Conveying mechanism for comprehensively controlling weight, weight verification system and weight verification method

Abstract

The invention provides a conveying mechanism for comprehensively controlling a weight. The conveying mechanism comprises two door-shaped beams arranged side by side, and a horizontal transverse beam; a vertical longitudinal beam is arranged on the horizontal transverse beam; a manipulator is arranged at the end part of the vertical longitudinal beam; Y-axle guide mechanisms are respectively arranged on the two door-shaped beams; the horizontal transverse beam is provided with an X-axle guide mechanism; the vertical longitudinal beam is provided with a Z-axle guide mechanism; joint parts are respectively arranged on the X-axle guide mechanism and the Z-axle guide mechanism; and the manipulator includes a rotating section, multiple manipulators respectively connected with the rotating section, and a manipulator motor for driving the rotating section to rotate by 360 degrees. The manipulator has a single large fork with two stations, two large forks with four stations, a single small fork with two stations and double small forks with four stations; and each fork is a comb-shaped structure. The whole weight verification process is operated by set procedures, so that the personal error is eliminated, and the influence of linear drifting of a qualitative comparison instrument on the measurement result is effectively reduced or eliminated.

Description

technical field [0001] The invention relates to the field of weight verification, in particular to a weight verification system with an all-round control weight manipulator. Background technique [0002] Weights are weights that are used as standard weights, e.g. in a testing institute or in a correspondingly certified company, for the calibration of scales, especially precision scales, or for the calibration of other weights of a lower precision class . [0003] The precision of weights is defined by so-called precision classes. These accuracy classes determine the maximum error allowed for each. The accuracy class is divided into nine grades, among which, grade E 1 is the most accurate class of weights, and class M 3 is the least precise weight class. When weights are transferred between each other, the value of the higher class weight is always decisive, that is, a weight is followed by a weight of a higher precision class and compared with it to obtain its value . ...

Problems solved by technology

However, the error caused by the operator's operation or the misreading of the data will seriously affect the verification result of this manual detection device.

Especially the milligram group weights, because the milligram group weights are formed by bending metal wires in a specific shape and are small in size, it is very easy to cause deformation of the weights when the operator clamps them with a clip, thus affecting the detection of the weights. And milligram group weights are usually tested on a high-precision comparator of one ten-millionth, and any slight personnel error will seriously affect the test results
