Jig Information Setting for Welding Workpiece Cross-Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current manufacturing process for welding new workpieces requires significant operator effort in designing jig information, as automation of this process has not been adequately addressed, leading to increased worker-hours.
Innovation Solution
A method and device that recognize new workpiece cross-section information at the clamping position and retrieve similar information from existing workpieces to set jig information, reducing the need for manual creation of jig design information by associating selected jig information with positional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If jig information is created manually for every new workpiece, then the accuracy and completeness of jig design information is ensured, but the worker-hours and time required for preparatory operations increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically retrieving and pre-processing jig information from similar existing workpieces before the actual jig design is needed. The cross-section recognition unit and information retrieval unit prepare candidate jig information in advance, reducing the time required for manual creation while maintaining design accuracy through automated comparison and selection of similar workpiece data.
2Productivity
If automation is introduced to reduce manual jig information creation, then worker-hours are reduced, but the complexity of the system increases
Solution Approach 1:
The system creates simplified copies of existing jig information from similar workpieces rather than developing entirely new jig designs. The information retrieval unit copies relevant jig parameters and design data from the database, which are then adapted to the new workpiece. This copying approach automates the process while keeping system complexity manageable by leveraging existing proven designs.
3Productivity
If existing jig information is reused for new workpieces, then the number of preparatory steps is reduced, but the adaptability to new workpiece geometries may be compromised
Solution Approach 1:
The system applies local quality by selectively adapting jig information based on the specific characteristics of the new workpiece. The cross-section recognition unit identifies unique features of the new workpiece, and the information setting unit selectively modifies only the necessary portions of the retrieved jig information to match these local characteristics. This ensures high adaptability while maintaining the efficiency benefits of reusing existing jig data.

AI summary
On the basis of location information which signifies a clamp location of a jig with respect to a new workpiece, new workpiece cross-section information is recognized in the clamp location. Next, a search is carried out among existing workpiece cross-section information for information similar to the recognized new workpiece cross-section information. Next, jig information is selected which is linked to the found workpiece cross-section information. Next, the selected jig information and the location information are linked and set to new workpiece design information.
