Description

Technical Field

[0001] The invention relates to the field of weights, and in particular to a detection device for rapid weight checking of weights. Background Art

[0002] In modern mass measurement, weights are standard measuring tools for mass value transmission. The mass value is based on the original platinum-iridium alloy kilogram preserved in the French International Bureau of Weights and Measures as the only reference. All countries divide weights into national kilogram standards, national kilogram secondary standards, kilogram working standards, and working standards composed of multiples and components of kilograms and various working standard weights. In order to ensure the accuracy and consistency of the value, standard weights are used to calibrate weighing equipment at home and abroad, that is, standard weights are used to simulate weighing and detect weighing data under uniformly distributed loads, eccentric loads and extreme loads, so as to realize the full performance measurement and detection of electronic weighing equipment (such as electronic price computing scales, electronic scales, etc.). As a standard weight, its own accuracy is in accordance with the requirements of the national verification regulations of JJG96-2004 "Weights", and a high-precision balance is required for measurement and transmission. The calibration of weights is currently at the manual calibration stage in the laboratory. Although high-precision analytical balances are used for weighing, processes such as grabbing are still mainly manual, and there is a risk of weights being scratched or falling and damaged during movement.

[0003] Existing weight check weighing is all manual check weighing, which is too slow and not suitable for large-scale check weighing. Summary of the invention
