Solution Overview
Problem
The existing methods for manufacturing display modules face challenges in efficiently discharging foreign substances, such as adhesive ingredients, when peeling a release film from a polarizing plate, especially in confined spaces, leading to increased defective attachment rates and reduced yield due to limited suction efficiency and the need for frequent nozzle repositioning.
Innovation Solution
An apparatus with a separator having a flow path for discharging foreign substances, coupled with a suction unit, which includes a peeling part, a scattering preventing part, and a vacuum ejector or pump, allows for efficient suction and discharge of foreign substances without the need for a separate nozzle, maintaining suction efficiency regardless of space constraints and adapting to different panel models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate suction device with a nozzle is installed to suck foreign substances, then foreign substances can be removed from the attachment region, but the suction efficiency is degraded due to limited space and the need to continuously change nozzle position
Solution Approach 1:
The suction unit is integrated directly into the separator structure, merging the suction function with the existing separator component. This eliminates the need for a separate suction device with movable nozzle, maintaining suction efficiency while removing foreign substances from the attachment region between display panel and polarizing plate
Solution Approach 2:
A suction hole is formed in the separator to serve as an intermediary pathway, allowing foreign substances to be suctioned through the separator structure itself. This intermediary channel enables effective foreign substance removal without requiring external nozzle positioning
2Manufacturing precision
If a separate suction device with a nozzle is used, then foreign substances can be suctioned, but it is necessary to continuously change the installation position of the nozzle according to panel model changes
Solution Approach 1:
The separator with integrated suction hole serves multiple functions: it acts as a separator between the release film and display panel, and simultaneously functions as a suction device for foreign substance removal. This universal design eliminates the need to adjust nozzle positions for different panel models
Solution Approach 2:
By merging the suction function into the separator structure, the system becomes adaptable to different panel models without requiring positional adjustments. The integrated design maintains effectiveness across various panel sizes and configurations
3Area of stationary object
If the attachment portion of display panel and polarizing plate is small, then the assembly is compact, but the space for positioning the suction nozzle is limited
Solution Approach 1:
The suction hole in the separator acts as an intermediary that eliminates the need for direct nozzle positioning in the confined attachment region. Foreign substances are removed through the separator structure rather than requiring space within the attachment region itself
Solution Approach 2:
The suction function is extracted from the attachment region and relocated to the separator structure. This removes the spatial conflict between the attachment region and nozzle positioning requirements
