Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet pasting devices face challenges in accurately and efficiently applying adhesive sheets to moving workpieces without compromising pasting performance, often requiring the workpiece to be stopped, which can lower efficiency.
Innovation Solution
A sheet pasting device equipped with a feeding unit, a holding unit, an attachment surface posture detecting unit, and a press unit that moves in sync with the workpiece, allowing the adhesive sheet to be oriented and positioned correctly relative to the workpiece's surface, enabling precise and continuous pasting without stopping the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the workpiece is stopped to paste the adhesive sheet, then the pasting accuracy is improved, but the productivity deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the holding member move in synchronization with the workpiece instead of keeping it stationary. The press unit moves the holding member along the workpiece's movement trajectory, allowing the adhesive sheet to be applied to a moving workpiece while maintaining accurate positioning through coordinated motion control.
Solution Approach 2:
The patent implements continuity of useful action by enabling continuous pasting operation without stopping the workpiece. The synchronized movement of the holding member with the workpiece allows the adhesive sheet application to continue throughout the workpiece's movement, eliminating idle stopping time and maintaining continuous productive operation.
2Productivity
If the workpiece moves during pasting, then the productivity is improved, but the pasting accuracy deteriorates
Solution Approach 1:
The patent employs feedback control through the attachment surface posture detecting unit that continuously monitors the workpiece's position and orientation. This detection information is used to adjust the holding member's movement in real-time, ensuring that the adhesive sheet is applied at the correct position and orientation even while the workpiece is moving.
Solution Approach 2:
The system dynamically adjusts the holding member's position and orientation to match the workpiece's movement. The press unit controls the holding member to move in synchronization with the workpiece, maintaining accurate relative positioning throughout the pasting process despite the workpiece's continuous motion.
3Device complexity
If a stationary holding member is used, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The patent transforms the stationary holding member into a dynamic, movable holding member that can follow the workpiece's movement. This dynamic capability allows the system to adapt to moving workpieces while maintaining relatively simple control through synchronized motion, achieving versatility without excessive complexity.
Solution Approach 2:
The movable holding member design provides universal applicability to both stationary and moving workpieces. The same holding member structure can operate in different modes - stationary for simple applications and moving for continuous production applications - making the device versatile without requiring multiple specialized components.
