Air Injection Pick-and-Place for Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-and-place technologies for display panels often cause damage due to strong suction forces or manual handling, leading to deformation, photo spacer skew, light leaks, scratches, and breakage.
Innovation Solution
A pick-and-place apparatus utilizing an air injection unit and a supporting unit with air injection and suction capabilities, along with a wedge-shaped inserting element, to lift and support display panels without direct force application, facilitating soft contact and minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sucking disk with strong suction force is used to prevent the display panel from falling, then the reliability of panel holding is improved, but the display panel suffers local deformation, PS skew, light leak, scratches, and circle-shaped marks
Solution Approach 1:
The patent introduces air as an intermediary medium between the holding device and the display panel. Instead of direct mechanical contact with a sucking disk, the system uses injected air to lift and support the panel through first openings (lifting the edge) and second openings (supporting the surface), eliminating direct force application that causes deformation while maintaining reliable holding
Solution Approach 2:
The patent applies pneumatic principles by using an air injection unit to inject air through openings in the holding device. The injected air creates a cushion that supports the display panel weight and prevents contact with the device surface, replacing the traditional suction-based pneumatic holding that causes damage
2Device complexity
If manual hands are used to pick and place the display panel, then the device complexity is reduced, but the productivity is low, cost is high, and the display panel is prone to deformation and complete breakup
Solution Approach 1:
The holding device is designed to automatically perform the picking and placing operations through the air injection system. The controller automatically controls the air injection unit to lift, move, and place the panel without manual intervention, making the system self-sufficient while maintaining simplicity in structure
Solution Approach 2:
The patent replaces the manual mechanical handling system with an automated pneumatic system. The air injection unit substitutes for human hands, providing consistent, controlled support to the panel throughout the handling process, eliminating the variability and potential for damage associated with manual operations while improving productivity
