Problems solved by technology

[0004] The problem is that when the existing machinery and equipment operate the pipette, it usually only has the function of clamping and pressing, and the pipetting volume cannot be adjusted
In actual use, only a large number of pipette guns with different ranges can be prepared in advance, and the machine equipment will grab the pipette guns with corresponding ranges according to the volume of liquid to be pipetted to perform the pipetting operation, which is not only easy to make mistakes during the use of the instrument The problem of the pipette gun, and the overall high cost of use

Embodiment 1

[0051] Please refer to figure 1 with figure 2 The pipette gun 1 widely used in scientific research and analysis now has a scale observation window 11 on the gun body, and a range dial 12 is provided on the top of the gun body. Before using the pipette gun 1 , it is necessary to adjust the volume range of the pipette gun by rotating the volume dial 12 while observing the range value in the scale observation window 11 . The scale observation window 11 includes two parts, an integer area 111 and a decimal scale area 112. When reading, add the number displayed in the integer area 111 to the value corresponding to the scale of the decimal scale area 112, which is the current range of the pipette 1.

[0052] Please refer to Figure 3-5 , the embodiment of the present invention provides a pipette gun range adjustment device, including a bracket 2 for placing the pipette gun 1, a camera 3 for capturing the range value image of the pipette gun 1 is provided on the bracket 2 and a di...

Embodiment 2

[0071] The difference between this embodiment and Embodiment 1 is that after the camera 3 obtains the image of the current range value of the pipette gun 1, it directly recognizes the integer value and the decimal scale value in the range value. Since the decimal scale value has not returned to zero, the integer value may not be facing the scale observation window 11, so this embodiment needs to invest more cost in identifying the integer value and the decimal scale value to ensure the accuracy. However, during the identification process, the number of control times for rotating the range dial 12 is reduced, the operation time is shortened, and the efficiency of range adjustment is accelerated.

Abstract

The invention discloses an adjusting method of the range of a pipette. The adjusting method comprises the following steps: setting a preset range value; acquiring an image of the current range value of the pipette; recognizing the range value in the image; and rotating a range rotary disc according to the current range value and the preset range value. The range of the pipette is adjusted to the preset range value by acquiring the image of a scale observation window of the pipette, recognizing the range value of the current pipette and then rotating the range rotary disc by a specified angle,so that convenience is brought for following direct operation and use. The application also provides an adjusting device of the range of the pipette applicable to the above adjusting method of the range of the pipette.

Description

technical field [0001] The invention relates to the field of experimental instrument operation, in particular to a method and device for adjusting the range of a pipette gun. Background technique [0002] A pipette gun is an instrument for accurately pipetting a small amount or a small amount of liquid in a laboratory. When in use, often due to fatigue of operators working for a long time or differences in reading habits of different operators, errors in the liquid extraction process are often caused. In order to improve the accuracy of the pipette and improve work efficiency, more and more laboratories use mechanical equipment to automate the operation of the pipette. [0003] Since the volume required for each pipetting is not uniform, the volume range of the pipette will be adjusted according to the needs from time to time. Now common pipettes on the market, such as Thermo Fisher Scientific, Eppendorf, Gilson and other brands, all adjust the volume of the pipette by rot...
