Automatic vision-based labeling device for end faces of reinforcing steel bars in bundle

Abstract

An automatic vision-based labeling device for end faces of reinforcing steel bars in a bundle comprises a positive and negative pressure supply device (1), a machine vision device (2), a label printing and stripping integrated machine (3) and a labeling unit (4). The label printing and stripping integrated machine (3) is arranged below the front of an operation object which is the reinforcing steel bar bundle and next to the reinforcing steel bar bundle. The machine vision device (2) is arranged right in front of the reinforcing steel bar bundle. The positive and negative pressure supply device (1) is arranged on the left side of the front of the reinforcing steel bar bundle. The labeling unit (4) is arranged on the right side of the front of the reinforcing steel bar bundle. According to the complete device, machine vision is used for obtaining the central coordinates of the end faces of the reinforcing steel bars in the bundle, a robot is used for conducting automatic labeling, manual intervention is not needed, management is facilitated, and a foundation is laid for achieving internet+ intelligent production of iron and steel plants.

Description

technical field [0001] The invention relates to an automatic labeling device, in particular to a vision-based automatic labeling device, in particular to a device for automatically labeling the end face of each steel bar in a bundle of steel bars by using machine vision. Background technique [0002] The iron and steel industry has always been the basic industry of the national economy and plays a very important role in the development of the national economy. At the same time, the iron and steel industry is also an important source of raw materials for other important industries. It can be said that the development level of a country's industry largely depends on the development of the country's steel industry. The main finished products of the iron and steel industry include steel plates, steel bars, steel pipes, etc., among which steel bars are one of the main forms. The size and types of steel bars are complex and various, and steel manufacturers currently produce tens...

Problems solved by technology

[0003] The end face of the steel bar is generally marked on the steel bar production line. At present, the labels pasted on the end face of the steel bar are mainly self-adhesive labels. Pasting on the end face of the steel bar that has been cooled down, this method is not only inefficient, but also h
