[0002] In the existing robot for testing, the test tube clamping device is used to oscillate the test tube, and the residual liquid can also be poured into the waste liquid tank. For the cleaning of the test tube, the test tube in the test tube clamping device is first grasped by a manipulator, and then moved to a special test tube cleaning device for cleaning. For example, the patent with the announcement number CN220920336U discloses an automated medical test tube cleaning device, in which a mounting seat for fixing the test tube is provided, and a guide seat with a nozzle is provided under the mounting seat. When in use, the test tube needs to be inverted and installed in the test tube hole of the mounting seat, and then the lower pump water tank is started to rinse the test tube. For this cleaning method, firstly, the manipulator is required to perform the operation of transferring the test tube, and secondly, an independent cleaning space is required, and there will be liquid splashing during cleaning. In addition, after the cleaning is completed, the manipulator is required to transfer the test tube to the test tube rack. Therefore, this cleaning method will not only reduce the efficiency of the test operation, but also require the staff to do a good job of cleaning. Summary of the invention

[0003] The utility model aims to provide a lower cleaning device for an assay robot, which independently provides a cleaning portion that can move longitudinally.

The ends of the clamping arms 15 are installed on the rotating electric claw 12, and the rotating electric claw 12 controls the clamping arms 15 to complete various operations on the test tube, such as controlling the test tube to flip to the test tube mouth downward. In addition, in order to prevent liquid from splashing onto the rotating electric claw 12 and the active parts of the clamping arms 15, a baffle 16 is set in the middle of each clamping arm 15 to prevent liquid from splashing onto the rotating electric claw 12 and the active parts of the clamping arms 15. Figure 3 It can be seen that the two baffles 16 are arranged one after the other and are in a partially offset fit state. In order not to affect the sensitivity of the test tube clamping device, this embodiment sets a 1 mm gap between the two baffles 16 so that there is no friction between the baffles 16.

[0027] from Figure 2 As can be seen from the figure, the test tube clamping device has an isolation cover, in which the top of the rotating electric claw 12 is provided with Figure 4 The top cover II 112 shown in the figure has only the lower part completely open, and its front part extends to the middle area of ​​the clamp arm 15, and an escape opening I 114 for escaping the clamp arm 15 is provided on the front panel, and the top cover II 112 is completely open only at the lower part, and its front part extends to the middle area of ​​the clamp arm 15, and an escape opening I 114 for escaping the clamp arm 15 is provided on the front panel.

In addition, the lower edge of the enclosure of the top cover I 111 has a downwardly extending lower skirt 117, and as shown in FIG. Figure 6 As shown, a pair of symmetrically distributed busbars 118 are disposed at the left and right ends of the operating cavity 115 , and a Y-shaped busbar channel is formed between each pair of busbars 118 .

[0028] About cleaning pool 1, from Figure 1 As can be seen in the figure, the cleaning tank 1 is installed on the upper part of the fixed mounting frame 2, and the fixed mounting frame 2 is fixedly arranged; Figure 7 and Figure 8The cleaning tank 1 has a waste liquid tank 101 with an open top, which is specifically divided into a drainage tank I 102 on the left, a drainage tank II 103 on the right, and an avoidance tank 104 in the middle, wherein drainage tank I 102 and drainage tank II 103 are provided with drainage joints I 7 and II 19 at the bottom, respectively, and the avoidance tank 104 is a rectangular channel with both the top and the bottom open, and a lower tank edge 106 extending downward is provided at the bottom of the avoidance tank 104. In addition, a removable drip tank 105 is provided on the side of the cleaning tank 1, and the drip tank 105 is located below the baffle 16 to receive the liquid dripping along the baffle 16. Figure 1 The upper part of the cleaning part 3 is movably inserted into the avoidance groove 104 from bottom to top, and the lower part is installed on the lifting frame 4. In addition, a cylinder assembly 5 is installed on one side of the fixed mounting frame 2. The telescopic shaft 6 of the cylinder assembly 5 is connected to the lifting frame 4 and can control the longitudinal movement of the entire cleaning part 3. Therefore, the test tube clamping device and the cleaning pool 1 in the lower cleaning device have a fixed installation position, and the cleaning part 3 used for flushing the test tube is installed in a manner that it can move up and down.

[0029] Specifically, Fig. 9 As shown, the cleaning part 3 includes a longitudinally arranged butt joint II 302, a drainage joint II 8 is installed at the lower part of the butt joint II 302, and a receiving groove II 307 with an open top is provided; a butt joint I 301 is provided at the outer periphery of the lower half of the butt joint II 302, a receiving groove I 306 with an open top is reserved between the butt joint I 301 and the butt joint II 302, and an independent drainage pipe port I 304 is provided at the lower part of the receiving groove I 306. Fig.10 As shown, the lower part of the receiving groove II 307 is divided into two symmetrical discharge ports 309 by the center plate 308; a water hole 310 is opened in the butt pipe II 302, the lower end of the water hole 310 is located on the side of the cleaning part 3, and the water inlet pipe joint 305 is installed, and the upper end is located in the middle of the front of the center plate 308, and a flushing pipe 303 is longitudinally installed at the upper end. Fig.11 As can be seen in FIG. 1 , the upper portion of the butt-joint pipe II 302 is inserted from the lower port of the avoidance groove 104 , and the flushing pipe 303 extends to exceed the upper port of the avoidance groove 104 .

[0030] In this embodiment, the two Y-shaped confluence channels in the top cover I 111 are respectively opposite to the drainage trough I 102 and the drainage trough I 103. When the waste liquid in the test tube is poured out, the confluence plate 118 can backflow the waste liquid to avoid splashing of the waste liquid. After the waste liquid is poured out, the test tube cleaning step is entered.

[0031] from Fig.11It can be seen that when the flushing operation is not performed, the upper edge of the butt joint pipe II 302 does not exceed the upper end of the avoidance groove 104, and the lower groove edge 106 is inserted into the receiving groove I 306. In the figure, the test tube 11 has been turned over to open downward, and the test tube mouth is facing the flushing pipe 303; the cylinder assembly 5 is started to move the entire cleaning part 3 to Fig.12 In the state shown, the upper part of the flushing pipe 303 is inserted into the test tube, and the test tube mouth is located in the receiving groove II 307. During flushing, the water flows down along the inner wall after hitting the bottom of the test tube, thereby cleaning the residual liquid attached to the inner wall, and the flushing waste liquid falls into the receiving groove II 307 and flows out from the drainage joint I I8; because the lower groove edge 106 is always inserted into the receiving groove I 306, the waste liquid entering the gap between the avoidance groove 104 and the docking pipe I I302 will flow into the receiving groove I 306 along the lower groove edge 106, and finally flow out through the drainage pipe mouth I 304. After the cleaning is completed, first control the cleaning part 3 to descend to Fig.11 The test tube is positioned as shown, and then the test tube clamping device flips the test tube to a position where the test tube mouth faces upward, and then the robot device grabs the test tube and places it on the test tube rack.
