Workpiece Feature Point Highlighting for Accurate Bending Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face challenges in correctly setting workpieces on bending machines due to numerous holes or difficult-to-identify features, leading to increased errors and defective products.
Innovation Solution
A workpiece display assistance device that generates an original model of the workpiece and creates matching models by rotation and inversion, extracts matching sections, and determines a feature point to highlight on the display screen, aiding the operator in correct positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the workpiece is displayed on the display screen without additional assistance, then the display device can show the workpiece image, but the operator cannot easily identify feature points when the workpiece has many holes or difficult-to-find features
Solution Approach 1:
The patent extracts the feature point information from the complete workpiece image and presents it separately through model comparison. By comparing the original model with matching models rotated by various angles, the system isolates and highlights only the relevant feature point that serves as a setting mark, removing unnecessary visual complexity from the display.
Solution Approach 2:
The patent adds a new dimension to the display by showing not only the workpiece image but also multiple rotational models (0°, 90°, 180°, 270°) and their matching sections. This multi-angle comparison approach provides spatial orientation information that helps the operator identify feature points from different perspectives, effectively adding dimensional context to the two-dimensional display.
2Ease of operation
If the operator relies on holes or features as marks for setting the workpiece, then the setting process can be guided, but when the number of holes is large or features are difficult to find, setting errors increase
Solution Approach 1:
The patent uses visual highlighting (analogous to color changes) to emphasize the feature point on the display screen. By displaying the matching section that corresponds to the feature point with distinctive visual characteristics, the system makes the feature point stand out from other holes and features, enabling easy identification without requiring the operator to search through numerous similar-looking elements.
Solution Approach 2:
The patent creates simplified model copies of the workpiece at different rotational angles and compares them to identify the correct orientation. Instead of requiring the operator to directly interpret the complex three-dimensional workpiece geometry, the system generates two-dimensional model representations that are easier to analyze and compare, thereby simplifying the feature point detection process.
3Reliability
If the bending machine operates without workpiece setting assistance, then the processing can proceed efficiently, but incorrect setting leads to defective products and reworking
Solution Approach 1:
The patent performs preliminary analysis of the workpiece model before the actual bending operation. By pre-calculating and displaying the matching sections and feature points on the screen before the operator begins setting the workpiece, the system provides advance guidance that prevents setting errors. This preliminary visualization step ensures correct orientation is identified before physical setting occurs.
Solution Approach 2:
The patent implements a feedback mechanism where the display screen shows the operator the correct feature point orientation based on model comparison. This visual feedback allows the operator to verify their setting against the displayed guidance, creating a closed-loop system that confirms correct positioning and reduces the likelihood of errors leading to defective products.

AI summary
A workpiece display assistance device according to one aspect includes: a first model generation unit that obtains shape data of a workpiece to be set, and generates an original model based on the shape data; a second model generation unit that generates a plurality of matching models by rotating and/or inverting the original model; an extraction unit that matches each matching model to the original model and extracts aligned portions of the respective matching models with the original model as matching sections; a model creation unit that creates a matching aggregate model by aggregating the matching sections in a state conforming to the original model and synthesizing the matching sections aggregated; a determination unit that compares the original model and the matching aggregate model and makes a determination of a feature point on the workpiece; and a display unit that displays the feature point in a highlightable manner, along with an image of the workpiece, on a display screen based on the determination result.
