OLED Mask Device Hollow Alignment Plates Welding Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of OLED mask plates, the intersection of strip alignment plates and support plates often blocks welding spots, requiring the removal and re-welding of alignment plates, which wastes material and disrupts alignment references, complicating subsequent alignment and evaporation processes.
Innovation Solution
The mask device incorporates alignment plates with hollow portions that allow welding spots on the support plate to be exposed, preventing blockage and enabling repair without removing the alignment plates, thus maintaining alignment stability and reducing material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If alignment plates are solid without hollow portions, then structural strength is improved, but welding spots become blocked and require removal and re-welding
Solution Approach 1:
The alignment plate is segmented by introducing hollow portions that divide the solid structure into sections, allowing welding spots to be exposed while maintaining overall structural integrity through the remaining solid portions
Solution Approach 2:
The hollow portion acts as an intermediary space that allows the welding tool to access the welding spot between the alignment plate and support plate, enabling repair without removing the alignment plate
2Ease of repair
If alignment plates are removed for welding repair, then welding spots become accessible, but alignment references are disrupted and material is wasted
Solution Approach 1:
The hollow portions are pre-formed in the alignment plates during manufacturing, enabling future welding repairs to be performed without removing the alignment plates, thus preventing material waste and preserving alignment references
3Ease of repair
If alignment plates are removed and re-welded, then welding spots become accessible, but alignment stability is compromised
Solution Approach 1:
By segmenting the alignment plate structure to include hollow portions, the design allows welding access while the alignment plate remains in place, preserving the stability of alignment references throughout the device
