Electronic scale calibration line

Abstract

Provided is an electronic scale calibration assembly line. By means of the electronic scale calibration assembly line, the problems that an existing electronic scale calibration assembly line is low in efficiency, high in labor consumption and high in labor intensity are solved. The electronic scale calibration assembly line is characterized in that a centralizer device is arranged on the pre-assembly and centralizing station, a turnover mechanism is arranged on the turnover station, a mobile beam calibration device or crossed beam calibration device is arranged and corresponds to a conveyor belt of a lifting conveying mechanism, and optoelectronic switches are arranged at the junctions of the stations. The electronic scale calibration assembly line has the beneficial effects that automatic alignment, automatic turnover, automatic lifting and automatic calibration are achieved under control of multiple hydraulic cylinders in the whole process, the electronic scale calibration efficiency is improved, and the labor intensity and labor cost of operation workers are reduced; and four standard weights of the calibration device are controlled by the hydraulic cylinders to be adjusted upwards, downwards, leftwards, rightwards, forwards and backwards in a stepless mode, the application range is wide, and the calibration assembly line high in degree of automation is provided for large electronic scales with the area being 800*800 mm-2000*3000 mm and the weighing capacity being 500-3000 kg.

Description

technical field [0001] The invention belongs to the technical field of electronic scale calibration, in particular to an electronic scale calibration assembly line. Background technique [0002] Electronic scales must be calibrated before leaving the factory. The calibration method of the electronic scale is to place the electronic scale on the horizontal platform, place the standard weights on the four corners of the weighing platform of the electronic scale, read the value to measure the error, and perform calibration. In the prior art, there are two ways of calibrating electronic scales: adding weights manually and adding weights mechanically. The manual weight adding method is that the operator puts the weight on the weighing pan, reads, calibrates, removes the weight, and repeats such simple actions; the mechanical weight adding method is to add weights one by one through multiple cylinder time-sharing operations On the weighing pan, calibration and zeroing are perfor...
