Detailed Description
Referring to fig. 1, the automatic laboratory solution stirring device provided by the invention comprises: the device comprises a shell 1, a rotary stirring mechanism 2, a driving motor 3, a sampling tube 4, an electric pump 5, a spectrophotometer 6 and a control module.
The rotary stirring mechanism 2 is rotatably arranged in the shell 1, the driving motor 3 is arranged outside the shell 1, and the driving motor 3 is connected with the rotary stirring mechanism 2 and used for driving the rotary stirring mechanism 2 to rotate so as to stir the solution in the shell 1.
The two opposite sides of the shell 1, which are positioned on the rotating plane of the rotary stirring mechanism 2, are respectively provided with a sampling port 11 and a reflux port 12. The first end of the sampling tube 4 is communicated with the sampling port 11, the second end of the sampling tube passes through the sample chamber of the spectrophotometer 6 to be communicated with the reflux port 12, and the electric pump 5 is arranged on the sampling tube 4. In this way, under the working state of the electric pump 5, the solution in the shell 1 flows through the sampling tube 4 from the sample chamber of the spectrophotometer 6, and the solution in the shell 1 enters the sampling tube 4 from the sampling port 11 and flows back into the shell 1 from the backflow port 12, so that the real-time measurement of the transmittance of the solution in the shell 1 by the spectrophotometer 6 is realized, and the degree of uniformity of the solution mixing is judged according to the change trend of the transmittance output by the spectrophotometer 6.
Meanwhile, in the present embodiment, the solution in the housing 1 is circulated in the direction along the rotation axis of the rotary stirring mechanism 2 by the sampling tube 4, which is advantageous for mixing the solutions at both sides opposite to the rotation plane of the rotary stirring mechanism 2, thereby avoiding the delamination of the solution in the housing 1.
The control module comprises a spectrum curve drawing unit, a processing unit and an execution control unit.
The spectrum curve drawing unit is connected with the spectrophotometer 6 and is used for acquiring the light transmittance detection value of the spectrophotometer 6 on the sample in the sample chamber in real time and drawing a spectrum curve. In this way, in the present embodiment, the light transmittance of the solution output at different times in the housing 1 is linearly analyzed, which is favorable for more intuitively obtaining the light transmittance change of the solution at different times in the housing 1, so as to determine the uniformity degree in the solution mixing process.
The processing unit is connected with the spectrum curve drawing unit and is used for obtaining the maximum value N of the spectrum curve in the latest preset time period max And a minimum value N min Average value N of (2) ave And is used for judging the uniformity degree of the solution according to the comparison result of the spectrum curve and the average value in the latest preset time period.
In practice, the maximum value N can be passed max Difference from average or minimum value N min And average value N ave And judging the uniformity of the solution.
In this embodiment, the processing unit operates in the following manner: the processing unit is based on the average value N ave And a preset float value f x Drawing a reference interval, wherein the reference interval is N as an upper limit value on the latest preset time period ave +f x And the lower limit value is N ave -f x Is a rectangular region of the panel. The processing unit is used for calculating the area value of the spectrum curve positioned outside the reference interval in the latest preset time period and judging the uniformity degree of the solution according to the calculation result. I.e. the greater the area value of the spectral curve over the most recent preset time period outside the reference interval, the lower the degree of homogeneity of the solution.
The execution control unit is connected with the processing unit and the driving motor 3, and is used for controlling the driving motor 3 to work according to the judging result of the processing unit. For example, if the degree of uniformity of the solution reaches the standard, the execution control unit controls the driving motor 3 to stop operating to stop stirring the solution; if the solution uniformity is low, the execution control unit controls the driving motor 3 to continue to work so as to further stir the solution to improve the solution uniformity.

Each stage of working mode is associated with a corresponding uniform degree interval range, and the execution control unit is used for adjusting the working mode of the driving motor 3 according to the uniform degree acquired by the processing unit.
In this way, when the processing unit determines that the solution uniformity is lower, the execution control unit controls the driving motor 3 to work in a higher-power working mode so as to drive the rotary stirring mechanism 2 to stir at a higher rotating speed, thereby being beneficial to improving the solution stirring efficiency. And along with the improvement of the uniformity degree of the solution, the rotating speed of the rotary stirring mechanism 2 is gradually reduced, so that excessive stirring is avoided, and redundant energy consumption is avoided.
Specifically, in this embodiment, the processing unit is configured to measure the uniformity of the solution according to the following formula:
r＝A×S 1 /S 0 wherein A is a calculation constant, A is more than or equal to 10 and less than or equal to 100, S 1 For the area value of the spectral curve lying outside the reference interval for the latest preset time period, S 0 The area value of the reference section.
Thus, the solution uniformity is quantized by calculating the magnitude r, thereby being beneficial to the imaging judgment of the solution uniformity and facilitating the accurate control of the driving motor 3.
In this embodiment, the processing unit is further configured to compare the maximum value N of the spectrum curve max And a minimum value N min The processing unit is used for judging the next solution uniformity degree after the reference time is delayed by a preset time period. Therefore, the time for judging each spectrum curve of the processing unit is accurately controlled, real-time detection of the uniformity of the solution is realized, redundant work is reduced, the workload of the processing unit is reduced, and the working efficiency is improved. In specific implementation, the processing unit may also periodically determine the uniformity of the solution.
