Seal Affixing System with Segmented Suction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In seal affixing systems using porous adsorption end effectors, air leakage occurs as the seal progresses, leading to reduced adsorption power and potential generation of turbulent spots like creases or air bubbles in the affixed seal.
Innovation Solution
The system includes a porous adsorption end effector with adsorption pores arranged along multiple directions, sectioned into suction regions, and a controller that individually controls suction power to each region, allowing for sequential stopping of suction in regions where seal adsorption is unnecessary, thus preventing air leakage and turbulent spots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single vacuum source is used for the porous adsorption end effector, then the device complexity is reduced, but air leakage occurs and adsorption power deteriorates as the seal progresses
Solution Approach 1:
The adsorption face is divided into multiple suction regions (first suction region, second suction region, etc.), each connected to the single vacuum source through separate flow paths. This segmentation allows selective control of vacuum application to different regions, preventing air leakage and maintaining adsorption power without requiring multiple vacuum sources.
2Reliability
If suction is continuously applied to all suction regions, then the seal is securely held, but air leakage occurs in regions where the seal has already been affixed, causing turbulent spots
Solution Approach 1:
The vacuum application to each suction region is made dynamic and selective. The controller opens or closes vacuum application to specific suction regions based on the real-time position of the seal and the affixing progress. This dynamic control ensures the seal is securely held in active regions while preventing air leakage and turbulent spots in regions where affixing is complete.
3Ease of operation
If the seal is affixed while being held by adsorption, then the affixing operation is simplified, but creases or air bubbles are generated in the seal due to air leakage
Solution Approach 1:
The controller receives feedback about the seal position and affixing progress, and uses this information to selectively control vacuum application to different suction regions. This feedback mechanism ensures that vacuum is maintained only where needed for holding the seal, while preventing air leakage in completed regions, thereby avoiding creases and air bubbles while maintaining ease of operation.

AI summary
In a seal affixing system, adsorption pores are arranged plurally along a first direction and a second direction on an adsorption face, and the plurality of adsorption pores are sectioned into a first suction region, a second suction region, and a third suction region containing a plurality of adsorption pores from a downstream side to an upstream side along a movement direction, and a controller controls a suction power generator to individually suck the first suction region, the second suction region, and the third suction region. According to the seal affixing system, a turbulent spot will not be generated in the affixed seal.
