Laminated Body Manufacturing System Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for manufacturing laminated bodies, such as liquid crystal display devices, face challenges in panel management, including abnormal panel detection, unequal panel preparation, and varying lot combinations, which affect efficiency and accuracy in the bonding process.
Innovation Solution
A manufacturing system and method that involves coating one panel with an adhesive in a first working region and bonding it with another panel in a second working region, using dedicated conveying devices and bonding devices to manage and align the panels as a set, ensuring precise alignment and bonding while allowing for flexible layout adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate conveying devices are used for each panel, then each panel can be conveyed independently for processing, but it becomes difficult to manage and align the panels as a matched set throughout the bonding process
Solution Approach 1:
The patent combines two separate conveying devices into a single integrated conveying device that conveys both panels simultaneously. This merging allows the panels to be managed as a matched set while maintaining independent processing capabilities, resolving the contradiction between ease of operation and manufacturing precision.
Solution Approach 2:
The conveying device is designed with multi-functionality to handle both panels in various configurations - conveying them side-by-side, one after another, or in different orientations. This universal design enables flexible panel management while ensuring precise alignment for bonding operations.
2Productivity
If panels are prepared in equal numbers in advance, then the bonding process can proceed smoothly, but it reduces flexibility in handling abnormal panels and varying lot combinations
Solution Approach 1:
The system employs dynamic panel preparation where panels are conveyed and processed in a flexible sequence rather than rigid pre-pairing. The conveying device can adjust to convey panels one after another or in pairs, and can handle abnormal panels by continuing to convey subsequent panels until a suitable match is found, maintaining both productivity and adaptability.
Solution Approach 2:
The system performs preliminary conveying and basic processing of panels before final bonding pairing. This allows panels to be prepared in advance to some extent for efficient processing, while still maintaining the flexibility to pair them dynamically based on quality checks and bonding requirements, rather than rigid pre-pairing.
3Reliability
If dedicated conveying devices are used in each working region, then processing conditions can be optimized for each region, but the system complexity increases
Solution Approach 1:
The patent employs a universal conveying device that serves multiple working regions (first and second working regions) with different processing functions. This single device is designed to convey panels through coating, drying, and bonding operations, maintaining reliable processing conditions in each region while reducing overall system complexity compared to having separate dedicated conveying devices for each region.

AI summary
A manufacturing system for manufacturing a laminated body by coating a first panel with an adhesive in a first working region and bonding the first panel coated with the adhesive and a second panel in a second working region includes a first conveying device in the first working region for conveying the first panel and the second panel, a coating device in the first working region for coating, with the adhesive, the first panel, a bonding device in the second working region for bonding the first panel and the second panel, and a second conveying device in the second working region for conveying the first panel and the second panel to the bonding device. The first conveying device and the second conveying device convey the first panel and the second panel to be bonded to each other as a set.
