Drying Agent Bag Shaping and Pushing Device for Wafer Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wafer packaging systems, the drying agent bag often falls apart before entering the aluminum foil bag and rebounds into the sealing part, causing air to enter the bag and compromising the storage of wafers.
Innovation Solution
A drying agent bag shaping and pushing device with a traverse moving rail, lifting frame, clamping cylinder, and material pushing mechanism that shapes and secures the bag to prevent it from falling apart and ensures complete sealing, utilizing a combination of clamping plates, bevel surfaces, and elastic materials to maintain stability and prevent air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drying agent bag is pushed into the aluminum foil bag without proper shaping and clamping, then the packaging process is faster, but the drying agent bag falls apart and rebounds into the sealing part causing air leakage
Solution Approach 1:
The drying agent bag undergoes preliminary shaping and positioning actions before being pushed into the aluminum foil bag. The positioning plate pre-forms the bag shape, and clamping plates pre-clamp the sides, ensuring the bag is properly prepared to prevent falling apart during the subsequent pushing operation and maintain sealing integrity.
Solution Approach 2:
The clamping mechanism is divided into multiple clamping plates that independently clamp different portions of the drying agent bag. This segmentation allows for more effective and distributed clamping force, preventing the bag from deforming or rebounding during the pushing process while maintaining overall structural integrity for proper sealing.
2Device complexity
If calipers only clamp the sides of the up-turned part without clamping the middle portion, then the clamping device structure is simpler, but the middle portion bulges outward causing the drying agent bag to fall apart
Solution Approach 1:
The clamping function is segmented into multiple clamping plates that can independently clamp different regions of the drying agent bag, including the middle portion. This allows comprehensive clamping of all critical areas without requiring a single complex clamping mechanism, thereby maintaining shape stability while avoiding excessive structural complexity.
Solution Approach 2:
The positioning plate acts as an intermediary element that not only shapes the drying agent bag but also serves as a clamping surface. By forming the bag shape against the positioning plate and using clamping plates to secure it, the system achieves stable clamping of the middle portion through a coordinated mechanism rather than a single complex component.
3Ease of manufacture
If the drying agent bag is not properly shaped before pushing, then the pushing process is simpler, but the bag gets squeezed on one side causing the middle portion to bulge and fall apart
Solution Approach 1:
The drying agent bag is preliminarily shaped by the positioning plate before the pushing operation. This pre-shaping action ensures the bag has the correct form and structure, preventing deformation during pushing while keeping the pushing mechanism itself simple. The preliminary shaping prepares the bag to withstand the pushing force without bulging or falling apart.
