Description

Technical Field

[0001] The invention relates to the technical field of experimental instruments, and in particular to a full-automatic volume-fixing instrument. Background Art

[0002] A volumetric flask is a precise instrument used to prepare solutions with a certain concentration of a substance. It is a pear-shaped flat-bottomed glass bottle with a slender neck and a ground glass stopper. There is a scale on the neck. When the volume in the bottle reaches the mark at the specified temperature, its volume is the indicated volume.

[0003] In conventional chemical analysis, it is a routine step to adjust the volume of a volumetric flask. Since it is cumbersome to perform volume adjustment and liquid addition with a handheld volumetric flask, especially in the case of continuous large-scale volume adjustment, the volume adjustment often fails due to operator fatigue or paralysis. Therefore, some volume adjustment and liquid addition devices for volumetric flasks have appeared on the market. Although the existing volume adjustment and liquid addition devices for volumetric flasks can meet the volume adjustment and liquid addition needs of volumetric flasks, it is still necessary to manually place the volumetric flasks into the volumetric flask volume adjustment and liquid addition devices one by one, and take them out after the liquid addition and volume adjustment are completed and put in the next one again. It cannot work continuously and automatically, and still needs manual operation by the operator. Especially in the case of continuous large-scale volume adjustment, the operator is required to repeatedly place and take out the volumetric flask, which wastes manpower and is time-consuming and labor-intensive, and cannot meet the requirements of modern automated chemical analysis.

[0004] Therefore, a fully automatic volumetric instrument is designed to solve the above problems. Summary of the invention

The No. 1 distance sensor is fixed on the front-and-rear moving assembly. The No. 1 distance sensor and the No. 2 distance sensor are arranged relatively up and down to judge the height of the gripper rising and falling.

[0008] The forward and backward moving assembly includes a second motor and a second slide rail arranged in front and back, the second motor has a lead screw connected to a second slider, the second slider is fixedly connected to the connecting member, and the second slider moves along the second slide rail; two ends of the second slide rail are respectively provided with a third distance sensor and a fourth distance sensor arranged in front and back relative to each other, so as to judge the distance of the gripper moving forward and backward;
