Laminator Turnover Abutment for Top-Down Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the process of sticking a film onto a substrate, such as in OLED metal packaging, the borne object may be inclined, leading to a falling-off risk due to uneven suction by the laminator's suction structures, as it is typically sucked from the bottom up.
Innovation Solution
The laminator incorporates a turnover abutment with opposite bearing surfaces, each equipped with suction structures, allowing the surface to flip and suck the object from the top down, ensuring all suction structures engage, and a film laminating device for simultaneous lamination and release, along with a support member driven by a servo motor for precise object handling and a cutting device for efficient film management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laminator sucks the borne object from the bottom up, then the suction structures can engage with the object, but the object may be inclined and cause falling-off risk due to uneven suction
Solution Approach 1:
The patent inverts the conventional bottom-up suction approach by implementing top-down suction. The turnover abutment flips 180 degrees to position the bearing surface with suction structures above the borne object, allowing suction to act from the top downward. This inversion ensures that even inclined objects are suctioned uniformly from above, eliminating the falling-off risk associated with bottom-up suction on inclined surfaces.
Solution Approach 2:
The patent employs a dynamic turnover mechanism that allows the abutment to rotate between horizontal and vertical positions. The turnover drive enables the abutment to flip 180 degrees, transforming the suction direction from bottom-up to top-down. This dynamic repositioning ensures consistent suction engagement regardless of the object's initial orientation, improving both suction reliability and object handling stability.
2Productivity
If a single bearing surface is used for suction, then the structure is simple, but only one object can be handled at a time
Solution Approach 1:
The turnover abutment is designed with dual bearing surfaces that can alternately serve as suction surfaces. By flipping 180 degrees, the same abutment structure enables handling of multiple objects sequentially, effectively doubling the handling capacity. The first bearing surface and second bearing surface both具备 suction structures, allowing the system to maintain simplicity while achieving multi-object capability through temporal multiplexing.
3Ease of operation
If the abutment remains horizontal, then the structure is stable, but the bearing surface cannot be positioned above the object for top-down suction
Solution Approach 1:
The abutment is equipped with a turnover drive mechanism that enables it to rotate between horizontal and vertical positions. This dynamic capability allows the bearing surface to be positioned above the object for top-down suction, providing operational flexibility. The turnover mechanism, while adding some complexity, enables the system to adapt its configuration based on the specific operational requirements, allowing controlled suction direction.
