Glass Sheet Gripping Head for Stable Corner Working
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses struggle to effectively hold and stabilize glass sheets with non-rectangular shapes, particularly at vertices with sharp or rounded edges, leading to poor quality finishes, dimensional inaccuracies, and potential breakage during processing.
Innovation Solution
An apparatus with a stabilizer device featuring rotatable and adjustable gripping members, allowing for precise angular orientation and multi-axis movement to securely grip sheets of any shape, including those with sharp or rounded vertices, using a central control unit to optimize positioning and tool wear compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rollers are used to sandwich the sheet at the perimeter edge, then the sheet can be held and stabilized during working, but the rollers lose contact with non-rectangular sheets having sharp or rounded vertices, causing poor quality finish and dimensional inaccuracies
Solution Approach 1:
The stabilizer device incorporates jaws with opening-closing movement that can dynamically adapt to different sheet shapes and vertex geometries. The jaws transition from a static roller configuration to a dynamic gripping mechanism that maintains contact with sharp and rounded vertices throughout the working process, ensuring both stability and precision for non-rectangular sheets
Solution Approach 2:
The stabilizer device changes its operational parameters by transitioning from roller contact to jaw gripping. The jaws can adjust their opening and closing movements to accommodate varying vertex radii and sheet geometries, maintaining optimal contact pressure and position throughout the working process to prevent vibrations and ensure dimensional accuracy
2Device complexity
If the stabilizer device uses fixed rollers, then the structure is simple, but it cannot correctly hold sheets with different shapes and vertices, leading to sheet breakage during working
Solution Approach 1:
The stabilizer device incorporates jaws with opening-closing movement that can dynamically adapt to different sheet shapes and vertex geometries. The jaws transition from a static roller configuration to a dynamic gripping mechanism that maintains contact with sharp and rounded vertices throughout the working process, ensuring both stability and precision for non-rectangular sheets
Solution Approach 2:
The stabilizer device is designed to handle multiple sheet shapes and vertex types using the same jaw mechanism. The jaws can universally accommodate rectangular, triangular, and other polygonal shapes with both sharp and rounded vertices, eliminating the need for different stabilizer configurations for different sheet geometries
3Device complexity
If the working head is fixed in position, then the apparatus structure is simpler, but it cannot follow the profile of the sheet at corners, resulting in poor quality work
Solution Approach 1:
The working head is made rotatable about a vertical axis, allowing it to dynamically change its angular orientation to follow the profile of the sheet at corners and vertices. This rotational capability enables the working tools to maintain proper engagement with the sheet edge throughout corner working operations, ensuring consistent quality regardless of sheet geometry
