Press Brake Camera Layout for Accurate Bending Without Robot Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bending systems have limited operating range due to insufficient separation of camera and illumination units from the workpiece, restricting the degree of freedom in processing while maintaining accuracy.
Innovation Solution
The bending system includes an image pickup unit positioned above and anterior to the setting area, with first and second illumination units located on the left and right front sides, respectively, allowing adjustable irradiation directions to cover the entire pallet area, thereby preventing interference and increasing the robot's operating range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera and illumination units are positioned close to the predetermined setting area, then the processing accuracy of bending is ensured through proper imaging, but the operating range of the bending robot is limited due to interference with the camera or illumination units
Solution Approach 1:
The camera is repositioned from a conventional lateral position to an oblique upper direction position, utilizing three-dimensional space more effectively. This spatial reconfiguration allows the camera to capture the workpiece from above while maintaining sufficient distance from the robot's operating path, thereby resolving the conflict between imaging quality and robot mobility.
Solution Approach 2:
The illumination system is divided into multiple illumination units positioned at different locations (left and right sides of the setting area). Each illumination unit independently illuminates specific regions, allowing comprehensive coverage of the workpiece while maintaining spatial separation from the robot's operational space, thus preventing interference.
2Illumination intensity
If the camera is positioned above the predetermined setting area, then the image pickup area is adequately illuminated, but the bending robot's degree of freedom is restricted due to potential interference with the camera
Solution Approach 1:
The camera is positioned in the oblique upper direction, utilizing vertical and lateral dimensions simultaneously. This three-dimensional positioning allows the camera to maintain an optimal imaging angle while being sufficiently distant from the robot's horizontal operating path, eliminating interference while preserving imaging quality.
Solution Approach 2:
Multiple illumination units are introduced as intermediary elements that provide necessary lighting to the image pickup area without requiring the camera to be positioned close to the robot's operational space. The illumination units act as mediators, delivering light to the workpiece from positions that do not interfere with robot movement.
