Board Production Line Proxy for Continuous Information Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In board production lines, the absence of communication capabilities in certain work devices disrupts the transmission of information related to board type and quality defects, preventing effective use of this information.
Innovation Solution
A board production line with a shared folder system that divides storage areas according to the number of work devices, allowing information to be transferred among these areas, and a management proxy section that accesses the shared folder on behalf of devices without direct access, ensuring uninterrupted information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a work device without communication function is disposed in the board production line, then device complexity is reduced, but information transmission is interrupted
Solution Approach 1:
The patent introduces a proxy device as an intermediary between work devices without communication functions and the shared folder system. This proxy device communicates with the shared folder on behalf of the non-communicating work device, enabling information transmission without requiring the work device itself to have communication capabilities. The proxy device reads and writes information to the shared folder, bridging the gap between simple work devices and the information management system.
2Loss of information
If all work devices are equipped with communication function, then information transmission is maintained, but device complexity increases
Solution Approach 1:
The patent segments the communication function from the work devices themselves, placing it instead in a separate proxy device. This allows work devices to remain simple without communication hardware, while the proxy device handles all communication tasks. The system is divided into: (1) simple work devices that perform operations, (2) a proxy device that handles communication, and (3) a shared folder system that stores information.
3Loss of information
If a shared folder with multiple storage areas is implemented, then information organization is improved, but device complexity increases
Solution Approach 1:
The shared folder is designed as a universal information storage system that serves all work devices through a single interface. Instead of implementing separate communication and storage systems for each work device, the shared folder provides centralized information management that benefits all devices. The proxy device uses this universal system to manage information for multiple work devices, reducing overall system complexity.

AI summary
In a board production line having multiple work devices arranged to transfer a board from upstream to downstream and perform a predetermined operation on the board, the board production line comprising: a shared folder having storage areas configured to store board-related information, the storage areas being multiply divided according to the number of the work devices, and transferring the board-related information among the storage areas, in conjunction with transferring the board, with a first work device capable of accessing the storage areas among the multiple work devices, and a management proxy section configured to access the shared folder in place of a second work device which cannot access the storage areas, and configured to manage the board-related information so that the board-related information can be transferred among the storage areas.
