Backlight Module Insertion Clamp Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembling process of liquid crystal display devices is cumbersome and prone to damage, particularly when turning over the backlight module to fix the screen driving board on the backside, which is laborious and risky, especially for large-size products like televisions.
Innovation Solution
A backlight module design featuring a fixing member and insertion clamp system that allows the circuit board to be inserted and fixed between the fixing member and the insertion clamp without overturning the module, simplifying the assembly and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the backlight module is turned over to fix the screen driving board on the back side, then the circuit board can be fixed, but the assembling process becomes cumbersome and laborious, and damage to the liquid crystal panel is likely to occur
Solution Approach 1:
The fixing structure is divided into a fixing member fixed to the backplane and a separate insertion clamp. This segmentation allows the circuit board to be inserted and fixed through a dedicated insertion channel without requiring overturning of the entire backlight module, thereby simplifying the assembling process and avoiding damage to the liquid crystal panel.
Solution Approach 2:
The insertion clamp acts as an intermediary component between the fixing member and the circuit board. It provides a clamping portion that directly secures the circuit board in place through the insertion channel, eliminating the need for overturning operations and reducing the risk of damage to sensitive components like the liquid crystal panel.
2Ease of manufacture
If the backlight module is turned over to fix the screen driving board, then the circuit board can be fixed, but the assembling process becomes laborious
Solution Approach 1:
The fixing member is pre-fixed to the backplane, and the insertion clamp is pre-positioned with its clamping portion aligned to receive the circuit board. This preliminary arrangement allows the circuit board to be directly inserted and secured through the insertion channel without requiring time-consuming overturning operations, thereby reducing overall assembling time.
3Reliability
If the backlight module is turned over to fix the screen driving board, then the circuit board can be fixed, but damage to the liquid crystal panel is likely to occur
Solution Approach 1:
By segmenting the fixing system into a fixing member and a separate insertion clamp with a dedicated insertion channel, the design allows the circuit board to be secured without overturning the backlight module. This eliminates the mechanical stress and risk of damage to the liquid crystal panel that would otherwise occur during overturning operations.
Solution Approach 2:
The insertion clamp serves as an intermediary that provides a safe, dedicated path for inserting and securing the circuit board. Its clamping portion directly holds the circuit board in place through the insertion channel, avoiding the need for overturning and thereby preventing damage to the liquid crystal panel and other sensitive components.
