Display Assembly Detaching Jig with Suction and Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for detaching display assemblies, which involve separating the backlight module and display panel, often result in non-uniform forces applied to the display panel, leading to issues such as breakdown or cracking, and deformation of the backlight module, thereby reducing the success rate of separation.
Innovation Solution
A jig comprising a fixing module to secure the backlight module and an absorbing module with suction cups to uniformly absorb the display panel, allowing for controlled external forces to separate the modules while minimizing deformation and cracking, along with a heating module to reduce sealant viscosity for easier detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hands are used to directly separate the backlight module and display panel, then the operation is simple, but the display panel is subject to non-uniform forces causing breakdown or crack
Solution Approach 1:
The patent introduces a separation device as an intermediary tool between the operator and the display assembly. This device includes a suction cup that uniformly contacts the display panel and a pulling mechanism that applies force through the separation device rather than directly to the panel, thereby distributing forces uniformly and preventing breakdown or cracking while maintaining operational simplicity
Solution Approach 2:
The patent employs a suction cup mechanism that utilizes pneumatic principles to attach to the display panel. By creating a vacuum or negative pressure within the suction cup, the device achieves uniform contact and force distribution across the panel surface, eliminating the non-uniform forces that occur during manual separation and significantly improving detachment success rate
2Device complexity
If hands are used to directly separate the backlight module and display panel, then no additional equipment is needed, but the backlight module deforms and films displace
Solution Approach 1:
The separation device serves as an intermediary that distributes pulling forces uniformly across the display panel through the suction cup mechanism. This uniform force distribution prevents concentrated stresses that would cause backlight module deformation and film displacement, while the device itself remains relatively simple in structure
Solution Approach 2:
The patent changes the parameter of force distribution from non-uniform (manual handling) to uniform (suction cup contact). By modifying how force is applied - specifically through the surface area and distribution pattern provided by the suction cup - the device protects the backlight module structure while requiring only minimal additional equipment
3Reliability
If uniform forces are applied to separate the display assembly, then the success rate of detachment improves, but additional equipment is required
Solution Approach 1:
The patent utilizes pneumatic principles through a suction cup mechanism that achieves uniform force distribution with minimal structural complexity. The suction cup creates a vacuum seal on the display panel surface, allowing the pulling force to be distributed evenly across the contact area, thereby improving detachment success rate while keeping the device design simple
Solution Approach 2:
The patent replaces direct manual mechanical handling with a pneumatic-suction-based mechanical system. Instead of grasping or pinching the display panel with fingers (which creates point loads), the suction cup provides distributed contact through atmospheric pressure differential, achieving uniform force application with a simple device structure
