Resilient Roller Assembly for Borderless Display Frame Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of borderless display devices to backing frames poses challenges due to the lack of a bezel, leading to issues with applying precise forces to secure the display screen without causing damage from excessive or shock forces.
Innovation Solution
A roller arrangement connected to a robot assembly, featuring a first and second plate with resilient members to absorb shocks, and a rotary actuator for controlled movement, applies force to the display screen edges using rollers, ensuring precise and controlled force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roller is used to apply force to the display screen during assembly, then the display screen can be securely attached to the frame, but shock or excessive force may be applied causing damage
Solution Approach 1:
A resilient member (spring) is pre-installed between the first plate and second plate to provide cushioning before force application. The spring absorbs shock and excessive force during the rolling operation, preventing damage to the display screen while maintaining secure attachment capability.
2Productivity
If automated roller arrangement is used for assembly, then productivity increases, but complexity of the device increases
Solution Approach 1:
The roller arrangement is segmented into distinct functional components: a first plate for robot connection, a second plate for roller support, and a resilient member for force management. This segmentation allows each component to perform its specific function independently, simplifying the overall system design and control while maintaining automated productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The roller arrangement effectively absorbs shocks and applies consistent forces to the display screen edges, preventing damage and ensuring secure attachment to the backing frame, while also enabling automated and precise assembly processes.
Implementation Method 1
at least one resilient member arranged between the first plate and the second plate to connect the first plate and the second plate to each other such that the first plate and the second plate are spaced from each other, whereby the resilient member can absorb a shock or excessive force applied to at least one of the first plate and the second plate
Implementation Method 2
The one or more resilient members absorb shock or excessive force, typically by compression as the first and second plate move towards each other when a force is applied by the roller to the display screen during assembly

AI summary
A roller arrangement is provided for a machine for applying a force to a display screen during assembly of the display screen to a frame. The roller arrangement has a first plate, for connecting the roller arrangement to a robot assembly, and a second plate. A roller is supported by the second plate. The roller can rotate and apply a force to a display screen during assembly of the display screen to a frame. At least one resilient member is arranged between the first plate and the second plate to connect the first plate and the second plate to each other such that the first plate and the second plate are spaced from each other. The resilient member can absorb a shock or excessive force applied to at least one of the first plate and the second plate.
