The induction signal of the first infrared sensor 13 controls the first motor 31 to stop working through the controller, so that the placement seat 2 is located at a set position in the frame 1.
[0058] With reference to Figure 3 and Figure 4 Two wheel seats 14 are fixedly arranged on the front side of the bottom plate 11 along the length direction, and a roller 141 is rotatably connected to the wheel seat 14.

The second driving mechanism 5 drives the moving plate 4 to drive the sample outlet adapter 41 to be connected with the sample inlet hole of the microfluidic chip 21 in a straight line direction, so as to improve the accurate connection between the sample outlet adapter 41 and the sample inlet hole of the microfluidic chip 21. In addition, the sample outlet adapter 41 and the sample inlet hole of the microfluidic chip 21 are prevented from being laterally extruded, so as to prevent gas from entering the microfluidic chip 21, thereby affecting the quality of the microfluidic chip 21.
[0060] With reference to Figure 4 and Figure 5 , the second driving mechanism 5 comprises a second motor 51 and a second screw rod 52. The second motor 51 is installed on the frame 1.

The second sliding blocks of the two second linear guide rails 53 are fixedly arranged on the side walls of the moving plate 4, respectively. The second guide rails are perpendicular to the second screw rod 52. The second motor 51 drives the moving plate 4 to move along the second guide rails through the second screw rod 52, so as to improve the stability of the connection between the sample outlet adapter 41 on the moving plate 4 and the sample inlet hole of the to-be-connected component.

The second motor 51 drives the cross arm 54 arranged in the frame 1 to rotate through the second screw rod 52, thereby pushing the moving plate 4 to move up and down, so as to reduce the installation space in the moving direction of the moving plate 4. Specifically, the connecting plate 16 is fixed between the two vertical plates 15, and the cross arm 54 is arranged between the connecting plate 16 and the moving plate 4. The cross arm 54 comprises a first arm rod 541 and a second arm rod 542, which are cross-rotatably connected. The surface of the moving plate 4 is fixedly provided with a first lug 42, one end of the first arm rod 541 is hingedly connected with the first lug 42, the second screw rod 52 is threadedly connected with a pushing block 543, and the other end of the first arm rod 541 is hingedly connected with the pushing block 543. The connecting plate 16 is fixedly provided with a second lug 161, the first lug 42 and the second lug 161 are oppositely arranged, one end of the second arm rod 542 is hingedly connected with the second lug 161, the moving plate 4 is slidingly connected with a moving block 544 opposite to the pushing block 543, and the other end of the second arm rod 542 is hingedly connected with the moving block 544.

[0062] With reference to Figure 6 and Figure 7 Two sample outlet adapters 41 are arranged corresponding to one microfluidic chip 21, and the two sample outlet adapters 41 are arranged corresponding to two sample inlet holes of the microfluidic chip 21. The side wall of the sample outlet adapter 41 is provided with a limiting portion 411, the moving plate 4 is fixedly provided with a mounting plate 45, and the moving plate 4 and the mounting plate 45 are provided with a mounting hole 46 in communication at the corresponding positions. The sample outlet adapter 41 extends out of the moving plate 4 through the mounting hole 46, the circumferential side wall of the mounting hole 46 at the connecting position of the moving plate 4 and the mounting plate 45 is provided with a limiting groove 461, the limiting portion 411 is located in the limiting groove 461, and the mounting plate 45 is divided into two parts along the axis direction of the mounting hole 46. There is a gap between the sample outlet adapter 41 and the mounting hole 46, and between the limiting portion 411 and the limiting groove 461. Therefore, when there is a slight misalignment between the sample inlet hole and the sample outlet adapter 41, the sample inlet hole and the sample outlet adapter 41 can be accurately connected and communicated. A sealing ring 47 is sleeved on the sample outlet adapter 41, and the sealing ring 47 is located on the surface of the moving plate 4.
[0063] With reference to Figure 6 and Figure 8The bottom of the moving plate 4 is provided with a waste liquid collecting hopper 6.

