Method and system for screening weighing equipment based on mold weight

Abstract

The invention discloses a weighing apparatus screening method and a weighing apparatus screening system based on mould weight. The method comprises the following steps: first, receiving an input signal, exporting a variety of parameters, and sending a working signal for starting two CCD cameras; second, receiving pictures taken by the CCD cameras, and working out the volume values of moulds; third, numbering the moulds, and establishing a corresponding relationship between the numbers and the volume values of the corresponding moulds; fourth, working out the weight values of moulds, and establishing a corresponding relationship between the weight values and the volume values of the corresponding moulds; and finally, receiving a signal sent by a material sensor indicating that each mould passes through the material sensor, exporting the weight value corresponding to the mould number corresponding to each signal, comparing the weight values with the maximum weighing weight of weighing apparatuses, and making a material shifting device work. The invention provides a set of system for automatic weighing apparatus screening according to mould weight. The problem that screening is of low accuracy and is prone to error due to the dependence on artificial experience in the prior art is solved, the accuracy of screening is ensured, and damage to weighting apparatuses is avoided.

Description

technical field [0001] The invention relates to a weighing equipment screening method and system, in particular to a weighing equipment screening method and system based on mold weight. Background technique [0002] In the process of mold production and manufacturing, the processed molds need to be weighed by weighing tools before they can be packaged and entered the market; however, because the actual weight of each mold is not known before weighing, especially for large molds, once the weight of the mold If the maximum weight of the weighing equipment is exceeded, not only the actual weight of the mold cannot be obtained, but in serious cases, it will cause damage to the weighing equipment, bring losses to the enterprise, and increase the consumption of the weighing equipment. Therefore, how to accurately select the suitable The weighing equipment is particularly important, and at present, the screening of weighing equipment is often carried out by the operator based on hi...

Problems solved by technology

[0002] In the process of mold production and manufacturing, the processed molds need to be weighed by weighing tools before they can be packaged and entered the market; however, because the actual weight of each mold is not known before weighing, especially for large molds, once the weight of the mold If the maximum weight of the weighing equipment is exceeded, not only the actual weight of the mold cannot be obtained, but in serious cases, it will cause damage to the weighing equipment, bring losses to the enterprise, and increase the consumption of the weighing equipment. Therefore, how to accurately select the suitable The weighing equipment is particularly important, and at present, the screening of weighing equipment is often carried out by the operator based on his own experience, so the requirements for the experience of the staff are high, and even experienced staff cannot guarantee The accurate weighing equipment is screened out every time. The accuracy and stability of the screening are not high, and it is easy to make judgment errors, resulting in damage to the weighing equipment.

[0003] At the same time, due to the need to manually move the materials to the weighing equipment, the labor intensity of the staff is high, especially for large molds, the requirements for the staff are higher, and the efficiency of manual operation is low, and the degree of automation is not high.
