Chucking Assembly for Glass Substrate Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting glass laminated substrates often result in damage to the glass layer and non-uniform hole shapes due to the generation of glass chips and debris, as well as vibrations of the cutting apparatus.
Innovation Solution
An apparatus featuring a chucking assembly with a paramagnetic chucking plate, lever, piston, and elastic member, which uses vacuum pressure and electrostatic attraction to securely fix the hole cutting apparatus on the substrate, reducing vibrations and ensuring a uniform hole shape by employing materials like iron, nickel, or aluminum and silicone rubber for the chucking pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting methods are used to cut holes in glass laminated substrates, then the cutting process can be completed, but glass chips and debris are generated causing damage to the glass layer
Solution Approach 1:
The patent extracts and removes glass chips and debris from the cutting area using a suction device during the cutting process. The suction device includes a suction hole that draws out generated debris, preventing it from damaging the glass layer and ensuring clean cutting results.
Solution Approach 2:
The patent introduces a suction device as an intermediary element between the cutter and the glass layer. This mediator captures and removes harmful glass chips and debris before they can cause damage, resolving the contradiction between completing the cut and preventing damage.
2Manufacturing precision
If the cutting apparatus is not firmly fixed, then the apparatus structure remains simple, but vibrations occur during cutting causing non-uniform hole shapes
Solution Approach 1:
The patent applies preliminary action by firmly fixing the chucking assembly to the glass laminated substrate before the cutting operation begins. The suction device creates a vacuum that secures the apparatus in position, preventing vibrations during cutting and ensuring uniform hole shapes.
Solution Approach 2:
The patent replaces traditional mechanical fixation systems with a vacuum-based suction system. The suction device uses negative pressure to hold the apparatus firmly in place, eliminating vibrations without requiring complex mechanical clamping structures.
3Manufacturing precision
If the chucking pad is rigid, then the structure is simple, but it causes damage to the glass layer during positioning
Solution Approach 1:
The patent employs a flexible chucking pad made of elastic material instead of a rigid structure. This flexible pad conforms to the glass surface without causing damage, providing gentle yet secure positioning during the cutting process.
