Screen Film Alignment Frame With Roller-Assisted Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing film-sticking devices require manual operation for attaching tempered glass films to electronic devices, leading to potential detachment and alignment issues, which complicates the process and reduces accuracy.
Innovation Solution
A film-sticking device with a movable positioning frame and roller assembly that allows for automated alignment and attachment of films to electronic devices, featuring a positioning box body with a placement slot, a movable positioning frame, and a roller assembly that slides over the screen to secure the film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used to mount the tempered film assembly on the film-sticking device, then the device structure can be simple, but the positioning film may detach from the tempered film, causing alignment failure
Solution Approach 1:
The film-sticking device is designed to automatically position and attach the tempered film assembly without requiring manual intervention. The positioning frame and roller assembly work together to self-align and secure the film, eliminating the need for operators to manually mount the assembly while preventing positioning film detachment
Solution Approach 2:
The positioning frame acts as an intermediary component between the tempered film assembly and the positioning box body. It provides a stable mounting interface that prevents the positioning film from detaching while enabling automatic alignment through its interaction with the roller assembly
2Manufacturing precision
If manual operation is used for film attachment, then the device structure remains simple, but film-sticking accuracy deteriorates due to misalignment
Solution Approach 1:
The positioning frame is pre-configured with the tempered film assembly in a predetermined position before the film-sticking process begins. This preliminary positioning ensures that when the roller assembly engages, the film is already aligned with the positioning box body, achieving high accuracy without requiring complex manual adjustment operations
Solution Approach 2:
The manual mechanical operation of positioning and aligning the film is replaced by an automated roller assembly mechanism. The roller assembly automatically engages with the positioning frame and secures the film in the correct position, eliminating manual alignment operations while maintaining high film-sticking accuracy
3Manufacturing precision
If automated roller assembly is used for film attachment, then film-sticking accuracy is improved, but the device complexity increases
Solution Approach 1:
The film-sticking device is divided into functionally independent segments: the positioning box body, the movable positioning frame, and the roller assembly. Each segment performs a specific function (positioning, mounting, and securing respectively), allowing for simplified individual components while achieving high overall precision through their coordinated operation

AI summary
A film-sticking device comprises a positioning box body (1) with a placement slot (2) for receiving an electronic device (not shown) with a screen to which film is to be stuck, and a positioning frame (3) movably, preferably pivotably, arranged on the positioning box body (1) for mounting the film-sticking assembly (7). This allows the film-sticking assembly (7) to be conveniently aligned with the screen of the electronic device. Preferably, a roller assembly (4) for pressing the film (7) onto the screen of the electronic device is slidably arranged on sliding rails (11) in the positioning box body. An elastic pad (6) may be provided, allowing the roller assembly (4) to transition from the positioning box body (1) to the screen of the electronic device. Positioning pins are ideally provided for engaging positioning holes provided on the film-sticking assembly (7).
