Bundled-bar label welding system based on machine vision

Abstract

The invention relates to a bundled-bar label welding system based on machine vision. The system involves a data acquisition module, a label printer, a visual acquisition module, an upper computer, a controller, a label queuing mechanism and a welding stud queuing mechanism, wherein the data acquisition module is used for acquiring bar information of bundled bars with a label to be welded in real time; the label printer is used for printing the bar information on the label; the visual acquisition module is used for acquiring end face data information; the upper computer is used for generating astud continuing instruction and a label continuing instruction and determining a welding position according to the end face data information; the controller is used for generating a corresponding control signal according to the stud continuing instruction and the label continuing instruction; the label queuing mechanism is used for queuing printed labels in order and conveying the labels to a label output hole; the welding stud queuing mechanism is used for queuing a plurality of welding studs in sequence and conveying the welding studs to a welding stud output hole; and after a robot obtainsthe label and the welding nail, welding is conducted according to the welding position. According to the system, the phenomenon of wrong label pasting can be prevented, manual input and potential safety hazards are reduced through automatic stud continuing and label continuing, accurate positioning is achieved, the welding effect is attractive and neat, falling is not prone to happening, and theproduction efficiency is improved.

Description

technical field

[0001] The invention relates to the field of automatic control, in particular to a machine vision-based welding system for bundled bar signs. Background technique

[0002] At present, the sign welding of bundled bars mainly adopts the method of manual welding. In this way, the welder holds a welding torch, puts a welding stud on the end of the welding torch, passes the welding stud through the sign hole, and independently finds the bundled bars. A bar with a good end surface on the machine, press the welding nail tightly on the end surface of the bar, pull the trigger, and complete the welding operation.

[0003] In this way of manual welding of signs, electric sparks and dazzling white light will be generated when the signs are welded, so welding workers need to wear protective clothing and protective masks to avoid injury. With the improvement of the country's economic level, people generally pursue jobs with a beautiful environment, low labor intensity, a...
