Purpose

Fillet welding is one of the most widespread types of welding in the industry, which is still carried out manually or automated by contact. This paper aims to describe an online programming system for noncontact fillet welding robots with “U”- and “L”-shaped structures, which responds to the needs of the Fourth Industrial Revolution.

Design/methodology/approach

In this paper, the authors propose an online robot programming methodology that eliminates unnecessary steps traditionally performed in robotic welding, so that the operator only performs three steps to complete the welding task. First, choose the piece to weld. Then, enter the welding parameters. Finally, it sends the automatically generated program to the robot.

Findings

The system finally managed to perform the fillet welding task with the proposed method in a more efficient preparation time than the compared methods. For this, a reduced number of components was used compared to other systems: a structured light 3 D camera, two computers and a concentrator, in addition to the six-axis industrial robotic arm. The operating complexity of the system has been reduced as much as possible.

Practical implications

To the best of the authors’ knowledge, there is no scientific or commercial evidence of an online robot programming system capable of performing a fillet welding process, simplifying the process so that it is completely transparent for the operator and framed in the Industry 4.0 paradigm. Its commercial potential lies mainly in its simple and low-cost implementation in a flexible system capable of adapting to any industrial fillet welding job and to any support that can accommodate it.

Originality/value

In this study, a robotic robust system is achieved, aligned to Industry 4.0, with a friendly, intuitive and simple interface for an operator who does not need to have knowledge of industrial robotics, allowing him to perform a fillet welding saving time and increasing productivity.

工业 4.0 机器人角焊在线编程系统

目的

角焊是业内应用最广泛的焊接类型之一,目前仍采用人工或接触自动化方式进行。本文旨在描述一种具有“U”形和“L”形结构的非接触角焊机器人在线编程系统,以响应第四次工业革命的需求。

设计/方法/方法

在本文中,作者提出了一种在线机器人编程方法,该方法消除了传统机器人焊接中执行的不必要步骤,使操作员只需执行三个步骤即可完成焊接任务。首先,选择要焊接的部件。然后,输入焊接参数。最后,它将自动生成的程序发送给机器人。

发现

与比较方法相比,该系统最终能够以更有效的准备时间使用所提出的方法执行角焊任务。为此,与其他系统相比,使用了更少的组件:结构光 3D 相机、两台计算机和一个集中器,以及六轴工业机械臂。系统的运行复杂度已尽可能降低。

实际影响

据作者所知,没有科学或商业证据表明在线机器人编程系统能够执行角焊工艺,简化工艺,使其对操作员完全透明,并符合工业 4.0 范式。它的商业潜力主要在于其在一个灵活的系统中的简单和低成本的实施,该系统能够适应任何工业角焊工作和任何能够适应它的支持。

原创性/价值

在这项研究中,实现了符合工业 4.0 的机器人稳健系统,为不需要工业机器人知识的操作员提供友好、直观和简单的界面,使他能够执行角焊,从而节省时间并提高生产力.
