Suction Jig Groove for Gasket Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for handling gaskets with a carrier film, particularly for fuel batteries, face challenges in separating the gasket main body from the carrier film due to the small cross-sectional shape, leading to twist and unsatisfactory handling operability, and suction leakage occurs when using conventional suction jigs.
Innovation Solution
A gasket handling method utilizing a suction jig with a suction groove and elastically deformable porous material, where the suction groove corresponds to the gasket's planar and cross-sectional shape, allowing for precise suction and separation of the gasket main body from the carrier film, even with small cross-sectional dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gasket cross-sectional shape is set small to about 1 mm to a few mm, then the gasket can satisfy lower cost requirements, but twist easily occurs during conveyance and stacking, resulting in unsatisfactory handling operability
Solution Approach 1:
A carrier film is introduced as an intermediary substance to hold the gasket main body during conveyance and stacking. The carrier film prevents twist by providing external support and maintains the gasket's positional stability without requiring changes to the gasket's small cross-sectional dimensions, thus resolving the contradiction between cost-effectiveness and handling operability
2Productivity
If a conventional suction jig is used to separate the gasket main body from the carrier film, then separation can be achieved, but suction leakage occurs due to the small cross-sectional area of the gasket
Solution Approach 1:
The suction jig's suction surface is designed with locally varied properties: a recessed portion that corresponds to the gasket's cross-sectional shape, creating a localized suction zone. This localized design concentrates the suction force on the small cross-sectional area of the gasket, preventing suction leakage while maintaining reliable separation capability
3Ease of operation
If the suction groove shape corresponds to the gasket's planar and cross-sectional shape, then precise suction is achieved preventing twist, but the suction jig structure becomes more complex
Solution Approach 1:
The suction groove is designed with local quality by creating a recessed portion that specifically corresponds to the gasket's cross-sectional shape only where needed for precise suction. The rest of the suction jig structure remains simple and standardized, thus achieving handling precision without excessive structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method effectively prevents twist and improves handling operability by ensuring secure suction and separation of the gasket main body from the carrier film, reducing suction leakage and enhancing the handling of gaskets with small cross-sectional shapes.
Implementation Method 1
the suction surface is formed with a suction groove having a shape that corresponds with a planar shape of the gasket main body, the suction groove being formed with a plurality of suction paths at a required interval over the entire periphery; and separating the gasket main body from the carrier film by fixing the carrier film, and suctioning one surface in a thickness direction of the gasket main body to the suction groove with a suction force from the suction paths in the suction jig
