Panel Inspection Fixture With Adjustable Probes and Shared Backlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD panel inspection fixtures require separate designs for different specifications due to varying probe positions and the inability to share a backlight module across panels, leading to inefficiencies in inspection operations.
Innovation Solution
A panel inspection device with adjustable probe assemblies and a shared backlight module that can accommodate LCD panels of varying sizes by sliding probes along grooves and using elastic components for precise alignment, allowing for universal inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate inspection fixtures are designed for different LCD panel specifications, then probe contact precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The inspection fixture is designed with adjustable probe assemblies that can be repositioned along the edges of the carrier plate, allowing a single fixture to accommodate multiple LCD panel specifications. The probe assemblies can be adjusted to different positions and angles to match various panel sizes and contact point locations, eliminating the need for separate fixtures for different panel types.
Solution Approach 2:
The probe assemblies are made adjustable and reconfigurable rather than fixed, allowing dynamic adaptation to different inspection requirements. The probes can be moved along grooves and repositioned on the carrier plate edge, enabling the same fixture to precisely contact panels of varying specifications while maintaining measurement precision.
2Illumination intensity
If separate backlight modules are used for different LCD panel specifications, then illumination uniformity is improved, but loss of substance and resource waste increase
Solution Approach 1:
A single backlight module is designed to serve multiple LCD panel specifications through the adjustable carrier plate configuration. The carrier plate can be repositioned and reconfigured to accommodate different panel sizes while utilizing the same backlight source, thereby avoiding the need to manufacture and dispose of multiple specialized backlight modules.
Solution Approach 2:
The functionality of multiple specialized backlight modules is merged into a single universal backlight module combined with an adjustable carrier plate system. This consolidation allows one backlight module to provide uniform illumination across various panel specifications by adjusting the panel positioning rather than requiring separate dedicated modules for each panel type.
3Manufacturing precision
If fixed probe positions are used in inspection fixtures, then manufacturing precision is improved, but adaptability to different panel specifications deteriorates
Solution Approach 1:
The probe assemblies are designed with adjustable positioning mechanisms that allow them to be moved along grooves and repositioned on the carrier plate edge. This dynamic adjustability enables precise positioning for each specific panel being inspected while maintaining the capability to adapt to different panel specifications, combining precision with versatility.
Solution Approach 2:
The probe system is divided into multiple independent probe assemblies that can be individually adjusted and repositioned. Each probe assembly can be independently positioned along the carrier plate edge to match the specific contact requirements of different panel specifications, allowing precise positioning without requiring a completely different fixture design.
4Reliability
If multiple inspection fixtures are manufactured for different panel types, then inspection reliability is improved, but productivity and efficiency deteriorate
Solution Approach 1:
A single inspection fixture with adjustable probe assemblies and carrier plate can reliably inspect multiple LCD panel specifications, eliminating the need to manufacture, maintain, and switch between multiple specialized fixtures. This universality maintains inspection reliability through precise adjustable positioning while significantly improving productivity by allowing operators to inspect different panel types using the same equipment.

AI summary
A panel inspection device comprises an inspection plate, a carrier plate, a backlight module, a bracket assembly, and a first probe assembly. The inspection plate has a first edge and a second edge. The carrier plate is disposed on the inspection plate, forming an opening with the first edge and the second edge. The backlight module corresponds to the opening. The bracket assembly comprises a first bracket, which is disposed on the first edge and includes a first sliding groove. The first probe assembly includes a plurality of first probes. The first probe assembly is slidably disposed in the first sliding groove and is movable between a first position and a second position. When the first probe assembly is in the second position, the first probes correspond to the inner side of the first edge.
