Description

technical field [0001] The invention belongs to the field of automatic instruments, and in particular relates to a three-dimensional intelligent liquid preparation system. Background technique [0002] With the development of social economy and science and technology, more and more industries involve the precise management, dilution, mixing, homogenization and constant volume of liquid items. The most typical is the process of laboratory solution preparation, which needs to use a large number of standard samples for precise preparation to form a mixed solution. This kind of work has high technical requirements, complex process, various types of tools involved, cumbersome process, long operation cycle, and is prone to errors, which will bring great economic losses and often cannot be traced back. Come a tough challenge. [0003] The problem that prior art exists is: [0004] 1) The existing liquid preparation workbench product technology focuses on the process itself of pi...

Problems solved by technology

[0004] 1) The existing liquid preparation workbench product technology focuses on the process itself of pipetting and dilution, but there is a lack of intelligent management of samples: there is a lack of optimal management of sample inventory, it is impossible to ensure that all samples are within the shelf life, and it is impossible to predict the consumption of samples It is necessary to remind users to supplement in time; the preparation process lacks the means of sample identification and confirmation, and it is impossible to confirm whether the currently used sample meets the preparation requirements; after the preparation is completed, there is no method for sample quality traceability, and it is impossible to trace the error after the preparation result is wrong. steps and reasons

[0005] 2) The existing liquid preparation workbench product technology does not fully consider the volatilization and deterioration of the liquid during the liquid preparation process: or directly use an open container, ignoring the volatilization and deterioration during the liquid preparation process; or use a soft rubber cover The sample bottle, through the way of physically puncturing the bottle cap with the sampling needle, can reduce the volatilization and deterioration of the liquid while obtaining the liquid. This method has two disadvantages: one is that the cap can no longer be sealed after the hole is pierced, which is not conducive to long-term storage , after the preparation process is completed, the container cover needs to be replaced manually; secondly, because the liquid-taking needle is often very thin, if it is used for a long time to pierce the colloidal bottle cap, it will gradually wear out until it cannot be pierced or directly damaged, which reduces the life of the liquid-taking needle. Life expectancy, will bring unnecessary cost to user maintenance

[0006] 3) Furthermore, the existing liquid preparation workbench product technology has not yet reached a good balance in terms of sample bottle capacity, sample bottle quantity and instrument footprint: or the number of sample bottles is guaranteed, but large-capacity sample bottles cannot be used; Or use larger vials with fewer vials, or use more larger vials but take up more floor space on the instrument

[0009] The current liquid preparation workbench products are difficult to adapt to the above-mentioned complex preparation process, the degree of simulation of the manual operation process is low, the function is simplified and single, or the lack of complete sample management and quality traceability, or it is difficult to prepare more than 200 samples. Or lack of a better technical solution to solve the liquid volatilization during the preparation process

In short, there is still a lot of room for improvement in the user experience brought by current products and technologies.
