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 increase the complexity of the test equipment, and the staff is also required to do a good job of cleaning.

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figure 1-3 This is an embodiment of the utility model, which is used for the upper cleaning device of the laboratory robot. The cleaning device includes a waste liquid pool 1 and a test tube clamping device 13. The waste liquid pool 1 is used to collect waste liquid in the test tube and rinse the test tube. It is installed in a fixed installation manner. The test tube clamping device 1 is used to shake the test tube, pour out waste liquid, etc. It is installed in a manner that can move in the longitudinal direction. Therefore, this embodiment lowers the test tube clamping device 13 to make the test tube close to the waste liquid pool 1, so as to rinse the test tube. Figure 1 - Figure 3 It can be seen that the upper cleaning device has a longitudinally mounted cylinder 6, which is fixedly mounted by a cylinder mounting plate 14, and its relative position to the waste liquid pool 1 remains unchanged; the test tube clamping device 13 is mounted on the top of the connecting arm 5, and the telescopic shaft 7 of the cylinder 6 is downward and fixedly connected to the connecting arm 5, so the test tube clamping device 13 can be controlled by the cylinder 6 to complete the longitudinal movement.

[0026] like Figure 4As shown, similar to the prior art, the test tube clamping device 13 includes a pair of clamping arms 8 symmetrically arranged on the left and right sides, and an arc-shaped clamping groove 81 is longitudinally arranged at the front end of the clamping arm 8. The clamping groove 81 is used to improve the clamping stability and prevent the test tube 3 from being deflected relative to the clamping arm 8. The rear end of the clamping arm 8 is installed on the rotating electric claw 131. The rotating electric claw 131 used in this embodiment can control the two clamping arms 8 to open and clamp the test tube, and can also control the clamping arm 8 to swing left and right to oscillate the test tube or dump waste liquid, and can also control the test tube to flip to face downward. On this basis, a baffle 15 is arranged in the middle area of ​​each clamping arm 8, and the two baffles 15 extend toward each other to the front and are misaligned and fitted (and there is no friction between the two), and when the clamping arm 8 is opened, the two are still in a fitted state, so as to prevent the splashing liquid from splashing onto the rotating electric claw 131 and the active part of the clamping arm 8, so as to avoid damaging the equipment and affecting the normal operation of the equipment.

[0027] To ensure that the test tube clamping device 13 has a safe working space, a shield is provided above the test tube clamping device 13, such as Figure 5 and Figure 6 As shown, the shield is divided into shield I2 and shield II4, wherein shield II4 is installed on the rotating electric claw 131 and covers it; shield I2 is used to protect the clamping arm 8 and the test tube, and has shield plates around it, and the shield plate close to the side of shield II4 has an isolation hole 203 for avoiding the clamping arm 8. In addition, the top and bottom of shield I2 are open, and the top is an avoidance hole 201 for avoiding the test tube from being taken, placed, shaken and flipped.

[0028] Regarding the longitudinal movement of the test tube clamping device 13, this embodiment adopts a cylinder 6 positioned and installed on other parts of the laboratory robot. The telescopic shaft 7 of the cylinder 6 is vertically downwardly arranged and fixedly connected to a longitudinally arranged connecting arm 5, and the rotating electric claw 131 is installed at the top of the connecting arm 5. Therefore, when the telescopic shaft 7 is extended, the test tube clamping device 13 moves downward, and when the telescopic shaft 7 is retracted, the test tube clamping device 13 moves upward, and when the test tube clamping device 13 is in the highest position and the lowest position, the lower edge of the mask I2 is always located in the waste liquid trough 16 of the waste liquid pool 1.

[0029] Regarding waste liquid pool 1, Figure 7 As shown, it has a waste liquid tank 16 with an open top, combined with Figure 8It can be seen that the waste liquid tank 16 is divided into a waste liquid tank I161, a waste liquid tank III163 and a waste liquid tank II162, which are arranged side by side in sequence, and waste liquid pipes II10, III11 and I9 are respectively arranged at the bottom of the waste liquid tank 1, wherein the waste liquid tank III163 is separated from the waste liquid tank I161 and the waste liquid tank II162 by the isolation plates 164 on both sides to prevent the flushing waste liquid from entering the waste liquid tanks on both sides, and correspondingly, a avoidance port 202 is arranged at the lower edge of the shield plate of the shield I2; Figure 8 In the embodiment, the bottom of the waste liquid tank III163 is connected to the waste liquid pipe I9 through a drainage hole 166, and the drainage hole 166 is divided into two symmetrical parts by a central plate 165 disposed laterally in the middle; Fig. 9 As shown, a liquid through hole 167 is arranged in the pool body of the waste liquid pool 1, the lower port of the liquid through hole 167 is located at the lower part of one side of the waste liquid pool 1, and a water inlet pipe 12 is installed, the upper port is located in the middle position of the top of the center plate 165, and a flushing pipe 17 is installed in the upper port, and the flushing pipe 17 extends upward to exceed the upper edge of the waste liquid pool 1. When the cylinder 6 controls the test tube clamping device 13 to descend, the upper part of the flushing pipe 17 is inserted into the test tube 3.

[0030] The test tube clamping device 13 can control the test tube to pour the waste liquid into the waste liquid tank I161 or the waste liquid tank II162, and can also control the test tube to flip over so that the tube mouth is facing the flushing tube 17 in the waste liquid tank III163; the upper cleaning device has a cylinder 6 positioned and installed relative to the waste liquid tank 1, and the telescopic axis of the cylinder 6 is connected to the test tube clamping device 13 through the connecting arm 5, and can control the test tube clamping device 13 to move downward until the flushing tube 17 is inserted into the test tube mouth, and at this time, the isolation plate 164 is stuck in the avoidance opening 202 at the lower edge of the mask I2.

[0031] During the experiment, the test tube is shaken and evenly mixed by shaking the test tube clamping device 13 alternately left and right. The waste liquid tank I161 is set as an acidic waste liquid tank, and the waste liquid tank II162 is set as an alkaline waste liquid tank. The waste liquid is poured into the corresponding waste liquid tank by deflection of the test tube clamping device 13. This can avoid the mixing and reaction of the waste liquid and is also convenient for the classification and treatment of the waste liquid. After the waste liquid is poured, the test tube clamping device 13 controls the test tube 3 to flip over so that the test tube mouth faces downward. At this time, the test tube 3 is located directly above the flushing tube 17, and then the test tube clamping device 13 is controlled to descend by the cylinder 6. Fig.10 In the state shown, the flushing operation can be performed at this time; during the flushing process, the flushing liquid flowing out of the test tube is close to neutral, so it directly enters the waste liquid tank III163 and is discharged from the waste liquid pipe I9.

[0032] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
