Solution Overview

Problem

Existing welding condition management systems require manual collection and summarization of welding data, leading to inefficiencies and reduced operation rates due to the need for manual creation of welding condition records, which can differ from actual conditions used in production.

Innovation Solution

A system and method that includes a terminal device and robot control device to acquire and correct teaching programs, generate welding history data, and extract and output welding conditions, automating the management of welding conditions and reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual collection and summarization of welding data is performed, then welding condition records can be created, but operation rates decrease and manual effort increases

Engineering Contradiction:

Improvewelding condition managementVSAvoidoperation rate

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The system enables automatic self-service by having the robot control device autonomously create welding condition records by extracting data from teaching programs and welding history data, eliminating the need for manual collection and summarization while maintaining complete welding condition documentation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of collecting and summarizing welding data is replaced with an automated information processing system that extracts welding conditions from teaching programs and welding history data, substituting human labor with automated data processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If manual creation of welding condition records is performed, then welding conditions can be documented, but stop times for facility operations increase

Engineering Contradiction:

Improvewelding condition documentationVSAvoidstop time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically creating welding condition records during or immediately after the welding process using pre-collected teaching program data and welding history data, eliminating the need for post-process manual documentation and reducing facility stop times

Inventive Principle:

Principle #10Preliminary action

3Productivity

If automated data collection is implemented, then operation rates improve, but system complexity increases

Engineering Contradiction:

Improveoperation rateVSAvoiddata management system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The robot control device performs multiple functions by both controlling the welding robot and automatically creating welding condition records, eliminating the need for separate manual documentation systems and reducing overall system complexity while improving operation rates

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A welding condition management method is a welding condition management method performed by a terminal device, and the welding condition management method includes: acquiring a first teaching program for causing a welding robot to execute welding, a second teaching program created by correcting the first teaching program, and welding history data related to the welding executed by using the second teaching program; and extracting and outputting a welding condition at the time of the welding based on the first teaching program, the second teaching program, and the welding history data.
