Curved Screen Laminating Apparatus with Flexible Pressing Mold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laminating apparatuses for curved screens often result in a poor laminating effect due to non-uniform pressure distribution, leading to issues like black spots and bubbles during the lamination process between the screen and the cover plate.
Innovation Solution
A laminating apparatus comprising a base, an elastic component, and a flexible pressing mold with a curved surface that extends into grooves on the side beams, ensuring uniform pressure application and increased contact area, allowing the screen to be laminated from the middle to the edges, thereby reducing gas trapped between the screen and the cover plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional laminating apparatus is used, then the lamination process can be completed, but the pressure distribution is non-uniform causing black spots and bubbles
Solution Approach 1:
The pressing mold is designed with a curved surface that matches the curvature of the screen, allowing uniform pressure distribution across the entire screen surface including edge portions. This curved design enables the pressing mold to conform to the screen geometry and apply consistent laminating pressure without creating black spots or bubbles.
Solution Approach 2:
The pressing mold is made from flexible silicone rubber material that can deform and adapt to the screen's curved surface. This flexibility allows the mold to maintain uniform contact and pressure distribution across the entire screen area, ensuring consistent laminating quality throughout the process.
2Strength
If the pressing mold is made rigid, then structural strength is improved, but contact area with the curved screen is reduced
Solution Approach 1:
The pressing mold is constructed from flexible silicone rubber that can deform to match the curved screen surface, maximizing the contact area between the mold and screen. This flexibility ensures complete surface contact while maintaining sufficient structural strength for effective laminating.
Solution Approach 2:
The pressing mold uses silicone rubber material that combines flexibility for conforming to curved surfaces with sufficient structural strength for applying uniform pressure during lamination, resolving the contradiction between rigidity and contact area.
3Ease of manufacture
If the edge portions of the pressing mold do not extend outward, then the structure is simpler, but gas trapped between screen and cover plate cannot be effectively removed
Solution Approach 1:
The pressing mold extends outward at its edge portions and features a curved surface design that allows the edges to reach toward the screen periphery. This extended curved structure effectively pushes trapped gas from the center toward the edges and out from between the screen and cover plate, preventing bubble formation.

Function Achieved in This Case
The solution ensures a uniform laminating force, reduces the occurrence of black spots and bubbles, and improves the overall lamination quality by maintaining consistent pressure and increasing the contact area between the screen and the cover plate.
