Robot Teaching Point Reuse Across Programs to Cut Search Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot teaching operations are inefficient due to the need to search for and correct multiple teaching points, especially when similar or identical points are taught in different robot programs, leading to potential operational errors and reduced efficiency.
Innovation Solution
A teaching device and system that allows for the reuse of previously taught teaching points across different robot programs, including selection, association, and correction of these points to enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a search is conducted to determine which robot program has taught an already taught teaching point, then the accuracy of teaching point identification is improved, but the efficiency of the teaching operation is impaired
Solution Approach 1:
The system performs preliminary actions by displaying teaching points from other robot programs in advance on the generation screen before the actual teaching operation. This allows the operator to visually identify and select reusable teaching points without conducting time-consuming searches, thereby resolving the contradiction between identification accuracy and operational efficiency
Solution Approach 2:
The system creates a visual copy of teaching points from other robot programs and displays them on the generation screen. This copying mechanism enables operators to reference existing teaching points across different programs, eliminating the need for searches while maintaining accurate identification and reuse of teaching points
2Adaptability or versatility
If multiple teaching points at the same position are treated as different points, then the flexibility of robot programming is improved, but the complexity of correction operations increases
Solution Approach 1:
The system implements a universal teaching point management approach where teaching points from different robot programs are displayed and managed in a unified interface. The teaching point selection unit can select from teaching points across multiple programs, and the reuse unit handles the reuse operation universally, thereby reducing correction complexity while maintaining programming flexibility
Solution Approach 2:
The teaching point selection unit acts as an intermediary between the multiple teaching points at the same position and the robot program generation process. It provides a standardized selection interface that simplifies the correction operation while preserving the ability to differentiate and selectively reuse teaching points across different programs
3Productivity
If teaching points from other robot programs are reused, then the productivity of robot program generation is improved, but the risk of operational errors increases
Solution Approach 1:
The system implements feedback through the teaching point display control unit that displays teaching points from other robot programs on the generation screen, allowing the operator to visually verify the selected teaching point before reuse. This visual feedback mechanism reduces operational errors while maintaining high productivity by enabling informed selection of reusable teaching points
Solution Approach 2:
The system applies preliminary anti-action by providing visual display and confirmation mechanisms before the teaching point reuse operation occurs. The operator can preview the teaching point information and confirm the selection, preventing potential errors before they happen while still enabling efficient reuse of teaching points from other programs

AI summary
This teaching device comprises: a user interface unit capable of displaying a creation screen for a robot program; a teaching point display control unit for controlling displaying of previously taught teaching points on the creation screen; a teaching point selection unit for selecting a specific teaching point from the displayed teaching points; and a teaching point reuse unit for reusing the selected teaching point as a new teaching point for a robot program being created. The previously taught teaching points include at least one of a teaching point taught previously for the robot program being created and a teaching point taught previously for another robot program different from the robot program.
