Description

Technical Field

[0001] The present application relates to the technical field of automatic liquid transfer workstations, and in particular to an automatic liquid transfer workstation. Background Art

[0002] Automatic pipetting workstations are commonly used automated equipment in laboratories, which are used to perform liquid pipetting operations accurately and efficiently. Such equipment usually includes components such as a liquid processing head, a workbench, a liquid processor and a control system. It can automatically complete the operations of aspirating, dispensing, mixing and transferring liquids according to preset programs. However, the existing automatic pipetting workstations still have the following problems when in use.

[0003] When the existing automatic pipetting workstation is in operation, the pipette needs to be cleaned and the pipette tip replaced after each pipetting operation to prevent cross contamination, which will generate more waste liquid and disposable tips. The generated waste liquid and disposable tips are often placed in the corresponding collection box, which are manually cleaned and replaced when the collection box is full. Improper operation is prone to occur, such as knocking over the collection box, which causes cross contamination between the waste liquid in the collection box or the pollutants in the waste tip and the liquid specimen to be tested, affecting the accuracy of the test result. At the same time, if the liquid specimen to be tested contains infectious substances, manual direct cleaning is also likely to increase the risk of infection.

The automatic liquid handling device 4 will position the liquid handling gun on the target container during operation, and the suction head in the pipette will enter the liquid, and a certain amount of liquid will be sucked by negative pressure. The pipette moves the sucked liquid to the target container, and the pipette releases the liquid in the target container. After completing a liquid handling operation, the pipette needs to be cleaned to prevent cross contamination. The cleaning procedure usually includes the steps of sucking washing liquid, discharging washing liquid, sucking air, etc. The working principle of the above technical features is a well-known technology in the art, so it will not be described in detail here.

[0026] By adopting the above technical solution, a waste tank 26 is arranged under the workbench 3, and a waste liquid collection mechanism and a part of the waste liquid collection mechanism are arranged in the waste tank 26. The bottom of the waste liquid collection mechanism and the waste material collection mechanism are both provided with a moving mechanism. The waste liquid collection mechanism and the waste material collection mechanism can facilitate the preliminary adsorption and disinfection treatment of the collected waste liquid and waste material, and then the waste material is taken out of the workbench 3 by the moving mechanism, so that the waste liquid and waste material on the workbench 3 are automatically cleaned and collected;
