Segmented Pressing Die With Load Feedback for Uneven Lid Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing technologies for integrated circuit elements with lids cannot simultaneously apply uniform pressure to areas of different heights, leading to varying pressures on portions with different heights and lack of control over applied load magnitude.
Innovation Solution
A pressing device with a lower pressing die and an upper pressing die equipped with plungers and a load measuring unit, allowing for precise control of pressure application through independent pressing block modules and load measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a horizontal pressing contact surface is used to press the lid, then the pressing operation is simple, but uniform pressure cannot be applied to areas of different heights
Solution Approach 1:
The pressing device divides the pressing contact surface into multiple independent pressing blocks corresponding to different height areas. Each pressing block can be independently controlled to press different regions of the lid, ensuring that each area receives appropriate pressure despite height variations.
Solution Approach 2:
The pressing blocks are designed to be movable rather than fixed, allowing them to adjust their position and pressing force dynamically. This enables the system to adapt to different height profiles of the lid and apply uniform pressure across all areas by independently controlling each pressing block's movement and force application.
2Productivity
If different heights of lid areas are pressed simultaneously, then the pressing process is efficient, but the magnitude of load applied cannot be controlled
Solution Approach 1:
The pressing device incorporates a load measuring unit that provides real-time feedback on the pressing force applied to each pressing block. This feedback mechanism allows the control system to monitor and adjust the load magnitude on each area independently, ensuring precise control while maintaining simultaneous pressing operation.
Solution Approach 2:
The load measuring unit acts as an intermediary between the pressing blocks and the control system. It translates the mechanical pressing force into measurable data, enabling the control system to precisely regulate the load magnitude applied to each area while maintaining efficient simultaneous pressing.
3Device complexity
If a single pressing surface is used, then the device structure is simple, but pressure distribution on varying height surfaces is uneven
Solution Approach 1:
Instead of using a single continuous pressing surface, the device employs multiple discrete pressing blocks that can be independently positioned and controlled. This segmentation allows each block to conform to specific height areas, achieving uniform pressure distribution while keeping each individual block structurally simple.
Solution Approach 2:
Each pressing block is designed with specific local characteristics suitable for its designated area. The pressing blocks can have different sizes, shapes, and pressing forces tailored to the specific height and area requirements of different regions, ensuring optimal pressure distribution across the entire lid surface.
