Abstract

The invention relates to a glass measuring vessel capacity automatic calibration device and calibration method, a measuring vessel fixing clamp is connected with a jacking mechanism and a translationmechanism, the jacking mechanism drives the measuring vessel fixing clamp to move in the vertical direction, and the translation mechanism drives the measuring vessel fixing clamp to move in the transverse direction; a water tank is arranged below the measuring vessel fixing clamp; a water absorption assembly and a water discharge assembly control the glass measuring vessel to be measured to absorb water or discharge water, and an image acquisition device is arranged on the side face of the measuring vessel fixing clamp and used for obtaining the liquid level height in the glass measuring vessel. An upper computer is connected with the image acquisition device in a wired or wireless mode, and the upper computer judges liquid level information in the glass measuring vessel through pattern recognition. According to the invention, automatic verification of the glass measuring vessel can be realized, the labor cost is reduced, personal errors are avoided, the detection precision is high, the repeatability is good, and the verification efficiency and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and relates to an automatic capacity verification device and a verification method of a glass measuring vessel. Background technique [0002] As a precision liquid measuring instrument, the pipette is widely used in various analysis experiments. Whether the pipette is reliable or not directly affects the accuracy of the analysis and test results. In order to ensure the accuracy of liquid measurement, it is necessary to manually detect it based on the measurement method. This is the most reliable and accurate verification method at present. For this reason, the automatic verification process of glass gauges has been limited for a long time. In recent years, the output of glass measuring instruments has increased, and the demand for verification has increased. The original manual detection method can no longer meet the requirements of the Metrology Institute for verification efficiency ...
