Portable automatic calibrating device for electronic balance

Abstract

The invention discloses a portable electronic balance automatic calibrating device, which belongs to the technical field of metrological calibration, and is characterized in that a workbench assembly, a three-dimensional hanging assembly and an electromechanical cabinet are combined, and then a connecting part, a servo motor, a lifting support unit and other parts are correspondingly arranged and matched to work. On the basis of reducing the volume of the automatic calibration device and improving the convenience of the automatic calibration device, the levelness and the stability of the electronic balance in the calibration process are fully ensured, and the rapid and automatic calibration of the electronic balance is realized. The portable electronic balance automatic calibration device is simple in structure, reasonable in component layout, small in overall size, high in portability, capable of meeting reliable application in different use environments, capable of automatically completing the calibration process according to regulation requirements, is improved in working efficiency of electronic balance calibration and saves the calibration cost. In addition, influence of human factors in the calibration process is avoided, the calibration accuracy of the electronic balance is improved, and the electronic balance has good application prospect and popularization value.

Description

technical field [0001] The invention belongs to the technical field of measurement verification, and in particular relates to a portable electronic balance automatic verification device. Background technique [0002] Electronic balances are traditional weighing instruments that are widely used in various industries such as trade settlement, environmental sanitation, and biomedicine. Because it is widely used and is closely related to the people's livelihood, it is generally used as a strong inspection measuring instrument, so the traceability of the electronic balance's value is very important. [0003] At present, there are more than one million pieces of electronic balances each year that need to be verified by metrological technical institutions at all levels to ensure the accuracy of electronic balance work. In general, the verification of electronic balances is done manually in the verification laboratory; at the same time, there are a lot of simple and repetitive task...

AI Technical Summary

Problems solved by technology

In general, the verification of electronic balances is done manually in the verification laboratory; at the same time, there are a lot of simple and repetitive tasks in the verification process of electronic balances, and the verification items cover repeatability, indication error, There are a large number of weight grabbing operations for multiple detection indicators such as eccentric loads, which makes the entire detection process very time-consuming and labor-intensive, and the labor cost is high

Moreover, the results of manual verification are closely related to the operating level and operating status of the verification personnel, and there are problems such as inconsistent verification quality, low verification efficiency, and high verification cost.