The liquid collecting hole 49 is in communication with the waste liquid collecting hopper 6. The upper surface of the moving plate 4 is gradually inclined downward to the liquid collecting hole 49. When the sample outlet connector 41 is separated from the sample inlet hole of the microfluidic chip 21, the waste liquid discharged by the sample outlet connector 41 flows into the waste liquid collecting hopper 6 through the liquid collecting hole 49 on the moving plate 4. When the sample outlet connector 41 is connected to the microfluidic chip 21, the liquid outlet hole is in communication with the communication hole 48. Therefore, the waste liquid for cleaning the internal channel of the microfluidic chip 21 can be conveniently collected in the waste liquid collecting hopper 6.
[0064] With reference to Figure 3 and Figure 8 The waste liquid collecting hopper 6 is in communication with a waste liquid tank 61. The waste liquid tank 61 is connected with a waste liquid pump (not shown in the figure) through a pipeline. The waste liquid tank 61 is provided with a liquid level sensor 62. The liquid level sensor 62 controls the operation of the waste liquid pump through a controller. When the liquid level sensor 62 detects that the waste liquid in the waste liquid tank 61 is too much, the waste liquid in the waste liquid tank 61 is pumped out through the controller.
[0065] The implementation principle of the communication device in the embodiment of the application is that the microfluidic chip 21 is placed in the accommodating groove 22 of the placing seat 2. The placing seat 2 is driven into the frame 1 by the first driving mechanism 3. Then the moving plate 4 is driven by the second driving mechanism 5 to drive the sample outlet connector 41 to be connected to the sample inlet hole of the microfluidic chip 21. Compared with manual connection, the efficiency of connecting the microfluidic chip 21 is greatly improved.
[0066] The embodiment also discloses a cell capture and dyeing instrument. With reference to Figure 9 , the communication device is mounted on the shell 7. The sample inlet end of the sample outlet connector 41 is in communication with the injection pump mechanism in the shell 7 through a pipeline.

The information identifier 8 is a bar code scanner. The information identifier 8 identifies the label information on the microfluidic chip 21, so that the injection pump mechanism injects the corresponding sample into the corresponding microfluidic chip 21, thereby improving the accuracy of the preparation of the microfluidic chip 21.
[0068] With reference to Figure 9 and Figure 11The driving assembly 9 is arranged in the sliding cover 71 and is used for driving the information identifier 8 to sequentially identify information of the plurality of micro-fluidic chips 21. The driving assembly 9 comprises a mounting bracket 91, a third motor 92, a third screw rod 93 and a mounting seat 94. The mounting bracket 91 is fixed in the shell 7. The third motor 92 is mounted on one side of the mounting bracket 91. The third screw rod 93 is rotationally connected to the mounting bracket 91.

The mounting seat 94 is threadedly connected with the third screw rod 93 and is slidably connected with the mounting bracket 91 through a third linear guide rail 95. The third guide rail of the third linear guide rail 95 is fixedly mounted on the mounting bracket 91 and is arranged in parallel with the third screw rod 93. The third sliding block of the third linear guide rail 95 is fixedly mounted on the mounting seat 94. The information identifier 8 is mounted on the mounting seat 94 and faces the label information of the micro-fluidic chip 21. The label information is located at the observation port 121. The third motor 92 drives the third screw rod 93 to drive the mounting seat 94 to move along the third linear guide rail 95, so as to identify information of the to-be-connected components placed in the plurality of accommodating grooves 22, thereby improving the identification efficiency.
[0069] The implementation principle of the cell capture staining instrument is as follows: the micro-fluidic chip 21 is placed in the accommodating groove 22 of the placing seat 2. The placing seat 2 is driven into the frame 1 by the first driving mechanism 3. The pipeline is cleaned by the injection pump mechanism. Then the liquid collected through the liquid collecting hole 49 arranged on the moving plate 4 flows into the waste liquid collecting bucket 6. Then the second driving mechanism 5 is automatically controlled by the controller to drive the sample outlet joint 41 on the moving plate 4 to be connected with the sample inlet hole of the micro-fluidic chip 21. The internal channel of the micro-fluidic chip 21 is cleaned by the injection pump mechanism. Then the waste liquid is discharged into the waste liquid collecting bucket 6 through the communication hole 48 connected with the liquid outlet hole. After the micro-fluidic chip 21 is cleaned, the sample collected by the injection pump mechanism is injected into the internal channel of the micro-fluidic chip 21 to prepare the sample, thereby improving the sample preparation efficiency of the micro-fluidic chip 21.
