Solution Overview
Problem
Existing ACF attachment devices with multiple rollers require manual replacement of ACF, leading to increased replacement time and contamination risks.
Innovation Solution
A film treating apparatus comprising a film feeder, processor, collector, fixed support unit, and variable support unit that facilitates easy film replacement by applying tension and guiding the film along rollers, reducing friction and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual replacement of ACF is used in existing devices, then device structure is simple, but replacement time increases and contamination risk increases
Solution Approach 1:
The support unit is designed to move dynamically between a first position (where the film is inserted) and a second position (where the film is processed). This dynamic movement enables automatic film replacement without manual intervention, resolving the contradiction by automating the replacement process while maintaining a relatively simple device structure.
Solution Approach 2:
The device enables self-service automatic film replacement through the coordinated movement of the support unit and the film feeding mechanism. The system automatically feeds the film from the reel, tensions it appropriately, and positions it for processing without requiring manual operation, thereby reducing replacement time while keeping the device structure manageable.
2Manufacturing precision
If film is fed without tension control, then device structure is simple, but film processing quality deteriorates
Solution Approach 1:
The support unit applies tension to the film in advance during the feeding process, before the film reaches the processing position. This preliminary tensioning ensures that the film is properly positioned and tensioned throughout the feeding process, improving processing quality while using a relatively simple tension control mechanism.
Solution Approach 2:
The tension applied to the film is controlled by adjusting the position of the support unit. By changing the positional parameter of the support unit between the first and second positions, the system optimizes film tension for different stages of the feeding process, thereby improving film processing quality without requiring a complex tension control mechanism.

AI summary
A film treating method includes feeding a film from a film feeder, moving the film along an outer circumference of a fixed support unit, which supports the film and guides the movement of the film, applying tension to the film by moving a variable support unit from a first surface of the film toward a second surface of the film, processing the film, and collecting the film.
