Problems solved by technology

However, the calibration process is cumbersome. Since the weights are manually taken and placed, it is easy to accidentally touch the weights during the process, which will cause corrosion of the weights and affect the accuracy of the calibration.

Abstract

The invention discloses a self-calibration balance free of manual calibration. The self-calibration balance comprises a base, a weighing pan, a weighing sensor, an electromagnet, a positioning column and a weight, wherein the weighing sensor comprises a weighing part used for generating deformation and a mounting part used for mounting and fixing, the weighing pan is fixedly connected with the weighing part of the weighing sensor, and the mounting part of the weighing sensor is fixedly connected with the base; the electromagnet mounting part is mounted at the bottom of the bearing part; the electromagnet is fixedly mounted on the electromagnet mounting part; the positioning columns are fixedly installed on the base and distributed at the two ends of the electromagnet. the weight is mounted between the base and the electromagnet; Based on the invention, through the calibration function of the main controller, the electromagnet can be controlled to be opened or closed so as to generate or lose magnetism. Meanwhile, under the guiding action of the positioning column, the weights can be automatically loaded and unloaded, so that the self-calibration function of the balance is realized.

Description

technical field [0001] The invention relates to the field of detection instruments, in particular to a self-calibrating balance without manual calibration. Background technique [0002] A balance scale is a tool used to weigh objects, which is widely used in our production and life. The balance scale can effectively weigh daily necessities or industrial supplies, thus facilitating our daily life and industrial production. Before the existing balance scale weighs an item, it is necessary to perform calibration and calibration operations on the balance. [0003] The current balance calibration method on the market is generally to perform a zero adjustment operation when the balance is empty. Then put the quantitative weight on the weighing pan of the balance, and perform a calibration operation of the corresponding mass again. However, the calibration process is cumbersome, because the weights are manually taken and placed, and it is easy to accidentally touch the weights du...
