Description

Technical Field

[0001] The present invention relates to the technical field of mass measurement, and in particular to a mass measurement device and a measurement method thereof. Background Art

[0002] A mass measuring device is an instrument used to measure the mass of an object. It converts the mass of an object into digital or other readable forms through precise sensors and measurement techniques. It is widely used in laboratories, industrial production, commercial transactions and other fields. Common mass measuring devices include electronic scales, balances, mass sensors, etc. Electronic scales use electronic sensors and microprocessors for high-precision measurements, while balances measure by comparing the weights of objects on both sides. The accuracy, stability and sensitivity of mass measuring devices are crucial to ensuring the reliability of measurement results.

[0003] The Chinese patent with the announcement number CN220230700U discloses an improved mass meter. When the surface area of ​​the electronic scale needs to be increased to weigh large-shaped objects, the motor is started, and then the threaded rod in the rectangular groove is driven, so that the support plates at both ends extend outward through the through holes. When the support plates extend to the required position, the motor is turned off. At this time, the surface area of ​​the electronic scale increases, and objects larger than the original electronic scale can be placed, so that the surface area of ​​the electronic scale is increased to weigh large-shaped objects. The problem that the objects are large and small when weighing objects with electronic scales is solved, so that large-shaped objects cannot be completely piled on the electronic scale, so that the excess parts of the objects fall to the ground, and then the ground can provide upward support for the objects, which easily leads to inaccurate weight measurement of the objects. However, the existing device is difficult to protect the objects to be weighed when in use, which makes it easy for them to fall off from the support plate, so that errors are easily generated during measurement, affecting the accuracy and reliability of the measurement results. At the same time, the falling off of the measured object may cause the interruption of the measurement process, increase the time for repositioning and re-measurement, and reduce the overall operation efficiency.
