Transfer Roller Film Alignment for Precise Sticking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sticking devices face challenges in accurately adjusting the posture of the transfer roller, which affects the conveyance of both the lamination film and the member to be stuck, making it difficult to achieve precise sticking of the film piece.
Innovation Solution
A sticking device with a transfer roller that includes a moving unit and a sticking film piece adjusting unit, comprising a rotation angle, width direction, and inclination adjusting units, allows for precise positioning and posture adjustment of the film piece on the transfer roller, independent of the roller's posture adjustments, ensuring accurate alignment with the member to be stuck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transfer roller is brought into contact with both the lamination film feed roller and the member-to-be-stuck feed roller, then the sticking function is achieved, but the conveyance of the lamination film and the member to be stuck is influenced when adjusting the roller posture
Solution Approach 1:
The patent divides the transfer roller's operational zones into distinct transfer region (contacting lamination film) and sticking region (contacting member to be stuck), allowing independent adjustment of each region's contact pressure and position. This segmentation enables posture adjustment without affecting the other conveyance processes.
Solution Approach 2:
The transfer roller is designed with dynamically adjustable contact positions and pressures in different regions. The roller can be relatively moved to adjust contact points, and the contact pressure can be independently controlled in the transfer region versus the sticking region, enabling flexible posture adjustment while maintaining stable conveyance.
2Manufacturing precision
If the transfer roller posture is adjusted to improve sticking accuracy, then the sticking precision improves, but the conveyance stability of the lamination film and member to be stuck deteriorates
Solution Approach 1:
The patent applies different contact characteristics to different regions of the transfer roller. The transfer region has specific contact pressure and position optimized for film transfer, while the sticking region has different characteristics optimized for adhering to the member. This local differentiation allows posture adjustment for precision without compromising overall conveyance stability.
Solution Approach 2:
The system performs preliminary positioning and alignment adjustments before the actual sticking operation. By pre-adjusting the transfer roller's contact positions and postures in a controlled manner, the system establishes stable conveyance conditions beforehand, then makes fine adjustments for sticking precision without disrupting the already-stabilized conveyance.

AI summary
A sticking device includes: a transfer roller that transfers a sticking film piece to a circumferential surface, and sticks the sticking film piece to a member to be stuck; a moving unit that moves the transfer roller; and a sticking film adjusting unit that adjusts a position and a posture of the sticking film piece on the circumferential surface of the transfer roller at a position away from both a transfer region A1 and a sticking region A2. The sticking film piece adjusting unit includes: a rotation angle adjusting unit that adjusts a sticking start position of the sticking film piece; a width direction adjusting unit that adjusts a position of the sticking film piece; and an inclination adjusting unit that adjusts an angle of the transfer roller.
