force of the elastic reset member 91, when the second channel assembly 60 returns from the exit position to the second position, the stopper 92 abuts against the second channel assembly 60, and the second channel assembly 60 is limited, so that the second channel assembly 60 is accurately located at the second position. In addition, when the driving assembly 40 drives the first channel assembly 50 to move from the first position to the third position, that is, the first channel assembly 50 is connected to the third guide rail in series, and under the action of the elastic reset member 91 and the stopper 92, the second channel assembly 60 remains in the second position.

[0041] In some embodiments, the drive component 40 includes but is not limited to a pulley drive structure, a sprocket drive structure, a motor screw drive structure, a cylinder drive structure, etc., and can be flexibly adjusted and set according to actual needs, as long as it can drive the first channel component 50 and the second channel component 60 to move respectively.

[0042] See also Figure 1 and Figure 2 In a specific embodiment, the driving assembly 40 includes a driving motor (not shown in the figure), a driving wheel 41 and a driven wheel 42 rotatably disposed on a support frame 70, and a transmission element 43 connecting the driving wheel 41 and the driven wheel 42. The driving motor is connected to the driving wheel 41. The transmission element 43 can drive the first channel assembly 50 and the second channel assembly 60 to move respectively. In this way, when the driving motor is working, the driving wheel 41 is driven to rotate, the driving wheel 41 drives the transmission element 43 to move, and the transmission element 43 can drive the first channel assembly 50 and the second channel assembly 60 to move accordingly.

[0043] The transmission element 43 includes but is not limited to a transmission belt or a transmission chain, and the driving wheel 41 and the driven wheel 42 are arranged corresponding to the transmission element 43 .

[0044] See also Figure 1 and Figure 2 In one embodiment, the first channel assembly 50 includes a first channel body 52, a first support seat 53 and a first connecting member 54. The first channel body 52 is used to transport the device carrier 100, and the first channel body 52 is connected to the first support seat 53. The first support seat 53 is connected to the first connecting member 54, and the first connecting member 54 is connected to the driving assembly 40.

[0045] In addition, the second channel assembly 60 includes a second channel body 62, a second support seat 63 and a second connecting member 64. The second channel body 62 is used to transport the device carrier 100, the second channel body 62 is connected to the second support seat 63, and the second support seat 63 is connected to the second connecting member 64. Among them, the driving assembly 40 or the first connecting member 54 is provided with an abutting member 55, and the abutting member 55 is in abutment with the second connecting member 64.

[0046] Specifically, the first support seat 53 is installed on the first slider 51 . The second support seat 63 is installed on the second slider 61 .

[0047] Specifically, the abutment member 55 is provided with a first abutment portion 551, and the second abutment portion 641 is provided on the second connection member 64. When the driving assembly 40 drives the first connection member 54 to drive the first channel body 52 to move from the first position to the second position, the first abutment portion 551 and the second abutment portion 641 abut against each other, and the second connection member 64 is driven to move by the second abutment portion 641, and the second connection member 64 drives the second channel body 62 to move synchronously from the second position to the exit position. Optionally, the first abutment portion 551 and the second abutment portion 641 each include but are not limited to various shapes and structures such as abutment blocks, abutment plates or abutment sheets. Among them, when the first abutment portion 551 and the second abutment portion 641 abut against each other in a face-to-face manner, the movement stability of the second channel assembly 60 can be improved. In addition, the setting of the abutment member 55 makes the stability of the track-changing mechanism better when the first channel assembly 50 or the driving assembly 40 drives the second channel assembly 60 to move, while reducing the wear of the first channel assembly and the second channel assembly, and extending the service life of the track-changing mechanism.

[0048] Specifically, the first connecting member 54 is, for example, fixedly connected to the transmission element 43, including but not limited to being fixed to the transmission element 43 by fasteners such as bolts, pins, rivets, and clips, or being fixed to the transmission element 43 by various methods such as bonding and welding. In addition, the second connecting member 64 may also be similar to the first connecting member 54, and is, for example, fixedly connected to the transmission element 43, including but not limited to being fixed to the transmission element 43 by fasteners such as bolts, pins, rivets, and clips, or being fixed to the transmission element 43 by various methods such as bonding and welding; of course, the second connecting member 64 may also not be connected to the transmission element 43, but may, for example, abut and cooperate with the first abutting portion 551 of the first connecting member 54.

[0049] See also Figure 1 In one embodiment, the sample device track switching mechanism further includes a position sensing component 93 disposed on the support frame 70, and the position sensing component 93 is used to sense the positions of the first channel component 50 and the second channel component 60. In this way, the specific positions of the first channel component 50 and the second channel component 60 are sensed and identified by the position sensing component 93, and whether the first channel component 50 and the second channel component 60 have moved to the position can be determined according to the specific positions of the first channel component 50 and the second channel component 60, and the specific positions of the first channel component 50 and the second channel component 60 can be adjusted accordingly and in time, thereby improving the position accuracy of the first channel component 50 and the second channel component 60.

[0050] It should be noted that the position sensing component 93 includes but is not limited to an optical coupling sensor, a magnetic sensor, an ultrasonic sensor, etc. In this embodiment, the position sensing component 93 includes a sensing body 931 disposed on the support frame 70 and an identification portion 932 disposed on the second channel component 60. When the second channel component 60 moves to the second position, the sensing body 931 can sense the identification portion 932. When the second channel component 60 moves away from the second position, the sensing body 931 cannot sense the identification portion 932. In this way, whether the second channel component 60 moves to the second position is determined by whether the sensing body 931 senses the identification portion 932, so that the second channel component 60 can accurately move to the second position.

[0051] See also Figure 1 and Figure 2 In one embodiment, two drive assemblies 40 are provided, and the two drive assemblies 40 are respectively provided corresponding to the first channel assembly 50 and the second channel assembly 60, so as to respectively drive the first channel assembly 50 and the second channel assembly 60 to move. In this way, the first channel assembly 50 and the second channel assembly 60 move independently under the drive of the corresponding drive assembly 40. Specifically, the first channel assembly 50 moves on the first track 10, the second track 20, and the third track 30 under the drive of one of the drive assemblies 40; at the same time, the second channel assembly 60 moves on the second track 20 and the exit position under the drive of the other drive assembly 40.

[0052] In one embodiment, an in vitro diagnostic device includes the track assembly of any one of the above embodiments.

[0053] In the above-mentioned in vitro diagnostic device, since the driving component 40 is directly connected to the first channel component 50, the second channel component 60 moves under the drive of the driving component 40 or driven by the first channel component 60, that is, it can directly drive the first channel component 50 to move and synchronously drive the second channel component 60 to move, so as to realize the switching of the first channel component 50 between the first position and the second position, and realize the movement of the second channel component 60 from the second position to the exit position. Compared with the track switching mechanism in the related art, the transmission of force when the driving mechanism drives the second channel component 60 is more direct and effective, the transmission efficiency is higher, the noise is lower, and the service life of the entire mechanism is longer.
