Deburring Apparatus Using Visual Sensor Ridge Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring apparatuses face challenges in achieving high precision and efficiency in detecting and removing burrs from cut objects, particularly when the objects are large or have complex shapes, as they often require manual movement and limited visual field capabilities.
Innovation Solution
A deburring apparatus equipped with a robot, a visual sensor, and a relative movement mechanism, where a controller generates deburring operation programs based on detected ridge data from the visual sensor, allowing the deburring tool to move along a locus defined by the detected burrs, enabling precise deburring without moving the object from the support, thus reducing deburring time and improving precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire object is placed within the visual field for detection, then detection precision is improved, but the device cannot accommodate large or complex-shaped objects
Solution Approach 1:
The detection process is divided into multiple segments by moving the visual sensor to different positions and angles. The controller captures ridge data at multiple locations and synthesizes them into complete deburring paths, allowing large or complex-shaped objects to be detected with high precision without requiring the entire object to fit in a single visual field.
Solution Approach 2:
The system transitions from a static two-dimensional visual field to a three-dimensional detection approach by moving the visual sensor in multiple directions. This enables comprehensive detection of complex-shaped objects by capturing data from various spatial perspectives and reconstructing the complete geometry.
2Ease of operation
If manual movement is used to position objects for deburring, then flexibility is maintained, but deburring time increases
Solution Approach 1:
The system replaces manual mechanical positioning with an automated robot that executes pre-calculated deburring paths. The controller generates precise motion commands based on detected ridge data, enabling high-speed automated deburring while maintaining flexibility through adaptive path generation for different object geometries.
Solution Approach 2:
The system dynamically adjusts deburring parameters such as robot motion speed, tool path coordinates, and processing sequence based on the detected object geometry. This allows automated high-speed processing while adapting to various object shapes and sizes, maintaining flexibility without manual intervention.
3Ease of operation
If the object is moved from the support for deburring, then access to all surfaces is improved, but positioning precision and processing time are affected
Solution Approach 1:
Instead of moving the object from the support, the system inverts the approach by moving the visual sensor and robot around the stationary object. This maintains the object's precise positioning on the support while enabling comprehensive detection and deburring of all accessible surfaces through coordinated motion of the sensing and processing equipment.

AI summary
A deburring apparatus including: a robot that uses a deburring tool to deburr an object supported by a support in a machine tool, a visual sensor, a relative movement mechanism for causing relative movement between the visual sensor and the object supported by the support; and a controller, wherein the controller is configured to conduct: an operation process that operates the relative movement mechanism based on a visual sensor relative movement program for controlling an operation of the relative movement mechanism so that a ridge of the object supported by the support is detected by the visual sensor during the relative movement; and a deburring operation program generation process which generates a deburring operation program by using the detected ridge obtained by the visual sensor when the relative movement mechanism is operated based on the visual sensor relative movement program.
