Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems are not capable of automatically attaching elongated sealing materials to objects with complex surface shapes, as they are designed for planar rectangular labels and cannot accommodate the unique shape and orientation requirements of elongated sealing materials.
Innovation Solution
A sealing material attachment system utilizing a robot with movable suction pads and a base that allows for controlled suction and positioning, enabling the attachment of elongated sealing materials to complex surfaces by adjusting the angle and orientation of the suction pads to match the object's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot with fixed suction pads is used for attaching sealing materials, then the attachment process can be automated, but the system cannot adapt to complex surface shapes and elongated sealing material orientations
Solution Approach 1:
The suction pad base is designed to rotate and change orientation dynamically, allowing the suction pads to align with different directions of elongated sealing materials and adapt to complex three-dimensional surface shapes. This dynamic adjustment capability enables a single robotic system to handle various sealing material orientations and surface geometries that would otherwise require multiple specialized devices.
2Manufacturing precision
If multiple suction pads are used to attach elongated sealing materials, then the attachment precision can be improved, but the device complexity increases
Solution Approach 1:
The suction base is divided into multiple independent suction pads arranged in specific patterns, allowing each pad to independently attach to different portions of the elongated sealing material. This segmentation enables precise control over the attachment process, ensuring proper alignment and preventing wrinkles while maintaining manageable device complexity through modular design.
3Device complexity
If the suction pads are fixed in orientation, then the device structure is simple, but the system cannot accommodate sealing materials with different orientations on complex surfaces
Solution Approach 1:
The base structure incorporates rotational capability that allows it to change orientation dynamically during the attachment process. This enables the suction pads to align with the longitudinal direction of elongated sealing materials regardless of their orientation on complex three-dimensional surfaces, achieving high adaptability without requiring multiple fixed-orientation devices.

AI summary
In attachment system provided with an industrial robot having a hand movable at an arm tip, a base is attached to the hand. The base supports a plurality of suction pads such that angles of virtual suction surfaces including suction pad ends intersect each other in a hand operating space. Under control of a control device, the respective pads suction a sealing material at the respective suction surfaces, and the position and orientation of the base is controlled in the operating space such that partial suction surfaces face a designated attachment position on the object. Further, an attachment surface of the sealing material is partially attached to the designated attachment position on the object, in a state the sealing material to part of which the partial suction pads are suctioned is still faced to the designated attachment position. Such steps are repeated for the remaining attachment positions of the object.
